The invention contemplates as a further object the provision of a swingable truck for supporting alined stub shafts having reduced portions adapted to interlock with spaced sides of a swingable loop retained in removable interlocking relation with the alined shafts by a spring actuated locking member rotatably carried by a fulcrum pin swingably carrying the truck.

rThe invention comprehends as a further object the provision of a truck swingably mounted on longitudinally disposed fulcrum means having a :shoulder cooperating to limit longitudinal displacement of the fulcrurn means in one direction, the truck having a swingable loop adapted to removably interlock with reduced portions of the stub shafts to prevent their lateral displacement and means rotatably associated with the fulcrum means adapted to disconnectablyA retain the swingable loop in an interlocking relation with the stub shafts.

The invention further comprehends the provision of a skate having complementary slidable iront and rear plate sections cooperating with an elongated ooit having a swingable manipulator for rotating the bolt to adjust relative displacement of the plate sections, the bolt having locking means for holding the manipulator in alinement therewith or substantially perpendicular thereto, the rear plate section being provided with a bifurcation .for removably interlocking or receiving an .intermediate portion of the manipulator to prevent transverse displacement thereof.

The invention has as a further object the provision of complementary slidable front and rear shoe supporting plate sections one of which includes an anchoring device for removably gripping a flexible strap against bodily transverse slippage relative to said sections and for rotatably supporting the elongated longitudinally disposed bolt common to the front and rear shoe supporting sections.

Fig. 13 is a sectien on the line i3 l3 of Fig. 12. Fig. 14 is a section on the line I-'l id of Fig. 12, and

Fig. 15 shows an inverted perspective View of a truck and a wheel disconnected therefrom.

The skate IU comprises front and rear complement-ary slidable plate sections Il and l2 to each of which is secured a channeled shaped member I3 each having spaced depending lugs or ears I4 provided with alined openings I5.

Siwingably cooperating with each channeled member I3 is a truck generally Adesignated I6 which comprises a yoke ll' having an integral depending hollow bead or knuckle I8 each provided with a pair of spaced slots I9 to form three depending alined hollow curved ears 29, 2I and 22 defining alined bearings for alined stub] shafts 23 each of which appropriately carry an antifrietionally supported roller wheel 24.

Each stub shaft 23 is provided with an anannular groove 25 dening a reduced portion 26 and a cylindrical integrally connected boss or enlargement 26 for spacing an adjacent Wheel from an outer ear of an associated knuckle and for limiting the insertion of arespective stub shaft therein.

Although a wheel is rotatable relative to its supporting stub shaft, the latter normally is non-rotatably sustained in its knuckle, being prevented from lateral displacement by a swingable clip, broadly denoted 21, which comprises Ya U shaped member 28 having lugs 29 and 30 extending in opposite directions and integral therewith. Lug 29 is provided with an opening 3I adapted to receive cylindrical shank of stud 32 iixedly secured to inclined wall 33 of an associated knuckle i6. Stud 32 is provided with an enlarged head 34 serving to limit downward displacement of lug 29, there being suflicient clearance between head 34 of the stud and an associated inclined wall 33 to permit slight movement of lug 29 therebetween when the lug or manipulating lip 39 is moved downwardly against the resistance of coiled springs 35 surrounding the spaced headed studs 36 fixedly carried by an associated yoke I1. It will be noted that each U shaped portion 28 is provided with integrally connected spaced extensions 31.

With clip- 28 closed as illustrated in Fig. 3, spaced extensions 31 are within spaced slots I9 and project into the spaced grooves 25 of the alined pair of stub shafts and accordingly interlock with the latter to prevent lateral or longitudinal displacement thereof.

If lipy 35 be depressed, its clip 21 tilts or pivots about its beaded stud 32 since the latter is loosely associated with opening 3| and spaced extensions 31 move out of annular grooves 25 of the alined stub shafts. Consequently by grasping a wheel and moving the latter outwardly its stub shaft which is bodily carried therewith may be slidably removed from the knuckle, for example, see Fig. 2, in which a rear stub shaft is shown disconnected from the rear truck.

In moving downwardly, lip 30 is guided by the spaced headed studs 36 which are disposed in spaced openings 38, and the lip is resisted against downwardly displacement by helicoidal springs 35. Furthermore, by reason of the loose connection between lug 29 with its associated stud 32, clip 21 may be considered as pivoted or swingable relative to its cooperating yoke I1.

With lip 3l] depressed, locking extensions 31 are clear of the bore defined by its slotted knuckle. Hence a stub shaft may be removed therefrom or a stuby shaft may be readily inserted therein. After insertion its associated boss 29 serves as stop means permitting the groove 25 of the stub shaft inserted into the bearing to automatically line upv with a slot I9 in the knuckle after which manual pressure is removed from lip 39 and the latter automatically is elevated due to the release of springs 35.V Consequently extensions 31 are elevated and enter corresponding grooves 25, interlocking with the walls thereof as previously pointed out to prevent lateral displacement.

According to the present invention, a shaft may be conveniently assembled with a truck` The operator simply depresses lip 39 to swing its clip 21 after which a stub shaft is slidably moved into the knuckle until such movement is resisted by its boss or flange 26. Lip 3B is manually released and an extension as 31 interlocks with the stub shaft thus inserted.

In the event a ball bearing 44 of a wheel breaks or becomes jammed, they frictionally engage its stub shafts, causing the latter to rotate with its wheel although normally a stub shaft is non-rotatably disposed in the knuckle.

Each yoke I1 of a truck I6 is provided with spaced upstanding lugs 4I, each having an opening 42 in registration with opening I5 of an adjacent lug I4 of channel I3, the registered or alined openings I5 and 42 receiving a reduced portion V43 of a fulcrum pin 44 which comprises headed ends 45. In effect each truck is swingably carried by a respective fulcrum pin 44, while the headed ends thereof and its intermediate portion form shoulders 49 and 41 straddling and interlocking with juxtapositioned depending and upstanding lugs I4 and 4I of channel I3 and its swingable truck to prevent longitudinal displacement of its fulcrum pin 4 I, which is straddled by a resilient rubber block 43 for absorbing impacts imparted tothe wheels as is well understood.

Referring now to the complementary plate shoe supporting sections, the rear section I2 is provided with an intermediate reduced portion 49 slidably receivable in the transverse slot 50 of the front plate section I I, it being noted, however, (see Fig. 8) that the forward part of reduced portion 49 is guided between sides of the front channeled member I3.

The rear portion 5I of the front plate sectionV Ii also reduced and is provided with spaced depending longitudinallyV extending flanges 52 which are slidably guided by the sides of the rear channeled member I3.

Disposed transversely of rear plate section l2 is an irregularly shaped bar or brace 53 having its central portion 54 bent inwardly forming a vertical channel 55 for receiving reduced smooth part 56 of a. threaded bolt 51 threadably interconnected with a vertical wall 58 of a strap anchor generally denoted 59 rigidly secured to and depending from the front plate section II. Brace 53 is provided with offset laterally extending terminals 69 each secured to rear plate section I2 by suitable rivets 6I.

Swingably carried at the rear end of bolt 51 is a manipulator 62 having a flattened inner end 63 disposed in a bifurcated part 64 of bolt 5 and transversely disposed pin 95 secured to bifurcated part E4 constitutes fulcrum means for pivotally sustaining flattened end 53 of manipulator 52 which may be automatically held in a vertical position by reason of the cylindrical tumbler 66 and associated spring 51 coniined in an axial bore in boltJ 5l, that is, manipulator 62 isl held in a retained and vertical position. Inv such position, key $2 is also prevented from transverse displacement relative to the rear section I2. To this end, the latter is provided with a pair of integrally and rearwardly extending spaced lugs 98 defining a slot 69, the walls of which are adapted to interlock or straddle ilattened terminal 33 of the manipulator 62.

It is apparent that plunger or tumbler 65 cooperates with a vertical face as 68 of flattened terminal 53 and holds or locks the latter in a vertical position substantially perpendicular to the rotatable bolt I1 and if the manipulator is interlocked with the spaced lugs 68, bolt 51 is prevented from `accidental rotation.

Where, however, it is desired to rotate bolt 5l, manipulator 82 is swung'downwardly relative to fulcrum pin 65. During this operation,l the retainer or tumbler 86 iirst moves inwardly until corner i8 is cleared and subsequently moves outwardly and cooperates with rectilinear face 1i,

ius holding or locking the flattened end or terminal of the manipulator in alinement with bolt 51. When disposed in alinement rotation oi the manipulator causes ro-tation of the bolt and consequently, front plate section II may be adjusted relative to rear plate section I2.

More particularly, if it is desired to adjust plate l sections 5I and I2 to take a large size shoe, the

key is disposed in alinernent with bolt 51 and the key is turned in one direction, say counterclockwise, hence shoulder 12 abuts the front face 18 of the transverse brace 53 and the front plate section is moved away from theY rear plate section. On the other liand,.to accommodate a smaller shoe, the bolt may be turned in an opposite direction. In this case, rear shoulder 14 of the bolt abuts rear facev 15 of brace 53 and upon rotation. of the `bolt front plate section moves relatively towards the rear plate section.

The strap anchoring device 59 is provided with spaced arms 18 each constituting a substantially rec'tangularly shaped lug 11 comprising a depending projection or shoulder 11. Extending forwardly and horizontally from front Wall 58 of the anchoring device is a fork generally desighated 18, deiining spaced tines or diverging lugs 18 forming means frictionally gripping the body of a flexible leather strap 88 threaded into a gap 8i dened by associated tines'l and depending lugs l1 of the anchoring device. If strap 88 is threaded in the anchoring device as illustrated in Fig. 5, the body of the strap 88is slightly compressed and irictionally bears against adjacent corners of an associated tine and lug and consequently transverse slippage of the strap is pre vented relative to the skate, and the spaced terminal shoulders 11 also cooperate to retain the strap in the anchoring device against displacement longitudinally of the body of the skate.

Although the anchoring device holds the strap against displacement, the latter may be quickly and manually removed therefrom by moving the strap manually and bodily forwardly to clear the spaced tines. and depending lugs 11. I

According to the invention provision has been made for eliminating the conventional rotatable transversely disposed bolt and its removable key utilized to actuate the transverse bolt in the matter of adjusting complementary jaws disposed at the forward part of they skate for clamping the fore portion of a shoe. In this connection, the herein disclosed skate has its front plate section li provided with diverging slots SI, each slidably guiding a cylindrical post 82 fastened to a horizontal arm 83 of a jaw generally designated 84 comprising an upstanding clamping lip 85 adapted to grip the fore part of a shoe mounted on the complementary plate sections II and I2.

Each slidably guided post 82 has rigidly secured thereto a collar or flange to prevent removal of its post from a respective guide slot 8I. The upper parts of posts 82 cooperate with the several openings or perfo-rations 81 in a nat vpivotally arranged locking plate or member broadly indicated 88. It will be observed that openings 8i in the locking plate form two rows of perforations diverging outwardly and in the closed posiu and the locking plate.

tion of locking plate 88 the diverging rows of perforations are in registration with adjacent diverging slots 8| in the front complementary plate section II.

Liftable locking plate 88 is pivotally associated with the front section 'II. For this purpose, locking plate 88 includes two depending spaced headed posts 89 extending through slightly enlarged openings 88 in the front plate section il. About each post 88 is encircled a helicoidal spring 8i cooperating with plate section II and a head 92 of a respective post to urge the latter downwardly relative to plate section Il, that is, to hold locking plate 88 substantially horizontally and adjacent plate section II, in other words, in a closed position.

The liftable locking plate 88 has its forward portion 93 overhanging the forward portion 94 of plate section II. Hence forward portion 88 may be conveniently manipulated or raised relative to plate section II as indicated by the dotted lines in Figs. 1 and ll. When lifted, spaced posts `89 .are elevated relative to plate section II and the rear marginal part 95 of the liftable plate 88 pivots on plate section II. Also perforations 81 formerly interlocking with the upper part of the slidable posts 82 are now free of locking plate 88. Hence' by grasping a jaw 88, the latter may be slidably moved relatively to plate section II, that is, its post 82 is guided along an associated biased or inclined slot 8l. In other words, when the locking plate is pivotally lifted or opened, the jaws may be moved inwardly or outwardly in respect to plate section Il and thereafter disposed in an adjusted set position and subsequently manual pressure is removed from the locking plate and the latter closes automatically due to the operation of springs 8i and in the closed position of the locking plate lcorresponding perforations 81 of the diverging rows of perforations receive and interlock with the upper partsof the slidable posts 82, hence preventing rectilinear movement of the spaced jaws 84.

Although jaws 84 are prevented from rectilinear displacement in the closed position of the locking plate, these jaws, however, are rotatably or swingably sustained relative to plate section I I This observation maybe made by considering Fig. l, showing the locking plate closed but since posts 82 are rotatably retained in openings 81, that is, displacementI of the jaws also causes rotation of their posts relative to diverging slots BI. Consequently, if a shoe 95 shown in dash and dotted lines in Fig. '1 be interposed between the spaced swingable 'clamps 84, the latter automatically conform to assume a position to grip the fore part of the shoe, provided, of course, the locking plate is closed.

Where it is desired to set the clamps to accommodate a different size of shoe, the operator simply lifts or opens the locking plate and slidably moves the clamps to the required new position after which the locking plate is manually released, thereby closing automatically.

As illustrated in Fig. 7, strap 88 has each of its ends provided with a buckle 86 adapted to interlock with alternate free ends 91 of a flexible leather strap 98' threaded through appropriately slotted spaced heel guards 98 projecting upwardly from the rear plate section i2.

According to the preferred embodiments of the invention illustrated in Figs. 11-15 inclusive, the skate construction is substantially identical to the form hereinbefore disclosed in detail in connection with Figs. 1-10 inclusive except in the means for swingably supporting a truck and the means associated with the truck to preclude lateral displacement of the removal stub shafts. In this connection, it will be noted, that in Figs. 11- 15 inclusive, yoke I`| of a truck is swingably sustained on a fulcrum pin I| having an annular shoulder H32 cooperating with an upstanding lug Il to prevent longitudinal displacement of pin MI in one direction and with a cotter pin key I appropriately inserted at the rear or a reduced portion I ll of the fulcrum pin to prevent longitudinal displacement of the latter in another longitudinal direction.

Swingably associated with block |65 secured to yoke Il' is an irregularly shaped one piece loop or clip |95 comprising spaced arms IO'I having intermediate portions thereof arcuately depressed to denne arches |08 adapted to be arranged in the spaced slotsV I9 of an associated knuckle I8 and in the spaced grooves 25 of a pair of alined stub shafts interlocking with the latter to prevent lateral displacement thereof. Io removably retain such relation, however, lip |09 of the loop cooperates with a depending tongue ||I3 oi a winged catch I|I rotatably mounted on the fulcrum pin IIU, catch III being normally urged against an adjacent depending lug I4 of its channel |3 by a helicoidal spring |I2 encircling an overhanging headed part of the fulcrum pin IIJI.

In Figs. l1 and 12 the rear swingable loop is shown open and the front loop is interlocked and retained interlocked. In an open position, tongue HE? of the catch is raised. In a closed position, lip |09 of a loop is interlocked with an associated tongue I I and the latter is straddled by the spaced arms |01 of the loop (see Fig. 12). In such relation, tongue I I0 is in a lowered position and additionally supports lip portion |09 of the loop.

Where it is desired to assemble a pair of alined shafts in its bearing, catch III is manually grasped by its diverging wings II3 and bodily moved against the resistance of its companion spring H2 and rotated to arrange its locking tongue I|Il out of alinement with intermediate ear 2| and the pivoted loop is swung out of the bearing. The stub shafts 23 carrying wheels Eil are then inserted into the bearing. When bosses 2S strike the end faces of the bearing, slots 25 of the stub shafts register with spaced slots I9 thereof. Subsequently loop |05 is swung as to dispose its spaced arched portions |98 within grooves 25. The winged catch ||I is then rotated to dispose its interlocking tongue between the terminal of the loop and underneath lip its thereof as shown, for example, in Fig. 14. Hence the loop is removably interlockedwith tongue IIE) of the catch. The action of spring Iii? automatically holds rotatable catch |II against an adjacent lug I4 until manually retracted. It follows therefore that a rotatable catch is retained in an interlocked relation with an associated swingable loop until manually retracted and rotated. To remove a wheel or Wheels, the above mentioned steps in the matter of assembling the Wheels to its truck, are reversed. In other aspects, both from the standpoint of function and structure, the embodiment illustrated in Figs. 11-15 is substantially identical to the form earlier disclosed in connection with Figs. 1-10.

The present application is a division of applicants copending application S. N. 40,579, filed September 14,1935,
