12 Claims.

This-structure relates to a handle clamping structure.

The chief object of this invention is to provide a, clamping band arrangement, or the like, with a handle, the band portion being arranged for movement into a contracted position for the clamping of an object therein and being releasable for releasing such object from such clamp ing engagement.

Another chief object of the invention is to provide such a band arrangement with a handle that may be readily from the band.

type band i attached to and detached A further object of the invention is to provide means for quickly and easily moving the band from the released to the clamping position and vice versa, which means is permanently associated with a portion of :the band so as to be comparatively inseparably mounted thereon but which is detachably associated with the-handle so that the handle may be readily associated with and detached from said band.

Thechief feature of the invention consists in the construction of the handle band whereby the aforesaid objects of the invention are accomplished and whereby in addition the strain on the handle and band connection is so applied that increasing strain effectsincreasing rigidity of association between the band and the handle. Otherobjects and featuresof the invention will be set forth more fully hereinafter.

Thefull nature of the inventionwill be more fully understood from the accompanying drawings and the following description and claims:

In the drawings, l l l 1 i it i Fig. 1 is aperspective view of a handle band suitable for the purposes set forth, the "handle Fig. 3 is a perspective view of one embodiment of the pistol grip type handleillustrating in detail the connecting portions thereof. j e

Fig. '7 is a perspective View of a metallic con for purposes set forth hereinafter. M

Fig. ,8 is a perspective view of a diamond-like opening in theband end adapted for headpassageand retention; 1

Figs. '9 and 10 are perspective views of moditactmember carried by the clamping structure .fied forms of handles.

In the drawings, l0 indicates a band, herein shown substantially circular in outline and the band has twosimilarly directed ends H, and I2. Each of these ends I! and 12 are shown provided with a curved formation, indicated at Ilia, and Ma, respectively, in cross section, and the edges thereof are turned inwardly for reenforcement purposes, andthe like, as at lib and F22), respectively, see Fig. 2: i

The curved formation lla and 12a insures rigidity in the'enol. In other words, it constitutes astifiening formation. Thetwo beads on each end in conjunction with the intermediate portion Iforma pair of spaced tongues, as it were, and a groove intermediate the same. The particular special function of the latter will be, set forth more fullyhereinafter.

Theend H is provided with an opening [3 and extending longitudinally of the end I I and from opposite sides of said opening arethe oppositely directed slot or wing extensions; The portions l4 and central portion l3 form a slot through the end H which may bebroadly said tobe of bayonet or keyhole typein that a headed member may be readily passed longitudinally through the aforesaid opening or slot, and then turned so that the head portionwill bear on the external surface thereby. l i i The other end l2 of the band is apertured as at I5 and rotatable and slidable longitudinally of the end and be retained therein is an enlogated member [6, the same having atwisted portion Ii intermediate its ends and a head 18 similar'to the flukesof an, anchor.

The flu'kes pass through the portions M of the bayonet slot and when the membenlfi is turned,

for example at 90, these flukes bearupon the pair of ears 22 and the enlarged heads 20. bear on the outer faces of said ears. These ears have a cam formation or face 23 and these two ears are joined together as at 24 and the same are extended and terminate in a finger engageable portion 25. There is also provided, if, as and when desired, a hardened washer 26 slotted as at 21 and the same is slidably mounted on the member 16 and bears on the exterior or remote face of the end I2. Preferably slot 21 prevents washe er rotation on portion 2|.

Whenever the slot or opening in end I2 is of the character illustrated as provided in end II, it will be obvious that the entire unit, that is, cam clamp and elongated member, may be completely detached from and detachably attached to the band and from either side or end. No illustration of this embodiment is believed necessary. Preferably the connection aforesaid is not of completely'separable type.

From the foregoing, therefore, since the preferred opening I is of less diameter than the head [8 and since the cam ears are permanently, although pivotally united to the opposite end of the member l6, these connected members including the bearing member 26 are all permanently connected to the band.

The numeral30 indicates thegrip portion of a pistol grip handle having the angular extension 3|. This angular extension Si in plan may be said to be wedge or keystone shaped, that is, its outer end 32 is wider than the innermost portion indicated by the numeral 33. Herein the two side faces 34 each are shown provided with a groove that is comparatively deeper, as at 36, at each side than the central portion 31 of said groove. Thus this formation is substantially complementary to the formation of the band end that is seated in this groove. The resulting stock at its forward end is thus of keystone or wedge shaped, see the immediate left hand portion of Fi 3.

Extending from the front face 38 or forward end of the handle and rearwardly, is an elongated notch or slot 39 and this extends from one groove to the other and has a length approximately one-half that of the length of the groove, as shown more fully in Figs. 3 and 4.

Whenever it is desired to mount the band upon the handle, the end [2 is seated in the corresponding groove in the handle. The elongated member [6 then is seated in the slot 39 thereof; the other end l'i then is brought into contact with the opposite side of the handle and seats in the corresponding groove. Then the elongated memher is passed through that end II, as aforesaid,

and the member is turned at 90 to anchor the member to the end i I. When thus anchored the finger piece 25 is engaged and the cam member is tilted until said finger piece lies adjacent the band, as shown in Fig. 1. Whereupon, the band is'rigidly connected to the pistol grip handle. This is the vessel clamping position.

Another method of mounting the band is with the finger grip piece extending substantially parallel to the end l2 and with the head I8 bearing on the exterior of member ll, the two ends H and I2 thus forming a channel that can receive the handle grooved end portion 33 if presented between the termini of said ends. Then when these termini following such presentation engage the shoulders 40 of the handle, it will be apparent that the member I6 is fully seated in the elongated slot or notch 39. Then when the finger grip piece 25 is tilted from the position parallel to the end 12 to a position immediately parallel to the band, the handle will be locked rigidly to the band in vessel clamping position.

Upon comparison of Figs. 2 and 3, it will be noted that the handle 39, when detached, may be nested within the band it, Whether the ends be connected or detached and hence, be shipped flat or knockdown in a minimum volume container.

It will be observed that relative up and down movement of the band is prevented because the beaded portions of the ends seat in the portions 35 of the handle. It will also be apparent that any attempt of the handle to pull away from and separate from the hand, because of the fact that the member it is seated in an .open ended slot, is resisted for the same is prevented by reason of the wedge or keystone formation shown most clearly in Fig. 4, although it is also illustrated but in perspective in Fig. 3. Any tendency of the band to twist or rotate about the handle is also resisted because the member l6 cannot turn in a direction corresponding to end for end movement.

The handle cannot rock up and down because of the elongated character of the tongue and groove connection. Further, the complementary curved ends clamp the handle stock therebetween in such a manner that rocking as aforesaid also is prevented. As stated, the wedge formation causes drawing of the ends and included stock together in tighter relation under increased strains.

It will be quite obvious that other forms or readily disconnectible head and slot constructions may be substituted as shown in Fig. 8 for that herein specifically disclosed in Figs. 1 and 2 and indicated by i8, i3 and i4 therein, and that the bearing plate or washer 25 thereof may be utilized or omitted, if desired, and that the reentrant character indicated by 36 in Fig. 3 of the handle groove may be modified or omitted as in Figs. 9 and 10.

In Fig. 8 the band 31 With end 3 has beaded inturned edges 3| ib. The hole 3l3, however, is broadly diamond shape being elongated longitudinally of the end. The vertices are rounded as at 314 with the side faces flat as at 3l3a. Functionally, this slot is the same as that shown in Fig. 2.

It also will be understood that the pistol grip representation Of the handle is purely conventional and any other desired type of handl having singular connection to the clamping band or like structure may be utilized as shown in Figs. 9 and 10.

Whenever it is not desired to mount the handle upon the band structure as secondarily described, hereinbefore, there may be provided, see Figs. 9 and 10, a hole 43!] and 539 respectively of sufficient size in lieu of the slot 39 and in that event the handle is mounted on the clamping band or like structure only by passing the enlarged head I8 and the member l6 through this ,opening prior to passage through what has been broadly termed the bayonet slot type opening in the end H.

Furthermore, it will be noted that the head 18 on its fluke portions has an end contacting face conforming in curvature to the curvature of said end. The purpose efthis curvature is duction of a handle a'svaeev that when the clamping finger piece 25 is positioned immediately adjacent the band for clampingxassociation, it is substantially incapable of any other than the pivotal movement described-- The handle preferably is of heat insulating material. This may be of wood, composition,

plastic or glass. In this connection it is to beobserved thatit is comparatively easy to drill and form by routing, and the like, the variou slots,

seats, grooves, et cetera, in the handle. when it is of wood. When it is of molded plastic, et cetera, the material may be readily molded. How ever, whenthe materialis of glass it is to be understood that the sam may be drilled butis attended by great difficulty and considerable breakage. Accordingly the slot that receives the member 16 when formed as a slot permits proe of glas or. one that requires no drilling.

When the invention is applied to glass containers, such as percolators, drip-o-lators, suc- ,faceof the metal band is highlyapolished. If

. Preferably the interior or vessel contacting surdesired, it may be plated. The purpose thereof is to reflect from the band as much heat as Poscompression, the remainder being under tension, 4

ashock or ijar. Prevention of scratching by the 1 handle, if of glass, and more particularly thevessibleand back intothe vessel, if subjected to heat. a It will also be noted that th structures illustrated in each of Figs. 1 to 5, inclusive, each in.- clude another member; Glass to glass contact is ofabrasive character. Glass molded articles primarily having a surface forming skin under high etc. In glasscooking ware, this relationship is extremely critical- Any material weakening of i the skin may, upon slightshock or jar, result in complete shattering of the article that ordinarily would not normallyshatter or crack under such sel if of glass, is most desirable.

The additional member referred to prevents such'scratching and also provides a reenforcing or stiffening bearing member. :It is illustrated in Fig. 7 and of a form to accommodatethe handl 3D withitsdepending projection 34. 1

of the end and band upon initial application thereof to such an oversize container and handle and thus takes a proper permanent setslightly different from the original unparted set. Such set is thereafter retained. The foregoing accommodation is permitted because the force required to bend the stock for such set is less than that required to crush the container.

As a result each handled bandis initially in-'.

dividualized to its particular container and rigidly j holds and clamps sameinthe band regardless of accepted tolerance variation in containers.

Reference will now be had to Fig. 5. Therein primary numerals indicate like parts and similar numerals increased by one hundred indicate sim ilar parts. This form of the invention is the reverse ofthat shown in Fig. 4-in thattheband and handle are rigidly connected together when finger. piece I lies adjacent the handle portion and are releasable or detachable when piece I25 An elongated metal strap has an intermediate portion arranged in tube formationgproviding a bore 5| therethrough. The two adjacent portions 52 abut each other .andinclude oppositely directed lateral. extensions 53wwhich terminate in parallel portions 54, each of which has a projection 55 laterally thereof and substantially parallel to portions 53. One and the upper end includes. rearwardly directed tongue i 56. The lower and other end includes the groove forming portion 51. a a

As shown in the several figures, this contact element is mounted onmember [6-20, which projects through tubularity. 5|.

vents separation. Portions 55 bear against the Head 1 5 prevessel while tongue 56-overlies the upper face of handle portion 33. Groove portion 51 underlies handle: portion 34.

Thus handle-vessel contact is prevented and scratching is eliminated. Elimination thereof.

prevents glass vessel skin rupture. with subsequent fracture, etc., as previously. set forth,

In Fig. 6 is illustrated a further embodiment of the basic invention. Herein numerals of the primary. series indicate like parts and "numerals of the two hundred series indicate equivalent parts. Each end isprovided with a fiatbearing areaas at 2lla and 212a. Herein a male screw 221 has its head 12m bearing on area ll2a. A

female socketscrew2l6 having head 218 bearing on area 2| la hasthreaded connection at 211 with screw!!! These two areas are so embossed that used inits broad sense, to-wit an element for.

The interconnected screwsseatin notch 39' of handle 30 and s'erve to draw ends 2| I and 2 2 into clamping engagementwith the portion 30 of the handle when the ends are laterally applied thereto, see Method I aforesaid. These screws may be separated, or merely unthreaded the desired amount to longitudinally apply the handle to the band as previously described in Method II aforesaid. In both modifications, when desired, as previously described, the slot39 may be used, but for Method Ithe slot35 may be formed as a hole.

Preferably the glass or vessel contacting face of the member illustrated in Fig. 7 may be brightly polished and plated .as well. i i i Although this member is not shown applied to the handle shown in Fig. 6, itis quite obvious.

it can be applied thereto. Note that portions 54,, 53, 52 and 50 allseat or nest inthe notch, or, slot :in the vessel supporting end of thehandle member 30. The term band herein and in the claims is encompassing an article such as a vessel and substantially conforming to the outline thereof so encompassed. e

Fig. 9 is a perspective view of a modified form of handle having the hand clamp portion 430 in longitudinal alignment with the anchoring portion of the handle. Herein in lieu of the notch 39 there is provided a circular opening 439, and herein in lieu of thereentrant character of the side face recess of the anchoring portion of the handle the reentrant portion being indicated by 36 inFig. 3, this isfomitted and the r recess may be of plain face or rectangular character. a

- Fig. 10 is a view similar to Fig. 9 but herein the l handle portion 530 is shown of slight arch type as .distihguishedfrom a straight .handle, see Fig.

l 9, one pistol grip handle, see Figs.-1 and 3. In

this form of the invention the hole 539 is elliptical in cross-sectional outline as'distinguished from the circular opening shown in Fig. 9. Such an opening accordingly requires a major axis but slightly larger than the overall length of the head 13 and a minor axis, but slightly. greater than the width of the portion 2|, see'Fig. 2. From the aforesaid therefore it is clear thatltlie broader features of the invention with open notch 39 is not a necessity eitherfor the connection shown more particularly in Figs. 1, 4 and 5, or for the connection shown in Fig. 6, or equivalent connections well-known in this art. Also, for the broader features of the invention, the actual direction, an ornamental outline and configurations of the respective handle portions, designated by the numerals 30 and N30 wherein N is the appropriate digit in the'hundred position, in the several handles illustrated, is va'riable at will or as desired.
