SETTING-MACHINE.

Specification of Letters Patent.

latented Dec. 2, 1913.

Application filed July 25, 1911. Serial No. GlOA-BS.

To all whom it may concern:

. Be it known that I, Eowin BALL STIMP- son, a citizen of the lnited States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Setting- Maehines, of which the following is a specifiation.

My present invention relates to a settingmachine including a machine for simultaneously setting a plurality of fastening devices, the particular machine shown being adapted to set eyelets, but by appropriate modifications obvious to those skilled in the art the same machine can be made to simultaneously set aplurality of snapfasteners and the same applies to other fas- .plunger is down.

tening devices.

In the drawings which as stated show one specific form of machine within my inventiom Figure l is a side elevation of a. machine which sets a pair of eyelets si multaneously; Fig. 2 is an enlarged elevation of the reverse side of the upper or body portion of the machine of Fig. 1; Fig. 3 is a 'tront view of the head looked at from the left in Fig. 2, the plunger being up; Fig. lis the same view with'the parts shown in the positions occupied when the I will now describe the devices of the drawings, reserving it to the claims to point out thenovel features and to'dctine the scope of the invention,- it being understood that the claims will be given due range of equivalents.

l is the base of the machine. 2 the pillar, and 3 the body supported on said pillar. said body having a horizontally extending arm l and a horizontally extending head 5 which overhangs said arm. The head is provided with a pair or'. vertically extending sockets located side by side. One socket is rectangular iu eross-scction and in it slides the plunger 6. in the other socket slides a stem 7 carrying the presser-toot 8. Sup-- ported on the lower end of the plunger (3 is a cross-piece 9 from which in turn depend a pair of driving stems 10. each having the usual telescoping tein ll. adapted when pressed to telescope ul'iwardly into its driv ing stem 10 but normally heing held yielding-1y extended as shown by a coiled spring (not shown) located between it and the driving stem. The resser-foot 8 has a pair of vertical openings through it, alined with the respective driving stems 10 and sufficiently large to receive said stems freely through them. The pressehfoot support ing stem 7 is of course splined or otherwise adapted to its socket to prevent it from rotating therein.

lidesignates a pair of piercing points supported from a block 13 on arm 4t and extending vertically upward in alinement. with the openings in the presser-foot and with the stems l1.

14- is a long horizontally extending arm, pivoted at 15 to the body of the machine a. good distance from the piercing-points 12 and there having openings through it for the passage of said points. 7

16 is a eompressionspring between the block 13 and arm 14 which keeps the latter yieldingly upheld.

'17 is a headed pin passed through an opening in the arm 14 into the block 13 and whose head acts as .a stop limiting the up ward movement of the arm 14 impelled by the spring 16. During the operation of the machine, the work is supported on this arm H. the presser-toot then descends forcing the piercing points through the material and gripping it firmly preparatory to the descent of the driving stems to set the eyelets inthe holes in the material formed by the piercing points.

The plunger 6 is reciproeated vertically by means of a foot. lever acting on togglearms. Thus 18 designates said toggle-arms; the lower of which is pivotallyconnected to the plunger 6 by a pin 10 passing through the slotted, upper end of the plunqer'within which the toggle arm works. The upper toggle arm has an enlargement at its free end from which project t-rnnnions that extend with hearing fit through the arms 5 of a fork in the head 5 of the machine. Upon the free ends of these trunnions are fixedly scoured crank- arms 20 and 21 respectively for purposes soon to be described.

22 is a bell crank lever tulcriuned at 23 (Fig. ii to the hack oi the head of the. machine. its upper arm being connected by a,

link 24 with the knuckle of the toggle and l side of the machine head 5 acts as a stop its lower arm being connected by a link 25 with the rear end of a foot lever 26 pivoted at 27 to the pillar. The result is that when the foot is applied to the forward end of the lever 26 to press it down, it results in straightening the toggle to lower the plunger (5. On the other hand, releasing the footlever relaxes the toggle and elevates the plunger by reason of the lifting action of the spiral spring 28 connecting the foot. lever with the pillar of the machine.

The above is the means for reciprocating the plunger (3, and driving stems. I will now describe the same for the presser-itoot stem 7:---29 is' a. horizontal link pivoted at one end 30 to the machine-head and at the other 31 to the presser-t'oot stem. 32 is a vertical link connecting said horizontal link 29 at 33 with the crank-arm :20. In this arrangen'ient. the arms 20 and 32, (Fig. l) constitute a pair of toggle-arms which straighten (on the partial down-pressing ot' the foot lever 26) before the main togglearms 18 straighten, with the result that the prcsscr foot; 5 is forced into its down position to drivethe piercing points12 through the material before the plunger (3 is fully carried into its down position. However,

upon the complel ion of the down stroke ol the footlever 26, the main toggle-arms 18 also become straightened and thereby force the plunger 6 and the driving stems l0 and 11 into their fully down position to the eyelets (which theyhave meanwhile picked up from th roadway) into the material.

Describin now the eyelet delivery parts and their OIl(3ltllll()Ii3-'lis the box of a magazine whose base is a plate 35 supporting a pair of roadways {it}. which converge from opposite sides of the magazine .toward the delivery ends of the roadways.

37 is a rearward hollow extension from the upper back portion of the platc lo thereby forming a hopper l'or loading lhennigazine with .(.=yclcls through the open mouth ot' the said hopper. the cover of which is desig- A'rear extension from the hopper is supported between a pair of vertical lll 4!. connecting the roadways. -42 is a siini lai' brace above. having a bolt l threaded therethrough, which by contacting with the 5" to hinge about a horizontat axis.

which can be adjusted to stop the motion of the roadways (under the described action of gravity and the spring 2-30) at the point at; which the eyelets in their delivery-ends are in the exact path of the stems 11, so that the latter in their descent thread through said eyelets and pick them out of the road 'ays. lock nut 4.4 secures the stop bolt 43 in its proper stopping position of adjustment. After the stems 11 have. entered the eyelets as aforesaid, the following canimeans automatically carries the roadways outwardly from their position in Fig. 3 to their position in Fig. l: is a roller mounted in central position on the rear side of the brace -ll (Fig. Ll) between the roadways. It rolls in a. vertical cam-groove in the side of the plunger 6, the bottom of said groove having the contour indicated by the dotted line 46 in Fig. 4. so that as the plunger descends beyond the point where the stems 11 have entered the eyelets the roller and the roadways are forced gradually outwardly-the etlccts of which are lirst to disengage the end-eyelets from the roadways and permit; them to be carried (low!) on the stems l1; and seeond:--to put the roadways in a position whichdoes not interfere with the reciprocation of the plunger, in which position the roadways are temporarily locked until automatically released as follows :-'l7 is a pin projecting from the side of the brace 4L connecting theroad 'ays. 48 is an elbow-shaped latch pivoted at t! to the machine head. The lower edge of the horizontal arm of this latch is notched to receive and interlock with the pin 47 and retain the roadways in the outer position into which they are carried by the described coaclion of the plun- I A spring 50 connects the elbow-shaped latch with the 'lOO head of the machine to carry the latch yicldingly into its describcll locking position until. released as tollows:---;\tier the plunger (3 has completed its do'wnstroli'e and the setting stems 10 and 11 have set their eyelets in the material. and utter said parts have reached a point on their up stroke where they are above and llltl'tl til't clear of the ends of th roadway. then a pin fil projecting rearwaiwlly from the plunger (3 strikes the horizontal arm ot the latch 43 during the continued lip-stroke ot' the parts, and discngages the notch of said latch from the roadway pin 47 as shown in Fig. 1-1. so that the roadway then autoiinitically re turns to its aliiied position. preparatory to delivering another pair of eyelets to 'the F'ltlilF ll upon the nextdown stroke of the plunger.

The magazine box 3-1 which is of. the prelerred constructionwith internal grooves,

fee

etc, shown in my copending application, Serial No. 624173, coiiperates as usual within circular flanges on its base-plate 35, part of which 52 (Fig. 2) is fixed and permanent and parts of which 53 and. 53 on either side are removable or pivotableout of the way as shown at the right in Fig. 2, to uncover the channels in the roadways where they meet with the delivery openings from the magazine box and so relieve any jam at these points. Latches 54 and 54 retain the pivotable flanges in working position. The eyelets by a rotary oscillation of the magazine box 34 are fed therefrom into the channels of both roadways 36. The direct and return rotary oscillations of said box occur simultaneously with the up and down strokes of the plunger 6. Thus 55 (Figs. 2 and 4) is a link connecting crank arm 21 with a crank arm 56 fixed on 'a pin 57 rotatably supported in a bearing through the plate 35. The outer end of this pin extends hrough the sleeve of the box 34 and beyond the topof said box is squared or flattened on the side to fit a correspondingly shaped opening through the center of a spring 58 having radiating spring arms 58 and wing-nut 59 on the reducedthreaded end 57" of this same in, keeps the spring member 58 thereon. The top of the box 84 has radial grooves 34L (Fig. 2) so that the spring arms normally lie in these grooves. Thus the box normally partakes of the same rotary oscillation as the spring arms 58, which in turn are carried by the pin or rock shaft 57, the latter inturn bein rocked by its crank 56 driven by link 55 rom the crank 21. Should however a jam occur of the eyelets in the box 34:, then the spring arms 58 will ride up out of their grooves and slip idly over the top of said box. Whereas the magazine box in the ordinary machine has an intermittent rotary movement always in the same direction, it is to be noted in the machine shown that the box oscillates, the eyelets being delivered at each oscillation to one-or the other roadway alternately.
