Assembling Machines, of which the followingis a specification.

K My invention relates to machines for form ing and assembling the parts of fastening.

devices of the class commonly employed as glove: and garment fasteners and for analogous uses.

Heretofore machines have been constructvices of the character indicated, said machines comprising a plurality of verticallyarranged cam-operated plungers carrylng (hes, 1n combmatlon with means forautomaticallyfeeding a strip of metal to the first plunger and means for automatically transferring the blank cut by the initial plunger successively to the remaining plungers and discharging the blank after it has been operated upon by the last of the plungerdies.

The primary object of the present invention is to greatly increase the capacity of machines" of. this type by utilizing both. strokes of the reciprocatingslide, which car- The machine illustrated in the accompany-- ing drawings is designed for the manufacture of fasteners each consisting of three se arate parts, twoof which parts are formed y the machine, while the third part or element is fed to the assembling mechanism, where. it is automatically assembled with the other. two elements, all of said elements being then permanently compressed together to form the completed product. be understood that the invention is not restrictedto the production of this particular species of fasteners, but is of such scope as to embrace and include the production of all such fasteners as the construction of the machine adapts it for producing, and the threepart fastener above referred: to' is here de .feeding the metal strip to the plungers.

It will however,

scribed and shown for convenience of de scription, and so illustrating one of the specific functions of the improved machine.

Generally stated, the machine comprises a plurality of plungers supported in vertical guides at the front of the machine, a horizontally reciprocating slide arranged below the plungers, .two series of oppositel -disposed spring-fingers for grasping the f: and transferring it to the next ad acent plunger, means for feeding a strip of metal to the lank initial plunger of each series, and assembling mechanism consisting of a horizontallysup ported circular table provided with seats orpockets to receive the blanks as they are delivered from the plungers, means for imparting the required rotary motion to the assembling-table, and means for permitting the feed to the assemblin mechanism of the third part or element of t e fastener.

In'the drawings, Figure 1 is a front eleva tion of a machine embodying the invention, parts being omitted and broken away for the. sake of clearness of illustration. Fig. 2 is a view, partly in elevation and partly in vertical section, the assembling-table being shown in central vertical section. Fig. 3 is a top lan of the machine, parts being shown in horizontal section and the plun ers being Fig. 4 is 'a' rear elevation, partly in section, showing the mechanism for operating the assembling-table. Fig. 5 is a plan view of the assembling-table, partly, broken" away. Fig. 6 is a detail plan, partly'in section,.of the feed device of the assembling. mechanism- Fig. 7 is an elevation of a pair of rollers for Fig.

omitted to afford 'a' clear view-o the bedplate slide and parts associated therewith:

8 is a section on the line wa ofFig; 3,- and Fig. 9 is a section on theline-y y of-Fig. The reference-numeral 1 designates a stand.

or bench upon which the machine is supported, and .2 a casting secured to the: table 1 and serving as the supporting-frame for the mechanism. The frame 2: is provided with bearings 3, within which is mounted a shaft 4.. At either side of the longitudinal center of. the

shaft 4. within. the frame is fixed 'a series of alinement with two series of lungers 7 and 8,.

supported inbeari-ngsin. t e frame-.2 and adapted to be struck .by thecams at each revolution of the shaft 4. This contact of the cams with the upper ends of the plungers effects the downward movement of the plungers, and the reverse or upward movement of said plungers is effected by the contact of the cams 5 and 6 with arms "9, projecting forward from a series of guide-rods 10, supported in suitable bearings of the frame 2. (See Fig. 2.) Each of the guide-rods 10 is connected to one of the plungers by an arm 11.

- To the lower end of each of the plungers is attached a suitable die, said dies being adapted .to act upon blanks carried by a reciprocating slide 12, su ported upon a horizontal die-bed 13 below t e plunger.

14 and 15 designate reels supported at the front of the machine upon shafts 16 and 17. Upon each of these reels is wound a strip of sheet metal, (dotted lines, Fig. 3,) the free end of each strip being carried rearward under a perforated guide-plate 18 and between feedrollers18 to a winding-reel 19, located at the rear of the machine, as shown in Fig. 7. The feed-rolls 18 are arranged in pairs within a suitable frame and are geared together. Upon the shaft of thelower roller is any suitable brake device 19' to prevent backlash. The shafts of the lower rollers 18 are operated by .rod connection 18 with the shaft 58 through any suitable connections, such as pawl-and-ratchet mechanism. (Shown in Fig. 8.) These guide-plates 18 are so located with relation to the plungers that the outermost plunger of each series is in exact alinement with the perforation in the adjacent plate to adapt it topass therethrough and punch out a blank from the metal strip. The receiving or winding reels 19 are mounted upon shafts 20, each driven by a. pulley 21, connected by a belt 22 with a shaft 23, supported inbearings 24 of the frame below the die-bed 13.

The die-bed 13 isformed with a series of openings 25, serving as female .dies and corresponding in number to the plungers. Within each of the openings 25 is arranged an ejecting-pin 26, adapted to be operated by a series of cams 27 on. the shaft 23, as best seen in Fig. 1 of the drawings.

Upon one end of.the shaft 4 is mounted a clutch-pulley 28, adapted to be connected by a driving-belt with any source of power. Upon the opposite end. of the shaft 4 is mounted a bevel-gear 29, meshing with a corresponding gear 30, fixed to the upper end of a crank shaft 31, supported in bearings .formed in projecting parallel arms 32 and 33 of the frame. Uponthe lower end of the crank-shaft 31 is mounted a bevel-gear 34, meshing with a .bevelegear 35 on the end of the shaft 23, and thus serving to drive said shaft from the shaft'4. a.

The reciprocationiof the slide 12 upon the die-bed 13 is effected by means of a pitman 36, connecting the outer end of the slide with I the crank 37 of the crank-shaft 31, the inner end of said pitman having an elongated slot 38 to receive a pin 39, projecting from the slide, and thus provide a loose connection between the slide and the pitman.

Upon the slide 12 are arranged two series of spring-fingers 40 and 41, said fingers being arranged in pairs and pivotally secured at one end, a spring 42 being interposed behind the fingers of each pair. The function of these spring-fingers is to grasp the blank and. hold it in position to be operated upon by the next plunger-die as the blank is carried along by the movement of the slide.

It will be noted that the two series of pairs of spring-fin ers are oppositely disposed, the result of sudh arrangement being that each series of fingers carries the blanks toward the center of the machine in position to be delivered to the assembling-table, and this peculiar arrangement of the fingers insures a delivery of blanks to the assembling-table at each stroke or movement of the reciprocating slide. In other words, upon the inward movement of the slide the pairs of fingers 40 will deliver blanks to the assembling-table, while upon the outward movement of the slide the fingers 41 will deliver blanks.

Referring now to the mechanism for as sembling the different parts of the fastener, I employ a revoluble table consisting, as clearly shown in Fig. 5, of three concentric disks 43, 44, and 45. The upper disk 43 is formed near its periphery with equidistant openings or pockets 46. The intermediate disk 44 is formed with peripheral ratchetteeth 47, and the under disk 45 is provided with equidistant peripheral notches 48. The table is centrally mounted upon a stud 49 and revolubly secured thereon by a nut 50 and washer-plate 51. The revolution of the table is effected by means of a lever 52, fulcrumed at the rear of the frame 2, a link 53, pivotally secured to the lower end of the lever 52, and a slide 54, moving in a guideway of the frame, and a pawl 55, projecting from the slide 54. The upper end of the lever 52 is provided with a pin which projects into the slot 56 of a barrel-cam 57, mounted upon a shaft 58, supported in bearings of the frame. The pawl engages successively the ratchetteeth of the central disk 44 of the table, and thus the required intermittent rotary movement of the table is insured. A locking device is provided at the front of the machine to lock the assembling-table while the latter is at rest. This device comprises a slide 59, supported in a guide-block 60, and a lever 61, connected to the slide 59 and adapted to be struck by a cam 62 on the shaft 23. The rear end of the slide 59 is reduced to form a tooth 63, adapted to engage the notches in the lower disk 45 of the table and lock the table against movement until the slide is Withdrawn. Referring now particularly to Fig. 4 of the drawings, 64 designates a vertically-movable slide supported in bearings of the frame and adapted to be operated by a cam 65 on the shaft 58.v The lower end of the slide '64 carries a tool 66 for uniting the parts of the fastener. A slide 67, also supported in bearings of the frame, carries tools 68, which perform the finishing stepin the assembling of the parts of the fastener.

69 designates a hopper or feed-boX, within which the third part or element of the fastener is fed through a slotted tube 7 0m the assembling-table. This tube is inclined, as shown, so that the eyelet (or other part of the fastener) is fed by gravity through the tube until its movement is arrested by a spring-pressed pin 71, Fig. 6. The eyelet is released by a finger 72, secured to a stud on a slide 73, operated by a lever 74, actuated'by a cam 75 on the shaft 58.

76 designates a spring-encircled stud supported in a guideway below the point where the final step in the joining of the parts of the fastener occurs. This stud is actuated by a lever 77, operated by a cam on the shaft 23 to elevate the die-pin 78 and effect the required upsetting operation. The completed fastener is then pushed up tothe surface of the upper disk of the .table by a raiser and scraped off into a discharge-opening 79 by means of a stationary stripper-plate 80.

At the lower end of the tube are two cooperating pivoted fingers 81, formed with seats 82 to embrace the eyelet and connected by a spring 83.

The general operation of the mechanism has been disclosed in the foregoing description of its construction; but the detail. operati'on may be briefly eX lained, as follows: Two strips of sheet meta are fed to the machine simultaneously, passing from the front reels 14 and 15 under the perforated guideplates 18 and thence between the feed-rolls .18 to, the rear winding-reels 19. The first plunger 8 punches a blank from one of the strips, and this blank is then carried by the first pair of fingers 40 to the next plunger 8, and so on until each of the four plungers 8 has acted on it. The function of the last plunger is to force the blank into an adjacent pocket in the assembling-table, which extends below the bed-plate slide.- On the reverseor right-hand movement of the slide the plungers 7 operate upon the other metal strip. Referring to Fig. 3 of the drawings, one blank is first punched at the point a. It is next operated upon at the point I) and again at the point 0. At the point (1 it is forced into one of the pockets of the assem-. bling-table. It should be hereuexplained that while the punches 8 are operating upon the stripof metal to form one part of the fastener the punches 7 are at rest, the cams being so disposed as to insure this result, and when the plungers; 8 are raised the plungers 'Z operate upon their metal strip to form an other part ofthe fastener, which part when formed is delivered at the point e on the table. The movement of the table then continues until the point f is reached, where thethird. part of the fastener is forced down upon the other two by the tool 66. The continued movement of the table brings the united parts under the tools 6.8 at the points g. The arrangement and timing of the cams are such that the bed-plate slide moves to the left for a time corresponding to ninety deincluded within the scope and terms of the appended claims, it being my especial purpose to cover, broadly, the association and combination in a single organized. machine of means for forming the parts of a composite fastener and means for assembling such parts into a finished product.
