Beverly, in the county ol Essex and (lom-4 monwealth of Massuchusetts, have invented certain lm rovexnents in Eyeleting-illn chinos, of w lich the following description, in connection with the accompanying drowings, is n specification, like reference eharacters on the drawings indicating like ports in the several figures.

his invention relates to machines lor setting eyelets endv erticularly to machines having u combine punching and setting device.

Prior to this invention the o eretions incident to the setting of eyelets leve usually' been performed either bj two seperate machines, one for punching holes inthe stock and the other for setting the eyelets in the punched holes, or by e single machine in which separate mechanisms were provided for the punching and setting operations. Although machines have been devised prior to this invention which it was intended should unch the hole in the stock und set the eye et at one stroke and without the necessity for moving the stock from the punching device to the setting device, so far as l am aware these have not proved to be entirely satisfactory, especially in setting eyelets in thin stock such as palper.

A11 object of this invention t 'ierel'ore is tov provide a, machine 1n which the punchingr and setting devices are so'combinod that n single progressive movement ol' the open-itH ing mechanism both punches n hole in the stock and sets the eyelct therein nccurntely` und expeditiously. l accomplish this object by providing two 'cooperating cyelet-sets, one of which has n centrally disposed punch and the other of which has means for forcing the stock upon the punch. These elements are preferably so associated that by one progressivo movelncln ofthe operatlng luech- :mism thc hole is punched, the stock is forced upon the punch so that the lutter projects Y beyond the stock, thel barrel of the eyelet is carried between the unch and the stock surrounding the `uncied hole, and finally saidlmrrcl 1s cle-nc ied by coming in to contact with the setting device associated with the punch. lt is obvious that the diameter ol the punch ut its cutting edge must he solucwhul. less thun thel diameter of the lm rrcl of thereby injure the saune. Therelue lo insure the proper setting olthe eyrlvt n nd io utilize the punch ns uV guide for the eyeletJ it is-i1nportmlt to provide menus lor forcingthe. stock upon the punch before the eyelet is i11- serted in the punched hole. lf this were not done, the barrel of the. eyelet would come into contact with the stock und have n. tendency to become displaced before oei prop erly guided by the punch into tt. hole in the stock. The Ineens lor forcing stock upon' the punch preherubly consists ol :i yielding sleeve surrounding the eyelet-set which carries the eyelet. This cyelelfset has associated. with it u centrally disposed finger to )ick up the eyelet und also to Wilp-crete with the punch. The end o this `linger is made of a size to slide snugly in .e Ji: the tubular punch und.cooperate therewith to produce u. sheurinu' notion ou the stock in cutting` 'the hole. ily nie-ens oi' tin structlon the use ol' o punch-hlm# dcred unnecessdi@r und ihe unch ref nuins sha-rp much longer thun it oticrwise would. The finger is urrru'iged to )reject vinrtlmr thun the sleeve und is iiiel'ern. ily mounted so uis to yield for n` short distcuce und to stop before it has been retracted as fur as the uornmlpo'sition of thc` sleeve. The linger is thus allowed to yield if it should. strike the rncewny while nt the same time it enuuot l): retracted lufr enough for the sleeve to come into contact with the stock before the p\ un.hini: operation trikes pince.

Therefore when thc sleeve and the stripper cerne into contact with the stock lrorn opposite `sides the sleeve continues its progressive movement and forces the stock upon the -punch while the stripper is retrau'lcd relu Sl i) llll tively to the punch. When the retrograde movement of the sleeve occurs it is evident that the stripper will move forward rela-- tively to the punch and strip the eyelet and the stock in which it has been set from the punch.

Referring sido elevation, partly in section, of afootpower eyelcting machine embodying the features of this invention; Fig. 2 is a vertical sectional view showing the parts in the position which they occu y just after an eyelet has been taken from t e raceway; Fig. 3 is a vertical sectional view showingr the parts as t ey appear just after the punched; Fig. showing the stock forced u on the ign 5 is a vertical sectiona view s owing the parts at the time when the eyelet is set, and Fig. 6 is a perspective view of the combined upper set and punch and the finger. In the drawings 2 designates a table or other support to which a fra1ne4 for the machine is attached. Theupper setting device is carried by a holder 6 secured in an opening in the frame by set Screw 8. lower setting device is carried by a plunger 10 mounted for reciprocation in the guideway 12. The mechanism for imparting a reciprocatory motion to the plunger comprises a lever 14 pivoted at 16 to the frame, said lever being connected at one end by a rod 18 to a foot-treadle or other actuating means (not shown) and at its other end being connected to the lower end of the plunger 10 bv means of links 20 and 22 at whose pivotal point is pivoted a guiding link 23 ivoted at its other end on the frame. The lin 22 is ivoted t0 the lower end of the plunger an hasta laterally rejecting arm 24 which is provided with a ro ler 25 and an engaging foce 26 to produce a rocking movement of a lever 28 by rollers 30 and,y 32 thereon. A raceway 34 supported on the lever 28 is shifted thereby,

I t is evident that when the rod 1S is depressed the plunger 10 end e 'elet in the raceway will be engaged and t ien the raceway will be shifted out ol' the way ol" the setting devices by the roller 25 engaging the roller 30. just described constitutes no part of this invention and no further description of it will be necessary. n

Referring now to the lower settin 1 device, it will be seen that this is carried by the plunger 10 and is reciprocated thereby. A finger 44 has its lower end extending within a recess in the plunfer and it is allowed to yield relatively to t a spring 46 located between a The mechanism 5 1e plunger b means ol l s oulder 48 l eyelet-set, a finger at the center of said latter on said linger and the bottom wall 50 of the recess." Around the u per portion of the finger is a sleeve 52 w 1cv constitutes the lower set and which ma be held on the plunger 1() in any suita le manner. `The upper vend of this sleeve is preferably recessed at 54 to accommodate the eyelet. Surrounding the setting device isa sleeve 56 which is normally forced upwardly by a spring 58 so that its u per end is be ond t ie end of the setting evice. This seeve is slidably secured to the settin device b a screw 60 which extends into a s ot 62 therein.. The upper setting device v64 is provided with a hollow centrally de nding unch 66, fthe outer surface of whic is inclined and mer d to the annular recess 67 within wliic the `nd of the eyelet is clenched. The setting device 64 is surrounded by a stripper 68 having an annular shoulder 7() for enga ement with an annular shoulder 72 on t e settinf device. The stripper is held yieldinglyiy a spring 74 located between the shoulder 7() and the end of the holder 6. The spring 74 is considerably weaker than the s rin r 58. The u per end of the `finger 44 is ltteto slide snug ywithin the punch66. The oeration of the mac e 1s as follows ce-e-'l c cperator holds the stock' a in the the actuatin rod 18 whereby the plunger 10 1s raised. T le finger 44 is elevated. and en-4 ters the end eyelet in the racewa 34. Said raceway is then retracted into t e position shown in Fig. 2 and the linger continuing to rise comes into contact with the punch 66 to out a hole in the stock, as shown in Fig. 3, the punching being indicated by the refer- The plunger 10 continuing to advance, the sleeve 5 comes into contact with the stock and forces it upon the punch as shown in Fig. 4, the stripper 68 at the same time being forced upWardly. lf'pon thc vlinal u ward movement of the plunger the nyclet is guided over the punch, hot wenn the saine and tiie wall surroundin 111e hole punched. in the stock, and the end y ol' the nynlcl. is clenched lcontact with the upper setting device. en the plunger returns to ils initial position the sleeve 56 retires from contact with the stock and the strip wr 68 forces the stock and the eyelet, v. hic i has just been set, oli' of the punch 66.

While thi.- invention has been shown and' described as applied to a foot-power machine, it is evident that it may be applied to any suitable eyeleting machine.

Iaving described my invention, what I claim as new and desire .to secure by Letters Patent of the United States is 1. In a machine of the class described, the combination with an eyelet-set, of a tubular punch centrally i isposed with relation thereto, a stripper surroundingjsaid set, a second sot which nots in conjunction with. lQuid punch l to form :L holc in the stock, und u yicldingr slocvc surrounding said hitter cyclcl -sct consti-uniud and :irl-:mired to forco tho stock upon thc. punch n'hcrc )y thc hulor projccts i hcyonil thc stock.
