FEEDING DEVICE.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Original application led July 28, 1909, Serial No. 510,123. Divided and this application led September 9, 1910. Serial No. 581,2?5J

To all whom it may concern: I

Be it known that I, JOHN J. Demon, a subject of the King of Great Britain, residing at South Framingham, in the county oi' Middlesex and State of Massachusetts, have invented certain new and useful Feeding Devices, of which the following is a specification, the same being a divisional part of an application tiled Vby me in the United States Patent Office July 28, 1909, Serial No. 510,123.

My invention relates to improvements in machines for setting eyelets and the like, of the type vhich comprises stationary and movable eyelet sets and a raeoivay movable into and out ot the path of travel of the movable set for delivering eyelets thereto, and more especially to devices for feeding eyelets in such a machine. and said invention consists of improved mechanism for agitating the v eyelets in the hopper, ot certain peculiar adjustable means for the raceway, and other features, all as hereinafter set forth.

The object of my invention is to provide means, in a machine of the class above mentioned, for expeditiously and quickly feed ing eyelets to the punching and setting members of such machine, to the end that an eyeletcan be set in the stock at each progressive movement of the operating mechanism of the machine.

A further object is to atl'ord means whereby `the machine is enabled to feed and handle evelets of different sizes.

I attain these objects by the means and mechanism illustrated in the accompanying drawings, in whieh- Figure 1 is a side elevation ot a machine which embodies a practical i'orm of my in vention, portions heine broken away to disclose more clearly the manner in which the movable-set plunger is ol'ieraled; Fig. 2, a side elevation ot the eyelet hopper detached and without the selector; Fig. 3, a side elevation of said selector. dotaehed'; Fig. 4, a top plan ot the machine, thc cover of the hopper being* open; Fig. 5, a bottom View of the upper, roar terminal of the raeeway, and ot' the attached mechanism for agitating the brush in the hopper above; Flg. (i, a bottom view of said mechanism Without the Washer and nut; Fig. 7, an enlarged top plan ot the lower7 forward terminal or toe of said raceway; Fig. 8, an enlarged side elevation or edge view of such toe with its attachments, and, Fig. 9, an enlarged underside view of the parts shown in the two preceding views.

Similar iigures refer to similar parts throughout the several views.

In Fig. 1. 1 represents a portion of a table or bench upon which the machine is mounted.

The machine with which the present invention is incorporated is described briefly as follows: A frame or support2, having a hase 3 which rests upon and is secured to the tahle 1. carries the operating parts and members ot the machine. Mounted to rcf-,iprocate in a vertical passage 6 in the i'ront part ot the support 2 is a plunger 7. above which is ai fixed set 9 in the head ot' said support. The haelt wall of the passage, fi is slotted at 11 to admit into such passage the front terminal of a lever `12 which is pirated at 13 to a lug 14 that rises from the base 3. An operating lever l5 is pivoted at 1G to a lug 17 that also rises from the hase. The table 1 and the hase 3 are slotted to accommodate the lever 15. Although the lower portion oi the lever 15 is broken ott' in Figi. 1. itwill be. understood that such lover is of the. usual pedaland springopornted variety, the spring appearing at 1S. Pivotal connection between the upper end ot' the lever 15 and a projection 19 rising from the rear terminal of the lever 12 is had by means of a bolt 2() extending lrom said lever 15 into a slot Q1 in said pro jet-tion. the arrangement of parts and the shape and position ot said slot turing;V such Vthat, when the upper terminal of the lever l5 is rocked forward and downward. the rear terminal oi said lever 12 is carried cimvnward. through the medium ot said holt and au anti-friction roller QQ thereon operating' in said slot, and at the saine time the. front terminal of said lever 1Q in carried upward, While the return stroke it such upper terminal of said lever 15 4'estores the lever 12 to its former position. 23 is a stop for the lever 15;

A raceway of the preferred type comprises a smooth floor which inclines down .Such a floor is represented at 24, and such rails are represented at 25 and 26. The rail 25 is preferably xed, `while the rail 26 is preferably adjustable in the manner and for the purpose presently-to be explained. A hopper 27 for the eyelets is fastened on the raceway at the upper, rear end thereof. The Hoor 24 is supported by and on a bracket 28 which is provided with two horizontal fixed rods 29 and 30 rlidingly mounted in lugs 31-31 d 32 on one side of the support 2. In t e lower portion of the bracket 28 is an irregularshaped cam-slot 33 in which operates an anti-friction roller 34 on a stud 35 that projects from the rear end of the lever l2. The parts just described are constructed and arranged so that the downward movement of the rear en'd of the lever 12 causes, through the medium of the stud 25 and its roller in the cam-slot 33, the raceway to move backward, and the upward movement of said rear end of said lever causes sald Iaceway to move forward, through the same medium.v

The plunger 7 has a bifurcated base 36 to receive the front end or head of the lever l2, and said base is provided with an anti-fric- `tion roller 37 on a in or stud 38 above said head,V and with a pm 39 below said head, .so that said plunger must follow the head 1n its up and down movement. The plunger 7 carries a set 43 which operates 1n conjunction with the set 9 in the usual manner to punch the hole in the stock and introduce an eyeiet 44 and upset it therein. y

The toe of the raceway or that part of the raceway that comes into intimate relation to the set 43 is equipped with adjustable members 67-67 and a spring stop 68 for the lowermost eyelet 44, est shown 1n F lgs. 7, 8 and 9. The Hoor 24 has a central indentation or recess 69 in its front end, and the members 67 have their rear ends pivoted at 70 to the underside of said floor back of said recess and extend forward beneath the same. The members 67 are lin the form of arms each with an indentation 71 in its inner edge at the front terminal. The stop 68 is a resilient member having its rear end fastened at 72 to the underside of the floor 24, and its free forward terminal bent over in front of the open end of the raceway, such termlnal extending about half way across such open end. The lowermost eyelet 44 is recelved on and sup orted by the indented terminals of the mem ers 67 and is prevented from escaping from the raceway by the stop 68.

The indentations 71 permit the set 43 to ass up and plck the eyelet on the mem ers 67, and then when the raceway isV moved backward out of the way of said set the eye-V let and the set force the stop 68 to'one side, but said stop vimmediately returns to tion in front of the next eyelet which s ides down in the raceway onto the members 67.

In order to make, provision for supporting eyelets of different sizes on the members 67 and to accommodate such members to movable sets of differentsizes, a rightand left-hand screw 73 is ta ped into'lugs 74-74 on the bottoms of usai members, and a slotted lug 75 is fixed on the bottom of the licor 24 to receive said screw between its head and a set-nut 76 on the screw The set-nut 76 and the head of the screw 73 tightly embrace the lug 75 and so hold the members 67 in place, and adjustment ot said members is effected by loosening said nut, turning said screw in whichever direction may be necessary to open or closesaid members as occasion requires, and retightening the nut.

As already noted, the guiding rail 25 is fixed, while the guiding rail 26 is laterally adjustable so as to adapt the raceway to eyelets of different sizes. The space for the barrels of the eyelets is the only one that need be changed, since the space for the heads of the eyelets, that is, the space between the door 24 and the guiding rails, is large enough for the largest eyelets and does not require changing for the smaller ones. In this case transverse slots 77 are provided in the guiding rail 26 for screws 78 which pass through such slots into threaded engagement with the floor 24. Upon loosening the screws 78 the rail 26 can be moved to make the space between it and the rail 25 wider or narrower as may be required, after which said screws must, of course, be reseated.

The hopper 27, which is a reservoir for the eyelets, has a cover 79 and is provided with an internal agitator brush 80 which is mounted on a shaft or spindle 81 journaled in the floor 24 and the rear end of the `bracket 28. As is well known, the object of the brush 80 is to sweep the eyelets out of the` hopper into the raceway, and to imart the necessary motion to said brush or this purpose I employ a inion 82 tight on the lower end of the spindle 81, a g ar 83 loose on a stud 84 set in the bottom oi the floor 24, an operating plate 85 loose on the hub 96.01 sald gear and having a slot 97 therein for a ball 98, and a connecting-rod 86 4having one end pivoted at 87 to a projecting part of said plate and the other end loosely connected with a bolt `88 which rises lfrom a lug 89 on Ythe side of the support 2 opposite that Where the lugs 31 are located.

4The bottom of the slot 97 is covered and osif reci rocated, through the gear 83 and plate 85 are held on the stud 84 by means of a Washer 99 secured on said stud against the hub 96 by a nut 100. The slot 97 opens on the side of the hub 96, or in other words said hub forms one side, so to s eak, of said slot, and the front end of the s ot is narrower than the rear end, conseuently the ball 98 acts as a clutch to carry t e gear 83 with the plate 85 when the latter is rotated backward, as shown in Fig. 6, but'- is free and inactive in the wide end of said slot when said plate is rotated forward. The gear 83 meshes with the pinion 82, hence it is obvious that the brush 8O is intermttently rotated by the raceway as it is the medium of said, mes ing members and the connecting-rod, because, said raceway carries all of these parts excepting the front end of saidconnecting-rod which is pivoted to the support 2 at 88, and when the raceway moves forward the plate 85 pivoted to the rod as it is at 87 is caused to make a partial revolution rearwardly and to carry with it the gear 83, since the parts are now locked together by the hall 98, thus rotating the pinion 82 with the brushin the opposite direction, and

when thev raceway, moves backward said plate is caused to malte a partial forwardly without said gear, since said ba releases said parts at this time and so p mits the plate to act without the gear, said pinion and brush remaining idle with the gear. In this way and by this means ,the brush is intermittently rotated in one direction from' the reciprocating raceway, with the resultI that eventually all eyelets in the hopper are presented to a slot or o ening 90 in one side at the bottom of sai hopper, which communicates with the raeeway, and are thrust through such opening into said raeeway. This last result is made possible by reason of the fact that the guiding rail 25 joiristhe hopper at or adjacent to the loiier'cnd of the opening 90, while the guiding rail 26 curves around the front ot said opening, thc arrangement being such that the upper portion of the raceway includes this opening.

A selector Ell is attached to the hopper 27 over the openin 5)() therein to insure the presentation of tre eyelets to the raceway in the proper position, that is, with their heads down on the floor 24 and their barrels projecting at right-angh-fs to said tioor. lhe hase of this selector is provided with a plurality of notches D2 nach of a. size and slfipe to admit ot' the passage ot' a single eyelot when resting on its head, barrel np, on the lloor 24. The selector' U1 has two lugs 93 by means of which and two screws 94- said sclector is fastened against the outside of the hopper. lf the machine is to handle larger or smaller eyelets, a` selector having larger or smaller notches U2 is used, the screws 94,

revolution vtor which two holes 95 are tapped into the hopper (see Fig. 2), affording ready means for making the change.

Each time the racew ay travels forward the brush 80 is caused to make a partial revolution and consequently to evitate the eyelets in the hopper and orce 'iose that are in proper position adjacent to the selector 91 uit through the latter into said raceway, 'and it is by this means that the raceway is kept constantly supplied with eyelets. The intermittent action of theJ brush eventually, by its wiping action on the eyelets in the hopper, causes every eyelet to be presented head down to the vselector and then to be expelled from said hopper.

More or less change in the construction and arrangement of some or all of the parts which comprise my invention may be made Without departing from the nature of said invention.

What I claim as my invention, and desire to secure by Letters Patent', isi 1..'1`he combination, in an eyeleting machine, of a movable raceway comprising a floor and two guiding rails spaced apart and fromsaid floor, the latter having a recess in its fbnt end for the passage of a set, adjustable eyelet-supporting members attached to the raceway and extending beneath said recess, such members being separated at their forward terminals to permit the set to pass between them, and a resilient stop for eyelets in said raceway, such stop consisting of a Hexible member which is attached at one end to the raceway and extends at the other terminal over the discharge end of the raceway to, hold back the eyelets under normal conditions, but being adapted to yield when the raceway is retracted to release the lowermost eyelet and leave it on said set.

2. The combination, in an eycleting machine, of a movable raceway comprising a door and two guiding rails spaced apart and from said floor, the latter having a recess in its front end for the passage of a set, eyelet-supporting members pivotally attached to the raceway and extending beneath said recess, such members heilig separated at their forward terminals to permit the set to enter between them, and means ot adjustment for said supporting members whereby the amount of their separation can be increased and decreased.

The combination, in an eyelcting machine, with a reciprocating raceway, a hopper carried by said raceway, a spindle mounted in said raceway and hopper, an agitator brush in the hopper on such spin- .(lle, a pinion on such spindle below the raceway, a. gear mounted in mesh with said pinion below the raroway, an actuating member tor said gear loosely mounted relative to the latter, a. clutch member between said actuating member and gear, the arrangenunt be- 4 1,012,999 ing such that said clutch member frictionthe racew'ay reciprcies, ally engages both aetuatin member and tary motionin one directlon bem gear and locks them toget er, when said actuating member is moved in one direction, and releases such part when said actuating member is moved in 'tbe opposite direction, leaving said gear stationary, and means to cause said actuating member to oscillate as Witnesses: l
