EYELETING-MACHIN E.

Specication of Letters Patent.

Patented Aug. 13,1912.

To all 'whom it may concern.'

Be it known that I, JOHN J. DoiDGE, a subject of the King of Great Britain, reslding at South Framingham, in the county of Middlesex and State of Massachusetts, have invented a new and useful Eyeleting-Machine, of which the following is a specification.

My invention relates to improvements in foot-power machines for setting eyelets and the like, and especially to that type which comprises a normally stationary upper eyelet set, a movable lower eyelet set, said sets also constituting a punch, and a raceway which is movable into and out of the path of travel of said lower set for delivering eyelets thereto; and said invention consists generally in improved mechanism for operating the lower set and the raceway, and in certain other features, all as hereinafter set forth.

One object of my invention is to provide a machine for taking eyelets from a raceway and setting them in stock after punching the holes therefor in said stock, at each cycle of operation of the machine, and in which the eyelet punching and setting and the feeding devices are so combined that a single progressive movement of the operating mechanism takes an eyelet, punches a hole in the stock and sets such eyelet therein accurately and expeditiously.

Other objects will appear in the course of the following description.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a machine which embodies a practical form of my invention; Fig. 2, a top plan of the stock or work table with its gages, the edge of the table which appears at the bottom in this view being the front edge thereof, and, Fig. 3, a side elevation in partial section of said machine, showing the operating mechanism and parts disposed at the opposite extreme to that in which they appear in Fig. 1.

Similar figures refer to similar parts throughout the several views.

In Figs. 1 and 3, 1 represents a portion of a table or bench upon which my machine is mounted. A frame or support 2, having a base 3 which rests upon and is secured in any suitable manner to the table 1, carries the operating parts and members of the machine. The front of the support 2 is cut away at 4 to accommodate a work table 5, and there is a vertical passage 6 in said support below such cut-away portion 4; for a plunger 7, and a vertical passage 8 through the support above such cut-away portion for an upper set 9 and an adjustlng screw 10 therefor. The axes of the plunger 7 the set 9 and the screw 10 are in the same vertical line. The upper set and its adjusting screw are in what may be said to be the head of the frame or support. The back wall of the passage G is slotted at 1l to admit into such passage the front terminal of a lever' 12 which is pivoted at 13 to a lug 14 that rises from the base 3 behind such slot. An operating lever 15 is pivoted a short distance below its upper end, at 16, to a lug 17 that rises from the base 3 at the back end. The table 1 and the base 3 are slotted to accommodate the lever 15. The lower portion of the lever 15 is broken olf in Figs. 1 and 3, but such lever is of the usual pedal and spring' operated variety. A spring 18 ex tends from a suitable lug on said lever to a suitable hook projecting below the underside of the table 1 and servosto tension that part of the lever which is below the pivot 16 forwardly and that part of the lever which is above said pivot rearwardly.

Pivotal connection between the upper end of the lever 15 and a projection 19 rising from the rear terminal of the lever 12 is had by means of a bolt 20 extending from said lever 15 into a slot 21 in said projection, an anti-friction roller 22 of the usual type being mounted on that part of said bolt that is in said slot. The arrangement of these members is such that, when the upper terminal of the lever 15 is rocked forward and downward, the rear terminal of the lever l2 is carried downward, through the medium of the bolt 20 and its roller operating in the slot 21, and at the same time the front terminal of said lever 12 is carried upward; and the return stroke of such upper terminal of said lever 15 restores the lever 12 to its former position. The shape and position of the slot 2l is in the main responsible for these movements on the part of the lever 12.

A vertical rod 23, which may be adjustable, is set into the base 3 in front of the lever 15, and is designed to afford a stop than the diameter of an eyelet barrel in-V tended to lie and slide between them, and spaced from'the lioor suliiciently to permit the head of the `eyelet to travel between vthe ioor and the adjacent faces of said rails.v Such a floor is represented at 24, and one of j suchv rails is represented at 26. A hopper 27 for eyelets is fastened Von the raceway at the upper, rear end. The floor 24 is suppor-ted by and on a bracket 28, which bracket is provided with two -horizontal fixed rods 29 and 30 which Vare slidingly mounted in;

lugs `31-31 and 32 on one side of the support 2 there being in this case two lugs for the rod 29 and lone for the rod 30. In the lowerportion :of the bracket 28 is an irregular-shaped cam-slot 33 in which .operates an l anti-friction roller 34 ,on a stud 35 that prof jects from the rear end of the lever 12. The

aforesaid rear end, including the projection 19, of the lever 12 is situated between the lever 15 and the bracket 28. The construction and arrangements of the part-s just described is such Ythat the downward movement of the rear end -of vthe lever 12 causes, through the medium -of the stud 35 and its ro-ller in the cam-slot 33 in the bracket 23, the raceway to movebackward, and the upward movement of said rear zend of said lever 12 causesv said raceway' to move forward, through the same medium, as will be plainly seen upon referring to Figs. 1 and 3.

Having now outlined my machine in a somewhat general way., I will next proceed to .take it up more in detail.

The plunger 7 has a bifurcated base 36 to receive the front end or head of the lever 12, and said base is provided with an anti-` friction roller 37 on `a ,pin or stud 38 above said head, zand with a pin 39 below said head,.so that said plunger must follow the head 'in its 'up and .down movement, or in other words, is reciprocated vertically in the passage 6 by the lever 12.

40 is =a bushing in the upper end of lthe passage 6 for the plunger 7 and 41 a setscrew for such bushing. Seated in 4the upper .end .of the plunger 7 .and held against upward .displacement by a set-screw 42 is a set 43 which also constitutes :the male member of a punch. The vcombination Ipunch and set 43 operates 4in conjunction with the set 9, which latter constitutes the female member Lof the punch, in the usual manner to punch the hole in the stock, and introduce an eyelet 44 and upset it therein, as represented at 45, in Fig. 3, wherein a piece of stock is also represented :at 46.

The adjusting screw 10 is Atapped into the passage 8,bears on the `upper yend of the set 9, and affords means for locating said set at a lower point, should occasion require,

, than it is located when its shoulder is against the underside of the head of the support 2. A set-screw 47, tapped into the front of the head of the support 2 as the set-screw 42 is tapped into the front of the plunger 7, serves to hold the set 9 against downward displacement, and must be loosened, of course, before attempting to adjust said set.

The set 9 and the screw 10 are .bot-h hollow .so as to allow the material punched from `the stock to pass upward and escape through the top of said screw. 48 is a set-nut for :the screw 10.

Upon loosening the set- screws 42 and 47, the sets 43 and 9 can be removed andV new ones of t-he saine or a different size substituted, thensaid set-screws are .retightened The machine is able to handle :as many different sizes of eyelets as there are different sizes of sets, .provided the feed be attended `to in lthe manner hereinafter more fully def scribed. The sets are changed in the manner just explained. The shanks of the sets, which fit into the sockets provided to receive them, are always the same regardless of the size of the sets themselves. The small `upper portion of the set 43 isv the part that fits the eyelet Aand venters the above-men tioned passage, 49, in Vthe set 9. These sets do not differ materially in general construction and operation from other sets in common use for the same purpose.

The table 5 is supportedlfrom the front of the support 2, above =the plunger 7, on two brackets v50 to which said .table is .securely fastened by screws 51. The base of each bracket 50 isattached to one side of the support 2 by means of .a pin 52 and a thumb- `screw 53. IIn the center of the table 5 is a hole 54 through which the set 43 operates. This table is equipped with two gages for the work, one of which determines the distance in from one edge 4of the stock that 4the eyelets are to be set, and theother of which determines l the distance between eyelets. The first of these'gages com-prises a horizontal plate or slide v55 provided at its inner end with a vertical finger 56 which is directly ybehind the hole 54, and the kother gage comprises a horizontal strip or slide 57 provided at itsinner .end with a vertical linger 58 at one side of said hole.

The slide 55 rests on the .table 5 :and is adj'ustably held .thereto bymeans of a screw 59 anda thumb-screw 60. There is a slot 61 in the slide 55, which extends from a poi-nt near the front edge of said slide back-ward through the rear edge of the same, and the screw 59 passes from above through this slot into threaded engagement with the table. The thumb-screw 60 passes from below through a slot G2 in the table into threaded engagement with the slide 55, such slot (32 being parallel with the slot (51. Adjustment of the finger 56 is effected by loosening the screw 59 and the thumb-screw (30, moving the slide 55 backward or forward accordingly as it is desired to set the eyelets farther from or nearer to the edge of the stock, and then retightening said screws.

The slide 57 is held against the underside of the table 5 by means of a thui'nb-screw G3 which passes through a longitudinal slot 64 in said slide into threaded engagement with said table, and the finger 58 extends through and operates in a longitudinal slot 65 in the table. The finger 58 projects above the top of the table, and its adjustment is effected by loosening the thumb-screw G3, moving the slide 57 toward or away from the hole 54 accordingly as it is desired to locate the eyelets closer together or farther apart in the stock, and retightening said thumb-screw.

During the operation of the machine, the stock is held with one edge against the inger 56, and moved along in that position after the setting of each eyelet, so that all eyelets set shall be the same distance in from such edge; and each eyelet as set or immediately after being set is placed over the finger 58 to determine the position of the next eyelet.

The table 5 is cut away to whatever extent may be necessary to accommodate the toe of the raceway, and some adjustment for said table is afforded by slotting each bracket 50 at the base, as shown at 6G, in Fig. 1, for the pin 52 and the thumb-screw 53.

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, one of which appears at 67, and a spring stop 68 for the lowermost eyelet 44. These elements and the manner in which the eyelets are controlled and permitted to be fed by them are fully set forth in United States Letters Patent, No. 1,012,999, issued to me December 26, 1911.

The hopper 27, which is a reservoir for the eyelets, has a cover 79 and is provided with the usual internal agitator brush (not shown) which is mounted on a shaft or spindle 81 journaled in the floor 24 and the rear end of the bracket 28. A pinion 82 tight on the lower end of the spindle 81, a suitablymounted loose gear 83, an operating plate 85 on the hub of said gear, and a connectingrool 86 having one end pivoted to a projecting part of said plate and the other end loosely connected with a bolt 88 which rises from a lug 89 on the support 2, 1are employed to operate said spindle. The gear 83 and plate 85 are held on a stud which projects below thc floor 24 at one side of the spindle 81., by means of a washer 99 and a nut 100.

A selector 91 is attached to the hopper 27 over an opening therein to insure the presentation of the eyelets to the raceway in the proper position, that is, with their heads down on the iloor 24 and their barrels projecting at right-angles to said iloor. The base of this selector is provided with a plurality of notches 92 each of a size and shape to admit of the passage of a single eyelet when resting on its head, barrel up, on the floor 24. The selector' 91 has two lugs 93 by means of which and two screws 94 said selector is fastened against the outside of the hopper. "lhe above-mentioned eyelet-feeding mechanism and appliance are more fully set forth in the l1ereinbefore-mentioned patent.

ssuming that the parts are all properly adjusted, the hopper is supplied with eyelets and all is in readiness, the operation of the machine is briefly as follows: lhe stock is placed by the operator on the table against the finger 5G and in the right position relative to the hole 54, and then the operator forces back the long arm of the lever 15 against the resiliency of the spring 18 until the short arm of said lever strikes the stop 23. This action on the part of the operator results in rocking the lever 12 to elevate the plunger 7 and thereby cause the set 43 to pick the eyelet immediately above it in the raceway, and `in conjunction with the set 9 punch the hole in the stock, insert the eyelet carried by said set 43 in such hole and upset it therein; and in withdrawing said raceway from the path of the rising set until the raceway is at the rear end of its travel. Vhile in the act of punching the hole in the stock for the eyelet and upsetting the latter the stock is lifted from the table 5, as shown in Fig. 3, but said stock does not riso above the top of the linger 5G. and said hnger may be bent over forward, if desired and as shown, to prevent the edge of the stock which bears against said linger from passing upward clear of the finger.

The operator next releases the lever 15, and the spriiig 18 then acts to return said lever to its former or initial position and so to restore the rest of the mechanism to the position which it originally occupied, that is to say, the lever 15 elevates the long arm of the lever 12 and so causes the plunger 7 with the set 43 to be depressed, and said lever also actuates the raceway forward to the position where the lowermost eyelet therein is directly in line with said set and ready to be removed from said raceway 'when next the set rises. lVhen the set 43 descends through the hole 54 in the table 5, it leaves the stock or work on said table,

and the operator moves it along until the eyelet just set. can be slipped over the finger 5S. The set eyelet is then placed over the finger 58, and the operator proceeds .to set the next eyelet in the same way he did the first, the operation or the series of operations each time being the same as already fully described.

The operating mechanism for the plunger and the raceway is so timed that the latter does not begin to move back until the set 43 has risen into engagement with the first eyelet; but the backward travel of the raceway is accomplished very quickly when once begun so as to clear the way for the rising plunger 7 with its set and the eyelet thereon, and the forward movement orp said raceway is also accomplished without loss of time after starting in order that a new cyelet may be speedily locatedin the path of the movable set.

Each time the raceway travels forward the brush spindle 8l is caused to make a partial revolution and consequently to cause the eyelets in the hopper to be agitated and those that are in proper position adjacent to the selector 91 to be forced out through the latter into said raceway, and it is by this means that the raceway is kept constantly supplied with eyelets.

The machine can be operated as fast as the lever l5k can be actuated by the foot of the operator and the spring 18, the adjustment of the work on the table 5 being practically the only limit to speed.

lt is obvious that numerous departures in the construction and arrangement of some or all of the parts of this machine, such as will readily occur to one skilled in the art,

Ymay be made without departing from the nature of the invention or going outside of the scope of the claims.

Vilhat l claim as my invention, and desire to secure by Letters Patent, is-
