To aZZ whom,- izi may concern.-

Be itknown that I, EDWIN B. Srmrrson, J12, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Eyeleting-Machines, of which the following is a specification.

My invention relates to those machines for setting eyelets which are more commonly termed eyeleting-machincs.

I will describe in detail an eyeleting machine embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure 1 is a side elevation of amachine embodying my invention. Fig. 2 is a plan of the same, a portion of the bedplate being broken away to reduce the size of the figure. Fig. 3 is a vertical section through the head of the machine upon about the plane indicated by the dotted line was, Fig. 1, the ends of the levers which operate thepluugerand the anvils and piercers being, however, shown in end view; and Fig. A is a view similar to Fig. 3, but showing the parts in the position which they occupy at the moment of setting the eyelets.

Similar letters of reference designate corresponding parts in all the figures.

A designates the frame ofthe machine, which has at the bottom a base plate or bed, A, on which it stands, and by which it may be secured to a table or support, B. As here represented, tlle machine is constructed for setting two eyelets at one and the same operation, and there are employed two piercers, O, and two yielding followers, D, which are arranged in line with each other, as shown best in Figs. 3 and 4, the piereers 0 being here represented as uppermost and working downward, and the yielding followers D being below and working upward. At the base or inner end of each piercer O is a shoulder, a, and, as here represented, each shoulder a is upon a vertically-movable rod, 0, and forms the anvil against which the eyelet is set. The rods 0 are fitted to bores a formed in the head a of the machine-frame A, and around each rod is a spring, a, which bears at the upper end against a shoulder, 0 upon the rod, and at the lower end against a shoulder, a, in the bore a. The springs c exert a constant tendency upon the rods (3, which here form separate anvils to elevate the rods sufficiently to shield the piercers C within thehead a of the machine-frame; but by a force applied to their upper ends the rods may be pressed downward, so as to project the piercers 0 beyond the end cl of the head a, and to project the shoulders c as far as the end (I of the head and bring them to the position for setting eyelets, or to setting position, as shown in Fig. 4.

The yielding followers D are carried in a plunger, 1), which is fitted to a guide, (i in the frame of the machine, so as to provide for its vertically-reci proeatiug movement therein. The followers D are adapted to yield down ward within the plunger, and, as here represented, said followers have heads d at their lower ends, and are fitted to slide within bores d formed in the plunger D. Into each bore d", and above the head d of the follower D, is inserted a sleeve or bushing, (1", through which the follower works. Beneath each followerD and in the bore d is a spring, quently when the follower, which normally projects beyond the plu nger, strikes against an object the spring cl is compressed and the follower yields downward within the plunger. The sleeve or bushing d", which is inserted in each bore d" to hold the follower D in place, may be considered as a part of the plunger.

E designates a work-table or fabric-presser, which has imparted to it a vertical movement, and which is supported by springs, so as to permit it to yield. In the present example of the invention the table or presser E is sup ported by rods 0 from a yoke, E, which is secured directly to the plunger 1). As here represented, the yoke E has a ring-like portion, e,which is fitted upon the upper end of the plunger D and there secured by set-screws c and said yoke also has downwardly-extending arms e provided with lugs or ears 6', in which the rods 6 slide. As here repre sented, the rods 0 have at their lower end shoulders which are formed by cross pins 0 and which strike against the lugs or ears 0 when the rods are raised to their highest position, and thus prevent the withdrawal of the rods and limit the upward projection of the table or presser E. Upon the rods 6 are placed coiled springs c, which hear at one end upon the work-table or presser E and at the lower end against the uppermost lugs or ears, 6, and these springs serve to yield downward when (1*, and conseill the work-table E strikes against a part which forms an abutment for it to hold the work against, and which in this instance is formed by the lower end,d,of the head a of the frame.

F designates a lever, which engages, as here represented, with a pin, f, in the plunger D, and which is fulcrumed atf. To the rear end of this lever is attached a rod, E, which may be operated by a treadle, (not here shown,) and f f are stops for limiting the two positions of the lever by striking against the bed-plate A, and which are here represented as screws inserted in the lever. The stop f limits the downward movement of the plunger D, which is produced, as here represented, by a spring, E attached at the points f to the rear end of the lever F and to the frame A, and the stop f limits the upward movement ofthe plunger, produced by drawing down the rear end ofthe lever by the rod F.

G designates a supply-hopper for eyelets, which is constructed so as to deliver eyelets at opposite sides thereof, and G designates two supply-channels, which lead from opposite sides of the hopper G and thence, at an incline, downward on the paths of the yielding followers D. The construction of the hopper G is well known in machines of this class, and it contains, as in other machines, a brush which has a short arm or crank, 9, upon its axle g, and this short arm or crank g is coir nected by a rod, 9 with the fixed frame A of the machine, and as the hopper and feedingchannels are moved laterally away from and toward the path of the yielding followers D the brush within the hopper G receives from the rod 9 a short oscillation, which aids in discharging the eyelets through the openings in the sides of the hopper. At opposite sides of the hopper and at the receiving ends of the feeding-channels G are attached guards g", which overlie the receiving end portions of thefeeding-channels and prevent displacement of the eyelets.

Vhere the machine is intended for setting only one eyelet at an operation, of course two feeding-channels G would be unnecessary, and the eyelet-hopper G would have extending from it only a single feeding-channel, as is usual.

The feedinghopper G and feeding-channels G are mounted upon a bar or support, G, which has a sliding movement in suitable guides. As here represented, the bar or sup port G is constructed with slots 9, which are mounted upon rollers 9 projecting from cars or lugs a on the frame A of the machine, and a sliding movement is imparted to the support G, as here represented, by a lever, G", fulcrumed at g to the frame, and having its one arnng engaging with the bar orsupport G and its other arm q havinga pin-and-slot connection, {1 with the lever F. Consequently as the lever F is raised to elevate the plunger D it acts,through the lever G, to move the support G, and consequently the feeding-channel and hopper,away from the path of the followers D, and when the plunger D islowered the lever G returns the support G" and the superposed channel and hopper to the position shown in the drawings, or allows them to slide back to that position by the force of gravity. For the purpose of limiting the downward and inward movement of the bar or support G so that the lowermost eyelets in the feeding channels will come to the exact position in line with the yielding followers D, I have represented a stop-screw, g inserted in the lever G and bearing against a lug or ear, 9, upon the frame A. As a means of pushing downward the rods 0, which form the anvils c and the piercers O, I may employ a lever, as H, which is fulcrumed at h to the frame A, and one end of which overlies and rests upon the upper ends of the rods 0. The rear end portion,

H, ofthe lever H is curved downward,as shown.

in Fig. 1, and is represented as lying between the side of the frame A and the bar or support G and as intermediate between two projections or rollers, g, on the bar or support G". Consequently as the bar orsupport G is moved in the direction of its length to carry the feeding-channels away from or toward the line of the yielding followers D the projections or rollers g act upon the lever H H, so as to first depress the rods 0 and the anvils and piercers which they carry, and then to relax pressure upon the same and allow them to be raised by the springs 0, applied to them.

In the position of parts shown in the draw ings the machine is inoperative, and there is ample room to introducea fabric between the work-table or fabricpresser E and the abutment (1. (Here shown as formed by the head a of the frame.) hen eyelets are to be set, the fabric is placed upon the table E and the lever F is operated by the treadle. The first rising movement of the plunger D raises the work-table E and causes it to press and hold the fabric firmly against the abutment d, and then the springs 6 yield, while the plunger D continues to rise and carries the yielding followers D through the two lowermost eyelets in the feedingchannels G. The bar'or support G is meanwhile moving away from the plunger, or toward the right hand of Fig. 1, and by its operation on the lever H H forces down the rods 0, thereby piercing the fabric by the piercers C while it is held immovable against the abutment d by the work-table E, and likewise serving to bring the shoulders c, which form the anvils, down upon the fabric, or to project said shoulders as far as the abutment at. Meanwhile, by the rising movement of the plunger D, the followers D,with the eyelets upon them, are brought against the ends of the piercers, and being thus arrested yield into the plunger D while the plunger continues to advance, passes the eyelets over the piercers and through the holes in the worktable E, which are provided for them, thence through the fabric, and, finally, the setting projections 'i, which surround the yielding followers D, and which in this instance are formed by the ends of the bushings d set the eyelets solidly against the anvils c, the parts coming to the position shown in Fig. 4.
