K is a curved rod provided alits upper end with a crank-arn'i l' and journaled just below said crank-arm in a vertical sleeve or box A, which is detachably secured to a bracket on l the frame C. On this rod are strung, as 1 shown in Figs. 2 and 3, the eyelets 1', which are. fed therefrom to the lower die B. The lowerend of this rod is formed with a cavity which fits over the center-pin when said rod is turned into the position in which it is shown in Fig. 3. The crank-arm l' has a spring connection I with the upper end of the lever L, which is fulcrumed at its lower end to the frame C. This lever is intermittently thrust forward against the tension of a retracting-spring by a cam ML N is a horizontally-sliding bar provided at its front end with a slotted plate n, through which therod K passes, and which has two forwardly-projecting tongues 11 21, struck up therefrom on opposite sides of the slot therein and is so shaped that when drawn backward it will support a series of gromet-sections or eyelets n above it on said rod,'as shown in tongues will pass above the flange of the lowest eyelet, permitting it to descend on the rod, while the eyelets above are held back by said plate. The bar N has a 'depending'arm in mittently thrusts the plate n forward against the tension of a retracting-spring..w The cams M and O are mounted on a shaft which is provided with a grooved pulley P and'with a tooth p. (Shown in Fig. 1.) The cam-shaft is normally held against rotation by a dog or detent Q, pivoted to the frame and normally engaging the tooth p, the driving-belt in the meantime slipping on the pulley P. To the dog Q is pivoted a vertically-sliding bar R, the lower end of which projects into the path A spring 2-, con necting said bar with theframe, withdraws it into and normally holds it in its lower position.

The machine hereinbefore described operates as follows: Holes having been punched in the [blanket or other article where the gromets are to be set therein and an eyelet 22 being placed on the lower dieB and'a washer 'u on the forked end of the supportEdirectly below the upper die A, as shown in Fig. 1, the blanket or other article is then placed over the eyelet on the lower die, as indicated by dotted lines in Fig. 1. The operator now-depresses the foot-lever, which acts, through the lever D, to thrust the lower die B upwardly against the upper die A. This movement of lever D operates, through the lever H, to withdraw the carrier F with th support E, sufficieut delay, however, being provided for by 1/ before saidcarrier starts backward.

to permit the center-pin b of the lower die to enter the hole in the washer The initial movement of the support E backward does not materially affect its inclination, the

roller 1' bearing against the guideway on the frame (3; but when the lower end of the slot in the link I engages the pivot-pin-on barrier Fthc-roller 2' is carried upward out of con-- tact with the frame and said support is brought to an approximately horizontal position. As the sup'port E is withdrawn and approaches a horizontal position the projection on the rear end of the pusher e engages with the stop c"on.the frame and is thereby arrest- .ed and caused to thrust the lower washer underneath the free end of. rod G upon the support E into the guide g. Owing to the substantially horizontal position of the support E when it is thrown back, as above stated, this detached washer does not immediately slide into position on the front end of said support; but when the foot-lever is released and thelever D is allowed toresume its original position the carrier F and support E are forcibly thrown forward by the spring J, assisted, it may be, by gravity or by a retracting spring connected with the foot-lever, and

the jar of the roller 6 striking againstthe frameU throws the disengaged washer forward into place between the converging springs g on the sides of-t'he guide g, as shown in Figs. 1 and 6. In its forward position the carrier is arrested when the washer on the forked end of said support is between and directly in line with the dies A and, B by the roller 4 coming in contact with the shoulder 11'. As the rear end of lever-D descends the lug r thereon passes below the lower end of the bar R or a shoulder thereon, so that when said lever is released and is returnedby gravity or a retracting-spring to its original position said lug will engage with said bar and lift the dog Q'out of engagement with the tooth p. The cam-shaft being thus released is caused to make one revolution by the belt passing over the pulley p. The cam M engaging with the lever L throws it forward and throughthe spring connection Z and crank Z: turns the lower end of the rod K, as indicated in Fig. 5, into the position in which it is shown in Figs. 3 and 4. The crank or camO then engaging the arm on the sliding bar N thrusts the plate a forward, separating the lower eyelet '0' from those above it and allow ing it to pass down upon said rod into place on the pin 6 of the lower die. The rod K and the plate 12. are'then returned to their original positions by the retracting-springs and n. The gromet-sections are thus automatically supplied to the dies by the operation of the lever, which forces the dies together and sets saidsectionsin the article to which they are to be applied.

Various changes in the minor rletaile of onupon said carrier, and a stop on the frame .which the gromet-sections are strung, and.

.and means for feeding eyelets'to one of said ward-and in an approximately horizontal posistruction and arrangement of parts may be made-within the spirit and intendedscope of the invention.
