SPECIFICATION forming part of Letters Patent No. 714,336, dated November 25, 1902. Application filed .Tanuary 14, 1902. Serial No. 89.733. (No model.)

. To all whom it may concern:

` borough of Brooklyn, county of Kings, and

view of the same.

` vation.

city and State of New York, have invented certain n'ew and useful Improvements in Button-Setting Machines, of which the fol- `lowing is a specification.

This invention relates to the class of machinesemployed for setting buttons and the `like on fabrics, eyelets or hollow rivets being employed as securing devices.

In the machine herein illustrated and embodying the invention the buttons are placed In the accompanying drawings, Figure lis a front elevation of the machine, partly broken` away to disclose the perforatingplunger and spring; and Fig. 2 is a side ele- Fig. 3 is a side elevation similar to Fig. 2,l but showing the parts in the position of setting the button; and Fig. 4 is a front In Fig. 3 the work-bedis seenin section and the near column omitted, and in Fig. 4 the eyelet-box is omitted as unnecessary to the illustration. Fig. 5 is a detail section at m5 in Fig. 3, Aand Fig. 6 includes a plan view ofthe delivery end ofthe eyelet` track and of the button-pocket.

Only the head or upper part of the machine is herein illustrated, as this part oontains all of the novel features of theinven.-

tion. It will be sufficient to say that the frame 1 of the machine is supported on a suitable baseor pedestal of any kind, in which is mounted an operating-treadle coupled bya rod2 to the main lever 3of the machine.

The lever 43 is fulcrumed on the main frame at 4. It has adjustable Astops 5 and 6 to limit `its rocking movement and aretracting-spring 7.` This lever actuates the three operating parts of the machinenamely, the perforating-plunger, the clenching-plunger, and the shoulder 35 on the bracket 1" and has a stud eyelet trackand box.

The lever 3 carries a stud 8, which engages an L-shaped or angularslot 9 in the lowerbow-lever 10 has in it aslot which is engaged ,by a pendent arm 12 of a lever 12, fulcrumed at 13 on an overhanging arm 1' of the frame l. The lever 12 operates the perforating and clenching plunger 14. This plunger has a guide-bearing in the arm 1', and the front arm ofthe lever 12 engages a slot in the upper end of said plunger. The plunger 14 carries a perforating-point 15 and has a retracting-spring 16. (Seen in Fig. 1.)

The eyelet-box 17 is carried on the elevated end of an inclined track 18. This track is `mounted on a carriage 19, which -has lugs 20, `which have sliding bearing on a guide-rod 21, `Secured to the frame l. forked (see Fig. 5) to receive the slotted end of a rod 22, wherein the rod is coupled by a bolt or pin 23. The other end of the `rod 22 is coupled to the pendent end of a swinging link 24, and a link 25 couples the swinging link to the front arm of the lever 3.

At its lower delivery' end the eyelet-track .18 has a spring latch-stop 26 to prevent the eyelets 27 from escaping at this end. The latch is best seen in Fig. 6, and the eyelets are seen in Fig. 2, where the track is partly broken away to disclose them.

Mounted in a guide-bracket 1" on the main frame lis a sliding frame 28, in which is fixed an anvil 29. The frame 28 has at its lower part a cross-pin 30, which engages slotted jaws on the front arm of the main lever 3. The anvil 29 has in it a yielding pin 3l, which passes up through the eylet and retains it. Thispin 3l isl backed by a coilfspring in a bore inthe anvil 29, and it iscapable of being pressed down into the plunger by the per- .foratingpoint on the clenching-plunger above (with which it is alined) during the setting operation. The spring behind the pin 31 has not been illustrated, as it is not a new construction so far as this invention is concerned.

The work-bed 32 is supported on two columns 33, mounted in the sliding frame 2S.

One of the lugs 20 is These columns are free to slide in their bearings; but 'each is provided on its inner face with a cam-lever 34. This. lever bears on a IOO Fig. 3, wherein the column 33 and thelever 34 at the near side are omitted, so that the slot and the stud of the cam-lever may be seen clearly. The-cam-lever, however, is represented in dotted lines in its proper position. In the normal position of the parts, Fig. 2, the stud 36 occupies the laterally- .curved part of the cam-slot, and so holds the cam-lever in the inclined position (seen in Fig. 2;) but when the frame 28 moves upward the studs 36 are drawn into the straight parts of the cam-slots 37, thus turning the camlevers to the position indicated in Fig. 3, and thereby elevating the work-bed sufficiently to clamp the goods that may be resting thereon up to and against the button-pocket 38, which is secured to or forms a part of the arm 1.

It will now be advantageous to explain the operation of the parts as far as they have been described. A button having been placed in the pocket 38 and the goods or fabric placed on the workbed the operator depresses the treadle with his foot. This rocks the lever 3 and through it operates the three mechanisms already described, partly simultaneously and partly consecutively. As the rear arm of the lever 3 descends the stud 8 acts, through the intermediate lever and upper lever 12, to drive the perforating-point down through the fabric or goods, said point passing irst down through the aperture in the button in the pocket 38. After the stud 8 reaches the angle in the slot 9 the lever 3 continues to move down, but without operating further the perforating and clenching plunger. Simultaneously with the above movement the'lever 3 drives up the anvil 29 and the work-bed 32 by the means already described. In fact,the work-bed will move up and clamp the fabric even before the perforating-point acts. As the anvil rises the pin 36 will pass through the end eyelet in the track 18, after which the latter will be withdrawn, leaving the eyelet impaled on the pin 36. The slot in the coupling end of the rod 22 allows the pin 3l to move upward far enough to impale the eyelet before the rod 22 moves back the track. The eyelet is carried up, forced through the goods and the button, and clenched down thereon. When the parts are retracted, the attendant removes the button from the pocket by drawing out the goods and placing it in position to receive the next button.

In order that the button may be properly placed in the pocket 38, so that its center will be in the path of the perforating-point 15, even though the attendant be careless in inserting the button, an automatic placer is employed which will now be described with reference to Fig. 6 in addition to the principal views, this being a sectional plan view of the pocket and placer.

On the side of the arm 1 and close to the pocket is mounted an upright rock-shaft 39, which carries at its lower end a placer-arm 40, adapted when the shaft is rocked to bear on and push the lbutton back into the pocket. The shaft 39 has an offset upper end 39', which is cut away at one side, and a stud 41 on the clenching-plunger 14 strikes this offset portion of the shaft when the plunger descends and rocks the shaft, so as to cause the placer-arm thereon to push the button back into its place; When the plunger 14 rises, a spring 42 rocks the shaft back, so as to open the button-pocket.

The lugs 2O on the carriage 19 play close to the main frame, (see Fig. 5,) and thus prevent the carriage from rocking about the rod 21.

Preferably the work-bed will be supported on strong cushion-springs in the columns 33 in order that they may adapt themselves to materials or goods which vary slightly in thickness. These springs are indicated in dotted lines in Fig. l.

It will be noted, particularly by reference to Fig. 3, that when the clenching-plunger 14 is depressed the engagement of the stud 8 on the lever 3 with the lower arm or branch of the slot 9 locks the parts, so that the upward pressure of the anvil cannot drive the plunger 14 upward.

The eyelet-box 17 is provided with a brush which is rocked or oscillated by means of a link or rod 43, coupled at one end to the frame and at the other end to a crank on the brusharbor. This is a known device and is not claimed herein.

Having thus described my invention, I claim 1. A machine for the purpose specied, having a clenching and perforating plunger, means for operating same, a button-pocket fixed in position in the path of said plunger, a vibrating placer-arm at the pocket for placing the button, and means between the said arm and the plunger whereby the latter, in its descent, actuates the placer-arm.

2. A machine for the purpose specified, having a clenching and perforating plunger provided with a stud 41, a button-pocket 38, fixed in position in the path of said plunger, the upright rock-shaft 39, adjacent to the pocket and having an offset upper extremityy in the path of the stud 41, the retractingspring 42 of the said shaft, and the placerarm on said shaft and adapted to place the button properly in the pocket.

3. In a machine for the purpose specified, the combination with the frame, of the main lever fulcrumed on the same, the anvil and its carrying-frame, coupled to the said main lever, the perforating and clenching plunger, the intermediate lever 10, having an angular slot in one arm engaging a stud in the main lever, the said stud, and the lever 12, one arm of which engages a slot in the clenching-plunger and the other arm of which engages a slot or aperture in an arm of the intermediate lever, substantially as set forth.

4. In a machine for the purpose specified, the combination with the intermediate elbowleverlOffhaving slots in `its respective arms,

of` the lower lever 3, 'having `a stud engaging i the angular slot in one arm of said intermew bed carried by columns 33 mounted in said sliding frame, and the cam-levers 34 pivotally mounted on the respective columns and pro- 15 vided each with a stud 36 which engages one of the cam-grooves in the sliding frame, suhstantially as and for the purposes set forth.

In Witness whereof. I have hereunto signed my name, this 7th day of January, 1902, in zo the presence of two subscribing witnesses.
