BUTTON-FASTENING MACHINE.

SPECIFICATION forming part of Letters Patent No. 665,211, dated January 1, 1901.

' Application filed March 23, 1898. Serial No. 674.914. (N model.)

To all whom it may concern:

Be it known that I, EDWARD ALEXANDER GRIFFITH, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Button Fastening Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in button-setting machines which are either hand or foot operated, and the buttons and fasteners are put in position by hand ready for fastening, the machine being known as a button-fastener; and the objects of my improvements are, first, the proper holding of the button before, during, and after the fastening, and, second, the proper holding of the fastener before, during, and after the fassomewhat shortened in height. Fig. 2 is a plan view of the same. Fig. 3 is a vertical view of my entire machine, taken at right angles to the view shown in Fig. 1. Fig. 4 is an enlarged plan view of the chuck for holding the button, with its shank shown in section. Fig. 5 is an enlarged plan view of the chuck for holding the fastener, with the jaws closed. Fig. 6 is an enlarged plan view of the anvil upon which the fastener is placed.

Similar numerals refer to similar parts throughout the several views.

1 is the main frame of the machine, .in which is journaled operating-lever 2 in journals 6, one end of which lever is handle 3, the other end 4 of which forms teeth for engaging with the teeth 9 of operating-cam 5. Near journal 6 of operating-lever 2 is tooth or cam 7 for operating tooth 8 of operating-cam 5.

10 is a screw-stop for limiting the movement of operating-lever 2 and is set into main frame 1.

11 is a recess in main frame 1, in which operates rack-plunger 12. On the side of rackplunger 12 is rack 13, which meshes with teeth 14 of operating-cam 5. At the lower end of rack-plunger 12 is inserted setting-die 15,.

which is held in place by set-screw 16. On the side of rack-plunger 12, at its lower extremity, is hollow sleeve 17, inside .of which slides shank 18, attached to'the lower part 19 of the button-chuck, said shank 18 being prevented from rotary motion by guide 20, working in guideway 21 in main frame 1.

22 is the upper part of the button-chuck, which operates inside of sleeve 17 and is prevented from rotary motion by guide working in guideway 21 in main frame 1.

17 is a sleeve surrounding sleeve 17. Between sleeve 17 and shank 18 is spring 23.

23 is a spring for pressing upper part 22 of the button-chuck to the lower part 19 of the button-chuck. Between. these two parts is placed an oblong-shank button 20 (shown in Fig. 4) to be operated upon, the groove in the lower part fitting the oblong shank of the button,thus holding the button securely in proper position for fastening.

24 is the anvil or chuck, upon which is placed the fastener 31, which is held in place by jaws 25, which jaws are pivoted to anvil 24 by pivots 26. To each jaw is attached handle 27 for operating the same with fingers.

28 is a spring tending to keep the jaws closed. Anvil 24: is secured to main frame 1 by set-screws. (Not shown.)

29 represents openings in the jaws, which embrace the prongs of the fastener, each opening being sufficiently large to admit the prongs of the fastener in each jaw, the other registering therewith being plain, thus setting the fastener slightly on the skew to enable the prongs to clench past each other.

32 is a slot in rack-plunger 12, in which Works pin-screw 33, secured in main frame 1,

spring 34 is secured at one end in a hole 35 in screw journal-plug 36,which contains journal 6. The screw journal-plug 36 is afterbeing screwed into position secured by set-screw 37. Spring 34 after leaving hole 35 is bent into a coil until it emerges from the inner end of recess 38, when it then takes a long loop under lever 2, and the other end is formed and secured on the other side of the machine similar to the method above described.

When I wish to use the machine as a footpower fastener, I mount it on a suitable stand 39, having base 40. On base 40 is fulcrumed foot-lever 41 by means of pin 42. At 43 on foot-lever 11 is one end of link 44., the other end of which is pivotally secured to lever 2.

4:5 is a spring tending to keep foot-lever 41 up, thereby keeping the machine open.

The operation of my machine is as follows: Jaws 25 are opened by means of alever-handle 2'7 with the fingers, and a fastener is placed on anvil 24. The jaws are then allowed to close, embracing the prongs of the fastener in openings 29. The oblong shank of the button is inserted in the slot in the lower part 19 of the button-chuck, the upper part 22 coming down and resting on the button, thereby clamping it between the two parts. The garment to which the button is to be secured is placed over the prongs of the fastener, and the die 15 is then forced downward, carrying with it the button-chuck, which brings up on the garment and slides in and on sleeves 17 and 17. The die continuing forces the garment and button over the prongs of the fastener and in so doing forces the jaws 25 open and out of the way by means of the shape of their edges, which are chamfered on their meeting edges, as shown in Fig. 6, and clenches the prongs of the fastener as they come through the button, continuing this process until the die, button, garment,fastener, and anvil bring up rigidly together,a rigid fastening being thereby secured. If I do not proceed so far, a less rigid fastening may be had. This I regulate by means of screw-stop 10.

If the setting-die 15 should stick in the button and on releasing operating-lever 2 should carry the button, button-chuck, garment, and fastener up with it, the shank 18 of the lower part 19 of the button-chuck would bring up against operating-cam 5, which would then perform the function, so far as shank 18 is concerned, of a stop, as shown in Fig. 6, before rack-plunger 12, in which is inserted setting-die 15, reaches the upper end ofits stroke, thus forcing the button-chuck and the setting-die apart.

The purpose of cams 7 8 is to increase the power of the machine at the time of clenching the fastener. The clenching-die when operated by said cams compared with handle 3 has a much slower motion than when operated by teeth 4 9. I

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a button-setting machine the combination of a button-chuck for holding a button, consisting of a bifurcated lower body between the jaws of which fits a button, a bifurcated upper body the jaws of which rest on and hold the said button in position, means tending to keep the two said bodies together, with a fastener-ch uck for holding a fastener, and means for bringing the said button and said fastener together and securing the same, substantially as described.

2. In a button-setting machine the combination of a button-chuck for holding a button, consisting of a lower body in which fits a button, an upper body resting on and holding the said button in position, means tending to keep the two said bodies together, the said button-chuck being so mounted that it can have but one motion and that a right line motion in line with the prongs of the fastener which is to be secured to the said button, and having means to prevent a rotary motion thereof, with a fastener-chuck for holding a fastener and means for bringing the said button and said fasten er together and securing the Same, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD ALEXANDER GRIFFITH.
