SPECIFICATION forming part of Letters Patent No. 278,012, dated May 22, 1883,

' Application filed February 7, 1883. (N0 model.)

To all whom it may concern:

Be it known that I, IVM. M. HAZEL, of New York, in the county of New York, and in the State of New York, have invented certain new and usefulImprovements in Setting-Instruments for Attaching Buttons to Shoes. and other Articles of Apparel; and I do hereby declarethat the following is a full, clear, and exact description thereof.

Myinvention relates to that. class of settinginstruments which are designed to be used for the attachment of buttons having metal eyes, by means of metallic fasteners, to various articles of apparel; and it consists in certain peculiarities of construction, as will be more fully set forth hereinafter.

In the drawings, Figure 1 is a. representation in perspective of my entire device. Fig. 2 is a perspective view of the under side of the hpper jaw. Fig, 3 is a like view of the spring. Fig. 4 is a like view of the upper side of the upper-jaw, partially broken away, and showing button and fastener in place, all ready to be .secured to the leather or fabric. Fig. 5is a longitudinal section of said upperjaw. Figs. 6 and 7 represent dies adapted for attachment to the lower jaw. Fig.8 represents a buttonfastener adapted for use in connection with my machine, and Fig. 9 represents the same fastener having button attached and clinched to the leather or fabric by my machine.

A represents the upperjaw of my machine, and A the lower jaw, each having the handles a and a, respectively crossing each other and secured together in the usual manner. The jaw A is formed with straight sides I) I), between which the top of the jaw is coneaved or rounded out from front to rear, while the lower or operative face of said jaw is flat at the center, as at c, with front and rear bevels, c and 0 respectively. These flat surfaces are of substantially equal extent, and the said face or lower part of thejaw A is slotted at 0 from the front end backward, the said slot extending through the beveled part c and about half-way through the part c.

. Bis a metallic spring, of the shape most clearly shown in Fig. 3, which has a slot, b, corresponding exactly to the slot 0, and the said spring is secured to the upper part of the I jaw in its concavity, as clearly shown in Fig. 4. The lower jaw, A, has a. flat upper face, d,

provided with a transverse groove having pref- I), as shown, and tempered, it' desired. I then preferably magnetize this die-I), and also magnetize the operative face of the upper jaw, A.

This increases the holding capacity of my device when employing iron fasteners, and to insure the successful operation of my spring B, in view of said magnetism, I preferably make this spring of tempered bra ss. My die is of peculiar construction, and consists, in its preferred form, 6 5 of a base having straight sides and bottom, while its ends 0 arise to exactly the height of the face (1 of the lower jaw, A, when the die is in place, so as to bethen perfectly level therewith, and it is provided with a. central rounded 7o ridge, f, midway between the ends 0 e, while between all these upward projections are the recesses g g, In Fig. 6, l have shown theserecesses with flat bases, and with the inner faces 50f the end projections, c e, beveled ,to meet. 7

said bases. \vhile' lll Fig. 7 I have shown the :inner faces of the said end projections, 00, rounded to meet the flat bases of recesses g g,

instead of inclining at an angle of about fortyfive degrees, as, in the preceding view; but either form of die may be used, as preferred.

My springB,initsnormalposition,lieswithin the recessed upper jaw, between its straight inner sides, I) b,withits longest portion horizontal, or nearly so, and its extreme end resting on the front end of the said jaw, so that. the two slots band G coincide at that point, leaving a considerablespace beneath the said portion of the spring, as bestshown in Fig. 5; but I when a fastener is attached to the eye of a button and the said eyeis slipped into the slots the spring 3 is pulled down onto the bottom of the concave recess, as shown in Fig. 4, and the fastener (the top of which rests against the under side of slot 0, where the metal is somewhat rounded out to receive it) isthus securely held by, the force of the spring, (aided by the magnetized condition of the jaw, already referred to in the case of iron fastcners,)withits prongs in position to straddle the rounded 10o ridge f of the die D in the lower jaw. The leather or fabric being now placed above the lower jaw and pressure exerted, the prongs of the fastener pierceithe fabric, and as the ends of the prongs strike the flat recesses g 9 they slide outward or apart till they reach the inclined inner faces of the end projections, e 0, whereby their points are inclined upwardinto the fabric, as shown in Fig. 9. The rounded ridgef serves to press that portion of the fabric or material between the prongs up into the loop ofthe fastener, and thus the eye of the button will be wholly above the surface of the fabric when the operation of clinching is concluded.

By reason of making the operative face of. the upper jaw beveled, as shown, greater direct pressure can be brought upon that portion of the fabric when the fastener is to be clinched, while the said fabric on either side of the portion receiving the fastener is not subjected to pressure, as would be the case were the face of the upper jaw all substantially flat, while by making the recess in said jaw concave at its base the button, with fastener attached, when slipped within the slots in jawand spring, will more securely remain in proper position for penetrating and clinching than it the recess were of other formation, the outer end of the jaw being higher than the base of the recess atits center, (where the button rests, the spring being forced down upon the base of the recess all its distance, as explained,) and thus guarding against the button slipping out or becomingaccidentally displaced during the operation of clinchin Again, by reason of the magnetization already referred to, fewer parts are necessary in holding a two-pronged iron fastener in an upright position than without such treatment of the upper jaw and die, the said fastener being held by magnetic attraction in the position in which it is originally placed until the positive pressure of the machine changes the position of its prongs in the pro- .eess of clinching.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 4 1. In a setting-instrument, the upper jaw provided with a concave recess, and slotted, as described, in combination with a metallic slotted spring, and with an operative lower face flat at its center and beveled at front and rear, substantially as set forth.

2. In a setting-instrument, the upper jaw magnetized on its loweroperativefacefln combination with the lower jaw provided with a clinching die, substantially as set forth.

3. In a setting-instrument, the combination of the upper jaw havingan operative'lower face, flat at its center and beveled -at front and rear, with the lower jaw provided with a clinching-die magnetized on its bearing-surface, sub stantially as set forth.

4. In a setting-iustrument, the combination of the lower jaw, provided with a transverse groove having straight sides and bottom,with a clinching-die having operative projections rising to the level of the face of said jaw, and a seeming-plate at right angles to the die and integral therewith, substantially asset forth.

5. In a setting-instrument, the combination of the grooved lower jaw with a clinching-die having upward end extensions, with flat tops and inclined inner faces, a central rounded ridge, and recesses with fiat bases between the central ridge and the end extensions, substantially as set forth.

6. In a setting-instrumerit, the upper jaw provided with an operative lower face, flat at its center and beveled at front and rear, substantially as set forth.

In testimony thatlclaim the foregoinglhave hereunto set my hand, on this (jth day of February, 1883, in the presence of two witnesses.

WM. M. HAZEL.
