llVlACHINE FOR MARKING AND CREASING SHOE-VAIVIPS.

SPECIFICATION forming part of Letters Patent No. 533,368, dated January 29, 1895.

Application filed August 29, l 893 To all whom. it may concern:

Be it known that I, ALONZO B. MGOOY, a citizen of the United States, residing at Burlington, in the county of Burlington and State of New Jersey, have invented a new and useful Machine for Creasing and Punching or Marking a Shoe-Vamp for Positioning the Toe-Tip Thereon, of which the following is a specification.

A reciprocating horizontal pressing-bar acts upon a properly supported folded shoe-vamp, and moves in unison with a downwardly projecting punch attached to it, so that said bar presses on the folded-vamp and the punch enters it at the same time, by which a crease is formed in the front or middle of the vamp, and two perforations or marks are made in its curved edges, -for centering and locating the toe-piece. Means are provided to cause the pressing-bar and punch to re-act after each creasing and punching in order to give space for the free insertion and removal of the vamp. Thus prepared the toe-tip can be sewed on the vamp without troubling the operator to guess at itsposition.

On reference to the accompanying sheet of drawings making part of this specification: Figure lis a side elevation of a machine embodying my invention. Fig. 2 is a plan view through the line 1 2, Fig. l. Fig. 3 is a ver` tical sectioned-view of the pressing bar when raised. Figli is a vertical sectioned-view of the pressing-bar in its down and :operative position. Fig. 5 is a longitudinal section of the pivoted guide-arm and graduated-plate,

Fig. 2. Fig. 6 is a plan view of a shoe-vamp before creasing and punching or marking. Fig. 7 is a folded view of a shoe-vamp after creasing and punching or marking. Fig. 8 is a spread-out or plan view of a shoe-vampwafter creasing and punching or marking; and Fig. 9 is a plan view of a shoe-vamp and its toetip sewed on. i

Similar letters refer to'similar parts in the several views.

A is the base of the machine, to which is fixed the upright or frame B.

C is a horizontal-shaft, in bearings of the Serial No. 484,341. (No model.)

frame, which is actuated by a pulley D in connection with any suitable clutch-device. 5o To the front end of said shaft is fixed a crank- Wheel or crank E, whose connecting-rod F engages with a loose-collar G on a vertical pressing-rod H, which reciprocates, and is su p ported and guided .in bearings, a, of the frame B.

I is an adjustable lifting-collar on the pressing rod H, above and in engagement with connecting-rod loose-collar G, andJ another and similar adjustable collar at a convenient dis- 6o tance below on said pressing-rod, the intervening space being occupied by an encirclingspringK,bearing endwi'se between the crankcollar G and the adj ustable-collar J. Said spring K connects the crank E and the pressing-rod H through the medium of the crankrod F and its loose-collar G, and is the means of converting the rotary motion of the crank into the downward right-line and pressingmotion of the pressing-rod. The -degree of 7o downward pressure of the pressing-rod depends upon the distance of the collarJ from the collar G, and the consequent elasticity of the spring K. rThe reaction and lifting of the pressing-rod H is caused by the collar G 75 acting upwardly against the collar I.

L is a horizontal vamp-creasing bar and punch adj ustably xed to the end of the pressing-rod H. It has an opening, b, at one end, for the reception of a vertical guide and 8o stay-pin, c, of the base A, and is provided with a depending-punch M for punching or marking the guide holes, d, Figs. 7, 8, and 9, in a folded shoe-vamp N. To the bottom of said bar L is fitted a throw-oft spring, f, Fig. .3, the 8 5 loose end, g, of which, rides over the end of the punch M, and throws the folded vamp from it on the reaction of the pressing-bar L after each creasing and punching.

P is a gage and vamp-guide on the base A, 9o Figs. 2 and 5, composed of an arm Q pivoted on a center, h, of the base, in connection with a graduated-arc R raised above and fixed to said base, through the slot of which passes a set-screw S, which being loosened permits the 95 arm to "be turned and adjusted as desired.

The loose end of said arm Q is b'ent to form a shoulder or bearing, 1', for the edge of the vamp-fold or crease, and thus insure the correct positioning of the folded-Vamp under the pressing bar.

On the application of power, the rotary motion of the crank E is imparted to thc loose-collar G, of the pressing-rod H, through the connecting-rod F. Said collar G acting on the adj ustable-collar I lifts the rod H. For a down-stroke the motion of the crank is imparted to the loose-collar G, thence to the spring K bearing on the adjustable collar J. The spring serves for an elastic connection and forces down the rod H and bar L with an elasticity consequent upon its degree of compression between thecollars, J, thereby adapting the machine to Vamps of Varying thicknesses without injury to the leather or material.

A Vamp N is made ready for creasing and punching or marking, by folding it evenly and equally, the bottom curved-edge, 7c, coinciding, and the top one, Z, likewise, Fig. 7, after which it is placed on the base A beneath the bar L when in its raised position, Figs. 2 and 3, care being taken to bear the end of the fold or crease in the bend, t', of the arm Q which has been previously adjusted in connection with its arc R for Vamps of that size. On the descent ot the pressingrod H its horizontal-barL operates by simultaneously pressing the Vamp-fold or crease, e, and punching or marking the double bottom-edge, 71;, at, d, for locating the position of the top and ends of the toe-piece O on said Vamp when open. The horizontal bar reacts after each creasing and punching or marking in order to give space for the free insertion and removal of the Vamps. Its elongation or extension both ways beyond its center permits the said pressing-bar L, to operate on Vamps of Varying sizes, one end or side of the bar doing the creasing, and the other the double punching or marking.

I claim- 1. In a machine of the character described, the combination of a reciprocating pressingrod, a collar of the pressing-rod for transmitting a downward motion to it through the medium of a crank, an end-confined encircling-spring of the pressing-rod on which said collar bears for imparting an elastic-pressure to said pressing-rod, a horizontal pressing-bar fixed to the end of the pressing-rod and extended both ways beyond its center, so that one end of it creases a folded-Vamp with an elastic pressure and the other end doublepunches or marks the folded-edge of said Vamp, and a collar of the pressing-rod for refVersing its motion, for the purpose shown and described.

2. In a machine of the character described, the combination of a reciprocating pressingrod, a collar of the pressing-rod for transmitting a downward motion to iti-through the medium of a crank, an end-confined encircling-spring ofthe pressing-rod on which said collar bears for imparting an elastic-pressure to said pressing-rod, a horizontal pressing-bar ,xed to the end of the pressing-rod and eX- tended both ways beyond its center so that one end of it creases a folded-Vamp with an elastic-pressure and the other end doublepunches or marks the folded edges of said vamp, a collar of the pressing-rod for reversing its motion, and a Vamp-guide on the base of the machine, for the purpose shown and described.

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