4 Claims.

This invention relates to press machines used in the manufacture of shoes for ornamenting the upper by stamping, perforatingfor attaching thereto decorative studs or the like.

Machines of this type include in their construction a work holder in which the shoe upper or the vamp or other upper blanks are placed by the operator in carefully gauged position while the holder is drawn forwardly into a readily accessible loading or unloading position. The holder without obstruction includes a stripper plate and mask which the operator heretofore has been obliged to close upon the work in order to hold it in flat condition and against displacement. After closing the mask, the holder is pushed rearwardly to locate the work properly with respect to the operating instrumentalities of the machine. The head of the machine is then caused to descend and the perforating or ornamenting operation effected. Subsequently the holder must be again drawn forward by the operator, the mask lifted, and the ornamented upper removed from the holder.

In one aspect the present invention consists in a mask arranged to open and close automatically thus relieving the operator of two operations in each cycle of the machine, insuring proper closing of the mask, and so organizing the machine that when the holder is drawn forwardly to its work-receiving and delivering position the mask will have been already raised so that the upper may be immediately removed from the holder.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings in which:

Fig. 1 is a plan view of the holder showing the mask in closed position,

Fig. 2 is a similar view in sid elevation,

Fig. 3 is a view in longitudinal section showing the holder in its operative position in the machine,

Fig. 4 is a similar view showing the holder in its work-receiving position, and

Fig. 5 is a fragmentary sectional view of the stripper plate and mask showing a stud in setting position.

For purposes of illustration, the invention is shown as embodied in a machine of the general type disclosed in Letters Patent No. 1,681,033, August 14, 1928, Freeman, although it will be understood that my invention is in no sense limited to that or to any specific type of press machine.

In Figs. 3 and 4 a portion of the base I ll of the machine is shown, this being provided with horizontal guideways l2 for the holder, and also a portion of the reciprocatory plunger or head i i of the machine.

The holder itself, as shown in Figs. 1 and 2, comprises a slide plate or base plate l3 designed to move freely in the ways 12 from an outer or loading position to an inner position in line with and beneath the head H. In the plate I3 is set a series of dies I4 arranged in an ornamental pattern andeach having a cavity in its upper end shaped, in this instance, to hold a pronged stud in position for setting in a shoe upper. A thin stripper plate l5, perforated to permit free passage of the dies [4, is yieldingly mounted by encased springs II on th plate l3 at the level of the upper ends ofgthe dies I4. The stripper is provided with a loop-shaped handle l6 at its rear end bywhich the whole holder assembly may 'beco nveniently moved back and forth by the operator.

Secured to the under face of the stripper plate l5 at its inner end'is a transverse angle iron l8 carrying at either end hinges l9. Connected to these hinges above the stripper plate is a mask 2| which comprises a thin plate arranged to overlie andhold fiat an upper part placed on the stripper; The pintles of the hinges i9 are both surrounded by torsion springs 20 which act, when permitted to do so, to swing the mask 2| in counterclockwise direction into the upright position shown in Fig. 4. For convenience,

the mask is provided at its outer end with a loop-shaped handle 22 similar to that of the stripper plate. As herein shown, the mask 2i is provided with a series of up-setting dies 23 arranged to register with the dies l4 and to cooperate with them in clenching the prongs of an ornamental stud upon a vamp or other upper part presented on the stripper plate. For the purpose of locating the work, the stripper is provided with two pairs of transversely adjustable gauge bars 24. The base of the machine is provided with a positive stop 25 for the purpose of limiting the inward movement of the holder assembly and locating it properly beneath the reciprocating head I I of the machine.

In operation a vamp, for example, is placed on the stripper plate while the holder occupies its outer loading position as shown in Fig. 4, the mask 2| then occupying its upright position so that the surface of the stripper plate is entirely exposed and the work may be freely positioned thereon. When the machine is to be used for incated in Fig. 3. When this occurs, the stripper plate is depressed against the springs I1 and .the mask is forced downwardly so that the prongs of the studs penetrate the vamp and are engaged by the upsetting dies 23 and clenched. The head I I then moves upwardly to its initial position and the operator is free tomoye the holder assembly outwardly again to its position as shown in Fig. 4. In this movement the springs Zllswing the mask 2i upwardly as it is moved out of contact with the head H, and when this outward movement iscompleted, the mask againoccupies its upright position. -The ornamental vampmay then be removed and the machine is in readiness for a new cycle.

The holder has been described as-adapted for the operation of inserting ornamental studs, but it will be understood that it is also adapted for forming ornamental perforations in parts of uppers, and in this case the dies 14 would be replaced by punches and themask 2| would be-perforated for the passage of the punches which would either cut against a paper backing on the head H or cooperate with punching dies.

It will be understoodthat the mask requires no attention on -the part of the operator. It automaticallyassumes its open position when permitted to do so, fully exposing the face of the stripper whereon the work is to be positioned, and then is automatically closed by engaging the head I I when the holder is pushed inwardly into operative position.

Having thus disclosed my invention and described in detail an illustrative embodiment thereof, I claim as .new and desire to secure by Letters Patent:

1. In .a press machine having a base with a guideway. therein and ahead reciprocating at right angles to the guideway,.a work holder comprising a slideplate having a series of stud-hold ing recesses, a stripper carried by the slide plate, and a mask hinged to the stripper and having a series of clenching dies therein arranged to clench studs presented in the said recesses beneath the head of the machine.

2. In a press machine having a base with a guideway therein and a head reciprocating at right angles to the guideway, a work holder comprising a slid plate movable inwardly and outwardly in said guideway and having stud-holding recesses, a stud-clenching mask pivotally ..mounted adjacent to the inner end of the slide plate, and spring means normally maintaining the mask in elevated position and acting to lift the mask after it has been depressed by the head of the machine.

'3. In a press machine having a base with a guideway therein and a head mounted to reciprocate at right angles to the guideway, a work holder having a bottom plate slidable in the guideway, a spring stripper plate mounted thereon, a mask hinged to the stripper and arranged to flatten a shoe upper part thereon, and spring means for automatically swinging open the mask when the holder is moved outwardly to carry the mask out of contact with the head of the machine.

4. A work holder for use in a press machine having a base with a guideway and a reciprocatory head, saidholder comprising a slide plate shaped to slide horizontally in the guideway to and from a position beneath the head of the machine. a mask mounted in the inner end of the holder to swing about a horizontal axis, and spring means normally holding the mask in upright position in which it will contact with the said reciprocatory head when the 'holder is pushed into the machine and be closed downwardly by such contact during the inward movement of the holder.
