MACHINE FOR SECURING HEEL-PLATES TO RUBBER SHOES.

SPECIFICATION forming part of Letters Patent No. 296,624, dated April 8, 1884.

Application and October 1, 1883. (No model.)

To all whom it 12mg concern:

Be it known that I, FREDERICK BrennansoN, of the city and county of Providence, State of Rhode Island, have invented a new and useful Improvement in Machines for Securing Heel-Plates to Rubber Shoes; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to'the accompanying drawings, forming part of this specification.

Rubber overshoes require for the protection of the rear of the heel a metallic heel-plate, the securing of which in the proper manner and in the exact position required is, owing to the pliable, elastic nature of the shoes, an operation attended with considerable ditficulty. To present a neat, and finished appearance, these heel-plates must be secured so as to conform to the rearline of the heel, and also must be secured so that the center of the heel-plate is exactly in the center of the heel.

The object of this invention is to so construct a machine that an unskilled operator can secure such heel-pl ates to the rubber overshoe when, in the selling, they are desired, secure the same always in the proper and most sightly manner and in the required position, and to perform this operation so that the nails or pins are well clinched and in the most expeditious manner.

Theinvention consists in the peculiar and novel construction of the machine by which the rubber overshoe and the heel-plate are held and guided so as to be always in their proper relative positions and the heel-plate is forced upon and secured to the heel of the shoe, as will be more fully set forth hereinafter.

Figure l is a front view of my improved machine, showing a rubber overshoe secured in the same and a heel-plate held in the guide. Part of the plunger is shown in section. Fig. 2 is a plan view, partly in section, showing the horn or post on which the shoeis placed, as pivoted at one side of the machine, so that it can be moved out andin, as is indicated in broken lines. Fig. 3 is an enlarged view of the under side of the guide by which the heel-plate is held until the plunger has partly forced the nails or pins into the heel of the rubber shoe. Fig. 4: is a view of the camand the plunger by which the heel-plate is forced on and secured to the shoe by clinching the nails or. pins of v the heel-plate;

to rubberovershoes are provided with pins or nails formed in one piece with the metal wearing-surface. They form no .part of this present invention, but are described in a previous application, now on file in the Patent- Oflice.

In the drawings, A is the base of the machine, provided with the segmental extension in, on which the horn or post B is supported, and on which it can slide out-ward from the plunger. The post 13 forms part of, or is secured to, the plate b, which is pivoted at b, and has on the opposite end the standard 0, to the upper end of which the bed Dis secured, and on which the slide E, carrying the guide and holder F, is mounted, and by which the heel-plate is held in place. The post or horn B supports the detachable die If, and has the forwardly projecting bracket Z2 secured to it, by which the forward part of the shoe is supported.

The standard (3 forms a convenient handle for drawing the post and shoe inward and outward.

The guideFis hinged in the slide E, resting on a spring. The slide E is provided with the handle or knob e, to facilitate outward and inand the guide and holder F are in position, rests against the bell-crank lever e pivoted to the frame G, so that the short arm of the bell-crank lever e comes in contact with the plunger g at the end of the groove 9, and thus the slide E and with the same the guide and holder F are moved out of the way before the plunger 9 has pressed the heel-plate against the heel of the shoe. The plunger moves vertically in suitable slides formed in the frame G, and is held in place by the plate 72.. The plunger gis connected to the cam H bya strap entering a groove in the cam, as is shown in Fig. 4:, but may be connected with the same in any other suitable manner, so as to rise with the camH when thehand-lever Iis raised, and be depressed when the hand-lever is depressed. The handlever I is made of such length as will secure the necessary force to drive the nails or pins of the heel-plate through the material of the heel, properly clinch the nails or pins, and compress the material tightly around the nails or pins.

The guide and holder F is made with a segmental end, f, of such form that while the ward movements of the slide, and also with the adjustable arm e, which, when the slide heel-plate rests on the same the pins or nails bear against the forward edge of the same, as is shown in Fig. 3; and to insure the placing of the heel-plate exactly in the center of the guide and holder F, and thereby exactly central to the heel, the guide and holder F is provided with the double spring f, which, when the heel-plate is placed on the guide and holder, enters between the two central pins of the heel-plate, and thereby insures the central position of the same.

To allow the machine to be used for the various sizes of shoes and corresponding heelplates, the guides and holders F aremade interchangeable, as well as the dies b so that for any required size or number of shoe the required die and holder-guide are placed 011 the machine, and the arm 6 is adjusted on the slide E, so that the holder-guide will be withdrawn from underthe heel-plate before the same is pressed on the shoe.

The operation of the machine is as follows: Heel-plates being required to be secured to rubber overshoes, the die I) and holder-guide F, corresponding to the number or size of the shoes. are placed on the machine, the horn or post B, with the parts connected thereto, is

, drawn outward on the segmental projection a until arrested by the stop on the end of the proj ection a. The shoe is now placed on the horn or post, and with its heel bearing firmly on the die I), the front supported on a bracket, 12 A heel-plate is now placed on the holderguide F, so that the pins bear against the forward edge, and the spring f enters between the central pins. The whole is now moved inward under the plunger 9. The hand-lever I is drawn down, thus forcing the plunger, by means of the cam H, against the heelplate, and commencing to force the pins on the heel plate through the material. As soon as the plunger rests firmly on the heelplate, the short arm of the bell-crank lever e comes in contact with the plunger and draws the slide E, and with it the holder-guide F, outward from under the heel-plate, which is now forced against the heel of the shoe. The pins penetrating meet the surface of the die b and are turned over, so as to be clinched, and the pointsforeed into the material, when the whole is further compressed and held by the clinched pins. The hand-lever I is now raised, the plunger follows the cam H upward, the post or horn and the shoe are swung outward, the shoe removed, and the operation repeated. Heel-plates may thus be firmly and accurately secured to rubber shoes by any person; and to insure absolute certainty in placing the heel-plates on the shoes the holder-guide is provided on its under side with the pins or projections Z Z, which bear firmly against the rear and sides of the heel portion of the shoe, so that the heel-plate is always placed in the proper and exact relation required to secure the same in the proper manner to the shoe.
