FREDERICK RICHARDSON, OF PROVIDENCE, RHODE ISLAND.

MACHINE FOR SECURING WEARING-PLATES TO RUBBER OVERSHOES.

SPECIFICATION forming part of Letters Patent No. 308,988, dated December 9, 1884:.

Application filed April 18, 1884. No model.)

To aZZ whom it may concern/.-

Be it known that I, FREDERICK RICHARD- soN, of the city and county of Providence, and State of Ithode Island, have invented certain new and useful Improvements in Machines for Securing; Wearing-Plates to Rubber Over shoes, ofwhich the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to that class of machines which are designed to secure wearingplates to the soles of rubber overshoes. These shoes are made without heels, and consequcntly wear very rapidly at the rear ends of the soles, so that the sole is soon perforated and admits water into the shoe, rendering the shoe useless- In order to prevent this rapid destruction of the shoe, metal wearing plates are secured to the shoe at the point of most rapid wear. These wearing-plates are formed with a body shaped to conform with the contour of the part to which they are attached, and are provided on their upper sides with pins or projections,which pass through the body of the rubber sole and are turned down at their upper ends, so as to clinch the sole.

To firmly secure the plates to the soles, it is necessary that all of the pins be forced simultaneouslythrough the rubber sole, and also perfectly clinched.

It is the object of my invention to produce a machine which shall perform these operations accurately and rapidly and with facility.

To the above ends my invention consists in the peculiar and novel construction and arrangement of the machine and certain of its auxiliaryattachments, as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which-- Figure l is a front view of my improved machine. Fig. 2 is a similar view of the same, showing mechanism for automatically turning the anvil. Fig. 3 is a side view of the structure shown in Fig. 2. Fig. i is a plan view of the clinching-(lie. Fig. 5 is a perspective View of the support for the shoe-toe. Fig. 6 is a plan view of the guide for the shoeheel. Fig. 7 is a side view of the wearingplate. ,Fig.8is a plan View of the same. Fig. 9is an edge view of the die. Fig. 10 is a plan view, partly in section, of the structure shown in Figs. 2 and 3.

In Figs. 7 and 8, A designates the wearingplate,which is of segmental form and provided on its upper side with a numberof pins or projections a,which are pointed at their up per ends, so as to readily penetrate the rubber, and also to facilitate the bending or clinching of the pins.

B is the base of the machine, and B is a curved bearing, upon which rests the post 0, which is secured to the hinged lever C. The lever O is provided with the handle 6 by means of which the lever may be readily moved inward and outward.

C designates the clinching-die, which is supported on the post (3.

D designates the rubber overshoe, the heel portion of which is supported by the post 0,

the die 0 of which lies within the shoe, and the toe of which is supported by the wire bracket d, which holds the toe in the proper position.

E designates a slide,which is supported by the handle 0", and is provided with the holder E, by which the shoe is held firmly on the die 0" by bearing, against the rear of the shoe. The heel-plate A is held in a recess formed in the lower end of the plunger F, or in a detachable member thereof, the lower end of the plunger or its detachable member being magnetized, so as to hold the heel-plate until it is firmly secured to the shoe. The plunger is operated by any suitable means-such as a cam and hand-lever, by foot-power, or by any of the well-known devices by which pressplungers are operated. The die 0 as shown, is formed on its upper side with a semicircular series of inclined or beveled surfaces, 0, and also with a plane semicircular surface, 0. The object of this construction of the die-face is to first bend the ends of the pins a by the I beveled surfaces 0 when the ends are driven through the rubber shoe-bottom, and then to clinch such ends by the plane surface 0, the penetration and preliminarybending of the pins being accomplished practically simultaneously by one stroke of the plunger when the shoe is interposed between the plunger and the beveled surface of the die, and the subsequent clinching of the points being accomplished by a second stroke of the plunger when the shoe is interposed between the plunger-face and the plane surface of the die.

In order to present first the beveled and then the plane face of the die beneath the plunger without removing the shoe, I mount the post 0 on a spindle, I), and I provide the anvil with a handle, 0 so that the anvil may be turned half around upon the spindle, and so move the die as to bring the beveled and plane surfaces alternately beneath the plunger.

In Figs. 2 and 3 I have shown an arrangement of connections betweenthe post and the plunger, whereby the movements of the plunger are caused to automatically rotate the anvil.

G designates a beveled gear, which is supported in suitable bearings upon the standard G. On its periphery this gear is provided with ratchet-teeth, with which a pawl hinged to the lever g engages. One end of the lever g is centered upon the axle of the beveled ratchet-gear, while the opposite end is jointed to a link, which is in turn secured to a bracket,

y, 011 the plunger. A beveled pinion upon the upper end of the vertical shaft 9 meshes with the beveled gear G, and the motion thus imparted to the vertical shaft is communicated to the post by means of a gear-pinion upon the lower end of the vertical shaft, which meshes with a gear-rim, upon the post. Thus it will be seen that at the first downward movement of the plunger it will act upon the beveled surface of the die. Then, as the plunger ascends for the second downward stroke, it will revolve the post half-way around, the, gears being so proportioned as to produce this half-revolution. After the plunger has made its second downstroke it is raised a second time, and this imparts a further half-revolution, whereby the beveled surface of the die is brought under the plunger, as before.

h designates a spring-latch mounted upon the arm 0, and which comes into engagement with a beveled arm, h, mounted on the standard G, when the arm 0 is swung to bring the post under the plunger, and thus enters between the teeth of the gear-rim and locks V the post in proper position, while the arm 0 is thrown out, whereby the anvil always returns beneath the plunger in the same position in which it left it. The beveled surfaces 0 of the die 0'' are oppositely disposed, as shown in Fig. 9, so as to bend the clinching-points a of the plate A in opposite directions, which prevents any twisting of the plate during the bending of the points. This twisting or slip of the plate is produced when the points are all bent in the same direction, and results in rupture of the shoe-bottom. The support (Z is of greater width at its outer than at its inner end, so as to adapt it to receive the toes of shoes of different sizes. In order to facilitate this action of the support, it is rendered adjustable vertically by means of a slotted plate, cl, which is secured to a standard, 6?, upon the base of the machine by a hand-clamp, cl. The slide E is secured adj ustablyupon the handle 0 by means of the thumb-nut e, which binds the extension e of the slide against the handle. The heel-support E is-formed of two divergent arms, 6 6", so as to receive and hold shoes of different sizes, and this action of the support is facilitated by the slide E, in which the support is mounted. The outward movement of the arm 0 is limited by the stop supon the bearing 13 on the base B.

I do not wish to be understood as confining myself to the precise arrangement of gearing shown for transmitting the reciprocatory movements of the plunger to the post and for converting such reciprocatory movements into rotary movements.

Having thus described myinvention, I claim 2. A die-p1ate having a semicircular plane portion and a semicircular recessed or grooved portion, substantially as and for the purposes described.

3. The combination,with the revolving post, of the support cl, the arm 0, having the handle 0 and the slide E, carrying the support E, all constructed and arranged substantially as specified. I

4. The combination, with the rotating post and the reciprocating plunger, of the gearing between the plunger and the post for converting the reciprocatory movements of the plunger into the rotary movements of the post, substantially as described. 1

5. The combination, with the support d, formed as described, of the slotted plate at, the standard (Z and the clamp (1 for the purposes specified.

6. The support d, formed larger at'its outer extremity and smaller at its inner extremity, for the purposes set forth.

In witness whereof I have hereunto set my hand.
