, Application filed October 31, 1918. Serial No. 260,429.

To all whom it may concern Be it known that 1, Lewis T. Rowe, a citizen of the United States, residing at State of Ohio, have invented a certain new and useful Toe-Plate Press, of

which the following is a full, clear, and

exact description.

This invention relates to machines for attaching protecting plates to the soles of boots and shoes. i

a The chief object of the present invention is to provide a machinewhich is particularly adapted for applying protecting plates to the toe portion of the soles of shoes in such a manner that the plate can be located upon. the sole in correct relation to the toe and can be quickly and securely fastened therc f Other and further objects of this invention will be apparent from the following description of a preferred embodiment thereof, reference being made to the accoin panying drawing.

in the drawing Fig 1. is a front elevation of the toe plate press including the present invention;

Fig, 2 is a side elevation, the hand lever being broken away;

Fig. 3 is a bottom plan view, on an enlarged scale, of the plunger showing the toe plate in position; and i Fig. 4e is a side view of the toe plate which may be -applied to a, shoe by means of the present lnventlon. a a

Referring to the draw1ngs,20 isthe base Lever 23 is provided with a cylindrical surface 24 which engages with thenotched upper end 25 ofa plunger 26, which is slid ably mounted in a bearing formed in the post21. Plunger 26 is provided with a notch 27 which is engagedby theloop 28 of a spring. 29, having intermediate portions thereofcoiled around studs 30 and 31, which are fixed upon post 21, and the end portions thereof coiled around studs 32 and 33 which are also fixed uponpost 21. f y

The lower or driving surface of the plunger 26 is provided with a recess 35 which is shaped to conform with the edges of the toe plate 50. Theplunger 26 is provided'with a groove 36 in which a leaf spring 37 is secured by means of screw 38. Spring 37 eX- and the upper surface of the last {t0 upon which the sole of the shoe rests is downwardly inclined rearwardly of the toe portion4-2 at an angle of approxlmately five degrees.

The operation of the toeplate press, is as 3 follows i A shoe 60, indicated by dot and dash lines, is placed on the last 40in the position shown in Fig. 1, and with one hand pressing rearwardly, against the heel of the shoe, the operator forces the lever 23 downwardly, thereby causing the plunger 26 carrying the plate 50 to descend upon the toe portion of the sole of the shoe. The prongs 51, of the plate 50pierce the sole and are clinched baclr upon the inside thereof. The lever 23 is released, and the spring 29 causes theplunger 26 and lever 23 to ascend. Upward movement of the lever 23 is limited by a stop 23, formed on said lever 23, which cooperates with the post 21. i i

In order to insure the secure attachment of the plate to the sole, the upper surface of the last is inclined in the nni-i'uier de scribed so as to bring the tip of the toe portion at an elevation above other parts of the. underside or foot side of the sole when the sole is placed on the last. This arrangement is neccssary,since generally shoes are in a Worn condition before being. brought in by their wearer for the application of the toe plates. When in this condition, the sole of a shoe has been bevelled off at the tip of the toe portion due to the scraping of the sole onthe pavement. To apply toe plates to shoes in this condition, a press having a lastparallel to the bottom surface of the plunger for driving on the toe plate cannot be used since the front prong of the plate will not be; securely fastened to the sole. Butbyshaping the last'in the manner described and illustrated,this difficulty is overcome, and each prong of the plate will function properly to securely fasten the plate upon the sole. Y

When a shoe sole becomes worn off at the toe portion, a more or less well defined ridge or junction line is formed showing where the worn surface of the toe portion joins the much less worn or normal portion of the sole. The five-degree angle of inclination of the last has been chosen, because, in the vast majority of cases, when a. shoe worn down at the toe is placed in inverted portion over the last, this ridge or junction line will be substantially in a-line'ment with the plunger 26 and will be located above other parts of the outside of the sole. As a result of this, when the plunger descends carrying with it the plate 50, plate 50 will contact first with this ridge line and the heel of the plate will extend over the normal portion of the sole while the toeof plate 50 worn toe portion of the when the full pressure is the prongs 51 of the plate 50 back upon the under side of the sole, the portion of the sole adj acent this ridge line will be compressed more than any other portion. Now when the pressure of plunger 26 is relieved, this more highly compressed portion will tend to expand to its original thickness with greater force than the portions of the sole covered by plate 50 which has been com pressed to a lesser degree. The result of this is that when the pressure of plunger 26 is relieved, the plate 50 will bow outwardly slightly and the prongs 51 will tend to grip the sole more firmly.

Another advantage resulting rearward declination of the last surface is that the shoe will not slip on the last when pressure is applied by the plunger 26. The shoe is moved as far back on the last as it will go before the plunger is caused to descend. If the plunger causes the shoe to shift on the last at all, this shifting would tend to occur in a rearward direction; but such motion is prevented because the toe of the last acts as a. stop for the inside of the toe of the shoe.

WVhile the device described constitutes a preferred embodiment of the present invention, it is to be understood that other forms or embodiments might be adopted, all coming within the scope of the claims which follow.

I claim:

1. In a toe plate press, the combination with a movable element having a driving surface for driving a toe plate on the sole of a shoe, of means forsupporting the shoe with the sole thereof in a plane inclined with respect to the driving surface of the movable element, the underside of the toe of the sole being located nearer to the driving surface than other portions of the 'foot side of the sole when the shoe is placed sole. Obviously, applied to clinch from the extends over the in inverted position over the supporting means.

In a toe plate press, the combination with shoe holding moans oi toe plate holding means, one of said means being movable relatively to the other, said shoe holding means having provisions for supporting the shoe with the sole thereof in a plane inclined to the plane oi, the toe plate holding means with the underside of the toe portion oi the sole located nearer to said last named means than other portions of the foot side of the sole when the shoe is placed in iiwerted position over the supporting means.

3. In a toe plate press, the combination with a. movable plunger havin a driving surface at one end thereof, or a last for supporting the sole ol the shoe, said last having the toe portion thereof in alignment: with the driving surface oi the plunger, and having the sole supporting surface inclined to the plane of the driving surface of: the plunger, the said toe portion of the last being located nearest said driving surface.

4. In a toe plate press, the combination with a plunger ha *ing a driving snrt'ace and means to retain a toe plate temporarily thereon; of a last for supporting the sole ol a shoe, the sole supporting surface of the last being rearwardly downwardly inclined from the toe portion thereof at such an angle that the ridge portion of a worn sole ormcd by the junction of the worn toe pori n with the normal sole portion will be located nearest to the driving surface.

5. In a toe plate press. the combination with a piun; r having a driving surl ce and menus to retain a toe plate tenngorarily thereon; of a last tor supporting the sole of a shoe, the

solo supuorting surface of the last being rearwardly downwardly inclined "from the toe portion thereof ap 'n'oximatcly at an angle of live den ces so that the ridge portion of a worn role formed by the junction oi the worn toe portion with the normal sole portion will be located nearest to the driving surface.

6. In a toe plate press, the combination with a. frame supporting a last and a vertically disposed bearing; of a plunger slidablv mounted Li said bearing and having toe clip retaining means at its lower end, a notched upper end, and a transverse notch intermediate its ends; a lever pivoted upon said frame and engaging the notched end of said plunger; and a loop spring engaging said transverse notch to restrain downward movement of said plunger.

In testimony whereof I allix my signature.
