ATEN'r RUFUS H. DORN, OF PORT HENRY, NEW YORK.
Specification forming part of Letters Patent No. 123,158, dated January 30, 1872.
Specification describing a certain Improvement in Boot-Grimping Machines invented by RUFUS H. DORN, of Port Henry, in the county of Essex and State ot' New York.
The invention will rst be fully described and then clearly pointed out in the claim.
In the accompanying drawing, Figure l represents a side elevation ot' the machine. Fig, 2 is a top or plan view, and Fig. 3 is a vertical cross-section of Fig. l taken on the line y y.
Similar letters of reference indicate corre spending parts.
A is the bench, which is elevated on legs B to a convenient height, with a tlanged pulley, O, at each end. D is an endless chain which runs over the pulleys O C, as seen in Fig. l. E represents one or more metallic formers, attached to the chain in such a manner that they do not obstruct the movement of the chain over the pulleys, while they are attached iirinly thereto. F F are two jaws which are securely attached to the top of the bench A. They stand edgewise and a short distance apart. Attached to the insides of each of the jaws is a perforated steel plate, G; but between the jaws and these steel plates strips or pieces of rubber or other elastic material are placed, marked h, and seen in Fig. 2. The position of the plates is regulated by bolts and set-screws, as seen in the drawing. The leather to be crimped is placed upon the forming end J ot' the two jaws, and hanging therefrom to or near the top of the bench. K is a plate at the base ofthe former E. The elbow L ofthe former E corresponds nearly or quite in shape with the two forming ends J of the jaws. M is a crank (it may be a pulley) on the end of the driving-shaft, by means ot' which the chain is revolved around the pulleys O C by hand or other motive power. As the chain revolves the formers E are carried round with it, and when the former strikes the leather at J it carries it through between the steel plates oi' the jaws, stretching and crimping it as it is held by the friction between the plates. The slots N of the plates increase the friction on the leather, but the elasticity afforded by the rubber strips h prevents the tearing oi' the leather. At the base of the jaws there is a groove which admits the plate l( of the former E. The chain revolves with the former or formers with very little friction when not crimping the leather. One or more uppers ot' a boot may be crimped at each revolution ot' the chain.
I; do not limit or contiue myself to the precise form or arrangement of any of the parts described, as they may be varied in many ways without departing from my invention.
Having thus described my invention, l claim as new and desire to secure by Letters Patent- 1. The former E, one or more, in combination with the chain D and jaws F, as described.
2. The combination of the chain D, formers E, jaws F F, plates Gr G, and bench A, substantially as and for the purposes described.
RUFUS H. DORN.
