UNITED STATES PATENT OFFICE.
PHILIPP HURM, OF HAMILTON, OHIO.
Specification forming part of Letters Patellis No. 49,109, dated August 1, 1865.
To all whom t may concern:
Be itknown thatLPHILIPP HURM, ot'Hamilton, Butler county, Ohio, have invented a new and useful Wood-Bending Machine; and I do hereby declare the following to be a full, clear, and exact description thereof, reference beiughad to the accompanying drawings, making part of this specitication.
My invention relates to the class ot wood bending machines which are employed in the manufacture ot plow-handles, carriageshat'ts, and the like; and my invention consists in an arrangement of wedges, stirrups, and their accessories, for the more ready and eiectual clamping or locking ot' the back-strap.
Figures l and 2 are respectively a frontend a rear view ot' apparatus embodying my iinprovenrents. Fig. 3 shows a portion ot' the operative parts detached.
A is a block or form.
Bis a back-strap, its hooked rcarend eng |ging around a bar, O.
D is the back shear-bar, for holding the rear end of the strap and corresponding portion of the stuft' in position.
The form A is notched in front to receive a series of stirrups, E, perforated at their lower portions to receive a key, F, and at the upper portions to receive pins G. The stirrups E are held against vertical displacement by means ot' the said key F, and against lateral displacement by means ot the notched form A and of a shear-bar, I, secured to the front of the form by means of screw-bolts J.
The back-strap B terminates in front in a loop, K, to receive a wedge, L, by whichthe strap is secured to the strip M to be bent.
The strip having been bent down onto the frame N, one of the pins G, is inserted in the proper apertures of the stirrups and a Wedge.,
O, is driven under said pin G and operates to i structed and replaced, than thc customary ap` para-tus. i
It will be seen that by the loosening of `the shear-bar I and sliding out ofthe key F any i one of the stirrups may be removed and replaced by a new one.
I claim herein as new and ot' my invention- The former A, stirrups E, key F, shear-bars D I, bolt J, pins G, and wedges O, arranged and operating together substantially as described. if
In testimony of which invention I hereunto set my hand.
PHILIPP HURM.
