UNITED STATES PATENT OFFICE.

f EDWARD S. WRIGHT, OF NEW YORK, N. Y., AND EDWIN ALLEN, OF NEW- l ARK, N. J., ASSIGNORS TO EDWARD S. WRIGHT AND L. M. HILLS.

GUN-STOCK MACHINE.

Specification forming part of Letters Patent No. 40,665, dated November 17, 1863.

To a/ZZ whom, it may concern:

Beit known that we, EDWARD S. WRIGHT, ofthe city, county, and State of New York, and EDWIN ALLEN, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Gun- Stock Machines; and we do hereby declare the following to be a full,clear, and exact description of the construction and operation of the same, when taken in connection with the accompanying drawings and the letters of reference marked thereon, and which said drawings constitute part of this specification, and represent, inl Figure 1, an end view, and in Fig. 2a plan ofthe bed and frame.

Similar letters of reference indicate corresponding parts.

Our invention is designed for performing that part of the work upon a gun-stock commonly called profiling or forming the stock around the lock. Both sides of the stock are shaped alike. This work has heretofore been performed. with hand-tools, and requiring most skillful workmen for its proper performance. lly our invention both sides of the stoek are proiiled or wrought at the same time and with the strictest mechanical precision, and' by workmen of ordinary ability.

To enable others skilled in the use of machinery to make and use our machine, we will proceed to describe its construction and operation.

A is the bed-plate, supported upon legs B B. Above and below the bed-plate are arranged slides C and D, supported and sliding freely in proper guides, E. To each of these slides a spindle, F, carrying a cutter, is fixed in bearings a b, and made to revolve by the ap plication ot' a band to the pulleys G on the said spindles. Springs or equivalent devices are employed to draw the two slides toward each other,and the levers c and d, actuated by the cam-lever H and pressing upon pins e f in the slide, forcet-he slideapart-that is, the upper one up and the lower one down, as denoted in red, Fig. 1.

L is a table resting on ways M M, andarranged so that it may be moved .parallel to or at right angles with the ways. This movement may be given by any known device. Attached to the table, on its upper side, is the former N, constructed with a groove the form of the cut to be made. In this groove the guide-pen i is set, and the movement of the table is guided thereby.

To operate our machine, the cutter when at rest being in the position denoted in red,Fig. 1, place the stock to be wrought upon the table and clamp it gijrmly thereon by any known device. Drop the lever H and allow the cutter (power having been previously applied) to come together, as shown in black, Fig. 1. Now move the table parallel to (r at right angles with the ways, as the natuie of the case may require, guided by the pin t' and former N, until the profile has bei-n dressed. The two cutters, working together, dress both sides at the same time. completed, raise the lever H to separate the cutters, remove the stock and introduce a second for the same operation, and so on. Thus `we easily perform the most difficult part of the labor upon the stock with mechanical ac curacy and in much less time than has heretofore been employed for the same operation.

Having thus fully described our invention,

what we claim as new and useful, and desire to secure by Letters Patent, is-

Two vertical cutters, working upon opposite sides of the stock, in combination with a table and former, substantially as herein set forth.

EDWARD S. WRIGHT.

EDWIN ALLEN.
