SPECIFICATION.

T0 ALL WHOM IT MAYl CONOERN: v

Be it known that JOHN Gr. PUSEY, of the city, county, and State of New York, did invent, make, and

:use a certain new and useful Improvement in Carving and Drilling Machinery for Gun Stocks, 85e.; and the following is declared to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a side elevation of the said machine. Figure 2 is an end view. Figure 3 is a plan, with part of the head of cutters removed; and Figure 4 is an inverted plan of the holder for the pattern and gun stock. Similar marks of reference designate the saine parts.v

i The nature of the said invention consists in a reversible holder, carrying the pattern and gun stock or other article to be mortised, bored, o r carved, so that the gun stock can be carved to vreceive the barrel,A breechtang, and other parts on the top of the stock, and thenl turned over with the pattern and slotted or inlet to receive the ramrod, the trigger-plate, guard, zc.; and in consequence ofthe metal pattern and gun stock being firmly held in the said reversible holder, the -various slots must he exactly on line with each other in the gun stock, and there is no risk of the parts not coming exactly to place, because the present mode ofdetaching the stock after oneside has been cut, and then cutting the other Sido at a separate operation, is dispensed with, and 'the stock is held in place until cut all around in one direction, either on the top and bottom sides of the stock, or on the right and left sid'es of the stock, according to the way it is introduced inthe holder. This invention also relates, to the mode of holding the, cutters and 'guide in a parallel moving head that can be raised or loweredor'moved to the right or left with little or no friction. 'A head is also provided foi-,holding the cutters so as to present any particular one to the work to he performed, and the guide to `the particular pattern that is followed in mo'rtising, boring, or carving gun stocks or other articles.

In the drawing, a is thebed-plate of the machine; b [1 are vertical` frames, earryingial'i upright shaft, c, with a pulley, d, 'driven by competent power; e e c' e are arms ,jointed at one ond at I 1 to the vertical shafts ff, that are sustained at their ends by the centre-screws 2 2 entering the ends of said shafts, or any other suitable bearing may be used. These arms, le a', are parallel to each other, and their outer ends are connected by universal joints to the plate g, carrying thehead of cutters. The said universal joints are formed by the ends of the arms entering mortises in the vertical shafts 3 3, and attached thereto, and moving on pins 4, while said shafts, 3 3, are attached to the plate by centre-screws 5 5. It will now be understood that lthe plate g can he moved across thc bed a, or be raised up or down, and that the arms c c 0^ c preserve the same parallel to its` normal position, and thatfther'e is but little friction in moving the plate g and the cutter and guide in either direction. The weight of these arms and plate, and parts carried by thein, is sustained by springs L e, or counterbalaneo weights might be provided,'it` desired. This plateg carries avcircular head 7c of cuttingor carving tools. This circular plate cy has a ilangcd edge kept4 t0 the plate y bythe overhanging edges of the plates lc', which, however, allow this plate c to be revolved either by hand or by power, and stopped at any desired point. There isrepresented a pin, 6to be pressed into a h'ole in the edge of this plate k, to retain the same in position when turned to bring any of the particular cutters into place for action. 0n thi-s circular head lo are mounted any desired number of radiating stocks, Z Z, carryingcutters or tools o o. There are sh'own eight such stocks and tools, but the number might be greatcror less. The interior of the head c is open, Aand 4in this the pulleys n n of the respective stocks stand. mis a pulley set on an arbor or gudgeon attached to the harp that is afiixed to the hack of the plate g, and p isa slide and fork by which the belt d', from the pulleyd, can he slipped of of m on one of the pulleys u, or the reverse. When the said bolt is running on the Apulley m, the circular head 7c, cutter, stocks, and pulleys can be revolved, andwhcn the particular tool required is brought vertically below m, the pin 6 is slipped in to hold the circular plate c, and then the belt d slipped down upon the pulley below to drive the cutter connected to said pulley, while all the other pulleys are stationary. By the side of each tool is a tracer, q, ofthe size and shape of the tool inits revolution, so that said trai-cr applied to the pattern to be worked from, regulates the action of the tool in theusual mannerf The harp is extended out and terminates with a handle vertically above tho tracer q, and thc operator, by this handle, causes the tracer to follow the pattern as-hc moves the entire head of cutters up or down or crosswise of the bed ajand by giving to the article-to be operated upon, together with the pattern, an end motion along the bed a; the whole surface of thc article to beslotted,.mortiscd, or carved, can-be'brought to theaction of. the cutters, and one cutter can be carried out of action, and another brought into-position very speedily; thereby any usual cutter that Vmay from time to time be required for particular work can be brought into action, and the` cumbersome arrangement heretofore in use of a double slide to each cutter stock is avoided'. In place ofthe pulleys n n, a clutch might be provided near the end of Z, and the pulley m might have a slight play, so as to connect with said clutch on Z,- and rotate the stock and tool attached. llt willbe evident that the freedom with which the whole cutter-head moves on and with the parallel arms e e c e', greatly facilitates the carving or cutting operations, because the' attendant can cause the tracer to follow the pattern much more easily than the same movements could. be obtained if the cutter-head were mounted on a double slide on a stationary frame.

4'The cutter and tracer are free to move transversely or vertically with but little friction, and hence anbe moved,

to follow the most delicate pattern, and in all positions the cutter and tracer occupy the same position relatively to the pattern and the article being ca-rved.- In order to prcsent'the article tobe carved, bored, or mortised, to the tool,a frame r is madeuse of, fitted to slide on the bed-plate a, and the same is to be moved bythe pinion 7 taking the rack 8; saidpinion being turned by the crank 9, or any other suitable device. Within this frame fthe pattern is held, and also the piece of wood to be operated upon. In the drawing a gun stock sand pattern tare shown. These are to beef any desired size and character, and the pattern t is to be of metal, with all the mortises, grooves, ttc., required for receiving the parts of the. gun as usual. This metal pattern is held in the holder frame u that is attached by the centre pins 10 10 to the frame i'. rlhis holder frame u is constructed to i'it the opening in the frame c' s'o 'ras to be steady therein; but it can be swung entirely over, or rotated on the said pins 10 10. In this holder frame the gun stock s is introduced in the proper position relatively to the pattern t, andl clamped'irmly in place by a screw at 1l, or any other convenient mechanisml whereby said stock is rigidly sccur'ed'in place. The distance between the centres of the stock and pattern is to be the same as that betweenv the cutter or tool o andthe tracer g. It will now be Aseen that the upper side of the stock can be carved or inlet corresponding tothe pattern by bringing the proper tools into action,rand then the stock and pattern can be reversed with the holder u, and the parts out out on the under side of the stock, and,

by these means the stock andvpattern must correspond exactly, because their relative position is not disturbed until all the mortises, holes, de., are for1ned,.both above and below the sto-ck. In cutting along the curved part of the stock to receive the brcecli-ta1ig, or in cutting to receive thc guard and trigger-plate on the curved under side of the stock, the said surface is to be kept at rightanglcs to the axis`of the cutting tool (in order that said tool may leave the inlet. surface smooth and even) by turning the holder frame on its centres 10 10 as the cutting progresses. This may be donc by'a slot 12 in the side of the holder u-receiving astationary pin 13, which turns the said holder u, stock s, and pattern t, as the frame r is moved along the bed a. It will, however, be apparent-that a link connected to a fixed point might be employed to give the same movement. For morltising the side of the stock to receive the loch-plate and other parts, both the stock and pattern have to be entered at right angles to their present position. In this machine the pattern andiaiticle vto be carved are Iconn'cctcd together, and revolved or turned over in planes parallel to'cachother, and at right angles to the trunnions or centres. l v

The mounting the gun stock upon centres or bearings at or near its ends is not clai1ned;. neither is 'a series of tools fitted to move in slides, and brought into actionsuccess-ivcly. i i

What is claimed, and to bc secured byl Letters Patent, is i 1. Arranging a serios of tool stocks to radiate from a common centre, in combination with a series of tracers,substantially as specified, whereby allthc tools und tracers may be moved together in mortising, borino' .or-carving, but the tools not in use will, by their divergence, bc out of the way, as set forth.

2. The arrangement of the pulley m in the middle of the circular head cand ofl the fork p', oroits equivalent, vfor receiving and ehai'zgingthe'belt d', in the manner set forth.

3. 'lhe parallel bars, c e', cach jointed at one end by a universal joint toa fixed support, and at the other -cnd to a movable head, in combination with a cutter anda guide'or tracer, substantially as specified, whereby the lsaid lcutter and tracer may be freely moved in carving, substantially asset forth'. v

4. 'lheframe u, on centres yl0, at right angles, or nearly so, to its length, and receiving-the pattern aud gun stock, or other article, substantially as specified, whereby the pattern and article t0 be acted upon can be reversed, to present either side to the tool and tracer, as set forth. n f

.GLA holder fitted on centres, and carrying lthe pattern and gun stock or other article, and arranged substantially as specified to swing on said centres, while the tool is 'inletting or cutting the curved parts, in order that said tool may act at right angles to the surface, for tho purposes and as specified.

'6. Rotating the pattern and the article to be carved-in parallel planes at right angles to the axis on whichg they are supported, subst'autilally'as and 'for the purposes set forth.
