JOHN G. PUSEY, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 3 7,705, dated February 17, 1863.

To all whom it may. concern.-

Be it known that 1, JOHN G. PUsEY, of the Figure 1 is a side elevation of my said machine. Fig. 2 is an end view. Fig. 3 is a plan with part of the head of cutters removed,

and Fig. 4 is an inverted plan of the holder for the pattern and gun-stock.

Similar marks of reference designate the 5 me parts.

The-nature of my said invention consists in a reversible holder, carrying the pattern and the-gun-s'tock or other article to be mortised,--

bored, or carved, so that the gun-stock can be carved to receive the barrel, breech-tang, and other parts on the top of the stock, and then turned over with the pattern and slotted or inlet to receive the .ramrod, the triggerplate and guard, &c., and in consequence of the metal pattern and gun-stock being firmly held in the said reversible holder, the various slots must be exactly on line with'each' other in the gun-stock, and there is'no risk of the parts not coming exactly to place, becausc the present mode of detaching the stock after one side has been out, and thencuttingthe other side at a separate operation, is dispensed with, and the stock is held in place until out .all around in one direction either on the top and bottom sides of th'e'stock or on the right and left sides of the stock, ac-

cording to the way it is introduced in the.

holder.

My invention also relates to the mode of holding the cutters soas to present any particular one to the work to be performed, and.

guide it by theparticular pattern that isfollowed in mortising gunstoclrg'boring or carving them or other articles.

-In the drawings, a is the bed-plate of the machine; b b are vertical frames carrying an upright shaft, 0, with a pulley, d, driven by competent power. 6 e e e are arms jointed at one end (at l 1) to the vertical shafts f f, that are. sustained at their ends by the center screws, 2 2, entering the ends of said shafts, or any other suitable hearing may be used. These arms 6 c are parallel to each other, and their outer ends are connected by universal joints to the plate carrying the head 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 4, while said shafts 3 3 are attached to the plate g by center screws, 5 5. It will now be understood that the plate 9 can be moved across the bed a, or be raised upor lowered, and that the arms 6 e c e preserve the same parallel to its normal position. The weight of these arms and plate and parts 'carried by them is sustained by springs k h; or counterbalanceweights might be provided, if desired. This plate 9 carries a circular head, 7c,- of cuttingor carving tools. This circular plate It has a flanged edge kept to the plate 9 by the overhanging edges of the plates Jo, which, however, allow this plate I: to berevolved either by hand or by power, and stopped at any desired point. I have represented a pin, 6, to be pressed into a-hole 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. On this circular head it are mounted any desired number of radiating stocks, 5 l,'carrying cutters or tools 0 o. I have shown eight such stocks and tools, but the number might be greater or less. The interior of the head it is open, and in this the pulleys a not the respective stocks stand. at is a pulley set on an arbor or gudgeon attached to the bar 10, that is afiixed to the back of the plate g, and p is a slide and fork by which the belt d. from the pulley d can be slippedo fi 0t 4% upon one oi the pulleys n, or the reverse. -When the said belt is running on the pulley m, the circular head It, cutter-stocks, and pulleys can be revolved, and when the particular tool required is brought vertically below m, the pin 6 is slipped in to hold-the circular plate k, and then the belt (1 slipped down upon the pulley below it 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, of the size and shape moves the entire head of cutters up or down or crosswise of the bed a, and by giving to the article to be operated on, together with the pattern, an end motion along the bed a the whole surface of the article to be slotted,

'mortised, or carved can be brought to the action of the cutters, and one cutter can be carried out of action and anotherbrought into position very speedily. Thereby any usual cutter that may 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 eachcutter-stock is avoided. In' place of the pulleys n n, a clutch might be provided-near the end of l, and the pulley n might have a slight play, so as to connect with said clutch on I and rotate the stock and tool attached. It will be evident that the freedom with which the whole cutter-head moves on and with the parallel arms a e c e greatly facilitates the carving or cutting operations, because the attendant can cause the tracer to follow the pattern much more easily. The same movements could be. obtained if the cutter-head were mounted on a double slide on astationaryframe; but I prefer the parallel bars.

In order to present the article-to be carved, bored. or mortised to the tool, ,I make use of a frame, r, fitted to slide on the bed-plate a, and tbe'same is to be moved by the pinion 7, takin g the rack 8, said pinion being turned by the crank 9,0r any other suitable device. Within this frame 1' the pattern is held, and also the piece of wood to be operated upon.

I. have shown in the drawings a gun-stock, s, and a pattern, it. These are to be of any desired size or character, and the pattern t is to be of 1netal,with all the mortises, grooves, &c.,

required for receiving the parts-of the gun, as

usual. This metal pattern is held in the holderframe a, that is attached by the center pins, 10 10, to the frame r. This holder-frameu is constructed to fit the opening in the frame 1', so as 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, and clamped firmlyin place by a screw at ll, or any other convenient mechanism whereby said stock is rigidly secured in place. The distance between the centers of the stock and pattern is to be the same as that between thecutteror tool 0' and the tracer q. It will now be seen that the upper side of the stock can be carved or inlet corresponding to the pattern by bringing the proper tools into action, and then the stock and pattern can be reversed with the holder u, and the parts-cut out on the-under side of the stock; and by this means the stock and pattern must corre- .s 0nd exact] because their relative position is not disturbed until all the mortises, holes,

&0., are formed bothabove and bclow the stock. In cutting along the curved part of thestock toreceive the breech-tang, or in cutting to receive the guard and trigger plate on the curved under side of the stock, the said surface is to be kept at'right angles to. the axis of the cutting-tool (in order that said tool may leave the inlet surface smooth and even) by .thrning the holder-frame on its centers 10 10 as the cutting progresses. 'done by a slot, 12, in the side of the holder 11, receiving a stationary pin, 13,- whieh turns the said holder u, stock 8, and pattern t as the frame 1 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 mortising the side of the stock to receive the lock-plate and other parts, both the stock and pattern have to be entered at right angles to their present position.

I do not claim a series of stocks and tools mounted on circular heads capable of rotation to bring any one of the tools to the posi tion required in operatin g it, as the same is found in several machines and in the patent of H. W. Oliver, July 1, 1862. In these instances, however, the tool-stockshave been parallel to each other, and capable of each receiving a motion independent ofthe other. Neither do I claim revolving. the gun-stock upon centers or bearings at or near the ends of such stock. In my improvement thepattern corresponds on both sides with themortises, &c'., of the stock, and is reversed with the stock on centers or trunnions at right angles to the stock and pattern.

What I claim, and desire to secure by Letters Patent, is-'-- 1. Arranging a series of tool-stocks to ra diate from a common center, in combination with a series of tracers, substantially as specified, whereby all "the tools and tracers may be moved together in mortising, boring, or carving, but the tools not in use will by their divergence be out of the way, as set forth.

2. The arrangement of the pulley m in the middle of'the circulanh'ead k, and ofthe fork p, or its equivalent, for receiving and changing the belt (1', in the manner set forth. 3. The parallel bars e e e e, fitted and arranged substantially as specified, in combination'with the circular head It, for the purposes and as specified.

4. The frame at on centers 10 at right angles, or nearly so, to its length, and receiving the pattern and gun-stock or other article, substantially as specified, whereby the pattern and article to be acted upon can be reversed This may be to firesent either side to the tool and tracer, act'at right angles to the stirfaxze the pattern and gun-stock, and arranged, subs'mos a for the puras set forth. poses and as specified.
