WOOD-CARVING MACHINE.

` SPECIFICATION forming part of Letters Patent No. 25795'7, dated 'May 16, 1882.

Application filed March l1, 1882.

To all whom it may concern:

Be it known that I, GERHARD Marais, of

the city, county, and State of New York, have `supported slotted and axially-turning standards. The original and the blanks to be carved are fastened to these standards, and can be moved up and downward in slots of the same.

Centrally between these two standards is arranged a iixed socket supporting an axiallymovable forked standard having bearings for the pivot-shaft of one or more levers which carry at their ends journals for the transverse carving-tools. One of the levers carries at one end a guide-pin moving along the model. The carving-tools are revolved by belt-andpulley transmissions.

In the drawings, Figure l represents a side elevation of my improved carving-tool. Fig. 2 is a plan, and Fig. 3 an end elevation, of the same. y

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a guide bed or table of oblong shape having longitudinal ways, upon which are two carriages, B and C, which are moved in opposite direction to and from each otherby a longitudinal spindle, D, having right-and-left-hand screw-threads a and a. The spin'dlc passes through fixed nuts on lm.' at the under side of said carriages. Upon the carriages B and C are supported upright standards E E by turn-tables c e at their lower ends, and by central pivots set into sockets of the carriage. The standards E E are firmly clamped to the carriages by screw-nuts applied to the pivots at the under side ot' the carriages. The standards have vertical slots to which the plates that carry the model and the blanks to be worked upon are fastened by (No model.)

clamp-screws or other devices, b I).V The model and blanks can also be turned axially on theirv clamping-bolts, so as to be set into any desired position to the guide-pin and carvingtools. llhe carving-tools are journaled in bearings at the outer ends of levers H and I, Fig. l, which are fulcrumed to a forked upright standard, L, that is set into axed socket, G, of table A. lhe forked standard L is axially movable in the supporting-socket Gr, whereby the levers may be oscillated in horizontal planes. The levers H and I are connected to each other by coupling-rods l Z, near both ends of the same. As both levers H and I are coupled together, they are compelled to perform exactly the same motion thouglb out. One end of one of the levers is provided with a guiding-pin, d, which corresponds exactly tothe size ofthe carving-tools d',mounted in the remaining ends of the levers. The guiding-pin d is placed opposite the original which is t0 be copied, while the carving-tools dare designed to cut out the contours of the original upon the blanks arranged on the vertical standards E E. The carving-tools are revolved by belt-and-pulley transmissions, which are indicated clearly in Figs. l and 3, so that when the guide-pin is passed over the face of lheorginal the carving-tools .will reproduce the contours of the same on the blanks. As the standards supporting the original and blanks are moved in opposite direction to each` other by the spindle D the model and blanks are passed along the guide-pin and the carvingtools, whereby when two levers are employed three copies are made. While one lever is employed only one copy is made. It' more than two levers are used, a correspond ingly larger number of copies can be made at the same time. rEhe machine may also be made with two or more levers extending only to one side of the central forked standard,in which case only one movable standard is necessary, to which the model and blanks are applied.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of a bed-plate, A, carriages B C, arranged to reciprocate in opposite directions to each other, upright standards E E', applied to the carriages for supporting model and blanks, one or more levers, Hand I, which ICQ are fnlcrnmed 4to a' forked axially turning my invention I have signed niyname in presstandard, G, and provided at the ends with a ence of two subscribing witnesses. guide-pin and carving-tools, and means for Q transmitting rotary motion to the carving- GERHARD MATHL 5 tools, substantially as and for the purpose set Witnesses:
