TOOL-HQLDER-OSCILLATING DEVICE FOR PLANlNG-MACHINES.

SPEIEIFIQATION forming part of Letters Patent No. 339,212, dated April 6, 1886.

Application filed July 22, 1385. Serial No. 172,264. (No model.)

.To ctZZ whom it may concern.-

Be it known that I, GUSTAVEDMUND REIN- HARDT, a citizen of Germany, residing at Iieipsic, in the Empire of Germany, have invented a new and useful Improvement in Tool- Holder-Oscillating Devices for Planing-Ma chines, of which the following is a full and exact specification.

This invention relates to improvements on planing-machines; and. it consists in novel mechanism whereby a swinging motion is communicated to the tool-holder. This will enable a double-edged cutter to cut or plane during the forward as well as during the backward motion of the machine.

In theaccompanying drawings, Figure]. is a front view of a support of a planing-machine. Fig. 2 is a cross-section of the same. Fig. 3 is a back view of the carriage, partly in section; and Figs. 4, 5, and 6 are details referred to in the following specification.

The cross-slide A is fitted upon the vertical slide I), attached to the upright frame of the machine not shown in the drawings.) This cross-slide A receives sidewise motion by means of the screw 0, operated by the pawls bb arranged on the levers c c. Theselevers are connected to the rod a, which receives motion in the usual manner. The arm 0 is elongated and connected by rod (Z with alever, e, placed upon a shaft, f, so as to be capable of turning freely upon the same. This shaftfis supported parallel to the feed-screw o, by bracketsff, attached to the vertical slide B. Close to the lever 6 there is firmly attached to the shaftfa disk, 9. This disk 9 is provided with studs h 71 capable of being regulated and against which the lever e is made to strike, and to thus communicate the desired motion to the shaft 1". 'Upon the shaft f the bevel-gear 2' is arranged, capable of sliding in a groove on said shaft and meshing into a corresponding bevel-gear, 2", connected toawheel, it. (See Figs. etand 5.) One end of this bevel-gear t" is supported in a frame f that slides on the shaftf and straddles the bevel-gear The other ends or hubs of the wheels 2' and k are supported in a lever, 'v, turning on a bolt, o, attached to the carriage D. This bolt 1: supports a wheel, k, that meshes into the wheel is. The wheel k is fastened upon the bolt r by means of the set- J screw n, Fig. 3, to regulate its exact position.

The carriage D is provided with a spindle, 0 having a fixed collar or hub, in, and a second k collar, 11, working on the threaded part of said spindle o". The fixed collar or hub mis connected with the gear-wheel It? by a rod, Z, and the hub or collar n is provided with a convex projection, or, engaging a corresponding socket, 1), at the back of the tool-holder p. This rod Z forms the connecting-rod between the wheel k and the hub m, which is firmly attached to the spindle 0 as above described, and converts the rotary motion of the wheel k into a reciprocating motion of the hub m or spindle 0. The hub 11 is held fast on the threaded part of the spindle 0 and thus reeei ves the reciprocating motion from its spindle o By means of the threaded part of the spin dle 0 the hub a can be raised or lowered to correspond with the position of the tool-holder p. The tool-holder 1) turns in side bearings, 1" w on the carriage z.

The operation of the above described mechanism is as follows: The cross-slide A, with carriages D t, and tool-holderp, receives sidewise motion 011 the vertical slide B by the screw 0, operated by rod a in the usual manner. The motion of this rod a is commnnicated by arm 0 and rod d to lever e, which latter (by coming in contact with one or the other of the studs h h gives an oscillating motion to the shaft f. This motion given to the shaft f is communicated by bevelgear 2' i and wheel k, to the wheel k and from the latter by the connecting-rod Zto the spindle 0", thus producing a reciprocating motion of the spindle. This motion is again communicated by projection a to the toolholder 19, turning on the bearings r 0-, thus producing an oscillating motion of said toolholder. In this way either the one or the other side or cutting-edge of the tool (1 is brought into action, according to the direction of the motion of the planing-table.

In the carriage D there is placed a second screw-spindle, 0, on the side of the spindle 0*, and connected with the same by gearing u a.

These gear-wheels au turn in the upper part 100 of the carriage D, and the spindles 0 0 pass through the same and are connected thereto by suitable feathers.

The spindle 0 has for its object to regulate the position of the carriage t, by passing through a boss, 0, attached to the carriage it, while. the spindle 0 produces the oscillation of the tool-holder 1), in the manner above described.

projection at; and with tool-holder 1), having socket p, and'with rod Z and collar m, substantially as and for the purpose described.

2. The combination of cross-slide A, operated by feed-screw C, with the spindle 0 bevelgear i wheels k 70, rod 1, and shaft 7, the shaft f and screw 0 receiving motion from rod a by means of intermediate gearing, substantially as specified.

3. The combination of tool-holder p, oscillating 011 centers 0- r with reciprocating 25 spindle 0, rod Z, collars m n, and with screw 0 and wheels uu as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two 30 subscribing witnesses.
