Tall whom t may concern.-

Be it known that we, MATTHEW MORTON and HENRY F.. MORTON, citizens of the United States, residing at Muskegon Heights, county of Muskegon, State of Michigan, have invented a certain new and useful Improvement in Key-Seat-Cutting Machines; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention has for its object certain new and useful improvements in a key-seatcutting machine, our` invention being designed to provide such a machine of superior utility; and it consists of the construction, combination, and arrangement of devices hereinafter specified and claimed, and illustrated in the accompanying drawings, in which- Figure l is a view, partly in side elevation and partly in section, illustrating features of our invention. Fig. 2 is a horizontal section on the line 2 2, Fig. l. Fig. 3 is a view in horizontal section on the line 3 3, Fig. l. Fig. 4. is a plan View. Fig. 5 is a detail View of the tilting frame. Fig. 6 is a'rear elevation of the same. Fig. 7 is a vertical section on the line 7 7, Fig. l. Fig. Sis a partial rear elevation. Fig. 9 is a partial side elevation. Fig. l0 is a detail view of the eccentric-shaft with related parts shown in dotted lines. Figli is a detail view of the crank. Fig. 12 is a detail view of the swivel for the connecting-rod.

We carry out our invention as follows:

A represents a xed frame or support provided with a bed or table A.

B is a tilting frame having a jointed yengagement toward its base with the fixed frame A. 'The iixed frame is preferably made bifurcated at its lower end, as indicated more particularly in Fig. 2, and is provided with two sleeves or bearings C C', upon the adjacent ends of which the tilting frame is journaled, as indicated at Z7, Fig. 2, said tilting frame being also preferably bifurcated toward its lower end, as indicated in Fig. 2.

D is a reciprocatory cutter-bar, preferably engaged in a holder D', provided toward its lower end with a rack-bar or toothed portion,

(indicated at D2.) The holder D reciprocates frame B, it will be understood, being jointedly supported upon the sleeves or bearings C C, may readily be adjusted, the cutter-bar D being carried therewith held in the guides CZ d of said tiltingV frame. By this means the cutter-bar may be tilted to any desired angle in a ready and convenient manner.

The manner of engaging the cutter-bar in the holder D' forms no special feature of the present invention, as the cutter-bar may be engaged in any suitable holder in any desired manner. However, the holder D', as shown in the drawings, is held in tlie guides or ways of the tilting frame by means of plates d', bolted thereto, as shown, the tilting frame being preferably provided with lateral flanges B2, forming said ways and to which said plates are fulcrumed. The cutter-bar D is shown engaged with the holder D by means of a plate D2, bolted to the holder, as by bolts cl2. Upon the upper surface or bed B of the tilting frame B is supported a post F, toward the top of which is engaged an arm G, projecting forward and against the cutter bar to form a support for the upper end of the cutter-bar to prevent the cutter-bar from springing away from the work. This arm G is made adjustable upon the post in any suitable manner, as by means of an encircling sleeve G and binding-screw G2. The forward end G3 of the arm G hasan adjustable connection therewith in any suitable manner, as

by means of an adjusting-nut g, having a threaded engagement upon the forward portion Gof the arm, the nut being held in the adjacent end of the arm G -by means of a binding-screw g. Upon the upper surface or bed B of the tilting frame is also engaged a bearing-plate b2, supporting a brace or bearing b against the rear of the cutter-bar, so that the bar is braced adjacent to the bed of the machine and thereabove in a iirm and effectual manner. The post F is made adj ustable upon the tilting frame B in any suitable manner. To this end the upper surface IOO or bed B of the tilting frame may be formed with elongated slots, (indicated in Fig. tat b2 and in cross-section in Fig. 7,) through which the base of thepost is bolted, as indicated at b3. The bearing-plate b may also be adjusted in a similar manner by means of bolts b4, engaged in a'grcove b5 in the bed B.

Il represents the usual lever for forcing the cutter to the work, said lever being provided with an operating-rod H and hand-wheel H2. The tilting table may be adj ustably connected with said lever by means of a rod J, connected with the lever and jointedly connected with a threaded bar J', as shown at j, the threaded portion J being engaged with an adjacent portion of the tilting frame and provided with a hand wheel J2. The bed B of the tilting frame is cut away, as indicated at B3, for the passage of the lever H. We prefer to provide the frame B with a scale, (shown at K,) the main frame being provided with an index-finger K to facilitate the adjustment of the tilting frame in desired position.

L indicates a gear or other work in which a key-seat is to be cut, the work being located upon the bed of the fixed frame. By adjusting the position of the cutter-bar bymeans of the tilting frame it is evident that the operator can readily get a desired taper to the key-seat.

Our invention contemplates, moreover, means for automatically retracting the cutter-bar, so that it may clear the work on its, return movement. To this end We provide, as shown in the accompanying drawings, a shaft M, having au eccentric or cam m at its upper end, said eccentric or cam being suitably engaged with the lever H, as at m. The shaft M is engaged upon themaehine in any suitable manner, as by means of abracket N, bolted to the frame of the machine, the lever H being constructed with an orifice, as at h, to

receive the eccentric m. The dotted line 10 10 in Fig. l0 denotes the longitudinal center line of the shaft, and it will be evident that when the said shaft is rotated upon its axis the eccentric will actuate the lever H accordingly. The shaft M may be engaged with the lever H in any suitable manner, as

by means of a Washer m2 and nut m3 upon Upon the.

the upper extremity of said shaft. lower end of the shaft is'engaged a crank P, the crank being held in place in any suitable manner,as by a nut mland intervening Washer m5. Vith the outer end of said crank is engaged a connecting-rod Q', as by means of j an intervenlng swivel Q, said connecting-rod,

being united to the ordinary shifting mechanism of the machine, as toashifting-bar Q2, connected with the belt-shifter Q4, as bya rod Q3, the bar Q2 being actuated in any suitable manner by the movement of the cutter-bar. The parts, it will be understood, are scadjusted and worked that when the shifting mechanism is reversed the shaft M will be partially rotated accordingly, thereby actuating the lever H in a corresponding manner,

permitting the cutter-bar in its return movement tc clear the work.

We prefer to make the bearing b acontinuous and removable bearing, said bearing being of suihcient length to be continuous through the entire length of cut for use in long deep hubs.

That we claim as our invention is- 1. The combination of a fixed frame, a tilting frame, formed with bearings engaged in the fixed frame, a shaft journaled in said bearings provided with a pinion intermediate said bearings, and a reciprocatory cutter provided with a rack meshing with said pinion, for the purpose set forth.
