shaper and on various other machines of analogous nature.

My invention is more especially designed for fitting brasses or boxes, as also shoes and wedges for connecting rods of locomotives,

although I do not limit myself thereto, as

my invention contemplates, as coming with-, in its scope, any use to which an improved tool holder may be applied. I have shown my invention as applied to the head of a cutter bar.

My invention consists of the construction,

combination, and arrangement of devices and appliances hereinafter described and claimed and illustrated in the accompanying drawings, in which- Figure 1. is a view in side elevation. Fig. 2. is a view in front elevation. Fig. 3. is an enlarged front view of the tool head with the clamping plate removed. Fig. 4. is a view in section on the line' 4:4 Fig. 3 with the crossing tools in place. Fig. 5. .is a

similar view with the longitudinal tool in place. Fig. 6. is a front elevationsimilar to Fig. 3. with the setting tool or gage in place. Fig. 7. is a view in section onvthe line 7-7 Fig. 6. Fig. 8. is a rear elevation of the mechanism shown in Fig. 6. Fig. 9. is a View in section on the line 99 Fig. 8.

I carry out my invention as follows: As shown in the drawings my improved tool holder is constructed with a head 1 provided with an arm 2 to be engaged in any suitable cutter head 3. A cutter bar carrying the head 3 is indicated at 1-. 1

Upon the head of the tool holder is engaged a clamping plate 5. The head of the tool holder is constructed with recesses or grooves at 6 and 7 to receive

corresponding tools

8 and 9, said recesses and tools being arranged on diagonal lines and crossing each other as shown. The

tools

8 and 9 when in place cross each other centrally of the tool holder head, whereby said tools may project from the head at two opposite points, or at the opposite edges of the tool holder head. This construction enables the

tools

8 and 9 to operate upon the opposite flanges of a piece of work indicated at 10. The

tools

8 and 9 are held in the head of the tool holder by means of

screws

11 and 12 clamping upon said tools. The clamping plate itself is held upon the head of the tool .holder by means of screws 13. It will be.

evident that the

tools

8 and 9 can readily be removed or adjustedby loosening the

corresponding screws

11 and 12.

To adapt the tool holder to receive a tool for other work, as for planing between the.

opposite flanges ofa piece of work, the head of the tool holder is further constructed with a recess or groove 14 to receive a corresponding tool 15 extending longitudinally of the holder, the

tools

8 and 9 being removed when it is desired to employ the tool 15, the tool 15 being removed when it is desired to use the

tools

8 and 9. The tool 15 is held in place beneath the clamping plate by means of a. set screw 16.

In order to readily set the

tools

8 and 9 accurately and uniformly, I provide a setting device or gage consisting essentially of a longitudinal arm 17, fitting into a recess 18 in the tool holder upon the opposite s1de of the tool holder head from the clamping plate 5, said arm being slotted as shown at 19 to pass astride a pin 20 engaged with said head, said pin being provided with a hand nut 21 threaded upon said pin to clamp the arm 17 in place upon the head; the longitudinal arm 17 has a transversearm 22 adjustably engaged therewith. The ar1n17 is preferably constructed with a transverse groove. 23 to receive said transverse arm, said latter ar1n being constructed with an elongated slot 2 1 through which the transverse armis held in engagement with the longi tudinal arm by means of a set screw 25 provided with. a thumb nut 26 threaded thereupon. The extremities of the transverse arm are constructed with

elongated slots

27 and 28 through which adjustable stops or

angle plates

29 and 30 are engaged upon the transverse arm as by screws 31 and 32. The head of the tool holder is also provided with an adjustable stop 33. The longitudinal arm of the setting device or gage is provided with a shoulder or pin 34 to abut against said stop. By this means it will be seen the setting implement may be readily applied in just the right position longitudinally of the tool holder to set the

tools

8 and 9, after the stop 33 has been once properly adjusted. Said stop is shown constructed with an elongated slot 85, the same being held in place by means of a screw 36. I have shown the screw 20 provided with a spring 37 to keep a tension on the nut 21 so that it will not jar loose when the tool is taking its cut, a washer 38 intervening between the spring and the thumb nut.

The operation of the device will now be understood. By employing the setting instrument as described, the

diagonal cutting tools

8 and 9 may readily be set in exactly the position desired and uniformly. By having the

angle plates

29 and 30 of the setting implement adjustable it will be evident that the adjacent ends of the diagonal cutters may be set at any desired distance apart. One of the flanges of the

adjustable angle plates

29 and 30 of the setting device are respectively shown, in Fig. 9, constructed with a projecting arm indicated at 4-0. Supposing it is desired to fit a box indicated at 10, in Figs. 1 and 2 for example, for the strap of a locomotive connecting rod. To set the tools in just the right position for making the necessary cut. the arms 40 of the angle plates are adjusted against the opposite sides of the strap illustrated at 41, Fig. 9. This gives the exact distance across the strap which is the size of the groove which is to be cut in the box to receive the strap. lVhen the

tools

8 and 9 have been set correspondingly the work can be accurately carried on, without further trouble. No calipering is required, and, indeed, owing to one of the

tools

8 and 9 lying on the other, it is impossible to caliper them with a pair of calipers, so that the setting device hereinbefore described is an absolutely essential feature of the tool holder, in order that the tools may be properly set, and the work be properly done. For the proper adjustment of the

angle plates

29 and 30 the arm 22 is shown provided with a micrometer scale indicated at 42.
