JACK FOR"REMOVING PINIONS, ETC., FROM SHAFTS.

Application filed February 3, 1921.

To aZZ whom it may concern:

Be it known that we, EDWARD V. CARTER and ALBERT W. SPRAGUE, citizens of the United States of America, and residents of Huntington, county of Cabell, and State of West Virginia, have invented certain new and useful Improvements in Jacks for Removing Pinions, Etc, from Shafts, of which the following is a full and clear specification.

The object of this invention is to provide a simple Inanually-operable device for stripping or removing pinions or bearings, collars, etc., from shafts, and it consists of certain novel features described and claimed.

In the drawing- Fig. l is a perspective form of our apparatus;

Fig. 2 is a similar view of a part of the view of a simple apparatus showing a different manner of apl in it p Tigi 3 is a vertical longitudinal sectional view showing one way of applying the apparatus;

F ig.. 4 is a transverse section 011 the line 4-4 of Fig. 3.

In the drawing, 5 designates a cylinder closed at one end and openat the other end. Tapped through the thickened closed end of this 0- linder is a screw 6 which at its outer en is provided with a handle 7 for turning it and at its other end (which inner end lies within the cylinder 5) is provided with a pointed centering-pin 8. Near the open end of the cylinder, it is provided with a pair of transverse slots 9 formed at diametrically-opposite points. In connection with the tool thus described, we employ an abutment fork 10 having a large fork 11 at one end and a smaller fork 12 at the other end.

In applying this tool, the open end of the cylinder is slipped over the end of the shaft carrying the pinion 13, the center 8 being centered in the end of the shaft 14. carrying the pinion this shaft in the present instance being the shaft of an armature 15. Then the fork 11 is passed through the slot like notches 9 in the opposite sides of the cylinder, the cylinder being positioned so that the arms of the fork will engage behind the pinion, as shown in Fig. 3. Then, by screw- Specification of Letters Patent.

Patented Jan. 17, 1922.

Serial No. 442,097.

ing inwardly the screw 6, it will be seen that I is brought into requisition. This smaller fork is passed through the slots 9 in the manner shown in Fig. 2, the ball-bearing be ing of less diameter than the pinion and being of too small a diameter to be engaged by the arms of the fork 11.

It will be observed that this device may be employed for removing collars, etc. from shafts as well as pinions and ball-bearings, and it will be observed also that additional different-sized forks may be supplied with the tool so as to render the device operative with smaller or larger pinions, etc. It will be observed also that it is not essential that the several forks supplied with the tool shall be made integral, as a set of separate individual forks may be used, and it will be further observed that the cylinder 5 forms virtually a pulling yoke and that, therefore, it is not essential that it shall be a full or true cylinder, the cylindrical form being chosen because of convenience and simplicity of manufacture.

The nature and scope of the invention havin been thus indicated and its preferred emboc iment having been specifically describe what is claimed as new is:

1. In a tool of the class set forth, a yoke like member having a cylindrical open end provided with a slot in one side, a screw entering the other end of the yoke-like memher and adapted to push against the end of the shaft, and an abutment member insertable in said slot to engage behind the device that is to be pulled off the shaft.

2. In a tool of the class set forth, a yokelike member having a cylindrical open end provided with slots at opposite sides, a screw entering the other end of the yoke-like member and adapted to push against the end of the shaft, and a fork abutment member insertable in said slot to engage behind the device that is to be pulled off the shaft.

3. In a tool of the class set forth, a yoke like member having a cylindrical open end provided with slots at opposite sides, a screw entering the other end of the yoke-like member and adapted to push against the end of the shaft, and a fork abutment memberini serteble in said slot to engage behind the device that is to be pulled off the shaft, said abutment member beinguprovided with two EDWARD v. CARTER. ALBERT W. SPRAGUE.
