KIRKE R. WILSOfi, OF BUFFALO, NEW YORK.

ARBOR-PRESS.

Application filed January 9, 1920. Serial No. 350,425.

To all whom it may concern:

e it known that I, KIRKE R. VVILSON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Arbor-Presses; and I do hereby declare the following to be a full, clear, and exact description of the same, 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, and to figures of reference marked thereon, which form part of this specification.

Like figures of reference refer to like parts.

This invention relates to arbor presses, particularly to that class thereof adapted for forcibly putting a gear on a shaft, as well as removing the same.

One of the objects of this invention is to provide an arbor press especially constructed for use of the two operations of putting a gear on a shaft and removing the same, without necessitating any change in the frame or parts of the press. c

Another object is to provide a serviceable and durable arbor press of such a construction as to adapt the same for use on either a geared propeller or a geared axle shaft, of a motor vehicle, thereby providing a press for accomplishing the double purpose of putting a gear onto a shaft and taking the same off, without the use of extra attachments ordinarily required for changing over the construction of an arbor press for one or the other use.

lVith these and other objects, my 1nven tion resides in a combination and arrange-- ment of parts and details of construction hereinafter described and claimed, it being understood that changes in the one embodiment of the same herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

This one embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view of an arbor press embodying my invention.

Fig. 2 is a plan view of the arbor press shown in Fig. 1, but with the parts thereof arranged to push the long shaft out of the gear.

Fig. 3 is an elevation of one of the termitube 7.

nals of the arbor two figures.

Fig. 4, is a side elevation of the arbor ter minals shown in Fig. 3, having part thereof broken away to show the incorporation of a socket piece therewith.

Fig. 5 is a sectional view of a gear parpress shown in the other tially upon thc'shaft, together with a socket in ball bearing connection with the end of the press screw.

Fig. 6 is a section taken on the line XX of Fig. 1.

.Inthe figures, the terminal ends 1 and 2 are made from like castings, each having an upright portion 3, from the bottom of which extend lugs 4', adapted to receive screws or bolts for attaching the press firmly to a sup-. port. Positioned intermediate of the terminal ends 1 and 2, is the: yoke 5, shown near the end 2. The yoke 5 is spaced from. the

terminal end 2 by pipe or tubing 6, and is spaced from the terminal end 1 by pipe or These four pieces are shown in Fig. 1 to be broken away to expose the long bolt rods 8, having bolt heads 9 and 10, and serve to hold the terminal ends 1 and 2, and the yoke 5 in fixed spaced relation.

In threaded engagement with the terminal 2 is the press screw 11, having the usual head 12 and a bar 13 in sliding engagement therewith. The bar 13 is fixed in position on the which is positioned the adapting socket 19.

Where the socket 19 is positioned concentrically in contact with the gear 18, is a central pocket v20 to receive the end of the shaft A as it protrudes beyond the gear 18 in itsfinal position. A central pocket 21 is provided in the opposite end of the adapting socket 19 to receive in journaled engagement the ball bearing end 22, of the screw 11, having a ball 23. The terminal end 1 is provided with a central boss 24, having a hole 25 therethrough. As shown in Figs. 1 and 4, the terminal end 1 is provided with a plug 26, having a pocket 27.

In Fig. 2, the plug 26 is omitted, leaving a passageway for the end of the shaft A, required in removing theshaft from the gear 17. The position of the parts shown in Fig.

of spacing pipe head 12 by the setscrew 14, which has a rod upon to repair.

relative position as shown,

attachments for a single 2 represent that taken when the gear is removed from the shaft, at which time the ball 23 bears directly upon the end of the shaft A, and hub 17 is forced in shouldered contact with the yoke 5.

The operation of the press for putting the gear on the shaft is as follows: The gear 18 is started upon the shaft A, after which, the opposite end of the shaft A is positioned in the pocket 27 of the plug 26, and the shaft is laid in the recess 16 of the yoke 5; the screw 11 having been turned out sufficiently to position the adapting socket 19 concentrically against the gear 18, after which, the ball bearing end 22 of the screw 11 is entered into the pocket 21 until the ball 23 comes in contact with the seat of the pocket, as shown in Fig. 5. The screw is then advanced, forcing the gear 18 into place on the shaft A, or until it shoulders against the yoke 5, if the yoke is positioned for limiting the movement of the gear upon the shaft. The position of the yoke 5 is shown in the figures to be fixed in a position relative to the terminal end 1, for use with a given type of axle or propeller shaft, the case in point being that of the Ford type. The purpose of making the parts of the press, fixed in is to provide means without any type and size of shaft and gear, which the ordinary garage re air man is mostly called f course, without much changeboth the terminal end 1, and the yoke 5, can be adjustably fixed in position upon the rods 8, to alter the construction slightly for a variety of lengths of shafts and positions of gears thereon. But the main objects in providing a device of this naturehaving its framework parts in fixed relation, is to cheapen its construction and to provide a device which is thoroughly adapted for use on a single type of shaft and gear.

Referring nowto Fig. tion of removing the shaft A from the gear 18, the shaft is positioned to lie in the recess 16 of the yoke5, having the hub 17 of the gear 18, in shouldered engagement with the yoke 5, and having the shaft A, in alinement with the hole 25, of the terminal end 1', and having the ball 23, of the screw in contact with the end of the shaft A. The

2 and the operascrew is then advanced, forcing the shaft A, through the gear 18, to remove the same. Having described my invention, I claim- 1. An arbor press adapted to assemble and disassemble a gear with a shaft, comprising a frame, including terminal members and spacing members, each of said terminal members having a central core and holes near the outer ends of said terminal members, a clamping screw in threaded engagement with one of said bores, parallel members holding said terminals in fixed spaced relation, a yoke crossing said parallel members and fixed in position with relation to said terminal members, said screw having a ball bearing end for frictionless contact with said shaft when removing the same from said gear.

2. An arbor press adapted for assembling and disassembling a gear with a shaft, comprising a frame, including two parallel longitudinal members, two end membersin which said longitudinal members terminate, a central boss with a hole through it on each of said end members, foot legs on each of said end members for mounting said press upon a support, a cross member. fixed midway of said end members upon said longitudinal members, said cross member having a central recess open on one side and axially positioned with reference to said bosses on said end. members, and a jack screw in threaded. engagement with one of said end members, positioned to be coaxial with both of said end members.

3. Tn an arbor press adapted for assembling and disassembling a gear with a shaft, -iongitudinal frame, a jack screw in threaded engagement with one end'of said frame for forcing a longitudinal movement within said frame upon a piece held therein, a pocketed plug releasably engaging one end of said frame opposite to said screw, an adapting socket for engaging concentrically a gear placed with a shaft in said frame.

for assemblage therewith, said socket being adapted to engage the inner end of said screw, and means for turning said screw to force said gear in place on said shaft and to force said shaft against end contact with said plug.
