To all whom it may concern:

Be it known that I, HORACE C. TIMMER- MAN, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Bushing-Removing Tools; and I do hereby declare the following to be a full, clear, and exact description of the inventi'on, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a tool particularly useful for removing bushings from machinery, and especially the lower bushing around spindles and shafts of cream separators. It is an object andpurpose of the present invention to provide a tool of this character which consists 'of few parts, which can be manufactured at a low cost, and one which is of particular utility for the quick and ready removal of said bushings.

For an understanding of the invention, its structure and operation, reference may be had to the accompanying drawing in which,

Figure 1 is a perspective view of the tool, illustrating its use in removing a bushing from a cream separator.

Fig. 2 is a partial side elevation and section thereof, and,

Fig. 3 is an under plan view of the tool.

Like reference characters refer to like parts in the different views of the drawing.

I11 construction a handle 1 is provided which at one end is forked to provide two spaced apart arms 2, the same at their ends being turned upwardly as shown. Between the upwardly turned ends of the arms a block 3 is pivotally mounted on a pin 4, from which block a cylindrical rod 5 eX- tends upwardly. A. distance below and back of the block 3, a second block 6 is pivotally mounted on a pin 7 between the arms 2, and from the block 6 a screw-threaded mem ber8eXtends downwardly threading into a cap 9, it being evident that the cap may be easily adjusted to various positions on the member 8. The lower end of the cap, preferably, is notched, the notches extending across the same at right angles to each other, as indicated at 10, though any other suitable form of notches or depressions may be made in the cap to fit various ridges or projections on the surface against which the cap bears when in use.

In Fig. l the tool is shown in use to rebushings.

move the lower bushing around thelower end of the vertlcalspindle in a cream separator. The cap 9 rests upon a ledge 11,

while therod 5 passes upwardly through the hearing at 12in the upper portion of which the bushing 13 is placed. Normally,

this bushing is held very tightly by a drive fit. To remove the same, all that is necessary is for the operator to press downwardly on the end of a handle 1, whereupon great force may be transmitted against the lower end of the bushing 13 sufficient to force it upwardly, as will be evident. The adjustment of the cap 9 with respectto the screwthreaded member 8 permits the easy insertion of the rod 5 into the bearing and a positioning of the parts so that an effective leverage can be obtained.

I have shown one use of the tool and one for which it is especially designed. It is evident that the tool may be used in many other relations for the removal of bushings in many other types of machines, it being necessary merely to provide a rigid bearing against which the cap 9 may rest sufliciently close to the bushing that the end of the rod 5 may bear against the same. For. larger bushings, caps of various sizes may be placed over the end of the rod 5 as indicated at 1 1 in Fig. 2, and different sized,

caps may be used for different sizes of and is of relatively simple construction, but with it, it is possible to remove bushings irrespective of how tightly they may be held in machines. 7

I claim:

1. A tool of the character described, comprising a handle forked at one end, the ends of the arms of the fork being turned upwardly, a block pivotally mounted between the ends of said arms, a rod extending from the block, a second block pivotally mounted between the arms below and back of the first block, a screw-threaded member de pending from the block, and a. cap threaded on to said member, substantially as and for the purposes described.

2. A tool of the character described, comprising a handle forked at one end, a mem back of the first member and provided with a part adapted to extend in a downward di- Thetool consists of few parts rection, and a cap adjustably mounted on said downwardly extending part of the second member, substantially as and for. the purposes described.

3. A tool of the character described, comprising a handle, a member pivotally conneeted at one end of the handle and having a cylindrical portion extending therefrom and adapted to be positioned vertically above said end of the handle, a second mem- 10 mounted on and extending below the second 15 member, substantially as described.

In testimony whereof I afiix my signature.
