Henry J. F. Nestler, Atchison, Kans. Application September 14, 1936, Serial No. 100,725
1 Claim. (01. 2945) This invention relates to gear pullers and has for the primary object the provision of a simple and inexpensive device of this character which is easy and quick to operate by a person and is capable of developing maximum pulling force for the removal of gears and similar devices from shafts and the like.
With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view illustrating a gear puller constructed in accordance with my invention.
Figure 2 is an end view illustrating the same.
Referring in detail to the drawing, the numeral I indicates parallel plates each having one end bent angularly and sharpened to form a jaw 2.
The plates I are' provided with spaced openings 3. The openings of one plate are arranged to align with the openings of the other plate.
Bars 4 and 5 pass through certain aligned openings of the plates so that said plates may he slid endwise of said bars for the purpose of adjusting the jaws 2 towards and from each other. The bar 4 is solid, while the bar 5 is tubular. The
bar 4 has an enlargement 6 provided with a screwthreaded opening, the threads of which mesh with feed threads 1 of a feed bar 8. One end or the bar 8 is shaped or reduced, as shown at 9. for engagement with a shaft, axle or like device, and the jaws are brought in; engagement with a gear puller or similar device mounted on said shaft or axle. The bar 5 has an opening therethrough through which extends the feed bar 8 and located in said opening is a bushing 9 for the purpose of protecting the feed threads I. One end of the feed bar is shaped to form wrench or tool engaging faces "I. The bars .4 and 5 cooperate in preventing the plates I from movin out of parallelism.
In operation, the jaws are applied to a gear and the end 9 of the feed bar bears against the shaft and by rotating said feed bar the gear will be pulled from the shaft with ease.
Having described the invention, I claim:
A gear puller comprising plates, jaws integral with said plates to engage a gear, bars slidable through said plates for maintaining said plates in parallelism and to permit the plates to move towards and from each other, said bars having openings, feed threads formed on the walls of one of the openings, at bushing located in the other opening, a feed bar having feed threads meshing with the feed threads of said opening and extending through the bushing and adapted to have one end engaged with a shaft on which the gear is located whereby rotation of the feed bar will bring about a removal of the gear from the shaft.
