GEAR FULLER.
Application iled May 20, 1921. Serial No. 471,029.
T o all 107mm t may concern.'
Be it known that I, ROBERT W. WRIGHT, a citizen of the United States, residing at William Penn, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in Gear Pullers, of which the following is a specification.
This invention comp-rehends the provision of a tool designed to facilitate the separation of a gear from a shaft or axle, or the replacing of the gear o-n said shaft or axle, the tool being made up of a plurality of parts which can be quickly assembled for use, or disassembled so that the tool can be conveniently arranged in a tool chest or the like.
The nature and advantages of the invention will be better understood when the following detailed description is taken in connection with the accompanying drawing, the invention residing in the combination, construction and arrangement of parts as claimed.
In the drawing forming part of this application, like numerals of reference indicate similar parts in the several viewsand wherein:
Figure 1 is a plan view of the tool showing the manner of associating the same with an axle or shaft to remove a gear therefrom.
Figure 2 is a sectional view taken on line 2-2 of Figure 1.
Figure 3 is a detail view of one of the end members of the tool.
Figure 4 is a detail view of one of the intermediate portions of the tool.
The tool forming the subject matter of my invention is preferably made upof a number of detachably connected parts, to permit the tool to be carried in a small tool chest or the like, although the tool may be made in o-ne piece if desired. As illustrated, the tool comprises two intermediate sections 1() which are arranged in spaced parallel relation, and connected to the end members 11 and 12 respectively. Each of these members is substantially U-shaped, and the limbs of each member are bifurcated as at 13 to receive the adjacent ends of the intermediate sections 10,the latter being held associated with the end members by means of pins 14 which are passed transversely through the limbs of the end members and the intermediate sections as shown. These pins hold the parts ixed relatively, although the pins can be easily removed to disassemble the parts when desired. Each end member is provided with a central threaded opening in which a threaded adjusting element 15 is arranged, these elements being movable toward and away from each other for the purpose to be presently described. The endmember 15 varies from the end member 12 in that it is provided with an opening or cut-way portion 16 of a size and shape to accommodate the gear 17 and the hub 18 thereof. V
In practice, the tool is clamped in a vise or the like, and the axle or shaft 19 together with the gear 17 is arranged between the sections 10 as illustrated in Figure 1. When positioned in this manner, the gear 17 together with the hub is received by the opening or cut-way portion 16 of the end member 11. In order to remove the gear from the axle, the adjusting element 15 carried by the end. member 12 is tightened contacting the adjacent end of the shaft or axle 19, while the adjusting element 15 of the end member 11 is loosened, thus pulling the gear 17 so that the lock washers which holds the gear on the shaft or axle can be removed. When the washers have been separated from the shaft or axle 19, the adjusting element 15 o-f the end member 12 is loosened or released, while the element 15 carried by the end member 12 is tightened, thereby forcing the gear 17 from the shaft or axle 19. To replace the gear upon the axle, the gear is first arranged upon one end of the latter and both elements 15 carried by the respective end members are tightened. Then by releasing or loosening the fastening element carried by the section 11 and tightening the element 15 carried by the end member 12 it forces the gear on the shaft or axle to a position where the lock washers above referred to can be associated with the axle or shaft, thereby holding the gear in its working position.
While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall Within the scope of what is'claimed.
TWhat I claim is:
l. A. tool of the character described com- Y prising a pair of spaced parallel sections, end members of substantially U-sha-ped formation secured to the said sections, a threaded adjusting element operatingthrough the center of each end member,v and one of said end members having a. gea-r receiving 0pening for the purpose speeied.
2. A tool of the character ldescribed comprising spaced vparallel sections, end members of substantially U-shaped formation the limbs ofsaid members be-ingbifurcated to receive the adjacent ends ofsaid sections, fastening elements securing the said sections and end members together, threaded adjusting, elements operating through the center of each end memfber, and one of said end members having a gea-r receiving opening, for the purpose specified.
In testimony whereof I ax my signature.
ROBERT W. WRIGHT.
