Application 111611 January 12, 1925. Serial No. 2.007.

My present invention has reference to a tool for pulling terminals from the poles of store e batteries and incidentally for pull-- ing bus ings, timing gears and all other kinds of machinery from their bearings,-and has for its object the provision of novel means for adjusting the tooth carryin arms of the device with respect toeach ot er to effectively grip therebetween the battery terminal or other article to' be pulled, and wherein the pulling action is effected by the contacting engagement of a longitudinally wherein there is screwed through the block an element designed to contact with a rigid support, such for instance as the pole of a battery on which the terminal to be pulled is arranged, and wherein the rotation of the threaded element will draw on the arms to effect the pulling operation.

The invention further consists in other novel features of construction, combination and operative association of parts such as is disclosed by the drawings which accompany and which form part of this applica=- tion.

In the drawings Figure 1 is a side elevation of the ment. 1

Figure 2 is an edge view thereof. Figure 3 is a sectional view on the line 33 of Figure 1.

, Figure 4 is a side elevation with parts in section, illustrating the jaws on the arms engaging a bushing to be pulled.

Figure 5 is a side elevation showing the manner in which a sleeve is to be pulled.

Figure 6 is a fragmentary perspective view of the aw end of one ofthe arms illustrated in Figure 5.

Figure 7 is a fragmentar elevation illustratin the manner in whic the tool is em ploye for pulling a terminal from a battery pole.

improve- Figure 8 is a similar view showing the] manner in which the tool grips a corroded and frosted battery terminal.

As disclosed by the drawings I employ a pair of opposed arms 1 and 2 respectively.

Preferably these arms are made up of two strips of metal, and each of the arms has its inner edge, adjacent to one of its ends, formed with one or more saw teeth which provide what maybe termed jaws 3. The

plates constituting the arms have their ends, I

opposite that provided with the jaws, bent outwardly and angularly to provide forks 4. The forked ends of the respective arms are arranged in lapping relation and are secured together by pivot means 5. also enter central openings in a cross sectionally rounded block 6 which provides the head of the tool.

The blockl5 has a central threaded portion therethrough, arranged transversely with respect to its pivotal connection with the arms, and threaded through this opening there is a screw 7 having its outer end formed with a These pivots j head 8, the said head being provided with oppositely extending arms 9 whereby the screw may be threaded through the block in either direction.

a The screw has on its opposite end ahead 10, and this head is designed to rest on a support, such as a conical element 11 on which a bushing 12 is wedged.

The arm 1 has its outer edge formed with a notch 13, and this notch is covered by a plate 14 secured on the said arm.

Pivotally secured, as at 15, to th arm 2 there are the arms of a yoke 16. The yoke straddles the arms 1, 2, and the outer or connecting element of the yoke has a threaded opening therethrough. Screwed through this opening there is a threaded shank 17. The shankhas an outer headed portion 18 and its inner portion is reduced, as at 19,'to

pass throughan opening in the plate 14. The reduced portion 19 terminates in a head 20 which is received in the notch 13 of the arm 1.

It will be apparent that by screwing the headed element 17 in one direction, the arms 1 and 2 will be brought toward each other so that one of the toothed jaws 3 thereon will rip the lower edge of the bushing 12 and firmly sustain the tool on the bushing. The tool is further sustained by the contacting engagement of the swiveled head 10 with the element 11. By turning the screw in one direction, the armsrl and2 f willbe drawn toward the headed end of the said screw and thereby easily extracting the bushing 12. 1

The construction illustrated in Figures 5 and 6 is similar to that previously described," except that the arms 1 and 2' havetheir outer ends formed with lateral extensionsproviding jaws 3-. These jaws may be either inwardly or outwardl When outwardly directed the aws .en ge the lower edge of a sleeve or the like w ich is, wed ed in an opening therefor, The

5 end of the head of the screw in port 21. The sleeve is withdrawn by the turning of the swivele this instance, rests on a sup screw. I

,So far I have described my improvement as a ulling device for bush ngs, sleeves or thelli e, but it is to be understood that the improvement is essentially designed for pulling the lead terminals from the posts of storage batteries.

These terminals are susceptible .to disintegration by the battery acid, so that the outer surfaces therof are frequently rendered uneven, and the said terminals become what is termed frosted on the oles or posts. There is no' manner in which terminals, but with m cons'tructionand as clearly illustrated'in igures 7 and 8 the toothed 'aws on thearms of the improvement wi bite into the sides of the terminals 20, regardless of the outerconfi' ration thereof, that is, regardless of the ape a tool can be inserted beneath the ofthe terminal "which has beenfpartly eaten by the battery acid. .This -biting e agement insures the easywithdrawal o the terminals when the operating handle of the improvement is rotated and the swiveled Ahead rests on the outer end of the battery pole or post. This important function of the improvementv will be appreciated by those. skilled'in the art to which my invendirected.

tion relates, and while I have. herein set forth a simple and satisfa'ctoj embodiment of my invention,.I desire it to. understood ends of the arms, pivots connecting the forks and securing the block ,therebetween, a. headed 'screw threaded through the block, a head on they outer end of the screw, a yoke surrounding the arms and pivoted to one,

of said arms, and a screw member threaded through the yoke and swivelly engaging Qwith the free arm.

t In. testimony whereof I aflix my signa-- WILLIAM a. LGILLENTINE.
