BATTERY-TERMINAL REMOVER.

Specification of Letters Patent.

Patented July 9, 1918.

To all whom it may concern:

Be it known that I, HIRAM Vi. Sarrnns, a citizen of the United States, residing at Aberdeen, in the county of of South Dakota, have invented new and useful Improvements in Battery-'lerminal Removers, of which is following is a specification.

This invention relates to improvements in terminal removers for storage batteries and the like and has particular application to a device for removing conductor terminals from binding posts of the type used on the W'illard storage battery.

As is well known, the conductor terminals in the binding posts corrode more or less and have a tendency to stick in the binding posts and the usual method of removing the terminals of the conductors from the binding posts is to loosen the set screw and drive the terminals out of the binding post by means of a hammer or similar tool. lhis method of removing the conductor terminals from the binding posts results in the muti lation of the terminals as well as the binding posts and it frequently happens that the rubber casing of the battery is broken or fractured and the plates loosened in the battery, thereby shortening the life of the battery and doing other injury thereto.

In carrying out the present invention, it is my purpose to provide a terminal remover for storage batteries whereby the terminals may be forced out of the binding posts under pressure without the use of a hammer or,similar tool and whereby the terminal will be removed from the binding post gradually and without shock or jar to the battery, thereby eliminating the mutilation of the binding post andterminal and preventing cracking of the battery case and loosening of the plates.

It is also my purpose to provide a terminal remover of the class described which may be applied to the storage battery quickly and conveniently and which may be operated readily and with a minimum cliort on the part of the operator, thereby enabling the terminal to be removed from the binding post with ease and facility.

Another object of my invention is vide a storage battery terminal which will embrace the desired features of durability, which simplicity, eliiciency and kit, or about the may be carried in a tool Brown and State person and wherein the component parts will be so arranged and correlated as to reduce the possibility of derangement to a minimum and enable such parts to be repaired or replaced whenever necessary.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts here inafter set forth in and falling within the scope of the claims.

In the accompanying drawings:

Figure 1 is a view in elevation of a battery terminal remover constructed in accordance with the present invention, the same being shown in use.

Fig. 2 is an edge view of the terminal remover.

Fig. 3 is a top plan view thereof.

Fig. l is a vertical sectionalview therethrough.

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 1.

Fig. (i is a similar view on the line 6-6 of Fig. 1.

Fig. 7 is an enlarged fragmentary vertical sectional view on the line 77 of Fig. 1.

Referring now to the drawings in detail, 1 designates a storage battery, while 2 indicates the binding posts connected to the terminal posts of the plates of the storage battery. In the present instance, each binding post 2 comprises a block 3 formed with a transverse opening 4 gradually decriasing in diameter from one end toward the other. 5 indicates the terminals of the conductors and those terminals are shaped after the fashion of the openings 4 in the resprrtive blocks 3 and each has the end thereof formed with a threaded bore 6 in which is threaded a set screw or clamping screw 7. After the terminals 5 are passed into the openings l in the blocks 3, the set screws 7 are thrrndcd into the bores 6 and the heads of the screws bear against the adjacent edges of the blot-ks to draw the terminals into the openings so as to form a good electrical connection between the binding posts and the terminals whereby the current from the battery may flow through the conductors My improved terminal remover is indicated as an entirety by the ninneral 8 and, in the present instance, comprises legs 9, 9 spaced apart in parallelism and having the extremities flu-roof atone end of the device formed with a yoke 10 and block ll respecllll votally tively adapted to engage one edge: of the block 3 of the binding post and the outer end of the set screw, the yoke 10 surrounding the terminal 5, clearly illustrated in Fig. 1 of the drawings. 12 designates a longitudinally curved bar having the inner edge thereof formed with grooves 13 adja cent to the respective ends of the bar and formed on the side walls of each groove 13 are beads 14:. This bar 12 is mounted upon the other ends of the legs 9 and the ends of the legs are disposed within the grooves 13 respectively and the opposite sides of each leg are formed with grooves 15 that receive the beads 14 so as to hold the bar 12 against accidental removal from the legs and permit sliding of the ends of the legs within the grooves 13. Formed in the bar 12 centrally thereof is an opening and mounted within the opening is a bushing 16. Threaded through the bushin r 16 is a screw shaft 17 arran ed between the legs 9 and having one end t ereof terminating short of the firstmentioned ends of the legs and the other end terminating ad acent to the outer edge of the bar 12. The threads on the shaft 17 extend from the last-mentioned end thereof to a point approximately centrally of the length of the shaft and formed in the shaft 17 adjacent to the center thereof and to the first-mentioned end are grooves 18, 18 respectively and surrounding the grooved portions 'of-the shaft are collars 19 each ormed, at diametrically opposite points, with outwardly projecting pivot cars 20. Pivoted within the cars 20 on the collars are the inner ends of links 21 respectively and the outer ends of the links 21 are pivconnected to the adjacent portions of the legs 9. The links 21 adjacent to the bar 12 are relatively long and normally diverge upwardly and outwardly from each other, while the other links 21 are normally arranged horizontall Formed on the outer end of the shaft 1 is an angular head 22 having the inner edge formed with an outwardly projecting shoulder 23. 24: designates a socket member adapted to fit over the head 22 and shaped to conform to the configuratioirof the head and pivoted upon the outer end of the socket member 24 is a handle 25, while formed integral with the socket member is a ratchet disk 26. livoted upon the handle 25 is a double ended pawl 27 having the ends thereof capable of interchangeable engagement with the ratchet disk 26 so that the disk, the socket membeiaand the shaft 17 may be rotated in one direction or the other. Secured to the *llltl' edge of the bar 12 and projecting outwardly therefrom are pairs of pins 28 disposed at opposite sides of the shaft 17 respectively. 29 designates a handle formed, :uljacent to one end, with openings 30 adapted to receive the pins of either pair 28 and capable of interchnngeablc association with such pins so that the device may be held against bodily turning movement in the rotation of the shaft 17 under the action of the handle 25 and pawl and ratchet mechanism.

In. practice, the yoke end 10 of the leg 9 is placed over the terminal 5 and engaged with the block 3 of the binding post, while the block 11 on the other leg 9 is engaged with the head end of the set screw 7 after the latter has been loosened. The device is held in place by the handle 29 and the shaft 17 rotated under the action of the pawl and ratchet mechanism and the handle 25. In the rotation of the shaft 17, such shaft is drawn upwardly with the effect to spread the upper links 21 and draw the lower links 21 toward each other, thereby swinging the binding post ends of the legs 9 together and spreading the other ends of such legs, the last-n'ientioned ends of the legs riding in the grooves 13 in the inner edge of the bar 12. In this swinging of the arms 9, a, pressure is exerted upon the set screw 7 and the terminal 5 with the effect to force the terminal out of the opening 4 in the block 3 of the binding post.

It will be seen that the terminal isthus quickly and easily detached from the binding post without the use of a hammer or other instrument, while practically no strain is placed upon the casing of the storage battery or upon the plates.

While 1 have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention.
