TRIP/[MING TOOL.

Application filed November 1. 1926.

This invention relates to and has for a main object the provision of an improved type of tool which is adapted for cleaning the surface of storage battery terminals such as are used in motor cars and in connection with radio sets, and for other purposes, whereby the terminals which generally corrode to a large extent can be cleaned and resurfaced quickly and nicely.

Another object is to provide an improved type of tool over that shown in my pending application for trimmers,- filed Oct. 19, 1926; Serial Number 63,346.

It is a further object of the present invention to provide an improved tool having.

the general form and characteristics of a pair of pliers, arranged with a trimming tool mounted on one of the handles thereof, and provided with a tapered cutting edge termed so as to embrace a battery terminal in such a manner that the cutting edge will be resiliently held against the tapered ter minal, and will conform itself to the size the terminal, whereby when rotated about the terminal the outer surface thereof will be trimmed preparatory to attaching the usual connectors thereto.

Another object is to provide in a tool of the character described, in connection with a pair of pliers for supporting the tool on the handle thereof, aws formed on opposite ends of the plier halves and provided with nut receiving notches, whereby the same tool may be employed as a wrench for removing and attaching nuts from and to the connector bolts, respectively.

Other and more detailed objects of invention will appear as the description progresses.

I have shown a preferred embodiment of my invention in the accompanying drawing, in which:

Fig. 1 is an elevation of a battery with a terminal thereon, and my improved tool shown in operative relation thereto.

Fig. 2 is a substantially full-sized view of my complete tool.

Fig. 3 is an enlarged side view of the wrench awe of the same.

Fig. 4 is a transverse sect-ion on line 4:4: of Fig. 1; and

Fig. 5 is a perspective view of the trimming tool attached to the pliers shown in Fig. 1.

In the consideration of this invention, it will he understood that the usual battery terminals t are of larger diameter at their lower Serial No 145,485.

extremities than at their upper extremities, in order that connectors of different size, by means of which the wires are attached to the battery, may be frictionally held on the terminals. Accordingly, I have provided a tool which is tapered corresponding to the taper of the terminals 5', and formed of tempered spring steel provided with a, single cutting edge at the end of an arcuate portion, which is formed on a radius less than the radius of tl e terminal 75.

The terminal trimming tool is adapted to be mounted on a well-known form of tool, as shown in Fig. 1, composed of substantially like portions A. and A, with enlarged body portions a and a respectively, pivotally held together by means of a rivet or bolt P, and formed with extended handles H and H and jaws J and J, respectively, on opposite sides of the pivot P.

The trimming tool T is formed of a single piece of tempered spring steel, with a slightly curved attaching portion 6, having perforations 0 therein adapted to abut the end of the handle H or H, and to be secured thereto by means of one or more rivets or screws, as at r. The slightare formed in the portion B of said tool serves substantially as a lock washer so that the tool T will be held in tension and against accidental removal from the handle H;

Forwardly of the portion 7) a short extension 9 is provided which flares outwardly to a slight extent, and on the opposite side portion I; is continued in a side portion cl, which joins with an arc-uate portion 7 formed on a radius which is less than the radius of the terminal t. The arcuate portion f terminates in a cutting edge e, which is substantially spaced from the'edge e of the portion 9 and is adapted to engage the outer surface of the battery terminal 6 when the device is in use.

The cross section of the tool T, as shown in Fig. 4,- is such that the terminals t will have a bearing on the portion d at a point on the periphery of the terminal 25 and also at other peripheral points on the edges 6 and e. The opening between the edges 6 and e is so positioned that said edges will touch the periphery of the terminal 25 at equally spaced points from and on opposite sides of a transverse line cutting the axis of the terminal t, as indicated in Fig. 4, while the arcuate the surface of the terminal as will also be the attaching portion 6. The portions (Z, 7, and g of the tool T are tapered throughout the length thereof so that the tool at the bottom will be of slightly larger area than at the top, 7

the taper thereot conforming, as herein stated, to the taper oil' the terminal 6.

As shown in Fig. l the pliers comprising the pivotally connected portions A and A are held in the hand vertically, and the tool I is forced downwardly over the terminal 6, the resiliency of the tool serving to spread the edges 6 and e apart the tool is moved downwardly over said terminal. Thereafter the tool may be rotated in a clockwise direction as seen in Fig. 4, so that the cutting edge 6 will be resiliently held in engagement with the periphery of the terminal t, and serve to cut away the corroded substances and provide a clean surface for the reception of an ordinary battery terminal connector, whereupon the tool may be removed by pulling the same upwardly and the resiliency of the tool will effect a complete restoration of the tool to normal shape.

Connectors such as are used on battery terminals are usually provided with bolts for frictionally holding the connectors on the terminals, and it is necessary in order to remove the same from or attach the same, to remove or attach nuts, as at N in Fig. 3, from said bolts. It is desirable, therefore, that a tool for resurfacing the terminals should also be provided for removing and attaching said nuts, and to th' s end I provide on the jaws J and J, respectively, of the plier members A and A, cooperating and similarly formed nut receiving portions which are provided internally with a series of serrations or notches a, 41., etc. These notches are so arranged and disposed with respect to each other, andarc of such size that the corners Z, Z, etc, of the nut will seat in the notches, while the facets 2, 2, etc, are disposed on lines as shown in Fig. 3.

Hexagonal nuts being common use, the normal size and i rrangelinent off the notches m is such that the corners Z, Z, etc, will engage certain of the notch when the nuts are in a certain position, antL other of the notches when the nuts are in still other positions. Thus, it will be observed that when the batteries are inaccessibly or inconveniently positioned so as to a l'lord access to the nuts, it is quite difficult, it not impossible, by the use oi an ordinary wrench to move the nuts on the bolts, while the jaws J and d" formed as shown, the notches m will engage the corners of the nuts irrespective of the particular position of a. nut on a bolt, so that only a slight movement of the handles H and H will be necessary to remove the nut.

It will be understood, however, that the particular form of aws J and J are not material to the particular form of the tool T, and it is further conceived to be possible to modify the form of the trimming tool from that shown without departing from the spirit of my invention,

What I claim is:
