UNITED STATES PATENT OFFICE onARnrs E. TaYLoR, or LOS ANeELE's, cAmRoRnIA, ASSIGNOR To TAYLoR BROTHERS mnURAcTnRme CORPORATION, T ELKHART, mourns, a CORPORATION or INDIANA BATTERY TERMINAL ctmr Application filed June 18,

. My. invention relates to battery terminal clamps for securing electric cables or conductors to the terminal posts of storage batteries. I

The objects of my invention are: first, to provide a clamp of this class which may be easily and quickly rigidly secured to a battery terminal 0st, and also easily and quick- 1y disconnecte and removed therefrom; second, to provide a clamp of'this class which will not be distorted when securing the same to the post, and again distorted in the opposite direction when removing the same from the post; third, to provide a clamp of this class whereby, when the clamp is secured to or removed from the battery terminal post, the usual distorting or twisting force on the post or the shocks caused by pounding against the clamp, is reduced to a minimum, thus materially increasing the life of the battery and the casing therefor, as well as leaving the posts free from mars and burrs; fourth, to provide a clamp of this class whereby substantially the whole of the battery terminal post is surrounded by the clamp, thus providing a greater-grip thereon, and also" reducing the likelihood of cor-- rosion of the post and the marring thereof to a minimum; fifth, to provide a clamp of this class which is very light of construction but very strong; sixth, to provide a clamp of this class which is composed of several clamp members, but so connected as to form a unitary clamp and further so connected that the parts cannot be readily se arated, and further so connected that w en a battery terminal post is clamped, the

several parts will not be distorted; seventh,

to provide a particularly simple and economical means and method of connecting two slidable members of the clamp together; and, ,eighth, to provide as a whole a novelly constructed clamp of this .class and one which will not readily deteriorate or get out oforder. i I

With these and other objects in view, as will appear hereinafter, my invention consists of certainnovel features of construction, combination and arrangement of parts and portions, as W'lll. be hereinafter de- 1928. Serial No. 286,427.

scribed in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure l is a top side view of my battery terminal clamp in its preferred embodiment, showing the same as it appears from above when the same is secured to a battery terminal post; Fig. 2 is an end viewthereof taken from the screw end of the clamp; Fig. 3 is another end view thereof taken from the cable end thereof; Fig. 4 is a longitudinal sectional elevational view thereof taken through 4'4 of Fig. 1; and, Figs. 5 and 6 are transverse sectional views thereof taken, respectively, through 55 and, 6-6 of Fig. 1.

Like characters of reference refer to similar parts and portions throughout the views of the drawings.

The preferred embodiment of my battery terminal clamp, as illustrated in the drawings, consists of a stationary battery clamp lower to the upper side. At one end of the member 1' is a seat ortion 1b o f,substantially semi-circular orm at the inner side of which is-provided a semi-circular recess ,10 which is tapered convergingly upwardly from thev lower to the upper side of the -member 1 forming a tapered semi-circular seat'for receiving one side of a tapered or frusto conical battery terminal post, shown by dotted lines and designated A in Fig. 4. From the opposite sides or ends of' the semicircular portion 11), extend' arms or straps 101 which form the opposite sides of the longitudinal opening 1a The extended ends of the arms or straps 1d are connected by a cross member or portion 1a which forms the end wall of the opening 10. opposite ;the end provided with the semi-circular recess 10. The portions 1?), 1d and 1e are preferably molded together as an integral unit, as shown;

In the openin 101 is positioned the movable clamp member 2, which extends trans versely across theopening between the arms onstraps 1d and is reciprocally mounted in .alongitudinalfdirection therein on the arms or straps 1d. The opposite lower and upper edges of the inner sides of the arms or straps 1d are beveled forming longitudinally extending recessed guide portions or ledges 1f I ridges orledgxes inwardly from the lower and upper sides of the member 1. At the lower and upper edges of the opposite ends of the clamp.

member 2, are provided outwardly or laterally extending ridges orledges 2a and 2?),

respectively, which ridges or ledges are beveled at their adjacent inner sides at an angle corresponding with'the beveled ledges 1f.

h'ese ridges or ledges ride upon the beveled led es 1 and form retainin portions for hol g the member 2 in position relative to the member 1 against removal and in guiding relation therewith. "The lower scribed, but t e up er ridges or ledges 2b are formed by swedgin upwardly extending portions, shown by otted lines and designated in Fig. 6, downwardly and outwardly, after the member 2 is placed in the position shown, against the upper beveled The inner side of the member 2 adjacent the seat 1c is also provided with an upwardvided,

lytapered semi-circular'seat 203 which is adapted to engage the opposite side of the battery terminal 'post.

- The seat portions 10 and 2d are clamped against the opposite sides of the battery terminal post by the screw 3 which may be an ordinary set screw. This screw extends through a boss '19 at the outer side of the cross portion 10 and extends into the opening 1w at-its longitudinal axis, engaging at its-inner end the side of the clamp member 2 opposite the seat portion.

On the stationary clamp member 1 is propxreferably by molding integrally therewit a cable connectingpost, or socket, 170; of any suitable construction for connecting an electric cable or conductor thereto.

.This connecting portion lit-may be either extended from the and of the member, 1 in alignment with the longitudinal axis of the member 1, or,from the side thereof, or there-- from at anangle.

It will be here noted that the material of which theseveral members are made is preferably a non-corrosive metal so as to reduce binding of the several members together to a minimum.

It will be also noted that the construe:

tion of the clamp, as shown, is such that the samemaybe utilized either on the positwo or negative post of thebattery, and

2a maybe molded, as de-- ismase may be used either as a right or left hand clamp.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is:

1. In a battery terminal clamp, a'clamp member having a longitudinal opening therein and longitudinal recessed guide portions at the opposite lateral sides of said opening and at the opposite sides of the clamp member, and a movable clamp member positioned 'in said opening transversely therewith and reciprocally longitudinally therewith, theopposite ends of the movable clamp member being provided at the opposite sides thereof with outwardly extending retaining portions adapted to extend into the longitudinally extending recessed guide portions of the first clamp member and positioned substantially flush with'the upper and lower sides thereof engaged by the movable clamp member, for preventing removal of the movable clamp member from the latter.

- 2. In a battery terminal clamp, a clamp member having a battery terminal post seat near one end, a connecting portion at its opposite end and arms connecting the opposite sidesiof the seat portion with the opposite end of the connecting portion, forming a longitudinal opening in said member, the opposite edges of the'sides of the arms forming the longitudinal opening being beveled from the cross portion to the seat portion, and a movable clamp member extending transversely across the opening and recipro cal longitudinally therein, the opposite ends arms.

3. A battery terminal clamp comprising a clamp member having a longitudinal opening therein, said opening extending through the upper and lower sides of the clamp member, a movable clamping block positioned insaid opening transversely thereto and reciprocally movable longitudinally thereof,

the ends of the clamping block being-relatively wide and flat and positioned in substantial engagement with the inner side walls at the laterally opposite sides of the opening and in such manner relative thereto as to prevent turning of the block relative to the first mentioned clamp member, said clamping block having at its upper and lower sides retaining ledges extending beyond the aforementioned ends and engaging the upper and lower portions of the clamp member at the opposite sides of said opening,
