2 Claims.

Our invention relates generally to means for connecting conductors such as wires and cables to difierent types of electric batteries, such as storage batteries, air cells, dry cells, and particularly to a single connecter which is arranged to be capable of being efiiciently connected to the diiferent types. and sizes of terminals of different classes and types of batteries; and an important object of our invention is to provide a simple and eflicient device of this character which can be manufactured very cheaply.

Another important object of our invention is to provide a device of the character indicated which can be very quickly and easily applied and removed from the battery terminal and so as to make an efficient electrical connection therewith.

Other important objects of our invention will be apparent from a reading of the following description in connection with the drawing, wherein for purposes of illustration we have shown a preferred embodiment of our invention.

In the drawing:

Figure 1 is a side elevational View of a portion of a storage battery of the size which is used in an automobile and showing the device of the invention connected to a terminal thereof.

Figure 2 is a top plan view of the device.

Figure 3 is a longitudinal vertical sectional view taken through Figure 2 approximately on the line 3-3.

Figure 4 is a transverse vertical sectional view taken through Figure 2 approximately on the line l4.

Referring in detail to the drawing, the numeral 5 generally designates the device of the inven tion which includes the tapering base 6 in the form of a flat metal plate having in its wide end a hole 1 of suificient size to receive the battery terminal 8 of the storage battery 9. In the middle of the top of the plate 1 is a sliding latch I which slides in inverted L-shaped guides H and I2, toward and away from a hole l3 which is formed through the plate 6 to receive the smaller terminals of the small storage batteries and dry cells. The end of the latch in remote from the hole I3 has two upstanding lugs It acting as handles for retracting the slide against the action of the spring l which has one end coiled about a lug l6 on the end of the latch l0 and about an L-shaped standard I! at its oppo- N. Dak.

site end, the standard I! rising from the top of the base as clearly shown in Figure 3. It is obvious that when a terminal has been entered in the hole l3 and the latch l0 released the sharp edge of the latch will engage the terminal and push the same against the opposite side of the hole I3 and thereby firmly electrically engage the terminal and hold the plate 6 thereto.

At the small end of the plate 6 is a hole l8 which receives the bolt 1! 9 which includes a binding post 26 for connecting a cable 2| in the manner indicated in Figure 1. The bolt has below and engaging the bottom of the plate 6 the head 22 to which the upper end of a helical expanding spring 23 is connected, the said spring having its lower end connected to a second head 24 which is adapted to rest on the top of the battery as indicated in Figure 1.

It is obvious that when the plate 6 has been applied to the large battery terminal as shownin Figure 1, the spring 23 being compressed in the act, upon release of the plate 6 the same will swing upwardly under the impetus of the spring 23 so that the edges of the opening 1 will dig into the sides of the battery terminal 8 and thereby make a firm electrical connection. Simply depressing the small end of the plate 6 and putting the plate 6 back into a horizontal plane will permit releasing the edges of the opening I from the battery terminal 8.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts within the spirit of the invention and scope of the subjoined claims.

Having thus described the invention, what we claim as new is:

1. A battery connecter of the character described, comprising an elongated plate provided with an opening in one end portion thereof completely enclosed by the material of the plate for receiving a battery post, said plate being provided with a depending coil spring at the opposite end thereof adapted to engage the top of a battery at its lower end to tilt the plate when the post of a battery is disposed through the opening so that the edge portions of the plate .at the opening will bite into the post andrneans on the plate whereby a conductor wire can be connected thereto.

2. A battery connecter of the character described comprising an elongated plate provided with an opening in one end portion thereof completely enclosed by the material of the plate, said plate being provided with a depending coil spring at the opposite end thereof adapted to engage the v 10 top of a battery at its lower end to tilt the plate when the post of a battery is disposed through the opening so that the edge portions of the plate at the opening will bite into the post, said last mentioned end of the plate having a binding post disposed therethrough and to which the spring is secured, said binding post being provided with a nut thereon whereby a conductor can be clamped between the nut and the plate.
