Specification of Letters Patent;
Application filed December 9, 1920. Serial 1T0. 429,435.
' following is a specification.
clamp :bowed transversely, as shown at 13, to form This invention relates to devices for making electrical connections, and more particularly to devices of this kind applicable to the ends of conductors, the object of the .inven tion being to provlde a very simple, strong and efiicient connector which can be readily applied.
. he object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.
In the drawing Figure 1 is a side elevation of one form of the device; Fig. 21s a lan view thereof; Fig. 3 is an end View; F1g. 4 is a side elevation showing another embodiment of the invention; 'Fig. 5 is a plan view .thereof, and Fig. 6 is an end view.
The device shown in Figs. 1, 2 and 3 of the drawing comprises a split sleeve 10 having .an integral arm 11 extending lengthwise from one o'f'its ends and carrying a cam 12. The outer end of the arm 11 is a seat for a conductor wire, and it is also formed with upturned ears 14 between which the cam 12 seats and to which it is pivoted as shown at 15. The cam 12 isprovided with a handle extension 16, which is connected to the arm 11 by a spring 17 tending to swing the cam to gripping position.
The insulated wire with which connection Y is to be made'will have its end embedded in the sleeve 10 and its bared end soldered to the arm 11. The other wire will be seated in the trough-shaped end 13 of the arm 11, and upon swinging the cam 12 to grip said wire, the latter is securely held, the sprinIg 17 keeping the cam in gripping position. t
- will also be evident that the harder the wire is pulled, the tighter it will be gripped by the cam.
' The device shown in Figs. 4 to 6 comprises 'a base plate 18 having a cam 19 at each end the same being similar to and operating in the same manner as the cam 12. The ends of the plate 18 are reduced and made bowed in cross-section as shown at 20 to provide seats for two wires.
I. median line ofthe arm 11 so as to be entirely clear of the wire which is to be soldered to the arm. This arrangement also places the spring 17 out of the way of the wire, as well as out of the way of the projecting inner end of the wire gripped by the cam 12, and keeps the device within reasonable dimensions.
An electrical connector comprisingamemher having means for connection with a conductor, said member having an integral arm extending lengthwise from one of its ends, the outer end of the arm being bowed trans versely to form a seat for a second conductor, and having upturned laterally spaced ears at its sides, a cam clamping member seating between the ears and pivoted thereto for engagement with the second-mentioned conductor, said cam having a rearwardly projecting operating handle extension 0- sitioned above the aforesaid arm ando set laterally with respect to the longitudinal median line thereof, and a spring connected to the handle extension for swinging the cam to gripping position.
In testimony whereof I aflix my signature.
