' BUDOLF SCHMID, J'B., 01 WEST ALLIS, WISCONSIN, ASSIGNON, 3! MESNE ASSIG,
'10 ALLIS-CHALIEBS MANUFACTURING COMPANY, A CORPORATION OF DELAWARE.
To all whom it may concern:
Be it known that I, RUDOLF Scrum), J r., a citizen of the United States, residingat West Allis, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Connectors, of which the following is a full, clear, and exact specification.
My invention relates to connectors for electrical conductors.
It is the object of my invention to provide a connector for electric conductors the parts of which can be readily assembled and taken apart,'said parts being held stationary with respect to each other when assembled.
The invention is illustrated on the accompanying sheet of drawings in which Figure 1 is a longitudinal sectional view of my connector; and,
Fig. 2 is a longitudinal sectional view of a modification of the connector shown in Fig. 1.
The various novel features of my invention will be apparent from the description and drawing, and will be particularly set forth in the appended claims.
This connector for electric conductors includes a sleeve 10 having a reduced portion 11 which-passes through an opening 12 in any suitable base or support 13. The re duced portion 11 of the sleeve 10 is provided with an annular groove 14 adjacent one. side of the base for the reception of r a resilient member or split ring 15, which is adapted to prevent relative movement between the base 13 and sleeve 10 when the resilient member 15 is set in place. This reduced portion of the sleeve 10 forms a shoulder 16 which presses against the base 13 and is held there by the resilient member 15. The sleeve 10 is also provided with a projection 17 which occupies a notch 18 in the base 13 to prevent turning of the sleeve within the base. Located within the sleeve 10, as indicated in Fig. 1, are two preferably duplicate interchangeable complementary conducting members or terminals 19 and 20 which are adapted to be electrically connected and held in mechanical engagement with each other by a screw 21 which passes through the overlapping portions of said terminals. This screw passes into an opening 22 in said sleeve which is sufiiciently large to receive the Specification of Letters Patent.

head 23 of the screw. The head 23 of the screw normally projects into the opening 22 of the sleeve and in this way prevents relative movement between the terminals 19 and 20 and the sleeve 10. It is therefore apparent that the screw 21 not only retains the terminals in electrical and mechanical engagement with each other, but also prevents relative movement between said terminals and said sleeve.
In the modification shown in Fig. 2 the parts are practically the same as shown in Fig. l with the exception that the sleeve 25 is provided with shoulder portions 26 which are normally engaged by cooperating shoulder portions 27 on the terminals 28 and 29. In this case the screw 30 holds the terminals 28 and 29 in good electrical and firm mechanical contact with each other and lies completely within the terminals. When this screw 30 is in the position shown in Fig. 2 relative movement between the terminals and sleeve is prevented by the cooperating shoulders 26 and 27 of the sleeve and terminals respectively.
By removin the screw and the resilient member in eit er of the connectors shown, all of the parts may be readily separated. Furthermore, when the parts are put together, all of said parts are held stationary with respect to each other.
There may be various modifications of the precise form and arrangement herein shown and described, and it is my intention to cover all such modifications and arrangements which do not involve a departure from the spirit and scope of my invention as set forth in the appended claims.
What I claim as new is:
1. A coupling for electrical conductors comprising a sleeve having a portion of uniform bore and an opening from the outside to the bore, interchangeable terminal ele ments having similar contact portions within said sleeve portion of uniform bore, and means capable of acting independently of said sleeve for connecting said terminal elements together with the contact portions in engagement, said means cooperating with said sleeve to limit the axial movementof said terminal elements relative to said sleeve.
2. A coupling for electrical conductors comprising a sleeve having a portion of uniform bore and .an opening from the outside to the bore, interchangeable terminal elements having similar contact pmtions within vsaid sleeve portion of un1formbore, a screw capable of acting indep'endentl of 'said'sleeve ,for connecting said termina tel ments with the contact portions in engagement, said screw being insertible through the opening in said sleeve, and a portion oi said screw (projecting radially outsidev the bore of sai sleeve whereby the connected terminal elements are restrained from axial changeable terminal elements having similar contact portions within the bore of said sleeve, instrumentalities for'connecting said terminal elements together with' the contact portionsthereof in engagement and for securing said elements against lon' 'tudinal movement relative to said sleeve w ile said elements are connected together, said instrumentalities including a screw element insertible to operative position through the opening in said sheave, v I
In testimony whereof I ailix my signature, in the presence of two witnesses.
