CONNECTING-CLIP FOB ELECTRICAL CONDUCTOBS.
Specification of Letters Patent' Patented Apr. '3, 1914.
continuation of application Serial No. 721,528, filed September 21, 1912. This application filed June 20, 1913. Serial 110.774.,828.
To all whom it may concern:
Be it known that I, JOSEPH H. BREAZNELL, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Connecting-Clips for Electrical Conductors, of which the following is a specification.
The invention relates to clips for connecting electric wires or conductors to bindingposts, spark-plugs, and analogous devices, and the object of theinvention is to rovide a clip of simple construction, adapte to apply upon posts of various sizes, and to insurereliable electrical contact therewith and with the connected wire, and which may be easily secured to the post and to the connecting wire.
The invention consists in certain novel features and details of construction and arran ementliywhich the above objects are atta ned, to be hereinafter described and pointed out in the claims.
The accompanying drawings form a part of this specification and show an approved form of the invention. v
Figure 1 is a plan view of the improved clip in the closed condition and carrying a connected wire conductor. Fig; 2 is a similar view with the clip-members in the open condition and the wire conductor omitted. Fig. 3 is a side or edge view corresponding to Fig. 1. Fig. 4 is a vertical longitudinal section-,taken on the line 4=4 in Fig. 1, with the wire conductor omitted. Fig. 5 is a front elevation corresponding to Fig. 1.
Similar letters of reference indicate .the
same parts in all the figures.
' The clip comprises two plates or members stamped or otherwise formed of sheet metal, preferably phosphor-bronze, having the desired resiliency or spring, applled face to face and pivoted together to be partially r0- tatable one upon the other. One, which for convenience of description is termed the upper plate, is. marked A, the lower plate, B, and the pivot, C. The latter is preferabl in the form of an eye1et.
11 one end of the plate A and lying approximately in the plane thereof, is a curved hook A and on the plate B is a corresponding but oppositely presented hook B both formed integrally with their respective plates and so arranged as to open, as in Fig.'
2, for attachment to a post, not shown, without removing the binding-nut for the latter, and to be closed to form a circular opening in which such post is embraced. The terminals A B of the curved hooks overlap in the closed condition so that longitudinal strains on the plates will not disengage the hooks from the post. The hooks are each bent slightly out of the plane of the plates, the upper hook A upwardly and the lower ,hook B downwardly so that the hooks are separated or spaced apart when free, but when a post is engaged and its nut screwed .firmly down the hooks are pressed together and! by their resiliency tend to hold the nut against unscrewing. This eflect is aided by the-engagement of the edges of the curved terminals A B. On an extension of. the plate B opposite its hook B is an open longitudinally extending tapered socket B formedby bending up the side margins of the plate to form curved flanges, within and between which is received the end of a cable wire conductor D doubled or folded upon itself to form a loop D which projects from the large end of the socket and by reason of the doubling is held against withdrawal through the small end. The extension or end of the upper plate A, adjacent to the large end of the socket B is bent u wardly and angularly to form an inclined ange or cam A which in the act of closing the clip, rides upon and compresses the extremity of the loop ,D and thus aids to insure the desired electrical contact;
B is an upwardly projecting spur or tongue formed on the center line of the-plate B near the large end of the socket B and within the latter, serving to engage the bight of the loop D and prevent the withdrawal of the loop under the tensile strains to which it may be subjected, and also to maintain the loop in position to be clamped upon by the cam A.
Instead of the eyelet C other forms of pivots, as a simple loose rivet, may be employed, but it is important that the head or hearing portion of such fastening be of large area so that the tendency of the plates to tilt or separate under the lifting action of the cam A, and the compressing action of the nut on the hooks A B, will be strongly resisted, and permitted'only by the resiliency of the parts.
The clip thus constructed is highly efli 1 cient and easily applied and connected. The several portions of each plate are produced and shaped integrally with such plate by suitable dies, and the work of assembling consists simply in joining the plates by the eyelet C, thus permitting the clip to be manufactured economically.
The present application is a continuation of my application Serial No. 721,523 filed September 21, 1912.
I claim 1. A connecting clip for electrical con ductors, comprising a pair of hook-shaped clipmembers of spring material, and a pivot connecting the said members with each other, the hooks of the members being adapted to encircle one of the conductors and the terminals of the hooks overlapping each other and being inclined in opposite directions, whereby they will be spaced apart.
2. A connecting clip for electrical conductors, comprising a pair of hook-shaped clip members, and a ivot connectin the said members with eac other, the hoo s of the members being adapted to encircle one of the conductors, and make electrical contact therewith, the said clip members. having extensions opposite said hooks, one of said extensions having means for engaging a second electrical conductor, and the other extension having a cam in position to press upon and make electrical contact with such second conductor when the members are in the closed condition.
3. A connecting clip for electrical conductors, comprising a pair of hook-shaped clip members, and a pivot connecting the said members with each other, the hooks of the members being adapted to encircle one of the conductors and make electrical contact therewith, the said clip members having extensions opposite said hooks, one of said extensions having a tapered socket adapted to receive and hold a loop of a second electrical conductor, and the other extension having a cam in position to press upon and make electrical contact with such loop.
4. A connecting clip for electrical conductors, comprising a pair of hook-shaped clip members, and a pivot connecting the said members with each other, the hooks of the members being adapted to encircle oneof the conductors and make electrical contact therewith, the said clip members having extensions opposite said hooks, one of said extensions having a tapered socket adapted to receive and hold a loop of a second electrical conductor, and an upturned tongue formed integrally with such extension and arranged to lie in the bight of such loop, and the other extension having a cam in position to. press upon and make electrical contact with such loop.
5. A connecting clip for electrical conductors, comprising two plates of spring material pivoted together face to face, hooks onsaid plates formed integrally therewith and adapted to embrace a conductor between them, the terminals of said hooks overlapping one upon the other and being inclined from each other, whereby they are spaced apart, a tapered socket formed integrally at the opposite end of one of said plates, adapted to receive and hold a loop of a second electrical conductor, an upturned tongue 'formed integrally on such plate within said socket, arranged to stand in the bight of such loop, and an inclined flange formed integrally on the other of such plates, in position to press upon and make electrical contact with such loop when said hooks are in the closedcondition.
In testimony that I claim the invention above set forth I afiix my signature, in presence of two witnesses.
