, the accompanying drawing and described in the following specification, and it is more particularly pointed out in the appended claims. In the drawing, Fig. 1 is a plan view of one form of clip embodying the present invention, parts be in broken awa p Fig. 2 is a side elevationof the device in F igi 1. 1
Fig-3'is'a section on line:33of Fig. 1. I Fig. 4 is a fragmentary View of the device shown in Fig. 1 as applied to a screw or rod. Fig.1 5 isa View similar to Fig. 1, showing a, somewhat modified form of the invention. Fig. 6 is a section on line 6-6 of Fig. 5. Many kindsof electrical construction and operation. require a conveniently operated shown means for providing electrical contact between a conductor and some form of terminal member. Spring clips have been heretoforeused for this purpose, but 111 the forms previously employed ditficulty has been experienced insecuring convenient and efficient connection between the conductor and clip andlini connecting the clip tQSOIflQfOIfmS of terminals. The presentjinvention provides improved means for securing these results.
The numeral 10; designates an electr cal conductor such as an nsulat oncover'ed WIFE.-
Thisfconductoris secured to one of the jaws 11 of a'spring clip, the opposite jaw 12; of
whicliis pivotally connected to the jaw ll'bymeans of ears 1 3 and a pivot pin ll. A:he1i'-,
1922: Serial no. 594,744.
the spring .15 is shaped to form aneye 19 to I which a tongue 20 is pivotallyconnecte'd by means of airivet 21. Thisrivet: permits lat-j eral movement of the tongue 20, but holds the spring and tongue against relative move ment in avertical direction as v ewed in Fig. 2. The I'.Sll16IlvC-y"Of the spring 15 presses the tongue 20 into the channel formed by the members l'? and 18' so that the conductor 10 is resiliently pressed against thebottom, of the channel. and-thus held" in place, at the, same time forming electrical contact with theclip. The tongue 20 maybe made of a pieceot Wire bent upon itself, the parts being solderedor otherwise securedto onetanother where they come into contact. The free end of the wire may be bent downwardly to provide a point.
22around which the conductor '10 is looped toprevent its being withdrawn from the channel 17. The tongue 23 maybe struck inwardly from the jaw llto form a further anchorage for the conductor 10 ifitis found desirable.
For connecting heavy conductors it: .is sometimes desirable to provide a positive clainp- 'for pressing the tongue 20 against the conductor in addition to the force of the spring 15. This maybe done by extending an ear 24: upwardly'from'the side 18 for supporting the screw 25 in positionto bear upon the top of the tongue 20, as shown in Figs. 2 and 3. Screws 26 may also be threaded through the sideofthe channel shank 27 to clamp the conductor lOQfroin opposite sides. where this-is found desirable. The end; of the channel shank 17 may be closed by a web .28; having an opening therethrough as shown at 29, Fig.2, for the passageof the 12; These openings are provided, with outmadly, struckicollars 31v which are slightly;
out of alignment when the jawsare closed, but which are brought into alignment when the jaws are open, as shown in Fig. 4. To connect the-device with a cylindrical terminal 32 the jaws are opened as shown in that figure and the openings 80 are slipped over the cylindrical member. WVhen the jaws are released they will tend to return to their closed position and the collars 31 will bind closely against the terminal with a wedging movement that will provide a firm connection and good electrical contact. Asv shown in Fig. 1, the ears 13 may be held together by hollow rivets 33 through which the pivot pin 14 passes. The rivets 33 will retain the jaws in'as'sembled relation irrespective of pin 14:. Thisfis of material assistance in assembling the parts, since it is a diiiicult matter to hold the openings in the ears 13 in alignment and j the coiled spring 15 so compressed as to permit insertion of the rivet 1 1. Where hollow rivets33 are used, however, this operation is rendered less difficult, as the jaws are' first secured in proper relation and the spring 15 is the only part-that then requires attention at the same time that the pin 14: is inserted. g
In the form of the'invention shown in ingthe conductor 10 in place. Ihis arrangement will usually be found satisfactory where light conductors are employed. The
It will be seen that this removal may be readily accomplished by lifting on the loop 34 at the end of the tongueuntil it is free of the sidewalls 18"and then swinging the thus holding the conductor securely without the use of: solder-or other attaching .mate
rial whichisdiiiicult to-apply and requires special equipment.
lhesame operation may be performed with the form of clip shown in Figs. 5 and 6,
the lateral movement of the tongue 20 being permitted by the resiliency of the wire from which the spring 15 is formed. i
- For a very heavy construction the pivot 21 makesa more convenient arrangement, but
The shank 17 is perforated to perthe lower jaw to the battery terminal and leave the upper jaw free to be operated to grasp a loose conductor. A similar result can be secured by throwing the extension 20 of the spring to one side and removing the conductor 10 from its socket. The opening 29 may then be placed over the battery terminal and the nut screwed down upon the web 28, the nut being arranged in the socket for the conductor 10. This may be 111016 readily effected by placing'the nut within the socket and clamping it in position by the screws 25 and 26 after which the entire devicemay be screwed to the battery terminal.
In place of using a nut in the socket the bat tery terminal may be passed through the opening 29 and clamped in place by the threaded members 25 and 26.
