TERMINAL CLIP.

Application filed June 19, 1922. Serial No. 569,443.

To all whom it may concern:

Be it known that I, l/VALTER W'. DAIKER, a citizen of the United States, residing at Brooklyn, in the countyof Kings and State of New York, have invented certain new and useful Improvements in Terminal Clips, of which the following is a specification.

This invention relates to terminal clips and the primary object of the invention is to provide a novel clip for receiving the terminal of an electric wire which is so constructed that the said wire can be easily and expeditiously placed in connection therewith and prevented from being accidentally displaced therefrom.

Another object of the invention is to provide a terminal clip formed of a single strip or ribbon of resilient metal embodying novel means for engaging the wire, which will tend to grip the wire tighter as the tension onthe wire is increased, thereby preventing the accidental withdrawing of the wire from out of engagement with the clip.

- A further object of the invention is to provide a novel terminal clip for engaging different sized electric wires of di ferent types, such as small or large solid single wires or stranded flexible wires, which is so constructed as to bite into and clean the wire for insuring a positive contact.

A further objectof the invention is to provide a terminal clip which renders the necessity of twisting or coiling the wire about a post unnecessary, and which permite the wire to be introduced into engagemerit with the clip at one end .thereof, thus eliminating the necessity ofbending the wire for bringing the wire into engagement with the side of a clip as contemplated by some of the terminal clips on the market.-

A further. object of the invention is to provide an improved resilient terminal clip embodying a guide for the wire, and a resilient tongue for biting into the 'wire for.

preventing displacement of the same, the clip eliminating the necessity of }providing a'long bare end on the wire, whic is liable to contact with other clips thus permitting the clips to be placed closer together, thus taking up less space,

the clip permitting a mm with [insulation mptenal. v

be employed for connecting the clip A to the thereon to be inserted'directl in the clip.

A further object ,of the invention is to provide an, improved resilient clip wh ch can be conveniently actuated by one hand of the operator for permitting the connecthe guide formed in tion or disconnection of the electric wire thereto.

A further object of the invention is to provide an improved terminal clip embodying a base, the guide body extending upwardly fromthe base having a guide opening therein for receiving the electric wire and its insulation, a resillent tongue formed on the guide body for engaging the bare portion of the wire and for holding the same in contact with the base of the clip, and a handle for permitting the flexing of said resilient tongue, so as to ermit the easy and convenient'placing of t e wire in engagement with the clip or removal of the wire from out of engagement with the clip.

A further object of the invention is to provide an improved terminal clip of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost. With these and other objects in view, the invention consists in the novel construction, arrangement and formation of arts, as will be hereinafter more s ecifical y described, claimed and illustrate in the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is an enlarged perspective view of the improved terminal clip.

Figure 2 is an enlarged longitudinal section through the clip showing the electric wire connected therewith.

Figure 3 is an enlarged perspective vlew of a slightly modified form of the improved cli fieferring to the drawings in detail, wherein similar reference characters designate corresponding parts throu bout the several views, the letter A indicates one form of the improved form thereof. I

As shown, the improved cli A is formed of a single strip or ribbon of exible electric conducting material which is bent to rovide the longitudinally extending 'ase strip or plate 5. This base strip or plate 5 is, of course, adapted to be secured to a suitable support, plate 10, w

A set screw bolt or rivet 11 can can be inserted through a suitable openingclip; and B, another.

such as the base 'ich is formed of non-conducting 6 formed in the base strip or' plate 5 adjacent to the outer end thereof. Theinner end of the base strip or plate is provided with a right angularly disposed gulde plate or strip 7, which can be provided adjacent toits lower edge with a guide opening 8, through which the electric wire 9 can be inserted. The opposite end of the plate or base strip 5 may have means formed thereon for permitting the other terminal or electric conducting wire to be electrically connected thereto as by solder, or if so desired, the other electric wire can be electrically' connected to the plate through the medium of the screw 11 or another clip. This means formed on the opposite end of the plate 5 from the guide plate 7 consists in an upwardly extending reduced tongue 12, which can be notched as at 13 for permitting a wire to be placed therein.

The guide plate 7 extends above the upper surface of the base strip 5 to the desired distance and is then bent downwardly at.

an acute angle to the guide plate 7, to form the resilient arm 14. This resillent arm 14 extends downwardly toward the base strip 5 and terminates in relatively close proximity thereto. As shown in Figures 1 and 2 of the drawings, the resilient arm 14 has formed on its lower terminal, an upwardly extending inclined actuating arm 15, which terminates in an outwardly extending finger piece 16. This actuating arm 15 with finger piece 16 allows the convenient flexing of the arm 14 by the operator of the clip.

A tongue 17 is struck out from the resilient arm 14 and the actuating arm 15 and is normally urged into intimate contact with the upper surface of the base strip 5 by the. m herent resiliency of the arm 14. As shown, this tongue 17 lies in the same plane with the resilient arm 14.

In order to add strength and rig dityto the base strip or plate. 5, this plate at a polnt intermediate the arm.14 and the guide arm or strip 7 has struck up therefrom the longitudinally extending ribs 18 whlch lie on opposite sides of the tongue 17' andform a guide for the electric wire 9 when the same is inserted through the guide opening 8. These ribs will serve as means for effectively guiding the wire under the tongue 17 when the same. has been lifted by the finger piece 16 and the actuating arm 15.

In use of the improved clip, when it is desiredto connect a wire thereto, thefinger iece' 16 is grasped between the fingers and ifted upwardly, which will-move the tongue 17 above the up er surface of the base strip 5. The wire 9 1s then inserted through the ide opening 8 and under thetongue 17. ressure can then be released from the finger piece 16 and the tongue 17 will be forced into intimate biting contact with the wire and urge the same into frictional contact with the base strip 5. Now, it can be seen that when stress is exerted upon the wire 9, the wire will tend-to pull the arm 14 and the tongue 17 inwardly and thus bind the wire into tighter engagement with the base 5, and thus absolutely preclude the withdrawing of the wire from the clip. It is merely necessary, however, to raise the finger piece 16 when it is desired to remove the wire from the clip. As clearly shown in Figure 2 of the drawings, the Wire with its insulation can arm 14 and the tongue 17, it can be seen thatonly one edge of the end of the tongue '17 will com'eginto engagement with the wire or base plate,"which forms a sharp means for biting into the wire to prevent displacement of the wire.

In the modified form of the improved clip,

as shown in Figure 3 of the drawings, the actuating arm 15 and the finger piece 16 is eliminated. However the principle of the clip remains exactly the same, in thatit still includes theresilient arm for biting engagement with the wire which is forced into tight engagement with the. wire. as tension on the wire is increased. As shown, the modified from B includes the base strip 20 which is secured to a base block of insulation 21, by means of a screw 22. One end of the base strip 20 is provided with the upwardly extending right angularly disposed guide arm or plate 23, which is provided with the guide opening 24 adjacent to its lower end for receiving the electric wire which is to be connected to the clip. The upper terminal of.

the guide arm or strip 23 terminates in a depending inchned resilient arm 25, which is normally urged into intimate contact withthe upper surface of the base plate 5 by the inherent resiliency of the material from which the clip is formed. The resilient arm 25 is arranged at an acute angle to-the upstanding guide-arm or strip 23 and-the inner edge of the terminal of the arm 25 lies in.

facial contact with the base 20 and forms a sharp biting surface for engaging a wire which is placed under the same and into engagement with the base strip. This resilientarm 25 can have struck outwardly therefrom a fin er piece 26, which serves as means for permitting the convenient flexing of the resilient $111125, when it is desired to place an. ,electric wire under the sameor'whenit is desired to move an electric wire from under the same On each side ofthe finger piece 26, the resilient arm 25 has struck out therefrom ribs 27 which tend to'add rigidity to the plate. 7 v

The base strip'20 intermediate the arm 25 and the upstandingguide arm orstrip 23 a can have guard flan es-28 struck up" from the opposite edges thereof and these flanges form means for strengthening the base strip and act as a guardforguiding a wire under the resilient arm when the same is tiexed. The terminal of the base strip 20, which is opposite to the terminal having the upstanding guide arm,or strip 23 formed thereonv can be provided with suitable means for permitting the other electric wire tobe rigidly connected thereto. If so desired,- another clip can be employed for this purpose.

The modified form of the clip B, is of course actuated in the same manner as the form previously described. When it is desired to place the wire in engagement with the clip, it is merely necessary to insert the same through the opening 24 and flex the arm 25, by pullin u on the fin er clip 2-6, and slipping t e fi'ee end of t e wire under the arm 25. The arm 25, of course,

will urge the wire into intimate contact with the base plate or strip 20 and absolutely preclude the ossibility of the wire being accidentally withdrawn from the clip. The arm 25 will be drawn inwardly when tension is exerted on a wire which may be associated with a clip, thus forcing the wire into tighter contact with the base plate or strip 20.

From the foregoing description, it can be seen that an improved terminal. clip has been provided, for effectively holding electric wires against accidental displacement,

and which will permit the wire to be con- Ycniently and expeditiously placed into engagement therewith and movedout of engagcment therewith.
