TELEPHONE CLIP AND HANDLE.

Application filed March '5, 1919. Serial No. 280,820.

To all whom it may concern: Be it known that I, HAZEL B. BUsH, a citizen of the United States, residing at Redlands, in the county of San Bernardino and State of California, have invented a certain new and useful Improvement in Telephone Clips and Handles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to improvements in clips for attaching the-terminal wires of a portable telephone set temporarily to the branches of a-telephone line; and has to do also with a safety handle for applying the clips to the line. a

In order to betterunderstand the purpose of the invention I may relate briefly circumstances under which devices of this sort are used. I

Electrical power and light companies usually have telephone lines strung beneath their high voltage power lines, the latter carrying approximately 30,000 volts in some instances. I In case of anaccident with the highpower lines, it is thecustom to sendout trouble men fromadjoining stations between which the accident is known to have occurred to locate the difiiculty, and it is their duty, as they advance toward each other from their home stations, to telephone into the stations at intervals and report the conditions which they'find until the trouble is finally located. The very nature of the accident often charges the telephone lines with the voltage of the power lines and makes the application of the trouble-mans portable telephone set exceedingly dan-;

gerous.

The general objects ofmy invention are the provision of clips constituting theterminals of a portable telephone setv which,

bv means of an easily manipulated, in-

' sulated handle, may be'safely and convcniently applied to the branches of the tele phone line and which will hold vigorously against'dislodgment from any cause other than a peculiar'motion given them. preferably; by a pull upon thewiresof the port-.:

-' and its ends extend. upward and bear against a'ble telephone set, the clips being of such nature as to respond readilv to such a mo--- tion or pull, thereby to release themselves from the line: and'in' this connection,- it 18- a further object-of the invention-to provide a fitting that isipivotally;:connectedto each with each other. I aws are grooved transversely,' as indicated clip and rigidly attached, with efficient electrical contact, to the end of each,wire of a portable telephone set and through which proper electrical connection is constantly maintained between the wire and clip.

Furtherobjects are to provide a handle of the character above referred to .incorporating self-adjusting pivoted'jawspreferably two pairs, so. that the handle may accommodate both clips of a-set-and between which, clips OfVELIlOllSSlZES may be grasped at ditlerent angles and securely locked; andfto provide a handle of this.

nature that may be conveniently manipulated to open and close the. jaws at will from different positions .along the handle.

To these ends my invention consists in the combinations of elements set outin'the claims. annexed hereto and illustrated in the drawings accompanyingand forming a' part hereof and wherein Fig. 1 IS a perspective View of my improved clips attached to the wires of a portable telephone set, and applied to opposedbranches of a telephone line, the view including-the safety handle for applying the. clips to the line; Fig. 2

is a top view ofone of the clips applied to a line; Fig. 3 is a side elevation of the same; Fig. 4: is a sectional, view on line 44 of Fig. 3; Fig. 5 is an enlarged 'sect1onalde-= tail on'the-correspondingly numbered line of Fig. 3; Fig. 6 shows,-in perspective,l.the elements of the clip in separated condition: and Figs. 7 and 8 are elevational views at right angles to each otherv ofthe upper end of the handle. v

flfand 2 represent the opposed a telephoneline to which the terminals 3 of a portable telephone set (not. shown) are connected by means of my improved clips5.

Each clip consists of jaws 6 and 7, the former incorporating. a loop 'or bail 8 bepivoted upon ,a pin 10 which extends through aligning apertures in the ears and the web portions of the jaws 6 and 7' and tend to force them into clamping contact The inner faces'of the a 14: and bes shown in lii'g. 16,. and; .the

branches of tween which the ears 9' of the latterarej grooves gradually diminish in depth and width from one side toward the other of the jaws. This effect is really the result 01' the opposed surfaces of the jaws diverging gradually from the side of the clip where the grooves are deeper to the side where they are shallower, as will be readily seen from an inspection of Fig. 2. At the deeper ends of the grooves there are abrupt shoulders 15 which form, the top walls and which engage the telephone line in such manner as to vigorously resist removal of the clip from the line by a direct or straight pull on the loop or bail 8. The very gradual inclination of the jaws above the grooves 14- permits the clip to be readily attached to a line by the application of a moderate degree of force, the jaws being spread apart by the line as they are forced over the same.

It will be observed that the terminal wires 3 of the portable telephone set are pivotally attached, through fittings 16, to ears 17 that extend from the sides of the clip adjacent the shallow ends of grooves 1 1. Consequently, by a pull upon the wires 3, a sort of rotary or turning motion is imparted to the clips in the planes of the supporting lines, and inasmuch as only a very slight overhang of the shoulders 15 occurs on the sides of the clips to which the pull is applied, the clips readily yield and dislodge themselves. In this turning or rotating action, the clips swing about a point on the telephone line inward from their edges adjacent the deeper ends of the grooves, it being observed, especially in Fig. 1, that the opposed walls of the grooves converge gradually below the shoulders 15 so that no appreciable resistance is offered to the elevation of the sides of the clips adjacent the deeper ends of the grooves, as the opposite sides of the clips descend in response to the pull. This turning motion completely removes the shoulders 15 from linear engagement with the line, leaving only a frictional engagement between the clip and line. and

' the only force now tending to hold the pivoted thereto by means of a bolt 21.

clip to the line is the action of spring 12. Consequently, it is a very easy matter to withdraw the clips from the branches of the line by a comparatively slight pull on the wires of the telephone set.

The fitting 16 through which each wire of the portable telephone set is secured to its respective clip is preferably formed of sheet metal having a flat web portion 20 that bears against the ear 17 of the clip and is A nut 22 is shown as applied to the end of the bolt and is spaced from the web 20 of the fitting, and a spring 23 is confined between said web and a washer 24 that is backed by the nut 22 and constitutes a stop for the spring. This provides an easy-acting pivotal connection between the fitting 16 and jaws.

the ear of the clip and one which insures positive electrical connection between the two parts. The web portion 20 is surrounded by a flange 25 which merges at the free end of the fitting into a split sleeve 26 through which the end of the wire 3 of the portable telephone set is inserted. Inwardly of the sleeve, the exposed portion 27 of the wire is connected to a binding post 28 that is carried by the fitting. This permits the wires 3 to turn readily with respect to the clip, as in the operation of removing the clips from the telephone line, yet it avoids any abrupt bending of, the wires where they have connection with the clip.

The safety handle, hereinbefore referred to and by means of which the clips are applied to the branches of the telephone line, comprises a staff 30 within the upper end of which is rigidly supported an element 31 having, in its opposite edges, recesses 32 that are opposed to recesses 33 of jaws 34;, pivoted at 35 on opposite sides of the stafi 30. The element 31 is shown as having opposed pairs of ears 36 between which the jaws 34 are pivoted. The lower ends of the aws are branchd at 37, and guide blocks 38 are swiveled between the branches of the These blocks have bores within which pins 39 are guided, the ends of the pins 0pposite the blocks being pivotally connected at 4 0 to the upper ends of slides 41 and are applied to the opposite sides of the staff 30 and extend substantially throughout the length thereof, the slides being held to the staff by means of loops 4:2. The slides have lugs 13 that may be engaged by the thumb or finger of the operator to assist him in manipulating the slides. comparatively strong springs 45 are compressed between the blocks 38 and the upper ends of the slides; and it will be noted that small pins 47 are passed through the ends of the former pins 39 to prevent their withdrawal from blocks 38. I I

In the operation of the handle. the user grasps the same at any convenient position along the staff 30 and places the loops or bails 8 of the clips between the jaws 34 and the opposed portions of element 31 and pushes upward on the slides 41. The initial movement of the slides throws the upper ends of the jaws into contact with the loops or bails of the clips, and further movement results in a compression of springs 45 until. their inner ends pass over center, so to speak. As the slides continue to move upward they permit a slight relaxation of the springs until the upper ends of the slides engage stops 4:9. The springs now tend to hold the slides against displacement, and the jaws 34 in firm biting engagement with the bails of the clips. Because of the yielding connection between the jaws and slides afforded by springs e5, clips having bails of different dimensions may be grasped by the same handle. It will be observed, also, that the clips may be engaged with the handle at various positions about their bails thus permitting the operator to hold the clips in a position best adapted to the circumstances under which he is working. Also, by reason of the shape and serrated character of the clip engaging portions of the jaws 34: and element 31, the clips may be held firmly in any position in a plane at right angles to the 2. A clip plane of the former adjustment. Thus a universal adjustment is provided between the handle and the clips.
