INSULA'OR.

Application filed May S, 1917.

To all 107mm t 'may concern:

Be it knownthat I, CHARLES Dlsnnnn'r, a citizen of the United States, residing at Logan, in the county of Hocking and State of Chio, have invented certain useful lmprovements in lnsulators, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to an insulator, and more particularly to the class of wire retaining devices for insulators.

The primary object of the invention is the provision of a device of this character wherein'an electric current wire can be securely fastened in the insulator and said wire can be readily removed when the occasion requires, the device being adaptable for use with various styles of insulators employed on cross arms or brackets for eX- terior electric wiring or on insulator knobs or cleats for interior construction of electric wiring.

Another object of the invention is the provision of a wire retaining device wherein the lemployment of nails, screws or other like fasteners is eliminated and the wire can be securely clamped in the insulator for holding said wire in place and is designed for use in supporting telephone or telegraph wires for the distribution of electric current.

A further object of the invention is the provision of a wire retaining device of this character which is simple in construction, thoroughly reliable and eliicient in use, strong, durable, and inexpensive of manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be' exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawing:

Figure 1 is a vertical sectional view of an insulator, showing the wire retaining device in side elevation constructed in accordance with the invention applied:

Fig. 2 is a top plan view thereof;

Fig. 3 is a side elevation of the retaining cylinder' of the device Fig. l is a perspective view of said retaining cylinder;

Fig. 5 is a side elevation of the bushing for the retaining cylinder supporting block.

Specification of Letters Patent.

Serial No. 16T/,249.

Similar reference characters indicate corresponding parte` throughout the several views of the drawing.

Referring to the drawing in detail, designates generally an insulator body which is formed with a circular socket or recess 10 opening through the top thereof, while formed in the insulator body A at diametrically opposite points in the wall of the recess 10 therein are wire receiving groove-s 1l in which is adapted to be engaged an electric wire or wires, while mounted within the recess 10 is the wire retaining device hereinafter fully described.

The wire retaining device comprises a block 12 preferably nade from porcelain, although the saine may bc made from any othel suitable insulating material and is formed in sections, the block being retained in the recess through the `medium of a securing bolt 13 which engages in the insulator body A as shown in Fig. 1 of the drawing,

rlhe block 12 is preferably of rectangular shape and is former with a wire receiving groove le which opens through the top of said block, and this groove is of curvilinear shape, with a flared or enlarged outer open end, the grooves 11 in the insulator body being correspondingly shaped to the groove l-l in the block 12, and the electric wires are adapted to be engaged in said grooves and retained therein in a manner presently described.

Formed medially of the block 12 is a seat 15 for receiving a rotary wire retaining cylinder 16 which, at the periphery thereof and centrally7 of the saine, is formed. with a rib 17 which engages in a channel 18 formed in the block 12, and this rib 17 engaging in said channel prevents lateral play of the cylinder 1G when rotated within the block. The cylinder 1G at one side is formed with a. longitudinally disposed notch 19 which opens through opposite ends of the cylinder and through the periphery thereof, the

'notch 19 being designed to receive the electric winJ or wires therein, and on the rotation of the cylinder 16 in one direction the said wires will be brought into a posit-ion at the closed end of the grooves 11 and 11i in the insulator body A and block 12 therein for the retaining of the wire andthe fastening of the same in the insulator.

Mounted within the channel 18 is a bushing 2O which receives the ribs 17 and prevents any st-rain upon the block 12, thereby avoiding` the racturing of the block in the working of' the wire retaining device.

ln the c ylinder 16 diametrically opposite the notch 19 is notch 21 which is longii dinally disposed and opens through the op posit-e ends and periphery ot said cylinder, and spanning this notch are normally outwardly bowed expanding webs 23 which, on the application of a tool such as pliers thereto, and the bending of the same in parallel relation to each other, will distort the cylinder to bind the same within the seat l5 therefor in the block 12 so as to prevent the working ol the cylinder 16 outwardly from said seat.

Forni-:fd on and projecting laterally 'lfrom opposite sides ot' the cylinder 1G atV the 3eri'lgiliery thereof are arms 23 formed with ri ght angular legs or levers 21twhich are disposed beyond opposite sides of the block 12, while :formed on opposite side faces of he latter are cam swells 25 with which engage legs or levers Qd when the cylinder 1G has been rotated in one'direction for the bringing of the electric, wires to the inner ends of the grooves 11 and lll, and in this manner the cylinder is held fast in position for retaining the wires in said grooves. Thus it will be seen that the electric wires are retained within the insulator A and held tast by the retaining cylinder 1G which is locked in its retaining position when the legs or levers let on the arms Q3 ride on to the swells Q5 at opposite sides ot the block 1Q- within the insulator.

lt is of course to be understood that thc wire retaining` de Tice can be mounted on or in various styles of insulators and ditferent sizes ot' electric wires can be retained thereby for the fastening of the same in place. On reversing the rotation of the retaining cylinder 16 the wires can be readily removed or detached from the insulator, as will be obvious.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the herein. described insulator will be readily apparent and, therefore, a more extended explanation has been omitted.

Having thus described my invention, I claim:

1. A Wire retaining device comprising a member' having a wire receiving groove therein, a wire retaining cylinder rotatably mounted within said member and having a notch for receiving a wire for delivering the same to the inner end ol2 the wire receiving groove in the member on the rotation of said cylinder in one direction, and means on the cylinder and member for locking said cylinder against accidental rotation in the reverse direction.

wire retaining device comprising a having a wire receiving groove therein, a wire retaining cylinder rotatably mounted within said member and having a notch for receiving a wire for delivering the same to the inner end of the wire receiving groove in the member on the rotation ot said cylinder in one direction, means on the' cylinder and member for locking said cylinder against accidental rotation in the reverse direction, and a guide rib on the cylinder and engaged in the member.
