INSULA'IOR.

Application filed April 6, 1921. Serial No. 458,941.

To all whom it may concern:

Be it known that I, JAMES LEsLIE WILSON, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented a new and Improved Insulator, of which the following is a full, clear, and exact description.

This invention relates 'to electrical supporting insulators for current-carrying wlres. An object of the invention is to provide an insulator to which the-wires or devices to be su ported can be very quickly, simply and e ciently attached without the wire or su ported device coming in contact with metal or conducting material on the insulator.

Another object resides in the provision of means whereby in its assage through the insulator the wire or evice can swing or have a curved passage without being subject to wear or friction.

A further ob'ect resides in the provision of means whereby the wire is held firmly in place by a cover portion which can bevery quickly and easily applied to and removed from the body portion of the insulator.

A still further object resides in the particular construction and arrangement of parts which are hereinafter described ind claimed and shown in the accompanying "drawin s.

The lIlVBIltlOll is illustrated in the draw ings, of whichigure 1 is a view of the insulator with the central portion in sections;

Figure 2. is a side elevation thereof;

Figure 3 is a top plan view of the body portion of the insulator with the wire'or conductor shown in place; and

Figure 4 is an inverted plan view of the cover portion of the insulator.

The preferred embodiment of my invention, as shown in the drawings, comprises an insulator'having a body ortion 1 and a cover or top portion 2 whic is adapted to be applied to the body portion 1. The cover and body portions are adapted to meet in a' flat contacting surface suc as 3. On the upper surface of the body portion 1 are provided a pair of spaced cpro ecting ribs 4 and 5 which project upwar ly from the surface of the body portion 1 and extend across this surface between Opposite edges. The

outer edges 6 of the ribs are straight, whereasthe inner adjacent edges 7 are symmetrically curved as shown in Fig. 3. These ribs form between them a recess in which a wire or conductor such as 8 is adapted to lie. By having the adjacent edges or surfaces 9 curved, it will be observed that the wire 8 can swing in the recess formed between the ribs 4 and 5 or pass therethrough in acurved manner without meeting any sharp edges, wear or friction. The lower surface or face of the cover portion 2 is provided with a recess 9 of a depth equal to the height of the ribs 4 and 5, and a width substantially equal to the width between the outer edges 6 of the ribs 4 and 5. This recess is provided with lateral walls 10 which are adapted to lie closely adjacent of the ribs when the cover is placed on top of the body portion 1.

In a line at right angles to the line of extension of the recess 9, through the cover portion 2 and on opposite sides thereof, are disposed a pair of projecting lugs 11 to which suitable latch members 12 are piv-.

oted. These latch members 12 are made of wire bent over in the form shown to engage with lugs 11 and at the other end provided with an under-turned loop portion 13 which is adapted to engage under the lower edge of a shoulder 14 on the body portion. This shoulder 14 is in the form of an outwardly projecting flange portion extending circularly completely around the body portion.

In the application of the device, the cover portion is supposed to be removed from the body portion; whereu on the conductor or wire 8 is placed in posltion. The cover portion is then placed on the body portion with the recess 9 disposed over and embracing the ribs 4 and 5 and, therefore, confining the wire in the grooves between the ribs 4 and 5. The latch members 12 are can ht under the edges of the flange or shoul er 14, and b 1 reason of the resiliency of each wire latc member 12, the cover is held firmly on to the body portion.

What I claim is':

An insulator, comprisin a body havin at the upper end an annu ar shoulderan provided on its upper face with spaced ribs of a height a little greater than the diamwhereby it is not subjected to i the edges or surfaces 6 Y v a recess of A the ribs, said recess extending entirely eter of the wire te beheld therehetween,

a depth equal to the height of across the face of the cover and having amen-7e straight Walls ,outer edges of t pivoteqi to oppesite engaging; the shoulder? .the cdver on 1 ing close to the straight e ribs, and latch'members' sidespfthe cover and 1 i'he bedyi191 lock the body with their faces (iireetl'y incontact with each other.
