STOP FOR WIEE'INSULATORS.

Specification of Letters Patent.

Patented Got. 10, 1916.

Application filed September 14, 1915. Serial No. 50,584.

To all whom it may concern:

Be it known that I, Mannicn 3V. i /hxn- SHALL, a citizen of the United States, and a. resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Stop for Wire- Insulators, of which the following is a full, clear, and exact description.

My invention relates to stops for wire insulators adapted to maintain a tubular insulator at predetermined points on a contluctor.

An object of the invention is to provide a simple and inexpensive stop adapted to hold an insulating tube at desired points on an electric wire. As, for example, where wires cross or pass other obstructions, and

which stops are detachable and will not injure the insulation of the wire.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in both views.

Figure l is an elevation of an insulated wire proi'ided with embodiments of my invention; and Fig. 2 is a plan view of a stop.

The stop consists of a washer 3 of fiber or any other insulating material, the central opening 4: of which Varies in accordance with the size of the insulated wire for which the stop is to be used; and the size of the washer 3 in general will vary in accordance with the size of the insulating tubes it is to retain on the insulated Wire. The Washer 3 ha's a sectorial cut-out 5, the narrower width of which cut-out is less than the diameterof the central opening 4, as clearly seen from Fig.

lVhen an insulating tube 6 is to be placed on an insulated wire 7 and the position of the tube is determined on the wire, a washer 3 is forced on to the insulated wire 7 at each end of the insulating tube 6. The central opening "Tl being of a lesser diameter than the insulating wire 7, the washer will grip the wire and, therefore, thetube, 6 is prevented from slipping on the wire-and maintained in its proper position on the insuiating wire 7. It will be seen that the washer 3 will in no way injure the insulation of the electric conduit.

I claim:

In combination with a wire having a yielding, insulating coating, an insulated tube on the coated wire and an insulated stop, for arresting the longitudinal movement of the tube on the wire, in the shape of a washer having Ia sectorial cut-out through which the washer is made to engage with the coated wire, the smallest width of the cut-out being less than the width of the Washer opening, and said opening of the washer being of lesser diameter than the yielding insulating coating of the wire to be engaged by the stop so that the said washer will pinch on the coating.

In testimony whereof I have signed my name in this specification in the presence of two subscribing witnesses.

MAURICE WILCQX MARSHALL.
