Specification of Letters Patent.
Patented Dec. 11, 1917.
Application filed August 10, 1915. Serial No. 44,725.
To all whom it may concern Be it known that we, HARRY A. PHARO, a citizen of the United States, and a resident of lVilkinsburg, in the county of Allegheny and State of Pennsylvania, and l/VILLIAM SCHAAKE, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Insulators, of which the following is a specification.
Our invention relates to insulators adapted to support electric conductors and cables, and it has special reference to insulators that are adapted to support conductors at points where the conductors are led around corners and where it is now customary to attach the conductors to the insulators by means of tie wires twisted around the conductors adjacent to the insulators.
The'object of our invention is to provide an insulator of the above indicated character which shall embody means for supporting conductors securely without the use of tie wires or other external fastening means and in which the supporting member may be readily adjusted to any angular position with reference to the bodymember of the insulator.
In the accompanying drawing, Figure 1 is a plan view of an insulator constructed in accordance with our invention, and Fig. 2 is a vertical sectional view of the device shown in Fig. 1, the section being taken substantially along the line II-II, Fig. 1.
The insulator shown in the drawing consists of a body member 1, preferably of molded insulating material and preferably surrounded by a metallic jacket 2. A screwthreaded central opening 3 is provided within the body member 1 for. attachment to the usual supporting pin, and an annular, external depression or groove 4:15 provided about midway between the ends of the insulator.
Adjacent to the groove 1 and near the lower edge of the insulator, is an outwardly extending fiat flange 5 which may be formed integral with the jacket 2, as shown, or may be formed separately and attached to the insulator in any convenient manner. The flange 5 serves to support a movable ring or collar 6 which surrounds the body portion 1 and is provided with an outwardly and upwardly extending curved finger 7. The
curvatures of the finger 7 and of the annular depression 4 are such that they cooperate to receive a conductor, the transverse outline of which is indicated in dotted lines at 8 in Fig. 2. The finger 7 may be strengthened, as shown, by means of a downwardly-extending projection 9.
At a point removed from the finger 7 the collar or ring 6 is provided with an enlargement 10 which is perforated to receive a short bolt 11.- The head 12 of the bolt 11 extends beneath the flange 5 and cooperates therewith to clamp the collar 6 rigidly in any angular position which may be selected,
the bolt being provided with a nut 13 which may be loosened to permit angular adjustment of the collar 6 and then tightened to maintain the collar in its adjusted osition.
When an insulator constructed in the manner shown is used for supporting a conductor at a corner, the insulator is first tightly screwed on the pin and the collar 6 is then so adjusted as to bring the finger 7 to the side ofthe insulator which is engaged by the portion of the conductor that is bent around it. When the conductor is placed in position, it is held in the depression 4 of the body member by the finger 7 and cannot I departing from the scope of our invention.
For example, the body member of the insulator need not be made of molded material and the holding finger 7 may extend outwardly to a greater or less extent, as special circumstances may require. It as to be understood that our invention comprlses these modifications and all others which fall within the scope of the appended clalms.
We claim as our invention:
1. An insulating support comprising a body member provlded with a laterally proj ecting annular flange, an outwardly and upwardly extending finger ad ustably supported upon said flange, and means for clamping the said finger to the said flange in any position to which it may be ad usted.
2.

3. An insulating support comprising a body member having a laterally projecting metallic flange, an annular metallic member adjustably clamped tothe said flange and surrounding the said body member, and an outwardly and upwardly extending supporting finger carried by the said annular a. An insulating support comprising a body member having a laterally projecting annular flange adjacent to its lower end, an outwardly and upwardly extending supporting finger carried by the said flange and circumferentially adjustable thereon, and means for clamping the said finger to the flange in any position to which it may be adjusted.
5. An insulating support comprising a body member having a laterally projecting flange, a circumferentially adjustable annular member resting upon the said flange and having an outwardly and upwardly extending supporting finger, and means for clamping said annular member to said flange in any position to which it may be adjusted.
6. An insulating support comprising a body member having a laterally projecting flange, an annular member adjustably supported upon said flange and provided with a single outwardlyand upwardly extending integral finger to coiiperate with the said body member to form a conductor-retaining support, and means for clamping said ger in any adjusted position.
7. An insulating support comprising a body member of insulating material pro .vided with an external casing having a laterally projecting annular flange near its lower end, a circumferentially adjustable ring resting upon'the said flange and provided with an outwardly and upwardly extending supporting finger, and means for clamping the said ring to the said flange in any position to which it may be adjusted.
8. An insulating support comprising a body of insulating material, an external casing for the said body provided with an outwardly extending annular flange, a circumferentially adjustable member resting on the said flange and provided with an outwardly and upwardly extending supporting finger,
naaaeao and clamping means for securing the said member to the said flange at any desired single point.
9. An insulating support comprising a body of insulating material, an exterior casing for the said body having a laterally probe adjusted.
11. An insulating support comprising a I body member of insulating material provided with an external casing having a laterally projecting annular flange adjacent to its lower end and an annular groove adj acent to the said flange, a circumferentially adjustable ring resting upon the said flange and provided with an outwardly-extending supporting finger, and means for clamping the said ring to the said flange in any posi tion to which it may be adjusted.
12. An insulating support comprising a body member provided with an annular groove and with an annular flange adjacent to the bottom edge of said groove, a circumferentially adjustable ring resting upon the said flange and provided with an outwardly-extending supporting finger, and means for clamping the said ring to the said flange in any position to which it may be adjusted.
13. An insulating support comprising a body of insulating material provided with an exterior casing having an annular flange near its lower end, a circumferentially adjustable ring resting upon the said flange and provided with an outwardly-extending supportin -finger, and means for clamping the said rlng to the said flange in any position to which it may be adjusted.
In testimony whereof we have hereunto subscribed our names this 28th day of July, 1915.
