SPECIFICATION forming part of Letters Patent No. 701,246, dated May 27, 1902.

Application filed March 25, 1902. Serial No. 99,938. (No model.)

To ctZl whont it may concern:

Beit known that I, ELBERT T. BAILY, a citizen of the United States, residing at Mount Kisco, in the county of 'Westchester and State of New York, have invented certain new and useful Improvements in Insulator Pins and Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 5

My invention relates to an improvement in insulator-pins and is embodied in the construction and arrangement of parts presently to be described, and defined in the claims.

The invention relates more particularly to that class of devices-such as pins, brackets, or pegs-for supporting and carrying conductors, such as overhead conductors, and it is designed more particularly for use in connection with cross arms or poles or other supports; and the object of the invention is to provide a pin which can be quickly adjusted and applied, one wherein metal can ,be employed in its construction, a pin or carrier which will securely hold the insulator against accidental movement or escape, which can be cheaply manufactured, and'which in its application will avoid the necessity of boring or drilling the supporting member to which the same is attached.

Other objects and features of the invention will presently be stated.

In the accompanying drawings I have shown a preferred form and modification of the invention; but it is to be understood that the generalprinciple and nature of the invention can be applied in various ways and With various forms of construction other than those shown.

Figure 1 is an elevation of the cross-arm of a supporting-pole, showing the improved pin thereon. Fig. 2 is a side elevation of the same. Fig. 3 is a detailed section through the yielding supporting-arms of the pin. Figs. 4, 5, and (3 are modified forms of the construction shown in Fig. 1. Fig. 7 illustrates a modified form of the invention, the same being in the form of a bracket or attachment to the side of the support.

A designates a cross-arm of a supportingpost, which is constructed conveniently with a longitudinal channel B therein.

0 O designate two independent pin-sections arranged and fashioned so that when in proper relation they constitute the pin. These members 0 and O are conveniently constructed ofmetal, having the lowerangular portions 0 with upturned ends fitted in the groove B. The port-ions c are connected to the vertical portions 0, which are extended upward and bent inward obliquely and thence upward at an oblique angle, forming thereby spring or yielding extensions 0 The extensions c carry on their upper ends semicylindrical threaded insulating-blocks 0 the threads being on the outer face only, while the inner faces iit the sides of the extensions. To secure the blocks in place, recesses e are formed near their upper ends, into which the turned over ends e of the extensions fit. Other means may, however, be employed for that purpose. Between the extensions may be placed a wood or insulated filler-strip 0 (see Fig. 6,) which has a threaded edge corresponding with the threads of the blocks 0. D designates the insulator, of a well-known form and construction,screw-threaded on the threaded portions of the pin.

The construction above described is such that by embracing the sides of the arm A closely the upper ends of the pin will be separated andby securing the insulator thereonto the parts will be drawn close together, and owing to the yielding spring nature of the material of which the pin members or sec tions are constructed there will be a constant binding tendency between the insulator and the pin, thus serving to firmly hold the insu-.

lator in place. To add to the rigidity or strength of the upper portions of the pin,suitable braces o are formed along the outer faces of the oblique portions. These braces may be secured to the metal of the pins, but preferably are formed by rolling or striking up the metal of the pins between the edges, forming thereby crimps or strengthening bends. To adjust the pin on the arm A, it is only necessary to place the different members thereof in position and then clamp them in position by screwing on the insulator. It may, however, be found convenient in some cases to pass screws or nails, such as E, through the upright portions of the pin members into the arm A.

A modification of the construction above described is illustrated in Figs. 1-, 5, and (5. In the former the pin is constructed of a single band 0 spanning the bottom of the arm, as shown at E. In Fig. 5 the pin members are similar to those shown in Fig. 1, except the channel in the arm A is omitted and the struck up ends of the lower portions care in the form of brads or teeth, which penetrate the material of the arm. In Fig. (i I have shown a construction whereby the members of the pin are constructed without the lower angular portions, the bent-in ends taking into the longitudinal grooves h in the sides of the arm A. In this connection Ihave found itconvenient in some cases to substitute for the threaded wooden blocks of the pin metallic structures, as G, the same being formed of concavo-convexed extensions of the upper portions of the pin, their outer faces being threaded. An interposed wood filler C may be used. In Fig. 7 the invention is shown in the form of a bracket,wherein the two pin members II II are connected at their outer ends, as at It, from which point they diverge outwardly and terminating in securing portions 7L. On the sides of the pin are the insulating-blocks II 11*, conveniently of wood, the same being secured in position by having struck-up or otherwiseformed ledges 7L2 7L3 projecting from the sides of the different branches of the pin. By forcing the insulator onto the pin the diverging arms thereof are forced together and the spring effect of the construction shown in Fig. 1 is attained.

By the construction above described I am enabled to secure an insulator-pin to the support without puncturing or boring out the support, as is the case when a wooden pin is used. I also largely prevent the pin from becoming loose on the cross-arm.

The invention is also designed for application to various forms of arms or supports and can be of a shape to fit various angles. It is also apparent that in the art of manufacturing the pins can be made at a relatively small expense.

I desire to call particular attention to the arm having a channel in its under face, as I have found that such a construction enables the application of the pin, as above described, at any point on the arm and permits the application of the pin between two wires, its adjustmenttoward and from adjacent wires, and its removal without interfering with the adjacent wires. It is also apparent that an arm of less diameter than those now in use can be employed, thus doing away with a large amount of weight and superfluous timber.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
