TREE AND WIRE PROTECTOR Filed Feb. 10, 1931 INVENTOR ATTORNEY Patented Feb. 7, 1933 UNITED STATES PATENT OFFICE TREE AND WIRE PROTECTOR Application filed February 10, 1931.

This invention relates to improvements in protectors and has for the primary ob ect, the provision of a device of the above stated character which may be easily and quickly applied to an electrical conductor for preventing the latter from coming in contact with the limbs of trees, other conductors or any object which may be in the path of the respective conductor and which would form an electrical ground thereto.

Another object of this invention is the provision of a casing of non-conductive maternal and provided with means whereby the casing may have conductors of different sizes secured therein either when insulated or noninsulated and which will assure complete protection to objects which may be adjacent to the conductor and is especially adaptable for use on electrical conductors that pass through trees when the limbs thereof may strike the conductors due to a swaying of the tree in the wind and which in a very short time chafes the insulation of the conductors to an extent that the conductors are grounded, creating short circuits and injury to the tree by flames created by the short circuits.

A further object of this invention is the provision of a protector of the above stated character which will be simple, durable and eflicient and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, as will become more apparent as the description proceeds, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view illustrating a protector constructed in accordance with my invention,

Figure 2 is a side elevation partly in section illustrating the same.

Figure 3 is a transverse sectional View illustrating means of mounting the conductor within the casing.

Serial No. 514,895.

Figure 4 is a diagrammatical view illustrating top and bottom sections of the casing.

Figure 5 is a perspective view illustrating one of the securing means for attaching the conductor to the casing.

Referring in detail to the drawing, the numeral 1 indicates a casing having each end fully opened for the purpose of permitting a conductor 2 to pass through the casing for the purpose of preventing the conductor Go from coming in contact with objects. The casing l is constructed of non-conductive material of light weight and containing sufficient rigidity to maintain the casing in preper shape and includes a pair of sections which are of substantially U-shape in cross section and have their sides arranged in overlapping relation as clearly shown in Figures 1 and 3.

Located within the casing 1 and adjacent each end are pairs of insulators 3 carrying screw-threaded studs 4 that extend through the top and bottom walls of the casing and also through substantially U-shaped clamps 5 and receive nuts 6 to retain the insulators within the casing and also retain the clamps 5 in position. The free ends of the clamps are oilset to provide attaching ears 7, some of which are apertured to receive bolts 8, while the others are slotted to receive the bolts 8 and the latter are retained in the slots by nuts 10 threaded on the bolts providing a construction which will permit the sections of the casing to be adjusted relative to each other and also permit the sections to be separated when applying the casing or removing it from the conductor 2.

Each insulator 3 has its inner end cut in substantial V-shape as shown at 11 and serrated to receive the conductor. The insulator is cut away to form inclined faces 12 disposed on opposite sides of the V-shaped portion 11 to permit the overlapping of a pair of insulators when assembled and provides a construction wherein the insulators may be adjusted relative to each other for the urpose of accommodating conductors of ifi'erent sizes. By reference to Figure 5 it will be seen that one leg portion of the V-shaped cut .out portion is disposed laterally of the other leg portion providing a comparatively wide bearing plogltion 13 at the apex for the conductor. s arrangement is formed by theinclined faces 12.

From the foreioing description taken in connection with t e accompanying drawing, it will be seen that avery efiicient rotector has been provided and when app ied to a conductor, the latter will be prevented from 1 contactin with other objects and also it will be noted t at the protector can be easily and quickly applied to any point desiredon the conductor and that the device can be adjusted or rendered adaptable to conductors 15 of difierent sizes, the adjustment of the protector being made through the bolts 8 which secure the clamps together;

ile I have shown and described the preferred embodiment ofmy invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope as claimed.

Having thus described my invention, what 1 claim is:

A protector comprising a casing to be positioned about a conductor and including a pair of overlapped sections, means adjustably and detachably connecting the sections of the casing, insulators arranged in opposite 1y disposed pairs secured to said casing and having their opposing ends cut in V-shaped formation to receive the conductor and cut away at opposite sides of the V-shaped ortions to rovide inclined faces adapted to permit t e insulators to have overlapped relation with each other and thereby permit the insulators to accommodate conductors of difi'erent sizes.

40 In testimony whereof I a my signature.

JOHN LESTER SMITH.
