INSULATOR.

SPECIFICATION forming part of Letters Patent No. 783,348, dated February 21, 1905.

Application filed March 18,1904. Serial No. 198,714.

To ail whmn it Wuty concern.-

Be it known that I, EvANs O. \VEIGHT, residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Insulators, of which the following is a specification.

My invention relates to the class of insulators which are so formed as to avoid the ne cessity of tie-wires to hold the main wire in position thereon, and it seeks to providea device of this character in which the wire will be tightly held and to which the wire may be rapidly secured and with a minimum amount of trouble.

Again my invention seeks to provide an insulator of this character which will be simple and durable in construction and which will readily serve its intended purposes.

With other objects in view, which will be hereinafter fully apparent, the invention consists in certain novel construction of insula tors, such as will be first described in detail, and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective view of my invention as applied for use in holding wires thereon in one direction. Fig. 2 is a similar view showing the wires wound on the insulator in a slightly different manner. Fig. 3 is a similar view showing the insulator used at the corner, the wires being wound substantially as shown in Fig. 2. Fig. l is a side elevation of the insulator. Fig. 5 is a front elevation thereof. Fig. 6 is a side elevation of the side opposite that shown in Fig. 4. Fig. 7 is a horizontal section on the line 7 7 of Fig. 4:. Fig. 8 is a rear elevation of the insulator.

.In the drawings, in which like characters of reference indicate like partsin all the figures, 1 designates the insulator, which has an axial bore 1 to receive the securing-screw 2 to hold the same in position. (See Fig. 1.) Near the upper face 1 the insulator has a transverse horizontal bore 1, which is located in the rear of the vertical bore 1, through which the line-wire w passes.

3 designates a groove extending from the end 10 of the bore .1 on one side face, passing downward toward the front part of the insulator and then across the front of the insulator, as at 3, to the opposite side. The groove portion 3 then extends upward, as at 3", and merges with a groove portion 3 across the top face 1, the groove 3 merging with a second side groove 3, extending from the rear to the front of the insulator and which also merges with the groove 3 and bore 1 at their juncture. By forming the insulator with the grooves 3, 3, 3, and 3 a knob 1 will be provided, as shown.

In the practical application of my invention the wire on is passed through the bore 1" from right to left and then brought down into the groove 8, up in the groove 3 and across in the groove 3, from which when the wire is to continue in the same direction it is passed onward, as shown in Fig. 1. Again the wire may be arranged substantially as shown in Fig. 2, where the wire is threaded from right to left through the bore 1 and then passes into the grooves 23 3 '3 respectively, and from thence onward in the same linear direction. It should be understood to extend the wires at right angles it is only necessary to turn the wire in the manner indicated in full lines in Fig. 3 or as shown in dotted lines in Fig. 1.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that 1 provide a very simple in sulator capable of receiving the wire in several different positions and which is so constructed that when the wire is wound thereon the same will be tightly held from movement by its own tension and without the use of binder-wires.

In practice my improved insulator may be constructed of glass, porcelain, or any other suitable substance.

From the foregoing it is thought the complete construction, operation, and advantages of my invention will be readily apparent to those skilled in the art to which it appertains, and I desire it understood that slight changes in the detail construction of my improvement may be made without departing from the scope of the invention and the appended claims.

Having thus described my invention, what I claim, and desire to obtain by Letters Patent, is

1. An insulator having a longitudinal bore, and a transverse bore at one side of the longitudinal bore, said insulator having a groove commencing at one side of the transverse bore and extending downwardly and around to the front of the insulator, then upwardly toward the top of the insulator, then transversely toward the other side of the insulator, then downwardly and rearwardly and intersecting the transverse bore at the commencement of said groove substantially as shown and described.

2. An insulator consisting of a cylindrical body having a longitudinal axial bore 1 running its entire length and a transverse bore 1 disposed to the rear of the axial bore, said insulator having a surface groove commencing at one extremity of the transverse bore and passing downwardly as at 3 and around to the opposite side of the insulator as at 3, then upwardly toward the top as at 3" and then transversely across the top of the insulator as at 3, then downwardly and rearwardly as at 3 and merging with the transverse here at the point where the groove commenced, said groove forming a knob 4: and adapted to receive the line-wire substantially as shown and described.

3. An insulatorconsisting of a cylindrical body having a longitudinal axial bore 1 running its entire length and a transverse bore 1 disposed to the rear of the axial bore, said insulator having a surface groove commencing at one extremity of the transverse bore and
