SPECIFICATION forming part of Letters Patent No. 427,296, dated May 6, 1890

Application filed December 31, 1889. Serial No. 335,497  (No model.)

To all whom it may concern:


Be it known that I, JOSEPH F. BUZBY, a citizen of the United States; residing at Royer's Ford, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful improvements in Glass or other Insulators for Use with the Wires on Telephone or Telegraph Poles; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to insulators for use with the wires on telegraph or telephone poles; and it consists in the improvement hereinafter described, and pointed out in the claim.

Figure 1 of the drawings is a side elevation showing my insulator with tie wire therein; Fig 2, a detail perspective view of the insulator, and Fig. 3 a similar view of the insulator-Stand.

In the drawings, A represents a telephone or telegraph wire secured by an end hook a in the staple B of a standard C. The latter has a square tenon c which fits a corresponding hole in the base-board D.

E represents my insulator, which has the central tapering vertical bole e in its lower end to fit over an upwardly-tapering projection f on the insulator-stand F and a flange e, which bears on a corresponding flange f' of the stand, the two flanges being clamped together by a spring-latch G, made fast on the side of the stand.

The insulator is provided with the perpendicular slot e in which the wire rests, and an


open communicating slot e3 arranged at an oblique angle to slot e2, so that one end of slot e3 opens into the upper end of slot e2 while the other end of slot e3 opens into the lower end of slot e2.

In order to put the insulator on the wire; it is turned out of a perpendicular until the slot e3 is in the same plane with the wire, which is then readily entered. The insulator is then turned back to a perpendicular and so locked to its stand. The head g of the spring-catch projects over the flange f of the stand, and, being inclined at g', yields to the insulator, flange e' as the latter is pressed down, and then overlaps it, so as to hold the insulator E securely to its stand F. In the position shown in Fig. 1 of the drawings the wire A lies across the slot e3 and therefore cannot possibly escape.

The shank f3 of the insulator-stand is made to fit a hole in the base-board, to pass there-through, and to have its flange f' supported on the base-board.

Having thus described all that is necessary to a full understanding of my invention, what I claim as new and desire to protect by Letters Patent, is---

An insulator having the hole e in its lower end and the flange e in combination with a stand F, having the projection f flange f', and spring-catch substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses:
