WIRING-TACK.

Specification of Letters Patent. Patented Feb. 13, 1912. Application filed September 18,-1911. Serial No. 050,005.

To all whom it may concern:

Be it known that I, CHARLES C. BLAKE, residing at Brookline, in the county of Nor folk and State of Massachusetts, have invented certain Improvements in Wiring- Tacks, of which the following is a specification.

The present invention relates to means for supporting insulated wires in position on Wood surfaces or plastered walls, in such manner as to hold the same securely without marring or damaging the wood or plaster and also present an attractive appearance.

The invention consists of 'a wiring tack adapted to embrace the insulated conductors of a pair, and consists of a metal plate having an insulating lining and a nail or pin passing through the central part of the plate andlining, the parts being held together by frictional pressure or with a suitable cement, all of which I will now proceed to describe and point out in particular in the appended claims.

In the drawings which form a part of and illustrate the invention,Figure 1 is a per.- spective view of the insulated wiring staple; Figs. 2 and 3 are respectively top and side views of the metal plate; Figs. 4 and 5 are respectively a top and side view of the insulating lining; Fig. 6 is a section on line w, w of Fig. 5 looking in the direction of the arrow; Fig. 7 is a detached View of the nail or pin; Fig. 8 is a view to illustrate the application of the staple; and Fig. 9 is a sectional view illustrating a modification.

In the drawings, a is an oblong metal plate having its

ends

1, 1 bent at substantially right angles; the central portion of the top part is elevated to form a ringshaped projection 2, which has a central depression 3 whose edges are drawn out thin forming a tubular orifice. The plate is formed in dies and is thus very cheaply made. Within the plate a is an insulated lining I; ma e from a ribbon of fiber or other suitable material, while soft and easily worked in a mold, having its central portion folded or doubled over so that the sides touch or nearly so, as 5, then turned over to form the tops, 9, 9, and again to form the

sides

4, 4, and a pin forced between the sides,

centrally thereof to make a hole 7; at the nail or pin a is inserted into the depression 3 and pressed downward through the straight hole 7, the parts are held together; the head of the nail rests in the. depression 3 and is held by its lower edges and-also by the walls 6 of the central portion 5, of the lining b which steadies the same.

By reference to Fig. 8, inwhich is shown a wire tack securing the conductors C, C of a pair to a support S,-it will be seen that the lining b prevents any contactbetween the metal parts of the tack and the conductors. I may, if I choose, cause the plate and lining to adhere to each other. by means of interposed cement or sticky substance.

It is not strictly essential that the elevated portion 2 be formed on the upper face of the plate, although it gives stability to the same in driving the nail, and Fig.9 shows a crosssection of a device in which theelevation 2 is left off, in this case the depression 3 may ext-end farther inward to give support to the nail head.

The several parts may be kept in separate places and assembled when about to be used, but I prefer to assemble the parts and pack the completed tacks in boxes for sale.

I claim as my invention- 1. A wiring tack comprising a metal plate having its ends bent over and downward with. a central opening through the metal, a nailor pin having its head supported in said opening, and an insulating lining covering the interior surface of the plate the central portion of which is doubled, perforated. and extending downward. forming a midway partition and embracing the nail or pin, as set forth.

2. A wiring tack comprising'a metal plate having opposite ends bentat substantially right angles with a central depression in its upper portion extending through the metal forming a tubular orifice, a nail or pin supported by its upper end in said depression, and an insulating lining the central portion :of which is doubled and centrally perforated, its sides being parallel and embracing a central depression extending through the .metal, a nail or pin having its head supported in said depression, and an insulating linfits snugly inside the plate a,.'and when the I ing the central portion of which is doubled and perforated and embraces the nail or pin,:

as set forth.

4. A wiring tack comprising an oblong metal plate having. its ends bent 'overand downward, a portion of its upper'surface being elevated and having a centraldepression extending through the metal, a nail or pin supported by its upper end in said depression, .andan insulating lining'the central portion of which is doubled and perforated, its sides being parallel and embracing the nail on pin.

5. A'wirin tack comprising a metal plate right ang es, a portion of its upper surface having a ringshaped elevation with a central depression extending through the metal,

a nail or pin supported by its upper end in said depression, and an insulating lining the 20 name to this specification in the presence of 25' two subscribing witnesses, this fourteenth day of September 1911.
