Specification of Letters Patent. Patented Dec, 30, 1913,

Application filed February 19, 1912. Serial No. 678,668.

To all whom it may concern Be it known that. we, DONALD MAoCoLL and DE LANGEY A. CAMERON, citizens of the United States, and residents, respectively, of Montclair, in the county of Essex and State of New Jersey, and Geneseo, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Nails, of which the following is a specification.

This invention relates to nails adapted particularly for use in connection with plaster-board, or similar sheet-material, used in the construction of buildings.

The object of the invention is to produce a nail which may be cheaply manufactured of wire by ordinary bending operations, this nail having, in addition to the usual shank or driving-portion, a loop at one end of the shank and ahead or abutment at an intermediate point, the head or abutment being adapted to secure the plaster-board in place, while the loop is adapted to operate as an anchorage for a coating of plaster or roughcast applied to the surface of the plasterboard.

To the foregoing end we employ a construction in which the shank, the loop and the head or abutment of the nail are all formed of a single continuous piece of wire, the wire being bent back upon itself to form both the loop and the intermediate head or abutment, in the manner hereinafter described and claimed.

In the accompanying drawings :-Figure 1 is a perspective view of a nail embodying the present invention; and Fig. 2 is a sectional view, showing the manner in which the nail is used.

As shown in the drawings, the nail is formed of a single piece of wire having a straight portion 8 which constitutes the shank or driving-portion of the nail, and which is pointed, or otherwise adapted. at one end 4, for convenience in driving the nail into wood or other material. I

The loop-portion 5 of the nail has one .extremity 6 continuous with the shank 3, while the other extremity 7 of the loop is continuous with a portion 8 which is coiled back upon the shank. The terminal coil constitutes a head or abutment at an intermediate point on the shank, and also strengthens and supports the loop-portion. This nail may be entirely, formed by an automatic wire-bending machine of ordinary form, since its construction involves nothing but bending operations, except for the pointing of the end 4, which latter operation may be performed in any well-known manner.

In using the nail, as shown in Fig. 2, the shank is passed through the plasterboard 9, or similar material, preferably through a perforation provided for this purpose in the board, and is then driven into the stud or ground 10 to which the board is to be affixed. The head or abutment 8 then tersunk at the outside to receive the head or abutment, but it will be understood that it may be used withoutthis arrangement, the portion of the nail between the head and'the loop being, in the latter case, of less length than in the case of the illustrated nail. The loop is preferably arranged to lie in a plane substantially normal to the shank of the nail, thus permitting the use of a large loop in a comparatively thin layer of coating material. This arrangement also permits the nail to be driven with a hammer in the usual manner, the impact of the hammer beingreceived directly in'line with the shank by the extremities 6 and 7 of the loop.

We claim 1. A nail comprising astraight shank, a loop, at the end of the shank, lying in a plane substantially normal to the shank, and an abutment, at an intermediate point on the shank, adapted to arrest the shank with the loop, at a-predetermined distance from, and substanitally parallel with, a surface throughwhich the nail is driven.
