No. 440,364. Patented Nov. 11, 1890.





SPECIFICATION forming part of Letters Patent No. 440,364, dated November 11, 1890.

Application filed December 6, 1889. $erialNo. 332,808. (No model.)

To all whom it may concern:

Be it known that we, JOHN B. PERRAUD and WILLIAM BEoHToLD, both residents of the city, county, and State of New York, have invented certain new and useful Improvements in Heads for Nails, Buttons, &c., of which the following is a specification.

The object of our invention is to connect a head for nails, buttons, &c., with the stud or shank by which the head is secured to a nail, board, fabric, or the like.

The invention consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a side view of a nail and its head connected together according to our invention. Fig.2 is a central longitudinal section enlarged on the plane of the line y y, Fig. 3.

Fig. 3 is a cross-section 011 the line a: :r, Fig.

2, showing the inner side of the nail or button-head having a perforated plate or washer attached. Fig. 4 is a detail face view of said plate or washer, showing part of the split stud passing through the plate; and Figs. 5, 6, 7, 8, 9, and 10 are detail views, hereinafter more fully specified.

Referring now to the accompanying drawings, the letter A indicates a head for nails, buttons, and like articles, and B indicates a nail, screw, or the like, to which the head A is to be attached.

D is a stud, screw, or shank to be secured to the head A.

E is a plate or washer placed on the inner side of the head A and secured thereto. The plate or washer E is provided with a series of holes a, and the head A is cast upon said plate or washer, so that the material of the head will pass through said holes, and thereby hold the plate to the head. Said plate or washer also has an aperture 1), through which the stud, shank, or screw D may pass,as shown. One end of the stud, shank, or screwD passes into the head A, and to secure it in place the head is cast around the stud. In order to more securely hold the stud, shank, or screw to the head A, one end of said stud is widened or forked, and the prongs d d bent outwardly, as shown,'so that the material of the head A will envelop said prongs d, whereby the stud, shank, or screw D is securely held to the head A. ith the above arrangement the head A may be made of cast glass, and the studor screw secured in it without danger of the parts becoming separated. By making the holes a in the plate or washer E, and casting part of the material of the head A through said holes, the plate or washer will not turn on the head A when a twisting strain is put upon the washer. The outer end of the stud or shank D (shown in Figs. 2 and 3) is split or forked, forming prongs f, which have an outward spring tendency, and when passed into an aperture or socket c in the nail B, or else where, will, by friction, hold the head A in place. The outer part of the socket c is Widened or made cone-shaped, so that when the nail is driven the metal at the end of the nail will not be swaged over to close the socket. By the above arrangement the nail may be driven in a wall or other place 9 and the head A afterward applied to the nail, so that the head will not be broken when the nail is driven in the wall. The outer end of the shank D may be rounded, as in Fig. 2, or pointed or tapered to assist it in entering the socket e.

Instead of the stud or shank D having the forked end f and the nail having the aperture or socket e the stud or the head A may have the socket e, and the nail have the forked end f to enter said socket, as clearly shown in Fig. 5. WVith the above arrangement the same effect is produced as with the arrangement shown in Fig. 2.

In Fig. 10 the forked stud D,which is to be secured to the head A, as in Fig. 2,is more pointed at its ends than in Fig. 2, so that it can be more readily passed into the socket e or through fabric or the like.

In Fig. 8 the outer end of one prongfof the stud or shank D is provided with an aperture h, through which the opposite prong f may be passed, whereby the stud or shank may be made to envelop a bar or other object.

In Fig. 6 the part D is shown in the form of a screw, whereby the head A may be secured in place without the aid of the nail B.

In Fig. 7 the part of the stud, shank, or screw D that enters the head A is flattened out to widen it, whereby it will be prevented from becoming detached from the head A. hen

the part D is in the form of a screw, we prefer to make the part of the shank that remains in the plate or Washer E square or flat, and to make the aperture 1) on said plate correspond. By this means, when the head A is turned, the plate or Washer E Will assist in turning the screw.

In Fig. 9 the stud or screw passes entirely through the head A and the plate or Washer E, and the stud is threaded through only a part of its length, so that it will hold the head A tight against a board or the like.

The shank D may be smooth, corrugated, threaded, apertured, or otherwise arranged, as desired;

Having now described our invention, what we claim isv 1. The shank D, having one end widened or enlarged and its opposite end forked, combined with the head A, that receives the widened end of the shank, and with the nail B, having a socket e, that receives the forked end of the shank D, substantially as described.

2. The shank D, having a square or flattened portion and a widened end, combined with the head A, into which said widened portion projects, and with a plate or washer E, secured to said head, and having an aperture 6, that corresponds in shape with the squared or flattened portion of the shank, said squared portion of the shank fitting within the aperture b, so that the shank and-washer will turn in unison, or one turn the other when the head A turns, substantially as described.

3. The shank D, having one end widened or enlarged and the opposite end split or forked, combined with the head A, that is cast around said widened end, substantially as described.
