CONSTRUCTION OF COMBS AND OTHER ARTICLES OF HORN AND SHELL.

SPECIFICATION forming part of Letters Patent No. 235,571, dated December 14, 1880,

Application filed July 14, 1880. (ModeL) To all whom it may concern Be it known that I, HERBERT P. PREVEAR, of Leominster, in the county of Worcester and State of Massachusetts, have invented an 1m provement in the Construction of Combs and other Articles of Horn and Shell; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure l is a front view of a ladys backcomb constructed with my improvement; Fig. 2, a corresponding view of the body of the comb without the balls used therewith as ornaments; Fig. 3, a central section of one of the balls; Fig. 4, a partial section of the comb, showing the mode of attaching the balls to the comb-body.

Like letters designate corresponding parts in all of the figures.

My improvement is applicable to horn and shell combs, or combs made of a material that will soften and become flexible when heated, and again become rigid when of the ordinary temperature; and the improvement consists in the method of securing the balls or other parts made of separate pieces and attached to the comb, substantially as hereinafter specified.

By the usual mode of attaching these ornaments a piece of screw-wire is employed, screwing into the comb and into the balls, if of the same material as the comb. This mode, besides being somewhat expensive, is not strong nor secure, since the balls frequently become detached and lost.

By my improved method the comb is first shaped by cutting or sawing, so as to form semicircular or other scalloped form of de-- pressions a a in the edge or top of the comb, where the ornaments are to be applied, and on opposite sides of each depression are formed projections b 1), extending toward each other, as indicated in the drawings, and shaped to enter suitable holes in the balls or ornaments to receive them.

On the other part, each ball or other form, B, of ornament is formed with two holes or cavities, c 0, in opposite, or nearly, opposite, sides thereof, and of a size and shape to admit the projections I) b of the comb-body A. These balls or ornaments may be of the samematerial as the comb-body, or otherwise, as desired.

Thus previously formed, the parts are united in the following manner: The points I) b of the comb-body are softened by heat till they become quite flexible and can be readily bent out of their normal position. They are then bent aside (one or both) till they can admit .the ball or ornament B between them, and

are then sprung or straightened into the holes 0 0 thereof. When the material is again cooled these projections become rigid, and firmly and securely hold the balls or ornaments.

The method is cheap, as well as strong and durable, and makes a comb of good appearance.

This mode of attaching parts ,or uniting them, when made of a material capable of softening under heat, is not necessarily confined to these particular combs and comb ornaments, and it may be applied under similar circumstances in constructing and uniting the parts of other articles of such materials, and it is not essential to the invention which part has the projections and which the receiving holes or cavities.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The method herein described of securing attachable parts to the bodies of combs and other articles of horn, shell, or similar material, which consists in forming projections pointing toward each other'on one part, and corresponding holes or cavities in the other part, then softening the projections by heat and bending aside the same, and then inserting them in the holes of the other part by straightening the projections back into their natural position, substantially as and for the purpose herein specified.

2. A horn or shell comb having balls or other ornamental parts B B, partially sunk in depressions a a of the comb-body A, and held in place by projections 11 12, formed on the body and inserted into cavities in opposite sides of the said ornamental parts, substantially as herein specified.

The foregoing specification signed by me this 14th day of June, 1880.

HERBERT P. PREVEAR.
