-CUFF-PIN.

I Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed April 6.1906. Serial No.310,36l.

To all 1071 0717, it may concern:

Be it known that I, FRANK E. 'FARNHAM, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Cufl- Pins, of which the following is a specification, reference being had therein to the accomanyin drawings.

Like vetters indicate like parts.

Figure 1 is a top plan of a sheet of metal cupped up and cut to form the blank for the front or ornamental portion of my improved cuff-pin. Fig. 2 is a top plan view of the blank so formed and cut. Fig. 3 is a side elevation of said blank after its side flanges and pointed ends have been turned up. Fig. 4. is a side elevation of the pin-tongue. Fig. 5 is l a top plan view of the lining-plate with the e pin-catch and the earpieces bent up. Fig. 6 is a side elevation of the same. Fig. 7 is a view of my improved cuff-pin as seen partly in elevation and partly in central longitudinal section. Fig. 8 is a view of the same as seen partly in elevation and partly in central transverse section on line 2E of Fig. 7.

My invention relates to the class of cuffpins; and it consists of the novel construction and combination of the severalpar ts herein after described, and specifically set forth in the l claims.

In Fig. 1 is represented a piece of sheet metal, preferably gold-plated, from which the ornamental or front portion A of the cuff-pin isformed. This piece of sheet metal is cupped up, as shown at a a, preferably in the form of an elongated. ellipse or in any other suitable shape, as may be desired. This cupping-up is done by means of a die and plunger in t e wellknown manner. The sheet of metal is 1 then cut concentrically tion, but outside of the edges thereof. In

the outline of the i Fig. 1. the hole 1) represents the sheet blank which has been cut from which has been so cut.

In Fig. 2 the concavo-convex ornamental front is designated as A. There are two opposite, long, and broad curved flanges B B and also two short points or projections C C, one at each end of the blank and extending in the line of the major diameter of said elliptical cupped portion. The short curved parallel lines (designated as D D D D in Fig. 2) between the ends of the flanges metal, and Fig. 2 represents the blank itself with said cupped pore nated in Figs. 7 and 8 as B B and pin-catch F extends up points C C represent the cut edges of the stock or sheet plate contiguous to the cupped portion a of the blank. The blank is then drawn up on the sides and ends by bending the flanges B B at right angles to their original direction, as shown in Fig. 3 at B, and the points or projections C -C are bent up at right angles to their original directions, as shown in Fig. 3 at C C. The edges D D D D are left unchanged, and thus constitute recesses with the points or projections C C and the flanges B B, as seen in Figs. 2 and 3, at D D D D. r Y

E is the lining-plate, having a pin-catch F and two ears G G, all integral. The liningplate E may have the sen: icircilar notcheson its edges, as shown in Fig. 5, to serve as airholes, as is al in lining-plates for cuff-pins. These, however, are no part of my invention. The purpose of such air-holes is as follows: Jewelers in finishing cuff-pins subject them to a dipping in acid and to acoloring process. The acid is heated to the boiling'ternperature. The acid gets between the front and back plates. But for these openings it would be practically impossible to complete the drying-out process when the cuff-pins are put into hot sawdust for that purpose. The ears G G have pivot-holes, and they are spread apart, so as to be divergent, as illustrated in Figs. 5 and 8. The plate E has the two short rounded ends or tips H and H.

The pin-tongue is shown at I and has a pivot J, which is seated in the pivot-holes of the ears G G when said ears are pinched toward each other to loose contact with the bent end of the pin-tongue I. The liningplate E from the tip H to the opposite tip H thereof is precisely of such length as to fit in the cup a with said tips in abutment with the inner surfaces of the bent-up points or projections C C. (Shown in Fig. 3.) The side flanges B B (shown in Fig. 3) are then rolled over and their edges shut down tightly upon the outer surface of the liningplate, as seen in Fig. 7, but more plainly in Fig. 8. These rolled-over side portions are desig- B B. The points bent down into close or projections C C are H and H of the contact with the tip ends lining-plate E,

Fig. 7. Thus the lining-plate E is firmly fastened in the concave portion a of the ornamental or front part A of the cuff-pin. The

between the adjaas represented at 'C C in l cent ends of the rolled flanges B B and the bent-over point or projection C, contiguous thereto, and the ears G G extend up between the adjacent ends of the rolled flanges B B and the bent-over point or projection G, contiguous thereto. While the pin-catch F and the ears G G make it impossible to provide alongside of them any rolled or bentover flange, the edges D D D D furnish spaces or recesses between the contiguous ends of the rolled flanges B B and the points or projections C C. Thus although there is not a continuous roll or bend of the flanges and points the same effect in appearance is produced, and the lining-plate E is securely held in position without the use of solder.

The function of the bent-over point or projection G (which is contiguous to the ears G of the lining-plate E) is as follows: If the point or projection C (shown in Fig. 7) were omitted from the structure, there would be a liability that when the pin-tongue I is pressed down and turns on the pivot J the right-angled fulcrum-point m of the pintongue, which bears with great force upon the part of the lining-plate E beneath it, would exert a suflicient leverage to cause the tip H of said lining-plateto lift away from the ornamental portion or front A of the cuff-pin. To prevent such rise and separation, solder would ordinarily be used; but instead of I using solder for this purpose I use the bentover point or projection C, as shown in Fig. 7, which holds down the point or tip H of the lining-plate E and so prevents it from rising or separating from the ornamental portion or front A of the cuff-pin. The point or projection C, however, which is contiguous to the pin-catch F, does not serve the function above stated, because there is at that point no harmful leverage on the liningplate E, caused b the closing of the pintongue I; but the use of the point C is, first, to make the finish and shape of the two ends of the cuff-pins symmetrical, and, secondly and principally, by making the two ends of the cufl-pin alike the workman may l insert the eared portion G of the lining-plate j E in the cupped depression of the ornamental front A at either end thereof, as may be most convenient for him, and thereupon to bend over into contact therewith that point or projection C which happens to be contiguous to the tip H onthe ear end G of the lining-plate E, and that point or projection G becomes the one which prevents the said lining-plate from rising by the leverage of the pin-tongue, as described. This construction results in a very satisfactory appearance and finish, which with the comparative cheap ness of the cuff-pin so produced makes this invention a useful article.

In this invention I do tongue or lining-plate as not claim the pinmy invention, these I being well known and in common use in the art.

I claim as a novel and useful invention and desire to secure by Letters Patent 1. The improved'cufi-pin herein described, consisting of the combination of a liningplate having earpieces at one end each provided with a pivot-hole and a pin-catch at the opposite end, a pin-tongue engageable with said pin-catch, a pivot on which said pin-tongue is mounted and which extends through said pivot-holes in the earpieces, a cuppedup ornamental front plate in the concave portion of which said lining-plate fits, two integral flanges on opposite sides of said front plate which are rolled over throughout their entire extent into close contact with the outer surface of said lining-plate each of which flanges abuts at one end the pin-catch and at its opposite end one of said earpieces, J

and two integral points or projections on the opposite ends of said front plate which are bent over into close contact with the tip ends of the lining-plate respectively.

2. The improved cuff-pin herein described, consisting of the combination of plate having earpieces at one end vided with a pivot-hole and a pin-catch at the opposite end, a pin-tongue engageable with said pin-catch, a pivot on which the pintongue is mounted and which extends through the pivot-holesin the earpieces, a cuppedup ornamental front plate in the concave portion of which said lining-plate fits, two integral points at opposite ends of the front plate bent over into close contact with the ends of the lining-plate so as to abut respectively the pin-catch and the earpieces, and means adapted to secure the lining-plate to the front plates along the portions of the lining-plate which extend between said earpieces and pin-catch.

3. The improved cuff-pin herein described, consisting of a lining-plate having earpieces at one end provided with a pivot-hole and a pin-catch at the opposite end, a pin-tongue engageable with said pin-catch, a pivot on which the pin-tongue is mounted and which extends through the pivotholes in the earpieces, a cupped-up ornamental front plate having four flanged portions with four intermediate recesses or spaces, which flanged portions are bent over into close contact with the outer surface of the lining-plate the whole being so arranged and combined that the pin catch and the earpieces extend through said recesses or spaces at the contiguous ends of said flanged portions.

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