SPECIFICATION forming part of Letters Patent No. 794,368, dated July 11, 1905.

' Application filed January 21, 1905. Serial No. 242,081.

To all whmn it may concern:

Be it known that I, CHARLES F. MARK- HAM, a resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins; and I do hereby declare that the following is a full, clear, and

exact description thereof, reference being h ad to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the manufacture of pins, such as are used principally for ornamental wear, and the essential feature of this invention is to construct the body of the pin so that the joint in which the pin-tongue swings and also the catch for retaining the point of said pin-tongue are both made integral with the body portion of the pin.

Another feature of the invention is to provide a spring-finger also made integral with the said body portion, against which finger the spring-tongue joint may press to produce aspring tension at the point of the pin-tongue and cause it to be retained in the catch.

The invention is fullyset forth in this specification and more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an enlarged view of a complete pin, showing the body portion made in my improved manner and the pin-tongue in place in the joint and catch. Fig. 2 represents a plan View of the blank of the body portion, which is preferably cut from sheet-stock. On this blank is represented the catch, the two ears for the joint, and the spring-finger, all integral with said body portion. Fig. 3 is a sectional view representing the body portion as struck up into a cupped or shell form, showing the ears, catch, and spring-finger in position to receive the pin-tongue. Fig. 4 is a sectional end view of the body portion of the pin on line 4 4 of Fig. 3, showing the ears bent straight down to form the joint. Fig. 5 is a section through the catch on'line 5 5 of Fig. 3, show ing one form of catch member. Fig. 6 is a sectional view through the joint of the pin, showing the ears drawn in to receive the pintongue, which form is taken when the body portion of the pin is too wide to allow of these ears being bent straight down in the form shown in Fig. 4. Fig. 7 is a sectional View through the catch, showing the same also drawn in to correspond with the shape of the ears, as shown in Fig. 6. Fig. 8 is a central sectional elevation showing the body portion with the pin-tongue mounted therein and illustrating the spring-finger as exerting a tension on the said spring-tongue to hold the same in the catch.

Referring to the drawings, at 1 is the body portion of the pin, that is preferably struck up from sheet metal. The essential feature of this invention is that this blank is cut in such aform that the two joint-ears 2 2, catch member 3, and also the stock for the springfinger 4, are formed around its outer edge, thereby providing a body portion, a joint, a catch, and spring-finger all in one piece. After the said body portion 1 has been blanked out into the form shown in Fig. 2 it may be drawn up into the form shown in Fig. 3 or any other desired form, and at the same time the said ears, catch, and finger may be bent up into the position shown in Fig. 3 'ready to receive the pin-tongue.

When the body portion of the pin is the proper width at its ends, it is only necessary to turn the ears and catch straight down, as illustrated. in Figs. 4 and 5, to receive the pintongue; but when the end of this body is too wide the ears may be carried in toward the center and then turned down, bringing them closer together, as illustrated in Fig. 6, in order to be the proper distance apart to receive the joint end of the pin-tongue. When these joint ears are contracted in this manner, the catch may also be carried inward, as shown in Fig. 7, to correspond to the shape and position of said oint cars.

It is found in the practical use of pins of this description to be necessary to provide a spring element to exert a tension on the pin-tongue in order to prevent the point of the same from being disengaged from the catch, and to accomplish this result I have formed this tongue or finger 4 on the end of the blank and turned the same under the body portion between the ears 2 2, and thereby caused said finger, which is stiff and possesses the spring element of the metal, to engage and rest on the turned-up end 5 of the joint of the pin-tongue 5 as the point is brought up to the catch and offer a spring resistance to the closing of the said pintongue and cause the point end to be retained in the catch so that it cannot be inadvertently disengaged therefrom. The ad vantages of this construction are obivious to the trade. The body portion of the pin, including the joint and catch, may be manufactured much more rapidly by being struck up entirely from one piece, and the same may be produced with much less expense. These pins are also much stronger when constructed in this manner than when the joint and catch are soldered to the body portion, and the pins thus constructed also present a much more finished and a neater appearance.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An article of manufacture comprising a pin provided with a body portion cut from sheet-stock, said body having oppositely-arranged lateral ears located adjacent one end and a laterally-extended catch member adjacent the other end, said ears and tongue being bent over to form a joint and catch, respectively for a in-tongue, and a pin-tongue mounted in sai joint.

2. An article of manufacture comprising a pin provided with a body portion cut from sheet-stock and havin a reduced portion or tongue at one end, sai body also having oppositely-arranged lateral ears adjacent said reduced portion, and a laterally-extended catch member adjacent the other end, said ears and lateral tongue being bent over to form a joint and catch respectivelyfor a pin-tongue,

and a pin-tongue mounted in said joint, said I CHARLES F. MARKHAM.
