Application filed April 30, 1909. Serial No. 493,083.

This invention relates to pins, and has for its object to provide a pin body ofimproved construction in which the pin-tongue joint and catch members are formed integral with said body, the back wall of the joint member being arranged to provide arest or fulcrum against which the rear end of the pin-tongue may rest to effect a spring pressure when the point engages the catch member.

In the ordinary beauty or cuff-pin where the joint ears are formed integral with the:

body portion, and in which the old style pin-tongue is mounted, it is found necessary to either form the body of the pin very shallow or to build up on the inside of the body in order to obtain the necessary rest or fulcrum bearing for the pin tongue. In my improved pin th1s difficulty is entirely obviated and two essential advantages are obtained.

First, when the joint members are formed on the end of the body there is no waste whatever in the stock or sheet metal from which the same are cut. This is a great. saving over the old method as when the ears are formed on the side of the blanknearly onequarter of the stock is wasted. Second, the head of the pin-tongue is formed with a fulcrum surface on the side opposite to that from which the stem projects and a rear wall is formed between the joint ears to serve as a support against which the back end of the pin-tongue may rest to pro vide the necessary fulcrum therefor. By this construction where the rear of the joint member orpin body forms the fulcrum itis apparent that the shape, including either the depth, width or length of the pin body, is in no way restricted, asis the case when the old style joint and pin-tongue are used.

lVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure '1 is a perspective view illustrating the back side of a pin body, showing the joint and catch members as being formed on the ends of said body and integral therewith, the same whenbent in position being set inward from said ends. Fig. 2--v is the blank from whichsaid body is formed showing the point and catch members as made on the ends thereof. Fig. 3- is a central, longitudinal, sectlonal view showing a pin-tongue of my improved construction mounted in the in and receiving its rest or fulcrum bearing against the wall at the rear of its pivoting point. Fig. 4; is a body formed similar to that in Fig. 1 with the exception that the joint and catch members are not set inward from the ends thereof. Fig. 5 shows the blank from which the body illustrated in Fig. 4 might beformed. Fig. 6- shows my nnproved pin-tongue provided with a head which has a fulcrum surface on its rear face opposite to thatfrom-which the pin stem projects. Fig. 7 shows another or circular form of pin, buckle or brooch, the ring being formed with a thin attaching edge.

Referring to the drawings, 1 is the pin body which iscut or blanked out of sheet material in the shape illustrated in Fig. 2, and subsequently struck or drawn up into any desired shape or form.

Theessential feature of my improvedpin body is that the joint ears 2 are formed at the end of the body portion instead of on the side thereof, said ears being connected to this end by the neck or tying web 3 andare pierced with the pivot receiving holes 4. At the opposite end of this blankis formed the catch member 5 which maybe made in any desired or convenient shape. When this blank is struck by the die-it is drawn up into the desired form and the ears may be turned inward to theposition illustrated in Fig. 1, the neck. portion 3 being also bent to carry the joint portion inward from the end of the pin body. The catch member is also formed into the desired shape and may be set inward as at 6 so that both the joint and catch members may be entirely hidden beneath the pin when the same is worn in the garment. If desired, the blank may be out in the form best illustrated in Fig. 5, in which the neck portion 7 is made considerably shorter so that when turned up the rear wall of the oint member may be substantially flush rearwardly projecting fulcrum portion 01 bearing surface 10, said portion being opposite to that from which the pin stem 8 proects. V

In order to mount the pin-tongue 1n the pin, the head of the former may be piercedv at 11 to receive the pivot pin 12 which receives its bearings in the joint ears 22, as illustrated in Figs. 1 and 3, or any other convenient method of mounting this pin-tongue in the joint may be employed.

The essential feature of my improved'pin is that the same is provided with a rear fulcrum wall 13, which Wall or abutment may be a portion of the body proper or which may be the web or stock between the joint ears, the same being adapted to serve as a rest or support against which the rear end 10 of the pin-tongue may be pressed for effecting the spring tension necessary to retain the pin point in the catch member. It Will be noted that the abutment-13 is subtantially perpendicular to the plane of the body 1 and at the rear end of said body. By the rear end I wish to be understood as referring to the end farthest from the end to which the catch member is applied.

Another form of pin or brooch body is illustrated in Fig. 7. The strongest and most practical way of attaching the old style pin joint and catch to a circular mounting or body of this construction was to solder a bar across the back of the same and then attach said members thereto, or in some cases where the stock was heavy enough the joint and catch members might be soldered to the edge of the ring 14:. But either of these methods would be unsatisfactory, one being clumsy and the other too weak to withstand the strains required of it, while by my improved ,method of forming the joint ears integral with the stock and utilizing the bridge or Wall 13 between said ears as a support,'rest or fulcrum against which the rear end of the pin may rest I have solved the problem of attaching in a practical way the joint and catch members to articles of this or a similar character.

The bearing portion 10 of the pin-t0ngue 5 presses against the neck 3 or? at a point between the pivot 12 and the base of said neck. Whether the neck is formed as at 3 in Fig. 1 or as at 7 in Fig. 4:, it is of course flexible and since it constitutes an integral transverse portion of the sheet metal body, it imparts a spring action to the pin tongue 8 so that the latter may be quite rigid if desired.

As is Well known, devices of this character are so constructed that the point of the pintongue shall be held in the catch by an outward spring pressure. Usually this is obtained by the resilience of the pin-tongue itself. If the pin-tongue is a large one, the resistance is frequently unnecessarily strong. With the structure illustrated herein such resilience as is possessed by the pin-tongue is added to by the resilience of the transverse neck 3 or 7 therefore rendering it easier to insert or remove the point of the tongue 8 in or from the catch 5. This resilient action of the neck 3 or 7 is effected by the fact that the portion 10 of the pintongue bears against the neck 3 or 7 at a point between the pivot 12 and the base of said neck. This feature of construction is especially advantageous when the pin-tongue is a short one so as to possess little or no inherent resilience.

By the use of my improved pin body and pin-tongue I greatly reduce the expense of producing this class of pin and also am enabled to produce pins of any shape and of unlimited depth.

' Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is:

1. A pin comprising a body formed of sheet metal having ears bent to form a pin tongue joint and an abutment wall substantially perpendicular to the plane of the said body, and a pin tongue pivotally mounted between said ears and having a rearwardly extended portion arranged to bear against said abutment when the pin is closed, said abutment being located to the rear of the pivotal connection.

2. A pin comprising a body formed of sheet metal having a pin tongue joint formed of spaced apart ears connected by an integral tying web arranged substantially perpendicular to the plane of the said body, and a pin tongue pivotally mounted between said ears and having a rearwardly extended portion arranged to bear against said abutment When the pin is closed, said abutment being located to the rear of the pivotal connection.

3, A pin comprising a body formed of sheet metal having an integral neck portion provided with spaced apart ears and an intervening integral abutment wall perpendicular to the plane of the said body, and a pin tongue pivotally mounted between said ears and having a rearwardly extended portion arranged to bear against said abutment when the pin is closed, said abutment being located to the rear of the pivotal connection.

4. An article of the character described, comprising a body portion provided with a catch and joint member, said joint member having a closed rear end and a pin-tongue mounted in said joint member and provided with an enlarged head extending at an obtuse angle to the body of the pin-tongue and having a tail portion adapted to engage the closed rear end adjacent the body porpin-tongue is moved to gage the inner surface of said closed rear end when the pin-tongue is moved to open position and with a tail portion adapted to engage said closed rear end adjacent the body portion when the pin-tongue is moved to closed position.

In testimonywhereof I aflix my signature in presence of two witnesses.
