Patented Mar. 24, 1936 FINDING FOR 7 CATCHES OR PINSTEM JOINTS AND llIETHOD OF MAKING SALIE Eugene Morehouse, Providence, R. I., assignor to B. A. Ballou & 00., Inc., a corporation of Rhode Island Application December 10, 1934, Serial No. 756,734 6 Claims. (01. sea-160.6)

This-invention relates to a finding for a catch or pinstem joint, and has for one of its objects the provision of a larger soldering base for better securing the catch or joint to an article to which it is to be attached.

Another object of the invention is to provide a construction having such an enlarged soldering base in the direction of the pivotal axis of the .member pivoted between them, and yet one in which the'arms which pivotally support the rotatable member will be closely related to each other. r

Another object of the invention is the method of construction of catch or joint in which the extent of the base in the direction of the pivotal axis will be unlimited by the location of the arms in close proximity one to the other. Another object of the invention is the provision of a construction of finding which may be cut out of sheet stock all of a single thickness and then by simply bending formulate a finding of the desired shape.

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

In the accompanying drawing:

Fig, 1 is a side elevation of the safety catch embodying my new finding and illustrating the base of the article to which it is attached in section;

Fig. 2 is a section on line 2-2 of Figure 1;

Fig. 3 is a top plan view;

Fig. 4 is a perspective view of the blank from which the base and spaced arms are formed for mounting the rotatable member;

Fig. 5 is a perspective view of blank of Figure 4 bent into position;

Fig. 6 is a perspective view of a similar but modified construction for use as a pinstem joint.

It is desirable to provide a large base for soldering a pinstem joint or catch to the back of a bar pin or other article to which it is to be attached. It is usual to bend up a pair of arms from the base so that these arms will extend at right angles to the base; and by reason of this construction, the extent of the base in a direction parallel to the axis of rotation of the rotatably mounted part is limited to the distance between the outer surfaces of the arms, and in order that this dimension may be increased, I have b'ent these arms back upon the base through substantially 180 and then again bent them to extend outwardly at the proper location to secure the desired spaced relation between the arms for receiving a part of the rotatable member to be mounted between them. In this manner I may extend the dimension of the base in this direction indefinitely and yet provide a construction made out of sheet stock all of one thickness, and this construction may serve to pivotally mount a keeper for the pinstem or may pivotally'mount the end of the pinstem to serve as a joint for the same; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred 7 means by which these advantageous results may be accomplished:

With reference to the drawing, l0 designates generally a blank cut from sheet stock of a uniform thickness, although the uniform thickness is not essential. There is provided a center portion II the edges of which bulge outwardly as at I2 and I3 on its opposite sides and provides the portion which becomes the base of the finding. Extending'in opposite directions from this base, there are arms I4 of duplicate construction, which are folded at substantially line l5 through 180 back upon the base to contact the base and extend toward each other, as at l6, and these arms are again bent as at I! through substantially 90 to extend away from the base and at a'location so that the distance l8 between the arms is of the desired amount. By this method of folding, the base may be cut out any desired dimension in the longitudinal extension of the blank, and by selecting the desired length of arm M to extend back over the base, the proper distance between the arms in their folded up portions I9 is secured.

These portions H! are provided with openings 20 and slotted as at 2|. The opening 20 pivotally mounts keeper'22 which is provided with a slot 23 so that when in one position it registers with the slot 2| for the reception of a pinstem to be then rotated by means of handles 24 or 25 into the position illustrated in Figure 1 or 2 to lock the pinstem in position while a rotation in the opposite direction will cause alignment of the slots and to be removed from its locked position in these arms.

The bulging portions 12 and I3 are unlimited in extent or shape and may be extended to secure the enlargement of the base at right angles tothe pivotal axis of the rotating member for soldering the base to a bar pin or other ornament 26 to which the same is to be attached. The construction which I have above referred to also allowing the base to be extended in the direction of the axis of rotation of the rotary member.

The construction which I have above described will be also followed for providing a pinstem joint. In this case, however, an opening 28 is provided through the enlarged circular end 29 of the arms with no slot extending to or from this opening. Thus these arms receive between them the circular looped portion of the pinstem having a pivot pin opening therethrough which will register with the opening 28 through which a pivot pin may extend for riveting and holding the parts in position, or the pin stem may have an integral T-shaped joint end which will be positioned between the portions 29 of the arm before folded to finished position in the same manner as the positioning of the keeper 22 so that when folded to finished position the trunnions on the end of the pinstem joint will be retained in desired p-ivotally mounted position in the finding.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. The method of providing a finding for a solder attachablejoint or catch with an enlarged base, which consists in cutting from sheet stock a strip having the desired sizedbase located centrally, and arms extending in opposite directions therefrom, bending the arms toward each other to extend over the base and again bending the arms at a point spaced from the first bend to extend away from the base, said second bending being located to provide the proper spacing of the arms apart for the reception of a member rotatably mounted therein.

2. A finding for a solder attachable joint or catch comprising a solder base, a pair of arms integral with the edge of the base and extending upwardly therefrom, at least one of said arms being folded back over the upper surface of said base and then away from the base at an angle to the base, whereby a base of a desired size substantially greater than the distance between said arms is provided.

3. A finding for a solder attachable joint or catch comprising a base, a pair of arms integral with the edge of the base, each of said arms being folded toward each other over the upper surface of said base then away from the base at substantially right angles to the base and in spaced relation to each other, whereby a base of a desired size substantially greater than the distance between said arms is provided.

4. A finding for a solder attachable joint or catch comprising a solder base, a pair of arms integral with the edge of the base and extending upwardly therefrom, at least one of said arms being folded back over the upper surface of said base and then away from the base at an angle to the base, said base bulging on either side of said arms to enlarge the same and provide a relatively large soldering area.

5. A finding for a solder attachable joint or catch comprising a solder base, a pair of arms integral with the edge of the base and extending upwardly therefrom, at least one of said arms being folded back over the upper surface of said base and ,then away from the base at an angle to the base, the under surface of said base presenting a smooth uninterrupted solder surface whereby a base of a desired size substantially greater than the distance between said arms is provided.

6. A finding for a solder attachable joint or catch comprising a solder base, a pair of arms integral with the edge of the base and extending upwardly therefrom, at least one of said arms being folded back over the upper surface of said base and then away from the base at an angle to'the base, said base bulging on either side of said arms to enlarge the same and provide a relatively large soldering area, said base presenting a smooth under surface contacting substantially throughout its length and width with the "portion to which it is attached.
