1 Claim.
This invention relates to a safety catch or joint; and has forone of its objects the provision of a safety catch which will be folded up from sheet stock to provide a pair of ears closely in parallel relationship and with'the base which joins the ears enlarged Without thickening the stock or increasing the weight of the catch.
Another object of the invention is to enlarge the base of a sheet metal safety catch by deflecting the Walls or ears which extend in a parallel relation so as to provide a recess on their inner surface and a bulge on their outer surface, the bulge having its lower edge in the plane of the base of the catch so as to enlarge the effective contacting area of the base that it may have a larger support to better prevent tipping over and also to provide a better and more secure holding surface for attachment by solder or the like.
Another object of the invention is the provision of a safety catch having a base enlarged sufliciently by reason of deflection of the stock so that the catch or joint may be soft soldered to an ornament or device to whichit is to be attached which was not possible because of the small area of the base heretofore provided.
Another object of the invention is the provi- Fig. l is a side elevation of a safety catch with the rotor member shown in pin stem receiving position;
Fig. 2 is a side elevation of the catch with the 40 rotor member in looking position;
Fig. 3 is a bottom plan view of the catch;
Fig. 4 is an edge view of the catch;
Fig. 5 is a central sectional view on line 5-5 of Fig. 2;
45 Fig. 6 is a plan view of a strip of stock showing different operations upon the samein formulating the catch;
Figs. 7, 8 and 9 are sectional views on line I-!, 8-8 and 9-9 of Fig. 6; 50 Fig. 10 is an edge view of the cut out blank shown in Fig. 9 as partially bent to position;
Fig. 11 is an elevation of the rotor portion of thecatch;
Fig. 12 is a sectional view on line I 2-12 of 55 Fig. 11.
A simple manner of forming a safety catch is to fold up a pre-shaped blank of sheet stock into generally U-shape. with bearing openings in the parallel ears for rotatably supporting the locking portion of the catch or for receiving the pin stem 5 trunnions for pivotally mounting the same in position. A catch so formed has a relatively small area base and is thus suitable only for hard soldering. Various arrangements have been utilized for thickening up the stock to increase the 10 base, but I have devised a manner by which the stock of such a simple U-shaped catch may be shaped to increase the base without thickening the stock; and I have accomplished this by deforming the ears prior to bending so as to pro- 15 vide a recess on the inner surfaces or portions of the ears which are toward each other and a bulge or protuberance on the outer surfaces of the ears, the stock'being all of the same thickness and the lower portion of these protuberances lying in 20 substantially the plane of thebase so as to effectively enlarge or increase its supporting and attaching area; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means 25 by which these advantageous results may be accomplished: I
With reference to the drawing, I0 designates a ribbon strip of sheet stock which may be passed through a machine having a plunger to deflect the stockat a certain desired location to provide recesses II, II in one surface and at the same time form protuberances I2, I2 on the opposite side of the sheet stock, as shown in Fig. '7, by
stretching, the stock as illustrated in this view without thickening or adding to the thickness of the stock. The next operation is to provide openingsl3' in the stock or these 'might be recesses so as'to provide bearings'for the rotatable portion to be mounted between the ears of the 40 device. After these openings or recesses are provided the blank is cut out of the sheet stock along the line I4, as shown in Figs. 6 and 9, all ready for the bending operation shown in Fig. 10, which consists in folding the ears I5 into angular relationship at such location as I6 while a stretching of the stock I! occurs so as to'provide a base I8 having an engaging or lower surface I9. The protuberances I2 have their surface 2| so lo cated that when the bending occurs the lower surface of these protuberances 2 I will be in the same plane with the surface I9 so as to provide an increased bottom area I9, H for attachment to a suitable support.
When the device is to be used as a safety catch a rotor member such as 22 having a body portion 23, handles 24 and trunnion portions 25 to fit the openings [3 will be mounted in position, as shown in Figs. 1 to 5, by the completion of the bending of ears l5 of Fig. 10, and a slot 26 in the ears and 2'! in the rotor will be cut at some suitable or desired location so as to permit the pin stem extending into the opening 28 in the rotor member to be locked by rotation of the rotor to the position shown in Fig. 2.
It will be readily apparent that recesses on the inner surface of the ears instead of openings may be provided as sometimes occurs in devices of this character, or the device may be utilized as a joint for mounting a pin stern in a rotary position instead of being utilized as a catch,'the desirable functions of enlarging the base being the same regardless of which of these uses the device is to be put.
0 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 claim.
I claim:
A finding for a pin stem for soft solder attachment comprising a base having a bottom wall and upstanding ears forming side walls, said walls being generally of the same thickness, said side walls having an outward bulge adjacent the bottom wall, and said bottom Wall being coextensive With the side walls to provide an enlarged solder surface of thebottom wall and a hollowed base, the'total soldering area of said base being at least twice the size necessary for a hard solder connection, whereby soft solder may be utilized for connection to the surface desired.
