Patented May 11, 1937 JEWELRY HINGE Emil L. Johnson and Olof Lundsten, Attleboro, Mass.
Application April 22,
This invention relates to jewelry findings, particularly a spring actuated hinge which is to be attached to another part or other parts for assembly in various uses, such for instance as an ear clip, hat ornament or the like; and has for one of its objects the provision of means to prevent distortion or rupturing of the resilient portion or spring of the device.
Another object of the invention is the provision of a stop to limit theopening movement of the hingedly related parts to prevent undue tension upon the spring.
Another object of the invention is the provision of means for locating the end of the spring so that it will be in balanced relation and will be so located that the parts to which the hinge is secured will not interfere with the action of the spring, nor will the spring interfere with the positioning of the parts to which the hinge is attached.
Another object of the invention is the provision of a hinge in such position that the part mounted thereon will serve as an abutment for engagement with a part of another section of the hinge and prevent excessive movement of the hinge towards open position.
With 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 use of jewelry findings, such for instance as hinges, for connecting together two plates at least one of which is ornamentally embellished, or in other uses, it is frequent that where a spring is used for urging these plates toward closed position that an excessive movement of these plates toward open position will so deform or rupture the spring as to prevent its proper action in closing the plates or moving them toward closed position; and. in order to obviate this difficulty, we have provided a stop or some means to prevent excessive opening of the parts and thus guard against such rupture of the spring; and we have also provided an opening through which one of the ends of the spring may extend so that it can be better arranged and positioned for operation on the members with which it is assembled; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred form or means by which these advantageous results may be accomplished:
With reference to the drawing, l0 designates one member and l l the other member. This member Ill is shown as formed of flat sheet stock with ears l2 bent up on either side adjacent one end thereof, which ears are pierced as at l3 for the reception of a pintle pin. These ears are also provided with a projection or abutment M to act as a stop, as will presently be described. This plate is also offset as at [5 and is provided with an opening I6 at the offset through which one end of the spring may be passed. This offset is for the purpose of accommodating a plate or other part to be mounted on the hinge and is provided with a recess I1 extending from the opening 16 outwardly towards its free end for reception of the end of the spring so that it may be located beneath the contacting surface thereof.
The member ll consists of a plate with eyes 19 rolled on the end thereof with a notch 20 between these eyes and with a recess 2| formed in the plate on its outer surfacefor the reception of one end of the helical spring.
These members It and II are assembled and a pintle pin 2| is passed through the ears l2 and eyes [9, while a helical spring 22 embraces this pin between the eyes l9 with one portion 22 extending through the notch 20 and in the recess 2 I,
while the other portion 23 extends through the hole I6 and along the recess ll formed in the outer surface of this plate. In this manner, both the spring end extension portions 22 and 23 are positioned below the outer surfaces 24 and 25 of the plate so that the end portions 22 and 23 will in no way interfere with the mounting of ornamental members such as 26 on these hinge sections.
By reason of the offset IS the ornamental plate 25 will be located longitudinally of the hinge as will fully appear from Figure 1, and by reason of the opening IE it is unnecessary to have the portion 23 extend around the rear end of the member H) as would otherwise be necessary.
Operation In operation, the spring tends to move the members I!) and II and the parts such as 26' to which they are attached to closed position, as shown in Figure 2. These parts may be opened or moved apart about the pin 22 as a center,
but by reason of the abutment surface; M the, edge 28 of the member II will contact with these abutment surfaces and prevent opening beyond the point shown in Figure 3, or this abutment l4 may be located at some other convenient point for such opening as may be desired to limit the tension on the spring so as to prevent the spring from being stretched beyond its range of operation.
Modifications In some cases, however, instead of providing a protuberance as It for engagement with the edge 28, the ornamental plate will serve this purpose by a proper location to contact with an abutment surface on the hinge or some part movable therewith, and we have shown the ornament 29 so secured to the member ll, see Figure 8, that it will contact a portion 3| of the member [0 so as to designedly limit the opening movement as illustrated in Figure 9, where the parts 3| and 32 are in contact and thereby limit the opening movement in this manner.
In Figure 10 we provide rolled edges 35 and 36 on each hinge member and oppositely notch each of these to provide cooperating abutments 3'! and 38 for engagement to limit the opening movement of the hinge members.
In Figures 11 and 12 we have also provided rolled hinge eyes 39 and 40 on each member,
and for the stop or limiting means we raise the stock of one rolled eye to form an abutment 4| to engage the edge 42 of the plate of the other member and thus limit its opening movement.
The foregoing description is directed solely towards the construction illustrated, but we desire it to be understood that we 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.
1. A jewelry finding comprising a pair of binge members pivotally related by a hinge pin adjacenttheir inner ends and having a light spring to force the free ends together, said members having eyes at their pivoted ends for receiving the hinge pin and terminating close to said eyes and both members having portions close to said eyes adapted to abut at points close to said hinge axis to limit their opening movement to substantially less than to thereby protect said spring.
2. A pair of plate-like hinge members pivotally related by a hinge pin at their inner ends, and a spring on said pin arranged to urge the outer ends of said members together, said members having recesses and apertures opening from the ends of said recesses and said spring extending through said apertures and having its ends in said recesses so that its ends may move relatively to the hinge members even though such recesses are covered by parts connected to the hinge members.
3. A jewelry finding comprising a pair of hinge members pivotally related by a hinge pin adjacent their inner ends and having a light spring to force the free ends together, said members having eyes at their pivoted ends-for receiving the hinge pin and terminating close to said eyes and both members having portions adapted to abut to limit their opening movement to substantially less than 180, such portions on one of said members being on the eyes proper.
