SAFETY CATCH FOR PINS AND METHOD OF MAKING THE SAME Fi1e d Feb. 1, 1935,

tit?

nt t' This invention relates to r pins for use in mounting brooches, emblems and like articles of jewelry, and to a method of making the same.

In the manufacture of brooches, emblems, class pins and like articles of jewelry, it is the usual practice to solder or otherwise secure both the pivotal joint for the pin and the safety catch either .to a bar which-supports the brooch, or directly tov the body of the brooch, and in either case it is absolutely necessary that the parts be so aligned that the pin tongue will register properly with the slot in the safety catch. This procedure not only necessitates a separate construction and assembly of both the'wfety catch and the pin joint, but also requires two separate and distinct operations in attaching these members to the brooch or bar. Moreover, the procedure is quite diflicult to carry out and requires great skill and accuracy on the part of the workman,

and in many cases involves a considerable loss of time and materials due to inaccuracy in assembling the parts.

The principal objects of this invention are to provide an improved bar pin and a method of ticle of jewelry without the necessity of using' the high degree of still now required; and to provide a pin wherein the pin joint and safety catch form an integral part of the bar, the whole constituting a compact unit wherein the parts are properly aligned so that it may be applied to a brooch, emblem or iike article merely by securing the article to the body of the bar in any suitable manner. Further objects and advantages will be appar ent from a consideration of the following de= seription and acco mying drawing, wherein:

Fig. 18 is a plan view-of one end of the i-iiv blank provided with an eye to which a chain may m attached; and

Fig. i9 is an enlarged elevation of a drive screw, used in conjunction with a bar having an aperture therein for attaching a brooch, emblem or the like article thereto.

The bar pin herein shown for thepurpoee of illustration preferably is made of sheet which ofierssubstantial advantages such, for enample, as lightness of weight, ease of wort 40 and capability of taking a fine finish, although it is to be understood that the invention is not limited to any particular type of terial, as I contemplate the use of various types oi mate which are capable of being worked.

The bar member proper is made from a tary bl i which may be stamped; or otherwise formed from a-suitable sheet of stock to provide a pair of transversely disposed wings 2 and t at or adjacent to one end and an enlarged portion 5 at its opposite ends The intermediate portion of the bar i may be shaped to provide a substantially fiat enlargement 5 which constitutes a support to which a brooch, emblem or like article or jewelry (not shown) may be secured.

The central portion of the

wings

2 and 3 are swaged or depressed along the broken lines of Fig. 4 to form upwardly projecting studs I and 8 (Fig. 5), and its enlarged end 4 is drilled or punched along the broken lines of Fig. 4 to pro-v vide a central opening III. This operation may be performed by the use of suitable dies and may 'be carried out subsequent to or simultaneously with the forming of the original blank I. The

wings

2 and 3 are then bent upwardly at an angle to the body of the bar substantially less than 90 and the opposite end of the bar is bent upwardly at right angles so that the opening it) is in substantial alignment with the longitudinal center of the bar, as shown in Fig. 5, this end hereinafter being referred to as the post. If desired,

shown in Fig. 5, preferably is formed by punching and bending the sheet metal blank as above described, various other procedures may be employed, such, for example, as coining, die-casting, etc. Irrespective of the particular process emplayed in forming the bar member, the post 4 is formed integral with the bar with the opening ill or In disposed in proper alignment with the

wings

2 and 3 which provide a support on which a pin H is pivotallyzmounted.

The blunt end of the pin N (Fig. 6) preferably is formed with fiat parallel sides and is provided with an opening l2 which conforms in size to the diameter of the studs 1 and 8. In assembling the pin I l with the bar member, its blunt end is first inserted between the

wings

2 and 3 so that the opening I2 is correctly aligned with the studs I and 8 and the wings are then bent inwardly toward each other so that the studs 1 and 8 project into the opening l2 and provide a pair of pintles which support the pin for pivotal movement toward and away from the post about an axis which is at right angles to that of the opening ID.

The keeper is formed from a blank l5 (Fig. 7) which may be stamped out from a piece of sheet metal to provide similarly shaped ears i6 and H on each end. The center of the blank i5 is punched out to form a pair of yokes l8 and I9, and one of the ears i6 is swaged or depressed to form a hollow dome or cup 20 projecting from one side of the blank and the other ear I1 is likewise provided with a hollow stud 2| which projects from the opposite side of the blank. Both the dome 20 and stud 2| are substantially circular in cross section, and their size and shape is such that the end of the stud 2| is adapted snugly to fit within the interior-of the dome 20.

In assembling the keeper with the post, the yokes l8 and is are first bent about their transverse center, as shown in Fig. 10, and the stud 2| is then inserted through the opening ID in the post, and by further bending the yokes toward each other the dome 20 is brought against the opposite face of the post so that the stud 2| projects into the interior of the dome and the yokes l8 and i9 straddle the edge of the post 4, as shown in Fig. 11. When thus assembled the ears l5 and I1 are disposed one on each side of the post and the stud 2| provides a pintle which supports the ears for pivotal rocking movement about the post. The bent yokes l8 and I9 project outwardly in the form of loops and provide convenient means for rotating the keeper about the post,

it being noted that the spaced yokes provide a recess in which the thumb or finger nail may be conveniently inserted.

Instead of forming a hollow dome on the ear IS, a countersunk or tapered opening 22 (Fig. 12) may be provided and the parts assembled as above described, in which case the stud 2| preferably projects into the opening 22 so that its outer end is substantially flush with the outer surface of the ear l6, as shown in Fig. 12.

'After having assembled the keeper and post, the final step consists of forming a radial slot 25 somewhat more than half way through each of the ears of the keeper and the post, this operation preferably being preformed by means of a milling cutter or burr 26 (Fig. 13) whose thickness is less than the inner diameter of the stud 2| but greater than the diameter of the pin The slot 25 may be formed in the upper part of the keeper and post so that it will be in alignment with the shank or tongue of the pin II, as shown in Figs. 1 to 3, in which case the ears are first swung into a position corresponding to open position in the completed article (Fig. 2) and the slot 25 then cut radially through the upper edge of the post and corresponding portions of both ears, as shown in Fig. 13. If desired, the slot may be formed elsewhere, as for example on the side of the post, in which case the ears are swung to open position and the slot 25 cut in from the side, as shown in Fig. 14. Where the post has either been formed with a slot, as shown in Fig. 5 or where the edge of the post has been slotted prior to assembling the keeper therewith, the ears are first swung into a position corresponding to the open position of the completed article and the slot 25 is then cut through the ears so that the line of cut registers with the previously formed slot or opening in the post.

The slotting or cutting operation merely removes sutflcient material from the dome 20 and stud 2| to permitthe tongue of the pin to enter the opening |||of the post, and, as shown in Fig. 15, the major portion of the dome and stud remain intact so that the pivotal support for the ears is not disturbed or in any way impaired In the completed article the ears are disposed on each side of the post and the stud 2| has a snug sliding fit within the opening Ill with its end projecting into and engaging the interior of the dome 20, thus securely locking the parts in assembled position, as shown in Fig. 15. As the various parts of the post and keeper closely interfit, there is preferably sufficient frictional engagement to prevent a free rotation of the keeper, and hence when it is swung'from open position (Fig. 2) to closed or locked position (Fig. 3), there is little or no danger of its being accidentally swung back to open position. Moreover, as both the pivotal support for the pin II and the post 4 are integral with the bar member I, there is no 'danger of theparts becoming loosened or disaligned.

Although, as previously pointed out, the member 5 provides a support to which a brooch, emblem or like article may be soldered, cemented or otherwise secured, various other means may be employed for attaching an article of jewelry to the'bar pin. For example, in Fig. 16 I have shown'a threaded stud 30 on the support 5, this arrangement being particularly suitable for use in securing various types of jewelry such as galalith, ivory, ebony, compositions, etc., and in Fig. 1''! I have shown a supporting plate 5 pro vided with a plurality of prongs 32 having beveled appease it" like article is carried by a small chain; a guard pin usually is attached to the chain, and in Fig. it I have shown a bar pin having a small ring or eye lid integral with one of the wings i, this ring or eye providing an anchorage to which such chain may be conveniently attached.

it will be noted that as the outer ends of the bent yokes l8 and I! are spaced from each other, one of-themis always in an accessible position irrespective of the relative position of the lreeper and t (note Figs. 2, 3 and it), and

hence the keeper may be quickly and conveniently'operated to lock or release the pin.

While I have shown and described one de-' sirable embodiment together with certain modifications, it is to be understood that this disclosure. is for the purpose of illustration only and that various changes and modifications both in procedure and in the construction and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may he made without departing from the spirit and scope of the invention as set forth in ,the appended claims.
