JEWELRY FASTENING.

(Application led Nov. 29, 1899.)

BERNARD CONLAN, OF NEWARK, NEV JERSEY.

SPECIFICATION forming part of Letters Patent No. 645,071, dated March 13, 1900. Application filed November 29, 1899. Serial No. 758:625. (No model.)

To alt whom t may concern:

Be it known that I, BERNARD CONLAN, a citizen of the United States,residing in Newark,in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Jewelry-Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part 0f this speciiication.

My invention relates to the mechanical devices used for locking dog-collars, ladies belts, and all such like articles, and. is an imitation in its design of an ordinary padlock.

The object of my invention and the improvement thereby made in these `jewelryfastenings is that instead of having a lock as ordinarily made with a corresponding key attached by a chain to the padlock or instead of a spring device which by the manipulation of a tongue protruding into the keyhole releases the hinged curved locking-arm I have furnished a padlock of which the main body, including the larger part of said curved locking-arm, can be stamped out of sheet metal preferably or out of any other material found suitable for such purpose, the hinged member forming only a small part of the curved locking-arm, as will be observed in the ensuing description. The said hinged member further locks itself automatically to themain body, consequently obviating the use of a key or other locking means, said hinged member interlocking with the main body simply by being pressed in over it and unlocking by being pulled apart from it. This will of course reduce the cost of such articles to a great extent, besides being an innovation'on and simplification of present locking means in this class of articles.

In describing my improvement I shall call attention to the accompanying drawings, wherein like letters of reference indicate corn responding parts in the different vie-ws.

Figure 1 shows a front view of myimproved imitation padlock; Fig. 2, a similar view of the padlock to the one shown in Fig. l, having the pivoted element removed. Fig. 3 is a side view of the padlock as shown in Fig. 2. Fig. 4t is an inside view of the hinged element. Fig. 5 is a front View of the hinged element, observing it as it is attached on the padlock in Fig. l; and Fig. 6 is an outside View of the hinged element.V

A indicates the main body of the padlockthat is, the part usually inclosing the locking devices of different constructions B', the rst part of what may be in an ordinary padlock hinged at C, which, however, here forms a solid integral part of the main body A; B2, the second or upper circumferential part of the curved arm,which similarly can be hinged at either D or C, in the latter case B and B2 being solid at D, the parts B', B2, and A, however, in my improvement all forming one integral part, and finally B3 is the loose and hinged element, the attachment of which to B2 and A is as follows: A pin H secures part Ba pivotally to the part B2, thus forming a joint, and the means for locking said hinged arm Bs to the main body A is a protuberance I, stamped out on the front side of the main body A, as seen in Figs. 2 and 3, and a corresponding indentation K on the rear side. The movable pivoted element B3 is furnished with a similar protuberance and indentation, respectively, I on one of the inner sides of the hinge-leaf L corresponding to the protuberi ance I on A and KV corresponding to K.

The clasp or curved arm is made in one solid part with the main body on two-thirds of its circumference, the remaining third being pivoted and made attachable to the main I body A, as above described.A

In the use to which these diminutive padlocks have been put the strain has been generally found to act in the direction of the arn rows and and as it might be found practical and convenient to utilize them on other articles where a strain acting at a right angle to the strain indicated by said arrows-for instance, in the direction of arrows y and g/-i the element B3, which now is hinged, could then of course be madea solid part of the main body A, similar to the part B', and the part B2 be pivoted at point D and secured at point H in the same manner part Bs is for present purposes secured to the main part A. This latter method would of course in no wise IOO be any innovation on what I have shown and the `body member having a protuberanee and described in the relation of the hinged part corresponding indentation cop'erating with B8 to the main body A, for the hinged member substantially as and for What I claim, and desire to secure protecthe purposes described. v 15 5 tion for by Letters Patent, is- In testimony that I claim the foregoing I The combination in a jewelry-fastening in have hereunto set my hand this 27 th day of the form of a padlock, of a body member in- November, A.
