13 Claims.

This invention relates to buckles, clasps and like devices for connecting the ends of wristwatch straps, bands, bracelets and similar articles and more particularly to devices in which interchangeable initial letters or other ornamental insignia. may be mounted.

One object of the invention is to provide a fastening device for straps, bands or bracelets having a novel construction and arrangement of elements for mounting and displaying interchangeable initial letters or other character elements.

Another object of the invention is to provide an extensible clasp of the type indicated comprising a plurality of hinged members adapted to be folded into overlying relationship in a cover member with means in the cover for mounting the character elements.

Another object of the invention is to provide a device of the type indicated including a movable plate which overlies the character elements to hold them in place and a slidable extension member for adjusting the length of the clasp which latter member overlies the plate and holds it in engagement with the character elements.

Another object of the invention is to provide an extensible clasp of the type indicated having a releasable detent on the retaining plate which cooperates with the adjustable extension. member to limit the outward sliding movement of the latter. I

Still another object of the invention is to provide a clasping device of the type indicated having an attractive and ornamental appearance, a simple and compact structure, and one which is adapted for use over long periods of time without repair or replacement of its parts.

Further objects of the invention are set forth in the following specification which describes a 40 preferred form of construction of the device, by

way of example, as illustrated by the accompanying drawing. In the drawing:

Fig. '7 is a view similar to Fig. 6 showing the plate folded into closed position and the extension member in position to be slid into the cover member; and

Fig. 8 is a perspective view of a modified form of character element adapted to be set in the opening in the clasp.

The present invention relates generally to an extensible clasp or buckle including a cover member in which interchangeable character elements are mounted to be exposed to View through a suitable opening formed therein. Preferably, the cover member has an o-ifset marginal flange around the opening forming a recess in which the character elements are set and the latter have extended ends which overlie the flange. A plate overlies the character elements and a removable extension member slides in the cover member and bears against the plate to maintain the character elements properly positioned in the recess. The clasp is preferably of the type in which a plurality of sections are hingedly connected to adapt them to be unfolded to lengthen the bracelet and to be folded into overlying relationship when on the wrist, but the clasp itself may take other forms. In the present embodiment of the invention the clasp is provided with a slidable extension member and ratchet or similar latching means for holding it in adjusted position. A releasable detent means is also provided on the plate which cooperates with the slidable extension member to limit-its outward movement with respect to the cover member.

Referring to the drawing, one form of clasp 2 is herein illustrated for connecting the opposite sections 3 and 4 of a two-part bracelet, but it will be understood that other forms of clasps or buckles may incorporate the novel features of the present invention. The clasp 2 as illustrated comprises three pivotally connected sections, namely: a base member I, an intermediate hinged connecting member 8 and a top member or cover 9. These several members may be constructed as stampings struck up from thin sheet-metal stock and curved slightly to conform to the contour of the wearers wrist. The base member I may be constructed in the form of a relatively flat plate I5 having side flanges I I folded upwardly therefrom. The opposite ends of the plate portion Ill extend beyond the side flanges I I and are curled around to form hinge loops I2 and I3 for connection respectively with the end link of one of the bracelet sections 3 and at the other end with the intermediate connecting member 8 of the clasp. The side flanges II have detent projections I4 at their sides which cooperate with the cover member 9 when the parts of the clasp are folded into closed or clasped relationship in a manner as later more fully explained.

The intermediateconnecting member 8 may be stamped from sheet-metal with a rectangular portion I9 having side flanges folded downwardly therefrom. The flanges 20 have extensions at one end pierced with holes to receive a hinge-pin 2| extending therebetween and passing through the hinge loop I3 .on the base member to pivotally connect the two members. At its opposite end the member 8 is bifurcated to provide spaced tabs which are curled over to form hinge loops 23. The main portion of the member 8 is cut away centrally throughout substantially its full length to provide a rectangular opening and the edges of the opening are formed with ratchet-teeth 26 for a purpose as later explained.

The top element or cover 9 is constituted by a relatively flat plate portion 30 having side flanges 3| bent downwardly and then inwardly to form opposite channels or guideways 32. A hinge-pin 33 extends through holes in the flanges 3| adjacent one end thereof and through the spaced hinge loops 23 on the member 8 to pivotally connect the latter to the end of the cover member 9. It will be observed by reference to Figs. 2 and 5 that the sections I and 8 are adapted to be folded one over the other and into the top or cover member 9, the detent projections I4 on the base member I cooperating with the spaced-apart edges 34 of the inwardly-directed portions of the flanges 3| to releasably clasp the members together.

An extension member 35, later to be more fully described, is slidably mounted in the cover member 9 and joined to the end link of the bracelet section 4 by means of a connecting loop 36. As thus far described the clasp is similar to those previously used in the art in that the three sections I, 8 and 9 can be unfolded to extended relationship to permit the bracelet to pass over the hand of the wearer and then collapsed by folding the parts into overlying relationship and into the cover member to shorten the bracelet to engage the wrist. To facilitate the opening out of the pivoted sections of the clasp the plate portion 30 of the cover member 9 is extended beyond the side flanges 3| to provide a finger-grip 31 under which the finger-nail may be inserted.

In accordance with the present invention the cover 9 is adapted to mount interchangeable character elements which may take the form of initial letters 49 or any other desired insignia. To this end the plate portion 39 of the cover 9 is formed with a rectangular opening 4| bounded by a relatively narrow upset ribbed frame 42 shaped to provide an inwardly-directed marginal flange 44 offset from the inner face of the plate. It is to be further noted that at either side of the framed opening 4| the plate portion 39 of the cover 8 is upset or raised above the plane of its lateral edge portions from which the flanges 3| depend. The eifect of this is to provide a raised panel on the top of the cover 9 and a flat recess 43 on the under side of its plate portion 30 for a purpose as later explained. The character elements 4|] may be in the form of initial letters of any suitable design, preferably of a thickness equal to the depth of the recess formed by the offset flange 44, and provided with extended end bars 45 which engage the'flange 44 on opposite sides of the opening 4|. The character elements are thus exposed to View in the opening 4| being held in their proper spaced relationship by the bars 45 the ends of which abut. Any desired combination of initial letters may be set in the recess formed by the offset marginal flange 44, or other suitable character elements, such for example as that illustrated in Fig. 8, may be Substituted. In this latter modification the character element is in the form of a plate 41 of suitable sizeand shape to fit into the recess formed by the offset flange 44 and having ornamental insignia or other embellishment 48 embossed, engraved or otherwise delineated on its surface.

A thin plate 49 of resilient sheet metal is placed in the recess 43 to cause it to overlie the character elements to hold the end bars thereof in engagement with the marginal flange 44. Preferably the plate 49 is pivotally mounted on the hinge-pin 33 in the opening between the spaced bearing loops 23 on the end of the intermediate connecting member 8. For this purpose the end of the plate 49 is reduced in width and curled over to form a hinge loop 50 surrounding the pin 33. The width and thickness of the plate 49 are substantially equal to the width and depth of the recess 43 to form a substantially flat continuous inner face on the cover member 9. Preferably, the plate 49 is convexed slightly more than the plate 39 of the cover member 9 and is resiliently held against the character elements 40 by the extension member 35 which bears against the inner face of the plate and flexes it to engage the bottom of the recess 43 in the cover member 9 above the character elements 40. At its outer free end the plate 49 is slitted and the material between the slits struck up to provide a tongue 5| for a purpose as will later appear.

The extension member 35 is constructed from a strip of sheet-metal cut away to provide a longitudinally extending rectangular opening 52. The metal at the sides of the opening 52 is bent or folded over to form upwardly extending side flanges 53 which are folded inwardly on themselves to provide opposite parallel guiding rails 54. The rails 54 are adapted to closely fit within the channels or guideways 32 of the cover member 9 to hold the extension member 35 bearing against the pivoted plate 49 while permitting the base member 'I and intermediate. connecting member 8 to be folded into overlying relationship. within the cover member 9. The end portion of the extension member 35 forms a crossbar 55 for receiving the connecting loop 36 for joining the clasp to the bracelet section 4. At its inward end the member 35 is provided with a pair of resilient pawls 56 which project upwardly into the opening 25 in the intermediate connecting member 8 when the parts of the clasp are in folded 01' closed relationship. The pawls 56 are formed with curved ends 51 which project out wardly to engage with the teeth 25 on the edges of the opening 25 in the member 8. The pawls 56 arepreferably formed from the material of the member 35 which is cut away to the proper outline and the cut-out portions folded upwardly from the stock. Preferably, the outer ends of the pawls 56 are tapered from their upper to their lower edges to facilitate the folding of the intermediate member 8 into the cover member 9. A

preferred construction of the clasp having now been described in detail, its mode of operation will be next explained.

A purchaser selects a particular bracelet and character elements such as the monogram initials 40, or an element or elements of any other suitable ornamental form, to be mounted in the clasp. To apply the character elements to theclasp the salesperson unfolds the sections 1, 8 and 9 to extended relationship, raises the pivoted plate 49 to the position shown in Fig. 6 and sets the initial letters 49 or other elements in-the recess of the frame 42 formed bythe offset mar ginal flange 44. When initial letters are used their end bars 45 are placed in engagement with the flanges 44 at opposite sides of the opening 4| with the ends of the bars 45 in abutting engagement to hold the initials in proper spaced relation. The plate .49 is then swung downwardly into position until it lies wholly in the recess 43 to overlie the character elements 40 as shown in Fig. '7. The extension member 35 is next .alined with the open end of the cover member 9 as illustrated in Fig. 7 and the side rails 54 slid into position in the guideways 32 on the cover member 9. As the extension member 35 enters the cover member 9 the end of the plate 49 yields to permit the end portion of the extension member to pass over the upstanding tongue. 5|. tension member 35 has been slid into thecover member 9 a sufficient distance to position the end of its opening 52 abovethe tongue 5I- the-end, of theplate 49 springs up to enter the tongue 5| into the opening whereby it forms a stop for limiting the outward movement of the extension member. If,-however, it is again desired to remove the extension member 35 to substitute other character elements 49, or for any other purpose such as repair or replacement of the parts, the resilient plate 49 maybe depressed by the use ofa suitable tool to release the tongue 5|. and the extento the position shown in dot-and-dash lines in Fig. 2 and pressed into the cover member 9 between its side flanges 3| to reduce the length of the bracelet. As illustrated in Fig. 5, the side flanges 29 on the intermediate connecting member 8 lie within the side flanges H on the base 1 member 1 and they detents l4 onthe side flanges ll snap under the edges 34 of the inwardly-directed portions of the flanges 3| on the covermember 9 to latch the members; in folded relationship. With the clasp closed or folded the extension member 35 lies between the intermediate connecting member 8. and the plate 49 with the upstanding pawls 56 projecting into the opening 25 in the intermediate member to engage the ratchet-teeth 26 at the sides of the opening. As illustrated in Figs. 2 and 3, the extension member 35 is extended or withdrawn to. its fullestextent and is engaged at one end of the opening 52 .by a

the upstanding tongue 5|. To. contract thelength of the clasp to closely fit the bracelet to thew-rist. the extension member 35 is slid into the cover,

After the exmember 9, the inclined or beveled sides of the relatively stationary ratchet-teeth 26 permitting the resilient pawls 56 to slide over the teeth- When the clasp has been contracted to the proper adjustment the pawls 56 engage the ratchet-' teeth 26 to hold the extension member 35 in fixed relationship with respect to the cover member 9.

- To remove the bracelet from the wrist the finger-nail is inserted under the extended lip 31 on the cover member 9 to withdraw the latter from the base member 1 by releasing the latching engagement of the detents M with the edges 34 of the side flanges 3! on the cover member.

The three pivoted sections of the clasp may then' be unfolded to an extended relationship as showninFigsi'Z and 3 to lengthen the bracelet. As the intermediate section 8 is moved away from the cover member 9 the ratchet-teeth '26 are withdrawn from engagement with the pawls 56 on the extension member 35. The extension member 35 when thus released will slide outwardly of the cover member 9 until engaged at theend of the opening 52 by the upstanding tongue 5 on'the plate 49 which forms a stop. The bracelet may then be removed over the hand; and if desired the extension member 35 may be removed from the clasp by depressing the plate 49 and tongue 5! to permit substitution of other character elements 40 for those in place. The

parts may then be reassembled and the bracelet again applied to use in the manner as previously explained. I

It will be observed that my invention provides an extensible clasp having a novel structure and" arrangement of meansfor mountingand displayingcharacter elements such as initial letters or the like. It will further be observed that the initial letters may be set in proper position. in the cover member of the clasp and the parts of the clasp quickly and easily assembled to main tain the elements in their proper relationship. Still further, it will be observed that the clasp of the present invention has an artistic and ornamental appearance, a simple and compact arraiigeinent of its elements and is capable-of being manually. adjusted to shorten the bracelet by merely sliding the extension member into the cover member.
