6 Claims.

This invention relates to an improved bracelet structure of the type in which cords or other flexible members are employed for forming parts of thexbracclet, and wherein the cords or flexible ir'iembersare connected together by suitable connectingmeans *the parts of which may be adapted for detachable connection to provide a convenient means for separating the flexible members.

One object of the invention is the provision in a device of this character of novel means for securing. the end portion of a flexible member to a part of a connecting means in such a manner as to permit the detachment of the flexible member end from the connecting means when desired while holding it securely against accidental release.

Another object of the invention is the provision of readily releasable latching means between parts of the connecting means for readily separating the parts from each other or securing them together without separating either of the flexible members from its connection with the adjacent part of the connecting means.

A further object of the invention is the pro-'- vision of a novel form of clamping means for connecting one end of a flexible member with a connecting member which contains no outwardly projecting part and is normally incapable of being accidentally released by pressure or by a blow.

Other objects and advantages of the invention relate to various improved details of construction and novel arrangements of the parts as will be more fully set forth in the detailed description to follow.

Referring to the drawing:--

Fig. 1 is a top plan View of one form of watch bracelet embodying the improved structure,

Fig. 2 is a side elevational view of the same,

Fig. 3 is a bottom plan view of the connecting means for connectingadjacent ends of flexible members together.

Fig. 4 is a longitudinal sectional view through a portion of the connectingmeans, taken substantially along the line 4-4 of Fig. 3, showing the flexible member clamping means in open position and with the latch member in closed position,

55 of the connecting'means, and,

Fig; 5 is a longitudinal sectional view, similar.

Fig. 6 is a perspective view of one of the connecting members showing the clamping member in open position and illustrating the location of the flexible member ends relative to the channel portion of the connecting member prior to their engagement by the clamping member.

In that form of the invention illustrated herewith, l designates the flexible members which in the present case are shown as parallel cords formed to present adjacent ends to engage with a portion of a wrist watch or suitable attaching means carried thereby, while the opposite ends of the cords are secured in a connecting link member 2 or 3, forming part of a connecting means 4 for connecting the flexible members.

The connecting link member 2 as shown comprises a channel shaped holder 5 provided with side walls 6 each having a longitudinally extending slot l formed therein adjacent to one end thereof and having an inturned lug 8 located adjacent to the opposite end and overhanging the channel portion. A slidable clamping member 9, shaped to fit within the open side of the channel portion of the connecting link member 2, is providedwith oppositely positioned pins in extending outwardly therefrom and adapted to be positioned within the oppositely arranged slots 1 formed in the side walls of the member 2. 'The slidable clamping member 9 is of such length as to be adapted to slide beneath and be held in closed position by the lugs 8 when moved to the limit of its forward or advanced movement as permitted by the pins in sliding within the slots. l, and is so formed as to be capable of being slid rearwardly so as to clear the lugs 8 when moved to the limit of its rearward move ment as allowed by the pins in. The clamping member 9 is provided at the end opposite to that carrying the opposed pins, Ill with downtumed teeth H adapted to engage the free ends of the cords l and hold them firmly in position within the channel portion of the connecting link member when the clamping member is in its closed position. The clamping member has a plate i2 secured to or formed integral with the outer face thereof and located between the inturned lugs 8 when the clamping member is in closed position with its outer end portion underlying the inturned lu s 8.

The connecting link member 3, as illustrated herein, comprises a channel shaped holder 14 provided with spaced side walls i5 having oppositely positionedlongitudinally extending slots l6 for receiving opposed pins ll carried by a clamping member IS. The side walls 15 are the clamping member ill in closed position when it is pressed downwardly between the side walls and slid forwardly to the limit of sliding movethe pins I! in the longitution of the flexible member when the clamping.

member is in its closed position to retain the free ends of the flexible member securely in position within the channel portion of the connecting link member. The clamping member [8 is also provided upon its outer face with a plate 2| secured to or formed integral with the clamping member at the 'end adjacerpt to the teeth 20, the plate 2] being of such dimensions as to substantially flt between and appear as a continuation of the lugs l9 when the clamping memberis moved to fully closed position.

In securing the end of cords I, or other suitab'e flexible members, to the connecting link members 2 or 3, the adjacent ends of the flexible members may be positioned within the channel portion of the connecting link member, with the clamping member pressed rearwardly to the limit of its movement and tilted upwardly after the manner shown in Figs. 4 and 6 of the drawing. The clamping member may then be turned about its opposed pinswto close substantially the open side of the channel portion of the connecting link member; and slid forwardly to the limit of its forward sliding movement to bring the end portion thereof beneath the inturned lugs carried by the; side walls of the connecting link member.

When moved into this position, the downturned teeth carried by the clamping member engage portions of the flexible member ends to hold them securely within the channel portion of the connecting link member and prevent them from becoming separated therefrom accidentally.

It will be noted that the construction is such that any pull exerted upon the flexible member will tend to draw the clamping member more securely beneath the inturned lugs and thus more firmly lock the clamping member in its holding position.

Pressure may be applied to the plate l2 or 2! to press the teeth into the flexible member ends 3 v and force the clamping member forwardly beneath the inturned lugsto a position approximating the limit of forward movement of the clamping member, and when moved to such positlon the plates l2and 2| are respectively positioned between and are substantially continuous with the opposed inturned lugs to provide substantially continuous transverse surfaces and eliminate a multiplicity of sharp edges. These plates provide convenient means for engaging the clamping members in sliding them either into closed position or moving them rearwardly from beneath the inturned lugs to release the flexible member ends.

In'releasing the free ends of one of the flexible members from the connecting link member, the

clamping member is slid rearwardly to or adjacent the limit of its rearward movement as permitted by theopposed pins within the longitudinal slots. This results in suflicient rearward movement of the clamping member. so that the end will clear the inturned lugs, thus permitting it to be tilted intothe position shown in Figs. 4

2,056,328 also provided with inturned lugs l9 for holding and 6 of the drawing to permit removal of the free ends of the flexible member from the channel portion of the connecting link member.

The connecting link member 3 is provided with an extension 22, somewhat narrower than the overall width of the connecting members 2 and 3, which extension is provided with spaced side walls 23, each having a depression 24 formed therein. The depressions 24 in the opposed side walls are oppositely positioned relative to each other to receive a bail 26 carried by the connecting link member 2. A latch 21 is pivotally mounted, as at 28, adjacent to the end of the extension 22 and is capable of being moved into closed position to securely retain the bail 26 within the depressions 24 of the spaced side walls 23, the latch 21 being provided with an inturned lug 29 adapted to snap over and engage a portion 30 of the extension 22 to hold the latch securely in place and retain the bail 26 against separation from the extension member 22. The extension member 22 and latch 21 are of such width as to permit the bail 26 to be passed thereover when the latch is open in order to provide for the complete detachment of the connecting -members 2 and 3 or their separation from each other in applying the bracelet to the wrist or removingit therefrom without detaching either iflexible'm ember from its connecting link mem- 1 her and without detaching either flexible member from the watch.

' From the above it will be seen that the free ends of the cords or flexible members may be detachably secured to the connecting members 2 and 3 in such a manner as to be clamped firmly thereto, and by fastening means which present a smooth surface appearance free from any substantial projecting part, such as might inconvenience the wrist of the wearer or be liable to catch in the clothing. 'The, provision of the latching member 21 between the connecti members, and so positioned as to be operable from the side of the bracelet opposite to that from which theclamping members 9 and I 8 are operated, permits the separation or connection of the connecting members without interference with the clamping members Sand I8 so that the bracelet may be applied to or removed from the wrist without disturbing the connections between the flexible members and the watch or between the flexible members and the connecting members.

In the normal position of wear of the bracelet,

as shown in Fig. 1, the latch member 21 is located outwardly and in a position where it is readily accessible for manipulation to connect or disconnect the connecting members 2 and 3. The outer surface of the base or bottom wall of the channel portion of each connecting memher is thus located outwardly of the wrist when the bracelet is in normal position, and this base portion may be shaped or ornamented to Present an attractive appearance upon the wrist of the capable of being securely connected to the conand described. a
