. The invention relates to cord bracelets for wrist watches and is more particularly directed to a novel and efficient slide whereby such bracelets may be readily 'adj usted t-o properly fit the wrist of the wearer.

Cord bracelets are at present widely use to support wrist watches in position, in lieu of usual straps or ribbons, but no satisfactory means is known to the trade which will permit of the adjustment of such bracelets to the wrist. Various devices have been suggested for this purpose, but in every instance the structures have been complicated, expensive and unreliable and have not met with popular favor.

The primary object of the present invention is therefore to provide a simple, economical and reliable slide construction for the purpose stated.

In practically carrying out the present invention, the bracelet is preferably constructed from two cords. One of said cords is passed through the att-aching ring at one side of the watch and secured to one section of a suitable clasp. The other cord is secured to the other section of the clasp and from thence passes to and through a slide constructed in accordance with the present invention, beyond which Vthe cord is led through the attaching ring at the other side of the watch and then returned upon itselfV and anchored to said slide.

Generally speaking, the slide o f this invention, comprises two fundamental elements, namely, means to anchor one end of a cord thereto, and means to form ina portion of the cord intermediate its length, an offset whereby the cord is bent or caused to be diverted from a straight path, to the end that s'uliicient friction may be set u between the cord and the slide as will prec ude inadvertent slippage between them. f

In its preferred practical form, though not the exclusive one, these ends are economically accomplished by constructing the slide from two tubes, each having an interior diameter substantially equal to the diameter of the cord to be used therewith. These tubes are longitudinally bent or curved and are secured 50 together side by side in such relation that at one end of the slide said tubes will join or intersect to form a single or common outlet while at the other end ofthe slide the outlets of the respective tubes will be independent of one another and placed side by side.

"Vith this arrangement one end of the cord can be introduced into one of the twin outlets and permanently anchored within the corresponding tube, while another portion of the cord canl be passed wholly through the other tube, so as to extend from the watch to the clasp.

It will be apparent, however, that the portion of the cord that passes wholly through the slide is caused, because of the longitudi- C nal curvature of the tube through which it passes, to be diverted from a straight path or offset. Thus sufficient friction is produced between the slide and cord to preclude inadvertent slipping of the cord through the slide, whereby the parts will maintain the desired adjustment. The slide may, however, be manually shifted to `properly fit the bracelet to the wrist. v

ttention is called to the fact that with the construction described, the slide will not subject the cord toV appreciable wear or distortion. There are no movable parts to get out of order and the structure is neat and pleasing in appearance. Moreover, this arrangement readily lendsitself to ornate ormentations to suit the most fa'stidious tastes.

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawings.

The accompanying drawing illust-rates different practical embodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.

Figure l shows a bracelet embodying the present invention laid out flat.

Figure 2 is a central section through the slide illustrated in Figure l.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a view similar to Figure 2, but illustrating a modified. form of the invention.

Cil

Figure illustrates a further modified form of the invention in elevation. i

In said drawings,1 designates a wrist watch provided on its opposite sides with attaching rings 2 and 3, while the reference character 4 designates aV suitable clasp which may be of any desired construction and two detachable sections 5 and 6. The bracelet shown in Figure 1 embodies two cords. Y One cord designated 7 is formed into a loop which passes through the ring 2 on one side of the watch, both ends of the cord being anchored in any suitable way to the section 5 of the clasp. The other cord which is designated S is secured at one of its ends to the section 6 of the clasp, as at 9. From thence the cord is passed through the slide 10 of this invention and beyond the slide extends to and through the ring 3 of the watch, being thereafter returned upon itself and the same secured to the slide 10.

The slide 10 may partake of various forms, but Figures 1,2 and 3 show that which is preferred. In these views, the slide is constructed from two pieces of metal tubing 11 and 12 of substantially the same length. They are secured together at their opposite ends by soldering or otherwise and are longitudinally bent in opposite directions intermediate their ends as best illustrated in Figure 2.

Both of these tubes have an inner diameter which is substantially equal to the diameter of the cord 8 and in securing the tubes together, they are assembled as shown in Figure 2, so that at the left hand end of the slide in this ligure, both the tubes 11 and 12 will intersect or be joined together in such manner as to form a single outlet 14. ln other words,

the tube 11 is butt-soldered to the side of the tube 12 so as to close the end of the tube 11 to leave the end of the tube 12 open to provide a single outlet 14. The opposite ends of the tubes are soldered together side by side, so as to leave twin outlets 15 and 1G corresponding to the respective tubes 11 and 12.

In associating the cord S with the slide which has been described, the free end 8 of the cord Sis passed through the outlet 15 into the interior of the tube 11 and there anchored in position in any suitable way as by passing the pin 17 through the tube and cord. rlhe other end of the cord is thereupon passed through the attaching ring 3 ofthe watch and after being returned upon itself is passed through the tube' 12 as shown in this ligure.

It will be noted that where the cord passes through the tube, it is offset or diverted laterally from arstraight pathfand, accordingly, any tendency to pull` the cord through this tube 12 will result in pronounced friction because the cord lits fairly tight within the tube. It will be clear, however, that if it is desired to adjust the bracelet by increasing or decreasing the distance between the clasp and the watch 1, the slide may be manually moved by hand by imparting thereto suliicient force to overcome the friction between the cord 8 and the tube 12, but this friction is normally sufliciently great to effectually preclude slipping stantially aline with the direction of pull of the cords so that the cords will not wear at the outlets.

The structure shown in Figures 1 to 3 isV particularly adapted for the purposes stated.V .The contour of the construction is symmetrical and readily lends itself for employment as a backing for jewels or other ornamentation which it may be desirable to mount thereon. We may, however, construct the slide in other forms than that already described and in Figures 4 and 5 two other constructions are illustrated. Here the two tubes 11 and 12Z1 are longitudinally curved, but are brought together at only one end of each, so as to form a substantially Y-shaped slide. The free end of the cord 8 is anchored within the tube 11a. while the intermediate portion of the cord passes unobstructedly through the tube 12L which is longitudinally bent to produce the friction desired.

Another modified form of construction is illustrated in Figure 5. Here the slide is y self and passed through the ring 20, the rings 21 and the ring 19 in succession.

l/Vhere this returned portion of the cord partially embraces the core 18, it is diverted from a straight path or offset for the purpose of producing suiicient friction with the core to preclude inadvertent shifting of the cord relative to the slide. Y

The foregoing different slide constructions rco are illustrative of 'different ways of adjusting l the cord of thev bracelet of the character under consideration, but, in practice, it is found that the structure of Figures 1 and 2 is the most desirable, although not exclusive. Y The foregoing detailed description shows illustrative forms of the present invention, but the'invention is to be understood as fully commensurate with the appended claims.

Having thus fully described the invention, what we claim as new and desire to secure by Letters Patent is:

1. A slide for cord'wrist watch bracelets comprising a body portion having a passage extending for substantially the full length of the body and throughwhich a cord mayeX- tend, said passage being shaped to divert or offset the cord from a straight path and of a size to snugly embrace the cord to thereby preclude inadvertent movement of the cord through said passage, and means for anchoring one free end of the cord to the body por7. tion.

2. A slide for cord wrist watch bracelets comprising a tubular body having therein two longitudinally curved passages through one of which a cord is adapted to be passed and into the other of which the free end of the cord may be inserted, said passages being of a size to snugly embrace the cord, and means to anchor the free end of the cord within said body.

3. A slide for cor'd wrist watch bracelets comprising a tubular body having therein two longitudinally curved passages, one of which extends for the full length of the body l and is open at both ends, and the other of which extends from one end of the body and abuts the wall of the other passage, whereby the body has one inlet at one end and two inlets at the other end, said passages being of a diameter to snugly embrace a cord adapted to be passed through one of said passages and one of its free ends inserted into vthe other passage, and means to anchor said free en'd of the cord in the latter passage.

4. A slide for cord Wrist watch bracelets comprising a tubular body having therein two longitudinally, oppositely curved passages, one of which extends for the full length of the body and is open at both ends, and the other of which extends from one end of the body and abuts the wall of the other passage adjacent the other en'd of the body, whereby the body has one inlet at one end and two inlets at the other end, said passages being of a diameter to snugly embrace a cord adapted to be passed through one of said passages and one of its free ends inserted into the other passage, and means to anchor said free end of the cord in the latter passage.

In testimony whereof We have signed the foregoing specication.
