Fig. 10 is a sectional `view of a stillfurtherI VWatchilug `it is found that the distance between the lugsoffdifferent wrist watches varies, and in orderthat theend connection between the watch andthe bracelet may tthe lugs,- it has been customarytomakeend hooks of varying lengths and detachthemfrom the bracelet and interchanging itwithV a hook of the desired. dimension for the.` wrist watch. Other methods have been to provide connecting means to be substituted for `the' Apin whichis furnished with the wrist watch and extendsbetween thelugs. Such means may beY that which projects solid `parts with reduced portions toextend into' the openings in the lugs. These. openings varyk in size, and this method has not been entirely satisfactory; and further, the pins are not of the ornamental character desired. In some instances, attachments have been formed where theprojecting parts are'on a buckle or some other portionwhich is to receive hollow ends ofI asolid portion;` but nowhere am IaWare that L there Yhas been an arrangement which will recleive the pinv furnished with the wrist Watch which isof asizei-toaccurately fit between the lugs .and to coventhis pin" by forming an ornamental portion 4whichwillV extend the entire distance between thelugs of varying sizes; and I have accomplished this by, providing tubular portions with aspringrbetween them all housed in a tubular body; sothat the length of the body may be the minimum ,distancebetween lugs to be ac U commodated andthe tubular body plus the ex` tended-:tubular members may be the maximum distance betweenlthe lugs` to be accommodated; and `theyfollowing is a more detailed description of Vthe present. embodiment of this invention, illustrating-the preferred means bywhich these adyantageous Aresults may beaccomplished; A

With reference to the drawing, I0 designates thetwristmwatch .having lugs I I extending out- Wardly .therefrom with a:pin l2 extendingfbetween these lugs which may or may not embody a spring arrangement for detachment from position. The bracelet to be attached to the Watch is designated i4, and, is provided with Va connecting device which is commonly called an end hook and which Iv designate generally l5.

This end hook is illustrated as provi-ded with a tubular body I6 having slots Il on the under side thereof. Within this body I have provided extension members. I8 which are slidably mounted and ofy a size to fit rather snugly therein andbe guided thereby. Each of these members consists essentially of a tube which is provided with a pin i9 to extend into the slot H in the body and be limited in its movement by the length of the slot and the pin abutting the ends thereof.

The extension members I8 are forced outwardly by a spring 20 of a helical formation and held under compression between the ends 2l of the tubes I8 so that it continually tends to force the tubes I8 outwardly regardless of the position which they assume relative to the body in which they are slidably mounted. `'Ihe spring 2|,is of a helical formation providing a clear opening through the center thereof which aligns with the opening 22 in the members I8 and provides a central opening through all of these parts for the reception of the pin I2 which extends therethrough and into the lugs II. This pin willbear in the bores 22 in the tubes I8 rather than on the spring, thus allowing the spring freedom of movement to actuate the tubes outwardly.

When the tubes are at their full extent outwardly, as shown in Figures 2, 3, and 4, the maximum distance between the lugs II will be provided for, and the pin I2 extending therebetween will be completely covered byfthese ornamental tubes I8. However, when the distance between the lugs is of lesser extent, the tubes may be forced inwardly slightly or forced inwardly sumciently to accommodate the lesser distance between the lugs and where the minimum distance of the lugs is encountered,.the tubes will be completely housed within the body I6 'so thatv they will not be visible at all and the body I6 will occupy the full space between the lugs. By this arrangementan end hook is provided which will be of universal application to the lugs of awrist watch or to some other like article to which it may l be desired to attach it.

I have illustrated in Figures 1 to 8 the body I5 of the end hook as formed integral with the bracelet band I4 by rolling the same from the end of the stock thereof, and when forming the end hook in this manner, I may slot the end of the band in the portion which is toY be rolled and roll it about the end tubes with their projecting pins I. and spring 20 at the time which :it is formed into the tubular shape of the body IC, thus providing a simple means of assembly.

In Figures '7 and 8 I have reversed the construction of the stop arrangement by providing a pin 25 inthe body I6 of the' end hook and a slot 2l in each of the tubular members, where otherwise the structures in Figures 7 and 8 are like the structures in the provision in Figures 1 tot.Y

In Figure 10 I have illustrated the tubular body It as formed separate from the band designated 21 and soldered to it as at' 28, by which arrangement I may provide a seamless tube, designated 29, if desired, and cut the slots therein for the pin I9.

In Figure 9 I haveillustrated the body I6 as provided with a loop 30 to which a connecting link 3| is attached to join it to the end link 32 of the bracelet, or any other suitable means may be provided for attaching this connector or end hook when used for connecting a bracelet to the part to which it is desired it should be detachably connected.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

l. An end hook for a bracelet comprising a tubular body and a pair of tubular members slidable with reference to said body and located therein to extend the effective length thereof at each end thereof, resilient means having a center opening acting on said members to force them out- A wardly, and means for mounting said body and member on the end of a bracelet band, said body, member and spring having openings extending completely through the center thereof for the reception of the pin of Wrist watch lugs or the like.

2. An end hook for a bracelet comprising a tubular body and a pair of tubular members slidable with reference to said body and located therein to extend the effective length thereof at each .l

end thereof, a coiled spring acting on said members to force them outward1y, cooperating means between said body and members to limit the outward movement of said members, and means for mounting said body and member on the end of a bracelet band, said body, member and spring having an opening extending completely through the center thereof for the reception of the pin of wrist watch lugs or the like.

3. An end hook comprising an embracing body member, similarly shaped members of a size to ilt therein and slidably mounted with reference thereto, and resilient means acting on theA ends of said slidably mounted members to move them outwardly from the body member, said body,

member and spring having an opening extending completely through the center thereof for the reception of the pin of wrist watch lugs or the like.

4. An end hook comprising an embracing body member, similarly shaped members of a size to iit therein and slidably mounted with reference thereto, and a coiled spring acting on the ends of said slidably mounted members to move them outwardly from the body member, said body, ,i

member and spring having an opening extending completely through the center thereof for the reception of the pin of wrist watch lugs or the like.

AUGUST F. KRAEMER.
