BRACELET HOOK.

Application filed February 3, 1926. Serial-No. 85,789.

This invention relates to an improved construction or bracelet hook employed more particularly for detachably connecting the ends of a bracelet to a wrist watch or the like; and the object of this invention'is to provide an improved construction of such a hoolr, the same having a closing tongue or member pivotally supported in the hook member intermediate its ends, a portion of the tongue on one side of the pivot being` ar` ranged to close the hoolr and a. presser pin or member being arranged to operate upon this tongue on the opposite side of its pivot pin and to be engaged from the front of the hook to swing the tongue to open position.

Vfith these and other objects in view, the invention consists of certain novel features of construction7 as willbe more fully described, and particularly pointed out in the appended claims. l

In the appendedel'aims,

Figure 1 is a perspective view of my improved hook showing `the presser pin for operating the closure tongue. y. i

Figure 2 is a perspective view of the under side of the hook showing one of the side walls partly broken away to illustrate one of the pivot eyes as employed insupporting theJ pivot pin ofthe closure tongue.

Figure 3 is a central sectional elevation of my improved bracelet hookshowing the tongue in closed position.

Figure i is the same as Figure 3, showing the tongue in open position.

Figure 5 is a section on line 5-5 of Figure 3.

Figure (ijshows the blank as cut from sheet stock from which the hook member is formed by a folding operation.

Figure 7 shows the tongue member as cut from sheet stock beforeI being folded into working shape.

Figure 8 shows the tongue as folded into operating form.

Figure 9'is a detail of the tongue operating spring. t

It is found in practice somewhat difficult to release tne ordinary bracelet hook from the bail of a wrist watch where it is neces- 0 sary to cause the finger to engage and lift the closing tongue from the under side of the hook suiiiciently to detach the same; and to obviate this difficulty and permit this hook to be more readily detached from the watch bail, I have pivoted the hook-closing tongue intermediate its ends, that portion forward of the pivot being arranged to close the hook, while that port-ion on the other side ofthe pivot is arranged to be acted upon by a presser pin or member which ex tends through the front plate of the hook, whereby a slight Apressure upon this pin serves to lift the closure portion of the tongue to release the hook; and the following is a detailed description of the present embodiment of my invention showing one arrangement of closure member for the hook by which these advantageous results may be obtained.

With reference to the drawings, 10 designates the body portion of my improved bracelet hook which is formed of sheet stock, the outer plate 11 having a broad face which is widened at one end and folded over to form a hook 12, the opposite end portion 13 of this plate being preferably made narrower and folded around beneath the front plate, and the side wings 14 are turned down toy` form i side walls with their edges 15 turned over those of the back plate to form a body portion or housing. The free end of this under plate portion 13 is preferably notched as at 16 to provide spaced finger `portions 17 which are rolled over to form bearings for the pivot pin 18. The side walls 14 are preferably formed a little shorter than the top plate at the rear end of the hook body providing openings 19 through which the next link or bracelet element 20 may be connected thereto.

In order to provide means for closing this hook so as to prevent its accidental release from the bail 21 of the watch or other device to which it is connected, I have formed a tongue member 22 having spaced fingers 23 formed thereon, which are rolled over to form pivot eyes 24 to receive the pivot pins 18. A portion 25 of the tongue forward its pivoting point is preferably formed of the same general width Vas the end of the hook and is designed to swing against the inner edge of the hook to close the same while that portion of the tongue 26 on the opposite side of the pivot pin is preferably reduced in width and is provided with an enlargement 27 which is herein shown as being folded into a hollow button form to provide a so-called presser pin or member 28 which is arranged to extend preferably up through a hole 29 in the front plate of the body of the hook.

A coiled spring 32 is mounted on the pivot pin 18 having arms 30 and 3l arranged to act upon the closure portion 25 of the tongue to normally hold it in closed position so that when it is desired to open the same to permit the hook to be disengaged from the watch bail, it is o-nly necessary to engage the presser member 28 and force the same down or inward, which serves to lift this closure portion of the tongue there-by permitting the hook to be disengaged from'the bail yand that without the necessity ofreaching under the hook to lift the tongue from the under side thereof. Y f Y My improved hook is very simple and practical in construction, is eifective in its action and by providing means in the closure member an inward pressure is required to release the hook tongue instead ofby a lifting or outwardly pulling action whereby the chances of inadvertent release of the closure member is minimized. i

4The foregoing description is directed solely towards the construction illustrated, but Iv desire it to be understood that l' reserve theprivilege of resorting to all the mechanical changes to which the device is suseepti ble, the invention being defined and limited only by the terms of the appended claims; Iclaim: y Y f l. A bracelet hoolr formed of sheet stock having a relatively broadfront plate folded at one end to form a hook,V a hooh-closing tongue plate 'pivotally supported intermediate its ends at a pointspaced from said front plate,'said tongue having a portion4 extendingforwardly of its pivot point to close saidV hook and having an operating portion eX- tending to the rear of said .pivot point, and a presser member on said rearwardly-extending portion in position to'be manually engaged from the front of the hook to operate the tongue to open thev hooln v 2. A bracelet hook formed of sheet stock having an outer body plate folded to form a hoch at one end, a tongue, means for pivot ally mounting said tongue in said body, said tongue having a hook-closing portion on one :side of the pivot-al point and a presser member on the opposite side of said pivotal point extending through said body plate for moving said tongue to open position by manual pressure.

A bracelet hook formed of sheet stock having an outer body plate folded at one end to form a hook, an inner body plate spaced from the outer plate, a spring pressed tongue pivot'ally mounted between said plates hai/4 ing a hook closing portion on one side of the pivot and a presser member on the opposite side of the pivot point, said presser member being formed integralwith said tongue and extending at `substantially a right angle therefrom through anopening in said outer body plate forl moving said tongue to open position by manual pressure.

a. A bracelet hook having 'a hollow body portion with a front plate formed of sheet stock hook-shaped at one end', a pivot pintle in said body, a spring pressed tongue in said body having pintle engaging members in'- te'rmediate itsends, a portion of said tongue on one side of said.l pivot being arranged to swing and close said front plate for swing- Y ing the closure portion to open. position.

5.- A bracelet hookv formed of sheet metal having, a hollow body portion witha hook at one end, pivot supportingears being formed within the body from one ofY its walls, a

pivot insaid ears a tongue supported intermediate its `length on said pivot and having a portiony in'onerside of the pvot 'arranged' to close said.Y h oolr and a portionon the opposite side of the pivot arranged to extend through the front ofthe body to be engaged and pressed inwardly to swing open. the hook-closing` portion, and al spring for returning said closure portion.

In' testimony whereof I aix my signature. l
