ISLAND.

CORPORATION OF RHODE BRACELET HOOK.

Application filed April 16. 1925. Serial No. 23,705.

This invention relates to an improved construction of bracelet hook employed primarily for attaching 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 hook closing member arranged to extend through the back of the hook into position to be engaged and lifted to open the hook to permit its ready detachment from the watch.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a view showing the back or the outer portion of the hook and showing the operating end of the hook-closing member.

Figure 2 is a perspective view of the hook body plate with the hook-closing member removed therefrom.

Figure 3 is a perspective view of the inner body plate of the hook detached from the outer body plate.

Figure 4 is a perspectlve view of the closure member detached and before being bent into knee lever shape.

Figure 5 is a detail of the spring which presses the hook closing member to closed position.

Figure 6 shows this hook-closing member as pivotally mounted on the inner body plate.

Figure 7 a longitudinal sectional elevation showing the hook-closing member as pivoted on the inner body plate.

Figure 8 is a section on line 88 of Fig ure 1.

It is found in the practical operation of ordinary bracelet hooks somewhat difliieult to release the same from the bail of a watch, and to permit this hook to be more readily detached from engagement with the watch bail, I have provided a knee lever type of hook-closing member which is pivotally mounted at one end having one arm extending across the mouth of the hook to close the same and the other arm extending up through the back of the hookinto position to be engaged to open the hook permitting it to be readily detached from the hail of the watch; and the following is a detailed desciption of the present embodiment of my invention showing one construction by which these advantageous results may be obobtained With reference to the drawings, 10 designates the body portion of my improved bracelet hook which is formed of sheet stock, one end of the outer plate of this body portion being folded to form a hook as at 11 and this plate is provided with an opening 12 for the purpose presently described This outer plate is provided with rearwardly folded side flanges 13 and an inner body plate 1 1 is provided with outturned flanges 15 which fit inside the flanges 13, the edges of the flanges 13 being rolled over the edges of this inner plate to lock the'two together. At the end 16 of this inner plate is left a space 17 for the entering mouth of the hook and at this end of the plate is formed a pair of fingers 18, each being rolled into pivot ears 19.

In order to form a hook-closingmember which may be operated from the outside of the body plate and be lifted so as to open the hook to permit its ready detachment from the hail of the watch or other device to which it is engaged, I have formed a knee lever member 20 which is preferably stamped from sheet stock formed first in the shape illustrated in Figure 4 having a transversely arranged integral pivot pin 21, the same being folded at 22 substantially at its middle portion providing an arm 23 which extends across to normally close the mouth 17 of the hook and an outwardly-extending arm 24 which projects through the opening 12 in the body of the hook and is provided with a forwardly extending thumb-engaging end 25 which overhangs the opening 26 in the body of the hook and may therefore be readily engaged by the thumb nail of the wearer and be readily lifted to open the mouth of the hook.

In order to cause this hook-closing memher to normally close the opening of the hook, I have provided a coiled spring 27, and mounted the coil upon the pivot pin 21 of the closure member, one end 28 of this spring resting upon the inner face of the inner body plate while its opposite end 29 extends through the notch30 of the closure member and engages the inner face thereof, by which arrangement the closure member normally stays closed to revent accidental disengagement of the hoe r from the-watch ll ll bail and this closure member may be "eadily raised to permit the hook to be detached when desired, the arm 2st assisting in guiding the engaged member from the hook.

My improved closurernernber is very simple and practical in construction, is eliiective in its operation and may be readily operated to release the hook Without being obliged to torce the linger around underneath the same to lift the closure member when the hook is in position on the arm of the wearer.

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

I claim l. A bracelet hook termed of sheet stock having an outer body plate folded to form a hook at one end, an inner body plate spaced therefrom, a spring pressed tongue pivoted at one end to said inner plate and positioned to have a portion close the month of the hook and a portion of said tongue to extend through "said outer plate to be engaged and swung; back to open the hook.

A bracelet hook formed of sheet metal. outer body portion folded into hook shape at one end and having an opening adjacent the hook, and a spring; pressed knee lever pivoted relative to the body and positioned to have one arm oi said lever extend forward to norn'ially close the hook opening, the other arm en'ending across the book through the opening in the body thereof to be engaged and svmng hack to open the hook and to as it in detacl'iingthe hook from an engaged member.

3. A. bracelet hook con'iprising a sheet metal lmdy portion having an outer plate with hook shaped end and an opening therethrongh adjacent the bend of the hook, an inner plate for said body portion, a knee lever l, r closing said hook, hinged at the end of one arm to said inner plate and having a portion extending; through said opening}; to provide a manually operating lin 'er :lor liltingsaid hook-closing member and a spring; actii'r ir on said lever tor holding it in hoomclosing; position.

4. A bracelet hook connorising a sheet metal body having; an outer hook-shaped plate with side wall along: the shank portion thereof and an inner plate attached there to, integral spaced pivot receiving eyes termed by folding: e:-:tensions at the end of said inner plate. a knee lever for closing said hool: having lateral extensions engaging an id eyes tor pivotally mounting said lever, an operating f nger extending: through said outer plate and attached to said lever, and a spring; for holding said lever in engagemeat with the hook of said plate.

In testimony whereof I aflix my signature.

CHARLES H. PATTEN.
