CUFF-FASTENER.

SPECIFICATION forming part of Letters Patent No. 397,119, dated February 5, 1889.

I Application filed November 16,1888. Serial No. 290,991. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY C. FRANK, of the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in Cuff Fasteners, of which the following is'a specification.

I have in a patent to me, dated November 22, 1887, No. 373,556, set forth a style of cufffastener provided with a spring-clasp taking hold of the edge of the opening in the sleeve above the wristband, and which engages with the cuff through the intervention of a hook, which is engaged in the nearest button-hole and connected to the clasp by a chain of sufficient length to hold the cuff in the proper position. It is found that the great freedom allowed by this loose connection is objectionable. It is found that in working with the left hand to fasten the cu ff on the right wrist, after the hook has been engaged with the cuff, the looseness of the connection makes it troublesome to get the clasp in the right position. The same difficulty, but to a less extent, obtains in adjusting the cuff on the left wrist. The rigidity of the hook in my former patent involves difficulties in engaging it with the cuff, and the rigid hook is not certain to retain its hold on the cuff while in use.

I have devised an improvementin which the hook is jointed, and the joint is provided with a spring which is arranged to act] ike the spring of apocket-knife to hold the hook either open or closed. In preparing to engage it with a cuff the hook is set open. bo soon as it is engaged it is closed,and the same spring serves to keep it closed and insure its retention in the cuff. The hook is extended in length to give the required distance between the clasp and the button-hole of the cuff, and is connected to the clasp by a swivel-joint which allows it to turn, butdoes not allow it any further liberty. Th is aids to hold the clasp in the proper position to be engaged with the shirtsleeve.

The accompanyin drawings form a part of this specification and represent what 1 consider the best means of carrying out the invention.

Figure 1 is a general perspective view showing the device in use. The remaining figures show the device detached on a larger scale. Fig. 2 is a face view, and Fig. 3 is a corresponding edge view. The .renntining figures show portions on a still larger scale. Fig-dis a longitudinal sect-ion showing the hook closed. Fig. 5 is a corresponding section showing the hook open. Fig. 6 is a corresponding face view. Fig. 7 is a. longitudinal section with the hook detached. Fig. 8 is a corresponding section showing a hiOtllflOfll'lOYl of the form of the hook.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

A is a portion of the shirt-sleeve, and B an ordinary cuff, having holes b, which. receive an ordinary cuff-button, (3. My fastener has a spring-clasp, G, composed of two parts with a connecting-rivet and actuating-spring, as 111 my former patent referred to. Instead of the extremely flexible connection before employed, this clasp is stiffly connected to the hook, with liberty simply to be rotated. This is effected by extending the rivet in the direction toward the hook and embracing the extended portion in a long sleeve formed on the hook.

E is a long shank of the hook, and F. a sleeve formed in the end and embracing the rivet g of the clasp G, as shown. A hinge, e, connects the shank E to a hook, D D D D \Vhen the device is engaged with a cuff and conditioned for use, the part D extends nearly or exactly in line w th the part E. The part 1) extends nearly at right angles to D, and the partD extends in the general direction toward the clasp G, curved as shown. A short arm, D, extends from the hinge e nearly in the plane of the shank E. This arm D is subject to the .force of a fiat spring, M, which is strongly and stit'tiy held on the inner face of the shank E by rivets E This spring M presses forcibly on the hinge e. \Vhen the hook is opened in the position shown in Fig. 5, the spring M holds it stifiiy open. In this position it may be easily thrust through the proper button-hole in the cuff. \Vhen this is effected, the wearer turns the hook on its pivot: c, and the short arm D, after deflectin g the spring M in its middle position, is acted on by the spring M, so as to snap the hook into the closed position, as in Fig. at. Thenceforward my device remains engaged with the cuff in the same manner as in my patent of 1887, but still more efleetlmlly, because the action, of the spring lll urges the curved arm 1.) into Contact with the face of M, and insures the continued engagementof the parts with the cult until the wearer shall again fm-cihly straighten the hook to facilitate its detaehment from the coil.

l\lio(fli1ieations may he made by any good mechanic without departing from the principles or sacrificing the advantages of the invention. I can vary the length of the projecting end of the rivet g, corres ionding'ly varying the length of the sleeve E, which einbraces it. It is only important that it he stiii. with regard to the length and easy to turn laterally, so as to allow a hook to serve for either the right or left eufl'. I (an vary the widths of all the parts.

Figs. 7 and 8 show modifications in the I prefer that shown in Figs -1 I claim as my invention- 1. In a cuff-fastener, the hinged hook D D I) I) and shank E, in combination with each other and with the spring M and clasp G, arrangedii'or joint operation as herein specified.

2. In a euli"-l.'astener, the swivel E, formed on arigid extension of the shank E, in combination with the hook I) D D 1) and with the spring-clasp G, the fastener being adapted to serve right or left at will, while holding itself rigid longitudinally, as herein specified.

In testimony whereof I have hereunto set my hand, at New York city, this 15th day of November, 1888, in the prescmce of two subserihi ng' witnesses.

IIENRY U. FRANK.
