A. R. LO CURTO WATCH STRAP Filed Dec. 8, 1944 Patented Apr. 2, 1946 UNITED STATES PATENT OFFICE MZ'ZL alimony R. Lo Curto, Brooklyn, N. Y. Application December 8, 1944, Serial No. 587,139 1 Claim. 01. 224-4) The wrist watch cases in general use have, at their sides, two pairs of lugs or outstanding arms which are provided adjacent their outer extremities with aligned openings. The pair of aligned openings at each side or the watch case are adapted to receive a pin. Each pin may be inserted through a stitched loop at the end of the watch strap. In some cases the pins are sprung into the aligned openings, and in other cases the pin is made up telescopically, with a spring holding the two members of the telescopical pin extended when the pin is held by one pair of the watch case arms.

It frequently happens that one 01 the pins will become dislodged from its aligned openings of the watch case arms, so that the watch is not held upon the wearer's wrist by the normal holding means of buckle or clasp, and the watch drops and is lost.

Many devices have been proposed for preventing th dislodgement of the watch case and strap after a strap pin has pulled away from the watch case arms. As an example a leather piece has been stitched to the two sections 01' the strap so as to underlie the watch case and rest directly upon the wearer's wrist. While such means is effective, it has been found undesirable.

The specific object of my invention is to provide simple and eflective means for insuring the continued connection of a watch strap, with the watch case and watch held therebypupon the wrist of the wearer, notwithstanding the pulling away of one of the watch case pins.

My device will be described with reference to the accompanying drawing. in which I Fig. iii: a plan view showing an embodiment of the invention, a watch being held by the strap, the view being taken from the outer face or the watch. 7

Fig. 2 is a plan view, the strap sections being partly broken away and showing the under-face oi the structure.

Fig. 3 is a view similar to Fig.2, with the watch case removed.

Referring to the drawing I have shown at I a watch case having at each side two outwardly extending arms 2. Each pair or arms will have aligned apertures at 3, Fig. 1, to receive a pin 4. At 8, Is, I have shown two strap sections, one section having a buckle 8 to receive the other strap section which is formed with a row or apertures for coaction with the buckle.

The inner ends 01' each stra section are looped or otherwise formed to provide sleeves at 6 to receive one of the pins. In the present embodiment each watch strap section, at I, is provided with a separation.

second sleeve to receive my special safety device.

The latter consists of a flexible strand 8 passed through both or thesesleeves I, and its ends connected. at the rear faces 01 the strap sections. This strand may be of any strong and yieldable material, such, for example, as braided cord, silver or other metallic wire, or even narrow tape. My safety device may have its lengths at the rear face 01' the watch case crossed, as in Figs. 2 and 3, but this is not at all essenti The advantage 01' my safety device is that it adds no bulk or weight 01' any consequence to the watch and strap structure, it is yielding and entirely tolerable to the wearer, it involves very little cost, and itafiords adequate protection.

For clarity. oi illustration I have shown my flexible member I as a cord tied at'its ends, but it will be understood that whateverthe form 01. the flexible member 8 may be, i. e. tape, ribbon, braidbe in the form of a safety catch, or a socket and internally threaded retaining member at one end to coact with a threaded pin carried by the other end, etc. In short, the ends of the flexible member may be connected by a simple tie, or by me- I chanical means. as desired.

Having described my invention, what I claim and desire to secure by Letters Patent is as follows:

A watch strap consisting of two elongated sec tions held in spaced relationship, means at the free ends of the sections for fastening them tosether, such means permitting unfastening, a pair of loops carried by the inner ends of the strap sections and adapted to receive removable pins carried by the watch case, a second pair of loops carried by each strap section adjacent to the first pair of loops, and a continuous flexible strand threaded reversely through the second pair of loops so as to prese'nt a cross formation intermediate said two pairs of loops, said strand having its ends connected and thereby being adapted to securely restrain the strap sections against ANTHONY R. no CURTO.
