SIGNAL DEVICE.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed August 7, 1918.- Serial No. 248,710.

- citizen of the United States, and resident of the city, county, and State of New York, and ALLEN L. HAMLIN, a citizen of the United States, and resident of East Orange, Essex county, New Jersey, have invented certain new and useful Improvements in Signal Devices, of which the following is a specification.

This invention relates to a signal device and more particularly to a manual device which is adapted to be attached to the hand or the wrist of the operator and is more esplppially designed for military use insigna l.

Th5 object of the invention is to produce a simple and eflicient device of the class de scribed which may be worn without inconvenience to the operator and without interfering with the use of the hand.

In carrying out the invention we provide a support which may be preferably secured around the wrist of the operator and which is providedr'with an extension carrying a luminous disk at its outer end so that the same is positioned in thepalm of the hand. The manner of using the same and its operation and detail construction and the novel features thereof will be more fully described hereinafter. and defined and pointed out in the claims.

In the drawings accompanying this application we have illustrated a preferred embodiment of our invention, together with the details of construction and arrangement of the several parts. In the drawings like parts in the several views have been given the same reference numerals.

Figure 1 is a side elevation of the device.

Fig. 2 is a plan view and Fig. -3 an end view of the device shown in Fig. 1.

Figs. 4; and 5 are enlarged detail views,

partly in section.

The support 1 is arranged to encircle the wrist of the operator and is preferably constructed of a resilient material, such as spring-brass, which enables it to be readily slipped around the wrist and held securely in place. Of course, it will be understood that a strap or other suitable means may be employed if desired.

The extension or arm 2 is pivotally attached to the support 1 and carries a disk 3 at its outer end which contains a luminous material, such as radium paste, which may.

be held therein by means of a facet setting or otherwise, as may be desired.

The extension or arm 2 is curved or formed to extend from the wrist support It has been found that while different hands are difi'erent in size and shape that the portion or part, as well as the curvature, where the fleshy portion of the thumb joins the palm is approximately the same and this fact enables us to so form the extension2 as to always position the disk 3 in the center of the palm. To cause the disk 3 to lie close to the hand should the latter'be bent slightly back in signalin the end of the extension 2 which carries t e disk projects a substantial distance across the projected area' of the band 1, as shown in Fig. 3. p

The disk 3 is pivotally hinged at the end of the arm 2 so that the same may be sprung around the pivot either to present its luminous face 4 outwardly away from the palm or turned inwardly against the palm so that the luminous face 4 is concealed and not exposed.

The pivotal attachment of the disk 3 may be formed by cutting and bending outwardly portions such as 5 and 6, as shown in Figs. 4 and 5. The end of the arm 2 is bent around to form a bearing, as shown at 7 and 7 and a pin 8 is passed through the extensions 5 and 6 and the bent-over portions 7 and 7 which bent-over portions may extend into the openings in the disk 3 formed by bending the ortions 5 and 6, shown in Figs. 4 and 5. 'lhis permits of a very compact construction and allows the disk 3 to lie substantially flat against the palm of the hand.

turned out as described and may be succes-.

sively covered and uncovered by closing and opening the fingers of the hand over the same and, when used in the dark, will cause successive flashes of light and thus enable the same to be used for transmitting signals or messages by the dot and dash code, or otherwise, as will be readily understood.

When not in use the disk 3 may be turned with its luminous face toward the palm of the hand, in which position no light is visible and, as the disk and its support he close to the palm of the hand, the support or extension 2 following the curve of the fleshy part of the thumb where it joins the palm, the use of the hand is not interfered with.

When a spring supportis used, such as shown at 1, it will be noted that the opening between the ends 9 and 10 (Fig. 3) is at one side of the center line of'the support. This is to position the ends 9 and 10 on either side of the protruding bone in the wrist, which not only causes the support to lie close to the wrist but also prevents it from turning.

It will thus be seen that a very simple device is provided which lends itself to many uses but as many changes could be made in the details of construction and many apparently widely different embodiments of our invention designed without departing from the scope thereof We intend that all the matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative merely of an operative embodiment of our invention and not in a limiting sense. 1

IV hat we claim and desire to secure by Letters Patent is 1. In a signal device, in combination, a

support adapted to be attached to the wristof the operator, an extension attached to said support and projecting to a point to position the end thereof in the palm of the operators hand when the support is in position upon the wrist of the operator, and a luminous member carried by the end of said extension.

2. In a signal device, in combination, a support adapted to be attached to the wrist of the operator, a resilient extension attached to said support and projecting to a point to position the end thereof in the palm of the operators hand when the support is in position upon'the wrist of the operator, and a-luminous member carried by the said extension.

3. In a signal device, in combination, a support adapted to be attached to the wrist ofthe operator,-an extension pivotall attached to said support, and a luminous member carried by said extension and posi tioned in the palm of the hand of the op erator.

4. In a signal device, in combination, a support adapted to be attached to the wrist of the operator, an' extension attached to said support and curved in conformance to the curve of the fleshy part of the hand at the point where the thumb joins the palm of the hand and extending to the center of the palm, a luminous member carried by said extension and positioned in the palm of the hand of the operator.

5. In a signal device, in combination, a resilient band forming a support having an opening between its ends at one side of the center line adapted to be positioned around the wrist of the operator with said ends positioned on either side of the protruding bone of the wrist, and an extension attached to said support, and a luminous member carried by said extension and positioned in the palm of the hand of the operator.

6. In a signal device, in combination, a support adapted to be attached to the wrist of the operator, an extension attached to said support, and a luminous member hinged at the outer end of said extension and positioned in the palm of the hand of the operator and adapted to be swung around its hinge to conceal or expose the luminous portion.

7. In a signal device, in combination, a band adapted to encircle the wrist of the op erator, a resilient metallic arm secured at one end thereto and projecting in a general direction at right angles thereto, said arm being bent first outwardly and then inwardly for a substantial distance across the projected area of said wrist band, for the purpose set forth.

Signed at the city, county and State of New York, this 2d day of Aug, 1918.
