SIGNAL LAMP.

Application filed November 20, 1928. Serial No. 675,901.

To all whom it 'IIldIl/OOILCGWl-f Be it known that I, MARTIN M. CUNNINe-- HAM', a citizen of the United States, and a resident of Far Rockaway, borough of- .signaling lamp's which are especially designed for use by.tra fiic oflicers or drlvers of vehicles.

The broad object of the present invention is to provide a hand signalingla-mp which is adapted to be associated with the Wrist and hand of the user whereby the same may i be conveniently emploiyied for the purpose of giving signals in tra More specifically the invention contemplates a hand signaling lamp provided with a switch for controlling the energizing of the lamp, which switch is automatically operable upon movement of the hand or arm to si aling position for closing the circuit to said lamp.

The invention furthermore contemplates a palm lamp, the casing of which is so'constructed as to snugly fit the wrist and contour of the palm of the hand in order that the interference of the same with the use of the hand is reduced to an absolute minimum..

'As a still further object the invention contemplates a hand signaling lamp of the character set forth which is comparatively simple in its construction, inexpensive to manufacture and produce and wh1ch is thoroughly reliable and highly eflicient in its purpose. 7

With the above recited and other objects in view, the invention resides in the novel construction set forth in the following speci fication, articularly pointed out in the appended c aim and lllustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claim is ex- Fig. 2' is a side view with parts in section illustrating the connection between the conduit-wires and the batter Fi 3 is a sectional view taken approximate y on the line 3--3 of Fig. 2.

Fig. 4 is a sectional view taken approximately on the line 4-4 of Fig. 2.

Fi 5 is a face view of a modified form of signa lamp in applied position on the back of the hand.

Fig. 6 is a side view thereof.

Referring to the drawings by characters of reference and rticularly to theconstruction illustrate in Figs. 1 to 4 inclusive, the hand signaling palm lamp is illustrated which consists of a housing or casing 10 the external surface of the rear wall 11 of which is shaped to closely conform to and fit the wrist and palm of the hand. The upper terminal 12 of the casing drical formation and is provlded with a transparent panel 13 constituting the front wall to allow the rays from the lamp bulb 14 to be visualized therethrough. The lamp bulb is supported in a suitable socket 15' in the terminal 12 and is connected by circuit wires 16 and 17 to the spaced contacts 18 and 19 carried by an insulating strip 20 is of cylintion on the wrist and hand. .A s iding circuit closing element 24: is inounted in the terminal 21 and is provided with a reduced boss .25 which protrudes throu h a guide slot 26 in the coverlng plate 27. T e circuit closing element 24 is provided with contact members 28 and 29 which are connected with terminal posts 30 and 31 projecting upwardly through the boss 25. A spring 36 normally functions to move the circuit closing element 24 to a position to dispose the contact members 28 and 29 out of engagement with the contacts 18 and 19. The terminal posts 30 and 31 are connected to the terminals of the conduit wires 37 which are insulated and inte'rtwisted and lead to the pole terminals 38 and 39 of a pocket battery 40. A coiled contractile spring 41 is secured and their connection with the pole terminals 38 and 39. Normally when the arm A of the .user is in a non-signalin position a sufiicient slack is produced in the ength of the circuit wires 37 to allow the spring 36 to function to shift the circuit closing element 24 to a position inwhich the contact members 28 suflicient pull is exerted on the circuit wires 37 to move the circuit closing element 24 against the actionvof the spring 36 whereby the contact members 28 and 29 engage the contacts 18 and 19 for closing the circuit and energizing the lamp bulb 14. By shaping the rear wall 11 of the casing-or housing 10 to conform to the wrist and palm of the hand, it will be noted that the device is comfortably mounted in a convenient position for signaling purposes and reduces the interference of the same with the use of the hand, to an absolute minimum.

In the modified adaptation of the invention illustrated in Figs. 5 and 6 the construction is identical with that of the preferred embodiment with the exception that the casing 10 and the rear wall 11' thereof are on a straight line for fitting the same to the wrist and back of the hand whereby the de- 80 of peripheral side transparent paneled open- 86.

ings 12 which may also be pro vided in the terminal 12 of the first form and which panels are designed for the purpose of allowing for the passage of the light rays from the lamp when illuminated whereby the hand '03 of the user will be flooded with light. I claim v A palm lamp for iving hand signals comprising an elongate housing, the said housing being shaped to fit the contour of the 45 wrist and the palm of thc hand, a switch in'the-housing, the said switch located in that end of the housing which fits the wrist, a'windowed compartment in that end of the housing which fits the palm, a lamp in the said windowed compartment, and means for fastening the housing to the wrist.

MARTIN M. CUNNINGHAM.
