HAND S IGNAL LIGHT Filed Feb. 9, 1925 fiervuzrd (arosell Her-man G. .ssman Patented June 17, 1930 UNITED STATES PATIENT OFFICE BERNARn-oARosELLI AND HERMAN e. ESSMAN, or NEW YORK, N. in; SAID OAROSELLI I ASSIGNOR TO SAID ESSMAN HAND SIGNAL LIGHT Application filed February This invention relates generally to a handoperated signal lamp. It has for its ob ect a lamp which may be attached to the wrist of the operator and is to be operated by the movements of the hand or wrist of the operator. The lamp disclosed in this application and described hereinafter has special application to manual signaling by automobile drivers, or to traflic signaling by trafiic officers. There are many other applications of the present invention which will become obvious from the disclosure and description which appear hereinafter.

Fig. 5 is a face view of the invention with a portion of the cover of the casing removed.
In this view the device is shown with the lamp illuminated;
Fig. 6 is a view similar to Fig. 5 but with the lens removed and with the lamp unilluminated;
Fig. 7 is a bottom view of the device;
Fig. 8 shows another modification of the invention.
The casing of the device consists of the body 10 and the cover 11. The body 10 which is stamped out of an integral piece of material comprises an oblong portion 12 and a circular portion 13, the two portions being connected by a constricted neck 14. The circular portion 13 is provided with slots 15 and 16 on its periphery. The back face portion of the casing 10 is provided with two strips 17 integral with the other portions of the casing. The strap 18 passes through the strips 17 and is provided with a buckle 19 designed for the purpose of attaching the device to the wrist of the operator.
The coverll is shaped in a manner to conform to the shape of the body of the casing. Its circular portion 20 is provided with a circular aperture 21. The body of the cas- 9, 1925. serial No. 8,011.
the cover 11 is also provided with two projections 26 which facilitate the removal of the cover from the body of the casing.
A body of insulating material 27 is lodged in the constricted portion of the body of the casing. An electric socket 28 is lodged in the body of the insulating material 27 The socket is adapted to receive the signal lamp 29. Spring contacts 30 and 31 are attached to the center contact and shell contact respectively of the socket 28. I,
A lens of transparent material, such as mica, or the like, 32, is placed in the manner shown in Figs. 1 and 4, so as to cover the circular aperture 21 and also the slots 15 and 16. This lens is held in position by the cover 11. The lens may be provided with a red or any other colored portion 33.
An electric cell 34, having terminals 35 and 36 substantially smaller in size than the dimensions of the oblong portion 12 of the casing 10, is disposed in the oblong portion 12 of the casing 10. The cell 34 is placed in a mounting 37 which consists of a substantially I oblong portion 38 and lugs 39, 40, 41 and 42 projecting upwardly therefrom. These lugs serve to grip the cell and hold the cell attached to the mounting 37 The oblong portion 38 of the mounting also has a portlon 43 which projectsbeyond the confines of the cell and in a direction coplaner with the oblong portion 38. This portion 43 is provided with an aperture 44 which co-operates with the pin 45 which is attached to the inner face of the casing 10. By the aid of the. mounting the battery is given a free sliding motion within the casing and with relation to the walls of the casing.
In order to prevent the possibility of the discharge of the cell when the lamp is not in use, a safety device is provided which maintains the cell in such a position that the electric socket is not in electrical connection with the cell. This safety device consists of a bar '50 which passes through slots 51 and 52 in the edges of the cover 11. The bar is provided with downwardly projecting lugs Y 55 presses against the side of the cell and hblds it immovably in such a position that no arring or any movement of the device will close the circuit between the contacts 35 and 36 and 30 and 31, respectively. Any possibility of the unnecessary discharge of the cell is thereby prevented. When it is desired to put the device in operation it is strapped on the operators wrist by means of the strap and buckle 18 and 19, and the safety bar is moved to the position shown in Fig. 5. It will be seen that the cell with its mounting may now be moved from the position shown in Fig. 6 to that shown in Fig. 5, in which the contacts 35 and 36 are in electrical connection with the socket contacts 30 and 31, re spectively. The mounting 37 which is disposed between the cell and the inner face of a the casing reduces the friction between the cell and the casing and permits ready oscillation of the cell and mounting about the pivot pin 45. Assuming that the device is to be used by a vehicle operator, such as an automobile orthe like, the safety bar 50 is left in the position shown in Fig. 5, while the cell 1 and its mounting 37 are normally in the position shown in Fig. 6. When the operator wishes to signal he moves his arm outwardly with the result that the cell and its mounting are moved by gravity into the position shown in Fig. 5, whereby the lamp is illuminated.
In the device as shown and described hereinabov'e the illumination of the lamp is effected by a movement of the arm to the left Fig. 8 shows a modification of the invention which may be operated on an upward movement of the hand. This modification is substantially identical with that shown in the other figures in the drawing, but differs from them only in the following respects: The cell is disposed in such manner that its terminals 61 and 62 point downward. A contact 63 which is attached to the shell contacts of the socket 64 is in electrical contact with the casing 10. An insulated. wire 65 is attached to the center contact of the socket and is disposed along the side of the casing and placed near the bottom of the casing. Its bared end 66 is disposed in such a manner that when the arm of the operator is raised upward the contact 62 of'the cell will establish electrical connection with the wire 66 andthereby complete the circuit for the si nal lamp.
This device may also be used y ushers in theatres or by any person who wishes to temporarily illuminate any spot intermittently and still have his hands free for other purposes.
