Patented June 9, 1931 PATENT OFFICE JULIO MOB-ALIS, F BROOKLYN, NEW YORK ELECTRIC LAMP Application filed June 28, 1929. Serial No. 374,534.

This invention relates to electric lamps.

It is among the objects of the present invention to provide a novel and improved electric lamp or flashlight which includes a generator for supplying electrical energy to an electric bulb therein.

A further object of the present invention is to provide a self-contained electric lamp with a generator and fluid means for operating the generator.

A further object of the present invention is to provide a device of the character described including a spring-pressed plunger adapted to urge fluid pressure to a suitable energy transfer mechanism for the generation of electrical current-for the lamp of the device.

A further object of the present invention is to provide an electric lamp including a cas- 29 ing forming a fluid pressure cylinder and a piston within said casing adapted to urge fluid from the cylinder to an energy transfer mechanism, together with a spring for urging the piston in the cylinder and means for releasing the spring.

Other objects of the present invention include the combination and interrelation of parts whereby the whole forms a simple, novel and improved device well adapted to the demands of economic manufacture.

Numerous other objects and features of the present invention will be apparent from a consideration of the following specification taken in conjunction with the accompanying drawings, inwhich Figure 1 is a longitudinal section taken through one embodiment of the present in vention and showing the piston in fully forward position;

Il ig. 4 is a sectional view talreu on lines '14 of Fig. 1, and r Fig. 5 is a sectional view taken on lmes 0 5-5 of Fig. 1. a

Referring more particularly to the drawmgs, the invention is disclosed as including an external casing 10, which is of the conventional self-contained electric lamp design. The casing 10 at its forward end is associated with a preferably separate generator casing 11, the front end of which is provided with a lamp assembly 12. The lamp assembly 12 includes the conventional lens 13 and electric lamp 14 which is supported through a reflector 15. i

The generator casing includes a central enlarged ortion 16, and an annularly extendmg re uced portion 17, which portion recelves therein the intermediate portions 18 of the pole pieces of an electric generator. The generator further includes an armature 19 which lies between the extremities or poles 20 of the pole pieces. The armature '19 includes the usual central shaft 21, the forward end of which is provided within the portion 16 with a commutator 22, over which brushes 23 are adapted to ride to conduct the electrical energy generated by the generator from the armature or rotor to the lamp 14. One of the brushes 23 is grounded to the easing 11 and therethrough to the assemblyl2, whereby the circuit therefrom may be completed through the reflector 15 to the base of the lamp 1 1. The other brush 23 is mounted upon an insulated conductor 24 which extends through the casing 11 and contacts with the central contact point of the base of the lamp 14. v

For revolving the armature 19, the shaft 21 extends rearwardly through the casing 11 and terminates in a rotor pf an energy transfer mechanism here shown in the form of a turbine, the rotor 25 of which carries suitable blades which pass undera valved discharge nozzle 26 whereby fluid passing through the nozzle will strike the blades and rotate the rotor 25, thus operating the generator to supply electrical current to the lamp 1 1. In connection with the invention. it will be understood that the invention is in no wise confined to the specific energy transfer mechanism herein shown and that, if desired, any equivalent means for rotating the armature 19in response to the flow of fluid may be utilized, such as the conventional fluid motor in place of the turbine here shown.

The casing 10 which forms the handle of the device, has provided therein a cylinder 27 of smaller diameter than that of the casing 10, whereby the walls of the cylinder are spaced from the walls of the casing 10. The cylinder 27 further terminates in a front wall 28, which is spaced from the rear wall of the casing 11, thus providing the desired space for the energy transfer mechanism therebetween. The nozzle 26 is mounted upon the front wall 28 and communicates therethrou h with the cylinder, whereby fluid from t e cylinder ma be forced through the nozzle against the tur ine wall. The rear of the cylinder 27 is provided with apertures 29, whereby the passage 30 formed between the cylinder 27 and the casing 10 communicates at its rear end with the cylinder 27, the front end of the passage being opened to the energy transfer chamber. Thus the fluid discharged through the nozzle 26 may, after operating the rotor 25, return to the cylinder through the apertures 29.

For forcing the fluid from the cylinder through the nozzle 26, the cylinder is provided with a valve piston 31,thehead of which is apertured as at 32 and inwardly flanged as at 33, to co-operate with a longitudinally movable valve 34, which is mounted upon a longitudinally extending pin 35, the forward end of which extends through a brace 36 of the piston head. The valve 34 is associated with a coil spring 37, which extends longitudinally within the cylinder, its rearward end abutting the end wall 38 of the cylinder. The arrangement is such that with the spring 37 released, pressure is exerted on the valve 34 which moves longitudinally to close as in the position shown in Fig. 3, and which when closed forces forwardly the piston 31, thus discharging fluid through the nozzle 26 and operating the transfer mechanism to energize the lamp 14. When the spring 37 is rewound, the forward end of the spring by its attachment to the valve 34, moves the valve rearwardly to the position shown in Figs. 1 and 2, and, therefore, further rearward movement of the spring moves the piston 31 rearwardly. The valve during such movement is retained open so that the fluid behind the piston may pass forwardly through the piston. The valve of the nozzle 26 is such that communication between the energy transfer chamber and the cylinder is cut off by such rearward movement and flow from the cylinder to the energy transfer chamber only is permitted.

For contracting the spring 27 and rearwardly moving the piston, the rear wall 38 of the cylinder is provided with an inwardly extending sleeve 39 about which the spring may be coiled, as shown in Fig. 2. Within the sleeve 39 a rotatable inwardly extending latch-controlling sleeve 40 is provided which is provided with a pair of parallel elongated apertures '41 and with dependin ears 42, through which the pintle 43 of a atch 44 is mounted.

For pivotally moving the latch 44 and rotating the same with the sleeve 40, a rotatably and reciprocatively mounted plunger 45 is provided, its forward-end being received within the sleeve 40 and including a cross arm 46 which extends through the aperture 41 of the sleeve 40. The rearward end of the plunger 45 terminates in a square extremity 47, which is mounted within an operating sleeve 48, which is carried by the outer casing 10 and which may be rotated and reciprocated with respect thereto. The latch 44 is bifurcated, thus including the depending arms 50, through which the pintle 43 passes. Adjacent the pintle 43, the arms 50 are enlarged to provide a projection 51, which is adapted to be engaged by the cross arm 46 which controls the pivotal movement of the latch 50.

It will be understood that the invention is not specifically confined to the spring release mechanism and that, if desired, the spring may be immediately released after being wound up, thus putting the fluid under pressure, and the valve may be controlled exteriorly by suitable mechanism, thus controlling the release of the fluid through the turbine where it may energize the transfer mech anism with a minimum loss of time. In such an arrangement, the device will be more easily operated and the parts 52 and 53 may be arranged at all times in leak-proof relation.

In the operation of the device, assuming the spring to be in a fully expanded position, as shown in Fig. 1, and the operating fluid to be behind the piston 31, the sleeve 40 is rotated in a clockwise direction as shown by the arrow in Fig. 4. By such rotation with the plunger 46 being in rearward extending position, the latch 44is maintained transverse- 1y of the cylinder and rotates, thus forcing the spring rearwardly into the coiled position shown in Fig. 2. Such movement of the spring rearwardly moves the valve 34 thus opening the valve and permitting the fluid behind the piston to pass to the forward portion of the piston and permitting the piston to freely move rearwardly. The rearward movement of the piston will, however, not cause a passage of fluid from the energy transfer chamber to the cylinder due to the suitable ball valve or equivalent in the nozzle 26L WVhen the spring is substantially all coiled about the sleeve 39, as indicated in Fig. 2, the device is ready for operation, the fluid being within the cylinder in front of the pis ton. The spring, however, is retained against expansion by the latch 44 which is retained in the transverse position by the cross arm 46 the sleeve 48 is moved inwardly and may be engaged in this inner position by the engage ment of external threads of an inwardly extending flange 52 with the internal threads 53 of the rear recess of the cylinder 39. The inner movement of the plunger 45 moves forwardly the cross arm 46 in the apertures 41 of the sleeve 40. Such movement of the cross arm 46 will permit the latch 44 to move forwardly about its pintle 43, thus releasing the spring 37 as indicated in Fig. 3, whereby the spring will ex and and will force the valve 34 against the ange 33, thus closing the valve and, at the same time, moving forwardly the piston 31, whereby the fluid will be forced from the cylinder through the nozzle 26 against the rotor 25 to rotate the same and energize the lamp 14. The fluid, after such transfer of energy, passes rearwardly through the passage 30 and through the apertures 29 to the rear of the piston 31. At the expira: tion of such expansion of the spring the device will again be in the position shown in %rom the foregoing it will readily be seen that the invention provides novel, simple, and improved structure, forming a self-contained battery-less hand lamp. It will be understood that the fluid used, the energy transfer.

mechanism and the general design and construction of the apparatus, are sub ect to the choice of the constructingnengineer and that the invention is not con ed to the specific details of such matters herein disclosed and that numerous changes and modifications and the full use of equivalents may be resorted to without-departing from the spirit or scope of the present invention as outlined in the appended claims.
