MAGNETO FLASH LIGHT.

Application filed May 1, 1922. Serial No. 557,592.

To all whom it may concern:

Be it known that I, ANTOINE LUZY, a citizen of the French Republic, residing 34 Rue Sorbier, Paris, France, have invented new and useful Improvements in Magneto Flash Lights, of which the following is the specification.

The present invention relates to a device for miners electric lamp and other applications, in which the light is obtained by means of an electro-magnetic generator forming a part of the mechanism of the lamp.

This device is characterized in that it can give a lighting of long duration and, although its principle is applicable to portable lighting apparatuses of very varying dimensions, the present lamp device cannot in any way be assimilable to electro-mechanical lamps of very small dimensions, commonly designated under the name of pocket lamps.

In this device are combined:

1. A generator of electricity ofthe magneto type, with a permanent rotating bipolar or multipolar, monoblock or polyblock magnet;

2. A driving mechanism acting under the action. of a powerful spring or, generally speaking, of any device for accumulating mechanical energy.

This device allows of realizing various designs of lamps for domestic lighting and which may be placed on a table. By actuating these lamps by means of a weight, this device allows also of-realizing varied designs of wall lamps.

In the accompanying drawing is illu"- trated, by way of example, a form of carrying out the invention:

Fig. 1' is an elevation of this device. Fig. 2 is a vertical and cross section thereof.

Near the metallic frame 1 is placed the generator, of electricity suspended by a hanger 2 secured under the upper plate 4. The hanger 2 carries a cylindrical part 5 on which is mounted the armature 6. In the part 5 is provided a central hole in which the shaft '2 of the magnet 8. The shaft 7 is in relation through a flexible connection 9 with the shaft of the last pinion 10 of a speed multiplying mechanism. This flexible connection allows of not taking into account the alinement of the shafts 8 and 10, to render the magneto independent of the mechanism and to'ensure the easy fitting up and removal of the same.

The pinion 10 receives its movement from the rack 12, through the medium of the pinion 13, wheel 14, pinion 15, wheel 16, pinion 17 and finally of the wheel 18. The rack 12 is itself'driven by the spring 19 and the pinion 13 transmits the movement from the rack to the wheel 14 through the ratchet 20 which acts on the pawl 21.

The spring 19 being very powerful requires in order to be stretched a high pressure stress. For stretching this spring, the detachable lever 22 is pressed down, this lever actuates the socket 23 carrying the pawl 24 pressed by the spring 25.. The pawl actuates the ratchet 26 carried by the shaft 27 on which is rigidly secured the pinion 28 which controls the pinion 29 carried by the shaft 30. The pinion 29 engages with the rack 12 which is provided with teeth on its two opposite faces.

For the system of winding the spring through a lever, might be substituted any suitable winding system, either through a screw or otherwise and the spring might have any shape whatever, either a spiral, spiral conical or other shape.

During the time the spring 19 is stretched,

the rack moves down, the multiplying mech- '26 and the pinions 28 and 29 can rotate freely under the action of the rack which again'moves upward. The pawl 24 may be released from the ratchet by any other suit able method. The bearings 33 and 34 support the spring winding mechanism.

The spring 19 is guided by small columns 35 and is held between the lower plate integral with these small columns and the guide plate 38 secured at the lower end of the rack.

When the spring slackens, the magnet 8 rotates and the current generated in the armature 3 is conveyed to the lamp 3'? through the connections 3 one of which may be in lift pass into the interior body connection with the apparatus or through any suitable system of connections.

As in all miners lamps, the lamp 37 is protected by any suitable means, comprising or not a glass globe 38 and a covering plate carrying the suspension ring 39.

The present device may be completed by any suitable stopping and starting system so that the operation f the lamp may be interrupted at will, although the spring is stretched. The present device may also be provided with a regulating system adapted to regulate the speed of the said device and to maintain constant the electromotive force. I

When .the socket 23 is raised so as to of the casing 40, a bolt 23' pivoted on the casing around an axis formed by the shank of a screw 23", folds over so as to retain said socket in the position shown in dotted lines on Figure 1 of the drawings.

This device is finally enclosed in a casing 40 the shape and dimensions of which are designed in view of the use to which the lamp is to be put.

The advantages of the present, invention clearly appear if it is considered that the miners lamps actually employed, whatever may be the system of the same, necessitate for their maintenance complicated and costly means and for their use charges of 011, petroleum or electricity the cost price of which becomes at length very high. These inconveniences do not exist with the device which has just been described the life of which is very long, the maintenance practically null and the charging free since it is supplied by the miner himself by means of his muscular energy.
