Feb 119 1924. EAMMQB R. HARGOT PORTABLE LIGHT Filed Jan. 5, 1922 a ii iii 1. Hz/ 26" u INVENTOR ATTO RN EY Patented Feb. 19, 1924.



Application filed January 3, 1922. Serial No. 526,791.

To all whom it may concern:

Be it known that I, Ram: HAneor, a citizen of Belgium, Europe, residing at Chicago, in theconnty of Cook and State of Illinois, have invented new and useful Imrovementsin Portable Lights, of which the ollowing is a specification.

This invention relates to electric lamps, and comprehends the construction embodying no a magneto .for generating the current of lighting the lamp, the invention residing in the construction, combination and arrangement of parts as claimed. In the drawings forming part of this ap- Ilt plication, like numerals of reference indicate similar parts in the several views, and where'- Figure 1 is a vertical sectional view throu h the lamp constructed in accordance with invention.

Figure 2 is a fragmentary view'showing the manner of winding the spring motor.

Figure 3, is a top plan view. Referring to the drawings in detail, W indicates a lamp casing which may be. of

an suitable size or configuration, and divi ed by partitions 11 into a magneto compartment 12, a motor compartment 13, and a lamp compartment 14. An electric light bulb 15 is arranged in the compartment 14 as is also a reflector 16. This compartment is also equipped with suitable lens 17. If

desired, an electric light bulb 18 may be arranged at one side of the casing and suitably'connected in circuit by a switch so that either of the electric light bulbs may be illuminated. Arranged in the compartment 12 is a magneto 20 which includes a shaft 21, which projects through the'adjacent pan titioii 11 into the compartment 13, the shaft being driven by a sprin motor 22 through the instrum'entality of t e train of gearing illustrated. The motor shaft 24 is equipped with a ear 25 which meshes with a pinion in 26 carried by the shaft 27 and associated with this shaft is another gear 28 which meshes with a pinion 29 supported on the shaft 30. Also associated with the shaft 30 is a gear 31 which meshes with a pinion 32 carried b the upper end of the motor shaft 21. A audio or bail 34 is provided to facilitate carrying of the lamp, while a hook 35 is also provided for supporting the lamp 4 on a stationary object orsupport.

V In practice, the motor operates the magneto with the required speed through the train of gearing to generate current for the lighting of the lamp or lamps, so that the lamp may be-used l ndefinitely without the trouble of replacing dry batteries, which are usually employed in lamps of this c0nstructlon, and which soon become exhausted.

Arranged within the compartment 12 is a suitable brake 26 which when moved into active association with the magneto, prohiblts turning of the latter, this being desired while the motor is being rewound. The brake '26 is connected to one end of a cable 37 which is extended through a tubular member 38'arranged within the casing, the upper end of the cable being connected to a lever 39 which when actuated, pulls upon the cables, applies the brake in a man ner and for a purpose stated. Arranged adjacent the top of the casing is a lever 40 fulcrumed as at 41 on a suitable bracket 42, and this lever is also connected through the instrumentality of a link 43 to a rack bar 44. A contractile spring 44' has one end secured to the rack bar 44 and its opposite end secured to a fixed element 45, and is adapted to return the rack bar to normal position. Meshing with the rack bar 44 is a pinion 45 arranged on one end of the shaft 46, the opposite end of the shaft supporting a bevelled gear 47 meshing with asimilar %ar 48 forming part of the spring motor. epending from the upper portion 11. there is a bracket 41 supporting a pawl 42' which is arranged to engage a ratchet wheel 43' fixed to the gear 48 as shown in Figure 1 of the drawings. The shaft 46 journaled in suitable hearings or brackets 49. The motor also includes a ratchet mechanism 46 which allows the motor to be Wound without transmitting motion to the magneto, and when the latter is released to operate the magneto for the purpose specified. When it is desired to wind the motor the brake 36 is applied as stated, and the lever 40 actuated. The ratchet mechanism 46' isconstructed to turn the shaft 46 when the rack bar 44 is depressed, or in other words moved downwardly when pressure is exerted upon the lever 40, but when the rack bar 44 is returned to its normal position. the ratchet-mechanism 46 idles, so that the rack bar 44 can move in one direction without imparting movement to the shaft 46.

Incident to the movement of the rack bar,

-When it is desired to wind the spring motor 7 the brake 26 is applied to the magneto 20 by operation of the lever 39. A reciprocator'y movement is then applied'to the lever 40, this movement being transmitted to the rack bar through the medium of the link 43, the rack bar will in turn rotate the bevel ear which rotation will be transmitted to i t e gear 48 and thence to thespring motor.

When the spring motor has been wound, the rack bar 44 is released through the medium of a clutch mechanism 46. The spring will then unwind and cause the magneto to revolve, after the shaft 46 has been released.

The magneto may also be operated from a source independently of the spring motor, and as illustrated in Figure 1, a flexible shaft 50 may be connected to the shaft of the magneto for this purpose. Interposed between tlfe gear 32 and the magneto there is a clutch 50 which releases the spring motor and prevents it from being wound when the shaft 50 is adapted to operate the mageto.

apparent, I desire to have it-understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of .what is claimed.

What I claim is: V

A portable light of the character described comprising a casing, lamps carried thereby a magneto arranged in the casing, caring connected with the magneto, a manually operable rack bar, a spring motor connected with the gearing and 'rack bar, a handle carried by the casing, a pair of pivoted levers carried by the handle, one of which being connected with the rack bar, a brake element operated by the remaining lever and arranged within the casing adapted to engage the magneto to render the same inoperative, and an operating rod connected with one of the levers and the brake element respectively.

In testimony whereof I aflix my signature.
