tric Lights, of which the following is a specification, reference being hadtherein to the accompanying drawing.
My invention relates to portable electric lights and has forits object the production of a self-contained'unit in which shall be combined a motor, a generator, a lamp and a control device, without any battery In order to attain my object I mount a magneto generator of standard typ'e upon a suitable base, mount a mechanically driven train of gears and a lamp upon the magneto, and inolose the whole within a pressed metal casing provided with a bulls-eye over the lamp a on one side and a button for stopping and starting the clock-work on theother side.
My invention is illustrated in the accordpanying drawing in which- Figure 1 is a vertical longitudinal sectional view of my machine, showing the armature and connected parts in full lines. Fig. 2 is an end view with the casing partly broken away, showing the. side plate, lamp, and rotor bearing. Fig. 3' is an opposite end view showing the spring motor.
Referring to the drawings, I preferably employ a magneto. of standard commercial type,'that is to say with two or more horseshoe magnets having their polar ends provided with shoes having cylindrical oppos- 4 ing faces, between which a rotor revolves, and-in its revolutions shifts the magnetic fluxthrough the turns of a generating winding, which produces the desired current. In the present case, I have chosen to illustrate a magneto with an armature 6, having its' winding grounded at one-end as shown at 7, and the free end 8 connected to. a collector ring 9 on which rests the brush 10, se-
, cured to a plate 11. The stem of the brush holder passes through the plate, fromwhich it is insulated, and upon its upper end carries a spring 10, which is bent sharplyupward with a set to the left, whereby it serves directly as one terminal of the lamp 12.
The armature shaft 1 is journaled in bear- Q ings formed in side plates 13 and 13 and has one end projecting at 1%, to receive and carry the gear wheel 2, wh ch 15 connected through the train of gears 2, 2", etc.,.to a.
master gear on the spring drum 2". The
spring in this drum or on the main arbrev may be single, double, triple, or manifold, accordmgto the length of time the lamp is to burn without rewinding. I do not hereofa type which is well known, and specific differences will sufficiently appear from the illustration, the statement of operation, and the claims herein.
The side plate 13. carries a threaded socket which may be formed directly 'in'the plate,
for thebase of the .lamp 12, the circuit from this socket being completed through the metal side plate 13 to the shaft 1 of the armature and' so to the winding 6 thereon. In other words, one sideof the lamp is grounded on the frame, and the other side is directly connected through the lamp base and the spr1ng 10 to the brush 10, the collector ring 9 and the armature winding 8. This construction is not only extremely eflicientbecause of the small number of joints and connections between the generator and the translating device, but it is also cheap and easy to make.
The field magnets 18, the upper portion of their poles resting upon a base 19, which also forms the base for the entire lamp unit. The structure may be secured to its base in any suitable manner, but I have shown it as in describe the motor in detail because it is which is shown in section in Fig. 1, have secured through the casing 20, which is fastened to the base by screws 21 or in any other suitable I manner, and fits tightly over the crown of the field magnets, being shaped as shown in Figs. 1 and 3, so as to maintain the same against lateral as well as vertical displacement.v The casing is provided with a handle 15 which may be secured by riveting as shown, and on one side carries a bulls-eye 16 which when the parts are assembled comes into position over the lamp l2, and on 1. A self-contained lighting unit comprising the following instrumentalities: a base,
a magneto generator mounted on said base having field magnets, a rotor, and generating windings, a train of spring drivin gears connected to the rotor shaft on one side of the magneto, a' lamp mounted on the other side of the niagneto, circuit connections from said la'mpfto the generating windings, and a continuousmetalcasing surrounding the entire unit and secured to the base, said casing having an opening opposite the lamp, and a bulls-eye secured to the casing over said opening.
2. A self-contained lighting unit comprising the following instrumentalities: a base, a magneto enerator mounted on said base having fielf magnets, a rotor, and generating windings, a train of spring driven gears connected to the rotor shaft on one side of the magneto, a lamp mounted on the other side of the magneto, circuit connections from said. lamp to the generating windings,
' and a continuous metal casings'urrounding the entire unit andsecured to the base, said casing having an opening opposite one of the gears 1n the motor tra1n,'.and means fitted in said opening for stopping and starting the motor train, and thereby stopping and starting the operation of the generator and the, illumination of the lamp.
3. A self-contained lighting unit com rising the following instrumentalities; a ase,
a magneto generator mounted on said base having field magnets, a rotor, and generating windings, a train of spring driven gears connected to the rotor shaft on one side of the magneto, a lamp mounted on the other side of the magneto, circuit connections from said lamp to the generating windings, and a continuous metal casing surrounding the entire unit and secured to the base, said casing having an opening opposite one of the gears of the motor strain, and means fitted in said opening to engage said gear for the purpose of stopping the train, said means proecting outside the casing for manual manipulation, together with means also projecting through the casing for winding the spring motor.
In testimony whereof I aflix my signature.
