ELECTRIC LAMP FOR HELMETS AND SIMILAR HIElAD-COVERINGS.
Specification of Letters Patent.
Patented Oct. 27, mos.
Application filed January 2, 1908. Serial No. 409,078
To all whom it may concern:
Be it known that I, JOI-IANN HEINRICH DRAGER, a subject of the Emperor of Germany, and resident of Li'lbeck, in the German Empire, have invented certain new and useful Improvements in Electric Lamps-for Helmets and Similar Head-Coverings, of which the following is a specification.
. The present invention relates to im rove ments in electric lamps for helmets mown as miners or firemens helmets and similar head coverin s such as are usuall worn in mines and other places wherein t e atmosphere ischarged with noxious gases.
Before Davys safety lamp was used in mines it was the custom for the miners to attach their lam s on. the head. The safety lamp however lad to be carried by the hand, since it Was necessary to constantly watch it. Since that time it became quite general to carry the miner's lamp in the hand and this custom has now also been conferred to electric lamps. Though it'has been suggested to attach the lamp to the cap over the forehead and to wear the electric battery somewhere on the body, yet it has been found that the electric wire or cable enerally was in the way, a hindrance in han ling and therefore was a constant source of trouble. In extinguishing fires or in life-saving by aid of respirating or inhaling apparatus the electric lamp is an'inconvenient implement, since both hands are first engaged with the lamp before any work can be done. Therefore I have provided means to carry the lamp on the head without the drawbacks above pointed out. This task is solved by attaching not only the electric lamp but also its battery to the helmet, cap or mask or the like. The electric lam s used in mines heretofore and carried by t e hand, are much too heavy for this purpose. I have therefore ta ken in consideration that respirating or life saving apparatus are constructed so that they can be used for two hours and that it istherefore not necessary to construct the lamps as has been done heretofore to give li ht for eight hours. The size and weight of the battery also can be reduced to a great extent. My invention moreover provides for the special arrangement of the parts of the lamps and the battery.
Reference is had to the accompanying drawing in which:
in front.
Figure 1 is a vertical section of a helmet having my improvement attached thereto placed on the head of a person; Fig. 2 a front view of Fig. 1; Fig. 3 a ack of the same helmet. Fig. 4 a detail elevation of the lamp and battery separated from the helmet and Fig. 5 a planof Fig. 4e
The helmet as a may be of any usual construction and may be replaced by a cap or a simple mask to suit the requirements. At the back of the helmet a receptacle 6 for the battery or accumulator b is arranged. to hang down, preferably in a somewhat obli ue position, so as to serve as a protection to t e neck. The weight of the battery is more of an advantage than disadvantage because it'serves to balance the weight of the helmet, which has itself the tendency to pull the head down The weight of the battery and its receptacle may be siich that the com lete apparatus does not weigh heavier in out than in the back, and the consequence of this favorable distribution of the complete weight is, that the neckbelt a of the helmet does not press against the veins of the head, to such an extent as is the case with helmets heretofore. It is not necessary that the parts of the lamp be firmly attached to the helmet,
but it is rather of advantage to construct the lamp d; the conductor 0, the contact breaker and the receptacle e for the battery alltogether as an integral ap )aratu's, which can be placed on the helmet, w 1en needed. To this end as is shown in Fig. l the conductor is arranged within a tubular'casing h which is made integral with the receptacle e and lamp-casing cl. This apparatus, Figs. 4 and 5, may be provided with lugs t for detachably securing it to thehelmet a.
The lamp is referably provided with a reflector f, which together with the electric light itself when properly positioned illuminates only so much as can be seen through the opening or window 9 of the mask or helmet a, so that the complete space, in which the wearer of the helmet is working a pears to him to be illuminated, no matter w ich way he turns his head, whether to one side or up ward or downward.
I claim:
1. A device of the character described comprising a head covering having a receptacle thereon, a battery mounted in the receptacle, a casing integral with the receptacle dctachabiy connected tQhth'e covering, a tion on the hinde'r'part of the head-covering lamp 1n the casing, and avconductor in the that it covers the neck of the wearer and 10 tter connecting the battery and' lamp. serves as a protection to the same.
An electric lamp for head-coverings in 5 combination with a battery and a conductor connecting the lamp with the battery the Witnesses: v 1am being attached to the head covering on FRIEDRICH PLATH, its ont part and the battery in such posiv Jons. WULF.
