Ouriinvention relates to a' V'Ininerslamp and more particularly-to an electrical lamp Which may 'be used in lieu of the ordinary usually carried by miners.

The object of our'invent-ion is to provide a lamp of the class above referred to which form and simple andstrong in construction.

In the accompanyingdrawings which illustrate one formof lamp made inV accordance with-.our invention, Figure 1 is a side view of the complete lampand attached battery clip; Fig. 2 is a sectional view of the lamp only, the parts beingshown separated;

.Like marks of referenoerefer to similar lparts in the several views of the drawings.

V,10 is a casing forming the body of the' lamp. This casing 10 is cup-shaped in form and is preferably made'of sheet metal.

11 is a wire hook similar to the hooks usually attached. to miners lamps and 'adapted to be inserted in the band-of the wearers cap. This hook 11 `projects through the casing lO'near the bottom .thereof and is provided on the interior of the casingwith a loop 12. The wire ofthe hook 11 is formed of strong metal and the loop 12 is made slightly larger than the interior of the casing k10 so'that the loop 'must be compressed to be inserted into the casing. By this means the loop 12 is -held firmly against the sidesof the casing 10 by its own `elasticity.. This loop 12 is clamped against the bottom of the casing 10 by means of a lamp socket 13. This.socket 13 'is of the usual form and is held in position by meansot screw-headed bolts 14, and nuts 15. In this manner the hook 11 is firmly secured in po- Mmnnfs LAMP. y.

A Application mea March 7,- 1910. serial no. 547,831;

lamp 16. This lamp 16 projects throughv an opening'l? in an inner cap 18 which is placed lnthe interior in the casing 10, as best shown in Fig. 4.

The face ofthe cap 18 is'curved, as best shown in Fig. 2, so that the said cap forms a convex reiector for the lamp so as to disperse the Ali ht from the lamp. Bearing against the ace of the cap 18 1s a substantially semi-spherical glass cover 19 for protecting the lamp 16 land also for diffusing the .light fromv the' said lamp. This cover 19 is provided'witha fiange 20 Whiclris clamped ybetween the innercap 18 and an outer' cap 21 adapted-t0 slip over the casing 10, the cap 21 being provided with an opening 22 for the passage of the 'cover 19. The

outer cap 21 is heldinposition-on the casing l0 by means-of screw-headed bolts v23 passing through openings 24' in the said cap and engaging With nuts 25 inthe interior lam'p socket 13.

This filling 26 surrounding the lamp socket may be formed of asphaltum 10. These nuts rare embeddedV in an insulating filling 26 surrounding theV or any other suitable non-frangible material.

The terminals 27 of. :the lamp socket 13 are 'placed between the block 31`and a second insulatingblock 34`and the-two blocks are secured together byv means v of screw-headed bolts 35 and nuts 35. The bolts 35 pass not only through the blocks 31 and 32 and the s ring contacts 33 but also throughloops 3g formed in the ends of the strands 28 so ,as to make good electrical contact between the ends of said strands andthe said contacts. This construction also prevents' in-v jury to the strands of thel cable `29`at thel poinnwhere the strands are divided.' y

The operation of our lamp will be evident of a cable 29 formin any convenient transparent cover said socket; an "inner, cap.
