. To all whom it may concern:
Be it known that I, HERMANN Riemann, a
subject of the King of Prussia, residingat Berlin, Germany, have invented new and useful Improvements in Miners" Electric Lamps, of which the following is a specification. 7
This invention relates to an improved electric lamp for miners use, of the typehaving an accumulatorcombined with an incandesceuce lamp and the ob ect being tQ PI'OVIdB an improved and more convenient construct-ion particularly as regards the means for effectively locking the lamp and accumu-' lator receptacle or casing.
In the accompanying is an elevation partly in" section through such a lamp, and Fig. 2 is a perspective view of a part of same on a larger scale.
The electric cell or accumulator a is placed in a casin I downward y extending contacts d and e which complete the circuit with the contacts f and g of the accumulator or source of electricity.
The upper side of the lid carries the incandescence lamp h and the usual lamp)gl'ass z, the glass being in turn surrounded y the usual protective cage is surmounted by the reflector and carrying hook Z.
The cover fits into a recess n in the battery case, which it square maybe on one'side as shown, by means of a flan e m-,either'contiuuous or interrupted, an is held at one point, preferably 0 posit-e to the recess a by a locking device'w 1ch consists of a catch p. hinged to a portion'o attached to the case I) and provided with a hook and two studs or a fork r. The upper s1de of the cover carries an internally threaded screw collar 8. into which a flange k on the rotective cage 7.: of the lamp is screwed, and which is also adapted to hold down the base of the glass. the outer side of the collar s.a movable ring t is rovided This ring may withadvantage e fitted with two handles a to en able it to be taken 'hold of easily. The ring is also provided with a stop 0 and a per forated projection 'w, and, at the point opp;-
site the catch, with a ste ped recess .70.
screw collar isprovide with a recess 2,-
which comes into positionopppsie to, and J when the cover; I
through: the recess a; in the ringt and enter- 1) on the cover a of which are,
receives thehook g of the cats cover is as. "and finally the upper side 'ofthe cover-carries a lug which like the projection w on the ring is perforated;
If the lampis to be locked, the cover carrying the lamp and other fittings, is placed on the case, its fiangem) having been inserted into the'recess n inthe casing. The heck of,
the catch ;0 is then insertedinto the ring which should be in such a position that the stop a on same abuts against the lug 3/ on the The hook is thus caused to pass the recess z in the screw collar 8. The ring at is thenturned around so that it passes behind the head of the hook until its perforated proy 'ection w encounters the lug y and a seal can drawing: Figure 1 attached by meansof the perforations in these. two: To keep the protective cage k also from being unscrewednt lsturned around until one of its wires comes into position so that the'two limbs of the fork r of catch 9 can be placed over it, or else'the flange of the cage may be provided with recesses and the like to, engage with a nose on the catch p, so
that when the lamp is sealed, it cannot be opened or taken to pieces in any way without damaging the seal. What I claim is: I
1. In a miners electric lamp, and in com-v 'b1nat1on-, a casing for the source of current,
a removable cover for same, a lamp carried by said cover, a. rotatable ring on said cover, and means carried by said ring and easing res ective whereby the rotation of the ring wil hold t e cover to the casing. a
2. 'In aminers .electric lamp, and in combination, a; casing for the source of the current, a removable cover for same, a lamp carried b said cover, a rotatable ring on said cover aving a recess, and a catch,on said casing adapted to engage in the recess of said ring and to be held when the latter is rotated.
.3. In a'miners electric lamp, and in com bination, a casing for the source of the current, a removable cover for same, a lamp carried by said cover, a collar forming part of -said coverpnd having a recess,a ring rota table on sald co1lar,-and also having a recess,
and a catch on said casing having a part adapted to engage in the recesses of said r ng. and collar and to be covered by the ring when rotated.

, can eng'age, arin' having a recess and ro adapted to engage-in therecessof said ring fable cover forsaidcasing, a flangeon said 1 cover to engage said recess, a lampand a i-ent and-having a recess in same, a removablQFCOVGL' for said casing, a flange on said cover-to engage said recess, a lamp, a'lamp cover, a screwedflange carried by said cage adapted to seat: on the lamp glass, a screwed and with which the 'screwed flange of the cage tatableon said col ar, a catch on said casing and to be held when the latter is rotated, and a fork on sai'd'catch to engage a part of i 1 the protective cage.
6. In a miners electric lamp, and in comvi bination, a casing for the source of the curi "rent, a-lug on said casing, a removable cover for same, a lamp' carried by said cover, a rotatable ring on said cover having a recess, a projection carried by .said ring, and a catch on said casing'adapted to engage in the recess of said ring and to be held when thelatter is rotated and brought into a position when the lug and projection respectively are abutting so that thetwo may be sealed together.
7. In a miners electric lamp, and in combination, a casing for the source ofthe current, a removable cover for same, a lamp carried by said cover, a collar having a recess and forming part of said cover, a ring rotatable on said collar and having a stepped recess,a stop on said ring, a perforated projection also on said ring, a perforated lug on said cover against which the stop is adapted to abut and a catch on said casing adapted to engage the recesses in the collar and ring and to be held when the latter is rotated, the perforations of the lug and projectionrespectively being adapted to receive a seal;
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
