BATTERY HAND-LAMP.

Application led April 2, 1920.

T0 AZZ fw from it may concer/a @e it known that I, Gr. Srnns, a citizen of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Battery Naud-Rennes, and I do hereby declare the following to be full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to maire and use the same.

rThe present invention relates to battery hand lamps of the type in which a immature lamp is supplied with current from a bat-y tery, the lamp having a reflector and a lens with means for holding the reflector and lens in proper operativeposition with respect to the battery.

T he present invention relates particularly to the lens-supporting ring or collar and to the manner in which the lens and reflector are gripped and held.

ther objects and advantages will become clear from the following detailed description, which is to be taken in conjunction with the accompanying drawings, wherein- Figure 1 is an elevation of a hand lamp partly in section;

Fig. 2 is a fragmented sectional elevation through a hand lamp having an enlarged head;

Fig. 3 is an enlarged fragmental detail of the embodiment illustrated in Fig. 1; and

Fig. 4 is a similar detail of the embodiment illustrated in Fig. 2.

The hand lamp illustrated in Fig. 1 comprises a casing 1 of liber or other suitable material, containing a battery of dry cells 2, the uppermost Carbon electrode 3 or" which contacts with the inner terminal of the lamp 4. The outer or threaded terminal of the lamp is carried by and makes electrical connection with the reflector 5, the outer edge of which is in the form of a flange 6 covered above and below by an annular ring of ber or other suitable insulating material 7 wrapped about it. Casing 1 carries the usual threaded front collar or fitting 8 to which is threaded the lens-supporting ring 9. rThis ring has an inwardly extending flange 10 as is usual, but the lens 11 instead of being held loosely in the ring and liable to drop out when the ring is unscrewed, is, on the contrary, closely held between flange Specicaten of Letters Patent.

Serial No. 370,842.

l() and an inwardly extending ledge 12 which seats on the upper fold of' insulation 7 and so holds reflector 5 to its seat on the end of the tubular casing.

s a convenient way of' making the structure above described, the ring 9 is initially in the form of a straight cylindrical tube, and by usual spinning operations is folded inward at 12, and this fold is then flattened to form the ledge on which the lens 11 is to seat. The lens is then inserted and the end of the tubing is spun over at 10 to tightly and permanently lock the lens in ring 9. Screw threads may be rolled into the lower part of' the ring and the ring may be knurled and otherwise shaped, as is common in this art.

The hand lamp illustrated is provided with a spring finger 13 and a switch 14, the details of which form no part of the present invention. In the embodiment illustrated in Fig. 2, the lamp 15 is threaded into a metal cylinder 16, the upper edge 17 of which is riveted over to grip the inner edge of reflector 18. The outer edge of the reflector carries a flange 19 with insulation 20, as in the modification first described. The threaded front collar 21 carries a flaring head or fitting 22, the enlarged portion of which is threaded, as is customary, to receive the threaded lens holder 23. This lens holder has a lens gripping flange 24, a smooth cylindrical periphery 25, an integral fold 26, forming a ledge on which the lens 27 is seated, and has the usual screw threads for engagement with those on the flaring head of' the hand lamp.

If desired, the lens of either modication may have a recess in its bottom face, as illustrated in the drawing.

1. In a battery hand lamp, the combination of a threaded front fitting, a lens-sup porting ring threaded thereto and having a flange and a ledge, a lens permanently gripped between said flange and said ledge, and a reflector removably gripped between said ledge and said fitting.

2. In a hand lamp, the combination of a casing having a threaded front fitting, said fitting having an inwardly extending flange, a lens-supporting ring threaded to said fit ting and having a flange and a ledge, a lens permanently gripped between said flange and said ledge, and a reflector gripped between said ledge and the flange of said fitting.

3. In a hand lamp, the combination of a casing having a threaded front fitting, said fitting having an inwardly extending flange, a lens-supporting ring threaded to said itting and having a flange and a ledge, a lens permanently gripped between said flange i and said ledge, and a reflector having a flange, said flange being wrapped about with 10 insulation and being removably gripped between said ledge and the i'lange of said tting, substantially as described.

In testimony whereof I afiix my signature.

FREDERICK GRAHAM SPIERS.
