To all whom it mag/concern:

Be it known that I, OLIVER A.:L0vELEss, a citizen of thel United States, and ay resident oi Watersmeet, in the county of Gogebic and Staterof Michigan, have invented a new and Improved Portable. Lamp, oi which the Jfollowing is a full, clear, and exact descriptio'n.'-

The invention an improvement :in prtable lamps for campers, hunters', etc., 'and consists in general of a portablegasfrenerator, preferablyl acetylene, areilector raving anvinner concave reflecting surface, and a burner arranged within the reiiector atv the center' and havinga su ply connection with the generator, the re ectoribeing perma nently openat' the front for the escape of' heat, and with the walls of, the reflector around the burner imperiorate to prevent.

the passage oi the air-therethrough in moving forward andthns extinguishing the light.' The invention further contemplates the construction of the reiiector in a manner to be interchangeable with either a helmet or crown and a supportin standard;

Reference is to be ha to the accompanying drawmgs forming a part or' this specification, in which similar characters of reference indicate corresppnding parts in all the-views. Flgurel illustrates m improved portable lam as assembled an constructed to be carried on 'the p rso l; Fig. 2 is a view of the same as a plied'ft'o a supporting standard inv the bow o a boat 31s la central vertical' Sectionl throng thel''reiiector andV crown shown mFig, 1' 'Figgft is a central vertical section through the a 'petylene generator subl p AFigs. 1 and 2,y the marginal a e 300i; the

' bodies in its construction an cuter Water tank 10, aninnercalcium carbid tank 11 and a cover '121 the cover. being connected to and su porting the carbid tank by: a central up;l rig t stem 13 which. is threaded.- into the outer central boss 14 of theicov r and is formed integral or otherwise ri idly attached' Jwith the walls of an upwar ly-extending i pocket 16 formed in the base-oi. the tank 11,

the said pocket 'being closed at the boomcfv the carbld tank by a perforated slide 17 `and communicating at its upper end through, er-

.it'orationsfl18, with the. carbid ztank. A he,

slide 17 admits of the passage ofwater into sorbent material 19. In'gtrdditiim"to the supf I port afforded thecarbidt/ank by the stem 13 this tank is further supported from the water tank at both the sides and bottom, by bowed springs 20. Both the water and carbid tanks have' inwardly-turned iianges 21. and

22 respectively, providing a seat for a gasket.

23 interposed betweenjthe'tanks 4and cover, and forminga gas-tight )o lnt when the cove;` 1s secured' in' place.- This securing of the cover is accomplished by the upwardly-projecting'studs 251 lattached to the side of the Water tank and having thumb-nuts 25 bearino' on the upper face of the cover. .v

n the boss4 14 is-threaded a manusllycontrolled cock' 26,. the inner stem or'thread-- 1 ed portion `of which is counterbored or en# larged to receive la conical screen 27,'Wl11ch. operates to strain the gas as 1t passes from the generator. The -gas leaving the carbid passes lthrough passages 28 of the cover, ar-

.mused about the `upper threaded portion of p the stem 13. Y i

A dished reflector 29 is constructed with a rearwardly-turned marginal flange 30 and is provided'at the center with aburner 31 with which the generator connects through ia iiexible tube 32'.4 -The front of the reflec-l tor remains permanentlyopen in order that the heat from tlie'biurhcrmayrapidly esca e, and the walls- 'ector around the 'urner 'are imperfratez; prevents the airfrom blowing throilglathe reflector and extinguishing thelight'. t
