IMPROVEMENT IN PORTABLE'LAMP-STVES.

Specification forming part of Letters PatentNno. 592,01 l, dated June l2, 1877 application led April 9, 1877. A

VTo all whom it may concern:

- and exact descriptiomreference being had to the accompanying drawing, forming part of this specication.

This inventionv relates to portablev lamp- -stoves for nursery use and other purposes, in or by which an ordinary hand or other portable lamp may be usedv to heat a kettle orother Vessel arranged over the lamp and carried by the stove.

The invention consists in a certain combination of parts, including an annular or other suitably-shaped open cap, on which the vessel to be heated is placed, removable legs constructed to connect with said cap, adjustable or screw-rod lower extensions applied to said legs, and hooking-braces connectingthe lower ends of the legs, the whole forming a light, Icompact, and steady support or stand for the vessel to be heated, with every facility for adjusting it to suit diii'erent levels or heights of lamps or lamp-chimneys,and admitting of a ready detachment of the parts to promote portabilityr and facilitate stowage away in a reduced space or compass.

The invention also consists in a novel construction of the cap of the stove on which the vessel to be heated is placed, whereby a free diffusion of the heat-under the whole surface -of said vessel and a draft for the heating. curirents or gases over the cap and under the ves- :sel is obtained.

Figure 1 represents a view in perspective of a portable lamp-stove constructed in accordance with the invention, and as erected for use. Fig. 2 is a view of the same when its parts are dismembered and arranged for stowing away or transportation.

A is the cap, which is preferably annular, and which serves .to support the vessel B to be heated by a lamp, G, beneath. This cap is provided with three or more pockets or staples, b, on its under side, to provide for the attachment, in a readily-removable manner, of the legs D of the stove. Said pockets might be made by simply cutting the cap, as, for instance, by making two parallel incisions init, and bending the cut portion to receive the end ofthe leg. p The legs D, which may be made of sheet metal, and of a corrugated form in their transverse section to give them sti'ness, have their upper ends c bent to enter the pockets b in the cap when erecting the stove.

The lower ends d of said legs are also bent to I form screw-plates or boxes for screw-rodlow er extensions E to said legs, whereby the stove may be adjusted to different levels or irregularities of surface on which it stands, and the cap A be raised Or lowered to suit different heights of lamps or lamp-chimneys. The lower bent ends d of the legs also serve to carry and provide for the attachment of braces f, which give increased stability to the stove, and keep its legs at their proper outward set or spread, said braces being attached in a free or jointed manner at their one end to the ends or projections d of certain of the legs, and hooking at their opposite ends into eyes of the adjacent legs.

When it is required to disineinber the stove A for stowing away or for transportation it is only necessary to detach the braces f at their hooked ends from the legs D, and to detach said legs with their attacbed-screW-rod extensions E from the pockets orstaples b of thc cap A, after which the legs, screw-rod extensions, and braces may all be arranged in a straight or parallel and flat manner upon or across the cap A, as shown in Fig. 2, thus insuring great compactness. y

The upper surface of the cap A is dished or depressed, so that when the stove is erected and the vessel to be A"heated placed thereon there is a free distribution or diffusion of the heat from the lamp under the Whole bottom i of said vessel, and, to further promote the efficiency of theJ heating-currents, said cap is constructed with upper grooves or perforations g extending through the outer edge of the cap, thereby creating a draft forthe heat ed gases and currents over the cap and under the vessel being heated.

.I claim- 1. The combination, with 'the annular or perforations g extending through the outer open cup A, of the detachable legs D, the edge of the cap, essentially as and for the screw-rod extensions E, and the hookingA purpose herein set forth. braces j', substantiallyas specified. MILTON T. RICHARDSON.

2. The annular or open cap A of the stove, Witnesses: constructed with a depressed or dished upper HENRY T. BROWN, surface, and provided with upper grooves or MICHAEL RYAN.
