IM PROVEM ENT IN FOOT-STOV ES.

Specification forming part of Letters Patent No. 111,876, dated March 8, 1864.

To vall whom it may concern.'

resident of Canton, in the county of Norfolk and State of Massachusetts, have invented a new and useful Foot-Stove or Warming Apparatus; and I do hereby declare the same to be fully described in the following` specification, and represented inthe accompanying drawings, of which- Figure l is avtransverse section of the apparatus, it being taken through the entrance door of the case. Fig. 2 is a transverse section taken in a plane at right angles to that of the first section. Fig. 3 is a top view of the lamp or heater.

My invention is an apparatus intended especially for warming the feet of a person; and it may also be used as a lantern for affording light.

In the drawings, A represents a cubical box or case as not only provided with a door-opening, a, and a door, b, thereto arranged on one of its sides, but as having each of its other sides, either in whole or in part, transparent, each of such sides, as shown in the drawings, being made with an opening, in which is iixed a plate or pane, c, of glass. The top plate, d, of this case is forarninous, or made with numerous iine or small openings or holes, and has extended from it a series of screws, e e e e, which go through the top plate, f, of a guard, G, and have nuts on them and below such plate, the same being for the purpose of adjusting the guard relatively to the foraminous top of the case. The guard is made with a rim or flange, y, to extend down from theV edges of the plate f, the purpose of such rim being to intercept heat and smoke which may arise from the flame of a lamp, B, which is arranged within the case and underneath the center of the guard-plate. There is a passage, h, between the flange g and the sides of the case.

The lamp has two wick-tubes, t' and k, which are arranged at a short distance apart and have an air conduit or passage, l, between them. The air-passage. is open only at top and bot-tom, and at its bottom it leads into or opens directly out of a covered cup or chamber, m, which surrounds thetwo Wick-tubes, and has its sides perforated in order to allow air to pass freely into the cup, from whence it will liow into, and through the passage Z and impinge against the internal surfaces of the iiames from the two wicks. These iiames, however, from their proximity, will practically unite and form one iiame, which derives a great part of it-s oxygen from the current of air which may be discharged into it by the passage Z. By so making the lamp there is little or no chance of the iiame smoking when kerosene or other hydrocarbon iiuid is employed in its reservoir n.

To each wick-tube there is applied a wickelevator, o, it consisting of a spur-wheel, p, and a rotary shaft, q, provided with a milled head', r. One of these elevators is arranged so as to enter the inner side of one wick-tube, the other elevator being-arranged so as to enter the outer side of the other wick-tube. In this way each elevator can be turned in the same direction for either raising or depressing the wick.

In the operation of my said foot warmer or stove the heat from the ame of the lamp as it rises impinges directly against the center of the guard, and, as the guard is an inverted dish, such heat will spread laterally throughout the same and be retained in a body, thev surplus heat escaping underneath the edges ofthe guard and passing off through the passage around the guard.

The guard, made as described, not only op crates to diffuse the heat and retain it and radiate it to the foot-rest .or foraminous top of the case, but it serves to protect the feet of a person when on the top of the case from becoming burned by concentrated heat from the iiame of the lamp. Were the guard a simple plate the heat would not be retained'within and by it and be equally radiated from it, as will be the case when the guard is made as an inverted open dish or chamber.

What I claim is- The improved foot-stove, as made not only with the foraminous top, but with the chambered guard, arranged with respect to such` top and the lamp substantially in the man. ner and so as to operate as described.
