A. L. WHITE. LUNCH HEATER.
UNITED STATES PATENT I OFFICE.
AMELIA L. -WHITE, OF LIMA, OHIO.
LUNCH-HEATER.
SPECIFICATION forming part of Letters Patent No. 530,146, dated December 4, 1894.
Application filed February 16, 1894. Serial No. 500,396. (No model.)
invented a new and useful Lunch-Heater, of
. which the following is a specification.
My invention relates to'improvements in combined lunch-heaters and cookers, the objects in view being to provide a conveniently arranged portable heater for containing meals, particularly designed for workingmen or others who carry their meals to their places of business, whereby through the same they are enabled to enjoy a warm meal; to so construct the heater as to serve as an illuminator or lamp; to be readily cleansed and to afford intense heat for quickly warming or cooking the food contained therein.
Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.
Referring to the drawingsz-Figure 1 is a perspective view of a heater constructed in accordance with my invention, the same being shown as open. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a detail in perspective of the lampbody or base of the heater. Fig. 4 is an enlarged view of the lower portion of Fig. 2.
Like numerals of reference indicate like parts in all the figures of the drawings.
In practicing my invention I employ a rectangular tin box 1, locating about midway the same a horizontal shelf 2, forming upper and lower compartments. The upper compartment is subdivided by a perforate partition or shelf 3 which may be readily withdrawn, inasmuch as it is mounted slidably in opposite horizontal ways 4. Leading from the intermediate shelf 2 to the roof of the box at the back wall thereof is a flue or hollow wall 5, the said back wall being perforated at its upper end, whereby the products of combustion after traversing the under side of the shelf 2 may gain access to the external atmosphere and in so doing will also heat the upper compartment. Upon the shelf 2, I locate a bake-pan 6, and upon the upper shelf a plurality of smaller pans 7, each being designed to contain edibles.
The front of the casing or box is provided .ing.
with upper and lower doors designated as S and 9 respectively, the same having turn-buttons 10 by means of which said doors may be secured against opening, it being understood that the opposite edges of the door are suitably hinged to the side wall of the box or cas- The lower door is provided with a mica or transparent pane 11 so that the light contained in the lower compartment as heretofore appears may be reflected without the same, and thus the heater serves as an illuminator. A pair of keepers 12 are arranged upon the inner face of .the upper door, and these contain a knife and fork for use during ,the meal. A spoon and napkin may also be provided.
Arranged under the box or casing is a rectangular hollow base 13, the same being designed to serve as an oil reservoir, and this base is surmounted by a diaphragm 14: which is elevated thereabove by means of opposite depending flanges 15 which rest upon and are soldered to the aforesaid base. These flanges are furthermore provided with perforations so that air may pass under the diaphragm and over the base. The diaphragm is provided at its center with a perforated portion 16 which portion registers with a'circular opening 17 formed in the bottom of the box or casing. This perforate portion is provided with a central collar 18 which projects above the bottom of the casing through the central opening and also extends into the top of the base or oil reservoir. A conical cap 19 surmounts the bottom of the casing or box and covers the circular opening therein as well as the perforated portion of the diaphragm, and seated upon this cap is the burner-cap, the lower end of the burner being threaded into the collar that leads to the oil reservoir. By this it willbe seen that the air is fed between the bottom of the casing or box and the reservoir up through the cap to the point of combustion which latter is thus facilitated and the heat increased. A pair of staples 20 project from the upper side of the oil reservoir or base and through perforations formed in the bottom of the casing and locking-rods 21 are located in the casing and pass through the staples, thus locking the oil-reservoir to the under side of the casing or box.
Hooks and eyes may be used, or any other suitable fastening, for this purpose. This completes the construction of the invention with the exception of an oblong can or box 22 which is provided with a screw-cap 23 and is designed to contain coffee, tea, or other beverage.
It will be observed that the entire device may be conveniently carried by means of a hand-bail 24.
In practice the several pans accommodate baking device towarm things for the sick,
dry clothing, &c., all of which I contemplate as being within the scope of my invention. In such case, the flue 5 is arranged at each side of the box or casin g so as to insure greater and more uniform heating of the contents of the box.
Having described my invention, what I claim is- 1. The combihation with the box or casing having a circular opening, of a lower hollow base or reservoir having a collar extending upwardly through the opening, an intermediate diaphragm arranged under the box or casing and perforated opposite the opening and having depending flanges secured to the base and provided with openings, a cap surrounding the opening in the base, and a cured to the oil-reservoir and having a central perforated portion agreeing with the opening in the bottom, a collar passed through the perforation in the diaphragm and the top of the reservoir, a conical cap arranged upon the opening in the bottom of 'the casing, a
burner-cap arranged upon said cap and secured to the collar, staples extending upwardly from the reservoir through openings in the bottom of the casing, and locking-rods passed removably through the staples within the casing, substantially as specified.
3. The combination with the box or casing having the central opening in its bottom, of the rectangular oil-reservoir thereunder, the intermediate diaphragm spaced from and secured to the oil-reservoir and having a central perforated portion agreeing with the opening in the bottom, a collar passed through the perforation in the diaphragm and the top of the reservoir, a conical cap arranged upon the opening in the bottom of the casing, a burner-cap arranged upon said capand secured to the collar, and means for detachably securing the reservoir in place, substantially as specified.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
