HATTIE G. COOK, OF MCGIRK, MISSOURI.
HOTBED.
Application filed October 4, 1913.
To all whom t may concern Be it known that I, IIATTiE Gr. COOK, a citizen of the United States, residing at McGirk, in the county of Moniteau and State of Missouri, have invented certain new and useful Improvements in I-Iotbeds, of which the following is a specification.
This invention relates to portable hot beds particularly adapted for use in cold weather for maintaining a certain predetermined degree of heat around growing plants, and which is especially designed for domestic use.
The object of the invention is to provide a hot bed which is easily portable, which is provided with heating means 'for maintaining an even temperature, and which is so constructed as to conserve the heat in order to prevent loss by waste.
Other objects and advantages such as simplicity, cheapness, durability, and efliciency will be carefully brought out in the following specification and accompanying drawings, in which, 1
Figure 1 is a longitudinal sectional view through my device, Fig. 2 is a top plan view with a portion of4 the cover removed, and F ig. 3 is a detail sectional view.
Referring more particularly to the drawings, the numeral 1 designates an outer shell preferably of galvanized iron or other suitable material which is bent over at its upper edge, as shown at 2, and provided with a shoulder 3 forming a flange extending around the casing 1. A plurality of sheets or layers of asbestos 4f are disposed within the casing 1 and are co-vered and secured in place by an inner shell 5, preferably of copper.
The entire device is supported upon legs 6. A cover 7 is hinged upon the casing 1 by means of hinges 8 and comprises a frame or sash 9 provided with a pane of glass 10. In order to prevent cold air from entering the device or warm air from escaping I provide felt l1 at the junction of the cover 7 with the casing l, as shown.
In order to heat the interior of the device I provide within the inner easing 5 tanks or receptacles 12 disposed above iues 13 Specification of Letters Patent.
Patented Nov. 16, 1915.
Serial No. 793,400.
formed through the casing 1 and the shell 5, said iiues being adapted to convey heat from lamps 14 or the like, which may be supported upon the Hoor or upon brackets 15 secured upon the legs 6. The tanks 12 are adapted to contain water which is free to circulate from one tank to the other through a plurality of tubes 16 which extend longitudinally of the device in an inclined direction and communicate with the interiors of the tanks 12.
It will be readily understood that al though I have described and shown asbestos as being the insulating medium disposed between the casing 1 and the inner shell 5, I may use mineral wool, charcoal, cork, or other fibrous material.
It will be understood that earth will be placed within the inner shell 5 and its upper surface may be iiush with the tops of the tanks 12 if the tanks are formed open at their tops or the earth may extend above the tops of the tanks 12 in which event the tops would be closed and provided with small upright pipes 17 extending above the surface of the earth for allowing the escape of any steam or heated air. In order that the earth contained within the inner shell 5 may be removed, I preferably provide a door 18 formed in the casing and hinged., as shown at 19.
Having thus described my invention, I claim:-
A device of the character described, comprising a heat insulated casing having flues in its bottom, a pair of tanks upon the bottom of said casing over said iiues, the tops of said tanks being closed, means for heating said tanks through said fines, pipes connecting and communicating with said tanks, and vent pipes on and communicating with said tanks and extending above the tops thereof.
In testimony whereof I affix my signature in presence of two witnesses.
J. J. CHAMBERS, J. G. HUGHES.
