MEANS FOR VARYING THE TEMPERATURE @E messes.
Specification of Letters Patent.
Patented net. 15, teen Application filed may 2, 1919. serial No. 294,322.
To all whom it may concern."
Be it known that I DANIEL CLARK, a subject of the King of Great Britain, and resident of the city of Edmonton, in the Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Means for Varying the Temperature of Cars, of which the following is a specification.
This invention relates to improvements in means for varying the temperature of cars, and particularly those cars designed for the conveyance of fruit, vegetables, grain and the like which in the winter it is desired to maintain above a given minimum, and in the summer below a given maximum, and the objects of the invention are to provide a simple and effective means for effecting a uniform distribution of circulation of the heat conveyin or extracting gas, and it consists essentially ofa car having an inclosed heating chamber at each end with temperature varying means therein, and ducts on opposite sides of the car extending from end to end thereof connecting the heating chambers, whereby air will flow in opposite directions in the opposite ducts, all
as hereinafter described in detail in the accompanying specification and drawings.
In the drawings: 4 Figure 1 is a longitudinal sectional elevation of an embodiment of the invention. Fig. 2 is a cross sectional view through the same on the line 0cw 'ofFig. 1.
Fig. 3 is a sectional plan view on a reduced scale showing the circulation of air in the floor on the line y- -y of Fig. 1.
In the drawings hke characters of reference indicate corresponding parts in all the Referring to the drawings, A represents a car of any well known design having a the walls and roof being preferably double Walled to form a better heat insulation. B and 0 represent temperature varying chambers at opposite ends of the car. "lhese chambers are closed except where the duct, as hereinafter described, communicates therewith and are conveniently formed by partitions 14 and 15 which extend from the "the chamber B top to the bottom of the car. The car is I formed in the floor with two longitudinally extending ducts 16 and 1'? on opposite sides thereof and which place the chambers B and Q in communication with each other.
The temperature varying chambers B and Q contain temperature varying devices E and F which may be stoves] in cold weather and refrigerating devices or ice chambers in hot weather. The stove in is placed opposite the end of the duct 17 while the stove F in the chamber C is placed opposite the duct 16. It will be seen that when the stove is in use a contlnuous circulation of warm air will be afforded. The stove E will draw cold air from the duct 17, which air will be heated and rise within the chamber B, then turn in the said chamber and pass downwardly through the duct 16 to the chamberC where it will be heated by the stove F, and turn in the chamber and pass again into the duct 17 To concentrate the draft of the stoves E and F suitable partitions 18 are provided adjacent thereto.
The temperature varying device-s E and F may be of any suitable character. When stoves are used they may be of any desirable type having any well known means to supply with air and maintain combustion in the well known way. en refrigerating de vices are used any of the well known forms of ammonia plants may be used, or if desired an ice chamber or refrigerator may be used.
As many changes could be made in the above construction, and many apparently widely difl'erent embodiments of my invention, within the scope of the claims, .constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as 1llustrat'ive and not in a limiting sense.
What I claim as my invention is:
A car having two ducts in the floor thereof extending from end to end of the car, temperature varying chambers at opposite ends of the car connected to the said ducts, temperature varying devices in said chambers, the temperature varying devices at opposite ends on? the car being placedl opposite In Witness whereof 1 have hereunto set difierent ducts wherehy air Will be caused. to my hand in the presence of two Witnesses circulate in opposite directions in the two DANIEL CL ducts, and partitions in the temperature Y varying chambers adjacent to each tempera- Witnesses: ture varying device adtapteci to concentrate 1 RUssnL S. SMART, the draft around the same. MARY E. Knox.
