AUTOMOBILEHEATER.

Specification of Letters Patent.

a subject of the King of Great Britain, and

.a resident of Saskatoon, in the Province of Saskatchewan and Dominion of Canada,

have invented-a certain new and useful Improvement in Automobilc-I-leatcrs, of which the following is a specification.

This invention is an improvement in heaters, and has particular reference to a heater forautomobiles controlled. by the exhaust from thecngine.

An object of the invention is the provision of a heater casing adjustably mounted upon a suitable support in a vehicle,'where' by the same may be moved to a position preferably beneath'a seat and also adjusted in such a manner as to beemployed as a foot warmer.

Another object is to provide a heater casing wherein a system of heating pipes is connected to the exhaust of the engine and the fi0w' of burnt gases through'said pipes.

regulated by a novel valve mechanism controlled by the operator. i

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which for the purpose of illustrating the invention is shown in the accompanying drawings, wherein F'gure 1 is a perspective View of the heater, showing the same applied to a vehicle;. 1

Fig. 2 is a similarview showing'the valves for controlling the flow of the exhaust from the exhaust pipeto the heater casing;

ing 12 are up urality of spaced heat outlet chambers 13 having suitable covering 1*}, said chambers having an outlet on one side of the casing 11. For the purpose of regulating the amount of heat coming from the chambers 13, t lore is preferal'ily provided a a slide member 13 ex'temling longitmlinally of thecasing 11 and mounted in the guide flanges 16 forn' ed thereon. This slide memher is provided in its front with a plurality of openings 17 corresponding in number to. p

the number of chambers 13 and said openings are adapted to register with the outlets of said chanibe rs in order to permit of the 1." heat in the hem-r casing makmgits exit therefrom. Th member 15 is provided with a i a knob or handle 18, which may be grasped by the operator in, order to adjustsaid memher back and f1 llllh in order to regulate the size of the heat exit openings.

As shown in Fig. 1, one of the adjustedposit ons of the heater casing is beneath the seat 8 the v1 :hicle' and said casing is retained 111 this position by means of the straps 19 or 01 her holding devices-which are hinged at 20 to the floor? of said vehicle.

' By hinging the casing 11 through the medium of the str: ps 19, it is readily apparent that the said rasing may be swung ,from

the heater may tensed as a foot warmer.

In order to circulate the exhaust gases through the heater casing, the exhaustipi'pe '9 is tapped at 21"for the reception ofga vertical to horzontal position whereupon 1 let end 25 of :;aid pipe terminates udiecent the inlet or d 23. The pipe 24 is'provided with a. brunch. pipe 26 which extends longitudinally of the -heater casing-1 and throughthe several chambers 13. vToallow for theadjustmznts of the-heater chamber-Q 1 from vertical to horizontal positions and vice versa, the circulating pipe 24 isjpr'm vided adjacent its inlet and outlet ends the universal coupling 27 shown in section in Fig. 5. .11 through which theinlet and outlet ends of the pipe 24 extend are elongated, as shown in Fig. 1 to ermit of said adi'uste seen that shou d it The openings 28 in the casing ,normally in an opened position;

the branch pipe 22 and is normally in closed position. An angular bracket 31 is secured upon the top of the exhaust pipe J, and has pivoted to a free extremity thereof a double bell-crank lever 32, having two ol' its arms bifurcated at the ends as indicated at Iii-l, one. of the bifurcations receiving an arm 2-H which actuates the. valve. 2!), while the other bifurcation receives a pin extension 35 carried by'an arm 36 which operates the valve 30 about its pivot. Connected to the extremity of the third arm of the lJQllC-T'illlli lever 32 is one end. oi a flexible connection #57. which passes over a pulley AS and extends to a point in the vehicle readily accessible by the operator. A spring 2-59 secured to the bell crank lever and to the arm ll holds the valves 2-9 and 30 in normal position. it will be seen from this description that by exerting a pull upon the connection 37, the val ves '29 and 30 will be. respectively closed and opened, and the exhaust gases will he shunted through the circulating pipe 24 in the heater casing; \Vhen the connection 37 is released the valves are returned to normal position by the spring 39;
