AUXILIARY DEVICE FOR GAS-ENGINES.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed June 27, 1916. Serial No. 106,177.

To all whom it may concern Be it known that I, Jnssn D. LANGDON, a citizen of the United States, residing at Vaterville, in the county of Douglas and State of Washington, have invented certain new and useful lmpromments in Auxiliary Devices for Gas-Engines; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an auxiliary device for gas engines, and is -more particularly designed for use in connection with automobile engines, and embodies improvements in the construction disclosed in my former Patent No. 1,186,319, dated June 6, 1916.

One of the objects of this invention is the provision of a device connected with the main water cooling system of the engine in a manner to provide an efiicient auxiliary cooling and condensing device and which is so arranged with respect to the main cooling system of the engine as to provide an efficient device for supplying additional water to the engine when required.

Another object of this invention is to provide the auxiliary coolingldevice with a reservoir or container which is normally air tight and its connections water sealed when the water level in the main cooling system of the engine is normal, but which will automatically release the required amount of water from the reservoir when the waterlevel in the main cooling system of the engine falls below normal to supply the deficiency.

Another object of this invention is to pro vide a device for the cooling system of an internal combustion engine for relieving the excess pressure and the consequent excess temperature within the water jacket and manifold of the engine.

Another object of this invention 'isthe provision of means for refrigerating the hot water by the explosive mixture of the engine and at the same time to utilize the heat units of the hot water for heating the explosive mixture.

A further object of this invention is the provision of means for supporting the auxiliary cooling device and connecting the same with the main cooling system of the engine at points whereby to efficiently attain the desired results. 7

A further object of this invention is to provide an auxiliary device which can be readily attached to any of the automobiles and their engines or to stationary gas engines now in use or which can be built in the above structure's during their course of construction.

These and other objects and advantages will more fully appear as the nature of the invention is more clearly understood from the following specification, the subject matter of the claims, and the views illustrated in the accompanying drawings, in which,

Figure 1 is a side view of the front portionoii an automobile, shown partly in section, showing one form of applying the invention in operative position upon an automobile.

Fig. 2 is a vertical transverse sectional view on line 22 of Fig. 1 looking in the direction of the arrow, showing the means which may be employed for adj ustably supporting the device if desired.

Referring to the drawings, 1 denotes the portion of the chassis or frame of the automobile, 2 the dash board, 3 the engine hood, 4L the radiator, and 5 the engine having its hot water hood or manifold 6 operatively connected with the upper portion of the radiator 4L by the hot water pipe 7 and also having the lower portion of its water jacket operatively connected with the lower portion of the radiator 4 by the cold water re.- turn pipe 8.

In the drawings I show means for adjustably supporting the device which consists in providing the oppositely disposed spaced pairs of supporting standards 9 secured upon the frame 1, each of the standards 9 being provided with the elongated slot 10 for adjustably receiving the threaded bolts 11 upon the shoulder 12 of the brackets 13 which are suitably secured upon the reservoir and condenser 14; at substantially diametrically opposite points, the threaded bolts 11 being retained in their adjusted positions by the nuts 15 screwthreaded upon the bolts 11 binding the standards 9 between the shoulders 12 of the brackets 13 and the nuts 15, so that the reservoir 14 may be elevated or lowered to substantially the positions shown in full lines and dotted lines in Fig. 1 in order to my invention.

hood or manifold 6 will now all suitably position the reservoir 14 with respect to the engine or to provide for the installing and the positioning of reservoirs of varying shapes and sizes.

The reservoir 14 shown in Fig. 1 is preferably positioned at a suitable point between the engine 5 and the dash board 2 and has its upper portion connected to the hot water hood or manifold 6 of the engine by the pipe 16-, preferably a flexible pipe, and

the bottom portion of the reservoir 14 is connected to the cold water union 17 leading into the water jacket of the engine by the pipe 18, also preferably a flexible pipe, or the connecting pipes 16 and 18 may be metal pipes having any suitable form of rotatable unions therein or may be continuous and unjointed pipes if desired. 7

I attain many advantageous results by he feature of the invention being that the reservoirs are connected by the pipe 16 to the hot water hood or manifold 6 at a point where the water is the hottest and where the upward flow of the hot water and steam is obstructed by the back pressure within the pipe 7 leading to the radiator 4 which back pressure is caused by the sudden cooling of the water within the pipe 7 so that there is created through the auxiliary cooling device a more complete thermosiphonage through the auxiliary cooling device to thereby relieve the excess pressure and the consequent excess temperature within the water jacket ofthe engine.

Another feature is that the reservoirs remain normally air tight and full of water and the pipe 16 water sealed so long as the water level in the main cooling system of the engine is at its normal height but as soon as the water'level in the engine falls sufficiently below its normal height to un seal the pipe 16, the air or steam within the freely pass through the pipe 16 and the upper portion of the reservoirs and thereby release a sulfi-- cient quantity of water from the reservoirs to supply the deficiency of water within the main cooling system of the engine through the pipe 18 to the water jacket of the en gine.

'A further feature resides in the fact of neeapee the reservoirs being air tight so that when the engine has been stopped for a sufficient length of time for the engine and the water in the main cooling system and the water in the auxiliary cooling system to have become cooled, the water in the reservoirs which I employ will contract and settle. to ward the bottoms thereof and thereby create a vacuum in the upper portions of the reservoirs, whereby upon the starting of the engine and the heating of the water the vacuum will accelerate the upward flow of the water and immediately establish circu lation through the auxiliary cooling system and when the water becomes sufliciently hot the water thereafter circulates through the auxiliary system by the thermosiphon created therein and independently of the regular cooling system of the engine.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is g 1. The combination with the water circulating means of an internal combustion engine including a water jacket and a hot water outlet and cool water inlet for said jacket, of a reservoir having flexible connections with said water outlet and inlet for the circulation of water through said reser voir, and means for mounting said reservoir for vertical adjustment with respect to the water jacket.

2. The combination with the water'circulating means of an internal combustion engine including a water jacket and a hot water outlet and cool water inlet for said jacket, of a reservoir independent of said water circulating system disposed at one side of the water jacket, flexible connections between the upper and lower portions of the reservoir and said water outlet and inlet, respectively, and means supporting said reservoir for vertical adjustment with, respect to said jacket.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JESSE D; LANGDON.
