HYDROCARBONMOTOR.

Specification of Letters Patent. v Patgntigfl Fig 29 1921,

Application filed August 8, 1917. SeriatNo. 185,218.

T 0 all whom it may concern:

Be it known that I, HAROLD D. CHL RCH, a citizen of the United States, and res dent of Detroit, \Vayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification.

This invention relates to motor vehicles and more particularly to apparatus for controlling the circulation of the acket water of the hydrocarbon motor. It has been proposed to provide motors of this type with a thermostatic valve to control the flow of hot water both from the motor to the radiator and also through aby-pass around the radiator. This invention relates to aparticular arrangement of the valve and its connections whereby the water is by-passed through a path of minimum length so that 1t heats quickly. The various features of the invention will be apparent from the description taken in conection with the drawings. in which i The single figure is a side elevation of a portion of a motor vehicle power plant, the thermostatic valve and the apparatus immediately connected thereto being shown in section.

As clearly shown in the drawing the water jacketed hydrocarbon motor 10 of any desired type has its jacket connected to the radiator 11 by means ofthe discharge conduit 12 which includes the detachable section 27. The bottom of the radiator is detachably connected with the circulating pump 13 by means of the cool water conduit 14. A by-pass 15 extends from the top of the water jacket to the intake of the circulating pump. In motor vehicle power plants as usually designed the hot water from the engine jacket is conducted to the top of the radiator and taken out at the bottom thereof and fed to the intake of the circulating pump which in turn discharges the water to a low part of the engine jacket. \Vhen starting the motor, especially in cool weather, it takes considerable time to warm up the engine so that it will operate efliciently. In addition to the cooling effect of the atmosphere the jacket water is also reduced in temperature because of itspassage through the radiator. In other words, the atmosphere and radiator tend to reduce the temperature of the jacket water while the en gine is attempting to increase it. In order to make it possible to warm up the motor more rapidly under these conditions the bypass 15 is provided and controlled together with the conduit 12 by means of a thermostatic valve 16.

One of the important features of the invention consists in locating this thermostatic valve at the top of the motor. As shown the The conduit 12 is connected to this end ofthe housing and the discharge of fluid into the same is regulated by the valve 22. This valve 22 is carried by a. slidable spindle 23 whichat its opposite end is connected to a .thermostat unit 21 of any desired construction. As shown the thermostat consists of a bellows construction filled with a suitable liquid, whereby the bellows is extended and contracted by changes in temperature. Intermediate the thermostat and the valve 22 is a valve 25 which is adapted to be moved to seat against the substantially semi-spherical part 26 arranged on the interior of the housing and opening into the by-pass 1 5. The distance between the valve seats on the members 21 and 26 is less than the distance between the valves 22 and 25 whereby when one valve is closed the other is open or if they are in an intermediate positionthen both valves are partially open. In this manner the discharge of water from the engine jackets into the hot water pipe 12 or by-pass 15 is controlled according to the temperature of the water. Vhen the temperature is low the thermostat is contracted and consequently' the valve 22 is closed so that the water is discharged from the top of the jacket down through the by-pass 15 to the pump. rises and the thermostat expands, the valve 22 is gradually opened and the valve 25 gradually closed. When the temperature of the water is at the desired pointthen the by-pass is entirely closed and the circulation of the jacket water is through the radiator in the usual manner.

With the thermostatic valve and its connections arranged as described, that is at the top of the water jacket or engine, it is apparent that the distance through which As the temperature of the water I -heat -in,its circulation whereby the motor will warm up very quickly. F urthermore' this combination and arrangement of the parts permits the removal of the radiator Without in any way disturbing the thermostat or the valves.

Although the embodiment of the inven tion has been described specifically it is apparent that many of the details may be varied without departing from the spirit of the invention.

Having thus described my invention, wha I claim and desire to secure by Letters Patent is 1. A hydrocarbon motor having an aperture in its top opening, from the water picket, a housing secured over said aperture with'its interior in communication with said water jacket through said aperture and hava passage leading to the return from the radiator, and a thermostatic valve within;

said housing controlling said passages.

' .2. A hydrocarbon motor having acylinder head, a housing secured directly-to said head,

the interior of said housing being in communication with the Water jacket of the head, two outlets from saidhousing, one be ing in communication with the upper part ing a discharge passage to the radiator and i of the radiator and the other with the return from the bottom of the radiator, and; a thermostatic valve controlling the flow of water through .said outlets.

-3. A hydro'carbon motor having a housing integral with the top wall thereof forming a chamber opening directly from the water jacket, .a water circulating pump, said housing having a discharge passage .to the radiator and a discharge passage to the water pump, anda thermostatic'valve within said housing controlling said passages.

In testimony whereof I iljl ature- I a g HAROLD D. C U CH.
