MOT-OB CAR COMPANY 0F DETROIT, SMICHIGAN, A CORPORATIONOF MICHIGAN.

m'rmnn-oonnusrroiv ENGINE.

Be it known that I, Annual) Moonnousn,

v a citizen of the United States, and resident.

of Detroit, Wayne County, State of Mich.- igan,'have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines and particularly to the water cooling system thereof.

One of the objects of the present invention is the elimination of outside piping as .much as possible and the consequent simplification of theconstruction.

Another object of the invention is to prowater through the engine jackets with a thermostat at the outlet of the jacket and a ,short inside by-pass from the thermostat tothe intake side of the pump, so that the pump will-be low enoughto be primed at all times and yet close enough to the ther- -mostat to permit a short pipeconnection therefrom to the pump. Another object is to provide a combination side cover and distributing conduit for the cylinder water jacket, thus simplifying and improving the construction. Other objects of the invention will appear from the following description taken in connection with the drawings, which form a part of this specification, and in which:

Fig. 1 is a side elevation of an engine and radiator embodying the invention;

Fig. 2 is an enlarged section of one end of the cylinder block shown in Fig. 1;

Fig. 3 is a horizontal section substantiall on the line 33 ofFig. '2', extending the fu 1 -length of the block; s

Fig. 4 is a fra entary. vertical section on the line 4-4 0 Fig. 3; and

Fig. 5 is atransv'erse vertical section on the line 55 of Fig. 2.

Referring to the drawings 10 represents generally an internal combustion engine preferably of the motor-vehicle type and 11 r is a radiator shown as mounted at the front end of the engine. A fan 12 is mounted just back of the radiator for the purpose of increasing the circulationof air through the Application filed July 1,

the engine. The cylinder block is water jacketed around its sides and on top as shown particularly in the various" detailed views. This cylinder water jacket is indicated generally by the numeral 16; It is open at one side as shown at17 and a cover 18 is secured over the opening as by a series of screws-19.

, This cover will be hereinafter more particularly described.

The cylinder block is preferably divided horizontally along the line 20 shown in. the various figures so that there is the cylinder block proper and a cylinder head. The cylinder head is hereinafter'designated as 21 and the water jacket 16 extends into it as shown particularly in Fig. 2, the jacket'of the cylinder block proper and the separable cylinder head being connected by various vertiv cal openings such as' 22 shown in Fig. 2. Thus the water that is fed to the lower part of the cylinder jacket will flow through the openings 22 into the jacket of the cylinder head. The detachable head issecured in 4 place-by a series of bolts 2'1 At one end of the cylinder block'the castmg is formed with a compartment 23 with a large opening 24 therein, see Figs. 2 and 3. A pump unit 25 is adapted to be-inimpeller 28 on a shaft 29, the casing having openings 30 at its inner side .so that the water may be drawn in by the impeller and forced radially outwa'rdl into Z the com partment 23 above described. A bracket 31 extends from the pump casingoutwardly to form. a bearing 32' forthe extended end of the shaft 29 and the fan 12-above.de scribed is mountedon the end of said shaft.

A belt 33 may beconnected to any suitable rotating part of the engine for drivingthe fan and pump. j

There is a connection from the lower part of the radiator 11 to the intake side of the pump and this is shown as a pipe 34 which connects with a conduit or passage 35- leading to the openings 30 to the pump impeller. Thus the operation of the pump will draw the water from the lower part of the radiator and force it into the compartment or chamber 23 hereinabove described.

The compartment 23 has an' opening or I port 36 leading outwardly at the side of the cylinder block at the front end-thereof ad-.

jacent the side opening 17 and the cover 18 above referred to extends over this port as shown particularly in Fig. 3. In Fig. 2 the however, to prevent the, flow of cooling water being directed wholly against the I front cylinder the cover 18 is made in the .form of a distributing conduit.

It comprises an outside imperforate plate 37 and an inside plate 38 separated from it, thus forming an elongated conduit. The inner plate 38 is arranged to leave an opening 39 opposite the ,port 36' and it is provided with a series of ports or openings 40 along its lower part so that'the water will be some what evenly distributed to the various parts of the cylinder jacket.

The jacketed part of the cylinder head 21 overhangs the front end of the cylinder block immediately above thepump compartment and a thermostat 41 is mounted in, this overhanging part of the cylinder head jacket and is arranged to contrtil a double valve v 42-43. These valves control the outlet from the jacket. The valve 42 controls a port 44 and the valve 43 controls a port 45, bothof which ports lead from the water jacket. A passage 46 from the port 44 leads to anins1de pipe or conduit 47 which passes downwardly throughthe water jacket 16 to the Intake side of the pump and from thence through the pump and the port 36 and coverconduit 18 to the lower part of the cylinder water jacket. I with a pipe ,48 which leads to the upper part of the radiator 11 as shown in Fig. 1.

The action of the thermostat is as follows: When the engine is cold the thermostat 41 1s 1n its contracted state as shown in Fig. 2 and the'port 44 is open and the port '45 is closed. The water is circulated through the pump and the water jacket and upwardly through the port 44.; thence it will pass.

through the'passage 46 and the by-pass 47 back to the intake side of the pump and through the compartment- 23 and port 36 to the cylinder water jacket, where the circula- 'tion continues. As soon as the water heats up by the. operation of the engine the thermostat expandsand closes theport 44 and slmultaneously opens the port 45. This closes the by-pass to the pump and the water passes upwardly through the passage 48 to the top of the radiator 11. It'then passes downwardly through the radiator and is cooled and then is drawn up through the 34 and the passage 35 to the pump p1 e "which forces it into the compartment 23 through the port 36 and opening 39 into the The port 45communicates then to the forward part of that jacket.

around the thermostat where the-circulation continues as before described. 1 v
