HYDROCARBON-MOTOR.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed April 14, 1915. Serial No.-21,314.

" of Detroit, Wayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is aspecification.'

This invention relates to hydrocarbon motors, and particularly to the cooling thereof. More specifically the invention relatest to a water circulation system for the cylinder water jackets of a hydrocarbon motor in which the temperature of the water is automatically controlled by. a thermostat or equivalent device. illustration of one embodiment of the invention a twelve cylinder motor having two cylinder blocks of six cylinders each arranged in V position is shown, but it will be understood that the invention is not lim-' ited to the exact form herein shown but may be modified in various ways without departing from the scope of the invention;

One of the objects of the invention is to provide a simple and practical automatic control for the temperatureof the water of the cooling system of a hydrocarbon motor.

0 Another object of the invention is to provide a cooling system for a hydrocarbon motor having two cylinder blocks, in which the temperature of the water will be ,auto.

matically controlled and will be uniform in the two cylinder blocks.

Another object of the invention is to provide a simple and novel pump mechanism and thermostat device fora hydrocarbon motor.

Another object of the invention is to provide a particularly advantageous-and novel arrangement 'of conduits and water circulation elements of a hydrocarbon motor.

Other objects of the invention will appear from the following description, taken with the drawings, which form apart'of this specification, and in which: i

As an Fig. 5 is a section through the pump mechanism taken longitudinally of the driving shaft, and substantially on the line 55 of Fig. 6;

Fig. 6 is a vertical section taken transversely of Figs. 1 and 5 substantially on the line 66 of Fig. 5;

Fig. 7 is a sectional view of another form of the pump and thermostat;

Fig. 8 is an end elevation of the pump and thermostat shown in Fig. 7

Fig. 9 is a sectional view of another form of thermostat unit; and

Fig. 10 is similar to Fig. 9 but showing a modified form of valve connection.

Referring to the drawings, 10 represents the motor base or crank case, in which is mounted the crank shaft 11 in suitable bearings 12. A pair of cylinder blocks 13 are mounted upon and secured to the crank case with the cylinder axes of the respective blocks in V relation. In the form shown,

as arranged vertically above the crank shaft. and driven thereby through chain mechanism 17 or other suitable gearing. The

usual piston 18 and connecting rod 19 are shown, and the intake pipes are represented at 20 and the exhaust pipes at 21.

.the cylinders are arranged approximately 60 degrees apart, the motor shown being 21.12 Inlet and exhaust valves Each of the cylinder blocks is provided with a water jacket lhaving an intake opening 22 arranged adjacent the middle of the block and preferably on the outer side thereof, as shown particularly in Fig. 3. It will be understood that the water jackets surrounding all of the cylinders of each block are inter-connectedso that they form practically a single water jacket around the entire block of cylinders. Each block is provided' with an outlet at either end, the front outlets indicated at 23 'and the rear outlets at 24. Radiator means 25 are suitably mounted at the front end of the motor andconduits or pipes 26 connecttheoutlets 23 of the cylinder block w-aterjacke'ts with said radiator means '25. 'At the rear end of the motor there are branch pipes 27 which lead from the outlets 24: to a bypass pipe or conduit 28. It will be understood that the radiator 25 may be of any suitable well-known construction adapted to cause a rapid radiation of the heat from the water passing downwardly through it. It is provided with an outlet pipe or conduit 29 which leads rearwardly to a conduit 30 with which the bypass pipe 28 also connects. Referring particularly to Figs. 1 and 1, it is seen'that the port opening 31 of the pipe 28 into the conduit 30 is arranged just below the opening 32 of the pipe 29 into said conduit 30. These openings are controlled by a valve 33 which may be moved in the conduit 30 by means of its stem 31 to cover and uncover the ports 31 and 32 above referred to. In the position shown in Fig. 1, the port 32 is practically closed and the port 31 is open, it being understood that the water entering the conduit 30 through the port 31 will pass upwardly through the valve 33. In Fig. l the valve 33 is in its lower position closing the port 31 and leaving the port 32 wide open. In this latter position of the valve the bypass conduit 28 is thrown out of action and the radiator means is in operation.

Referring particularly to Figs. 1 and 3, it will be seen that a pump mechanism 35 is arranged between the conduit 30 and the intak openings 22 of the two cylinder blocks. A pipe 36 forms acommunication between the pump mechanism 35 and the intake 22 of the right hand cylinder block in Fig. 3, and

a pipe 37 leads from the pump mechanism through the crank case to the intake 22 of the left hand cylinder block of said figure.

In the form of the invention shown, the pump mechanism comprises a suitable double pumpcasing 38 in which a pair of spaced impellers 39 are rotatably mounted. These impellers are probably best shown in Figs. 5 and 6 as are also their bearings -.t0 in the casing. The impellers are suitably driven from the motor crank shaft by means of a shaft 41 extending forwardly from the pump casing to the gearing at the front end of the motor. p

The pump casing 38, in addition to its connection with the cylinder blocks and crank case through the pipes 36 and 37 as above described, is also connected to the. conduit 30 by the tubular part 12 which forms a continuation of said conduit 30. It will be seen, therefore, that the conduit 30 forms a common intake for both pumps. It will be seen also that one of the pumps discharges into the pipe 36 and the other into pipe 37, but as both of them take the water from the conduit 30, the water passing to the two cylinder blocks is of the same temperature.

Referring to Fig. 6, the pump casing is enlarged somewhat at one side to form a continuation of the intake conduit 30, and the valve stem 31 extends upwardly into, this enlargedpart and is connected to a thermostatic unit 43 of any suitable construction. It may be in the form of an expansible metal or, as shown in'the form of a plaited tube containing an expansible liquid or gas whereby the valve 33 through its stem 31 is caused to change itsposition with relation to the openings 31 and 32 upon a change in temperature of the water passing through the conduit 30. A rack bar 11 is secured at the upper end of the unit 13, and its cylindrical upper end it forms a guide for the unit 13 and valve stem 31.. The thermostat unit and valve are adjusted or positioned by a small pinion 15 on a shaftlG engaging the teeth 17 of said rack. Said shaft 16 may be moved by the handle 18 arranged on the outside of the casing and a locking screw l9 secures the shaft.

It will be understood that the thermostatic unit 13 contracts with the cold and expands with the heat. Therefore, the valve 33 being set in the position shown in Fig. 1 when the motor is cold, if the motor is started and the pump thereby operated,- the cold water in the circulation system will pass through the water jackets of the cylinder blocks and out at the rear end through the. pipes 27 and 28, through the port 31 and the valve 33.

and flow over the thermostatic unit 13 and back to the pump. There will be practically no circulation from the front end of the cylinder blocks to the radiator because of theclosure of the port 32 by the valve As there is practically no radiation inthe pipe 28, the water in the system will soon begin to heat up and thus expand the thermostat 13. As the thermostat expands,'it moves the valve 33 downwardly and begins to cut off the port 31 and open the port 32. 1 In the normal operation of the motor the valve will probably remain near its lowest position, but this will of course vary with the effectiveness of the radiator means 25 due to atmospheric changes. The positioning device l5, 16, is useful in varying the tempeiaturedegree at which it-is desired to operate the motor. A drain cock 50 is provided adjacent the valve mechanism to assist in draining the water system.

Referring to the form of pump and thermostatic mechanismillustrated in Figs. 7 and 8, it will be seen that the pump is substantially the same as that illustrated in the other figures except that there is no enlargement for the thermostatic unit, the latter being arranged in a separate chamber below the pump. There is'a similar tubular part 12 to which is attached a casing 30 formed with achamber 30 in which is a horizontally arranged thermostatic unit. 13 connected to a valve stem 31 having valve 33 cooperating with port 31 and valve 33 and 29 communicating with ports 31 and 32 respectively are also shown 1n l lg. 4. For

cooperating with port 32*. The pipes 28 the purpose of holding the valve 53 closed as long as possible after starting the motor cold so that it will quickly heat up to normal temperature, the valves are so positioned that the water pressure against them tends to hold valv 33 open and valve 33 closed, thus by-passing the water until it is quite hot before the thermostat can act to expand and open the pipe leading from the radiator. Also, in the use of a thermostat which expands upon puncturing, the radiator port 32 will be opened or left open as the case may be, automatically in case of an accident to the thermostat.

In Fig. 9 a thermostat 4L3 'is used similar to that of Fig. 7, but the valves are differently arranged. J Where comparatively higher water pressures are used, or for other reasons, it is desirable to have the two valves balanced and interconnected. Thus the stem 84 is operatively connected through pin 84* and transverse slot M with a link 34 which link forms an interconnection between a balanced butterfly valve 33 controlling the passage 31 in the pipe 28 and a similar valve 33 controlling the passage 32 in the pipe 29. This link is so connected to the valves that while one is opened the other is closed and vice versa, and the thermostat connection is such that, as shown in full lines in Fig. 9, when the system is cold or the active element contracted, the valve 33 will be open and thevalve 33 closed, and vice versa. Since both valves are balanced the water pressure does not affect the opera 1 tion of the thermostat.

In Fig. 10 the thermostat is so connected to the valves that the latter may be independently and manually operated. In case of failure of proper operation of the thermostat or for any other reason it is desirable at times to positively open the valve 33 and hold it open to permit circulation of water through the radiator 25. Thus in Fig. 10 the connection from the element 43 to the link 34 is a yielding one, the slot 3 3 being formed in a sleeve 34' sliding on the link 3& and arranged between springs 34 and stops 3%. i It will be seen that the normal operation of the valves isthe same as in Fig. 9, but they may be manually operated independently of the thermostat, one or the other of the springs 34; yielding for the purpose. The valve is manually operated by a handle 33 secured to its stem 33 on the outside of the pipe 29 and a segment 33 permits of locking the valve in any desired position by means of the set screw 33.

Variousother forms of the invention may be devised and will fall within the terms of the claims, and I do not intend that my invention shall "be-limited to the exact constructions shown, these being by way of illustration only.
