Specification of Letters Patent,

Patented June 4, i912 Applicetion filed May 20, 1907. Serial No. 374,664.

T0 at; whom is may concern:

it known that I, RUSSELL Hum; a citizen of the United States, and resident of Detroit, lVeyne county, State ofhlichigan, have invented certain new. and useful Improvements in. 'WatenCooling Systems for Hydrocarbon-Engines, of which the: follow ingis s specification.

The present invention relates to improvements in the cooling systemsv for the explosive engines of motor vehicles and has for its object: to provide a system, the parts of which shall be compactly arranged and so relatedas to secure a more cfiective coolting action then has been possible with the systems heretofore proposed.

A further ob ectof the invention is to 7 provide aradiator for such 21 cooling system I which shall be very durable and which will provide a maximum amount of radiating surfacewithout undesirably increasing the size or weight of the device.

In the accompanying drawings, Figure. l is Ta diagrammatic view of a cooling system constructed in accordance with the present invention and applied to an engine having two explosive chambers; Fig; 2 is a front elevation and partial section of the radiator; Fig; 3 is a vertical sectional View through the I'EtdlfliOL,

Referring to the drawings, 1 designates a pump of any'suitablc construction by which when. the engine is in operation, water is circulated through the cooling system, said pump being connected by a pipe 2 with a supply tank 3. From the pump 1 he water is forced through a governor 4% into apipe 5 which is connected with the inlet pipe 6 0f the radiator which W1ll be more particularly described herclnafter. The outlet, from the radiator is connected through a pipe 7 with the waterhjackets of the engine cylinders 8 and the latter areconnectedthrough s pipe 9 with a supplemental tank. 10 which is in turn. connected wlththe tank 3, as will be herematter more particua larly described.

It will he not-iced that to the present invention the radiator is arranged between the pump and the water jackets)? the engine cylinders ind thereby the pump is caused to positively forcethe water through the radiator rind also tofprovide a mesiinnnr pressure Wliililll the governor 4.

This governor is similar connection with wvater into the pipe separation of the steam andwa ter, a bafiie 17 is arranged within the tank preferably of the character shown in my prior application. Serial No. 282,844. l

Theradiator comprises a' plurality of series of horizontally arranged tubes 11 each having a relatively large number of radially projecting fins; and said tubes are so arranged and connected that a maximum amount of radiating surface is provided. As shown there are four tubes 11 in each series and till? inlet pipe 6 is connected directly with the upper series of said tubes through a manifold 12 At their opposite ends said upper series of tubes 11 are con nected by a junction box 13 with thetubes of the next lower series and the latter in turn are connected at their other ends,

the tubes or". the

third series. This connection of the series of tubes alternately at opposite sides of the radiator causes the water to circulate back and forth through all of the series of tubes before reaching the radiator discharge oub st or pipe 7.

. The heated water passing through the pipe 9 from the'jackcts of the engine cylinders enters the supplemental tank 10 at a point above the water line therein. \Vithin said supplemental tank is arranged a strainer let and said tank is also provided with an overflow pipe which extends therefrom along the outside ofthe radiator to the lower end thereof, this discharge opening being indicated at 16. The whiter entering the. tank at 10 sometimes contains considerable steam and the latter separates in said chamber from the water and escapes through the pipe 15 to the atmosphere. To prevent splashing-or the passage. of 1 5, and to assistin the with the pipe9. The upper end of the tank 10 is closed by a suitable removable cap -18. The water in the tank 10, 113mm. which the steam has been separated as above described,

10 in line bye passes to the lower tank 3 through two pipes 19, 20,. extending along opposite sides of theradietcr. The pipe 19. empties directly-into the tank: 3, while-the pipe 20 is connected with the outlet casting 21 to which the-punip supply-pine] 2 is connected.

A suitable strainer 22 is emsee within the tank 3' at the entrance thi thief-pipe 2.

The radiator is also provided with a vent 23 which connects pipes 6 and 9, the latter being as before described, in communication with the atmosphere through the supplemental tank 10 and operflow pipe 15.

In order that the entire system may be drained when desired, a drain cock 24 is provided in the pipe 2 and the latter is connected through a branch 25 with the lowest point in the pipe 7, The pipes 23 and 25 are of such small diameter that they do not materially impair the circulation of water through the system. a

It will be noticed that by this invention all of the parts of the system are compactly arranged, the radiator being mounted on the main supply tank 3 and the steam separator or supplemental tank 10 being supported by and forming part of the radiator. By this arrangement it is possible to effect a material saving both as regards the weight of the parts and the cost of manufacturing the same. Itwill ,be noticed that when in use there is a circulation of water through every partof the system, that is, the water circulates through both the main and sup? plemental tanks as well as the radiator and several pipes and the use of stand pipes or storage reservoirs, such as have heretofore been commonly employed is avoided.

Having thus described my invention what I claim is, a

-1. The combination with the water jacketof an engine of the class described, of two tanks arranged one above the other, a radiator between said tanks, a pump, aconduit from the water jacket to the upper reser-- voir, and a conduit leading from the upper reservoir to the lower reservoir, -for thepurpose set forth.

2. The combination of a Water jacket surrounding the cylinder of a motor vehicle engine, a tank, a conduit connecting the cylinder jacket and tank, an overflow pipecommunicating with the upper portion of the tank, and a baifle arranged in the tank opposite the discharge opening of said conduit, for assisting in condensing the steam contained in the water entering the tank from the cylinder jacket. I

In testimony whereof I aflix my signa ture in presence of two witnesses.
