PAUL DAIMLER, OF UNTERTRKHEIM, NEAR- STUTTGART, GERMANY, ASSIGNOR -T DAIMLER MOTOREN-GESELLSCHAFT, UNTERTRKHEIM, NEAR STUTTGART,
GERMANY'.4
To all whom it may concern:
Be it known that I, PAUL DAIMLER, a subject of the King of Wrtemberg, and resident of Untertrkheim, near Stuttgart, Kingdom of Wrtemberg, German Empire,
- ha've invented certain new and useful Improvements vin the Application of Cooling Apparatus for Motor-Vehicles, of which the following is anl exact specification.
The present invention relates to improvements in and in ,the 'application of cooling apparatus for motor vehicles and has for object to cool the driving parts `which become heated by friction. Hitherto only the cylinders of the explosion engines have been cooled by a water circulation system in which a radiator cools the water heated by contact with the cylinder, and it may be said that only those parts have been cooled which were heated directly by the combustion taking place in the engine.
It is advisable, for eliicient working of i motor-vehicles, to keep as cool 4as possible vthose parts which-become heated' by friction,
the change-speed gear and the crank casing being 'perhaps the most important in this respect. Of these two parts the crank casing is of course heated in a greater degree,
as, besides the heat due to friction, transmissiony of'heat takes place by conduction from the engine cylinder. Now according to this invention in order 'to utilize as much as possible the cooling action of the water cooled` by the radiator, the water is in the iirst place conveyed to a jacket surrounding' the change-speed gear casin and from this jacket the water, which has t en been only comparatively slightly heated, flows to a jacket surrounding the casing of the lower part of theengine. As the temperature of this part is greater, the cooling water becomes more highly heated but the diiference betweenI the temperature at this place and inthe cylinder jacket is so great that the water may still be used withsuccess for the cooling of the cylinder, By the'described simultaneous use of the water for the-cooling ofthe cylinders as well ash for the cooling of certain parts heatedv COOLING APPARATUS FOR MOTOR-VEHICLES.
Specification of Letters Patent. PatentedA July 25, 1911. Application filed November 5, 1907. Serial No. 400,812.
plication thereof isrepresented diagrammat-ically in the accompanying` drawing.
,The water cooled in the cooler a and passing from the latter from beneath, flows of the casing and from this jacket it passes through a second bent pipe g to the cooling jacket la, of the upper part of the casing. After the water has flowed around this casing and has cooled the'Qil and parts contained in the same it flows through a conduit z' into the cooling jacket of the lower part k of the crank casing of the engine, and then flows through a bent pipe Z into the cooling jacket of the upper part m offthis casing and is then drawn off by the circulation .pump a, which forces it through conduits o and p in the usual manner to the cooling acket of the cylinders g and r. From this cooling jacket the water returns through a pipe c into the radiatoror cooler a. The described transmission of the cooling water from the cooling jackets of the lower parts of the casings to the jacket of the upper parts of the casings through bent pipes situated eXt'e-" riorly is advisable in order not to endangerv ythe jointing between the individual parts of l. In combination, a 'heat engine andl change speed gear, a cooling radiator having an inlet for hot cooling medium and an outlet for cold cooling medium, cooling jacketing around said gear, a connection from the outlet of said radiator to said jacketing, cooling jacketing around the crank chamber of'said heat engine, a con- Il ection from said j acke'ting around said gear to thejacketing around the crank chamber of said heat engine, cooling jacketing around the cylinder of the heat engine, an externally jointed connection from the jacketing4 around the crank chamber of said heat engine to the jacketing around the cylinder and a connection from the jacketing around the cylinder to the inlet of said radiator.
2. In combination with the prime .nove'r of n automobile, a heat radiator, divided 'cooling jacketing around the change speed gear case, externally jointed piping joining the parts of said divided jacketing in series, piping leading from the radiator to the first in the series of cooling jackets for the change speed gear casing, a divided jacketing around the crank chamber, externally ointed piping joining in series the parts of said crank `chamber jacketing, a pipe joining the last in the series of jackets around the change speed gear case to the first in the series around the crank chamber, cooling jacketing around the Working cylinder, pipingv In Witness whereof I' have hereunto set' my hand in the presence of two Witnesses. PAUL DAIMLER.
