INVERTED HEAD ENGINE WATER JACKET.

INVERTED-HEAD-ENGINE WATER-JACKET.
Application filed January 14., 1920.
T 0 all 10 7mm it may concern Be it known that I, ALDEN E. OsBoRN, a citizen of the United States of America, and a resident of New York, Bronx county, and State of New York, have invented certain new and useful Improvements in Inverted- Head-Engine i/Vater-Jackets, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.
This invention relates to an inverted head engine water jacket, and its object is to so.
construct the water jacket of an engine head of this character as to insure proper circulation of the water. Another object is to introduce the cooling water at the part of the head which is subjected to the maximum heating effect. Another object is to prevent the accumulation of sediment in the jacket. Still another object is to provide a jacket of this character from which the water may be drained when desired.
These and other objects of the invention will appear in the following specification in which 1 will. describe the-invention and the novel features of which will be set forth in the appended claims.
The drawing in this case is a sectional elevation of the upper part) of an inverted head sleeve valve engine with its water jacket made according to and embodying this invention.
In this drawing, 10 designates the cylinder wall of the engine and 11 the water jacket thereof. 12 is the inverted head and 13 a sleeve valve which moves between the sleeve wall and the head. 14 is the exhaust port of the engine which is controlled by a port 15 in the sleeve valve. 16 is a water outlet port leading to the upper part of the cylinder jacket 11.
The head is arranged to support piston rings 17 against which bears the sleeve valve. It also forms a combustion chamber 18. Between these parts is at water jacket 19 which extends outwardly over the cylinder water jacket.
20 is a conduit which leads from the water outlet 16 of the cylinder water jacket to the top of the water jacket. At the top of the head 12 at 21 and 22 is a tube which extends downwardly from this conduit to a point 23 near the lowest part of the water jacket of the head. 24: is the water outlet from the tube of the water jacket of the head.
In operation water is pumped into the Specification of Letters Patent.
Patented Sept. 28, 1920. Serial No. 351,344.
cylinder water jacket 11 at some convenient part thereof in the usual manner. It is discharged therefrom through the port 16 from which it is led to the lower part of the water jacket of the head by the conduit 20 and the tube 22, and discharged into the latter water jacket at the point 23. The water is discharged through the port 24. When the water jacket is drained, an outlet valve near the pump of the cylinder jacket is opened in the usual manner, and either the port 24: or a vent therefor is opened. All the water from the jacket of the head will be siphoned out through the tube 22 and conduit 20.
am aware that an attempt has been made to provide a structure capable of performing this desirable function, and has been disclosed in Patent No. 1,029,889, issued to Oskar Reissig, June 18th, 1912, but this arrangement fails to work because the lower part of the water jacket of the head becomes filled with sediment which clogs the end of the siphon. According to my invention, this objection is overcome and the water jacket of the head kept clear of sedi ment by using the tube which forms the inlet end of the siphon as the admission element of the .water to the engine jacket of the head. Admitting the circulating water at this point which is located near the exhaust port 1% not only introduces the water at the point Where the parts are subjected to the greatest amount of heat, but this arrangement keeps thejacket free of sediment so that the siphon is always available for use.
What I claim is:
1. in an internal combustion engine having a water jacketed cylinder and a water jacketed inverted head and means for automaticall draining the jacket of the inverted head when the cylinder water jacket is drained, comprising connecting means formthe only water connections between the cylinder and head water jackets, and therefore operating siphonically on the head jacket when the cylinder jacket is drained.
2. An internal combustion engine comprising a cylinder, a. water jacket therefor, an inverted head having a water jacket, atube arranged to admit water to the lower part of the water jacket of the head, connected with the upper part of the cylinder water jacket and forming the sole outlet therefrom whereby said cylinder Water jacket forms a part of a siphon by means of which the water may be drained from the jacket of the head into the jacket of the cylinder when the water is allowed to escape from the cylinder jacket.
3. An internal combustion engine comprising a cylinder having a water jacket and an exhaust port, a water jacketed inverted head, a sleeve valve arranged to move between said cylinder and said head and to control the exhaust port, a tube connected to admit water from the Water jacket of the cylinder to the lower part of the Water jacket of the head near the exhaust port, and providing a sole wate-rconnection between the cylinder jacket and head jacket and therefore forming part of a siphon by means of which the water may be drained from the jacket of the head into the jacket of the cylinder.
In witness whereof, I hereunto set my hand this 12th day of January, 1920.
A. E. OSBORN.
