Specification of Letters Patent.
Patented ree. is, 1ere.
To all whom t may concern.'
Be it known that I, ARTHUR O. DADY, a citizen of the United States, residing at New York, in the county of New 'York and State of New York, have invented a certain new and useful Improvement in Valves for Internal-Combustion Engines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specication.
rlhis invention relates to -improvements in valves for internal combustion engines, and is particularly concerned with hollow exhaust valves of the so-called mercury cooled type in which a small quantity of mercury held in the head of the valve is vaporized when the valve head becomes heated, the vapor being condensed upon the walls of the valve stem and returned to the valve head. In order to insure themost efcient cooling action in valves of this type it is necessary to provide means for quickly radiating the heat from the valve stem. Various expedients have been employed for this purpose,
and the objects of my invention are, rst, to
did
provide a radiator having intimate contact with the valve stem, whereby the resistance to the radiation or conduction of heat is reduced to a minimum; second, to provide a radiator adapted to be detachably connected with the valve stem; third, to provide a radiator of the class described which will not materially increase the weight of the valve. Further objects will appear as the description progresses, reference being had to the accompanying drawings, in whichlFi re 1 is a view artially in central longitu al section andp partially in elevation, of my improved valve; and Fig. .2 is an end elevation thereof lookin toward the radiator end of the valve.
imilar characters of reference refer to similar parts in the two views.
Referring to the drawin the reference` character 1 indicates a hoglllow valve stem having one end dared as shown at 2 and closed by a Vmetal disk 3, which is secured in place by brazing or in any other suitable manner, as indicated at 4. The opposlte end of the stem is provided with` a screw thread 5, the screw-threaded portion also being hollow as indicated by the' dotted lines. The radiator for my valve comprises a sleevelike member having an internally threaded bore 6 for receivingthe screw threads of the valve stem. Spaced longituf dinal ribs 7 extend from the sleeve member and provide elicient means for radiating the heat. The extreme end of the valve stem opposite the head is of course closed and the end of the radiator adjacent this end of the stem is provided with a plurality of diametrical slots 8, which are adapted to receive a cotter pin 9 that extends through a hole l0 in the closed end of the valve stem.
In practice I prefer to form the valve stem and head from steel or some of the steel alloys usually employed for this purpose, and to form theradiator from aluminum. Inasmuch as the co-eiiicient of expansion of aluminum is practically twice that of steel, when the valve stem and the radiator become heated the radiator will tend to expand away from the valve stem, whereby the intimate contact between the inner wall of the radiator and the valve stem will be partially destroyed, thereby increasing the resistance to the conduction of heat from the valve stem to the radiator. at the same time that lthe radiator increases in diameter, it likewise increases in length to a greater extent than does the threaded portion of the valve stem, and consequently the sides of the screw threads on the radiator are forced into intimate contact with the sides of the screw threads on the valve stem, and thereby maintain an intimate contact between the valve stem and the radiator. The screw threads upon the valve stem and the radiator, therefore, co-act to However,
between the two members.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. A valve comprising a stem, one end of which is provided with screw threads in combination with a radiator comprising a member having s aced ribs and a screw-threaded bore for receiving said screw-threaded stem, and means for locking said radiator sald stein, the metal of said radiator havlng a larger co eliicient of expansion than the metal of said stem, v
2. A valve comprising a hollow st em provided with screw threads 1n combmatwn icc iyeeefeir portion of seid stem, the metal of seid redietor having a larger co-eeient of expansion than the metal of said stem, and ineens for compensating for the dierences between the co-effioients of expansion of said metals.
in Witness whereof, hereunto subscribe my 7nime this 21st day of December9 A. D. 191
