ARTHUR O. DAIJY, OF NEW YORK, Y., ASSIGNOIC. TO PFANSTIEHL COMPANY, INQOR- PORATED, OENORTH CHICAGO, ILLINOIS, A CORPORATION OF NEW YORK.
VALVE AND MEANS FOR COOLING THE SAME.
Application filed January 2, 191a. Serial-No. 209,391.
To all whom it may concern:
Be it known that I, ARTHUR O. DADY, a citizen of the United States, residing at New York, in the countyjof New York and State of New York, have invented a certain new and useful Improvement in Valves and Means for Cooling the Same, of which the following is a-full, clear, concise, and exact description, reference being had to the accompanying drawings, forminga part of this specification.
This invention relates .to valves for internal combustion engines, and is particularly-concerned with valves of the so-called mercury cooled type, these valves being provided with hollow heads and stems which sions that it of-itselfdoes not constitute an eflicient heat radiating means and means I have heretofore been employed for increasing the radiating surfaces of the valve stems, but, so far as I am aware, these means were not carried by the valve stem and were not, therefore, in intimate contact with the The result.
Further objects will appear as the descripj tion of my inventionfprogresses, reference being had to the-accompanying drawings in which,
Figure l is a partial central longitudinal section through a hollow valve equipped with my improved radiating means which is shown in elevation; v
Fig. 2 is a plan view of one of the corru- Specification of Letters Patent.
Patented June 10, 1919.
gated disks which form a radiating element of my improved radiator; and
Fig. 3 shows a modified form of the corrugated disk.
Referring to the drawing, the reference character 0 indicates the hollow stem of a valve which comprises a hollow head 6 in communication with said stem. The stem 5 is provided with an extension 7 of reduced diameter on which is tightly fitted a brass or copper sleeve 8 having a shoulder 9 at one end thereof. In order to provide a large radiating surface without materially increasing the weight of the radiator I assemble a plurality of alternate fiat and radially corrugated disks 10 and 11 respectively upon the hollow tube, theperforations in these disksbeing of substantially the same diameter as the diameter of the tube 8 so as to offer but a little res'istance'to the conduction of heat from the tube to the radiating elements. If desired the inner edges of these disks may be sweated to the tube 8. Another method of securing the radiating elements on the tube is to merely sweat or otherwise secure the end disk 10 to the tube. A pin 12 extending through the end of the tube Sand the closed end ofthe valve stem prevents the radiatonfrom being displaced therefrom. A groove 13 formed between the end ;of the valve stem 5 and the collar 14 is intended to receive the means for actuating the valve. The disks 10 and 11 are preferably formed of copper or aluminum on account of their high heat conductivity,
but'may be made from other heat conducting materials' In Fig. 3 I have illustrated a modified form of corrugated disk in which the corrugations instead of extending radially, as in Figs. 1 and 2, are parallel to each other.
While I have described the preferred embodiment of my invention, it is to be understood that my invention is not limited to the details thereof, but is caprble of other modifications within the scope of the appended claims,
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 having a hollow head and a hollow stem communicating therewith in combination with a tube tightly fitting said -1 and a p r lity f perforated alternate flat and radially corrugated disks assembled on said tube and secured thereon.
2. A valve having a hollow stem in combination with a tube tightly fitting said stem, and a plurality of perforated alternate flat and corrugated disks assembled on said tube and secured thereon.
3. A valve having a hollow stem in combination with a tube tightly fitting said stem, and a plurality of perforated corrugated disks surrounding said tube and in, contact therewith. v
4:. A valve having a hollow stem in com} bination with a tube tightly fitting said stem, and 'a plurality of perforated disks -surrounding said tube and continuously contacting therewith.
5. A'valveh'aving a hollow stein in combination with 'a tube tightly fitting said stem, and a plurality of disks surrounding said tube and in contact therewith.
In witness whereof, I hereunto subscribe my name this 21st day of December, A. D. 1917.
. ARTHUR O. DADY.
