INTERNAL-COMBUSTION-ENGINE CYLINDER.
Specification of Letters Patent.
Patented Au. 13,1912.
Application filed December 2, 1910. Serial No. 595,276.
To all 'LCILOWL it may concern 3e it known that I, I'IORATIO S. Snrrsoiv,
citizen of the United States, residing at Fairbury, in the county of Jefferson and State of Nebraska, have invented certain new and useful Improvements in Internal- Combustion-Engine Cylinders, of which the following is a specification. I
This invention relates to' internal combustion engines and has particular-reference to a peculiar form of cylinder adapted to effect the cooling of the same by a forced current of air.
.An object of this invention is to peculiarly form a cylinder for an explosive engine in which a current of air is introduced about the cylinder in such a manner as to confine the heat of the cylinder in the head of the same and to prevent the 'adiation of the heat to the lower part of the engine.
The invention has for another object to provide a cylinder with a spiral fin and a jacket engaging snugly over the fin to form a spiral channel or passage about the cylinder for the reception of an air current, the jacket and fin being so fo med as to introduce the air current at the base of the cylinder and exhaust the same at the head of the cylinder. In conjunction with this feature it is designed .to pass an air current about the cylinder from the base to the head thereof and to drive back and to exhaust the radiating heat from the head of the cylinder,
from the upper end of the cylinder, and to thereby offset the passage of the heat into the base of the cylinder and the crank case of the engine.
The invention further. contemplates a cylinder of this nature which is of simple construction so that the same can be readily manufactured and applied to internal combustion engines of the common type.
For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of an internal combustion engine having four cylinders, parts of the same being disclosed in section and showing the application of the improved cylinder thereto. Fig. 2 is a top plan view of the same. Fig. 3 is a detail perspective view of the improved cylinder, showing the jacket removed therefrom.
F ig. 4 is a transverse section on the line 4--1 of Fig. 1.
Corresponding and like parts are referred to in the following description and indicated'in all the views of the accompanying drawings by the same reference characters.
Referring to the drawings, particularly to F igs. 3 and 4, the reference numeral 10 designates a cylinder which is of the form of an elongatedhollow circular body closed at its upper end and provided in the usual manner with the valves 11. The upper end of the cylinder 10 is provided with an annular flange 12 which is of a diameter slightly greater than the cylinder 10. The cylinder 10 is provided with a base 13 snitably apertured as at 14: for the reception of scrcw-bolts, or the like, to hold the cylinder in position. The cylinder 1t) is provided. with a flange-15 having an annular boss or shoulder 16. A spiral fin 17 is formed about the cylinder 10 between the flanges 19 and 15, the spiral fin having a radius equal to the radius of the boss 15 and terminating at its ends in spaced relation from the flange 12 and the base 13. By terminating .the fin 17 in spaced relation from the flange 12 and the base 13, annular uninterrupted channels or passages are formed at the-opposite ends about the cylinder 10.
A detachable jacket 18 is fitted over the cylinder 10 and snugly receives the spiral fin 17 so as to close the passage about the edgesthcreof and provide a spiral channel extending the entire length of the cylinder 10. The lower end of the jacket 18 seats snugly against the shoulder 16 and,upon the flange 15. The shoulder 16 is adapted to seal the crevice between the'lower end of the jacket 18 and the flange l5.
An air inlet 19 is formed in one side of the jacket 18 and at its lower end registering with the lower annular channel about the cylinder 10. The upper end of the jacket 18 is provided with a central circular open- 7 is connected to the shaft 27 througlrthe interineshing beveled gears 80. The blower 29 is proyided with a feed pipe 31 havingbranch pipes 82-connecting with the inlets 19 in the lower ends of the jackets 18. It is thus seen by this construction that the rotat onof the crank shaft 24 of the engine operates the blower '29 to force a draft of air through the feed pipe 31 and branches 32 in the lower ends of the jackets 18. The air enters the inlet 19 of each of the jackets 18 and circulateswithin the annular channel at the lower end of the cylinder 10. The air is forced from the annular channel about the fin 17 and travels spirally about the cylinder 10. toward the head thereof. The cool air passing up about the cylinder 10 is adapted to force back the radiating heat from the head of the cylinder and exhaust the same through the outlet openings 22 in theupper end of the jacket 18.
An in portantfeature of this invention is in passing the cool air from the base to the head of the cylinder and in providing a distributing spiral fin to insure the passage of cool air about every portion of the cylinder 10 to effect the uniform cooling of the same and to thereby ofiset the radiation. of
the heat from the head of the cylinder.
After the explosion of the gas in the head of the cylinder, the head of the cylinder is the source from which the heat radiates, and by forcing; a cooling medium from the base of the cylinder to the head, the heat is directed toward the upperv end of the cylinder and confined at such point.
It will be 'understood that any suitable means may be employed for forcing the can rent of air into the lower end ofthe jacket 18 other than that disclosed inFigs. 1 and 2. Having thus described the invention What is claimed as new is In an explosive engine, an engine oylinder formed upon itsoouter surface with a spiral fin, the said cylinder being, provided exteriorly with'a flange at one end of the fin and with a-flange at the Ot'l1l,811d 0t.
the fin, the latter flange being of less diameter than the cylinder, the end helices of the fin being in a plane substantially parallel to the adjacent flanges and spaced there-front, a jacket fitted over the cylinder and its fin and having a head restingagainst the outer face of the second mentioned flange upon the engine cylinder and formed through its said head with openings located beyond the periphery of said flange and communicating with the annular air space between the head of the jacket and the adjacent end helix of the fin, the other end of thejacket fitting the periphery of the first n'ient-ioned flange upon the cylinder, and an air conduit opening;
through the-jacket at its last mentioned end.
. in testimony whereof, I: aliix my gnature in presence of two witnesses.
