WILLIAM RITCHESON HAMM, OF SIMSBURY, CONNECTICUT.
COOLING JACKET.
SPECIFICATION forming part of Letters Patent No. 745,054., dated November 24, 1903.
Application filed March 24, 1903. SerialN0.14=9.327. (No model.)
To all whom, it may concern:
Be it known that I, WILLIAM RITCHESON HAMM, a citizen of the United States, and a resident of Simsbury, in the county of Hartford and State of Connecticut, have invented a new and Improved. Cooling-Jacket, of which the following is a full, clear, and exact description.
This invention relates to a cooling device intended especially for internal-combustion engines. It is especially applicable to automobile-engines, although it may be used in other connections with equally or nearly equally good results.
It comprises, briefly stated, a jacket proper combined with a number of radiating tubes, which are preferably, though not necessarily, arranged in two groups, one group extending longitudinally of and around the cylinder within the jacket and the other group projecting through and outwardly from the jacket.
This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is an end elevation of a cylinder having my invention applied thereto. Fig. 2 is a section on the line 2 2 of Fig. 1, and Fig. 3 is a detail view showing the preferred construction of the tubing.
a indicates the engine-cylinder, which may be of any form desired, provided with valves and valve-fittings, all of which will be understood. The jacket is preferably formed in two longitudinal sections b, fastened together, as indicated at b and 12 so that it is thus clamped on and around the sides and head of the cylinder.
0 indicates the tubes of the inner group, which are arranged longitudinally of the cylinder in cylindrical form around the same, their ends being open and the ends of the jacket being open, as indicated at b so that air-currents will have a free passage through the tubes. The tubes of the second group are indicated at d and have at their inner ends flanges d, these tubes passing through the jacket and extending out radially from the cylinder, the ends of the tubes d at the sides being bent forward and flared, as indicated, so as to increase. the circulation through the tubes. These tubes may be of regular form, as indicated in Figs. 1 and 2, or, if desired, they may be corrugated, as indicated at d in Fig. 3. The tubes (52 of the cylinder-head are not necessarily bent or turned as those at the sides. These tubes (1 are, like the tubes 0, open throughout, and the air drawn in at the outer ends of the tubes will pass through them into the jacket and fill the spaces surrounding the tubes 0.
In the use of the invention, especially in the automobile art, the bent ends cl of the tubes d are turned forward, so that as the vehicle is driven the inertia of the air causes a circulation through the tubes (1, as well as through the longitudinally-extending tubes 0. The air passing through the tubes d enters the jacket and fills the spaces surrounding the tubes 0 and then passes out through the tubes at the rear or head of the cylinder, as shown best in Fig. 2. This construction effects a far greater radiation of heat than in the usual ribbed or spurred construction, and, further, aside from the actual increase of radiation there are formed currents of air of more or less force which move around the cylinder- Walls in intimate contact therewith.
Various changes in the form, proportions, and minor details of my invention may he resortedto at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims, including the placing of the engine in any position and setting the bent tubes to correspond.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cooling-jacket, comprising a jacket proper, and a plurality of tubes arranged in groups, one group extending longitudinally of the jacket and opening at each end to the outer air, and a second group opening into and projecting from the jacket.
2. A cooling-jacket, comprising a jacket proper, and a plurality of tubes openinginto and projecting from the jacket, some of the tubes being on the periphery of the jacket while others are on the end wall of the same.
3. The combination with a cylinder, of a series of tubes arranged around the same and disposed longitudinally thereof, said tubes being open at each end, and means for holding the tubes in place, said means comprising a jacket embracing the tubes and cylinder and having openings in its ends corresponding with the open ends of the tubes.
41-. The combination with a cylinder, of a series of tubes extending longitudinally thereof around the same and having open ends to permit the circulation of air through them, a jacket inclosing' the tubes and having openings in its ends corresponding with the open ends of the tubes, and a second group of tubes extending through the jacket-walls outward beyond the same and open throughout their length.
5. The combination with a cylinder, of a series oftubes extendinglongitudinallythereof around the same and having open ends to permit the circulation of air through them, a jacket inclosing the tubes and having open ends corresponding with the open ends of the tubes, and a second group of tubes extending through the jacket-Walls outward beyond the same and open throughout their length, said tubes having bent and flared ends directed toward the front of the motor.
6. A cooling-jacket, comprising a jacket proper, and a plurality of tubes opening into the jacket and projecting therefrom, sundry of the tubes having bent and flared outer ends.
7. A cooling-jacket, comprising a jacket proper, and a plurality of tubes projecting from the periphery and one end wall of the jacket, said tubes openinginto the jacket and the tubes on the periphery of the jacket having flared outer ends.
8. The combination with a cylinder, of a group of longitudinally-extending tubes arranged around the outer walls of the cylinder, ajacket inclosing said tubes and having openings corresponding with the open ends of'the tubes, the jacket also having a Wall extending past the front end or head of the cylinder, and a second group of tubes passing through and projecting outward from the jacket at its sides and at said front wall or head.
9. The combination with a cylinder, of a group of longitudinally-extending tubes arranged around the outer walls of the cylinder, a jacket inclosing said tubes and having openings corresponding with the open ends of the tubes, the jacket also having a Wall extending past the front end or head of the cylinder, and a second group of tubes passing through and projecting outward from the jacket at its sides and at said front Wall or head, the tubes of the said additional group at the sides of the jacket being turned forwardly at their outer ends.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
YVILLIAM RITCHESON HAMM.
