DEVICE FOR EFFECTING-THEBADIATION OF HEAT.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed February 15,1904. Renewed ljeceniber 27, 1905. Serial Ho. 298,500.

To all whom it may concern:

Be it known that I, SCHUYLER W. ZENT, a citizen of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented certain new and useful Improvements in Devices for Efiecting the Radiation of Heat, of which the following'is a specification.

My invention relates to a method for effecting the rapid radiation of heat from objects exposed to a hi h temperature, and especially to reducin t e temperature of internal-combustion cy' ders.

The object of my invention is to provide means for the reduction of such temperature that will combine lightness of weight with effectiveness. I accomplish this result by means of heat-conducting fins, which are attached to and radiate from the outside surface of the cylinder.

In the drawings which form apart of this specification, Figure 1 is a section of the surface of a cylinder, showing a number of my heat-radiating fins in position. Fig. 2 is a section of Fig. 1 on line X X. Fig. 3 is also a section of the cylinder, showing a fin and corking-strip before the fin has been permanently secured in the cylinder. Fig. 4 is a section of a metal sheet, showing ragged edges D on the fins; and Fig. 5 is a trans' verse section of the cylinder.

A represents the dovetailed grooves which are madein the circumference of the cylinder. I ext end these dovetailed grooves longitudinally of the cylinder; but should I desire I may extend them completely around the cylinder, and particularly are these methods applicable to the head of the cylinder.

B is the fin, which is secured in A. These fins are preferably made in metal sheets out of a flat piece of metal sawed at the distance desired, as shown in Fig. 4. This sawingis done in such manner as to leave'the edges of the fins rough or corrugated and extends to about the outside surface of the cylinder. I also groove the sides of these fins by ress' cutting, rolling, or any other esirab e method. By having these fins roughened on the edges and grooved on the sides I greatly increase their radiating-surface.

C is a strip of narrow heat-conducting metal, which is placed alongside the lower ends of the fins in aperture A.

' To apply my invention to the cy der, I first make the proper groove A in the cylinder. I then place my sheet of heat-conducting metal, sawed as above described, in the a erture A, one end being in the groove and t e other radiating from the cylinder. I then place the heat-conducting metal strip C in the aperture A alongside the lower end of B, as shown in the first fin in 5. I then cork, or tamp C down securely, and causes the groove A to be entirely filled, thus holding fin B securely in A, as shown in second fin in Fig. 5. I twist the fins, as shownin Figs. .1 and 2 and in the third fin in 5, to give more free circulation to the air. As the cylinder becomes heated the fins in contact therewith receive a portion of said heat and radiate it into the surrounding atmosphere, While I may have the aperture A any desirable shape, Ifind that by having it as shown the heat radiation is materially increased.

Having fully described my invention, what I claim asnew, and desire to secure by Letters Patent, is-

1. In a device for effecting the radiation of heat, the combination with a surface subject to heat effects,having grooves which are undercut in their inner portions, of heat-radiating members seated in said grooves in continuation along the length of said grooves, and projecting freely yond the surface aforesaid, and independent strips tamped or forced into one side ofsaid grooves alongside the heat-radiating members which press the latter into the opposite undercut portions of the grooves.

2. In a device for effecting the radiation of heat, the combination with a surface, subject to heatefiects, having undercut grooves, of

heat-radiating fins twisted at their base and seated in said grooves and rojecting from the surface aforesaid, and ependent strips tamped or forced into one side of said coves alongside the-heat-radiating fins whi press the latter into the o posite undercut portions of the grooves and t ves fill the remaininglllindercut port-ions of the grooves.

testimony whereof I hereuntoaflix my signature in the presence of two witn.
