RADIATOB FOR INTERNAL-COMBUSTION ENGINES.

Application filed August 25, 1919. Serial No. 319,797.

To alt 'zchom it may concern:

lie it known that l, CLEMENT G. BRAN- s'rnuron, a citizen of the United States, residing at Bushnell, in the county of Mcllonough and State oi? lllinois, have invented certain new and useful improvements in Radiators for Internal- Combustion Enines; and it do hereby declare that the following is a full, clear, and exact description oi? the invention, which will enable others skilled in the art to which it appertains to make and use the same.

his invention relates to radiators for intei. a1 combustion engines. It relates more particularly to a radiator for an engine of the tractor type or "for other heavy duty.

in object oi my -vention is the provision of a new type of radiator for internal coinbustion engines having a novel arrangement for cooling.

Another object of the invention is to pro- "ide a radiator of a form in which the cylinders of the on e can lie. immersed in water, such radiator being supplied with a much larger bulk of 'atcr than customarily used, air-conducting tubes or pipes extending through the water for cooling purposes.

In addition to the above objects the invention relates to certa n details of construetion that will be pointed out herein, it being understood that what is shown is only one embodiment of the invention, sl it changes being possible without departing irom the spirit and intent ot the in vention.

To the end that the device may be understood in its entirety, l have furnished the acco panying drai 'ing wherein- Figure l is the front elevation of my radiator, showing two engine cylinders projecting fron'i its front face.

Figure 2 is a longitudinal sectional elevat on of the radiator showing one of the cylin ders.

Figure 3 is an enlarged detail, in longitudinal section, of parts shown in Figure 2.

Figure lshows in perspective certain details of construction of the radiator, and

Figure 5 is enlarged. detail of one end of a cylinder and the means for mounting it water-tight in a wall of the radiator.

iii represents two frame portions of the tractor or other type of vehicle (not shown) between which is mounted a receptacle or pan B for water, .the same being provided with longitudinal flanges C to rest upon said frame portions and bolted thereto in any suitable manner. DD represents two cylinders as a part of an engine, whose ends ex tend through the front and rear walls of the said receptacle Band secured therein in some such manner as is now to be described. TY

ihe front end or the cylinder ES provided with a flange abutting against the "front all oil? the receptacle, adjacent surfaces or" the flange and wall having annular grooves to receive a packing ring F to provide a water-tight joint. (51G are the heads of the cylinders, from each of which may extend the exhaust and intake manifolds H and J respectively. K represents a series of bolts passing through the flange of the head, the flange E and the wall of the receptacle se curing the whole firmly together, wiile L represents a packing ring let into grooves in the adjacent surfaces of the head G and flange E in order to provide a gas-tight oint. l

The rear ends of the cylinders are preier- :rbly reduced in diameter as in Figure 5 where they pass through the radiator wall B and the outer surface of said wall is provided with a recess M to receive a packing ring N, as clearly shown in this figure, there being aplate or ring 0 bolted to the wall and adapted to compress the packng ring N and force it against the cylinder wall whereby to make an entirely watertight joint. 7

PP represents two flanges extending from the under side of the receptacle B adapted to receive between them a saddle-block Q, clearly shown in Figure i, said block being secured in any usual manner to the spring indicated at R, a pin S serving to secure the flanges P and the block Q in pivotal manner. As clearly shown in Figures 2, 3 and 4;, the receptacle B of the radiatoris provided with an inwardly projecting flange at its top edge denoted at T. U is a box preferably of sheet iron having an inwardly directed flange V extending around its lower edge, which rests upon and is secured to the flange T, there being interposed between the two flanges a gasket W in order to form a tight joint. The said box is constructed so as to be entirely eater-tight and is provided at its top with a wall 3. a indicates a series of vertical tubes or pipes opening through this said wall and through the bottom of the receptacle B, the ends of the pipes or tubes beingsuitably turned over or swedged at their ends to make a water-tight oh. 5 indicates an angle bar at each corner of the box to properly brace it, their lower ends being firmly bolted to the receptacle B, as indicated in Figures 1 and 2. 6 is a hood covering the top of the re diator for carrying away exhaust gases and steam, the described exhaust manifold H being extended into said hood in the usual manner and perforated at 7, Figure 2.

S is a drain cock let into the bottom of the receptacle B by which water may be drained from the latter if desired. The receptacle B and the described. box is filled with water to a considerable height, it being noted that the cylinders D are immersed in the water. It is further observed that some of the pipes or tubes are disposed each side of the cylinders and between them and provide air passages from beneath the radiator up through the water and out of the hood 6 for cooling purposes, strong draft being induced through the pipe due to the exhaust pipe H. The number of tubes or pipes may be as great as desired, this being possible by increasing the size of the radiator receptacle and box, or other arrangements of the pipes may be made for the purpose.

The top wall 3 of the radiator box is perforated at c for permitting steam to escape into the hood, loss of water by evaporation or steaming being made up by the use of a filler cap 9, through which water may be introduced into the radiator.

The very large surface of the box exposed to the air, together with the surfaces exposed by the flues, act to keep the water properly cooled, even though the cylinders are emersed in the water. As constructed,

my radiator is thoroughly strong and rigid and therefore cannot easily be damaged even under the most severe usage in the field. I have neither shown nor described the igni tion system or any of the other parts of the engine, since these do not enter into the present invention, which relates wholly to a radiator and to a radiator having engine cylinders therein.

The sheet iron box is preferably employed because it provides thin. walls for quicker radiation, in addition to the fact that it is much lighter than those of heavy cast or wrought metal.

I claim:

1. In a motor vehicle, the combination with theengine cylinders thereof, of cooling means therefor comprising a vessel having end walls in which the respective heads of said cylinders are sealed, a cooling fluid in said vessel, vertical cooling pipes extending from the top to the bottom of said vessel on each side of each cylinder, an exhaust hood secured to the top of said. vessel, and an exhaust pipe extending into said hood for causing a circulation of air through said pipes.

2. In a motor vehicle, the combination with the engine cylinders thereof, of a cooling radiator therefor comprising closed vessel for supporting said cylinders with the ends of said cylinders sealed in the end walls thereof, a plurality of vertical cooling pipes on each side of each cylinder, said pipes extending through the top and bottom walls of said vessel, a cooling fluid in said vessel, and means for inducing an air draft through said pipes for cooling said fluid.

In testimony whereof I affix my signature in presence of two witnesses.

CLEMENT G. BRANSTRATOR.
