ANDREW P. OLSON, OF CHICAGO, ILLINOIS.

RADIATOR.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed-May 20, 1913. Serial No. 768,745.

To all whom it may concern Be it known that I, ANDREW P. OLsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to radiators for explosive or gas engines and consists in the matters hereinafter described and then pointed out in the appended claims.

In the accompanying drawings illustrating a practical embod ment of my inventionFigure 1 is a side view of an explosive engine equipped with my invention; Fig. 2 is a front view in elevation of the parts of Fig. 1; Fig. 3 is a rear view in elevation of the radiator casing with the fan and water distributer omitted; Fig. 4 is a vertical sectional view on the" line 44 of Fig. 3; Fig. 5 is a side view in elevation of the fan and water distributer; Fig. 6 is a front wiew of the same, and Fig. 7 is a detail view.

In the drawings the reference numeral 10 indicates the cylinder of a gas or explosive engine of any type in which water-cooling is employed, it being understood that as many cylinders may be used as may be required, provided with water circulating outlet pipe 11 and inlet pipe 12 by which water is usually supplied to the water-j acket by a pump 13 in the supply pipe 14, the pipes 11 and 14 communicating respectively with the top and bottom of the radiator. The casing of the radiator is of sheet metal of any suitable size and shape having front, 15, rear, 15, sides, 15", to 15, and bottom, 15, walls. The casing orms a water-collectihg chamber and its lower portion provides a water reservoir or tank. The pipe 11 leads through the upper portion of the.

rear wall to an upper header 16 located in a. recess 17 formed by an inset 18 in the upper portion of the front wall of the radiator as shown in Figs. 2 and 4 and provided with a plurality of depending water-cooling or radiating tubes or ipes 19 uniting in a lower header 20 at t eir lower ends, the lower header being located at about'the center of a circular passage 21 formed in the front wall of the radiator. At the opening 21 and co-incident with its periphery a rearwardly extending cylindrical wall or partit1on 22 is secured which is slightly flared or enlarged toward its rearedge which extends within but circumferentially clears a corresponding circular passage 23 in the rear wall of the radiator as shown in Figs. 3 and 4 to leave an annular opening 24 between theperiphery of the passage and the partition. The cylindrical partition forms an intermediate drum which is of less diameter than the height and width of the body of the radiator so that passage is aflorded between the two, and the lower portion of the drum is provided with a door 25 hinged at 26 and having a suitable latch 27 to allow water to be poured into the lower interior portion of the radiator casing which forms the tank or reservoir with which the watersupply pipe 14 communicates. The space between the inner sides of the radiator casing and the drum 22 is provided with retarding or bafiie plates which may be arranged in any suitable manner, and in the practical form shown I provide upper and lower imperforate plates 28 and 29 respectively extendin outwardly from the drum toward the si es of the radiator body where they afford lateral passages 30 and 31 respectively, and also with upper and lower perforated lates 32 and 33 respectively which preferably are slightly dished at their centers, the plates 32 being intermediate the plates 28 and 29. Below the drum and extending across the depth of the radiator casing I place a pair of oppositely inclined bafile lates 34 and 35 which extend from poslte' sides of the radiator body anda 0rd opposite lateral passages 36 and 37 respectively, the latter leading into the water tank or reservoir formed by the lower portion of the casing. Where the radiator is associated with external engine cranking devices, such for example as the handle shown at 38, the lower ortion of the tank or reservoir is provided with a passage for the extended portion of the engine crank-shaft 39 formed by an arched partition or wall 40 which then dlvides the tank into opposite chambers which are connected. by a pipe 41 so that the water supply pipe '14 may draw from both. The pipe 41 is detachable so that the radiator can be assembled on the machine.

The fan 42 is provided with ,a shaft 43 supported in a suitable bearing 44 and driven in any suitable manner as for example'by a drive pulley 45 which is driven by a belt 46 from a pulley 47 on the engine shaft 39, the shaft being located co-axiall with the drum. The fan is provided wit a hollow hub 48 closed at the rear and having an axial circular opening 49 at its front to receive the free end of a pipe 50 secured to the lower header 20, the arrangement being such that the pipe and hub make a'suitable joint to allow the latter to freely revolve about the former. vided with a plurality of radial discharge pipes 51 preferably arranged tangentially on the hub and at a short distance from the fan blades so that air circulates between them, and each having a water-deflector plate 52 located in the hub at the opening to the pipe; as shown in Fig. 6 when the hub revolves in the direction of the feathered arrow the centrifugal action will cause the water to enter the pipes as shown by the featherless arrows. The pipes 51 extend radially to substantially the outer line of the fan blades where they connect with the interior of a peripheral annulus or circular rim formed by the ipe 53 which is divided into chambers, pre erably one for each radial pipe, by partitions 54 preferably placed intermediate the openings of adjacent pipes. Each chamber of the annular pipe 53 is provided slightly in the rear of its partition considered with reference to the direction of movement of the pipe with an air vent or supply opening 55, and adjacent its partition or closure 54 with a dis'chargeor exhaust opening 56 having a discharge pipe 57 which is curved. and extends through'the annular passage 24 into the interior of the radiator body and outside the drum. Each air vent 55 is provided with an air-intake or deflector plate preferably in the form of a forwardly directed outwardly flared funnel 58"hy which the air is directed under pressureint'o the correspondin chamber of the annular pipe 53 when the an revolves.

When the fan and water-circulating pump are operated water is drawn by the latter from the supply in the tank or reservoir in the lower portion of the bod of the radiatorand is circulated through t e water-jackets of the engine cylinders to the return pipe 11, header 16, cooling or radiating pipes 19, and lower header 20 from whence it to the hub 48 of the fan'and by centrifugal action through the pipes 5 1 to the chambers in the annular pipe 53 and out throu h the 'exhaust pipes 57 by which it is. (115- charged into the interior of the body of the radiator beyond or outside the drum. As the pipe 53 revolves with .the fan-in the dition of the feathered arrow in Fig. 5, atmospheric air is forced by the funnels 58 The hub is pro- EASSGS.

into the chambers of the pipe in advance of the water content of each chamber and is mixed with the water therein and dis-' charged with the water through the exhaust pipes 57 in a finely divided aerated spray around the drum 22, the air serving to cool the water. The particles of water pass over one or more of the bafile plates according to their respective points of exit from the pipes 57 and are further cooled in the passage back to the tank, the surplus air passing out of the interior of the body of the radiator through the annular opening 24. By the time the water reaches the tank its temperature is reduced to a point sufiicient to enable it to again act as a cooling medium for the engine cylinders.

While I prefer to employ radiating pipes, such for example as shown at 19, in front of the fan to initially reduce the temperature of the water coming from the waterjackets of the cylinders, I may dispense with ghein and lead the water directly into-the It frequently occurs. in cold weather that the circulation of the water by the construction described cools it below'a desirable temperature, and I may therefore arrange a cut-ofl whereby some or all of the water coming from the pipe 11 may be cut off from the revolving distributer and returned directly to the tank. For this purpose I may provide a bypass controlled by a suitable valve; this may be suitably accomplished by providing thelower header with an outlet pipe 59 leading to the tank or reservoir and a valve 60 which may be turned by its handle 61 to position to alternately open and close the pipes 50 and 59, either wholly or partially according to the requirements of any conditions of use. Where such by-pass is employed I preferably employ a pair' of pipes 59 whose communication with the header is controlled by the valve and whose lower ends are spread apart so as to brace and steady the header- Various changes may bemade without departing from the scope of my invention; for example, the revolving distributer may be used with or without a circulating pump as the centrifugal action of the distributer may besufiicient to draw the water from the tank, and with. or without the radiating 1 collecting chamber of the casing.
