RADIATOR.

Specification of Letters Patent. Patented June 1 7, 1919,

' Application filed March 28, 1918. Serial N 0. 225,163.

To (17Zwh0mz'tmag concern Be it known that I, HERBERT N. SEARLEs, a citizen of the United States, and a resident in the borough of Manhattan, city, county, and State of New York, have invented a new and useful Improvement in Radiators, of which the following is a specification, reference being had to the accompanying drawings.

While this present invention is not necessarily dependent upon that for which I made application for Letters Patent of the United States on the twenty fourth day of November, 1917, Serial No. 203,659, because its features may be embodied in many other forms of radiator, it may beneficiallyIbe1 emlave bodied certain of the elements disclosed in said former application.

It is the purpose of this invention to increase the efficiency of radiators and reduce I Generally stated, the improvements relate to means whereby the circulation of the cooling fluid and of the air within and through the radiator, is accelerated and maintained; alsoto means for reducingthe-cost of the pump system to compel circulation of the cooling liquid;

also to means'to'prevent clogging or sealing of the radiator by accumulations of air, water or foreign matter.

Referring to the drawings, Figure 1 is a vertical sectional view taken on the line 11 of Fig. 2, looking toward the right; Fig. 2 is an edgewise' elevation of the radiator, the central or pump section bemg broken away to show the interior construction.

In the drawings 2 represents a small tank or reservoir, usually but not necessarily present. 3 represents a pipe connection between the reservoir and the radiator. In the present instance the radiator is composed of five sections 4, 5, 6, 7 and 8, each comprising six water bearing tubes 9. Ateachend of the radiator are a series of what I call circulating chambers because in them the water in its circulation is in the first instance received from the motor, transferred from one section of tubes to the other and finally discharged from the radiator. Two of these chambers, 10 and 11, are what I call single chambers, one at the incoming and the other at the outgoing end, and four face.

of them, 12, 13, 14 and 15, are what I call double chambers. These several chambers are se arated from each other by water tight partitlons- 16. The water tubes 9 are made of very thin metal and flat in form so that their opposed Walls are separated by as small a distance (in the instance shown approximately one sixteenth of an inch) as practicable in order that the sheet of water flowing through them may be cooled as quickly as possible.

17 is a pump casing located in the center of the radiator. 18 is the upper surface of the pump cylinder and 19 the lower sur- I The pump is of the rotary type and is mounted upon the fan shaft 20 and is composed of two elements 21 and 21, both of them fast upon the shaft. 21 isa spiral part of the pump. It is located opposite the water passages 22 in the upper part 18 of the pump cylinder and to the right of the spiral portion of the pump are paddles or blades 23 located opposite the water passages 24 in the lower part 19 of the pump cylinder. These passages areequal in munber to, and preferably slightly larger in size than, the openings 22. a

25, 25, are fans. one on eithe side of the radiator and both fast on the shaft 20. which extends through the radiator, and is supported in suitable bearings, preferably provided. with stuffing boxes, lubricating packing, etc., as shown. The blades of these fans are set at such angles respectively that one of them acts as a blower discharging its blast upon and through the radiator and the other acts as a suction fan. which receives the air driven by the opposite fan and sucks or pulls it through the radiator. Thus the fans co-actively operating effect a strong current of air through the radiator at all times. 26 is a belt pulley or equivalent device, whereby the fan shaft carrying the fans andthe rotary pump with it is rotated at such speed as desired. 27, and 28, are vent cocks for the purpose of blowing ofi the water carrying chambers or passages of the radiator, being useful at times to relieve from airbubbles or to clear the radiator of dirt or other'objectionable deposits.

The operation is as follows:

The ends respectively of the tubes 9 open into the circulating chambers in such manner that as illustrated by the arrows, the heated water coming from the motor, or

from the reservoir 2, as the case may be, enters the single chamber 10, passes downwardly through the tubes 9 to the double chamber 14, for which there are six incoming and six outgoing tubes, and through that chamber and upwardly into the double chamber 12, in which there takes place the same flow of water, and from which the water passes downwardly to the pump casing 17. It is drawn into the pump through the openings 22 in the upper part 18 of the cylinder and thrust to the right by the spiral portion 21 of the pump (see Fig. 2) where under the influence of the blades 23 it is ejected from the pump cylinder through the openings 24 in the lower part 19 thereof into the downwardly extending tubes 9 and from them into the double chamber 15, from which it passes upwardly into the double chamber 13, from which it is discharged through the downwardly extending tubes 9 into the single chamber 11, from which it passes through the pipe 29 back again to the jacket of the motor.

It will be noted that a series of advantages are secured by this construction; that is to say, the employment of two fans, one to push and the other to pull the air through the radiator, avoids one of the specially objectionable features of motor radiators as now constructed, because their conjoint action is such that continuous and abundant flow of cool air through the radiator is maintained at all timesirrespective of whether the vehicle be moving against or away from the wind, or at an angle relative thereto; again, all deposits of dirt, dust and the like within the radiator due to the sluggish circulation of air therethrough which tend to reduce the cooling action of the air blast are avoided because the air currents are so violent that by no possibility can any such deposits remain upon the radiator. Also the location of the pump in the center of the radiator and driven at the speed of the fans enables me to use a much smaller pump than heretofore and likewise saves the space heretofore necessary for such pump, and its driving mechanism; furthermore, my construction is less expensive than pumps as heretofore constructed together with their driving mechanism because all I require is a few simple and inexpensive parts mounted upon the fan shaft which, owing to their construction,-are practically indestructible and do not require any repair or attention. The peculiar construction and method of 0peration of my new pump secures increased efiiciency when employed in combination with the two fans because all these elements are fast on the same shaft, hence they are all driven at the same speed; and both the fans and the pump embody the suction and delivery features, sometimes called the push and pull action, from which results the most efficient co-active operation between these parts. The pump compels the circulation of the cooling agent with unusual rapidity and the duplex air fans efiect the circulation of the air in unusual volume and speed to coincide with the increased flow of the liquid, thus securing, as I believe, better cooling thereof than has ever before been attained. Furthermore, since the pump is located in what may be called the centerof the water circulation without the skin friction due to additional piping, etc., the circulation is morefree and of larger volume than in apparatus as heretofore constructed; and lastly, the vents 27 and 28 afi'ord means whereby the interior of the radiator chambers andtubes may be kept clean, just as the violence of the air blasts keeps all its exterior surface clean.

It will be obvious to those whoare familiar with such matters that modifications may be made in the details of construction and yet the essentials of the invention be utilized. I therefore do not limit myself to the details described and shown.

I claim:

1. A radiator having a series of connecting circulatory chambers, a fan shaft located at about its medial part which projects through the radiator, a fan fast on the shaft on one side of the radiator adapted to act a blower, another fan fast on the shaft on the other side of the radiator adapted to act as a suction fan, a pump embodying a fixed cylindrical casing, a spiral suction section and a bladed discharge section, both of which sections are fast on the fan shaft, an intake water passage adapted to convey water to the pump, a discharge water passage adapted to convey water from the pump',"" and means to rotate the shaft.

2. A radiator having a series of connecting circulatory chambers, a fan shaft located at or near its medial part which projects through the radiator, a fan fast on the shaft on one side of the radiator adapted to act as a blower, another fan fast on the shaft on the other side of the radiator adapted to act as a suction fan, a pump for water circulation embodying a fixed cylindrical casing having intake and discharge water passages at opposite ends, the discharge having greater area than the intake, at spirally arranged part opposite the intake and propelling blades opposite the discharge, both fast on the fan shaft, and means to rotate the shaft. 7

In testimony whereof I have signed my name to this specification. 4
