To all whom it may commuter Be it known that we, AldiERl (QARO, of Maywood, Cook county,'Illinois, inclines Bnnnmun, of Chicago; Cook county, lliiiiois both subjects of the Czar of Russia, have invented certain new and useful Improvements in lladiators for Automobiles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others "skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in radiators for automobiles or similar. motorpropelled vehicles for any connection with Water cooled devices in which it is desirable V to radiate the heat absorbed by the water in a radiator equipped with a multiplicity of radiating units, each having a relatively large radiating, surface compared to the cubic contents thereof and in which each radiating unit may -bc easily removed and replaced for purposes of repair and in which, furthermore, a broken unit may be removedand the openings, through .which the same. communicates with the body portions of the radiators, plugged to prevent leakage pending the insertion of a new or repaired unit in its place.

A further object of the invention is to provide a radiatorhaviug removable radiat ing units which is otherwise so constructed and arranged as to enable it to be easily as sembled and taken apart for purposes of repairand which is further so constructed and arranged as to provide a freer circulation of,

air around the radiator units in a-greater number of directions than is possible with the radiators .now generally employed for the same purpose,

Another object of the invention is to provide a radiator so constructed and arranged as to enable the circulation of air around the radiator units thereof to be easily and quickly increased and decreased according to the season, or severe changes of weather, to prevent the freezing of water in the radiator units and consequent iuj therete.

Specification of Letters Patent.

Application filed April 5, 1915. Serial No. 19,300.

Patented Dec. 26, 1916.

In the accompanying drawings illustrating a suitable embodiment of the invention: Figure 1- is a view in front elevation,

partly in vertical transverse section, of a radiator constructed in accordance with our nvention. Fig. 2--' is a vertical longitu- -dinal section of the same on the line 22 of 1-. Eig. -3 is a fragmentary de tail central vertical section showing the method of connecting the radiator units with the body portions of the radiator.

Fig. -4 is a view similar to Fig. 2-- showing how the circulation of air around the radiator units may be materially decreased when desired. Fig. 5-- is a dc tail horizontal section on the line 5-5 of Fig. 1.

The radiator comprises a base member 1 and cap member 2, each of which is adapted to contain a relatively large quantity of wa ter or other liquid adapted to absorb heat generated by the motor with which said parts are adapted to be connected by means of the pipes 3 and t shown in Fig. 2-. The liquid is introduced through the opening normally maintained closed by means of the plug 5. The said body portions 1 and 2 are provided contiguous to their ends with flanges 6 and 7, which are adapted to be bolted to similar or companion flanges 8 and 9 on the standards 10, and adapted to connect said body portions 1 and 2 firmly with each other and maintain them the requisite distance apart. The said standards 10 are skeleton structures which may be made of sheet metal or cast, the front and rearportions thereof presenting unbroken'walls, the side walls thereof being provided with large openings for the passage of air to the radiator units interposed between said standards and between the portionsl and 2 of the radiator. Mounted in these standards are foraminous protecting members 11 for preventing contact of the finger with the radiator units 12. Each of said radiator units 12 consists of a lielicallyv coiled pipe of relatively small diameter and having its end portions axially disposed relatively to the intermediate helically coiled portions, as clearly shown in Fig. 3. To one end of each pipe there is secured the member 13 of a union or similar coupling which is adapted to be connected to its companion member 14:


BEST AVAlLABLE COP rigidly mounted upon one of the opposed horizontal walls of the body portions 1 and I oi the radiat r respectively. lhe other end ol each pipr E threaded for connection with a l ilrdllllg or flange LL mounted in or upon the other of the said opposed horizon tal walls. The threaded members of the unions are preferably mounted upon a wall of the body portion of the radiator so that in the. meat of the removal of one of said units for purpose of repair. the said threaded member of said union thus opened may he cl sed by means of a suitable cap fitting the same, to be carried in the automobile, and the companion flange or bushing 14 may be closed by a suitable plug. These cap and plugs are omitted from illustration as being readily understood, by persons skilled in. the art. jam nut 1 t on the threaded member of each union prevents accidental loosening and leakage in a wellknoivn manner,

it will he observed that in our radiator all of the water passing to the motor, must during circulation. pass through the said radiator units 12 where it is exposed to the absorption of its heat y the air circulating around said units in a well-known manner. The standards 10 are not adapted to contain water or ei'insti tute duets for the passage of water from the upper member '2 t0 the lower member 1. of the radiator, it being well known that water in circulation will take the path of least resistance and in all cases where the parts corresponding to the standards 10 at our structure are hollow and adapted to permit the pas age of water in eiri'ailation. the water pas. parts to the substantial exclusion of its passage through those parts of the radiator corresponding to the radiator units of our structure, thus preventing such a complete absorption ol heat from the water as will prevent the same from attaining a temperature equalor exceeding the boiling point. The said radiator units are protected. against injury by means of the foraminous plates 17 mounted up n the trout and rear poi-lions of the structure and abutting against portions of the walls of the body portions 1 and L and against flanges il of the standards 10 and which are securely held in place y means of the bolts 17 passing through openings in the corners of said plates 13 and through the spare containing the radiator unit li v removing the nuts i roiu said l (llt' in! said plates or either of tin-m. may be easily removed or-replai-ed.

heating element, and a pin 'ality of radiating units connecting the two reservoirs and through which the liquid flows from the upper reservoir to the lower reservoir, said' units constituting the only passages through which the liquid can flow from the u per to the lower reservoir standards rigid y supporting the upper reservoir above the lower reservoir, large free air in ct openings in said standards and inwardly curved foraminous plates preventing free access to said units through said standards.
