To all whom it may concern:

Be it knownathat I, FRIEDRICH JOBANN Di'rmon: Hi'JLuNoHonsT, a subject of the Emperor of German of 190. Blythe Road, West-.Kensin ton ark, London, in the lesex, England, have invented a new and useful Improvement in Radiators This invention relatesto improvements in the water that is circulated overheated. v

The invention has more particular referwhicihan air propelling fan is combined with an annular chamber through which the heated water from the engines is caused to circulate and be cooled prior to its return thereto for further use.

The object of the present invention'is to provide additional cooling spaces or passages surrounding the airropelhng fan in combination with means or conductin the curor other parts to be cooled. r

'The invention consists essentially in'prov'idin radiators or coolers of the kind reto with a secondary cooling chamber concentric .with the annular chamber surrounding theair-propellin r fan, supplemental cooling spaces disposet at the trout and back of the radiator; intercommunicatiug pipes or connections between said annular tal coolin spaces; and a series of short pipes or ducts, leading from the space between the two annular chambers through one' of the supplemental cooling spaces, by which the air is directed about the parts to be cooled.

In order that the invention may be more readily understood I will describe the same in rel'erence to the accompanying drawings which are inlllustration of my invention, Figure'l being a front elevation of a radiator or cooler constructed in accordance with my improvements, the right.- hand' half of the figure .heing in section or broken away for the sake of (':learness. Fig. 2 is a back exterior elevation of the same, and Fig. I; is a transverse vertical section.

a is the outer annular chamber supported upon thebase I) and into whichthe ieated water from the motor is forced tlu'ough'the Specification of Letters Patent.

pipe 0 by the usuatIeiitculnnng pump not shown in the drawings.

d is the discharge radiator and from whic the cooled water is returned to the motor for fresh use constant circulation being thereby easily maintained.

In the present form of my invention I preferably make the outer annular chamber a of considerably smaller ca acity than here tofor'e' and internally anc concentrically thereof I arrange a secondary cooling chamber e held in position in any-convenient way. In the drawings the chamber e is shown as nearly surrounding the air propelling fan f or somewhat in the form of a saddle connec tion between it and the outer chamber a being effected by means of short pi es 9, g, g, g, the former g, g, being .ititte at the upper side as inlet pipes from the chamber ipe or outlet froin aand the latter 9', g, bein disposed at the with the base 6. a

It will be readily understood thatithe *chamber 2 may be made completely annular and provided with apertures or openings therethrough for the passage of theair from the fanf instead of in the form shown.

his the end plate for the front of the radiator which is made in the form of a hollow cover or. sup lemcntal chamber furnished with a central aperture 2' for the admission of cool air-to the central part of the fan j, j are short pipes connecting the cover It uith the annular chamber 'u and the base 6 respectively. In order that the proper connection and disconnection of the cover thereto may be easily ell'eeted I provide the pipes j, j nith flanges k, k arranged. to be secured to the cover it by means of screws, short cross over connections l, l being pro vided for the passage of the nater to and from both sides of said flanges as will be clearly understood on reference to Figs. l and 3 of the accompanying drau ings.

m is the end plate or cover for the back of the radiator which is made in the form of a hollow supplemental chamber as described tin reference to the front end cover /1.

n is an annular chamber formed on or fixed to the back of the radiator and connecting with the chamber a through a passage a (Figs. 1 and 23), with the base I) by means of a passage I), and wit ht hecnd plate or cover an through passages In, m, m we, (Figs. 2 and 3).

' o, o, are short pipes or air ducts through and not likely to get out of order.

the annular chamber n communicating with the space between the chambers (1 and e. These air ducts I prefer to make somewhat conical or tapered as shown.

p, pare bearings fixed t0 the end plates 71 and "m for the spindle g of the fan f.

r is an outlet connecting the lower part of the annular chamber a with the outer air a for the purpose of allowing dirt or other material drawn into the radiator immediately to fall out again without any possibility of damaging the fan.

s is a 'cap provided with holes for the escape of any steam that should accumulate in the radiator and t is an overflow pipe.

In use, the fan f is set in revolution by means of a belt passing over the pulley 11 (Fig. 3) and heated water from the engine being forced into the radiator, through the pipe 0 becomes thoroughly cooled during its circulation through the various chambers and passages before it reaches the return piped 'due to the absorption of the heath the constant flow of cool air through the device, and cool air being drawn in and driven round the space intervening between the annular chambers (1. and c and out I through the short pipes or airducts o, 0, on i to the motor and other parts to be cooled thereby greatly assisting in keeping down the temperature of the parts liable to overheating.

In practice I have found that by making the short pipes or air-ducts o. o, tapered or somewhatconical, as described, the objectionable noise consequent upon the air being forced therethrough is eniirelv obviated.

By my improvements the water is cooled in a thormighly simple and ell'ectivc manner, greater. economy in space is insured, while toe provision ol a removable part to the radiator gives free access for purposes of lubrication and cleaning, better results are attainable than hitherto possible and the entire apparatus is cheap to manufacture The details of construction may be varied more or less to meet different comlitions without departing from the nature of my invention.

WVhat I claim as my invention, and desire to secure by Letters Patent, is l 1. ln radiators or coolers for motor road l vehicles having an air-propelling l'an dis-, posed within an annular chamber, the coml binatii'm of a secondary cooling chamberl arranged concentric with the annular chaml l I l l l l l bcr surrounding said l'an, supplemental cooling spaces provided at the front and back of the radiator, inler-comnuuiicating pi es or connections between said annular chamber and the secondary and supplenrcutal cooling spaces; and a series of short pipes or ducts leading from the space between the two annular chambers through one of the supplemental cooling spuccsdiy which the air is directed about the porls to be cooled,substantially as described shown.

2. in radiators'or coolers for motor road vehicles of the kind hereinbelore rclcrred to, the combination of an outer annular chamher, a secondary cooling chamber urmnged within and concentric with the same. an air propelling lan surrounded by said annular chamber and provided with an opening or aperture for the air to'bc circulated bclwcen its exterior and the interior of saidnnnular chamber, and inlet and discharge pipes for the circulation of water lherelhrough, sub-- stantiallv as described and shown.
