Sept. 23, 1930. H. w. TURNER HEATER Filed Jan. 31, 1930 INVENTOR ATTQFINEY` Patented Sept. 23, 1930 UNITED STATES PATENT OFFICE HORACE W. TURNER, orrnoinvrx, `NEW `YORK HEATER Application. led january 31, 1930. Serial No. 424,841.

f where it maybe suitably tempered by heat derived fromv the exhaust of the engine. A further obJect is to provide' such a hollow heating member having open ends and a normally open bottom, which faces the exhaust manifold, .and facilitates the free upward radiation of the heat, which is absorbed by the continuous stream of .fresh air supplied by the fan, theinterio'rofsaid body being fitted with a staggered arrangement of baffles, 3 which compel the air streamto How in a course that undulates vertically throughout the length of the body, the arrangement of the lbales being such that the air is deflected toward the manifold and re-heated at regu larly recurring intervals during itspa'ssage through said body. A further object is to provide simple means for'clamping the heater body to the exhaust manifold. v And a further object is to provide novel metallic pack- 39 ingmeans for sealing the joint between the bottom of the heater and the top surface of the exhaust manifold, to prevent'leakage or deterioration of the heated air.

I attain these objects by the means set forth inthe detailed description whichfollows, and as illust-rated by the accompanying drawing, 1n whichl Figure l is a. broken side elevation of an Aair-cooled internal combustion engine, showing my heater imposed upon `the exhaust manifold. Fig. 2 is an enlarged top plan View of the heater. Fig. 3 is a verticallongitudinal section, taken on line 3-3 of Fig. 2, showing the orderly arrangement ofthe baiflesthat effect the serpentine flow of the heated air.

Fig. 4 is an enlarged vertical cross-section,

taken on line 4-4 of Fig. 1.1 And Fig. 5 is an enlarged vertical cross-section, taken on line 5 5 of Fig. 2.

In the drawing, 2 represents conventionally an air-cooled type of internal combustion vengine for automobile and airplane service. 3 represents the exhaust manifold, which is `common to theseveral cylinders 2'; And 4'` represents the usual fan by which the cooling blasts are generated, the fan being enclosed by a casing 4.V

My automobile `heater comprises anelon gated hollow cast or sheet metal body 5 of any suitable length and cross-sectional shape and area having reduced open endportions 5-5a, to Awhich flexible orother receiving and discharging tubes, as 6-6",inay,be applied, as'shown in'Figs. l and 2.` In practice,

:the body 5 is`preferably"mounted upon fthe top surface of the manifold -3 to which it may be readily and quickly secured by means of a number of stirrup-like clamps 7, the arm 7 of which may pass through lateral perforated lugs as 51. The freeends of said arms are preferably threaded to receive nuts?a between which and the top surface of the lugs are preferably interposed relatively stiff compression springs 7b,to providea certain amount of cushioning to aid in adjusting and conforming the heater body to the "manifold, as well as to regulatethe` pressure uponfav packing that intervenes the body 'and the manifold. The intake vtube 6 taps theV fan casing 4 and diverts a portion of the cooling fluid to the heater 5, and the discharge tube 6 may conduct the hot air to different parts of 4the tonneau (not shown) of the vehicle. The

bottom of the heater body is normally open and is preferably formed with ya continuous marginal groove 5C, which faces the manifold and in which is disposed a tubular packing 8, preferably consisting of copper, 01' annealed brass of suitablel gage, which may be pan. tially collapsed by pressure exerted by the springs 7]? by the tightening of the nuts 7a, as may be understood by comparing Figs. 4 and 5. In this way, the packing 8 may be made to conform to any unevenness of the surface` of the manifold and effect anair-tight lioint.

vAccording to `the present showing, the body 5 of the heater. is substantially square in crosssection, 'and its interior vis fitted with two series of obliquely disposedbathea 9 and 9. The baflles `9 are Vpreferably secured to the top wall of the body 5 by rivets 9a.A The baffles 9 rise from the bottom plane of, and may be cast with the body, or they may be detachably secured by any of the well-known means. The alternate arrangement of the baffle-s effect vertical undulations of the stream of air, as may be understood from thetortuous course of the arrows in 3. By this peculiar arrangement of the baffles, the air stream approaches and recedes from the highly heated top surface vof the manifold ,at regularly recurring intervals throughout the length of the heater body, which tends to progressively increase the temperature by intermittently re-lieating the air while the latter pursues its serpentine course. By this means, the hivhest possible degree of heat Veduced by radiation from the top or hottest portionhof the manifold may be generated in the body of the heater and distributed by the conductor 9'; o

i Having thus described my invention, what I claim, is-

1. In an air-cooled typeof internal combustion engine having an exhaust manifold and an encased fan, a heater comprising an oblong hollow body having open ends, Vone end communicating with the fan chamber, the side of said lbody that faces the manifold being open,

- and ,said body being provided'interiorly with oblique baffles arranged to Adirect the stream of-.air received from said chamber 1n an ung dulating course that effects' Vthe re-heating and progressive raising of the temperatureof the air, means to clamp the heater Abody to the manifold, and acontinuous tubular packing interposed between the open side of the heater and t-he adjacent surface of the manifold.

2. A heater for automobiles and the like, comprising an elongated hollow body open at its ends adapted to be mounted upon the exhaust manifold of an internal combustion engine and being provided with means vto receive air from thev fan-casing of the engine cooling system, said body having a normally open bottom that-faces the manifold, and a staggered arrangement of baiilesthat cause the stream of air to undulate and approach the radiating surface of the manifold at regularly recurring intervals to progressively in crease the temperature of the air as it pursues its course through the body, means acting under compression to resiliently clamp the heater body to the manifold, and afpaclring adapted to collapse under said compression to seal the oint-between the heater and manifold.

3, In an air-cooled type of internal combustion engine having an exhaust manifold and afan, a heater comprising an oblong hollow body having open ends, one adapted to communicate with said fan, and having an open bottomfto admit the heat radiated by the f manifold, said body being'provided interiorly with two series of staggered oblique baies adapted to direct the stream of air received from the fan in a course that undulates vertically in a plane that substantially parallels the abutting face of the manifold, whereby to intermittently increase the temperature of the air as it Hows through said body, means to clamp the heater body to the manifold, and a continuous collapsiblepacking interposed between the bottom edges of the heater body and the adjacent surface of the manifold.

4. A hot air generator for heating automobiles and the like, comprising an elongated hollow body open at its ends and adapted to be mounted upon the exhaust manifold of an air-cooled 'internal combustion engine and to communicate with and receive air from the fan chamber of the en gine cooling system, said body having an open bottom that faces the manifold and being fitted interiorly with staggered bales arranged in opposing series, that cause the stream of air to flow in a serpentine course that substantially parallels the top of the manifold, one series of baffles adapted to deflect the stream of air towards the manifold at regular intervals throughout the length of the body to cause the temperature of the air `to increase progressively, avseries of stirrups to clamp the body to the manifold,

said stirrups engaged with the'bottom of, and
