Fig.3.

The heater chosen for illustrative purposes in the accompanying drawing comprises a shell or body portion I 0 preferably cylindrical in shape 40 and formed of sheet metal. A plurality of apertures ll'arranged in any suitable manner such as a series of longitudinally extending slots. serve as passages through which air may flow in a manner to be hereinafter more specifically de-1 46 scribed. A rear cover plate I2 is adapted to be secured to the shell ill in any approved manner such as by soldering or spot welding an inwardly directed flange 13 within. the shell. A central portion H of the cover plate I2 is preferably 60 dished inwardly and terminates in a forwardly extending tubular portion IS. A plurality of apertures I are formed in the dished portion l4 of the cover plate l2. Holes l1 and I8 preferably diametrically spaced above and below the center 65 of the cover l2 are adapted to receive pipes 19 shell Ill.

.sure proper operations of the gears. element 42 is adapted to be secured to the lower 60 and 20 which are respectively inlet and exhaust pipes. Plugs serve as closures for the forward ends of pipes 19 and 20 respectively. A spacer element 22 connects the forward ends of the pipes l9 and 20 and serves to retain them in proper spaced relationship. The element 22 is secured to the plugs 2| and in any suitable manner such as by the use of turned ears 23, and it is preferably provided with ends or feet 24 adapted for anchorage to the shell I2 to retain the forward i0 portion of the shell perfectly rigid. The pipes I3 and 20 are provided with a series of spaced holes 25, and 26 respectively. These holes are preferably elliptical to receive thin walled tubes 21 which are similarly shaped. Fins 28 also formed ll of thin sheet metal strips are provided with oval openings 29 bordered along one side with ears 30 formed of the stock struck from the fin in making the openings 29. A plurality of tangs 3| are also struck from the fins these tangs serve as 20 spacer elements to retain the fins in proper spaced relationship on the several tubes 21. The ends of the tubes 21 are preferably soldered in the holes and 26- to form water tight joints.

An electric motor 32 is supported within the 25 The forwardly extending tubular portion l5 formed in the center of the rear cover I2 is adapted to receive the rear bearing housing of the motor. This housing may be anchored in the portion I5' in any suitable manner such as by the use of set screws (not shown). The forward motor bearing housing may be similarly received and retained in an opening 33 formed in the spacer element 22. In this simple and effective manner the motor is securely and rigidly mounted. An armature shaft 34 of the motor 32 is ,iournalled in a rear bearing 35 and a pair of spaced front bearings 36. A worm gear 31 is formed on the shaft 34 intermediate the bearings 35. A fan or propeller 38 is secured to the for 40 ward end of the armature shaft in any suitable manner so as to rotate therewith as a unit.

The front end of the motor housing is preferably formed in upper and lower parts 33 and 40 respectively. These parts serve to retain the front bearings 36 in proper alignment. A chamber 4| is formed by recesses in the parts 39 and 40.

This chamber serves to retain a lubricant to as- A tubular wall of a laterally extending portion 43 formed integral with the portion 40 of the motor housing. A shaft 44 passes through a longitudinal bore 45 in the element 42. A worm wheel 46 is keyed tothe upper extremity of the shaft 44 and 36 front cover 6|.

2 4 the same is in mesh with the worm gear 31. An

oflset portion 41 is formed adjacent the lower ex-.

tremity of the shaft 44. The extreme lower end 48 of the shaft 44 is journaled in the lower wall of a box-like enlargement 49 on the end of element 42.. The offset portion 41 forms a crank arm and is adapted to receive one end of v a connector link 50. The other end of the connector link 58 is pivotally mounted on an upstanding portion 5| of an arm 52 which is suitably secured to a central vane 53 which extends from top to bottom of the shell I8 and is journaled for oscillation in inwardly and rearwardly directed tangs 54. Two similarly mounted vanes 55 are spaced laterally on either side of the vane 53. These vanes 53 and 55 are preferably anchored .together so as to oscillate in unison. I have chosen to pass a bar 56 through aligned apertures 51 and provide vertically disposed elements 58 which pass through enlarged portions on the bar 56 and are suitably anchored to the vanes 53 and 55.

The-forward end portion of the shell I0 is provided with a plurality of spaced resilient fingers 60. These fingers serve to releasably retain a This cover comprises a ring element 62 the rear portion '63 of which overlies the .shell l0. A slightly depressed annular groove 64 cooperates with the fingers to retain the cover portion in position on the shell. A grill 65 preferably formed of a plurality of vertically and horizontallydisposed wire elements serves to provide a protective screen for the open front of the shell.

The entire heater element is mounted as a unit on a dash board 66 which is provided with a pair of spaced holes 61 and 68, a pair of pipes 69 and 10 respectively pass through these holes and are secured in position on the dash board by means of Jam nuts II, which are threaded on the pipes. A manually operable valve 12 serves as a connector element between the forward end of pipe 69 and the rearward end of pipe IS. A union [3 forms a similar connection between the forward end of pipe 10 and the rearward end of pipe 20. Fluid conducting conduits 14 and 15 which may be either rigid or flexible are respectively connected to'thev rearward ends of pipes 69 and 18 by means of unions 16 and 11. The forward ends of these conduits may be connected into the cooling system for the radiator or to'a jacketed portion of the exhaust manifold to form a com-. plete fluid circulating system through the pipes l9 and 20 and tubesZ'l.

A suitable manually controlled electric switch (not shown)v serves to control the operation of the electric motor and the valve 12 serves to control the flow of heating fluid through the pipes 20 heater.

and tubes. 21.'v The operation of the heater may be described briefly in the following manner. A handle I8 on-a-valve stem 19 of. the valve I2 may be turned to its open position to permit the flow of water from the cooling system through the It will be noted that the flow of water through the inlet pipe I! will divide itself and flow downwardly through the oppositely disposed oval tubes 21 and join together in the outlet pipe by said, motor for effecting movement of said flns requires the intimate contact of the air with the heated surfaces of the tubes and fins to thereby effect an extremely rapid and eflicient heat exchange whereby the temperature of the air is raised materially. After the air has been 5 drawn through the radiator of the heater it is dispelled through the grill 65. Rotation of the electric motor results in rotation of the worm gear 3'! which in turn eilects a relatively-slow rotation of the worm wheel 46. .The shaft 44 is 10 thereby rotated and the resulting action on the crank arm 41 effects the oscillation and reciprocation of the connector link 51']. The forward and rearward'movement of the connector link 50 eifects oscillation of the central vane 58. The 15 other vanes 55 are simultaneously oscillated through the reciprocating movement of the bar 56. The oscillating of these varies results in a new. and improved circulation of heated air throughout the interior of the vehicle.

The combination of elements, above described, cooperate to form a heating device containing not only numerous structural advantages, but functional advantages which are far in advance of present day methods. The oval formation of the The flow of air induced by the fan 38 draws cool air through the openings l6 in the dished portion l4 of the rear .cover plate I 2. This flow of air passes directly over the entire motor casing and results in maintaining the temperature of the motor within its range of eflicient operation. P While the invention has been describedfor use as a heater, it should be-understood that by cutting off the circulation of fluid through the radiator that thedevice will function equally well to effect a' circulation of air for the purpose of 45;

cooling the vehicle during the hot summer months.

While the invention has been described in considerable detail in the foregoing, specification it is understood that various changes maybe made in its embodiment ,without departing from or {10V sacrificing any of the advantages hereinafter v claimed. 1
