10 Claims.

This invention relates to an improvement in heaters, and particularly to that type of apparatus designed for vehicular installation.

It is an object of the invention to provide a heater which is directional in its radiation, and which can be easily manipulated 'to change the path of travel of the radiated heat.

Another object is that of providing a heater in which the output, of radiated heat may be controlled in order to raise or lower the temperature of the surrounding air.

' A still further object is that of providing an apparatus of this character which is relatively rugged and simple in construction, and will op- 5 erate over long periods of time with freedom from mechanical difficulties.

With these and other objects in mind, reference is had to'the accompanying drawings, in which:- I

Fig. 1 is a front view of a heater embodying certain aspects of the invention;

Fig. 2 is a side elevation of said heater partially broken away along the lines 2-2 and in the direction of the arrows as indicated in Fig. 1;

Fig. 3 is a sectional plan view of the heater taken along the lines 3-3 and in the direction of the arrows as also indicated in Fig. 1; and

Fig. 4 shows a modified form of actuating member for the heat deflecting vanes.

In the several views, the heater shell or body cover is shown at l0 positioned over a conventional heater core and head assembly I I. Ornamental strips l2 are formed with rivet pins I3, which are passed through openings in the shell and thereafter flattened or headed as at M, thus holding the parts in position. Shell I0 is provided on its front face with bearing portions l5, in which shafts l6 are rotatably mounted. These shafts, in turn, have manipulating knobs H at the outer ends thereof, and pinion gears l8 mounted on their inner ends; these gears being held in position as, for example, by means of screws Hi. In this connection, it will be noted in Fig. 1 that the lower ends of the shafts I6 are preferably squared so that the gears l8 are positively engaged without any danger of slippage. Interposed between the adjacent faces of the knobs and the shell are gaskets or washers 20, which may be made of felt, leather, or other Y suitable material.

Adjacent the gears I8 and cooperating therewith is a ring gear 2| which is provided with a rearwardly extending flange portion 22. A ring shaped plate 23 is coupled to this flange by rivets 24 or equivalent fastening means, this 1935, Serial No. 36,06!

plate having an outwardly and rearwardly extending flange 25 which bears against the shell l0 adjacent the bearing members l5. Upon manipulation of either of the knobs l1 the ring gear and the attached plate are free to rotate, and the latter may be turned so as to assume any position that may be desired.

Carried by the plate are a series of heat deflecting vanes 26 which are shaped to conform to the circular opening of such plate. These vanes are each provided with handle portions 21' which may be formed integrallytherewith or secured thereto by means of rivets 28, as shown in Fig. 3. Each of the vanes may have one of its ends providing a pivot pin 29 which rotates within an opening 30 in the plate 23. At the opposite end of each vane a pivot pin 3| is 'slidably carried in bearing

portions

32 and 33 and is encircled by a coil spring 34 which, in cooperation with the bearing portion 32 and the shoulder forming a part of the pin, tends to force the latter into position in the opening 36 formed in'the plate 23. The rear end of the bearing pin is distorted as at 31 or otherwise secured to prevent an accidental displacement of the pin when the parts are disassembled.

In assembling the apparatus each of the deflecting vanes is mounted upon the plate by placing the bearing pin 31 thereof in the opening 36 and then moving the entire vane in the direction of the opening 36 so as to compress the spring 34 and move the bearing pin inwardly. The bearing pin 29 can thereupon be inserted in the opening 30 and the vane allowed to move in the direction of the opening 30 under the urging of the spring 34. In addition to providing a ready means of assembly, the spring provides a sufficient tension on each of the vanes so that they may be maintained in any desired position.

In operation, all or any of the deflecting vanes are-moved about their respective points of pivot to assume predetermined positions, as, for example, shown in Fig. 2. Thereafter, the manipulating knob or knobs are turned to rotate the 45 plate so that the air blown through the core by means of the fan will be deflected to either side of a plane intersecting the heater and any desired portion of the vehicle interior. To overcome any tendency towards looseness or rattling, the plate 23 may be provided, as shown in Fig. 2, with a suitable number of spaced sockets 38, each of which receive a coil spring 39 and a ball 40, The latter under pressure from the springs bear against the surface of the shell l0 and prefin ' 6 alternative form 10 tending flange 44 and vent rattling of the parts, although allowing the cover plate to rotate freely with respect to the frame.

Referring now to Fig. 4, there is shown an cover plate. In this case two friction disks ti are carried by the shaft or shafts 42 and which extend to either side of a friction ring 43. This ring is likewise provided with an inwardly exis secured to the plate E5 y rivets 46,]or' other suitable means. A coilspring #31 bears against the lower surface of the inner friction disk, thus clamping the friction ring under pressure between the two, friction disks. The spring is held in position by means of, for example, a screw48. In operation, the turning of the manipulating knob'49 effects a turning of the friction disks 48, which, in turn, carry with them the friction ring 43, resulting in a rotation of the plate. discussed modification, a washer 50 is placed between the knob and the ornamental strips.

It is apparent that while two manipulating knobs are disclosed in all forms of the apparatus, it will be understood that theshroud is coupled in any desired manner with the head and core assembly. The shell and parts hereto"- fore described are assembled, and thereafter they are telescoped over the core assembly and attachedin any desired manner thereto. It is also apparent that the same general results could be obtained by omitting one of the manipulating knobs and its dependent gear from the assembly. Thus, among others, the several objects of the invention, as specifically aforenoted, are

achieved. It will be understood that numerous heater.
