PEA-TEE ATTACHMENT FOB- AUTOMOBILES.

' Application filed February 1, 1927. Serial No. 135,146.

' This invention relates to improvements in heater attachments for automobiles, applicable to that class of heaters wherein air surrounding the engine exhaust manifold 6 and heated thereby isconveyed by aduct through the dash of the automobile body into the seating compartment. The ob'ect of the improvement is to afford means 0 diverting the heated air in one direction or another in a l the compartment; distributing the heated air in said compartment more or less uniformly; or shutting off entirely the supply.

of heated air from entering said compart- -m'ent.,-

In the usual practice the heated air enters the seating compartment directly from a duct that extends through the dash, which duct is controlled by a damper, and the heated air, when admitted to the compartment is confined more or less about the point of entrance which is generally located at one side of the dash. Thus, an excess of warmth is provided for one of the occupants, while another occupant seated along side of the former occupant is supplied with but little,

if any warmth at all. The present invention contem lates supplying warmth for either one or 0th of the occupants in the seating compartment as may be desired.

These objects are accomplished by the construction illustrated in the accompanying drawings, in which Fig. 1 is a horizontal section of a construction embodying the invention' Fig. 2 is an elevation projected from Fig.

1, a ortion being broken away; and

Fig. 3 is an end view of the device posi tioned on the dash of an automobile, the dash' bein shown in section, there being included in t e view a fragment of a duct through which heated air is conducted to the appliance. a

' The invention comprises anQelongate-d case 1, one end 2 thereof being entirely open, an

an outlet opening 3 being made in the bottom of the case near the end thereof opposite the open end 2. A sleeve 4 projects from the back .5, of the case and has communication through the back with the interior of the case. A vertical partition 6 is disposed in the case in. line with the center of the sleeve which divides the case into two compartments 7 and 8 respectively.

A longitudinally mova 1e damper 9, having an opening 10 therein is disposed within the-case 1 and is held fiat against the back 5 thereof by means of guides 11, there being a pro ecting lip 12 at one end of the opening 10 t at has contact with the partition 6 when the damper is moved outwardly and thereby limits outward movement of the damper.

The back 5 of the case has made therein an indentation 13, and the dam r 9 has made therein a series of alined in entations 14, which the indentation 13 in the back selectively rojects accordingly as the damper is ad ustabIy positioned, whereby the damper is retained in its various positions of adjustment. In utilizing the invention the case is secured by any suitable means in position against the inner face of the dash 15 with the sleeve 4 protrudin through the dash and extending into the uct 16 so as tohave communication therewith. The duct 16 may be of any suitable form such as is ordinarily employed for conve ing air heated by radiation from the mani old of the automobile engine, to the seating com artment. First, when the damper 9 is move to its innermost osition, as shown in Figs. 1 and 2, the adacent end of the sleeve 4 is closed thereby and entrance of heated air from the duct into the case is thereby revented; second, when the damper is move outwardly to that position where the opening 10 of the damper reaches the partition 6, heated air passes from the duct into the com artment 7 from whence it passes through t 0 outlet 3 into the seating com artment; third, when the damper is move outwardly to a fart-her extent, so that its opening 10 is alined with the sleeve, heated air passes from the duct into both compartments 7 and 8 from whence it passes through the outlet 3 and the open end 2 of the case; and fourth, when the damper isrmoved to its outermost position, the li or d stbp 12 bears against the partition 6, an the entrance of air from the duct into the com partment 7 p is shut ofi by the damper which closes the corresponding portion of the sleeve, while air is admitted through the opening 10 in the damper into the compartment 8 and is directed through the open end 2 of the case into the seating compartment.

By this arrangement heated air may be supplied to different points or locations-in the seating compartment simultaneously or selectively, or, the supply. of heated air may be shut ofl entirely, by manipulating the damper.

By positioning the case to one side of the dash, preferably back of the exhaust manifold, in front of one of the seats in the seating compartment, heated air is-sup lied from the compartment 7 to-the feet the occupant of the seat, the air being directed downwardl throu h the outlet opening 3 while I heate air is i-rected laterally from e case through its open end'toward the feet of the occupant of the adjoining seat. By adjusting the damper accordingly,- the occupants of both seats may be supplied with more or less heated air as they may individually require for their comfort. 7

at we claim is v l. A heating appliance for an automobile having a; hotair supply duct, a case osi'- admit air from, saiddnct selectively-intoithecom artments of said case, or, into both actments, and. a.sliding dper hav-- Am as the damper is positioned said incense damper being also operable to shut communication between the duct and case'entirelyx I 2. In combination with an automobile having a hot air supply duct, a double compartment case having a separate outlet for each compartment; a connection with said duct having communication with said compartments; and a damper controlling com- ,munication' between the duct and said 60m partments whereby air from said duct is solectively admitted to said compartments or to both of said compartments, or, the air isshut ofi entirely from said compartments accordingly as said damper is adjustably po- I sitioned.

3. In combination with an automobile having a hot air supply duct, a case located within the seating compartment of the automobile and having communication with said duct, said case having two separate outlets; a damper controlling communication.

between said duct and case; and a partition within sa d case whereby air from said ductis discharged from said case into the seating compartment selectively through said outlets, or through both of said outlets accordingly as said damper is positioned. v
