This invention relates to heaters for motor.

propelled vehicles and has for its objects the provision of a simple and convenient fitting for enabling the control of'the heater from any convenient art of the vehicle the rovision of a contro -fittin which sha interchangeably usable wit all {types of cars regardless of the relative positionof the valve and fitting;

maximum amount of force to be applied to the valve when the same is at or near. its closed position, or closing it against the carbon deposits usually encountered. in connection with such installations; while furtheriobjects and advantages of the parent as the description proceeds.

. In the drawings accompanying and forming a part of-the present application wherein I have illustrated one embodiment of said invention, Fig. 1 illustrates a part of an automobile .havin a heater attached to the exhaust" giantrovided with my improved" valve contro Fig. 2 is an enlar ed elevation partly in section of said va vs control; and Fig. 3 is a view taken at right angles to Fig. 2.

Describing the parts by reference characters, 1 represe nts the floor of an automobile,

2 the exhaust pipe, 3 a heater, and 4 a flexible conduit leading to the heater, the latter bein attached to the exhaust pipe by means of t e valve-fitting 5 clamped to; one side therein a valve member 6 adapted to-deflect more or less of the exhaust gases into the beaten. In its (preferred form t e valve member 6 is carrie by a retatable spindle 7 provided with a lever 8 and a closing spring 9 to which is attached the operating rod 10.

The-op site. end of thisrod is connected to a suite le-fitting secured at such place in the floor of the car as may necessitatediy e.

for the purpose of opening' invention will become ap-- sire of the owner, In its preferred construction thisdevice comprises an apertu red floor flange 12 having spaced side walls 13 and end-walls 14 surrounding the aperture, the bottom of the flange being formed at one side of'the aperture with a bracket 16 to; which is pivoted the segmental plate 17 fornied with spaced, apertures 18. Articulated to this plate as by a pin entering one of its-apertures isan 6 upwardly projecting handle 20, which traverses the aperture and is; provided at its u per end witha cross-piece 21 adapted to e. engaged by the hand. One sideoi this han dle is formed with spaced notches 22 adapt- 'acent wall of the aper- The opposite side ofthe handle is provided with a projecting portion 24 and the casing. is provided with a suitable abutment such as the rivet 25 so located as to engage said pro jecting portion and force the topmost notch into engagement with the detent portion 23, thus limiting the downward movement of the handle; r Y

The end of the rod 10 is formed with a transverse pivot portion 30 adapted to be inserted in one of the holes 18 where it is suitably held as by a cotter pin 31. The angular extent of the sector eing preferably at least the same forms a sort of universal bell-crank lever enabling the operation of the valve by this handle in any relative position of the valve and sector likely to be found in an automobile. In the present embodiment I have shown this rod as engaged with the third aperture, thereby causing the same to swing a substantially equal angle to each side of the midpoint. The valve lever 8 is also secured to the rock shaft so as to provide the bestpossible linkage connection. This ordinarily requires that the rod be approximately per endicular to the lever when'the valve' is he f open; and the rod is connected to such a point on the segment late as to remain as nearly parallel to its mean portion as ossible through its entire range of travel. t is obvious that these angles will vary with differences in height between the exhaust pipe and floor and difierences in horizontal d1s-.= tance between the valve and control fitting. This improved fitting constitutes in efiect, a universal bell-crank lever use la in all no relations from directvertical alignment to a full horizontal throw he flange 12 is shown as a plied to the bottom of the ear-floor, the wal s 13-44; being received in a suitable hole 35, covered by a slotted plate 36 to which the flange is bolted. In the present embodiment I have shown a floor-type heater located in the rear compartment of the automobile, the control device being located-in the forward compartment just ahead of the heel board 32. e closing spring 9 is so related to the parts as to hold the notches 22 tightly engaged. In case the handle is released the sprin closes the "alve with a forcible snap, dislo ging any carbon that. may have accumulated, the cam projection 24 servin to throw the handle so as to engage the last notch at the instant the valve is closed. In this way the tension of the spring 9 is utilized to take up any lost motion in the connections and prevent rattling. To this end -it is desirab to employ a rod 10 of such len th as to-eifect this engagement of the note just prior to the contact of "the valve with its seat-or withany stop carried by the valve itself. It will be understoodhowever that I do not limit myself tothe employment of any particular type of heater or valve-orlocation of control device, or

. any other feature of design, construction or in my claims.

Having thus described my invention what I claim is:

1. A fitting for the purpose described, comprising a slotted plate adapted to be attached to a floor, a bracket'carried by one side of said plate alongside said slot and formed. at a point removed from the plate with an extension beyond one end of said arrangement except 'as specifically recited slot, a lever pivoted to said extension, an operating handle ivoted to said lever and projecting through said slot, and a hand grip carried by said handle. 2. A fitting for the purpose described, comprising an apertured plate adapt-ed to'be attached to a floor, and formed on one side with walls at opposite sides of the said aperture and upon the other side with a bracket along the side of such aperture, the

end of said bracket being extended to a parallel to the plane. of, said flange and havmg'near its margin a series of spacedapertures, an operating handle articulated to said plate and projecting through said flange aperture, one edge of said handle .being 7 notched for engagement with the wall of said aperture and theopposite edge having a pro ection, an abutment carried by said flange adapted to engage said projectionwhen .the uppermost notch comes opposite said wall, and a rigid rod having a transverse pivot-portion adapted to enter vand be secured in one of. the marginal apertures of said plate.

In testimony whereof, I hereunto aifix my signature.
