Application and December so, 1020. Serial no. 434,107.
To all whom it may concern:
Be it known that I, WATSON B. STOCKMAN, a citizen of the United States, residin at Chester, in the county-of Delaware and of Pennsylvania, have invented certain new and useful Improvements in Diluting De- .vioes for Internal-Combustion Engines, of
which-the followin is a specification.
This invention refines to an improved fuel mixture diluting device for motor vehicle engines and has as one of its principal objects to provide a device whereby heated air may be introduced into the fuel mixture of an engine for aiding the vaporization of the mixture.
The invention has as a further object to provide a device wherein, if desired, cold air may be introduced into the fuel mixture for cooling the engine cylinders.
A still further. object of the invention is to provide a device which may be controlled from the instrument board of the vehicle.
The invention has as a further object to provide a device employing a distributor which may be interposed between the engine intake manifold and the carburetor for introducing air into the manifold.
And the invention has as a still further object to provide a device which may be readily installed'and which may be employed in connection with substantially any conventional design of internal combustion engine.
Other and incidental objects will appear hereinafter.

Fdr'convenience, I have, 1n the drawings, shown my improved device in connection with a motor vehicle en he 10 of conyentional desi The inta e manifold of the engine is indicated carburetor is indicated at 12. A1513 is shown the exhaust manifold of the engine. carrying the invention into effect, I employ a hollow concavo convex heater 14. This heater may be formed of suitable sheet metal and is curved to fit over the exhaust manifold 13 resting thereon. Secured to said heater is a bracket 15, the inner end portion of which projects over the engine head and engaged through said bracket is one of the bolts securing the head. Thus,
.securely held in osition.
Extending from the heater is a'discharge pipe 16 provided, as particularl shown in igure, 6, with a collar 17 whi e adjacent said collar the ipe is formed with an opening 18. Slidab 6 upon the pi )e to normally abut the co'llar overlying said opening, is a sleeve valvel19. The purpose of this structure will later appear.
lonnectcd to the pipe 16 at its outer end is the control valve employed. As best shown in Figures 3 and 4 of the drawings,
at 11 while the engine this-valve includes a. cylindrical casing 20 closed at one end and threaded upon the op posit/e end of the casing is a cap 21. Depending from the casin is a nipple 22 havmg a passage 23 therehrough w ile at its upper side, at a point opposite sai passage with a coldair inlet opening 24. reely slidable within the cans ing is a tubular valve 25 open at its ends and connected with said valve is a stem'26. which, as shown in detail in Figure 5, is formed with flat sides to coact with the cap 2i of the valve casing for holding the valve against rotation. The stem is connected with the valve by a transverse pin 27 extending through the inner end port-ion ofsaid stem and bearing between said pin and the cap 21 is a spring 28 surrounding the stem and normally holding the valve closed. Formed in the valve at..its upper and lower 'sides are openings 29 adapted to coincidistributer employedr and journaled between said lugs 15 a pull and 31 respectively. The opening 30 is ada ted to register with the inlet passage of tile casing leading fromthepipe 16 while the openin 31 is adapted to coincidently register wit the outlet passage 23. Threaded u on the outer end of the valve stem 26 is a sad 34 u on which is pivoted a ring 35 and swivels upon said rin ;is an eye 36 to which is connected one on of a control wire or cord 37. Mounted upon the instrument board of the vehicle or at any approved point, is the control member employed. As shown in detail in Figure 9, this member comprisesa split tubular body 35 which is preferably formed of suitable resilient sheet metal and at the ends of the body are ears 39 through which may be enaged suitable fastening devices vfor securmg the member in position. At one end of the body is a pair of upstanding lugs 40 3 41 over which the cord 37 is trained. Freely movable within the body is a tubular slide 42 to which the cord is'connected and projecting from said slide freely through the slot at the forward side of the body, is a handle 43. Formed in the body atthe lower side of the slot therein are s aced notches 44 and 45 respectively. As wil be perceived, the head 34 may be adjusted upon the valve stem 26 for varying theefi'ective length of the cord. I 1 a Connected to the nipple 22 of the valve casing. is a cut-off valve 32 of a proved design and extending from said va ve is a dpi 33 to the lower end of.whichis -attache t e As best shown in Figures 7 and 8, this distributor comprises a relatively thin body 46 which is provided with flat sides and is she ed to fit between the confronting flanges o the intake manifold l1 and carburetor 12,. openings 47 being provided in the body for receiving bolts or other fasteni devices connecting the carbureter with t e manifold so that said bolts will also serve to hold the distributor in position. The body is formed with a central opening therethrou h disposed to reg- 'ister with the passages o the carburetor and manifold and surroundin said opening is an annular distributing c amber .48 closed by a distributing ring 49 snugly but removably fitting in said opening. Through the ring is formed an annular series of discharge openin s 50 and overlying the ring at op osite en s thereof are mixing screens 51 suitably secured to the end edges of the ring. At one end the body 46 is formed with an upstanding nipple 52 threaded upon the lower end of the pipe 33 and leading from said nipple to the chamber 48 are diverging passages 53.
As will now be spr ng 28 readily understood, the of the control valve will normally hold said valve closed to cut oil communica- 147cm v tion between the heater 14 and the distributor, the slide 42 of the control member being in the sition shown in Fi re 9. By mov-i ing this slide toward the aft and rotating the slide to,engage the handle 43 thereof in the notch 44, the valve 25 may be shifted to a position having the opening 30 therein registering with the inlet passage of the casing and the opening 31 registering with the outlet passage 23.. Engine suction in the manifold 11 will then serve to draw hot air from the heater into and through the distributor to be discharged into the manifold. The heated air drawn into the distributor will, of course, fill the chamber 48 whence the heated air will flow in jets through the series of openings 50 into the transverse passage of the distributor between the screens 51. The fuel mixture flowing from the carbureter, upon passing through the first of these screens will be when up thereby and in this state will be pierced by the jets of heated air flowing from the openings 50. The jets of heated air will thus tend to supply the mixture with heat, so'that the mixture will be effectually vaporized and the temperature thereof appreciably raised. Upon passing through the other of the screens into the intake manifold, the mixture will then be further broken up and its par ticles commingled so that a homogenous fuel supply will be delivered to the engine cylin- 'ders. By moving the slide 42 of t e control member still further to the left and engaging the handle 43 thereof in the notch 45, the valve 25 will then be moved to the position shown in Figure 4 havingl the openings 29 therein registering with vt e opening 24 of the valve casin and with the outlet passage 23 respective The engine suction in the maifold will t en serve to draw in cold air through the valve and through the distributor' into themanifold. The valve 32 is provided so that should the control valve become disabled. communication between the valve and distributor may be out ofi.
Attention is now again directed toFigure 6. As will be perceived in view of the precoding, the valve 19 provides means whereby heated air drawn from the heater 14 may be diluted with cold air. This may be accomplished simply by shifting the valve along the pipe 16 to uncover the openin 18. Further, in cold weather, a suitab e priming fluid may be introduced into the pipe through said opening to be thence drawn into the intake manifold of the engine. he purpose of the opening 18 and valve 19 therefore becomes ap arent. 7
Having thus descri ed the invention, what is claimed as new is: I
l. A device of the character described including a'heater, a distributor, a pipe connecting the heater with the distributer, a valve casing inter i'osed in said pipe and provided with an atmospheric air ort and passages for said pipe, and a tubu ar valve slidable in said casing and provided with corresponding ports and passages for controlling communication with the distributer from the atmospheric air and the heater re-- spectively, and a control member slidable for shifting the'valve and adapted to be locked for sustaining the valve in either of said controlling positions selectively.
