Application filed December 12, 1917. Serial No. 206,8d2.
To aid rv/tom it may concern Be it known that 1, WILLIS M. SHAW, a citizen of the United States, and resident of Newton, in the county of Jasper and State of Iowa, have invented a certain new and useful Combination Manifold and Fuel Heater and Auxiliary Air Device, of which the following is a specification.
T he object of my invention is to provide a combination manifold and fuel heater and auxiliary air device of simple, durable and inexpensive construction.
More particularly it is my object to provide a device comprising a fitting adapted to be mounted on and to communicate with the manifold of an internal combustion engine and having a valve and a cup arranged to communicate with said valve, and located adjacent to and below part of the manifold, whereby the manifold may be heated by burning fuel in the cup.
With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:
Figure 1 shows a side elevation of an engine equipped with a device embodying my invention, and
Fig. 2 shows a horizontal, sectional view through a portion of the manifold, taken on the line 2-2 of Fig. 1, illustrating the attachment in plan view.
in the accompanying drawing, which illustrates a form of my invention, 1 have used the reference numeral 10 to indicate generally an engine of the internal combustion type, having an intake manifold 11. The engine is designed to be mounted on an automobile having the dash 12.
My improved combination manifold and fuel heater and auxiliary air device comprises a valve casing forming part of the fitting, having a cylindrical, tubular, externally screw-threaded extension 14 adapted to be screwed into a hole tapped in the wall of the lower portion of the intake manifold 11. On the opposite side of the extension 14: is another cylindrical, tubular. externally screw-threaded extension 15. The case 13 contains a valve having a stem 16.
in connection with the valve 1 provide a cup 17' having in its lower wall a hole through which the extension 15 is extended for permitting the lower interior of the cup to communicate with the valve.
Mounted on. the valve stem 16 is an arm 18. Pivotally mounted on the arm 18 be tween the ends thereof at 19, is a controlling rod 20 inclined. upwardly and rearwardly through the dash 12. At the lower end of the rod 20 is a flat strip 21, which is pivoted to the arm 18 at a point between its ends. On the end of the strip 21 farthest from the dash is a flange or lateral extension 22.
111 the practical use and operation of my improved device, the parts are installed on a manifold in the manner hereinbefore described, with the cup 17 standing below and near to that part of the manifold through which the fuel mixture enters the cylinders.
in the practical use of the device the rod 20 is pushed to its downward limit of movement, when the flange 22 will engage the projecting free end of the arm 18, thereby limiting the movement of the arm 18 and preventing its forward movement beyond the perpendicular. At this point in the movement of the arm 18, the valve is closed.
A small amount of fuel is put in the cup 17 and set on fire. The heat from the burn ing fuel will warm the intake manifold and particularly that portion immediately above the cup. The engine should be turned over a couple of times before the fuel is lighted in the cup 17. so as to draw a fuel mixture into the manifold.
After the fuel has burned for some time in the cup 17, the operator can crank the engine, and the heated fuel from the manifold will be drawn into the cylinders and can be readily fired therein. When desired the operator can pull the rod 20 rearwardly and upwardly, thereby swinging the arm 18 from its position hanging downwardly, to position substantially horizontal as shown in Fig. 1, when the flange 22 will engage the lower edge of the arm 18 for limiting the upward swinging movement of the arm 18 at a position where the valve is open. The valve will be open when the rod 20 is in its upper limit of movement. for admitting air to the intake manifold.
][t is obvious that my device may be used as a primer. lln this connection attention is called to the fact that when the cup 17 is only partly full of fuel, the fuel can be burned for a short time and before it is entirely burned out the flames will heat the upper edge of the cup and the heat will be conducted by the metal to the bottom of the cup 17 and to the fuel, sothat the fuel in the cup will be .warm. If desired the operator may manipulate the rod 20 for permitting some of the warmed fuel to pass into the intake manifold. The valve can then be closed, and a very rich fuel mixture can be drawn into the engine cylinders.
After the engine is running freely, it is often desirable to open the valve slightly for thinning the mixture and affording an auxiliary air supply. It will be seen that the device may be used in a variety of ways as a primer, fuel heater, manifold heater and auxiliary air supply device.
Some changes may be made in the construction and arrangement of the various parts/of my improved device without departing from the essential features and purposes of my invention, and it is my intention to cover by my claim any modified forms of structure or any use of mechanical equivalents which may be included within their scope.
I claim as my invention:
In a device of the class described, the combination of a frame member, with a valve casing having a valve therein, provided with a stem, said casing having cylindrical opposite tubular extensions, one of said extensions being adapted to connnunicate with a fuel passage of an engine, a cup mounted on and communicating with the other of said extensions, an arm on said stem, a rod pivoted to said arm and extended through a part of said frame, said rod being pivoted near one end to said arm at a point between the ends thereof, the last described end of said rod having a lateral extension, adapted to engage said arm in different positions of the longitudinal sliding movement of said rod, whereby the longitudinal. movement of the rod in both directions is limited.
