,5 operation of the engine of which it is a part of may be mounted without difficulty upon a carburetor of an engine.
Another object of the invention is to supply warm air to the carburetor to better pick up and gasify the fuel with which it comes in contact.
With these and other objects in view, the in- J vention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.
In the accompanying drawing:
Fig. 1 is an elevation of a portion of an engine illustrating the carburetor with my device positioned on the far side thereof;
Fig. 2 is an elevation showing the carburetor and my device attached thereto, looking at right angles to the position of Figure 1;
Fig. 3 is an elevation of my attachment compartment alone;
Fig. 4 is a sectional view substantially on line 44 of Figure 3 Fig. 5 is a perspective view of the shield.
With reference to the drawing, I0 designates a portion of an engine block having an intake manifold l and an exhaust manifold |2. A block or suitable elevating support 3 forms a mounting for the carburetor designated M which is secured thereto by means of cap screws l5 extending through the base portion I 6 thereof. A fuel control lever I! is pivoted at l8 and operated by the rod l9 from some suitable point of actuation to control the amount of fuel supplied to the engine. The air intake for the carburetor consists of an opening, designated and is surrounded bya tubular boss or nozzle 2|.
In order to control the supply of air to this intake nozzle or opening 2!], I have provided an attachment in the form of a closed compartment, designated generally 22 which consists of a generally rectangular box having opposite side walls 23, 24, edge walls 25, 25, top wall 21 and a bottom wall 28. A conduit or tube 29 extends from the walls 23 at a point adjacent its upper end and fits about the boss 2| while packing 30 provides an air tight connection thereto.
The opposite wall 24 of this compartment is provided with an opening 3| having a boss 32 extending therefrom with a longitudinal bore 33 and a valve seat 34. A lateral opening 35 communicates with the bore adjacent the valve seat while the flow through the opening 3| is controlled by means of a threaded member 36 having a head 37 and a conical valve 38 for engaging the J valve seat 34. I term this opening the primary opening because of the more or less permanent adjustment given to the member 36 to provide a constant entrance of the air to the opening 3| for the admission of air into the compartment.
At a lower location in the wall 24, I provide a secondary opening it) at one side of the center and a closure door or cover 4| of a size considerably larger than the opening and which is hinged to the wall 2 1 on. a pintle pin 42 and provided with a spring 43 to swing this door 4| to close the opening while an arm 44 is connected to-this cover or door M to move the same a certain amount away from the opening to control the admission of air to the compartment.
The arm 44 extends to a point beyond the side wall 26 and is there provided with an enlargement 45 having an opening 46 therein and a set screw 41 for securing a rod 48 in the opening in difierent adjusted positions. The arm 44 moves this flapper or door 4| varying amounts away from the opening to permit more or less air to enter the compartment and shield any forceful admission of air flowing at substantially right angles to the wall 24. The rod 48 extends to and connects with the offset end 49 of the rod I9 by means of an L-shaped portion 5| extending through an opening in the olfset 49. A helical spring 50 holds this portion 5| in position. By this arrangement upon movement of the rod |9 and the lever H, the rod 48 moves the cover 4| to and from open or closed position, as shown in Fig. 2, the arrangement being such that when the amount of fuel supplied is increased, a greater opening into the compartment will be provided.
I conduct the Warm air from about the engine into the openings in the compartment and to assist collecting and directing the warm air, I have provided a shield as at which is of a shape best shown in Figure 5. t has an opening 56 for the entrance of air to its upper end for supplying the primary opening 3|, whereas the air also enters the bottom at 51 to be conducted to the opening 4|) which is variably controlled.
A shield 58 extends to a point considerably below the compartment to assist in the conduct of air from about the engine into the shielded space 59 mentioned and which may be adjusted by means of a slot 60 in the shield and a binding screw and nut 6| and 62 to vary the size of the opening 56. This shield 55 which covers the openings and serves to conduct the heated air thereinto also serves by itself becoming heated to Warm the air which will'enter the compartment and also serves to provide a disturbed supply of air to the openings shielded, especially protecting them from a direct force which may be imparted to the air by means of a fan which forces the air backwards over the engine when the same is used in an automobile having a forward radiator.
By this attachment, I have found by tests which I have made that I can effect a saving of from 20 to 25% in the consumption of gasoline on a Chevrolet automobile.
The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of restorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
I claim:
1. In combination with an engine having an intake manifold, a carburetor connected thereto and having an air intake opening and a throttle control, a compartment communicating with said opening and through which all air received in said opening must pass, said compartment having a primary opening for the entrance of cold air in a fixed amount, a secondary opening, means for conducting air over the warmed parts to said secondary opening, and means operable from the throttle control for variably controlling the sec ondary opening to open the same as the throttle control is advanced.
2. In combination with an engine having an intake manifold, a carburetor connected thereto and having an air intake opening and a fuel supply valve, a compartment communicating with said opening and through which wall air received in said opening must pass, said compartment having a primary opening for the entrance of cold air in a fixed amount, a secondary opening, means for conducting air over the warmed parts to said ly adjusting the size of the passage through said primary opening, a secondary opening, means for conducting air over the warmed parts to said secondary opening, a cover for said secondary opening, and means for hingedly mounting said cover to cover or move from covering position over said opening in varying amounts in response to the throttle control.
4. In combination with an engine having an intake manifold and an exhaust manifold, a carburetor connected thereto and having an air intake opening, a compartment communicating with said opening and through which all air received in said opening must pass, said compartment having a primary opening for the entrance of air in a fixed amount, a secondary opening, means for variably controlling the secondary opening, and a shield adjacent the variable opening for directing the air currents with reference thereto. 7
5. In combination with an engine having an intake manifold and an exhaust manifold, a carburetor connected thereto and having an air intake opening, a compartment communicating with said opening and through which all air received in said opening must pass, said compartment having a primary opening for the entrance of air in a fixed amount,.a secondary opening,
means for variably controlling the secondary opening, and a shield over said openings for directing warm air about the engine into said openings.
