I F. WALTER AIR CHOKE FOR GAS MOTORS FiledrAugust 11,
Patented June 1, 1926.
UNITED STATES PATENT OFFICE.
AIR GI-IOKE FOR GAS MOTORS.
Application led August 11, 1924. Serial No. 731,479.
This invention is an air choke for gas motors, and consists of the novel features herein shown, described and claimed.
An object is to make an air choke which may be readily applied to gas motors already made and in use.
Other objects and advantages will appear from the drawing and specification.
The ligure is a fragmentary front elevation of an exhaust manifold, an intake manifold, a carburetor, an intake heater, and an air choke embodying the principles of the invention applied to the intake heater, parts being broken away and shown in section.
The details of construction and operation are as follows: The exhaust manifold 1, the intake manifold 2, the carburetor 3, and the intake air heater 4 are of the usual construction.
The intake air' heater 4 has an elbowshaped upper end 5 and the elbow is tapered, the large end 6 being wide open and con1 siderable larger than the small end 7. A tapered neck 8 connects the elbow 5 to an elbow 9, which is connected direct to the intake end 10 of the carb-uretor 3.
The air choke is cup-shaped and has a tapered circular wall 11 and a flat bottom plate 12 with a central opening 13. The
wall 11 is tapered from the top downwardly to fit the taper of the neck 8 so that the gas saver may be inserted through the large open end 6 and pass downwardly until it forms a tight lt in the neck 8. The open- 5 ing 13 is smallest at the top and flares outwardly. The Wall 11 serves simply to locate and support the plate 12 carrying the downwardly flaring opening 13. Any means for mounting the plate 12 in the line of draft through the air heater 4 and transversely of the line of draft` would serve the same purpose, the object being to produce a resistance to increase the vacuum or suction in the carburetor 3.y This makes it necessary to screw down the needle valve 14, thereby increasing the velocity of the flow of gasoline upwardly past the needle valve, and reducing the aggregate amount of: gasoline.
The result is a more perfect mixture forming the explosive gas and a great saving in gasoline.
Thus I have produced an air choke for gas motors comp-rising a plate having a central opening and a mounting for the plate adapted to be inserted into an air heater in front of a carburetor, and forming a resistance to the draft through the heater.
Various changes may be made without departing from the spirit of the invention m as claimed.
I claim An air choke for gas motors comprising a cup-shaped body having a circular tapered wall and a flat bottom plate with a central opening, the body being adapted for insertion through the open end oi'fan intake air heater to form a permanent resistance to the draft through the heater and the tapered wall of the body being adapted to engage the wall of the intake heater.
In testimony whereof I have signed my name to this specication.
FRED WALTER.
