FREDERICK OLSON AND HENRY G. GOSSELIN, 0F BERLIN, NEW HAMPSHIRE. AUTOMATIC MIXTURE-REGULATOR FOR CARBURETERS. i
Specification of Letters Patent.
Patented Jan. 16, 191 7-.
Application filed April 6, 1916. Serial No. 89,328.
To all whom z'tmay concern Be it known that we, FREDERICK B. OLSON and HENRY G. GossnnrN, residing at Berlin, in the county of Coos and State of New Hampshire, have invented certain new and useful Improvements in Automatic Mixture- R-egulators for Carbureters, of which the following is a specification.
Our invention relates to certain new and useful improvements in devices for "automatically supplying auxiliary air to the gaseous mixture passing from a carbureter to the intake manifold of an internal combustion engine, and in its generic nature, the invention has for its object to provide a device as a new article of manufacture, of a simple and effective construction that can be easily attached to the carbureters at present 'in common use without the necessity of re constructing such carbureters.
In its more specific nature, the invention comprises an auxiliary air valve designed to admit air into the gaseous mixture at a place above the carbureter throttle valve, the admission of such air being controlled by the suction produced in the carburetor below the throttle valve, there being an air valve in the device controlled by the variation in pressure, due to the suction produced in the carbureter discharge passage below the throttle valve, as the throttle valve is open and the engine speeds up. I
The invention includes also those novel details of construction, combination and arrangement of parts, all of which will befirst described, then be specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a carbureter and a portion of the intake manifold illustrating the invention in use. Fig. 2 is a side elevation of the parts shown in Fig. 1. Fig. 3 is an enlarged vertical longitudinal section of the invention, theparts being shown in elevation. Fig. 4 is a plan view of the lower half section of the casing of the device constituting our invention.
In the drawing, in which like numerals and letters of reference indicate like parts in all of the figures, 1 represents the carbureter, which may be of the usual type, and 2 designates the intake manifold of the engine, the carbureter having the usual throttle valve 3.
Our invention, comprises a casing formed of an upper section 4 having a flange 5 that -1nto two parts is securedat 33 to the seat flange 6 of'the lower section 7 of the casing, the sections 4 and 7 inclosing a chamber which is divided by a flexible partition 24 that 1s clamped between the flanges 6 and 7. The casing section 7 is provided with air 1nlet openings 8 and a valved air passage 9 that leads into a chamber 12 which is in communlcation with a duct 13, whose nipple end 14 is designed to be tapped into the intake manifold 2 above the throttlevalve of the carbureter. The casing section 7 includes the extension 10 that is provided with the chamber 12 and duct 13, the extension 10 also having a valve opening 11 to admit air into the chamber 12 for passage into the chamber '13, whenthe valve 27, whlch controls the opening 11, is unseated.
The upper section 4 has an entrance duct 15 and a neck 16, the latter being tapped to receive a bushing 17 which is designed to engage a tension spring 25 hereinafter again referred to. The bushing 17 is bored at 18 to receive the valve stem 19, the stem 19 being threaded at 20 to receive the nuts 2122 and washers 23 by means of which the diaphragm 24 is secured to the stem 19. The stem 19 is seated in the duplex valve 26, the valve 26 having the valve heads 27, for the passage 11, and 28 for the passage 9 hereinbefore mentioned.
29 is a jam nut on the bushing 17 for securing it in the neck 16, and 30 is a nut head on the bushing, by means of which the bushing may be screwed in or out to vary the tension on the spring 25.
31 is a cap screw secured by a nut 32 in the bushing 17 to engage the valve stem 19 and limit its raising or inward movement, the screw 31 being adjustable so that the movement of the valve 26 may be .varied as conditions may make necessary.
34 is a nipple screwed into the duct 15 to which the pipe 36 is secured by the gland nut 35, the pipe 36 being also secured by a gland nut 37 to a nipple closure 38 that is tapped into the carbureter below the throt tle valve 3. In operation, when the engine is running idle, the suction above. the throttle valve is considerably greater than the suction below the throttle valve and hence the auxiliary air valve 26 will be kept in its closed or seated position. As the throttle valve 3 is open and the engine speeds up,
to counterbalance and later overbalance the suction at the discharge end of the duct 13 and consequently cause the formation of a,
engine without changing the established .carbureter adjustments and hence a saving in the. use of gasolene with consequent increased mileage per gallon is had.
Fromthe-for'egoing description taken in connection with the accompanying drawing, the complete construction, operation and 1 advantages of our Invention will be readily understood by those skilled in the art to 1 which the invention appertains.
.. :What we claim is:
' 1.-In combination with a carbureter having a throttle valve, of an auxiliary air admitting device connected to deliver air into the mixture after the same has been past the throttle valve, and means governed by thesuction below the throttle valve for controlling the action of the auxiliary air admitting device.
2. In combination with the carbureter having a mixture discharge duct governed by a throttle valve, an auxiliary air device comprising a casing having air induction ports and an air eduction port, the latter being connected to' deliver the air into the mixture abovethe throttle valve of the carbureter, said device including an air governing valve, and means connected with the carbureter discharge duct below the throttle valve for governing the action of such air valve.
3. In combination with the carbureter having a mixture discharge duct governed by a throttle valve, an auxiliary air device comprising a casing having air induction ports and an air eduction port, the latter being connected to deliver the air into the mixture above the throttle valve of the carbureter, said device including an air governing valve, a diaphragm to which said air valve is connected, said casing including a vacuum chamber at one side of the diaphragm, and a duct-connection between said chamber and the carbureter discharge duct below the throttle valve.
4. In combination with the carbureter having a mixture discharge duct governed by a throttle valve, an auxiliary air device comprising a casing having air induction ports and an air eduction port, the latter being connected to deliver the air into the mixture above the throttle valve of the carbureter, said device including an air governing valve, a diaphragm to which said air valve is connected, said casing including a vacuum chamber at one side of the diaphragm, a duct-connection between said chamber and the carbureter discharge duct below the throttle valve, and means for adjusting the effective action of said valve.
