Abstract

Fuel flows from a pump to a chamber M through an adjustably spring-loaded ball valve B to provide a constant chamber fuel level. Valves 21 and 22 with V grooves are adjustable axially to control fuel flow to the carburettor induction passage. The valve 21 is adjustable by a ramp 42 on an angularly adjustable air throttle valve 4 with openings movable into alignment with openings in the induction passage wall. The valve 22 is adjustable by an eccentric Z which it abuts. <IMAGE>

Description

SPECIFICATION Improvements in carburetters for internal combustions engines This invention relates to a Floatless and Jetless Carburetter which cannot catvh fire, as in Float Carburettere which can flood, with loose petrol about especially if there happens to be a slight collision, then people get badly burnt, and apart from which, it is adjustable to combine the correct-proportion of air to fuel at all speeds which in every case produces decidely more power showing more miles per gallon and does away with polution, such a carburetter has never been in practical use on the market.I am modifying my Invention of 1 922 which was then gravity fed, but due to constant fires through the float carburetters the petrol tank which used to be right behind the engine, had to be moved to the back of the car and pumped through with a petrol pump on the engine to the carburetter, but my carburetter being gravity fed, after considerable testing with 10 Cars and lorries several for 3 Months periods and all wanted to purchase my patents which I would not sell I could not use my carburetter, I am now modifying it to suit the petrol pump on the car.

In order that my invention may be clearly understood I refere to one form of my carburetter in the accompanying drawings.

Figure 1 Is a view of the carburetter with the flanged body fitted to the base and the throttle in between with air ports at both ends, the angled platform with the racks and pinions for adjusting the gradiant and the connection of screwed spindle resting on the platform carrying the forked lever passing through the body.

Figure 2 Is a sectional view of the whole carburetter showing all the working parts so that they can be easily picked out with the reference letters or figures.

Fuel from the fuel pump enters the carburetter at A. made for a hose pipe through fuel flows but is restricted by a ball B. held tight on its seating by a long screw C. pressing against a spring E. in a short floating cup F.

until the screw C. is slackened permitting the pressure of the pump to move the ball of its seating, the fuel then passes along the channel and through the two openings marked L and into a large cavity M. within the base of the carburetter serving as a reservoir to serve both slow and fast running valve, the slow running valve marked N. the fast running valve marked 8. TWO hexagon screwed and recessed nuts 9A and 9B are fitted to the nose of the base, and petrol resisting plastic rings are fitted in the recesses and held tight by colars 20 and 14. and long springs 16.

and 1 7. fitter on valves N. and 8. the valves long rods on which VARIABLE LONG V.

GROOVES ARE CUT on each the grooves being variable in depth as well as in width, the variable V. grooves Passing through the plastic rings permit the necessary amount of fuel to pass as required for both of the valves.

The end of the slow running valve carries the spring the bottom of which rests on an EC CENTRIC Z. the eccentric made on a screwed rod fitted with packing gland and knurled turning knob 30 and 31 so that by turning the eccentric the variable V groove is varied for adjustment. The fast running valve although the same procedure is followed regarding the flow of fuel the operation is different, the spindle 34 screwed carrying the forked lever 36 and spring 37 and encased 38, the spring held down by nut 39 the forked lever 36 passing through the body, the fork with washer and nut on the screwed part of the fast running valve is adjusted to suit the required gradiant of platform 42 the adjustment of the gradiant is by the racks 45 and pinions 46.

The base is screwed to the body with flange for fitting to the engine, and the throttle telescopped on the body with the air ports 50 and 51 crossing those in the body, and fitted between the base and flanged part of the body, so that by revolving the throttle from zero opening to full bore, any variation of air can be obtained to suit from 10 HORSE POWER TO 100 HORSE POWER, and to obtain the correct proportions of air to fuel at all speeds.

To adjust the carburetter, the eccentric for the slow running, and an eccentric fitted at the back of the throttle is moved against a stop on the body, so by rotating the throttle the fuel and air when adjusted will show the correct proportions for combustion and slow running.

For faster running the gradient is raised according to the throttle opening which increases the fuel at the same time as you rotate the throttleaa after adjustment has been made.

1. Is a Floatless and Jetless Carburetter having a nozzle with a hole through which fuel passes from the fuel pump to the carburetter but is stopped by a ball on its seating held tight by a long screwed rod passing through a packing gland and spring held in a short floating cut, all lying in a channel, When the screw is slackened, the pressure of the pump forces the ball of its seating and permits the fuel to flow through two openings and into a large cavity or reservoir within the base to feed the slow and fast running valves.

Any back pressure reacts back on the spring and ball keeping the fuel at a constant level.

Another asset, to save the car from being stolen, is to turn the screw to close the flow, then no fuel can enter the carburetter, but to

Another asset, to save the car from being stolen, is to turn the screw to close the flow, then no fuel can enter the carburetter, but to start again turn the screw to slacken the spring.

2. Is a Floatless and Jetless Carburetter, as claimed in claim I. in which the nose of the base is fitted with two Hexagon screwed nuts recessed for petrol resisting plastic rings through which both slow and fast running valves with long variable V. grooves are cut and pass through the plastic rings and hexagn nut each to be varied seperately, the slow running raised or lowered by an eccentric made on a rod having a packing gland passing through the base and actuating the slow running valve, the eccentric resting on the spring leaded valve with bush for keeping the plastic ring tight, whilst adjustment is made

3.Is a Floatless and Jetless Carburetter in which the carburetter is made in three parts, the Body screwed for receiving the base and flanged for fixing to the engine and a Throttle telescoped on the body with two Air ports in the body corresponding to those in the body so that when the throttle is rotated all the air ports are closed and can be rotated to open them completely full bore. The Throttle is fitted between the Body and the Base. which also has a flat surface for a angled platform to be fitted.

4. Is a Floatless and Jetless Carburetter as claimed in claims i. 2. and 3 in which the Throttle having a flat surface has a moveable platform fitted with racks both ends for pinions fitting the centre of the platform has an elongated hole for the platform to move ineither diection and held tight by a bolt through the throttle casting and held tight by the tightening of a bush fitting over the bolt. The pin ions one each side for raising or lowering the platform in either direction, the spindle screwed and carrying the forked lever, the fork being over the screwed part of the valve and a washer laying on the fork is adjustable to correspond with the adjusted gradiant required the washer is then tightened with a nut. The long variable V grooved with long spring valve anchored just above the tapered end of the valve the taper resting on its machined taper. In ooperation the throttle is slightly rotated bringing the V groove in operation showing a fine spray of fuel at the same time opening the air ports slightly to correspond with the necessary requirements for faster excelleration. The adjustment for the main valve can be done two ways, one by adjustment of the washer on the forked lever, the other by raising the flatform to meet the spindle. The adjustment of the gradiant can also be made easy by having either side tight whilst the other side (pinionand centre bush are slackened thereby the pinion the tight side will swivel and not effect the raising of gradiant).

5. Is a FLOATLESS and JETLESS CARBU RETTER as claimed in the previous claims substantially as described in the specification
