| 2 Nº 12,930.—A.D. 1914. Improvements in Carburettors of the “Internal Combustion Engine” Type. Figure 2 is an elevation showing the opposite side of the apparatus to that illustrated in Figure 1. Figure 3 is a sectional elevation of the tank and mixture container. Figure 4 is a cross section through A—B, Figure 3. Figure 5 is a sectional plan along the line C—D, Figure 3. 5 Figure 6 is an enlarged sectional view of one of the mixture tubes. Figure 7 is an end section through E—F, Figure 2. Figure 8 is a detail of the fabric-lined conduits. A petrol tank (1) of ordinary design is used, having the usual vertical partitions (2) dividing the lubricating oil and the petrol, a horizontal division (3) 10 forming the bottom of the petrol tank, and a cover for the container com- partment (4). The compartment (4) is divided longitudinally, preferably with metal partitions a little shorter than the length of the compartment; one end of each alternate partition (4A) and (4B) being attached to one end (4C) of the compart- ment, and one end (4D) of the intermediate partition (4E) is attached to the 15 opposite end (4F) of the compartment. The spaces between the said partitions are hereinafter termed “conduits”. The container comprises a series of these conduits inserted in the compart- ment (4) placed side by side; four of the said conduits are shown in Figure 4 numbered (5), (6), (7), and (8). Provision is made to line the conduits with 20 fabric, indicated at (9) made preferably from Turkey towelling, hereinafter called the stocking. The stocking is held expanded in contact with the interior surface of the conduits by any suitable means. One method shown consists of a bar (10) resembling in section the letter X, one length thereof being used for each conduit in the container as indicated in Figures 4, 6, and 8. The X shaped 25 bars are inserted within the stocking thus keeping the corners (10A), (10B), (10C) and (10D) in contact with the stocking and retaining it in a semi-stretched condition against the interior surface of the metal conduits. A method of con- structing the stocking is shown in Figure 8, (the view being broken at (G) and (H) to show the X shaped bars (10)), two fabric lined conduits being placed 30 side by side; (9A) represents a portion of the stocking (9) joining the two fabric lined conduits together; three of these portions (9A) would be required when there are four fabric lined conduits as illustrated in Figure 5. The portions (9A) may have short X shaped sections to maintain them normally stretched if desired. The inlet to the stocking is indicated at (11) Figure 2, the section 35 thereof developing from a square at (12) to a circular shape at the inlet (11) to enable a handy coupling being made with the atomiser (13). Precautions are taken in the event of an excess of petrol lodging in the container. The outlet pipe (4G) is produced to within the container as indicated 40 in Figure 1, and a suitable gauze cap (4H) is placed over the outlet. Apparatus is fitted between the container outlet (4G) and the cylinder of the engine, comprising a throttle (34), auxiliary air inlet (35) and a gauze chamber (36). The throttle and air inlet may be controlled in the ordinary way by a Bowden control having the usual levers mounted on the handle bars or in some convenient 45 position. The control connections are indicated at (34A) and (35A), Figure 1. Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:— 1.) In a carburettor, the combination of a device for atomizing liquid fuel 50 and mixing the same with air, a series of conduits connected to receive such atomized fuel and air and adapted to be connected to the intake of an internal combustion engine, said conduits being arranged side by side, linings of fabric within said conduits, and means to stretch said linings to conform with the sectional shape of said conduits. 2.) In a carburettor, the combination of a device for atomizing liquid fuel 55 and mixing the same with air, a series of connected conduits to receive the | ||
