ALBION Marian Can CO., LTD., and T. B. Monnay, No. 2252, dated 28th January, 1914.—A six-cylinder two-stroke engine is described in this specification.
Three of the cylinders are working cylinders and three are pump-cylinders and the arrangement is such that rotational balance is practically complete. A working cylinder and its pump are arranged as a unit, three of these units being grouped together and arranged so that any or all of them may be cut out or let in under varying loads. In the accompanying drawing the left-hand cylinder of each unit is the pump cylinder and the right-hand the working cylinder, and the two cranks in the middle are coincident, the next adjacent pair are coincident, and the outer pair are also coincident. to give the required balance. This arrangement puts some of the pumps out of phase with their working cylinders and the main feature of the invention is illustrated in the right-hand unit, in which the passage between the pump and the working cylinder is made much smaller than in the other cases, because the pump-crank is 120 degrees in advance of its corresponding working crank.
H. E. Duminat, No. 669, dated 9th January, 1914.—This engine is designed to use two different kinds of fuel.
In the construction illustrated the working cylinder is provided with an annular air-pump between it and the crank chamber, this air pump supplying a working Gylincler the piston of which is moving in opposition to that. of the pump. A partial charge of ordinary carburetter air is introduced through the automatic inlet valve at the top, and simultaneously a charge of heavy oil is introduced through the injector at the left-hand side of the cylinder about the middle of its length. This injector is worked by compressed air and it is preferably arranged to supply a certain amount of water in addition to the heavy oil. F. A. WarLis, No. 26,653, dated 20th November, 1913.— This specification describes a plough Ivhich earl be used if desired as a tractor.
A single driving wheel at the rear is used, and the pleuih share is arranged directly in front of this, so that the driving wheel always runs on the hard ground at the bottom of the
furrow which is being turned. The front axle, which carries the steering wheels, is connected to the frame in such a manner that its height can be adjusted to any required extent. The two front wheels are spaced apart to such an extent that one of them runs on the unploughed ground and the other runs in the previous furrow, and it may be suitably shaped for pressing this. The bottom of the furrows is practically on a level with the unploughed ground, so that no vertical adjustment is needed of the front wheels relatively to one another, and this machine can open up furrows of any length.
C. E. S. •CLENCH, No. 15,696, dated 29th June, 1914.—This specification describes a modified construction of ClaudelHobson carburetter for using paraffin or other heavy fuel. A butterfly valve is provided in the air inlet and is coupled up -with the throttle, so that when the throttle is in its closed or nearly closed position this valve also is closed. Considerable suction is thereby caused in the lower part of the air inlet, and this renders the lower set of orifices operative to produce an increased suction on the jet.
The two valves are coupled together by segmental racks which can be arranged to give any desired relative movement of the two. It is preferable to arrange that the movement of the a,ir valve should be more rapid than that of the throttle, and that when tho air valve has been fully opened its engagement with the throttle should be broken, so that further movement of the throttle is possible. The accompanying drawings show an arrangement which permits of this.
