THE ALBION. MOTOR CAR CO., LTD., and T. V. MURRAY, No, 13,803, dated 8th June, 1914.—In flexible couplings of the type using sheets of steel or leather connected to alternate arms of two spiders, it is found that they are not satisfactory
if the want of alignment is considerable owing to the excessive flexure.
According to this invention the number of flexible members is increased proportionately to the want of alignment of the shafts, so that no single member becomes unduly flexed. Each of the shafts carries a spider, and a series of rigid. floating members is arranged between the spiders, being connected by. flexible members to them. Each rigid member must be held at not fewer than four points; it is conveniently connected at. two points to the flexible member on each side out.
THE DA.T.MLER CO., LTD., and A. E. BERRI-RAN-, No. 5818, dated 7th March, 1914.—This device is used for injecting a measured amount of petrol into the induction pipe of an engine.
.A small measuring chamber is connected to the petrol supply and to the induction pipe by a three-way cock., .which permits the chamber to be put into communication with either pipe, but prevents the two pipes being connected together.
A simple arrangement of levers provides for operation of the de.vice by a, pedal at the dashboard. When the pedal is pressed seine petrol flows into the measuring Chamber and compresses the air in it. It is immaterial how long the pedal be depressed, as the receiver being of limited capacity can , only contain a predetermined amount of fuel. When the pedal is released the petrol is forced out into the induction pipe; the device may be operated as frequently as desired, and needs no other Manipulation.
THE LACRE MOTOR 0.+S.E CO., LTD., and J. S. DREWRY, No. 18,514, dated 10th August, 1914.—The accompanying drawing shows diagrammatically a carburetting and vaporizing device. suitable for use with heavy oils. The arrange merit is intended to give automatic variation of the mixture according to the speed of the engine. The float-feed-chamber on the left is provided with a small air inlet in the form of a U-tube, and the fuel enters the U-tube at the bottom and passes thence into an exhaust-heated induction pipe of some considerable length. An air inlet is provided on this pipe so that the air drawn in acts as an injector to draw the fuel in. This air is insufficient to give complete combustion and additional air is provided for by an inlet at the outer end near the engine. A valve controls these two passages where they meet. The extra length of the mixture induction pipe causes the mixture to be richer at low speeds than at high speeds, and the U-shaped feed tube in the float. feed Chamber allows the fuel to enter in a constant stream when the suction is light. These two effects are arranged to vary the strength of the mixture according to the speed.
A. HERBERT and P. V. VERNON, No. 13,748, dated 6th Juno 1914.—Diffieulties arise in the lubrication of machine tools on account of the pipes choking up with chips or waste, particularly so when flexible tubing has to be used.
According to this invention an open trough is fixed on the standard of the machine, and the gutter on the table is made to deliver into this trough whatever may be the position of the table.
The trough is preferably semi-circular or U-shaped, but it may consist of a _pipe with a slot down one side, and it is preferably sloped slightly from the vertical so that, any liquid delivered from the table fails an to it, whether the flow be rapid or slow.
