Abstract: 26,875. Graham, H. B., and Beeching, F. W. Dec. 5. Gas and explosivevapour engines.-Relates to an arrangement of vaporizer and admission valve to prevent premature ignition when a high compression is used. The vaporizer is removable so that an extension of the combustion chamber may be attached to enable the engine to be used as a gas engine, the aperture for receiving the ignition tube being covered by a blank flange when the engine is using a liquid hydrocarbon. The vaporizer b has a number of pockets h formed by ribs g between an inner tube f and the casing e, through which the rich mixture is drawn in a circnitous path before passing through a valve o and igniter passage i to be mixed with air supplied by the valve c. During compression, the portion of the charge compressed in the passage i is returned over the air valve c, and is thus cooled so that it may be more highly compressed. Liquid hydrocarbon is supplied through a central tube k, and a variable quantity of air is drawn in through a grid i<3>. The valve o is controlled by the governor. The vaporizer is initially heated by a lamp, and an ignition tube p may be used, but when using gas, the tube is inserted in the aperture covered by the blank flange q.

Granted: 1905-02-23
Abstract: 9373. Hills, A. F., Urquhart, D., and Honey, A. E. April 23. Brush-holders.-Relates to detachably securing the brush-holder to the carrying-spindle, and to means for obtaining a firm pressure between the brush and the commutator: The carbon brush c, coated with copper and provided with a flat brass plate d, is mounted in a holder a, electrical connection between the two being effected by a flexible conductor f, attached to the holder a by a split plug h and to the plate d by a screwed pin g. The holder is secured to the carrying-spindle by the grooved lug i and hinged cap j, the locking being effected by the hinged screw k and wing-nut l. The Provisional Specification states that the cap j is furnished with a screw which penetrates the spindle, thereby preventing the rotation of the holder about the spindle. On the other side of the holder are two lugs o, which support a pivot pin n on which is mounted an arm m. One end of the arm is adapted to bear on the brush c. A spring q, coiled on the pin n, has one end fixed and the other end adapted to engage with either of the slots r cut in the flange s on the arm m. The tension of the spring can therefore be varied at will, and, consequently, the pressure with which the brush bears on the commutator. When the brush is lifted from the commutator into the position indicated in Fig. 1 by dotted lines, the arm m bears against the side of the brush c, and thereby secures the brush in its raised position.

Title: Improvements in Gill Drawing or Roving Frames for Flax, Hemp, Jute or the like.
Inventor: WALKER SAMUEL
Filed: 1904-05-10
Granted: 1905-02-09
Abstract: 10,810. Walker, S. May 10. Gill boxes or frames.-Relates to gill drawing or roving frames for flax, hemp, jute, &c., and the object is to render each head of the frame independent of the others, so that any one head can be stopped, either by hand or automatically, when an end breaks, or started without affecting the others. The main shaft 5 extends throughout the length of the machine, and drives each head through a clutch 22, 23, of which the sliding and rotating part 23 can be operated by the starting- lever 26 or by the lever 29, 28 of the stopmotion. The loose part 22 of the clucth is connected to the several parts of the corresponding head by suitable gearing, which is situated between side frames in which each head is enclosed. When the machine is working, the clutch lever 29, 28 is looked by a spring catch 50. To stop the head automatically when an end breaks, a horizontally-reciprocating bar 46 carries a spring frame 43, 44, 34, of which the horizontal bar 34 normally misses the end of the catch lever 50, but, when an end breaks and one of the spoon detector levers a or b falls, one of the arms 43 or 44 engages with its corresponding detector lever and the bar 34 moves further than usual so as to disengage the catch lever 50 and liberate the weighted clutch lever. When the bar 34 retires, the spring 49 draws the catch lever 50 forwards, so that its lower end 30 engages with the depressed arm 29 and forcibly disengages the clutch.
