No. 10,744: Dated May path, 1904.W. J. Crossley, of Crossley Bros., Ltd. and J. Atkinson.—An internal combustion engine devised to give, with a single cylinder, one impulse for every revolution. The piston (A) works in a cylinder having a combustion end (C) and an exhaust valve (J), the port (I) of which is situated approximately midway along the length of the cylinder. The two ends of the cylinder are connected by a reservoir passage (D), controlled at the combustion end by a valve (El. Communicating with the lower end of the pipe (D) is an air inlet valve (F), and an admission valve (G) is provided and opens into the passage (D) at a point approximately half way along its length. As the piston advances towards the end (C) of the cylinder, air is drawn in through the valve (F) and gas, or, in the case of an oil engine petrol, through the valve G. During the following backward movement of the piston (A), effected by the explosion of a charge previously drawn in at the end (C) of the cylinder, this mixture behind the piston is compressed into the passage (D). As the piston (A) uncovers the port of the exhaust valve 0) the valve (E) opens and the mixture commences to enter the cylinder through a slightly spiral passage. As the admission valve (G) is situated a considerable distance along the pipe (D), air only will first enter the cylinder and serve to scavenger the same. The piston (Al now returns, and after passing the port (I) commences to compress the charge, the valve (E) being now closed. The charge is then ignited by an ignition device (H), and a fresh cycle of operations commenced. The spiral form given to the inlet passage from the valve (E) is for the purpose of circulating the mixture at that end of the cylinder remote from the crank shaft.
No. 10,467: Dated May 6th, 1904. J. Pickbourn and J. J. Cooper.—This invention is for a valve for a boiler watergauge, and has for its object to enable the wearing parts to be readily renewed. The valve is provided with a plunger (d) operating upon a seating (e). The plunger has at its outer end an annular groove (1) adapted to receive the claws of an engaging member (j). The member (j) is carried by a screw-threaded spindle (k) having an operating wheel (pi), and the spindle is mounted in a clamping member (1) pivoted to the body of the valve. When the operating end of the plunger (d) becomes worn it is only necessary to swing the clamping member (1) out of alignment therewith, as shown in dotted lines in Fig. t, and the plunger can be withdrawn for the purpose of replacing it by a new one.
No. 10,335 Dated May 5th„ Igo+ F. Humphris, Shepherd's Bush, London.— A steering pillar according to this invention is carried in a plate (A) pivoted at al. The plate is provided with segmental slots (a2), which engage suitable pins, so that the rake of the steering pillar may be adjusted within certain limits. The
lower end of the pillar carries two pulleys (b, bl), and these engage cords (62, 0) fastened to lugs (el) on a connecting rod (CI. The rod (C) is free to slide in a guide (c), and is connected at its free end to the steering axle of the vehicle. An interesting feature in this device is the shape of the grooves in the pulleys (b, bl), these being of such form that, whatever the position of the pulleys, the cords (b2, 61) are always fed off at approximately the same angle.
No. 11,613: Dated May 20th, 1904. P. W. Noble, Swindon.—According to this invention single or multiple cranks may be readily built up from a numberof parts, all of which are alike. Each part consists of two sockets (A and B) connected together by a wedge (C). The socket (A) has claws (DI on one end adapted to engage corresponding claws on a second member (A). The cranks are built up by connecting two (B) sockets together by suitable bolts and nuts (E), and a second crank may be added by two other members similarly built up and connected to the first pair by other bolts and nuts, the claws of the two (A) members in this case being made to engage.
No. 2o,o60 : Dated September 17th, 1904. J. Oldfield, R. Oldfield, and R. A. Oldfield, Birmingham.—This specification describes a lamp for automobiles having a false bottom (A), upon which the reservoir (F.) is carried. The bottom may conveniently comprise two grooved strips, as shown at al (Fig. 2), and is supported by springs (C). The strips conveniently carry vertical supports (c2), which slide in suitable guides (b3). This device is said to considerably increase the stability of the light.
A conference of the Metropolitan Paving Committee with representatives of the corporation and metropolitan borough councils was held on Friday at the Westminster City Hall, for the purpose of considering the question of the interference with the public streets resulting from the constant inspection and repair of their works by the Postmaster General and the electric light and other companies. A resolution was carried in favour of a Bill being introduced by the Government, embodying model clauses for the better proter tion of the local authorities.
