Abstract: 328,343. Peters & Co., Ltd., G. D., and Noble, E. C. Feb. 1, 1929. Auxiliary guide-wheels for railway traffic.- Road vehicles are adapted to run on rails bv the provision of subsidiary guide-wheels carried by arms or brackets attached to the axle in such a manner that they can be placed in and removed from the position in which they act as flanges for the ordinary vehicle wheels and when removed will not interfere with the swivelling or steering movements of the wheels. In the construction shown in Fig. 1, the two steering-wheels 2 run on rails 31 and are guided by rollers 5 carried on inclined axes 6 secured in the ends of arms 7, 20 mounted on the under side of the axle 1. The arm 7 is connected to the bracket 10 on the axle by a pivot pin 18 arranged at such an angle that the wheel 5, when moved out of action, swings into the position shown in dotted lines in which it is entirely clear of the road wheel 2. The arm 20 when in position, is rigidly clamped in taper brackets 21, 23 on the axle but is entirely removed when necessary. In the construction shown applied to the rear or driving axle in Fig. 2, horizontal pivots 27 are arranged at a slight angle to the centre line of the axle, as shown at Fig. 6, so that the guide-wheels 5, when swung clear of the rails are only moved slightly inwards, this being all that is necessary since the road wheels 2a do not swivel for steering. The brackets 7 may be held firmly in their operative or inoperative position by the pins 27 which are specially shaped for this purpose.

Filed: 1929-02-06
Abstract: 305,584. Naamlooze Vennootschap Gemeenschappelijke Mijnbouw Maatschappij Billiton. Feb. 7, 1928, [Convention date]. Regulating or controlling.-The operation of a centrifugal pump is regulated by the injection into the suction pipe of gas at a reduced pressure which remains substantially constant; air-lock in the suction pipe is also prevented by this means. The suction pipe j of the pump l dips into the pump k, and is connected by a T-piece h to a pipe g leading to the top part of a vessel a. A tube b is partly immersed in liquid supplied through the pipe c to a desired level in the vessel, the level being indicated on the gauge e. Inside the T-piece h a rubber tube p is attached to a nipple r in communication with the pipe g and secured to the member h by bolts and wing nuts. When the pump is working gas will be drawn in through the pipe g and tube p, according to the head in the suction pipe and the pressure in the vessel a. If the feed decreases, the level in the sump falls, the head increases and more gas flows into the suction pipe ; the capacity of the pump thus decreases until the liquid in the sump rises to the desired level. The tube being flexible will extend in the direction of liquid flow in thesuction pipe.

Filed: 1930-02-08
Abstract: 346,088. Studs. POWELL, S., 5, Slade Road, Little Sutton, Warwickshire. Feb. 8, 1930, Nc. 4284. [Class 43.] In collar and like studs, particularly of the type which are formed from a single metal blank, the metal which is to form the head of the stud is increased in thickness. In one form, Fig. 8, the metal blank is shaped into a cup wherein is placed a reinforcing cup 3. The finished stud is then produced by drawing and swaging so that the head 6 is reinforced by the cup 3. According to a further form, Fig. 10, the metal blank 7 forming the stud is pressed so as to reduce its thickness at the edge and increase it at the centre 8. As the metal of the centre ultimately forms the head, an increased thickness is thus obtained at that point.
