CLAYTON AND CO., LTD., and J. W. JEKMISON, No. 7846, dated 27th May, 1915.—The accompanying drawing shows diagrammatically the construction of a road-sweeper. The usual receiver for the sweepings is situated at the back of the vehicle, and the front is occupied by a cylindrical casing within which a large brush revolves. The road-sweeping brush is arranged underneath and delivers the sweepings on to a hinged or flexible flap, or into the cylindrical casing in which it is carried round by the large brush to be deposited
in the receiver. • The large brush need not be in actual contact with the cylindrical casing, so that, there is no need to provide for radial adjustment of the brush-stocks.
A. Wrivrox, No. 10,309, dated 15th July, 1915.—This specification describes, in detail, the lubricating arrangements for an engine in which the supply of oil is made to vary with the speed of the engine. The -accompanying drawing shows the essential parts of the mechanism by which the control of the quantity of oil is effected. A multiple pump, part of which is indicated on the lefthand side, is supplied through a special valve shown on the right-hand side. The driving spindle for the pump plungers is formed at its right-hand end with a spiral pinion engaging a long spiral pinion which is keyed onka. vertical shaft so that it can slide up and down. This vertical pinion tis connected to a governor so that variations of the engine speed cause such upwards or downwards movement.
The lower end of the shaft carries a rotating plate valve which controls communication from a supply reservoir to a number of radial ducts, each of w.liich forms the inlet to one of the pumps. The valve is rotated by the driving shaft for the pumps, and any change in "engine speed, by moving tte vertical spiral -pinion, gives it an additional rotation'by which the cut-off of the controlling valve on the oil inlets is advanced or retarded as required.
L. T. DELANEY, No. 7086, dated 11th May, 1915.—The object of this invention is to sinzplify the construction of trailers particularly as regards the mounting of the draw-bar. 'ilia end frame-members, or one end member if the trailer is not to be reversible, is curved about the king-bolt or pivotal axis of the drawbar. The drawbar, in addition to its pivotal mounting, has balls, rollers or other anti-friction
members engaging the curved frame-member to guide its outer end. Any desired connection may be povided between the drawbar itself and the wheels to`effeet the steering in the ordinary manner. ' A further advantage gained by adopting this arrangement is that, in the event of more than one trailer being employed, they are kept in contact and can be reversed with ease.
TEE BRITISTI VITEETINCROUSE ELECTRIC MANI:MAC:TURING CO., LTD., NU. 100,197, dated 24th .March, 915.—Electric starters have been made in which the armature is moved axially to engage or disengage the driving pinion and, the flywhiel, The weight of the armature, however, is so great
that before the axial movement takes place it has attained a rotational speed sufficiently high to interfere with the meshing of the gears. According to'this invention the axial movement is given. only to the armature shaft and pinion, the shaft sliding through a. sleeve which carries the armature. A magnet, mounted on, the end of the motor frame in series with the motor, effects this movement. The shaft is comparatively so light that its axial movement is effected before the armature gains any appreciable speed, so that the meshing of the pinion with engine flywheel is easily effected.
