Abstract: 294,764. Robertson, J. M. July 14, 1927. Exhaust - silencers.-The silencer comprises a casing 1, Fig. 1, containing a number of spiral passages through which the gases flow in series. The interior of the casing is divided by partitions 2 into compartments, each of which contains a pair of helical baffies 3, 4. The gases enter tangentially at 8, and are swirled to the centre 6, whence they pass through a hole in the partition 5 to the centre of helical baffle 4, the blades of which are perforated. They then pass outwardly and are directed by baffles 7 on partition 2 into the outer passage formed by the baffle in the next compartment, whence they again flow in the manner already described. From the last spiral passage they pass through holes in a conical baffle 15 to the outlet 9. A similar conical baffle 17 may be provided at the inlet end, and holes 19, 20 in the partition 2 permit of a short passage of the gases to the centre space 6. The baffles and partitions are. held together and secured to end caps 10, 11 by a bolt 14 and) nuts and may be withdrawn as a unit from the casing 1. which is slightly tapered to facilitate the withdrawal. In a modification, Figs. 4 and 5, the casing 21 is of oval or rectangular cross-section and a number of spiral baffles 22 are arranged in series with their planes along the axis of the casing, instead of at right-angles, as in Fig. 1. The spiral baffles are welded between side plates 23, Fig. 5, each having holes 25 corresponding to the central spaces of the spiral baffles. Inclined baffles 24 are also welded to the plates 23, which have notched openings 26 along their lower edges. The exhaust enters at 27, is swirled to the centre of the first spiral baffle, then leaves by holes 25 to the side passages, whence it is deflected by the baffles 24 to notched openings 26 and the outer passage of the second spiral baffle, and so on to the outlet 28. The spiral baffles, side plates, and inclined baffles constitute a unitary structure held in place by pairs of bolts 30, 31 and easily withdrawn from the casing. The silencer may comprise only two spiral passages, the gases entering the outside of one and flowing from the centre thereof to the centre of the next. According to the Provisional Specification, ejector nozzles may be fitted in the disc partitions to facilitate the passage of gas from one compartment to another.

Abstract: 246,884. Haward, E. W. Aug. 11, 1924. Lateral-splash guards. - Relates to splash guards for the wheels of road vehicles and of the kind in which a shield or plate-like member is hinged alongside the wheel and is adapted to move upwardly and outwardly when meeting an obstruction end-on. The guard is carried by supporting arms secured to a carrier by the pivot of the stubaxle in the case of a steering wheel or the suspension spring in the case of a rear wheel, the guard being mounted on an axle in short links pivoted to the supporting arms. The guard is free to rotate about its axle outwardly and upwardly from a position slightly out of the vertical, but is restrained from moving inwardly, while the links and guard are free to move bodily about the pivots of the links. The guard b, of paper pulp or fibre reinforced by sheet metal, is furnished with a flexible flap e at its lower edge and carries at each end a metal plate d formed with a curved or inclined tapered roll d'. The guard b, Figs. 2 and 4, is clamped between a pair of half-round bars a<1>, a<2> which constitute the axle of the guard and are rotatably mounted in links h<1> pivoted in the forked ends of arms i clamped as shown, to the rear suspension spring at m. The upper edge of the guard is bent inwardly as shown. The guard b is held in a slightly outwardly inclined position by the engagement of a cam on the axle a<1>, a<2> with a pin k on the link h<1>, the upward rotation of the links being limited by the bottom of the bifurcations in the arms i. The axle normally rests against the arms i and a cotter l, Fig. 2, prevents withdrawal of the axle from the links. In the modification shown in Figs. 13 and 16, the supporting arms i<1>, i<2> are of tubular formation and carry T-shaped blocks i<3> which slide, under the action of springs m<5>, m<6>, in boxes m<2> secured to the suspension spring or to the stub-axle pivot as the case may be. The cam j and stop pin k previously described are replaced by a curved plate d<2> adapted to engage the end of the supporting arm i<1> to hold the guard in its normal inclined position. The axle of the guard, in addition to its movement of rotation in the links h<3>, is free to have a limited longitudinal movement against spring action, withdrawal of the axle being prevented by pivoted catches a<3>. One of the Provisional Specifications describes the axle of the guard as being mounted directly in a frame constituting the supporting arms, while another describes spring devices, such as spring controlled pin anl slot connections between the links and supporting arms, to prevent damage if the guard meets an obstruction broadside-on.
