Abstract: 187,227. Wasmundt, W. de., (Assignee of King, M.). Oct. 12, 1921, [Convention date]. Driving-gear; engines with main shaft parallel or inclined to axis of cylinder; revolving-cylinder and reciprocating-piston type; radialcylinder engines.-An engine is provided with cam driving- gear, the cam curve of which is constructed so that the piston pressure is always normal to the bearing surface which may be an involute are of a circle, or a series of arcs of circles, or other similar curve. Various geometric constructions for finding curves suitable for two or four-stroke-cycle fluid-pressure engines are described. A revolving, tangential-cylinder engine with a track shaped as shown in Fig. 9 is shown in Fig. 16. The pistons 6 carry rollers which may be mounted in ball-bearings 10, Fig. 18, and the distribution is effected by cylinder ports 11 alternately registering with pressure and exhaust ports 14, 15 in the casing. The pistons press normally on the parts b, c and b<1>, c<1> during the power strokes. In a four-stroke cycle engine, the centre of the drum may be disposed so that the compression stroke is less than the exhaust stroke, or the expansion stroke is increased, or both effects are produced', as shown in Fig. 19. Or the desired result may be obtained bv modifying the cam tracks. In Fig. 20 the deleterious tangential component of the piston's pressure on the driving-cam is eliminated by the interposition of a rolling lever 27 pivoted at a to the piston, the other end of the pivot b sliding in a groove 29. The Specification as open to inspection under Sect. 91 (3) (a) comprises constructions of revolving, inclined-cylinder engines wherein the pistons are held by centrifugal force against face cams on central shafts. In Fig. 25 (Cancelled), pins 23 in the pistons bear on a ring mounted on an inclined track by a ball bearing. This subject-matter does not appear in the Specification as accepted.

Potato planters. - In a planting-machine in which potatoes &c. are dropped from a drum constituting one of the supporting-wheels and having circumferentially arranged cells, openings are provided at both sides of the cells to allow of inspection and to admit the potatoes. Scoops may be arranged alternately on opposite sides of the cells, and the scoops and cells may be adjustable in size. The drum shown in Fig. 1 consists of two circular disks 32, concentric cylindrical walls 33, 34, and radial partitions 35, the outer wall 33 being formed with openings 37 and the disks 32 with apertures 38. Scoops 40 take up single potatoes from two receptacles at the sides of the drum and pass them through the openings 38. Spades 43 are fixed on the drum. In machines having three dropping-drums, the outer ones have scoops on one side only. In a modification, the drum consists of two cast-iron sections secured together and cast with concentric circular ribs and with radial ribs which together form the distributing-cells. The scoops in this case are provided with T-shaped shanks which fit into slides in the drum. In another modification, each side of the drum consists of two concentric disks with an annular space between them, as shown in Fig. 9. The potatoes may be delivered continuously through the annular space by a screw conveyer; or scoops may be mounted independently of the drum and may be driven at a higher speed. The lower part of the annular space may be covered by an inner wall of the receptacle from which the potatoes are taken by the scoops. A brush may be provided to push the potatoes from the scoops into the drum. The cells of the drum shown in Fig. 9 are adjustable in size. Each radial wall 35<3> is made integral with a rearwardly projecting guide piece 48 and with a front plate 49, and is adjustably fastened to the concentric disks 32<4>, 32<5> by screws 50 in screw holes 51.

Abstract: 893,038. Indicating liquid levels. VERMOHLEN, M. A. Aug. 13. 1959 [Aug. 18, 1958], No. 27751/59. Class 123(1). A simple and reliable low-level signalling apparatus for pressure vessels such as a boiler 1 comprises a pipe 2 which is attached externally to the boiler at a level corresponding to the lowest permissable water level and which is sealed at its upper end by a detachable housing 3 which is made of non-magnetic material and accommodates a bimetallic rod 4 which initiates the warning signal. As shown in Fig. 1 the bimetallic rod 4, mounted at its lower end on a housing cross piece 5, carries, at its upper end adjacent the top wall of the housing 3, a permanent magnet 6 which influences the moving contact 7<SP>1</SP> of an electric switch having a fixed contact 7. At normal level water partially or completely fills the pipe 2 and the bimetallic rod 4 takes up a vertical position as shown. A sudden rise in the temperature, due to the introduction of steam into the pipe 2 when the water level falls below the permissable level, causes the bimetallic rod 4 to deflect sharply in the direction of the arrow F the magnet 6 urging the movable contact 7 into engagement with the fixed contact 7 to complete the circuit for the signalling and controlling apparatus. In a modification, Fig. 3 not shown, a bimetallic rod, on a contact thermometer, is housed in a coaxial recess which extends downwardly within, and from the upper end of, the housing 3.
