Title: Improvements in Railway Block Telegraph Indicators.
Inventor: BLACKALL ALFRED THOMAS
IPC: B61L23/12
Filed: 1913-06-06
Granted: 1914-09-06
Abstract: 13,157. Blackall, A. T., and Jacobs, C. M. June 6. Signalling-instruments.-A rotatable polarized armature is caused to assume one of three different positions by the establishment of one or other of three different conditions of magnetic field, and is retained in position solely by the magnetic retentivity of the cores of the field magnets. The armature e<1>, Fig. 1, is polarized by the coil e<2>, which is connected in series with the battery f. The armatures of the relays g, i complete the circuit to earth and to one of the coils a, b, c, and the current then divides through the other two coils in parallel and to earth, and thus produces three distinct conditions of magnetic field. In a modification, two field magnets, magnetized oppositely or similarly, are employed, but a third may be added for use when the two main cores are similarly excited. In each arrangement, the armature may have some axial play so as to be pulled on to the core to prevent rotation until the current is cut off, and to be moved only by the remanent magnetism. Specifications 17,772/05 and 19,603/09, [Class 38 (v), Electric switches &c.], are referred to.

Inventor: CHILD GEOFFREY HERBERT
Filed: 1913-09-05
Granted: 1914-07-23
Abstract: 20,041. Child, G. H. Sept. 5. Spring power-storing mechanism.-An engine is started by two or more springs 6 connected at one end to a box 2 and at the other end to a sleeve 5, the springs being wound up from the engine shaft through the clutch 8 and the shaft 7, on which is mounted an eccentric 20 carrying an internally toothed wheel 19 gearing with a pinion 13 fast with the sleeve 5. During winding, a projection 21 on the wheel 19 bears against a roller 22 on a disk 23 so that the wheel cannot rotate but drives the pinion slowly; the pinion drives, through an idle wheel 14, a box 15 which turns a nut 16 on a fixed screw 17 to move the disk 23. at the end of the wind and remove the roller 22 from the path of the projection 21. A spring 18 on the screw causes complete disengagement. The spring is held in its wound condition by pawls on a plate 10 engaging ratchet teeth 9 on the sleeve 5, the plate being held by a band brake 11. With the spring wound to start the engine, a pedal is depressed which first moves a projection, not shown, in front of the plate 23 to hold it in the position shown and then releases the brake 11. The springs then drive the shaft 7 through the pinion, internally toothed wheel, pawl 27 carried by the wheel, and ratchet-wheel 20 on the shaft. To wind the spring or start the engine by hand, the shaft 7 projects outside the casing. The casing is made in two parts separated by a plate 3. The Provisional Specification also describes an arrangement in which the eccentric carrying the internally toothed wheel is mounted on a sleeve which carries spring-pressed pawls engaging ratchet teeth on a shaft connected to the engine. A nut surrounding the sleeve moves axially thereon, and at the end of the rewind acts on the pawls to disengage them from the ratchet-wheel.

Title: Apparatus for the Separation of Finely Divided Solids from Liquids.
Inventor: DORR JOHN VAN NOSTRAND
Filed: 1914-06-04
Granted: 1915-08-04
Abstract: 13,606. Dorr, J. van. N. June 5,1913, [Convention date]. Decanting and settling. -Apparatus for waterconcentrating ores or otherwise separating finely divided solids from liquids by settling comprises a number of superposed shallow trays of individual depths such that the settling zone is located directly beneath the zone of surface current or flow of disturbance, the trays having orifices through which the sediment is moved by sweeps or the like into a common exit conduit without passing through or into the settling regions of the other trays. A suitable depth for the trays is three feet or less. In the form shown in Figs. 1 and 2, the stationary circular trays B are supported in a tank A having an overflow launder a for clear effluent and an exit a<2> for the concentrated slime. The material to be treated is preferably fed to the trays through perforated rings O<1> and valved pipes O leading from a conduit N terminating in a box N<1>, which is provided with gates n corresponding to the number of trays. The bottoms of the trays are preferably coned, as shown at F, and a rubber packing L is used to prevent inward or outward leakage. The packings bear on the split bosses I of the bladed sweeps g, which are clamped on the central, rotary, tubular shaft D. This shaft has openings d, and the sweeps are so shaped as to urge the solid matter through these openings to the common exit a', while the clear liquid passes over the edges of the trays and finally flows away at a<1>. Settlement also occurs in the tank A, the residue being collected by a bottom sweep M ; but the tank may be omitted, as shown in Fig. 8. In this form, each of the tanks S has a launder s for clear effluent and a central outlet U for solids. The perforated annular inlets Z are carried by the frames Y which support the sweeps and are clamped to the shaft W traversing cylindrical extensions S' of the tray bottoms. The arrangement shown in Fig. 1 may be provided with conical trays, and these, as shown in Fig. 6, may have separate valved outlet pipes R passing through the shaft D', which is fitted with a mercury seal at the bottom of the tank. In the form shown in Fig. 10, rectangular trays 1 are employed with iulet and outlet launders 3, 4 at their ends and valved exits 17 for the solids, which are collected by gear-driven endless sweeping- belts 15. An arrangement of oblique trays in a containing tank is shown in Fig. 11. The reciprocating sweeps 25 have arms 33 passing through slots 34 to rods 27, which are oscillated by a cam 29 and linkage 30, 31, 32. Aprons 23 prevent the incoming material from mixing with the thickened discharge from the trays, which passes away at 24. The aprons may be extended to the adjacent wall of the tank, and separate discharge pipes may be provided for the trays. In any of the tank arrangements, test cocks Q may be provided, so that if the discharged liquid be cloudy, the region in which the working is abnormal may be readily located.

Granted: 1915-12-23
Abstract: 24,555. Brooke, Bond, & Co., and Walker, G. T. Dec. 23. Guillotine type.-In paper and like cutting machines having a feeding-fence movable step by step so that cuts may be made at regular distances apart, duplicate means are provided for moving the fence two predetermined distances, and means are also provided for selecting which of such duplicate means are to be operative for determining the distance the material is to be fed. As shown, the fence 7 carries a pair of racks, rods, or their equivalent 18, 18<a>, with the teeth or studs 21 of which are adapted to engage pawls 46 upon an arm 44 connected to a hand-lever 35. The pawls are normally held in operative position by springs 51, but by means of cams 50 controlled by handles 49<a>, either pawl may be tilted and held clear of its rack during the time that the other is in use. For bringing the fence back to its starting position (shown in broken lines in Fig. 1), it is connected by a cord 9 to the pulley 11 of a hand-wheel 12, and the starting positions of the racks may be longitudinally adjusted by turning handles 30, whereby are actuated shafts 26, toothed wheels 28, and internally-threaded toothed wheels 23 upon the screwed ends 17 of the racks. To limit the throw of the hand-lever and so prevent the pawl from being moved backward to such an extent that it passes over more than one stud upon a rack, a removable pin is inserted into one or other of the holes 37 in the guide 36. In its forward movement the pawl engages behind a stud and so carries forward the rack and fence until the pawl engages a fixed stop 20 through which the rack passes. Screwed rods, with adjustable nuts to serve as studs or abutments for the pawls, may be used in place of racks. According to the Provisional Specification, the pawls are brought into engagement with the teeth or racks by a cam and are withdrawn by spring or like action,
