Title: Improvements in Signalling Apparatus for use in connection with Winding Engines at Collieries, Mines and other Places.
Inventor: BOLTON CHARLES HARPER
IPC: B66B19/06
Filed: 1917-08-04
Abstract: 115,752. Bolton, C. H. Aug. 4, 1917. Signalling and indicating apparatus.-In colliery winding-engine signalling-apparatus of the kind described in Specification 18198/15 [Class 118'(ii), Signals], wherein a danger signal is exhibited when the reversing-lever is in the wrong position for safe starting of the engine, but is replaced by an all-right signal when the lever is moved to the safe position, arrangement is made whereby the. all-right signal is gradually obscured and a danger signal gradually exposed as the wind proceeds, the danger signal being fully exposed before completion of the wind. As shown in Fig. 1, two pairs of signals are provided used respectively in connexion with the ascent and descent of the cage, the danger and all-right signals 1, 2 of one pair alternating with the all-right and danger signals 3, 4 of the other pair. Only one pair of signals is uncovered at a time, the other being obscured by one of two shutters 6, 7, according to the position of the reversing-lever 9, each movement of which moves the shutters about an axis 8. In addition, a sliding shutter 10 is adapted to be moved by suitable connexion with the usual depth-indicator. As shown, the shutters 6, 10 expose only the all-right signal 3, so that the lever 9 is in the safe position for starting the engine. As the cage travels, the shutter 10 is moved from right to left by an arm 16 with a toothed sector 17 engaging a pinion on the spindle of the depth-indicator 11. The signal 3 is thus gradually covered and the danger signal 4 gradually exposed, being fully exposed just before completion of the wind. The signal 4 remains exposed until the lever 9 is moved, causing the shutters 6, 7 to expose the all-right signal 2 and cover the signal 4. During return of the cage, the shutter 10 moves to the right, covering signal 2 and exposing the danger signal 1. A sliding shutter operated by the reversing-lever may replace the oscillating shutters 6, 7. The signals shown comprise boards suitably coloured, say red and green, and provided, if desired, with coloured lenses illuminated from behind. In a modification, the signal comprises a rotatable lamp showing red above green at one side, and green above red at the other. The lamp is rotated 180 degrees at each operation of the reversing-lever so as to turn one or the other side of the lamp towards the engineman, according to the position of the lever. The shutters 6, 7 are omitted. A sliding or oscillating shutter operated from the depth-indicator serves to cover and uncover the danger or all-right portion of the exposed side of the lamp, according to the position of the reversing-lever.

Vacuum cleaners. -Means for actuatthe fan of a handoperated vacuum cleaner when the cleaner is stationary comprise a tubular axle internally screwed, in which a correspondingly screwed plunger is moved in one direction by a pedal &c. and in the other by a spring, the plunger being prevented from rotating in its operative stroke, so that the axle is caused to rotate. A free-wheel clutch causes the fan to be operated continuously during the to-and-fro motion of the wheels. The fan casing is provided with an extension B carrying a floor nozzle supported on rollers D and fitted with a brush, and an inlet b<1> for attachment of a flexible hose, and containing a hollow valve b<3> by which the floor nozzle may be cut off from the fan when the hose is to be used. The valve is moved by a pin b<4>, and the opening b<1> may be closed by a cup. The back plate of the fan casing carries a gear box E in which a worm a<3> on the fan shaft is driven by a wheel e<1>, and a pair of brackets F, F' to which the bail G of the handle is secured and which may rest on a stand M when the cleaner is lifted from the flow. The rear wheels H are carried on a hollow axle mounted in the gear box, the axle driving the wheel e<1> through a free-wheel device K. In the position shown in Fig. 1, the fan is rotated by a pedal N hinged to the extension B or other part of the machine, and connected by a chain P passing over a pulley mounted in the bracket F' and by wires p<2>, Fig. 4, lying in grooves in a rod R fixed to the bracket F, to a sleeve S sliding without rotation on the rod. A sleeve T is carried by sleeve S and is screwed to engage the screwed interior of the shaft J. The two sleeves have a certain lost motion, so that teeth on them engage on the down stroke only of the pedal. The sleeve T being thus prevented from rotating on this stroke, rotates the shaft J. A spring within the shaft returns the pedal. A ring k<2>, Fig. 11, is secured to the shaft, and carries rollers k<3> which in one sense of rotation grip a casing k<1> secured to the interior of the wheel e<1>. Washers on the ring k<2> co-operate with flanges on the casing k<1> to retain the rollers. The pedal drive may be replaced by a reciprocating handle.
