Title: Improvements in and relating to Means for Opening Windows in Case of Fire or Emergency.
Inventor: WALSH EDWARD
Filed: 1899-02-14
Granted: 1899-03-25
Abstract: 3231. Walsh, E. Feb. 14. Window-opening apparatus.-In the event of a fire breaking out in a factory or the like, the sashes A can be opened by jets of water directed against hoods D which deflect the water down into troughs C fixed to the sashes. The sashes are glazed with wire glass, which retards the spread of fire, and cannot be broken by a stream of water from a hose pipe. A hole c in the trough allows the water to escape slowly.
Patent GB-189906211-A (GB)
Title: Improvements in and connected with Worm Gearing and in its Arrangement in connection with Elevator Apparatus.
Inventor: HOFFMANN ERNST GUSTAV
Filed: 1899-03-22
Granted: 1900-03-03
Abstract: 6211. Hoffmann, E. G. March 22. Worm gearing.-Fig. 1 shows a section of a worm 2 and rack 6. The teeth of the rack are made up of rollers 3 mounted with ball bearings 12 on studs screwed into the rack. The blade 1 of the worm is shaped to engage with the rollers as shown. In addition, the edge 4 of the blade is made with parallel sides to enter transverse slots 5 cut in the rack. Engagement takes place in the event of the rollers 3 breaking. The studs are screwed with differently-pitched threads at 10 and 11, so that they jam when screwed in. In the case of worm-wheels, the rollers 3 may be fixed to the sides of a peripheral channel in which the worm works, the blade also engaging with teeth 4 cut in a central projecting edge. To secure simultaneous contact of the rollers on the two sides of the channel, the wormwheel may be made in halves able to rotate relatively to one another through a very small angle. The same result may be secured by making the worm as a sleeve free to rock slightly on its shaft. For use with lifts, two worms may be mounted on the bottom of the cage and driven by an electric or other motor, the racks being secured to the sides of the well. Braking may be effected by a disc engaging with a recess at one end of the worm.

Patent GB-190002790-A (GB)
Title: Improvements in Glass-blowing Machines.
Inventor: HEERDT HEINRICH WILHELM
Filed: 1900-02-12
Granted: 1900-03-31
Abstract: 2790. Heerdt, H. W. Feb. 12. Delivering molten metal; shearing; blowing and moulding bottles.-Relates to glass-blowing machines for the manufacture of bottles. Fig. 1 shows a front elevation of the machine, and Fig. 3 a view of the work-table in plan. An inverted press-mould 11, Fig. 9, is supported in a socket 13 in the centre of the work-table, the press-ring 38 being removed. The operator takes glass from the pot on a punty which is held above the mould, and, when the latter is filled up to the bottom of the cavity left by the removal of the press-ring, the glass is cut by shears 58, Figs. 3 and 7. The shears are operated by admitting compressed air to a cylinder 62, thus turning the lever 59 on its pivot 59<a> and advancing the rod 56, which supports the shears, towards the mould. The lever 59 terminates in a rhomb-shaped cam 63, Fig. 3, which enters between the arms of the shears when they are over the mould and closes the blades so as to shear the glass. The press-ring 38 is now placed in position, and air is admitted to the cylinder 5 so as to depress the rammer 6 and compress the glass in the mould. The mould-hinges 42 support a roller 44 free to move on tracks 47, and a pair of semi-cylinders 46 on the mould-handles 45 constitute a second roller which can move on the forward tracks 47<a>. By opening a valve 53 air is admitted to a cylinder 52 so as to lift the tracks 47, 47<a> and raise the mould clear of the socket 13. The mould is then rolled on the tracks either to the right or left so as to bring it above one of the spring-pressed mould bottoms 14 and at the same time bring the neck end uppermost. The rails having descended, air is admitted to the cylinder 7, causing the descent of the forming-tool 8, which is made to rotate while descending by the co-operation of a helical groove with a pin projecting from the piston-rod. The tool 8 shapes the interior of the neck, and produces a cavity in the moulded mass of glass. After the tool has been withdrawn, the mould is opened and the parison is transferred by tongs to one of the blowing- moulds 12, which is not entirely closed until the blow-head 10 has been lowered and the bottle partly blown. The blow-head is spring-pressed by springs 29, and the air valve 33 is automatically opened by the descent of the hand-lever which lowers the blow-head. The press-moulds are cooled by continuous currents of cold air issuing from the nozzles 54.

Granted: 1901-10-18
Abstract: 18,613. British Thomson-Houston Co., [Lunt, A. D.]. Oct. 18. Converting alternating and direct currents; switches.- In order to minimize sparking at the commutator brushes and to obtain other beneficial results, the brushes are fixed, and the armature of the synchronous motor is advanced or retarded in accordance with the lagging of the current. This result is obtained by varying the field strength o the e motor. Fig. 1 shows an arrangement for rectifying the current obtained from a constant-current transformer T. The commutator 11 is driven by a synchronous motor 12, the field of which is excited by a direct-current generator A having field coils F, F<2>, the latter being in shunt with the working circuit L and its current varying with the load. Fig. 2 shows an arrangement for rectifying a current from a constant-potential source. In this case, the motor 12 has two field windings, the one 20 being in connection with the working circuit.

Filed: 1901-03-28
Granted: 1901-10-26
Abstract: 6520. Imray, O., [Henschel & Sohn]. March 28. Valve gear; compound engines. -Relates to hand-gear for starting, reversing, and varying expansion in compound engines. The object is to enable the grade of expansion in the high-pressure cylinder to be varied as desired, while the low-pressure cylinder remains unaffected, and yet to enable the gears for both cylinders to be reversed simultaneously. In Fig. 1, the gear is shown in side elevation. On the weigh shaft ware two arms, one a, on a loose sleeve, for reversing and regulating the expansion in the high-pressure cylinder, and the other h, fast on the shaft, for reversing the low-pressure cylinder. The arm h can be held by a spring latch g at either end of the sector d, and is connected by a slotted link s to the reversing-rod z. A pair of levers v are arranged to be operated by a roller on the arm a when it reaches its middle position, so that any further movement disengages the latch g. The attachment of the link s is at such a point that on continued movement of the arm a for reversal both the levers a, h reach the reverse position together.
