Granted: 1903-02-26
Abstract: 9877. Nesbit, D. M. April 29. Air, supplying, methods of; air, heating &c.-Air is admitted at a height of six to eight feet above the ground level, and then passed down a passage within a recess or casement, through filtering- media, and led up around air-heating appliances, such as radiators, before being allowed to escape into the space to be ventilated. Fig. 3 shows a sectional elevation of apparatus arranged in this way and placed in a casing fitted, if desired, with locked doors. The inlet grating appears at a, the down-cast at b, the filter at e, the heating-coils at d, and the outlet at k. The entry of air may be regulated by the valve f. A further outlet is provided at h when rapid circulation of air is desired. This selfcontained, above-ground apparatus may form part of a trunk line of conduits, in which case the air, by means of a valve, is passed either through the heating-chamber or through the recess behind. The supply of air from the trunk may be also regulated by a series of valves or louvres, which are pivoted to a rod so that, on a movement of the rod, the valves are simultaneously operated. When desired, in place of the heating-coils, ice, a freezing- mixture, or other cooling-agents may be placed in the casing.

Title: Improvements in or relating to the Manufacture of Blue Sulphur Dyes.
Inventor: ELLIS GEORGE BELOE
Filed: 1903-06-08
Granted: 1904-03-31
Abstract: 12,879. Ellis, G. B., [Chemische Fabrik vorm. Sandoz]. June 8. Dyes, artificial. - Consists in making a blue sulphur dye by heating a mixture of p-oxy-p<1>- amido-m-methyldiphenylamine, described in Specification No. 58, A.D. 1902, aid sulphur, with or without a small quantity of chromium hydroxide, Cr2O3.H2O, with constant stirring to about 170‹- 200‹ C. The resulting blackish-violet mass may be powdered and used directly for dyeing. It is insoluble in water, but dissolves readily in the presence of alkaline sulphides to a blue colour in the cold, and to a brownish colouration on boiling, the vat dyeing unmordanted cotton at ordinary temperatures. The dye is a greyish-green, oxidizing on exposure to air to an intense indigo blue, which is fast to alkalies, washing, and light. A duller and more greenish shade is obtained by omitting chromium hydroxide. To isolate the pure dyestuff, a sodium-sulphide solution of the melt is oxidized by a current of air, precipitating the dye, or the leuco compound may be separated by a mineral acid, and, after washing and drying, freed from sulphur by extraction with carbon disulphide.

Patent GB-190323293-A (GB)
Title: Improvements in Prepayment Attachments for Gas Meters.
Inventor: FERSENHEIM RUDOLPH LEOPOLD
Filed: 1903-10-27
Granted: 1903-12-10
Abstract: 23,293. Fersenheim, R. L. Oct. 27. Gas meters.-The Figures show a plan and end and rear sectional elevations of the prepayment mechanism attached to a dry meter. The measured gas issues by a port for which a valve 56 on a sliding stem 59 is provided, and is led away from the valve-chamber 53 by a pipe 53<b>. The valve is accessible through a handhole closed by a screw plug with star head 55, which forms one of the bearings for the stem, the other being a socket 58. The valve is immediately operated by a lever 60, 61 turning with a crank 63 in a stuffing-box 57. A grooved shaft 22 bearing a worm 25 is geared through a change-wheel 37 on a radial arm 33, to the index mechanism of the meter, and the worm is engaged with a pinion 16 which, after prepayment, is turned on a shaft 12. Thus, the manual actuation shifts the worm as a rack, and the meter action screws it back again while the engaging pinion is stationary. With the worm moves an embracing-plate 26 prevented from turning by a guide-pin 28, and a cam-slot 67 in this plate makes the valve lever operate by acting on its crank 63. A rack 33 forming part of the cam-plate gears with a pinion 13 on the shaft 12 which ends in an index 78 showing the amount of gas paid for. The gearing with the index mechanism of the meter includes jointed shafting. The mechanism is mounted between a plate 5 which forms the back of a case 6, and a plate 8 on pillars 9. Actuating-mechanism ; coin action; coin-discharging mechanism.-The pinion 16 in gear with the worm is connected by a sleeve 14 to a starwheel 15 against which a lever 18 is pressed by a spring 20 both to hold it and make it jump when half turned. The coin, Fig. 4, is put into a slot 73 in a shaft 69 in a trough 83 and the shaft is turned by an external knob 91 so that the coin drives the star-wheel and then drops through a slot 103 in the trough. A pawl and ratchet 75, Fig. 3, prevent the reverse rotation of the knob. The sleeve and pinion have only a friction-tight connection, the hub 17 of the latter being split and sprung into the sleeve. Thus, if more coins are inserted than the number which corresponds to the extreme travel of the worm, the star-wheel will be turned without straining the worm and valve gear. Registers.-A pointer 77 on the sleeve and other pointers in gear with it show on counting-dials the number of coins paid. Casings; money boxes.-The casing 6 is attached to the valve-box 53 by set-screws 65, and is closed by a front plate combined therewith, below which is inserted the money box 99 which has an overlapping front. Fraud, preventing.-One of the set-screws locks the star head 55 of the plug which closes the valvebox, and the false bottom fits over a post 95 which recesses a seal 96. The money box is secured by a cross-bar 100 through staples 97, 98 and a padlock 102.

Leaf-turners.-In a leafturner for music and other books, the bottom rail a' of the bookstand is adjustable so that the upper edge of the book may be brought flush with the top of the stand. A top rail a<2> extends partly across the lefthand side of the back. An arm c is pivoted at the middle of the top of the back, and has fixed to it a pulley c' which is rotated by a Bowden wire e, the end of the wire being connected to a treadle. At the end of the arm c is pivoted a magnet. A small iron plate is fixed to the right-hand top corner of the right hand page of each opening of the book The arm normally stands on the right-hand side with the magnet just in front of the iron plates. When the treadle is operated, the arm swings over to the left, carrying the leaf with it. When the magnet reaches the top rail a<2>, it is tilted by the rail into a horizontal position, and is thus detached from the iron plate. When the treadle is released, the arm is brought back to its original position by a spring d, and the motion is so rapid that the magnet is clear away from the plate on the leaf which has just been turned over before it assumes its vertical position, so that the leaf is not turned back again.

Title: Improvements in Gearing for Fertilizer or Manure Distributors
Inventor: KEMP JOSEPH SARGENT
Filed: 1904-04-27
Granted: 1904-08-18
Abstract: 9679. Kemp, J. S. April 27. Manuring.-In manure and fertilizer distributers having wheeled bodies, beaters, and movable aprons or other feeding-devices operated by worm mechanism, the speed of which is regulated by moving a pinion into gear with concentric rims on a disc gear-wheel, means are provided for uncoupling the pinion from the worm spindle before moving it. The worm I is thrown out of gear with the wheel C by causing the spindle i to pivot about the stud g by means of the segment k<1> and rod k' connected to a lever. The pinion L is loose on the spindle i, and is moved into gear with a different rim on the face of a wheel mounted on the stud g by means of the rod o<1> connected to a hand-lever, which engages with a notched bar or segment. It is clutched to the shaft by means of a sleeve M moved by a rod p and a hand-lever. The two hand-levers are normally held apart by a spring, which thus tends to keep the clutch M in contact with the pinion L. When the pinion is to be moved, the clutch lever is pushed towards the pinion lever and the two then moved together, the pinion lever being afterwards locked in the notched bar and the clutch lever released.

Title: Improvements in and pertaining to Means for Distributing Actuating Fluid in Engines or Motors.
Filed: 1904-10-01
Granted: 1904-11-24
Abstract: 21,136. Clerke, Chapman & Co., and Woodeson, W. A. Oct. 1. Valves and valve gear.-Acombined fluid-actuated and mechanical gear for cylindrical oscillating valves for distributing steam, water, or other actuating fluid is shown in Fig. 1. The main valve B is operated by the lever F, the end of which engages a piston E. The ends of the piston E move in cylinders D', D<2> which communicate with the main steam pipe through passages N', T' and N<2>, T<2>. The piston E has also passages O<1>, O<2> for placing it in equilibrium at the ends of the stroke. Steam is distributed to the piston E by auxiliary rotary valves C', C<2> attached to the carrier G', which is free to oscillate about the spindle G, such oscil!ation being produced by the lever H through gear connected to the crosshead, or the lever may be actuated by an eccentric. Stop valves S', S<2> are attached to the exhaust openings Q<1>, Q' to vary the speed of the piston. Steam being admitted through one port L<1> to the main cylinder, the auxiliary valves C<1>, C<2> are moved until the passage T' is closed. The carrier then comes into contact with the lever F and moves the piston E into or nearly into the position shown. Steam then enters the cylinder D' and the ports L', L<2> are quickly opened to the exhaust pipe K and steam which enters at I. The opening O<2> then comes opposite the passage N<2>, putting the valve in equilibrium. The reverse action finally takes place. Should the piston E not be moved by steam, the movement of the valve is completed by the mechanical gear. Slide valves may be actuated by similar gear.
