A<1>, B<1> and A', B' are admission and delivery ports, respectively. Brackets G, g fixed to the pump side carry guide-ways G<1>, and have outwardly-extending ends G<2>, supporting the levers I, i on pivots G<3>, and also forming bearings for the cams N, N'. Figs. 3 and 4 show this actuating-mechanism in detail. The reciprocating rod J, which receives its motion through the rod P from the pumping- engine, carries four nuts, J', J', J<3>, and J<4>, by which the position of the cams is adjusted. The valves are connected by the rods H, h, through the resilient part shown, to the levers I, i. The reciprocating cams impart positive and regular movement to these levers, but in the case of their being a greater resistance to the motion of the valve than the amount determined by the springs, the valves remain stationary, and act quickly when this resistance falls below their pressure.

Title: Improvements in Straining Apparatus suitable for Straining Paper Pulp.
Inventor: BUSBRIDGE FREDERICK GEORGE
Filed: 1903-11-17
Granted: 1904-05-12
Abstract: 25,075. Busbridge, F. G. Nov. 17. Strainers. - The strainer c, the walls and bottom of which are constructed with suitably-formed slits, is given a vertical reciprocating motion by the eccentrics e on the rotating shaft d. The drawing-off pipe o, which has a flexible part p, is extended upwards, and is surrounded by a tubular p i p e or division q, so that liquid material from the vat b falls over the top of the pipe o when the strainer c descends, and flows back to the vat when the strainer ascends, the slits or openings in the strainer being thus prevented from clogging. Air inlets r effectually prevent any partial vacuum. Holes t may be employed to clear out completely the pipe q. In a modification, the pipe o is introduced at the top and extends nearly to the bottom of the strainer. It is surrounded by a second tubular division extending from the bottom nearly to the top of the strainer.

Title: Improvements in and relating to Domestic Fire Grates and Cooking Ranges.
Inventor: PARKER JOHN
Filed: 1903-12-31
Granted: 1904-12-22
Abstract: 28,713. Parker, J. Dec. 31. Grates; flues; dampers.-In domestic firegrates and cooking-ranges of the kind described in Specification No. 1721, A.D. 1902, the bottom of the grate is perforated with tapered holes to heat the air supply and to allow dust to fall to the ashpan, and the oven or boiler flues are formed by means of bricks with tapered grooves. The waste gases are used for heating a chamber beneath the ashpan, and a damper, having an adjustable pivoted blade or arrangement of blades, is employed to check the draught in the chimney or flues. The perforated bottom A, Figs. 1 and 2, of the grate may be of firebrick, asbestos, metal, or like material, shaped preferably as shown, and rests on legs or brackets which may be grooved to support a removable ashpan B. The block may be formed with ridges between the perforations, and it may consist of pieces held in a frame. A firebrick or plate A<1> with tapered grooves a<1> is applied to form an oven or boiler flue. A chamber C beneath the ashpan is heated by gases which pass from the grate through the brickwork at D into a chamber constructed between the chamber C and oven C' and provided with baffles E.

Patent GB-190410997-A (GB)
Title: Improvements in Automatic Draught Regulating Apparatus for Steam-boiler and other Furnaces
Inventor: SCHICK LEOPOLD
Filed: 1904-05-12
Granted: 1904-07-14
Abstract: 10,997. Schick, L., and Schaffer, A. May 12. Air supply, regulating. - A chimney damper or register is connected with and operated by a rod having two pistons working in a steam and a liquid cylinder, so that, on opening the first fire-door, the damper falls and closes the chimney flue, while, on closing the last door, the damper is raised to its full height,and afterwards gradually falls. Thus on opening the door 1, Fig. 2, the eccentric 2 pushes a stud 3 on the rod 4 and thereby pulls the wire rope s, which, as shown in Fig. 1, opens a valve q and pulls back the pawl v which normally prevents the damper from falling by coming against the stop collar u on the piston rod. Thus the damper h falls, lifting the pistons, and the liquid flows through the channel p. On opening the last door 6, Fig. 2, the eccentric 7 pushes the rod 9 back so that the hook 10 on it catches the nose of a pawl 12 linked through a rod to a wire rope c, joined to a sliding valve b. On closing this door, the eccentric forces the rod 9 to the left by striking the stop 14 on it, thus pulling the wire rope c and raising the valve b. Steam is thus admitted through the port i, and forces the piston d to its lowest position, whereby the damper is lifted. But, in falling, a stop k on the piston rod forces the lever land valve b down, so that the steam may escape by the exhaust port j, the rope c being released by the pin 16 striking the pawl 12. The damper can now fall, but only slowly, as the liquid above the lower piston n can only pass through the opening regulating by the valve r ; when the collar a strikes the pawl v, which is held against the rod by a spring, the damper comes to rest. When only one door 6 is used, the rod 9 is connected to the rope s. In the modification shown in Fig. 6, the rods 22, 23 are connected, by a double lever, to the rod 4, Fig. 2, so that, on opening the first door, the rod 23 is turned and turns a drum, winding up the ropes s, w and thus opening the valve q and drawing the pawl v back. The spring pawl 25 is also drawn back over one tooth of the ratchet-wheel. 20, which is provided alternately with long and short teeth. Or closing the first door, the pawl 25 pushes the wheel one tooth on, releasing the ropes s, w. On opening and closing the last door, a long tooth on the wheel releases the belt crank lever 19, and the weight 18 opens the valve b. Steam enters above the upper piston and forces it down, raising the damper and closing the valve b. The steam cools gradually, and the condensed water and steam pass through the passage 26 and pipe 27, allowing the damper to fall slowly.

Whistle signals.-Relates to means for operating a whistle in connection with air brakes or other mechanism, the invention being described as applicable particularly to a motor car or locomotive for operating with one hand the air-brake valve and the valve of the pneumatic track-sanders. The valve b controlling the air brakes is fitted with a removable handle k, the hub of which is provided with a notched cap m engaging the shank of the handle k and being secured in position by a screw n ; or the cap may be screwed on the valve spindle. A lever p, for operating the valve f controlling the track-sanders or the whistle, is mounted in lugs o on the cap m, and is bent, as shown, so that it may be grasped by the hand when manipulating the handle k. The front end of the lever is fitted with an arc-shaped rim r sliding immediately under the spindle of the valve f, which is of the self-closing type, one end of the rim r being formed with an incline to operate the valve f in cases of emergency, when the handle is turned. The lever p may, however, be depressed, and the valve f operated separately. In a modification, shown in Fig. 7, the handle k works in a slot y in the valve casing b, a rectangular part w preventing the turning of the handle. The lever p with its arc-shaped rim r is mounted in lugs o on the handle, to which a stop v is fitted, as shown.

Granted: 1905-05-25
Abstract: 3083. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Feb. 14. Dyes, artificial.-Blue to violet-blue sulphuretted dyes, which are difficultly soluble in cold and readily soluble in hot solutions of sodium sulphide to form colourless solutions, and are practically insoluble in caustic soda, are obtained by heating with sulphur an alkali salt of a p-amido-p-oxydiarylamine, such as p-amidop-oxydiphenylamine, its arylated derivatives, and the homologues and substitution products of these compounds. In examples, p-phenylamido-p<1>-oxydiphenylamine, p-amido-p<1>-oxy-m<1>-m<1>-dichlordiphenylamine, and p-xylylamid p-oxydiphenylamine are heated with caustic alkali solution until free from water, sulphur is added, and the temperature is raised. The melts are dissolved in hot sodium sulphide solution containing caustic soda. The dyes are precipitated by blowing air through the solutions. The dye derived from phenylamidooxydiphenylamine is a powder having a metallic lustre. It is almost insoluble in cold aniline, but dissolves slightly in hot aniline to a blue solution. With sulphuric acid it gives a blue solution. Hot sodium sulphide solutions of the leuco compounds become fixed on vegetable fibres. On being exposed to the air, the dyeings become blue to violet-blue.
