Patent GB-189809209-A (GB)
Title: Improved Stove.
Inventor: WINTER ROBERT
Filed: 1898-04-21
Granted: 1899-04-21
Abstract: 9209. Winter, R. April 21. Stoves; draught, regulating.-Relates to a stove fed with heated air and by direct draught on igniting, and later on by indirect draught. The air enters above the plate a and passes through the orifice b, Fig. 5, into the space i, and then through passages k, k<1>, Fig. 4, m, m<1> to the grate R, thereby being heated before combustion. An orifice h in the front wall of the stove may open into the space i to increase the volume of air. The orifices band h are provided with dampers e and g, both operated by the handle f, whereby the amount of air entering the stove may be regulated. When using direct draught, as on lighting, the products of combustion pass directly through an orifice o<0> to the smoke pipe o, while when using indirect draught the gases pass through apertures s<0>, s<01>, down side passages and through the bottom t and then up through passages z, z<1> and the chamber n to the smoke pipe o. A damper p operated by teeth on the damper e is arranged in front of the orifice o. When the damper e is arranged with its left-hand edge at 4, Fig. 5, the apertures o<0>, b, h are fully open, and the products of combustion pass directly to the smoke pipe. By closing the damper, the air supply and the consequent intensity of combustion are decreased and the direct passage to the smoke pipe is closed. A second aperture b<1> is also formed in the plate a, and, as soon as the damper e has roved past the position 2, this is uncovered and air enters into the space n, where it mixes with the products of combustion from the passages z, z<1> and passes with them to the smoke pipe. Slits q, q<1> in the grate R allow flames to enter the passage and complete the consumption of the fuel carried away in the combustion products. The passages r, r<1> serve for the heating of air which enters at the bottom of the passages. An arrangement of a pin and slot may replace the rack arrangement for the operation of the damper p. The combustion-regulating arrangements may be applied to a direct-draught stove by omitting the lateral passages in the casing, and the passages z, z<1>, and t, and replacing the full damper p by a perforated damper.

Title: Improvements in or relating to Water-meters.
Inventor: EISNER WILHELM
Filed: 1898-10-19
Granted: 1898-11-26
Abstract: 21,977. Eisner, W. Oct. 19. Liquid meters.- Relates to the type in which a large and small meter are coupled u p together, andconsists of a valve which will shut off one while the other is working. This valve f is cupshaped, and weighted as required at the upper part f*. It works in a cylinder e, and in the position s h o w n, w h e n the small meter is working, it passes the water, flowing in at g, through the ports f<1>, and e<1> to a chamber c whence it is discharged to the meter by a pipe h. With increased pressure, the valve rises, cutting off the small meter and opening communication with the large one by the ports f<2>, e<2>, chamber d, and pipe i. The meters work together, for a very short time only, while the valve is in an intermediate position, this being necessary to allow of the escape of water under the valve during its return. A modified form, in which the small meter is cut off before the other is brought into action and vice versÔ, is described. In this case, the escape takes place, but into the large meter chamber, through a series of small holes.
