Patent GB-189702087-A (GB)
Inventor: CLARK MELVILLE
Filed: 1897-01-26
Granted: 1897-05-22
Abstract: 2087. Clark, M. Jan. 26. Organs.-Relates to American organs. Blocks C, attached to the wind-chest or vacuum chamber B, contain the reed-chambers C<1>. These chambers are covered by valves C<4> which may be raised by a tape E<2> attached to each of the valves in a vertical series, and actuated by a pneumatic motor E, E'. All the passages C<10>, which contain reeds of the same set, are controlled within the wind-chest proper by a single mute D', D<2>, etc.; these mutes have cranks outside the walls of the vacuum chamber which are connected by links D<3> to the stops which may be operated at the organ front. The pneumatic motors E are fixed on the under side of a supplementary wind-chest B<1>, which is in communication with the chamber B. The portions E and E<1> are connected by a broad flat duct e<1>, shown in Fig. 8, which is a section on the line 8-8. Through a cross-port b<11> a valve stem f extends, carrying two valves F<1> and F<2>. When the stem f is in its lowest position, the motor E is open to the atmosphere and therefore becomes distended, but, when the stem f is in its highest position, the motor E is in connection with the chamber B, in which the pressure is lower than that of the atmosphere and therefore the motor E, E<1> collapses, drawing up the tape E<2> and opening the valves C<4>. When the motor again distends the valves fall back, partly by their own weight and partly by the action of the spring C<5>. The valves F<1> and F<2> are actuated in one of two ways. The first method is by means of the corresponding manual key H, fulcrumed at h, and which, on being depressed, raises the rod H<1> and hence the lever G, which in turn communicates its motion to the valve F<1> through the spring F<3>. The second method is by means of the perforated strip J, operating over the tracker-board J<1>, the ducts of which are connected by a flexible tube J<2> to corresponding ducts J<3> opening into auxiliary pneumatics K. When a perforation of the music strip passes over a duct J<1>, the pneumatic K is in communication with the outer atmosphere and therefore distends, thereby raising the lever K<1> and with it the valve F<2>, The springs K<3> and P bring the levers K<1> and G, respectively, back into their lowest position after having been raised. Swell louvres R, R' are situated on both sides of the instrument.

Title: Apparatus for Measuring the Velocity of Air and other Gas Currents.
Inventor: KUEHNE HERMANN
Filed: 1897-12-15
Granted: 1898-11-19
Abstract: 29,763. K³hne, H. Dec. 15. Anemometers.-The instrument is for indicating the draught in furnaces, chimneys, &c. A graduated glass tube A is open at one end to the atmosphere and at the other is fixed to a cap H from which a bent pipe L passes into the flue. A light cylinder E slides closely in the tube and is supported by a fine spring F. The variations of draught are indicated by the position of the cylinder on the scale. The instrument may be modified for force draughts and for comparing two currents in separate flues. Further, where the draught is subject to great variation, the spring must be made adjustable. A method of doing this is shown in Fig. 3. The hooked arms O on a screw G gather up or release as many coils of the spring as may be required to give the necessary strength. The screw cap V allows of adjusting the cylinder to the zero of the scale.
