Title: Improved Means for Operating Suction Valves in Reciprocating Pumps.
Inventor: MUNRO HUGH
IPC: F04B53/10
Filed: 1910-05-06
Granted: 1911-03-02
Abstract: 11,217. Munro, H. May 6. Concussion - preventing devices; valve-gear; regulating delivery by by-passes.-The invention relates to improvements in reciprocating pumps of the type in which the suction valve is positively returned to its seat by means of fluid pressure from the delivery, while at the same time a small quantity of the pressure fluid from the delivery is admitted to the suction side of the cylinder for cushioning purposes. The suction valve A<1>, Fig. 2, is formed with a trunk piston B working in a cylinder B' which is connected by the pipes C, D, Fig. 1, to the pump delivery. Connecting the pipes C, D is the casing C<1> containing a mushroom valve, the projecting stem C<2> of which is adapted to be engaged by a lever C<3> operated at nearly the end of the suction stroke by a tappet C<4> on the connecting-rod C<5>. When this occurs, the pressure fluid is admitted to the cylinder B', and the suction valve is forced upon its seat; at the same time ports B<2> in the piston B allow some of the fluid to pass to the suction side of the pump. The pipe C may be prolonged into the trunk piston so as to form a jet and increase the effect on the piston of the entering fluid. By adjusting the position of the fulcrum rod E, the time at which the mushroom valve in the casing C' is actuated may be altered, thus varying the time of closing of the suction valve and the effective stroke of the pump. A form of the invention applicable to three-throw pumps is described in which a rotary disk valve driven through an adjustable clutch from the main shaft takes the place of the mushroom valve in the casing C<1>.

Title: Improvements in the Separation of the Constituents of Gaseous Mixtures.
Inventor: HEWITT JOHN THEODORE
IPC: B01D53/14
Filed: 1910-05-21
Granted: 1911-05-22
Abstract: 12,424. Hewitt, J. T. May 21. Gases, separating mixtures of.- To recover the work used in separating the constituents of a gaseous mixture, the solvent is contained in a series of saturation vessels connected to apparatus for receiving the undissolved gas, the solvent, and the gases which expand from the solvent, these apparatus being connected together in such a way that the work done by the expanding gases supplies the energy necessary to force the undissolved gas into the saturation vessel the next higher in the series, the gas which expands from the liquid into the next lower saturation vessel, and the solvent into its saturation vessel. The apparatus is particularly suitable for separating the constituents of air, water being used as the solvent. The saturation vessels 1, 2, 3 are connected by suitable valve gear to piston pumps a, b, c, which are all connected to a common shaft driven by a suitable motor and to which is coupled a gas-compressor. In operation, gas is forced through the pipe g into the solvent under pressure in the saturation vessel 2, and it is preferred to provide devices for distributing the gas in the liquid and for preventing splashing at the surface of the liquid; or the liquid may pass over coke or like materials in vessels containing the gas. Some of the solvent is forced into the pump c<2> by opening the valve f<2>, and this valve closes when the pump is half filled. The gas expands from the solvent and drives the piston, and on the return stroke, the valve e<2> is opened so that the gas is forced into the pump b<2>. When all the gas has been driven out of the pump e<2>, the valve e<2> is shut and the valve f<2> opened so that the solvent is returned to the top of the saturation vessel 2. The gas in the pump b<2> is forced into the saturation vessel I through a non-return valve. Undissolved gas at the top of the saturation vessel 2 is allowed to expand into the pump a<3> by opening the valve d<3>, and is forced on the return stroke of the piston into the saturation vessel 3 through a non-return valve. The operation of the pump connected to the other saturation vessels is the same, and the two streams of gas passing in opposite directions become enriched with the constituents of the mixture.

Abstract: 17,323. Bache, E. W. July 29. Ink-ribbon mechanism. - (1) Automatic reversal. Relates to mechanism of the kind in which a feed-shaft 13 is movable endways to bring either of the gears 16 into mesh with gears 17 on the spools 18, the position of the feedshaft being controlled by the engagement cf worms 29 on the feed-shaft with arms 26 which are set by obstructions on the ribbon 27. The feed-shaft is driven through gears 12,11, 10 from a countershaft 6, which is driven from the spring drum 1 by a pawl 2 and gears 4, 5. The wide intermediate pinion 11 is adjustably mounted in a slotted bracket 14 to permit adjustment of the shaft 6, 13. The arms 26 are formed on bell-crank levers which are connected by links 24 to pivoted feelers 19, the arms being normally held clear of the worms 29 by the engagement of fingers 21 on a spring-tensioned shaft 22 with the inner ends of the feelers. The obstructions for operating the feelers consist of metal loops or catches secured to the ribbon or the attachment tape. When the ribbon is fed off one spool, the obstruction engages its feeler and turns the arm into engagement with the worm, whereby the feed-shaft is moved endways to reverse the feed. During the initial part of the reversed feed, the obstruction is carried back clear of the feeler and allows the feeler and the arm to resume the normal position. The feed-shaft is held in the set position by means of an arm 30, which is secured to the rock-shaft 22, and is adapted to engage grooved collars 31, 32 on the feed-shaft. (2) Feed.

In the form shown in Fig. 1, the driving-shaft B carries a cam D, which may be fixed to or slide on a feather on the shaft and has no projecting abutments; on this cam turns loosely an oscillating wheel E with teeth E<1>, E<2> engaging teeth F<1>, H<1> on a fixed oil - retaining casing F and a wheel H on the driven shaft C, respectively. The boss E<5> of the wheel E is formed spherical to engage similar cups in the wheel H and casing F. Fig. 2 shows a form in which, for driving a winding-drum or winch barrel M, the wheel E has duplicate sets of teeth engaging duplicate sets on the fixed parts F and the driven drum, so as to balance the thrusts of the engaging parts. Fig. 3 shows a modification adapted to be employed as a variable-speed gear. The wheel E has five sets of teeth gearing with wheels H, P carrying pulleys P<5>, H<5>, with wheels J, K carrying brake-drums J<3>, K<3>, and with a casing F carrying a pulley F" and a brake-drum F<3>. Any of the brakedrums may be held, and the power taken from any of the pulleys. The boss of the wheel E is formed spherical, as in Fig. 1. The Specification as open to inspection under Section 91 (3) (a) comprises also the following matter. The invention is applicable to gears for high-speed motors, presses, drawing-benches, steering-gears, &c. The teeth on the wheels may be dispensed with. By reversing the action the gear may be used as a multiplying-gear. A variable-speed gear similar to that shown in Fig. 3 is described, only one driven wheel being provided, but the braked wheels being also provided with means for transmitting power. In the form shown in Fig. 3, the wheels J, K may be provided with means for transmitting power. The action of the device is more fully described with the aid of diagrams. This subject-matter does not appear in the Specification as accepted.
