Patent GB-189911548-A (GB)
Title: Improvements in Pumps.
Inventor: EDWARDS FREDERICK
Filed: 1899-06-02
Granted: 1900-09-01
Abstract: 11,548. Edwards, F. June 2. Air pumps.-Relates more especially to pumps of the kind described in Specifications No. 5175 A.D. 1894, and Nos. 9653 and 21,034, A.D. 1896. Instead of the usual snifting-valve, a device is provided for admitting air to the barrel during the discharge stroke only. Fig. 4 shows one form of the device. The admission of air to the barrel by the passage 1 is controlled by a slide valve 2 formed with a cylinder in which is fitted a piston valve 4. The ends of the cylinder are closed, but holes 12 allow some lost motion between the cylinder and pistons 4, so that, on the down-stroke corresponding with the suction stroke of the pump, the ports 8 are closed by the pistons 4 before coming over the ports 9, while on the up-stroke the ports 8 are opened, allowing air to pass through them from the ports 10. Three other valves for the same object are described. In one, the valve is opened bv the pressure of the water displaced by the bucket at the end of the suction stroke ; in the second, the valve is operated by a cam, and in the third by tappets. In order to minimize concussion and eddies in the discharge of the water, the pump is made as shown in Fig. 2. The central part 51 of the cover is conical, and the bucket is correspondingly recessed. The cover and barrel may also be chamfered adjacent to the outer part of the valves, as at 55, and the bucket chamfered as at 57. By these means the water is from the first directed radially outwards towards the valves, the bars forming the seats of which are, moreover, placed radially or nearly so to the pump axis, and of such a section as to offer a minimum of resistance to the flow of water parallel to, and through them. The cover, formed as described, may be arranged to lift, and so serve as a discharge valve.

Title: Improvements in Change and Reversing Gears.
Inventor: WILSON WALTER GORDON
Filed: 1900-09-14
Granted: 1901-09-14
Abstract: 16,386. Wilson, W. G. Sept. 14. Toothed gearing.-Relates to epicyclic toothed change gear or to change and reversing gear. Several modifications are described. In the form of gear shown in Fig. 1, there are fixed on the driving-shaft E a friction-wheel F and a pinion G, which gears with a series of planet pinions Q carried on studs on a disc or frame S keyed on the driven shaft T. There is also loose on the driving-shaft E a sleeve H, prevented from moving endways by the bearing L, and carrying a casing K composed of several portions as shown. This casing carries an internally-toothed ring P gearing with the pinions Q, and is internally coned and is pressed by the spring M, so as to tend to engage the friction wheel F. It is also provided with a friction ring F<1> capable of being engaged by a brake ring N, which can be assisted by a fixed brake ring 0 or by ratchet and pawl gear. When the casing is engaged by the wheel F, the whole of the gearing is locked, so that the driven shaft revolves at the same speed as the driver ; and when the casing is engaged by the brake ring N, the driven shaft rotates at a reduced or increased speed in the same direction, or at an increased, equal, or reduced speed in the opposite direction, according to the ratio of the gearing. In one modification, the internally - toothed wheel P is carried by the wheel F and the pinion G by the casing K ; and in another, the planet pinions are carried by the casing K and the pinion G by the driven shaft T. Three further modifications are produced by making the planet pinions Q each in the form of two pinions of different diameters placed side by side. Fig. 8 shows one of these three forms. The driving - shaft E carries the internally - toothed wheel P', and the driven shaft T carries a series of double planet pinions Q, Q<1>, which gear with the pinion G<1> fixed, in this case, on the casing.
