Title: Improvements in Automatic-feed Weighing Machines
Inventor: RICHARDSON HENRY
Filed: 1902-02-21
Granted: 1903-03-12
Abstract: 4414. Richardson, H. Feb. 21. Automatic-feed weighers.-Relates to weighing- apparatus of the kind described in Specifications Nos. 1890A and 6345, A.D. 1891, and No. 18,690, A.D. 1894. The beam 16, Figs. 2 and 3, carries weights 18 at one end, and a receptacle 17 at the other end, the receptacle being underneath the vertical walled mouth 21 of the feed-hopper 20. The hopper has an inclined grid 58 to divert lumps into an accessible chamber 61, and the vertical walls of the mouth of the hopper prevent jamming when pulverulent materials are being weighed. In the fully-open position, as shown in Fig. 3, the main shutter 22, which is pivoted at 23, is held open by toggle-levers 29 supported by a bar 35 resting on a three-armed catch device 37<b> pivoted at 37. A spring-pressed stop 26 on a bar pivoted at 28 to the shutter rests on a projection 27 on the receptacle, and when the beam tilts, the stud 33 on the shutter falls to the lower end of the slot 34 and the shutter swings into the trickling-feed position. When an equipoise is obtained, a projection on the beam strikes the three-armed lever, which frees the toggle-levers and a catch 43 holding up the trickling -feed shutter 25, so that this shutter falls and cuts off the supply. An adjustable plate may be fitted to the mouth of the feed-hopper. A weighted bar 53 is pivoted to the frame, and is adapted to rest on a peg 40 on the beam, to compensate for the material in the air at the time of cut-off. The bar is removed from action by a rod 56 connected to the shutter. A bearing for the levers &c. consists of a grooved pin 64, Fig. 10, and a grooved lever 63 is secured on the pin by a wire 67 in the grooves acting as a key. A modified shutter arrangement has both shutters mounted on the same pivots and working in the same directions.

Title: Improvements appertaining to Condensing Apparatus for use in the Manufacture of Gas.
Inventor: CLAPHAM SAMUEL BANNISTER
Filed: 1902-07-28
Granted: 1903-06-11
Abstract: 16,668. Clapham, S. B. July 28. Condensers.-The accumulation of naphthalene and other deposits is prevented by arranging a series of towers so that all of the several parts or sections may in turn be subjected to all the varied conditions of the process, with the result that the deposits which at one time are left in one part of the apparatus by the cooled gas are subsequently re-dissolved or assimilated by the hot gas. In the four-tower apparatus shown in Figs. 1 and 2, in which, in consequence of the gas supply entering at the top, and the water supply at the bottom, of each of the towers 1, 2, 3, 4, the gas in its hottest condition at all times meets the water when also at its highest temperature, and the temperatures of both gas and water gradually diminish from the place at which the gas enters to that at which it escapes, coupled ordinary or rotary multiple valves are so arranged in the gas and water pipes that, when the gas enters the tower 1, and passes through the towers 2, 3 to the tower 4, the water enters at the tower 4, and traverses the towers in the reverse direction to the tower 1. By altering the valves, the gas may be caused to traverse the towers in the order 4, 1, 2, 3, and the water in the order 3, 2, 1, 4. Similarly, the other towers may be made the initial and final towers in the series, and any one of the towers may be thrown out of use for repairs &c. by means of valves placed between the gas outlets of the towers and the gas inlets of the next towers of the series. By opening the central bye-pass valve x and closing all the other valves, the gas may be caused to pass direct from the main inlet pipe f to the main outlet pipe h, without entering any of the towers.

Patent GB-190418174-A (GB)
Title: Improvements in Speed Changing Mechanism
Filed: 1904-08-22
Granted: 1905-08-22
Abstract: 18,174. British Thomson-Houston Co., [General Electric Co.]. Aug. 22. Motors, gearing for.-Relates to variable-speed and reversing toothed and belt gearing applicable to electric hoists and to other machinery in which it is desired to let the driving-part rotate continually at a high speed. The field-magnet frame 6, Fig. 2, of an induction motor is secured to a sleeve 5 rotatable upon a shaft 4, which carries the armature 7 and is journalled in pillow blocks 2, 3. The sleeve 5, besides supporting collecting-rings 10 in contact with insulated brushes 9, carries a toothed wheel 25 in mesh with a wheel 24 secured to a countershaft 11. The relative movements of the parts 6, 7 are determined by the relative movements of the shafts 4, 11, which are therefore connected through expanding belt pulleys consisting of alternate parts 14, 14<1>, Figs. 2 and 3, movable simultaneously in the same direction but in opposite senses relatively to fixed parts 13, 13<1> respectively. These parts have conical faces consisting of ribs 15, Fig. 4, alternating with shots 16 so that they may interlock in pairs to form V-shaped grooves of variable diameter. The parts 14, 14<1> are operated simultaneously by means of non-rotating screws 17 of long pitch that may be reciprocated inside the shafts 4, 11 respectively through the agency of a crosshead 22, screw 22<1>, and nut 22<2>, and handle 22<3>. This motion of each screw 17 effects the back and forward revolution of a long nut 18, Fig. 3, which is kept from moving longitudinally by a flange 18<1> retained against the end of the shaft by a union 19. The outside of each nut 18 is cut with a screw-thread of short pitch, which causes the longitudinal movement of a segment nut 20 projecting through a slot 21 in the shaft from one of the parts 14, 14<1> to which it is secured. To the opposite end of the sleeve 5 is secured a toothed wheel 26, Figs. 2 and 5, which meshes with two long pinions 27 carried by a yoke 28 rotatably mounted on the shaft 4. Other pinions 29, carried by the yoke 28, mesh with the pinions 27 and with a smaller wheel 30 secured to the shaft 4, and a pinion 31, concentric with the shaft 4 and secured to the yoke, meshes with a wheel 32 mounted on the driven shaft 33 carrying, for example, a hoisting-drum 34. If the ratio of the diameters of the wheels 30, 26 be equal to that of the wheels 24, 25, no motion will be communicated to the yoke 28 and drum 34 when the diameters of the expanding pulleys are equal. At other times the yoke revolves with whichever of the wheels 26, 30 has the greater peripheral speed. Since the travel of the yoke is measured on the more slowly moving periphery, and since the wheels differ in diameter, the angular speed of the yoke is greater in one direction than in the other for the same ratio of the diameters of the expanding pulleys, a feature of special importance in hoisting.
