Title: A New or Improved Variable Speed Gear.
Inventor: PLETTS JOHN ST VINCENT
Filed: 1904-01-19
Granted: 1904-02-25
Abstract: 1385. Pletts, J. St. V. Jan. 19. Motors, gearing for.-Change-speed gearing for electrically - driven machinery is arranged with a number of toothed speedwheels connected by eccentric toothed wheels which form paths for a pinion t o move from one speed to the next without being thrown out of gear. A driving-wheel a, Fig. 3, is loosely mounted on a shaft c, and gears with a wheel b feathered on to the shaft f. The shaft f is mounted in a frame h, and carries a pinion i which engages with one or other of the speedwheels j, l, n. The frame h is connected to the shaft c, and is free to oscillate and move sideways as the pinion i moves from one speed-wheel to another. The shaft c is moved by collars u forming a rack engaging with the long-toothed pinion v on the shaft r. The speed-wheels j, l, n are mounted on the driven shaft, and are connected by eccentric similarly-toothed wheels k, m which guide the pinion from one speed-wheel to the next. The speed is changed by causing the shaft r carrying two Geneva detents t to rotate through two quarter revolutions, by which means the pinion v is rotated and the shaft c moved as desired. The outer face of the wheel n, Fig. 8, is provided with complete eccentric guides 10, and also semicircular guides forming guide-paths p between the teeth q and recesses 5 for operating the detents t ; channels 7 are cut to allow the idle detents to turn, and plain spaces are left between the guidechannels to allow the detent a free path during running. The shaft r is shifted longitudinally to place the detents in their active position, and is automatically restored to its normal position. The shaft may be moved by a handle ; w, x show a detent. In one arrangement, an electric motor may be mounted direct on the shaft b. In a second arrangement, the frame h is made complete, and carries the rack u in the form of a sleeve on a fixed shaft c carrying the wheel a and attached to the motor. In another modification, two pinions i, one driving and one driven, are caused to run on opposite sides of the speed-wheels, each pinion being movable ; more than three speed-wheels may also be employed.

Title: Improvements in or relating to Exhaust Opening and like Machines used in the Preparation of Cotton and other Fibrous Materials.
Inventor: PILLING ANDREW
Filed: 1905-03-14
Granted: 1905-10-19
Abstract: 5279. Pilling, A. March 14. Feeding and conveying trunks. -Relates to trunks through which cotton &c. is drawn from the feeding-hopper to an exhaust opener or like machine. In order to facilitate the removal of dust and other impurities which accumulate in the grids, the latter are made reversible and are automatically rotated through two right-angles at suitable intervals. The grids b, Figs. 1 and 2, are attached to both sides of the door a, the edges of which are bolted to rails c carried at intervals by annular supports d which are enclosed in airtight casings and are capable of rotating on antifriction bowls e carried by adjustable supports e<1>. Means for automatically reversing the door carrying the grids are illustrated in Figs. 3 and 4. The door is connected by gearing v with a shaft l which is rotated through one revolu- ' tion intermittently each time the door is required to be operated. A weighted lever p normally rests on the plain part of a toothed sector i, which is turned through the space of one tooth each time a lap is completed by a movement of the lever h connected with the knocking-off mechanism of the hopper feeder. When the sector has been turned sufficiently, the lever p falls into the notch j<1> in the sector, and causes the upper plate t of a pair of guide-plates t, t<1> to depress a stud r, which is mounted to slide radially on a continuously-rotating worm-wheel n loose on the shaft l. This movement of the stud causes it to engage with a wiper s on the shaft l and to turn the shaft until the wiper w raises the weighted end of the lever p, when the sector is returned to its starting position by its own weight and the stud r by the lower of the two guide-plates t. To assist in rotating the grids, an auxiliary shaft may run under the length of the trunk and gear with teeth formed on the rotating supports d. Suitable means are provided for automatically shutting the air valve while the grids are being reversed, the valve being in two parts, the axles of which are connected together by segmental gearing so that they are opened and closed simultaneously.

Title: Improvements in Steam Traps.
Inventor: HARGREAVES FRANK
Filed: 1905-06-15
Granted: 1905-07-20
Abstract: 12,411. Hargreaves, F., and Hudson, J. G. June 15. Steam traps.-The outlet of a floating-bucket trap is controlled by a slide valve G which is actuated by the motion of an open-topped float B communicated to it by a rod C and a bell-crank lever E. In the position shown, the vessel B has been sunk by water from the casing overflowing into it, thus moving the slide valve so that a port Q communicates with a port H leading to the outlet passage J. The water in the vessel is blown out by the steam pressure through the pipe D into the chamber F, and then past the valve. The float is thus lightened, and rising to its highest position closes the outlet, at the same time putting the chamber A in communication with the chamber F by ports K, R, to permit of the escape of any air present. Other ports L in the casing communicating with the outlet passages are always covered by the slide valve. The vessel B may be shaped as shown, or an annular recess may be formed in the casing to ensure sufficient water remaining to raise the float after discharge. A grating is fitted to prevent the entrance and accumulation of solid matter.
