Title: An Improved Duplex Driving Gear for Bicycles and other Cycles, and for other purposes.
Inventor: THOMPSON WILLIAM JAMES
Filed: 1898-01-11
Granted: 1898-04-16
Abstract: 726. Thompson, W. J. Jan. 11. Toothed gearing for bicycles and other cycles and for other purposes whereby a two-speed gearing is obtained. The disc B secured at A<1>, A<2> to the crank A carries pins B' for the toothed pinions C, each of which gears with the toothed wheel D running on ball bearings D<1> and also with the internal teeth of the chain-wheel E. A locking- plate F has slot guides F<1> on pins B<2> on the disc B, and bears against a spring F<4> adapted to maintain the sector F<3> attached to the plate in gear with the wheel D, and the key piece F<5> in engagement with the slot d<2>, and so cause the motion of the crank A to be transmitted to the chain-wheel rim without multiplication. A locking-pin G is carried by bands or clips G<2>, and has a spring G<1> suitably controlled, adapted to press it against the driving-gear. When the control is released, the pin G is forced against the dust case H, which has an opening through which protrudes a flange F' of the locking-plate F. The pin G catches on the inside of the piece F', and forces it outwards and thus moves the plate into the position shown by dotted lines in Fig. 2. This releases the wheel D from the sector F<3> and the key F<5>, and as the wheel D revolves the pin G engages with the socket and thus prevents further revolution of the wheel D. By this means the revolutions of the crank are multiplied upon transmission to the chain-wheel E. To change from high to low gear the pin G is withdrawn. The operating-connections consist of a draw piece J<1>, bell-crank levers J<2>, J<4>, chains, cords, or rods J<3>, J<5>, and a hand-lever J.

Abstract: 12,565. Brewster, F. W. June 4. Golf; nets and screens.-Relates to practice apparatus for play within or out of doors. The apparatus consists essentially of an enclosure of net-work with a top covering, such as shown in side elevation in Fig. 1, within which the player stands and practises the various strokes, the balls being automatically returned by inclines and the like. The network back a, a<2> may be doubled in such a way that balls driven for scoring purposes through openings in the front net may be stopped by the second net, which may be hung on a roller a<3>. The balls fall into a trough a', from which they roll to the sides and back to the player. For returning the balls the inclined flexible catcher or retaining-device d with side channels is employed. A screen e prevents the passage of badly-bit balls under and beyond the back a. In the scoring- apertures in the back breakable or sounding indicative objects may be placed. If desired, tapering tunnels with inclined bases may be placed behind the nets into which the balls may be driven. All the parts of the apparatus are suitably protected to prevent damage to the balls. Ordinary netting or coco-nut fibre may be used. The frame may be made conveniently of iron barrelling united by T-pieces, while suitable means are provided for stretching the nets &c. In a modification, the incline d may be made continuous with the back net.

Title: Improvements in Apparatus for Preventing Collisions at Sea.
Inventor: GHERASSIMOFF NICOLAS
Filed: 1899-01-10
Granted: 1899-12-09
Abstract: 594. GhÚrassimoff, N. Jan. 10. Signals, ship.-Relates to apparatus for indicating on board ship the proximity of land, other vessels, icebergs, and the like. The vessel is preceded by three small, submerged, electricallypropelled pilots 1, 2, 3, Fig. 1. They are arranged on the circumference of a circle the diameter and distance of which from the vessel depend on her speed and manoeuvring power. Power is supplied to them through cables, through which also signals can be conveyed to the vessel. The middle one 2, Fig. 3, is mounted on vertical trunnions in a frame b to which the cable Z is attached. It is provided with a large rudder G to steady it. It can, however, be locked to the frame to turn with it. The side pilots or feelers are directed outwards and maintained in position by rudders and by the lines c, c<1> connecting them to the central one. The whole system can be manoeuvred by reducing the current to one or other of these side pilots. Should a vessel strike one of the connecting-lines, the side pilot affected rings a bell on board the ship so that her course can be altered to prevent a collision. A buoy u is attached to each pilot by a pole K, Fig. 3, the poles being connected by lines M. Floating obstructions are thus detected. Shoals are discovered by hanging levers connected by lines M<1> which, when deflected, complete an alarm circuit. Should the central pilot strike an obstruction, a buffer i completes the alarm circuit. The side pilots have coloured lights to give information to an approaching vessel.
