Title: Improvements in or relating to Weeding Tools applicable also to other Horticultural Purposes
Inventor: POTT REGINALD HENRY
Filed: 1904-08-03
Granted: 1905-06-29
Abstract: 17,034. Pott, R. H. Aug. 3. Weeds, destroying; planting-tools for garden use. -A tool for horticultural and similar purposes, such as weeding and transplanting, is constructed with fork-like jaws, so as to withdraw the weed or plant without disturbing the ground unnecessarily. The two parts A, A', Fig. 1, are hinged together at B and fit into tubular shanks D. Two prongs C' are connected to the part A, and three prongs C to the part A, the prongs C<1> being opposite to the spaces between the prongs C. The prongs are all flattened and pointed at the ends C', the flat parts being preferably roughened or grooved. The outside edges of the outer teeth C are provided with ears C<3>. The tubular shanks D may be long or short, but are preferably of such a length that the tool may be used without excessive stooping. The prongs are preferably of the crosssection shown in Fig. 3. The tool cannot open or close beyond certain limits, and may be fitted with a hinged step G for the operator's foot. The parts A, A<1> may be normally held apart by a spring, and the number of parts A, A' and prongs C, C' may be varied. The tool may be curved to surround the weeds, and the prongs may be parallel or tapered. Fig. 4 shows an implement for cleaning the prongs. The V-shaped notch J corresponds in shape to the prongs and other scraping- edges J' are provided. A spanner or key J<2> formed near the centre of the implement allows the nut B of the pivot of the weeding-tool to be tightened. According to the Provisional Specification, curved metal pieces with sharpened edges may be used instead of the prongs.
Patent GB-190417416-A (GB)
Title: Improvements in combined Driving, Free Wheel and Brake Mechanism for Velocipedes.
Filed: 1904-08-10
Granted: 1905-07-13
Abstract: 17,416. Rudge-Whitworth, Ltd., and Pugh, J. V. Aug. 10. Brakes ; driving-mechanism.-In the type of driving, free - wheel, and back - pedalling brake mechanism in which a nut or the like moves upon a screwed boss on, or attached to, the chain-wheel, the threads of the nut are made larger than those of the boss, so that the nut always lags behind, and consequently travels endwise along, the boss until the nut engages the brake or brake-operating device, or with the hub, according to the direction of rotation of the chain-wheel. In the form shown in Fig. 1, on commencing to drive, a doubleconed nut g, lagging behind the threaded boss h<2> of the sprocket-wheel h, is drawn into contact with the ball cone a<3>, when, its rotation being arrested, the nut is consequently drawn tightly into the cone and thus transmits the rotation to the hub. On back-pedalling, the nut again lags and now travels inwards until it engages a non- rotatable part c<2>, which the nut then quickly forces inwards to apply the Weston-clutch type of brake e, e<2>. The parts a<1>, a<2>, c, c<2>, e, e<2> are suitably ribbed, the notched sleeve d being ensured against rotation by engagement with a correspondinglynotched piece l on the chain stay of the bicycle. A number of modifications are described. On back-pedalling, the loosely-fitting nut may engage a rotatable ring having teeth adapted to engage similar teeth upon the end-plate of the Weston clutch, the ring and end-plate being connected by an involute spring ; or the nut may urge a wedge ring between the two parts of a non-rotatable hollow drum thereby expanded into contact with the hub ; or, as shown in Fig. 36, the nut g may have one end conical both internally and externally, so that, on back-pedalling, it engages a sleeve u recessed to receive an arm of a laminated lever v which expands a band w into engagement with a flange a<4> of the hub; or a band may be drawn tightly around the hub. In other arrangements, a screwed sleeve with teeth on its inner end is adapted to engage with teeth upon a non-rotatable conical brake drum and then to force the drum quickly into contact with the hub, or, as shown in Fig. 47, the drum y may be screwed to the sleeve g, so that, in driving, it rotates with the hub, but, on backpedalling. its rotary motion is arrested by a notched plate or by a plane or fluted cone d. The parts y, 1, and z are ribbed to prevent independent rotation but to allow of independent lateral motion. The spring n is in considerable initial compression. If desired, the rotation of the sleeve g may be arrested by engagement on its inner face with a tubular piece secured against rotation by ribs on a fixed part, or, on back-pedalling, the sleeve may engage an externally-threaded, rotatable sleeve on which a non-rotatable brake drum works.

Title: Improvements in and relating to Winches or Hoists for Coke Oven Doors and the like.
Inventor: KUHN RUDOLF
Filed: 1904-08-17
Granted: 1904-10-20
Abstract: 17,883. Kuhn, R. Aug. 17. Coking.-A winch for raising the doors of coke ovens travels along rails situated above the doors, and is pushed from the floor level by means of a depending bar. A shaft t is driven by means of an endless chain i passing around a guidepulley z<1> and a wheel z on a shaft w, and carries winding- drums for the chains m, y. The latter passes over a pulley x on the shaft w and carries a counterweightf. The door c is held in the raised position by catching the chain i on a hook l. While the winch is being moved, the hook is drawn up out of the way by means of a sliding bar o with a pulley n and chain p. By pulling down the latter and catching the ring r on a peg s, the chain m is pulled aside as indicated. The operations are thus performed at some distance from the oven.

Title: Improvements in Steam Engine Air Pumps.
Inventor: WEIR WILLIAM
Filed: 1904-11-02
Granted: 1905-11-02
Abstract: 23,659. Weir, W. Nov. 2. Pumping-engines; valve gear.-Relates to single, vertical, direct-acting air pumps driven by steam cylinders fitted with any type of steam-distributing valve, and consists mainly in means for overcoming defects due to the unequal and unbalanced loads on the pump piston upon its upward and downward strokes. Below the main steam cylinder A is arranged a smaller open-ended auxiliary cylinder A' fitted with a plunger which is attached to the main piston C ; the annular space a<1> thus formed communicates by a pipe F with the steam-inlet pipe, and always contains steam at initial pressure. Unequal steam-pressure areas on the upward and downward strokes respectively are thus provided, and these are suitably proportioned to the different loads on the pump piston. In order to decrease the height of the pump and secure compactness, the auxiliary cylinder A<1> is supported directly by the pump cover H, a closed chamber h thus being formed above the discharge valves of the pump. By this construction for an air pump working in connection with surface condensers, any steam leakage is absorbed by water fed by the pump to the boilers, there being therefore no heat loss. The tappetactuated valve E, which may be the auxiliary valve of any well-known type of valve gear, is operated from the pump bucket by means of a rod K working on a guide L<1> and actuating the valve spindle through a crosshead M and swivelconnection O.

Title: Improvements in and relating to Dynamo-electric Generators.
Filed: 1904-12-02
Granted: 1905-06-15
Abstract: 26,293. Allgemeine Elektricitõts-Ges. Dec. 3, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Dynamos, regulating field magnets.-In a trainlighting &c. system, in which the armature A of the generator is driven from a car axle and is connected in parallel with a storage battery B through an aluminium cell C or an automatic reverse-current cut-out, in order to prevent injury to the aluminium cell &c. when the armature current is reversed by the double-pole switch u on the reversal of the train, the field winding of the dynamo is divided into two parts, one of which F<1> is excited from the battery and the other F<2> by the armature current. With the switch u in the position shown, both coils F<1>, F<2> have the same action, but on the reversal of the switch the current in the coil F<2> is reversed and the coil therefore exerts a demagnetizing effect, causing the armature voltage to drop to a low value. In place of the aluminium cell, an automatic switch might be used which would close when the armature voltage coincided with the battery voltage, and would open when the armature current fell to zero.

Abstract: 10,892. British Thomson-Houston Co., [General Electric Co.]. May 24. Switches.-In a motor controller, consisting of a number of separately-actuated switches placed in series, each switch of the series, itself closing quickly, sets in action a dash-pot device which, after a certain interval of time, allows the switch next in order to be closed. On closing the master-switch S, Fig. 1, the actuating- coil a of the first switch of the series is excited. The switch, in closing, lifts a bar, connecting- the upper pair of auxiliary contacts 1, 2, and disconnecting the lower pair 3, 4, as the piston 9 carrying the lower bridge-piece 6 remains, during the quick upward movement, relatively immovable in the dash-pot 7 secured to, but insulated from, the upper bridge-piece 5. In the initial position, a large hole 11 is covered by the piston, a valve 12 opens inwards only, and a small hole 14 affords the only air escape. The bridge-piece 6, after being quickly raised, descends slowly, finally completing the exciting-circuit of the second actuating-coil b, Fig. 1. The air-holes may be adjustable in size. Specification No. 20,755, A.D. 1902, is referred to.

Patent GB-190624975-A (GB)
Title: Improvements in Pneumatic Despatch Systems.
Filed: 1906-11-06
Granted: 1907-05-23
Abstract: 24,975. Lamson Pneumatic Tube Co., and Giles, E. L. Nov. 6. Pneumatic d i s p a t c h apparatus.- In vacuum systems comprising sending and receiving tubes constantly in communication, a counterweighted bell is employed as the vacuum chamber in controlling connexion with an electrically-driven fan or blower. The lids of a station are arranged to shift in opposite directions a rack which prevents the lid of the .sending tube from closing pending the return of the carriers. Initially, with a vacuum in the system D, Fig. 1, the bell c is depressed in the tank C ; but as the carrier is driven on by the atmospheric pressure, the internal pressure rises, and the bell is pulled up by the annular counterweight 21, till a tappet on one of the chains operates a switch g so as to start the electromotor, which drives the exhausting-fan till the vacuum is restored. When the lid 1, Fig. 2, of the sending-tube A is closed, a bar 3, carrying a tubular rack 6 with a certain amount of play, is supported by a spring, so that a recess 15 takes an arm 14 on the knuckle of the hinge ; but when the lid is lifted, a second arm 13 depresses the rack and bar one step, and a detent 10, engaging a rack 8 at the top of the bar, prevents reversal, so that the lid will not completely close after a carrier has been inserted. When the lid 2 of the return tube B is opened by the returned carrier, the tail 19 of its lever 16 trips the detent 10 by the finger 12, to let the racks and rod rise again. The play of the tubular rack then allows the arm on the lid to take the next tooth of the rack if a second carrier is sent before the first returns. The pipe between chamber and blower contains a check valve to prevent ingress of air when the blower is at rest, and the pipe between chamber and transit tube contains a dirt-trap.
