Patent GB-190310723-A (GB)
Title: Improvements in the Control of Electrically Propelled Vehicles.
Inventor: RAWORTH JOHN SMITH
Filed: 1903-05-11
Granted: 1904-03-31
Abstract: 10,723. Raworth, J. S. May 11. Motors, controlling. -Relates to vehicles propelled by motors having two circuits, a n armature and a shunt field circuit, and controlled by apparatus of the kind described in Specifications Nos. 3657 and d 3658, A.D. 1903. The object is to limit the reduction of the field when altering speed, so as to prevent the ratio between the current strengths in the armature and field, necessary for sparkless working, from being exceeded. Another arrangement is also described for coupling some series winding in circuit with the armatures when the motors are changed from series to parallel working. As shown in Fig. 1, the solenoids 13, 14 are in circuit with the armatures and the shunt field windings respectively, the cores 9, 10 being carried by the pivoted lever 11 connected to the pawl 7 on the controlling- handle d. When the handle d is moved to that position at which the limit between the armature and field strengths for sparkless working is reached, the core 9 is drawn down, and the pawl 7, engaging the rack 8, prevents further movement of the handle. A modification is described in which a third solenoid is fitted, normally short-circuited, and movement of the lever carrying the cores of the other solenoids allows a current to pass through the third solenoid, causing the locking-pawl to engage the rack. A differentially-wound solenoid may be employed in place of separate solenoids. Fig. 4 shows an arrangement for cutting out resistance in the shunt circuit and introducing resistance into the armature circuit. The resistances s, c are in circuit with the shunt field windings b and the armature a respectively. The solenoid 13 is in series with the armatures, and the solenoid 14 is in series with the field windings, and, when the ratio between the strengths of the currents in these exceeds the limit for sparkless working, the core of the solenoid 13 is drawn down, thus removing the bridge 23<a> from the contacts 25 and introducing the resistance 24 in circuit with the armatures. A series winding to augment the field may be used.in place of the resistance 24. Fig. 5 shows an arrangement for introducing some series turns to augment the fields, when the motors are changed from series to parallel working. The motor armatures a are in series, being connected together by means of the switch 27 carrying a connecting-piece 30 bridging the terminals 28, 29. By moving the switch to connect the terminals 31, 32, the armatures a, a are coupled in parallel, and, at the same time, the series windings v<2> are introduced each in circuit with an armature.

Granted: 1905-05-04
Abstract: 13,841. Muir, J. June 18. Measured quantities, delivering; measures of capacity.-Granular or pulverulent materials are measured into packets, boxes, or bags from a hopper c which is moved across the top of a series of measures g by a screw k. These measures may be of constant capacity, or telescopic, and their lower ends are fixed to a tray s, the height of which in the latter case can be adjusted by screws and bevel gear. This tray has holes corresponding to the measures and closable by a slide 3. Beneath this slide are grooved bars 12 to support flexible spouts (not shown) which may be weighted, and be contained in frames. These deliver the material into another series of funnels 8 contained in a tray 9. This second tray can be raised by a hand-lever actuating cranks with links connected to the tray. The lever is held by a ratchet device and by adjustable stops. Beneath the funnels 8 is a drawer 11, the sides of which are grooved to receive adjustable bars or slats. These bars are half or two-thirds the depth of the drawer, and divide it into compartments to receive the packets &c. 10. A spot is placed on the bottom of the drawer beneath each funnel, and the sides may have scales to assist in placing the bars. When cloth bags are used, wire frames may be employed in place of the bars, having hooks at the top to hold open the bags. The hopper contains triangular cross-bars and is provided with rubber flaps to strike the measures, and a foot-lever 30 is added which may work a cam lever or plunger, which comes against a resilient stop on the packet drawer 11, and shakes it. Or the drawer frame 32 itself may be raisad and let fall, resilient packing 34 being provided. The drawer 11 may also be suspended or slung upon springs to assist the shaking. Additional funnels may be placed in the mouths of very small packets, and the sides of the drawer 11 raised by extension. pieces for large ones. Tables 39, 40 may be added, having rollers 41, 42 to aid in moving the drawer, and the capacity of the measures may be indicated by a pointer on the upper tray s movable over a scale fixed to the main frame. Cylindrical extension pieces may be added to the measures if required. The Provisional Specification states that the packet drawer may be vertically adjustable.

Title: Improvements relating to Steam Valves.
Inventor: BOBY WILLIAM
Filed: 1904-07-18
Granted: 1905-06-08
Abstract: 15,904. Boby, W. July 18. Actuating valves and cocks.-In order to regulate the admission of steam to the water-softening apparatus called the " Chevalet - Boby Heater-De- "tartariser," or to other apparatus, an equilibrium or other steam valve is operated by a pivoted lever, one end of which is weighted and held back by an adjustable spring, the other end of which is fitted with a water vessel supplied with water through a pipe k, Fig. 1, from another part of the apparatus. In the application shown in Fig. 1, when the pressure of steam in the top section A is in excess, water is forced out through a pipe g into a funnel i, and runs through the pipe k into the vessel b. The lever consequently descends and shuts off the steam from the apparatus. The pressure is thereby reduced, and, as the flow of water is stopped or so much reduced that the vessel b gradually empties by the holes c, c<1> one end of the lever d rises and gradually opens the valve for the re-admission of steam. In a modification, shown in Fig. 3, the pipe g which is connected to the bottom section B of the apparatus is fitted with a lever pipe h by a swivel joint l so that the height of the delivery end of the pipe h can be adjusted by band to vary the limit pressure inside the apparatus. A strainer is fitted in the water vessel b to prevent the leakage holes from being choked. The height of the delivery end of the pipe h may be adjusted automatically by connection with a pivoted and weighted lever fitted with a second leakage vessel, which is supplied with water. To ensure a positive pressure in the top section A of the apparatus, a weighted check valve, such as a hinged valve, is applied to the vent or outlet pipe from the top of the apparatus.
