Title: Improvements in Safety Mechanism for Elevators.
Inventor: BUDDENBOHN CHARLES LOUIS
Filed: 1900-09-11
Granted: 1900-11-10
Abstract: 16,122. Buddenbohn, C. L., and Speer, W. Sept. 11. Lifts; safety suspending or retaining apparatus.- Relates to safety mechanism for lifts or elevators which provides for the automatic arrest of the cage or car in the event of accident or derangement of parts, or when the hoisting-rope breaks, and provides an indicator for the condition of the working parts and means for arresting or stopping the car by hand. The flexible rock shaft 7 is mounted on the car, and has cams 8, Figs. 5 and 6, adapted to engage with the guide-rails 1, and is continuously vibrated by a governor-like piece of mechanism 25, which automatically throws the cams into locking engagement with the guides when the speed becomes excessive. The governor 25, Fig. 7, consists of the rotary shaft 27 with radiallyextending arms 36 having spring-pressed slide blocks 37, Fig. 9, adapted to be thrown centrifugally outwards by the rotation of the pulley 28. The vertical slide 42 acts on the lever 24, which is connected by a chain to a bell-crank lever 21 fulcrumed on the car, and operates the shaft 7 in opposition to the dead weight 19. The governor is driven by the shaft cord 29, which passes round the pulleys 30 and 28 and is weighted at the lower end. A hand-lever connected to the bent link 14 extends into the car, to serve by its vibration as an indicator and a hand-lever for stopping the car.

Patent GB-190124805-A (GB)
Title: Improvements in Electrical Measuring Instruments.
Filed: 1901-12-05
Granted: 1902-04-10
Abstract: 24,805. British Thomson - Houston Co., [Read, R. H.] Dec. 5. Current meters.-A measuring-instrument contains a current-carrying conductor mounted in a stationary magnetic field, the conductor being fixed at one end and connected at the other with an indicating-device. In the form shown in Fig. 2, two conducting ribbons or wires are used, formed into flat spirals 5, 6, which are coiled oppositely about an axle 2. The axle is attached to their inner ends, and is supported between jewel bearings 3, 4. It carries a light pointer over a stationary scale. The outer ends of the spirals are secured to circularly-adjustable insulated arms 7, 8, by which the current to be measured is passed through the spirals in series. The spirals are situated in gaps between the pole-pieces N, S, N of permanent magnets or electromagnets. The opposite coiling of the spirals on the axle obviates error due to temperature variations. In another arrangement, the current passes from the outer ends of two oppositely-coiled spirals to the axle, and thence to a fixed point by a third spiral, which is not in the magnetic fields ; the magnetic fields are directed alike.

Granted: 1902-12-04
Abstract: 24,845. Haes, H., and Finzi, D. Dec. 5. Points and switches operating from tramcars and other vehicles. The points are moved by wedges f lowered into the rail groove by the driver, a pair of wedges with their points lying left and right being placed in front of each wheel in the direction of motion. Between the wheels, the wedges may be double-ended, as shown at f<1>, Fig. 11, to economize space on vehicles running in either direction. Each wedge f is carried by a separate slide e, and one is raised while the other is depressed by the roller ends of a centrally-pivoted lever i. On each side of the vehicle all the levers i are connected by arms k and links l, and they are operated from the driver's platform by means of a vertically-lifted rod x<1>, link z, weighted bell-crank 1, link 4, rod t, and slotted plate s, rocking-shaft o, and link m. The Provisional Specification states that worm gearing may be used. The slides e are mounted in a box b hung at d on the underframe of the vehicle and controlled by the adjustable spring plunger 12. The roller ends of the levers i bear on the slides through intermediate springs, and these two spring arrangements allow for vertical and lateral play. The heel ends of the wedges are provided with friction rollers. To keep the box in position, a shoe 6, working in the rail groove behind the wedges, is carried by vertical guide-pins and springs 9 on the box. At each end of the vehicle there are two of the rods x<1>, each working its own side, and they have handles v which can be placed into upper, lower, or middle notches.

Title: Improved Apparatus for use in the Purification of Coal, Oil and like Gases.
Inventor: CLAPHAM WILLIAM SUGDEN
Filed: 1902-04-14
Granted: 1903-04-02
Abstract: 8618. Clapham, W. S. April 14. Purifiers.-Gas purifiers are formed of vertical chambers or tanks a containing grids b upon which iron oxide, lime, &c. may be placed. Gas is admitted through openings g at the bottom, and withdrawn through openings f at the top. The grids are charged in at the top and removed from the bottom, one or more at a time, so that the gas first passes through the grids containing the foulest purifying-material, and gradually passes to the freshest. To change one or more grids, a carriage t is run beneath the particular chamber a, and. a hydraulic or other lifting-jack v is raised to lift the door k, which is subsequently lowered, along with the jack, after its clamping- pieces have been removed. Another jack u is then brought up to lift the grids, and thereby free the holding - catches w, which are then rotated by the handles w<1>, after which the jack is lowered, so that one or more grids are brought below the catches. The catches are then again closed, and afterwards the door k is replaced. The grids are raised by a hoist p to the top of the chambers where there is a rail r carrying a block q by which a cover h can be removed. One or more grids are then placed in the tank, after which a hopper s, having previously been charged with fresh purifying-material, is also raised by the hoist, and discharged on the empty top grid or grids. On replacing the cover, the apparatus is again ready for use. The chambers may be horizontal or inclined, the grids being removed from and replaced at the ends. The Provisional Specification states that additional openings may be made into the tanks, so that purifying-substances may be inserted or withdrawn at or from either one or more positions.

It consists of a platform A, of a size to accommodate one person and paint pots, tools, &c., which is provided with foot straps A<1>, A<2> and an aperture for the passage of the rope H. On the underside of the platform are two brackets or frames, only one of which is seen in Fig. 4, serving as bearings for spindles B<3>, B<4>, on which are mounted clutch blocks C', C<2>, having hollow serrated faces engaging the rope, and weighted at their lower ends to make them tend to close together. The blocks are connected by links D to levers D', which can be raised into engagement with spring catches D<2> so as to disengage the blocks from the rope. A brake consists of a pulley E<3> and a pivoted blocK E, which can be moved by a threaded rod F to jam the rope between the block E and the pulley E<3>.
