Patent GB-190320848-A (GB)
Title: Improvements in and relating to Traveling Stairways.
Inventor: BALTZLEY EDWIN
Filed: 1903-09-28
Granted: 1904-02-18
Abstract: 20,848. Baltzley, E. Sept. 28. Lifts ; elevators. -Relates to travelling stairways of the kind in which grated steps interpenetrate fixed grated landings, and consists essentially of means whereby a step rises through the lower landing as nearly vertically as possible to pick up the passenger, reaches the upper landing and deposits the passenger by dropping through the landing as nearly vertically as possible. The reduction of horizontal speed at the beginning and end of the journey, necessary to the avoidance of shock to the passenger, is obtained by making the motion of the step at these points nearly vertical. Before depositing the passenger, the step may be inclined so as to give him an impulse to step forward ; but to avoid accident should he neglect to do this, the step becomes parallel with the landing before disappearing. The landing also may be inclined forwardly. Figs. 7 and 12 show one form of the apparatus. The steps 6 are pivoted by their forward edges to an endless chain. The other or free edges are guided in a groove 30, Fig. 12, by which the inclination of the steps is controlled. The groove 30 is within a wider groove 20, by which the edges pivoted to the chain are guided. The grooves 20, 30 are formed in the side frames.of the stairway, and both are preferably continuous. The steps may be pivoted to the chain by either edge or at the middle, and modifications in the form and relative arrangement of the guiding- grooves may be made. The chain of steps, instead of returning as shown in Fig. 7, may run under the central part of the landing, and then emerge to form a descending stairway. The upper and lower landings are preferably connected by a grating, and the whole is vertically adjustable for wear. Fig. 4 shows one of the chain links. It is recessed at 5 to allow for movement of the free edge of the step, and has recesses 8, 37 in one or other of which the teeth of the sprocket-wheels engage. To guard against accident through breakage, more than one chain is used. Fig. 9 shows one form of step. It comprises boxes 9 strung together between distance-pieces on rods 10, and each ribbed at the top to hold a rubber or other tread. Other forms of step are described. The steps are bevelled towards their forward edges to lessen the chance of passengers tripping against the stationary landing. The grating bars of the landings are somewhat similar to the boxes 9. The sprocketwheels are preferably six-toothed. Their disposition in relation to the landings may be varied to obtain the required reduced horizontal speeds at the landings. The hand-rail consists of sections 61, Fig. 21, each carried by a step. At the top and bottom of the stairway, covers or casements are provided for the hand-rail. The surface 65 of that at the top intersects the hand-rail in the manner shown, so as gently to lift off a passenger's hand.

Granted: 1904-08-18
Abstract: 21,140. Isdale, M. G. Oct. 2. Signals, marine and ship.-Relates to electric apparatus for giving an alarm signal when the engines are working in the contrary direction to that shown on the order telegraph, and for indicating on the bridge the direction in which the engines are working. A two-way switch on the dial 2 in the engine-room, and a second two-way switch 7, operated by a connecting-rod 6 from the wiper shaft 5, co-operate when the shaft is turned in the wrong direction to allow a current from a battery 11 to pass to a bell 12 in the engine-room. A two-way switch 16 operated by a connecting-rod 18 from the arm of the switch 7 causes a current to be sent to the indicator 13 (shown in detail in Figs. 2 and 3) on the bridge, to indicate the direction in which the engine is working.
Patent GB-190321667-A (GB)
Title: A New or Improved Process for the Removal of Fat Extracting Solvents, from Materials.
Inventor: BERGMANN EUGEN
Filed: 1903-10-08
Granted: 1904-09-15
Abstract: 21,667. Bergmann, E. Oct. 8. Resins.-In the extraction of fats, oils, resins, or similar substances from animal or vegetable materials, the fat &c. extracting solvent is completely removed from the treated material by replacing it by a liquid which neither dissolves nor chemically alters it, and for which the material has a greater molecular attraction than for the solvent. The replacing-liquid is usually water, to which, however, acids, alkalies, or salts may be added to increase the molecular attraction between it and the material. In some cases these acids &c. may be applied to the material before it is treated with the solvent, and in such cases gases, such as sulphurous acid or ammonia, may be employed. The extraction of fat from skins or leather cuttings &c. by mean's of benzine or benzol is given as an example for the first method ; the benzine &c. containing the fat rises to the surface when water, either with or without hydrochloric acid, sulphuric acid, sulphurous acid, soda lye, or magnesium chloride, is added, and the benzine &c. remaining in the pores of the leather &c. is driven out by the water.

Title: Improvements in Regulating Dynamos Motors and like Electric Machines.
Inventor: MUELLER ALBERT RICHARD
Filed: 1903-10-20
Granted: 1904-03-10
Abstract: 22,673. M³ller, A. R. Oct. 20. Armatures ; field magnets dynamos, regulating; motors, controlling.-Relates to the regulation or controlling of dynamos, motors, rotary converters, &c. The field magnets or stators are divided into two sections relatively movable, and the two sections may act in unison on the armature windings or may act more or less in opposition. In some arrangements, the armature or rotor may have divided windings adapted to act in a similar manner. Fig. 1 shows a simple arrangement, in which 1, 2 are the ordinary field magnets, 4 a Pacinotti ring armature, and 5 an auxiliary or additional field magnet wound with coils 6 in parallel or other desired arrangement with the main field circuit. By partly rotating the field magnet 5 the resultant magnetic field may be varied. Fig. 4 is a diagram of an arrangement suitable for a polyphase machine, in which the armatures 13, 14, 15 and 16, 17, are mounted on a common shaft, and the fields 7, 8, 9 and 10, 11, 12 are connected in parallel but are relatively movable. Fig. 7 shows a construction of a somewhat similar machine. One field 31 is fixed to the frame 35, and a second 32 is mounted on a carrier 34 adapted to be moved by a worm gear 39. The armature or rotor 28 may be of the squirrel-cage type, and may have cores and windings 29, 30. In order to start, the two field windings 31, 32 are adjusted relatively to each other until the lines of force produced by the lower halves have opposite directions, and the full current can then be turned on, there being no armature current, in consequence of the opposed action of the two parts of the exciting-field. The field windings can then be adjusted so as to give any desired current without the use of switch resistances &c. In the form shown in Fig. 9, the machine has two fields 54, 55 and the rotor has two windings, viz., 50 influenced by the magnet 54 only, and the other 51 passing through the fields of 54 and 55. Fig. 8 shows another construction, particularly adapted for a four-pole rotary converter, the rotor having two windings, a ring 41 and a drum 42.

Granted: 1905-07-20
Abstract: 27,530. Marks, G. C., [Goldman, G.]. Dec. 16. Padding.-In a machine for finishing the surfaces of garment pads, the latter are fed on endless belts 14, Fig. 2, trough-like in cross-section, between a rotating roller 2 and a table 12, both of which are heated by steam. The principal feature of the invention consists of devices for presenting the pads a second time to the roller after having been finished on one side at the first operation. The pads are fed on to a belt 14<a>, Fig. 3, nnder the roller 2, being finished on the upper surface. A series of endless belts 24, Figs. 2 and 3, receive the pads and carry them down on to a revolving table 27 having projecting annular ribs. The pads are carried round on the table until partially lifted by fixed fingers 37, when they are received by other rotating belts 28, 29, carried upwards, and deposited with their unfinished surfaces in contact with the roller. They are then, by the motion of the roller, carried down on to the band 14, and finished on the other surface. From this band they are delivered on to a collecting-band and carried off to a receptacle. The second finishing operation may be dispensed with. The table and belts are rotated by a belt 36 which passes round the belt roller 30, round the table, and round a belt roller 25, returning over pulleys 34, 35. The roller 30 is driven by friction or other gearing from the band roller 16. The bands 14,14<a> may be replaced by one broad band, the two distinct finishing- operations taking place at opposite edges.
