Patent GB-190111720-A (GB)
Title: Improvements in Lubricating Apparatus.
Inventor: FAUL WILLIAM JOHN
Filed: 1901-06-25
Granted: 1902-05-01
Abstract: 11,720. Faul, W. J. June 25. Signals, bell and indicator.-In a lubricator for supplying oil &c. to the cylinders and steam chests &c. of engines, visible and audible means are provided for indicating the flow of the lubricant. A reservoir 1 has a cover 2 provided with an inlet 3 and an outlet 4 leading to the parts to be lubricated. A piston 12 for expelling the lubricant is operated by means of steam admitted through a pipe 8, a drain cock 11 being arranged in connection therewith. The piston-rod 13 terminates in a rack 14 gearing with a pinion on the shaft 16. On one end of the shaft is mounted a toothed wheel 20, which engages a spring wiper on one end of a pivoted lever, the other end of which carries a hammer adapted to ring a bell or gong 23. The shaft 16 is connected, through toothed gearing, with a shaft 29 on which is mounted a pointer 32 arranged to travel over the face of a graduated dial 33. In operation, the ringing of the bell indicates that the apparatus is working and also the rate of working, and the pointer 32 indicates the rate of feed and also the amount of lubricant that has passed. An arm 34, adjustably secured to the piston-rod, carries a rack in gear with a wheel 37. By turning the wheel 37 in one direction, the piston can be withdrawn to the bottom of the reservoir, and by turning the wheel in the other direction the flow of lubricant can be temporarily increased. When the lubricator is used in connection with a gas or oil engine or other motor not driven by steam, the piston 12 may be operated by worm or screw gearing, motion being derived from the main shaft. Instead of the rack 14 and pinion, an electric motor and a circuit closing and opening device may be employed for driving the indicating devices. In this case the piston-rod is fitted with a commutating device for intermittently actuating a switch or circuit closer and breaker. The continuous ringing or the cessation of the ringing of the gong indicates the stoppage of the appliance.

Title: Improvements in Variable or Change Speed Gear
Inventor: CARTER WILLIAM THOMAS
Filed: 1901-09-21
Granted: 1902-08-28
Abstract: 18,876. Carter, W. T. Sept. 21. Toothed gearing.-Relates to epicyclic gear in which an increase in the resistance to be overcome causes a change in the relative position of certain parts, and a consequent variation in the speed ratio. The driving-shaft a carries a loose bevelwheel g and a fixed bevel-wheel b, which are geared together by loose pinions d mounted in a loose carrier wheel c. The chain-ring f, or other part for transmitting the power, is mounted loose on the wheel c, and is driven by means of a spring i fixed in the wheel and bearing upon a stud l which is fixed in the ring and projects through a slot in the wheel. The loose bevel-wheel g is formed with a brake rim embraced by a band h secured at one end o to the chain-ring and at the other end p to the wheel. Normally the spring i keeps the chain-ring so far in advance that the band grips the rim and locks the bevel-wheel to the carrier, so that the entire gear rotates together. With increased resistance at the chain-ring it lags behind, slackens the band, and allows a certain amount of slip in the wheel, and the carrier advances at a lower speed. Fig. 5 shows a modification, in which the bevel-wheel g is replaced by a brake-wheel fixed to the shaft. In another arrangement, the pinions d are double ; the inner pinion gears with the wheel b, and the outer with a ring fixed to a loose drum upon which the chainring is mounted ; the brake band is applied to a drum fixed on the shaft.

Patent GB-190308803-A (GB)
Title: Improvements in Metallic Packing for Stuffing Boxes.
Inventor: CARTER CHARLES WILLIAM
Filed: 1903-04-18
Granted: 1904-02-18
Abstract: 8803. Carter, C. W. April 18. Stuffing - boxes.- Metal packing-ringsare formed in segments and are pressed on to the rod by bevelled rings acted on by springs. Fig. 1 shows a stuffing-box with two segmental packing-rings each composed of an outer ring 5 recessed to receive an inner ring 5<1>. These rings are divided into segments by V-shaped notches 10, Fig. 8. The notches in the inner ring 5<1> and the outer ring 5 are arranged to break joint. Relative movement is prevented by pegs 11. The packing rings are confined between unsplit rings 6, Fig. 1, and the bush 3 and gland 4, and the outer rings 5 are pressed on to the rod by central bevelled rings 7, which are pressed apart by springs 9. The joints between the rings 6 and the bush 3 and gland 4 are packed by plastic washers 8. All the joints except those between the rings 5 and the rings 7 or 6, may be at right-angles to the rod 1. In the latter case, the packing may be floating, i.e., the packing-rings fit the rod 1 closely but not the stuffing-box 2, while the rings 6 fit the stuffing-box but not the rod. The rings 6, 7 may be split to facilitate their insertion, and, in this case, the halves are joined by screws 12, Fig. 3, with countersunk heads. When the rings 7are floating and are split, a recess in one receives a ridge 14, Fig. 4, on the other, and so prevents the rings from opening. Relative motion is prevented by studs 15 passing through holes in one ring 7 and screwed to the other. These studs also limit the extent to which the rings 7 can be separated by the springs 9. The rings 6, Fig. 1, may be dispensed with, and, in some cases, the rings 7 are also dispensed with. In the latter case, the two rings 5 are formed in one, and are pressed towards the rod by the bevelled faces of the bush 3 and gland 4.

Title: Improvements in and relating to Boot-making or Boot-finishing Machines.
Inventor: CATT GEORGE HENRY
Filed: 1903-07-10
Granted: 1904-05-05
Abstract: 15,334. Catt, G. H. July 10. Belt forks, operating. - In a boot-finishing machine having a capstan d, fitted with a number of cutters e, as described in Specification No. 7168, A.D. 1903, [Abridgment Class Boots &c.], the capstan is mounted upon a second shaft g, which is provided with means for engaging and disengaging the cutters and for controlling the driving-shaft. In the position shown, a cutter e is driven by the shaft a through a clutch r. When it is desired to change cutters, a hand-wheel i is rotated and a pin k travels round a cam-shoulder l. This allows a spring g<1> to move the shaft g and capstan d longitudinally and so to disengage the cutter spindle f from the driving-shaft. At the same time, the shaft has been stopped by a worm thread m which, being fixed to the shaft g and gearing with the belt fork n, moves the fork and throws the driving-belt over from the fast pulley b to the loose pulley c. The capstan can now be rotated and another cutter brought opposite the driving- shaft, when, by rotating the handle-wheel i in the opposite direction, the cutter is first engaged with the shaft a and the belt then passed on to the driving-pulley b.
Patent GB-190315514-A (GB)
Title: Electrical Alarm Device for Indicating the Fall in the Level of Liquids contained in Closed Vessels or the like.
Inventor: MEYER GEORG ALBRECHT
Filed: 1903-07-13
Granted: 1904-07-07
Abstract: 15,514. Meyer, G. A. July 13. Water and other liquid levels, indicating.-An electric alarm indicates the lowering of the level of a liquid in a closed vessel, such as a boiler or the like. On a lowering of the level, the resistance of an electrical current, a portion of which is formed of wires depending into the liquid, is increased, with the consequent diminution of the circulating current. This diminution serves to open a relay and to sound, directly or indirectly, an alarm. As shown in Fig. 1, the fall of the water in the gauge glass 8 increases the electrical resistance between the conductors 1, 2, with the result that the needle 14 of the galvanometer 12 moves to close the circuit in which the alarm 18 is situated. A switch may be placed in the alarm circuit. To delay the sounding of the alarm, the relay current may heat the wire 21, Fig. 4, which envelops the thermometer 19. By the rising of the mercury in the thermometer, the alarm circuit is closed. One battery only may be employed for both circuits, as shown in Fig. 5, which also shows the automatic switch 24 for breaking the circuit 21 when the thermometer has sounded the alarm 18. A U-shaped thermometer, having its mercury norir.ally at the bend, may be employed. Where a mercury thermometer is undesirable, a mechanical contact thermometer may be used, the thermometer consisting of a bar composed of two metals having different coefficients of expansion and surrounded by a heating-coil. To protect the wires in the gauge-glass and to prevent short-circuiting, the wires may pass into the glass under a tightly-fitting india-rubber sleeve or may be insulated by the closing-plug or may be fused through the glass. Within the glass, the wires, of convenient form, may be embedded in suitable insulating tubes or material.

Title: Improvements in Electric Traction
Inventor: SAYER ROBERT COOKE
Filed: 1903-08-21
Granted: 1904-08-18
Abstract: 18,076. Sayer, R. C. Aug. 21. Electric railways in which the locomotive runs on a single rail, rope, or cord and is supplied by current from a shoe which runs in a slot in a rail, the rail forming the conduit, are described. The locomotive is made in the form of a light or heavy wheel or drum as shown lin the sectional elevations, Figs. 1 and 2, the bottom portion only being shown in Fig. 2. The rim portion a, b of the wheel revolves, running on a guide or track, while the sides m, n remain at rest relative to the rim and carry the stators t of the motor. The rotor rr drives the vertical shaft r which, through the gearing k, s, drives the rim. The sides m, n support this shaft in the bearings q, pb. The connection between the rims a, b is through the circumferential springs e and pieces f. To vary the power of the motor the rotor is made to move more into, or out of, the stator by turning the handle u which raises the screws qq. The current is supplied to the motor from a shoe or collector shown with the rail in longitudinal sectional elevation in Fig. 7, and in transverse sectional elevation in Figs. 8 and 9. The shoe has three collectors with the corresponding leads vk, vc, vg leading to the motor ; the centre collector ve takes a high voltage current from the conductor yb for the use of heavy wheels, while the collector vh takes a low voltage current from yc when the wheel is light. The collector vl and conductor yd is for the return. The shoe is made to run steadily by the springs vz, and arms vo carrying the rollers vs which run on the underside of the rail yy. The links va connect the shoe to the motor wheel. Fig. 13 shows a sectional plan of the shoe at the point where it fits into the slot of the rail. The pilot vt makes a slot by separating the spring pressed metal strips ym, yn. In the case of very high voltages the lower conductor is covered by an insulating-ribbon yw, Figs. 16, 17, which is raised by the collecting-wheel ve as it moves along the conductor. The rail is made in two parts which are fixed together by bolts, and portions are constructed so as to be quickly detachable for the insertion of the collecting-shoe. The lower flanges are for securing the rails to the bedding.

Granted: 1905-02-09
Abstract: 4262. Foster, J. Feb. 20. Gates and gateposts.-Relates to gates for shop and other doors, and consists chiefly in pivoting the posts on horizontal spindles so that they may be closed down into a box below ground. The gates may be collapsable and detachable or non- detachable, or they may be non-collapsable. Fig. 1 shows a part of a collapsable and non-detachable gate, Fig. 3 a plan of the shoe with the posts e closed down horizontally, and Figs. 4 and 7 end view and plan respectively showing the post erect. To close the gates, they are run back on the rails G', G<4>, and the latter are turned about their pivots G<2>, G<5>. The post e is then moved along the spindle a by means of the cam h, which takes in a slot i, and is operated by a lever g. The arms e<1>, e<2> are thus removed from the stop b<5> and the slot b<4> respectively, so that the post is free to be turned down. As this is done, the inclined planes b<1>, b<2>, bearing against the toes e<1>, e<3>, slide the post still further along its spindle. When closing the gate, the inclined plane b<3> forces the post in the opposite direction.

Granted: 1904-08-25
Abstract: 4795. Hocquart, E. L. Feb. 26. Lifts.-Relates to moving stairways and the like, and their hand-rails. Fig. 1 shows the lower end of the stairway, Fig. 8 a cross section of a step, and Fig. 11 a plan section of the step chain. The steps 18 are mounted between two endless chains, and are supported by rollers 21, 22 running respectively on tracks 37, 38 on the walls of the casing. Each joint pin of the chain is connected to a step and also carries' one of the rollers 21. The other rollers 22 are mounted nearer the centre of the stairway. The chains are driven by chainwheels at the top of the stairway, and at the bottom they, and the steps, are guided entirely by the tracks 37, 38. Owing to this arrangement, the tracks cross at two points. At the lower point, a switch having a rib 39 forming a continuation of the track 38, is provided, pivoted at 40 and normally held in the position shown by a spring The switch, after having been opened by the passage of a roller 21, is returned gently by the engagement of its inclined face 41 with the roller spindle. At the upper crossing there is no switch, but the step is partly supported on a rib 48, Figs. 1 and 3, while its roller 22 is crossing the track. Just before this crossing the track 38 has a sharp bend, and the rollers 22 are guided there by means of a spring-pressed flange 44 which springs into place under the roller after the latter has passed. The landings are horizontal and grated, and the steps are formed with corresponding ribs so that they rise through the lower landing to pick up passengers, and, after travelling horizontally slightly above the upper landing, sink through it to deposit passengers. The chain is of the flat-link or Galle type, having the alternate links 26 each formed in two parts with eyes 26<1> fitting halfway into the eyes of the other links 25. The flexible hand-rail consists of blocks 56, Fig. 12, connected by flat steel strips 57 covered by wooden strips 59 half sawn through at intervals, the whole being covered with a cloth &c. covering. The hand-rail is connected to an endless chain 62, driven at the same speed as the stairway, and guided, except at the curved parts of its run at top and bottom of the staircase by a track 67, Fig. 5, which prevents both vertical and lateral movement. The hand-rail is kept parallel to the chain, except at the curved parts, by means of arms 64 adapted to slide lengthwise in the guideway 67, and fixed to the spindles 58 by which the hand-rail is secured to the chain. In a modification, the chain 62 is omitted and the hand-rail is fitted with blocks adapted to engage the teeth of a sprocket driving-wheel and to slide on fixed guideways.
