Title: An Improved Form of Electrically Actuated Railway Signal.
Inventor: LANGDON WILLIAM EDWARD
Filed: 1899-07-24
Granted: 1900-07-14
Abstract: 15,166. Langdon, W. E. July 24. Semaphore &c. signals; Lamp signals; signalling and communicating between trains; indicators and repeaters, signal.-The line signal consists of a rectangular case A,with a glazed front, within which is pivoted a frame B covered with a semi-transparent material, preferably red. In the normal position, this frame hangs vertically behind the glazed front, to give a danger' signal. The frame is partially balanced by a counterweight e, and to give a 'line clear' signal is raised to the position shown in dotted lines at g, Fig. 2, by the action of the electromagnet K, the armature I of which is connected by the rod h<1> to the arm h on the spindle of the frame. When the frame is raised, the colour signal is removed, and the white or other backing of the case is visible through the front. The return of the frame to the normal position is effected by gravity, which may be aided by a spring connected to the armature I &c. For night work, the casing is illuminated by a lamp L. The circuit of the electromagnet K may be closed and broken by a switch in the signal cabin, or, as shown in Fig. 6, it may be broken by a train passing over a contact-maker d. The line circuit L through the electromagnet is closed by the switch H in the cabin, and by the tongue b of the polarized armature A engaging the contact c. When a train passes over the contact-maker d, a local circuit e is closed, which reverses the relay, causing the tongue b to make contact with c' and to break the line circuit. A second switch H<1>, controlling the line L<1> through a second set of windings on the relay coils, is provided for restoring the relay tongue to operative position. The switches H, H' may be operated by hand, by the operation of the ordinary signal levers, or by the train passing over a second contact-maker &c. For indicating the position of the signal to the signalman, the frame B is provided with a contactmaker 0, Fig. 8, which completes, with the spring p, or the spring p<1>, the circuit L through the ordinary electrical repeater I in the cabin.
Patent GB-189917997-A (GB)
Title: Improved Means for Stopping Railway Engines and Trains Independently of the Drivers and Guards.
Inventor: COATES WILLIAM ARTHUR
Filed: 1899-11-01
Granted: 1900-10-06
Abstract: 17,997. Coates, W. A., and Bevan, T. Nov. 1. Brakes.-Relates to means for stopping railway engines and trains independently of the drivers and guards, when they pass a signal set adversely. Two rods on bars M pivoted at their adjacent ends are mounted on the permanent way, and are operated by levers K &c. from the ordinary signal connections, so that, when the signal is put to ' danger,' the rods &c. are raised into position to move the lever B on the engine &c. The upper flattened end P of the lever B is adapted to close the valve chamber V, which communicates with the vacuum brake system, and also to close the port Q, which communicates through the pipe R with the cylinder T connected to the steam whistle, and through the narrow passage Y with the brake system. Two sets of bars &c. M are employed, of which the second is arranged to be raised to a higher level than the first. When in operative position, the first set displaces the lever B sufficiently to open the port Q, which breaks the vacuum maintained through the passage Y in the pipe R, and so causes the piston of the cylinder T to open the whistle. The passage Y is not sufficiently large to effect the application of the brakes. Should the train not be stopped before reaching the second set, the lever B is displaced to a greater extent, so opening the port V and applying the brakes. In this case, the lever B is locked in the position to which it is moved by a spring catch engaging one or other of the projections X. The bars M may be replaced by a single flexible bar, which is bowed upwards by the action of the lever K. The apparatus is also applicable for use in connection with steam pressure or electromagnetic brakes.

Title: Improvements in or relating to Propelling and Steering Devices for Motor Road Vehicles.
Inventor: BOULT ALFRED JULIUS
Filed: 1900-05-01
Granted: 1900-08-25
Abstract: 8051. Boult, A. J., [Collins, J. P.]. May 1. Motor road vehicles.- Relates to propelling and steering devices for electricatly-driven motor vehicles. Fig. 6 is a side elevation and Fig. 5 a front elevation, both partly in section, and Fig. 3 is a perspective view of the motor and driving-gear. The motor support 9 is pivoted on the rear axle, and carried at the front end by springs 11. The principal motor 12 consists of a field frame having polepieces provided with field coils 19. 20 and a middle removable pole-piece 21, dividing the frame into two compartments in which run two independent drum armatures. These drive the rear wheels separately through worm gear contained in casings 34. The fore part of the carriage is supported on an axle casing consisting of flat plates 40, 41 suitably connected, to which are pivoted blocks 43, through which pass the steering- axles 6, 7. on which the steering-wheels are free. The steering-axles can be adjusted angularly by the hollow steering-post 49 through the medium of a wheel 52<a> loosely connected to them. Through the steering post passes a vertical bar 55, which can be raised and lowered by the steering-handle 60 in order, first, to operate a speed-controller 67, and secondly, to operate brakes 75 on the motor shafts through the connections 80, 79, &c. Movement of the steering-handle 60 to right or left to adjust the steering-axles 6, 7 also, through the medium of the switch 69, 70, effects corresponding control of the motors, accelerating the armature on the outer side of the path to be traversed and retarding the one on the inner side. The arrangements of the contacts and circuits for effecting this are set out in the Specification, shunts of various resistance being put into the field on one side, and portions of the field coils being cut out on the other side. A reversing-switch is indicated at 111. Provision for manoeuvring the vehicle in a contracted space is made by furnishing the front or steering-wheels with small motors 94, 95 and arranging for the turning of the fore-carriage through a right-angle. The fore-carriage is turned by means of a hand-wheel 86, normally being looked in the position shown by a pawl 90.

Title: Improvements relating to Tune Sheets for Automatic Musical Instruments, and to similar Operating-Devices; and Apparatus Controlled thereby.
Inventor: O'CONNOR JAMES
Filed: 1900-08-16
Granted: 1901-07-06
Abstract: 14,702. O'Connor, J. Aug. 16. Automatic instruments.-The invention relates to perforated sheets and to means for driving them, applicable amongst other things to automatic musical instruments, and it consists in providing against expansion and contraction of the perforated sheet and in means for causing it to travel accurately. Fig. 2 is a plan of a tracker board of a musical instrument, the holes e in which increase in width outwards from some specified point, the centre in this case. The holes b in the tune-sheet, Fig. 1, are all of the same width, but are spaced apart to correspond with the distances between the centres of the holes of the tracker board. The result is that, provided that the tune-sheet is accurately guided at the middle, changes in its size due to lateral expansion or contraction make no difference as regards the uncovering of the proper holes, and the uncovering by a hole in the tunesheet of a hole in the tracker board adjacent to the proper one is avoided. In another form, the holes belonging to the same note in different octaves are placed adjacent to one another in the tracker board, spaces being left between the groups so formed. The tune - sheet is correspondingly perforated, so that any shifting which occurs can at most only cause the same note to sound in a different octave as well as in the proper one. Fig. 14 shows the device for guiding the tune-sheet centrally. Special holes s, s, which may be adjustable, are uncovered by one or other edge of the tune-sheet if it fails to travel truly, thus operating one or other of a pair of pneumatics n, n. Arms actuated by the pneumatics engage with collars m, m on the take up roller g, which, subject to the guidance of the arms, can move longitudinally. The pneumatics are so adjusted that any failure on the part of the tune-sheet to travel truly is corrected by the shifting of the roller g. The tracker board can also be adjusted with respect to the bearings of the rollers by set-screws u and v. A device is also shown for doing the same thing electrically, and another device causes arms provided with half-nuts to engage with the screwed spindle of the roller, which is thus moved laterally.
