Patent GB-190728436-A (GB)
Title: Improvements in Electric Signalling on Railways and Controlling Trains Independently of Drivers.
Inventor: GARDINER ALEC
Filed: 1907-12-27
Granted: 1908-10-08
Abstract: 28,436. Gardiner, A. Dec. 27. Stopping engines and trains; contacts, mechanical ; contacts, electric re- Cording signals. - For the purpose of notifying the driver when he is on a section of line requiring reduced speed, ramps are placed on either side of such section, the first ramp co-operating with engine apparatus to exhibit a warning- signal, which remains in view until the second ramp is passed. A recorder may be provided to record the time and duration of the signal exhibition, together with a means for cutting off steam or applying the brakes, and an audible signal.- The engine apparatus is shown in Fig. 3, and consists of a magnet M, the armature of which carries a disk S, which shows through a window when the armature is free. The armature, when raised, is held in its raised position by current flowing from a battery B<1> through a contact C<1>. When the engine contact is lifted on a ramp R<1>, this circuit is broken at a contact C<2>, and the armature falls. The ramp R<1>, Fig. 1, is placed at the beginning of the section, and a ramp R<2> at the end is connected to one pole of a battery B<2>, the other pole of which is connected to a rail. When the engine reaches R<2>, current flows from the battery B<2> to the magnet M through a lead E, and the armature is raised although the local circuit is broken at C<2>. In the case of a branch leaving a main line, the branch alone requiring the reduced speed, the first ramp R<1> is energized from the battery B<2> only when the points are set for the main line and the armature is held up. An additional contact C<3> closes the circuit of the magnet M<2> when the armature falls, and so causes a pen I attached to the armature of the magnet M<2>, to record the time and duration of the signal on a chart stretched over revolving cylinders. Any other construction of recorder may be used. The falling of the armature also breaks, at C<4>, the circuit of an electro-magnetic valve V to cut off steam or apply the brakes, and closes, through the contact C<3>, the circuit of a bell or buzzer Z. In order that the driver may be able to restore his motive power or remove his brake when speed has been sufficiently reduced, a parallel automatic contact C<5> is provided, which is closed by a governor G when the speed is thus reduced. The driver may then complete the valve circuit at the contact A by means of the handle H. For single-line working, a 'dead' track device is provided on the approach side of the section, and means, such as a polarized relay controlling a two-way switch, are provided in the circuit of the pair of staff instruments, to ensure that all the track contacts except the one last passed by a train leaving the section, shall be 'dead.' The track devices may be of a temporary nature, and the same recorder may be similarly used to record the time and duration of cab signals, such as described in Specification No. 22,357, A.D. 1905.

Title: An Improved Method of and Means for Testing the Accuracy of the Sighting Apparatus of Ordnance.
Inventor: BURNS WILLIAM ALBERT
Filed: 1908-08-18
Granted: 1909-08-12
Abstract: 17,371. Burns, W. A. Aug. 18. Optical instruments; telescopes.-For testing the parallelism of the line of sight and the bore of the gun at zero elevation, and also the graduations of the range and deflexion scales, and the accuracy of the permanent drift correction, a mirror is mounted at the muzzle of the gun with its plane truly perpendicular to the axis of the bore, or at a known inclination thereto, and the sighting-telescope is replaced by a testing-telescope A constructed as shown in Fig. 1 with cross-wires at X and an external pointer B, the tip of which is in the optical axis of the telescope. In small guns, the mirror C is set perpendicular to the bore, and if at zero elevation of the gun and sights, the image of the tip of the pointer, seen through the telescope, appears at the point of intersection of the cross-wires, the line of sight and the bore of the gun are parallel. Fig. 7 shows an arrangement for use with larger guns in which the sighting-apparatus is at a distance from the gun. The testing- telescope A, constructed as described above, is pivoted at a in a frame a<1>, which in turn is vertically pivoted at e<1> upon the sight bar E. The mirror C is mounted upon an axis H supported in bearings in arms g attached to the muzzle D of the gun. The initial adjustment of the mirror with its plane perpendicular to the axis of the bore is made by sighting cross-wires or a small aperture in an attachment K at the breech end of the gun through a telescope J rigidly secured to the axis H. The mirror is then tilted through a suitable angle, indicated by a pointer L<1> on a scale L, and the telescope A is turned upon its trunnions a until the image of the tip of the pointer B in the mirror C is seen at the point of intersection of the cross-wires X. If the angle recorded by a pointer a<3> upon a scale a' is the same as that through which the mirror has been tilted, the zero axes of the gun and sights are parallel. The range graduations on the sighting-apparatus are afterwards tested by adjusting the sight-bar E for a given range by the sightelevating gear, and sighting the image of the pointer B by swinging the telescope A about the pivot a. If the angle through which the telescope is thus swung is the same as the known angle of sight elevation which corresponds to the given range, the range graduation is accurate. The deflexion graduations are similarly tested by lateral displacements of the telescope A and the frame a' about the pivot e<1>. As the axis e<2> is inclined to give the permanent drift correction, the accuracy of this correction is tested when testing the range graduations since it is necessary, in order to cause the image of the pointer to coincide with the intersection of the cross-wires, to swing the frame a<1> about the pivot e<1> to neutralize the lateral displacement given to the line of sight by the inclination of the axis e<2>.
