Title: Improvements in or relating to railway signalling systems
IPC: B61L23/16
Filed: 1920-02-07
Abstract: 163,418. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. Feb. 7, 1920. Combined electrical and mechanical systems, non-automatic; electrical systems, non-automatic.-In a railway signalling system, the controlling-devices are supplied from a local track circuit which is energized by a battery in response to the transmission of a momentary current through the main track. In the arrangement shown in Fig. 1, the connections are indicated for trains travelling from B to A along the lower part of the double track. The track is divided into sections by insulators 2, 3, 4. To ask the man at A to accept a train, the man at B depresses the key 5, thus allowing current to pass from section 6 of the battery through the keys 5, 10, the bell' 11 at A, and the indicator 12. The bell rings, but the indicator is polarized and does not operate with current of this direction. To accept the train, the man at A presses the push 13 and the battery 14 sends a current through the track relay 16 and a switch 15 controlled by the starting- signal lever. If there is no train already on the section, the relay raises its armature 17 to connect the batterv 19 across the local section 18 of the track and thereby to energize the local track relay 8, which raises its armatures. The armature 22 closes a maintaining-circuit independent of the track relay 16; the armature 23 closes the circuit of the line indicator 24; the armature 26 prepares the circuit for the signal reverser 27 and the armature 7 connects the battery section 30 instead of the section 6 to the contact of the key 5. When the key 5 is depressed to show that the signal has been received, current from the section 30 rings the bell 11 and operates the indicator 12. At the same time the signal at B is lowered. When the train enters the first portion of the track, the relay 8 is de-energized and its armatures drop; the dropping of the armature 26 causes the signal to return to danger, and the dropping of the armature 23 causes the indicator 24 to drop to show "train on line." The men then depress the pushes 32, 38 to release the mechanical supports of the indicator arms, and the arms then drop to show "line closed." A release key 21 is provided so that the circuit of the local track relay 8 may be broken at will. In a modification, the connections are described for single line working between two stations. Two small local track sections are arranged at each end of the track with local relays and indicators. Relays are provided to permit successive trains in the same direction.

Member 12 may be formed from a blank to provide a flat-faced projecting channel with integral flanges 12a for fixing to the pillar 11 by screws 13. As shown, a saycut 12c separates the upper portion of the channel which is shaped to form a cylindrical or tapered socket receiving the cranked upper end of the usual guide rod 20 on which the ra il 16 slides. In an alternative form the guide rod is straight and member 12 has an arm wit h a perforation through which the rod is passed in line with the perforation 16a in the rail. Member 14 is of angular section, the limb 14b limiting movement by contacting with the channel side. The hooked recess in member 14 may be of such depth that initial lifting of the cot side is necessary to allow release of the hook, and the limb 14b may have an outwardlybent finger-piece. The stud may be secured to an angle-piece 15 attached to the rail 16 by screws 19 and with an aperture 18b registering with aperture 16a.

Filed: 1921-02-03
Abstract: 179,311. Watson, G. W. Feb. 3, 1921. Integrating; roller - andsheet recording-apparatus. -The integral of one quan. tity with respect to another, such as pressure with respect to distance, is measured by a pump driven proportionately with the distance, the output being controlled according to the variations of the pressure, with a meter for measuring the output. In the form described, a piston 23 is moved through a distance proportional to the pressure against the action of a spring 26 and effects through a spindle 25 and link 55 a tilt of a pivoted cam-plate 54. A plug 50, caused to rotate so that its angular movement is proportional to the distance, has four plungers 52 in barrels 51 symmetrically spaced about the axis, which are pressed against the cam-plate by springs 53, each barrel communicating by ports in a port-plate 57 with corresponding barrels 58 in a second plug 59 revoluble about an axis 63, which drives a revolution-counter 66 through gear-wheels 64, 65. The plungers 61 of this plug bear against a second cam-plate 62 which may be inclined to any desired degree and then fixed. The inner ends of both sets of barrels and the passages between are filled with fluid so that the plug 59 and its plungers constitute an hydraulic motor energized by the output of the pump 50, and the angular movement of the spindle 63 is a measure of the work done. Pressure variations are recorded on a chart carried on a drum driven proportionately with the distance by a stylus moved through a lever mechanism by a crosshead 28 attached to the spindle 25. A time indication is made by a second stylus normally fixed, but deflected at regular time-intervals by an electromagnet, the circuit of which is periodically closed by clock-work.
