Title: Apparatus for automatically operating barriers for level crossings
IPC: B61L29/20
Filed: 1925-08-05
Abstract: 253,743. Ogawa, Y. Aug. 5, 1925. Operating and controlling gates by treadles and the like, and by weights and chain and cord arrangements; signalling operations of gates.-The gates of a a single line track 1 are operated by a pair of treadles 3 arranged some distance to the front and rear of the railway-crossway respectively, and by an intermediate treadle 4, and the arrangement is such that the operative mechanism closes the barriers when the first treadle 3 is depressed by the trains and opens it when the treadle 4 is depressed, the last treadle 3 acting to re-set the operative mechanism without further movement of the barriers. The treadles 1 are for the operation of an alarm bell. The barriers 8 are connected by cords 29 to a plate 13 pivotally mounted on one side of a bracket 6 carried by a post 5. This plate is prevented from rising under the action of the weighted barrier by a weighted lever 14, which engages a spur 15 projecting through the plate 13 and forming part of a link 16 pivotally connected, and controlled by an inverted U-shaped member 17. The member 17 is pivotally mounted on the plate 13 and it is controlled in turn by the blades 12<a>, 12<b> on a spindle 12, mounted between the curved members 11 secured to the box plate 6. The spindle 12 carries also a Z-shaped member 23, with which engages the arm 19<b> of a pivotally-mounted weight 19. Another arm, 19<a>, of the member 19 projects across the slot 11<a> and into the path of movement of the end 10<b> of the weighted lever 10<a>. This lever has a pulley 9 with a cable connection 20 with treadles 3. The treadle 4 is connected with the weighted bell-crank lever 14. The device operates as follows :-A train approaching the carriers depresses first the treadle 2 to sound the alarm bell, and then depresses the treadle 3 to rotate the pulley 9 through the rope 20. The end 10<b> of the rod 10<a> is thus moved in the slot of the member 11, engages the blade 12b, and causes the blade 12<a> to move the U-shaped membet 17 and the projection 15 to be depressed into the plate 13, as shown in Fig. 6<b>. The plate 13 is then freed from the weight 14, and is raised under the weight of the barriers, which move down into the closed position. As soon as the train has passed over the treadle 3 the pull on the rope 20 is released and the rod 10<a> returns to its raised position. When the treadle 4 is depressed the pull on the rope 21 raises the bellcrank 14, which rides over the projection 15 and then engages it to lower the plate 13 and open the barriers when the treadle 4 is released. The depression of the second treadle 3, positioned beyond the barriers, causes the boss 12 to turn as before, but in this case it is the forked ended blade 12<b> which moves against the member 17. The member 17 is not moved and the plate 13 is not operated, and the boss 12 returns to its position with the blade 12a in the operative position for the closing and opening movement of the barriers by a subsequent operation of the treadles by an approaching train.

Abstract: 720,124. Electric petrol consumption indicators. CARDELLI, M. Sept. 5, 1952 [Aug. 11, 1952], No. 20125/52. Class 40 (1) [Also in Group XIX] A device for measuring fuel consumption in gallons per mile comprises a flowmeter measuring gallons per hour and a tachogenerator measuring miles per hour, the individual signals being fed to a device which divides the first by the second by a mechanical divisor. The flowmeter comprises a magnetic core located in the flow path of the fuel so that its position is dependent on the magnitude of the flow. The core is in the magnetic circuit of a transformer whose primary is fed with a constant voltage A.C. and whose secondary produces a voltage proportional to the fluid flow, e.g. gallons per hour. The speedometer comprises a normal tacho-generator attached by a flexible coupling' to the motor to give an output voltage proportional to the speed of the motor, e.g. miles per hour. The divisor (Figs. 1, 7) comprises two perpendicular, spring-loaded electromagnets fed with the voltages from the flowmeter and speedometer and coupled via a constrained parallelogram whereby the ratio of the two voltages is indicated by a pointer. The voltage from the flowmeter energizes a solenoid g to control the position of a spring-loaded armature d, and the voltage from the speedometer energizes a solenoid f to control the position of a second perpendicular spring-loaded armature e. The armatures d, e are attached to the ends C, A respectively of a bar h comprising one side of a parallelogram whose diagonals are hinged together at the centres V<SP>4</SP>. One corner a<SP>4</SP> of the parallelogram is pinned to the instrument frame, and the other corners may slide in slots in the bar h and in a second bar extended to form a toothed sector j. It is shown that the angular movement of the toothed sector is proportional to the ratio of the movements of the two armatures d, e and is transmitted via pinion wheels n, l to a pointer o.
