SU26840A1 - A count of the number of wagons entering a stretch of track - Google Patents

Description

The invention relates to counters for the number of wagons entering a particular section of the track, using counting disks driven from those located on the track and interacting with the cart of pedals.

The proposed counter for the purpose of preventing abuse by means of prolonged pressure on the pedals is equipped with a device which, after such pressing, takes the counter out of action, with a simultaneous indication of this on the control hours.

In FIG. 1 depicts a vertical section of the counter of the number of wagons entering at any part of the route; FIG. 2 - view from above; FIG. 3 is a side view of it; . 4-view it from the other side; FIG. 5 - clutch gear with the disk; FIG. b and 7 view of pedals in two projections; FIG. 8 type of control clock on the side; FIG. 9-front view.

On frame 1 and 2 in bearings there is a shaft 3, which is connected with pedals 4, transmitting rotation to the shaft from pressing the pedals. Pedals 4 (Figs. B and 7) are mounted in recesses 31 of the outside part of a bridge or road on axles 32 and, by means of a shaft transmitting rotation 33, are connected by means of one or another device to shaft 3. Pedals 4 are held in their upper position

counterbalances 34. On the shaft 3, two countable disks 5 and 6 are free;

which the first of them marked the numbers of tens, and the second figures of units. The rotation of these discs comes from the shaft 3 by means of a lever 7 connected at one end by a hinge

with crank 9 of shaft 3, and the other end of disc 6 entering into ratchet. The lever is constantly pressed by spring stop 8 towards disk of ratchet b and guide arc 10. Disk 11 is freely mounted on shaft 3, which is integral sleeve 12 and. ratchet 13. On the sleeve is fixed by the dead end of the winding spiral spring 14, the other end of which is fixed in the lugs 15 of the frame 1. In the established state, the spring is held by a lug 16 placed on the disk 11, which rests on the cheek 17, fixed on the axis in the crank 9. a At the other end, sliding along the guide arc 18.

A free gear 19 is mounted on the shaft 3, connected to the worm 20 on one side, and on the other, a ratchet dog 40 fastened to it, with a ratchet 13 dira 11; The dog 40, during the spring plant, jumps over the ratchet, and when the spring develops, the gear 19 rotates together with the storage and disk 11 to one side. A worm to 20 by means of a gear 21 engages with a massive regulator 22 of the spring spin-up speed 14. The arrow 24 of the control clock 23 (Fig. 8, 9) rotates the gear 25 connected to the roller 26 with needles, which, when the gear is rotated the tape 7L, since the needles enter the slots made in the paper, the dimensions corresponding to the size of the needles and the distance between them around the circumference of the roller 26. The elastic roller 27 is an annular slot for the needles, and presses the ribbon 27 to the roller 26. This whole mechanism is attached to the clock with the help of new framework 28, 29, 30.

The wheels of the crew, when moving on the roadway of a bridge or road in the place where the meter is installed, press the pedals 4, which rotate the shaft 33 and the associated shaft 3 and with the help of the lever 7 rotate the counting disk 6 by one division. In this case, the lever passes approximately to the protrusion 35 on the arc 10. Further turning of the 3-count shaft will not occur, since the protrusion 35 on the arc 10 will lift the lever 7 and thereby bring the latter out of its engagement with the ratchet disc 6.

The disk 5 can be connected to the disk 6: using the latch 36 and the arc 38 and turns one division with a full turn of the disk 6 with the unit numbers, which is reached by the spring 36, constantly pressed to the spring 38 by the arc. The left and right parts of the inner surface of the arc 38 are eccentric, which allows the latch 36 only once, with a full turn of the disk 6, to hook the disk 5 over the tooth 37 and turn it one-tenth of a turn.

When the shaft 3 of the latch 17 rotates, it moves away from the protrusion 16 of the disk 11, but the spring 14 tends to loosen and rotates the disk 11 and its protrusion 16, which follows the latch 17. If the mechanism of the latch 17 is working properly, the protrusion 16 should be delayed when sliding it to the protrusion 26 along the arc 18. With the disk 11 the gear 19 also rotates, which with the help of the screw 20 and the controller 22 creates a smooth unwinding of the spring 14.

The time required for the spring to unwind and the passage of the protrusion 16 of the disk 11 and of the latch 17 to the protrusion 26 on the arc 18 should be approximately equal to the entire time of the pedal being pressed; until the ledge 26 of the latch 17 moves along the arc 18, parallel to itself, and when the end hits the ledge 26, its right end rises, and the left one goes down, and will not be in the way of the movement of the protrusion 16, but because of the reverse movement, if the specified time does not match , the heck 17 will not capture the protrusion 16 and will not bring it back, and the protrusion 16 will pass further relative to the protrusion 26 and stop, in one way or another, the progress of the control hours 23. With the reverse movement of the heck 17, the disk 11 will not turn the springs 14 and most disrupt the proper operation of all o The mechanism and the stopping time of the counter will be recorded on the paper tape 27.

The subject matter of the invention.

Claims (4)

1. A counter for the number of wagons entering a particular section of the track, using counting discs set in motion from the pedals located on the track and interacting with the cart, characterized in that, in order to prevent abuse by prolonged pedal application, the meter is equipped with , withdrawing it from the action after such a click with a simultaneous mark on the control clock. 2. The form of the counter according to claim 1, characterized in that the device, removing it from the action, consists of a disk 11, freely mounted on the shaft 3, rotated from the track pedal, under the influence of the clockwork spring 14 and held from rotation of the protrusion 16 on it, resting on the whole of the 17, able to slide along the guide arc 18 and, in turn, held by the stop 8 fixed to the shaft, what is the guide arc 18 is provided with a protrusion 26 that retracts, in the case of excessive duration of pressing track pedal now oldu protrusion 17 from the path of movement 16, thereby not allowing spring 14 when reversing the shaft 3. 3. With a counter in pp. 1 and 2, the application of the regulator of the rate of unwinding of the spring 14, connected by a worm gear to the gear 19, which is loosely mounted on the shaft 3, engages, with the help of a ratchet, with the disk 11. 4. With the counter in pp. 1 and 2, the application of the control clock 23, stopping when the counter is abused, the hand of which 24 hours is coupled with the gear 25, which serves to move the paper tape, at which the time for the estimator to stop is recorded.
