Description

The exchange of rail wands on the train, i.e. the transfer by the locomotive brigade to the station agent of the rod used on the previous leg, and the simultaneous transfer to the steam train for the next stage, in the absence of special devices for this purpose, is connected, on the one hand, with the inevitable the delay of trains, and, on the other hand, some danger for railway agents directly involved in the production of this exchange.

The proposed device is designed to exchange wands automatically, i.e., without direct participation of people in it, at a relatively high speed of the train and exclusively for the wands of a small sample and consists of two pick-up devices, one fixed on the steam locomotive, and the other on the mast between the main and adjacent station tracks;

In FIG. 1 is a diagram of the device; FIG. T, 2, 2, 3, 3 3, 4, 4, 5, 5, b, 6 are its various details. The locomotive apparatus consists of a metal fork-like bracket 1, hinged at one end on the side wall of the tender and having sockets 22 for receiving and for

handed sticks, in which the wands occupy the same position in the projection and shown in the diagram by dashed line 17. Slot A is designed to receive a wand transmitted by the station apparatus, and Slot B - for a wand handed over by a steam locomotive, implying movement of the locomotive from 5 to L. The mouths of the sockets are provided with springs 23, which serve to keep the sticks from falling out of them. Between the upper and lower ribs of the apparatus, there is a funnel-shaped part 2, facing with its wide opening in the direction of movement of the locomotive, in the side wall of which facing the free end of the apparatus, there is a through slot for gripping the projection 19 of the head section of the track apparatus, and inclined knives 3, 3 for aligning the protrusion 19 in the vertical direction (Fig. 2-2). Part 2 serves to precisely position the axes of the transmitted wands in one vertical platform by moving the head 5 to one side or the other, as well as lowering or raising it with the protrusion 19 as it moves in the blades 3, 3.

The track apparatus consists of the following main parts: a bracket (FIG. 3) fixed on the fixed mast, a movable head 5 (FIG. 4-4); devices for automatically bringing the apparatus into an inclined position on the transfer of rods (Fig. bb).

The arm of the track apparatus (Fig. 3) consists of a steel ruler b constituting the base of the bracket, which has the shape of a triangle, which, at its apex, passes into a straight flat ruler and is attached to the fixed mast on hinges 18. On the straight part of the ruler there is a notch 29 in which a helical spring is placed, which adjusts the position of the head 5. The normal position of the head, as well as the position of the fixture mounted on the ruler for automatically bringing the device into an inclined position, is shown in FIG. 3 dotted line. The bottom plate 14, attached to the main ruler of the bracket b by the hinge 32, carries at the end a glass 7 serving as a room and support for the steel spring supporting the ruler b. The position of the spring relative to the ruler b is fixed by a plug 30, screwed into the ruler, and a rod 31 suspended from the stopper with a thickening at the end limits the play of the spring within the proper limits. This spring allows the head 5, / when pressing the protrusion 19 of the knives 3 of the locomotive apparatus, to adopt a position that exactly corresponds to the height of the locomotive apparatus. The plate 14 has a hinge 33 connecting the ruler to the tubular strut 15, and an eye 13, connected to the eye 12 at the upper end of the strut using a helical spring, limiting the scope of the bracket when lowering it at the moment after the exchange of wands.

The head of the track apparatus (Fig. 4) has the form of a box and consists of three main parts: the upper and lower cheeks and the protrusion 19 clamped between them; both the upper and lower cheeks have jacks 22 for rods with springs 23, like the same jacks in the locomotive apparatus and one guide channel 35 for buffers 37. The rubber tips of the buffers 37 are in the middle position of the latter, they stand behind the outline of the jacks and therefore when the tab to jack A of the rod to be transferred to the locomotive, both buffers are shifted

toward the nest S by the same amount. The distances between the AN jacks in the b of both machines, locomotive and track, are exactly the same. Therefore, at that moment when the rod in the nest ti of the locomotive apparatus is already touching the tips of the buffers in the nest & the track apparatus, between the nest A of the locomotive apparatus and the rod in the corresponding socket A of the track apparatus there still remains some definite distance and, therefore, by the time the locomotive apparatus of this baton is captured, it already has time to receive an elastic impact from the buffers, which tells it the speed corresponding to the speed of the locomotive which ensures the smooth transfer of the wand. The course of the buffers, in order to prevent them from falling out of the apparatus, is limited by screws with 38 screws screwed into the channel wall and the ends entering the corresponding cuts in the wall of buffers.

The protrusion 19 of the head, sandwiched between the cheeks by its bolts 39, protrudes from the head in the form of a frame, at one extreme outer corner of which there is a tide of elliptical shape protruding from its horizontal edge. With help . this tide, when it passes through the funnel-shaped part 2 of the locomotive apparatus, the head 5 moves in one direction or the other along the bracket 6, depending on the degree of inaccuracy of the relative position of both apparatuses in the horizontal direction, until the exact axes of the sockets and the rods of both apparatuses coincide (Fig 2). After the exchange, the head automatically returns to its middle position with the help of a coil spring located inside the head in the recess 29 (Fig. 3) of the ruler b.

A device for automatically bringing the track apparatus to an inclined position by transferring the rods consists of a steel shaft 21 fixed in bearings 41 inside the head 5 to its upper cheek and connected to the upper buffer by means of a bolt passing through a through hole in the buffer body, and cranks 40, 40 with protruding bolt holes. The protruding end of the shaft 5 has

square cross section and freely slides in the coupling. For the possibility of assembling the fixture in the channel walls of the upper buffer, there are corresponding cuts covered with rigid covers 42 (Fig. 5). The housing 46 is fixed on the bracket 6. The coupling 47 of the shaft 21 has a square cross section inside and is kept from the longitudinal movement by a round nut 48. On the outer surface of the coupling there are 4 knuckles 49, in the hollows between which the corresponding knuckles 49 have another coupling 50, freely slidable in the housing 46. and imbibely mounted on the end of the tubular rod 20. The spiral spring 9 is loosely mounted on the rod 20 and rests one end on the coupling 50, and the other on the square 51 fixedly mounted on the bracket 6. when the rod 20 is ready, it is retracted in the direction of the spring, whereby the spring is compressed accordingly, and the upper buffer is simultaneously shifted toward the socket B, as a result of which the rod 21 rotates and with it the coupling 47, with which the fists become opposite to those of the coupling 50.

The apparatus is prepared for the upcoming exchange of wands, having previously inserted the handed wand into the corresponding slot, by turning it into the working position and securing the apparatus in this position. The nest is the second, counting on the movement of the train and open to the side, the opposite of movement. The very first socket, opened in the movement bar, remains free to receive the rod from the station.

At the moment when the locomotive apparatus approaches the track knives 3, 3 of the first one, mounted on the similarity of the opened scissors, the protrusion 19 is grasped integral with the head 5 of the track apparatus, which in the case of the horizontal axis of the latter does not coincide with the axis of the locomotive apparatus (line Vni of the scheme) , respectively, raises or lowers the head of the track apparatus to the proper coincidence of the Axes of both vehicles. At the next moment, the protrusion 19 enters the funnel-shaped part 2 of the locomotive apparatus and guides it with the head 5 in one direction or the other in the horizontal direction until the geometrical axes of the sockets and the wands of the two apparatuses sitting in them (line V of the circuit) coincide. At the moment of the passage of the protrusion 19 through the funnel-shaped part 2, by which moment the tail and the axes of the wands of the two apparatuses coincide, the wand being handed in by the locomotive enters the receiving slot of the station apparatus and the wand simultaneously transmitted to the station is captured by the receiving engine. In doing so, the rod handed over by a locomotive, having a living force according to the locomotive's speed, hits the rubber tips of horizontal buffers 37, which are somewhat prominent from the body of the head 5 only by their outlines of the receiving socket. These buffers slide freely in the corresponding cylindrical channels in the body of the head and with their other ends with rubber tips resting against the rod inserted into another nest of the same apparatus to be transferred to the engine. As a result, according to the law of elastic impact, the living force of a baton handed over by a locomotive is transmitted directly to the baton to be transferred to the locomotive, without any harmful effect on the apparatus itself, and with only a loss of compression of the springs 23 in the mouths of the jacks from falling out of the nests.

After the exchange of the rods, the locomotive rotates to the tender, the traveling apparatus, which is partly outstanding, as shown in the diagram, beyond the preset limit for the posts at the stations (line VI), is immediately removed beyond this limit to avoid accidents with persons traveling in the train. This process is accomplished as follows: the upper buffer, when it is moved under the action of the impact of a rod, through its core and earrings 40 (figure 5) passed through its body, turns a steel shaft 21 reinforced at one angle in bearings in the head of the apparatus and freely the other end of the square seed sliding in the coupling 47, freely rotating, but not having a longitudinal movement, and provided with fists arranged crosswise to the cross, against which the corresponding fists rest at the end of the said tr The bar 20 is fixed at the other end. When the rod rotates at a known angle at the moment of exchange of the wands, the clutch fists turn against the hollows between the fists of the rod 20. At the same time, under the action of the spring 9, the rod 20 together with the stopper moves somewhat to the side the lock, as a result of which, hanging on the stoppers, the ha is losing its support, which is why the entire apparatus under the action of its own weight is released, turning around the hinge 18, taking a position, as shown by the dotted line in the diagram. In order to avoid a shock when the apparatus is lowered, the lugs 12 and 13 on the strap 14 are connected to each other by a spiral spring, which, due to the lowering of the apparatus, due to the increase in the distance between its reinforcement points, limits the span of the apparatus and smoothly stops it in the proper position.
