SU12402A1 - Device for indicating bus, tram and railway wagon stops - Google Patents

Description

In the proposed device, in which it is possible to indicate the following tram from the last tram stop, a nonstop elevation of the plates with the names of the stops is made using two fingers fixed on the screws to be rotated.

The drawing shows an axonometric, projection of the described device, which consists of box 1, shown on the package by a dotted line, inside which there are two pairs. The vlannt 2-2 are located with their own supports fixed nuts 3-3. At one end of the shaft of the screws are mounted 1; cylindrical gears 4-4, which bind both screws; on the other end, fingers 5-5 are rigidly fixed on them. Above the rods 2-2 there is a series of p-tastin 6-6 of transparent material arranged in the form of a foot, on which the names of the stops are inscribed. In addition to the cylindrical gears mounted on the screw rods, one of them is fitted with a bevel gear 12, which also engages with the bevel gear 11, which sits on the drive screw 10, which in turn is connected to the repeaters (with a control device) intended for checking removed the entire instrument.

The repeater consists of a board (table) 8 with stop names inscribed in the appropriate order, with a frame 9 moving along IT, in the slot of which only one stop should be seen.

Thus, during the rotation of the screw 10, the screws 2-2 are also rotated by means of the above-mentioned gears, which, rotating in the stationary nuts 8-3, are displaced axially, which will cause the plates 6-6 and lift to the height of the window 7, which is at 1. At the same time, the frame 9 of the control device with the help of vipt 10 moves the appropriate amount on the board 8 and the device will work correctly if the names of the stops shown in window 7 and in the slot of the frame 9 are the same .

The subject of the patent.

1. A device for indicating stops of buses, tram cars and railroad cars, characterized by the use of two parallel 4-4 screws 2--2 located in the box 1–2 with gear wheels 3–4 screws 3–5 fitted with fingers 5–5 that serve long consecutively placed in the box one after the other plates 6 with the inscriptions of the names of the stops and putting each against the slot 7 of the box, for which purpose the pitch of the screws is made equal to the distance between the plates.

2. Application for characterization in n. 1 repeater device consisting of frame 9, shift cus on board 8 with names of stops from the same screw 10, which rotates one of the vivts 2 to the name, corresponding to the name, visible through slot 7.
