SU28231A1 - Flap for freight car doors - Google Patents

Description

This invention relates to a door flap locked with a wedge.

In the proposed hinged latch of the doors of a freight car, and the purpose of protection against opening the gate when the car is thrusting, the cut-out in the horizontal shelf attached to the door is made with a protrusion under which the tab of the latch comes in when locked.

In FIG. 1 and 2 depict in two projections a type of gate valve; FIG. 3-vertical section of it.

The flap 1 (Fig. 1) has two tabs, which are included in the slot of sample -2. Each eyelet on the left side has a cutout A, forming a protrusion or tooth S, and an opening B for hanging a lock or seal. The latch is attached to the door with a conventional G bolt around which it revolves. In addition, due to the skewness of the spider (fig. 2) and the recess E, into which the bolt head falls, the valve can be retracted to the position indicated in fig. 2 dotted line. Breakdown 2 is made of angular iron and the right edge of the vertical flange is welded to the mock square of the car. In the vertical shelf is made, the hole G. (Fig. 3), coinciding with the hole -B

eyelet latch and employee for hanging the lock or seal. A horizontal shelf has a notch 3, which in its front part corresponds to the size of the entire width of the ear of the valve, and in the rear part forms a protrusion K (Fig. 2). The hole of the horizontal flange has a rectangular shape and such dimensions that bolt 3 freely passes through it, which is an automatic lock for the valve. It is made from sheet iron by bending it in half; E of the upper part, its width corresponds to the hole I, and B of the lower part, it is narrowed so that, being raised up and retracted to the position indicated in FIG. 3 by a dotted line, it does not interfere with the withdrawal of the eye of the valve from the probe. The upper ends of the bolt are divorced and bent close to the very bolt, forming a high head, and the lower ends are divorced so that the bolt cannot be pulled out of its place. In order to lock the car, it is necessary, closing the door, lift and take out the bolt 3 to the position shown in FIG. 3 by a dotted line, at which time the valve should be thrown over the sample so that the eyelet passes through the wide part of the hole, as indicated in FIG. 2 dotted line. Then, releasing the bolt 3, it is necessary to move the valve to the rear normal position, shown by a solid line (Fig. 2). Then the tooth B of the gate valve fits under the protrusion K of the sample and does not allow the valve to rise, and the needle 3, the slip plane of the plane L (fig. 3), will automatically lower down and become locked in position, at which the valve will be locked and then on the hole eyelet and breakdown of the lock or seal. When the car is unlocked, the seal or lock is removed, the bolt 3 is raised to failure, the valve together with the bolt is retracted, the valve is lifted from the breakdown and tilted to the right.

The subject matter of the invention.

A flap for doors of freight cars using a locking wedge, characterized in that, in order to protect the gate from opening during shocks of the car, cut-out 3 (Fig. 2) in the horizontal shelf attached to the door of probe 2 (Fig. 2 and 3) is made with the protrusion M, under which the tooth B of the eye appears when constipated. In gate valves 1.
