Description

The present invention, relating to the machine for the production and processing of sleepers, is based on the combined use of a conventional sawmill frame and a tool for planing oval parts of the surface of the sleepers.

In the schematic drawing of FIG. 1 is a side view of the machine; FIG. 2, top view of the machine.

The machine is arranged as follows: on a frame consisting of longitudinal bars a, interconnected by crossbars b, pillars c and braces g, a regular type sawing frame is fixed, which is intended for sawing the sleeper into sleepers. The drive pulley to the flange is wedged on the crankshaft 3 lying in the bearings and driving the connecting rods connected to the frame, in which the saw blades are fastened; the frame has the ability to move up and down in rails attached with brackets to the lower bars of the bed and with the help of plates for posts and racks mounted on the upper bars of the bed; on the shaft p connected by a flexible gear with the shaft 3, eccentrics 3 are fixed, which with the help of rods 4 act on ratchet wheels mounted on the same shaft with the rollers c; Above the latter are located the rollers movable in the posts φ, which are under the action of the springs y. Rollers with and with serve for giving of skin when sawing. The device, designed for planing oval parts of the sleepers surface, consists of a bed hardened on the top longitudinal bars and on which two rows of conventional planing cartridges are fixed one above the other, of which the cartridges of the top row are fastened with screws ( according to the size of the sleeper to be machined. The lower and upper row patrons are rotated by pulleys connected by a flexible gear to the pulleys e and "O", the first of which are stuck on the intermediate shaft l, and the second on the intermediate shaft "1." Both intermediate shafts are driven into rotation by means of pulleys attached to them, connected by flexible gears in and "with pulleys l mounted on the crankshaft 3. For supplying gantry sleepers coming out from under the saws, the clamping carriage S is movable by means of a rack and pinion gearing consisting of fixedly fixed rails, which are attached to gears mounted on the carriage and rotated by hand by means of handles 5. Feed

during gouging the sleepers are produced by pairs of rollers in two extreme pairs; the lower roller receives rotation from the axis of the planer cartridge nearest to it using an eccentric 3, acting by means of a rod 1 on the ratchet wheel 2, stuck on the axis of the roller.

The operation of the machine described is that the sleepers resulting from sawing with saws o are placed two pieces on the chucking cart h, and are fed into a device for planing oval parts, where they get the final shape.

The subject of the patent.

A machine for the manufacture and processing of sleepers, characterized by the cumulative use of: a) a sawing frame of a conventional device for sawing felts (tyulek) into sleepers, b) clamping, for sleepers coming out of the sawing frame, manually moved by rack and pinion engagement, c) fitting for planing the oval parts of the surface of the sleepers emerging from under the saws, representing two rows of conventional planing cartridges, of which the upper row is equipped with the same mechanisms for mounting the cartridges according to the size of machining aemyh sleepers and g) means for feeding sleepers to planing tools, consisting of several pairs of rollers of conventional Oy, in which there are pairs of extreme lower roller receives the rotation from the nearest planer fitted on the eccentric axis of the cartridge 3 by means of the ratchet mechanism 1-2.
