Description

The proposed cuttings for a weaving machine with a lead to it has the following advantages against the existing low cutting: 1) ease of manufacture; 2) it eliminates the need for additional parts of the Platt machine, necessary for iron removal of the existing structure; 3) thanks to a lighter job, less cut out and a protrusion in the slot people, nightgowns; And by changing the shape of the leash, guiding the running belt to a full one is guaranteed, and 5) all taken together. Reduces the cost of operating the Platt loom.

The drawing shows the front view of the machine.

The proposed layoff for a weaving machine consists of a cast iron lever 1, a cast iron bracket, a square 8 and a cast iron lead 12. The upper end of the lever 1 ends with a handle, and the lower end is bent at an angle in the form of a process 2, at the end of which there is a hole 3; perpendicular to the plane of the lever 1, in place of its bend, is a finger L of circular cross section.

At a distance of about 300 mm from the lower end of the lever 1, a gon b is screwed through the hole in it 5 with a bolt. Cast iron bracket, square 8, its wide plane is screwed with a bolt 7 to the frame of the machine

into the oblong slot of the frame one vertical with the shuttle, so that the other part of the square 8 fits under the brake lever 13 without touching it.

A finger 4 of the lever 1 is inserted into the opening 9 at the free end of the square 8, the upper end of the latter is preliminarily held in the slot of the shuttle-holder, screwed to the frame. The finger 4 is secured with a linch pin 10, which holds the finger 4 from sliding out of the hole.

In the hole 3 of the process of the lever 1, the thread is bent over the end of the coil spring P and the other end of the spring is attached to the frame of the machine. The curved lead 12 is at one end put on the finger of the angle g, bolted to the lever 1 with a bolt 5, and the other on the slide with a belt fork.

When translating the drive belt from the idler pulley to the main one, simultaneously with the movement of the lever 1 along the slot of the shuttle, it changes its position and the lower end 2 of the lever 1, which, lifting, lifts the brake lever 13 on its face, the output flywheel from the brakes. The retraction of the cuttings is performed by means of a coil spring 11 and a load 14 suspended on the brake lever 13.

The subject of the patent.

Loom for a weaving machine, characterized by using a rigid starting lever 1, pivoting on a finger 4 in a fixed bracket 8 and having a right angle bent

end 2, in order to raise the brake lever 13 and then turn off the brake during operation of the machine, which lever 1 is equipped with a helical spring P, in order to activate the brake when transferring the belt from the worker to the idler pulley.
