SU36614A1 - Automatic Glass Blowing Tube - Google Patents

Description

The proposed self-acting glass-blowing tube is intended for mechanically blowing glass products instead of unhygienic mouth blowing by the worker. In the proposed invention, for this purpose, a pump is used in which a rod with a double-sided conical tip passes through the channel of the tubular rod squeezed by a spiral spring and serves, on the one hand, to close the stem channel and, on the other, to inject the bore in the cylinder head to which is attached glass blow tube.

In FIG. 1 shows a longitudinal section of a self-acting glass flow tube; FIG. 2 is a section along the line AB in FIG. one; Fig, 3 is a longitudinal section of a variant of the wall pipe; FIG. 4 is a front view of the grip of the piston, and FIG. 5-schematic transverse section irrshn.

Cre; a; lagae glass-blowing sobbit of cylindrical tube 1, which communicates with a Gaussian tube 2, on which glass is used during operation (Fig. 1).

In the cylinder 1 there is a piston 3 with a tubular rod 4, through the channel of which the rod 5 passes through Jaco (102)

not nickname 6, intended for stocking either: Kanavia at 4, or notch 17 in the lid of the 18th tsilidra. Piston 3 A conical winding in, according to the company, corresponding to a thickening of the rod 7 On the other side of the pig 3, on the rod 4, there is a nut 9 with pins 10 on the side facing the piston. A spiral spring 11 is put on the rod 4, abutting with one end into the stem 12 of the rod, and the other into the cylinder cover 13, in which holes 16 are drilled for air passage. The end of the stem 4, which extends outside, is provided with a handle 14, and the end of the stem 5 protruding beyond the next one is pressed from it by a spring 15.

In the process of work tsa. the gas tube 2 dials the glass and the piston 3, the rod 4 by the handle 14, pulls back to the lid 13. The conical thickening 7 of the stem leaves the piston 3 until the pins stop 10 in the porsche and forms an annular gap through which air penetrates under the piston, and the pins 10 Do not allow the nut to close the end slot. G releasing the handle 14, the rod 4, under the action of the spring 11, advances to the cylinder cover 18 and, entering with a tapered thickening 7, into the recess 8

3, the latter is pulled away after itself, as a result of which the air enters the gas tube 2. If it is necessary to stop / reduce the blast, then press on the eraser. j1. en 5, with its head 6 moving oi of the rod 4, and closing the recess 17, with the compressed air rushing into the cylinder channel of the rod 4 and out of it

FIG. 3-5 pictures of a self-acting glass-blowing pipe, in which a pump of the type sharpened in Yrimus is used.

In cylinder 1; closed by a lid 13 with openings 16 for the passage of air n with tube 2 at the other end. The piston 3 is placed, moved by the mTokOM 4 by the handle 14. In the piston 3, which is hollow, there are guide rails 20 for the stem 4, (Fig. 5), forming inlets for air passage. The stem 4 has at the end the claws 21 of the piston 3, which is placed with a certain gap between the latter and the cover 19 fixed on the rod. The latter rests on the rod of the spiral spring 11, the other end of which rests against the cylinder cover 13.

When retracted by the handle 14 of the rod 4, the grippers 21 will be moved together.

with them and; brsh: she 3, Shirk 19 will squeeze withSpring 11; at the same time air will pass under the piston through openings. When releasing the handle 14, the cover 19 under the action of the spring 11 will close the holes of the piston and the air will drive through the tube 2 into the blown product.

During the return stroke of the piston, as already mentioned, air will pass through the holes under the piston and therefore the product to be blown will not be compressed by the pressure of atmospheric air.

The subject matter of the invention.

I A self-acting glass-blowing tube, characterized in that through the channel of the tubular rod 4 connected to the glass-blowing tube of the pump and pressed by the internal spring P, the rod 5 passed by the outer spring 15 beyond the handle, 14, is fitted at its other end with two-sided conical tip 6, which serves, on the one hand, for the transfer of the rod channel, and on the other, for plugging the recess 17. in the top cover 18.,.
