SU23248A1 - Electric Shuttle Self-Stops for Belt Looms - Google Patents

Description

The proposed electric self-stopping is intended to stop the machine and indicate the breakage or outcome of the thread in the shuttle looms of various purposes (belt, rubber, wick, etc.). The invention eliminates the need to observe the spools, i.e. gives the weaver the opportunity to do other work at the same time, for example, to descend the foundations on a running machine or work on two or more machines.

In FIG. 1 and 2 depict the types of the shuttle, respectively, from above and front; FIG. 3 and 3 - detail of the l-shaped rod; FIG. 4 - side cut through the sleeve;

ig. 5 - diagram of the action switch L-shaped rod).

A copper bushing B is inserted into the handle of the shuttle of the weaving loom (Figs. 1 and 2). A piece / 4 of thin copper wire is inserted into it, consisting of an L-shaped rod with a ring at the end (Fig. 3). A thread is passed through ring A (Figure 4). Thus, the thread passes from the spool in the shuttle through the ring of the L-shaped rod (closure) A, through the handle, provided with an eye G, and goes out into the tape. In this case, if the thread is in the system, then the contactor A is raised. If the threads in the system do not turn out, whether due to a breakage or an outcome, then

the contactor A is lowered onto the plate D (Fig. 5) and closes the electrical circuit of the detector with a bell, a relay and contact springs located on the batana. Thus, a call and a stop of the Machine will be received simultaneously. The shuttle is in contact with the contact springs located on the baton by means of stops B; the latter are connected respectively with the plate D and with the contactor A with the wires T, which are laid in the corresponding kerf in wood and then glued with glue or shellac.

The electrical circuit allows the connection of any number of cells - shuttles, with one automatic device and one alarm device.

The subject matter of the invention.

Electric shuttle self-stopping for belt weaving machines, characterized by the use of a meta-metallic L-shaped rod A, pivoted at one end in sleeve B and fitted with a ring at the other end for passing the weft thread going to the eye, which ring is designed to break the thread to close the electrical circuit T by lowering onto a plate.
