PATENT OFFICE.

The present invention relates to a device for feeding the pile thread bobbins to the fabric of large-width carpet looms. In the previously known devices is a single carrier for the pile threads across the entire width of the chair arranged extending coil frame, which is moved according to the work process. When making very wide carpets, it was now possible to move the Frame and the dense, uniform feed and position of the threads with respect to the fabric due to the large frame length and the resulting sagging of the frame. The present Invention is intended to remedy this deficiency; it is according to the same instead of a single one very long frame a number of short frames of normal length in a row next to one another arranged each other, which carry the pile thread bobbins and through in corresponding Number of conveyor chains arranged in pairs, holding the frames at the ends, in precisely measured, steady, step-by-step movement.

In the accompanying drawings, the subject matter of the invention is in one embodiment shown, namely Fig. 1 shows the loom in its entirety in the front view. Figure 2 is a vertical section on lines 3-3 of Figure 1. Figures 3 and 4 show the frame movement mechanism in side and front view. Fig. 5 shows the mechanism in the position of reversal of motion.

In the machine drawn, the general arrangement of the more important parts is made in the usual manner. It denotes: A the frame of the loom, B the breast beam, B ¹ the table for Webstück, B ² the Waarenbaum, C the Schützenbahn, -D the shafts, E is the main drive axle, F on the transverse shaft f swingable loading, the movement of in the usual way through the intermediary of the seated on the shaft e, casters f ² acting extender wheels / ¹ and the Armey ^3/4 takes place.

The working method of the drawn chair in the production of velvet fabrics is greater Width (moquette carpets) is conveniently the following:

One row of each of the frames g ⁵ , which are arranged in groups and carry the bobbins g ^a with the pile threads and which are held and moved by the warps G , are first brought into the area of the base fabric or the base warp by the step-by-step movement of these warps (Fig. 2). The frames are then detached from the chains by appropriately moved driver arms g ⁿ , in that these arms push back the resilient pawls that hold the frames on the chains and reach through the latter. The frames themselves are received by the arms h of a transmission mechanism which, lowering themselves, move the frame so far down that it comes into the area of the basic chain. In this position of the frame, the thread ends of the bobbins are grasped by clips which stand up through the chain and take care of the insertion and tying in of the pile threads in a suitable manner.

The special device of the device for feeding the pile threads to the fabric BEZW. to move the reel frame is as follows: The chains G (Fig. i) carrying the reel frame are arranged in pairs, namely three such pairs of endless chains are present, which receive their drive by the sprockets g on the transverse shaft g ¹ and on top of rollers g ² , are guided below on arched pieces g * seated on girders g ^s (Fig. 2). The frames carrying the coils are arranged in rows and are releasably connected to the chains G. In the present embodiment there are three such frames in a row, and the rows are separated from one another by a distance corresponding to the magnitude of the switching movement of the chain. Each frame consists of a cross rail g ⁵ on which a pair of side arms and a pair of curved rear arms are arranged. The side arms carry the spindles of the bobbins g ^s , so that several bobbins, three in the present embodiment, with each other respectively. lie with their axes in a straight line. The curved arms extend almost halfway around the ends of the bobbins, and are provided with projections at their inner or free ends which engage the open links of the chain G. Furthermore, pawls which are under spring action are arranged in a known manner, which hold the frames releasably in their respective position by engaging around the chains. On the cross rail g ⁵ sits a thread holder g °, which has the task of dividing the threads into tufts and holding them in the position in which they are gripped by the clips or tongs. The gradual movement of the frame respectively. The chain is driven by a switching wheel O, which sits on the lower rotating shaft g ¹ carrying the sprockets g , the pawl o ^{1 of which is located} on the turntable 0, which rotates with interruptions and after each rotation again by the spring o ^{2 is turned back} to the starting position. The turntable 0, whose movement by the pawl on the ratchet wheel and thus on the shaft g ^! is transmitted, is driven by a lever P, on which a sector ρ sits, from which the chain p ^{1 is placed} over the rim of the disk 0. The lever P is supported by a lifting disc p ⁷ through the intermediary of the arm p ² , the rod p ³ , the lever j? ⁴ and the roller p ⁵ moved, so that the turntable and thus the shaft g ¹ and the chains G are moved in the manner required for the regular pattern formation. On the other side of the ratchet wheel O is also loosely seated a second turntable Q carrying the pawl g ² , which is in positive connection with the sector ρ of the lever P durgh the chain q and which is turned back by the spring q ¹ after each switching movement . The arrangement of the pawl q ² is such that, when it is in engagement, the ratchet wheel, respectively. the shaft g ¹ and thus the chains G are moved in the direction opposite to the usual direction, whereby the pattern is generated in the reverse order. The arrangement of the coil frame in several parts, and that is only the present invention, the loom carpets of any width can by means of simple and ^r in intended purposes w ay be woven. As mentioned earlier, it has been very difficult to make wide fabrics of this type; the difficulty lay, among other things, in the fact that it is necessary that the bobbin frames must be kept in a regular horizontal position and not spring out of their direction. Rather, you must present the ends of the pile threads in a uniform and uniform row to the tools that produce the pile. At the same time, the frames themselves must not be too heavy so that they can be conveniently handled by the workers whose job it is to remove the empty bobbins from the frame and put full bobbins back on. The individual coil frames themselves can again be made from several parts, each of which carries his own coil, and which can be so assembled that they are a uniform frame of the desired length for practical use form. Godfather nt-A ν saying:
Carpet loom for the production of carpets of great width, characterized in that instead of a single long spool frame a number of frames are arranged in a row and accordingly a larger number of paired conveyor chains over the entire length of the chair, for the purpose of safe guidance and the To enable normal wide frames to be used and to avoid sagging, etc. 1 sheet of drawings.
