VALENTIN NIEDERWERFER, 0F BURKHARDTSDORF, GERMANY, ASSIGNOR TO THE FIRM 0F FIEDLER & 00., G. M. B. I-L, OF BUBKHARDTSDORF, GERMANY.
DEVICE FOR MAKING THE CUTTING-LISTS OF SLIT-U]? FABRICS.
Original application filed April 21, 1914, Serial No. 833,492.
Serial No. 35,183.
To all whom it may concern:
Be it known that I, VALENTIN NIEDER- wnnrnn, a subject of the German Emperor, and resident of Burkhardtsdorf, Germany, have invented certain new and useful Improvements in Devices for Making the CuttingLists of Slit-Up Fabrics, of which the following is a specification.
This invention relates to an improved device for making the cutting lists of slit-up fabrics, the present application being a division of my prior application Ser. No. 833,492 filed April 21, 1914. Devices which serve for the same purpose, are already known. The novelty of the improved device consists in the arrangement of laterally movable curved needles beside the known up and down movable eye-needles. By these curved eyeneedles, simple moving mechanisms are created and very fine and tight warps, such as for instance for umbrella fabrics, can be securely guided without friction.
In the accompanying drawing:
Figure 1 is an elevation of the device fitted with curved eye-needles showing said needles in closed position.
Fig. 2 is a side view of Fig. 1.
Fig. 3 is an elevation of the device fitted with eye-needles showing said needles in open position.
Fig. 4 represents the laying of the warps.
The eye- needles 25 and 26 are arranged on levers having a scissorlike movement, while one slide 4 is guided so as to move up and down. Thereby, the operation is as follows Upon slide 4 being raised by a pull on cord 5, the pin 11 arranged on a movable pawl strikes upon aprism 6 and turns the same for a quarter of a turn. By this move ment, the tappet 7 arranged on the same axle as prism 6 presses the levers 27 and 28 asunder, and thereby, of the superposed levers 29 and 30, one moves to the right and the other to the left (Fig. 1) and the eye needles 25 and 26 are moved forthe distance between the eyes in one needle. In this po- Specification of Letters Patent.
Patented May 15, 19117.
Divided and this application filed June 19,
sition, they remain also during the descent of slide 4. Upon the neXt ascent of the latter, the prism is again turned for a quarter of a turn. Tappet 7 arrives at parallel position to the levers 27 and 28, so that the lat ter can be contracted by spring 31 (Fig. 2). Levers 29 and 30 and thus the eye- needles 25 and 26 move asunder, so that the threads leading through the eyes are placed transversely over the warps and bound.
The object in having two eyes in each of the curved needles, is to allow the employment of two warps, one through each eye, as with one warp only a firm cutting list cannot be obtained.
In Fig. 4, the cutting-list is represented on a larger scale. The threads 31 and 32 are those warps which lead through the eyes 40 of the straight needles 37 and 38, the latter moving not laterally but up and down only. The threads 33 and 34 are those which are guided by the curved eye-needles 26 while the threads 35 and 36 pass through the eyes in the curved needles 25. Owing to the straight needles 37, 38 moving, as already mentioned, not laterally, the curved needles 25, 26 lay their threads once to the left aside over the warps 31, 32 and then again back to the right. The selvage structure shown in Fig. 4, is formed by the up and down movement of the straight needles 37, 38.
What I claim, is:
In a device for making the cutting lists of slit-up fabrics, the combination of an up and down movable slide carrying straight eye-needles, two curved eye-needles movably arranged beside said slide in scissorlike manner and adapted to be moved toward one another upon one ascent of the slide and away from one another upon the other ascent of the slide, substantially as and for the purpose set forth.
