THREE-STORIED LATHE FO'R RIBBON LQOMS.
Application filed. February 10, 1922.
To all whom it may concern:
Be it known that I, GUsTAv Lfinonr, a citizen of the German Republic, and residing at Barmen, Germany, have invented certain new and useful Improvements in Three-Storied Lathes for Ribbon Looms (for which I have filed application in 'Germany on F ebr. 14th, 1921), of which the following is a specification.
This invention relates to improvements in three-storied lathes for ribbon-looms, and more particularly to improved means for operating the shuttles thereon, by which it is possible to weave ribbons arranged in three offset rows above one another, so that an easy access to each row of ribbon is warranted during the work.
According to the invention, the shuttles of the middle row are operated by means of toothed racks arranged above and below the same. The improved three-storied lathe may be constructed as a single-shuttle or as a double-shuttle lathe.
The accompanying drawing represents, by way of example, three appropriate constructional forms of the improved lathe:
Figs. 1 and 2 are, respectively, a fragmentary elevation and a section (on the line AB of Fig. 1), of a single-shuttle threestoried lathe;
Figs. 3 and 4 are a similar elevation and section, respectively, to the former, of the same lathe having, however, a difierent shuttle driving mechanism;
Figs. 5 and 6 are a fragmentary elevation and a section (on the line CD of Fig. 5) respectively, of a double-shuttle threestoried lathe.
Fig. 7 is a similar view to Fig. 3, and it illustrates the rack and pinion structure for operating the shuttles and an example for the movement of the toothed racks, while Figs. 8 and 9 are a sectional side view and a sectional plan view respectively on the lines EF and G-H of Fig. 7.
It may be mentioned that the usual reeds for beating-up the wefts inserted by the shuttles are not shown on the drawing.
As shown in Figs. 1, 3 and 5, the openings 1, 2, 3 for the three superposed rows of ribbon are oflset With reference to one another. Through said openings, the shuttles arranged in rows 4, 5, 6 can be driven to and fro, the corresponding guiding-members be- Serial No. 535,630.
ing situated between the upper block 7 and the lower block of the lathe 8.
The 'to-and-fro movement of the three shuttle rows may be explained with reference to Figs. 1 and 2.
In the lower block 8 and in the upper block 7, double toothed racks 9, 10 and 11, 12 respectively are provided, which are reciprocated in a way known in the art such as indicated below at the lower block 8 through the medium of roller-guided belts m. The toothed racks 10 and 12 move the lower and upper shuttles 4 and 6 directly by means of pinions 13 and 14, in a way known in the art. The middle shuttle row 5 can be brought from one end position to the other neither from below alone nor from above alone by means of one toothed rack only. Therefore, provision is made that said middle shuttle row 5 is operated from the lower toothed rack 9 as well as by the upper toothed rack 11 by means of pinions 15, 16 and 17, 18 respectively. Each of the two toothed racks, the upper one and the lower one, moves thus the corresponding middle shuttle 5 from one end position for about half of its stroke toward the other end position, the remaining half of the stroke being completed by the other toothed rack. During the return stroke of the shuttle, the proceeding is the same but vice versa.
Figs. 3 and 4 show how the driving of the shuttles 4, 5, 6 is effected by means of a plurality of pinions 21 keyed on perpendicular spindles 22 and which gear with a corresponding toothing on the rear side of each shuttle and with correspondingly arranged toothed racks 19 and 20 (Fig. 4), which are reciprocated in any way known in the art. As shown in Fig. 3, there are short spindles 22 having each two pinions 21 and which transmit the movement of the toothed racks onto the shuttles of the lower and upper row, while there are long spindles 22 having each three pinions 21 and which act upon the middle row of shuttles. Also, in this case, each middle shuttle 5 is moved for about half of its stroke from one toothed rack while the remaining half of its stroke is completed by the other toothed rack.
Figs. 5 and 6 show a double-shuttle threestoried lathe, the driving mechanism of the shuttle being the same as shown in Figs. 3 and 4 but with a double arrangement of the tively above and below said shuttle rows,
Figs. 7, 8"and '9illustra-te the rack and pinion structure for operating the shuttles and an example for the movement of the toothedraoks 19 and 20 which are joined by a connection member 23, two belts 24 guided over fixed rollers 25 being connected with the lower toothed rack 19 and adapted to be driven in a Way known in the art by a cam and lever mechanism (not shown). What I claim, is a 1. In a three-storied lathe for ribbon looms, three superposed ofiset rows of shuttles, two reciprocating toothed rack arrange ments located in the upper part of the lathe and 111 the lower part of thesame respecand combined means for driving the upper shuttle row from the upper toothed rack arrangement, the lower shuttle row from the lower toothed rack arrangement, and the middle shuttle row for half of its stroke from one of said toothed rack arrangements and forthe: remaining half of its stroke from the other toothed rack arrangement,
substantially as set forth. V
2. In a three storied lathe forpribbon looms, two superposed ofiset rows of double shuttles, two reciprocating toothed rack arrangements'located in 'the upper 'part ofth'e lathe and in -the lowerpart of the same respectively above and below said shuttle rows, andcombinedmeans for driving the upper shuttle row from the upper toothed rack arrangement, the lower shuttle row from the lower toothed rack arrangement, and themiddle shuttle row for halfo f-its stroke from one of said toothed rack arrangements and for the remaining half of its stroke from the other toothed rack arrangement, substantially 'as'and for 'thepurpose =-set forth. v
In testimony whereof I have; hereunto set my hand in the "presence of two subscribing witnesses. V n h r GUSTAV LUDORF.
