UNITED STATES PATENT OFFICE 2,107,592 LOOM FOR WEAVING Jakob Wolfensberger, Bauma, Switzerland Application January 9, 1936, Serial No. 58,429 In Switzerland January 16, 1935 1 Claim. (Cl. 139-491) This invention relates to a weaving loom with a stationary frame. ' thrust rod 6 is mounted and which moves in the sliding track II’. By this device a variation of According to the invention the beating-up the path described by the beating-up comb 9 is comb thereof is mounted between the ends of 5 thrust rods each of which is jointed at one end to a rotary crank and has its other end mounted in ?oating manner, and one of the longersides of the resulting substantially ovoid or pearshaped path which the operative part of the 10 comb follows in making a beating-up movement is arranged to lie within the zone of the shed. The invention provides, therefore, a simple means whereby the comb makes its beating-up strokes in the shed and its return strokes in a 15 path lying outside the shed zone so that weft can be laid during the return movements, the time available for the laying being increased or it being possible to run the loom faster than has generally been the case hitherto, 20 The shuttle track is preferably formed by a rake and the reed of the stationary slay which also provides a lateral guide for the prongs of the beating comb. The invention will now be described with ref25 erence to the accompanying drawing, wherein: Fig. 1 shows a diagrammatic cross section of the weaving machine; Fig. 2 shows a diagrammatic plan (beating comb in the beating-up position); 30 Fig. 3 shows a modi?cation of the suspension for the thrust rods in adjustable sliding guides. The reed 2 is connected to- the stationary slay vI. The shuttle track consists of a rake in the rendered possible. The method of operation is as follows. 5 By turning the crank shaft 1, the beating-up comb 9 describes with the upper ends of the prongs, a substantially pear-shaped or ovoid curve ID’ of which the point is located at the beat-up edge H’ of the woven material. By 10 means of shuttles 16, the track of which being formed by the reed and the rake, a Weft is in serted when the shed is open. At the moment the shuttle passes out of the shed the crank pins ‘l have reached the rear dead centre, the beating 15 prongs It! being in the position before fully en tering the shed. Simultaneously, however, the shed commences to change and the Points Of the beating prongs 10 are able to follow the lower warp during the upward movement up to the 20 middle, that is to say, until the two warps meet. The weft thread is located and held between the warp threads and is now beaten-up by the comb 9 or beating-up prongs I0, while the shed con tinues to change completely. The points of the 25 prongs pass closely over the dents of the reed, the weft is caught by the prongs without fail immediately after the descending upper Warp has crossed into the comb. Already before the front dead centre of the crank is reached (beat- 30 ing position shown in chain dotted lines in Fig. 1) the shed may be opened to such an extent that the shuttle may again enter. It then has fOI‘m of guide plates 3 which are Secured at One 35 end in the transverse member 4 and which with the other ends reach up to dents of the reed 5. The shuttles used may be of any Standard Shape- available the period of time corresponding to half a revolution of the crank shaft for travers- 35 ing the warp, that is to say, unt? shortly before the rear dead centre is reached. It is thus possi The thrust rods 6 'are reciprocated by the Crank pins 7 and rock With tiheil‘ front ends 011 rocking 4O levers 8. Between the ends of the thrust rods 6 is secured the beating comb 9 with the beating prongs l0. Each prong l0 slides between two ble to provide for the shuttle about half the time of operation more than is possible in an ordinary 1o0m_ In other words; with the same time of 40 movement of the shuttle, the crank Shaft may move about 50% faster_ During the return guide plates 3 without completely leaving these.
