Abstract: 28,758. Delahousse, L. Dec. 31. Loom reeds; beat-up motions; lays.-In a loom which has a stationary lay and a rocking reed, the wett 45, Fig. 6, is brought from the shed by a transporting- device 7 into contact with angular plates or hooks 9, Figs. 1 ... 5, at each side of the loom on a steel bar 41. This bar is grooved to receive the speciallyshaped reed dents or blades 1, which are moved into the successive positions shown in Figs. 1 ... 5. The blades 1 are provided with recesses 13 for the weft. The bar 41 is supported by axles 5, 12, the latter being carried by a rod 2. The axle 5 is actuated by a cam 3. The rod 2 is connected to a bell-crank 15, and is further controlled by the head 6 of a vertical rod 11 and by a lateral abutment 8 thereon, the rod 11 being connected to a lever 38 provided with an abutment 38<1> actuated by the nose 35 and roller 36 of a cam 31, against the action of a spring 44. The cam 3 is connected to an angular rod 4 mounted so as to be free to slide laterally on a pivot 4<b> on the bell-crank 15. When the cam 3 bas been moved to the position shown in Fig. 6, the rod 4 is acted upon by a projection 10 on the rod 11 and moved laterally on its pivot 4<b>. The cam 3 is also moved laterally on its pivot 3<a> out of engagement with the axle 5. The bar 41 then assumes the position shown in Fig. 5, and is moved forwards, while supported by a plate into the position shown in Fig. 1. The cam 3 is then moved into engagement with the axle 5 by means of a bent bar 14 secured to the bellcrank 15. The bell-cranks 15 at each side of the loom are connected by rods 16 to levers 17, Figs. 11 and 6, actuated by arms 18 at the centre of the loom on a shaft 19. This shaft has an arm 20, actuated by lever mechanism 21, 22 and a cam 24. The cam is made so that the extent of the curved part between the parts 26, 27 can be varied, and so that the time of travel of the roller 23 thereon can be changed as required for open and close shed weaving. When the roller arrives at the part 27, it is quickly released. The levers 17 and rods 16 then drop, and, by means of the levers 15 and rod 2, the reed is advanced suddenly into its forward position so as to beat up the weft. The transporter consists of jaws 7, 7<1>, the jaw 7<1> being carried on a pivot 7<5> on an arm 29, adjustably secured on a shaft 37 provided with an arm 29<1> linked to a rocking lever 32. This lever is provided with an abutment 32<1> operated by the nose 35 and roller 36 of the cam 34. The jaw 7 is supported during its rearward movement by a pin 29<2>. A stop 7<6> on the pivot 7<b> prevents the jaw 7<1> from descending during this movement. The jaws are kept separated by a spring 7<4>, and pass over a stop 33 during the forward movement, when they are closed as far as an abutment 7<2> on the jaw 7<1> will allow. The weft 45 comes in contact with the abutment, and is carried to the plate 9 by means of the jaws. A transporting-device may be situated at both sides of toe loom, the shaft 37 being provided with two arms 29.
