Abstract:
A Jacquard machine, having at least two knife grids (5, 6)moving up and down in opposition on either side of the Jacquard machine, the Jacquard machine having a single-sided drive (1) for driving at least one driving lever (2,3) which is provided for driving the motion of the knife grids (5, 6) on either side of the Jacquard machine, and one traversing rocking shaft (24) being provided to transmit the motion of the driving lever (2 and 3 respectively) to the knife grids (5,6) of one of the sides of the Jacquard machine.
Abstract:
A heald frame comprises: a heald support frame for supporting a plurality of healds in parallel, the heald support frame having a central plate portion and a pair of ring-shaped rectangular heald supporting portions extending in opposite directions from the central plate portion; and a heald support extending perpendicularly from the central plate portion, the heald support being integrally connected to the central plate portion of the heald support frame via a generally V-shape joint. The heald frame is made from a reinforced composite material composed of a synthetic resin and a reinforcing filler. Each of the heald supporting portions includes one lower supporting rod for supporting at least a heald.
Abstract:
A heald frame for a weaving loom comprising an upper cross-member and a lower cross-member adapted to support healds directly therebetween. The upper and lower cross-members are joined together by spaced end members and a plurality of connection members spaced along the length of the cross-members between the end members and attached to the cross-members to restrain relative movement between the cross-members and retain a constant spaced relationship between the cross-members along their length. The connection members have portions of a narrow width extending between the upper and lower cross-members so that, during weaving, warp yarns pass the connection members without interference. First and second connection members are disposed, respectively, at opposite ends of each connecting member for causing reciprocation of the frame.
Abstract:
The two-phase gripper loom or weaving machine comprises two loom units arranged adjacent one another. Each of their heald frames can be actuated by a heald frame positioning device with a phase shift of 180 angular degrees. Each heald frame positioning device is associated with a related one of the loom units. There is arranged between the common main shaft of the machine and the two rotary shafts of the two heald frame positioning devices a clutch drive for selectively individually connecting or coupling one or the other rotary shaft with the main shaft of the machine or with an auxiliary drive. This enables, during standstill of the machine, to bring the open weaving shed of one or the other loom unit into a closed shed position until the gripper loom is restarted, prior to which restarting the closed weaving shed is brought back again into the open shed position.
Abstract:
The eccentric mechanism includes deflecting levers which are rotatably mounted on a fixed spindle and which bear against bearing elements in order to preclude an accumulation of tilting forces along the line of the levers. Each bearing element has a disc-shaped portion located between two levers and cooperates with a bushing, separate or integral, or a shaft portion to mount a lever.
Abstract:
The invention relates to apparatus wherein loom harnesses are operated by cams driven intermittently by respective drives rather than by cams fixed on a driven shaft. The harnesses are illustrated as being lowered by cams against yieldable resilient means tending to raise the harnesses, and the cams as being aligned with treadles carried longitudinally of the loom. Co-acting means are also provided for connecting respective chain drives at predetermined intervals to bearing members, rotatable on a fixed shaft, which carry cams fixed thereto as well as chain carrying sprockets rotatable thereon. The method contemplates operating the harnesses by timing the steps of rotating each cam in a predetermined sequence, and exerting a yielding force upon each cam tending to resist further rotation after the cam has turned on the fixed shaft through a predetermined arc.

448,096. Vehicle spring-suspensions. PORSCHE GES., DR. ING.H.C. F., 24, Kronenstrasse, Stuttgart, Germany. Feb. 11, 1936, No. 4102. Convention date, Feb. 11, 1935. Addition to 385,812. [Class 108 (ii)] In the vehicle suspension described in the parent Specification in which the torsion springs are enclosed in a hollow transverse member to which the bearing casings for the link arms carrying the wheel are connected by flanges and bolts the bearing casing for the link member journal is provided with a cylindrical extension which is welded to the hollow member. As shown the bearing casing 23 is provided with a cylindrical extension 39 which is welded in the end of the transverse member 34 housing the torsion bar springs 29, 29 . The casing 23 is provided with two journals 16, 17 of which the latter is connected to the appropriate torsion spring, the journals forming part of or connected to the link members 12, 13. The journals 16, 17 are positioned axially by collar bearings 41, 42 with which collar abutments 43, 44, inserted in openings in the casing 23, engage. The journals 16, 17 are also provided with roller bearings 18 , 20a and bushes 19, 21 and the lower journal 16 is provided with a cross pin 53 adapted, by means of two extensions of the casing, to limit the amount of rotation or oscillation of the journals and consequently the wheel-carrying links 12, 13.
