Abstract: A transfer device for depositing flatwork on a continuously movable flat feed belt having a collector rod mounted to reciprocate in a substantially horizontal path to engage a surface of a vertically hung flatwork. An unrolling rod is mounted in association with the collector rod to move in an orbital path about the collector rod. Collector rod and unrolling rod are arranged to operate cyclically in a first collecting stage in which on engagement of the collector rod with the surface of the flatwork an edge of the flatwork is laid over the collecting rod and carried thereon and a second unrolling stage in which the unrolling rod passes about the collecting rod to engage the rear surface of the flatwork and in cooperation with the collecting rod lays the flatwork in stretched condition on the feed belt.

Abstract: An upper torso frame includes a pair of vertical members with a waist well extending between and connected to the lower end portions of the vertical members. A shoulder member is positioned on the vertical members upper end portions. The shoulder member is connected to the upper ends of the vertical members for forward and backward pivotal movement. A pivot carrying link is connected by friction hinges at one end to each vertical member upper end portion and at the opposite end to the upper portion of an arm member so as to pivotally connect a pair of arm members to the upper torso frame. The pivot carrying link is pivotal on the torso frame and each arm member is pivotal on the pivot carrying link to thereby provide multiple degrees of pivotal movement of the arm members relative to the upper torso frame.

A space is provided between the rear end of the needle plate for the overlock stitch mechanism and the front face of the free arm, through which a fabric to be stitched passes.

Abstract: A work feed device for sewing machines, which comprises feed dog carrier bars performing an elliptical movement with the aid of two mechanisms; namely, an advancing mechanism and a raising mechanism. The advancing mechanism is composed of an oscillating shaft provided with arms, which in turn are connected to the feed dog support bars at the opposite end to that where the dogs are mounted. The raising mechanism comprises a support making a vertical reciprocating movement and which is provided with a horizontal guide along which the feed dog support bars are moved reciprocatingly by the advancing mechanism. Finally, vertical movement of the support comprises two connecting rods approximately parallel to one another. They are pivoted at one end to the said support and at the other end to a part connected to the frame of the sewing machine.

Abstract: In a tiltable window, especially to be mounted in a sloping roof, the lateral members of the sash and frame carry external cover rail sections which in the closed position of the window overlap each other in the area of the hinge device of the window. The hinge device consists of a frame part and a sash part and of an intermediate part connected with each of the two parts by means of two parallel pivot pins which in the closed position of the window are situated within the outer side of the window and are protected by the cover rail sections. During the opening movement of the sash, its hinge part is first rotated in relation to the intermediate part while this part is locked to the frame part by means of a latch, and after the forcedly controlled release of the latch, the sash part and the intermediate part together can rotate further in relation to the frame part.

Abstract: A butt hinge includes a first hinge plate with a pair of axially spaced outer gudgeons extending from an edge of the first hinge plate, a second hinge plate with a gudgeon formed of two axially spaced gudgeon sections extending from an edge of the second hinge plate between the outer gudgeons extending from the first hinge plate, and a hinge pin extending through the gudgeons of the first and second hinge plates for pivotally connecting the first and second hinge plates. The pin is fixed against rotation within the outer gudgeons of the first hinge plate, and a bearing bushing within each of the gudgeon sections of the second hinge plate supports the pin for rotational movement about its axis when the first hinge plate is pivotally moved relative to the second hinge plate.

Abstract: A guide for sewing machines for effecting the attachment of a waistband to a workpiece which includes a pair of U-shaped guide elements fixed on the machine in spaced and vertical alignment for guiding separated strips of band material to a converging position in close proximity with the machines stitching instrumentalities. The guide includes a dividing member selectively movable from an operative position between the guide elements to a position displaced therefrom. The dividing member is provided with surfaces that cooperate with the guide elements to form separate passageways for the strips of band material and a central member having a guide surface for guiding the edge of the workpiece between the separated strips of band material to the converging position.

The invention further includes sensing elements arranged to monitor the position of the workpiece edge and devices operatively associated with the sensing elements and the servosystem for automatically adjusting the feed rate of the auxiliary mechanism according to the characteristics of the work being sewn and for effecting the speed of the auxiliary mechanism relative to the velocity of the workpiece whereby maintaining the desired alignment of the workpiece edge relative its predetermined position or path during the sewing operation.

Abstract: The helmet, at its face opening, is provided with a peripheral abutment in which the edge of a transparent shield is housed, such that the visor when closed is flush with the surface of the helmet. Such shield is connected to the helmet structure by articulation members which are connected to members such as multiple hinges comprising links or the like. The length of the hinge members can be varied to allow the shield to be moved away and removed from the peripheral abutment and then tilted.

Abstract: Fabric is knitted by a stick-like double-hooked needle. The stick-like double-hooked needle which knit reversible Afghan stitches comprises a stick-like stem having the same diameter throughout the length thereof and hooks formed on both the ends of the stem and having a size substantially equal to the diameter of the stem. Each hook is a sharpened top end and both the hooks have the same configuration.

Abstract: The method for monitoring the operative position data of each of a plurality of independent separately operable knitting machines and transferring such information to the address input of a common memory control system for controlling the patterning of each machine, is obtained by generating a pick-up pulse at each machine indicative of the passage of its needles and of the completion of each course past a given point. A continuous cycle of timing pulses each of which corresponds to a selected knitting machine for which data is to be monitored is provided. In response to each of the individual timing pulses the respective generated pick-up pulses are fed to a logic control sweep circuit, the output of which is fed to one input of an adding circuit. Simultaneously a second input is fed to the adding circuit comprising the position data information of the immediately preceding needle and course, which had been stored in a random access memory unit corresponding to the particularly monitored machine.

Abstract: A knitting machine in which the needle selection is performed electromagnetically from a programmed control. Selectors having spring return means are adapted to occupy an operative position in which they engage means for moving the needles to their working position. The selectors are attached to the knitting machine frame and are moved against said spring means by cocking members mechanically connected to the knitting machine needle bed drive means. An electromagnetic holding means attached to the machine frame and associated with the cocking members is arranged selectively to hold the selectors in the cocked position when driven by a programmed control synchronised with the needle bed movement and with the selection device.
