A sewing machine which is operable in either a cam controlled feeding mode or a manually controlled feeding mode is provided with a spring which is moved into loading engagement with a feed regulating control lever by mode selecting mechanism when the selecting mechanism is disposed for manual control, and is moved away from the feed regulating control lever when the selecting mechanism is disposed for cam controlled feeding.

Arrangement for suppressing noise and preventing faulty stitch formation

A pattern selecting dial for a sewing machine is connected through a toothed driving belt to a remotely located rotatable member which carries a circularly arranged stepped cam and which can be turned with the application of low torque to the dial to effect the selective positioning of a cam follower opposite a pattern controlling cam stack.

Low torque pattern selecting mechanism for a sewing machine

A sewing machine work feed regulating arrangement is disclosed including a manual control dial for setting the magnitude and direction of work feed and a pattern cam for automatically influencing feed magnitude and direction. Control cam means associated with the manual control dial and effective during a small angular dwell segment thereof influences separate follower means positively to effect either engagement or disengagement of the pattern cam control of the work feed.

Sewing machine cam controlled feed engaging and disengaging mechanism

A sewing machine with a timing belt for transmitting power from a toothed driving pulley to a toothed driven pulley that rotates a loop taker is provided at each pulley on the belt entering side only with a belt guard which guides the belt onto the pulley and prevents teeth on the belt from jumping over teeth on the pulley.

A pattern cam selector mechanism for sewing machines including a pattern cam follower retracting arrangement employing a slidable control block formed with a pair of substantially identical cam tracks disposed laterally opposite each other in mirror image relation, one tracked by a retracting linkage and the other tracked by a stationary abutment pin thereby to minimize functional forces incident to operation of this cam selector mechanism.

Cam selector mechanism for sewing machines

An axially aligned presser bar collar and presser bar bushing in a sewing machine are connected by a helical spring having one end portion affixed to the collar and having the opposite end portion threaded onto a resilient split ring which is located in an annular groove in the bushing.

Presser bar spring-connection

A driving connection between a motor driven belt and the carriage of a knitting machine is provided with disengageable parts which separate when the carriage jams and thereby disconnect the carriage from the belt.

Carriage releasing mechanism for a flat bed knitting machine

An automated flat bed knitting machine including a stationary programmable device with electrical lines corresponding to rows and columns of a fabric producible on the machine is provided with means for extracting information from said device on a row by row basis including switch means operable by the carriage of the machine, motor means controlled by the switch means, and movable contact means controlled by the motor means for sequentially contacting the row lines of the programming device.

Row advancing arrangement for a programmable flat bed knitting machine

A carriage drive is provided for a flat bed home type knitting machine. Such carriage drive includes a reversible electric motor, a pair of motor driven capstans, and wire rope which winds on one capstan and unwinds on the other when the motor rotates, the rope being connected to opposite ends of the carriage of the machine.
