A needle thread end holder for a sewing machine having bobbin thread replenishing mechanism in which an annular groove formed in the presser securing screw accomodates a stretched rubber 'O' ring so as to apply only a limited frictional resistance to a thread introduced beneath the 'O' ring insufficient to abort a bobbin thread replenishing operation.

An angularly configured bracket is mounted at one end portion for pivotal adjustment in a sewing machine into a position of engagement at another end portion with fixed machine structure. A fastener extending through a slot in the bracket while the bracket is so adjusted secures the bracket to the upper end of a fixed post having a rotatable work feed controlling cam thereon, and so stabilizes the post against distortion by a spring biased cam engaging follower.

Stabilizing arrangement for a sewing machine cam post

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.

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.

A sewing machine is secured to the platform of a sewing cabinet with a machine connected stud and a wing nut which is threaded on the stud and is permitted to turn only a limited amount so as to prevent excessive force from being applied to the machine.

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.

The meshing bevel gears used to drive the vertical axis looptaker of a sewing machine are preloaded with a compressed resilient member which is prevented from deflecting to a position beyond its elastic limit during the running of the gears.

Noise reducing arrangement for gears

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 bushing, sleeve, bearing or like part is secured in a structural member with a clamping device which is screwed into the structural member at right angles to said part to cause a tapered portion of the device converging toward terminating a reduced diameter material end portion to forcibly engage the said part.
