摘要： A looper lubricating device for a sewing machine includes an oil line having an inlet submerged within an oil supply and a capillary member within the oil line at a spaced location from the inlet and the oil supply. An outlet of the oil line is in fluid communication with an injection nozzle and the capillary member protrudes through the outlet of the oil line into a mixing chamber within the injection nozzle. A gas conduit communicating with the mixing chamber is operative to intermittently produce a pressure gradient between the inlet and the outlet of the oil line to pass oil to the mixing chamber.

摘要： A sewing machine for wrapping button shanks comprises a holder for a workpiece to which a button is attached by means of shank loops. To adjust the work holder to the length of the shank loops, two spaced apart holding elements are provided by which the work is separated from the button and which can be positioned at the desired distance from each other. To cut the sewing thread, a cutting blade is displaceable in one of the holding elements and the cutting edge of the blade is movable transversely to the needle path, between the inserted shank loops and a rotary hook.

摘要： A feed drive for a stitch group sewing machine includes a cam plate serving to drive a work clamp. The cam plate is connected to a controllable clutch driven from the drive motor of the sewing machine. In order to keep the stitch length constant at varying lengths of the stitch group, the output speed of the clutch is controllable by a control device as a function of the rotational speed of the sewing machine of the transmission ratio of a gearing between the cam plate and the work clamp which determines the length of the stitch group, and of the adjusted stitch length. The stitch group to be sewn may be divided into two sections having their stitch lengths variable independently of each other, by providing that a switch responsive to a partial revolution of the cam plate corresponding to the length of the first section, alternately connects one of two potentiometers which determine the stitch length, to the control circuit of the clutch.

摘要： A feed drive for a stitch group sewing machine includes a cam plate serving to drive a cloth clamp and it is connected with a separate motor. In order to keep the stitch length constant at varying length of the stitch group, the motor speed is controllable by a control device as a function of the rotational speed of the sewing machine, of the transmission ratio of a gearing between cam plate and cloth clamp which determines the length of the stitch group, and of the adjusted stitch length. The stitch group to be sewn can be divided into two sections with a stitch length variable independently of each other, in that a path-dependent switch operable after a partial revolution of the cam plate corresponding to the length of the first section alternately connects one of two potentiometers which determine the stitch length, with the motor control circuit.

摘要： A sewing machine comprises a sewing machine support arm with a cloth feeding plate mounted on the support arm over which the material to be sewn is fed. A stop element is mounted on the support arm and it overlies the cloth feeding plate and it includes a portion which defines a material stop against which the material to be sewn may be positioned. The stop is made of a compressible material and it is compressible in the direction toward the feeding plate. A presser plate associated with the machine may advantageously be in the form of a button clamp may be moved downwardly into engagement with the stop which is raised slightly above the material and compress it downwardly until the plate clamps the material in place for the sewing operation.

摘要： A device for use with sewing machines for transport of work pieces. The transport device removes finished workpieces from a sewing area and feeds the workpieces to a transfer point at which the end section of the work piece is held with little force to allow the workpiece to be gripped by a stacking element. The arrangement allows for the next workpiece to be inserted into the sewing area simultaneous with the removal of the finished workpiece. The transport device includes a swivelable arm carrying a driven conveyor belt. The arm may be swivelled upward once the front section of the work piece has been moved underneath the swivelling axis of the arm, so that a new workpiece can be inserted. The conveyor belt can be arrested before the end section of the workpiece passes through. The conveyor belt contact pressure can be reduced such that the work piece can be pulled out easily by a stacker.
摘要翻译：一种用于缝纫机运输工件的装置。运送装置从缝纫区域移除成品的工件，并且将工件送入传递点，在该转移点处，工件的端部被很小的力保持，以允许工件被堆叠元件夹紧。该布置允许下一个工件在与完成的工件的移除同时插入到缝纫区域中。运送装置包括一个承载着从动输送带的可旋转臂。一旦工件的前部已经移动到臂的旋转轴线下方，臂可以向上旋转，以便可以插入新的工件。传送带可以在工件的端部通过之前停止。可以减小输送带接触压力，使得工件可以通过堆垛机容易地拉出。

摘要： A feed drive for the work holder of a zig-zag stitch group sewing machine comprises a rotatable cam plate and a work holder which is engaged with the plate and moved thereby within a rectilinear guide arranged adjacent the head portion of the sewing machine. The work holder is located adjacent the needle and it includes a driver plate which extends below the sewing machine arm portion and grips the workpiece from above. The cam plate is arranged in a standard of the machine and the work holder is driven by engagement of a sensing element in a groove of the cam plate which is connected to the work holder through a lever drive acting on a rotatable shaft arranged below the arm of the machine and connected with a crank and a link with a slide carrying the work holder which is disposed in a guide. The construction includes a seating for the workpiece which is movable parallel to the guide and is coupled with the driving plate. This comprises two endless belts which are disposed on freely rotatable guide rollers and which have a spacing corresponding to the maximum swinging amplitude of the needle.

摘要： A sewing machine with a drive for a work clamp comprises two slides movable relative to each other, one carrying the work clamp and the other carrying two tail wheels and an endless belt trained thereabout. Two stepping motors which can selectively be run in the same or in opposite directions are engaged each with a respective one of the belt strands, so that with the motors running in opposite directions, the two slides move in the lengthwise direction, while with a run in the same directions, only the slide directly carrying the work clamp is moved, namely transversely. In another embodiment, the slide directly carrying the work clamp is non-rotatably connected to one of the tail wheels.
