Abstract: Shifting arrangement for a gear transmission constructed in sections to be used for vehicles. With a common manual clutch (2) a parking lock, a reversing transmission and a range-change transmission are shifted. The movements of the manual clutch (2) in the shifting direction, respectively in the longitudinal direction of the vehicle, actuate in a purely mechanical manner the shifting of the parking lock and the reversing transmission. Movements of the manual clutch (2) in selection direction, respectively transversally to the longitudinal direction of the vehicle, actuate mechanically and hydraulically the shifting of the range-change transmission. Mechanical locking devices prevent undesired shifting.

Abstract: A thread clamp for sewing machines comprises a helical spring as a clamping element which is disposed in a bore extending crosswise to the feed direction of the work in a guide piece placed on the stitch plate. To obtain a very short closing path, the helical spring has in the region of the respective thread pull-off path windings whose mutual distance is greater than in the other regions. The helical spring is compressible by a setting drive for the fixed clamping of the threads.

Abstract: A device is disclosed for pulling out and cutting off the needle and looper threads in a sewing machine with a delivery roller for delivering material to the machine sewing station. The delivery roller is driven over a first drive, which is dependent on the sewing machine main drive and over a second drive, which is independent of the sewing machine main drive. On the looper of the sewing machine is secured a cutting blade for the needle thread. Furthermore, a needle thread clamp is provided. In order to manage, with a single means for pulling out the needle and looper threads by different lengths, a cutting device for the looper thread is arranged between the cutting blade and the delivery roller, with a guide which is traversed by a thread inlet groove and with a counterknife for a thread severing knife that moves transverse to the material feeding direction. The delivery roller is driven over the second drive for pulling out the threads.

Abstract: A guiding device for sewing machines which have means for feeding cloth of workpieces into association with a moving needle in a stitch forming area for effecting edge parallel seams, comprises a support table with a bottom plate supported on the table and having at least a portion spaced above the table and defining a cloth layer feed space and with a top plate overlying at least a portion of the bottom plate and spaced above it and defining a workpiece layer passageway therebetween. The top plate has a pressure point which may be urged toward a complementary point on the bottom plate at a location spaced from the stitch forming area. A plurality of pins supported on the bottom plate and extending upwardly through the top plate are arranged to extend laterally and in an acute angle to a line extending in the workpiece feed direction.
