Abstract: A sewing machine having a device for manually changing a feed dog (10), including the feed dog (10) and a feed-dog holder (30). The feed-dog holder (30) is disposed in an arm bed (103) that is associated with the sewing machine, and the feed dog (10) is receivable in a clearance (31, 81) of the feed-dog holder (30). The feed dog (10) that is located in the clearance (31, 81) has a support face (15) which may be disposed parallel with the surface of a sewn-product support which may contain a needle-hole plate (113) or be configured as a needle-hole plate (113), the sewn-product support and/or the needle-hole plate (113) may at least partially be formed by the surface of the arm bed (103), and the support face (15) may be received in an opening (140) of the needle-hole plate (113).

Abstract: The activation for a path and time related motion of a thread cutting and lead-in stitching unit (7) and the thread brake (25) occurs by a cam drive driven by the primary shaft (9) and a cam drum (75) arranged on the upper shaft (17). This way, an absolute synchronization of the elements of the thread cutting and lead-in stitching unit (7), the thread brake (25), and the hook as well as the needle is ensured.

Abstract: For the continuous drive of a hook of a sewing machine, two drive cams (17) alternately engage in the back of the hook. During the passing of the upper thread loop, the respective drive cam (17) on which the thread would get hung up is out of engagement. The hook is situated in a conical hook race guide and is held therein by magnets.

Abstract: A method for cutting the lower and at least one upper thread for lead-in embroidering or lead-in sewing is performed with a device including thread catchers (19a-19c) connected with each other in a fixed manner and layered over top of each other, formed of sheet metal, as well as spring and thread tightening plates (31 and 41) arranged above and below the thread catchers, which move back and forth against a blade (29), and a thread wiper unit. The device is exclusively operated by a drive moving back and forth and driving the thread cutting and lead-in stitching unit (5).

Abstract: A locking mechanism for a bobbin case (5) is provided with a locking lever (35) supported pivotally in the bobbin cover (27). The locking lever is pivotal on a shaft (33). A hook-shaped end (51) is formed at the locking lever (35), which latches in the sleeve (9) in the hook and can hold the bobbin case (3) in the hook (1).

Abstract: A volatile material dispensing device is provided, including a reservoir containing a supply of any one of numerous volatile materials having an outlet port with attached tube through which the volatile material flows, a valve and valve adjustment mechanism to control the flow rate through the tube, a lower housing incorporating a pad to receive the volatile material, and a tear-off tab that initially seals the tube and prevents flow until removed by the consumer. Optionally, the device may include an active mechanism, such as a fan, to aid dispersal of the volatile material. The device gives the user control of the intensity of the vapor by providing the ability to adjust the flow through the valve with the valve adjustment mechanism. The device also provides constant vapor intensity over time with a time-release dispersing mechanism delivering a controlled, consistent flow, with an appropriate drip rate.

Abstract: A volatile material dispensing device is provided, including a volatile material, a replaceable canister including a U-shaped outlet tube and a reservoir to hold the volatile material, and a generally cylindrical external housing sized and configured to receive the replaceable canister. The U-shaped outlet tube includes a tube inner leg, a tube crosspiece, and a tube outer leg, with the tube inner leg fluidly connected to the cavity and with the tube outer leg open to the atmosphere. The external housing includes a powered actuating unit configured to apply pressure to the flexible outer wall of the reservoir. Thereby a portion of the volatile material is forced up the inner tube, over the tube crosspiece, and down the outer tube to be received by a porous pad, providing a time-release dispersing mechanism delivering a controlled, consistent flow and producing a constant intensity of vapor release over time.

Abstract: A device for operating several sewing functions is provided with a single control disk with curved paths arranged peripherally and facially on the control disk for acting radially and axially. The control disk is driven by a stepper motor and allows individual or several functions to be executed during the rotary movement as well as temporarily stopping others.

Abstract: An embroidery module (1) is provided that is attached (docked) to the base plate (29) of a sewing machine (27) and supplied with power and control commands from the machine electronics. A free space (33), which permits the insertion of tubular work pieces around the free arm (31), is created between the embroidery module (1) and a front end of the free arm (31). The embroidery module (1), with or without an embroidery hoop support (13), can remain docked for all sewing, embroidery, and quilting work on the sewing machine (27).

Abstract: In an upright (3) of a sewing machine (1), a thread spool holder (24) is mounted in a recess (13) so that it can pivot out of the recess (13). On this holder, thread spool pins (23) are placed, as well as an arm (35), on whose upper end thread guidance elements (33) are fixed. For use, the cover (15) which covers the thread spool holder (24) in the stowed state is opened, and the thread spool holder (24) is pivoted out from the recess (13).

Abstract: The hook (15) of a sewing machine (1) is mounted so that it can move on a hook carrier. Through a sliding movement of the hook carrier, the hook (15) is brought from its operating position into a bobbin case removal position. Through the sliding movement, the hook (15) with the bobbin case (17) is placed at or above the opening, which is created by the flap (13) in the lower arm (5). In this way, the removal of the bobbin case (17) or the bobbin is made considerably easier.
