Abstract: A sewing machine wherein there is provided a visual representation of the actual amplitude of vibration of certain stitch forming instrumentalities so that the stitch pattern to be sewn or a portion thereof may be visually superimposed upon the work piece by the operator so that the work piece may be properly positioned and the desired amplitude of the pattern selected.

Abstract: A manually actuatable power control device for controlling a power switch in a portable appliance. The power control device is of one-piece construction and has an integrally formed spring member for biasing the control means to a preferred position. The control means is constrained to partake of linear motion for effecting control of the power switch.

Abstract: A throat plate having means attached thereto for preventing the work limb in a loop of thread from being drawn up through the material being sewn by the take-up limb due to friction therebetween causing a loose stitch known as a halo.

Abstract: A storage cabinet containing a folding cutting table of the type having hingedly connected table top panels which may be extended to form a flat continuous table surface or folded into a relatively compact, stacked assembly and stored within the cabinet.

Abstract: A device for threading the stitch forming instrumentalities of a sewing machine from a thread supply up to a sewing needle. A lever is pivotally mounted in the sewing machine frame and is located at the sewing head which when pulled outwardly, thread, which has been placed across the lever, is drawn into a loop and is urged, by the lever, into a tension device, into a thread take-up lever, and under a check spring assembly.

Abstract: A work feeding mechanism for sewing machines including a feed dog with two pair of mutually orthogonal serrated teeth to drive a fabric past a stitch forming area in directions defined by mutually orthogonal axes. The feed dog is slidably mounted to a bracket which in turn is pivotally fastened to one extremity of a feed bar whose opposite extremity is suspended by gimbals carried in the bed. Means are disclosed to selectively impart oscillations of a varying amplitude and direction to the slidable feed dog in timed synchronization to the work feeding mechanism to drive the feed dog in lateral and longitudinal directions of fabric feeding motion which extend along the length of the sewing machine bed and normal to the length of the bed. Fabric feeding information for the work feeding mechanism may be stored in an electronic memory to permit the production of ornamental stitch patterns.

Abstract: The instant invention provides, in combination, a metal part having a cylindrical opening, a chamfer below the cylindrical opening, and an aperture below the chamfer, the diameter of the cylindrical opening being less than the diameter of the aperture at the juncture of the aperture and the chamfer, and glass fused only to the wall of the cylindrical opening.

Abstract: An automatic control means for overriding the manually operable fast/slow control switch of a sewing machine to assure slow speed operation while the machine is operating in skip stitch mode, such as while basting to facilitate positive latching and unlatching of the needle bar. The automatic control means cooperates with the needle bar lateral jogging mechanism of the sewing machine such that when the needle bar is jogged beyond a predetermined range of laterally jogged positions, wherein skip stitch mode is effected, the automatic control means will automatically impose slow speed operation independent of the setting of the fast/slow control switch as selected by the operator.

Abstract: A thread guiding system for sewing machine bobbin winders in which the last thread constraining eyelet is positioned laterally centrally of the bobbin spindle and a plurality of smooth surface guide pins are positioned between the thread constraining eyelet and the bobbin with the axis of each pin parallel to that of the bobbin spindle. The pins exert no lateral influence on the thread which is allowed to move freely along the pins. With this construction the distance from the last thread constraining position to the bobbin is greatly reduced from that normally required for smoothly winding thread uniformly about the bobbin.
