Abstract: A high speed, portable, rug binding machine in the form of an electric-powered hand-tool carrying and dispensing a roll of binding tape has floor-engaging canted wheels for directing the frame of the machine into a rug as it is rolled along a rug edge to which a binding is stapled by the machine as the operator pulls a trigger causing a solenoid to drive the stapler by way of a power linkage which automatically adjusts for rug and for binding thickness; the machine has adjustment for varying rug-to-binding holding force, prior to stapling, and rug introduction angle; simplicity of mechanism provides compactness and light weight suitable for one-hand manipulation by the operator under all conditions.

Abstract: A portable bag-closing sewing machine is provided with a self-oiling system which includes an oil reservoir connected to the machine and oil-delivery means to direct oil from the reservoir into the inner chambers of the machine where oil is distributed by gravity flow, capillary action and movement of machine components, the oil moving along through the machine components and through a series of channels, troughs, and reservoirs within the housing to distribute oil throughout the machine. During operation, the rotating and reciprocating machine parts fling oil outwardly within the chambers to directly oil machine assemblies and to create a fine mist of oil throughout the chambers so as to further lubricate machine components. Also disclosed is an improved and self-lubricating feed dog assembly and thread chain cutting device.

Abstract: A toy device adapted to loop a strand such as yarn through sheet material such as resinous foam fabric so as to simulate sewing or other needlework. The overall shape of the device simulates a sewing machine, that is, includes a platform on which material to be worked is held and a head supported in vertical spaced relationship thereabove. A hollow needle through which a strand may be threaded is supported on the bottom of a reciprocal plunger which when moved up and down, as by the child manipulating the device, causes the needle to project through the material and causes a series of loops to be formed on the back face thereof. A strand inserting device including a vertically reciprocal rod is positioned in alignment above the open end of the needle so as to thread the same. In the upper position of the plunger, the rod is independently operable from the plunger but acts in conjunction with the plunger in its lower position for safety purposes.

Abstract: A button attaching tool is provided with a base, a pair of needles which have collapsible and expandable thread receiving eyes and which project from the base for use in penetrating a layer of material and the holes of a button to be attached to the material, and a member for stripping the material and button from the needles.

Abstract: Disclosed is a lightweight, inexpensive toy electric sewing machine made primarily of molded plastic components which are easily assembled with minimum of tools.

Abstract: The invention contemplates a hand-held and hand-operable stitching device capable of performing a stitching operation at substantial offset from the region of manual contact. The stitching is performed as a special filament-carrying needle is shuttled in a reciprocating cycle of alternated release and retention at corresponding needle-retaining ends of two arms having articulated connection remote from their needle-retaining ends.

Abstract: A suturing device comprising a drive shaft and an oscillator for oscillating the drive shaft about an oscillatory axis. A suturing needle is coupled to the drive shaft so that the drive shaft can move the suturing needle back and forth along a first path. A loop arm is mounted for movement along a second path generally transverse to the oscillatory axis. The loop arm is drivingly coupled to the drive shaft to permit the drive shaft to move the loop arm back and forth along the second path.

Abstract: A hand held and flexible drive shaft powered apparatus is provided for movement along an incision made in flesh or other material and to be sewn closed. The apparatus includes a pair of opposite side drive wheels which are driven from the aforementioned flexible shaft and engage the flesh or other material on opposite sides of the incision therein. The apparatus is driven in a forward direction by the drive wheels along the incision and the forward portion of the apparatus includes a stitching mechanism including an arcuate reciprocally driven needle as well as an oscillatably supported and driven looper whereby a blind suturing operation may be accomplished to close the incision as the apparatus is driven along the incision by the drive wheels.

Abstract: A semi-automatic crocheting tool has a chassis including a yarn-receiving assembly with a hook, a needle normally spaced from the hook, and means for selectively engaging and disengaging the needle from the hook. The tool has a counting feature which automatically counts the number of times the needle engages the hook, and thus keeps an accurate record of the number of stitches completed. Additionally, a manual counting device facilitates multiplying the maximum number of stitches up to which the automatic device can count, or, in the alternative, allows for both the number of stitches and the numbers of rows of stitches to be recorded.

Abstract: A chain stitch sewing machine is operated by two substantially parallel and horizontal levers, one of which is medially pivoted in the head and the other in the base. The levers are connected together by a link and actuated by a crank directly connected to the upper lever. The upper lever, which is slidable along its fulcrum to accommodate the throw of the crank, actuates the needle bar. The lower lever actuates a swingable hook by means of a cam secured to the hook and pivoted therewith in the base. A feed dog supported for vertical and horizontal movement in the base has a camming portion interposed between the cam and hook and which is also actuatable by the lower lever and by the cam.In a modification, the upper lever, which is of the first class, does not slide along its fulcrum axis. The actuating arm of the lever is laterally flexible, in a direction parallel to the fulcrum axis, but rigid in a plane perpendicular to such axis, and at its free end is directly pivoted to the crank.

Abstract: A machine for performing needlepoint or the like wherein successive loops of a single strand of yarn or the like are inserted through fabric, the machine including a carriage mounted for slidable movement in a given direction, the carriage having an indexable open framework roller mounted thereon, the roller being adapted to support a fabric for receiving the yarn. First and second members are pivotally mounted about a common axis within the machine, each of the members having arm portions extending toward the roller and adapted for insertion through the fabric carried thereby. The arm of the first member is configured in the shape of a needle having an eye adapted to receive the yarn therethrough, the needle arm being channel-shaped in cross section for selectively receiving the arm of the other member in abutting sliding relation, the free end of the arm of the second member being notched.

Abstract: A suturing device for sewing animal skin or flesh having a reversely movable arcuate needle and a pivotal rocker arm, said needle and rocker arm being movable in planes at substantially right angles to each other whereby said rocker arm affords a loop in the suturing thread for each succeeding stitch afforded by the needle. When operating, the device includes a continually operating electric motor having clutch means for engaging and disengaging, as desired, a drive shaft and a driven shaft, the latter affording pivotal movement to the needle by means of an extension on the driven shaft which alternately engages drive elements on a pivotal shaft which is attached to the needle. The rocker arm is driven by the driven shaft by engagement of lugs on the driven shaft and a rocker arm shaft parallel thereto.

Abstract: A hand-held single-thread lockstitch sewing machine or stitcher for attaching buttons, snaps, bar tacks, or the like, employs a boat-type shuttle for capturing the loop thrown by the needle. A limited length of bottom thread is stored by manually positioning a lever which directs the loop over a finger-like projection in the shuttle to trap the loop. Repositioning the lever will allow the machine to sew normally with the loop passing around the shuttle and picking up the stored thread. Bottom tension is applied by magnetically attracting the shuttle to the carrier wall and passing the bottom thread between the shuttle and the carrier wall.
