For reading or memorizing a pattern perforated in rows in a card, pattern-reading members having pointed ends in a row are successively fed from a first to an arbitrarily selectable last row of the irregular perforations making up the pattern. The thus memorized pattern is conveyed to needle-selecting members including pattern plates which have projections formed at constant spacings thereon. Some of the pattern plates associated with those of the pattern-reading members which correspond to the ...

An apparatus for joining together two pieces of work fabric or similar materials which comprises a first support for setting a first piece of work fabric and a second support for setting a second piece of work fabric and causes the edges of the first and second pieces to be superposed one on the other by the movement of at least one of said supports so as to have said superposed edges later joined together by suitable joining means such as stitch forming means.

A sewing machine so designed as to cause an arm shaft to be subject to different drive controls according to the operating position of a selection knob, though a controller may be continuously depressed in the same manner, wherein, under the first operating position of the knob, the depression of the controller effects continuous normal stitching and the release of the controller brings the arm shaft to rest at a predetermined angular position; under the second operating position of the knob, th...

In a repeat spacing mechanism for typewriters, first and second wheels are rigidly mounted on a shaft rotatably engaged with a carriage in an axial direction. Generally, the wheel faces a pair of pawls rotatably mounted on a pawl shaft in a plane parallel with the rotating plane of these wheels and alternately engaged with or disengaged from the wheels. There is provided a weight at the lower end of the pawl shaft. Depression of a type key or space bar causes the pawls to be alternately engaged ...

A wig dryer comprising a blower-heater unit, a wig supporting block having an air chamber therein and apertures through which the air chamber communicates with the outside of the block, a telescopic flue assembly for connecting the air chamber with the blower-heater unit, a hood having the inner shell perforated with apertures and adapted to cover the wig supporting block, another telescopic flue assembly for connecting the air chamber provided in the hood with the blow-heater unit, wherein the ...

A lock stitch sewing machine concurrently capable of carrying out chain stitching, namely, performing lock stitching when fitted with a throat plate adapted for said stitching and chain stitching when provided with another throat plate suitable for said stitching.

An ornamental zigzag stitch sewing machine comprising zigzag pattern and feed controlling cams which respectively allow a needle to be laterally oscillated and a feed dog to be controlled in the length and direction of feed, the movements of the needle and feed dog being simultaneously adjusted by single manually operable means to produce ornamental zigzag patterns in various sizes similar to that of a base pattern.

A repeat spacing mechanism for typewriters, particularly manual typewriters, comprising an escapement mechanism including an escapement wheel and a pair of pawls cooperating therewith; and a repeat spacing key connected through a spring to a rockable lever having a weight attached to its free end and normally biased to an inoperable position to release the escapement mechanism, whereby, upon depression of the repeat spacing key, the lever is moved to an operable position by the spring to actuate...

A repeat typing mechanism for power operated typewriters comprising a snatch roll, pawl members detachably engaged therewith, actuating members rockable about a fixed shaft so as to hold said pawl members in a rockable state, key levers, and control levers actuated by said levers and provided with first and second bent lugs disposed substantially at right angles to each other, wherein the key lever can be successively depressed in two steps, and at the time of the first step depression of the ke...

A repeat spacing mechanism for typewriters wherein there are rotatably mounted a feed pawl and a hold pawl on a pawl shaft coaxially therewith; normally the hold pawl engages a toothed wheel rotatably urged by a spring drum for moving a carriage in the letter feed direction. Further provided is an elastic member made of piano wire which is operated by a repeat space key, said member being provided with a weight at its free end. During depression of the repeat space key, the elastic member acts o...
