Abstract: “BELT TENSIONER WITH HIGH DAMPING RUBBER DEVICE”, the present invention refers to the technical field of belt tensioners in general, more specifically a belt tensioner (1) with high damping and with a rubber device (2), designed to generate higher rigidity and high damping to belts in combustion engines. The object of the tensioner is to reduce manufacturing costs, wearing and noise, both of the tensioner itself and the belt.
Abstract: An attachment for a sewing machine includes a lever which is provided with a hole to receive a screw of a needle-bar and is rotatably supported by a lever stand arranged to be shifted upward and downward upon operation of the needle-bar. The lever stand pivotably supports a ratchet wheel and a connector plate at the upper end thereof and has a forked holder at another end thereof. A guide plate is provided with a feed plate therebeneath and is pivotably fastened to the connector plate and shiftably arranged on one side of the lever stand. A ratchet gear feed plate is provided with a ratchet pawl which is engagable with a tooth of the ratchet wheel to be rotated in a predetermined direction. The guide plate is further provided with a projection at one end thereof, the projection being engagable with a pin positioned on one side of the lever stand to stop further shifting of the guide plate.
Abstract: A loading apparatus for an automatic sewing machine which includes a setting device for setting thereon a lower workpiece, a shirring plate hinge to the setting device, and a work holder having an upper blade and a lower blade for holding the workpiece therebetween during the sewing operation. The shirring plate has forks for mounting thereon an upper workpiece. The upper blade has corresponding forks for engaging in the forks of the shirring plate. The setting device is movable relative to the work holder to transfer the workpiece to the work holder.
Abstract: A sewing machine for making ruffles and a ruffler attachment comprises a base, an upstanding standard mounted on the base, an overhanging arm mounted at one end thereof on the upper end of the standard, a head carried by the other end of the arm and including a reciprocating needle bar and a presser foot, feed means are carried by the base beneath the presser foot and cooperating therewith to feed the material being sewn, and drive means for the needle bar and the feed means. A ruffling mechanism comprises an auxiliary shaft having its opposite ends journaled in the standard and the head for oscillatory movement and disposed in parallel relation to the overhanging arm. An elongate member is mounted at the end of the auxiliary shaft adjacent the head for movement with the auxiliary shaft and extends downwardly and outwardly therefrom to its outer end which is disposed in front of the presser foot.
Abstract: A ruffler attachment for a sewing machine, the operation of which is synchronized with the main sewing machine driving mechanisms, and facilitates adjustment of the size of the ruffle, and the number of ruffles to be formed, is provided. The ruffler attachment is characterized by a stiffener blade disposed to permit a body material to be introduced thereunder into the sewing displacement position of the needle to effect sewing of the body material. A feeder is provided for feeding and guiding a trim material to be ruffled into contact with the stiffener blade. A ruffler blade is coordinately displaceable from a first position wherein the ruffler blade is in contact with the stiffener blade to a ruffle forming position proximate the needle sewing position.
