GENERAL REPORT OF THE JUDGES OF GROUP XXII. 25 trie on the main shaft, the eccentric vibrating the vertical lever, and it, in turn, vibrating the shuttle-carrying lever. The usual four-mo tioned feeding-bar derives its up-and-down motion from a push-rod connected with the vibrating shuttle-moving arm, and its forward movement from an angular lever, connected with a feed-lever, operated by a vertically reciprocating feed-connecting rod, and lowered by an eccentric on the main shaft. The end of the feeding lever is provided with an adjustable screw, which may be caused to extend a greater or less distance below it, so as to be engaged sooner or later by the feed-connecting rod to lengthen or shorten the stitch. The feeding lever and feed are moved in one direction by a spiral spring. The angular lever engages the end of the pushing-rod after it is projected through the feed-bar. The machine intended to sew leather had a wheel-feed and a rolling presser, and a device at the top of the head to control the needle-thread. The Grover & Baker machine is too well known to need descrip tion, further than to say that the stitch made by it is formed from two threads taken directly from two spools. One thread is carried by a curved perforating needle at the end of a vibrating arm, and the other (the under thread) is carried by a rotary reciprocating eye-pointed looper at the top of a vertically placed rotary reciprocating shaft. For bag work the stitch made by this machine has no equal. Silk being used below, it is also excellent for embroidering purposes. The Remington Sewing-Machine Co., Iliou, N Y. In the Remington shuttle-machine the straight needle and needle- bar were operated by a heart-cam. The main upper shaft was provided with an eccentric, connected by a link with an arm upon a rock-shaft below the cloth-support, it having at its forward end a crank con nected by a link with a shuttle-carrier. The shuttle was moved par allel with the feed. A second eccentric on the main rotating shaft operated a link connected with a second link placed in a horizontal position, and attached to the arm of a rock-shaft provided at its other end with an arm, connected with and adapted to reciprocate the four- motioned feed-slide or bar horizontally. A cam at the end of the shuttle-moving shaft struck one end of a two-armed sleeve, placed loosely upon the rocking shaft of the feed-mover, and the other arm, provided with an adjustable screw, acted upon an adjustable shoe or block on which the feed-slide was supported, and lifted the feed, a spring moving the feed back and down. The thread-controlling lever was placed on a short stud extending through the face-plate, and within the head of the machine it was provided with a V-shaped fork,
