4975. Denne, M. T. March 9. Ornamenting. -Relates to a stitch - separating and indenting machine, and consists of a mechanism for positively feeding the work forwards, by means of which the distance between the indentations can be regulated, and an auxiliary mechanism is also provided for slightly varying this distance to allow for stitches which are greater or less than the average. The work is held on a revoluble support i<2>, Fig. 1, attached to a guide - rod i<1>, which is arranged in a socket i formed in a sliding plate h, Figs. 1 and 5, mounted on a guide-plate h<1> on the head c of the machine. The support i<2> can be depressed against the action of a spring i<4>, which is supported by an arm i<5> of the head c, by means of a treadle connected to a rod i<6>. The edge of the sole is placed against an edgewheel k, and the work is further held in place, while the indenting- tool j<3> is in operation, by means of a presser-foot l. .The tool j<3> is operated by a double-armed lever j<3> mounted in the slide h and operated by a camgroove in a drum e, which is driven by mechanism comprising a friction clutch put into action by depression of a treadle against the action of a spring. The table i<1> is locked in position, to prevent it from being depressed while the tool is in operation, by means of a detent n moved by means of a sliding block n<1>, which is actuated by a bell-crank lever from a cam-groove in the drum e and causes the detent to engage a toothed wheel m<3> on a shaft to which is fixed a wheel m<1> engaging a rack m on the bar i<1>. The work is fed by a lateral movement being given to the slide h while the indenting-tool engages the work ; the extent of this movement is regulated according to the length of the stitches, which is ascertained by means of a gauge. The throw of the slide h is altered by adjustment of the position of a block q<1>, a pin q<2> on which engages a link connected to the slide h. The block g<1> slides in the slot q of a lever p oscillated by a cam-groove in the drum e, and is operated from a shaft s<1> through the rack and pinion shown in Fig. 5. A stitch gauge w is provided on the lever p. In order to increase or diminish slightly the distance between two indentations, to allow for the irregularities of the stitches, the position of the block q<1> can be varied slightly, during the operation of the machine, by means of a shaft t, Fig. 8, in alinement with the shaft s, Fig. 1, to which it is connected by a coupling and a set-screw after the position of the block q<1> has been adjusted. The shaft t can be rotated by a lever t<1> operated by the knee of the user, and this allows the distance between two indentations to be adjusted. A spring v returns the shaft t to its normal position.
