Oberlin, OH |
"My invention relates to that class of machines used for cutting to a given length, and shaping or forming, the tenons on the ends of slats for window-blinds, and for inserting the staple therein; and it consists in the construction of the heads for holding the slat to be operated on; in the manner of presenting the work to the machine, so as to first saw off the ends, and then by rotating it against the cutters to form the pivots on its ends by a novel combination of devices; in the means for operating the staple-inserting mechanism automatically and in concert with said cutting and tenoning-mechanisms; in the peculiar construction of the feed-staple holder; and in the device for supporting the stuff against the lateral force of the staple-driver." |
