KAEFER'S MODE OF TRANSMITTING MOTION.
The accompanying engraving represents a bench in which are combined a circular saw, a scroll saw, a border, and a mortising-machine; each arranged so as to be readily removed out of the way, and all worked by one treadle, In combination with a peculiar fly-wheel, for which Letters Patent were granted in the United States to Mathaus Kaefer, of New York City, May 5, 1857 (#17,222), and May 31, 1859 (#24,218). Patents have also been secured in Great Britain.
S represents the circular saw; and », the scroll saw, B, the borer, and M, the mortising-machine. By loosening the apt-screw, a, the circular saw may be let down below the upper surface of the bench, the borer turns down by a similar arrangement, the scroll saw, s, may be easily unrigged and removed, and the mortising machine may be thrown out of gear by pressing on the end of the rod, n, or it may be entirely removed from the bench by loosening the thumb screws with which it is fastened. The axle on which the fly-wheel, F, runs, passes through journal boxes which slide up and down in the frame, and its end is seen in the center of the wheel, w. The rod, r, is connected at one end by a loose pin with one edge of the wheel, w, and at the other end to the frame of the machine. Thus, when the journal boxes are pushed up by the treadle, the wheel is both raised and turned, and motion is then imparted to the machinery. By this arrangement, the fly-wheel has not only a rotary but also a vertical, reciprocating motion, combining the action of the fly-wheel with that of the pile-driver or hammer. If, where the resistance is variable, the parts are so adjusted as that the wheel with its journal boxes, shall be coming down at the time of the greatest resistance, as when the chisel is cutting the wood, for instance, it will concentrate the power more perfectly on the point of resistance than will a fly-wheel of the same weight, running on a stationary axle.
These machines are made by the Kaefer Power Company, at room 26, in the large building of the Harlem Railroad Company, corner of Franklin and Elm streets, New York. For further particulars address the company as above. |
