. Mechanical appliances, mechanical movements and novelties of construction; a complete work and a continuation, as a second volume, of the author's book entitled "Mechanical movements, powers and devices" ... including an explanatory chapter on the leading conceptions of perpetual motion existing during the past three centuries. e, but being held rigidly in the transverse direction,compels the file to accommodate itself laterally to the blade and so pre-sents its surface on the line of cut, truly parallel to the cutting edge ofthe chisel d. The chisel, d, delivers its blow under the impulse of a springin a casing, g, the spring being compressed at each stroke by the upwardmovement of the ram which is alternately lifted and let fall by a revolv-ing cam engaged by an arm h. Variation in the degree of compressionof the spring, so as to produce any desired graduation in the strength ofblow of the chisel, d, is brought about by increasing or diminishing theeffective radius of the cam to increase or diminution in the height of liftof the ram h. The cam is made tapering in the direction of its axis andis mounted upon its shaft with a groove and feather connection so as tobe longitudinally adjustable in order to bring any portion of its lengthto act upon the arm h. 801.
