PATENTS RECENTLY ENROLLED. RECIPROCATING ACTION FROM A ROTATORY MOTION.-William Parr, of the City-road, and James Bluett, of Blackwall, Middlesex, ship-joiner, have patented “a new method of producing a reciprocating action by means of a rotatory motion to be applied to the working of all kinds of pumps, or other machinery, in or to which reciprocating action is required or may be applied." Such is the title which the patentees have prefixed to their invention, which consists in two pinions placed on the same axis ; só connected with it and each other by locking pins, that one of the pinions are caused to turn with the axis, while the otber is permitted to run loosely upon it, and this they do alternately. These pinions are placed within a reciprocating frame, furnished with two racks, the one placed to be acted upon by the right side of one of the pinions when it is locked to the axis, and thus cause the frame to advance, and the other to be acted upon by the left side of the other pinion, while it is locked to the axis, and the first per:nitted to run freely, and thus cause the frame to retreat again. When the reciprocating frame has advanced to its greatest extent, it acts upon the locking geer, which releases the first, while it attaches the second pinion to the axis. It will be perceived that the rack on one side must be placed the thickness of the pinion more forward than the rack on VOL. IV.--NO, 53.
