    Newton's Impts. in the Carbonization of Coal for the Manufacture of Gas, <SfC. respects the beam, as the means indicated consists in changing, by the play of the beam, the centre of gravity of the counterweight or counterweights G1 and F4. The piece S is intended to limit the course of the beam F, by adapting thereto two stop rods. I is a small shaft passing to the outside of the appa- 5 ratus through the stuffing box I3, and worked by the crank I4. In the middle of this shaft is a fork I1, which is capable of being brought into contact with the spindle I11 affixed to the beam. The object of this arrangement is by the rotatory movement of the shaft to raise by the action of the fork I1 and the spindle I11 that end of the beam, and with it the valve, and allow the free jo passage of the gas. It will be understood from the above description and Drawings that the gas enters the upper chamber M through the pipe A, from thence it passes through by the valve way to the chamber K1, whence it makes its escape through the pipe B. The opening of the valve is dependant upon the movement of the 15 beam, and the influence of the counterweight or counterweights, the action of which is to raise the float E, and consequently the gas contained in the chamber K1 is submitted to a given pressure, under which it flows out. Should this pressure tend to diminish, the float will by rising open the valve and allow an increased quantity of gas to pass. If, on the contrary, the consumption of 20 ^e gas is less than the supply through the valves TI, the pressure, by increasing above the float, will cause the valve to descend and diminish the area of the exit aperture for the passage of the gas. It will also be understood that the greater the extent to which the valve is open the greater will be the pressure of the gas above the float, as the beam 25 by its movement increases the relative power of the counterweight or counter¬ weights, by displacing the centre of gravity of these latter, which arrangement allows of the application of progressive pressure to the flow of gas. Having now described this Invention, and the best means with which I am acquainted for carrying the same into effect, I desire it to be understood that 30 I do not intend to confine myself rigidly to the details above given, as they may be variously modified without departing from the nature of the Invention. I would also observe that although, in order that the various improvements of which the present Invention consists may be more clearly understood, I have thought it necessary to explain in detail various parts which may have been 35 before known and in use, yet I do not by any means intend to claim them as forming part of the present Invention, except when they are combined and arranged in the manner herein-before set forth ; but that which I consider to be new, and therefore desire to claim as the Invention secured to me under the
