To aLZZ whom it mayconccrm Beit known that we, CALEB G. CoLLiNs, of"
'Si o which the invention appertains to make and use the same.
j j Our improvements, though applicable to -Bliding or gate valves for various uses, arede- "signed-more especially for use in connection 1,5 with vacuum apparatus used in transferring :.dredged or excavated spoil; and the invention consists inthe special construction and arrangement of parts herein set forth. f In the accompanying drawings, Figure l, is je- ,asectional elevation of one of ou r gate valves; Fig. 2, a 4sectional elevation take-n at right .angles to Fig. l.4 Fig. 3, is a central vertical A, section of the upper portion of one of our f gate valves showing the means for governing 2,5 the movement of the same. Fig. 4, is a transverse section upon plane of line y, y, Fig..3; Fig. 5, a similar view upon plane of lin'e '2, z, Fig.' 3,. Fig. 6, is a sectional detail illustrating the means for .keeping the valve rod and I5e packing freel from grit, dac.; Fig. A7, apartial section of the steam cylinder throttle-valve,
-and connections; Fig. 8, a sectional'view of the .throttle valve.
The valve consists of the sliding gate P,
A"3.5 guided by lugs p, resting between-parallelv ways g, q, formed inthe casing Q, of the valve, y which casing also-incloses the compartment Q', into which the gate P, is retracted when the valve is opened. v 4o The valve rod P', extends through suitable packing boxes p', and fr, into tlie steam cylinder R, where it has secured to it the piston g '-p. Extending beyond the piston the valve 5 'rod 1?', passes through the steam cylinder R, 4,5 A and through suitable packing boxes r,.and 35,150 and through a cylinder S, of nearly equal `vlength but of less diameter than the steam wcylinder R., The valve rod I, passes out-.of the Kupperend of -the cylinder S, through a 35oI `suitable 'packing S'. The cylinder S, is filledv witlio'il or other liquid which has to pass from one side to the otherof the pistons', secured to the valve stein P, and the speed of this ow ot' liquid regulates the speed with which the gate opens or closes under the lpressure of steam on the piston p3, in the steam cylinder R. In other words the necessary displacementof the liquid in the cylinder S, retards and controls theaction of the steam in the steam'cylinder R, in such manner that all jar and violence is avoided. It is thus obviousl ,that by regulating the iiow of the liquidin the cylinder from one side of the piston S', to the other we can govern accurately the speed of the. piston 1), rod l, and valve P, and we accomplish `this adjustment in a novel manner.
seen that the upper'end of the valve rod is hollow, forming a long. cylindrical chamber T, the lower end of which terminates in a conical valve seat tffrom which a narrow passage t', extelids downward a short distance to where it is intersected by lateral passages t2, opening into the liquid chamber S, below` the piston S. The valve rod l, Where it forms the wallsof the chamber T, is formed with perforations tits, shown in Figs. Li and 5, such openings being above the piston S. 'lhe 'valve consists of a long stem or rod U, the lower end of which is made conical to fit the valve seat' t, and the upper end of which is formed with a male screw thread which en- By reference toFigs. 3, 4, ande, it will be gages with a female screwthreadformed in x the hollowl upper extremity of the valvevrod. A jam nut V, screws upon the projecting end of the vvalve-stein U, and locks the required' adjustment of the conical end of the valve with relation to the valve seat t. By increas.-
ing or diminishing the space between the conical end of the valve stem U, and its seat v t, the iiow of the liquid vfrom one Aside of the piston to the other, under 4pressure exerted bythe action of the steam upon either side of the piston 293,'ixi'the steam cylinder-R, can beregulated with accuracy, and itis to be noted that this adjustmentcan be etected entirely from the -ex'fteriorofthe device by simply loosening the jainnut V, turning the' stem U, in' one direction o'r the other. by
v ineans of'a wrench or other deyice, andagaiu I' f setting up thel jam nut.
