Description
and use the same, I will proceed to describe NITEE STATES JOHN JACOB MILLER, OF CHICAGO, ILLINOIS, ASSIGNOR TO HIMSELF AND ERNST PRUSSING.
IMPROVEMENT IN VALVES FOR STEAM-ENGINES.
Specification forming part of Letters Patent No. 43,949, dated August 23, 1864 antedated February To all whom it may concern:
Beit known that I, JOHN JACOB MILLER, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Valves; and I do hereby declare the following to be a full and exact description of the same, refcrencebeing had to the 'accompanying drawings, making part of this specification, in Which- Figure l is an axial section of a valve illustrating my invention. Fig. 2 is a horizontal section at x sv, Fig. 1.
Similar letters of reference indicate corresponding parts in both figures.
My said invention consists in the use of a stationary cylindrical seat inclosed by a cylindrical valve adjustable in the length of its stroke, as hereinafter explained.
The invention further consists in an iniprovcd device for :regulating the stroke of the valve.
To enable others skilled in the art to which my invention appertains to fully understand its construction and operation.
A is a stationary cylindrical valve-seat, closed at its upper end, and near that end provided with a number of slots or apertures, a a, for the passage of the fluid. The said seat projects axially upward within a cast cylindrical casing, B, which is closed at its lower end by the base ofthe seat A, and at its upper end by a head, C, provided with a stuff ing-box, c, through whichy works the valverod, to be hereinafter described. The casing B has a port, b, constructed and located in any suitable way.
l) is a cylindrical valve fitted around the seat A and connected by a yoke, E, to a valve-rod, F, which Works through the stuft ing'box c, as before stattd. The said valverod is screw-threaded for a considerable distance at its upper end, and formed with a longitudinal sleuf, the purposes of which will be presently explained.
G is a hand-wheel formed with an elongated hub, which is threaded upon the valverod.
H is a cross-head swiveled up the hub of the wheel G, and there retained'by a nut, I.
J is a spring secured to the under face of the wheel G. 1
K is a pin projecting inward from the spring J The said pin may pass through an aperture, g, in the hub and into the longitudinal slotfin the valve-rod, as shown in Fig. 1, to secure the wheel from turning; or it may rest in a notch, g, in the hubwhen the wheelis to be turned up or down.
Operation In using the invention, the arm, beam, or rod by which the valve is to be operated, is attached to the arms h of the head H. The apertures c in the valve-seat are opened by the descent of the valveand closed by its as cent. To regulate the extent to which the valve will descend, and thereby the area to which the said apertures will be opened at each stroke, the spring J is drawn out, and its pin K rested in the notch g'. The wheel G may then be turned up or down, carrying with it the cross-head H. The higher the cross-head is set upon the valve the lower the valve will descend at each stroke, and vice versa. In this way the motion of the vvalve can be adjusted as desired, and' being set to effect the required length of stroke, it is so held by setting the pin K through the aperture g into the slot j', by which means the wheel G is locked upon the valve-rod.
The packing of the stuffing-box c and valve D may be constructed in the manner described in my application of even date herewith for Letters Patent for improvement in p steam and other packing, the regulatingscrews being supplied in one case by the customary screwsleeve, cf, and in the other case valve to regulate the iioyv of steam,vvater, and' other fluids in any manner and place in which it may be found applicable.
Having thus described my invention, what I claim therein as new, and desire to secure by Letters Patent, is
1. The combination of the fixed cylindrical seat A and cylindrical valve D with an adjusting-wheel G, or other substantially-equivalent device, to regulate the effective stroke of the said valve, as explained.
2. The spring J and pin K, used in the described combination with the aperture g in the wheel G, and the slot f in the valve-rod F, to lock the said Wheel to the said rod or permit it to be turned up or down thereon, as and for the purpose explained.
Witnesses: JOHN JACOB MILLER.
JOHN G. SHoE'rALL, HENRY FULLER.
