ADJUSTING AND SECURING SL IDE-VALVES UPON THEIR RODS.

SPECIFICATION forming part of Letters Patent No. 301,416, dated July l, 1884.

Application led J anu To all whom v5 `may"concern.:

Be it known that I, VILLIAM E. WILEY, of the city of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful device for tightening, adjusting, and firmly securing slide-valves upon their rods without opening the steam-chest, which invention is 'fully set forth in the following specification, reference being had to the accompanying drawings.

The object of my invention is to tighten, adjust, and firmly secure the valve-rod of a slidevalve engine to the valveby means of cylindrical sleeves or tubes combined with screw-nuts,

which latter are outside of the steam-chest, .without opening the steain-chest.

The invention is illustrated more in detail by the accompanying drawings.

Figure 1 isa vertical section ofFig. 2 with steam-chest. Fig. 2 is a plan view of the invention with steam-chest removed.

Similarletters refer to similar parts throughout the several views. Y

A is a following-nut, which is used in holding the nut .I firmly in position. B and B are beveled joints. C and C are elongated cylinders or tubes, made of brass, steel, or Wroughtiron, through which passes the valve-rod G. D, and D are stuffing-boxes. E the steamchest. F and F' are lugs of the valve H. G is the valve-rod. H is the valve. J is a tightening-nut, by means of which the cylinders C and C are permitted to slide along the valve-rod G. K-is a similar nut. H is an ordinary valve having lugs F and F', so arranged as to permit the valve-rod G to pass loosely between them. The cylinders or tubes C and C' it loosely on the valve-rod G, and are pressed become loose on the valve-rod G, it `may be adjusted to any position lfrena without the steam-chest E, thus preventing the necessity ary 17, 1884. (No model.)

of taking off the cover of the steanrchest E, as is required, where grip-collars are used inside the steam-chest- I claim as my invention and desire to secure by Letters Patentl. The combination, with a steam-chest, a valve-rod, and valve adjustable thereon, of sleeves .for clamping the valveA on opposite sides, and'nuts located outside of the chest for" moving said sleeves, whereby the valve may be adjusted from the outside of the chest back and forth onthe rod and tightened and locked to the rod, substantially as described.

2. VThe combination, with. a steam-chest, a valve-rod, and valve adjustable thereon, of sleeves having enlarged ends bearing against opposite sides of the valve, and nuts located outside of the chest for moving said sleeves, whereby the valve may, from the outside of the chest, be adjusted back ,and forth on the rod and tightened and locked to the rod, substantially ,as described.

3. The combination of the steam-chest, the slide-valve formed with lugs With a space between them for the passage of the valve-rod, the rod, the sleeves encircling the rod with one end bearing against the lugs on the valve and the 'other end extending outside of the chest, and thescreW-nuts engaging with screwthreads on the rod and bearing against the said sleeves, whereby the valve may, from the outside of the chest,bc adjusted back and `forth on the rod and tightened and locked to the rod, substantially as described.

4. VThecombination, with a steam-chest, a valpve-rod,andv valve adjustable thereon, of clamps on opposite sides of the valve operated from the outside of the chest to move the valve back and forth on the rod and tighten it and lock it to therod, substantially as described.
