15mm Patent No, 73,450, amd-January 21, 186s.
dite ttgehulr referrer tu in tigen etters ntentrnt marking part nf ttt sume.-
Y Be it known that I, CALVIN KLINE, of Broo/klyn, in thecounty of Kings, in the State of New York, have invented certain new and useful Improvements in the Stuihng-Box or Tight Joints adapted for revolving or partially-revolving stems or shafts; and I do hereby declare that the following is a full and exa'ct description thereof.
'I will first describe what I'consider the best means of carrying out my invention, and will afterwards desig" nate the points which I believe to he new therein. The accompanying drawings form a part of this specification.
Figure 1 is a side elevation, and Figure 2'is a longitudinal vertical section through the same. Similar letters of reference indicatelike parts in all the figures. The material of the whole may bev iron and steel.
A'is the upper portion ofthe casing of a steamstop-valve or other structure, in which it is .desiredto operate a valve or other part, B, by turning a screw, b, the threads of which run in afcorresponding female screw, a', as represented. The head of the screw b is vprovided with a deep,"square socket, as representedhy b. To operato the valve B, it is necessary to turn the part b, and in turning the latter it traverses axially up down, as will' be-obvious. C is a'hand-whecl, by turning which in opposite directions the valve 4B is to be operated. It is connected by a. stem, c, which is furnished with a square tenon, c', which notches into the square socket'b, and allows suicieutspace for the socketed part to traverse up and. down as far as may be necessary without-losing its connection. C is a collar, formed on :the stem c,`and accurately finished on its upper surface. I make this upper surfaceconical or concave, as represented, with a concavity on the upper surfaceof the cap E, to contain oil for lubricating, The lower face of this collarC/.is also smoothly finished.
-I prefer to make this surface plain. Dis a spring, made by simply curvinga washer of steel. It'lies between i adjustment. The necessity for any such soft packing is obvia the under sido of the collar C. But this only has the eiiect to press the rubbi ations where a shaft o`r stem is rotated, or partially rotated, without requiring any p the lower face of the Vcollar C "and theupper end of the part A'. This spring need have but a short extent of motion, but must he suiicicnt to allow for the wear of' the surfaces, and acts with a constant force, pressing the collar C up against a corresponding accurately-finished surface'on the cap-piece E. Thisap-piece is screwed upon the upper end of Vthe top-piece A', which is secured as represented, upon the part A, and is easily madeto t steam-tight thereon. The only place which it is ditiicnlt to make steam-tight is the joint around the revolving stem c. This must necessarily. tit loosely, or easily, to allow it to be turned with facility, and as these parts are ordinarily made, soft packing-is employed lfor the purpose, which requires frequent attention and ted by my invention, because the springD presses the accurately-finished upper surface of the collar C against the nicely-finished corresponding surface of cap E. The slight wear of these surfaces is taken u-p by is always maintained.
Whenever-a pressure of steam or other fluid exists within the casing A, itis' liable to he experienced on ng surfaces the more tightly into contact, and my stuHing-box, by which name I prefer to term it, although there is no stuiiing properly so called employed, will serve for a very long period, without any necessity for adjustment or other attention.
I can employ any of the materials, such as brass or steam-metal', which are adapted for these kinds of surfaces. It may be preferable in most cases to make the-'cap E and stem c of such material, in order to avoid the possibility of rusting. i
Stuing-boxes analogous to mine have been proposed and patented, in which a spiral spring, mounted above the tight part, was introduced to perform the function of my spring D. Myimproved construction and arrangement are preferable, for the -reason that the tight part of mine can he convenientlylubricated, whileA the other cannot, and that my spring D never changes its tension by any tendency to wind and unwind by turning the stem, while thc other is seriously objectionable on this account. j
A portion of my invention is adapted to operate on rolling valves, rotary steamengines, and the like situ'- revision for .the traversing of one/part endwise 'relatively to the other.' I such cases the socket and tenon bc may be dispensed with, and
the extension of the spring D, and a steam-tight contact the stem c, or an equivalent part, may be extended directly through. But `in order to adapt my invention to the working of screw-vulves, and those frequently-recurring uses where one part must move endwise, my tenen and socket, or some equivalent provision, is necessary. The square form of my tenon :md socket is not essential.
Any form of sleeve which allows the parts to move cndwise upon each other, while compelling them to turn `togetlier, will answer the purpose.
Having now fully described my invention, and indicated what I consider the best means of putting it in Ipractice, what I claim es new, und desire to secure by Letters Patent, is as follows:
' I claim'the collar C', on the rotating or partially-rotating stem c, arrangedas represented relatively to' the 'easing A, spring D, und cap E, so us to allow'of lubrication, 'all as und for the purposes herein setforth..
