SAFETY-VALVE FOR BOLERS.
SPECIFICATION forming part of Letters Patent No. 569,670, dated October 20, 1896.
Application filed May 8, 1896, Serial No. 590,699. (No model.)
To @ZZ whom t may concern.-
Be it known that I, THOMAS PorrEnroN, a citizen of Great Britain, and a resident of London, in the county of Surrey, England,
steam-boilers, Water-boilers, and for general use in heating apparatus; and the object thereof is to provide an improved device of this class Which is simple in construction and operation and which is provided with a hollow spindle, with which is connected an escape valve or cock, by means of which the Water or steam can be drawn off when the cock is open, thus indicating the condition of the valve and Whether it is in operative condition.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure l is a side elevation of my improved safety-valve 5 Fig. 2, a central vertical section thereof; Fig. 3, a side elevation of a modified form of construction, and Fig. l a central vertical section thereof.
In the practice of my invention I provide a tubular head A, by which my improved valve may be connected with a boiler, hot-Water heater, or any similar device, and said tubular head is provided with an enlarged casing a, at the base of Whichis formed an annular chamber a2, in the bottom of which are formed blow-holes CL3, and said enlarged casing c is provided With a cap B, which is mounted thereon and connected therewith by means of a screw-thread, and passing centrally through said cap is a hollow spindle D, the lower end of which is provided with a port or opening` d and an annular shoulder or flange d2, below which is placed an annular cap d3, which is adapted to hold in place an annular packing-ring d4, which may be composed of vulcanite or any preferred material, and which constitutes a valve whichis adapted to be seated upon the upper end of the tubular head e as clearly shown in Fig. 2, and mounted on the hollow or tubular spindle D is a spiral spring E, one end of which bears upon the annular shoulder d2 and the other upon the cap B.
The cap B is provided with a valve-casing O, in which is placed a plug-valve G, and the valve-casing O is provided with a tubular connection II, Which is preferably curved, as shown, and through which Water or steam may be discharged, and the cap B is provided with an. annular flange or shoulder K, which is milled or otherwise roughened on the outer edge thereof, and which serves as means for connecting the cap with the casing a or detaching the same therefrom.
In Figs. 3 and 4 I have shown a modified form of this construction, in Which the hollow spindle D is providedat its upper end with a three-way head L, to one side of which lis secured the valve-casing C, with which is connected the pipe H, and the head L is pro vided at its upper side with an extension M, on which is mounted a plurality of Weights m, and the Weights m serve, as will be understood, in place of the spiral spring E.
It will be understood that in both forms of construction the tubular spindle D is free to move through the cap B, and, whenever desirable, the valve Gr may be turned so as to admit of the discharge of Water or steam, and when the valve is open if water escapes therefrom it Will indicate that the valve-seating is free from incrustation or ice, and if Water does not issue through the valve it will indicate that something is Wrong therewith, and said parts may be disconnected and examined.
This device is simple in construction and operation and perfectly adapted to accom plish the result for which it is intended, and I'reserve the right to make all such changes therein and modifications thereof as fairly come within the scope of the invention.
Ilavin g fully described my invention, I claim as new and desire to secure by Letters Patentl. The herein-described safety-valve which is provided with a vertically-movable hollow spindle, the upper end of which is provided with a valve or cock, and a discharge-pipe, substantially as shown and described.
IOO
2. rlhe herein-described safetywaylve which is provided with 'n vertically-moVahle hollow spindle, the upper end of which is provided with :L valve or eoek, and a discharge-pipe, said hollow spindle `being` mounted in a oasing at the lower end of which is i valve-seat, on 'which the lower end of the spindle is adapted to he seated, substantially as shown and described.
The herein-described safety-valve which is provided with a vertically-movable hollow spindle, the upper end of which is provided with a valve or Cock, and a diselmrge-pipe, said hollow spindle being` mounted in a easing at the lower end of which is :L valve-seat,
on which the lower end of the spindle s adapted to he seated, and said Spindle being` also provided with a spring which is mounied thereon within said casing, and which is adapted to force the same upon the valveseat, substantially as shown and described.
In testimony that I Claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 17th day of April, 1896. y
THOMAS POTTERTON.
