UNITED STATES PATENT OFFICE.

IIENRY G` BROOKS, OF BATTLE CREEK, MICHIGAN.

WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 442,010, dated December 2, 1890.

Application filed .Tuly 2, 1890. Serial No. 357,467. (No model.)

To all whom it may concern:

Be it known that I, IIENRY G. BROOKS, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, vhave invented a new and useful Improvement in Sight-Glasses, of which the following is a specification.

My invention relates to improvements in sight-glasses which are used to reveal the amount of waterin steam-boilers; and the objects are, first, to provide a device which can he adjusted to the requirements of any length of transparent tubes; second, to provide means whereby two or more pieces of tubing can be joined so as to form a substitute for one long piece, and, third, to improve the seating of such tubes, whereby additional security against leakage and entirely preventing the wearing away of the tubes by the ao tion of the steam and water. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a front elevation of my sightglass. Fig. 2 is a vertical section, and Fig. 3 a horizontal section through .r ai. Figs. I and 5 are vertical sections of the joining or splice bar B; Fig. 6, a vertical section atgj; Fig. 7, a perspective view of my improved gasket;

Fig. 8, a sectional view of my improved seating and gasket combined with the ordinary'r stuffing-box.

Similar letters refer to several views.

In Fig. l the cocks 71; and 7e are in pipes connecting with the boiler in the usual way.

G is a cylindrical chamber provided with a stul'ng-box (Z at its lower end,throu gh which a hollow rod Z1 extends nearly to its upper end. The lower or protruding end of said hollow rod is provided with my improved seating for the glass tube A, which will be hereinafter more fully described. f

The clamping-bar I, which surrounds the piston, is shown in section in Figs. 2 and 3, in which it' are screws butting against circular foot-pieces o o, which embrace the hollow rod b. The hand-nut c turns on a threaded extension c of the bar I, and is made to butt against the stuffing-box d. The protectingrods n n serve also to hold the joining-bar B similar parts in the the glass tubes are, first, the inner tube B',

The elements of the seatings of.

(shown in section in Figs. 4, 5, G, and 8,) and, second, the gasket, Fig. 7, and m, in the several views, which is composed of suitable elastic material, tubularin form, being thin at its upper edge and increasing in thickness toward the flange at its base. Said gasket is composed, essentially, of two parts: first, the upper conical portion m", operating as a packing between the inner cone B and the glass tube, and, second, the flange m at its base, which forms a seating for the ends of the glass tubes. It will be seen that by this seating the wear caused by the action of the steam and water is prevented. The ordinary stutiingbox may be used with this seating for additional security against leakage, as shown in Fig. S. The joining or splice bar B, used only when two or more sections are employed, as when a tube is broken, (shown in section in Fig. 5,) is provided with the seatings described,as is also the bar H, which may be attached to the cock h', or be made as a part of it.

To set a glass of two sections, put the lower section A in position upon Il and adjust the joining-bar B. In a like manner place the upper section A in position and bring the hollow piston down upon it, pressing all its joints firmly together. Adjust the clampingbar I so that the hand-nut c abuts against the stuffing-box d, clamp it securely in this position to the piston D by means of the screwst' t' abutting against the embracing foot-pieces o 0, when by turning the hand-nut c, abutting against the stuffing-box d, the piston is forced still farther down and the tubes are firmly seated in the elastic material of the gaskets.

I have thus far referred only to sightglasses for steam-boilers, for the reason that some of its parts are especially adapted to such useviz., that which protects the ends of the glass tubes from the action of the steam and waterwhile in general it is equally as well adapted to many forms of lubricat-ors now in use.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is*

l. The cylindrical chamber G, provided with the stuffing-box d, the hollow rod b, and the clamping-bar I, carrying the hand-nut c, in combination with the glass tube of a sightglass, substantall y as and for the purpose specified.

2. The cylindrical chamber G,vl1aving the stuffing-box (Lt-lle hollow piston b, the clampilrbar I, carrying the hand-nut c, au d the joi 11- ng-bar B, in combination with the glass tubes of a sight-glass, all substantially as set forth.

The clam ping-bar l, having the set-screws 1', circular foot-pieces o o, threaded extension c', and hand-nut c, in combination with the hollow pistou b, stuffing-box d, chamber (r, and glass tube of a sightglass, substantially as set forth.
