To aZZ Awhom it may concern.'

Be it known that il, EARNHARDT ZINDEL.. a citizen of the United States of America, and a resident of certain new and useful Improvements in lVaterGages, of which the following is a full and clear specification, reference being had to the accompanying drawings', in whichi l Q,

Figure l is a view partly in side elevation and partly in vertical section showing my 'improved gage applied to a steam boiler; FigQ is a side elevation of the main guard casing detachedg'Fig. 3 isa similar view of the guard frame or casing; Fig. 4C is a horizontal section on the line e of Fig. l, the parts being enlarged; and, Fig. 5 is a similar View on the line 5-5 of Fig. l.

rlhe object o i' this inventionis to so construct a glass water-gage that should the glass tube burst the steam and hot water and comminuted glass will be carried away by the pressure through a suitable waste pipe or tube, who may be near the glass from injury lby flying glass particles and hot steam, as more fully hereinafter set forth.

In the drawing, a designates the connection between the top of the gage and the boiler and Z9 designates the usual connection between the lower end of the gage and the boiler. The connection a is provided with a depending threaded nipple c and the connec- -5 tion Z2 is provided with an upstanding threaded nipple d. The usual glass tube e connects and extends into these nipples,rand surrounding this glass tube is the main guard traine or casing whose upper extre1non to the nipple c and whose lower extremity g is screwed on to the nipple aZ, the outer surfaces of these parts f and g being preferably adapted to receive a wrench for convenience in connecting up A suitable ,gasket/t is provided within the upper end of the casingand a similar gasket i' is provided at the lower end of the casing to make steam-tight joints at the 'respective ends of 0 the glass tube.

The vertical openings in the guard casing form a series of vertical'bars y' which surround the glass tube and form a guard cage therefor, and at the lower end of the casing,

5 at a point'just above the lower gasket i, the casing is provided with a series of lat- Green Bay,- ,county-ot 5 Brown, State of lVisconsin, have invented 'guard cage` or frame.

thereby protecting -persons glass tube become broken ber Z which at one side has cast integral with it a discharge elbow m to whose extreinitv is connected atube n. suitable point of deposit.

The annular'casing Z bears upon an annular shoulder 0 formed on the main guard casing, andthe top' wall 'of this casing has a bearing against an annular shoulder p formed on the 'guard easing at a point just above the openings Zi'. Projecting upwardly :trom the outer edge of the easing Z is an annular flange g which, together with the top Awall of the casing, forms an annular bearing Afor 'a gasket or packing r. Haring its lower end bearing upon this gasket fr is a supplemental glass tube s, and surrounding this tube s are vertical barsZ of a supplemental The lower ends of these bars are connected tits within the vupstanding flange y and bears down upon the packing r. Screwed on an externally threaded portion of the main guard casing7 at a point above the. termination of the bars j is an annular flange u which is provided with a depending flange to which surrounds the upper ends of the glass tubes s and a ring :i: connecting the upper ends ofthe bars t,-a suitable packing ring if being provided to make a steam and water tight jointat this point.

lt will be observed that while the gage is under pressure, the steam and water and small pieces of glass will be discharged out through the openings Z: and be conducted away by the pipe n. and the supplemental glass tube and guard bars will serv-e as temporary protection until the boiler is cut ott from the gage. It will be observed that under such conditions t-hel supplemental glass tube will not be subjected to the full pressure of the boiler` since the blow-oft casing and elbow and pipe are larger in area than the passages connecting the gage to the boiler, so that the supplemental glass tube willbe amply suh'icient to protect "surrounding persons .and objects until the gage can be cut oli" from the boiler. lt will be observed also that my construction greatlyY facilitates assembling of the` parts as well as dismantling of the structure. sothat the gage can be readily, put together and disassembled.

leading to a should the .main

Surrounding and inby a ring 'u which Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. In a water-gage, the combination of two boiler Connections, a main guard casing connesting the extremities of these connections, a main glass sight-tube inelosed within the casing, said casing being formed of vertical bars throughout the main portion of its length and provided with lateral openings at its lower end and also with an annular shoulder at its lower end below said openings, an annular blow-ofi' chamber surrounding the exits of said openings and bearing upon the said shoulder, an annular flange screwed on the upper end of said Casing above the upper extremities of the bars, and

- a supplemental sight-tube and guard frame therefor clamped between said annular flange and the upwardly facing top wall of said blow-oft' chamber.

Copies of this patent may be obtained for 2. The combination with boiler connections, of a -safety sight gage comprising a main guard casing connecting said boiler connections, a main sight tube inelosed therein, a blow-olf chamber supported on the main casing at the lower end thereof, said main casing being provided with an opening communicating with said blow-ofic chamber, a supplemental sight tube surrounding the main casing, and an annular flange adjustably mounted on the main casing and adapted. to clamp said supplementalsight tube against the blow-off easing, for the purposes set forth.

In testimony whereof I hereunto aiix my signature in the presence of two witnesses.4
