a citizen of the United States, residing WALTER G. WERBEQK, OF CHICAGO, ILLINOIS WATER-GAGE rnorncron FORSTEAM-BOILERS.

To kill whom it may concern:

Be it known that I, WALTER G. WERBECK, at

- Chicago, inthe county of Cook'and State of Illinois, have invented certain new and useful Improvements in Water-Gage Protectors for Steam-Boilers, of which the following is a specification.

This invention relates to improvements in water gage protectors for steam boilers and it is adapted primarily for use upon marine boilers and stationary steam boilers. The fact that the water gages of steam boilers comprise a glass tube in communication with the boiler often'leads to serious accidents, in the use of gages of ordinary. construction, due to the bursting of the tube from ternal pressure and the projecting of fragments of glass along with steam and boiling water through the atmosphere. One of the objects of this invention is to avoid such accidents, and 1t consists of a sectional hinged glass-protector, open at each end, which encompasses the water tube and which is provided in its swinging section with removable strips ofa very hard glass through which the water level in the gage may be easily read; the relatively stationary section ofthe protector comprising a metallic back that may consist of a metallic blank whereon differently colored stripes are painted to enable a clear reading of the water level in the gage from a distance.

Another object is. to provide aprotector wherein the transparent glass strips can be readily cleaned and instantly removed when desired or necessary. I A further object is to provide a protector so constructed as to permit almost instantaneous insertion or removal of the gage glass, the only tool needed for this operation being an ordinary monkey wrench. While it is true that the danger of injury to those about a marine or stationary steam boiler due to the accidental breakage of a water glass is reduced on account of the usual height of the water glass from the ground in these cases, it is also true that bursting of such glasses has, in many cases, been known to take place immediately upon insertion of a new glass in position and this accident often results in the injury of the person or persons-engaged in installing the. glass. It is an ob'ect of this invention to ob- 'viate accidents 0 this'nature.

With the, foregoing and other objects in view the invention consists in the combina- Specification of Letters Patent.

part of said spe'ci cation and water gage protector showing its applica-' Like reference characters denote cor1e' sponding parts throughout the several views- Thereference numeral 1 denotes a steam boiler provided with the hand valves 2 and 3 which lead respectively to the steam and Extending toward each other and in alinement with each other are the nipples 4, 5 which carry the gage nuts 6, 7 .that carry the gage glass 8. My protector comprises a casing approximately cylindrical in shape and open at top and bottom and composed of a stationary section and a movableor door-like section.

The stationary section is a one-piece section and consists of a back 9 having two pairs of alined ears 10 and 11 through which the ends of the staples or U-shaped bails 12 pass, the

closed ends of said members encircling the valves 2, 3 to support the back 9 rigidly in position. The ends of the material composing the bails are threaded for engagement with the nuts 13 to afford means for rigidly IsJecuring the ears of the back to the said ails.

To the cars 10, 11 the swinging section or door-like member 14 is secured by removable pintles 15 and to open the door it is butv necessary to withdraw one pintle and per mit the section 14 to swing upon the remain-' ing one. The member 14 is formed with a plurality of apertures 16'each 'of which is closed by a removable-strip of hard glass 17 which is normally disposed in the recessed portions 18 of this member Through any of the glass strips 17 the hei ht of the water in the gage glass may be real ily observed.

Referring again to the back 9, the same may be formed of a solid blank of material which may be painted or colored in stripes as shown at 19 in Fig. i to form a reflector and facilitate the reading of the gage glass.

Vhat is claimed is 1. The combination With oppositely disposed nipples, of gage nuts, a gage glass connecting said gage nuts and readily releasable therefrom a sectional member comprising a stationary element and a movable element inclosing said gage glass, said stationary element having applied thereto a striped coating of light-reflecting material, said movable element being formed with longitudinal apertures and having glass strips normally closing said apertures, means for adjustably supporting said stationary element, and means for locking said first named means in adjusted position with relation to said stationary element.

2. The combination Wlth oppositely disposed nipples, of gage nuts, a gage glass cona meeting said gage nuts and readily releasable therefrom, a sectional member comprising a stationary element and a movable element in closing said gage glass, said stationary element having applied thereto a striped coating of light-reflectingmaterial, said movable element being formed with longitudinal apertures and having removable glass strips normally closing said apertures, threaded bails adjustably supporting said stationary element and nuts for the threaded portions of said bails for locking them in adjusted position With relation to said stationary element.

In testimony that I claim-the foregoing as my own I have hereto aflixed my signature in the presence of two subscribing witnesses.
