WATERQGAG E.

SPECIFICATION forming part of Letters Patent No. 333,046, dated December 22, 1885.

Application filed March 27, 1885.

T0 (LZZ whom it may concern:

Be it known that I, WILLIAM YOUNG, of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and Improved VVater-Gage for SteamGenerators, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a broken side elevation of my new and improved water-gage; and Fig. 2 is a sectional plan view of the same, taken on the line a: 00 of Fig. 1.

My invention consists of a watergage having an inner and outer glass tube, whereby sudden changes of temperature will not break the glass tube, as it is liable to do with the gages of ordinary construction.-

Referring to the drawings, A B represent the upper and lower globe-valves by which the water-gage is connected to the boiler.

G is the inner, and D the outer, glass. tube. The inner tube, 0, is connected at its ends to the globe-valves A B by the elbows E, short pipes F, and coupling-nuts G, the ends of the tube 0 being connected to the elbows by the stuffing-boxes H. The stuffing-boxes H are each cupped ,as shown at h,to receive the ends of the outer tube, D, where they are held by the surrounding stuffing-boxes or packed nuts J, screwed upon the outer surfaces of the boxes Serial No. 160,334. (No model.)

H.- An opening, i, is formed in the stuffingbox H, to admit a slight circulation of air to contents of the tube 0, so that the condition.

of the boiler'may be easily and more accurately ascertained than with ordinary single glass gages.

Having thus described my invention,l claim as newand desire to secure by Letters Patent- 1. A water-gage consisting of two concentric glass tubes, 0 D, having a space, j, between them, the inner one, 0, communicating only with the steam-passages, substantially as herein shown and described.

2. In a water-gage, the boxes H, for securing the inner tube to the elbows E, formed with cups h, in combination with the outer tube, D,and nuts J, arranged substantially as and for the purposes set forth.

WILLIAM YOUNG.
