113' plieation filed September 17, 1915.

To aZZ ct /tom it may concern Be it known that we, WILLIAM A. HARD- WICK and Janus T. ERADLEY, citizens of the United States, residing at Memphis, in the county of Shelby, State of Tennessee, have invented a new and useful ater-Gage Glass, of which the following is a specification.

The device forming the subject matter of this application is a water gage, and one object of the invention is to provide a device of this type in which ordinary glass water tubes may be dispensed with.

Another object of the invention is to improve the construction of the transparent element by strengthening the same and by so constructing it that the water level may be readily visible.

Another object of the invention is to provide a structure of the sort above mentioned which may be adjusted circumferentially, without breaking the continuity of the water conduit.

. It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view wnich will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter descrlbed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of what is claimed, without departing from the spirit of the invention.

in the accompanying drawing :F igure .1 shows one form oi the invention in elevation, assembled with the water column of a boiler; Fig. :2 shows in longitudinal section the glass structure forming the subject matter of this invention as delineated in Fig. 1; Fig. 3 is a cross section taken on the line 3 3 of Fig. 2.

In carrying out the present invention ,there is provided a body 1 preferably made of metal and equipped at its ends with openings 2. Within the contour of the body 1 there is formed a longitudinal channel 8. The channel 3 serves to define, in the body 1, end walls at in which the openings 2 are located. The side walls of the channel 3 converge as they extend rearwardly, as indicated at ii in Fig. 3, the base or back of the channel being rounded as shown at 6. v

seriai no. 51,225.

The rounded back or base 6 of the channel 3' is alined with the perimeters of the openings 2 throughout a portion of the circumference of the openings, .so that there is a straight and direct conduit through the body, from one end thereof to the other. The body 1 is provided with a depressed seat 7 in which is located a gasket 8. Disposed within the seat 7 and resting against the gasket 8 is a transparent member 9 which may be fashioned from glass. The outer faces 10 of the transparent member 9 diverge as they extend rearwardly, the side walls of the transparent'member being disposed in parallelism and the rear wall 12 of the transparent member being disposed at right angles to the side walls 11. The rear wall 12 of the transparent member 9 is provided with a plurality of longitudinally extended corrugations 14. Owing to the fact that the rear wall 12 of the transparent member 9 is supplied with the-longitudinal corrugations 14:, and owing to the fact that the walls 10 of the transparent member diverge as they extend rearwardly the Water level may be ascertained readily at a glance,

, irrespective of the position of the observer and irrespective of a rotation which, as hereinafter described, may be imparted to the body 1 for the purpose of adjustment.

Abutting against the rearwardly diverging faces 10 of the transparent member 9 is a gasket 15 and superposed upon the gasket 15' is a cap 16 having an opening 17 through which the transparent member 9 protrudes, and including end strips 18 which, coiiperatin g with the ends of the transparent member 9 prevent the same from moving endwise. The inner edges of the cap 16 are beveled as indicated at 19 to assume approximate parallelism with the adjacent walls 10 of the transparent member 9, the beveled faces 19 of the cap lying against the gasket 15. Securing elements of any desired sort, preferably machine screws, indicated by the reference character 20, unite the cap 16 to the body 1.

Threaded or otherwise secured in the openings 2 of the body 1 are nipples 21, coacting, as shown in Fig. 2, with the necks 22 of valve casings 23 carrying valves 24:. Nuts 25 are threaded onto the necks 22 and areprovided with inwardly extended flanges 2-6. interposed between the flanges 26 and the necks :22 of the valve casings 23 are packing whiskers The valve casings 23 are connected with tubes 28 which, in their turn open into the boiler water column 29, proi'ided with the usual openings 30 adapted to receive gage cocks (not shown).

It is to be observed that, at any time, the nuts may be loosened, permitting a circumferential adjustment of the body 1 and i the transparent member carried thereby, the

In a device of the class described, a body As hereinbefore stated, the

having inlet and outlet openings communieating with the channel; a transparent member including a flat rear face cooperating with the shoulder, side faces cooperating with the marginal flange and disposed at right angles to the rear face, and front faces which converge to form an edge; a frame surrounding the transparent member and including beveled faces coacting with the" front faces independently of the side faces; and means for securing the frame to the flange.

In testimony that we claim the foregoir r as our own, we have hereto ailixed our sig natures in the presence of two witnesses.
