to provide a duplex column of the type wherein fiat plate glass is used for each columnfwhich is constructed so that both colpositions.

umns are disposed at a convenient angle whereby they may be viewed from different A column of this character is adapted especially for use upon locomotive boilers so as to permit both engineer and fireman to read the glass at all times.v

A further object of the invention is to provide a duplex column which is composed of the fewest'possible parts, and which is compact and durable so as to withstand the considerable jar incident 'with its use.

A still further object is the provision of a device of this character which constructed so that there is no danger, of either glass becoming blown out by excessive boiler pressure. v

The invention consists in the features of i construction, lcombination and arrangementof parts, hereinafter fully described and 4 claimed, reference being had tothe accompanying drawings, inwhieh:

Figure 1 is a front elevation of lthedevice; Fig. 2 is a rear elevation of the same;

Fig. 3 is a longitudinal sectional view taken through theY device; Fig. 4 is a transverse sectional view taken therethrough, and Fig.,l

5 is a transverse sectionala view of the body ofthe device alone. i

Referring' to the drawings, it will. be seen -that my improved duplex column comprises a body 1 whichl is formed with

wings

2 and 3 disposed, as shown, at right angles, but

which `may be disposed at any convenient angle. The body 1 is provided at 'its extremities with tubular portions 4f and 5 adapted to be connected to a boiler as shown, or in any other suitable well known manner. Each Awing of the body is provided in its outer face with a longitudinal recess '6. of rectangular configuration for the reception of a -portion of the corresponding gage glass 7, and is further provided with a longitudinally extending, semi-cylindrical groove 8 in its inwardly bulged ortion 9 in communication with the` sai recess `6. Each groove 8 extends for nearly the enti-re length of the corresponding recess, terminating at a short distance fromthe ends of the recess.

The longitudinalopening 10 of each tubuylar pbrtion of the body 1 is connected by means of the outwardly curved, branch passage-ways 11 with the adjacent ends of the respective wing grooves 8. The concave wall 12 of each branch passage-way 11 serves4 to retaird the motionjof the water as caused by excessive steam pressure, andfurther serves to direct the same against the gage glass 7 at rig-ht angles thereto and at a point substantially opposite the adjacent end por-V tion 13 of the corresponding clamping. memvwo ber 14,. so that undue strain will not come to bear upon the exposed portion thereof.

`Each clamping member letyis adapted to be secu-red against the outer face of one of the body wings by means of the clamping bolts 16, and completely covers the same, its end portions being rounded as at 17 to conform to the shape of the rounded ends of the wing. Each clamping member is cut away centrally as at 18 to providea longitudinal view opening in communication with the elongated recess 19 provided in the inner face of the said member for. the

reception of the outer portion of the coryopemngs 22 provided ingthe clamping member in communication with the extended recess portions 20,- inwardly with respect to the fulcrum edges 21, the inner ends of these. bolt-s being removably threaded into the re'- cesses 23 provided in the body wing. Nuts 24 arethreaded upon the outer ends of the bolts 16 and are engageablejwith the rounded outer face 25 of the clamping member, inwardly with respect to the ulcrum edges 21 thereof, so that, when the said nuts are tightened upon 4the said bolts, the. inner engaging edges or jaws 26 of the clamping member will be clamped against the asbestos gasket 27 interposed between the same and the outeredges of the gage glass. A

rubber gasket 28 is interposed between the inner edges of the gage glass and the inner Wall ofv the wing recess surrounding the corresponding Water groove. It is to be understood, that the metal of which the clampingmembers are constructed is to be of such nature that the inner clamping edges of the clamping member may be sprung inwardly wwhen the clamping members are tightened, and may be of brass, aluminum or the like.

From the foregoing description, taken in `connection with the accompanying drawings, it will be apparent that I have provided a simply constructed and emcient gage glass column of the duplex type which 'is adapted to meet all the requirements of usage, which will retain its respective gage glasses indefinitely and which may be used conveniently in connection with any type of boiler.

IVhat I claim is:

l. In .a'device of the class described, a

opening into the adjacent ends of the water grooves. f

2.`In a body having lateral Wings, provided in their outer faces with longitudinal gage glass recesses and with longitudinal Water grooves in the inner Wall of said recesses, and a tubular 'connecting portion provided upon veach end of said body having diverging,

outwardly curved `passage-Ways opening into the adjacent ends of the Water grooves.

8. In a device of the class described, a body having lateral Wings, provided in their outer faces with longitudinal gage glass re.

cesses and. with longitudinal water grooves in the inner Wall of said recesses, a tubular connecting portionprovided upon each end of said body having diverging passage-ways opening into the adjacent ends of the water grooves, a flat gage' glass adapted to be positioned Within each wing recess, and means f by which each glass may be secured in position.

In testimony whereof I afiix my signature in presence of two Witnesses.
