WATER-GAGE.

Specification of Letters Patent.

Patented Apr. 6,1920.

Application led October 22, 1915. ySerial No. 57,280.

To all whom t may concemf Be it known that I, EDWIN MAGNEIR, a

` citizen of the United States, residing atl embodiment lof my invention,

1010 S. 48th St., Philadelphia, in the county of Philadelphia and State of Penna., have invented certain new and useful Improvements in Water-Gages, of whichvthe following is a specification. e

My invention consists of a Ynovel water gage in which the glass is pressure packed by the steam pressure exerted against the sides and rear face of the glass, and in which. the glass is held within the gage frame by a lateral or side pressure exerted on a gasket, the glass being preferably entirely out of contact with the frame.

It further consists of a novelconstruction and arrangement of gage frame and wedge shaped gasket whereby when the parts are assembled the gasket is moved toward the sides of the glass to lock the glass in position.

My invention comprehends other novel features of construction and advantage which will nbe clearly set forth in the detailed description.V K p The drawings are illustrative of `a typical but the invention is not limited to theieXact arrangeyity of separate layers.

inwardly diverging walls, between which the packing or gasket 14 is located. This packing is preferably formed ofva plural- The sight` member 12 has a sight opening 15 and the converging front wall 16. The rear faceof the v slght member has the angular shaped recess 17, one wall of which may be, if devsired, in alinement with the wall 9.of`the casing. 18 is a gasket which maybe dispensed with if desired, but I preferably PENNSYLVANIA, ASSIGNOR T0 THE EDNA BRASS i employa gasket of asbestos or other suitl ment and .organization ofthe instrumentahties employed as herein shown.

Figure 1 is a front elevation glass, typical of my invention. transverse .section on line l Fig; 8 is a sectional elevation taken on yline XY-X of Fig. 1. y

f Smilar numerals indicate corresponding parts.

Referring to the drawings 1A designates the casing o f which has the upper nipple 2 and the lower nipple 3 in threaded engagement therewith. The nipples are extended a desired distance from the frame and are adapted to be received in the usual fittings. and 3 communicate with the chamber 4 of the casing. The chamber 4 has a rear wall 5, forming a back ground for the p reflex glass 6, and the end walls of the chamber 4 are preferabl curved as seen at7 and merge ofva gage Fig.'2 is a X-X of Fig. 1. f. Y n

vwedge shaped gasket 14 is moved into firm lateral faces of the glass,

the -gage frame Y The nipples 2 Y the wall 9 at substantially right angles to f it. 10 designates thefront Wall of the casing,`which is inclined so as -to form with .the inner wall 11 of the sight member 12,

y contact with the able interposed between ,thek front face of the glass and theadjacent face of the sight member.

Vthis result, I have shown `a plurality of yokes 19, the erally free ends of which are deflected latand inwardly to cooperate with the heat re'sistingmaterial, andwhich is In the broad scope of my invenvtion the parts may. beheld in assembled front face of the s,1ghtmember. V13) designates set screws in threaded engagement with the yokes. and having their forward ends adapted to abutagainst the casing. It will be seen that the rear wall and a portion of the lateral walls of the glass are surrounded bythe steam and water pressure, so-that the glass is steam packed, thereby reducing the liability ofthe 4particles of the glass to vfly outward in case'the glass should become broken.

When the set screws 13 are tightened the owing `to'the'inclined wallsk 10 and 11, so that the glass is locked in position by the movement of the gasket 14 toward its side walls, which is preferably a sliding movement. .Y f

In so far as I am aware, I am the first in the art to secure theV glass Lin position by exerting a pressure on a gasket to cause it to slide inwardly against the lateral sides. of the glass and to have the rear face and a portion of the lateral faces of the glass steam packed, and I wish my claimsto such features to be construed with corresponding scope. .A

lAs above stated, the gasket 18 may be olispensed with as the glass is retained in position only by the pressure of the packing or Since sov the pressure of the steam is exerted against the rear wall of the glass and also against a portion of the side or lateral wall, an equal pressure is imparted against the glass at such points which causes it to be what I term steam packed or pressure packed. The only purpose of the gasket 18 is to keep the glass out of contact with the metal of which the casing of the gage frame is made. The tendency of the steam against the gasket 14 is to cause the gasket to be packed tightly against the side or lateral walls of the glass.

.I yclaim as my invention 1. A water gage, comprising in combination, a casing, a sight member, said casing and sight member having their adjacent faces forming walls diverging inwardly, a wedge-shaped packing between saidl walls,

1, a glass between said casing and sight member, and means to clamp said sight member and casing together to cause said packing to engage only the lateral walls of said glass, whereby the rear face and a portion of the lateral wallsl of the sure packed by the steam.

2. A water gage, comprising a casing having a chamber, a sight member, said e casing and sight member having their adjacent faces forming walls diverging inwardly, a wedge shaped packing between said walls, a glass forming a wall of said chamber, and means to move said packing toward the vlateral walls of said glass,

Y whereby the rear face and a portion of the lateral walls of said glass are surrounded by the steam within the gage to pressure pack the glass. f

3. A water gage, comprising in combination, a casing, a sight member, said casin and sight member having their juxtaposed faces inclined, a packing between said in-y clined faces, a glass inclosed by said casing and sight member and out of contactwith said'casing and sight member, and clamping means for said casing and said sight'member to cause said packing to slide inwardly to form a fluid tight ,joint with the lateral walls of the glass.

4. A water gage, comprising a casing provided with means to secure it in position, a sight member for said casing, the casing and sight member having opposed walls diverging inwardly, a glass within said casing and out of contact with the walls of the sight member and the casing, a wedgeshaped packing between said diverging walls of the sight member and casing and engaging only the lateral walls of the glass, and means to clamp the parts in assembled position, to cause` the packing to move laterally toward the lateral walls of the glass.

5. A water gage, comprising a casing having a'chamber with an openingthrough one wall thereof, asight member, a glass glass are presinclined walls at its sides located between' said sight member and casing, the inner face of said packing contacting with said glass, and means to cause relative movement of said sight member and casing to cause said packing to move toward the glass.
