GAGE-GLASS HOLDER.

rammen aan. ai, iota..

To all whom z' may concern:

Be it known that I, FRANK G. DUNBAR, a citizen .of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and useful Improvements in Gage-Glass Holders, of which the following is a specification.

This invention relates in general to gageglass holders and aims to produce a device of this character, particularly adapted for employment in connection with gage glasses whichare connected at one end with a gage cock and at their upper ends with the top of a boiler through a flexible connecting tube, which will afford a simple and effective device for holding the tubular gage glass, to prevent vertical separation of the connections at the ends of the gage glass, and.

which will provide for the protection of the gage glass without obstructing the view of the same and will prevent particles of broken glass from flying in the cab in case the gageglass should burst or become otherwise accidentally broken while in use.

For the purpose of facilit-atin the explanation of 'my invention l have i lustrated on the accompanyingv drawings one practical form thereof from a consideration of which, in connection with the following description, the invention in one of its preferred embodiments will be readily understood.

Referring to the drawingsw-Figure 1 is a front elevation of a gage glass holder embodying my invention; Fig. 2 is a longitudinal sectional view thereof; and Fig. 3 is a transverse sectional view taken on the line 3.-.3 of Fig. 1.

By reference to "the drawings it will be observed that a gage cock 5 of any well known or preferred construction is threaded into the end of'a boiler 6 in the usual way. Iii-certain types ot' gages a companion gage cock, similar to the cock 5 illustrated, is also threaded into the boiler end some'distance above the lower cork, but in the form of gage wit-h which my invention is particularly adapted to be used the upper end of the gage glass is connected with the top of the boiler through a flexible tube. 'This manner of connecting the gage with the top of the boiler is believed by many to possess certain advantages in that dry steam from. the top of the boiler is introduced into the gage-glass above the water level therein reardless of the height of the water in the oiler. 1When a flexible tube is employed' to connect the upper end of the gage-glass with the boiler, obviously some rigid form of support must be employed for holding the gageglass and preventing lateral movement of the upper end thereof which would result in breaking the glass. It is for the purpose of providing a rigid support for the gageglass, to prevent breakage of the same and also for the purpose of holding a'gageglass shield around the gage-glass, that my present invention was designed.

The gageglass 7, f usual construction and any desired length, has its lower end connected with the gage cock -5 in the usual manner. The holder, designated generally by reference character 8, is preferably made integral and for cheapness in manufacture may be cast in one prises a back provided with a longitudinally extending opening 9 through which light may pass so that the water level in the gage-glass may be readily observed. The back is provided at its side edges with forwardly extending flanges 1() and 11, respectively, adapted to receive therebetween the rear edges of a horseshoe-shaped shield 12. The ends of the holder are provided with forwardly extend-ing upper and lower flanges 13 and 14.-, respectively, between which the upper and lower ends of the shield 12 are adapted to be slid into position. The lower end of the holder is threaded' as indicated at 15 for engagement with the gage cock and the upper end is similarly threaded at 16 for engagement with a coupling 17 to which the flexible tube f8 connected at one end with the top of the boiler is attached by means of the packing nut 19. It Will be noted that the threaded sockets 15 and 16 form tubular couplings carried by the respective ends ofv the holder.

piece. This holder com-4 noholder provided for steadying the glass.

The shield 12, preferably made of wire glass,

is slipped into vposition between the upper.

and lower flanges 13 and 14: so that its rear edges are embraced by the side flanges 10 and 11. The flanges 13 andlll are pfvid'd with openings to receive a retaining and locking rod 2/0.r This rod is preferably made of spring material and is curved as shown in-Fig..2 so that afterit is inserted through the flanges 13 vand 14 it maybe given a quarter turn into the position'shown in Fig. 2 to bring the bent pont-ion into engagement with the shield 12 thereby forcing it tightly against the holder and locking it in place and preventing it froln rattling. In order to hold the rod 20 lin locked position the opening 21 in the flange 13 is preferably elongated, as shown in Fig. 8, to receive the lower portion of the loop 22 formed on the upper end of the rod 2() whereby said rod is prevented from turning. A small key E23 may be inserted through the lower end ofthe rod, if desired, to prevent the same from working out. l

From ,the foregoing it will be manifest that I have provided a simple and, substantiall holder adapted to steady the upper end of the gage-glass and also to' afford a Support for a gage-glass shield. The flanges on the holder, together. with the locking fed, retain the shield in position around lthe glass thereby' protecting the engineer from flying` fragments. in case the gage-glass should become broken and-,the open back of the holder together with the glass shield permit the water level in the gage-glass to be readily observed. Furthermose, it will be obvious that while protecting the gageglass and also affording Aprotection to the engineerl have not obscured the gage-glass .or placed any obstacles around the glass which would interfere with its-observation.

The invention, however, is, inV its broad as- I peet, not limited to the details vof', construc tion illustrated and described, but obvipusly open to expose the tubular gage glass to ,l

view, a tubulancoupling provided upon each of .theftopand bottom flanges in alinement with the opening therein, and a gage glass protector carried by the holder and extendl' ing from one flange to the other flange, substantially as described.

3. A gage glass holder vcomprising a backv having top and bottom flanges -projecting at the front of theback and'rigidly fixed thereto, said flanges havingalined openings for the reception of a tubular gage glass, the front and sides'of the holder being open to expose the tubular gage glass to view, a tubular coupling provided upon each of the top andy bottom flanges in alinement with the opening therein, and a gage glass protector carried by the holder and extending from vone flange to the other flange, each of the flanges having port-ions` extending in front` of the protector and provided with openings, and a locking rod extending through said openings and incontactl with the protector to hold the same against lateral displacement.

A gage-glass protector comprising a holder adapted to accommodate a gage-glass anda gage glass shield said holder including a back provided on its longitudinal edges with flanges to accommodate therebetween the longitudinal edges of the gage-glass shield and provided at it-s top andvbottom with flanges rigidly fixedto the back and adaptedto accommodate therebetween the ends of said gage-glass shield.

5. In a gage-glass protector, the combinal tion of a holder adapted'for engagement at one end with a gagecock and at its other end with a flexible tube, said holder being provided with oppositely disposed flanges, a gage-glass shield positioned between said flanges, and yielding means for locking said .shield in position.

6. In a gage-glass protector, the combination of a holderadapted for connection at its ends with a gage cock and a flexible tube,

said holder being provided with side flanges and top and bottom flanges, a gage-glass shield positioned between said flanges, andv a resilient bent rod engaging with said upper and lower flanges `and adapted-to yieldingly lock said shield in position.

7. In a gage glass holder and protector,
