warns-seen GUARD.

To all whom it may concern:

Be it known that I, Baron W. MCCLY- MONT, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Water-Gage Guards, of which the following is a specification, reference being bad therein to the accompanying drawings.

his invention relates to water gage guards, and the primary object of my invention is to provide an extensible guard which may be increased or decreased in its longitudinal dimensions to serve as a guard or shield for water gages of various 7 lengths.

A further object of my invention is to provide a simple, durable and inexpensive extensible water gage guard that can be easily and quickly installed to prevent pieces of a shattered, burst or otherwise broken water gage from injuring engineers, firemen or others in the vicinity of the water gage. This is accomplished without materially obstructing the view of the water gage, and the guard otherwise conforms to the requirement of State laws relative to the protection of workmen about water gages.

My invention will be hereinafter more fully described and claimed, and reference will be had to the drawing, wherein- Figure 1 is a side elevation of the guard as applied to a water gage, showing both partly broken away;

Fig. 2 is a horizontal sectional view of the guard;

Fig. 3 is an enlarged detail sectional view of extensible arms forming part of the guard, and r Fig. 4 is a perspective view illustrating a modification of my invention.

As illustrating an installation of the guard there is shown a water gage 1 made of-transparent material, as glass, with the ends of the gage or glass tube held in stuffing boxes 2 connecting the ends of the gage to water cocks 3. These elements are of the ordinary and well known type used in connection with boilers, and it is a well known fact that the glass tubes of such gages often burst and injure workmen adjacent the same.

The guard which I have devised comprises clamping rings or hands 4 adapted Specification of Letters Patent.

Application filcd iuly 24. 1916. Serial No. 110,906.

for embracing the stufiing boxes 2, said bands having clamping screws 5 which permit of the bands being clamped upon the stuffing boxes if occasion so requires.

Riveted or otherwise connected to one of the bands are the offset ends 6 of longitudinally slotted arms 7, and riveted or otherwise connected to the other of said bands are the ofiset ends 8 of longitudinally slotted arms 9. The arms 7 and 9 are comparatively flat and are equally spaced on the peripheries of the bands 4:, thereby providing interstices between the arms to permit of the gage being readily observed.

The ends of the arms 9 are provided with rivets 10 extending through the slots of the arms 7 and the ends of the arms'7 are provided with rivets 11 extending through the slots of the arms 9, the rivets 10 and 11 con stituting means for holding the arms 7 in sliding engagement with the arms 9, thus permitting of the longitudinal dimension of the guard being increased or decreased for use in connection with gage glasses of various lengths.

The offset ends 6 and 8 of the arms 7 and 9 respectively, place said arms in proximity to the gage glass and in parallelism therewith and while said arms are not of such width as to materially obstruct the view of the gage glass, yet said arms prevent large pieces of the gage glass when broken, from flying outwardly and injurin workmen contiguous to the gage.

he ofiset ends 6 and 8 of the arms 7 and 9 also serve another purpose and this is clearly shown in Fig. 1, where it will be observed that the offset ends of the arms 9 rest upon the lower stuffing box 2 and thereby relieve the lower band 4 of stresses and strains due to the weight of the guard. In some instances, it may not be necessary to positively clamp the band 4 on the stuffing boxes, particularly if there is suflicient friction between the arms 7 and 9 to support the arms 7 relative to the arms 9, without clamping the upper band 4 on the upper stuffing box. However, when the guard is used in connection with the water gages of the boilers of locomotives or other rolling stock, then it is preferable to fix the upper and lower bands on the gage fittings.

In Fig. 4, there is illustrated a slight modification of my invention, wherein solid arms 12 and 13 have straps 14 retaining said arms in sliding engagement, thereby obviating the necessity of slotting the arms and using rivets in connection therewith.

It is thought that the utility of the gage guard will be apparent without further description, and while in the drawings there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claim.

What I claim is A water gage guard comprising bands, extensible arms havin offset ends c0nnect- 15 ed to said bands an either of the-offset ends of the arms adapted for supporting the guard.

In testimony whereof I afiix my signature in the presence of two witnesses,

BRYCE W. MGCLYMONT. Witnesses:

KARL H. BUTLER, ANNA M. Donn.
