WATER-GLASS GUARD.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed September 13, 1906. Serial No.334.4=50.

To all whom it may concern:

Be it known that I, WILLIAM G. I-IALLIDAY, a citizen of the United States, residing at Fort Madison, in the county of Lee and State of Iowa, have invented a new and useful Water-Glass Guard, of which the following is a specification. 4

This invention relates to guards for watergages, and. its object is to provide a simple and inexpensive device of this character which can be readily fastened around a watergage and which when so placed will remain securely in position.

A still further object is to provide novel means for fastening the guard around the gage, said means constituting a reflector whereby the height of the water within the gage may be easily determined.

With the above and other objects in view the invention consists of certain novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a front elevation showing the guard in position upon a water-gage. Fig. 2 is a rear elevation of the guard detached, and Fig. 3 is a section on line 3 3, Fig. 2.

Referring to the figures by characters of reference, 1 is the glass tube of the gage, the same being mounted at its ends in joints 2 of the usual form and which communicate through pipes 3 with a boiler. (Not shown.) These parts are all of the usual or any pre ferred construction and constitute no part of the present invention, which relates solely to a guard for surrounding the glass.

The guard consists of a strip of heavy metal fabric 4, the ends of which are reinforced by metal rings 5, embracing the under edges of the strip. Reinforcing-strips 6 are also folded over and secured to the longitudinal edges of the fabric 4 and have extending outward from them headed lugs 7. An elongated back plate 8 is arranged to extend over the longitudinal edges of the guard, and this strip has its inner face polished, so as to constitute a reflector, while it is reinforced transversely and longitudinally by folding the edges thereof, as shown at 9. L-shaped slots 10 are out into opposite edges of the strip 8 and are adapted to receive the lugs 7. A semicylindrical plate 11 extends downward from and is rigidly secured to one of the rings 5 and has a recess 12 cut thereinto to form projections 13, adapted to straddle the lower joint 2 of the gage.

In using this device the strip 8 is first removed by pushing it upward so as to enable the lug 7 to be withdrawn from the slots 10. After the strip 8 has been removed the guard is grasped in the left hand with the slotted or open portion toward the operator, and the lower portion of the slot is then slipped over the water-glass just above the lower joint 2. The guard is then slipped over the lower joint 2, and at the same time the top portion of the guard is swung forward toward the operator and will therefore inclose the full length of the glass. The guard is then raised as high as possible and turned so that the slotted por- 7 tion will be in position back of the glass and is then lowered to cause the projections 3 to straddle the joint 2. position upon the guard either before or after the guard has been arranged with the open portion thereof back of the lass.

In removing the guard the strip 8 is first slipped out of engagement with the lugs 7, after which the guard is raised and turned until the open portion thereof is in front of the glass. The guard is then lowered as far as it will go, and the top portion thereof is pushed backward off of the glass 1, after which the entire guard may be lifted off of the glass. The parts when assembled are held securely in place, the ends of the strip 4 surrounding the alining portions of the joints 2, and it therefore becomes impossible to detach the guard, even though the glass be broken, without first raising it. It is therefore apparent that the guard constitutes an efficient protection against injury by broken glass, &c., in the event of the breaking of the gage-glass. Moreover, by providing the particular means for fastening the guard in place there is no necessity of utilizing screws or other fastening means. Another advantage is the provision of the polished face upon the strip 8, so that the same will act as a reflector to accurately indicate the height of the water within the glass.

The preferred form of the invention has been set forth in the foregoing description; but I do not limit myself thereto, as I am aware that modifications may be made there- The strip 8 is placed in in Without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall Within the scope of the claims.

What is claimed is 1. A guard for Water-gages comprising a metal-fabric strip adapted to embrace a gage, i

extensions pro ecting from the adjoining edge portions of said strip, and a combined reflector and connecting-strip arranged'longitudinally upon the fabric strip and having angular slots adapted to detachably receive the extensions.

2. A guard for Water-gages comprising a metal-fabric strip adapted to embrace a gage, extensions projecting from the adjoining edge portions of said strip, a combined reflector and connecting-strip arranged longitudinally upon the fabric strip and having slots adapted to receive the extensions, and means extending from one end of the guard for engaging a joint of the gage.

3. A guard for Water-gages comprising a metal-fabric strip adapted to embrace a gage, extensions projecting from the adjoining edge portions of said strip, a combined reflector and connecting-strip arranged longitudinally upon the fabric strip and having slots adapted to receive the extensions, and

an extension projecting from one end of the guard and adapted to bear upon a joint of the gage, said extension having projections adapted to straddle said joint.

4. A guard for Water-gages comprising a strip of metal fabric adapted to embrace a gage, the edges of said fabric being reinforced, headed lugs extending from the adjoining edges of the fabric, a combined refiector and connecting-strip disposed longitudinally upon said fabric and overlapping the edges thereof, said strip having angular slots adapted to receive the lugs, and a semicylindrical extension rigidly connected to one end of the guard and recessed to receive a joint of the gage.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of tWo Witnesses.
