GAUGE-GLASS AND rnnn enass PROTECTION.
Application filed September 19, 1925. Serial No. 57,273.
This invention relates to protective devices for gauge glasses of the type used on steam boilers and the like, and its principal object is the provision of an article of this character which shall prevent fragments of glass from flying outward in a dangerous manner in the event of the said gauge glass being blown out by excessive internal pressure, orby reason of the contact of cold drafts, or the like.
A further object is to provide this protection without obscuring the said gauge glass.
A further object is a device which may be readily put in position, or removed for cleaning, or the like.
It is further desired to afford a degree of reflection behind the said gauge glass to facilitate the reading thereof.
These and other advantages Will be dis-' closed in the following specification, and illustrated in the accompanying drawings, in which:
Fig. 1 shows the device mounted over a gauge glass; a portion of a boiler and adjacent fittings being shown in faint outline.
Fig, 2 shows a perspective view of the device with the locking element partly withdrawn therefrom.
Fig. 3 shows a perspective view of the invention with a modified form of locking members.
The construction of the device is as follows; referring to Figure 2 of the drawings; a transparent, flexible sheet 10 is secured within a frame having an upper band 11, a lower band 12, and vertical binding members 13 and 14; the whole being riveted, or otherwise suitably secured together as shown.
The binding members 13 and 1 1 are pro 'vided with longitudinal holes '15 and 16 which are adapted to receive the locking member 17 which is constructed with the lugs 18 and 19 and the grip piece 20.
It Will be seen, that with the locking member 17 removed, the frame may be sprung apart sufficiently to permit of its being slipped into position around the gauge glass 21 as illustrated in Figure 1. In doing this, the open portion is kept in a position in front, or at one side of the said glass and the locking member 17 is inserted and forced into full engagement with the frame members; this done, the device is revolved'to' apoint where the locking member will be in the rear of the gauge glass, and the upper and lower rims surrounding the holding nuts of the gauge frame.
The inner, rear portion of the device is preferably enameled with a light color and adapted to act as a reflector forthe said I gauge glass.
For a fuller understanding of the parts shown in F igure 1, adjacent to the invention proper; it maybe said that 22 represents the wall of a boiler, 23 the water line, and 2 and 25 the boiler connections etc.
\Vith reference to the modified form of locking device shown in Figure 3; a rod 26 secured within the binding member 27, which is the equivalent of' that shown at '13 in Figure 2, has upper and lower offset mem bers 28 and 29 with eyes therein 30 and 31 what we claim as new and desire to secure by Letters Patent, is as follows:
1. In an article of the class described, a
transparent sheath split longitudinally at one side thereof, frame members secured along the upper and lower edges of said sheath, binding members having apertures lengthwise therein secured along the longitudinal edge of said sheath, and a locking member having rod-like portions capable of being inserted in the said lengthwise apertures to secure the saidbinding members to ether in operative position, substantially as shown and described.
2. In an article of the class described, used in conjunction'with a gauge glass, the combination of a sheath of split tubular construot-ion, the forward major portion of said sheath being transparent, and the rearward portions having an inner surface of light off-set grip piece, said rod members being coloring capable of reflecting and bringing insertable in said longitudinal holes.
into prominence said gauge glass, binding In testimony whereof We have affixed our 10 members secured to the edges of the split signatures.
portions of said sheath, said binding members being formed with longitudinal holes, JOHN LUDVVIN'. and a double rod locking member having an ANDREW HOWARD.
