WATER-GLASSv SHIELD.

SPECIFICATION forming part of Letters Patent No. 666,154, dated January 15, 1901.

Application filed May 17, 1900. Serial No. 17,05 7. (No model.)

To @ZZ whom t 777,001/l concern:

Be itknown that I, EDWARD T. REED, a citizen of the United States, and a resident of Port Jervis, in the county of Orange and State of New York, have invented a new and Improved Vtater-Glass Shield, of which the following is a full, clear, and exact description.

This invention relates to improvements in shields for water or gage glasses, particularly high'pressure glasses in locomotiveengines; and the object is to provide a shield that may be readily adjusted and attached to any water glass or gage, so as to prevent the engineer or other person from coming in contact with the glass and also to protect a person from the danger of flying glass and steam or hot water should the glass burst, as sometimes happens, and, further, to protect the glass from cold blasts of air or water and from breakage by careless handling of tools employed by workmen in making repairs in a locomotive-cab.

I will describe a water-glass shield embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had tothe accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section substantially on the linea@ of Fig. 2 of ashield embodying myinvention. Fig. 2 is a section on the line y g/ of Fig. 1. Fig. 3 is a detail showing a means `for supporting a reiiector employed, and Fig. 4 shows one of the clamping devices ein ployed.

The shield comprises a metal plate 1, bent substantially to cylindrical form, but having a longitudinal.opening 2 at one side. This shield is designed to engage around a waterglass 3-that is, around the front and sides thereof-and it is shown as engaged with the gasket-nuts 4 of the water-glass. As a further means of securing the shield in place I employ spring clampingyokes 5 and 6, which are forced around the shield, as indicated in the drawings, and to hold the clamping devices secnrely in position a latch-bar 7 may be employed to engage with the opposite members of each clamping device.

The lower clamping device 5 has at one side a forward projection or arm 8, from which a pintle 9 extends upward,and the upper clampv ing device 6 has a forwardly-extended arm 10, provided with an upwardly-extended pintle 11, provided with a screw-thread, with which a fastening or clamping nut 12 is to be engaged.

Arranged between the water-glass and the boiler is a reflector consisting of a mirror 13, arranged in a suitable frame 14, and this frame 14 is mounted adjustablyon the arms 8 and 10. As here shown, the frame has eyes 15 and 16, engaging, respectively, with the pintles 9 andll. This mirror is designed to receive the reection of the water-glass, so that the level ot the water may be observed by the engineer at any desired point, as it is obvious that the reiiecting glass may be placed at any desired angle and so clamped by the nut 12. The lower pintle 9 may be slightly tapered, if desired, so as to provide for any wear that may take place between the pintles and eyes, insuring at all times a practically close connection.

In order to accommodate the shield to different lengths of water-glasses, I may provide it at one end with a telescopic section 17, which may be moved in or out relatively to the main portion of the shield. This telescopic section 17 will be held as adj usted by its engagement with the lgasketnut. For convenience in moving the section 17 I pro vide it with a finger-piece 19, which projects out through a slot in the portion 1 of the shield and has a ring 18 attached to it, so as to swing, as clearly indicated in Fig. 1.

Removably connected to the front side of the shield 1 is a lamp 2O of any suitable construction. vThe light from this lamp is reflected through an opening 21 in the front side of the shield l,and consequently this light will illuminate the tube, causing it to be clearly shown in the glass 13. The body of the lamp maybe provided at the opposite sides ot its front opening with anges 22 for engagingin slideways 28, formed on the shield 1. This lamp may only be required atnight. Therefore in the day-ti me it may be removed, and a suit-able plate or door will be engaged with the slideways 23.

I design to employ a reiecting-surface with- IOC) in the shield i. This reIiecting-surface consists of a sheet of white or similar paper 24, held in place against the inner side of the shield by means of spring-plates 25. Preferably this reflecting device 24 will be of asbestos, so as to prevent a radiation of heat from the shield to the glass.

It will be seen that a device embodying my invention is very simple in construction and maybe readily attached to and as readily detached from a Water-gage, and this will be found convenient, because if the device is the private property of the engineer he may desire to remove it when leaving' his engine.

lVhile l have shown the device in connection with the water-gage of a locomotiveboiler, it is to be understood that it may be used in connection with water-glasses of stationary or marine boilers, and it may also be employed as a protection against the bursting of glass lnbricators.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- l. A water-glass shield adapted to partially surround a water-glass and to engage with the gasketnuts thereof, clamping-yokes for engaging around the shield, and a mirror mounted to sw ing` on said yolfes, substantially as specified.

2. A water-glass shield, adapted to partially surround a water-glass and to engage with the gasket-nuts thereof, clamping-yokes for engaging` around the shield, each of said clamping-yokes having` a projected arm terminating in an upwardly-extended pintle, a clamping-nut on one of said pintles, and a mirror mounted to swing` on said pintles, substantially as specified.

3. A water-glass shield, comprisingasheet of metal bent to substantially cylindrical form and having an opening at one side, a lamp adapted for connection with the shield and for throwing light through said opening, an asbestos lininbr or reflector for the shield, spring-clips for holding said asbestosin place, and a reflecting-glass adapted to be placed between the shield anda boiler, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing` witnesses.

EDWARD T. REED.
