IMPROVEMENT IN WATER-GAUGES FOR STEAM-BOILERS.
Specification forming part of Letters Patent No. 123,751, dated February 13, 1872.
I, EZRA W. VANDUZEN, of Cincinnati, Hamilton county, Ohio, have invented certain Improvements in Water-Gauges for Steam-Boilers, of which the following is a speciiication:
This invention relates to that class of gauges which serve to indicate the water-level by means of a pointer or hand adapted to revolve in front of a suitable dial, the pointer being operated by a stem or rod, which, after passing into the boiler, is bent rectangularly, and provided with a float; and the improvements consist in imparting a spiral or-twisted form `to the inner section oi' the s'tem, in order that the rotation of said stem may keep the inclos` ing-tube free of sediment or other obstructions; second, in a peculiar form of support for the inner end ofthe lioa't-rod.
Figure lis a horizontal section through a n fast to the hub D upon the rear of the dial E.
The float-rod F and pointer-stem G are two distinct and separate pieces or sections, having independent longitudinal movement, but
vibrating always in unison by reason of the outer end of the stem having a non-circular socket, j', that incloses a corresponding arbor, g, on the pointer-stem, as seen in Fig. 3. I is an India-rubber plug7 that presses permanently and immovably against a seat, d, so as to eft'ectually prevent the passage of steam and waterthrough the channel which is provided in the hub for the reception of the pointer-stem G. The plug I has preferably the conoidal form represented, and, being always out of contact with the sides of the chamber Within which it is located, it is free to twist or bend at every vibration of the stem without being dislodged from its seat d. The end pressure of the plug I may be assisted by a spiral spring, H, in the socket f. A prolongation or arm, K, from the inner end of tube A, terminates with an eye, k, that incloses and supports the inner end of the iioatrod.
In order to enable the ioat-rod by its vibrations to dislodge or remove any sediment or incrustation from the interior of the tube A, I prefertomake said rod of a twisted or spiral shape, as represented.
The open arm K is preferable to the ordinary prolongation ofthe tube itself within the boiler, such prolongation being liable to become choked with incrustations and sediment, and, by obstructing the free rotation of the ioat-rod, imparting false indications, and thus causing a device designed for safety to become an element of danger.
