JOHN BURNHAM, or BATAVIA, ILLINOIS.

IMPROVEMENT IN' WTER-TANKS FOR RAILRQADS.

Spcciiication forming part of Letters Patent No. 93,052, dated July 27, 1869.

To all whom yit may concern:

A water-tank, and Fig. 2 a top external view with a portion of the cover broken oft' to 'show the dead-air chamber beneath.

'My invention reta-tes to tanks and apl'iaratus.

at railway stations designed for supplying water to locomotives; and it consists mainly inthe novel arran gen'ient and applica-tion of devices intended to serve as eicient means for supplying water to locomotives, and of preserving such water from freezing whileit remains in such tanks.

The letter H ofthe drawings represents a watercistern, usually placed in the" ground. In ease the tank is placed over living vater, such as a stream or pond, this cistern may bc dispensed.

with. Upon lthe cistern H (or, in case there be no eist-ern, over the living fountain)` I erect a trame, of which the letters l) represent the posts, and letters M cross-bars, to serve as supports for the tank, next mentioned. The letterA represents my water-tank, arranged upon its frame, at such an altitude above the railway track as to bring its bottom above the boiler of the locomotive, to enable the Water to pass by its own gravity from the tank to such boiler. It is usually of aeircular form, constructed of staves, marked a on the drawings, and surrounded with hoops, marked Z1. The letters C ofthe drawings represent chambers, both at the top and bottom of my tank, formed by the construction of double covers and bottoms for said tank, and intended to serve as receptacles' for imprisoned air. I may, an d sometimes do, construct similar chambers, ex tending around the sides of the tank; but for all ordinary use the chambers at top and bottom are sufficient for the purpose contemplated. In a. tolerably mild climate the chamber in the top alone will answer therequiredpurpose. In the lower chamber C I arrange supports, represented by letter s; and .in both. the upper covers I con. struct inanlholes,.and 'close them with removable trap-doors, as shoivn ati/v, Care must be `taken in all cases tokeep the chamber C air-tight, except when opened by the trap-door The letter E represents the pipe through which the Water is passed, by pumping, from the cistern to the tank; and letterF an es apc-pipe, that conducts the Water from the tank to the cistern, when it has reached the desired height `in said tank.v The letter Grepresents thev conduit through which'r the 'ateris passed from the tank -tothe locomotive. The letters 'n represent ladders, arranged.

respectively in the' tank and cistern.- The space between the bottom of the tank and the top of the cistern, innnedia'lt-ely around the pipes E and F, is inclosed in an air-tight chamber, and, it' necessary, it is lillcd with suitable. packing, to preventsaid pipes from becoming inoperative by the freezing otwater therein. I also, when desirable, pack the chambers@ with suchcom -modities as will aid in preventing,r the'water in the tank from becomingtrozo, as that is the solo end and object of said chambers.

I do not claim, broadly, the invention'of the chambers l, for I am aware that chambers of a similar form have been used in Arefrig };erators5 nor do I claim, broadly, the invention of the pipes E and F; but

What I do claim as my invention, and desire.v

to secure by Letters Patent, is-V A The Water-tank for railway stations, herein described, having chambers G, mah-holes, and trapdoors pipes E and F, and conduit G, whenconstructed and arranged substantially as and for the purposes speeilied.
