IMPROVEMENT IN PUMPS FOR. LOCOMOTIVE-TENDERS, &C,.

Specification forming part of Letters Patent No. 45,360, dated December 6, 1864.

To all whom it may concern.-

Be it known that I, A. I/V. TODD, of the city of Chicago, county of Cook, State of Illinois, have inventeda new and Improved Mode of Raising or Forcing Water; and I do hereby declare that the following` is a full and exact description thereof', reference being had to the accompanying drawings, making part of this specification, in which- In Figure 2,A represents a well to he made large in proportion to the demand of water, and to be sunk deep enough for the water to rise above the valve J, so that the water will llow in suilicient quantity to till the cylinder K up to said letter J. It' the cylinder K is entirely submerged, so much the better. 'Ihus it will be seen that when the valve O is raised by the rope l on windlass I to the hoop N, as seen above the cylinder K, `and is sufficiently weighted with any material, and released, all the water beneath it is forced up and through pipe L, the valve J being closed until valve O passes it, at which moment it opens, and the water rushing on top the valve O will add weight at the precise moment when it is most wanting or needed. rIhe cylinder K is made stationary by means ot' the frames G G G by two simple wedges, M M. It is ex.- pected that the well will be 'curbed and the posts I) l) spiked to it.

As the cylinder K sits on the bottom ofthe well, a suitable foundation should be provided to keep it from sinking when the bottom of the well is soft.

The transverse bar H is to keep the rod 2,

which raises valve O, in its place, secured by as suitable strip, as seen at H.

The weight P, swung over the windlass I, is intended to bring the valve O to its proper place when hoisted to its upper position.

The valve O is madeA suiliciently large for the quick egress ot' the water above it, thus y making but little resistance in 'being hoisted. rI`he iron hoops, as seen at G G G G, Fig. 2

` one at bottom and one at top-are to secure the frames G G G to the cylinder K.

In case either or both of the valves O and J should need repairing, it may be done by removing the wedges M M and transverse bar II. The cylinder K, frames G G G, and pipe L may all be raised above water by means of a rope being attached to the frames G G G and over windlass I.

The valve J can be screwed ott' and easily repaired.

Cylinders may be made of any desirable size, from two to six feet diameter by six or eight feet high, and placed in wells, cisterns, or any place where the water will rise to valve J, and the water may be forced to any height by adding weight to hoop N, as the diameter of cylinder and height the water is required to be raised requires, and so soon as the valve O reaches the bottom all the water in pipe L runs back, thus all trouble and expense caused by freezing is avoided, as it is not expected for any water to be raised only as it is wanted for immediate use.

C, Fig. 1, represents a drum or pulley of sufficient size to draw up with ease whatever weight may be swung to the windlass I, to which it is attached.

rIhe ropes T T, which operate the drum C, are passed around the pulleys F F, Fig. 2, which are made stationary, one on each side ot' the well at any desirable distance from it, and at the proper distance from the railroadtrack, so that as the locomotive passes slowly by the hook S is attached to it and carried as far beyond F as the hook Sis beyond F, as seen at Fig. l, dotted line. At the saine time the hook S is drawn to 3, Fig. l, ready to be attached to the return of the locomotive or train that may come the other way.

The drum C is intended to be attached and detached to wiudlass I by the ship and unship arrangement, by which arrangement the windlass I and hoop N run back without revolving the drum G. Thus the rope arrangement is kept in tact, and in case two or more trains should be going the saine way the pulley C and ropes T T and hooks S S are easily put C in proper position by hand.

'lhe hooks S S, when drawn by the locomotive to the proper point, are detached like the weight ot' a pile-driver, at which moment the pulley C is caught by the lever E at fulcrum E, and held till the water is ready to be received, when it is unshipped` from the windlass I, which revolves back, letting down the hook N and valve O, thus forcing the water through pipe L, while the drum C remains quiet, &c. Care should always be taken not to entirely release the windlass I and hoop N until the valve O is known to be in contact with the water, as in case of low water the valve O might be drawn above it, and if let fall would produce a bursting shook in all probability. The shield r, on the valve O, next the valve (or opening)J is to preventthe Water from passing around While the valve O is passing the inletvalve J. The opening V is the exit o1 Water into pipeL,Whiehis shown to be passed by valve after all the water is diven up through said pipe L, thus allowing I am aware that there have been many plans for raising Water 5 but What I claim, and desire toseeure by Letters Patent, is-

The combination and arrangement of the welll A, cylinder K, frames G G Gr, Wedges M M, hoops G Gr G G, pipe L, valves O and J, hoop N, rope and Weight P, rod 2, transverse bar H, orifice V, Windlass and rope I, stanohions or posts D, pulley C, with ship and unship arrangement pulleys F F, ropes TT, ooks S S, lever E, and fulorum E, sills B,

substantially upon the principle and iu the manner herein set forth.
