SPECIFICATION forming part of Letters Patent No. 371,467, dated @Sieber l1, 1887.

Application tiled January E9, 1857.

To all whom it may concern:

Be it known that we, WrLLLiM Winrrnrn Mavsnnr and FRANK Jonas, citizesot the United States, residing at Earling, in the county of Shelby and State of Iowa, have invented a new and useful Improvement in Railroad-Tanks, of which the following is a speciication.

Our invention relates to an improvement in railroad-tanks for supplying locomotive-tenders with water; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.

In the drawings, Figure lis aside elevation of atank embodying our improvements. Fig. 2 is vertical sectional view of the same on line a: x of Fig. 3. Fig. 3 is a top plan view. Fig. 4 is a detail view.

A represents a vertical supporti11g-frame of the usual construction, and B represents the usual railwavtank, which is supported on the upper side of the frame A. VIn the bottom of the tank is made adischarge-opening in which is located a metallic valvescat, C, having a depending slceve or nozzle, D, which-extends through the opening in the bottom of the tank. The Valveseat forms a circular disk, and from the upper side of the said disk, at suitable regular distances apart, project vertical rods lll.

F represents a circular disk which is provided with a depending nozzle, G, from one side of which projects a discliargespout, H. The lower end of the nozzle G is closed and is provided with a circular opening, I.

K represents a series of bolts which extend through the disks U and F, and also through the bottom of the tank and the upper side or iioor of the supporting-frame therefor, and serve to clamp the disk F to the under side of the platform of the frame and the disk C on the bottom of the tank. y

L represents a depending bracket which is secured to the platform of the frame A, near the disk F, and to the said bracket is pivoted the upper end of a depending link, M. To the lower end of the said link is pivotcd the inner end of a lever-bar, N.

O represents a vertical rod which extends through the opening I in the lower end ofthe nozzle G and np through the nozzle or sleeve Serial No. 225.910. (No modeLl of the valve-seat C, the lower end of the said Arod passing through an opening` which is made in the lever-bar N. To the upper end of this rod is attached a valve, l), which comprises a circular disk that is provided with a series of openings to receive the vertical gniderods E, so that the said valve will be guided vertically bythe said rods. On the lower side of the valve is a washer, F', which is made of leather or others'uitable elastic material.

R represents a packing of rubber which is arranged on the rod O and bears against the lower end of the nozzle G, so as to prevent leakthrough the opening [around the rod. A metallicwasher, S, bears against the lowerside ofthe said packing.

T represents a pair of blocks which are clamped to the rod O, one of the said blocks being arranged above the lever-bar Naud the otherblock bcingarranged belo w thesaid leverbar. These blocks are connected together b v links U, and screws V extend through the cxtremitics ofthe said links and enter the blocks to connect the links thereto, and si rnilar screws,

\V,eXtend through the central portions ofthe links and enter opposite sides of the leverbar N.

A coiled extensile spring, X, is placed upon the rod 0, and bears between the washer S and the upper block, T, the function of the said spring being to compress the said washer against the. packing.

From the foregoing description it will be readily understood -that when the free end of the lever-bar N is raised the rod O will be also raised, so as to cause the valve to be elevatcd above the valve scat, and thus permit water to iiow from the bottom of the tank out through the spout 'll into the tender of the locomotive standing on the track alongside the tank.

Y represents a vertical standard which is attached to one side of the platform at its lower end, and has its upper end attached to one side of the tank, so as to firmly secure the latter on the raised platform. To one side of the standard Y, near the lower end thereof, is secured a laterally-projecting block, Z, which is provided with a vertical slot. In the said slot is fulcrunied the inner end of a lever, A, which is provided with a semicircular cam,B,

IOO

the lever A depends a chain, D', which is.

adapted to be grasped by a person standing on the tender of the locomotive, when the latter stops at the tank, and by means of the said chain D the lever A may be lowered, thereby causing the lever-bar N to be raised, so as to open the valve and permit water to be discharged from the tank into the tender. In order to prevent the lever A from being depressed too far, I provide a chain, E', the upper end of which is attached to the upperside ot' the block Z and the lower end ot' which is attached to the lever A. As soon as the chain D is released by the person standing on the locomotive-tender, the lever A will be raised by reason ot' the spring bearing downwardly upon the lever-bar N, which is connected to the lever A. x

From the foregoing description and by reference to the accompanying drawings it will be observed that the operative parts of the tank which are liable to get out of order are located below the platform of the supportingfrai'ne, and are within plain sight and are easily accessible, so that necessary repairs may be readily made in a very short time.

By extending the rod which operates the valve downwardly through the bottom of the tank it is entirely protected from contactwith the water in the tank and thereby prevented from bccorningvfrozen and inoperative in the tank. A Ve are aware of Patent No. 122,583, in which is shown a discharge-pipe having a vertical and a horizontal arm and vprovided with a vertical opening in itslower side. The valve resting on the upper end of the vertical portion of the discharge-pipe is provided with a central depending stem which passes down through the opening in thel discharge-pipe,and a lever hung upon the discharge-pipe is connected to thelower end of this depending stem. In this patent a packing-box is employed below the opening in the discharge-pipe,and the said packing-box is practically the only support given the valve-stem; y

We are also aware of Patent No. 220,580, in which is shownahorizontally-operating valve, the stem of which projects through the side of the tank. This construction and arrangement necessitate the use of additional devices' to prevent the freezing of the stem.

It will be observed that we employno packing-box around the opening in the dischargepipe, and freezing at that pointis not so likely to occur, leakage being prevented by the packing R and washer S, held against the under side of the discharge-pipe by the spring X. It will also be observed that the arrangement andA construction of the parts ot' our device are such as to hold the valve -steni in a true vertical position at all times, and thereby prevent the valve becoming loose on its seat. By reference to Fig. 2 ot' the drawings it will be seen that the lever N serves to guide the lower end of the valvestem, and that the said stem is also guided by the vertical opening I in the discharge-pipe. The rods E also serve to guide and support the valve, and thevalvc-stcm exten ds downward through the bottom cross-braces of the supportingframe, and the said braces thus serve as an additional support and guide for said stem. The valve is thus guided and supported in a true vertical position, and can be very easily operated without becoming loose and rattling on its seat.

.Having thus described our invention, we claim- As an improvement in railroad-tanks. the combination, with the tank,of the disk C, havingl the vertical rods E,secured to thetloor of the tank, the disk F,secured to the bottom of the same, and having the discharge-pipe G H, provided with the opening I,projecting therefrom, the lever N,having one end'pivoted to a link, M, depending from the bottom o f the tank and its other end connected with the operatin g mechanism,the valve fitted on the rods E, and having the depending stem or rod O, passing through the opening I, the lever N, and the bottom'cross-braces of thesupportingframe, whereby three fixed supports or guides are provided for the valve-stem to keep the valve true to its seat, the blocks T,connecting the 'said rod to the lever N, and the packing R and washer S, held to the opening I by the spring X, substantially. as specified.

In testimony that We claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses. r
