TOLEDO, OHIO.

e .it known that we, PARKER Cool: and WILLIAM E. WINE, both citizens of the United States, 'PABKER Cook residingV at 5 Washington, District of Columbia, and IL- .Lnur E. W'INE residing atToledo, State of Ohio, have invented certain new and useful Improvements in Tank- Siphons, of which the followin is a specification.

Our invention. re ates to new and useful improvements in siphon valves and especially to an arrangement for emptying tank cars.

As is well known the -general practice is to provide a tank car with a valve at the bottom thereof and to empty the tank by gravity, that is provide a valve at the bottom of the car which is operated from the I to}; thereof after the dome cover is open.

here are however many objectlons to the present form of valves employed at the bot- .tom of the tank car, for the reason that in a number of instances the valve has become jammed 01]? its seat, which resulted in the loss of the entire amount of gasolene in.

the tank car and onseveral occasions resultinfg in greatproperty loss and also loss of One of the objects of our invention therefore is to provide a valve mechanism whereby the tank is emptied by a siphon arrange ment, and wherein it will be impossible for the car in .transitto berelieved of its load of oil, or gasolene, or other fluid until a vacuum is first formed andwhich vacuum has to bestarted by a manual operation.

'Another object" of our invention is to provide a valve arrangement whereby the flow of gasolene or oil from the tank cannot be started until the dome cover is opened, thus avoiding anyaccidental flow or discharge of the contents. of the tank until desired; and also to provide an arran ement whereby if for any reason it is desired to stop the flow'or discharge of the tank, it is simply necemary ,to destroy the vacuum 1n the improved valve arrangement to be hereinafter fully described.

Still another object of our invention is to provide a. siphon valve arrangement for tank cars whereby there is no vacuum in the valve arran ment when-the dome cover is closed there y preventing any accidental discharge of the contentsofthe tank.

Specification 9 Letter! Intent Patented June 12 1917.

Application filed July 7, 1816. Serial No. 107,951.

Still another object of our invention is to provlde a tank car with the improved discharge arran started, and t at may be easily stopped by the breaking of avacflum, and wherein it Wlll be impossible for any loss of the con.- tents of the tank car unless the carshould happen-to be damaged by a wreck, etc.

Still other ob'ects of our invention are toprovide asip on arrangement that may be-quickly and: readily installed in the tank car s now in general use, or that 'may be quickly and easily provided in any forms of' new tank cars and at the same time complyv with all the requirements set out by the Master Car Builders Association.

With these and other objects in view our invention consists in certain new and useful improvementsand combination of parts as will be hereinafter more fully describedand pointed out inlth'e claims.

In the drawings Figure 1 1s a vertical ment that may be easily' section of the improved tank siphon arrangement.

Fig. 2 is a similar view but with the parts in a different position. r Fig. 3 is a transverse sectional view taken on line 33 of Fig. 1. y

Fig. 4 is a top plan view of the base member of the improved tank siphon.

Fig. 5 is a sectional view taken on line 55 of Fig. 2.

Fig. 6 is a detail view of the upper operating member of the bottom valve, and

Fig. 7 is an enlarged detail sectional view of the valve located at the upper part of the siphon and showing in dotted lines the valve in its closed posltion.

Referring now to the drawings -A dome 1 of the ordinary form 'used on tank cars is shown-having an opening and a cover 2 at the 'top thereof. It is to be "nderstood' that the form of dome or tank car form no part of the invention and thehereinafter described arrangement may be successfully'used with any of the general. forms now inuse.

Secured preferably centrally to the bottom of the tank is a casting 3 which will be hereinafter termed the base member? and as will be seen is riveted as at 4 after-a portion hasbeen out out of-t'he bottom of the tank, the said cutout portion being of nearly I the same diameter of the base member.

This base member 3 is preferably a unitary casting having the flange 5 at the upper ortion thereof WlllCl'l flange is riveted as'beore mentioned to the bottom of the tank car. In the bottom of this base member 3 is the discharge opening 6, which is extended and the outer portion is shown as threaded externally as at 7 for the receptlon of acap or nipple, so that a further discharge pipe may be secured thereto. Shghtly above the threaded portion 6, the base member widens at one side so that a valve 8 may be pivoted as at 9, which valve is operated by the tappet or stem 10, the lower portion of'whlch extends through the opening 11 in the base member 3 and the lower portion of said stem 10 normally'forcing' the outer end 12 of the valve 8 downwardly and thereby forcing the closing portion 13 of the valve against the valve seat 14 formed centrally of the base member 3.

The'said base member 3 has as shown a centrally located vertically extendin tubular portion 15, which tubular portion exte'nds above the level of the sides of the base member 3. vThis member is preferably cast integral with the base member and is imperforate at its bottom or in other words if so arranged that it is not possible for any fluid that comes within the base member to get withinthe said tubular portion 15 excepting that it pass up through the top member and down into the tubular portion 15 which action will be hereinafter described;

This tubular portion 15, is preferably internally threaded as at 16, and secured therein isthe pipe 17, the lower end ofwhich is externally threaded as at 18, and the upper end of which is designed to extend above the fluid level of the tank.

Referring for the moment again to the base member 3, it is to be noticed that the 7 central tubular portion 15 is also provided on its outer surface with four guide members 19 which members tend to strengthen the central member 15 and also to guide a casing 20 in itsupward and downward movement. A

This casing 20 as will be noticed is preferably threaded at. its upper end as at 21 to fit withinwhat I term the cap member 22, which cap member is internally threaded at its lower portion as at 23, and said cap and casing inc'loses the pipe 17, but the said casing 20. is open at its lower end.

' It will. be remembered that the pipe 17 is threaded at its lower end to he member 15,'and that the casing 20 is threaded tothe cap member-22 at its upper end, so that any variance in sizes of the difierent tank cars maybe easil .met, all that it is necessary to change, if t e cars are of difierent height,

being thelengths of the pipe 17 and cas- 4 dteferring now to the cap member 22, it

or guide member 28, which is secured to the inner surface of the dome, as at 29, this guide member 28 securely holding the cap member 22 in an alined vertical position; also by providing the shoulders 27 as mentioned it is impossible to raise the said cap member 22 and the casing 20 connected thereto above the position as shown in Fig. 2.

By using this member 28, the inner guide members 25 in the cap portion 22, and the lower guide members, a very rigid construction is obtained which of course is de sirable in an article of this kind.

A further brace member 30 is shown the ends of which member are fastened to the member 28 and which member partly surrounds the cap member22 and is also provided with a flanged portion 31 through which passes the upper end of the aforementioned stem 10. This stem has provided near its upper end and directly beneath the flange member 31 a spring 32, which is held in place by the stop or washer 33. Atthe upper end of this stem is a handle 34 which .is irregularly shaped, and said stem is normally held by the spring 32 in its downward position to normally hold the lower valve in its closed position. A movement of the handle 34 at the top of the stem 10 however will draw' the stem 10 upwardly thus allowing the lower valve 8 to open.

Referring again to the top casing 22 it will be seen that in its upper end is the opening 35 in which opening there is secured a valve 36 which valve, is provided with a handle 37 and it is to be especially noticed that when this handle 37 is in itsup'ward position the valve is closed, and when the handle sis in its downward position, the valve'is open.

In other words itis impossible to close.

the cover 2- unless the handle 37 is pushed downwardly and the valve is then and must be, in its open position.

A description of the operation of our ini 20 up to the normal level simple to break the oil or handle 24 and 'pull upwardl' on the same.

thereby lifting the cap 22 an the casing 20 upwardly until the shoulder 27 comes in contact with the brace and guide member a 28. As the upper valve member 26 is closed, and as the lower valve member 8 is also normally closed, the upward movement of the ca 22 and the casing 20, will form a partia vacuum in the pipe- 17 and in the top. of the cap 22, which vacuum will pull \solene up in the space between the pipe I? and casing 20 into the top cap and it will then flow nto the pipe 17.

The operator will then grasp the handle 34 and open the lower va vs 8 and the oil will then flow out of thepipe 17, thus start ing the siphon and will in this manner discharge the entire contents of the car. When the operatorreleases the upper handle 24, the top cap and casing 20 will of course lower themselves but will in no way efl'ect the si hon arrangement. If for any reason it is esired to cut off the flow of asolene, it will be only necessar to open t e valve 36 at the top which wou d break the vacuum in the ca and in the inner pipe 17 and the flow would of course instantly stop. Also the valve 8 might be operated t close the flow at the bottom but it is just as the vacuum as above mentioned.

It is to be noticed that when the car is in transit and the dome cover locked down,

the valve 36 will be open and even' should the valve 8 become disarrariiged cr jammed orin any manner forced 0 its seat, there will be absolutely no loss of the contents of the car as to et into this inner pipe 17 it A is necessary t at the cap 22 be manually lifted and that the up er valve be closed which cannot happen 5 the dome cover be closed.

From the above it will therefore be seen that with our improved arrangement it is impossible for the loss of the contents of the car unless the entire bottom casing was ripped ofl of the car and even should the bottom valve become jammed or held open still no 10$ of gasolene can occur, at the same time the arrangement is such that the flow may be easily and quickly started, or as easily discontinued as before described.

Mere colorable changes may be made without departing from the spirit and scope of the invention.
