VALVEDHOUTLET EQUIPMENT FOR TANK CARS.

Application led July 1, 1922.

T 0 all whom it may concern.'

Be it known that we, THOMAS J. EN- 'rwI-sLr., HENRY P. OMAnA, and Jos/EPH lV. DONNBLLY, citizens .of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana,`have invented new and useful Improvements in Valved-Outlet Equipments for Tank Cars, of which the following is a specification. i

The object of our present invention 1s the provision of a valved outlet equipment of advantageous construction designed to be quickly and easily installed in the tank bodies of tank cars and lused in conjunction with outletlegssuch Vas at present in use, the outlet leg beingy changed in construction to alford Ia seat for the valve.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a vertical section illustrating our improvement as properly embodied in a tank car body in association with an old outlet leg.

Figures 2 and 3 are horizontal sections taken in the planes indicated by the lines 2 2 and 3 8, respectively, of Figure 1, looking downwardly.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The tank car body 1 is shown as provided with an outlet 2, and pendent from the bottom of the body 1 is an outlet leg 3, connected to the bottom of the body 1 by rivets 4. The said outlet leg is of the ordinary well known construction with the exception that a valve seat 5 is ground or out in the inner portion of the upper end thereof with a View to cooperation with the valve 6 of our improved equipment.

Our novel equipment in addition to the valve 6 includes an interiorly threaded valve casing 7, flanged at 8 to be connected to the bottom of the body 1 and the flange of the outlet leg 3 through the medium of the rivets 4 or other connections employed in conjunction with the tank body 1 and the outlet leg 8. It will also be noticed that the casing 7 is open at its upper end Serial No. 572,271.

and .is provided in its side and lower portion with what we designed side openings 9. The valve 6 employed is preferably of the same construction as the valve disclosed in our contemporary application of even date herewith, the said valve comprising a lower portion 10 with a convex face 11 for cooperation with the leg seat 5, an upper portion 12, a cruciform intermediate portion formed by webs 13 which are threaded on their outer threads 14, and a socket 15, preferably of interior angular form to receive the correspondingly shaped lower end of a valve rod or stem 16 which is connected to the socket preferably through the medium of a pin 17. The opposed faces of the valve portions 10 and 12 are concave as designated by 18 to facil tate passage of .oil or other mobile substance past the valve and through the casing 7.

It will be readily apparent from the foret going that in virtue of our improvement the valve equipment may be expeditiously and easily associated with and employed in conjunction with an old outlet leg 3 and the body 1 that carries said leg, and it will also be apparent that the valve 6 is adaptedto be tightly closed against the seat 5 with a view to preeluding leakage, and that the valve is also adapted to be quickly opened and closed with but little effort by turning of the rod or stein 16 about its axis. Manifestly when the valve 6 is first opened 1nobile substance will pass from the body 1 through the upper end of the casing and also through the side openings in the casing to and `down the leg 3. It will further be noted that when the valve is opened to a considerable extent as shown in Figure 1, oil or other mobile substance will pass froin the interior of the body 1 down through the upper end of the casing 7 past the lower portion of the valve to the outlet 3, and will also pass freely through the side openings of the casing 7 directly to the leg 8 so that when desired all of the contents of the body 1 may be drained directly to and through the outlet leg 3.

In addition to the practical advantages hereinbefore ascribed' to the subject herein, it will be noted that the said subject is possessed of the practical advantages ascribed to the valve and the casing disclosed in our said contemporary application of even date herewith. l

Ve have entered into a detailed description of the construction and relative arrangement o-f the parts embraced in the present and preferred embodiment of our invention in order to impart a full, clear and exact understanding of the said embodiment.. We do not desire, however, to b'e understood as confining ourselves to the specific construction and relative arrangement of parts inasmuch as in the future pnactioe of the invention various changes and modifications may be made such as fall Within the scope of our invention as defined in our appended claims.

Having described our invention, what We claim and. desire to secure 'by Letters-Patent, is l l. A valve for tank cars comprising a valve body structure mounted in an opening in the bottom of the tank, having an annular valve seat formed therein, and also having a threaded sleeve arranged concentrically of the valve seat and of a larger diameter than said seat, a valve 4having a cruciform portion, t-he edges of the Webs of said cruciform portion being formed for threaded cooperation with the threaded sleeve of the body structure, and one end of said cruciform portion having a partial spherical projection extending therefrom 'and adapted to engage beyond the seat, and operating means for rotating the valve in the sleeve for seating or unseating it, Whereby the partial spherical projection Will have universal seating cooperation With the valve seat, and the cruciform portion extending Ibeyond the seating portion, -directing the seating' pressure substantially in the line of cruciform portion, the edges of the Webs of Which are formed for threaded cooperation with the threaded sleeves of the body structure, one end of said cruciform portion having a partial spherical projection extending therefrom adapted to engage the annular valve seat, the portion of the ualve adj acent the spherical' projection and between the cruciform web being formed With inclined stress reducing Walls for distribut ing the application stress of the projection on the valveseat, equally through-out the cruciforrn portion of the valve, said spherical portion being adapted for universal seating cooperation with saidi annular seat, and the threaded cooperation between the ends of the Webs of said criiciform portion, beyond the circumference. of the partial spherical projection serving toapply the seating pressure in a line with the circumference of the annular seat and the axis of the valve, and substantially at the seating portion of said projection, and operating means `connected With the other end of the crucifo-rm portion for effecting a rotation of the valve in the sleeve for effecting the seating or unseating thereof. v1

In testimony whereof, We afix our signatures.
