DISCHARGE OUTLET FOR TANK CARS.

Application led September 9, 1921. Serial No. 499,504. f

To all whom t may concern.'

lie it known that I. JOHN J. Moliuuuc, rcsiding at Bayonne, Hudson County, State ot New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements' in a Discharge Outlet for Tank Cars, of which the following is a full, clear, and exact description, such as Will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompany- `ing drawings, which illustrate the' preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modiiieations thereof' Within the scope ot the claims will occur to persons skilled inthe art.

In said drawings:

Fig. 1 is. a central vertical section of my improved discharge outlet for tank cars; and

Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1, the outlet being shown in raised position in dotted lines.

It is the object of my invention'to provide an improved discharge outlet for tank cars of such construction that all parts ot the device may be protected by the car sills when the device is not in use or the ear is in transit.

In the preferred embodiment of my device shown in the drawings, a tank of any desired construction having a tank sheet 1 is mounted upon a suitable car frame having the center sills 2 and 3. Secured to the tank sheet 1, as by rivets, not shown, is a discharge outlet comprising a casting 4, threaded internally at one end to receive a valve cage in which a valve sleeve 6 and discharge valve 7 are operated by means ot a valve rod 8 and hand wheel 9. At its other end, the casting 4 is provided with an annular iiange 10 having a groove 11 in which is seated a packing washer 12 of any suitable material, as asbestos.

Rotatably mounted on the casting 4 is a casting 13 having an end adapted to surround the end of `the casting 4 and engage with the packing washer 12, the casting 13 beiner held in 'position on the casting 4 by the bolt 14 which passes through openings in the castings 4 and 13 and is provided with aspring washer 15 and nut 16. The adjustment ot nut 16 on bolt 14 is such that the cast-.ing 13 may be rotated on the casting 4 and there will 'not be leakage past the washer 12. Openings 17 are provided in the sills 2 and `3 for the insertion ot' the bolt 14 and the bolt 14 is held against rotation by having its head seated in an angular recess in the casting 4. The other end of the cast-ing 13 is closed by an outlet cap 18 in the usuall manner.

When the outlet is in use, the casting 13 will be i-n the position shown in Fig. 1 and when the car is in transit the casting 13 will be inthe position shown in dotted lines in Fig. 2. that is, rotated on the casting 4 until all` parts are above the lower edges ot' the center sills 2 and 3. The casting 13 is held in this position by a bolt 19 which passes through openings 2O in the center/sills 2' and 3 and is held in position by nut 21.

What I claim is:

1. -In a tank car, sills, a discharge outlet having a swiveled portion and means engaging said sills adapted to hold said swiveled portion in raised position.

2. In a tank ear, sills, a discharge outlet having a swiveled portion adapted to project below said sills and means adapted to hold said swiveled portion in raisedposltion.

3. In a tank car, sills, a discharge outlet lhaving a swiveled portion adapted to project below said sills and means carried by said sills adapted to hold said swiveled portion in raised positionbetween said sills.

4. In a tank car, sills, a discharge outlet having a swiveled portion adapted to project below the sills and means adapted to hold said swiveled portion above the lower edges of said sills.

5. In a tank car, sills, 'a discharge outlet mounted between said sills and having a swiveled portion adapted to project below said sills and means carried by said sills adapted to hold said swiveled portion above the lower edges of said sills.

6. In a tank car, sills and a discharge outletmounted between said sills and hav ing a swiveled portion adapted to be moved in a vertical plane from a position inwhich it projects below the sills to a position in wich it lies above the lower edges of the s1 s.

7'. vIn a tank car, sills, a discharge outlet having a swiveled portion adapted to be moved in a vertica plane from a position in which it projects below the. sills to a position in which it lies above the lower edges of the sills and means carried by the sills to l1old the swiveled portion in raised position. Y

8. In a tank car, sills, a discharge outlet `asing mounted between saidsills and comprising a rigid portion Yand a portion swiveled to said rigid portion and a cap cara ried by sa-idr'swiveled,portion, said casing being adaptedto retain the leakageY 9. Inra tank car, sills, a discharge outlet casing mounted between said sills and comprising a rigid portion lying :above the bottom edges of the sills and a portion swiveled to said rigid portion and adapted in one position to project belowsaid siis and in another position. to lie above the bottom edges of the sills.

10. In a tank car, sills, and a discharge outlet casing mounted between said sills, said casino* comprising swiveled sections adapted to project below said sills in one position and to lie above the bottom edges of the sills in another position and to retain leakage in both positions of said casing.

ll. In a tank car, sills and a discharge outlet casing mounted between said sills and comprising a rigid section and a movable section swiveled to said rigid section and adapted in one position to project below said sills and in another position to lie above the bottom edges of said sills, said casing being adapted to retain leakage in both positions of said swiveled section.

12. In a tank car, sills, a tank carried by: said sills, a discharge outlet casing between said sills comprising a casing section iixed to said tank and a casing section pivoted on said fixed section so as to maintain the pissagesin the two sections connected and means maintaining a fluid-tight joint between said casing sections.
