STEAM-COIL SUPPORT FOR TANK-CARS.

Patented Oct. 5, 1920.

Application filed August 21, 1919. Serial No. 318,986.

To all whom it may concern Be it known that I, JOHN D. SEILER, re siding at Milton, in the county of Northumberland and State of Pennsylvania, and being a citizen of the United States, have invented certain. new and useful Imrovements in Steam-Coil Supports for ank-(lars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it a ppertains to make and to use the same, reference being had to the accom anymg drawings, which illustrate the pre erred 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 modifications thereof within the scope of the claims w1ll occur to persons skilled in the art.

In said drawings:

Figure l is a vertical section through a tank equipped with my coil support;

Fig. 2 is a view showing one end of my coil support and its connection to the supporting bracket; and

Fig. 3 is a detail view the pipe support.

It has been found in tank cars provided with heating coils resting in sup-ports carried by brackets attached to the tank plates by rivets that leaks develop around the rivets after the cars have been in service for a short time. This is caused by thestrain showing an end of put upon'the rivets by inaccuracies in pressing the tank sheets to form, in placing the rivet holes in the tank plates and pipe brackets and in the height of the block that supports the center point of the pipe support which result in keeping the pipe coil support from resting on the tank bottom. Un-

less the center point of the pipe support has a proper bearing upon the tank bottom, the entire weight of the coils is carried by the bracket rivets, and this weight, under the jarring of service, works the rivets and the tank plates sufliciently to cause leaks between the rivets and plates. Where the center point of the pipe support is riveted to the tank plate, the inaccuracies of workmanship, -indicated above. cause all the rivets to be so stressed initially that the additional strains occurring in service cause leaks to develop between the bracket rivets and the tank plates.

It is the object of my invention to provide pipe support a means for mounting the pipe supports in tank cars so that there Wlll be no undue strain upon the bracket rivets and the center o1nt support will always have a proper )earing upon the tank bottom despite slight inaccuracies in the work and without the necessity of using center point supports of different heights.

In the drawings, 1 designates the usual car tank carried upon a car frame (not shown) in the usual or any desired manner. 2 designates the pipe coil carried by a support 3, the coil being secured to the support by U-bolts 4: which engage the pipes of the coil 2, pass through openings in the sup ort 3 and are secured therein by nuts 5 w ich are threaded upon the ends of the U-bolts 4. A bracket 6, fastened by rivets 7 to the tank 1 is secured to one end of the support 3 by bolts 8 which pass through circular openings in the support 3 and bracket 6. The other end of the support 3 is secured to a bracket 9, which is fastened by rivets 11 to tank 1, by bolts 10 which pass through circular bolt openings in the bracket 9 and through a slot 12 in the end of the support 3. p A bearing post 13, shown as U-shaped in the drawing, secured to the center p olnt of the support 3 by a rivet 14 and engaging the bottom sheet of the tank serves to support the center point of the pipe support. Providing the slot in the support 3 makes it possible to secure the 3 firmly to the bracket 6, the

olt openings in bracket 6 being such that bodily movement of the pipe coil and its support is prevented so long as the bolts 8 engage both bracket 6 and support 3, and to have a slight movement of the slotted end of the support 3 sufficient to bring the center support 13 to a proper bearing upon the bottom tank sheet. This will take place when the pipe coil is first installed and when, under the strains of service, the shape of the tank is changed sufficiently, the slotted con nection between. the pipe support 3 and the.

1. In a tank car, a pipamil, a support for said pipe coil, a bracket secured to the car tank for engaging said support anda connectionbetween said support and said bracket adapted to yield under the Weight of said pipe coil.

2. In a tank car, a ipe coil, a support for said pipe coil, a brac et for supporting one end of said pipe coil su port and a slotted connection between. said bracket and said support ada )ted to pcrinit longitudinal movement 0 said pipe coil support and under stress.

3. In a tank car, a pipe coil, a support for said pipe coil having a slot at one end, brackets for supporting said support and a yielding connection between the slotted end of the support and the corresponding bracket.

4. In a tank car, a pipe coil, a'support for said pipe c oil,'bra'ckets secured to the car tank for engaging said support, a bearing 0st for the )ipe support and connections etw een said rackets and pipe support for insuring engagement between the bearing post and tank.

5. In a tank car, a ipe coil, a support for said pipe coil, brackets secured to the tank for engaging said support and a yielding connection between said support and one of the brackets per'mittim the length of the sup ort between the brackets to change un er stress.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.
