This invention relates to a method and apparatus for heating and transporting substances, especially liquids, and particularly such methods and apparatus in connection with rail mounted cars and the like.
While the use of refrigerated railway cars for keeping foodstufis cold during transportation is well known, heretofore it has not been possible to accomplish an opposite result and to maintain substances heated to a predetermined temperatureduring transportation by rail.
This is sometimes of advantage because it may be necessary to prevent chemical changes in the material being transported, or to prevent it from solidifying within the car whereupon it would have to be heated to be removed therefrom. Often it would offer an economy for the material to be hot when it reaches its destination in order to permit it to be used immediately.
Accordingly, the primary object of the present invention is to provide a method and apparatus for heating and maintaining heated substances being conveyed in a tank car.
Another object is the provision of a relatively simple arrangement for applying heat to a substance being conveyed in a tank car.
It is another object to provide a heating arrangement for a tank car which will not interfere in any way with the normal use of the car.
A still further object is to provide a method and apparatus for heating a tank car employing steam.
A still further object is the provision of a steam heating system for a tank car which is economical to operate.
These and other objects and advantages will become more apparent upon reference to the following description taken in connection with the accompanying drawings in which:
Figure '1 is a view ofone end of a car constructed according to this invention and having a portion of the insulating covering thereof broken away;

Figure 9 is a section taken on the line 9--9' of v Figure '7 and shows the manner of securing the frame of this invention to the central I beam which forms a part of the car frame;
Figure 10 is a section indicated by the line llll0 on Figure 11 and shows the appearance of the connection of the frame of this invention to the central I beam of the car frame in plan; Figure 11 is a side view of a part of the frame of this invention; and
Figure 12 is an elevational view taken at one of the corners of the frame of this invention.
Referring to the drawings more in detail,
Figure 1 shows a tank car which is substantially standard as regards the car frame or chassis indicated at It, the truck assemblies as indicated at E2, and the tank [4 carried by the car.
The purpose of this invention is to provide a heating arrangement for the tank M for transporting substances therein which may be main-- tained at a predetermined temperature and to this end there is provided a heating coil arrangement at 16 which extends along the lower part of the car and which is supplied with steam for maintaining the said predetermined temperature in the tank :4. 1
The entire tank l4 and the coil I5 are preferably covered by a layer of heat insulation t8 which is retained in position by a sheet metal covering 20 which is suitably secured to a super- 'an inlet valve at 24 and a discharge valve at 26.
The steam entering through the valve 24 follows 3 a serpentine path in passing through the heatin coil and efficiently transfers its heat energy to the tank.
It will be understood that both of the valves 24 and 26 could be inlet valves if desired whereby the sections of the coil l6 lying on opposite sides of the vertical center line of the tank would be connected in parallel thereby promoting uniformity of temperature over the entire heated surface.
The coil It may be, as shown in Figures 5 and 6, mounted on an arcuate bracket 28 which is spaced from the surface of the tank as by the channel means 30. A plurality of U bolts 32 secure the reaches of the coil Hi to the bracket.
Inasmuch as the coil it will expand and contract during the heating and cooling thereof it is rigidly supported on the tank at only one point. This is by the hanger 28 while the hangers indicated at 34 in Figure 2 are constructed as-shown in Figure '7, this view indicating that the U bolt hangers 36 and brackets 34 are over-size relative to thecoil l6.
As mentioned before, the layer of insulation l8 surrounds the entire tank and at the bottom of the tank said insulation is spaced from the tank to provide a'space for receiving the heating coil [6. The insulation prevents any substantial loss of heat from the heating coil while the space between the tank and coil prevents the development of hot spots on the tank. The material may be maintained at a relatively high temperature without any danger of burning the same;
The frame work which supports the insulation and the sheet metal covering 2!] thereof will best be seen in Figures 8, 9 and 10. It will be noted that secured to the central I beam 50 of the car frame is a fiat plate 52. The connection between the beam and plate is preferably by welding as indicated at 54. Extending laterally outwardly from the plate 52 are spaced T sections 56. The T sections preferably have the web part 58 secured t the plate 52 as by the angle clips 60 and the bolts 62. At the outer ends of the T sections 56 there is the longitudinally extending angle 64 which is secured to the T sections as by the angle clips 66 and bolts 68.
Extending vertically from the angles 64 which extend along each side of the car are the I beams 10 which have their lower ends secured together with the web part 58 of the T sections 56 to the angle 64 by the clips 66. These I sections, of which there are a plurality along the length of the car as indicated in Figure 2, have at their upper ends a longitudinally extending angle 12 which corresponds with the angle 64 at the bottom of the said I beams. Similarly to the arrangement at the bottom of the I beams, the angle 12 is secured thereto by the angle clips 14 and bolts 16.
At the ends of the car, there are the vertically extending angles 18 which are connected with the top and bottom angles 64 and I2 by angle'clips and bolts as at 80. A second corner angle 82 is disposed inwardly of the corner angle 18 and is also connected with the top and bottom frame angles 64 and 12 by the angle clips and bolts 84. A transverse angle 86 across each end of the car is connected with the inner corner angle 82 by the angle clips and bolts 88.
For further stiffening the frame assembly, the upper angles 12 are preferably welded along the side of the tank as indicated at 98 in Figure 8.
In joining the T section 56 to the plate 52 and the angle 64, the base of the said T section is 4 preferably cut off and only the web portion thereof extends over the said plate and angle. This is for the purpose of providing a continuous flat surfac commencing at the plate and extending along the top surface of the base of the T sec-l tion and on to the top surface of the base of the angle. This fiat surface is utilized, as gwill be seen in Figures 1, and 6, for supporting the blocks of insulation I9.
Similarly arranged, with regard to the flanges are the. vertical channel members and the angles 84 and '72. This will be seen in Figure 10 and the purpose of this arrangement is to pro vlde'space for receiving the blocks of insulation 2 I, best seen in Figures 1, 5 and 6. I
With the insulation around the bottom of the car prepared in blocks and mounted in this man:
her the removal thereof fer inspection of the coil'is very simple and any necessary servicing of the coil can readily be carried out.
After thefr'ame has been placed on 'the'ca'r and the heating coils assembled therewith, the insulation, which is preferably in the form of pads or blocks, is placed over the top and bottom of the tank and thereafter the sheet metal covering 26 is placed in position and secured to the farmework described above. The result is a car which is neat in appearance but which at the" sametime is well insulated against the loss of heat therefrom. 5" It will be understood that-the heating coil l6' could include suitable automatic control means such as thermostatically controlled valves or flow regulators if desired according to practices well known in the art.
Thecoil I6 is also preferably provided withthe brackets for the heating coil directly to the surface of the tank and, accordingly, it is desired to comprehend such modifications within this invention as may fall Within the scope of the appended claims.
