HEATING-COIL.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Application led October 15, 1917. Serial No. 196,569.

To all whom t may concern:

Be it known that I, FRANK H. LANGSEN- KAMP, a citizen of the United States, residing at Indianapolis, in the county of Marion Indiana, have invented a new and useful Heating-Coil, of which the following is a specification.

In tomato-canningV plants it is necessary that the tomato pulp be cooked. This is usually done in containers in which coils of steam-carrying pipe are located, so that these coils of pipe are immersed in the tomato pulp. Heretofore, these coils of pipe have been provided with numerous fittings, which are also immersed in the pulp. This has made the assembling of the pipe coils exceedingly diiiicult, and in addition the pipe fittings have been a source of contamination for the pulp, and have produced discoloring of the pulp in their immediate vicinity. Y

It is the object of my present invention to provide a pipe coil unit, which may be assembled separately and put in place in the container as a unit; which has a single compound supply and exhaust header which also serves as a main Support for the coil, and which preferably passes through the bottom of the container; and which has no pipe fittings within the container So that the contamination of the tomato pulp from such fittings is eliminated. v

The accompanying drawing illustrates my Figure 1 is a perspective view of two nested pipe-coil units embodying my invention, these units being shown separately from the container; Fig. 2 is a vertical section through a container in which said two nested pipe coil-units are mounted, the header of the outer pipe coil unit being in section; and Fig. 3 is a transverse section through such header.

Each pipe coil unit consists of a header 10 and a plurality of pipes 11 bent into circular form with their ends brazed in sockets 12 on substantially opposite sides of the header 10. When in use, the header 10 is substantially vertical, and the pipe coils l1 substantially horizontal; but preferably the receiving end of each pipe coil 1s slightly higher than the discharge end thereof, as is clear fromFig. 2, so that the water which 1s condensed from the Steam will How with the steam into the header. This is accomplished by properly oiisetting the sockets 12; The header 10 is hollow, and 1s provided with a vertical partition 13, which extends from the closed upper end of the header downward nearly to the bottom thereof, the lower end of such partition preferably being curved and joined to one side of the header so as to provide a. receiving chamber 14 and a discharge chamber 15. The receiving ends of the pipes ll communicate' with the receivlng chamber 14 through the corresponding sockets 12, and the discharge ends of such pipes communicate with the discharge chamber 15. The header 10 is provided with a laterally threaded opening 16 near its lower end, communicating with the receiving chamber 14 near its bottom, so that when the header is mounted in place a steam supply pipe 17 may be threaded' into such opening 16. The lower end of the header 10 also has an axially threaded opening 18, communicating with the discharge chamber 15, and receiving a pipe 19 for carrying o" the water which has condensed from the A steam.

The header 10 with its pipes 11 is assembled as a unit on the bench, and after being assembled is put in place as a unit in a container 20, the lower end of the header 10 projecting downward through the bottom 21 of the container. This container bottom 21 is rmly clamped between a lange I 22 on the header 10 and a clamping nut 23 mounted on a screw-threaded portion of such header, suitable gaskets 24 being provided between such bottom and the iiange 22 and nut 23. The part of the header below the threaded Iportion receiving the nut 23 is somewhat smaller thanthe remainder so as to allow the free passage thereover of such nut, and the openings 16 and18 are provided in this smaller portion of the header. The

pipes

17 and 19 are screwed into the openings 16 and 18 after the unit consisting of the header 10 and pipes ll'has been clamped in place by the nut 23. By thus clamping the header 10 in place by the nut 23, the main support of the coil is provided, but additional supports 25 may be provided for the pipes 11 at convenient points. These supports 25 rest either on the next lower pipes 11 or on'the bottom 21. Only one

hole

17 and 19 being attached to the header out side of such container. ri`he brazed joints of the pipes 11 in the sockets 12 do not'produce the contamina-tion which is provided by pipe fittings having leaded joints.

ln operation, the steam from any suitable source enters the receiving chamber 1i by the pipe 17, and passes thence through the coils 11, Where it gives up its heat and in large part condenses. The Water thus condensed passes to the discharge chamber 15, whence it is carried off by the pipe 19, preferably back to the source ot steam supply. Any number of coil units may be nested to gethei, two such units being shown in the drawings.

l claim as my invention:

A pulp heater, comprising the combination of a container, and e pipe oeil unit mounted in said container, said pipe coil unit comprising e rigid header and a pluiality of pipes each bent into are form and attached to said header at both ends of the arc, said arcforined pipes being located at different longitudinal points along said header and projecting generally transversely of the header, said header being provided with a longitudinal partition dividing it inte tivo longitudinal chambers With Which the pipe ends respectively communicate at dii'ierent longitudinal points of the header `for the different pipes, said header projecting as unit through the bottoni of said container to provide both an inlet and an outlet for the steam and being clamped to said bottom so that it also forms a rigidsupport for said pipe coil unit.

ln Witness whereof, l have hereunto set my hand at indianapolis, Indiana, this ninth day of Cetober, D. one thousand nine'hundred and seventeen.
