TEMPERATURE-REGULATING APPARATUS.

,more particularly designed for use in photographic developing work.

The object of the invention is to provide a simple and practical apparatus of this character which may be used to either lower or raise the temperature of chemicals in a developing tray and for analogous purposes.

With the above and other objects in View, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully. described and claimed, and illustrated in the accompanying drawings, in which Figure 1 isa perspective view of my improved apparatus showing it set up for heat mg "a tray supporting table, the lamp or heater being omitted; Fig. 2 is a vertical section through the apparatus showing the lamp in posltion; Fig. 3 is a horizontal sectlon through the tray supporting or work table shown in Fig. 1; Fig. 4 is a view similar to Fig. 1 showing the apparatus adapted for cooling or lowering the temperature of developing trays or other objects placed on the table; and Fig. 5 is a vertical sectional view through the parts shown in Fig. 4.

Referring more particularly to the drawings, the numeral 1 denotes a supporting:

frame or stand having an open top portion in which is removably supported a body 3 of the temperature regulating apparatus or device. In the lower portionflof the stand 2 is a support at for an oil lamp 5 or a similar eater.

The body 3 is preferably in the form of a cylindrical drum and arranged within it .is a smaller drum 6, the space between said drums forming a water chamber 7. The closed ends 8, 9 of the drums 3, 6 are spaced apart and their opposite open ends are united by an annular bridge plate or ring 8. Formed in the side wall of the outer drum or body 3 are two threaded openings in which are removably arranged the threaded ends of flow and return pipes 10, 11 adapted to Specification of Letters Batent. Application filed January 25, 1909.

Serial No. 474,130.

to be heated or cooled by the water in the space 7 circulating through said pipes.

When the device is to be used for heating purposes itis arranged in the stand 1, as shown in Figs. 1 and 2, and the lamp 5 is placed in the bottom portion of said stand so as to project up into the inner drum 6, which latter forms a heating chamber; but when the apparatus is to be used for coolin purposes the body is removed from the stand 3 and inverted, as shown in Figs. 4 and '5, the pipes 10, 11 being interchanged in the threaded openings of the body or drum 3.

inner drum 6 forms a receptacle for ice or be closed by a removable lid or cover 12, When used as shown in Figs. 1 and 2, the heatand products of combustion from the lamp 5 escape through a centrally arranged the drum 6 "a cock 15 is preferably screwed.

into a threaded opening in the pipe 13 and this threaded opening may be closed by ascrew plug 16 when the cook 15 is removed vice, as shown in ig. 2.

' To permit thewater space or chamber 7 end 8 of the outer drum is formed with a @filling opening 17 adapted to be closed by a removable screw plu 18. 4

For the purpose of permitting water to be l drawn from the chamber 7 when the-body or drum 3 is in either of its two positions in the supporting stand 1', pipes 19, 20 are screwed intothe ring or plate S and the end Sand they are formed in their sides with threaded openings adapted to receive either a draw off cock 21.01 a plug 22. If desired, the outer ends of the pipes 19, 20 may be closed by screw plugs or caps 23. When the body is used as a heatin device, as in Fig.

when it is inverted, as shown in Fig. 5, said cook 21 is changed to the pipe 20.

24 denotes a work table or stand beneath the removable top plate 25 of which is arranged a coil of pipe26. The project ng l ends '27, 28 of the coil contain controlling have their other ends connected to a deviceother cooling mixture and its open top maypipe-13 which extends through the closed and when the body is used as a heating dea to be filled with water or other liquid the- 2, the cock 21 is arrange in the pipe 19 and Y PatentedNov.9,19(l9.

When used as shown in Figs. 4 and5, the

, valves 29, 30 and are detachably connected invention as especially adapted for this use,"l

I is claimed is: H

1. In a temperature regulating apparatus,

space 7 and as the heated water rises it will to cool or lower the temperature of developing the cover 12 to the latter.

arranged in the open top of the stand and consisting of outer and innerspaced drums united at one end by an -annular ring and by unions 31, 32 to the pipes 10, 11.

.In using the apparatus, when it isdesired to heat or raise the temperature of chemicals in the photographic developing tray, the latter may be placed on the top 25 ofthe table or, when sald top is removed, directly upon the coil as and the lamp 5 is lighted, the parts of the apparatus being arranged, as shown in Figs. 1 "and 2. The heat of the lamp will heat the water in the chamber or pass through the pipe 10, then throughthe coil 26 and return through thepi'p-ll, to the body, which latter in such'ease serves as a boiler. In warm weather, whenit is desired ing chemicals or the like, cold water may. be made to circulate through the coil 26 by removing the lamp 5'fromthe stand 1, in-' verting or reversing the position of the body 3 in said stand, as shown in Figs. 4 and 5, and placing ice or other temperature lowering material in the inner drum 6 and apply- From the foregoing it will be seen that the invention provides an exceedingly simple and practical deviceof this character which may be used either for raising 0r loweringeach being provided with a closed end, said .closed ends beingspaced apart as well as the remainder of said drums in order to provide a liquid-containing chamber closed at both ends of said drums, said pipe being adapted to be opened ,when the body is in one position and closed when in the reversed posi 'tion, and flow and return pipes communieating with said chamber adjacent-the opposite ends of the body. v

2. In; a temperature regulatin g apparatus, the combination of a body having outer and inner drums-united at one end by an annular ring v and having closed ends, said closed ends beingspaced apartf'as Well as the remainder of said drums in order to provide a liquid containing chamber closed at both ends, a' pipe'ex'tending throughthe closed ends of said drums, said pipe being adapted to be opened when the body is in one position and closed when in the reversed position, lion? and return pipes in communication with said chamber at points adj acent the opposite ends of the body, pipes projecting from the opposite ends of thebo'dy and in comm'unication with the spaces or chamber between i the drums, the lastmentioned pipes having the temperature of developing chemicals and, While I have shown and described the I it will be understood that the invention may be used in other ways and foroth-er pur 'tic-ns formed with openings, a cock and a plug interchangeably arranged in the lastmentioned 'openin s,-the closed en ofithe outer drum being, ormed with a filling open ing, a removable. closure for the latter, and

- Having thus described the nvention what the combination of a stand having an open top and means in its bottom forsupportmg aheater, a body removably and reversibly ends, a pipe extending through the closed T their outer ends closed and their side per l means'for supporting said body with either Y enduppermost, the last mentioned means being adapted to support a heater.

In testimony whereof- I hereunto affix my signature in the presenceef two witnesses.
