WATER-HEATIN G APPARATUS.
Application led May 23, 1928. Serial No. 279,868.
The invention relates to water heating apparatus and more particularly to that apparatus which is adapted to be connected to the water jacket of a steam boiler or similar heat producing device and is operative to heat the water in a storage tank.
One object of the present invention is to provide an apparatus of this character in which the various parts consist of standard pipes, fittings, couplings and plugs so that no bolts or similar connecting means are necessary and the assembly operation is facilitated.
Another object of the invention is to provide a water heating apparatus in which the parts are so arranged that access may be had thereto for cleaning and the maximum heating eiiiciency is obtained.
A further object of the invention is to provide a heating apparatus of the aforementioned type in which provision is made for readily removing the parts for repair or replacement purposes.
A still further object of the inventionis to provide a water heating apparatus which is of a new and improved construction and may be fabricated or constructed at a comparatively low cost.
Other objects and advantages will be manifest from a consideration of the following detailed description.
The invention consists in the several novel Jfeatures hereinafter set forth and more particularly defined by the claims at the conclusion hereof. l
In the drawing which accompanies and forms a part of this specification or disclosure and in which like numerals of reference denote corresponding parts throughout the several views:
Figure 1 is a vertical longitudinal section of a water heating apparatus embodying the invention;
Figure 2 is an end view; and
Figure 3 is a transverse section taken on the line 3--3 of Figure 1 and illustrating in detail the eccentric position of the discharge pipe for the water that is to be heated.
rlhe invention is exemplified in an apparatus which is adapted to be associated with a steam boiler or hot water circulating system and is operative to heat the water in a storage tank (not shown). Although the apparatus may be used in connection with any wat-er storage tank, it is particularly and preferably adapted to be used in conextend vertically, a goose neck or drop is provided which insures the proper and desired circulating action of the cold water through the heating apparatus. The upper end of said pipe 5 is connected to an L-fitting 7 by a screw connection 8. A horizontal discharge or distributor pipe 9 has one end thereof provided with a male screw thread 10 which operates to connect said pipe to the upper end of the L-fitting 7 An elongated circulating pipe 11 has one end thereof positioned around the inner or discharge end of the pipe 9. This circulating pipe is substantially larger in diameter than the distributor pipe 9 and is arranged so that the latter rests upon the bottom thereof as shown in Figures 1 and 3. By positioning the pipe 11 in this manner, the top is spaced from the upper portion of the discharge pipe 9 and forms with the latter a conduit or passageway 12 through which the cold water passes to an outlet pipe 13. The end of the pipe 9 that extends into or is enclosed by the circulating pipe 11 is cut angularly as at 14 so as to form a nozzle which operates to direct the water toward the bottom of the pipe 11 as shown by the arrows in Figure 1. In forming the discharge nozzle on the distributor pipe 9, the cut is preferably made at an angle of approximately 30 and so that the upper portion of said pipe 9 extends or overhangs, the bottom portion. A characteristic and an advantage of forming the nozzle in this manner is that no auxiliary or supplemental water directing meansV is necessary in the fabrication of the apparatus. The cold water from the inlet pipe 5 flows to the outer end of the pipe 11 along the bottom and then is deflected upwards and flows in the opposite or reverse direction along the top of said pipe to the conduit or passageway 12. The water flows through this conduit to the outlet pipe 13. During the aforementioned circulatory movement, the water is heated as poses.` The plug 17 is provided with apolygonal head 1'9 whereby a wrench or sinnlar turning tool, may be applied. The lower Vend of the outlet pipe 13 is connected to the central branch of a. T-itting 20. One of the .end branches of this fitting is secured to a .screw thready 21 on the inner end of the circulat'ing pipe 11. The other end branch of the fitting 2O is secured to a nipple 22 which forms a continuation of the circulating pipe 11. The end of this nipple is connected to the' female thread of a coupling 24k. The latter is provided with an eccentric boss 25 `through which the outer or connected end of the distributor pipe 9 extends. A bushing 26` is interposed between the screw thread 10 on` said? pipe 9 and a female thread which is formedy in the boss 25. This bushing forms a closure for the nipple 22 and operates in conjunction with the boss ofthe couplingf24 `to properly position the distributor pipe 9 at the bottom of the circulating pipe 11. The upper end of the pipe 13 is provided with a union or coupling 27 whereby said pipe isconnected to the top or side of the water supply tank. Packing of any suitable character is inserted between the bushing 26 and the upper end of the fitting 7 to-prevent any water leakage around the screw thread 10.
The. circulating pipe 11 is disposed within a pipe or casing 28 which is substantially larger indiameter than the circulating pipe and forms therewith a acket 29. A heating medium` such as hot water or steam is cir`- culatedthrough this jacket so as to heat the cold. water from the supply tank as it circulates through the pipes 9 and 11. The medium referred to is supplied to the jacket 29 by means of a. vertically extending pipe 30 which,.if desired and convenient,v isA connectedto. the water jacket of a steamy boiler or similar hot water supply system. The lower endv ofthel pipe 30 isconnected to the central branch of a 'li-fitting 31. One end branchof this fitting is connected by a screw thread connection 32. to the inlet end of the casin'g28 and the other end branch is closed by a bushing 33 which is mounted on and is securedtothe screw-v thread 21 on the inner end of the circulating pipe 11'. The bushing 33. opera-tes to. support and position the circulating pipe 111 with respect to the pipe 28. By arranging the inlet pipe 30v of the hot water supply' so that it isf connected to the inner end of the circulating pipel 11 and is positioned in close proximity to the outlet pipe 13, the water leaving the circulating pipe receives the maximum amount of heat and consequently is the hottest. Obviously, this is of advantage inasmuch as the hottest portion of the heating medium is associatedV with and gives the final heating action to the water circulating back into the supply tank. Packing material is inserted between the bushing 33 and the T- fitting 2O to prevent leakage around the inner end of the circulating pipe. The e2;- posed part of the bushing is provided with a head 33L for turning purposes.
The hot water circulated through the water jacket 28 is discharged and returned to the source of supply through an outlet pipe 34. The latter is connected to the central branch of a T-litting 35. @ne of the end branches of this fitting is connected by a screw thread connection 3G to the outer end of the pipe 28. The other end branch of the fitting is closed by a removable plug 37. A head 38 is formed on the outer face of this p lug for use in turning the plug` into place. Vhen the'plug 37 removed. access may be had tothe water acket 29. The coupling 16 is positioned within the "f-fillin 35 shown in Figure 1 and a leg 39 is connected thereto. This leg operates to support the distal end of the circulating pipe 11 in concentric relation with respect to the casing.
The operation of the apparatus will be as follows.. The coldA water at the bottom of the water supply tank will be forced by virtue of its pressure through the inlet pipe 5 and into the distributing pipe 9 where it is subjected to the action of the nozxle end and is caused to flow along the bottom of the circulating pipe 11. During this travel or flow, the cold water is heated by the hot water which circulates through the water jacket 29. As the cold water reaches the end of the pipe 11, it is deflected upwardly by the plug 17 and then returns along the 'mp of said pipe to the passageway 12 through which it flows to the outlet pipe. 13 and thence to the supply tank. lilhen it is lesiredito remove the discharge pipe 9 and the circulating pipe 11. for repair or replacement purposes, the unions 6 and 27 are uncoupled and the bushing 33 is removed from the fitting- 31. This frees said two pipes` and permits them to'be withdrawn longitudinally from the inlet end of the casing or pipe 8. In the event that it is desired to remove the discharge pipe only, the union G is uncenpled` and the bushing 26 is withdrawn. This frees the discharge pipe so that it may be withdrawn lengthwise through the eccentric coupling 24 and the nipple 22. lVhen it is desired. tov clean the pipes 9', 11 and 28. the plugs 17 and 37 are removed.
Thev water heating apparatus disclosed herein is extremely simple and consists only loo lill) Cil of standard pipes, littings, couplings and plugs. It may be readily assembled and utilizes no bolts or other securing means whatsoever.
The invention is not to be understood as limited or restricted to the specific details set forth since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
