\ WTEB-HEATING ATPABATUS.

Specification of Letters Patent.

Application filed October 28, 1911.

Patented Aug. 13, 1912.

Serial No. 657,825.

To all whom it may concern:

Be it known that we, LOUIS J. RIssLmo and Jme C.R1ssnmo,citizens of the United States, and residents of thecity of Chicago,

county of Cook, and State of Illinois, have invented certain new and useful Improvements in Water-Heating 7 Apparatus, of which the followin is a specification.

Our invention re ates to im rovements in m water-heatin apparatus and as for its object the pro uction of a heating apparatus especially designed for domestic use, as in the kitchen.

A further objectis the production of a heating ap aratus as mentioned, which will be of dam le and economical construction, one in which water may be heated economically and with great expedition and one which will be of hi 1. efficiency in operation.

Other objects wi appear hereinafter.

With these objects in view, our invention consists in the combination and arran ement of arts hereinafter described and c aimed.

ur invention will be more readily understood by reference to the accompanying drawing forming a part of this specification and in which,

Figure 1 is a central vertical section of a water-heating apparatus embodying our inso vention, and Figs. 2 and 3 are transverse sections taken on line w:v and y-y respectively of Fi 1.

The pre erred form of construction as illustrated in the drawing comprises a base or supporting member, which consists of legs 1, adapted to contact with the ground or floor, the up er ends of said legs being rigidly connected by a ring 2, said rlng rojecting slightly above the upper ends 0 the to legs 1 for a purpose which will be hereina ter set forth. Mounted upon said base member and more precisely upon the inwardly projectin u per ends of the legs 1 is a cylinder 3, w ie is closed at both ends to adapt the same for the reception of water. Traversing the interior of the cylinder 3 is a plurality of longitudinally extending fire tu es 4, the latter openin and being rigidly secured in the respective eads of said cylinder as clearly shown in Fig. 1.

Surroundin the cylinder 3 is a cylindrical or tubu ar casing 5 which is open at bothv ends, thelower end of said casing fitting within the upper end of a ring 2 and 65 being-supportedupon the inwardly projecting ends of the legs 1. The casing 5 is of a diameter slightly reater than the cylinder 3 so that an annu or space will be formed around the lateral wall of the cylinder 8 for the assage of heated gases or products of com ustion as will be hereinafter set forth. Arranged above the casing 5 is a second cylinder 6, the lower end thereof being fitted snugly within the upper end of said casing and supported upon angular brackets 7 secured upon the inner side of said casing. The casing 5 is of a height greater than the cylinder 3, so that a chamber 8 will be formed intermediate the adjacent heads of the cylinders 3 and 6.

The interiors of the c linders 3 and 6 communicate with each ot er through pipes 9 and 10, the upper end of pipe 9 being secured in the lower head of cylinder 6, the lower end of said pipe 9 passing through the upper head of the cylinder 3, and terminating within the latter adjacent the lower end thereof. The pipe 10 1s secured at its lower extremity in the upper head of the cylinder 3, the upper end of said pipe, passing through the lower head of cylinder 6 and terminating within the latter adjacent the upper end thereof. Unions 11 are preferably interposed in the pipes 9 and 10 in order to aiford adjustment 1n assembling of parts of the ap aratus.

Arranged with the cylinder 6 is a. plurality of longitudinally extending fire tubes 12, the lower ends of said tubes being secured in the lower head of said cylinder so as to open into the space 8 intervening the adjacent ends of the cylinders 3 and 6. The upper extremities of the tubes 12 communicate with ahollow disk 13 arranged within the upper end of the cylinder 6, the upper side of said disk communicating with outside atmosphere through a tube 14 which opens, as shown in the upper head of said cylinder.

Water is su plied to the cylinder 6 through the in et pi e 15 which passes through the upper hea of said cylinder and through the interior of the'latter terminating therein adjacent the lower extremity of said cylinder. The outlet pipe 16 is secured in the upper head of the cylinder 6 so as to communicate with the upper end of the latter.

In the operation of the apparatus the water will be supplied as above mentioned through the pipe 15. A portion of the water thus supplied will drain from said 15 same come in contact.

30 the member 13 utilizin 45 comin inoperative.

I .which may be removedii-f desired for thel so the element 17, when this is done being dis-i 60 *tions an I sage ,of the. appended claims.

5 combustion arising from the lleflllll element 171will ascend ithe fire tubes 4, and the annular passage surrounding the cylinder 3 and enter the s ace 8 intervening the cylinders 3 and 6. rom the space 8 the gases will ascend'tlie'fire tubes 12, entering the hollow member '13 whence the same will be discharged through the tube 14, the gases and roducts of combustion thus directed effectingthe heating of the walls with which the The lower head of the cylinder 3 will erhaps be more intensely heated being in c ose proximity with the lame at the heating element. Also it will be observed that the entire outer surface of the cylinder 3 will be exposed to the action of the heated gases and products of coinbustion, so that the water contained therein will be heated with great expedition. The gases entering the space 8 will effect the heating of the portions of the pipes 9 and 10 traversing said s ace and also the effectual heating of the ower head of the cylinder 6 upon which said gases and prod-' ucts will impinge, the pipes 12 and 14 and practically all of the remaining heat of t e gases before dis-. charge thereof; this practically complete utilization of the heat generated at the heating element conducing to economy.

By reason of the disposition of the heat in the cylinders 3 and 6 and also by reason ofthe peculiar arrangement of the pipes 15, 9. and 10, and 16 the circulation from the cylinder 6 downwardly through the pipe 9 into the cylinder -3 and upwardly through'thepipe 10 will'be e'ifected, the water being finallydischargcd through the pipe 16. Thei device is durable and economical in construction and is not susceptible to readily be- 5 I Screw plu s '1 8 are; provi ed in the cylinder 3 an casing 5} connection of the a paratus with a stove,; furnace orother simi ar element for heating pensed with. lVhilewe have llustrated and described? the preferred form of construction for car-l rying our nvention into effect, this is capabit! ;of variation and modification without :de arting. from the spirit of the invention. l e therefore do not wish 'to be limited to i .the exact details of construction set forth,
