WATER-HEATER.

Application filed December 27, 1916.

To all "whom it may concern:

Be it known that we, SAMUEL J. MAC- lliULLAN and J OHN M. ULMER, both citizens of the United States, residing at l/Villiamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Water-Heaters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art .to which it appertains to make and use the same.

This invention relates to water heaters of the sectional magazine feed type and has for its object to provide a heater of this character which will be simple in construction, comparatively inexpensive to manufacture and more ellicient in action than those heretofore proposed.

With these and other objects in View the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views Figure 1 is a transverse sectional view of a water heater made in accordance with this invention;

Fig. 2 is a partially sectional, partially elevational View taken on the line 22 of Fig. 1;

Specification of Letters Patent.

Serial No. 139,144.

Fig. 9 is a side elevational view of the parts shown in Fig. 8.

1 indicates any suitable support for the water heater, but preferably of the channeled form shown, 2 the individual sectional heating members provided with the flue spaces 3, and the hollow legs 4, and the connections 5 with the return manifolds 6, connected with the return pipes 7, all as will be clear from the drawings. 8 represents the hot water pipe leading from the 1nanifold 9 to the individual radiators of the heating system, and said manifold 9 is connected with the individual heating elements 2 as by the plurality of connections 10. Each individual heating unit 2 is provided with the substantially straight inner surface 12 bordering the combustion chamber 13 and with the substantially straight surface 141 disposed at an angle to said surface 12 as indicated. Each of said heating units 2 is further provided with the substantially straight surface 15 which is substantially parallel to the outer surface 17 and which borders the magazine space 16. Located inside the magazine space 16 are the supporting means 18 on which rests the manifold 9. At or near the lower end of each surface 15 there is provided the projection or solid lug 19 for a purpose now to be described.

In water heaters of the type made the subject of this invention, it is desirable to provide an automatic feed for the coal and to this end the magazine space 16 is restricted at or near its bottom by means of the member 20 which is provided with the annular space 21 for the accommodation of water and with the overhanging lip 22 adapted to rest upon the lugs 19 with which the individual units 2 are provided. The extreme ends 23 of said restricting member 20 also rest upon or are supported by the end casings 25 and 26 of the heater, the said. casings 25 and 26 being provided with the orifices 27 and 28 respectively through which said ends 23 are adapted to project, as will be clear from Figs. 2, 3 and 4 of the drawings.

Said casings 25 and 26 are also provided with lugs 29 to accommodate the overhanging lips 22 of the member 20, as will be clear from Figs. 3 and a of the drawings.

Said member-.20 is provided with the hot water pipe connections 30 and 31 adapted to afford a circulation through the space 21 and to convey the said hot water to convenient points for use when desired.

The said choking member 20 is also provided with the passage or hole 32 through which coal or fuel 33 may pass by gravity down into the combustion chamber 13.

Located preferably above said restricting passage 32 is the oscillating rod or member 3i provided with the fin or lip35 adapted to agitate the coal 33 and thus cause its more even distribution in the combustion chamber, as will be presently described. Said oscillating rod 34. extends to the out.- side of: the heater as indicated in Figs. 2, 3 and l, so that the coal may at all times be conveniently agitated, to insure an even automatic 'fee d thereof.

It will thus be seen that the coal 33 rests betweenthe straight parallel sides 15 of the individual sections, and upon the restricting member 20, so that a portion thereof passes under the action of gravity through the restricting passage 32 and down into the combustion chamber 13. Located in the co nbustion chamber 13 are the inclined grates 40 supported at their lower ends as upon the lugs ll and at their upper ends upon the member -12 which may be hollow as shown and also provided with a water space 4i3if. The lndividual'grate members 44 are conveniently pivoted as on the rods 45,

desired.

and saidmembers 44 are providedwith the extendingshanks 46 each connected to the reciprocating man as by the individual pivots 4C8. It thus results thatv by.reciproeating the rod- $7 each of: the individual members 44 willbe moved from their full line position shown in Fig; 6 to their fullas seen in Fig. 6 the said meeting edges 49 and =50 have separated so that the ashes may readily fall down into the spaces 52 between the individual members 4st and be caught between the surfaces 53 and 5liof said members a l all as will be clear from Fig. 7 0f the drawings. When new the bar 47-is reversed or moved toward the left as seen in Fig. 6, the curved surfaces 54: of the indi vidual members 44 will revolve under the ignited-coal, resupport the same and permit the ashes to pass down between the surfaces 53 and 5430f the said members 44. The re ciprocatingrods 47 are conyeniently led to the outside of the heater and operated by any suitable means as for example the levers 56 see Figs. 2 and In' the form of; heater shown in Figs. 1. and 2, the individual sections 2 may be conveniently secured to the manifolds 6 and 9 by the screw threaded connections 5 and 10 respectiyely, in the form shown in Fig. 3, tie rods such as 60 may be also used to hold thesections 2and. other parts together while in the form shown in Fig. 4, the hollow nipples 61 provided: with the opposed tapered cone like surfaces 62-may be employedovherever desired to secure the parts together. Further in the constructionillustrated in Fig. 4; the, inclined: grates are composedof a plurality of stepped sections 401 alnd l-O2, the outer or lower edge or endof the grate 401 being stepped in the ledge 65, and the inner or upper edge ofthe grate r02 being stepped-in the ledge 66 c-arriedby the bar6 7- as shown. Otherwise the construction of the grates is ormay be the same as illustratedin Figs. 1 2.and 3.

The operation of this improved heater will: be clear from the foregoing but-may be briefly sulmn'arized as follows The. individual heating sectionsare con veni'ently. castin substantially. the form shown, and are secured-totheir corresponding manifolds 6: and 9. and 1 other associated parts by any. suitableand wellknown means as indicated: 'Ihechoke member20 being. 1n place and the. stirring rod34- having its fin extending downthroughthe orifice 32- of; said mjember. 20,- coal is introduced through any. suitable ,door such as 70, and is permitted. to. automatically feed down and uniformly distribute itself over the inclined grates such 215340. The fire beinglighted theprodu'cts of combustion .p ass up through In other words, it is an important feature.

ofthe inventionthatinclined :grat'es are, as sociated with a watercooled choke member such as 20. provided with an agitator such as 35, for such a construction insures a more constant automatic feed-ofthe fuel andrcquires less attention than would otherwise be possible. In addition to this by inclining the fin 35'to the. right'or left so as to par:

tially close the opening 32, the quantity -013- coal passing through said opening can be restricted atwill and therefore, a. rough regu lat1on of the fire be had at all times. In addition, if it should be desired that the automatic feed of coal be substantially uniform both when the magazine is full and when it is only partially full the fin 35 may be held in an inclined position in the opening 32 when the magazine is first filled, and later adjusted to a more nearly vertical position as the coal is used up, thus causing a somewhat even feeding pressure to urge the coalv through said opening 32. In order that the coal may be evenly distributed over the grates a0, the control lever 7 6, Fig. 3, may be moved first to one side and then to the other and finally secured to one of the catch members 77 in the desired position. In addition to this when it is desired to run only one grate, as in the summer time, the fin may be left so inclined as to practically cut off coal from the other grate.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention and therefore it is not desired to limit this invention to the above disclosure except as may be required by the claims.
