JOHN L. NEWTON, OF UTICA, NEW YORK, ASSIGNOR T HART 8c CROUSE COMPANY, OF UTICA. NEW YORK. A CORPORATION.
BOILER-GRATE.
T 0 all whom it may concern:
Be it. known that I. Jonx L. NEWTON, citizen of the United States, residing at Utica, in the county of Oneida and Ftate of New York, have invented certain new and useful Improvements in Boilert lrates', of which the following is a specification. reference being-had therein to the accompanyin drawing.
My invention relates to an improved boiler grate, and I declare that the following is a full, clear, concise and exact description thereof, sufficient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout.
lhe invention has to do particularly with a grate which is used in boilers having the down draft, and comprises several features pointed out in the specifications and claims.
In the drawings Figure l is a perspective view of a portion of a hot-water heatingboilcr, showing theinvention, and Fig. 2 is a cross sectional view looking down on the line 2-2 of Fig. 1.
Referring to the drawings in detail. 1 represents the front of the boiler, 2 the various tubes or waterways for the water and steam, which are broken away on the side as shown so as to give a view of the. in terior. These waterways are-in various sections which form the outer walls of the ap paratus. except at the front, a d provide a depending portion which serves as the rear wall of the tire'hox' and allows space for the smoke and gas to pass, from below the grate. into the rear part of the apparatus whence they are conducted up the chimney.
3 shows the base and 4- the grate-bars.
It will he understood that the construction of such a furnace or boiler being well known is not set forth with great particularity of detail, but it is distinct from a steam boiler or the like which is incased in masonry, for the boiler itself is its own casing.
For the purpose of making the invention more clear, it should be noted that, for the purpose of getting a down-draft in a boiler, particularlv one adapted to burn soft fuel, various constructions have been proposed which included a series of pipes arranged parallel to each other to form a grate. for the fuel. with the air-passages between the Specification of Letters Patent.

Patented June 11, 1912. Serial No. 572,471.
pipes. the pipes being connected to carry a circulating medium to prevent their being burned out or destroyed by the heat of the fire. The ditliculty of producing a serviceable apparatus of this kind has been. for one thing. in connecting up the grate pipes, socalled. in a permanent and tight manner to allow for expansion and contraction and to provide for their being removed in case of necessity. So far as I am aware no apparatus of. this character has been designed which has been free from these objections, which I believe I have overcome in the construction here shown.
and ll show two headers placed at the rear of the tire-box and supported as on brackets 12, Fig. I. At the opposite or front end of the firebox are two similar headers. and 16. supported bvthebrackeb 1'7. one end of which is supported on the casing or fixed portion of the front boiler and the other end of which supports the two front headers. 'lhese headers. 10 and I5. have a nun'iber of pipes. 20. screw-mounted or otherwise suitably secured at each end in the headers. and the headers 11 and l() have pipes 21 likewise connected at each end into the headers. It will be understood that the headers and the pipes, as well as other porti ns of the apparatus, are to be made of material best suited for the use. The. headers resting on the bracket 12 at one end and being supported on the hanger 17 at the other endallowancc is made for expansion and contraction and for variations of contraction of each header and of the pipes between each pair of headers. The pipes 20 and 21 are laid on a slant or. in other words, one header is slightly elevated above the level of the other so that the eir culaiio'n of the water through the pipes is provided for.
Each pair of headers is connected on the outside of the boiler casing or water-way with pipes providing the circulation, and as the connections are the same on each side reference is made to a single set.
25 shows a pipe providing the intake of the condensation or other supply of circulating medium.
is a pipe suitably connected to having an elbow '27 from which pipe 519 connects with the pipe 29 which in turn is connected by pipe 30 to the header there being space enough in tubes 2 to allow for the movement, due to contraction and expansion of the grate, of pipe 30.
33 is a pipe connected to the other header and extending through the casing in a simi lar manner and having connected therewith pipe 3 1 which extends upward and connects with one of the tines or chambers of the boiler, as at 35. The pipes 30 and 38 each extend from their respective header through the casing or water-way of the boiler to the outside.
In assembling the parts the sections of the grate are each inserted through the door at the front and placed upon the supports. The pipes 30 and 33 may be put in the headers before the headers are inserted, or afterward as desired, it being apparent that this connection may be easily made as the work is done from the outside. The pipe 26 and joint 27 are, of course, connected on the outside and as the pipe 30 extends outward through the casing connection is readily made between the pipe 30-and pipe 26 by means of pipe 28 in joints 27 and 29. Likewise connection is made of pipe 34 with the projecting end of pipe 33, and connection also made at 85 into the chamber. Likewise the pipes may be readily dismounted and the sections of the grate removed. The ipes forming the connections are so disposed as to allow for the expansion and ('(iIItIHCtlOIi of the grate pipes as will readily be seen. The fuel being placed on the grate pipes, the draft is downward between the pipes and toward the rear and upward. The fuel not consumed falls into the grate bars and maintains further fire there and the products of combustion are consumed in their passage outward between the two bodies of tire.
IIaving described my invention, what I claim as new and desire to secure by Letters Patent, is: v
1. In a hot-water heater formed with an internal fire space, a grate formed in two independent sections, each of a plurality of pipes with a header at each end and'a pipe 'cxtending from each header outwardly through the wall of the heater and connected with the circulating system outside the walls of the heater, substantially as described.
2. In a hot-water heater as shown and described having an internal fire-space with portions of the circulatory system above and below said space, a 'rate in said firespace, composed of two in ependent sections each section having a pipe projecting through the external wall of the heater and connected on the outside to a portion of said system below the plane of the grate and a pipe likewise projecting and connected above the plane of the grate, substantially as described.
The combination with a hot-water heating apparatus having its exterior walls constructed as parts of a circulatory system, of a grate formed of independent sections and being part of said system and within the apparatus, eaclrsection being connected to the apparatus on the outside thereof and each section being removable when detached from such connection, substantially as described.
4. The combination in a heating apparatus, of members forming parts of a circulat-ory system and a grate forming a part of such system, the grate having a header at each end, one of said headers being loosely hung in position whereby to allow for the expansion and contraction of the grate.
5. In an apparatus of the character described, the combination of a casing forming part of a circulatory system inclosing a firespace, grate-sections in the tire-box, each section having headers severally prt vided with a pipe extending through the casing and there having connected members on the outside of the casing from said pipe to the source of supply, the said gratesections being adapted to act-as members in a circulating system.
In testimony whereof I hereunto attix my signature in the presence of two witnesses.
JOHN L. NEIVTON.
