STOVE.

To all whom it may concern.

Be it known that I, SAMUEL V. Rnnvns, a citizen of the United States, residing at Haddonfield, county of Camden, State of New Jersey, have invented a new and useful Stove, of which the following is a specification.

My present invention relates to a novel construction of a stove wherein provision is made for reducing to a minimum the clogging of the rear part of the grate and provide a better circulation of the air beneath the grate.

My invention in its board and generic scope consists of a novel stove wherein provision is made for the free circulation of air along the rear fire line, a novel construction of grate and grate support being provided, and also a novel arrangement of dust pipe.

It further consists of a novel construction of a base or ash pit and a novel construction of the cylinder forming the lower fire chamber, wherein the cylinder is cylindrical but at the lower portion below the fire line, is made oblong or outwardly deflected at its rear portion in order to cooperate with the oblong or pouched section of the case upon which it rests, the lower portion of the cylinder being adapted to be used on either a circular base or on an oblong pouched base, such as is herein shown.

It further consists of a novel construction of a base, the rear portion of which is oblong and preferably removable, such oblong portion forming a chamber in rear of the grate to collect the ashes, such sections also being provided with means adapted to interlock with the grate rest while the forward portion of the base portion is provided with means cooperating with the grate to guide the same in its movement.

It further consists of a novel construction of a reversible rest or support whereby, in

case the same becomes warped or distorted,-

it may be readily reversed, such rest being adapted to carry the movable grate and being provided with means for interlocking with the base of the stove at points exterior of the fire zone, thereby greatly increasing the durability and life of the rest or support and incidentally the grate and tire cylinder.

It further consists of a novel construction of a grate, the top and bottom of which are constructed in a similar manner whereby, in case one side of the grate becomes dis- Specification of Letters Patent.

torted due to the heat then such grate may be readily reversed.

It further consists of a novel construction of a grate provided with a journal removably connected therewith and adaptedto be rotatably mounted on the reversible rest or support for the grate.

It further consists of a novel manner of interlocking a reversible draw or shaking bar with the grate and also a novel construction of draw or shaking bar wherein provision is made for preventing the ashes or cinders being carried along the top of the draw or shaking bar, and escaping into the room or place in which the stove is installed.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings those embodiments thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Fig. 9 represents a sectional view of the grate in detached position. Fig. 1.0 represents a sectional plan view of another embodiment of my invention, wherein the fire pot or cylinder is provided with an opening which may be closed in practice in any desired manner. Fig. 11 represents a sectional elevation of a complete stove embodying my invent-ion.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: 1 designates the base of the stove which may be supported in any desired manner, and which forms the ash pit 2 in the usual manner. The upper flange 3 of the base port-ion 1 is cylindrical, except at its rear portion, at which place it is outwardly deflected to provide an oblong o pouched portion 4, as will be clearly understood by reference to Fig. 1, and such oblong portion is provided on its inner face with a reinforcing rib 5, the upper end of which forms a support for the rest bar 6, and is provided with an upwardly extending lug 7.

Thefront portion of the base 1 is provided on its inner face with a recess 8 from which extend the guides or tracks 9. The forward end of the rest bar 6 may have any desired contour but, in the present instance, I have shown the same as having a rectangular shape as indicated at 10, thereby adapting the same to be seated in the recess 8, while the opposite end of the rest bar 6 is slotted, as is indicated at 11, thereby adapting the same to interlock with the lug 7 and rest upon the reinforcing rib 5, as will be clearly understood by reference to Fig. 5.

The rest bar 6 is preferably provided with a boss or enlargement 12 which is apertured as is indicated at 13. 14 designates curved ribs extending from the rest bar 6 and preferably integral therewith and forming tracks and, in the present instance, the same are shown as of the same diameter as the restbar, it being understood that the rest bar 6 is constructed in such a manner that the top and bottom faces thereof are alike in order that the same may be readily reversed when desired, as will be more clearly set forth in the description of the operation.

15 designates my novel grate the contour of which may vary as desired but which, in the present instance, is shown as substantially cylindrical and having the central bars thereof removed. The inner grate members 16 have one side thereof recessed, as indicated at 17, thereby adapting the same to interlock with the journal member 18, which latter is provided with a depending boss or stud shaft 19, which is adapted to extend into the aperture 13 of the rest bar 6 and be jonrnaled therein. The journal member 18 has its side walls 20 faced off in order to adapt the same to engagewith upper and lower faces, as is indicated at 25, which preferably form an integral part of the grate structure. The front end of the grate is provided with the outwardly extending grate members '26 which are connected with a curved bar or bearing 27 provided with an outward extension 28, which latter is recessed from front to rear on its 21), and slotted, as indicated at 30.

It will be understood from the above dccription that the top and bottom faces of the grate bar are constructed in a similar manner so that the same may be reversed when desired.

The purpose of the aperture 30 is to interlock with the draw or shaker bar 31 which is preferably constructed of an integral piece of material and provided with a shoulder 32 on its upper and lower face, in order that such shoulder may be interlocked with the aperture 30, it being seen that the opposite end of the draw or shaker bar 31 is slotted, as is indicated at 33, thereby adapting the same to interlock with a lug 24- carried by the grate The forward end of the draw or shaker bar 31 is provided with an enlarged head 3-1; forming a shoulder 35 and this enlarged head St is preferabl i apertured, as is indicated at 36, thereby adapting the same to be connected with any desired mechanism for actuating the draw or shaker bar 31.

37 is an aperture through the draw or shaker bar near its forward cud in order that any ashes or cinders which tend to travel along the upper surface of the draw or shaker bar will pass through the ash pit instead of passing exterior of the furnace.

It will be seen that the central portion of the journal member 18 is suitably recessed or cut away in order that the draw or shaker bar 31 may pass thereover and be supported thereon.

3S designates the tire cylinder which is adapted to be seated on the base 1 and the lower portion of the tire cylinder is provided with a flange 39 having a groove L0 in its under face thereby adapting the same to be employed without change in conjunction with the usual construction of a base. attention being directed to the fact that the rear portion of the flange 3.), is outwardly deflected, as is indicated at 41, thereby forn'iing an oblong or pouched portion which is pro vided with a groove 4-2, thereby adapting the same to be seated on the outwardly dc fiected portion 4- of the flange 3 of the base 1. The wall of the flange 33) is cut away at its front portion, as is indicated at 4-3, in order to provide a compact construction, it being understood from Fig. 5 that the flange 3 is cut away, as is indicated at ett, in order to permit the travel of the end of the draw or shaker bar 31 and the extension 28 of the grate.

In some cases arising in practice it is advantageous to have an aperture 45 through the flange 41, as seen in Fig. 10, in order that a dust pipe 46 may be connected therewith, as indicated in Fig. 11, said pipe communicating with a pipe 47 which communicates with the upper cylinder 48 in order that the products of combustion may escape therefrom. The base 1 may be mounted on any desired type of a support and, in the present instance, I have shown the same as mounted on a base plate 49 which is depressed to form an ash receiving chamber 50 and provided with a door 51 of any desired type, whereby the admission of air beneath the grates may be controlled as desired, it being understood that in practice the base plate 49 is carried by legs 52.

In the operation of the grate it will be seen that when the draw or shaker bar 31 is moved, in either direction, the bearing members 27 of the grate will travel on the guides or tracks 9 of the base portion 1 while the bearing members 22 of the grate will travel on the flanges or tracks 14 of the rest 6 and owing to the chamber formed in rear of the ash pit beneath the grate it will be seen that the likelihood of ashes or clinkers collecting near the rear portion of the grate, such as occurs in devices of this character, as heretofore constructed, is practically eliminated since such ashes will pass from the grate through such chamber into the ash pit.

In so far as I am aware, I am the first in the art to devise a stove wherein the base portion and the cylinder are provided with an outwardly extending portion thereby forming a chamber in rear of the grate to provide a space outside of the fire Zone of the fire, in order to retain the usual wall or pocket of ashes that remains when taking ashes from the ash pit by the common and usual manner of a shovel and a free circulation of the air along the rear fire line is provided with consequent increase in the life of the grate and its support and the rear portion of the fire pot, and it is to be understood that my claims to such features are to be interpreted with corresponding scope. A

Special attention is directed to the novel location of the dust collar which is at the top of the base ring of the fire pot which is the highest point possible to place a dust pipe in a stove of the type illustrated thus rendering it impossible for the dust pipe to become clogged at any time, attention also being directed to the fact that the cylinder forming the fire pot is constructed in such a manner that it may be employed either on stoves of the usual type or base or in con-.

junction with my novel construction of base as herein described. Special attention is also directed to the novel manner of construction and arrangement of the grate and the other adjuncts coacting therewith, it being noted that the reversible rest bar is constructed in a similar manner on its top and bottom faces so that the same may be readily reversed when desired, the ends of such rest bar being constructed in such a manner that they will interlock with the cooperating portions of the base 1. If it is desired to reverse the grate mechanism it will be apparent that it is simply necessary to slightly raise the outer end of the draw or shaker bar 31 so that the shoulder will be released from the aperture 30 whereupon such draw or shaker bar may be readily withdrawn. The grate 15 may then be removed from the journal member 18 and reversed, whereupon the grate members 16 will interlock with the journal members 18 sothat the bottom face of the grate will now be come the top face and will present a new grate surface for the bed of fuel. The rest bar 6 is also given the same conformation on its top and bottom faces in order that i may be readily reversed when desired.

It will be apparent that in the broad scope of my invention the contour of the base and of the cylinder is immaterial as long as the base and said cylinder are extended to provide a chamber in rear of the grate and thus provide a free circulation of air to such point at all times. It will also be apparent that the dust aperture 45 may be closed in any desired manner and in some cases arising in practice it is unnecessary to employ the same and this may be dispensed with if desired.

It will be apparent that by employing the chamber in rear of the grate, as herein disclosed, the support or journal for the grate rest is located in such a position that it is not liable to become affected by the heat of the fire.

In rest supports and grates as heretofore constructed there has been undue wear on the upper portion of the base and the lower portion of the cylinder owing to the rocking or tilting movement permitted and, in my present invention, owing to the employment of the tracks 14 carried by the rest bar 6 and the guides 9 carried by the base 1, it will be seen that as the grate is rocked back and forth it will travel in a substantially horizontal plane and no binding of the parts is permitted.

It will now be apparent that I have devised a novel and useful construction of a stove which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars Without departing from the spirit or scope of the invention or sacrificing any o'fits advantages.
