HEATING STOVE AND FURNACE.

SPECIFICATION forming part of Letters Patent No. 395,852, dated January 1, 1889; Application filed July 27, 1835- Serial No. 172,748. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES L. RI'DG WA Y, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in, Heating Stoves and Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described in my patent, No. 281,795, dated July 24., 1883, for improvements in heatingstoves; and it relates especially to means for supporting the fire-pot wall and for revolving it, and also to means for sinndtancously oscillating the grate and revolving the lire-pot wall.

Referring to the drawings, Figure l is a view in vertical transverse section of a furnace having the features of my invention. Fig. 2 is a front elevation of the base of the furnace, representing the wall of the lire-pot and the device for revolving the same and oscillating the grate. Fig. is a view below the line in .r of Fig. l, with a portion of the wall of the firepot removed to bettershowthe eonscction, enlau'ged, representing the manner of supporting the lire-pot wall; and Figs. 5 and 6 are detail views, hereinafter referred to.

A is the ash-pit; 1-3, the fire-pot; C,the combustion-clnnnber; 1:, the radiator-wall; c, the outer casing of the furnace; D, the lire-pot inclosure or wall, which is like thatdescribed in my said patent in that it has the vertical bars (I and vertical spaces d, the bars being connected at their upper and lower ends. The wall is arranged to be revolved in the chamber d immediately surroumling it, and it is so sustained or supported that it may be turned with very little friction. I have there .t'ore provided in the lower section, d, of the fire-pot wall the annular recess (Z Fig. 4, for the reception of the annular angleplate (1, having the vertical part (1, the horizontal exa I tension or flange d, and the exterior hor1zontal bearing flange or plate (Z is sustained by 61 This plate d the continuous series of balls carried or supported by the annular support, angle-piece, or holder (1, which rests upon the ledge or shoulder d, formed upon the ash-pit plate or wall (7 The halls (Z ex-' tend around the base of the lirepot wall, as rep] sented in Fig. 3, and form a continuous z'mti-lriction support for the plate (Z and the fire-pot wall, and as the balls are held between the angle-plate (l and the angle-plate l they provide a double bearing for the firepot-wall, one bcin vertical, or that which results from the flange (1 0f the plate (1 resting directly upon. the balls, and the other being lateral or horizontal, occasioned by the balls bearing against the vertical portion 11 of the annular angle-plate or rotary supportingrin (1.

The lower section of the lire-pot wall has an inmtrdly-extending lcdgc,E,which acts as a shoulder to receive and support the cylindrical covering piece or ring c, the outwardlycxtciuling flange oru'pper portion, e, of which rests upon the ledge E. ering piece or ring extends downwardly very nearly to the upper surface of the grate F.

The ashes, soot, &c., from the fire will fall to some extent upon the surface of the bearing-tlange d of the plate (1 and the bulk struction. Fig. 4 is a dei ail view, in vertical thereof is removed thereltrom as the plate is revolved through the opening 1), Fig. 4, into the ash pit, enough of the ashes, however, remainin gin the space or joint outside the plate d to pack it suliicientl y to prevent air entering the chamber (1' directly from the ash-pit, while the holes D in the angle-plate d permit the ashes or soot which may sift through the joint from time to time to fall into the ash-pit, and thus prevent them from acciinnulatin and clogging the balls.

The grate F has a central pivotal support, F, resting on the bracket or support f, and is thus :ulzmie'l to be oscillated horizontally thereon. The grate has also a baclnvardlyextcnx lin gar-111,1, resting on the ledge fi Fig. l, and a forwardly-e. lending arm, f resting on the bracket f Figs. 1 and 2, such arms f and f serving as trunnions or pivots 011 which the grate may be tilted when desired. The arm or bar affords means for horizontal oscillation of the grate upon its central support, the arm being engaged by a shaker This cylindrical covin a well-known manner, the extent of the movement being limited by the stops f", which constitute the vertical portions of. the bracket f. The bar carries, also, the pawl G, which is arranged thereon to swing vertically and to engage the teeth g, formed upon the under surface of the part (Z of the supporting-plate d, the pawl being weighted, so that its upper end is always in position to engage with the teeth g.

It will be seen from this description that upon the horizontal movement of the bar or rod to oscillate or shake the grate the pawl G is moved therewith, and that its movement in one direction will cause the plate (1- and the fire-pot wall to be revolved, and that upon the reverse movement thereof the pawl will pass along the teeth to a position to again engage with a tooth automatically, preparatory to again partially revolving the plate and the wall upon the next 'l'm'ward movement of the bar or rod.

It will be apparent that, if desired, the pawl may be held. out of engagement with the annular serrated supporting-plate, and that the grate may then be oscillated without imparting motion to the fire-pot.

It will be understood that I do not herein broadly claim either a horizontally-rcvoluble fire-pot wall or cylinder, an oscillating grate, or a grate which may at will be either oscillated or (lumped, being well aware that such constructions, independently, are old.

Having thus fully describwl my invention, 1 claim and desire to secure by Letters latent of the United States 1. In a heatin stove or furnace, the combination, with the wall of the ash-pit, of a transversely-angular supporting-ring resting upon such wall, a series of anti-friction rollers loosely supported upon such supportingring, an annular support resting upon the antifriction rollers, and an annular or cylindrical fire-pot resting upon the annular roller-supported support, substantially as described.

2. The combination, with the wall of an ash'pit, of an annular support consisting of vertical and horizontal portions, a series of anti-friction rollers resting upon such annular support, supporting-r1ng or double-air gle plate resting upon the series of anti-trim tion rollers and covering the inner surface of the same, and a lire-pot resting upon such angle-plate, substantially as specified.

3. The combination, with the wall of an ash-pit, of a recessed and perforated annular support which rests thereon, a series oi. movable anti-friction rollers which are supported at bottom and covered exteriorl y by such perlorated annular support, a supporting-ring or double-angle plate which rests upon the antifriction rollers and covers the same interiorly, and a tire-pot which rests upon the supporting-ring or double-angle plate, substantially as set forth.
