GRATE.

To all whom t mag/concern Be it known that I, 'ARTHUR A. VALTERS, a citizen of the United States, residing at Sandusky, in the county of Erie and State of Ohio, have invented new and useful Improvements in Grrates, of which the following is a specification.

The invention relates to draft creating devices for fire boxes in stoves or the like, and more particularly to the class of draft con-V ducting grates for stoves or the like.

,The primary object of the invention is the provision of a grate of this character wherein slack coal can be used as fuel, and air will be admitted throughout the entire mass thereof when supported by the grate so as to assure complete and perfect conibustion of the fuel without possibility of -thepufiing or the smoking of the fuel resultant from irregular combustion within y the stove.

Another object of the invention is the provision of a grate of this character wherein the slack coal by reason of the maximum draft will be caused to glow continuously, thereby giving forth constant heat and assuring complete combustion.4

A further object of the invention isthe provision of a grate of this character whichis simple in construction, novel in form, thoroughly/ reliable andeihcient in its purpose, strong, durable, and inexpensive in manufacture. v

With these and other'objects in View, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, villustrated in the accompanying drawing, and pointed out in the lclaim hereunto appended.

In the drawing Figurel is a vertical longitudinal sectional view through astove.'

and grate constructed in accordance with the invention. Fig. 2' is a plan view of the holder for the grate. Fig. 3 is a plan view of the grate. Fig. 4 is a sectional view on1 the line u4-4 of Fig. 1.

Similar`reference characters indicate corresponding parts throughout the several views in the. drawing.

Referring to the drawings in detail, A designates a portion of the body of a heating stove, which is of the ordinary wellknown construction, having a downwardly 'tapered re box B which communicates with an ash pit C formed in the base D of the body of the stove, and this base is supported Specification ofL'etters Fatent.

upon legs E of the ordinary well-known construction for elevatingthcjbody of the stove from the foundation or flooring.

Arranged withinthe fire-box B is a grate so holder comprising a ring or annulus 5 which is formed with. an outer beveled periphery 6 corresponding tothe inner tapering diam eter olf the i'ire box B so as to snugly it withinthe saine, andintegral with and ex; tending from two points at the rearmost -portion of the ring or annulus 5 are forwardly converging supporting 'arms 7 which merge with each other at their free ends, at which point there is formed an upstanding lug 8 for'engagement with a grate herey inafter fully described.

The grate comprises a disk 9 having a central opening 10 and a plurality of radially disposed slots l1 concentrically dis-v posed with respect tothe said central opening l0, while Ilat the peripheryof this disk 9 at intervals are the ser' s of protuberances 12, and this disk is adap ed to rest upon the arms 7 of the holder when the grate is'l placed within a stove. Rising above 'the central openinglO yin the disk 9, andriveted concentricallyabout the same is the outturned annular flange 13 of a hollow conical shaped column 14 having a plurality ofrperforations 15 in staggered relation to each other therein, and this column 14 serves as an air conductor for distributing the draft within the stove throughout the mass of fuel 'handle 17 which extendswithout the body Y A ofthe stove through a vsuitable elongated h opening or slot 18, and by manipulating this handle the disk can be partly turned or reciprocated for the shaking of the grate. It4 will be noted that maximum air will be admitted through the column to the mass of fuel for the complete'and perfect combustion thereof, and especially when using` slack coal, which is dumped upon the grate in the usual well-known manner. y

From the foregoing description, taken in vided with an upstanding lug, the arms and lug being between the planes of the upper and lower edges of the annulus, and a disklike grate mounted for sliding and rotary movement on the lug, and of a diameter materially less than the same dimension of the annnlns.l

In testimony whereof I affix my signature in presence of two witnesses.
