GRATE.

SPECIFICATION forming part of Letters Patent No. 794,123, dated July 4, 1905.

Application filed August 13, 1904.. Serial No. 220,599.

To (LZZ whom, it may concern.-

Be it known that I, ANGELIOO SARTORE, a citizen of Switzerland, residing in New York city, county of New York and State of New York, have invented certain new and useful Improvements in Grates, of which the following is a full, clear, and exact description.

Briefly described, my invention relates to grates for stoves, furnaces, and ranges, but more particularly the latter; and it consists, essentially, of a renewable burning-surface or fuel supporting portion peculiarly shaped mounted on an axis or spindle permitting of an oscillatory or rotating motion and provided with clearing-prongs and means for locking and dumping, as hereinafter fully described, and especially claimed.

The object of my invention is to furnish a grate the burning-surface or fuel-supporting portion of which when required may readily and in a simple manner be replaced or renewed without molesting the member on which it is supported and to provide novel means for the removal of obstructing ashes, &c., generally-encountered in the shaking or oscillating of a grate. Heretofore grates of this type have either been cast solid, or built up of segments or sections. In the former case it is obvious when the burning-surface has burned out or become otherwise destroyed a renewal of the entire grate device is necessitated, entailing not only needless expense, but considerable trouble, while with the latter construction the renewal or replacing of sections by means of bolts, 8250., is equally inexpedient.

That others may see and fully understand my improvements reference will be had to the following specification and annexed drawings, forming a part thereof, in Which- Figure 1 is a side view of my invention. Fig. 2 is an end view thereof. Fig. 3 is a side view of the fuel-supporting portion of the grate. Fig. 4: is an end view thereof. Fig. 5 is a partial side view of the supporting member of the grate. Fig. 6 is an end view thereof. Fig. 7 is a side view of my locking device.

Similar letters of reference denote similar parts in all the views.

Specifically described, my improvements consist of the supporting member A, provided with an axis or spindle a, the clearing-prongs B, and the renewable fuel-supporting portion (1, and the locking device D. The supporting member A and the clearing-prongs B are shown as being made integral, and I prefer to make them in this manner. The supporting member A consists, primarily, of a spindle a of dimensions suitable to fit supports of the stove or range 6 and is designed to rotate therein. On the fire-box portion of the spindle a, are the prongs B, supported by the arms (Z and forming in cross-section a segment of a circle described from the center of the spindle a, and also affixed to said spindle a and between the arms (Z are the lugs or sockets and f. At the extreme front or door end of the spindle a is provided a hole g and a suitable bearing h for the lever f.

In practice I prefer to cast all the parts of the supporting member A just described in one piece.

The renewable fuel-supporting portion G is provided with a convex fuel-supporting surface, the upper portion of which is flattened and which is adapted to hear at its edge upon the longitudinal bars of the supporting member A. Said fuel-supporting portion C consists, essentially, of longitudinally-arranged bars in, suitably spaced for draft and cleaning and supported by transverse ribs 0, which are provided with projections or arms Zand m, all of said parts preferably being integral. In assembling, the fuel-supporting portion G is tilted to enable the hook at m to enter its recess or opening in f and then brought down, thereby entering the lug Z into its socket e, in which position it may be held bysuitable means, preferablya driving key or pin 0 As is clearly shown in Fig. 2, when assembled the grate, in cross-section, forms a semicircle described from the center of the spindle a and flattened at the top. I do not wish, however, to be limited to the exact proportions or shape of the cross-section here shown, as, for

instance, I may find it advantageous to provide a concave top or flattened sides.

It is essential to provide means for locking the grate when in its normal position and also means to actuate or rotate same when cleaning or dumping. This I have accomplished by the following simple and novel means, in which is a lever fulcrumed at n on the spindle end 7L and provided at its upper end with an indentation or hole 0, which when the grate is in its normal position registers with a corresponding projection 12, afliXed to the plate of the stove 6. is provided a weight g, so arranged as to ordinarily tend to press the lever 7' against the lug p, and thereby lock the grate, as is clearly shown in Fig. 1. An ear 9* is provided for unlocking the device by plunging a rod or poker 8 through the hole 9, as is clearly shown in Fig. 7.

In operation a rod or poker s inserted through the hole .r as aforedescribed, contacts with the ear 1', and thereby releases the lever j and unlocks the grate, which may now by means of the poker be made to oscillate for cleaning or rotate for dumping. \Vhen dumping the grate, should the same be obstructed by either clinkers on the side or unremoved and packed ashes underneath the prongs B furnish means for probing or clearing a path for the grate.

The above-described and preferred form may be varied in non-essential particulars or details without departing from the object or spirit of my invention-as, for example, the prongs B may be made a part of the fuel-supporting portion 0 instead 'of, as shown and described, a part of the supporting member A, &c.

I do not claim, broadly, the idea of a revolu ble or rotatable longitudinal bar-arranged grate; but

WVhat I claim, and desire to secure by Letters Patent, is--- 1. In a grate, the combination with an oscillating spindle having sockets and radiallyextending arms carrying prongs on their ends, of a fuel-supporting portion comprising longitudinally disposed bars suitably spaced On the lower end of the lever 7' apart and supported by transverse ribs and having projections seated in said sockets.

2. The combination with a grate, of an oscillating spind le having radial arms and prongs on said radial arms, with a removable fuelsupporting portion provided with a convex fuel-supporting surface with a flattened top, said fuel-supporting portion being detachably secured to said spindle the edges of the fuelsupporting portion resting on the said radial arms.

3. The combination with a stove having a projection on its outer surface, anoscillating spindle, fuel-supporting means mounted on said spindle, said spindle projecting through the wall of the stove and having a hole in its end, a lever fulcrumed on said spindle and en gaging the projection on the stove and a lug on said lever projectingunder the said hole in the spindle, said parts being so constructed and arranged that when a rod is passed through the hole in the spindle it will impinge on the lug and disengage the lever from the projection, thereby permitting the spindle to be oscillated by said rod.

4. In a grate, the combination with a hori- Zontally-disposcd spindle, said spindle being formed with radial arms, longitudinal bars connecting said arms, prongs depending from said longitudinal bars, and sockets on its upper surface, of a fuel-supporting portion comprising a curved body having spaced bars at each side, the edges of which bars are adapted to rest on said longitudinal bars, said fuel-supporting portion having depending lugs adapted to enter said sockets.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

AN GELICO SARTORE.
