SPECIFICATION forming part of Letters Patent No. 246,807, dated September 6, 1881.

Application filed April 19, 1881.

To all whom it may concern l Beit known that I, ALBERT S. NEWBY, a citizen ofthe United States, residing at Champaign, in the county of Champaign and State of Illinois, have invented certain new and useful Improvements in Linings for Fire-Boxes ot' Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or igures of reference marked thereon, which form a part of this specication.

Figure l is a top view ot' the device. Fig. 2 is a bottom view of the grate. Fig. 3 is a view ofthe front piece. Fig. 4 is an end view. Fig. 5 is a rear view. Fig. 6 is a vertical transverse section.

This invention relates to improvements in stoves, more 4particularly the grate-linings.

The object ofthe invention is the production of a device whereby a wood-stove can be readily adapt-ed to the use of coal, and a lining formed to be used with different sizes of stoves.

The invention consists in lining for a stove, the lining being made adjustable and made of metal, in combination with some plastic material, all as hereinafter set forth.

In the annexed drawings, A is the bearing of the lining, and is the first part to go into the tire-box.

B B are the side pieces, havin g the reverse aligned bearings l) b for the grate-bottom pintles, the elongated openings b b to let ashes through, the bolt-holes b3 b3 at the front to add on pieces to increase the length, and longitudinal slots b4 at the rear ends for adjustable attachment to the back piece, C, by bolts b5, and rib b7 and stud bs to hold the end pieces of lining. This back piece, C, has the slots c for its own adjustment, and ribs c and studs c2 to hold the lower edge ot' the back of the lining. The ends of the pieces B and C are grooved, as shown at z, so that they can be diminished to suit smaller stoves.

bfi are stops on the side pieces to limit the motion of the bottom. D is the grate-bottom, consisting of two longitudinal ribs, d d, and the right-angled transverse bars d. The ribs d d are narrower than the bars df, and extend (No model.)

below these, as shown in Fig. 6. The bars d are thinner-that is, ot' less depth-between the ribs, thus compensating for expansion or contraction and preventing warping. The spaces between the transverse bars are wider at the middle of the grate than at the ends.v making a better draft where most needed. E vE are the pintles, having shanks e e, with slots e e', which are adjustably secured one to each end of the bottom by bolts F F, which pass through spaces between the bars d d and through slots e' o. The bars forming the spaces which arc to receive these bolts F F are countcrsunk at their top edges, so that the heads of the bolts will be flush with the upper surface of the bottom, and not liable to burn, and can be slipped endwise. The ends of the ribs and bars have the grooves z, so that they may be shortened. This bottom thus constructed can be used with various sizes of lining and can be readily applied.

G is the back, having swell g to receive the plastic, with ribs g to prevent warping, and lugs g2 to hold to the corners, and overhanging lip g3 and grooves z for reducing the size.

H H are the corners, having open slots 7L at the back to receive the hooks of lugs g2, and in front, at top and bottom, the slots h h2 h3. The slots h are open at their outer ends to receive the iins i. The other slots, h2 h3, are closed, the former being straight, the latter curved, as shown.

I I are the end pieces, having tins t' t', iitted to open slots h', and held to the corners by bolts K, passing through slots h2 h3, the curve in the latter giving different pitch to the back. Near the front, in their top edges, these ends have the open slots or seats i yi for bolting to the stove. These end pieces have the grooves z, so as to be made smaller.

L is the front of the grate, having open slots Z at the ends for attachment to the stove, and holesl for bolts, which adjust it to or from the stove-front.

Z2 are depending bars, straight or backward curved. These bars and the ends of front L have the groove-s z, so that the front can be made smaller. This lining, so formed, is to be adjusted to the particular tire-box where it is to be placed by breaking away its edges or adjusting the various parts by their slots and bolts and then put; in place, the front being,` 2.
