STOVE.

SPECIFICATION forming part of Letters Patent No. 427,940, dated May 13, 1890.

Application filed April 6, 1888. Serial No. 269,803. (No model.)

To all whom it may concern.-

Be it known that I, NAHAM J. WEIL, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, an d to the letters of reference marked thereon, which form a part of this speciication.

This invention relates to improvements in stoves, and has for its principal object a construction whereby the possibility of the surrounding wood-Work taking fire from the stove in case of accidents is reduced to a minimum. As ordinarily constructed, when stoves have been overturned by accident or otherwise, particularly stoves used upon railroads, burning fuel has fallen out of the stove either through the ash-pit door, the door of the combustion-chamber, or, as more frequently happens, through the smoke flue or chimney, the latter being very easily disjointed or broken when the stove is overturned.

The invention consists in the novel devices and combination of devices herein shown, described, and more particularly pointed out in the claims.

In the drawings, Figure l is a central vertical sectional view of a heating-stove embodying my invention. Fig. 2 is an outside elevation of the front of the stove. Fig. 3 is an elevation illustrating the locking-bolts upon the inside of the door of the fuel-chamber; and Fig. 4 is a vertical sectional view of the latter, taken upon line e et of Fig. 3.

In said drawings, A is the ordinary stove, comprising the combustion-chamber A, door A2, and smoke pipe or chimney A3. The combustion-chamber A is surrounded by the usual metal hood or housing'a., forming an air-space a around said chamber.

B is the grate resting upon lugs h and provided with a shaking-handle B', whereby the grate may be rocked or shaken.

C is the ash-chamber, and C the movable bottom having upward extensions or iianges c on its periphery, so as t0 forni an ash-pan.

Said flanges c may be provided with screw-k threads c, adapted to engage similar screwthreads upon the interior periphery of the opening o2 in the floor of the ash-chamber C,

whereby the said ash-pan may be removably fixed beneath the grate; but other convenient mode of attachment maybe employed, if desired.

c3 is a lug or handle upon the under side of the ash-pan C', whereby the ash-pan may be conveniently detached from the stove, when desired.

D is a slotted sliding damper or register movably secured to the housing a of the stove and adapted to slide in guide-pieces d upon the housing in a familiar manner.

D is a passage leading from the ash-chamber C to and through the housing a of the stove and registering with slotted openings d of the sliding plate D. A guard-plate D2, having relatively small holes or perforations dz therein, is interposed between said damper D and the grate of the stove and is preferably secured removably to the housing a, opposite to and covering the passage D', by screws or other convenient means. It will thus be seen that by the use of the perforated guard-plate D2 and damper or register D any amount of suitable draft may be given to the stove, and at the same time all possibility of the burning fuel escaping from the slotted openings d of the damper in case of accident is prevented.

In order to prevent any fuel from escaping through the doorway in the event of the stove being accidentally overturned and the door opened, I have provided said door with a locking device, as follows: E is a knob or door-handle secured upon the outer end of the stud c, which stud is revolubly secured to the door A2. Said stud e projects beyond the inner face of said door and carries upon its inner end the disk E. E2 E2 E2 arethe bolts, which are pivoted at one end upon the disk E by the pins e and which extend in opposite directions to and through the peripheral flange u? of the door. The housing a of the stove is provided with a raised portion or projection a3, surrounding the opening into the combustion-chamber, and to which raised portion the door A2 is hinged, as shown at a4. This raised portion a3 is also provided interiorly upon three of its surfaces with holes or recesses a5, sufficiently large to receive the ends of the bolts E2, as illustrated. When the door is opened, the bolts will bein the position in- IOO dicated in Fig. 3. lVhen the doorl is closed, the knob E is turned in the direction illustrated by the arrow in Fig. 15, and the bolts will then engage the holes a5 and assume the positions illustrated in dotted lines in Figs. l and 4 and in dotted lines in Fig. 3, locking the door irmly to the stove.

In order to prevent the unlocking of the door readily, I provide a spring-actuated pin or plug F, one end of which plug passes through the door A2 and engages the lug e3 upon one of the bolts E2, as clearly shown in Fig. 3. The action of the spring f is such as to cause the said plug F to constantly press inward to engage said lug e3, and it is obvious that when such engagement exists the bolts E2 cannot be withdrawn from the holes or recesses a5.

Vhen it is desired to open the door, the plug F will be first drawn outwardly against the action of the springf in the direction indicated by the arrow in Fig. 4E and out of engagement with the lug e3. The knob E will then be turned and the bolts E2 withdrawn to within the outer edge of the iiange aQ of the door A2, as shown in said Fig. 3.

The outlet or passage G in the top plate of the combust-iomcliainber A and leading to the chimney A is covered by a perforated guard-plate G. Said guardplate is provided with an extension or handle g, which passes outwardly through the opening g in the housing a and is removably secured in position by means of a thumb-screw g2, which passes through a slot iu said handle g and screws into an extension or lug g3 on the top plate of the combustionchamber A. It will thus be observed that the smoke and gases have outlet through the small perforaiions in the plate Gv', while at the same time said plate is securely held in position and will ei'ectually prevent, in case of accident, the escape of any large particles of burning fuel through the passage G. When the perforations in the plate G become clogged with soot, or Whenever it is necessary to remove the plate G', the thumb-screw ggis unscrewed and removed and the plate G drawn out ot' the stove through the opening g.

It will be observed that when the door A2 is closed the burning fuel will be inclosed within the combustion-chamber in such man ner that it cannot escape therefrom in the event of accident, unless, of course, the accident be the entire destruction of the stove.

I claim as my inventionl. In a stove, a suitable ash-chamber provided with an annular opening, its interior periphery bein g screw-threaded, and a removable boltom plate having peripheral upward extensions or flanges to form an aslrpan, said flan ges being externally screw-threaded to en,- gage the screwthreads of the ash-chamber, substantially as described.

2. A stove-door provided with a plurality of radially-movable bolts upon the inner face of the door, adapted to engage the door-frame, said door having also a movable pin positioned to engage one of said bolts when the latteris in engagement with said frame, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.
