STRAW-BUVRNING ATTACHMENT FoR STOVES.

SPECIFICATION forming part of Letters Patent No. 413,664, dated October 29, 1889.

Application filed April 11, 1889.

To all whom it may concern: 7

Be it known that I, JACOB L. HERMAN, a citizen of the United States, residing at Redfield, in the county of Spink and Territory of Dakota, have invented a new and useful Straw- Burning Attachment for Stoves, of which the following is a specification.

This invention relates to straw-burning attachinents for cooking-stoves; and it has for its object to provide a device of this class which maybe readily attached to any ordinary cooking-stove without injuring or defacing the latter or changing its construction in any respect.

The invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointedout in the claims.

In the drawings, Figure 1 is a perspective view of" my improved straw-burning attachment, showing the same applied to anordinary cook-stove in position foroperation.

Fig. 2 is avertical longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional view taken through the fuel-cham- Fig. 4 is a perspectiveview ofthe fuel-chamb'er detached. Fig. 5 is a vertical transverse sectional view taken through the clamp which connects the straweburning attachment to the cook-stove. I i o The same letters refer to the same parts in all the figures. p

A designates the horizontal ,box or casing, the rear part of which is adapted to rest upon the front end of an ordinary cook-stove, and is provided with griddle-holes B B registering with the front griddle-holes O O in the cookstove D. The rear. part of the said casing A may be constructed without a bottom, or if constructed-with a bottom the latter will be provided with openings registering with the said griddle-holes. The front end of the casing A has a downward extension E, which forms the ash-pit, and in which is arranged a transversely-sliding drawer F, to receive the ashes.

G:G are cleats arranged 1n the casing E which completely covers the said ash-panor The outer end of the slide H is Serial No. 306,910. (No model.)

and with a lug K, and to the side of the easing A is pivoted a door L. The latter is adapted to close the opening at the front end of the slide H, so as to shut off the draft and at the same time prevent the withdrawal of M' designates the fuel-box, which consists of a suitable casing, made, preferably, rectangular in horizontal section, tapering towardits upper end, which is closed and pro Vided at its lower end with laterally-extending flanges O O, and with cleats P P, adapted to support the sliding cover Q, having a suitable handle R.

The fuel-box is provided with several openings S S, covered by means of pivoted slides T, said openings serving partially as draftopenings, and also to en able the rod or poker to be inserted into the fuel-box for the purpose of forcing the fuel in a downward directionwhen it shall be necessary to do so.

' Thefuelfloox is provided with suitable handl'es U U, by means; of which it may be conveniently manipulated.

The upper front side of the casing A is provided directly above the downwardly-extending casing E with flanges V V,-which are adapted to engage the fiangesO of the fuelbox, which latter may thus he slid into position above the combustion-chamber, and retained by means of the said flanges V.

To one of the front upper corners of the casing A is pivoted a locking-strip W, having a hole X at its free end, adapted to engage a pin Y at the opposite corner. This locking-strip serves, after the fuel-box has been placed in position, to retain it securely and to prevent its becoming accidentally detached.

Z designates a slide fitted between the flanges V of the casing A, below the fuel-box, and adapted to be operated independently of the latter. Said slide is located below the locking-strip W, so that the latter, while securing the fuel-box in position, shall not in- .te'rfere with the operation of the said slide.

The latter is provided at its front edge with an operating-handle a.

The combustion-chamber of my improved straw-burning attachment, which consists of the space bounded by the slides H and Z, the grate-bars M, and the walls of the respective casings, is provided with suitably located draft-openings I), covered by pivoted slides c.

d is a hearth-plate, attached to the front wall of the casing, inclined from the ends downwardly toward the center, and provided at its outer edge with a flange e. This is to prevent fuel and ashes from dropping upon the floor.

f designates a turn-button pivoted to the front wall of the casing, and which, when desired, may serve to secure the locking-strip W and the slides Q and Z in position.

g designates a clamp, consisting of a strip of band-iron or other suitable material adapted to be fitted over the rear end of the casing A, which rests upon the cook-stove, and having downturned ends h h, the ends of which are provided with inturned lugs i, adapted to extend under the side flanges of the top plate of the cook-stove, and thereby secure my improved straw-burning attachment in position upon the latter. By the use of this clamping device, which may be readily slid into position over the rear end of the casing A after the latter has been adjusted upon the cookstove, the use of bolts or other fastening devices is completely avoided, and my improved attachment may thus be securely attached without necessity for injuring or defacing the cook-stove.

The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The fuelbox may be readily removed from the casing and filled with straw or other fuel of a similar nature, which is packed firmly in the said box, after which the slide Q of the latter is placed in position. This retains the fuel in the box, when the latter is inverted and slid into position upon the casing A. When this has been done the slide Q is removed and adjusted in the holders k, which are attached tothe front side of the casing E. The fuelbox is then secured in position by the locking-strip, and the device is now ready for operation. The supply of fuel to the combustion-chamber may be regulated by the slide Z, and the draft is from the combustion-chamber between the grate-bars M M, through the casing A, down through the front griddleholes of the cooking-stove, through the combustion-chamber of the latter, and through the stove-pipe to the chimney or exit-flue. It will thus be seen that the products of combustion make the entire circuit of the cookstove before escaping into the chamber, and that the cook-stove and its oven are therefore available for cooking purposes as well as if the fire were made directly in the combustionchamber of the said cook-stove. The capac ity for cooking purposes of my improved straw-burning attachment is consequently equal to that of the cook-stove to which it is applied. The intensity of the heat may be regulated by the draft-openings herein described, and when it 'shall be desired to replenish the contents of the fuel-chamber, this may be done while the fire is burning by closing the slide Z entirely while the said fuel-chamber is removed and filled. Owing to the arrangement of the slide H above the ash-pan, the latter may also be removed and emptied of contents whilethe fire is burning, without danger of cinders or live coals dropping upon the floor.

The construction of my improved strawburning attachment is simple and inexpensive, and it may, as already stated, be easily applied to any cook-stove of ordinary construction without changing the construction of said cook-stove in any respect.

Having thus described my invention, I claim 7 r 1.
