SPECIFICATION forming part of Letters Patent No; 298,986, dated May 20, 1884.

Application filed November 9, 1883.

To all whom it may concern:

Be it known that I, ERNST J. KRAUSE, a citizen of the United States, residing at Garlisle, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Cooking-Stoves, of which the following is a description.

Figure 1 is a plan View. Fig. 2 is a longitudinal vertical section through line w x of Fig. 1. Fig. 3 is a vertical transverse section through the line y y of Fig. 2.

In the use of cookingstoves in the summer time it is generally the case that a much larger fire is made than is needed, and this involves not only an unnecessary and wasteful use of fuel but creates a degree of heat in the house which is a serious objection. \Vith a view to remedying this evildetachable partition-plates have heretofore been provided for confining the fire to a portion of the grate, while a stop or obstruction plate on the other side of the partition from the fire prevents the stove from drawing through the open grate on that side. My invention belongs to this class of devices, and it consists in a partition-plate made with a T-shaped head at its bottom, which is capa ble of being inserted between the gratebars and turned to lock itself down, and in the combination therewith of a horizontal stopplate, havinga braced flange for supporting the partition-plate, as hereinafter fully de scribed.

In the drawings is represented the fire-pot of an ordinary kitchen cooking stove or range, which has a front end, A, a back end, B, an outer side, 0, and an inner side, D, which latter is of less height than the outer side, to

permit the smoke and products ofcombustion to pass over the oven on their way to the smoke-pipe. In the bottom of this fire-pot is the usual rectangular grate E.

F is my partition-plate, which has at its lower end a T-shaped head, a, which is passed sideways throughithe grate-bars, and is then turned until the partition-plate stands cross- Wise the fire-pot and in the middle of the same, so as to divide it into two equal or unequal compartments, the T-shaped head serving to hold the partition down and prevent it from being pulled out of place.

(No model.)

G is the obstruction-plate, which has a flange, b, at one end to rest against the partition-plate and form a support for the said plate to lean against. This obstruction-plate has also a brace, c, that acts as a handle, and the plate, forms an imperforate floor to onehalf of the fire-pot and prevents the draft from coming up through the grate-bars on this side, thus compelling the air to pass through the fuel in the compartment that is being used. By this means it will be seen that while the fire-pot is available for its full capacity in winter, in the summer time its capacity may be reduced onehalf (more or less,) and an efficient draft secured through it, which both economizes fuel and prevents unduly heating up the house.

In making use of my invention I may apply it to any form of stove and any form of firepot, the device being universal in its application and simple and practical in its character.

My peculiar construction of partition is characterized by the following advantages: It is a single cheap casting, and is fastened to the grate without screws or bolts, which are objectionable, because their threads soon become rusted and burned, so that they cannot be loosened. The obstruction plate, with flange b and brace c, furthermore, not only causes the draft to be forced through the fuel but affords a solid backing for the partitionplate to lean against, can be placed at either end of the fire-pot, and the brace 0 forms a convenient handle for its removal.

Having thus described my invention, what I claim as new is 1. The partition-plate F for a fire-pot, having at its lower end a head of less width than the spacebetween the grate-bars, and of greater length than the same, to adapt it to be inserted edgewise, and then turned to catch beneath the grate-bars to hold it in place, as described.

2. The combination, with the partition-plate of a fire-pot, of an obstruction-plate, G, hav ing an upright flange, b, at one end,with handle-brace c, as and for the purpose described.

ERNST J. KRAUSE.
