IMPROVEMENT IN TOP PLATE 0F COOKING-STOVES.

TO WHOM 'IT MAY CONCERN:

Be it known thatJ,.JOHN B. CROWLEY, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Cooking-Stoves; and I hereby declare the. following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

This is on improvement in the class of cooking stoves whose top plate projects in rear of the stove body proper, to support a hot-water tank or kettle, called the reservoir, and my inventiouconsists in torming the flue underneath said reservoir by means of a pit or depression cast in one piece with said plate.

Figure 1 is a perspective View of the top plate cast on my plan.

Figure 2 is a longitudinal section of the same, with the back plate and its reservoir inposition, and

Figure 3 shows a modification of my improvement.

In the several figures similar letters indicate like parts, the black lines in each figure representing the improved top plate, and th'ehiue lines representing a reservoir and a back plate.

A represents the top plate, with a customary boiler-opening, B, and reservoir-opening C. D is a pit, cast in one piece with the plate A, with which it unites at rear and sides (I d, andihas an oblong opening in front to communicate with the rear flues of the stove proper. Rising from the bottom of the pit Dis a curved deflecting plate or flue-strip, E, which compels the smoke to diverge towards the sides of. the pit before escaping into the flue F of the reservoir G, and which, in conjunction with the rear side of the pit, forms a continuation of the reservoir-flue F. H is the back plate, having-a lug, 71, through which and the' pit-bottom is introduceda bolt, I, secured by a nut, J. I r I 7 A modification-of the above arrangement, intended more especially for a coal-burning stove, is shown in g Several decided advantages result from the'a'bove form, towit, there is not only a great reduction in weight, material, and cost over the forms now in the market, bu't'the device is also much stronger, and free from receding angles and corners for the formation of eddies and collection of soot; there is a'saving of from two to four bolts, and of the expense and time incident thereto, (drilling holes, &c.,) as well as that of. fitting from four to six joints, liable to leak smoke; 'it is much stronger, neuter, and more compact than the customary forms.

I claim herein as new, and of my inventionv r 1. An extended top plate of a cooking-stove, formed with the pit D cast in one piece therewith, as and for the object explained.

2. The arrangement of extended top A, pit D, and deflecting plate E, as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
