SAMUEL PIERCE, OF TROY, NEW YORK.

COOKING-RANGE.

Specification of Letters Patent No. 18,055, dated .August 25, 1857.

To all whom it may concern:

Be it known that I, SAMUEL PIERCE, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful improvements in` cookingranges by which the heat is more perfectly distributed and more actively put in circulation than heretofore; and I do hereby declare and ascertain my said invention, reference being had to the accompanying drawing in which- Figure l, is a vertical longitudinal section; Fig. 2, is a view of the under side, with the bottom plate removed.

for this purpose I have devised my new invention; and it consists principally in the arrangement of the currents of the bottom flue and recess or ascending flue between the ovens.

The range consists of a fire chamber a designed for either wood or coal placed at one end of the range, with the usual ash pit below. From this chamber the products of combustion, heat, &c., are conveyed by a top flue b to the other end of the range, at the rear corner of which at c is the exit smoke pipe; a partition plate Z cuts o the direct communication between the horizontal flue b and exit pipe c; in this partition plate Z there is a valve e that opens a direct course to the pipe c, but when closed the course of the current is down on the front half of the side descending Hue f and then along the bottom to the front of both of the ovens 0, 0, they being placed side by side on a level with the fire chamber. The end flue f and bottom flue g are divided into two by a partition la extending from the parti-A tion (l down to the bottom and along it nearly to the front, leaving aspace z' for the course of the current into the other side, whence it returns back and ascending the end flue in the rear division passes off at the exit iue. This is all a common and well known course for the draft in diving iiues, and to it I lay no claim. Between the two ovens o, 0, there is a space p, and I have found if this space is all in one or is divided into two entirely separate chambers by a division plate extending up from L to the top the heat will be unequal therein and inactive in circulation. I therefore extend a partition up nearly to the to-p but leave a space s for the current to pass over from front to back so that the natural draft of the bottom flue will aid in creating a current in the space between the ovens and the circulation will be thus made complete, more evenly distributed, and cause the ovens to bake alike on every side.

Having thus described my improvements in circulating the heat between the ovens of ranges, what I claim and desire to secure by Letters Patent is,

The combination of the recess 29 between the ovens having Ia division plate therein open at the top, with the bottom flue as herein set forth so as by the action of the draft of said bottom flue to cause a circulation in said recess 79 in the manner and for the purpose described.

SAMUEL PIERCE.
