JOHN P. HAYES, OF PHILADELPHIA, PENNSYLVANIA.

OVEN.

Specification of Letters Patent No. 16,143, dated December 2, 1856.

To all whom it may concern:

Be it known that I, JOI-IN P. HAYES, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Ovens; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1, is a transverse vertical section; Fig. 2, a longitudinal vertical section; Fig. 3, a horizontal section just below the top plate; and Fig. 4, a like sect-ion just above t-he lower oven; similar letters on the different figures, indicating the same objects.

My invention relates to those cast-iron ovens which are usually constructed and applied as elevated side ovens in connection with a range for generating the heat, and consists in a peculiar mode of constructing and arranging the draft fines and escape, so as to diffuse the heat more equably around the ovens, and especially so over the top of the same.

Referring to the drawings A, A, are the ovens proper; B, B, the outer casing; C-- the flues, the direction of the draft of which, being indicated by the arrows; D, the escape; and E, the damper. The ovens are both made to draw out of the casing (B), in the usual manner, for the purpose of cleansing the flues, the two sides, top, and back of the said ovens being made of sheet-iron united together, and the sides sliding in grooves in the stationary cast iron plate which forms the bottom of each oven-the usual doors when closed, constituting the front. It has hitherto been the practice to make a dumb flue space behind each of these ovens as well as at one side, and consequently t-he direct draft or strongest heat in such constructions passes first beneath the oven, then up one side, and finally over the top to the escape flue, thereby heating these sides of the oven more intensely than the dumb flue sides; and also in conducting the draft to the escape, over the top surface of the upper oven as hitherto, a perfect diifusion of the heat over the said surface, has not been attained. To remedy th-ese defects, I make the vertical partition plate (f) which heretofore produced the dumb flue behind the oven, with an oblong opening (g,) through it on the side next to the oven, which opening is about one fourth the width and nearly the whole length of said plate, as shown in the drawings-or, of such a capacity as will cause the direct draft (C) which enters from the rangefire, to be dividedv into two currents; the one passing across beneath the oven and up on the side C; the other, along the opposite side (C2) thence behind the oven (C3), and through the oblong opening (g), where it joins the other current (G), and then together as one current (0*) passes between the ovens (A and A); or, (if only one oven exists) over the top of the same to the escape flue (D). This perforated partition (f) is fixed to the back of the movable sheet-iron oven-casing, so as to be withdrawn with it; and, for the purpose of catching the soot and ashes which from time to time become deposited on the top of the oven, I fiX a trough which, being of the same width `as the partition plate its bottoni forms the usual top partition plate which prevents the current from passing upward, and now directs it to the oblong opening (g) and so that when the oven is being drawn out, the soot and dust on top thereof is heaped up by being drawn in contact with the stationary outer front casing (B) until the trough (la.) reaches the same, when the said soot and dust falls thereinto and becomes removed with the oven; thus prevent ing its deposit upon the lower plate of the oven as hitherto. For the purpose of more equably diffusing the heated current, over the top of the upper oven, or the one neXt to the escape, I make the said escape iiue (D), directly over the center of the same, and shut 0H the draft on three sides of the same, byV means of the vertical plates, or partit-ions (F, F, F), so arranged that as the current which comes up from the flue (C7) at the side and passes over the top of the oven, it becomes divided into two currents (C8 and CS) by the said plates, as shown by the arrows, and passing the plates they again unite into one current (C9) and return between the said plates, and thus enter the escape (D) every part of the top of the said oven being thus more equably subjected to the action of the heated draft than by any other arrangement hitherto known or used. The strength or velocity of the heated current or currents, is regulated by means of the damper in the usual manner.

What I claim as my invention and desire catching trough (it) at the back part of to secure by Letters Patent, is as follows, each of the said ovens,substanta11y and for l0 viz: the purpose set forth and described.
