Spccilication forming part of Letters Patent No. 93,929, dated August 17', 1869; autedated July 13, 1869.

To all whom it may conca-n:

Be it known that I, NICHOLAS S. VEDnnR,

of Troy, in the county of Rensselaer, andy ranging within a horizontal extension of the stove, in rear of the main diving and return tlues, and in communication therewith, certain horizontal partitions, forming, in combination with the water-reservoir, fines or passages, through which a circulation of the hot-air currents may be advantageously established, to heat the water in said reservoir, as willV hereinafter fully appear; second, in the special construction of a hinge, by which the lidor cover of said water-reservoir is connected thereto in a most simplev and inexpensive manner, and sothat when raised or open the drippings of condensed steam or water there# stopping` short, however, so as to leave a from will be returned within the reservoir.

In theaccompanying drawings, Figure I is a vertical longitudinal section ot' a cookingstove, showing my said improvement applied thereto. n Fig. II- is a rear cross-sectional elevation upon line 12 of Fig. I. Fig. III is a sectional plan upon line 3 et of Fig. I, under a slight modiiication,to be hereinafter described. Fig. IV is a detail plan of reservoir, with its lid or cover detached and thrown back, so as to show thennder side thereof'.

Likeletters refer to like parts in Veach ofvflue, carrying back to the smoke-pipe F the hot-air currents carried down by the nues D D in a common and well-known manner. Gr is the damper, by which the hot-air currentsare made to descend the diving-fities, or allowed to pass directly out. through -the'smoke-pipe. II represents the rearward extension to re- Its top is formed by an extensionof the'top-plate of the stove, provided with a suitable aperture for the reception of the water-reservoir I.

The vertical depth of the extension is such that it mayreceive about one half of the wateror liuc, H', except as inthe modification shownv in Fig. III, when it only extends around three sides of the reservoir, in which case the reservoir itself is made to form the fourth and rear side of said extension,l as clearly represented.

The chamber H is brought into communication with the diving and return fines D D and E -by proper openings through the back plate of the stove, as shown at i2 'i2 and if.

J J represent horizontal partition plates, dividing the chamberH into upper and lower iues, to determine vthe circulation of the hotair currents therein. They extend across so much of the front of chamber H as is covered by the divin g-lues, and across the ends thereof,

space, jl, for the circulation of the hot-air currents around their ends.

The division-plates between thereturn and diving iues are made to extend across the front partof chamber H' to the water-reservoir, and connect with plates J, as shown at j'l,

so as to divide ,said chamber and'direct the hot-air currents, as will be presently described.

When the damper G is in the position, as shown by full lines in Fig. I, to turn the hotair 'currents down the diving-dues, a certain portion of said hot-air currents will pass into chamber H', by reason of its communication with said iiues, being prevented from directly enteriu g the return-flue by the partition-plates J and 72, and, therefore, obliged to pass along the top of plates J, and around the waterreservoir, until, reaching the spaces jl, they are turned downward and returned, still passing around the waterreservoir to the smokepipe or return-tine, as is clearly indicated by the arrows. During this passage their heat will be imparted tothe water in the reservoir, thereby fulfilling the desired object of the construction.

` The area of the opening i3 to the yreturn-liuc should be contracted to such relative proportion to. the area of the openings 2 i2 to the diving-lines as to insure a proper draft tr establish the above-described circulation.

-covers should be of such character as to admit of the use of any of the ordinary stove-furniture upon said extension.

I will now describe my improved hinge for the cover or lid of ythe water-reservoir.. Said lid is shown at K, and is made in two parts,

though it maybe made in one, if desired.

L' represents semi-cylindrical bosses upon'its hinged edge, and Ll corresponding lugs, with semi-cylindrical notches, upon one side of the reservoir. L2 are lateral projections from lues L1, under which forward hook-projections L3,

from bosses L, engage when said bosses rest within said notches. The bosses and notches form the hinge proper, upon Which the lid swings inopening and closing, though, when in anintermediate position, the same may be readily removed. v

The axis of the hin ge being below the inner face of the lid when closed, when the iid is open the plane of its inner face will stand Within the sideof the reservoir, so that any steam which may condense thereon willfbe returned into the reservoir.

The more surely to accomplish this result, the projections L1 and L2 are, by construction, made to prevent the 'opening ofthe lid farther than slightly beyond the perpendicular, as shown by red lines in Fig. I. p

This construction makesV a very cheap and durable hinge, not liable to get'out of order from rust or corrosion, a difficulty heretofore experienced in the use of commonl hinges in this construction. f

Having thusdescribed my invention, what I claim, and desirel to secure by Letters Patent,

The arrangement of the partition-plates J and jz Within the rearward extension H, form- .ing horizontal ues, and in vrelation to the Water-reservoir I, directing the heated air over
