Specification of Letters Patent.

Patented June 8, 3215.

Application filed December 1a, 1914. Serial no. 877,089.

To allwhom it may concern.

Be it known that I, FRANK SMITH, a citizen of the United, States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My invention relates to improvements in stoves, and more particularly to an attachment to replace the ordinary tops'of stoves; and one object is to provide a device'of this character having an internal arrangement whereby equal distribution of heat throughout the top of the attachment is bad, thereby rendering it especially desirable for laundry, cooking, and heating purposes, and efiecting economy of fuel.

A further object is to provide a device of this character having a fiat top of larger area, than the stove top it replaces, so that it can readily accommodate wash-boilers, fiat-irons, cooking utensils, etc.

@ther objects of the invention will hereinafter appear, and in order that said invention may be fully understood, reference will now be made to the accompanying drawing, in which Figure 1 is a front elevation of a stove provided with my attachment. Fig. 2 is a vertical longitudinal section of the attachment and the upper portion. of the stove. Fig. 3 is a vertical cross section of the attachment on line III-JET of Fig. 1. Fig. 4 is a plan view of the attachment with its top plate removed. Fig. 5 is an inverted plan view of the top plate of the attachment. Fig. 6 is a plan view of an inner chamber constituting partof the invention.

A designates a stove of ordinary construe tion with its usual top plate removed.

1 designates my attachment which is substituted for the top plate of the stove.

2 designates an outer chamber of the attachment, consisting of a bottom wall 3 and a surrounding side wall 4, preferably, of elliptical form as disclosed by Fig. 4. The front portion of the side wall 4 has a forwardly extending hopper 5 through which fuel may be fed to the fire-pot of the stove A. The hopper 5 is normally closed by a door 6, operably connected at its upper end to a top plate 7. The rear portion of the side wall 4 has a bay 8, for communication with an outlet 9 in the rear portion of the top plate 7. p

10 designates an inner chamber surrounded by a concave inner wall 12, which flares upward to its juncture with a surrounding side wall 11, as disclosed by Fig.2. The side wall 11 is of substantially the same contour as the side wall 4, from which it is spaced to leave an intervening continuous flue 13, formed by the walls a and 11, the bottom wall 3 and the top wall 7. A dead space 12 is left between the walls ll and 12,

and as it is closed at its ends no draft or circulation of air passes therethrough.

The

chambers

2 and 10 are provided at their bottomportions with registering openings 1d and. 15, respectively, preferably, of ac circular form and communicating with the upper open end of the stove A, as disclosed by Fig. 2, for the free upward passage of the products of combustion from said stove The inner chamber 10 is provided at its front and rear sides with outlets l6 and 17, respectively, which counicate with opposite sides of the fine 13. The outlet 16, is, preferably, left open at all times, but a valve 18 is provided to close the outlet 17 1 when desired. The valve 18 is fixed to a pintle 19, journaled in the walls a and 11, and provided at its outer end with a handle 20. The valve 18 is reliably held in open or closed position by a coil spring 21, bearing atone end against the handle 20 and at its opposite end against a lug 22 on the wall 4.

The top plate 7 is reliably secured upon the walls 4 and 11 by lugs 23 and bolts 24, the former being suitably secured to the wall 4, while the latter extend through holes 7*, in the top plate 7 and through said lugs 23. The top plate 7 is further held in place upon the walls 4 and 11 by depending

ribs

26 and 27 engaging the upper portions of said \walls 4 and 11, respectively. The top plate 7 is provided with removable lids 28 and 29'to leave openings for the reception of a wash boiler, or cooking utensils.

The attachment 1 is secured to the top flange B of the stove by two bolts 25, extending through registering holes-in said flange B and the

walls

3 and 12, as disclosed by Eig. 2. The attachment is centeredu n pipe C.

did

is, preferably, left open, so that the products of combustion may pass directly out into the stove pipe C through the outlets 17 and 9.

When the fire'is well underway the valve 18 is closed, so that the products of combustion after passing upward and heating that ortion of the top plate covering the top of inner chamber 10, will pass out through the outlet 16 and into the flue 13, where it divides and flows in opposite directions through said flue to the outlet.9.- Thus it will be-seen that the top plate'is heated in .a uniform manner throughout its area and will quickly heat flat irons,- or other domestic utensils laced thereon. When desired one or both lids 28 may be removed to admit of the passage of the lower portion of cooking utensils in there'sulta'nt openings, and when it is desired to expose the bottom of a wash boiler directly to the heat inv the chamber 10, the lid 29 is also removed.

From the foregoing description it is apparent that I have produced an attachment for stoves which may be manufactured at 1 comparatively low cost and possesses the features of advantage above enumerated, and while I have shown the preferred construction, combination and arrangement of parts, I reserve the right to make such changes as roperly fall within the spirit and scope o the claims.

Having thus desc bed my invention, what I claim and desire to secure by Letters Patent, is: a
