Be it ,known that we, FEDERAL C. ADAMS andJosnrir'Pncnovsn, of l(iimzinnati, in the countyot' Hamilton,l and State of Ohio, have 'invented certain new and useful Improvements in Stoves; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, refer- Figure 1 isa perspective view offa stove containing our improvements.

Figure 2 is a view of our combinedA duster and blower.

Figure 3is a view-of the back of the stove, showing the hot-air apparatus.

' Our improvements are as follows: F-irst, we make lthe top plate'of the .oven slightly convex above and concave below, and strengthen it by a spiral rib cast upon the top, as shown' in the drawings,- in which the plate is marked A. It is shown in place in fig. 1, detached, and in perspective' in 5, and in section in igs. 6 and 8i The purpose of the curvature of the plate is topermit it to expand and contract upward and downward without cracking, while additional strength is imparted to. it by .the spiral rib x a: xl Second, the fire-back is formed of l:ii-plate having space between it and the front of the oven, so that air may pass under the ire-b'ack through this space and through theholcs z az z at the topfc`r the purpose of supplying oxygen for the combustion of -the smoke and gas, and vpreventing the front of the oven from being overheated. lThe fire-backis also provided vwith projections or lips, u' w u', running ohliqucly from top to bottom upon its front surface, and forming, by their overhanging edges, troughs or spouts for the passageof air from below to'a point at-.or near the holes a z z z, therebylincreasing lthe supply of loxygen without unduly cooling the oven. i This front plate, which is marked B, is shown in perspective in ligs. l'and 7, and in section in gsi and -8. It is made somewhat shorter than the space between the sides. of the stove-to' permit it to expand 'freely in the direction of its length. The side pieces C C, fig. 7, are provided with curved flanges to cover the ends ofthe fire-back and keep it inv place without the use' of catches, and are also curved so as to form air spaces between themselves and the sides of the stove, into-which air is Yadmitted through the openings jv v, and from which it is fed io the re from the open s a, protected by thc ovcrhanging lips t t. 'lhird, the combined dust-er and blower D, iig. 2, is provided with catches or hooks, 'm m., which seize the projections on the opposite sides of the front of the stove. Two of these projections are near the tcp and two near the bottom, one of the top projections being` shown at 1t and the other` at o. When hooked by means of thc top projections, the screen D acts as a blower for kindling the lire, and when attached to the projections at the bottom it act-s as a duster to prevent ashes from ily'ing into the room when fthe' -ire is poked or stirred.A Fourth, the quadrant-shaped doors E E, at the front of the stove, are each hinged at one corner, as shown in tig. 1. Just below the corner is a projection, p, which, when theV door is opened, strikes against the projection r on the stove and limits thc movement. The latter projection also limits" the movement of the door in closing. This arrangement avoids the diicultyof expansion and binding ln slidngdoors, and is much more manageable than doors hinged in the ordinary way. Fifth, the heating apparatus attlle rear of the stove, fornied by the additional between suchplate and the'back plate ot' the stove. the p ipc I, and is conducted away for distribution through the pipe K, at the top.
