IMPROVEMENT IN COVERS FOR sTOvEs.
Specification forming part of Letters Patent No. 179,327, dated June 27, 1876; application filed April 24, 1876. v v
' especially in relation to heatingstoves for burning wood, to which it is generally applicable; but it is obvious that its use is not necessarily confined tO this class on the contrary, it is equally applicable to all stoves which have swinging covers.
My object in this invention is, first, to provide a more convenient swing pan and top for heating-stoves, which, while making a joint against the escape of smoke and gas, may be opened and shut, or swung olil and on, without raising the pan or top over a liange on the base-top; second, to provide a more perfect joint on a swing pan or top for heating-stoves against the escape of smoke or gas, that shall not be aected by expansion or contraction of the castings in heating or cooling, and which will tit as tight when the metal is cold or at a low temperature as when highly heated. rlhe means for effecting these objects I. shall hereinafter more specifically describe.
In the accompanying drawings, Figure l represents a view, in perspective, of a stovetop embracing my invention, and showing the cover and pan-top partially swung off; Fig. 2, a View of the stove-top plate, or what may, perhaps, be properly styled the top-rim7 or base-top 5 Fig. 3, a cross-section through all the plates when closed; Fig. 4, a view of a portion of the top and cover, showing the locking-key pivot. y
The topplate A of a stove (which, in the example shown, is a cast-iron top of a` sheetiron wood heater) has a shoulder, a, commencing at a point nearing the pivot b, common to all the covers, extending around and ending abruptly at a point, c, a short distance past the front. Gommencing at the point c on the top-plate is a raised lip, d, which extends around said plate to a point near pivot '1), where it ends abruptly. rEhedrawings show the exact construction of this, as well as of the lip e on the under side of the pan-top B,
which lip e commences at a point in the rear part of the plate near the pivot, passes around the front, and abruptly ends at a point coincident with the point c oi' the top-plate before mentioned-that is to say, the lip c of the pan-top B commences at and ends at points coincident with the commencement and ending of the'shoulder a-of the top-plate. It is with this shoulder that the lip e joints or engages, as shown in the sectional view, to form a s moke-tight joint upon the front side, while the bearing of the cover-edge upon' the other side against the raised lip d completes the continuation of the surrounding smoke-tight joint, which is one when the covers are all closed. rIhis raised lip d acts as a stop to the pan-top B, while the cover C is stopped by a boss, j', upon the rear part of the pan-top. The common pivot of pan-top B and top-cover C is at the rear, as shown at b, and suiiiciently removed from the middle of the stove to afford proper swinging facilities, and holds the covers to the stove when swung back, in a manner obvious from the construction.
In stoves which have tops of this class, the pans or tops usually swing onasmooth surface, making no joint against the escape of smoke, or are made to set down over a raised lip or ange on the top-rim or base-top, which makes it necessary to give them a loose fitting, and in swinging them open to raise them up over the iiange, which also makes-it necessary to make the pivot-joint very loose and the pivot very long; also, the ordinary pan or cover being directly over the fire and subject to much greater heat than the outside rim or base-top, they must be made to fit loosely, or the unequal expansion and contraction ofthe plates will cause one or both to break. My method of construction overcomes these difculties, gives a convenient, easy, swinging top or pan, and makes a more perfect'joint against the escape of smoke or gas, which is not affected by the expansion or contraction of the plates.
I claim- 1. In swinging covers for stoves, the topplate A, having upon most of its contact-surface a shoulder, a, and for the rest a raised lip, d, the said shoulder and lip being in combination substantially as described, with a lip, e, of the pan-top B, coincident with said shoulder a, and the rear edge of said pantop being combination of thev top- A; consfructedawith v coincident with raised lip d, for the. purpose of producing a smoke-tight joint, and one which Will not interfere with the easy swinging of the pan or cover.
2. In swinging tops orl pansfor stoves'7 the 3.7The combination of top A, coustructed top B, with lip e, and top C, for the purposes herein set forth and described.
In testimony whereof I have hereunto set my haudLthisBd--day ofMarch, A. D. 1876.y
the shoulder a on a portion of its surface, JOHN A. MARVIN.
with the pan-top BH1-(Lying therlip e on a. portion of its edge, coincident with said topshoulder.
