SPEGIFIOATZON forming part of Letters Patent N 589,631, dated September '7, 1897.

Application filed March 9, 1896. Serial No. 582,349. (No model.)

To (all whom it iii/(Ly concern:

Beit known that l, UHAUNCEY 'l. ANDREAS, of Bayiield, in 'the county of Bayfield and State of Wisconsin, have invented a new and useful Improvement in HeatingStoves, of which the following is a full, clear, and exact description.

My invention is an improvement in the class of heating-stoves having air-heating tubes or flues arranged in the combustion-chambcr.

The invention consists in the novel construction and combination of certain parts, as will be hereinafter fully set forth, and pointed outmin the claim.

Referen cc is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the stove, portions being broken out to show interior construction. Fig. 2 is a slightly-irregular vertical longitudinal section taken practically on the line 3 2 of Fig. Fig. 3 is a rear elevation of the stove. Fig. at is a plan View of the same; and Fig. 5 is a horizontal section taken near the bottom of the stove, practically on the line 5 5 ofl ig. 2.

In. carrying out the invention what may be termed the framework or skeleton of the stove consists of abase 10, atop 11, and a backplate 12, which extends from the top to the bottom, the outer face of the said back plate being preferably convened, as shown in Fig. 5, and the inner face of the plate being concaved.

The top and the bottom, together with the back plate 12, may be of cast-iron or an equivalent material, and. the top and the bottom, in addition to being connected by the back plate 12, are also connected by means of tubes 13, which tubes extend from the bottom to the top.

Any desired number of tubes may be employed at each side of the framework of the stove. Ordinarily, however, three tubes on each side are 'suilicient, and the said tubes at their upper ends are made to connect with a drum 1%: through the medium of elbows 13, and the said drum is opened at the top when the heat from the drum is to be delivered into the room W1Gl'0 the stove is located; otherwise the top of the drum may be closed, and

apipe maybe connected therewith to lead to an upper story or to an adjoining room.

The stove-tubes 13 are usually made of castiron and fit around collars in the -stove-bot tom and also around collars formed upon the under face of the top of the stove. All the collars surround openings, and the openings in the top are further surrounded by collars upon the upper face of the top plate, adapted to receive the bottom portions of the elbows 13, which are made of planished or Russia iron.

At the front of the stove a plate 15 is located, which may be of cast-i rou, and the said plate extends from the bottom or base of the stove to a point near the top; and the said front pla1'e, as shown in Fig. 5, is concaved upon its front face, and preferably its rear face is GODVGXQCl.

In the bottom or base of the stove an opening 16 is made near the center, through which opening the ashes that may be contained within the I stove may be withdrawn or may escape. At each side of this opening a slideway 17 is made, and the opening is normally closed by a sliding cover 18, having movement in the aforesaid ways 17, and the said cover has a handle 19 secured to it, which extends, preferably, outwardly atthe front of the stove, as shown in Fig. The back Vertical partition or plate 12 is provided at each side of its lower portion with an opening 20, and slideways 21 are produced at each side of each opening to accommodate slides 22, and each slide is provided with a handle 23, which is carried upward and outward through the top of the stove, so that the slides at the back, together with'the slide in the bottom of the stove, may be manipulated from the outside.

A jacket or casing 24 is made to surround the frame or skeleton of the stove, beiu g properly secured to the bottom and to the top of the same. This casing or jacket is preferably made of Russia or planished iron and may be and ordinarily is provided with a steel lining. hen the casin g or jacket is in place, a chamber 25 is formed at the back of the stove between the casing or jacket and the backpartit-ion 12, and the said chamber 25 is virtually a flue. At the top of the stove over the said flue 25 an opening 20 is made, surrounded by a suitable collar 27, as shown in Fig. 41-, the

said collar being adapted to receive a smokethe stove near the bottom portion of the fire.

A substantially horizontal partition 31 is form ed at the upper front portion of the stove, connecting at its inner end with the front partition 15 and constituting a top or cover for the upper portion of the front line 29. This upper partition 31 is carried outward through an opening 32,made in the front portion of the stove, and the said opening is normally closed by a door 33, which has a hinged connection at its upper edge with the top of the stove casting and has a hearing at its lower edge upon the aforesaid horizontal partition 31,and when this door is open the fuel may be introduced through the opening 32 into the interior of the stove. The door is held closed through the medium of a weight 3i, which is ordinarily attached to the upper portion of the door at its outer face by means of a shank 35, and when the door is opened it may be' carried over upon the top of the stove and the said weight will engage with the top portion of the stove and will hold the door in its normal position.

A throat-plate 36 is secured to the front of the stove below the outer projecting end of the horizontal partition 31, and an opening 37 is made in the casing or jacket between the throat-plate and the said partition, communicating directly with the front flue 29, and the space between the said throat-plate and the partition 31 at the front or outer ends of these parts is closed by a draft-slide 38. iVhen the said slide is opened, as shown in Fig. 2, the air passing through the openings in the slide will enter the front fine 20 and will gain access to the bottom portion of the fire through the lower openings 30 in the inner wall of the said front fine.

The most direct course for escape of the light products of combustion is through the opening 39, Fig. 2,which is located in the central upper portion of the rear partition 12, and thence the products of combustion pass into the smoke-pipe 2S. Said opening 39 is provided with a hinged valve or damper 40,

operated by a horizontal rod a1, Figs. 3 and 1. It will be seen that the draft may thus be direct through the middle to the central upper opening 39, as shown by single-head arrows. Fig. 2, or it may be less direct, as shown by double-head arrows, Fig. 5, the products being in such case spread or diverted laterally. so as to come into contact with the opposite series of side flues 13, and hence, the latter being more highly heated, the air entering them is heated correspondingly before it enters the drum 14. Thus when the fuel is fully ignited a comparatively low fire may be made effective for heating the air passing through the flues 13. XVhen the door 33 is open, as shown by dotted lines, Fig. 2, air may be allowed to pass direct through the central upper portion of the casing to the rear opening 3!).

The cold air from the floor will pass up through the tubes 13 and in passing through these tubes will become heated, and the air in its heated state will be delivered to the drum 1% and from thence will escape into the room or wherever it is desired to be directed. The tubes 13 in addition to conducting air to the upper portion of the stove will also serve to prevent the fuel coming in close contact with the sides of the casin g or jacket, and thereby prevent the said sides of the jacket from becoming burned out. \Vhen the ashes or the fire is to be dumped, all that is necessary is to draw the slide 18 in a forward direction, uncovering the opening 16 in the bottom of the stove, through which the contents of the stove will escape. The base of the stove is provided with suitable legs 42.

Having thus described my invention, I claim as new and desire to secure by Letters Patent I The improved heating-stove, comprising a casing,two series of vertical ai r-flues arranged opposite each other within said casing, the rear vertical 0utletflue 25, having the two lateral openings 22, at the bottom, and the central opening 26, at the top, the central airinlet, or fine, 29, arranged at the front,within the casin g, and extending down to the bottom of the combustion-chamber, as shown and described, to operate as specified.
