T0 ALL PERSONS TO WHOM THES PRESENTS MAY COME:l

Be it known that I, DALLAS KNOWLTON, of Liberty, in the county of Waldo, and State of Maine, have invented anImproved Radiator for a. Stove-Pipe; and do hereby declare the same to be fully described in the following specification, and represented'in the-accompanying drawings, of which- Figure 1 denotes a. longitudinal section, and

Figure 2 a vertical and transverse section of' it.' Y

In the said drawings, A denotes a circular drum or case, provided with an induction-pipe, B,and an eductionpipe, C, arranged so as to project from opposite parts of its periphery, in manner as represented.

Within the said case, and close against one end ofit, is a disk, D, Whose diameter corresponds with or about with the internal diameter of the case A. ,This disk revolves freely within the case,lor projects from an arbor, a, having a bearing, b, at the axis of and on one side ofthe caseyanid'being provided with a crank, b2, as shown in iig. 2. v i,

Two plates, c c', extended from the upper part ofthe periphery ofthe clase, and over the disk, and with respect to the eduction-pipc C, in manner as represented in figsfl and 2. Y

Three curved partitions, f, g, t, formed and arranged with respect to cach other and.the induction and4 educton-pipes and the plates c c', in manner as represented in the drawings,'extend from the inner face of the disk D. These partitions, with the case, form channels, z', le, l, m, which, when the two partitions fg are in contact with the plates cv cf, as shown in fig. 1, constitute one long, tortuous channel, leading through the case, and from the induct to the educ-t thereof. I

By turning the diskD, so as to carry thc partition g against the plate c, as the same ie represented in Figure 3, smoke, when passing through the passage z', will pass from thence into vthe upper end of the passage 7:, and thence into the escape-pipe C, without going through the passages c, Z, m.

`If the disk D be turned, so as to bring the partition g midway between the platesc c', part of the smoke,

coming up through the channel z', will pass directly into the escape-pipe C, the remainder going through the channels 1:, Z, -m,'before entering the escape-pipe.'

'I place a damper, E, in the escape-pipe, to regulate the amount ot" smoke which mayeourse through the radiator. In using this radiator, it is intended to so placcit in the discharge-pipe of' astove as to cause .the smoke, after having escaped from the stove, to pass through the radiator, whose sides will absorb and radiate the heat of-such smoke. I

I claimthc combination and arrangement of the pnrtitionsf, g, le, with the disk D and the druin or case A,

I also claim the combination and arrangement oi' the damper E, with the partitionsf, g, le, the disk D, case A, induct B, educt C, and plates c c', arranged substantially in manner and so as to operate as set forth.

DALLAS KNoWLToN.
