HEATING APPARATUS.

Specification of To all whom it may concern:

Be it known that I, N. D. MnuLLs, 01": Hartford, in the county of \Vashington and State of isconsin, have invented a new and useful Heat-Controlling Cylinder; and I do herehy declare that the tollowii'ig is a full and exact description thereof, reference heing had to the accompanying drawings and to the marks and letters thereon.

To enable others skilled in the art to make and use my invention, 1 will proceed to descrihe its construction and operation.

()f the drawings forming part of this specification, Figure 1 is an isometrical view of the cylinder, with a part of its exterior or shell removed, showing the arrangement ot means within the cylinder; l ig. is a transverse sectional view; Fig. 3, a top or end view; and Fig. l. a full length side view.

Like letters and marks indicate like parts in all the figures of the drawings.

The object of my invention is to prevent the tree or rapid passing onward ot' the products of combustion from the tire-hex into the chimney or escape line, and thus to economize the consumption of fuel.

It is Well known that in heating huilding's and apartments hy stoves and like means. a large part of the heat generated is lost 31y having too direct and rapid passage thioug'h the pipes and lines. Various plans have been suggested and tried for the cc'irrecting of this evil, among the more common of which are certain arrangements of pipes and joints, and plates and chamhers, looking to the extending of the metal snrtace exposed to the products of conilnlstion. These arrangements are expensive and occupv very conside ahle space. It is, therclore. very desirahle to have some means which shall he etlective, of moderate cost and which will he compact. l\ly cylinder. it is helieved, possesses all the e qualities; and while it i specially designed to he used witl stoves. as will readily he perceived it may he applied to any other means designed for conducting and ditl'nsing heat.

I attach a series of disks of metal (ll, ll, R 1 to a har ((I hy rods (1/) which pass through holes in the shoulders or projections on the har and which allows i each disk a hinge motion on the bar. Each disk is centrally suspended on a. rod (c) the ends of which fit into holes in bars (F, These hars (F, F), as will he seen with the rods (c) constitute a frame for holding the disk and the bar (0) a movable bar for op- Letters Patent No.

crating the disks. \Vhen the disks are thus attached to the bars (F, F, C), they are placed within the cylinder (A) the bars (F, F,) fitting in the grooves of the cylinder, as shown by Fig. 2. The rod (K) is then passed through a recess in a plate attached to the disks (ll j, as is common in stove danipers, and hy the thumb piece of rod (K), through the bar (C), the entire series of disks can he moved. The ends of the cylinder (A) are made conical as at. (ll) and then cylindrical again as at (t) and l) to admit of the cylirnia1=r heing connected to the stove or other pipe. Portions of the periphery of each dislare removed as shown at (l), or in place of the removal of such scmi-eylindrical piece a crescent shaped piece may he removed. and as is shown by Fig. l of the drawings thus making an opening or channel alternating trout one side of the cylinder to the other. lly this arrangement of disks within the cylinder it. will he noticed that in case of injury to any one of the disks or the hreaking ol one, or of any one of the bars or rods, the whole as a structure may be taken t out. ol the cylinder and the broken part being replaced the whole can again be readily returned within the cylinden thc change being as easily ctlectcd as the removal of an ordinary damper. This arrangement of means, it will he perceived, allows of an uninterrupted llow of the gaseous products of comlmstion through the cylinder when the disks are so turned as to he in a line parallel to the sides of the cylinder, and of more or less interruption due to the position of the When the are at right angles to the sides of the cylinder the track of the product will he in a serpentine line, as is shown hy Fig. i, and the cylinder is then a. very ell'icient. heat radiator and diflnser.

The passage ot? the products of comhustion and the escape of the heat can, therefore, \ery tully and readily he controlled.

l claim-- A heat. controlling cylinder in which the regulating disks, shaped as descrihed, are connected with a detachahle frame, the same lacing arranged and operated as hereinhefore specified. i
