DRAFT REGULATOR;

Application lfiled J'anuary'l', 1923. Serial No. 613,184.

To all tf1/0m t may concern.'

Be it known that we, JOHN E. McLEoD and ARTHUR J. Hnwrrr, Citizens of the United States, residing at l/Vashington, in the county of TWashington and yState of Kansas, have invented certain new and .useful Improvements in Draft Regulators, of -which the following isa specification.

Our invention relates to .durft-regulating devices and is intended more particularly for use in connection with brooderswfor ponltry to control the temperature therein.

In the accompanying drawings, Aone embodiment of the invention is illustrated and:

Figure 1 isa vertical sectional view of a brooder with our invention installed,

Figure 2 is a fragmentary side elevation in larger scale of the draft-regulating device,

Figure 3 is a perspective view of the smoke damper of the furnace, i.

rFigure 4 is a perspective view of the ydetails of the damper, and

Figure 5 is a side elevation of one of the implements used in connection with the furnace.

Referring particularly to 'Figure 1 of the drawings, the reference numeral repre-- sents a chicken house or broeder with a floor 11 consisting of a thick layer of sand or gravel. rlChe reference numeral 12 represents a furnace which is here-shown in the shape of an inverted conic frustum built of masonry and sunk to about threefourths of its -height into the ground. The top and bottoni of the furnace are open and. the top edge of the masonry is covered. by acastiron ring 13 having a depending lip 14 engaging around the inner edge of the furnace and an upwardly directedv annular flange 114 adapted to engage with aI corresponding fiange 15 on the cover or-lid 16. By this arrangement,the top opening of the furnace is entirely closed. Y

At the bottoni of the furnace, where it is considerably smaller in diameter than at the topa grate 17 is located. Around the top edgeof the grate is a rim 9 about three fourths of van inch in height, intended to keep the coal from blowing of when the grate is removed. Below the grate is arranged an ash pit 18 with an ash pan 19 practically filling the pit. The ash pan is provided ywith handles 2O so that it may be lifted out of the furnace by means of a hook 21 `(see Figure especially provided for this purpose, after the lid 16 and the grate 17 have been removed. The grate 17 may also'be lifted lout by the same hook 21.

At one side of the furnace, aboutniidway between the .grate and the lid, we provide a damper consisting of a slidable door 22 covering the opening of a manifold 23 comn'iunicating with the furnace. As best seen in Figures 3 and 4, this manifold is constrncted of an. upper Yplate 24 and a `lower plate 25 having interengaging flanged sides and back providing tubularoutlets 26 adapted'to engage the flue pipes 2.7 are preferably two in the manifold. here be noted that the iianged sides of the plates will prevent warping of the manifold. The forward side of the manifold is curved to conform to the contour ofthe furnace `into which it opens and the damper 22 is similarly curved and preferably provided with reinforcing ribs 28 and a hinge 29A located at the top edge of the damp-er and in the middle thereof. To this'hinge is pivoted a two-arm lever 129 fulcrumed at 30 yin the housing J31 connected With the manifold in any sui-table manner such, for instance, as by meansof a U-belt 32. This housing consists of two Vinter-engaging plates 33 and 34 and is closed at its rear end by means of an angular bracket 35 provided with a perpendicular pipe A3G forming a `guide for the operating rod 37 which is hinged to the inner end .of .the lever 129V as at 38. The plates 33 and 34 of the housing and the top plate 24 of-tliemanifold, as well as the end bracket 35, are provided with interengaging lugs 136 to form a rigid construction. At the upper end of the pipe 36 is kprovided one or more prongs 39 intended to receive the ear 40 of a clamping handle lever 41 .which embraces vthe operating rod V37. Between the upper end of the .pipe 36 and the lever 41, and surrounding Vthe rod 37, is inserted a coiled spring 42 .which tends to tilt the clamping lever 41 upwardly and in that manner retain the operating rod 37 in any set position. The upperend of the oper-at ing rod 37 carriesa ball forming a grip 43 for hand operation and it will now be seen that by pulling or pushing on the grip 43, the opening or closing of the damper door 22 will be effected by hand, through the intermediary of the lever 129 andthe rod 37. However, inforder to close the damper 22, vthe clamping il'iandle 41 will have to be depressed `to release .its hold on the operating r, of which there It will Cil lli
