to the flue may also vary, it is necessary to so regulate the opening as to provide a proper draft, independentof any temporarily adjustable features.

large an opening as is found necessary, and

isthen secured permanently by means of bolts or other equivalent fastenings, as 6. Within the arch is a segment 7 the length of this segment have V-shaped inturned arms .S whi ch terminate in pivots 9, and the radius of'these arms 8 is such that. tlie'segment '7 fits closely and moves easily within the arch 3, 10 are stops against which the segment free end of the rocker-arm and extending through the front of the masonry. of the fire-place, the segment may be moved and the opening regulated to any desired degree; In order to adjust the length of the arm so that the operating handle will fit any thickness of masonry, or disposition of tile fireplace, I have shown an'outer extension 12, which by means of clips 13 is slidable upon the part 12. Thus, when the apparatus is to be set, the thickness of the masonry and the distance between the rocker-arm and the front being determined, the parts 12 and 12 are caused to slide upon each other until the proper adjustment is effected. The outer portion of 12- has rack teeth 14: formed upon it, and a ratchet plate 15 is fitted, through which the rack bar passes, and the teeth engage with the edge of the hole in the plate when the baris allowed to drop. By lifting it, the segment may be moved to increase or diminish the size of the Opening, It is desirable, however, to malcethis portion of the apparatus as little conspicuous as possible, and in order to do this it is preferable to extend the pivot shaft 9'through the .side of the fire-placc'wall. In order to do thiseflectively, an extension 9 is bolted, or otherwise secured, to the part 9, and the sleeve 17. These sleeves are adjustabl the fireplace and flue opening must bear to each other, this plate is set to leave asand width of vhich are sutiicient to close the opening Ito any deslred degree. The ends ends may be flattened and looped upon each each other, and are set in the masonry of the fire-place in line withthe turning axis of the segment 7 and the extension shaft 9 passes through these tubes and has fixed to the outer end, a ratchet 18. A-paw1 19 is adapted tov engage with this ratchet, and thus retain the parts in any desired adjustment. The parts 9 and 9 may overlap, and have clamps, as at 13, in which they are slidable, as previously described. When the apparatus is set up, these overlapping shafts are lengthened or shortened, and the clamps finally fixed at the desired distance so that the ratchet-wheel l8 and its pawl will lie close to the side of the masonry and be inconspicuous. By means of a handle 20 fixed to the ratchet-wheel, the latter and its connecting shafts may be readily turned, and thus swing the segment 7 to the desired position to cut olf-or increase the flue open-- ing; and the tubes 16 and 17 being scoped, as shown, may readily be adjusted,

so that the apparatus, being constructed of suflicient size for any fire-place, may be readily adjusted to the particular one Where it is to be used, without. the employment of any special tools, the adjustment being within the ability of any bricklayer or chimney builder. j I

Having thus described my invention, what I claim and desire to secure by Letters Patent'isI 1. The combination wlth a tire-place and the chimney-flue thereof, of a circular metal arch fixed in the upper part of the fire-place,

having a channel registering'with the chimney-flue, a permanent plate to adjust the proportionsof the flue opening, a rockable segment turnable within the arch, and means for independently adjusting it and regulating the flue opening.

2. The combination with a fire-place and I the flue opening thereof, of a circular metal .arch fixed in the upper part of the fire-place,

having a channel made through it-registering with the chimney-flue, means for permanently adjusting the size of said openlng with reference to the -fire-place and flue an independently adjustable damper, said;

damper including a circular segment havinginwardly turned ends, pivots upon which the segment is turnable and forms a radius equal to the curvature of the arch, and means: by which said segment may bemoved to cover;

or disclose the flue opening.

tele- In an apparatus of the character described, a circular metal arch fitting the upper part ofthe fire-place, having a channel registering with the chimney-flue opening, a circular segment having pivots concentric with the segment and arch, means for turn- .moved to cover or disclosea portion of the flue opening, an extension of the pivot shaft, said extension having clamps and slidable uponthe. inner portion of the shaft, a

'ing the segment, said means consisting of ratchet-wheel fixed to the outer end, and a pawl engaging said ratchet to retain the segment 1n its adjusted position.

In an apparatus of the character described, a segmental arch fixed in the upper -part of the fire-place, having an opening! registering with the chimney-flue, a segment fitting the interior of the arch having inwardly turned ends and pivots concentric with the curvature of the arch and segment, an extendible bar and locking clamps in line with the pivot shaft, telescopic tubes through which the extension passes, said devices formingv adjustments to exactly fit the apparatus to any thickness of masonry, a ratchet- Wheel 'fixed to the outer end of the extension, lying close against the masonry and having a handle by whichthe shafts and damper segment may be turned, and a pawl pivoted with relation to the ratchet adapted tohold it in any desired position.

6.-A damper attachment for fire-places, said device consisting of an arch having an open channel, a fixable regulating plate attached thereto, a pivoted segment substantially concentric with the arch, a device forooerating the segment, andmeans to adjust the length of the operating device.

In testimony whereof I have hereunto set my hand in presenceof t'wo subscribing \vit- WILLARD R. CHAMPION. lVitnesses TM. CHAMPION, B. Bhocnsson.
