W. E. FITCH. FIREPLACE DAMPER. APPLICATION FILED MAR. 22, 1911 Patented Dec.12 ,19l1.
/ ZSHEETS-BEEBTI.
E. FY1303, LQUISVME? UNTUCKYI firnnrnaon-nnm an To-all whom it concern:
Be it known that I, WILLIAM E. Fr roir, a
. citizen of the -United- States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a certain new and useful Improvement in Fireplace Dampers, of which the following is a full,
clear, and exact description. I
This invention relates to dampers of the kind that are built in the throats of chimneys in fireplaces, and particularly to those dampers known in the trade as dome dampers wherein a domedike casting which is designed-to be built in the masonry of the chimney, hasa pivoted damper-door adapt-- ed tobe opened and closed from outside the dampera' In prior constructions the door-actuating mechanism has been arranged outside the damper casting or body and hence,'inaccess1- ble, or, at least accessible only with difficulty, after the damper is built into the chimney.
The object of this invention is to provide for the arrangement of the damper-door- 26 actuating, mechanism Within the damper body, so that itmay be readily accessible for emplacement, removal and repairs without disturbing the setting; and I have herein illustrated one construction which meets these conditions efficiently, but wish to be understood as not limiting the invention to' this precisebonstruction, excepting as the same is hereinafter claimed.
Inthe accompanying drawings 1l1ustrat- '35 ing the invention, in the several figures of which .like parts aresimilarly designated, Figure 1 is a top rplan view of the dome damper, with theqdoor closed, Fig. 2 is a front elevation-of that end of the apparatus which contains the door-actuating mechanism, the operating rod being hroken'oif, Fig. 3 is a cross-section of the upper part of a fireplace and the chimney throat with my damper in place, the damper door closed,
and Fig. 4 is a similar view with the door fully open. Fig. 5 is a perspective view of one end of the door, and Fig. 6 1s a perspective View of the cam-for coiipcrat'ion with the parts shown in Fig. 5 and constituting parts of the herein-referred to door-actuating mechanism.
1 mayreprcsent the upper part of. the fireplace, and 2 the chimney throat.
The damper body comprises, in one casting, the arch-bar 3 and the sloping top or dome 4, open at top and bottom. The side Application and march '22; 191-1. Serial No. 616,245.
Specification of Letters Intent. fatntdDeQ. 12 1911.
or end walls and 6 of the dome may have any suitable bearings for the journals of the door,-preferably an open bearing 7 on one and a'closed bearing '8 on the other; thelattelr being provided-with the cover .9 bolted in p ace. closed hearing has a pocket extension 10 to receive the door-actuating mechanism; the said extension being on the inside instead of the outside of the body and in open communication ,Withthe interior of the body be-' neath the door 11, sothat the door and'the door-actuating mechanism are readily accessible from. within the'fireplace below the body withdutdisplacintg the body.
v The'door 11 hasa anged journal 12 atone end to cooperate with. the bearing 7,
The end ofthe body next to the and, a straight journal 13 at its other end to cooperate with. the closed bearing 8. Near the right-hand end the door has-bolted or otherwise appliedto its under side a lug l4; engaging a'cam slot 15 in the cam.16. This cam is pierced longitudinally at 17 to receive an operating rod 18, and-a set-screw 19 may be used to fix the cam upon the rod.
The rod is long enough to have bearings in the front and back walls of the dome pocket extension 10, andto extend out through the masonry to theface of the fireplace. For
. ornamental and sheathing purposes the rod may be incascd in a brass or other sleeve 20 having a front plate or escutcheon 21. An operating handle 22 is applied to the extreme outer end of the rod and incloses the same, and .is held thereon by a set screw 23;
and this handle may be of a character and so set on the rod as to indicateby its position whether-the damper door is open or closed;
It will he observed that the lug 14 and the cam 16 are arranged within the body, and not outside of it, and while concealed from View, they are readily accessible for setting, repairs,and the like. By loosening the screw 19: the, rod 18 may be withdrawn and then the cam drops off. So, also, by un-- bolting the .iug from within, said lug may be removed, and in either case the door itself -may be slipped from its-bearings in the .dome or body and be removed without disturbing the body. Indeed the connection of the lug '14 with the cam 16 is such that the door may be removed wi'flliou t disturbing the rod or cam, by simply ift-ing-the door from its loose or open hearing 7 and then sliding it lengthwise toward such hearing so as to free the journal at its other end sion IQ of the body, serves to locate the cam' "be omitted or' modified; The end extension'flttocovehthepooket ex-' and-its fr'ont andback mus resist any end thrust to which; the cam may be subjected, but obviously this extension magflf desired,
tension, andthe, lug'lt isfbolted or otherwise fixed to said extensioni24;
- The operation would seem-tqbe obvious, but it may suflioe to state that by'tur'ning the .rod the door .may be"o jenedto' any extent and held so open-bye}; e friction between the lug and the camfuntil by-aire side openmg within the body, a door pi'vverse turn of the'rod the door. is closed.
This-dampendifiers essentially from-prior I constructions in the following, among other,
particulars, namely i Its door-actuating mechanism is exposed inside of. the dome or body, thusima'king it possible to adjust the l damper rod to proper. positionafter: thebody is in place-and to faoilitate'repairs' cation and drawings. i
when required. l.he. door-can'be removed and-replaced atwill .without tearing out the body, so as togive free access to the flue when cleaning out-and repairing. The
damper"may be set with the door in place,-
or'the door may-be "placed' inpositio'n after the body has been installed.
\Vithin my invention 'as hereinafter' claimed; are. variations in structural fea- 'tures' and arrangement, with respect to 'the single illustration contained in the. specifi What I claim is adapted to be set in the masonry of afire-f place and provided with a; pocket. extension at one side opening within the body,.a pivotal door hung in said body, and door actuating mechanism arranged within the pocket extension of the .body beneath thedoor and accessible from within the. .fireplace below the. body without displacing the body. i t
2. A fireplace damperyhavirig a body or has the adapted to be set in the mas'tinry of a fireplace and provided with a pocket extension at one side opening within the body, a .piv-'.
otal door hung in hearings in said body-and 'Q2.P&b16.0f lengthwise movement therein to set -and remove it,-- and a door-actuating mechanism arranged within the: pocket-extension of the body beneath the ;'door, a part of said actuating meohanism"being carried by-the door and the remainder supported- .in the body and the whole accessible from .within-the .fireplace from below the body without displaclng the body or door,
3.-A- 'fireplace damper, having fa body. adapted to=-be set in the throat of a 'himney and-providedwith a pocket extension at one otally andslidably mountedin hearings in said body, a lug applied to the underside "of said door and projecting downwardly' and longitudinally relatively thereto, and a cam mounted within the pocket extension of -thebodymext to the lug and engaging the hav-' the settingand removal of the door without disturbing the body.
