SPECIFICATION forming part of Letters Patent No. 276,597, dated May 1, 188e.
Application filed March 3, 1 893. (No model.)
To all lwhom it may concern:
Be it known that I, FRANK J. KARLESKIND, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Stove- Pipe Thirnbles and F1ue-Stoppers,ot' which the following is a specification.
The objects of -my invention are to prevent smoke, soot, or impurities from the iue having egress in the room, also to avoid the use of nails, wedges, and similar fastenings, to avoid play of the thimble or `pipe in the tine, es peciallyto achievea readyinsertion and proper iit of the pipe in the ue, and when said pipe is withdrawn or not used a self-closure of the thimble orilueopening. I attain these objects by the mechanism illustrated in the accompanying drawings, in which` Figure 1 is a front elevation of my improved thimble and fine-stopper as said parts appear applied to the wall of a room in connection In said iigure the slide door or stopper is shown as having closed the due-opening. Fig. 2 is a similar view, but showing the stopper raised to its highest posi tion, exposing the due-opening. In Fig. 3 the front plate is removed, showing the thimble part only, consisting ofthe rear plate having slot and thimble or sleeve and rivet-holes. Fig. 4 is a vertical sectional elevation, showing a section ot' the stove-pipe in the thimble. the stopper of the latter consequently in raised position, also showing the manner of fastening the parts to the wall and flue and Hush with the face of the ceiling.
Similar letters refer to similar parts throughout the several views.
My thimble, with its frames orhousing and Vself-closin g stopper, is intended as a permanent feature of a wall or stove-pipe flue.
A A' represent the frames, being chiefly a front or face plate and a rear plate. Forming partot' the rear plate,A ,is the thimble properviz., the metal sleeve B-to t snugly in the chimney-flue. (See Figs. 3, 4.) At b this pla-te A' has an elongated slot, and along the ed gesot the plate are made rivet-holes. The front plate, A, has a circular opening, c, in line with the sleeve or thimble, so that the stove-pipe can be inserted into the latter. (See Figs. 1,2,.4.) The upper portion of the plate A is castwlatticed-that is, has the crossing-ridges, with the openings c', through which the portion ot' the stopper can be seen. (See Figs. 1, 2, 4')
d represents transverse and vertical strips i of metal, either interposed between the two pl'ates A A' or cast to project from the face ot eitherplate. (See dotted lines in Figz; also, see Fig. 4.) These transverse and vertical stripsd separate the two plates A A from each other and forni a space, D, between them to accommodate the operation'of the stopper. (See Fig. 4.) The arrangement of these strips d is near the edges ot' all the sides, so as to form transverse and vertical grooves d! around all the top, bottom, and opposite sides ol' the frames A A. (See Figs. 3 and 4.) It is in the groove d that the plaster can be fitted and Y have a holdfast; also, the plaster (see X in Fig.
4) can be brought flush with the face ot' the front plate.
E is the stopper. Thisconsists simply of a plate of sufficient size to close the due-opening. (See dotted lines in Figs. 1, 2.) The stopper E is contained in the space D between the two plates A A. (See Fig. 4.) When the stopper is raised to its highest point it strikes against the upper transverse strip d, occupying the space behind the latticed-faced upper portion, clearing the due-opening for the insertion of the stovelpipe; but when thelatter is withdrawn or removed the stopper, byits own gravity, drops and closes the flue-opening, as shown` in Figs. 1, 3. The opposite vertical strips d d (see dotted lines, Fig. 3) guide the sliding of the stopper, and the opposite or top and bottom transverse strips d estop the stopper at thosepoints. The stopper is kept raised by resting upon the stove-pipe. When the stopper drops it rests upon the bottom strip d. The two plates A A' are placed the one behind the other, having the stopper E between them. 4In this condition rivets e are passed through the plates and the strips d, (see Fig. 4,)
joining the plates and their parts together, asl
The improved stove-pipe thimble and fluestopper is litted in the wall or chimneytlue, as shown. (See Fig. 4.) The thimbleB itself enuters the flue, and rests firmly against the brick wall by its flange B lapping down inside the flue over the brick. Further, the frames or plates A A' are secured to the wall by passing a bolt, F, through the mortar, the slot b being elongated to permit the bolt F to reach the line ot' mortar between the bricks. This done, said boltu is finally fastened by a nut, f, as shown in Fig. 4. The plaster can be made to ll up the top, bottom, and opposite side grooves or spaces between the edges of the frames A A', and hence the whole device can be aflxed to the Wall or flue ush with the face of the plaster.
The operation is simple, requiring only that d the stopper be raised to clear the opening ot' the thimble when the stove-pipe is to be insertedorconnected. Whenthepipeisremoved out ot' the thimble the stopper selteloses the opening.
1. The improved stove-pipe thilnble and tinestopper consisting of the front and rear plates, A A', having space D between them, the front plate having a circular opening, the rear plate having the thimble B proper,l with ange B',
and the interposed stopper E, all combined to operate as and for the purposes set forth.
2. The improved stove-pipe thimble consisting of plates A A', the former having a circlilar opening, c, the latter plate having the thimble B, both said plates riveted together and =having top, bottom, and opposite side grooves formed by the spaces between their edges, by means whereof the said plates and thimble can be filled Hush with the face of the wall or its plaster in line with the tine, as and for the purposes set forth.
3. The improved stove-pipe thimble and tluestopper consisting essentially of the frames or plates A A', the former having a circular opening, c, and the latticed upper portion, c', the latter plate, A', having thimble B,.with its anged rest-plate B', the slot b, the rod fastenin g F, the vertical and transverse interposed strips d, the top, bottom, and opposite side grooves formed bythe space between the edges of the frames, and the sliding plate or stopper E, all combined to operate in the manner-and for the purposes set forth.
In testimony ot' said invention I have hereunto set my hand.
