FLU E-CAP.

$EECIFICATION forming part of Letters Patent No. 538,647, dated April 30, 1895.

Application filed October 30, 1891. Renewed October 6, 1894. Serial No. 525,160. (No model.)

To all whom it may concern;

Be it known that I, FREDERICK E. I-IEINIG, of Louisville, in the county of'Jefferson, in the State of Kentucky, have invented new and useful Improvements in Flue-Caps, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in flue caps and consists in certain details of construction and arrangement of parts, all as hereinafter more particularly specified and pointed out in the claims.

In the annexed drawings similar letters of reference denote corresponding parts in all the views,in which- Figure 1 is a rear elevation of my improved flue-cap. Fig. 2 is a top plan view, partially broken away, of the same with a stovepipe projected therein as in use. Fig. 3 is a side view of the frame composed of two parts, which I use to support the movable door of my flue-cap. Fig. 4 is a broken view of one corner of the frame, showing the pintle-bearings for the door of the same. Fig. 5 is a section of a portion of the door through the center of the tongue or stop. Fig. 6 is a perspective view, on a smaller scale than Figs. 1 and 2, of the door with the stop in operative position. Fig. 7 is a detail view of the stop and its spring-support detached from the door.

I use a quadrangular frame with slightly beveled sides as the main shell of myvdevice in which are cast the sockets or bearings cin which are held the pintles dof the door hung in said frame.

At the lower side of the frame A- I provide a stop b which holds the door D normally closed and which must be overcome by lifting the door D out of engagement therewith before the door may be opened for the insertion of a stove pipe in the opening shown by the dotted circular line in Fig. 1, which represents the opening provided through the face plate B- through which the pipe is inserted.

I find that it is essential to cast the pintle bearings --cc integral with the frame A partiallyopen so as to obviate the necessity of using a core in making the casting, and

the face-plate -B- abutting against the said bearings will be sufficient to form a side wall for the same on the outer side and thus hold within said bearings the pintles of the door D which are inserted therein before uniting the two parts of the frame for. use.

By making the frame in two parts as represented and uniting them by means of bolts or screws they may be readily separated for shipment and storage.

On the inner wall of the quadrangular frame A- is a stud s which is either cast solid with the frame or may be formed separately and then united to said frame by means of the same bolt which is used on that side to unite the two parts of the frame for use. This stud s is provided so as to form a stop to limit the inward movement of the door -D and hold it at substantially a right angle to the front of the face-plate, so that the stop or tongue h on the outer side of the door -D will lie in the path of a stove pipe projected through the opening in the same, and stop a stove pipe at the proper position to insure the best draft when said stop his thrown out at right angles to the door -D as shown in Fig. 2 of the drawings.

At the lower side of the quadrangular frame A I provide the two legs eewhich serve to properly support the whole while it is being bricked into the chimney for use, said studs being shown in dotted lines in Fig. 1, and in full lines at Fig. 3.

From an inspection of Fig. 2 it will be seen that the door D is provided with a spring held in hinge fashion. Lever or tongue hwhich is provided with pintles p is held by bent ears of the spring or plate n in such position that when it is opened at right angles to the door -D- it will lie in the path of a stove pipe thrust into the opening provided for its reception, and will be held in position so as to prevent an excessive inward movement thereof so as to interfere with the draft of the chimney. Forming the stop or tongue -hof sheet metal allows me to close the same into the face of the door when itis shut and causes the same to lie flat and not project into the room in an unsightly manner as is the case Where the equivalent of the tongue is in a rigid piece cast to the door D as I have sometimes made it.

It will be apparent that the frame A- may be used with face plates provided with holes for the stove-pipe of different diameter and it is only necessary to provide one set of patterns for the said frame and have as many patterns for the face plate as may be required by the varying sizes of the openings intended to be left for stove pipes of different diameters. I I am aware that flue-caps provided with pivoted gravity bales to limit the inward thrust of a stove pipe projected through the opening intended therefor are not new, and also that a stove-pipe thimble provided with a reducing ring and ventilator cover,,each provided with catches or pins, which catch or engage with a perforation of the stove-pipe at its upper side, for the purpose of retaining the stove-pipe in a predetermined position,isnot new. These I do not seek to claim, but

What I claim, and desire to secure by Letters Patent, is-- 1. In a flue cap, the combination of aframe, a thimble door swinging inwardly thereon, and a stop carried by the door capable of outfQr-Iimiting the inward thrust of the ward projection therefrom so as mice in the path of the pipe to act as a stop folithe same, substantially as described.

2. In a flue cap, the combination of a frame, a thimble door swinging inwardly thereon, a, stop on the frame arranged to abut against the door to limit its inward swing, and a stop 5 carried by the door capable of outward prol jection therefrom so as to be in the path of the pipe to act as a stop for the same substantially as described.

3; In a flue cap, the combination of a frame, a thimblddoor swinging inwardly. thereon, and-a stop, pivotally supported on the door, P P

substantially as described.

4:. In a flue cap, the combination of a frame, a thimble door swinging inwardly thereon, and a stop, spring-supported on the door, for limiting the inward thrust of the pipe, substantially as described. In testimony whereof I have hereunto my hand this 28th day of October, 1891.
