Tl-llii/iBLlE LlD HOLDER.

SPEGIFICATIQN forming part of Letters Eatent No. 680,716, dated August 20, 1901. Application filed June 12,1900. Serial No. 20,100. (No modeLl T all whom it may concern:

Be itknown that I,HERMAN KLING, a citizen of the United States, residing at Larned, in the county of Pawnee and State of Kansas, have invented a new and useful Thimble-Lid Holder, of which the following is a specification.

In chimney-fines having two or more thimbles or stovepipe-openings therein, some of which are closed by thimble-lids, gas will often accumulate in the stove or chimney and explode with force enough to displace the ordinary thimble-lid and drive the soot and dirt through the opening into the room.

The present invention relates to novel means for securing the closure in place so that there is no liability of its being accidentally displaced either in the manner above described or by any other means.

A further object of the invention is to provide means which is entirely independent of the pipe-opening closure that will exert a continuous pressure upon the same to hold it in proper position.

In order that the invention may be fully understood, the preferred form thereof is described in the following specification and shown in the drawings which accompany and form a part of the same, and in which- Figure 1 is a perspective view of a portion of a chimney, showing the invention applied thereto. Fig. 2 is a longitudinal section of the same. Fig. 3 is a horizontal cross-section on the line w x of Fig. 2. Fig. 4 is a detail perspective view of the fastening-plug. Fig. 5 is a detail perspective view of the clamp-arm.

Similar numerals of reference designate like and corresponding parts in the several figures of the drawings.

In the drawings, designates the wall of a chimney, 11 the Stovepipe-opening, and 12 the closure for said opening. WVhile this closure may be of any construction desired, it preferably consists of a sheet-metal cap 13, which is provided on its inner face with the radiating bowed spring-arms 14, the ends of which engage the walls of the pipe-opening 11 and form the means for ordinarily holding the closure in place. In order, however, that the closure may be securely held against accidental displacement, an additional fastening device is provided, which preferably consists of a retaining-arm 15, that is secured at one end to the chimney-wall and rests upon the outer face of the cap 13, thereby holding it in place. This retaining-arm 15, as shown, is generally made of a single piece, which is preferably of spring sheet metal, although it may be rigid and constructed of any material desired. One portion of the arm is bent backwardly, as at 16, and is provided with the oppositely-projecting arms 17, which are curved to conform substantially'to the outer face of the cap 13, whereby a broad bearing is provided upon the latter. The arm 15 is also provided near its opposite end with the circular enlargement 19, which has a central opening 20. In order to secure the arm to the outer wall of the chimney, the fastening device 21 is provided, which comprises a plug 22 and set-screw 23. The plug consists of a hollow shank 24, which is provided upon its outer opposite faces with longitudinal ribs 25 and has its interior opening screw-thread ed, as at 26. This shank is provided with a head 27, the inner face of which is concaved, as at 28, the outer face being fiat and provided at its opposite edges with the upstanding curved flanges 29. The ribs 25 are each preferably provided with a transverse notch 25. The clamping-screw 23 is provided with a threaded shank 30, which screws into the threaded opening of the plug. The head of this screw is flattened to form a broad bearing-surface, and it is further provided with the perforation 31.

In applying the-device a socket is made in the chimney contiguous to the stovepipeopening, and this hole is filled with plasterof-paris or similar material in a plastic state. The concave portion 28 of the head is also filled with the same material, and the plug is then forced into the opening until the head abuts againstthe wall of the chimney. It will thus be seen that when the binding material hardens the plug will be rigidly held in place and cannot turn because of the ribs 25, and the notches being filled with the material the plug cannot be easilypulled from the socket. The arm is then placed in position, with the enlargement 19 arranged between the flanges 29 and the arm projecting beyond the flanges, whereby it is held from lateral displacement. The set-screw 23 is then passed through the opening 20 and screwed tightly down, thereby clamping the arm in place. bear tightly upon the face of the cap and hold the same in place. When the cap is to be removed, the arm 15 is taken oft and the screw 23 replaced, whereupon the opening 31 may be utilized to fasten the wire for holding a stovepipe in place.

From the foregoing description it will be seen that a clamp is provided that will securely hold a closure in place and which may be removed, as desired,when not in use. Furthermore, the device is entirely independent of the closure, whereby it may be applied to any chimney and any style of thimble-cap.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having now fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the class described, the combination with a flue-cap, of a lock comprising a plug secured to the Wall of a chimney and having a projection on its exposed face, a retaining-arm adapted to bear against the cap and have a portion in engagement with the projection of the plug to prevent lateral displacement of the same, and means for In this position the arm will' securing the arm to the plug and in engagement with said projection.

2. In a device of the class described, the combination with a flue-cap, of a lock comprising a plug secured in the chimney-wall and provided with a groove in its face, a spring, one end of which fits within the groove in the plug and the other bears against the flue-cap, and means for securing the spring in said groove.

3. In a device of the class described, the combination with a flue-cap, of a lock comprising a spring-arm, one portion of which is bent backwardly and arranged to bear against the cap, said arm having a pair of oppositelyprojecting arms also arranged to bear against the cap, a plug secured to the chimney contiguous to the flue-opening, and a clamp-screw secured in said plug and clamping the spring arm in place thereon.

4. In a device of the class described, the combination with a plug comprising a hollow screw-threaded shank having an enlarged head, the face of which is provided with a groove, said shank being adapted to be inserted in a chimney-wall with the head arranged against the exterior face thereof and adjacent to a flue-opening, of an arm arranged to bear at one end against the cap of said flueopening and having its opposite end fitted in the groove of the plug-head, and a clampscrew arranged in the screw-threaded shank and adapted to engage the arm.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HERMAN KLING.
