JOSEPH E. DAMAN, OF ST. LOUIS, MICHIGAN.

STOVEPIPE ANCHOR OR LOCK.

Specification of Letters Patent.

Patented May 9, 1922.

Application filed November 17, 1917, Serial No. 202,669. Renewed March 30, 1922. Serial No. 548,190.

To all whom it may concern:

Be it known that I, JosnrI-r E. DAMAN, a citizen of the United States, residing at St. Louis, in the county of Gratiot and State of Michigan, have invented new and useful Improvements in Stovepipe Anchors or Locks, of which the following is a specification.

This invention relates to improvements in a flue pipe :for stoves, and an object of the invention is to provide a simple and effective means for sustaining a pipe in the flue opening in the chimney.

WVith the above and other objects in view, the improvement resides in the construction, combination and arrangement oi": parts set forth in the following specification and falling within the scope of the appended claim.

In the drawing:

Figure 1 is a fiue pipe constructed in accordance with the present invention, and illustrating the same applied, the chimney being shown. partly in section,

Figure 2 is a longitudinal sectional view, and

Figure 3 is a transverse sectional view apthe same is provided with a longitudinal opening that is normally closed by a hinged door 4, the said door having its edge opposite that provided with the hinge formed with a spring catcho for normally retaining the door in closed position. By this means it will be noted that access may be obtained to the pipe 3 so that soot may be readily removed therefrom.

The end of the pipe received in the flue opening 2 is tapered, as indicated by the numeral. 6. Having their inner ends secured in the pipe, inward of the tapered end 6 thereof, is a plurality of angularly disposed flat spring plates 7, which project through the reduced end of the pipe. These spring plates in their outer portion are slitted longitudinally and transversely, the transverse slit being arranged in the end of the p pe 3, and the metal bounded by the slits being bent or rounded outwardly providing a plurality of spring-gripping elements or tongues 8. The tongues 8 are designed for frictional contact with the pipe opening in the flue and the inner ends of the said tongues are limited in an outward direction by contacting with the flared or tapered end 6 of the pipe 3.

Arranged upon the pipe 3 adjacent to the tapered end thereof is a collar member 9, and the inner face of this collar member which is adapted to contact with the chimney breast is provided with a facing of compressible fire-proof material 10, such as, for instance, asbestos.

The pipe 3 at a suitable distance from its tapered end has secured thereto spaced straps 11 bent upon themselves to provide eyes 13 and secured to the pipe by elements 12, In one of the eyes is the end of a coil spring 1st which surrounds the pipe and which is adapted to exert a pressure against the collar 9 to force the same into contact with the chimney breast. It is, 01 course, to be understood that the spring 14 is comparatively weak; that is, the said spring is of a less strength than the spring fingers which engage with the wall provided bythe opening in the chimney breast, the function of the spring 1-1 being merely to force the collar 9 and its fireproof facing at all times into contact with the chimney breast.

The eye members 13 are employed to facilitate the connection. 0f the spring 14 to the pipe section 3, only one eye member in reality being necessary. The spring plates 7 have their inner ends secured to the pipe section 3, and the remaining portion of the said plates is free of connection with the said pipe section. The plates are of spring material, and consequently will exert a pressure in an outward direction, or against the flared end of the pipe section. The curved or rounded tongues 8 have their inner ends arranged inward oi the flared end of the pipe section. 3, and consequently contact with the inner surface of the said flared end. The curved spring members 8 are assisted in their contacting engagement with the wall of the pipe opening by the body of the spring members 7 and consequently will effectively retain the end of the pipe section in the said opening. However, the ends of the tongues being arranged inward of the flared end of the pipe section will permit the ready withdrawal of the said section from the pipe opening.

Having thus described the invention, what I claim is:

A means for holding a stove pipe in a chimney flue opening, comprising, in combination with a stove pipe having a tapered end to be received in the flue opening, longitudinally arranged spaced fiat spring plates having their inner ends secured in the pipe inward of the tapered end thereof and their outer ends extending through the tapered end, and said spring plates having each an In testimony whereof I afiix my signature. 20

JOSEPH E. DAMAN.
