UNITED STATES CHARLES B. LOVE, OF WATERVILLE, PENNSYLVANIA.

STOVEPIPE ANCHOR.

Application filed March 13, 1922. Serial No. 543,411.

To all whom it may concern:

Be it known that I, CHARLES B. LOVE, a

citizen of the United States of America,

pipe section, the shanks thereof being of a length to extend into the chimney so that the angular members of the dogs will engage with its inner wall, the loosely connected ends of the dogs being associated with novel means for exerting pull on the dogs after they have been anchored or lodged against the inner wall of the said chimney.

A further object of this invention is to produce a pipe anchoring device which can be adjusted for use in connection with chimneys whose Walls are of different thicknesses, so that regardless of the dimensions of the wall, within predetermined bounds at least, the pipe anchoring device will be efficient.

It is a still further object of this invention to produce a pipe anchoring device of the character indicated which can be readily manipulated for exerting tension or pull after the anchors have been set, means being also provided for holding the tensioning device at different positions of adjustment.

With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in elevation of a device embodying the invention showing a chimney in section;

Figure 2 illustrates a sectional view on the line 22 of Fig. 1; and.

Figure 3 illustrates a sectional view of the device on a line corresponding with the line 33 of Fig. 2.

In the drawing 5 denotes a pipe section having a flange 6 adapted to abut the outer face of a chimney, and an extension 7 adapted to project within the flue opening of the chimney. The flange 6 may have spurs 8 which project through a gasket 9 to effect a close joint between the pipe and its flange and the chimney.

A shaft 10 is rotatably mounted'transversely of the pipe and it has a ratchet wheel 11 located preferably exteriorly of the pipe, and the said shaft terminates in any tight handle 12 by which the shaft may be rotated.

A flexible element such as wire or other flexible connection 13 is wound on the shaft and it has diverging ends or extensions 1% that are secured in apertures such as 15 formed in the arms or rods 16. The rods have angularly disposed extensions 17 which preferably extend rearwardly slightly, in order that the extensions may bear against the inner surface of the chimney at or near their ends. The members 16 and 17 constitute a pair of dogs or anchoring elements. The preferred arrangement of the parts is shown in Fig. 2 and it will be apparent that by the rotation of the shaft, the flexible element 13 may be wound thereon to exert a pull on the dogs which comprise the rods and their angular extensions and by the release of the pawl and a reversed rotation, these anchoring elements can be released.

A detent or pawl 18 is pivoted on the stud 19 anchored in the pipe section and in a position to cause the nose of the pawl to engage the ratchet wheel 11 so that the shaft will be held against rotation through this arrangement.

The clamping elements may, of course, be formed from rods or other like metal elements of proper dimensions, and the construction of the device will be comparatively inexpensive, whereas its efficiency will be appreciated by one skilled in the art.

The structure shown provides a pipe section for an opening into the flue of the chimney which is adapted to have attached thereto a section of a stove pipe, either interiorly or exteriorly. The flange limits the inner movement of the pipe section and when tension is exerted on the flexible connection the dogs will be caused to impinge against the inner Wall of the flue about the opening. In use, the pipe section is c0n1- paratively short and the dogs 'or angular members may be positioned as desired by hand and Will be held in such position by a pull upon their forward ends through the flexible connection Which is Wound upon the shaft When turned.

I claim:

A stove pipe anchor comprising a stove pipe section, a shaft journalled therein,

means for holding the shaft at different positions of rotation, a flexible connecting element wound on the shaft, and having diverging extensions at its free end, and independently adjustable anchoring elements loosely oonnected .to the diverging extensions, the anchoring elements consisting of rods each having a lateral extension at its outer end.

CHARLES E. LOVE.
