SPECIFICATION forming part of Letters Patent No. 731,336, dated June 16, 1903.
Application filed March 23,1903. Serial No. 149,149. (No model.)
thickness of the walls to which it is to be at-.
tached. It has heretofore been proposed to make the thimble in sections provided with threads, so that the parts could be inserted from opposite sides of the wall and screwed together, and in another form the thimble has been made in telescoping sections held together 'by the aid of springs.
The present invention consist-s in forming the walls of the thimble of deep corrugations, so as to render it expansible and collapsible, and providing means whereby the projecting flange on one end may be removed for the purpose of inserting the thimble in position in the chimney-wall and afterward secured thereto.
The inventive idea may receive various mechanical expressions,'one of which is shown in the accompanying drawings, in which- Figure 1 is a longitudinal section of my improved stovepipe-thimble collapsed. Fig. 2 is a similar view of the same thimble expanded. Fig. 3 is an end view showing the flange, which is permanently attached to the thimble; and Fig. at is a view of the opposite end, showing the detachable flange and the means attaching the same to the thimble.
Referring to the drawings, 1 is a cylinder whose walls are deeply corrugated, the corrugationspreferably being composed of parallel sections in a plane substantially at right angles to the lines of collapse and extension of the cylinder, which sections are connected by curved portions free from angles.
2 is an end flange, whose exterior diameter exceeds that of the exterior diameter of the collapsible cylinder 1 and whose interior diameter preferably equals or is slightly less than the interior diameter of the said collapsible cylinder. This flange2 is secured in any suitable way to one end of the collapsible cyl- 'inder and may be permanently or rigidly secured thereto, if desired. 3 is a flange on the "opposite end of the collapsible cylinder, and
means are provided for detachably securing said flange to the end of the cylinder. One convenient means for thus attaching the flange to the cylinder is illustrated in Fig. 4. The interior diameter of the flange has enlarged or cut-away sections 4 on diametrically opposite sides thereof, and corresponding wings 5 5 are formed on the end of the collapsible cylinder, which wings 5 5 are diametrically opposite each other, and a diametrical line fromthe exterior of one wing to the exterior of the other exceeds the diameter of the collapsible cylinder at the portions 6 6, which are not cut away.
The operation of the device is as follows: When the thimble is to be inserted in the opening in a wall, the flange 3 is removed therefrom, and the end from which it was removed is pushed into the opening in the wall and is drawn through the opening until the flange 2 abuts the wall on the opposite side,
and the collapsible cylinder is then extended until the wings 5 5 are drawn out of the opening far enough to permit the flange 3 to be placed over them in the position shown in Fig. 4, when the flange is given a quarterturn, so as to bring the projections 6 6 and the flange into alinement or register with wings 5 5 on the cylinder, and the pull on the cylinder being released its tendency to collapse causes it to draw theflange 3 firmly against the wall and retain the parts in proper position.
One material advantage of my collapsible thimble is found in the fact that it presents a very large radiating-surface which enables it to readily part with its heat, and thereby avoid the danger of overheating and setting fire to the adjacent portions of the wall.
What is claimed is- 1. An adjustable stovepipe-thimble having a flexible corrugated wall.
2. A stovepipe-thimble having a flexible corrugated wall provided with end flanges, one of which is detachable.
3. A stovepipe-t-himble having a flexible corrugated Wall, an end flange rigidly secured body is formed of a single longitudinally-ex- IO to said flexible Wall, and an end flange depansible cylinder. I tachably secured thereto. In testimony whereof I have signed this 4. A stovepipe-thimble having an elastic specification in the presence of two subscrib- 5 expansible wall. I ing Witnesses.
5. A stovepipe-thimble adjustable as to its JNO. S. BROWNL length and whose body or wall is formed of a Witnesses: single integral piece. 0. H. PAULL,
6. An adjustable stovepipe-thimble whose S. D. COYKENDALL.-
