SPECIFICATION forming part of Letters Patent No. 494,342, dated March 28, 1893,

Application filed November 25, 1892- Serial No, 452,976. (No model.)

To all whom it may concern.-

Be it known that I, DAVID MYERS, a citizen of the United States, residing at North Manchester, in the county of Wabash and State of Indiana, have invented a new and useful Improvement in Stovepipe-Thimbles, of which the following is a specification.

My invention relates to an improved thimble for receiving and holding a stove-pipein the chimney.

The object of my improvement is, to provide a thimble having an ornamental frontplate and adapted to be set in the brick-work of a chimney to receive a stove-pipe, and pro vided with means for clamping the pipe in the opening.

The accompanying drawings illustrate my invention.

Figure 1 represents afront elevation. Fig. 2 represents a rear elevation; and Fig. 3 a central transverse section.

In the drawings, A, represents a flat plate having a central opening, B, adapted to receive the end of the stove-pipe 0. Projecting from the back of plate A, is a short tubular section, E, formed integral therewith and having the same internal diameter as and ar ranged concentric with the opening B. The opposite sides of this tubular section are provided with longitudinal slots, F, F, and, arranged on each side of said slots, respectively, is a pair of logs, G, G, and 1-1, H. A pair of bell-crank levers I, I, is pivoted, respectively,

between the lugs G, G, and H, H, the arrangement being such that the end of one arm of each of the levers is pivoted between the lugs, and the arm projects through the slot F into the opening B, While the other arm lies within the tubular section A, so as to leave a narrow space adapted to receive the thickness of the stove-pipe between the inner edge of the arm and the inner surface of the opening.

Connected with each of the levers I, at a point intermediate between the pivot, J, and the opening B, is a screw-threaded bolt, M, which extends through the front-plate A, and

is provided at its outer end with a knob, K, for convenience in turning the bolt. The other end of the bolt extends through the lever and is provided with a nut,L,which rests in a recess in the lever, or is otherwise connected thereto so as to keep the nut from turning.

The operation of my device is as follows: The thimble having been set in the brickwork of a chimney, the end of the stove-pipe is inserted in the opening B, the walls of the pipe passing between the inner arms of the levers I, I, and the walls of the opening. By turning bolts M so as todraw the pivoted arms of levers I toward the front plate, the arms of said levers which-embrace the stovepipe are thrown outward, thus clamping the pipe tightly to the walls of the opening and pressing the portions immediately embraced by the arms slightly, into the slots F, thus firmly securing the pipe against withdrawal from the opening. By reversing the movement of the bolts, the pipe is released.

I claim as my invention In a stove-pipe thimble, the combination of the front-plate having an opening adapted to receive a stove-pipe, and provided with a tubular section extending from one side of the plate and surrounding said opening, the bell-crank lever pivoted substantially as shown anddescribed to lugs arranged adjacent to said tubular section, said lever being arranged to project through the wall of the tubular section into said opening and to receive the stove-pipe between its free arm and the wall of the opening, and the bolt connected at one end to said arm and extending through the front-plate, all arranged to co-operate substantially as described, whereby the turning of the bolt operates to clamp the pipe between the free end of the lever and the wall of the opening, as set forth.
