WILLIAM G. DRAKE, OF DONORA, PENNSYLVANIA.

s rovEF'lPrin-Ameland` SPECIFICATION forming part of Letters Patent No. 745,003, dated November 24, 1903.

Applicationled November 22,1902. SerialNo.132.464. (No model.)

To cir/ZZ whom, it nca/y concern:

Be it known that l, VILLIAM G. DRAKE, a citizen of the United States, residing at Donora, in the county of lVashington and State of Pennsylvania, have invented a new and useful Stovepipe-Fastener, of which the following` is a specification.

This invention relates to devices for fastening stovepipes in the flue-openings of chimneys or other apertures through which the pipe passes, and has for its object to provide a simply-constructed and easily applied and adjusted device whereby the pipe may be securely fastened in place in position to be readily detached and adjusted to any thickness of chimney, wall, or other support; and the invention consists in certain novel features of construction, as hereinafter shown and described, and specifically pointed out in the claims.

In the drawings illustrative of the invention, in which corresponding parts in the several figures are designated by like reference characters, Figure 1 is a side elevation of the device applied. Fig. 2 is atransverse section on the line Il Il of Fig. 1. Fig. 3 is adetached perspective view, enlarged, of one of the leverclamps.

The improved device may be attached to any size of stovepipe and to stovepipes passing through partitions or walls or into chimneys or supported in any other desirable manner, and for the purpose of illustration the device is shown applied to a section of stovepipe inserted in the ordinary manner into the line-opening of a chimney, a portion of a chimney being indicated at 10 and forming a support for the pipe, a section of which is shown at 11, of the ordinary construction, the pipe being shown inserted through the usual iiueopening of the chimney.

The improved device consists in a flat relativelythin bar or plate 12, adapted to be inserted through the flue-opening between the` pipe 1l and the flue lining or thimble and with its inner end folded over, as shown at 13, to form an offset projecting laterally from the plate or bar and the extremity secured to the plate, as by a rivet 14, the offset 13 serving as a stop to prevent the withdrawal of the' plate 12 while the pipe is in position within the line-Opening.

Attached by a handle member 15 to the free end of the bar 12 is another bar 16 relatively thicker than the bar 12, but preferably of the same width and forminga continuation thereof, as shown.

Partially embracing the pipe opposite the bar 16, preferably near its outer or free end, are two lever members 17 1S, conforming to the curvature ofthe pipe and extending below its center, so that they enclasp more than one-half of the circumference of the pipe, as

indicated in Fig. 2, and forming clamp-levers adapted to be compressed into engagement with the pipe.

The adjacent ends of the clamp-levers 17 1S are inclined inwardly and outwardly away from the pipe 1l, as shown in- Fig. 2, and with apertures at the j unctures of the inclined and curved portions, the apertures adapted to receive the bent-up ends 2l 22 of the couplingrod 23, by which means the clamp-levers will be movably coupled and spaced apart with reversely-inclined adjacent portions.

The inclined portions 19 2O will be formed with recesses longitudinally of the inclined portions, as indicated in Fig. 3. The couplingrod 23 Will pass beneath the relatively thick connecting-bar 16, as indicated,and is provided with upwardly-extending spaced ears or lugs 23', forming guides between which the bar 16 slides and which prevent the lateral displacement of said bar, the bar being thus always connected with the levers 17 and 1 8 and held in position beneath a cam-lever,here inafter described.

The clamp-levers 17 1S will preferably be formed substantially in U shape in cross-section, the bottomportionsbeing curved to conform to the outlines of the stovepipe and the leg portions of the U-sections forming side walls to the levers, as indicated, by which means the levers are greatly strengthened and enabled to resist the pressure to which they will be subjected without unduly increasing the weight or bulk. I

The pipe 11 will be surrounded with the usual collar 24 at the point where it enters the flue, and connecting this collar and the leverclamps 17 1S are tie-bars 25, preferably riveted by their ends, respectively, to the collar and to the clamp-levers, as indicated at 2G 27.

One of these tie-bars will be connected to each ICO of the clamp-levers, as :indicatedlin Fig. 2 upon opposite sides of the pipe.

Fittinginto the recesses in the inclined ends 19 2O of the clamp-levers 17 18 are wedgeblocks 28 29, and between these wedge-blocks is pivotally supported at 30 a cam-lever 31, the operative end 32 of the cam-lever adapted to forcibly engage the connecting-bar 1G, which passes beneath the wedge-blocks and above the coupling-bar 23, as shown. By this arrangement it will be obvious that when the cam-lever is moved into the position indicated by dotted lines in Fig. 1 the clamplevers will be released by the depression of the wedge-blocks and the disconnection of the end 32 from the plate 16. If, however, the cam-lever be reversed in position or turned, as shown in Fig. 1 in full lines, the operative end 32 will forcibly compress the plate 16 upon the coupling-bar 23 and the pipe 11, while at the same time the wedge-blocks 28 29 will be forcibly moved away from the pipe and throw the outer ends of the inclined portions 19 2O apart and correspondingly compress the longer ends of the curved portions 17 18 forcibly against the outer surface of the pipe, and as those longer ends extend below the center of the pipe the device will be firmly clamped to the pipe, as will be obvious. By this simple means the whole device may be firmly clamped to the pipe and retain the pipe in position Arelative to the fine-opening, or other aperture through which it is passed, the offset 13 preventing longitudinal movement in one direction, and the connecting-bars 25 preventing longitudinal movement in the opposite direction, while the clamp-levers 17 18 firmly engage the whole device to the pipe.

When the device is to be applied, the collar 24, with the clamp-levers 17 18, coupled by the bar 23, and the wedge-blocks 28 29 and cam-lever 31, connected thereto by the bars 25, will be inserted over the end of the pipe which is to enter the flue or pass through the wall or partition, the connected bars 12 16 having first been placed in position upon the pipe, with the offset end 13 extending beyond the end of the pipe. The extended portion of the bar 12, with its offset end, is then passed through the flue-opening or other aperture in advance of the pipe until the offset 13 is in position upon the opposite side of the aperture, when the pipe can be readily inserted, with the portion 12, between the pipe and the interior of the opening, the relative thi nness of the portion 12 permitting this action. The collar 24 with its connected clamp-levers and attachments are then movedlongitudinally of the pipe, with the relatively thick portion 16 of the connecting-rod between the cam-lever and the pipe and preferably above the bar 23, as shown. The connected bar 12 16, which forms the connecting means between the clamp-levers 17 and 18 and the pipe-support 10, is then adjusted longitudinally of the `pipe until the offset 13 closely engages the interiorof the fiue or other aperture and the cam-lever 31 moved into operative position, as shown in Fig. 1, which action rmly locks the parts together, as before described. By this simple arrangement the pipe may be very quickly and readily locked in position and firmly supported relative to the fiue or other Vopening and all danger of the displacement of the pipe averted. y

The parts are all simple in construction and can be manufactured very cheaply and readily applied by persons without previous skill and will be found very convenient and useful for the purposes described.

The parts may be modified in minor particulars without departing from the principle of the invention or sacrificing any of its advantages.

The clamp-levers 17 18 will preferably be of sheet metal pressed or stamped into shape, but may be constructed of other metal, if preferred.
