WITNESSES ATTORNEY STEVENSON E. BARR, OF TACOMA, WASHINGTON.

COMBINED THIMBLE ANT) STOVEPIPE I-IOLDEIELv Application filed'August 15, 1921.

T 0 all whom it may concer /r.

Be it known that I, STEVENSON E. BARR, a citizen of the United States, Tacoma, in the county of Pierce and State of ashington, have invented new and useful Improvements in Combined Thimbles and Stovepipe Holders, of which thefol lowing is a specification.

This invention'relates to stove pipes, comprehending p1pe 1n engagement'with a'fluethimble.

The primary object of the invention residesv in the production of ,a novel type of clamping device which issimple in construction, eflicient in use and may be manufactured and sold at comparatively a low cost, and one which holds the pipe against accidental displacement from the flue thimble previous to accomplishing the final clamping action of the pipe to such thimble.

To this end, I contemplate, among other features, constructing a clamp carried by the flue thimble and arranged in adjacent relation to and in advance of the mouth of the flue thimble, whereby after the thimble is positioned within the flue the clamp is so disposed to permit the attachment of the pipe in the flue thimble in a convenient and expeditious manner.

l/Vith the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawing and pointed out in the appended claim.

Figure l is a side elevation showing a clamping device provided with the stove pipe thimble, portions being broken away.

Figure 2 is an end view thereof.

Figure 3 is a detail view of the clamping device.

Referring more particularly to the accompanying drawing, in which like characters of reference refer to corresponding parts in the several views, 5 denotes a flue thimble constructed of well known material such as sheet metal or the like and adapted to be inserted within the flue opening A.

Secured exteriorly of and in embracing relation with the mouth portion 6 of the flue thimble, and at diametrically opposite points is a plurality of flexible strips 7. These strips in conjunction with the band 8 constitute my improved clamping device for Specification of Letters Patent.

residing at particularly a' clamping device therefor and-sodesigned to fasten the stove Patented July 4, 1922. Serial No. 492,572:

securing the pipe section 9.within the mouth 6 of the flue thimble. These strips 7 are fixedly secured to the flue thimbleat opposite diametric points through the employment of'lugs 9, the protruding extremities of these lugs penetratingthewall of'the flue opening, thus securely'fastening the strips withinthe opening; of the flue and positioning theof the thimble; saidf' strips being material; the; projecting extremities 10 of said strips providea resili'ent'clamp for re tainingthe pipe section 9 againstanyaccidental displacement from the flue thimble, previous to clampin the ring 8 around the said pipe section.- 11 order to accomplish this function, the protruding extremities 10 of the strips are offset inwardly as at 11, disposing the projecting extremities inwardly of the inner circumference of the mouth of the thimble in adjacent relation thereto and forwardly of the same. The strip secured to the upper portion of the flue thimble denoted by the character 12 has fixedly secured to the free extremity of the projecting portion 10 thereof through the employment of a suitable fastener 13, the clamping band 8, thus preventing any accidental rotation of the band during the insertion of the pipe section 9 within the mouth of the flue thimble, and further retaining the band in embracing relation with the portions 10 of the strips at all times, hence it is obvious that the expansion of the resilient strips 7, due to the initial engagement of the pipe section 9 with the flue thimble, causes the expansion of the projecting extremities 10, and the expansion of the portions 10 of the strips are limited by the contact of the same with the inner circumference of the clamping ring 8. The projecting extremities 10 of the strips are terminally bent to provide outwardly extending projections 14 serving to prevent any longitudinal movement of the clamping band, consequently holding the band in embracing relation with the extremities at all times.

The clamping band above referred to and denoted by the character 8 is in the form of a split band, the free terminals of which are bent downwardly to provide depending lips 15 and 16 through which a suitable fastening device in the form of a screw 17 is free extremities lO'of the strips at aip'oint forwardlyof themouth' As previously stated, the constructed of resilient device 17 is thence screwed ther serves to prevent any rotary movement of the nut upon the shank of the fastening device 17 thus positively holding the nut to said fastening device at all times.

From the foregoing description, taken in connection with theac'companying drawing, the advantages of construction and the method of operation will be readily apparent tolthose skilled in the art to which the invention relates, and while I have described the principles of operation of the invention, together with the device which I now conthe lip 16 upon itself, andv sider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the appended claim.

What is claimed as new, is

A device of the class described compris ing a flue thimble, a plurality of strips secured exteriorly of said thimble, a split clamping band secured to one of said strips and disposed in embracing relation to the other of said strips, said band being terminally provided with a pair of depending lips, one of which has a U-shaped slot opening out the rear edge of the lip, the other of said lips being bent upon itself to provide a space, a nut located in said space, and a fastening device seated within the slot of the first mentioned lip and passing through the nut and the opposite lip, substantially as and for the purpose specified.

In testimony whereof I aflix my signature.

s'rnvnnsoiv E. BARR.
