STOVEPIPE -FASTENER.

Application filed July 31, 1913. Serial No. 782,220.

To (ZZZ whom it may concern:

Be it known that I, LINCOLN A. Lown, a citizen of the United States, residing at Watson, in the county of Atchison and State of Missouri, have invented a new and useful Stovepipe-Fastener, of which the following is a specification.

This invention relates to improvements in stove pipe fasteners and has for its object to provide a device of this class in which the pipe collar forms a part of the device.

A further object is to provide adjustable means whereby the distance the stove pipe projects into the chimney wall can be easily and readily adjusted.

A further object is to provide a stove pipe fastener with a collar connected thereto so that it will be practically impossible for the collar to become separated from the chimney wall which would allow the sparks to pass therethrough, and furthermore to provide the collar with a plurality of apertures for the cooling of the collar and stove pipe adjacent the portion of the stovepipe which is inserted within the chimney wall.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed without de parting from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1 is a view in longitudinal section of my improved device, showing the same secured to a stove pipe of which portions are broken away and in position within a chimney wall. Fig. 2 is a plan view of the attaching member illustrated in Fig. 1. Fig. 3 is a view in longitudinal section of a somewhat modified form of the device. Fig. 4; is a front view in elevation of the collar and sliding stop. Fig. 5 is a plan view of the fastening member as illustrated in elevation Specification of Letters Patent.

in Fig. 3'. Fig. 6 is a cross sectional view taken on the line 66 of Fig. 2.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 6 is a chimney wall in section and provided with the aperture 7 which provides for the insertion of a stove pipe.

The fastener as illustrated in plan in Fig. 2 comprises a body portion 8 in the form of an elongated strip preferably formed of metal and rivetedly connected to which is the two piece head 9. A two-piece head 9 eX- tends at right angles to the body portion or shank 8 and constitutes an anchor for the fastening device by contacting with the inner surface of the chimney wall. The two pieces of the head being rivetedly secured to the shank, allows for the rotation thereof about the same as a center, it being noted that the friction holding the same against rotation is suflicient to prevent any accidental movement thereof. The two pieces of the head are provided with the upstanding flanges 1O struck upwardly therefrom and which constitute a stop to prevent the excessive insertion ofthe stove pipe 11 within the chimney flue which would tend to cut off the draft thereof with obvious disadvantages. Attention is called to the fact that the two parts of the head overlap and are connected by a rivet to the shank 8 as clearly illustrated in Fig. 6 of the drawing.

The outer extremity of the shank 8 is provided with the curled end 12 connected to which is the tension spring 13, the latter being by some means connected to the elbow 1% of the stove pipe. The last mentioned means in the present illustration being in the nature of a wire 15 wrapped around the said elbow and bent upon itself as will be apparent from a reference to Fig. 1. Thus a suitable tension will be exerted upon the shank 8 which will result in the stove pipe 11 being forced and held rigidly within the chimney aperture 7. p

The shank 8 as clearly depicted in Fig. 2 is provided with the longitudinal slot 16 for the reception of a securing, bolt 17 the latter being secured to a sliding stop 18.

Q 1,11ae1a T he sliding stop 18 comprises a plate with the overhanging ears 19 which embrace the sides of the shank 8 and are guided for relative motion thereby. The securing bolt 17 is provided with a suitable nut 20 thereon which is adapted to draw the sliding stop into frictional engagement with the shank 8 to lock the stop in adjusted position on the shank. A collar 21 is secured to the sliding stop by means of a suitable rivet 22, the stop in this instance being provided wit-l1 a downwardly extending flange 23 in order to effect such connection. The collar 21 is of the usual annular construction, and fits over the stove pipe 11. A number of aper tures 24. are provided in the said collar for the cooling of the collar and the adjacent portions of the stove pipe, the collar acting in the nature of a radiatingflange as it is thought will be readily apparent. It has been found in practice that unless the collar is rigidly secured to the stop, there is extreme danger of the collar drawing away from the chimney wall with the result that sparks are liable to work their way through the aperture 7 and to fall upon the carpet or floor with the resulting damages by fire, etc. In this connection it might be pointed out that the present application is a decided in'iprovement in this respect over my previous Patent #827,876.

It has been found advisable in some instances to provide means whereby the length of pipe inserted within the chimney wall may be varied, this being especially true when the chimney wall is of considerable thickness and there is no necessity of the pipe extending entirely therethrough. Other advantages might be mentioned but however, it is thought that they are readily apparent and in order to efiect this adjustability of the length of pipe inserted a second longitudinal slot 25 is provided in the shank 8 as illustrated in Fig. 5 and slidably disposed therein is the bolt 26, forming an abutment against which the stove pipe 11 may contact. An adjusted position cf the bolt is illustrated in Fig. 3 and shows the stove pipe 11 held at some little distance from the inner surface of the chimney wall. Also in the modified form as illus trated in this figure the collar 21 is formed integral with the stop 18, the peculiar advantage of the latter construction being that there will be no danger of the collar and sliding stop becoming separated due to a failing the rivet 22 or is there any likelihood of the two parts experiencing a pivotal action. about the rivet 22 when the stove pipe has been removed from the collar. lso the construction is somewhat simpler and presents a more neat appearance "By forming the head in two parts, it allows the head to be collapsed for the in sertion thereof in a chimney wall opening of limited or restricted diameter. The parts of the head are again brought into their normal and extended position after having negotiated the said opening.

Having thus fully described my invention, what I claim to be new and original with me is 1. In a device of the class described, the combination of a fastener including a shank and an outstanding head, said shank provided with a longitudinal slot, a. sliding stop mounted for sliding movement upon said shank, securing means extending through said slot and said sliding stop to lock the stop in adjusted position on the shank, a collar connected to said stop, and means for securing a stove pipe to said shank.

2. The combination with an apertured chimney wall and a stove pipe of a fastener including an elongated shank provided with a longitudinal slot, and a head outstanding therefrom and contacting with the inner surface of the chimney wall, a tension spring, the remote extremity of said shank being connected to said tension spring, the latter in turn connected to the stove pipe, the said fastener head provided with an upstanding stop limiting the movement of the stove pipe, and a sliding stop provided with overhanging ears embracing the shank sides, securing means extending through the said stop and through the shank slot to lock the stop in adjusted position on the shank, and collar connected to the said stop and con-- tacting with the external chimney surface.

3. In a device of the class described, the combination with an apertured chimney wall and a stove pipe fitting therein, of a fastener including an elongated shank provided with longitudinal slot therein, a head connected to the said shank and outstanding therefrom engaging the inner chimney wall surface, a bolt rigidly secured to the shank adjacent the head thereof and forming an adjustable abutment for the said stove pipe to regulate the length of pipe inserted within the said chimney aperture, an apertured collar fitting over the said stove pipe and contacting with the external chimney surface, a sliding stop projecting from said collar and comprising a plate with overhanging ears, the said overhanging ears overlapping the side edges of the said shank, and a bolt extending through the said sliding stop, and through the shank slot and adapted to lock the stop against sliding motion with respect to the shank, and resilient means secured to the remote end of said shank and engaging the stove pipe for holding the same in rigid position within the said chimney aperture.

4. A stove pipe fastener comprising a shank and an outstanding head, means for securing said shank to a stove pipe, a stop mounted for sliding movement upon said shank, means engaging the said shank and In testimony that I claim the foregoing sliding stop and adapted to lock the stop as my own, I have hereto affixed my signain adjusted position on the shank, and a ture in the presence of two Witnesses.
