STOVEPIPE. SUPPORT.

Application filed December 8,. 1925.

The general object of the invention is to provide a device adapted for supporting the angularly disposed runs of a stove pipe against accidental displacement from one another, and also for supporting the said runs in the required alinement with the chimney opening and the stove.

The invention further proposes to provide a device adapted for supporting a relatively long run of stove pipe against sagging.

The invention still further proposes to provide a device which is readily adjustable to engage and effectively support stove pipes of various sizes.

The invention still further proposes to provide an adjustable stove pipe holder adapted to readily accommodate the vertical and horizontal runs of a stove pipe regardless of the intervening distances between these runs and the adjacent side wall and ceiling of a room.

The above and other objects are accomplished by instrumentalities pointed out in the following specification.

The invention is clearly defined in the claim.

A satisfactory embodiment of the invention is illustrated in the accompanying drawings forming part of the specification,

and in which Figure 1 is a side elevation of one form of my device in use.

Figure 2 is a side elevation of the form of the device shown in Figure 1, but on an enlarged scale, with parts of the device broken away to show the construction and relation of the other parts and further Showing the device connected to the hori- 4 zontal and vertical runs of a stove pipe.

Figure 4 is a view similar to Figure 2, but showing a modified form of my device in use.

Figure 5 is an inverted plan view of Figure 4, showing a portion of one of the arms in section and disclosing the pivotal connection between the arms, and

Figure 6 is a contracted side elevation of a further modified form of the device.

The form of the device shown in Figures and. 2 comprises hollew metal base 5; nine Serial No. 74,116.

end of which is provided with a flange 6 that is adapted to bear upon a'portion of the wall 7 of a room immediately behind the vertical runs 8 of the stove pipe, and below the horizontal run 9 of the said pipe. The base is oblong and is horizontally disposed and fixedly secured to the wall 7 in any preferred manner as by screws or their equivalents 10. The base provides 'a support for an extensible arm a made up of telescoping sections 11,. 12 and. 13 which are preferably formed of metal tubing, the inner section 11. being fixedly secured to the outer end of the base 5. Set screws l l and 15 are em. ployed for securing the

sections

12 and 13 in any of their adjusted positions. An arm 16 is pivotally connected as at 17 to the intermediate portion of section 13 located beyond section 12. For convenience in manufacture, the arm 16 may be formed of a single strip of metal bent into a U-shape, as indicated. by 18 in Figure 5, so as to straddle sec tion 13, the terminals of the sides having openingsfor the reception of the pivot pin 1.7 which passes through the section 13 and strip 18. A stop 19 in the form of a cross piece connecting the free end portions of the U-shaped strip 18 is rovided for abutting the section 13 when the arm 16 is thrown outwardly and at right angles to the section 13, as clearly shown in Figures 1, 2, 4 and 5. Thus the stop operates to limit movement of the arm 16 in one direction. The outer end of section 13 is provided with. a cross piece that may be formed of a single length of wire which is clearly shown in Figure 5 and indicated by 20. One end of the length 19 is bent so as to provide a V-shaped socket 21 clearly shown in Figure 3, and the opposite end is bent so as to provide an eye 22 to which is connected one end of an extensible element herein shown as a closely wound coil spring 23.

The extensible element 23 is adapted to provide a loop when its free end portion is inserted into the V-shaped socket 21. In this connection it will be observed by refer ence to Figure 3 that the socket 21 and spring 23 are proportioned so that the inner portion of the sides of the socket 21 dispose themselves between adjacent coils of spring 23 when the latter is forced into the socket. This has the effect of interlocking the free end portion of the spring with the side walls of socket 21 and prevr' 1 endwise movement the free end p0. the spring from,

the socket. The cross piece construction, indicated by 21 and as just described in connection with section 13 of arm a, is employed in connection with the outer end of arm 16, as indicated by 24: in Figure 2. The cross piece construction of arms 16 carries a second extensible element in the form of a coil spring 25. In the use of the device thus far described, the base. 5 is secured in alinement with the vertical run 8 of the stove pipe, as shown in Figure 1,'

after which the sections of arm a are adjustably secured so that the outer end of section 13 is adjacent to the vertical run 8 of the pipe. The spring 28 is then extended around the run 8, and'its free enl portion inserted into socket 21, as shown in Figure 3. The arm 16 is then turned upwardly and at right angles to section 13 and spring adjusted around the horizontal run 9 and engaged by the cross piece 24, as shown in Figure 3; l-Vhen the parts are so positioned, the outer ends of

arms

13 and 16 will contact respectively with the surfaces of the runs 8 and 9. Prior to engaging the free ends of the springs 21 and 25 ot' the sockets 21, the said springs are tensioned to any required extent so as to perceptibly bind upon the runs 8 and 9 of the stove pipe and when the springs are tensioned to the required degree, the free end portions of the said springs are introduced into the sockets without permitting the tensioned portions of the springs to relax. In this way and when the free end portions of the springs are engaged by the sockets 21, the runs 8 and 9 are tightly gripped by the springs so thataccidental displacement of the'joints of the runs 8 and 9, or disengagement of these from the elbow 26 due to vibration, is prevented. It will, therefore, be observed that when the device of Figures 1 and 2 is in use, the weight of the horizontal run 9 is thrown upon arm 16 and not upon elbow 26. Therefore, sagging ot the horizontal run 9 be tween the wall 7 and the elbow 26 is prevented.

With the form of the device shown in Figures 4 and 5, the base support shown in Figures 1 and 2 is eliminated, and the arms 27 and 28 are connected to the runs 29 and 30 of the pipe beyond the elbow 31. Inthis connection it will be noted that the extensible features of arm a in Figures 1 and 2 are eliminated from the arm 27 in Figure 4, and that the arms 27 and 28 are arranged at right angles so as to bear on angularly disposed portions of the runs 29 and 30.

Springs 32 and 83 at the ends of the arms 27 and 28 are identical with the springs 23 and 25, and the arms 27 and 28 are pro Vided with cross pieces 20 for carrying and engaging the said springs in the manner described in connection with Figures 1 and 2. This construction is ideal for holding the vertical and horizontal runs of a stove pipe against displacen'i-ent from the opposite ends of an elbow in instances where the elbow is located at a relatively removed distance from a wall.

The form shown in Figure 6 is adapted for supporting a relatively long horizontal run of stove pipe against sagging. In this connection the arm 0 is extensible in that the said arm consists of

telescoping sections

34, 35 and 36, the inner ot' wnich is secured to a base 37 which is adapted to be secured to a ceiling 38 and to depend therefrom. This construction permits the arm 0 to he extended to a point adjacent to the pipe, and the outer end of the outer section 34.- is provided with a cross arm 39 to one end of which is connected a spring 10, the free end of which is adapted to be engaged by a V- shaped socket 11 in the opposite end of the cross arm. The spring and cross arm 39, together with the socket 11 are identical with the structures described in connection with Figures 1 to 5 inclusive. hen the device is arranged as shown in Figure 6, spring 410 is tensioned around a horizontal run 411 off the pipe and when the "free end of the sprin is arranged within the socket 4-1, the pipe is supported by the device which depends from the ceiling.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes; and I reserve the right to employ such as may come within the scope of the appended claim.

I claim:

A stove pipe support comprising a pair of angularly disposed arms connected together at one end, cross bars secured to the free ends of said arms and provided at one end with sockets and tensionable ele ments adapted to be extended around the vertical and horizontal runs of a store pipe lVILLIAM L.
