Application January 11, 1954, Serial No. 403,156

3 Claims. (CI. 7295) This invention relates to certain new and useful improvements in constructional means for supporting chimneys and the like, particularly in buildings such as dwellings in which a full chimney extending to ground level is unnecessary, but a superposed chimney section adjacent the roof or an upper level of the building is desirable, both for utilitarian and ornamental purposes.

Many municipla building codes require the inclusion of chimney-like structures, particularly for the reception of the discharge ends of vent pipes from household devices such as plumbing, space heating means, and other instrumentalities. It has heretofore been necessary in order to provide such a chimney-like structure to erect the chimney full size and full dimension from the lower level of the building, resulting in a relatively expensive structure and one which occupies a substantial portion of the room space in which the unit is mounted. While such full chimneys are at times desirable in those buildings in which there is ample space and in which the lower level portion of the chimneys is desired for the useful purpose of accommodating a fireplace or other opening, in many smaller constructions space for such purposes is not available and it is substantially imperative that the chimney-like superstructure be provided without interrupting the wall space of the lower level room areas.

A principal object of the present invention is to provide supporting means adapted to receive and support a chimney-like superstructure, which supporting means are adapted for mounting in the confines of an interior wall as of a building without interrupting the wall space.

A further object of the invention is to provide such support means which may be mounted in and engaged to elements of the wall construction during the construction thereof, and which will be concealed in the wall upon the finishing thereof.

Y A further object of the invention is to provide in such support means post-like means, a chimney supporting platform mounted rigidly on the post-like means, and means for attaching the support means within a wall structure.

A further object of the invention is to provide in such support means attachment means which is shiftable relative to the post means and includes a flange for overlying and being attached to a header forming part of the wall construction.

A further object of the invention is to provide such attachment means which additionally includes depending flanges means, the depending flange means being positioned alongside the header of the wall construction.

A further object of the invention is to provide attachment means for a chimney support, which attachment means include a collar slidably engaged with post means of such support; and

A further object of the invention is to generally improve the design, construction and efliciency of support means as for chimneys.

The means by which the foregoing and other objects of the present invention are accomplished and the manner of their accomplishment will be readily understood from the following specification upon reference to the accompanying drawings, in which:

Fig. 1 is a perspective view of the preferred form of support means of the present invention.

Fig. 2 is a front elevational view, partially fragmentary, illustrating the support means in position relative to the building construction.

Fig. 3 is a fragmentary side elevational view of the upper end of the preferred form of support means with parts broken away for purposes of illustration.

Fig. 4 is a fragmentary side elevational view illustrating a variation in the attachment means of the invention; and

Fig. 5 is a view similar to Fig. 4 of a further variation in the attachment means of the invention.

Referring now to the drawings in which the various parts are indicated by numerals, the preferred embodiment of the support means comprises an elongated vertically disposed post 11 which is preferably cylindrical and may be a hollow pipe member if desired. To the lower end of post 11 a shoe 13 is rigidly fixed, the shoe 13 being provided for seating upon and being attached to a lower level surface of a building construction such as a concrete floor slab 15. To the upper end of post 11 a chimney carrying platform 17 is rigidly fixed. Platform 17 preferably consists of a peripheral frame 19 formed of angle iron integrally connected as by welding, although in some circumstances the frame may be formed by appropriately cutting and bending angle iron material into the desired shape. Peripheral frame 19 is disposed with one leg of each angle horizontal and with the other legs of the angles projecting upwardly from the outer edges of the horizontal legs, thus forming a peripheral flanged frame for platform 17. Seated on and integrally secured to the horizontal flanges of frame 19 is a flat imperforate sheet 21, sheet 21 being so connected to frame 19 as to create a water-tight platform. Preferably sheet 21 intermediate its edges is strenghtened by straps 23, and post 11 abuts and is preferably welded to the underside of sheet 21 and straps 23 substantially at the midpoint thereof. Preferably the platform is additionally braced by diagonal struts 25 extending from the respective corners of platform 17 downwardly and inwardly to post 11, struts 25 being rigidly fixed at their upper and outer ends to platform 17, and likewise rigidly fixed at their inner and lower ends to post 11.

Intermediate the length of post 11 an attachment means 2 7 is mounted. Preferably attachment means 27 includes a substantially cylindrical hollow collar 29 slidably and rotatably engaged upon post 11 so that attachment means 37 may be shifted along the length of post 11. Integrally secured to and shiftable with collar 29 is a horizontally disposed rectangular plate 31 which extends outwardly from the upper extremities of collar 29, and is of a length substantially in excess of its width. The plate 31 is preferably provided with suitable apertures 33 for receiving bolts 35 in order to attach the device in position. In the variation illustrated in Fig. 4, attachment means 27 is additionally provided with a depending vertically disposed flange 131 which is integrally connected to and depends from one of the longer edges of horizontal plate 31 and is spaced a minor distance from the exterior of collar 29, and in the variation shown in Fig. 5 attachment means 27 is provided with a second vertical flange 231, which similar to vertical flange 131 is integrally connected to and depends from the edge of plate 31 opposite to vertical flange 131 and is similarly but oppositely spaced from collar 29.

In the use of the device it is erected during preliminary stages of the building construction. Thus after the headers 37 and studs 39 have been erected the headers are =notched out as at 41, notch 41 being of size to freely, but snugly, receive collar 29. Shoe 13 may be seated on floor slab 15 and secured thereto, preferably the wall framing being cut out as at 43 to accommodate the shoe. Post 11, platform 17 and attachment means 27 are then disposed vertically, and collar 29 is positioned in notch 41. Attachment means 27 maythenbe rotated, if .necessary, until the elongated plate 31 is substantially alined with the upper edges of headers Z77. Bolts 35 may then be engaged into the headers, thus securing the attachment means in position, and. the attachment means, as is be lieved plain, retains the support unit in upright position. The platform is thus supported above the level of the top of the wall and the outwardly flanged peripheral frame 19, and sheet 21 are positioned to receive chimney structure 45. The flanged frame 19 serves as an accurate form for the chimney erection, and being imperforate and water-tight the platform 17 supports the chimney 45 without danger of leakage from rain or the like flowing downwardly along the chimney.

It will be seen that in the event the house construction settles or changes position the attachment of attachment means 27 to theheaders will not be affected thereby as the sliding engagement between collar 29 and post 11 will permit shift of the posts along the collar without interrupting the attachment.

it will be seen that post 11 and collar 29 are of diameters to fit within the confines of the wall framing, and when the wall is completed by the application of laths and plaster, or by the application of composite boarding, a flat and uninterrupted surface will be presented.

In the use of the device, varied as shown in Fig. 4,

the vertical flange 131 seats against a vertical face of header 37 and may be attached thereto by suitable bolts or otherwise as desired, thus contributing materially to the stability of the attachment. Similarly, in the variation shown in Fig. 5, the flanges 131, 231 will respectively embrace the opposite side faces of headers 37, the sliding engagement of collar 29 with post 11 permitting the raising of attachment means '27 above the level of headers 37 to clear flanges '131, 231, and that attachment means 27 may then be moved vertically into position with flanges 131, 231 embracing the sides of the headers and attachment plate 31 seating on the upper edge of the headers.
