WILLIAM A. L. SCHAEFER, OF CHICAGO, ILLINOIS, ASSIGNOR T0 JOINILESS FIRE BRICK COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
Specification of Letters Patent.
Patented May 25, 1920.
Application filed April 9, 1919. Serial No. 288,744.
To all whom it may concern Be it known that I, WILLIAM A. L. Serranrnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Im rovement in Methods of Constructing ne-Piece Fire-Briok Arches, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.
My invention relates to one-piece fire brick arch and method of constructing same.
In my co-pending application, Serial Number 288,742, filed April 9, 191%), I have disclosed a one-piece, fire-brick arch, and method of constructing same, which consists in building a false work structure of metal bars or pipes supporting a metallic sheet having the arched form desired for the bot tom of the arch, and installing a mass of plastic fire-brick material on this metallic sheet. The form or false work structure disclosed in the above application is particularly adapted for witl1standinguntil the one-piece, plastic arch has been converted into fire-brir.:k-such high temperature to which such arch might be subjected before such conversion takes place.
I have found that a very slow fire is under certain conditions preferable in baking the plastic fire-brick material into a solid, onepiece, fire-brick arch. The heat required on der such conditions to convert the fire-brick material into a one-piece fire-brick arch, capable of standing up without support, is insuflicient to burn or otherwise damage Wooden forms that might be employed in this connection.
The use of wooden false work or forms being thereby greatly facilitated under cer tain conditions, it is an aim of the present invention to provide an improved method of constructing a one-piece, fire-brick, gastight arch, which consists in building a false work structure of wooden joists, supporting suitable wood centering timbers cut to the arched form desired for the bottom of the arch and stretching a plurality of slats or boards across these wood centering timbers to provide a continuous sheet having the arched form desired for the bottom of the arch, and then installing a mass of plastic fire-brick material on this continuous Sheet.
It is a further aim of the present invention to provide an improved form or false work construction of the simplest character consistent with effectiveness for centering and supporting a plastic arch until the same has been converted into fire brick, which false work is capable of quick and economical installation and is adapted to be left to burn out upon completion of the arch without involving appreciable expense.
Other aims of the present invention not hereinbefore set forth will appear from the following detailed description and the claims taken with an inspection of the accompany ing drawing which illustrates in perspective the method of anchoring a plastic wall in accordance with the teachings of my invention.
Referring to the drawing it will be seen that my improved method of supporting a plastic arch until the same has been converted into fire brick consists in the installation of suitable centering timbers l. longitudinally through the combustion chamber 4 adjacent the upper edge thereof, the upper edges of these centering timbers being cut to the arched form desired for the bottom of the plastic arch The centering timbers 1. are arranged parallel with the joists 3 which joists 3 are arranged longitudinally through the combustion chamberA, extending into the longitudinal flue passages dot the tubular boiler 6 and into the common brick rear wall 7 of the boiler setting respectively.
Joists or beams 8 similar to the joists 3 are arranged transversely across the upper edges of the joists 3 the centering timbers 1 being supported in an upright position upon these transversely extending members as shown. A plurality of slats or boards 9 are arranged transversely across the upper curved edges of the centering timbers, to provide a continuous wooden sheet having the arched form desired for the bottom of the arch. It will be apparent that any desired arched form may be readily provided by cutting the upper edges of the centering timbers 1 accordingly.
A suitable packing lO-such as for example rope asbestos-is installed adjacent the head -of the boiler 6 to insure the arch against being cracked or otherwise damaged by expansion and contraction of the boiler. The plastic fire brick material is then installed upon the arched sheet provided by the cooperating slats or boards 9, in chunks, each chunk being thoroughly pounded and worked to insure proper union with the previously installed portions of the arch. The plastic arch is built up to the form or contour of the arch desired, being run up to the asbestos packing 10 as shown.
The common brick side and rear walls of the boiler setting might be provided with a one piece fire brick lining 11 formed of the same material and continuous with the one piece arch 2 if so desired. In such event the plastic walls or linings are bonded into the common brick walls, and the corners of the lining are rounded to provide a straight jointless one piece setting for the boiler 6.
Upon completion of the plastic fire brick arch 2 the arch is dried out by means of a slow fire, sufiicient to gradually remove the moisture therefrom but insufficient to burn or otherwise damage the wooden forms or false work. i
As the plastic arch begins to set-the moisture being thoroughly removedthe heat is gradually increased to bake the plastic material into a solidone piece jointless arch, capable of standing up without support, whereupon burning out of the wooden forms is immaterial.
IVhile I have described the present invention with reference to the details of a particular embodiment it is to be understood that this embodiment is merely illustrative and it will at once be apparent to those skilled in the art that the invention may appear in other forms and be used for other purposes without departing from the spirit and scope ofmy invention.
I claim:
1. The method of constructing a one piece fire brick arch which consists in extending a plurality of joists between the head of the boiler and a wall of the boiler setting, supporting one end of said joists in the longitudinal flue passages of the boiler, anchoring the opposite ends of said joists in said boiler setting wall, arranging a second group of joists transversely across said first joists, arranging a pair of centering timbers having their upper edges shaped to the arched form desired for the bottom of the arch transversely across the upper edges of said second group of joists, arranging a plurality of slats transversely across said centering timbers to form a substantially continuous plastic fire-brick supporting sheet and then installing a mass of plastic fire-brick material upon said sheet in the form of the desired arch.
2. The method of constructing a onepiece fire brick arch which consists in arranging a plurality of joists between the head of a boiler and a wall of the boiler setting, supporting one end of said joist in the longitudinal flue passages of the boiler, anchoring the opposite ends of said joists in said boiler setting Wall, supporting a plastic fire brick supporting sheet through said anchored joists, then installing a mass of plastic fire brick material upon said sheet in the form of the desired arch and then heating said plastic fire brick material to convert the same into fire brick.
3. The method of constructing a one-piece fire brick arch which consists in arranging a pair of centering timbers having their upper edges shaped to the arched form desired for the bottom of the arch through the boiler setting, then arranging a plurality of slats across said centering timbers to form a substantially continuous plastic lire brick supporting sheet and then installing a mass of plastic fire brick material upon said sheet in the form of the desired arch.
4. The method of constructing a one-piece fire brick arch which consists in anchoring a false work structure in the boiler setting fixedly against removal therefrom said false work structure including a pair of centering timbers having a plurality of slats ar ranged there across then installing a mass of plastic fire brick material upon said slats in the form of the desired arch, then heating said plastic fire brick material to convert the same into fire brick and thereafter burning out said false work structure.
5. The method of constructing a one-piece fire brick arch which consists in anchoring a false work structure in the boiler setting fixedly against removal therefrom, then supporting a plastic fire brick supporting sheet upon said anchored false work, then installing a mass of plastic fire brick material upon said sheet, then heating said plastic fire brick material to convert the same into fire brick and thereafter burning out said false work structure.
6. The method of constructing a onc-piece fire brick arch which consists in anchoring a frame false work structure in the boiler setting fixedly against removal therefrom, then supporting a plastic fire brick supporting sheet upon said anchored false work structure, then installing a suitable packing adjacent the boiler to allow for expansion and contraction thereof and then installing a mass of plastic fire brick material upon. said plastic fire brick supporting sheet up to said packing and in the form of the desired arch.
In witness whereof, I hereunto SIIbSCllbQ my name, this 24 day of March, 1919.
WILLIAM A. L. SCIIAICFEH.
