To all," '2v/'tom t muy concern:
Be it known that I, CHARLES W. DON- ALDsoN, a citizen of the United States,1'e siding at Akron, in the county of Summit and State of Ohio, lhave invented certain new and useful Improvements in Systems of Fireproof Building Construction of which the following is a specification,
The improvements of this invention havev to do with fireproof building construction and embody a system of such construction wherein I employ a novel method and structures whereby to erect buildings which are not only reproof but comprise double walls where necessary or desirable, allowing a .free circulation of air at the inside and outside faces ot .main walls, with the customary advantages of damp-proofness, coolness in the summer, and warmth in the winter.
The method of construction which I pursuein carrying out mysystem includes as one of the most essential phases of my invention a mode of erecting main and partition walls, beams, floors and roofs of reinforced concrete, the customary use of wood forms being entirely dispensed with. The
may be said to comprise elements of such structures themselves forthe reason that I utilize metall lath which enters into the wall or other unit of construction as a reinforcing element, as the form or a side of the form by'which the particular unit is constructed. In carrying out my method, for instance, as applied to a wall construction, a metal lath form is made by erecting the lath so as to providespaced sides similar to the sides of a form, these sides being rendered substantially imperforate by applying thereto a cement mortar, permitting said mortar to reach the final stages of setting, and
. thereafter filling in to the space between the form sides thus provided 'the concrete,
where a solid wall, beam, rafter, or similar unit is tofbe made.
In addition to the foregoing method, my invention comprehends special constructions of solid, and hollow walls, beams both outsideu and inside, columns, and ceiling and corner constructions as will be hereinafter fully presented.
In the accompanying drawings:

eferring particularly to the main wall construction illustrated in Figs. Q and 3, it will be observed that the wall is made up of aninside section 1 and an outside section 2. The outside section is first erected and partly in sec-v 4consists of extra heavy metal lath on which are hung by means of wire, ete.A the beam hangers 3 and to which are fastened the base forms 4. The outside section 2 is then supplied with a coat of cementmortar on both sides of the metal lath designated 2a, the mortar being shown at 5. A three by four, 0r other suitable sized,sill 6 is then placedin the base form and forms a nailing ground for a base board and also for the inside metal lath 2D of the inside section l of the wall. The mortar 5 on the outside wall sec` tion 2 is permitted te set before the inside work is started. Struts in the form or" blocks 7 are placed between `the wire ties fastened to the outside wall and form spacers between the inside and outside sections as' seen best in Fig. 2. Verticalbattens 8 may now be placed in position and are held in place by the wire ties 9, intermediate the blocks 7 by drawing said ties taut. The metal lath 2b vof the inside section 1 of this wall is now securely fastened to the battens 8 and is coated with a rich mortar of cement applied to its outer surface. In this manner I provide a most excellent main hollow wall construction, the advantages of which will be obvious to those versed in the art..
. Fig. 4 illustrates an inside or partition wall. In this instance, form the wall by using the heavy metal lath 10 plastered with the richcement mortar preferably, on'both sides. At its lower end the lath is clamped between two wood strips 11 which provide the necessary nailing ground for base boards. At its Vupper end the lath is run up etween the curved ends of the floor beam lath, and firmly tied thereto by suitable metal ties. Previous to the pouring of the concrete for the fi'oor slabs and Hoor beams the base strips 11 and the head portions of the lath are properly set in place. Furthermore, where openings such as those for windows and doors are provided in the partition, wood strips will be framed about such openings.
Fig. 5 of the drawings,`and also Fig. 2 in less detail, illustrate the construction of the main beams which will now be set forth. The main beam is formed around the outside wall of the building and it is contemplated to use the reinforcing structure therefor as the form in or on which the concrete for the beam is poured, the reinforcing beam becoming embedded in said concrete on one side and being covered with cement structure on its opposite side, the latter being applied first in order to establish the desired imperforateness of the reinforcement necessary as previously suggested to 4enable the reinforcingr means to most effectively perform the desired function of a form member,
Referring to Fig. 5 it will be seen that on the outside wall section are mounted special hangers 12 consisting of lower angular portions 12 and upper curved extensions 12". The angular portions directly engage or overlap the inside section 1 of the wall as shown at 12, and said angular' portions arel of somewhat U-form, thereby constituting spacing members between the sections 1 and 2 aswell as beam forms.
special hangers 12, and designated 13, are placed between the hangers 12, which are spaced apart a suitable distance, said lath forms 13 together with the hangers constituting a Y continuous form for the beam.
It will be observed on reference to Figs. 2 and 5 that the floor lath 14 at its curved end rests on and is suitably connected by ties with the hangers 12 and lath forms 13, and therefore constitutes the member of scribed are firmly connected by wire ties, reinforcing rods such as shown at 15 and 16 are placed in position in the space in which the beam will ultimately be molded; thereafter the under side or outside face of the beam foi. i and floor lath are covered with the coat of cement mortar such as hereinbefore referred to, and after said mortar has A Metal lath forms somewhat similar in shape to the contemplate providing inside reinforcing. the beam. The parts 3ust debeen allowed to set to its nal stages the concrete for the beam and also for the floor slabs is poured.
Where the beam runs over' door openings, wooden strips are placed between the hangers 12 as shown in Fig. 5 at 17, in substitution for the metal lath forms 13, and provide nailing strips for head casings and heads of window forms.
The fioor construction employed by me has been partially described above, but especial note is made of the manner in which the fioor lath 14 is reinforced by crimping or clenchingportions thereof around reinforcing rods o'r bars 18, which extend across 80 the lath beneath the same. .Wood strips are embedded in the surface ofl the concrete poured for the floor slabs, as shown at 19, Figs. 2, 5 and 7, and form nailing bases for thefinished fiooring boards.
v The inside beam construction used by me .is shown best in Fig; 4 and the structure is made up of the. downwardly curved ends of the metal lath 14 forming the ceiling or floor reinforcement. The lath of course acts not only as an eXtra reinforcement but offers a base for the plastered ceiling shown at 20. When'the lath sections are properly secured together as shown in Fig. 4, at opposite sides of the heavy metal lath 10 of the inside par- 95 tition wall, the under sides of the lath sections 20 are plastered with mortar and'when this plaster has nearly set the concrete for thc inside beams and floors is poured after the .manner hereinbefore suggested,l
The columns used by me are constructed as shown in Figs. 8 and 9, the outside faces of the columns forming the curved corners of the rooms inside of the structure. In other words, the heavy metal lath 10 of the 105 inside or partition walls is connected at opposite sides with the curved lath sections' 21, the latter in turn connecting with other of the partition walls in an evident manner when Fig. 8 is referred to, and these lath 110 sections 21 lwith a coating of cement mortar applied thereto constitute very` adequate forms'when said mortar has set. The concrete for the column is poured into these forms and thus the column and the curved 115 corner walls, so to speak, of the rooms of the building are simultaneously made.' I suitable vertical reinforcing rods properly tied together, for the inside columns designated 22 as a whole, 120 said reinforcing elements being denoted 23.
In Fig. 9 a corner column detail is illustrated, these columns being outside columns1 forming virtually a part of the main or outer wall construction of Here the inside wall section 1 and the outside wall section 2 form in connection with special narrow lath sections 24, the form in which the concrete is poured to make the column, the lath 2" of the inside wall sections 134 window or 1,293,377 l being Joined together on a curved line so secured to the base portion of said lath secthat t e inside of the column is curved and tion, beam hangers secured to the upper p0rmakes the desired curved vcorner for the the manner in which the ceiling curves to meet the Walls, as more sanitary than the customary-shaped corner constructions on account of lesser possibilities of collectionl by the dotted rendered solid, the concrete being poured the Wall sections 1, l suc space up to a point approximately at the ground level.
