SPECIFICATION forming part of Letters Patent No. 742,811, dated October 27, 1903. Application filed October 25,1902. Serial No. 128.721. (No model) I times embedded in the concrete. In order to insure good work, it has been found neco essary to employ temporary or false centering, usually of wood, to support the concrete or other plastic material while it is being laid and while it is setting, the centering being erected in one portion of the building and the concrete laid and then after the concrete has set the centering being moved to another part of the building and the operation repeated. The expense of this centering is considerable, as is the expenseof erecting it and taking it down and moving it to another part of the building, and there is a considerable waste of material. Also the laying of the floors can only progress slowly, sin ce the work must proceed intermittently, unless a very large quantity of centering material is used. Instead of employing wood centering woven wire or similar material is often placed between the iloor-beams to support the concrete; but since the concrete works through the meshes of such material to a considerable extent and since the woven wire tends to bag when the concrete is rammed in laying it plaster cannot be laid directly on the under surface of the floor thus formed without great 7 5 To all whom it may concern.-

Beitknownthatwe,W1LLIAMF.W1LMo'rH, residing in the borough of Manhattan, ED- WARD 1. SMITH, residing in the borough of 5 Brooklyn, in the city and State of New York, and STANLEY GOLLIEK, residing in Jersey City, in the county of Hudson and State of New Jersey, citizens of the United States,have invented certain new and useful Improvel0 ments in Fireproofing Construction; and we do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the artto which it appertains to make and use the same.

15 Our invention relates to improvements in Fireproofing construction for the floors and ceilings of buildings and the like; and it consists in novel means for supporting a floor and ceiling from walls or floor-beams and in 20 various other features of construction, combination, and arrangement of parts, as hereinafter pointed out. p

The invention herein illustrated and described is a modification of the fireproofing 25 construction covered by the application of \V. F. lVilmoth for Letters Patent filed may 10, 1002, Serial No. 106,672. Like that construction, the one herein described and waste of material. claimed involves the use of suspension mem- The objects of our invention are 'to avoid 3o bers or suspenders secured at the ends to the use of false centering, tosupport the floor-beams or other suitable means of supconcrete or other plastic material in an import and constituting tension members, cenproved manner While it is being laid and ter pieces, supports therefor carried by said while it is setting, to insure the formation of suspenders, and concrete or other flooring laid a good under surface upon which plaster may 5 upon the center pieces; but the fireproofing be laid directly, to permit the making of the construction herein described differs from metal parts of the construction in standard that of the said former application in the form sizes and the erection thereof without fitting, and construction of the suspenders, in the bending, or other change, toprotect the form and construction of the center-piece supmetal parts from the action of fire or water,

The fireproofing constructions now comto cause the concrete to dry rapidly, and to monly used usually comprise a body of conmake the whole construction strong, simple,

4 crete or similar material, which may be apand relatively inexpensive.

plied in a plastic condition, and a series of We will now proceed to describe our inmetal supports therefor, the whole suspended vention with reference to the accompanying from floor-beams which are themselves oftendrawings, in which certain forms of fireproofnovel features in both in order ing construction embodying our invention are illustrated, and will then point out the claims.

In the drawings, Figure 1 shows a section of a floor and ceiling on a plane transverse to the floor-beams. Fig. 2 shows a section on the line X X of Fig. 1 at right angles to said figure. Fig. 3 shows a section similar to Fig. 1 of the construction employed when a flush ceiling is desired. Fig. 4 shows a sec tion of the construction of Fig. 3 on line Y Y ing a construction may be employed when an arched ceiling is desired. Fig. 6 shows a section of the construction of Fig. 5 on the line Z Z of that figure.

Referring now to the drawings and at first to Figs. 1 and 2 thereof, the said figures show floor-beams 1 1 of the usual I form. From the tops of these beams are hung suspenders 2, the ends of which are hook-shaped and hook over the tops of the floor-beams. These suspenders are formed from flat bars orstraps and are not straight throughout, but incline downwardly from their ends toward a central porzontal at the ends thereof they are vertical in the central portions 3 thereof. The central portions 3 of the suspender-rods are depressed that the concrete body or flooring may floor-beams and in order that the inclined portions beingsubstantially simple tension members. The central portions 3 of the suspenders are twisted at right angles its load without bending. Between the suspenders 3 are placed center blocks 4, which center-block supover the tops of the suspend ers 3 and spanning the space between adjacent suspenders. These yolces may be formed of wire orsmall ods bent to the proper shape and embedded in the center blocks. W'henso embedded, they may be united to the center blocks so firmly as to reinforce said blocks, forming tension members thereof,and thereby greatly increasing the strength of the center pieces. Since these center-block supblocks is laid the filling suitable timate contact therewith and also keeps the center blocks together. Because of the intimate contact of the concrete filling and the suspenders and center blocks the entire coners receive support from said suspenders only at one end, may rest at their other ends upon ledges formed in these blocks '7.

\Vhen a flush ceiling is desired and when of these suspenders are depressed to nearly the lower edge of the flange-lines of the floor-beams. The center pieces 4 are suspended from these suspenders Figs. 1 and 2. Instead of laying a continuthe center pieces, as 2, we prefer when the floorand a flush ceiling is desired The construction there- The susfloor tiles or slabs 9. by formed is verylight and strong. penders 2 form tension members of the concrete beams 8, being firmly united to said concrete by the intimate contact between the concrete and the meta The fioor-slabs 9 maybe reinforced by metal rods, expanded this construction the end center pieces may be supported from the lower flanges of the floor-beams by metal strips 10, embedded in said center pieces and adapted to rest upon the lower flanges of the floor-beams, the end center pieces themselves fitting under the floor-beams and serving to protect the same.

hen an arched ceiling is desired, the suspenders may be arched, members 11 abutting at their ends against the fioorbeams, as shown. in Figs. 5 and 6, the ing suspended from these arched'suspenders in the same manner as. in the preceding figures.

trated and described that they may be manufactured in standard sizes and lengths and the construction of or the like embedded in them. In

bent to proper form at the factory and that may be used in the desired. \Vhen erecting, it is necessary merely to spring the suspenders slightly in order to hook them over the floor-beams. The center blocks previously formed and having their supportingyokes embedded in them are then hung upon the center pieces, and the concretefilling may be applied immediately. It is therefore possible to erect the material very rapidly and with a minimum of labor. The suspenders need not be supported from the floor-beams, although this is usually most convenient. Any suitable support for the ends of the suspenders may be used.

It is obvious that our invention is susceptible to many variations and modifications without departing from the pinciples of construction herein set forth, and we do not limit ourselves to the particular details of construction and arrangement herein illustrated and described.

What we claim is 1. The combination with automatic machinery forming of these parts, if

a series of suspenders of oblong section suitably supported,

the wider faces of the'intermediate portions of said suspenders being vertical and the wider faces of the end portions of said suspenders being horizontal, of center-piece supports hun g from said suspenders, and center pieces supported thereby.

2. The combination with a series of suspenders of oblong section suitably supported, the wider faces of the intermediate portions of said suspenders being vertical and the wider faces of the end portions of said suspenders being horizontal, of center-piece supports arranged transversely between adj acent suspenders, connecting the same, and supported thereby, and center pieces carried by said supports.

3. The combination with main supportingbeams, and a series of suspenders having hook-shaped ends hooking over and supported by said beams,

the intermediate portions of said suspenders being of oblong section with the wider faces vertical, of center-piece supports hung from said suspenders, and cen ter pieces supported thereby.

at. The combination, with mainsupportingbeams, and a series of suspenders hung from the tops of said beams but depressed in their central portions below the tops of said beams, of center piece supports arranged transversely between adjacent suspenders, connecting the same, and supported thereby, and center pieces carried by said supports.

5. The combination, with main supportingbeams, and a series of suspenders hung from the tops of said beams but depressed in their central portions below the tops of said beams, of center piece supports arranged transversely between adjacent suspenders, connecting the same, and supported. thereby, center pieces carried by said supports, and concrete or other plastic material supported by said center pieces and suspenders.

6. The combination, with a series of suspenders suitably supported at the ends and depressed at and near the center, of centerpieces between said suspenders, center-piece supports connecting said center pieces to the central depressedportions of said suspenders, and means for supporting the center pieces adjacent to the inclined portions of said suspenders.

7. The combination, with a series of suspenders suitably supported, center pieces between the same, and center-piece supports connecting the center pieces to said suspenders, of beams of concrete or other plastic material parallel with and embracing sai suspenders and supported thereby and by the center pieces,the suspenders constituting tension members of said beams, and flooring supported by said beams.

S. The combination, with main supportingbeams,suspenders connected thereto and sup ported thereby and depressed at and near the center and center pieces carried thereby, the lower surfaces of said center pieces forming a substantially continuous ceiling, of beams of concrete or other plastic material carried by said center pieces and suspenders, and flooring supported by said beams.

In testimony whereof we affix our signatures in the presence of two witnesses.
