"Patented July 14, 1908.
Application filed February 19, 1908. Serial No. 416,735.
To all whom it may. concern:
Be it known that I, WILLIAM S. KING, -citi-' zen of United States, residing in the city and county of San Francisco and State provements in Centering f'o Concrete and Tile Construction, of which the following is a specification. I
Myinvention relates to improvements in concrete, tile and like construction. It consists in the construction and employment of temporary, adjustable and removable centering pieces, upon and about which the super-structure may be laid, said centering pieces being removable and adapted to be continually used in new work. i
It also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a section showing the device applied. Fig. 2 is a plan view of a pair of p ates. Fig. 3 is an end. view of one of the plates showing the supporting piece 4.
In the laying of concrete floors which are supported by I-beams,.and for similar construction, it is customary to make a centering of wood or thelikeupon which the coricrete, atiling, or equivalent lling is supported until it has properly set and hardened,
after which the centering structure is removed, being usually destroyed in its removal..
It is the object of my invention to-provide a metallic center which may be adjustably fixed in place, and is readily removed'after it is no longer needed.
In the present drawings have shown I- beams A,such asare'commonly employed for floor and like structures.
2 are metal strips of any suitable or desired width and thickness having the ends adapted to lie flatwise against the beams, and being bent at theiriipper angles so that they stand edgewise across the space between the beams, as shown at 2". The fiat portions 2 of these plates are perforated with holes, as at 3, and strips of metal 4 are formed, preferably with a plurality of holes, so that they;
maybe bolted orotherwise secured through the holes 2. The free ends of these strips 4 are bent outwardly from the plates 2 so that they will rest upon the lower flanges of the beams A as plainly shown in Fig. 1. By means of the holes 3, these supporting pieces 4 may be raised or depressed to suit the of Californla, have invented new d useful 'Im' depth of the beams A, and the desired depth and character of the structure to be supported above the center 'andbetween the floor beams. As thesebeams may be set at various distances apart, I have shown them slotted as" at 5, the slots registering with each other, and by means of bolts 6 they may be secured together bypassing the bolts through the slots and tightening them up by nuts or otherwise; 7
It will be understood that separate. holes may besubstituted for the slots, but the latter are more convenient for close adjustment, and when thus ent sides 2 will lie substantially close to the roperly adjusted, the diverower flanges of the beams A, and the plates 4 will support the structure at any desired distance below the level of the tops of the beams A. Wood be used at 2.
The plates 2 extend below-the bottom of or other material may also the beams, converging toward each other as shown, and they are perforatedwith holesadapted to receive bolts 7 1 which extend through the holes a sufficie'nt' distance bel w the lower fiangesof the beams A to admit of any'desired protective filling at this point.
spaces between eaclrcontiguous pair of floor beams are thus connected together, and the structure may be. completed, extending over the full width of the superposed flooring, and as all of these are supported by the plates 4, it will be seen that a sufficiently strong and rigid centering is thus formed.
' 'Upon the transverse portions 2 of the.
center plates, boards may be laid as at 8, and upon the sides between the inclined portions 2 and the beams, other boards '9 may be placed to form a support for the concrete, or other filling which occupies the space between and around the beams, and up to the level of their upper suifaces. Other boards 10 may be laid upon the bolts 7 and beneath thebeams so that a concrete filling may be extended below the beams, and thus form inclosing protecting and heat-resisting en velop for said beams.
Wl .concrete, tile, or other material (which is filled in in the plastic state) has become set and hardened, it is only necessary -to remove the bolts 7, disengage the plates 2 from the supports 4, and loosen the bolts 6 so that the metal plates may all be moved away from the concrete and the beams, when they can be hen the filling and super-structure of The sets of center-pieces which lie in the removed. The boards 8, 9 and 10 are then .easily removable, exposing the concrete or yfireproof surfaces beneath, and properly arched or shaped; it being understood" that the plates 2 may be curved or otherwise shaped to form any desired lower surface for the concrete. In this manner I am enabled to employ the same structure for repeated uses, andit may be readily fitted to any per-- manent structure upon which it is to be em- 'ployed, I
Having thus'descnbed my invention, what I ela'inrand desire to secure byluetters Patass,
and means whereby said extensions are adjustable on said plate.
in a centering like construction, the or K-beains, of adjustable over zipping plates extending edgewise between said floor or Ebeanis having bent portions projeeting downwardly contiguous to and below the lower flanges of the beams, bolts by which the lower ends of contiguous plates are con neeted together, supporting extensions lixcd to the plates and having their free ends bent to stand edgeivisc froin'tho plate and adapted to rest upon the lower flanges oi the 1- beams, and boards supported by the top and sides of said plates and by the bolts and adapted to receive and support a plastic lilling until said. filling has become set and hardened.
In testimony whe eof l have hereunto set my hand in presence of two suljlseribing witnesses.
