ADJUSTABLE AND REMOVABLE CENTER-FOR ARCHES.
SPECIFICATION forming part of Letters Patent No. 598,083, dated November 2, 1897.
' Application fil d December 14, 1896. Serial No. 615,542. (No model.)
To all whom zit may concern.-
Be it known that I, THOMAS M. CLANCY, of New York city, in the county and State of New York,have invented a new and Improved Adjustable and Removable Center forArches, of which the following is a full, clear, and exact description.
The invention relates to the construction of floors of buildings; and its objectis to provide a new and improved center for forming a temporary support for the concrete or other filling to be placed between the adjacent floorbeams, the center being arranged to permit of placing it conveniently in position and adjusting it to conform to the shape of the intended arch. and to permit of readily removing the center from the beams after the arch is finished, leaving the arch perfectly smooth.
The invention consists of certain parts and details and combinations of the same, as will be fully describedherein after and then p0int ed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cate corresponding parts in all the figures.
Figure 1 is a sectional side elevation of the improvement as applied. Fig. 2 is an inverted plan View of the improvement. Fig. 3 is a sectional side elevation of amodified form of the improvement, showing it applied for forming straight arches; and Fig. 4 is an inverted plan View of part of the improvement shown in Fig. 3.
The improved center mainly consists of a sheet'A made of sheet metal or other suitable flexible material to permit of bending it to the form of the intended arch, the said sheet resting with its ends on the underside of the bases of the floor-beams B, as is plainlyindicated in Figs. 1 and 3.
The sheet A is provided on its under side with longitudinally-extending stiffening ribs or plates C, preferably made of flat iron, with the ends 0 projecting beyond the sheet and bent upwardly through recesses A in the end of the sheet to form lugs adapted to engage the back of the base of the corresponding I- beam B, so as to bring this end of the sheet on the corresponding I-beam- Openings C are formed in the other ends of the ribs C and the sheet Afor the passage of rods D, adapted to engage and rest on the top of the base of the other I-beam B, as is plainly shown in Figs. 1 and 3, the outer lower ends of the rods being engaged by the ends of cords or chains E, attached to staples F, secured to the ribs 0. The rods D extend in an -angular direction, as is plainly shown in Figs. 1 and 3, and are held in this angular position by the cords or chains E, so that this end of the sheet is securely held to the under side of the I-beain B. Angle-irons G and H are attached to the ends of the sheetAbetween the ribs or plates 0, so as to stiffen the sheet at the ends without impairing its longitudinal flexibility to permit of bending the sheet into the shape of the intended arch.
Now in order to apply the center I first place the ends 0 upon the base of one of the I-beams B, then extend the sheet to the other 'I-beam and press it upward by pushing on the angle-iron H until the sheet is bent to the form of the intended arch. "When this has been done, then the rods D are inserted through the openings Gflnext to the base of one of the Lbeams, and the rods are pushed up so that their upper ends rest against the I-beam, and the lower ends are held in an angular position by attaching the free end of the cords or chains E to the lower end of the rod. In doing so the rods D are securely held in place and lock this end of the sheet A to the under side of the corresponding I-beam. The space on top of the center thus formed between the I-beams B can 110w be readily filled with concrete or other suitable filling material and when set and dry the operator simply disconnects the ropes E, pulls out the rods D, and then draws the sheet A downward to pull the lugs C out of the concrete and from the base of the I-beam B.
For forming straight arches, as shown in Fig. 3, I prefer to employ a sheet A. having the ribs 0 made of angle-iron for stiffening the sheet longitudinally, as indicated in the said figures, the construction and arrangement of the sheet being the same as above described and fastened in precisely the same manner to the I-beams B.
Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- 1. A temporary center for forming arches, comprising a sheet capable of being formed into arch shape, fixed angular lugs on one end 7 of the sheet for hanging it upon the base of floor-beam and means for holding the said support in position from the said sheet, substantially as shown and described.
3. A temporary center for forming arches, provided With a flexible sheet adapted to be bent to the shape of the intended arch, and adapted to rest with its ends loosely on the under side of the floor-beams, stiffening-ribs attached to the sheet and projecting at one end to form upturned lugs for engaging one of the floor-beams, and rods suspended from the sheet and adapted to pass through openings or slots in the sheet "to engage and rest on the other floor-beam, substantially as shown and described. 7
