JOHN ONEIL, OF NEV YORK, N. Y.
TEMPORARY CENTER.
SPECIFICATION forming part ot' Letters Patent No. 710,505, dated October '7, 1902.
Application filed April 19. 1902.
To rl/ZZ wtrmt ntftg/ cm2/cern:
Be it known that l, JOHN ONEIL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and usefnl Improvements in Temporary Centers, of which the following is a specification.
My invention relates to improvements in temporary centers for use in the construction of doors and ceilings of blocks, concrete, or other filling material, and has for its object a centering device which Vmay he readily removed when desired; and for this purpose it consists of the combination and arrangement of parts constructed as hereinafter set forth and claimed.
In the drawings which form part of this specification, Figure 1 is a vertical longitudinal section of a portion of a floor with the centering device in operative position. Fig. 2 is a plan view of the centering device in place on the beams previonsto the placing thereon of the blocks or tiles and filling in of the concrete or other material. Fig. 3 is a perspective view of the centering device on an enlarged scale from that shown in the other figures and with the parts bolted together. Fig. 4 represents a side View of one of the bars or parts shown in Fig. 3; and Figs. 5 and 6 are plan views of the two parts, respectively, forming the device.
Similar numerals indicate like parts in the several views.
In the drawings, 1 1 designate floor-beams, consisting of I-shaped sections, between which the tiles, blocks of concrete, or other material 2, comprising the door, are disposed in the form of an arch.
The centering device or center 3 is for the purpose of temporarily spanning the space between the beams, so as to support and hold securely in place the blocks or floor material while the same is being placed in position between the beams.
In my invention the center 3 consists of two iiat bars or strips 4 and 5, respectively, adapted to overlap at their inner ends and be connected thereat by headed bolts 6 6, with clamping-nuts thereon. Each of the said bars is composed of resilient metal or wood and formed with an upturned end, constituting a foot 7, which is adapted to abut against semi No. 103.306. No modus,-
or rest upon a flange S of one of the floorbeams, so as to aid in supporting the har in place. One of the bars, as 4, is formed with a slot or elongated opening 9 near one end thereof, and in line with said slot it is provided with a series of perforations or openings 10 for a purpose hereinafter explained. The other bar 5 has an opening 11 therein, near one end thereof, adapted to register with either one of the openings 10, and interme diate of said opening 11 and the other end it is provided with an opening 12, adapted at the same time to register with the slot 9 in the bar 4, so that the bars may be longitudinally adjusted relative to each other, thereby regulating the extent of their span, and thus accommodating them to iioors having beams of different distances apart.
The bolts 6 have their heads countersunk in the upper face of the bar 4, the shank of one passing through the slot 9 thereof and the opening 12 in bar 5, and the shank of the other bolt passing through one of the openings 10 in the bar 4 and the opening 11 in the bar 5. Nuts 14 are placed on the threaded lower ends of the bolts and screwed tightly against the under face of the bar 5, thereby clamping the bars together and holding the ends thereof in fixed position.
A number of pairs or sets of bars may be placed side by side or plates or strips of metal, wood, or other suitable material may be placed or supported on separated pairs of said bars, so as to sustain in place the block, tile, concrete, or other filling while the same is being placed in position, or the blocks may be supported directly at their ends upon the bars.
When it is desired to remove the center, the nuts 14 are unscrewed from the bolts and the lower bar 5 then detached from the bolts and upper har, after which the other bar 4, with the bolts, can readily be removed and the two bars again placed elsewhere in open ative position, if so desired.
It will be apparent that a center of the construction herein set forth is economical in'character and easily operated owing to its simplicity. Its easy adjustment and ready removal are of practical value, as saving time and aiding in efficiency.
Having thus described my invention, what roo I claim, and desire to secure by Letters Patent, is-
l. A center, Consisting of two bars, one of which has a slot therein near one end thereof, and intermediate of its ends provided with a series of openings; and the other bar having an opening therein near one end thereof adapted to register With any one of the said series of openings in the first described bar and another opening which registers with the slot aforesaid, and bolts adapted to be inserted in said registering openings, substantially as described.
2. A centering device, Consisting of tWo bars of suitable material having overlapping ends with registering openings and provided With clamping nuts and bolts, each of said bars having an upturned end forming a foot, said parts being combined substantially as described.
3. A centering device comprising two arched bars et and 5, the end of one bar overlapping the other, and each of said bars having a foot and a plurality of openings, and bolts and nuts for adjnstably securing the overlapping ends, the heads of said bolts being countersunk so that the surface of the blocks of concret-e or other material may lie in Contact with the convex surface of the bar 4 when the blocks are in position.
In testimony whereof I affix my signature in presence of two Witnesses.
JOHN ONEIL. Witnesses:
