FALSE WORK FOR BUILDING CONSTRUCTION.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed March 9, 1909. Serial 110.489.3165.

To all whom it may concern:

Be it known that I, ALBERT ARNN, a citizen of the United States, residing at Little Ferry, in the county of Bergen and State of New Jersey, have invented new and useful Improvements in False WVork for Building Construction, of which the following is a specification.

This invention relates to false work for concrete construction and consists of telescopic metal work adapted to be suspended from beams or built up about a common center and made adjustable so that it may be properly located and adjusted, and then covered with sheet metal to form the mold for the plastic concrete and after the same sets and dries the false work is collapsed and the sheet metal removed, which with other details and objects will be more fully explained in the following specification set forth in the claims and illustrated in the drawings accompanying this application, and where:

Figure 1 is a sectional view through a concrete flooring and the beams supporting same and showing the false work in position. Fig. 2 is a view along the face of one of the beams and at a right angle to above. Fig.3 shows the construct-ion of an arched ceiling by the use of the device. Fig. 1 is a view through the line 11 of Fig. 1. Fig. 5 shows how the device may beadapted for use in concrete conduit construction. Fig. 6 shows its adaptation to stairway construction. Fig. 7 illustrates the construction of a column. Fig. 8 is a view of the sheet metal molding plates. Fig. 9 shows the method of suspending the plates from a channel beam. Fig. 10 is an enlarged view of a suspender.

The device is adapted to be suspended from the beams 10 by means of the hooks 11 and 12 whose upper ends engage the flanges of the beam while the lower end of the hook 11 is flattened and perforated as at 13 for the reception of a pin 11 which presses from side to side and is adapted to carry a suspender 15 with the slot 16 for the flattened portion of the hook 11. The suspender 15 comprises two hooks, the upper one engaging the pin 11 while the lower one is adapted to carry the pipe sections 16 and hold it firmly by means of the set screws 17. These pipes 16 telescope in larger sec- .tions 18 which carry one or more ties 19 which are connected by pipes 20 parallel with the beams.

In the construction shown in Figs. 1, 2 and 1 where angular construction is resorted to each beam 10 supports the usual metal rods 21 and carries the hooks and suspender 15. The sections 18 are supported at each end by the pipes 16 .and also carry .at the ends the ties 19 but the latter may be adjusted to produce a separation of any desired extent and they carry the upright sections 22 into which smaller sections 23 telescope and are held in place by the set screws 21. By means of elbows 25 the pipe sections 23 have connected the horizontal sections 26 and 27 the former telescoping with the latter.

lVhen it is desired to construct a flooring such as shown in the three views referred to the pipe sections are adjusted to fit the proper dimensions and on these are placed the folding plate sections 28 with the pins 29 on two sides and cooperating hooks 30 on the opposite sides, both being adjustable and the ends of the lower plates having notches 31 for the passage of the lower ends of the hooks 11. These plates now form the boxing shown in Fig. 1 and into same is placed the plastic concrete until the floor level is reached and it is allowed to set and dry when the sections 22 and 23 and 26 and 27 are telescoped and the frame Work they comprise lowered. The, suspenders 15 which have also supported the lower plate are removed and the whole pipe system taken out and the plates removed. This frame may then be used again for forms of this or other dimensions and is quickly and easily set up or removed and is a vast improvement over the old wooden false work construction such as heretofore used and which may be used but once and requires time and expense in erecting and removing.

When the molding plates are removed the flattened ends of the hooks 11 may be cut off or used to attach metal ceiling panels, to support pipes or for many other purposes. In case it is desired to give the ceiling an arched effect, plates 32 curved to give the desired shape are hinged to the lower plates 33 and at their meeting place are supported by the telescopic pipe sections 31 and 35, the latter carried by the tie 19 and pipes 16 and 18 that are supported as usual.

Fig. 5 shows how such a frame work may be used in constructing cylindrical work as for sewers and conduits and the ties are carry the telescopic sections 37 and 38 which are adjustable and support plates 39 of any desired shape to receive the plastic concrete on their outer surfaces, all of which may be easily adjusted or removed and again put 1n use.

Fig. 6 illustrates the use of these pipe sections and couplings for building stairways or similar structures and Fig. 7 shows the hooks 11 and 12 applied to a .verticalbeam used as a columnand aroundwhich a concrete structure is being built within molding plates 33, hinged together and held in place by the-plns 14. V. 1

When a channel beam 41 suchas shown in Fig. 9 is used the plates are hung by means of ahook 42 which hangs over theupper edge of the beam and may be pulled out after the plates are removed.

It is obvious that various forms and construction of concrete may be resorted to by combinations of these plates, pipe sections and couplings and that modifications may be adopted in the construction of these parts without departing from the essential features above described.

What I claim as new and desire to secure by Letters Patent is:

1. In false work for building construction, plates having hinges and adapted to conform with the concrete structure carried by the beams of the building, frames made up of pipes and adapted to be adjustable to conform with the position of the plates to support same, and hooks adapted to engage the beams and support the frames.

2. In false work for building construction, the combination with frames made up of pipes telescoping within themselves so as to be adjustable, of hinged plates supported by the frames, bolts in the pipes to secure plates and same when adjusted, cooperating hooks to support the pipes, and connecting means between the hinged plates and the frame.

3. In false work for building construction, of hangers, hooks engaging the flanges of the beams and carrying the hangers, telescopic pipe sections carried by the hangers, adjusting bolts, angle couplings, and folding metal moldingplates supported by the telescopic pipe sections.

4. In false work for building construc-' tion, telescopic pipes, telescopic pipes connected with the first named pipes and adapted for vertical adjustment and for adjustment longitudinally of the first named pipes, angularly vadjustable plates supported by the second named telescopic pipes, and connections between a plurality of said hinged a plurality of the first named telescopic pipes.

5. In false work for building construction, of hooks attached to the beams of the hangers on the hooks, pipe sections carried by same, larger pipe sections telescoping over the first sections, angle couplings, and sheet metal molding plate sections hinged to each other and adapted to take the shape of the pipe sections.

6. In false work for building construction, of a collapsible frame made up of telescopic pipes and hung from the beams of the construction, molding plates supported by the frame, and adjustable cooperating pins and hooks to connect the molding plates to allow them to take the sha e of the frame.

In testimony whereof I a my signature in presence of two witnesses.
