Abstract: 204,018. Fortis Reinforced Concrete Safe Co., Ltd., (Assignees of Thorig, W. C.). Sept. 15, 1922, [Convention date]. Moulding safes and strong-rooms. - A reinforced concrete strong-room is moulded in situ and formed with walls for interior safes concreted integrally and concurrently with the surrounding walls of the strong room by the aid of rigid metal moulds. The base or floor 0 cf the strong room is first concreted, three layers of twisted iron bars F being introduced during the process, for reinforcement. The mould T for forming the seating for the strong-room door is then set up in a vertical position. This mould comprises angle corner pieces Te with wedge shaped top and bottom filling pieces Tk and similarly shaped side filling pieces Ts, these pieces being bolted to the corner pieces and permitting the mould to be taken to pieces and removed when the concrete is set. The mould is held in position by a wooden frame 11, 13 which also serves to support the sheeting for forming the part of the external wall U above the door and also the sheeting 21, which sheeting with the board 20 and moulds K<3> for the adjacent safe forms the. complete mould for the concrete wall N<1>. The iron frame q<1> fixed to the outer face of the door seating, the iron frame y<1> fixed in the niche of the seating and the stop frame x are securely held in their correct positions during the concreting by eccentric pins E<3>x, E<4>x, and E<5>x respectively, carried by the mould T. Hooks h<3>, h<4>, h<5> respectively attached to these frames securely hold them in the set concrete. When the surrounding wall U and strong-room door seating has been constructed, the sheeting is removed and the moulds for the series of adjacent safes and their separating walls and door seatings are set up. Two such moulds are shown in Fig. 5. These moulds K<2>, K<3> are set up in vertical position and con. sist of angle corner pieces Ke with wedges Kl for easy removal. The parts Ke form the seating for the safe doors. Secured to these parts by wing nuts fl screwing on to bolts passed through flanges We are plates Ho, Hs, Hu forming the mould for the walls of the safes. To ensure that the comers of the safe are square, a filling piece E with a square edge is clamped to the plates by screws Sch passing through bridgepieces B engaging bevelled extensions Z on the plates, Fig. 6. The reinforcing A<1> of the safe walls W<1> takes the form of a rectangular metallic chain work, the outer links of which are engaged with the bars F of the outer wall reinforcement, Fig. 2, gaps Sp<1>, Sp<2>, Fig. 5, being left in the outer wall for effecting this during the concreting of the safes. The roofs D of the safes are similarly reinforced. Metal frames q, y, which are similar to the frames q', y<1> of the strongroom door seating, are held in position in the safe-door seatings by eccentric pins E'x, E<2>x respectively during concreting, and by hooks when the concrete is set. The hinge members v on the door seating are held in place during concreting by members ax secured to the moulds. The board 18 forms the end sheeting for concreting the roof and the board 19 for the floor, and moulds being supported on blocks S'o - - S<3>o. When the concrete is set, the boards 18, 19 and the supports 1, 2, 3 are removed and the spaces between the blocks filled in with concrete, reinforcing bars F being added. Chambers may be formed between the tops of the safes and the roof C of the strong room for ventilation, pipes R<1> providing inlets and outlets and holes L giving access to the interior of the strong-room. The metal sockets n on the door frame into which the bolts fit when shut are held in position during concreting by screws jk passing through the mould, Fig. 5, and are provided with hooks h for securely embedding them in the concrete. The safe doors are reinforced by an interengaging metal chain-work of triangular formation with vertical strengthening rods. The strong-room doors are similarly reinforced with the addition of the rectangular formation of chainwork as employed in the safe walls. A strong box t with ribbed steel bands is fitted into the top of each safe, Fig. 3, and shelve-s b can be supported on pegs adjustable on the supports a. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the door mould shown in Fig. 5<a> (Cancelled). These moulds have eccentric pins E<III>x, E<IV>x, for holding the iron frames u, z, which engage with the frames q, y on the door seating to exclude fire gases, in position during concreting. Rods r provide the holes in the door for the permutation lock mechanism setting spindle, keyholes and operating handle. To enable the mould to be used both for right and left hand doors, an extra rod r is added so that by suppressing the lowermost rod and inverting the door when set, the mould can be adapted for making a door of either band. To provide for the holes in the flange V of the strong-room door. through which the bolts i pass, a tube u, Fig. 5<c> (Cancelled), is secured in position by a plug bz held by a nut it. This subject-matter does net appear in the Specification as accepted.
