Claims. (Cl. 114-.5)
This invention relates generally to structures supported by floating pontoons and in particular to a simplified, demountable pontoon supported structure which permits ready access to the pontoons to facilitate their repair or replacement.
In conventional pontoon supported structures, such as floating docks, rafts, temporary bridges or the like, the pontoons often take the form of metal barrels or drums held in position by a permanently assembled framework including side'beams and cross braces. Considerable time is required in assembling such frameworks and should one of the drums or barrels develop a leak, the whole structure must be dismantled to gain access to the bun opening of the faulty drum for pumping water therefrom.
It is the primary object of the present invention to provide a pontoon supported structure which is of simplified structure and which permits ready access to the pontoons for repair or replacement;
It is a further object of the present invention to provide a pontoon supported structure utilizing detachable brackets or hangers to attach the pontoons to side beams so that the pontoons themselves act as cross braces for the structure.
The full nature of the invention will be understood from the accompanying drawings and the following description and claims:
Fig. 1 is a fragmentary perspective view showing a partially assembled structure embodying the present invention.
Fig. 2 is a bottom plan view of a component of the structure.
Fig. 3 is a side view of the-component shown'in Fig. 2.
Fig. 4 is a top plan view of the component shown in Fig. 2.
Fig. 5 is a perspective view of a further component of the structure.
Fig. 6 is a perspective view of a portion of the structure shown in Fig. 1.
Fig. 7 is a perspective view of a completed structure embodying the present invention.
Referring initially to Fig. 1, there is shown a portion of a floating dock structure or raft assembly embodying the present invention and including aligned pontoons which may take the form of metal drums 10 and 11 having bung fittings 10a and 11a. The drums are of conventional type and at each end are provided with beads 12 which extend axially beyond the end faces of the drums. The assembly includes support beams 13 (only one of which is shown in Fig. 1) which extend in parallel relation across the aligned end faces of the drums and adjacent their upper margins.
The means for securing the drums to the support beams 13 comprise central hangers 1'4 and side hangers 16, the end of each drum being secured to one central hanger and two side hangers. It will be understood that by attaching side hangers to one end of the drum and a central hanger at the drums opposite end, a three point suspension of the drum may be provided. Similarly, two or more side nited States Patent Office 2,962,996 Patented Dec. 6, 1960' hangers only might be used at each end of the drum to provide a multiple point suspension. 1
Each of the central hangers 14 includes an L-shaped bracket 17 which is apertured at 18 to accommodate nails, screws or bolts for rigidly fastening the bracket to the support beam 13, as indicated in Fig. 1. The under face 19 of the leg 21 forming a part of bracket 17, has a slightly curved configuration, as indicated in Fig. 2, so as to accommodate the curved surface of the drum. The under face of the leg'21 is also provided with a groove 22 which is sized so as to accommodate the bead 12 of the drum. A clamp stop 23 is formed in the bracket and is positioned to one side of the center line thereof as indicated in Fig. 2. Adjacent the clamp stop the leg 21 of the bracket is provided with an aperture 24.
In Fig. 4 there is shown in place within the aperture 24 the generally L-shaped clamping member 26 which is threaded to receive a nut 25 and is provided with a sidewardly extending portion 27. The shank of the member 26 extends freely through the aperture 24 and by displacing the portion 27 from its position of Fig. 4 to a position clockwise therefrom so as to extend across the groove 22 and by subsequently tightening nut 25 the bead portion of the drum may be locked within the groove. The stop 23 defines this clamping or looking position of the portion 27.
Each of the side hangers 14 includes a dual-jawed clamp comprised of an L-shaped bracket 31 having an aperture 32 in one leg thereof. A bolt 33 extends through the other leg of the bracket and through a clamping plate 34. The leg accommodating bolt 33 is notched, as indicated at 36, to accommodate the bead portion of a drum. As may be seen in Fig. 6, the side hangers also include a plate 37 .which is adapted to be rigidly mounted on the support beam 13. Bolts 38 (Fig. 1) are utilized to secure the brackets 31 to the corresponding plates 37 at the desired angle of extension.
The relative positioning of the central hangers and the side hangers will be evident from Fig. 1. With the central hangers 14 and the plates 37 secured to the support beams 13, as shown in Fig. 6, the side hanger assemblies may be completed, the members 26 moved to clamping position in the central hanger assembly and the nuts 25 tightened. In the rigid structure thus provided the drums themselves act as cross braces. 'The assembly may be completed as indicated in Fig. 7, by placing a conventional slatted floor structure 41 across the support beams 13.
By arranging the drums so that their bung fittings are top side, access to the interior of the drums may be had by removing the floor structure 41. As will be evident from Fig. 1, the direction of extension of the brackets 31 from the plates 37 may be varied so that the structure may accommodate support beams of various depth. The structure may be assembled and disassembled conveniently, requiring the use of only a properly sized wrench.
While the invention has been disclosed and described in some detail in the drawings and foregoing description, they are to be considered as illustrative and not restrictive in character, as modifications may readily suggest themselves to persons skilled in this art and within the broad scope of the invention, reference being had to the appended claims.
