Description
WILLlZAM F. Henons'r, or sAn Linea, cAL ronnm. I
DRY-DOCK.
To all whom it may concern:
Be it known that 1, WILLIAM F. Honons'r,
a citizen of the United States, and a resident .of'San Diego, in the county of San Diego and State of California, have invented a new and Improved Dry-Dock, of which the following is a description. 1 My 'nvention relates to dry docks and more particularly to floating dry docks in which a float or caisson is open under side, whereby the water may be displaced therefrom by air under pressure to float'the dock. 1
The general object of my invention is to provide a floating dock of the character having characteristics and advantages as will appear.-'
' :Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention. I Figure 1 is a front view of a floating dry dock embodying my invention; V
. Fig. 2 is a partly sectional front view of a portion of one of the floatable sections;
Fig. 2 is a fragmentary vertical section showinga portion of one of the partitions in the float sections, and a check valve therein; Y Fig. 3 is a partial planfview of'a dry dock embodying my invention,
Fig. 1 is an end view of one of thescctions and relatively fixed guide racks therefor;
In carrying out my invention in accord:
-'-ance-'with the illustrated example, piers 10 vertical are provided. Separate floatalcle sections 11 are disposed extending substantially from one pier to the other; In order that the sections 11 in rising'and falling may be con- 1 (Upon the lowering ofthe sections air will strained to have a parallel movement and be prevented from tilting in any direction, fixed racks 12 are provided at opposed sides of the piers 10 and a train of intermeshing gears 13 is provided on shafts 14, extending lengthwise of each section 11.
The various sections 11 comprising the float in practice are adapted to receive a ves sel A to be supported on keel blocks B and bilge blocks C in the usual manner, said blocks and vessel being conventionally indicated.

a cut-off valve 19.- Vent valves'20 are cept the centrallones, and similarly in the partitions 15 vent valves or air valves '21 are provided near the top except in the central partition. The valves 20 and 21 may be including a spring-pressed ball valve 22; Thus, with the rising of the'float section for example under the displacement of the {water in the central compartments of the section, a vacuum will be prevented in the other compartments,
by air entering through vent valves 20.
pass through the valves 21 to the central compartments and outward through the inlet 16 and to the atmosphere at any point in the pipe lines hereinafter referred to. The piers 10 are provided with preferably conical air-storage chambers 23 and passages 24 extending from the chambers through the top of the piers whereby the said chambers may be connected with the float sections 16 to receive air therefrom and as later explained in the lowering of the dock sections. To supply air under pressure any suitable Source of compressed air may be provided,
In addition to the there being indicated conventionally an air compressor from which a. manifold or pipe line 26 extends along a pier 10 and branches 27 extend from said manifoldto make connection" with the respective sections. Permanent pipe lines 29 may be provided on each section 11 adaptedto be connected with the branch 27 by a hose'28.
Each branch has a two-way va-lve'30 which may connect a branch 27 with the hose 28- or permit outflow to the atmosphere through a discharge 31 in permitting the air to escape from thersection 11. Also, suitable V meansi'sprovided to connect up an air passage 24 of a chamber 23, with thesections 11,
one' means for the purpose being indicated in Fig. 1 wherea branch pipe 32 connects a branch 27 to a valve 33 leading to a passage 24: said valve being adapted to connect a passage 3-1 with the branch 32 or discharge to the atmosphere. t The described construction provides for establishing communication between the several compartments of a section to supply air under pressure thereto as desired or required under given load conditions and the supply and equalization of the air is eflected 7 while employing a single air inlet which makes for simplicity of construction and facility inthe, operation and control of the dock.
An advantage of a dock as described above also is that the floatable sections may be completely submerged and the dock then be utilized for commercial docking purposes, it
being necessary only that there be suflicient claim as new, and desire to se gure' by Let h rs Patent; v V V 1.
