DOCK.

Application filed .f nme 12, 192e,

to docks and more Adock for housing i so that vessels or aeroplanes of different heights may be accommodated while the device maintains at all times the lowest possible center of gravity. l

. A further object of the invention is to pro-i.

l vide a device of this character `which may elements 19, so that t e be readily dismantled to permit its shipment from placeto place.

These and other objects I attain by the construction shown in' theaccompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein j Figure 1 is a front elevation of a dock constructedin accordance with my invention; 4'

Figure 2 is a side elevation thereof; Figure 3 is a vertical sectional view on the line 3-3 of Figure 1.

Referring now more particularly tothe drawings, the numeral 10 generally deslgnates supporting fioats, at present illustrated as'closed chambers which air or gas, increasing the buoyancy of the chamber. By regulating the buoyancy ofthe chamber, the chamber may be submerged and thus hidden from view,if so desired. A chamber is arranged at each side of the dock and at each end thereof, each chamber is provided with vertically extending tubes 11 in which are en aged thelower ends of roof supports`12. each formed at their lower ends as racks 13 and leach tube 11 has rotatably mounted thereon adjacent'its upper end a gear 15 for engagement with the rack to vertically adjust the support 12. The gears may be pro vided with a removable handle 16 whereby they may be adjusted. Each tube has further pivoted thereto a pawl 17 for engagement in the rack to maintain the support 12 in'adjusted positions.

The numeral 17 generally designates a duralumin roof structure formed in sections '18. secured together b removable securing roof may be readily separated into sections for transportation.

aeroplanes or the` may either lcontain hese roof supports are p Serial No. 115,572. Renewed August 1'5, 1927.

The connections between the sections preferably embody braces 20 combining in the assembled roof to produce truss structures for supporting the roof. The roof structure is suitablyn secured to the upper ends of the supports 12 and braced therefrom, vas indicated at 21.

It will be obvious that a device of this character may be readily erected or dismantledfor shipment and willprovide a very elicie'nt vhousing for a boat, submarine or aeroplane in which'the roof structure may always be arranged at theplowest possible level, so that the center of gravity is always kept at the lowest possible point. In practice, the tubes 11 will be lilled with oil in which the rack 13 will extend to prevent corrosion of the teeth thereof, and to provide the necessary lubrication. The tubes 11 further `have secured thereto pivoted eyes 22 for the. passage of piles or similar anchoring devices or for attachment of an ordinary anchor. secured to each If desired, cables may be corner of the dock to provide `additional anchoring means.

Since the construction hereinbefore set forth 'is obviously capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

1. In a floating dock, spaced vfloats each provided at each end thereof with a vertically directed tube, a support vertically adjust-v able within the tube, means for holding the support in' vertically adjusted positions and a roof structure secured to the upper ends of the supports.

2. In a ioating dock, spaced' floats each lrovided" at each end thereof with a verticaly able within the tube, means for holding the support in vertically adjusted positions and a roof structure secured to the upper ends ofth'e supports, said roof structure Abeing formed in a plurality of sections secured to one another. v

3. In a floating dock, spared floats each provided at each end thereof with alvertically directed tube, a support vertically adjustable within the tube, means for `holdingthe directed tube, a support vertically adjustone another, the connectionsY between the sections combining in the completed roof structure to provide a' truss.

4. In a vfloating dock, spaced floats' each provided at each end thereof with a vertically directed tube, a support vertically ad- -justable Within the tube, means for holding the support in vertically adjusted positions, a roof structure secured to the upper ends of the supports and means for vertically adjustmg said supports comprising racks formed at the lower ends of the supports, a gear ro- In testimony whereof I hereunto alliA my signature.`
