GAISSON CONSTRUCTION.

Specification of Letters Patent. Patented Apr. 30, 1912- Application filed July 31, 1911. Serial No. 641,609.

To all whom it may concern:

Be it known that I, EDWARD BIGNELL, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements'in Caisson Construction, of which the following is a specifica- Another object. is to provide cylindrical eaissons of any desired length or diameter which may be lowered or sunk quickly, or without undue loss of .time, and with less expense for labor than usual.

The herein described caisson is particularly adapted for use in ordinary siltdeposits, sand, gravel, clay or any other soil where boulders or like obstructions are not likely to be encountered.

\Vith the above objects in view and others hereinafter mentioned, the invention'consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the drawing, it being understood that changes in form, size, proportion and minor details may be madewit-hin the scope of the claims, without departing from the spirit of the invention or sacrificing any of its advantages.

In the accompanying drawing, which illustrates one embodiment of my invention,

Figure 1 is a vertical longitudinal section of a caisson, taken on line a a of Fig. 2, parts] .being broken away to more clearly show construction. Fig. 2 isa plan View of the caisson, being atransverse section on l1ne b b of Fig. 1. Fig. 3 is a transverse section on line a c of Fig. 1; Fig. 4 is a detail relating to Fig. 1, showing a passage: way through the operatingwhe'el.

Referring now to the drawing for a more particular description, the body of the caisson consists, principally, of two cylindrical receptacles,'4.- and .5, which may be constructed to advantage of sheet metal, their uniformly, or substantially so.

and partitions operate to strengthen the 1t may sustain stresses,

' the number of side walls and bottoms indicated at d and e.

Receptacle 5 has-a less diameter than receptacle 4., and is disposed therein to pro- .vide the annular chambers 6, 7 and 8 between walls d and separated by partitions 9.

At 10 are indicatedbraces disposed transversely of the annular chambers, between walls d, and between the bottoms of the ,re ceptacles, so that they may be spaced apart The braces caisson so that strains or lateral pressure.

" While I have described threeannular.

chambers I may employ more or less, and

the length or diameter of the caisson, and

these dimensions may be varied, also the chambers may have any suitable width. At 11, near the bottom and within the inner receptacle 5, and secured-thereto in any suitable manner, is indicated a transverse support1ng-bar or brace having a col-.

lar 12, and a similar bar or brace 13 may be employed at'the upper end of the caisson.

At 14 is indicated a tubular shaft disposed at the middle of the caisson and suitably journaled in bars 11 and 13, its collar 15 being supported upon collar 12 of bar 11; and

rollers or balls 16 may be employed between these collars, if desired, so that the shaft may rotate without undue friction. is

'Since the shaft traverses Wallsor bottoms e, suitable apertures 17 are provided in these parts for this purpose. Disposed be- ,low the caisson and rigidly the shaft is the cone-shaped, hollow drillmounted upon chambers will depend uponbeing respectively head 18. It should have. a diameter somewhat greater than that'of the caisson, and its downwardly convergent wall is formed with numerous perforations 19 and is provided with ridges or fins 20.

Upon the upper terminal of the shaft is.

mounted the operating wheel 21 which may.' be actuated by any suitable means to cause. a rotation of the drill-head. Any suitable means may be provided so that air or water under pressure may be discharged from the stationary supply pipe 22 within the tubu lar shaft- 14, the means herein shown being the usual apertured ball 23 rigidly mounted upon the pipe and seated in socket 2a, the socket being formed in platform 25, this platform being mounted upon the upper 10 said chamber to porting-bars; a tubular member longitudinally traversing the receptacle and journaled in the supporting-bars, said tubular member having a discharge port below the bottom of the receptacle and providing a passageway for a fluid element.

5. caisson comprising a cylindrical, outer receptacle formed atlongitudinal intervals with perforations, a cylindrical receptacle provided upon its inner wall with sup orting-bars and disposed within the per orated receptacle to form a chamber therebetween; tubular members disposed in provide conduits for the passage therein '0 a fluid element; a rotatable shaft longitudinally traversing the receptacles and journaled in the supportingbars; a hollow drill-head having a tapered perforated Wall, said drill-head being disposed below the outer receptacle and mounted upon the shaft; said shaft and drill-head providing a passageway for a fluid element.

6. An improvement in ,caisson construction, comprising an outer, elongated receptacle formed with perforations in its bottom and side walls; a second elongated receptacle disposed within the outer receptacle, a plurality of partitions disposed transversely at longitudinal intervals of and between the receptacles to form chambers; and a plurality of conducting pipes having discharge ports disposed within and adaptgd to convey a liquid element to said chamers.

7. An improvement in caisson construction, comprising an outer, drical receptacle formed with perforations in its bottom and side walls; a second,'u right, cylindrical receptacle disposed within the outer receptacle, a plurality of partitions disposed transversely at longitudinal intervals of and between the receptacles to form chambers; a plurality of conducting pipes having discharge ports disposed withm and adapted to convey a liquid element to said chambers; a tubular shaft provided upright cylin-' conveying a liquid element.

8; An improvement in caisson construct1on, compris ng a cyllndrlcal receptacle formed with perforations in its bottom and 4 side walls; a second cylindrical receptacle disposed within .the outer receptacle, a plurality of partitions disposed transversely between the receptacles to form a plurality of chambers; and a plurality of conducting pipes adapted to convey a liquid element, said pipes having their discharge ports disposed within said chambers. I

9. An improvementin caissons, comprising, in combination withan outer, upright cylindrical receptacle formed with perforations in its bottom and upright cylindrical receptacle disposed within the outer receptacle, a plurality of partitions disposed transversely between the receptacles to form a plurallty of chambers; a plurality of conducting pipes adapted to convey a liquid element and having their discharge ports dis osed within said chambers; a tubular shaf t provided at one of its terminals'with a cone-sha ed hollow drill-head with perforations in its tapered wall, said shaft being disposed substantially in the axial planeand traversing said receptacles with its drill-head disposed below the bottom of the outer receptacle,-said shaft and drill-head for the passage therethrough of a liquid element.
