This invention relates to improvements in caisson construction and, more especially, such construction for making. foundations. Myinvention may be utilized, for example,

in the making of piers, foundations, supports,

and the like, for buildings, bridges, and other structures. Such supports or foundations frequently must be sunk to great depthsy in the earth and it is necessary or advisable'to first sink a cylindrical caisson to the desired depths. The caisson is then` filled withconcrete which solidiiies to make the permanent` support or foundation.

Among the features of my invention the` provision of such caisson construction made of cylindrical sections, thus facilitating hanf dling of the same. Means are also provided for joining the sections together vas thesame are lowered or sunk into the earth.

Another feature 'of my inventlon vis the provision of an improved shoe member adapt-g rounding earth. In connection w1th thls construction, I provide holes through the wallsv of the sections through which water, oil or grease maybe ejected. Thisvwater fills the and thus facilitates their 'downwardmovement. v r

Other features and advantages of my invention will appear more `full-y as I proceed with my specification.

In those forms of devices embodying the features of my invention shown in the accompanying drawings- Figure 1 is a vertical sectional view; Fig. 2 is a fragmentary view on an enlarged scale similar to Fig. 1, showing more details; Fig. 3 is a top plan view; Fig. 4 is a sectional view taken as indicated by the line 4 of Fig. 3; Fig. 5 is an enlarged vertical section showing the oint between two retaining rods; Fig.

Thei to leave spaces therebetween adapted to be lmember and for-attaching the sections tospace surrounding the walls of the sections 6 is a top plan view showing amodified form of construction; Fig. 7 lis a similar viewin side elevation; Fig. 8 isa view partlyin side elevation and partly in vertical section showing another'modiication.; Fig..9 is asimilar view in top plan; F ig. 10V is a top plan viewof another form; and Figs. 11 and 12 are" vertical sectional-views showing details of the'same. f" a Asshown inl the? drawings, 10 indicates aV cylindrical cuttingshoe orshoe member hav-l i ing` a cutting Y edge 11` .(pointe'd i in cross-secf tion).- The upper part of the cutting shoe 1s slightly -reduced in diameter,'as indicatedk cutting shoe'is preferably of a ldiameter large enough to allow'a workman, or excavating ap; i

parat-us, or both, towork insideof the same.y In the practice of the* invention, the earth 14 is removed from inside .ofV the shoe and as this continues, the shoe moves downwardly..

It is-to be vunderstood that'the shoe mem- -.ber 10-is preferably of'rather heavy mate-- rial, for example, wrought iron.

On top ofthe shoe member, I provide al plurality of cylindrical caisson sections.

These sections are builtfup on the shoe mernberlO as it is lowered.kr Means are providedl forattaching the bottomsection to theshoe gether. 1 y

I shall iirstdescribe that form of the invention shown in Figs. 1 to 5, inclusive... As here shown, each of the caisson sections vis lcylindrical lin shape, as indicated jby 15.

These'sections,for`example, may be made of concrete.- The shoe member 10 is Uprovided on its upper surfacewitha circular groove or trough 16. Numerals 1,7, 17 indicate nipples ,projecting upwardly from the bottom of this trough. The-'lower edgey of each shoe section'l is4 preferably somewhat pointed,

as indicated by -15,to conform in shape to the trough 16.l rIhe wall of each of the shoe sections 1 5 is provided with vertical holes containing tubular sleeve members 18 for the reception of retaining bolts 19. vNumerals 2Q. 20 indicate nuts screwed onto the nipples l17 in theshoemember'to receive the lower.. ends1 of the bolts119 for the? purpose'ofholdf lower ends of some of these bars aresuitablyg anchored in thel shoe 33.-.;v The upper .ends ot Y thebars 34- project` above theglowermost seca iiig the first shoe section 15 in position. The sleeves 18 are somewhat shortened at the lower ends and the bolt holes somewhat enlarged to receive the nuts 20. The upper edge of each shoe section 15 is also provided with a. trough 21 similar to the trough 16 in the top of the shoe. Numeral 22 indicates a spacing washer inthe trough 21'on the top of each shoe section in order to space the next section above away slightly to provide the cracks or spaces 23 whic i are illed with suitable packing 24. The spacers 22v may be continuous circular washers or a separate washer may be provided Vvfor each bolt.

In order to hold the sections'together, there is provided a nut 25 on the upper end of each bolt. This holds the section below it down and also provides a socket for holding `the-lower end of the next bolt 19 above. In this manner, -therespective sections are set work .progresses andV thezshoe member l0 descends, new sections 15 may beadded` at the verticalhole in each of the sections containing the sleeve 18 is somewhat enlarged at the lower '.eiid, as indicated by 26, and the lower end of. the sleeve18 some-what short-y cned, to form a space to accommodate thej nut 25 as the sections are joined-together This construction is similar-.tothe construc-` nut 20at the shoe member. '1`

Each of the sections is provdedrwith radial pipe or pipes 27 througlilthe .Wall hav;y ing a check valve or valves 28. rI he pipe 27 is adapted to receive a water hose 29 so that a stream or jet of water, oil or vgrease 29v Y lied forni of construction in which veach of 32 correspond'to'the bolts 19.- It' is tobev understood that the other details of thev lform shown in Figs. 6 and' are similar to those shown in Figsl to 5, except that cast conlcrete blocks amJ used to build up the sections.V

AIn Figures 8 and-9, I have shown anotherl 2 modification, in which the concrete sections are cast in situ. In this form of device, there is employed a cutting shoe- 33 similar to the? shoe 10. Projecting reinforcing bars 34 are used to connect the lowermost section 35 to f the shoe 33, .itbeing understood that the said means gether. As here shown, the upper edge of onesection 38 is provided with the trough 39, iii the bottom of which is placed a circular strip 40 provided with keyhole slots or openings 41. Theilower edge of a caisson section 42 next aboveis provided with depending bolts 43 having'heads 44 adapted to be -located inthe keyhole slots 41 by aslightrotary. motion of the upper section, inthe usual manner. Two sections 42 vand l 38 areshown locked together in Fig. 12.y together and 1t is to be noted that as thek lllhile I have shown and described certain iications. Changes, therefore, in the con-f struction and' arrangement. may be made i embodiments of my invention, it is to .be understood that it is capable ofmany modithe top of the structure. As has been stated,

withoutdeparting from the spirit and scope oftheinveiitioii as disclosed inthe appended claim, in which it is my intention to claimv all *novelty inherent in my invention as broadly as permissible, in` view of the prior art." Y. tion above described foriaccominodatingtlie v lVhat I regard as new, and desire 'to'secureb-yLetters Patent, is:

In caisson construction; a cylindrical cutting shoe with upwardly projecting-nipples;

adapted to be stacked up on said shoevmeinber as the sa'meis lowered; means lfor attaching the bottoni section to the shoe member, including bolts extending through thuewall of said sectionv adapted to be screwed into said-above-mentioned nuts ;y andineans'for attaching the sections to -gether, said means including nuts adapted to be screwed on tothe upper ends oi. theabovementioned bolts,- said Anuts engaging' the upper surfaces otsections, the )lower ends of bolts in the walls of sections above adaptedl to be screwedinto said nuts.

In witness whereof, I have hereunto set my hand this 3rd day of April, 1931. l THOMAS BYRNILVJR'.
