To all whom 'it may concern:

Be it known that I,`LoU1s E. VViaLsi-na citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Iiles, of which th following is a specification.

My invention relates to certain improvements in piles of concrete, or preparatory piles which are driven into the ground and removed so as to allow the opening to be filled wit-h concrete.

The object of my invention is to provide means for properly jetting a shouldered pile into the ground; the jets'of water disturbing the ground at the shoulders as well as at the point of the pile.

In the accompanyingdrawings Figure 1, is a sectional view of a shouldered pile illustrating my invention, the pile in this case being provided with an inner and an outer form, the inner form being the driving form; Fig. 2, is a sectional view illustrating a solid concrete pile made in accordance with my invention; Fig. 3, isa sectional view illustrating a shouldered driving form and a shouldered easing adapted to be driven into the ground, the driving form being then removed; Fig. 4, is asectional View showing the driving form removedand the casing filled with concrete; Fig. `5, is a sectional view vshowing the inner and outer forms, each made of shells connected together by rings; the outer rings forming shoulders and having jet openings; Fig. 6, is a sectional view of a pile in which the outer driving form is made up of concreteA shells separated i passageway d extending throughout the by metallicrings, providing shoulders and having jetting openings at the rings; Fig. 7, is a sectional view showing `a pile which can be both driven and jettedy simultaneously; the outer form being a continuous shell.

Referring in the lirst instance toFig. 1, A is the out-er form, B is the inner form.

-The outer form has a point a and `a series` of shoulders a', a2/there may be any number of shoulders, depending upon the lengthof the pile and the area of its upper surface. The outer form also has inner shoulders upon which rest the flanges b, b, of the inner form, the lower stem of the inner form rests on a shoulder b2 at the point of the pile. Formed in the point is a series of jet passages c communicating with a central length of the inner form and at the shoulder a are jet passages c in the outerforni which communicate with passages da, in the inner foriu, which in turn communicate with a passage nl extending to the butt end of the pile, and f, f are jet openings at the shoulders a2 which communicate with passages cl* in the flange b of the inner form B, and these passages communicate with the passage d2 yleading to the butt end of the pile. The flow of water through each of these passages is preferably controlled separately by a suitable valve, as illustrated in Fig. 2 for instance, so that when the pile is driven `the passages d .and d2 are cut off and the passage Z opened until the pile sinks to the lirst shoulder a', then water is admitted to the passage d as well as the passage d until the pile sinks to the second shoulder a2, then the third passage d2 is opened and the pile driven to theV proper depth. y

I have shown the outer form A made of concrete which may be reinforced in any suitable manner if desired, and the outerform remains in the ground after the inner form is withdrawn and the outer form can be illed with concrete and reinforcing material, although in some instances if the form illustrated in Fig. 1 is used as a preparatory pile and the character Vof the ground will admit of it, the outer forni as when'the pile is not to be withdrawn, thel central passage d in the present instance communicates with passages c, c in the head as. which surrounds the central tube Z and communicates with they 'jet openings e at the shoulder a and the outer passage 2 is formed by a still larger tube and communi- Cates with the jet openings f at the shoulder a2. Each of the pipes is provided with suitable valves for regulating the flow of jetting uid. This pile is jetted into the ground and remains therein7 the tubes can be withdrawn if' desired or may remain. as a reinforce for the pile. A

In Fig. 8, I have shown a shouldered pile The passage d is formed by a tube` t', z", vii-'each section z' Aitself 1and tubes g2, gs are attached tothe pile so as to communicate independently with said passages, the central tube d, as in the other figures, communicates with the passa e c in the point of4 the ile.

is made in 'sectons and i2 having inturned flanges' formin shoulders at their innerends and these anges'stop' shortv of the adjoining section so as to form the jet openings at the shoulders. The'passages g, g communicate with the jet openings thus formed so that Huid will be forced 'out at ile to sink.

casing I and `this casing After the casing has reached t e de th desired then the form-A2 is withdrawn, caving v the shell I within the ground, as illustrate jet o enings for disturbin Fig. an jetted simultaneously; ,water being lso in Fig. 4, and this shellis lled with concrete, as shown in said figure, in .any suitable I'nanner.

In Fig. 5, I have shown. a pile in which the outer form A* is made up of aseri'es of shells m connected together by shouldered rings n and in these shouldered `rings are the the ground at the s oulders. The inner orm B' is made up of a series of tubes la connected together by rings k which bear upon the inner shoulders of the outer form. The point Chas shoulders upon which the inner and outer driving forms rest and also has passa es c for the .jettin'g water and an inner tu d communicates with these openings as sin 1. This form of pile can be both driven a mitted to the 'et openings at the several shoulders as sald shoulders reach the level of the ground.

.In Fig. 6, I have shown a construction somewhat similar to Fig. 5, with the exception that the shells m are of concrete and are vpreferably loosely connected to the shouldered ring sections n which `havejet fluid passageways .connected by -pipes leadingto the butt end of the pile. The inner form B2 is made up of a series of metal tubes k2 screwed into rings 7c which rest against the inner flanges on the ring sect-ion n.

' ders. The inner In Fig. 7, I have shown another form of pile which can be driven and jetted into the ground;` Inl this pile the outer form a5 is made of a continuous tube having shoulders at intervals and et openin s at the shoulthe pille, but atthe sev Surv eug'round the earth will roun lng the outer pile A2 is'a thm metallic sho under as` peint and against the body of the pile, thus materiallyl il the supporting capacity of the up e. y

orm 1s ma e similar to the 5, and there is an independent at the shoulders, that' not only cart h disturbed directly under the point of shoulders m order that-the ile can be readily into the und y jetting, yet w en the -pile is in p ack under the ders as well as increasing While I have showntheseveral .zones ben tween the shoulders of an even diameter throughout, it will be understood that thty may -be tapered and, in some instances,

ile may have, the lower section 4-of an even diameter throughout and the uppersection ta' red without departing p ti features of the invention* I' I claimz- 1. A'pilehaving a plurality of shoulders successively increasing in diameter from the point to the butt, said pile having jet passages with outlets op downwardly through the respective sho ders, the-outlets at the dierent shoulders from the point. to the butt being the center of the pile.-

2. A lpile having form andhaving :fromA the esenmner and outer shoulders successivelyfarther from an inner and an outer" on the outer-form and flanges on the inner..

form bearing upon the inner `shoulders of the outer form, with jet passages carried by the inner form and communicating with the openings in the outer form at the shoulders. 3. A pile having a form provided vwith shoulders, and a point, with a casin consisting of a series of shells 4 flanges -which form shoulders, the said lian es of onesection terminating short of the dy of the other section so as to form 'et openings, and means for admitting the jettin iuid to the several jetting ope 4. pile ha an outer form with 1nner and outer sho ders, an inner form, said inner form having v upon the inner shoulders` of the outer form, and the outer form having independent jet passages leading to the several outer shoulders and to the point of the same, and means for projectix? jettin Huid to theseveral passages, sai inner orm being capable of being driven so that the pile may be simultaneously driven and jetted into the ground.

In testimony whereof,`I have signed my name to this specification, in the presence of two subscribing witnesses.
