PILE-CORE.'

Tol alllwhlom, -it may concern.' y

Be it knownthat I, ALFRED A. RAYMOND, a citizen of the United States, residing at Chicago, in the county of Cook and State of,

Illinois, have invented certain new and useful Improvements in Pile-Cores, of which the following is a specification.

My invention has relation to cores employed in the process of making concrete piles as practiced in accordance with my Letters Patent of the United States ,N o. 589,026, issued to meon August 31 1897; and thev object thereof is to. provide an expandible and contractible core which shall be efficient and reliable in operation for the purposes intended.

The features of advantage and utility of my improved pile-'core will be apparent'i'rom the description hereinafter given.

` In the drawings, Figure lis a longitudinal section of my pile-core, taken inthe line 1 1 of Fig. 2; Fig. 2 a cross-section on the line 2 2 of- Fig. 1; Fig. 3 a cross-section on line 3 3 of Fig. 1, -and Fig. 4 atop plan view of the core.

The process of making or forming concrete piles, to Which'this invention relates, is-fully explained in my patent aforesaid, No. 589,026, as -Well as in a subse uent patent No. 700,707, issued to me'on ay 20, 1902, and

ing of the details of such process. It will suffice to sayin the present instance vthat my process consists, in general terms, in sinking or driving into the ground or other place an outer shell by means of a core which, after -filled with concrete or the like'.

such shell is sunk or driven to the required or desired depth, is withdrawn, leaving in-.the ground the hollow shell, which is thereupon The result Of the process is th `e`formation of a concrete pile corresponding with" the shell. My present I invention relates wholly to the' core which is thusemployed for sinking the shell int-'o the ground., I

My present pile-core belongs to thesame type and character of core as that described and claimed in a prior application filed by me on september 3, 1902, Serial N o. 121,936,`

inasmuch as the same comprisesa plurality 4of'outer sections surrounding an inner section or core proper, and such present coreis intended and designed as an Improvement upon the core of that application.

Referring `particularly to Fig. 1 of the drawings, my present improvedV pile-core comprisesan inner section 1 and a series or plurality of outer substantially surrounding sections 2, which in the present instance are' three in number, although such number may, if desired, be increased, ,as found desirable or expedient. The inner section or core proper as herein shown 'is built up from a series of pipes or vtubes connected together by meansv of castings 3 or the like Vconstituting pipecouplings and also wedges for expanding the outer sections, as hereinafter explained. These pipes decreasein diameter from the top to the lower end of the pile-core, so that this inner section maybe said to taper in general -correspondencewith the taper or inclination of thelouter sections.` The uppermost pipeis connectedptoa head 4, and in the present instance the latter screws upon suchpipe. s This head has a iianged top forming a recess 5,Within which the upper these Wedge-surfaces 7, W ich incline inwardly and downwardly (reversely to the wedge-surfaces 6) are formed on segmental plates 8, which are secured to the Outer sections 2 suitable manner, as by rivets 9.

The gter sections 2 of the core are contheret in the followingmanner: Referring more particularly to Fig. 3, the inner section has sets ofbearing-lugs 10, there being three sets or pairs corresponding with the outer sections 2 in their numberq'. Three yokes 11 are 'pivoted at their ends to their respective bearing-lugs. The stems -12 of these yokes are pivoted on their respective bearingins 13, which pass through and are secure tothe ends of the outer sections 2 are receivech along its length. In the 'resent instancel nected to the inner section 1 by hing'ing Patented reb.26,19o7.

segmental plates 8.and outer sections 2 ofthe 'I' corev in" the manner vclearly indicated in Fig. 3. These bearing lugs and yokes are slightly distanced from each other-that is, they are.

' not arranged on the same'horizontal planeso as not to interfere with-each other in their movements. When in actual practice the inner section is raised slightly after the er.- gaging parts hereinafter described are unlocked, such inner section will move somewhat relatively to the outer sections, which, because of their hinged connections, will contra-ct or collapse inwardly upon the inner sec-- tion as the latter is further raised.

' xo As indicated in Figs. 1 and 2, the outer coresections are hinged tothe head 4 in suitable manner, and, as shown, such head has three side recesses, so that the head in cross-section therethrough is triangular., as seen in Fig. 2. i5 Links 14, pivoted at their outer ends to pins 15, secured to the outer core-sections 2, and at their inner ends to pins 16, securedto the head 4, constitute the connecting and hinging medium between the head and outer coresections. The pins 16 bear in lugs 17, projecting from the recesses of the head, while the pins bear in openings through the sections 2 and plates 17 riveted thereto.

To lock the core-sections in expanded con- :5 dition, locking-dogs 18 are ivoted on the 1prins 16 and inclined upwardy so that their ee ends will engage notched lugs 19, projecting inward from the plates 17. Unlocking latches or levers 20 are pivoted in side openings in the outer sections,'with their inner ends arranged to bear against the lockingdogs and free the latter from their engagement with the lugs 19. The lowermost pipe of the inner section of the core is provided with a casting or hollow end piece 21, having awedge-surface 22 entering the hollow end of a point or tip 23, and bearing against the inclined or Wedge surface 24 of such tip. Thistip has a central openlng 25 constituting'a jet-orifice to be used in case'it is desired toem ploy the j etting process alone for sinking the shelland core instead of driving the same or in connection with and 1n assistance to driving or pressure .applied from above.

Arranged centrally within and concentric with the upper or larger end ofthe inner section 1 of the pile-core is a jet-pipe 26, coni nectedwith the head 4. and communicating 5o' with the passage 27 therein leading from a source of fluid sup ly, generally water, although air may be tlie j etting fluid employed in some instances. The lower end of'the jetpipe 26 extends downwardly through the inner core-section and is attached thereto at the point 28- where the bore becomes substantially of the same diameter as that of such jet-pipe. Below this'point of attachment the olloW inner core-section itself serves as the jet conduit or passage, which finally communicates with the jet-orifice 25 in the tip.

As hereinbefore stated,the wedge-surfaces onI the pipe-couplings cooperate with the complementary wedge-surfaces 7 on the outer connections and serve as expanders, inasl with the yokes; substantially asdescribed.

section and communicating with the jet-oriitself; substantially as described.

much as when the inner core-section is forced downwardly its Wedge-surfaces vbearing outwardly upon the other wedge-surfaces will expand the outer core-sections to proper posit-ion within the shell. (Not shown.)

Although I have described more or less precise forms andk details ofconstruction, I do not intend to be understood as limiting myself thereto, as 1 contemplate changes in form, proportion of parts, and the substitution ot equivalents, as circumstances may suggest or render expedient, without departing from my invention and claims.
