Patented July 4, 1933 unit! an STATES .ELH-I-U n. WATT, OFEPLAINFIELD, NEW Jnssnxnssisnon moRAmoNneoNoREnE v('90IVlIIPA-lilY, OF NEW YORK, -N. Y., A CORPO-RATION'OF NEW JERSEY V COMPOSITE PILE JOINT 'Applieation filed September 20, 1932. Serial No. 633,96 6.'
This-invention pertainsto composite piles in whicl-i' the lower Sect/101118 of wood, and
the u 3 er section is of concrete.
- l he primary -ob ect of the invention is to disclose an improved joint for interlocking the upperand lower sections to prevent their separation after driving.
In the present invention, a wedge ring is used as in Vatt and Whitne Patent N o. 1865,6237, but the ring ishere used pliedin a di'iferent manner.
Further andother objects and advantages will be apparent fromthe specification and claims, and from the accompanying drawing which illustrates what is now considered the preferred embodiment of the invention.
F ig. '1 shows the lower pile section with the 'drive head in position during the driving Fig. 2 showsthe drive head, follower, wedgea'ing and other parts in position to resume driving after the shell for the upper sectionhaslbeen placed in position.
' Fig.3 shows the joint between the sections 5 after the driving is completed and the upper section is filled with concrete."
pile section-,and12 is the drive head provided with downwardly projecting annular wedges 14 and 16, which, during the operation of driving the lower section, form annular grooves 18 and 20 in the flat top sur face of that section (Fig. 2). 7
After section 10 has been driven until its upper end approaches ground level, as
in Fig. 1, drive head 12 is removed, wedge ring 22 is placed with its lower edge in groove 18 (Fig. 2), shell 24: is placed withits upper end in groove 20, andfollower 26 surmounted by drive head'12 is lowered into position as in Fig. 2, with its lower end resting on wedge ring 22, and on shoulder 28 provided at the lower end of the shell. This shoulder is usually formed in a ring 30 of metal thicker. than the shell and welded thereto. The lower part 32 of the ring, below the shoulder, is usually conical and substantially parallel to the outer surface of wedge ring 22.
The upper end of follower 26 is provided with a head 34 having an annular recess 36 and apto "freely accommodate rings l i and 16 '1 of drive head 12. e a r lvith the pa'rts arranged as above "(le scribed, and as shown in Fig'. 2,"drivin'g is resumed. The'firstblows: onfollower26 rom wedge ring 22 into itseg'roove 18,a nd-con'e 32 into its groove'20. The ring of wood-32 is 7 forced radially :outwards by wedge ring 22 with shell 24 following down into the'hole formed by the lower section After the proper depth is reached,-the follower is with drawn and: the shell is filled withiconcrete 40 :to' form the complete composite pile, as indicatedin Fig. 3. i I
It 'isfto be under-stood that "the inveiition is not limited to the specific embodiment here Y in illustrated and described, but maybe'used' in "other ways without'de'parture "from its spirit a'sd'efined by the followings claims; In the drawing, l0 is the lower wooden i "I claim 1. '-In t'h'e method of 'forming' a-bomposite pile having a lower section of wood and a shell surmountingsaid lower section, said shell having a lower end of restricted diameter, the steps of mounting said shell on section, causing said shell to enter the flat upper end of said lower section, and filling the said shell with concrete.
3. In the method of forming a composite pile having a lower section of wood and a shell 'surrnounting said lower section, said shellfhaving a lower end of restricted di ameter, the steps of mounting said shell on said lower section whereby said restricted portlon enters an annular groove 1n the flat top of said lower section, flaring out a portion of said lower section into engagement with said restricted portion during the driving of the lower section, and then filling the shell with concrete. l
4. In the method of forming a composite pile having a fiat-topped lower section and a shell surmounting said section, the steps of mounting said shell on top of said lower section, causing said shell to enter and fill a groove in the upper end of said lower section during the driving of the lower section, and filling the said shell with concrete. 1 5. In a composite pile, a flat-topped lower section of wood, a shell surmounting said lower section and adapted for receiving concrete; to form the upper pile section, and means for locking the lower end of said shell into the flat top of said lower section.
I 6.In a composite pile, a flat-topped lower section of wood, a shell surmounting said lower section and, adapted for receiving concrete to form the upper pile section, and means comprising a wedge ring for causing the top of said lower section to engage the lower end of said shell for locking the lower end of'said shell into the fiat top of said lower section.
a 7. In a. composite pile, a fiat-topped lower section of wood, a shell surmounting said lower section and adapted for receiving concrete toform the upper pile section, said shell having a lower end of reduced diameter, and a wedge ring adapted to cooperate with said reducedlower end for locking the lower end of said shell into the flat top of said lower pile section.
'8. A composite pile comprising, in comhination, a flat-topped lower section of wood, and an upper section of concrete, said upper section beingencased by a shell, and means for locking the lower end of said shell into the fiat-top of said lower section.
9. A composite pile comprising, in com bination, a flat-topped lower section of wood, and an upper section of concrete, said upper section being encased by a shell, and means comprising a wedge ring for locking the lower end of said shell into the flattop of said lower section. V
10. The method of forming a" composite pile having a flat top lower section of wood 7 and a shell surmounting said lower section, said shell having a lower end of restricted diameter, the steps of driving said lower sec-. tion into the ground and simultaneously forming grooves in the flat top of said lower section, mounting the shell on said lower section and further driving said lower section to draw down the shell into the hole formed by the lower section and simultane ously driving the restricted lower end of the shell into one of the grooves and flaring out a portion of said lower section into engagement with said restricted portions 11. The methd of forming a composite pile having a fiat top lower section of wood and a shell surmounting said lower section,.said shell having. a lower end of restricted diameter, the steps of driving said lower section into the ground and simultaneously forming grooves in the fiat top of said lower section, mounting the shell onsaid lower 'secnature. a
