UNITED STATES PATENT OFFICE.

JOHN KENNY, OF NEW YORK, N. Y., ASSIGNOR 'IO JOHN SIMMONS COMPANY, A CORPORATION OF NEW YORK. v

INCASED `(JONCRETE PILING.

Specification of Letters latentl Application filed July 10, 1913.

To all whom t may concern:

Be it known that I, JOHN KENNY, a citizen of the United States, residing in Brooklyn, county of Kings, city and State of New York, have invented a new, and. useful Improvement-in Incased-Concrete Filing, (Case B,) of Jwhich the following is a specification.

My invention relates to certain improvements inthe construction of the sleeves used, in the construction of reinforced concrete piling, to hold the superposed tubular metallic casing sections in alinement and to guide and hold the internal metallic reinforcing rods in position. One example of such a combination alining land rod-holding sleeve especially adapted for sectional reinforcing rods is shown and described in 'my prior application for patent filed February 25, 1913, Serial Number 50,498, and allowed June 6, 1913.

Among the objects of my present improvement are to lighten the weight of and save metal in combination sleeves of thisgeneral description, without impairing their efficiency, and to provide more space between the internal rod-holding tubes for admitting the washing out pipe and for lthe upward passage through the casing of the earth ejected by the compressed air or water used in washing out.

To these and other ends my invention consists first, in forming short internal rodholding tubes preferably at one or both ends of the alining sleeve and, secondly, in removing the innermost segments of said rodholding tubes, substantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming part of this specification in .which like parts are designated by the same numbers throughout.

Figure 1 isa longitudinal sectional elevatio-n of a reinforced incased concrete pile embodying my invention. Fig. 2 is an enlarged sectional view of the combination alining and rod-holding sleeve of the same. Fig. 3 is a plan view of the said `Vcombination sleeve.

Referring to the drawings,10, 11, are two tubular metallic sections. forming ,the casing of the pile, 12 is a drivin cap preferably used for receiving the bl ws of' the pile driver, 15 is one of the elongated metallic internal sleeves for holding the abutting ends of the casing sections in alinement, and 1 6 are reinforcing rods placed and held vertically apart within the pile casing. The concrete or cement filling is poured into the pile casing, after the casing is driven ho-me and the reinforcing rods are placed therein, to bind and unite the casing sections, alining sleeves and reinforcing rods together to form the complete pile. The alining sleeve 15 is in this example of my invention held in position in the abutting end portions of the casing-sections by indentations 19 formed in the casing sections above and below the alining sleeve, but may be stopped or positively locked in such position in any other suitable manner.

In my prior application for patent Serial No. 750,498, before referred to, I have shown and described the alining sleeve formed with internal longitudinal tubes for guiding and holding the vertical reinforcing rods in their pro-per positions in the casing, the construction shown therein being particularly adapted for sectional reinforcing rods. When the continuous or one-piece reinforcing rods 16 are used, as shown in Fig. 1, I save weight and metal, and at the same time leave more space for the ejection of earth, stone and rubbish around the compressed air or water pipe used in .washing out, by casting sets of short interior rod-holding 'tubes 17, prefer` ably at each end of the sleeve 15, and omitting the innermost segments of said tubes so as to form segmental openings 18 toward the ends of the casing. By these short inwardly7 opening tubes 17 the reinforcing rods 16 are equally well guided and held in position apart from the casing wall, while at the same time, the increased space above or below the tubes 17 and the segmental openings 18 as well, leave more room around the washout pipe 20, for the outward passage of-the earth etc. around it, as indicated.

By preference, the rod-holding tubes 17, 17a, hold the reinforcing rods so far apart from the wall of the casing sections 10, 11,

that the concrete filling (not shown) will surround the reinforcing rods 16 on all sides, and will thus, as well as the completed pile, be strengthened thereby to the greatest possible extent.

I claim as my invention:

The alining'sleeve for joining'the abutting ends of the metallic casing sections together, formed interiorly with longitudinal 6 guides lfor holding vertical reinforcing rods,

said guides having segment-a1 openings t0- Ward the axis of the sleeve, substantially as In presence of- L. COCHNAR, PHILLIP WIEGAND.
