INCASED CONCRETE FILING.

Specicatlon of Letters Patent.

Patented July 29, 19.13.

.l Application led February 25, 1913. Serial No. 750,498.

.ment at their abutting ends by internal sleeves, are driven or sunken into the ground, a cluster of iron or steel reinforcing rods placed therein, and the pile casing then filled with cement or concrete so as to unite the casing sections, alining sleeves and reinforcing rods together and to the concrete l zo lling to make the complete pile.

My invention consists mainly in makin the internal alining sleeves elongated, wit guiding and holdin tubes or semi-tubes, for the reinforcing ro s, of a length equal to that of the respective sleeve or suicient to allow for' considerable variations in the length of the sections of the reinforcing rods, which are made in lengths substantially equal to the respective tubular sections of the casing, so that when the lowest casing section is sunken into the ground, and the lowest sections of the reinforcing rods and the alining sleeve 'placed thereon, the upper ends of the rod sections will all rest within the respective guiding tubes of the alining sleeve in spite of variations in the lengths of rods. Likewise when the neXt casing section is driven home and the corresponding rod sections are placed therein with their lower ends in the guiding tubes of the first alining sleeve, the upper ends of said rods will also all be within the guiding tubes of the next alining sleeve, all

as will be hereafter more fully described.

In order that my invention may be fully understood I shall first describe in detail the mode in which I carry m invention into practice and then distincty claim the invention.

Reference is to be had to the accompanying drawings forming part of this specification,. in which like parts are designated byA the same numbers -in all the figures. y

Figure 1 is a sectional side elevatlon of a reinforced-incased concrete pipe embodying my invention. Fig. 2 is an enlarged plan view of the combined alining sleeve and rod holder of the same. Fig. 8 is a side elevation partly 1n section of the combined alining sleeve and rod holder. I In the drawings 10, 11 are the tubular metalllc sections, formlng the casing of the pile; -12'is the driving cap preferably used for recelving the blows of the pile driver; 13 is the driving shoe formed with a neck le to lit tightly within the lower end of the plle casing; 15 1s one of the metallic internal sleeves for holding the abutting ends of the caslng sections in alinement, and 16 are the reinforcing rods, placed and held vertically apart within the pile casing.

The concrete or cement filling is poured mto the pileA casing, after the casing is driven home and the reinforcing rods are placed therein, to bind and unite the casing sections, alining sleeves, driving shoe, if used, aud reinforcing rods together to form the complete pile.

Eciently, conveniently and economically to gulde and hold the vertical reinforcing rods 16 in position apart, I preferably cast on the interior side wall of the hollow driving shoe 13, when one is used, inwardly and radially projecting-bosses 18 spaced peripherally around the shoe as the reinforcing rods 16 are to be spaced, and formed in their upper ends with vertical .sockets 19 to receive loosely the lowerends of the several reinforcing rods 16, after the pile casin is driven home. To the same end, I preferaly 'cast the alining sleeve 15 with inwardly and` radially projecting bosses 20 formed with vertical guiding tubes or semi-tubes 21, spaced peripherally around the sleeve 15 as the vertical reinforcing rods 16 are to be spaced, to receive and hold said rods in their proper-relative positions within the casing. l

The vertical reinforcing rods 16 are made in sections substantially equal in length to the respective casin sections, so that the ends of the rod sections will terminate and rest in the guiding tubes 21 of the respective alining sleves 15; but as the rod sections will in practice vary considerably from this length, it is essential that the tubes 21 be elongated the full length of the elongated alining sleeve 15 with which they are formed or at least a substantial part of said length, so that, irrespective of said variations in length of the rod sections, their ends will always extend into and be confined in the elongated guiding tubes 21.

It is evident that in sinking the casing sections, and introducing therein the alining sleeves 15, the rod guiding tubes 21 therein must be placed in axial alinelnent with the rod sockets 19 in the driving shoe and with the rod guiding tubes 2 1 in the other alining sleeves.

To hold the alining sleeve 15 in position in the abutting end portions of the casing sections 10, 11, I may use any suitable means, such as indentations 22 in the casing sections above and below the alining sleeve 15, as shown in Fig. 4, and claimed in my prior United States Letters Patent, dated May 31, 1910, No. 959,546. In Figs. 1, 2 and 3, however, I have shown the alining sleeve 15 cast with an integral peripheral ring 23 around its middle, by preference slightly dovetail in section, to come betiveen and register exteriorly with the abutting ends of the casing sections 10, 11, to receive t-lie end 'thrust thereof and serve as a stop to hold the sleeve against endwise displacement Within the abutting ends of the sections 10 and 11, as shown in Fig. 1. In this instance, I continue the medial ring 23 inward to the interior of the rod guiding tubes 21, to serve as bearings for the respective ends of the reinforcing rods. l

It will be evident that, When the diaphragm portion 2li extending across the guiding tubes 21 is omitted, then the lower end of each rod section 1G Will rest,Wit-hin the respective guiding tube 21, upon the upper end of the rod section below it, and the described elongation of the guiding tubes will insure the meeting of the superposed rod sections Within the guiding tube in spite of the variations in the lengths of the rod sections.

The integral formation of the alming sleeve with the lnterior rod-holding bosses forms an extremely simple, economical, effective and convenient means for guiding and holding the reinforcing rods in their allot-ted positions, and the rod holding bosses in addition cooperate effectively with the concrete filling, tubular sections, sleeves and reinforcing rods to bind the Whole coinposite pile together and form a pile of great strength and durability.

Having thus described my invention and the mode in which I carry.the same into practice, I claim:

1. In reinforced incased concrete piling, the combination Wit-h the tubular metallic casing sections, of an elongated alining sleeve fitted Within the abutting ends of the casing sections and formed interiorly With elongated longitudinal guiding tubes for reinforcing rods to confine the meeting ends of rod sections of varying length, reinforcing rod sections of a length substantially equal to that of the corresponding casing sections having their adjacent ends confined Within the respective guiding tubes and a filling of concrete to unite the Whole together.

2. The elongated alining sleeve for joining the abutting ends of the metallic casing sections together formed interiorly with elongated longitudinal guiding and conning tubes for the varying meeting ends of vertical reinforcing rods, substantially as described.
