EDWIN THACHER, OF NEW YORK, N. Y.
COMPOSITE PILE.
SPECIFICATION forming part of Letters Patent No. 691 ,418, dated January 21, 1902.
Application filed June 24, 1901.
To all whom it may concern:
Be it known that I, EDWIN THACHER, a citizen of the United States, residing in the borough of Manhattan, in the city of New York, county and State of New York, have invented a new and useful Improvement-in Composite Piles, of which the following is a specification.
My invention relates to piles for wharves and the like; and it has for its object the production of a pile which may besafely used in tropical waters without danger of destruction by the teredo and which at the same time employs wood in the places where it may be profitably used and is not so expensive as concrete steel construction, sometimes used under such circumstances.
In brief, my invention consists of a composite pile having an upper portion of concrete suitably strengthened by metallic elements and a lower portion of wood, the two parts being spliced together by suitable means, as will be presently described.
In the drawings, Figure 1 is a side elevation of my composite pile provided with a cap. Fig. 2 is a top plan view thereof, show ing the head of the pile in dotted outline; and Fig. 3 is a sectional view on the plane of the line 3 3 in Fig. 1.
In the drawings, a is the upper part of the body of the pile, which is composed of concrete and which may be molded to shape in any suitable manner well known to engineers. Embedded within the concrete are a plurality of longitudinal metallic bars I) 17, extending through or nearly through this part of the pile, and near the head of the pile is similarly embedded a plurality of shorter supplementary bars I) I), designed to strengthen the head when the pile is being driven into place. A metallic ring 0 is molded in contact with the lower portion of this part of the pile and is practically made integral therewith. There is similarly cast integral with it a bolt d, which projects below the upper portion of the pile.
The lower part of the pile is composed of a wooden body w, made like the lower part of any ordinary wooden pile and not difiering Serial No. 65,731. (No model.)
from it in any particular respect, except that its upper portion is turned off so as to fit into the ring 0 and is bored out so as to receive the end of the bolt (1. Dowels, as e e e 6, passing through apertures in the ring 0 and into both the concrete and wooden portion of the pile, serve to more firmly lock or splicethem together.
The head of the upper portion of the pile a is slightly less in diameter than the rest of the concrete portion of the pile and is encircled by a metallic ring f, which prevents this portion from spreading when subjected to the shock of being driven.
Z is a cap of any suitable material, adapted to fit over the head and a certain portion of the body of the pile after the same is in place and is used for connecting the heads of piles together when employed for trestlework, floors, or the like.
A ring-bolt d maybe cast integral with the upper portion of the pile and will be found useful in withdrawing it, if necessary, or in connecting a number of piles together.
What I claim as new is- 1. A composite pile having an upper portion of concrete in which are embedded a plu rality of longitudinal metallic bars, a lower portion of wood and means for splicing the two parts together.
2. A composite pile having an upper portion of concrete in which are embedded a plurality of longitudinal bars and a plurality of shortersupplementary bars near the head and having a lower portion of wood and suitable means for splicing the two parts together.
3. A composite pile having an upper portion of concrete in which are embedded a plurality of longitudinal bars and a lower portion of wood, the two bars spliced together by means of a ring encircling both parts and dowels or pins connecting the said ring to both parts.
Witness my hand this 22d day of June,190l, in the presence of two subscribing witnesses.
