APPARATUS FOR CONCRETING FILES.

To all whom it may concern:

Be it known that I, ALFRED H. DAVIS, a citizen of the United States, residing at St. Petersburg, in the State of Florida, have invented certain new and useful Improvements in Apparatus for Concreting Piles, of which the following is a specification.

This invention relates to an improved process and apparatus for casting concrete jackets around piling or other structures to protect them against the ravages of the teredo or other destructive marine worms and the like: and for the further purpose of reinforcing and strengthening old, decayed or worm eaten piling in docks, piers, bridges, or wherever piling is used.

One of the objects of this invention is to facilitate and lessen the cost of labor in forming a protectivecovering of concrete upon a submerged, or partially submerged portion of a pile or other similar support, after it has been driven into place, and particularly to enable the concrete covering to be carried down to the bottom of the pile, in its proper consistency and there permitted to set without the intermingling therewith, of the surrounding water.

A further object of this invention is to provide an annular space around the piling below the level of the tide which shall be comparatively devoid of water, and into which may be placed concrete mixed to the proper consistency, without its coming in contact with the surrounding water while it is being tamped in the mold.

Another object of my invention is to provide a receptacle or mold in which the concrete is placed, after having been mixed to the proper consistency by the addition of fresh water, as. contra-distinguished from the methods employed wherein the mixture, of cement and gravel is placed in dry form in receptacles and sunk into place, depending on the sea water to effect the chemical action and combination between the ingredients of the mixture, the advantages of which will hereinafter more fully appear.

A further object of my invention is an improved arrangement of the concrete jacket casting apparatus, whereby the said apparatus may be readily detached from the pile with its surrounding concrete Specification of Letters Patent. Patented Sept, 19 1916 Application filed August 15, 1910.

jacket, removed therefrom and placed in position on another pile ready to repeat the jacket casting process.

My said invention further relates to a process of covering each section with a coating of non-adhesive compound, which facilitates the removal of the molds after the concrete has become partially set, as well as imparting a smooth exterior surface to the concrete jacket.

My said invention further relates to an improved form of a detachable mold and reinforcing frames of novel construction and arrangement of parts herein described, and more particularly pointed out in the accompanying claims.

In order to more fully describe my said invention, reference will be had to the accompanying drawings in which:

Figure 1, represents in vertical section, a form of apparatus embodying my invention, the same being shown closed and locked ready to receive the concrete mixture: Fig.

Fig. 3, is a perspective view of sections of an inner-tube showing means for joining the two half sections and means for locking the longitudinal sections together. Fig. 4, is a perspective view, with parts broken away, of the reinforcing frame with the tubular mold in position therein. Fig. 5, is a vertical transverse section produced through the first mold section showing the taper funnel shaped bottom. Fig. 6, represents a transverse section open, showing the hinged reinforcing frame with the tubular mold in half sections. Fig. 7 is a sectional elevation taken centrally through a pile, disclosing the application of the apparatus. Fig. 8, is an enlarged view of the locking means whereby the flanged edges of the tubular mold are coupled together. Fig. 9, is a vertical transverse section produced through a section of the reinforcing frame showing its reinforced construction. Fig. 10, represents a transverse section of the reinforcing frame open, disclosing the hinge joint, and the locking latch. Fig. 11, is an enlarged view of one of the clevises by which the sections of the reinforcing frame are joined together.

Like parts are represented by similar characters of reference in the several views.

My apparatus consists of the following parts as shown in Fig. 1, all of which combine to produce a. portable mold or form around a pile or other structure, partially or wholly submerged, standing separately or in position in any structure of which they may form a part:

The supporting frame consists of a series of horizontal and perpendicular supports reinforced at their intersections by suitable metal plates properly bolted or riveted, the whole being bisected perpendicularly, provided with hinges at one side and an extensible locking device at the opposite side, which provides for securing the frame when the same is being adjusted or lowered into position, and unlocking and removing the same entirely by operations conducted from above the surface of water, thus eliminating the necessity of divers or submarine apparatus. By my improved process and apparatus herein described I make it possible to perform all of the operations necessary to properly concrete-jacket a pile or other support, at a point above the level of the tide.

Referring to the accompanying drawings, 1 represents a section of the inner tube; 2 represents a. section of the tubular mold form; 3 represents a section of reinforcing and supporting frame.

For the purposes of forming a concrete jacket around a. pile I provide one or more j acket-forming units, each of which is comprised in the case shown, of an inner tube immediately surrounding the pile or object to be concrete-jacketed: of a tubular mold section surrounding the inner tube and adapted to receive and contain the concrete; and of a reinforcing and supporting frame adapted to clasp around the tubular mold section for supporting and reinforcing the same during the operation of forming the concrete jacket. The sectional inner tube consists of two half sections by means of which each section is bisected vertically and placed around the pile. The contiguous vertical edges of the two half sections are provided with a tongue and groove joint, and for the purpose of making this joint watertight, I place in the groove of the joint a layer vof suitable compressible packing, such as oakum or other material, well known in the art and used for making joints water tight. lVhen the two halves of a section of inner tube have been placed in posi tion around a pile, I provide for joining the next section thereto by telescoping the intersecting joints or divisions of one section with the section below, and to provide means for securely holding the sections together, for the purpose hereinafter explained 33 provide a hasp and staple 4,

shown in Fig. 3. By this means it is possible to construct around a standing pile or other similar structure a tube of any desired length, water tight, and detachable. Around this inner tube is placed the tubular mold section 2, consisting of two half sections bisected vertically as shown in Fig. 5. For the purpose of providing a water-tight joint, the contiguous edges of the tubular mold form are made with extended flanges 5, between which are placed suitable gaskets 6, designed to be compressed by methods hereinafter described, into making a water tight seam in the joint between the two halves of the tubular mold sections.

For supporting the tubular mold sections I provide a. suitable cage frame 3, which also serves to reinforce the tubular mold, into which the concrete is placed, as shown in Figs. 1, at, 7 and 9, wherein, 7 represents angle irons, shown riveted to annular shaped hoops 8, placed at suitable intervals. At the intersections of the angle irons 7, and the annular hoops 8, are placed reinforcing plates 9. The annular shaped hoops 8, are provided with a. knuckle joint 10, upon which the supporting frame as assembled, opens to receive into and to be clasped around the tubular mold 2. At the intersecting edges of the annular shaped hoops 8, directly opposite to the knuckle joint 10, are provided locking means for latching the two bisected halves, consisting, on the one intersecting edge of latch 11, which engages the latch bar 12. which is slidably mounted at the opposite intersecting edge of the supporting frame, so that when the supporting frame is closed around the tubular mold, the protruding end 13, of the latch 11. passes through a slot in the latch bar 12, and by an upward movement of the latch bar, it lockingly engages the latch 11.

In the construction of the supporting frame, the angle irons 7 are placed in pairs as shown in Fig. 4, and are so placed in relation to each other, that the inwardly extending angles are so spaced apart, sufliciently to admit of the flanged lips 5, of the tubular mold section to be placed between the inwardly extended faces of the angle irons, and thereby securely gripping the flanged lips 5, in the closing operation of the supporting frame around the tubular mold. For the purpose of gripping these flanged lips to a greater degree, and thus insuring a water tight joint, I provide setscrews 14, tapped through one of the inwardly extended faces of the angle irons at suitable intervals, and by means of setting up these screws I am enabled to compress the gaskets 6, placed between flanged lips 5, thereby making the intersecting joints of the tubular mold sections water tight. The angle irons thus provided with compressing means and which are adapted to engage the flanged lips of the tubular mold are placed at the bisecting line of the supporting frame. For the further purpose of reinforcing the tubular mold, I place similar angle irons 7 at ninety degree intervals from those used for compressing the flanged lips 5, above referred to, which are arranged to engage an angle iron 15, shown on Figs. 2 and 4, which is securely bolted to the tubular mold section.

For the purpose of supporting the tubular mold section, I provide angle hooks 16, securely riveted to the tubular mold 2, at the upper and lower extremities thereof, and arranged to rest on the annular shaped hoops 8, of the supporting frame.

For the purpose of handling the supporting frame and swinging the same into position around the pile or other structure above to be cement jacketed I provide hooks 17 securely attached to the supporting frame. To hooks 17, are attached suitable chains or other supporting devices leading upward to the superstructure above the piling from which the apparatus is supported and lowered.

In Fig. 1, is shown the first or lower section of a supporting frame, the upper terminal of which section ends at the annular shaped hoop 8, above the supporting hooks 17. Above this annular shaped hoop is shown the beginning of another section of the supporting frame, and is shown intersected and locked to the lower section by the clevises 18, which are bolted at their upper ends to the annular hoop of the en gaging section, and are arranged to slip over the upper annular hoop of the lower section, and are locked by the bolt 19, pass ing therethrough as shown in an enlarged detailed view in Fig. 11.

For providing a suitable detachable joint for the latch bar 12, at intersections of the supporting frames, I provide an oil set joint for bringing the two sections of the latch bar in proper alinement and couple the same with a bolt 20.

In providing a suitable tubular mold section that can be placed around a standing pile I arrange for each section of the tubular mold form to be made in two half sections divided vertically the lower extremities of the first or anchor section being eontracted or reduced to funnel shape at its lower end. To provide a suitable means for making the intersecting edges of the two half sections water tight, I provide outwardly extending flanges through which I have provided suitable apertures 21, in the one half section, adapted to engage the protruding studs 22, placed in the other half section, so that when the tubular mold form is closed, the studs 22, pass through the appertures 21, and the cotter pins 23, are

inner side of the tubular mold sections at line 24, Fig. 5, arranged to telescope into the next lower section to a depth of line 25, shown in Fig. 5. This lining or apron may be made of any suitable material preferably of heavy water proof canvas or other fabric, designed to close in against the inner surface of the tubular section next below by the compressing force of the weight of the concrete mixture. For the purpose of further uniting and maintaining the superposed sections of the tubular mold casing in alinement, I provide a hasp 26, shown in Fig. 7, on the one section, adapted to engage a staple 27, on the other section, through which is inserted a suitable cotter pin. By this means the tubular casing sections are held together, and may be supported from the superstructure by suitable chains or other means, attached to the staples 27 shown in Fig. 7.

I do not limit myself to the specific form or proportionate size of tubular mold or other parts of the apparatus shown in the accompanying drawings as various sizes of molds may be used in the same supporting frame by means of adjusting the extensions therefrom, consisting of the flanges 5, and angle irons 15, and the supporting hooks 16,

to properly engage the supporting frame as herein described.

Having thus described the various parts of my apparatus in detail, the application of the same is as follows: When a concrete covering is about to be placed around a pile or other support .and without removing the.

planking of the dock or superstructure, upon which the work is to be done, the reinforcing and supporting frame is opened and placed in a horizontal position as shown in Fig. 9. Into this supporting frame is placed the tubular mold section shown in Fig. 5, which has been selected as of the proper diameter suflicient to give the required thickness of the concrete jacket for the particular pile it is to be applied to. To the inner sur face of the tubular mold section, I apply a non-adhesive mixture composed of red lead and common brown soap, which facilitates severing the tubular mold sections, from the concrete jacket after it has received its initial set, and also imparts a smoothness to the exterior surface of the concrete jackets. The

tubular mold sections are held in proper place in the frame by the supporting hooks 16, engaging the top and bottom hoops of the supporting frame. The angle irons 15, are also brought into engagement with the slot provided for in the space between the angle irons 7 7 receiving a bearing therein against the supporting frame as shown in Fig. 4. The supporting frame, together with the tubular mold forms therein is then closed together and properly latched. In this form it is supported from any cross timber or part of the superstructure by means of chains or other suitable supports, depending therefrom, attached to the hooks 17. The frame in its suspended position, together with the tubular mold form therein is then opened and swung into position around the pile above the water line, and the supporting frame is then closed and latched, and the cotter pins 23, are slipped through the holes into studs 22, thus fastening the edges of the half sections of the tubular mold casing. The set screws for compressing the gaskets 6, are then properly set up making the joints water tight. I then place th two halves of a section of the inner tube around the pile, allowing the same to slip down over the pile until the lower edge of the inner tube engages the funnel shaped bottom of the tubular mold section as shown in the dotted lines in Fig. 1, provision being made for placing a gasket on the lower end of the inner tube, where it engages in contact with the funnel shaped end of the tubular mold casing, the weight of the inner tube creating a suflicient bearing upon the gasket to make a water tight joint between the inner tube and the funnel shaped sides of the tubular mold casing. I then place in the annular space formed by the inner tube, and the tubular mold casing, a proper quantity of broken stone or gravel to make a proper foundation upon which the first application of concrete is placed. The annular space between the inner tube and the tubular mold casing. is then filled from above the water line with a concrete mixture of proper consistency. The supporting frame with the inner tube and the tubular mold casing resting therein, is then lowered until the top of th mold casing is a few inches above the water line. I't-hen place another section of the inner tube around the pile with a telescopic joint connecting the same with the like section already in place. I then repeat the process of placing another section of the tubular mold form into another section of the supporting frame and clasping the same around the pile, lowering the supporting frame section until the clevises 18, engage the uppermost annular shaped hoop 8, of the section of the supporting frame already in place. at the same time permitting the inner lining or fabric attached to the lower edge of the tubular mold section, to telescope inside of the lower mold section already in place. I then attach and fasten the .An application of cement or concrete mixture is then applied to the annular space until by such application the concrete has arisen to a point above the fabric apron and properly compressing the same against the inner sides of the next section of the tubular mold form below, thus making a water tight joint between the two mold sections so jointed as aforesaid. The whole apparatus is then again lowered and the process of applying the mold section is repeated and the concrete is continued until the lower or anchor section composing the funnel shaped tubing, reaches the bottom and is embedded sufficiently into the mud or gravel into which the pile is driven to shut off any sea water getting in from below, after which the con creting may be continued to any desired point above the water line. After the required height of the concrete jacket has been provided, the inner tube is immediately withdrawn, allowing the concrete in its plastic condition to settle around the pile without altering to any appreciable extent its proper consistency, and forcing in its settling operation, any water that may have existed in the space between the inner tube and the pile, upwardly and out through and over the top of the concrete.

Asthe inner tube is withdrawn, and the concrete settles and fills up any depressions or worm eaten cavities in the pile, sufficient concrete mixture is added at the top to always keep the level of the concrete above the water line as the tube is being withdrawn, thus providing against any disintegration of the concrete mixture. After the concrete mixture thus applied has established its initial set the reinforcing and supporting frame 3, may be removed, the tubular mold form 2, being left in position until such time as the concrete thus formed around the pile has attained sufficient age and hardiness to resist the action of the water in agitation caused by tides, currents, and undertow. After this state has been reached, the cotter pins 23 are withdrawn by suitable chains connected therewith extending upward to a point above the water line. To provide for the drawing of one of these cotter pins at a time and thus drawing the various pins in sem'atim, I arrange my draw chains connected to the cotter pins in such manner that there is a little slack chain between the fastening of the chain to the one pin and the fastening of the chain to the pin next below, so that in drawing the uppermost pin no tension is put on the next succeeding pin below, until sufficient movement of the chains has disengaged each upper pin before the drawing of the pin next below commences.

The apparatus herein described may be used in forming concrete covering other than the form which I herein show and the apparatus embodying my invention may be used for concrete coverings to other than piling or analogous marine structures and I do not desire to limit my invention in all cases to the formation of cylinders of concrete around standing piling or the like, since my apparatus may be adapted to cast jackets of other shapes and on other structures without departing from my said invention.
