DEVICE FOR PROTECTING PILES, &o.

Application filed September 7.1904. Serial No. 223,645.

To @ZZ tch/0m, it nca/y concern: u

Be it known that I, PHILIP AYLETT, a citizen of the United States, residing at Portsmouth, in the county of Norfolk and State of Virginia, have invented a new and useful Device for Protecting Piles and Similar Submerged Woodwork, of which the following is a specification.

The invention relates to improvements in devices for protecting piles and similar submerged woodwork.

The object of the present invention is to improve the construction of devices for protecting iles and similar submerged woodwork emp oyed in the construction of wharves, bridges, abutments, and analogous structures and to provide a simple, inexpensive, and efficient device adapted to be applied to and removed from a pile or the like without affecting the structure.

A further object of the invention is to provide a pile-protector which may be either applied while a wharf, bridge, or other structure is being constructed or after the same has been completed and which will be capable of effectually protecting such submerged woodwork from the ravages of the ship-worm and other marine insects.

Another object of the invention is to provide a pile-protector which will always rest upon the bottom of a stream or other body of water to protect a pile from the mud-line to a point above the surface of the water and which will be automatically adjustable and gradually descend as the bottom of such stream or other body of water changes through scour or other cause.

The invention also has for its object to provide a pile-protector which may be manipulated from the top when it is desired to place it in position -or remove it or increase its length.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts,

' hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the in- .vention.

l protect a pile from the mud -line to a point Patented Aug. 29, 1905.

partly in section, of a structure provided at the submerged portions of its woodwork with pile-protectors constructed in accordance with this invention. l Fig. 2 is an enlarged sectional view of two of the pipes of the adj ustable tubularpile-casing, Fig. 3 is a plan view of the same, the .pile being in section. Fig. 4 is a detail sectional view illustrating a slight modification of the means for interlocking the pipes together. Fig. 5 is a longitudinal sectional view illustrating another modification of the invention and showing two pipes connected by and interlocked with a sectional collar or coupling. Fig. 6 is a horizontal sectional view of the same. Fig. 7 is a detail vertical sectional view showing another form of collar or coupling.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates al tubular pile casing composed of one or more pipes 2, of terra-cotta or any other suitable material which will be unaffected by sea-water. The pipes of the tubular casing are interlocked at their ends, as hereinafter described, and a casing may thereby be constructed of any desired length to suit the depth of water and to allow for any desired change in the bottom of a stream or other body of water. The length of the tubular pile-casing may be increased from time to time, as hereinafter explained, to

above the surface of the water, and the internal diameter of the casing is in excess of the diameter of the pile to provide an intervening space, which receives a packing 3 of loose material, such as sand, cinders, gravel, or any other suitable material. A mixture of sand and gravel will be found exceedingly effective, and this packing will permit the `pile-casing to descend as the mud-line is lowered by the washing away of the bottom. Also the packing or 'filling of loose material will not interfere with the removal of the tubular pile casing, which may be readily lifted from the top, thereby obviating the necessity of introducing a hook beneath the lower end of the pile-casing, which operation is necessary when the pipes are not connected, as hereinafter explained. When removing the pile-casing, the packing or filling can be conveniently washed away by the use of a small hand-pump, if desired.

Each of the pipes 2 of the tubular casing is divided longitudinally and is composed of a plurality of sections 4, whichv are connected at their contiguous longitudinal Aedges by scarf lock-joints 5, having longitudinal keys 6, of wood or other suitable material. These keys, which extend from the top to the bottom of the body portions of the sections 4, are wedge-shaped, being tapered. upwardly to enable them when removing the pile-easing to be readily loosened or driven out by blows upon their upper ends. By dividing the pipes longitudinally they may be readily placed around a pile without affecting the structure of which the pile forms a part, and the piles may be protected after such structure has been erected. The sections may be cast or molded in any desired manner, as will be readily understood, and although only two sections are illustrated in the accompanying drawings, yet it will be readily understood that the pipes may be constructed of any desirednumber ofl sections. The upper ends 7 of the pipes are enlarged to from sockets for the reception of the lower or spigot ends 8 of the contiguous sections. lhe socket ends are provided with inwardlyextending curved flanges 9, which form grooves and which are spaced apart, as clearly shown in Fig. 3. The spigot ends S are provided with outwardlyextendingv curved flanges 10, which are adapted to lit in the grooves and interlock with the inwardly-extending flanges 9. The space between the ends of the inwardly-extending flanges 9 are of a size to permit the outwardly-extending flanges to be introduced into the enlarged ends or sockets, and by ro.- tating the pipes a quarter of a revolution the flanges are interlocked by carrying the outwardly-extending flanges 10 beneath the inwardly-extending flanges 9. This partial rotation of the pipes also causes them to break joints, as indicated in Fig. 2 of the drawings. The pipes are also preferably enlarged adj acent to their spigot ends, as shown inl Fig. 2, to increase the strength of the device. The flanges or projecting portions of the ends 7 and S are provided with horizontal engaging faces, as illustrated in Fig. 2; but the pipes may be detachably interlocked by bevel or Wedge shaped engaging portions 11 and 12, as illustrated in Fig. 4 of the drawings.

In Figs. 5 and 6 of the drawings is illustrated another modification of the invention, in which the pipes 13 are detachably connected by means of a sectional collar or coupling 14. The sections 'of the collar or coupling are connected byscarf lock-joints 15, having removablytapered or Wedgeshaped keys 16, of wood or other suitable material. 4, inclusive, of the drawings the ends ofthe keys abut against the ends of the adjacentpipes, and the said keys are wholly concealed within the tubular casing and are thereby ln the form illustrated in Figs. 1 toprotected; but in the form shown in Figs. 5 and 6 the keys may be coated or otherwise treated to protect them. The sectional collar or coupling 14 is provided with opposite grooves 17 for the reception of annular flanges 1S of the pipes 13. The upper and lower ends19 and 20 of the pipes may be beveled, as shown in Fig. 5, or square shoulders or seats may be employed, as shown at 21 in Fig. 7 of the drawings.

The packing which excludes the water from the casing may be conveniently introduced into the same Aby means of a flexibler tube or pipe 22, designed to be carried by a car 23, as shown in Fig. 1. The flexible pipe is provided at its upper end with a hopper or funnel 24, land it has a tapering discharge nozzle or end 25, which is adapted to extend into a sectional funnel 26. The sectional funnel 26 is adapted to be placed around a pile and fitted within the upper end of the pile-casing, as shown in Fig. l.

The pile-protector, which may be applied to the piles of a structure after the same has been completed, as well as while the structure is being erected, is manipulated from the top by placing the pipe-sections around a pile and interlocking or connecting the pipes, which are successively lowered until a pilecasing is constructed of a length to extend from the mud-line to a, point above the surface of the water. The bottom pipe is partially embedded in the mud vthrough the weight of the casing, and the latter is adapted to drop or descend automatically as the bottom is Washed away. By this operation the pile-casing is adapted to automatically maintain its position upon the bottom of a stream or other body of water, andthe submerged woodwork is elfectually protected from the mud-line to a point above the surface. TheA pile-casing may be removed without affecting the structure, as it is lifted from the top, the sections being successively removed. When the pile-casingis removed, it may be used' again, as it is not affected by sea-water or yby ship-worms or other marine insects.

The sections may be made of any desired length, and when a pile-casing is applied to a crooked pile the sections by being made in short lengths and by being constructed to allow a limited play at the joints may be readily arranged to fit such crooked pile.

Also by protecting the pile only from the mud-line to a point above the surface of the water apile-protector of a minimum length is provided, and the cost is also reduced to a minimum and. is ymuch less than where an entire pile is protected.
