JPR'ESERVING AND PROTECTING PILES.

SPECIIEICA'JL'ION forming part of Letters Patent No. 282,807, dated August 7, 1883.

Application filed April 4, 1883. (No model.)

To all whom it may concern Be it known that I, DAVID H. VALENTINE, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Preserving and Protecting Piles, of which the following is a full, clear, and exact description.

The object of my invention is to devise prac tical means for protecting the wooden piles of bridges, docks, and other structures from being eaten by worms and insects, and from the destroying effect of constant wetting and drying of the piles at the surface of the ground or water; and to these ends my invention consists in the peculiar construction and arrange. ment of the parts, as hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation, showing a pile having my preserving and protecting shield and outer covering applied thereto. Fig. 2.is afront elevation, showing the casing used for molding the shield around the piles 5 and Fig. 3 is a sectional plan viewof the pile, shield, and easing taken on the line 00 x of Fig. 2.

A represents a shield that is molded around the pile B after the pile has been driven into the ground, and extends from the ground or mud (or slightly below the surface thereof) up the pile, so that the upper end of the shield stands above high-water mark. Theshield is composed of Portland or any other suitable hydraulic cement, or of asphaltum concrete, and is by preference molded with the enlargement (4 at the bottom, as shown in Fig. 1, to form a suitable base to prevent the shield from settling and the shield is by preference formed at the top with the cup 1), into which a quantity of oil, asphaltum, or pitch or other suitable material may be poured to preserve the wood of the pile, and to make a waterproof joint between the shield and the pile.

In molding the shield A, I employ the sectional easing or mold O, which is composed of two sections, 0 c, that are adapted to be placed around the pile, as shown in Figs. 2 and 3, and,

- to be trussed together by the hinged sectional hoops d d, and bolts 6 e, that pass through the free bent endsfll 2' thereof, as shown clearly in Fig. 3. .The sections 0 c of the casing or mold thus placed and locked around the pile will then be lowered to the mud, and their lower ends settled slightly into the mud, forming a coffer-dam around the pile. The water in the casing (should there be any) will now be pumped out by a suitable pipe and pump, and then the mold or casing will be filled with the cement, concrete, or other material for forming the shield A. The mold or casing having been filled to the top, the cup b will be formed with a trowel, and the casing or shield willbe left in place until the cement or concrete shall have become set or sufficiently hardened to remain in place without the support of the mold, whereupon the casing will be removed, and then, if the outer covering, D, is to be used, it will be put around the shield and stitched in place. This outer covering is by preference made of strong, coarse, heavy canvas, but other strong and cheap material might be used; and the covering, before being placed around the shield, has the wide hem f formed at one end, in which is placed a quantity ofcement, concrete, stones, or other heavy material for weighting the canvas for carrying the lower end of the covering down to and holding it around the bottom of the shield A, as will be understood from Fig. 1, 'so that the shield will be thoroughly protected from the wash of the water. In this manner it will be seen that the pile is thoroughly protected and preserved, not only from the action of the water and the ravages of worms and .wood-eatin g insects, but also from the weather and. from floating ice, and hence the strength and durability of the pile is greatly increased by means of the shield A. Besides, the cost and labor of applying the shield is comparatively small,

and the shield, when applied, is durableand practical for its purpose.

It is for the sake of economy that the molds O are removed for subsequent use and the covering D substituted but where the expense is no special object it is designed to leave the molds 0 upon the shield A, which will greatly increase the efficiency of the protection; and instead of placing the canvas covering around the shield A after the mold O has been removed, it might be placed within the mold be- 2. The combination, With the shield A, mol ded upon the pile B, of the outer covering, D,

provided with the hem f, to receive weights to carry and hold the lower end of the covering down around the bottom of the shield, sub stantially as described, and for the purpose set forth.
