Be itknown that I, Geenen BROWN, ofthe city and county of San Francisco, State of California, have invented an Improvement for Protecting Piles; and I hereby declare the following to be a full, clear,`and exact description of the same. Y
My invention relates to an improved means for protecting piles from the ravages of marine worms and insects. lt consists of an exterior casing made of stri ps of wood or material which will resist the attacks of the insects. This casing is jointed so as to make it water-tight, and is supported at a short distance away from the body ofthe pile by blocks fixed around the pile at intervals, and the ends are nished out by solid beveled blocks which close them completely. The space within this exterior casing is filled with an adhesive or binding compound. In connection with this Iemploy an extension or fender upon such piles as are exposed to contact from vessels or exterior vabrading substances.
Referring to the accompanying drawings for a more complete explanation of myinvention, Figure 1 is a View of the pile, showing a side elevation of that portion which is incased. Fig. 2 is a transverse section taken through X X, Fig. l. Fig. 3 is a side elevation showing the fender-extension. Fig. et is a transverse section taken through Y Y of Fig. 3.
A is a pile in condition to be driven, and B B are strips made of black-heart redwood, cedar, or wood of any kind prepared so as to resist the ravages of marine insects. These strips are made of sufiicient length to reach from a point just below the mnd when the pile is driven to a pointjust at or above the highwater mark. They are made in the form of staves from three to six inches in width and from one to threeinchesin thickness, the edges being beveled to ht together nearly or quite water-tight, and so as to leave a space of onehalf inch or more between the pile and the casing, which space is to be dlled with an adhesive or protecting compound, and which will also unite the pile and the casing into a solid body. These staves are held away from the body of the pile by means of blocks C, the ins ner surfaces of which are fitted to the pile,and the outer surfaces are so formed that the inner surfaces of the staves will rest upon them.
These blocks C are jointed to the staves, so that when nailed on around the pile they form a complete circle, the outer faces of each two adjacent blocks being made dat, so that each of the stavesB will rest upon two of the blocks, the joint between the blocks extending midway of the width of `the stave, as shown more completely in Fig. 2. These blocks are secured around the pile at intervals sufficiently near together so that when the staves are nailed to them they are thoroughly secured and supported., The ends ofthe staves at the top and bottom are slightly beveled, and solid blocks ,D are fitted to the pile and also to the ends of the staves, so as to form short continuations of them, the upper and lower ends being beveled, so that the blocks when secured around the pile above the upper and lower end of the stave will form aprotection and iinish for these ends and close them up. The blocks have their ends so beveled that they form a conical shape about the pile, as shown in Figs. l and 3. When the staves and the end blocks have all been secured around the pile, the last one of the staves being left out, the space between the pile and the exterior casing is lled with the adhesive compound, after which the iinal stave is nailed in place and the pile is complete and ready for driving. vWhen the piles are exterior ones which are exposed to abrasion by vessels, I cut ont at the upper end two of the staves B for a distance'of about halfway between high and low tide and tit into the space thus cnt out an oak or other fender, E, which extentie up along that portion ofthe pile A which is above the water, and is secured to it, so that vessels or other heavy articles which may float near the wharf will not chafe or bruise the piles. Upon each side of this extension E is fitted a triangular piece, F, which is securely fastened into the angle, and thus forms a beveled side to the fender'strip. Ihe outer edges of these strips are reduced to about threeiourths of an inch in thickness and the whole is secured with composition or galvanized nails.
By this construction I am enabled to protect a valuable pile by an exterior covering which is of less value, and which will effectually prevent marine insects from having any access to the pile.
Having thus described my invention, what I that the inner faces of the staves are secured to the support by them, and an intermediate filling of adhesive or protecting material, in combination with the beveled end blocks fitting and forming the continuation ofthe staves and closing the ends thereto, substantially as zo herein described.
3. The staves jointed and supported upon the series of blocks secured to the pile so that a space is left between the pile and the stave, and the filling of adhesive or protecting mate- 25 rial between the staves and the pile, in combination with the fender or extension with the angular side piece, substantially as hereindescribed.
In witness whereof I have hereunto set my 3o hand.
