T0 @ZZ whom t 771.1025/ concer/t:

Sandusky, in the county ot' Erie and State ol' Ohio, have invented certain new and useful Improvements in Method of Protecting Piles from Marine Insects; and I do hereby declare the followingr to be a full, clear, and exact description ot' the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to an improvemen'tin protecting piles from marine insects; and it consists in the peculiar manner of covering the whole or a portion of the pile, as will be hereinafter more fully described, and pointed out in the claims.

The accompanying drawings show one method of securing,` my improved covering to a pile.

Ileretofore many diii'crent methods have been resorted to to prevent the destruction of piles by marine insects, and the experiments usually consisted in coating the piles with some adhesive subst-ance supposed to be of a nature difficult for the insects to penetrate. Sonie of these devices have succeeded in keeping` the insects from the piles, but, owing to their lbrittleness or frangibility, are easily scaled oft' by boats or floating ice coming in contact therewith, and hence they soon become useless; and the main objectof this invention is to provide a covering` for piles that will not only resist the invasion of the insects, but that will also remain intact and not liable to be scaled or broken by the rubbing of boats or Boating` ice thcreagainst. These insects require, for the destructive employment of their peculiar boring apparatus, a iirin compact sul stance on which to attach themselves, and Without such a surface is presented they cannot penetrate the Wood. In view of this fact I have devised. a manner of protecting the piles or other timbers, Amfliich consists, essentiaily, in first coatingthe Whole or a portion of the pile with a preparation ot' asphalt or other material, then Winding` a strip of canvas or other clot-h spirall7 around the portion coated with the asphalt, and securing the spiral strip to the pile. rlhis covering is then coated with a similar or any other preparation, and is covered by another strip `Wound spirally in the opposite direction around the i pile. Bc it known that I, lIiioon en .Ci-iiir, of i the pile eanbevaricd,asdcsired.

rlhe method, however, of protecting The brous covering oi the piles is protected from ahrasion While being,` secured in position and While in the Water by nailing over the same strips of boards C, either prepared to resist marine insect-s or not so prepa-red, or using for the same purpose strips of metal Wound spirally around the pile when covered. The covering need 011137 be applied to that portion of the pile or timber submerged in the Water; but it is better to have the cover extend down a slight distance into the inud.

Instead of lirst coating the pile with the asphalt, the iirst layer ot' thecovering can be lined or coated or otherwise impregnated with the asphalt or preparation thereof to cause it to adhere to the pile; or the iibrous coveri115` can be coated either before or after it is applied to the pile with asphalt or any other material that will render the covering more durable.

I would have it understood that I do not confine myself to any particular manner of securing the covering to the pile or other tiniber, but consider myself at liberty to secure the covering in any manner, and to make such other changes as fairly fall within thc spirit and scope of my invention.

Having fully described intr invention, what I claim as new, and desire to secure by Letters Patent, is

l. As' a protection i'or piles against marine insects, a covering' ot' cloth or other tibrous material secured around a pile, and Wooden or other strips scoured to the outer face of the ilexible covering for the purpose of protecting the latter against abrasion.

2. As a protection 'for piles against marine insects, a coveringL of cloth impregnated with asphalt or other similar material, and secured around the pile, and wooden or other strips secured to the covering` for the purpose of protecting the latter against abrasion.

The combination, with a pile wholly or partly coated with asphalt or other similar material, ot' a flexible covering,` secured around the pile and impregnated With asphalt or other similar material, and wooden or other strips secured against the outer face of the tlexible covering, substantially as set io'rth.
