To aIZZ whom it may concern:

Be it known that we, HENRY ANbichsoN, of Oakland, Alameda county, and llUGll ELIAS, of the city and county of San lrrancisco, State of California, have invcntcdun Improvement in Pile-Covering; and we hereby declare the following to be a t'ull,cleur, and exact description of the same.

The object of our invcnlion is to provide a suitable. means t'orlhoprolection of piles from the ravages of the tcrcdo and the limnoria and other marine insects.

It; consists of a certain preparation and covering for that portion of the pile extending from the mud orboltom to a poin'tat or above high-water mark, which will be more fully described by reference to the accompanying drawings, in which Figure '1 showsapile with thcmvcring upon it.- outer protecting-case made in two parts. Fig. 3 shows this casing made in onc part.

In order to prepare the piles, having lirst ascertained the depth to which they are to be driven and the depth of the water in which they will stand, the piles A are placed in a suitable lathe or nmohine; in which the bark and outer surface of the pile are turned off to a small depth, and so as to produce a smooth and regular surface over that portion which will'extend frointhe mud to the high-water mark. This turned portion of the pile is then coated with a preparation of resin, coal-tar, pitch, asphaltum, orotzher like or suitable material or combination of materials, 13, for pre- This substance is put on boiling hot, and after its application this portion of the pile is wrapped with a suitable flexible fibrous eovering-- which may be either cotton cloth, canvas,

C \vhich is wrapped closely around the part which has already been treated as above described. This being done, a second coating of the-preparation first named is put on over the fibrous wrapping material and allowed to harden. In order to protect this'coating from Fig. Bis :1 transverse scction showingthe r exterior abrasion and wear a sheet or sheets of galvanized iron, steel, copper, or other metal, E, are bent into a vlindrical or semievlimlrimrl l'orm oi sullicient length and diameter to inclose the port ion of. the pile which has been treated as above describm'l. When made in two parts, which is usuallythe most convenient, each of the halves is bentto fit one-hall of the circumt'crence of the pile, and is provided with outwardly-projeeting flanges I), having holes bored orpunchedthrough the flanges. 'lhese holes maybe from four to ten inches apart -und large enough to receive bolts or rivets, which may be secured either b nut-s or by rivetin as is found mostdcsirnble.

'hen the metallic covering does not ex- 'I :ictly fit the intcrior pile, so that there are spaces lel't between the flanges, these spaces will be filled with packing of fibrous material saturated with the pitch or asphultunl prepaoakun1,jutc, Manila cloth, or other material,

ration, thus l'orniing a compact and impene-v. l

trable coverin :it all Joints.

The sheets of metal used may be of anyde- 4 sired thickncsslrom one-twentieth to one hull. ol'nn inch. In some casesit: maybe found preferable to make the inclosing-shect of a single piece, which will be cylindrical in form, having flanges only on one side. In order to prevent these inelosing metallic cylinders or casings from slipping down from their places holes are punched or bored through them and through thcbody of the pile, into which bolts or spikes may be placed to hold the covering in place and prevent displacen'ient from the concussion of the pile-driver.

By turning the piles, which are more orless tapering, that portion which is to be treated is made smooth throughout its length, and the outer metallic using is thus easily fitted and drawn together by the bolts or rivets, so to close tightly at the bottom and top, and thus prevent any access of the insects to the part usually exposed to their ravages.

Having thus described our invention, what we claim as new, and desire to secure by Let'- ters Patent, is

1. The improvement in pile-covering, consisting of the pile turned to a smooth surface between the points which are to be protected, a coating consisting o apreparation of pitch or asphaltum, followed by a fibrous Wrapping, and at second coating of the material, and a final inclosure or covering of metal, substmitially as herein described.

2. The pile having the surface to be protected turn'ed'smooth, a coating of protecting material spread over this surface, a wrapping I of cloth or fibrous material outside of the coating, and a linel coating of material outside of the wra 'iping, in combination with :1. flanged (j'ylindrica-l metallic casehzwing bolts or rivet holes in the flanges, and a hole or holes, by which it is secured directly to the pile, substantially as herein described.

3. A pile-protector consisting of the exterior cylindrical metal casing having the flanges with bolt or rivet holes, by which it is drawn together about the pile, in combination with a packing or filling for the joints, substantiztlly as herein described.

In witness whereof we have hereunto set our hands.
