COMPLETE SPECIFICATION.
Certain Improvements in Pile-coverings.
I, ALMON AMES, of Berkeley, County of Alameda, and State of California, one of
the United States of America, Gentleman, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
My invention relates to certain, improvements in covering devices for protecting
piles from the ravages of marine insects and worms.
It consists of a sheet-metal casing fitted to surround each pile, and a means
whereby said casing is more efficiently applied to the pile and fixed thereon.
Referring to the accompanying drawings,
Figure 1 is a view showing the application of my covering to a pile.
Figure 2 is an enlarged view of one of the metallic sections.
Figure 3 is a transverse view of the same.
Figure 4 is a view of one of the channeled bands.
Figures 5, and 6 are transverse sections showing another form of joint for the
metal covering section.
In applying my improved covering to a pile, I first turn the pile into a smooth
tapering surface by any suitable apparatus, and then I form sections of sheet-metal,
which sheets are of such size as to entirely wrap and envelope the pile, so that I am
only obliged to form one longitudinal joint of these metal sections.
There are two ways in which I may apply this covering.
If the metal is light and thin, it may be wrapped around the pile, and the folded
joint, shown in Figures 5, and 6, may be formed by a suitable apparatus after the
sheet is wrapped around the pile, and each successive section may in like manner be
wrapped around the pile and the joint formed as herein shown; after which the
sections, which may overlap and be riveted together at their point of junction, are
surrounded by bands C, to further insure a tight joint at this point.
When heavy sheet-metal is to be used for the purpose, the sections A are first bent
around a former and riveted together, as shown in Figures 1, and 2, so as to form
tapering sections of such a size as to fit the different portions of the pile to which
they are to be applied.
Over the meeting-edges of these sections are riveted the longitudinal strips D, and
these strips have formed at the upper and lower ends projecting pieces E. The
sections A are forced upon the pile from the smaller end, the upper section being
forced up to a point where it fits snugly around the pile; the next section abutting
against the lower end of the first one, and so on until as much of the pile has been
covered as may be desired.
Bands are then forced on by hydraulic or other suitable pressure over the
sections A, until they cover the meeting ends of these sections.
Each of these bands C is formed with a channel, as shown at F, which channel
fits over the riveted strip D. This channel is enough wider than the width of the
strip D, to also take in the projecting lugs E of the upper and lower end respectively
of the meeting-sections A.
The lug E at the upper end of each section has a horizontal slit or cut made in it,
and the band is forced on to a point just above this slit which is plainly shown at a,
and after the band is in place the lower portion of the lug E is bent outward
beneath the band, and this prevents it from ever slipping off or getting out of place.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is :-
1. A pile-covering, consisting of sheets of metal wrapped around. the pile and

page_text: having their meeting-edges united so as to form a single longitudinal joint, in com-
bination with rings or bands which fit over the adjacent meeting-ends of said sections
and the joints, substantially as described.
2. A pile-covering, consisting of the sections formed of single sheets of metal
having their edges united. so, as, to form a single longitudinal joint, and fixed
successively upon the pile so that their adjacent ends abut together, supplemental
strips riveted upon the sections so as to cover the longitudinal joint, and rings or
collars having channels or depressions adapted to fit the supplemental strips when
the rings are driven or forced upon the sections so as to cover the meeting-ends
thereof, substantially as described..
3. A pile-covering, consisting of sections formed of single sheets of metal having
their meeting-edges joined together, a supplemental re-enforcing strip riveted over
said. meeting-edges and having the projecting lugs E at opposite ends, and rings or
collars having channels formed in them so as to fit over the supplemental strips and
lugs and be locked in place by means of said lugs, substantially as described.
