COMPLETE SPECIFICATION.
Improvements in Piles and the like, and in Means for Protecting
them from Water Insects and Preserving them Generally.
I, HUGO GALLINOWSKY, of the Town of Longbeach (no street or number), in
the County of Harrison, and State of Mississippi, United States of America,
Chemist, a citizen of the United States, 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 improvements in protected piles and has for its object
the preservation of all forms of wood which enters into the construction of partially
or wholly submerged structures, as wharfs, bulk heads, bridge piers, jetties, break
waters, etc. In addition to preserving wooden structures from the deleterious
action of sea water and other forces, the said invention is particularly adapted to
the preservation of the said structures against destructive aqueous insects.
The said invention consists of the novel structure and composition hereinafter
more fully described and pointed out in the claims.
Reference is had to the accompanying drawings in which
Fig. 1 represents my improved protected pile in side elevation, and
Fig. 2 represents a central longitudinal sectional view of the saine.
Similar letters refer to similar parts throughout the several views.
A represents a pile with the head a and tapering towards the end a'. The pile.
is diminished in diameter between the shoulders a' and a', upon which part a
protecting substance is wound flush with the surface of the pile.
This protecting substance B consists of any suitable fibrous material, as jute or
cotton fabric treated and applied to the pile in the following manner:
The fabric is first subjected to a bath of horacio acid, after which it is passed
through a set of rollers or other pressure which presses the greater portion of the
acid out.
After having been pressed as above described, the fabric is then subjected to a
bath in a saturated solution of magnesium chloride; then the said fabric is put in a
Lath of hydrated magnesium oxide containing about five per cent. of sal-ammoniac,
and again pressed. The pile being placed in a position to rotate, one end of the
fabric so treated, is attached to the pile, which is then made to revolve, causing
the fabric to wind on said pile.
Before the said fabric reaches the pile it is passed under sufficient pressure to
squeeze out the required amount of liquid.
This fabric is then wound on the pile as above described between the shoulders a³
and a until it becomes flush with the surface of the pilo when the winding may be
discontinued.
The fabric so treated and wound on the pile cements together and becomes
extremely hard and tough. It will be seen that the pile is not protected through-
out its entire length by this substance, it being found unnecessary to provide the
cap a above the water and the end a¹ which is buried in the earth with such
protection.
This protection is carried sufficiently high on the pile to be above the high
water mark as represented at C.
To more thoroughly protect the pile and especially the top a against decay, and
to give the protecting cover itself an everlasting quality. the pile is given a bath

page_text: in creosote or other wood preserving oils. The pile is only dipped in the creosote
far enough to cover the end a aud protecting cover B, though, if preferred, the
whole pile may be subjected to the creosote bath.
The pile thus wrapped with the protecting substance B and treated with
creosote is enabled thereby to withstand the most severe attacks from external
agencies, and is particularly well protected against the attacks of that enemy
known as the teredo..
While I have shown a certain form of pile and described certain steps in the
process of protecting the same, it is obvious that changes and modifications may be
made without departing from the spirit of my invention.
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. The protective covering for piles, substantially as hereindescribed and shewn
in the drawing hereunto annexed..
2. A protective covering for piles and other timbers composed of fibrous material
compounded with boracic acid, magnesium chloride, hydrated magnesium oxide and
sal-ammoniac, substantially as described and shewu.
3. A pile covered throughout a portion of its length with a substance consisting
of fibrous material, compounded with boracic acid, naguesium chloride, hydrated
magnesium oxide and sal-ainmoniuo, substantially as described and shewn.
4. A pile or other timber, covered throughout a portion of its length with a
substance composed of fibrous material compounded with boracic acid, magnesium
chloride, hydrated magnesium oxide and sal-ammoniac, and filled with creosote,
substantially as described and shewn.
5. A pile covered throughout a portion of its length with a substance consisting
of fibrous material compounded with boracic acid, magnesium chloride, hydrated
maguesium oxide and sal-ammoniac; and diminished in cross section where said
covering is applied, and filled with creosote with said covering on, substantially as
described and shewn.
6. In the protection of piles and other timbers, the process which consists in
subjecting fibrous material to a bath of boracic acid, then pressing a portion of
said acid out, then subjecting said fibrous material to successive baths of magnesium
chloride and hydrated magnesium oxide with sal-ammoniac, then pressing the said
fibrous material so treated and wrapping the same on the timber to be protected,
and then subjecting the timber with covering on, to a bath of creosote, or other
wood preserving oil, substantially as described and shown.
