APPARATUS FOR PROTECTING PILES,

ing members I5 at each side of the protective
This invention relates to the erection of pro
tective structures around concrete, masonry, or
other work such, for example, as piles, piers and
docks. The object is to provide an economical
s and easily erected structure which will give ample
protection against damage due to frost, ice action,
or abrasive or erosive action of any kind.
According to this invention a skeleton frame,
including vertical corner angles7 is first erected
around the structure to be protected and the sides
lO
of the frame then closed oil by boards or other
sheeting members placed one on top of the other
so that the ends of the boards or sheeting mem
bers of each side are held in place by the corner
15 angles and also by interlocking engagement with
the sheeting members of the adjacent side or
sides.
Proceeding now to a more detailed description
reference will be had to the accompanying draw
ings, in which

Fig. l is a View, in side elevation, of the pro
tective structure as applied to a single concrete
pile.
Fig. 2 is a horizontal section taken substantially
along the line 2_2 oi Fig. l.
Fig. 3 is a sectional View along the line 3-3 of
Fig. l.
Fig. 4 is a sectional view along the line 4-4 of
Fig. 2.
'
Fig. 5 is a view similar to Fig. 2 but showing
30 a modification of the invention as applied to a
pile cluster.
In the construction shown in Figs. l to 4 in
clusive, 5 designates a concrete pile and 6 the
protective structure which is erected around the
pile in accordance with the present invention.
As here shown the protective structure com
prises vertical corner angles ’I which are spaced
from the corners of the pile by top- and bottom
timber frames generally indicated at il and 9,
4O
Each of these timber frames consists of four
timbers I0, I l, I2 and I3 assembled in rectangular
formation with their inner edges engaging ad
jacent sides of the pile as clearly shown in Figs.
45 3 and 4. The ends of the timbers Ill and Il
are reduced in ‘thickness and interlock with the
similarly reduced ends of the timbers I2 and I3,
as indicated at ifi in Figs. 1 and 4.
At each side of the pile the space between the
corner angles l is closed off by a series of boards
or sheeting members I5 placed one upon the
other in edge to edge relation, with their end
portions received within the corner angles as
55
clearly shown in Fig. 2. In order to prevent in
Ward displacement thereof the boards or sheet
structure are interlocked, as indicated at I'l, with
the boards or sheeting members oi the two ad
jacent sides. The top timber frame t rests
directly on the uppermost boards or sheeting
members I5 and serves to hold said members
against vertical displacement.
The entire protective structure is secured in
place around the pile by suitable fastening bolts
indicated at I8 and I9. As clearly shown in Fig.
3, these bolts serve to clamp the corner angles 'I
against the corner portions oi the timber frames
8 and 9 which, in turn, may be directly fastened
to the pile in any desired manner.
The space between the pile and the boards 15
or sheeting members I5 of the protective struc
ture may be left void or may be filled with gunite
or any other suitable material. In the present
instance I have shown a ñlling 2t oi gunite pro~
vided with metal reinforcement generally in
dicated at 2 I.
The protective structure described in the fore
going is erected by ñrst applying the lower timber
frame 9 and the corner angles 'I. rI‘he boards or
sheeting I5 are then arranged in place and s_e
cured against Vertical displacement by the uppertimber frame 8. The corner angles 'I may be
secured to the timber frames 8 and 9 in any
suitable manner, in addition to being held in
place by the bolts I8 andy I9.
30 `
Fig. 5 illustrates the manner in which the pro
tective structure may be erected around an exist
ing pile cluster. In this case corner ñller pieces
22 may be employed at the corners 23 instead
of metal corner angles. It will also be noted
that certain of the fastening bolts I8 and Iii
employed for holding the protective structure in
place are anchored either in the piles or in por
tions of the gunite filling which is placed in the
spaces between the individual piles and between
the piles and the protective structure. Aside
from these differences and the necessary varia
tion in shape the protective structure shown in
Fig. 5 is essentially the same as that shown in
the preceding figures.

Having thus described my invention, what I
claim is:
1. A protective enclosure for piles, piers, docks
and similar structures comprising vertically
spaced top and bottom frame members mounted 50
on the structure to be protected, vertically ex
tending angle irons engaged with corner portions
of said frame members, said angle irons being
spaced from said structure, and superposed sheet
ing members extending between the angle irons 55

2,109,105
at each side of said structure, the sheeting mem
bers at each side of the protected structure being
held against vertical displacement between the
top and bottom frame members and being held
against horizontal displacement by said angle
irons and by interlocking engagement with the
sheeting members at the adjacent sides of said
structure.
2. A protective enclosure for piles, piers, docks
10 and similar structures comprising vertically
spaced top and bottom frame members mounted
directly on the structure to be protected, vertical
angle irons clamped to corner portions of said
frame members, superposed sheeting members
extending between the angle irons at each side
of the protected structure, the ends of the sheet
ing members at each side of said structure being
positioned inside the adjacent flanges of the
angle irons and being interlocked with the ends
of the sheeting members at adjacent sides of
said structure, the interlocking connection be
tween the sheeting members being such as to
prevent inward displacement thereof toward the
protected structure.
3. A protective enclosure for piles, piers, docks
and similar structures comprising vertically
spaced top and bottom. frames mounted directly
on the protected structure, vertical angle irons
clamped to corner portions of said frames, super
posed side boards extending between the angle
irons at each side of said structure, the side
boards at each side of said structure being spaced
therefrom and being held against vertical dis
placement bythe top and bottom frame members,
and suitable filling material disposed in the space
reserved between the protected structure and the 10
angle irons and side boards of the protective en
closure.
4. A protective enclosure for piles, piers, docks
and similar structures comprising vertically
spaced top and bottom frame members mounted 15
directly on the protected structure, vertical angle
irons engaging corner portions of said frame
members, each angle iron being fastened to the
two adjacent angle irons by clamping bolts serv
ing to yclamp the angle irons firmly against the 20
corner portions of the frame members and sheet
ing members extending between the angle irons
at each side of the protected structure to form
vside Walls extending from the bottom to the top
frame member to complete the enclosure.
