Description
RELATED APPLICATIONS
[0001] The following is an application under 35 USC 111 (a). This
application claims priority to U.S. Provisional Application No.
62/888,760 filed Aug. 19, 2019 and priority to U.S. Ser. No.
16/997,109 filed Aug. 19, 2020. The present application is a
divisional application of U.S. Ser. No. 16/997,109.
FIELD
[0002] This invention relates to a composition, mechanical device,
and method for improving retention of anchors in wood structures,
filling holes left by anchors in wood structures to maintain
structural integrity of the structure, and more particularly, to
composition, device, and methods for removing, driving, and
replacing railroad spikes in wood cross ties.
BACKGROUND
[0003] The railroad industry has historically been plagued by the
loosening and loss of rail spikes from wood cross ties, and
periodically undertaken a variety of efforts to improve spike/tie
interface. Spike loss is caused by the lateral and vertical
movement of a rail under load that creates ratcheting effect on the
rail spike and the tie. This ratcheting eventually results in
loosening and dislodgement and loss of the spike causing the wood
cross tied and rail plate connecting the tie to the rail line to
become loose and rail above it to be unstable. When this happens,
the spikes must be replaced to maintain integrity and safety of the
rail lines.
[0004] The traditional industry standard method for replacing
missing spikes involves driving a wooden plug into the whole left
by the lost spike and inserting a new spike into the wooden plug.
This means of replacement leaves the cross tie susceptible to loss
of the spike via the constant ratcheting effect due to movement of
trains over the rails. Railroads must constantly survey for and
replace lost spikes to keep the rail lines in safe operating
condition. Spikes must be replaced when rail or gauging is replaced
for railroads to be in compliance with Federal Railroad
Administration (FRA) rules.
[0005] Wood railroad cross ties are treated typically with creosote
to prevent erosion, splitting, and wood rot. A properly treated tie
can last up to twenty-five years depending on weather and
environmental conditions. Once a spike is driven into the tie, the
area around the spike is exposed to elements and is more
susceptible to wear due to ratcheting forces. This untreated
exposed area around the spike captures moisture and is open to
invasion by living organisms many of which may be microscopic.
Further water freezing and thawing in the wood leads to degradation
of the wood fiber and rot around the spike weakening the bond
between the spike and cross tie. This degradation around the spike
shortens the useful life of the tie leading to premature
replacement. Weakened cross ties are hazardous and must be
constantly inspected and replaced if weak. Spike and cross ties
maintenance and replacement cost much employee time and material
expenses for the rail industry.
[0006] Various mechanical means of improving rail spike retention
have been employed but have done little to address the issue of tie
degradation around a spike and have met with limited success.
Several compounds including a low viscosity resin, as described in
U.S. Pat. No. 4,706,806, expandable dowel compound as described in
U.S. Pat. No. 4,723,389, flowable hardening bonding mass as in U.S.
Pat. No. 4,907,917, and bonding material described in U.S. Pat. No.
5,397,202. These however are not readily adaptable to wood rail
cross ties, involve two stage applications and/or require external
application of heat for mixing the compounds and thus special tools
on site. Moreover, many of these compounds by nature are harmful to
the environment.
[0007] More recently a composition for rail spike retention has
been employed. This dry mixture described in U.S. Pat. No.
6,255,370 required no special tools for application and heat
generated by the driving of the spike into the aperture effected
amalgamation and dispersion in the spike aperture. The dry mixture
included ground aromatic hydrocarbon materials being 25-45% by
weight petroleum pitch, 50-70% sub-angular silica sand having grade
of between 35 and 100 mesh, and a hydrocarbon resin adhesive being
coumarone-indene resin on silicon dioxide at 1-10% of the final
composition.
[0008] The current method of filling holes left following
extraction of metal spikes from wood cross ties is hand-held
application of filler material. A hopper contains material and a
person opens a valve to dispense a compound of choice into the hole
one at a time. What is needed in the art is an efficient, fast,
environmentally friendly, and robust devices, systems, and methods
for preserving wood cross ties and holding spikes securely in place
in order to ensure safety and longevity of rail lines.

delivery tubes 5 with rail spike holes 17B. The unit is positioned
over the rail plate 15 and a laser or other light source mounted on
the device may be used to create an x cross hair line or axis 63
and y cross hair line or axis 64 to position the delivery tubes
over the pattern of spike holes 17B on the rail tie plate 15. FIG.
17B is a further close-up of this process illustrating cross hairs
63, 64 created by a laser or light device aligning the delivery
tubes 5 with the spike holes 17B. FIG. 18 is a close-up view of the
dispensing nozzles 5A. These dispensing nozzles 5A are designed to
swivel in their ports to better align delivery tubes (not shown)
with spike holes. As such the dispensing or delivery nozzle 5A may
swivel or angle at least 5.degree., 10.degree., or at least
15.degree., or at least 20.degree., or at least 25.degree., or at
least 30.degree., or at least 35.degree., or at least 37.degree.

[0046] Further, a composition for filling holes, spaces, or gaps in
wood is disclosed. The wood filler composition may be used in the
process of repairing a railroad line in particular the railroad
wooden cross or cross ties 16, as shown in FIG. 2, but may be
applicable to other wood pieces where there is a need to stabilize
and preserve the integrity of the wood member. Often wood cross
ties 16 and rail spike holes 17B experience deterioration due to
water, mold or other organisms, temperature, and other factors, and
spikes 17A become loose. When spikes 17A become loose, rail lines
move causing problems for trains. As illustrated in FIG. 2, the
wood filler composition provides a medium in which a new or
replacement spike 17C may be inserted or re-spiked into the hole
17B vacated by a rail spike 17A that mimics virgin wood ties. The
wood filler composition comprises in part Gilsonite, also known as
unintahite or asphaltum, and is a natural product being
bitumen-impregnated rock or asphaltite primarily found in and mined
from the Uintah Basin of Utah and Colorado. It is a naturally
occurring solid non-aromatic hydrocarbon bitumen which is a
non-carcinogenic composition. The wood filler composition may
comprise Gilsonite at between about 15 to 60% by weight, or as much
as 20 to 50% by weight, or as much as about 20%, or as much as 25%,
or as much as about 30%, or as much as about 35% Gilsonite of the
total composition. The wood filler composition may further comprise
silica sand, wherein the sand particle shape may be angular in
nature as opposed to a sphere-like particle structure or shape. The
sand may rate on Mohs' Hardness Scale from about an H=2 to an H=10,
or about an H=3 to about an H=9, or about an H=5 to an H=8, or
about an H=5.5 to an H=7. The sand may be present in the
composition from about 40% to about 85%, by weight, or about at
least 60%, or about at least 70%. In addition, the composition may
further comprise additives to prevent wood rot, some being water
repellent compositions chosen, but not limited to those of the
group including zinc, or a zinc compound, being in one example,
zine borate, and may be present in the composition at 1-10%, by
weight, or about 2-8%, or about 2-5%. The composition may further
comprise a wood preservative. It is one purpose of the present
invention to provide an environmentally friendly solution to wood
cross tie preservation. Older wood preservatives including
chromated arsenicals, creosote, and pentachlorophenol have negative
environmental impact. Newer environmentally friendly preservatives
may include propiconazole, triadimefon, acid copper chromate,
alkaline copper quaternary (ACQ), borate, copper azole, copper
naphthenate, copper-HDO (Bis-N-cyclohexyldiazeniumdioxy-copper),
and polymeric betaine. The presently disclosed wood filler
composition offers an improved environmentally friendly
composition.
[0047] A method for filling holes in wood members is disclosed. As
shown in FIG. 2, the wood filler composition is inserted into a
wood member, like a wood cross ties 16 in the rail spike 17B holes
once the rail spikes 17A are removed, to stabilize the structure of
the wood. Particularly, the wood filler composition described
herein may be used in a method for railroad rail or cross tie
repair. As noted before, rail spikes 17A hold the rail tie plates
15 to the wooden cross ties 16. As these rail spikes 17A become
loose due to decomposition of the wood they need to be replaced. In
the method of the present invention at least two holes may be
filled with wood filler composition at one time, or three or four
may be filled at one time, or five or six, or seven or eight, or
more. In practice, once a rail spike 17A is removed, by hand or
tools, the wood filler composition described herein is dispensed
through the delivery tubes 5 simultaneously into each rail spike
hole 17B by the disclosed device 1, FIG. 1, described above. Once
the wood filler composition is placed in the holes, a new rail
spike 17C may be inserted onto or in the composition filled
hole.
[0048] Although the present invention has been described with
reference to the disclosed embodiments, numerous modifications and
variations can be made and still the result will come within the
scope of the invention. No limitation with respect to the specific
embodiments disclosed herein is intended or should be inferred.
Each apparatus embodiment described herein has numerous
equivalents.
