TIE PULLER
Joseph A. Denton, Milwaukee, Wis.
Application October 22, 1936, Serial No. 106,964
2 Claims. (Cl. 254—43)
This invention relates to an improvement in tie is designated generally at P and in Figure 1 is
illustrated in one of its operative positions for
pullersespecially designed and adapted to facili
tate the removal and replacement of railway ties.
One of the principal objects of the invention is
r. to provide a tie puller which is extremely simple
in its construction, although effective, reliable
and safe in operation and easily handled and
_ operated.
More particularly, the tie puller em
bodying said invention is so designed that even
10 when it is positioned for removing a tie it does
not present any obstruction to the safe and nor
mal passage over the rails of a train. Hence,
any danger of derailing a train or of otherwise
injuring the same due to the use of the tie puller
‘.5. is precluded or avoided.
Another object of the invention is to provide a
tie puller which is so constructed so that it may
be simply laid in place on the ties and engaged
with the web of one of the rails, and yet when it
20, is operated to set up tension in the cables which
interconnect the tie puller with the tie the ten
sion on the cables will also be effective to securely
pulling a tie from beneath the rails after the
spikes, some of which are designated at S, have
been removed.

The tie puller comprises a frame III which may
‘have the general form of an angle iron, although
its lower ?ange is arched or cut away as at H
to provide clearance between the underside of
the frame and the particular .tie which is being 10
withdrawn. The undersides of the end portions
of the frame I0 rest on the tops of the ties which
are disposed on the opposite sides of the tie be
ing removed. Adjacent its ends‘the frame may
be provided with suitable handles l2.

Integral with or otherwise suitably and rigidly
connected to the frame is a pair of laterally ex
tending spaced arms l3. The outer ends of these
arms are enlarged or thickened and also suitably
shaped-as indicated at M to better adapt them 20
to abut against the web of a rail in the space
between the lower adjacent portion of the tread
and ?rmly hold the tie puller in position.
of the rail and the base thereof, as clearly shown
Another object of the invention is to provide in Figure 2. At their juncture with the frame
10 the arms I3 are enlarged or thickened and 25
25 a tie puller in which variable speed and power
ratios are readily available and this without apertured to" provide bearings I5 for the shaft
iii of a double drum Windlass designated gen
complicating the construction of the device.
Other objects and advantages reside in certain erallyby the reference character‘ W.
The Windlass W comprises‘ drums l1 and 18'
novel features of the construction, arrangement
30‘ and combination of parts which will be herein ‘which are rotatably mounted on the shaft l6 3.0
after more fully described and particularly point
adjacent the bearing members 15 in‘ which the

puller constructed in accordance with the present handle 2| and a bifurcated lower end 22, the legs
of the bifurcation designated at 23 being pro
invention in operation in pulling a tie from a sec
vided with openings through which the shaft l6

Referring to the drawing and more especially
to Figure 1, the reference character R designates
generally a section of a railway track having the
usual ties T and rails R1 and R2.

The tie puller embodying the present invention
extends whereby to provide a fulcrum or mount
ing shaft for the operating lever. In between the 40
legs 23 of the bifurcated lower end of the oper
ating lever the shaft I6 is supported in a bearing
24 which is formed in an integral extension of
the frame 10. Pivoted to the outside face of each
leg 23 of the bifurcated lower end of the operat- 45
ing lever is an operating pawl 25.
There is one
such pawl for the ratchet wheel I 9 of each drum.
For preventing retrograde motion of the drums
I1 and I8 detents 26 .are provided, the detents
being loosely pivoted on a short supporting shaft 50
21 mounted in bearings provided therefor in lugs
28 which may be cast or formed integral" with
the frame Ill.
‘
'
Cable means is associated with the drums of
the Windlass and preferably comprises a suitable 55
2
2,133,851
cable of rope or wire designated at 30 and having
its ends suitably secured to and wound or coiled
about the drums I ‘I and I8. In the bight 3| of
the cable'an abutment member 32 is suitably se
cured and is designed to afford a better inter
connection between the bight of the cable and one
'end of the tie to be removed.
For the purpose of limiting the distance to
which the operating lever 20 may be swung in one
10 directionthe lower portion of the handle 20 is
provided with a stop ?nger 35 engageable with
the frame ID as indicated in Figure 4 when the
lever has been swung back through its idle stroke
as far as it should be.
In using the tie puller to remove the tie it may
be placed in the position shown in Figures 1 and
2, that is, with the frame resting on ties disposed
on the opposite sides of the one to beremoved
and with the arms l3 engaged with the web of the
rail as illustrated. The cable is then passed down
under the railsv and its abutment 32 is engaged
with the end of the tie opposite the tie puller.
Then by moving the lever‘ 20 back and forth the
cable 30 is wound up on-the drums I1 and i8 and
25 the tie is slid from beneath the rails. It will be
understood that as the lever is rocked forwardly
the pawls 25 engage the ratchet wheels l9 to im
part a partial revolution to the drums l1 and i8.
As the lever 20 is rocked back the pawls 25 idle
30 or click over the teeth of the ratchet wheels l9
while the ratchet wheels 19 and their drums l7
and I8 are held against an unwinding movement
by the detents 26.
The drawing illustrates only one operative po
35 sition of the tie puller. Where a new tie is to be
slid into place as an old tie is removed, the new
tie is alined with the old tie and has one end
abutting the same, as illustrated in Figure 1.
If the tie puller is then‘positioned as shown in
40 Figure 1 then the cable 30 must be of consider
able length. A shorter length of cable may be
utilized to carry out this operation by shifting
the tie puller over to the inside of rail R2 so that
the arms l3 engage the inside of the web of the
rail R2. Such position of the tie puller isalso
resorted to when removinglong switch ties.
In case a tie is very di?icult to remove and
more power is required for its removal than is
available by operating the puller in the manner
50: mentioned the power ratio may be increased by
having the cable 30 slide around its abutment 32
or travel about a pulley thereon and throwing
one of the pawls 25 to inoperative position. In
such case only one Windlass operates but the pow
, er available is doubled due to the cable action;
One of the important features of the invention
resides in so constituting the structure of the
puller that the part engaging the rail does not
project up to the tread of the rail or overlie the
same. Hence, the wheels of a train and the
flanges‘ of the wheels are not interfered with as
the train rolls along the track and over the entire
puller. The handle 2| would have to be removed
if the tie puller occupied an inside position.
Another feature of distinct advantage is the
fact that the cables 3!) lead off of the lower sides
of the drums l1 and 18 so that when the device‘
is in use and the cable 39 is under tension the
tension of the cable aids in holding the tie puller
securely and ?rmly in position.‘
In connection with the features just enumer
ated, it is to be understood that the advantages
thereof may be realized even though the par
ticular means for maintaining the puller in po
sition under the in?uence of the tension of the
cables is varied. More speci?cally, While the
arms l3 provide a structure having its own dis
tinct advantages, it is possible to provide, in lieu
of these arms, lugs or other structure on the
frame which engage with the ends of the ties
disposed on the opposite sides of the tie to be re
moved, provided such structure is kept below, the
plane of the active tread portion of the rail and is
such as to respond to the pull or tension of the 10
cables.
While I have shown and described one con
struction in which the invention is advantage
ously embodied, it is to be understood that this
construction has been selected merely for the 15
purpose of illustration or example and that vari
ous changes in the size, shape and arrangement
of the parts may be made without departing
from the spirit of the invention or the scope of
the subjoined claims.
The invention claimed is:
20
1. A tie puller of the character described com
prising a frame adapted to rest on the ties and
having means for securing it in position, a wind
lass including a pair of independently rotatable 25
drums supported on said frame, ratchet wheels
interconnected and having driving relation with
said drums, an operating lever, driving pawls in
dependently pivoted to said lever and selectively
or simultaneously cooperable with said ratchet 30
wheels, said driving pawls and said ratchet wheels
being designed so that when both pawls are
simultaneously cooperable with the ratchet
wheels they will be effective to drive both drums
on one stroke of the lever and will idle over the 35
ratchet wheels on the opposite stroke, and said
driving pawls being similarly operative when in
dependently engaged with their respective ratchet
wheels, means for preventing retrograde motion
of said drums, and cable means connected to
said drums and adapted to engage a tie and to be
effective to pull it out under the simultaneous
drive of .both pawls or under the independent
actuation of either, said cable means having an
intermediate portion traveling about an end of 45
the tie when said cable means is anchored to one
of the said drums and actuated solely by the
other.
2. A tie puller of the character described com
prising a portable frame having means engage 50
able with the rail below the tread surface thereof
to maintain the tie puller in position, bearings
carried by the frame, a shaft supported in said
bearings, independently rotatable drums mount
ed on said shaft, a lever pivoted on the shaft 55
between the drums, said drums having ratchet
wheels adjacent the lever, said ratchet wheels
having their ratchet teeth facing in the same
direction, pawls individually pivoted to the lever
and selectively and simultaneously cooperable 60
with said ratchet wheels, and a cable having its
ends secured to» and coiled about the drums and
having its bight portion adapted to engage an
end of a tie whereby when the pawls are simul
taneously cooperable with the ratchet wheels the
device may be operated to withdraw a tie rapidly
and when only one of the pawls is engaged with
its one of said ratchet wheels increased power is
available to effect the pulling of the tie due to the
cable action, the bight of the cable traveling
around the end of the tie with which it is engaged
when the cable is actuated under the in?uence of
one only of said pawls. '
