(Cl. 254-21)
This invention appertains to new and useful
improvements in means for pulling spikes from
railway ties and other structures without caus
ing distortion of the spike head. There is in
use at present a spike having an arched head
structure with which the present invention is
especially adapted for use, thisparticular spike
structure forming the basis of Patent No. 2,015,
194 issued September 24, 1935.
The principal object of the present invention
is to provide a simple device which can be read
ily fastened to the head of a spike so that a
claw bar can be used in conjunction therewith
without resulting in such malformation of the
spike head as to prohibit its further use.
Other important objects and advantages of
the invention will become apparent to the reader
of the following specification.
_In the drawing:
Figure 1 represents a vertical sectional view
fragmentarily showing a tie and rail and the
puller in side elevation.
Figure 2 is a fragmentary top plan view.
Figure 3 is an end elevational view.
Figure 4 is a plan view of the key.
25
Figure 5 is a vertical sectional view taken sub
stantially on the line 5-5 oi Figure 1.
Referring to the drawing wherein like nu
merals designate like parts, it can be seen that
numeral 5 represents the standard railway tie
upon which the usual plates 6 are placed for
supporting the rails 1.
The plate 6 is provided with spike openings
therein which are registrable with bores 8 formed
in the tie for the reception of the spike shank
9. Numeral I Il generally refers to the spike which
as shown is of special design such as is clearly
represented in Patent No. 2,015,194, issued Sep
tember 24, 1935. This type of spike is formed by
bending an elongated rod of square cross sec
tion back upon itself and then bending the free
end portions laterally to form an arch-shaped
head formation. This head formation is de
noted by numeral II and its free end portion
45 bears upon the rail base shown in Figure 1 when
the spike is completely driven into the tie 5.
Thus it can be seen that with this form of
spike the puller generally referred to by numeral
I2 can be readily and eiiiciently used.
The puller I2 consists of an arch-shaped por
tion I3 curved in the opposite direction from the
rocker runners I4-I4. This arched portion I3
and the runners or rockers Ill-I4 are construct
ed in one piece and this body has one end curved
downwardly as at I5 and its opposite end like
55
Wise curved downwardly and provided with a
notchway I6 for the reception of the free end
of the spike head.
The key generally referred to by numeral I6
consists of the key head Il and the slotted arm Ui
I8, the key head I1 and arm I8 being in parallel
relation and connected by the shank I9.
A machine screw or the like 2l] is disposed
through the slotted arm I8 and into the end
portion I5 of the puller I2 so that the key head
I'I can be slid inwardly or outwardly with respect
to the puller.
When it is desired to apply the puller, the de
vice is set upon the spike so that the arched
portion I3 rests upon the arched spike head while
the runners III-_I4 depend at opposite sides of
the spike head. The key Il is now slid inwardly
under the arch I3 and also under the head
II of the spike I0 thus latching the device to the
spike head. The puller is now in position to be 20
rocked.
A claw bar 2l can now be used by placing its
head under the portion I5 of the puller and
gradually lifting up on the puller as the claw
is inserted. Thus the puller is rocked and in so 25
being rocked gradually pulls the spike from the
tie.
While the foregoing specification sets forth
the invention in specific terms, it is to be under
stood that numerous changes in the shape, size 30
and materials may be resorted to without de
parting from the spirit and scope of the inven
tion as claimed hereinafter.
Having described the invention what is claimed
as new isz
1. A puller for pulling spikes of the arched
head type comprising a plate having one end
portion formed to facilitate the engagement
thereunder of a prying tool, an arch-shaped for
mation on the plate for engagement over the
top of a spike head, and a member on the plate
shiftable for disposition under the head portion
of a spike.
2. A puller for pulling spikes of the arched
head type comprising a plate having one end
portion formed to facilitate the engagement
thereunder of a prying tool, an arch-shaped for
mation on the plate for engagement over the
top of a spike head, and a member on the plate
shiftable for disposition under the head portion 50
of a spike, said shiftable member consisting of
a pin and a slidable connection between the
pin and the plate.

3. A puller for pulling spikes of the arched
head type comprising a plate having one end 55

portion formed to facilitate the engagement
head type comprising a plate having one end por'
thereunder of a prying tool, an arch-shaped for
mation on the plate for engagement over the
top of a spike head, and a member on the plate
shiftable for disposition under the head portion
tion formed to facilitate the engagement there
under of a prying tool, an arch-shaped forma
tion on the plate for engagement over the top
of a spike, said shiftable member consisting of
a pin and a shiitable connection between the
pin and the plate, said slidable connection con
sisting of an arm on the pin having an opening
10 therein and a securing element disposed through
the openingl and into the plate.
4. A puller for pulling spikes of the arched
of a spike head, and a member on the plate
shiftable for disposition under the head portion
of a spike, said plate being in the form of a
rocker and adapted to rock When moved by a
prying tool.
