UNITED STATESPATENT OFFICE
JOH\ T. FARRELL, OF HOUSTON, TEXAS.
DERAILER.Specification of Letters Patent.
Patented Nov. 16, 1909.
Application filed April 30, 1908. Serial No. 430,050.
To all whom it may concern:
Be it known that I, Jonx T. FARRELL.
citizen of the United States, residing at
Houston, in the county of Harris and State
5 of Texas, have invented certain new and use-
ful Improvements in Derailers, of which the
following is a specification.
My invention relates to new and useful
improvements in derailers.
10 The object of the invention is to provide a
superior derailer of simple construction
which may be operated from a switch stand
if desired or locked on the rail.
Another object is to provide a device of
15 the character described that will be strong,
durable, efficient and simple and compar-
atively inexpensive to construct, also one in
which the several parts will not be liable to
get out of working order.
20 With the above and other objects in view,
the invention has relation to certain novel
features of construction and operation, an
example of which is described in the follow-
ing specification and illustrated in the ac-
25 companying drawings, wherein:
Figure 1is a plan view of the derailer and
a portion of the track, Fig. 2 is a side eleva-
tion of the same, Fig. 3 is a transverse sec-
tion of the derailer block, Fig. 4 is an end
30 view of the parts shown in Fig. 1, Fig. 5 is
an inside elevation of the derailing block,
Fig. 6 is a plan view of the bracket, and Fig.
7 is a rear elevation of the same.
In the drawings the numeral 1 designates
35 an ordinary rail supported on the ties 2. To
the outer side of the web 3 a bracket 4 is se-
cured by a suitable bolt 5 so as to project
horizontally toward the inside of the track.
This bracket is formed with side arms 6 and
40 a pocket 7 shaped to snugly receive and fit
the outer base flange of the rail.
Between the side arms 6 a derailing block
8 is pivotally mounted on a bolt 9, the said
bolt passing through one of a plurality of
45 openings 10 in each side arm which permits
the said block to be adjusted vertically to
accommodate different heights of rails and
laterally to accommodate different forma-
tions of rail treads such as an L formation.
50 This block is curved upwardly and formed
with a shoe portion 11 which rests on the rail
1 and projects over the same at 12 where it
slopes down toward the outside of the track,
while at its opposite end 13 it slopes down
55 toward the inside of the rail.The shoe portion has a diagonal groove
or channel 14 which begins inside of the
head of the rail and ends outside of the
same. The groove 14 and the block are
properly shaped so that. the flange of the 60
wheel will ride into the groove and be
guided across to the outside of the rail and
the derailing properly carried out. The
block is provided with a projection 15 adja-
cent the groove against which the flange of 65
the wheel will strike and be thrown toward
the rail as it leaves the block.
At its lower end, the block is provided
with a slotted opening 16 to receive a suit-
able connection from a switch stand by 70
which the block, being pivotally mounted,
may be swung on to the rail or raised off of
the same and thrown back when it is not de-
sired to use the derailer. An eye 17 is pro-
vided on the shoe 11 to receive a locking key 75
18, one end of which is secured to a chain 19
having suitable connection with one of the
track bolts. By this arrangement the block
may be locked into position when it is de-
sired to use it permanently on the rail, as at 80
the end of a siding.
I wish to call particular attention to the
fact that the block 8 is pivoted some dis-
tance above its lower end which permits it
to be readily swung off of the rail when it is 85
not desired to use it and to be thrown down
on to the rail whenever desired. By arrang-
ing it to be connected to a switch stand it
may be locked in or out of operating posi-
tion just the same as an ordinary switch 90
tongue.
What I claim, is:
1. In a derailer, the combination with a
rail, of a bracket secured to the rail and pro-
vided with side arms having a plurality of 95
bolt receiving openings, a grooved block dis-
posed between the side arms, and a bolt pass-
ing through one of the openings in each side
arm and the block for pivotally and adjust-
ably supporting the same. 100
2. A derailer of the character described
comprising supporting means adapted to be
located adjacent to a rail, a block 8 pivoted
to said support adapted to rest upon a rail
having the shoe portion 11 and the projec- 105
tion 15 arranged substantially as and for the
purpose described.
3. A derailer of the character described
comprising a support adapted to be mounted
adjacent to a rail, a block 8 pivoted to said 110940,139..
