Improvement in Devices for Preventing Railway-cars from
Leaving the Rails.
I, CHARLES WILLIE MOBRYER, Architect, residing at Wellston Post Office,
in the County of St. Louis, State of Missouri, and United States of America,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :—
•
My invention relates to improvements in "Devices for Preventing Railway-cars
from Leaving the Rails," and consists in the novel arrangement and combination of
parts, as will be more fully hereinafter described and designated in the claims.
The object of any invention is as above stated to constrict certain devices for
the prevention to a great extent of the many railway accidents now caused by the
running off of the track or derailment of trains.
Parts of the construction are carried by the car trucks, the other parts forming
an improvement upon the track.

Referring to the drawings:-
1 indicates an ordinary railway car truck, one-half of saine being shown in the
accompanying illustrations, as having a portion 2 of my improvement applied
thereto.
It will be necessary for me to give a brief description of the construction of
the car truck in order that the application of my invention thereto will be readily
understood.
The axles 3 aro provided upon their outor ends projecting boyond the wheels 4
with vertically adjustable journal boxes 5 which are secured to a depending casing 6,
said casing 6 being bolted upon a horizontal truck beam, 7, the application being
similar upon both axles.
The two axles upon each side of the truck are held together by a bracė-bcam 8,
between which and the lower side of the truck-beam 7 are located the springs 9
upon which the car-body rides.
My attachment 2 is located outwardly from and intermediate of two springs 9,
aud is suspended below the beam 7 by vertical braces 10 projecting upwardly from
each end of the hack plate 11 of the attachment, said arnis 10 and back 11, being
internal

page_text: Looking downwardly upon the top of the attachment 2 we see that the back 11
has two outwardly projecting end-plates 12 forming together with said back 11, a
three-sided casing for other parts.
Adapted to fit within the projecting sides 12 is an elongated rectangular shaped
three-sided frame 13, the sides 14 of which normally rest between said sides 12.
The frame 13 is held in a stationary position by angle-braces 15 bolted to its sides
near the outer end plate 15 and bolted to the journal-frame 6.
The frame 13 is held within the sides 12 by a bolt 17 passing through sides 14
and 12 and held by a nut 18 upon one end.
Mounted upon said holt 17 and projecting outwardly therefrom and between the
inner sides of the side-plates 14 of the frame 13 is a cam plate 19, which is provided
with a longitudinal rounded portion upon one edge, having an opening through
which said bolt 17 passes, the plate portion 19 projecting outwardly from said
rounded portion 20.
The forward plate 16 of the frame 13 is provided with a horizontal opening 21
running from the two side-plates 14 and through which are adapted to project two
perforated plates 22 upon a casting 23 which operates within the frame 13. The
casting 23 when viewed from the top looks like a small letter "h," a plato 24 of
which forms one side of the complete casting and is of somewhat shorter length
than the side 14 of the frame 13, against the inner surface of which it is adapted
to operate.
Intermediate of the length of said plate 24 and projecting at right angles there-
with is a plate 25, which has a projecting plate 26 at right angles with the plate 25
and in parallel with the plate 24 and which extends outwardly the same distance as
Faid plate 24, the two projections 22 connecting said plates 24 and 26 and projecting
outwardly horizontally therefrom.
Horizontally mounted between the plates 22 and held in position by a bolt. 27
through the perforations 28 in said plates, is a friction-roller 29 having an anoular
projecting flange 30 around the lower edge of the periphery.
A horizontal shaft 31 is provided adjacent one end with a thick collar 32 said
end 33 being screw-threaded and adapted to bo secured in an opening in the
near plate 11 and held therein by a nut 34 screwed upon the ends of said shaft 31.
The opposite end of the shaft 31 projects through a slot 35, in the plate 25
and hetween said plate 25 and the plato 11 upon said shaft 31 is located a coil
tension spring 36, the normal tendency of which is to keep the entire casting 23
and accompanying parts outward, the limit being determined by the contact of the
edges 37 of the plates 24 and 26 against the end 10 of the frame 13.
Referring particularly to Fig. 4 it will be seen that the plate 24 is provided with
a horizontal opening 38 in alignment with the cam-plate 19 which is provided with
a rectangular cut out portion 30 upon one end to engage in said opening and the
end thoreof.
The edge of the notched or cut out portion 39 limits the rear movement of the
entire casting 23, such an action or movement compressing the spring 36, and a
downward movement of said casting 23 and accompanying parts is attained by the
connection with the cam-plate 19 and the plate 24, the upper and lower edges of
the opening 38 determining the length of the upward or downward movement, as
will be more fully hereinafter described.
It will now bo necessary to describe the construction of the guides forming the
improvement to the track and which is necessary for the operation of the truck
attachment.
The guide 40 comprises a longitudinal strip having an annular projection, which
the wheel 29 is adapted to engage. The track 40 is secured in alignment above
the truck to a vertical standard 41 which projects upwardly at the end of a
horizontal tie strip 42, which is suitably secured in the road bed and upon which
the rails 43 are secured as shown in Fig. 8.
As before stated the truck attachment 2 is located upon both sides of both
trucks' and it is therefore necessary to provide a guide for each side of the track,

page_text: and the opposite end of the metallic tie strip 42 has a similar standard 41 to which
a guide strip 40 is secured.
In case two or more tracks run in alignment, the standards are bolted together
as shown in Fig. 2.
If it is preferred to use the ordinary wooden tie such as is indicated in Fig. 8 by
the numeral 44, it is necessary to provide an attachment 45 which consists of a Yor
fork-shaped plate 46 having a vertical standard 47 upon one and to which tho
guide 40 is secured. The arms 47 of the plate 46 are bent downwardly and upon
each side of the wooden tie 44 said plate 46 being secured to the upper side of the
tie as shown in Fig. 2.
The car in travelling along has four wheels such as 29 engaging under the guide
strips 40 upon each side by the means of the flange 31 upon said wheels 29.
The engagement of the flanges 30 under the guides 40 prevents the derailment of
the car, and the engagement of the same wheels by their peripheries with the edges
of said guides prevents any side movement of the car.
In order that the car will pass around curves the horizontal rearward spring
movement of the rollers 20 is provided and controlled by the spring 36 and in the
case of any inequalities in the track or obstructions thereon, the tilting movement
of the roller 29 upon the cam-plate 19 is provided, this movement also being
controlled to a certain extent by the spring 36.
Other forms of supporting ties and standards, different forms of the wheels and
guides, and a different location of the truck or car attachment 2, can be had
without materially affecting the scope of my invention.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what I
