proaching an obstacle and does not wish to
have the brakes applied, he will grasp the
handle 19 and hold it stationary until the
obstacle has been passed and the slide plate
a 8 returned to its normal position.
Any suitable form of obstacle or trip 24
may be employed in connection with my
train stop. For the purpose of illustration,
I have shown one which is pivoted at 25 to
1o the upper side of one of the ties. The ob-
stacle or trip 24 extends over and rests upon
the upper sides of several ties, and it is
adapted to be moved upon its pivot 25 in
the direction of and away from the rail.
15 When moved in. the direction of the rail,
and parallel thereto, the obstacle or trip 24
is in . operative position, and when moved
away from the rail, and diagonally with re-
lation thereto, the obstacle or. trip 24 is in in-
20 operative position. The obstacle or trip 24
may .be moved into operative position by a
station master or agent, and to permit of this
I provide a shaft 26 which is journaled in
bearings 27. The shaft 26 is arranged par-
25 allel with relation to the rail, and it is pro-
vided with a crank 28, a link 29 connecting
the outer end of the crank 28 to the under-
side of the obstacle or trip 24. The shaft 26
may be connected to.any suitable means for
M operation by the station master or agent.
From the foregoing description taken in
connection with the accompanying draw-
ings, it will be apparent that I have pro-
vided a very simple and practical train stop
3 which will automatically operate to stop. a
train should an obstacle in operative posi-
tion be passed without the knowledge of the
engineer.
While I have shown and described the
'- preferred embodiment of my invention, it
will be understood that minor changes in
construction, combination and arrangement
of parts may be made without departing
from the spirit and scope of the invention as
claimed.
Having thus described my invention, I
claim
1. In an automatic stop of the character
described the combination with a locomo-
tive, of a lever pivotally secured thereto in-
termediate its ends, a slide plate, a connec-
tion between the said lever and slide plate,
a weight supported by the slide plate, and
a flexible member connected at one end to
the weight and at its other end to the han-
dle of the engineer's brake valve, said lever
being adapted to engage an obstacle, where-
by the slide plate is withdrawn from under
the weight, allowing the latter to drop.
2. In an automatic stop of the character
described the combination with a locomo-
tive, of a vertical lever pivoted intermediate
its ends thereto, a slide plate horizontally
movable along the underside of the running
board, said board being formed with anopening, a weight positioned within said
opening and resting upon the slide plate, a
flexible member connected at one end: to the
weight and at its other end to the handle of
the engineer's brake valve, a connection be- 71
tween the upper end of the lever and the
slide plate, whereby said plate will be drawn
from i.nder the weight when the lever is ac-
tuated,:and spring means for returning the
plate to its normal position under the open- 75
ing formed in the running board.
3. In a stop of the character described
the combination with a locomotive, of a ver-
tical lever pivoted intermediate its ends
thereto, a slide plate movable upon the un- so
derside of the running board, a connection
between. said. slide plate and lever, spring
means for returning the slide plate to its
normal position when actuated by the lever,
the running board being formed with an 85:
opening, a weight positioned within said
opening and resting upon the slide plate,
a flexible connection secured at one end to
the weight and at the other end to the engi-
neer's brake valve, and guide rollers for 9&
said connection, a dropping of the weight
causing the. valve to be opened, whereby the
airbrakes are applied.
4. In an automatic stop of the character
described, the combination with a locomo- 95
tive, of a vertical casing secured to said lo-
comotive, said casing having an aperture
formed in one side thereof intermediate its
end and a similar aperture formed on the
opposite side adjacent the lower end there- 101
of, a weight slidably mounted in said cas-
ing, a sliding plate extending through the
lower]. aperture and supporting said weight,
a pulley secured to the upper portion of
said casing, a similar pulley secured to one 105
side of said casing adjacent the upper aper-
ture, and a cord having.one end secured to
said weight and passed over the upper pul-
ley and then under the other pulley and
through said adjacent aperture and having 110
its opposite end secured to an air brake valve
for the purpose specified.
5. In an automatic stop of the character
described, the combination with a locomo-
tive, of a vertical casing, a weight slidably 115
mounted in said casing, a cord having one
of its ends secured to said weight and the
opposite end to an air brake valve, a hori-
zontal casing, a plate slidably mounted in
said horizontal casing, said plate adapted 120
to extend into said vertical casing and sup-
port said weight, a rod secured to said plate
and extending outward of said casing; a
spring coiled around said rod having one
end engaging said sliding plate and the op- 125
posite end engaging said casing to normally
hold said sliding plate into said vertical
casing, and means secured to the free end
of said rod to move said sliding plate
against the tension of the spring. 1300
