4 Claims. (cl. 258-2)
My invention relates to improvements in ap
hoops Ill connected together at spaced intervals
paratus for delivering train-orders and the like. by clamps I l and in turn the hoops are rigidly se
It is an object of the invention to provide a cured to the staff ‘members by clamps l2. A tu
train-order delivering device for successively de
bular arm I3 is pivotally attached to a collar I 4,
‘ 5 livering a plurality of orders to the engineers’ by the pivot pin IS, the collar being clamped to 5
and conductor of a moving train.
A further object of the invention is to provide
a plurality of train-order holders arranged‘ to
successively swing into position along the path of
'10 a moving train and having tripping mechanism
for releasing the holder operable upon removal
of the train-order.
Another object of the invention is to provide
apparatus of the above-mentioned character
15 which is simple and durable in construction, re
liable and ei?cient in operation and inexpensive
to manufacture.
.
Other objects and advantages of the invention
will be apparent during the course of the follow
20 ing description.

In the accompanying drawings, forming a part
of this speci?cation and in which like numerals
are employed to designate like parts throughout
the same,
the member of the staff in the center of the hoops,
so that the arm 13 extends diametrically across
and between the hoops, projecting at both ends
beyond the periphery thereof. The center of the
arm I 3 is provided with a Y coupling I 6 from 10‘
which extends an auxiliary arm I1 extending in
diverging relation to the main arm between and
beyond the peripheries of the hoops.
The train order holders consist of a tube l8
adapted to telescopically ?t within the ends of 15
the’ arms I3 and I1 and removably secured there
in by means of the spring pressed latch bolt l8’
attached to the outside'of the arm. The bolt
I8’ is slidably mounted in the casing l9 and ex
tends through an opening 20 in the arm. . A 20
spring 2| mounted on the bolt and having one end
engaged with the transverse pin 22 extending
through the bolt, normally forces the bolt in

pivotally mounted for swinging movement into
and out of the openings.
These catches are
positioned for engagement by the cross bar 34, to
support the arms l3 and I‘! in an operative posi
5 tion. The free end of arm I3 is equipped with a
pull chain 38 for swinging the arm into operative
_position. A platform 39 is attached to the mem
ber 6 of the staff 5 and has a ladder 40 leading
therefrom to the ground, so that the holders may
10 be readily placed in and removed from the sup
porting arms.
In operation, the order holding loop 30 is at
tached to the holder which holds the movable bar
21 of the holder in a raised position and upon in
15 sertion of the tube I8 of the holder in the arm l3
or [1, the cross bar 34 will be in frictional contact
with the peripheries of the guide hoops l0 and
upon swinging of the arm l3 to an operative
position, the cross bar will engage the catches 31
20 which will support the arm IS in position for de
livering the train order to the crew of the train.
‘Upon removal of the holding loop 30, the movable
bar 21 will drop downwardly and through the
bell crank lever 25 and rod 32 will move the cross
25 bar 34 forwardly, out of engagement with the
catches 31, so that the arm I3 is free to swing
downwardly. When each of the arms l3 and II
are supporting holders, it will be seen that as the
arm l3 swings downwardly, the arm II. will be
30 moved to an operative position, in which position
it will be supported by the catches 31 engaging the
cross bar 34 of the holder. Thus, it is seen that
when it is desired to deliver a plurality of orders
to different members of the train crew, the appa
35 ratus will successively deliver the orders to the
train crew as the train passes by.
It is to be understood that the form of my in
vention herewith shown and described is to be
taken as a preferred example of the same and
40 that certain changes in the shape, size and ar
rangement of the parts may be made without
departing from the spirit of the invention or the
scope of the subjoined claims.
Having thus described my invention, I claim:
