ing on the pins 13. The seat 7 may be made
to descend into the body or casing by pull-
ing on a lever 14 which is fulcrumed on one
of the slides 10. A link bar 15 is pivotally
5 connected to the lever 14 and pivotally con-
nected to a bell crank lever 16 which is ful-
crumed on the slide 10 with the lever 14.
The lever 16 is pivotally connected to the
jointed pin 13. Both slides 10 may be pro-
10 vided with levers 16 and pins 13 if necessary.
A pull on the lever 14 will let the seat 7 drop
to the position of the dotted outline in Fig. 2.
The carrier is provided with a lid 17
which is attached to the T-irons 9. See Fig.
15 2. Bars 18 connect the T-irons 9 with the
shell of the lid and the lid 17 can be at-
tached to the T-irons 9 in any other suitable
manner. The lid cannot be closed until the
seat descends into the carrier 1, but as soon
20 as the slides 10 pass down off the T-irons 9,
the lid is free to fall. In order to make a
positive throw for the lid, a lug 19 is at-
tached to the lid and a spring 20 is attached
to a bracket 21 which is to be attached to a
25 convenient part of the cab. The spring 20
stands compressed against the lug 19 and as
soon as the seat releases the lid, it will fall,
being started by the spring 20. The safety
device is mounted in the cab by hinged bands
30 or hoops 22 which are attached to the en-
gine frame in any suitable manner. The
bands are brought together and held in op-
erative position by pins 23, the bands having
interlocking joints to receive the pins 23.
35 Wire cables or cords 24 and 25 are connected
to the pins 23 and connected to the lid 17 so
that when the lid falls, the pins 23 will be
drawn from the joints of the bands 22 and
thus release the bands 22 from the carrier.
40 Additional mounting devices for the carrier
consist of hanger rods 26 which are at-
tached to the timbers of the cab and hang
down by the casing or shell 1. The lower
ends of the hangers 26 have holes to receive
45 supporting pins 27 which are held normally
projected through the shell 1 into the hang-
ers 26 by springs 28. The pins 27 are pro-
vided with guides 29 and are automatically
withdrawn from the hangers 26 when the
50 lid falls. The pins 27 are attached to a flexi-
ble cord 30 and a cavity 31 is formed in the
weighted portion 3 of the carrier. A buffer
32 is attached to the bottom of the seat 7.
When the seat falls the buffer 32 will strike
55 the cord 30 and force the same downwardly
(see Fig. 2) to the position of the dotted out-
line. This action will draw the pins 27 out
of the hangers 26 and thus release the car-
rier from the hangers. The hoops or bands
60 22 are connected by interlocking joints in
front as well as on the back. The interlock-
ing joint is released at the same time the in-
terlocking joint in the rear is released by the
cables 24 and 25. The interlocking joint in
65 front is held locked by a pin 33. A bar 34 ismounted in guides 35 to move freely through
these guides. The bar 34 carries lugs 36
adapted to strike the pins 33. When the lid
falls it will strike the bar 34 and the lugs
36 will knock the pins 33 out of the inter- 70
locking joints and thus release the bands or
hoops 22. The pins 23 will be released
slightly before the pins 33, but the pins 33
and the pins 27 will be released simultane-
ously so that the carrier will fall out of the 7
engine cab. The seat 7 is mounted on the
slides 10 and is provided with cushion
springs 37 which are supported on vertical
bars 38 which rest on the platform 39. A
shield 40 is made rigid with the platform to go
protect the elements behind the shield. In
addition to the braces for the seat heretofore
noted, the seat is braced by the bars 18 which
are connected to the lid and to the T-irons 9.
Means are provided for locking the lid in a s
closed position. A catch 42 is rigid with
the interior of the casing and a spring catch
or lock 43 is attached to the lid. When the
lid falls the lock 43 will catch in the catch
42. The lock 43 is.in the form of a bell a.
crank lever and a spring 44 normally holds
the lock in the locking position, but the per-
son inside can open the lid by pressing on
the back end of the lever. A person on the
outside can open the lid by taking out the z;
screw 45 which mounts the spring and thus
displace the spring so that the device can be
unlocked.
When the carrier starts out of the engi-
neer's cab, swinging rods 46 are used to 100
shift the lower part of the carrier out to-
ward the side so that the carrier will not fall
directly in the railway track. The rods 46
are pivotally connected to some part of the
cab and are provided with yokes 47 which soy
engage lugs 48 on the side of the carrier.
The safety device herein described has
been set forth for the use of the engineer.
It is apparent that the device is also adapt-
ed for the use of the fireman and other 11 ta
workmen on moving trains or other devices.
The lid 7 is provided with a valve 49
hingedly connected to the lid and normally
closing an opening which can be used to
obtain fresh air. The valve may be oper- 115
ated by a rope or cord 50.
Instead of hinging the lid 7 to the T-
irons, as heretofore set forth, the lid may be
hinged to the shell 1, as shown in Figs.
8-12. 120
The variations shown in Figs. 13-20
comprise a safety device for the same pur-
pose as the device previously described and
similar in design. The construction varies
from the construction previously described. 125
There is merely a change in the body of the
device. The shell is composed of two parts
51 and 52. The part 51 is the main body
and the part 52 is movable relative to the
part 51 and is adapted to telescope into a 130
