said carriage may perform the desired func-
tion to either raise the rail section A upon
the platform 1 or deposit it upon the ground
beyond the front of the platform, or vice
5 versa. In order to properly support the
said rail section A the depending ends of the
respective pairs of arms 18 have mounted
therein the pulleys 20 and 21 respectively,
through which are adapted to pass two ropes
10 or cables 22 and 23, which are connected to-
gether beyond the pulley 20 to the single
cable 27 operably connected upon the drum
28 of the hoisting apparatus B, the lower
ends of the respective cables 22 and 23 being
15 provided with the rings 24, each one of
which is provided with the two chains 25
carrying at their terminals the hooks 26 for
engagement with the rails of the rail section
A, as clearly shown in Fig. 3 of the draw-
20 ings. It will thus be seen that the hoisting
device may be operated to simultaneously
actuate both of the cables 22 and 23 to raise
or lower the track section A and retain the
same in such a position that it will be par-
25 allel with the underside of the girders 8 and
9 and the top of the platform 1, and so that
when it is desired to lay the sections in con-
tinuity to form a continuous track, said sec-
tions will be projected beyond the end of
3o the car upon the girder 9 and be deposited
in a level position at the desired place, thus
making it possible to lay a section of the
track at a time, and when desired to remove
a section at a time. It will thus be seen that
35 the cable 27 may be used not only as a means
for raising and lowering the rail sections A,
but it may also be employed as what is
termed a " haul in line " to haul the carriage
inwardly from the section 9 upon the sec-
40 tion 8 of the supporting track, but in order
to haul the same outwardly, the cable 29 is
employed it being operably connected to the
hoisting drum 30 of the hoisting apparatus
B and passes upwardly and over the pulley
45 31 connected at the upper end of the sup-
port 2 within the apex thereof and extends
centrally and longitudinally of the machine
and around the enlarged pulley or sheave 32
disposed in the extreme end of the section 9,
50 the terminal of the said cable 29 being con-
nected at 33 to the end of the carriage 19,
thus providing a means whereby the drum
30 is operated to haul the carriage toward
the girder or track 9 or providing what is
55 termed a "haul out line."
It is often desired to. release the strain
upon the cables 22 and 23 when the carriage
is hauled out or in and carries a rail section
and in order to accomplish this, the two
60 members 34 and 35 respectively, are pivoted
to the underside of the carriage 19 as clearly.
shown in Figs. 1 and 3 and have their de-
pending ends b disposed so as to engage the
respective rings 24 theeby to relieve the
65 strain upon the cables 22 and 23 which carrythe weight of the rail sections, engaging said
rings 24, and in order that said hooks may
be released from the rings 24, or be caused
to engage the same simultaneously, the up-
per ends 36 and 37 of the respective pivoted 70
hooks, are connected by means of the cables
37', the cable 38 being connected to the up-
per end 36 of the hook and has its free end
passing over the clamping device 39 mount-
ed upon one of the standards or supports 3, 75
thus providing a means for retaining the
cable 38 in the desired position.
Although no means has been shown for
operably connecting the hoisting device to
propel the car or truck the same may be 80
applied without departing from the spirit
of the invention, it being clearly evident
that the hoisting device may be used as a
propelling power as well as operating means
for the carriage 19. 85
From the foregoing description, it is evi-
dent that the supports 3 and 4, combined
with the girder 8, provide a rigid framework
that is carried by the platform 1, thus pro-
viding means for properly supporting the 90
carriage 19 and the hoisting cables so that
the rail section may be properly moved to
and from the platform 1 and longitudinally
thereof upon the section 9 of the girder 8,
said section being so disposed as to be placed 95
in longitudinal alinement therewith when
desired, and to be folded backwardly upon
the upper portion of the super-structure or
frame when not in use, the same being sup-
ported by means of the inclined supports 12 100
and 13, thus taking the weight from the
free end thereof directly upon the frame-
work and at the same time holding it at such
an incline that it may be readily moved
from such position to the extended position 105
as shown in Figs. 1 and 2.
What is claimed is:
1. The combination with a portable plat-
form, of a framework carried thereby, an I-
beam disposed longitudinally and centrally 110
of the said platform in the framework, an-
other I-beam hingedly connected to the
framework and disposed to aline with and
form a continuous beam with the first men-
tioned I-beam, a hoisting carriage disposed 115
for movement upon said beams, and means
mounted upon the platform for operating
the hoisting carriage.
2. The combination With a portable plat-
form, of a framework carried thereby, two 120
I-beams one of them rigidly connected to
said framework and the other hingedly con-
nected to form a continuous beam with the
stationary beam, a hoisting carriage dis-
posed for travel upon said beams, a pair of 125
flexible cables disposed upon said carriage
and each provided with engaging devices at
their lower ends, a hoisting apparatus
mounted upon the platform, a single cable
attached to both of said cables and to the 10
