These and various other important objects and
advantages of the invention will become apparent
20 to the reader of the following speci?cation.

has the elongated plate i3rsecured to the top
thereof and into this plate I3 can be driven the
threaded studs or screws 14, these studs or 15
screws passing through the slot I5 01’ the shank
iii of the yoke I‘? in which the pulley I8 is
mounted. Obviously, by loosening and tighten
.ing these studs or screws Hi the shank Hi can be
adjusted on the plate l3 for regulating the
tautness of the cable I!) which is trained over
the pulleys ll-—l8.

Referring to the drawings wherein like numer
It will be observed in Figure 11 that each of
the pulleys‘ is provided with an anti-slipping
cover 20, preferably of rubber, so that the ovate 25
shaped enlargements 2l—22 on the cable l9 can
easily pass thereover. These enlargements 2 l-22
are at substantially diametrically opposite points '
on the cable.
Numeral 23 generally refers to the mail recep 30
tacle which‘ is an elongated rectangular-shaped
box 24 open at each end and provided with a
hinged closure 25 at each end adapted to be
held in closed position by suitable spring latch

showing one of the‘ enlargements thereon.
and this includes apulley ll onthe driven shaft
Obviously, the mailman uses one of
these closures in gaining access to the box 24,
while the person receiving the mail uses the other
closure in gaining access to the box for retrieving
the mail.
A U-shaped member 2'! is secured to the top
of the box 24 and has eyes at the upper ends
of its leg portions denoted by numeral 28 to
which the ends of the cable are secured as at 29.
A pair of strap members 30-30 extend up
wardly from each side of the box 24 and converge 45.
over the box and then further extend upwardly
as at 3!. Each of these portions Si is equipped
with a roller wheel 32 for riding engagement on
the horizontal ?anges 33 of the inverted T-beam 50
34. (See Figure 4.)
As shown in Figure 2, each post ‘I has a U
shaped framework 35 secured by its end portions
to the posts as at 36.
Inside of the frame 35 is the small square 55
frame 31 an upstanding shank 38 of which is se
cured as at 39 to the upper leg of the frame 35,
while the depending shank 40 has the straps a—a
thereof spread apart as at b to straddle the up
standing ?ange of the beam 34 where it is secured
as at 42 to the beam, thus suspending the beam
in a substantially horizontal position as shown
in Figure 1. The mail receptacle 23 is supported
on the thus supported track as suggested in
10 Figure 2.
The drive means consists of the box-like struc
ture 44 through the end portions of which the
driven shaft I2 is journaled.
Upon the platform 9 is mounted the electric
15 motor 45 the armature shaft 46 of which is con
nectible with the driven shaft 12 by the clutch
generally referred to by numeral 41. This clutch
41 is provided with the collar 48 with whichthe
yoke 49 is engaged; this yoke depending from the
20 slide bar 50 which is slidable through the guides
5I—5! on the box 44.
A horizontal rockable arm 52 is pivotally mount
ed on the post 53 and has a laterally disposed por
tion 54 at one end to avoid the pulley II. This
25 lateral portion 54 is provided with the slotted
?nger 55 through which the cable I9 extends.
The remaining end of the arm 52 is provided
with the cam 55 abutting against the plate 5'!
on the adjacent end of the slide bar 50.
Switches 58—59 are provided on the dielectric
panel 60 and these have the arms (SI-62, respec
the motor and connect the clutch 41, while in its
reverse movement the cam 56 releases the plate 5‘!
to disconnect the clutch and open the motor cir
cuit simultaneously.
Thus the box 23 is stopped automatically at the
end of the trackway 24.
It can be seen in Figures 2 and 3 that guide
means is provided for the cable, guide rollers 63
for the upper ?ight of the cable, while an elon
gated roller 64 is mounted on the lower leg of
each frame 35 for guiding the lower ?ight of
the cable l9.
, While the foregoing speci?cation sets forth the
invention in speci?c terms, it is to be understood
that numerous changes in the shape, size and ma 15
terials may be resorted to without departing from
the spirit and scope of the invention as claimed
Having described the invention what is claimed
as new is:
An article carrier of the character described
comprising an endless cable, drive means for said
cable, spaced pulleys over which the cable is
trained, supporting means for said pulleys, a post,
a trackway supported by the post, a receptacle 25
attached to the cable and mounted for longi
tudinal movement on the trackway, a frame-like
structure on the post through which the recep
tacle is movable, said frame-like structure being
provided with a depending portion supporting 30
tively, rising therefrom and in the path of the
the trackway, said depending portion provided
with a loop-like structure, said loop-like struc
arm 52. These switches 58—59 are for the motor
45 which is reversely wound so that as the en
ture serving as a guide for one ?ight of the
largement 2! or 22 strikes the portion 55 of the
arm 52, for operating one of the switches to start
cable, and anti-frictional means in the said loop
like structure for said cable.
