standards 1, said ladder extending to the
platform 13; and bearing downwardly on
the end of the arm 7 until it assumes an
approximately horizontal position, the hook
5 15 is then engaged over an elongated pro-
jection 17 on the side of said arm. As will
be noted from the drawings the arm 7 has
a screw-eye 18 near its outer end through
which the rope 5 passes, and said rope is
10 of sufficient length to permit the arm to
assume its horizontal and vertical positions.
The grabbing hook 11 is then adjusted so
as to present its open portion toward the
direction in which the train is to come and
i5 the .hook 15 on the same side of the arm 7
as this direction is used when adjusting the
arm in its operative position. The appa-
ratus requires no further attention on the
part of the operator until such time as it
20 is convenient for him to remove the con-
tents of the receptacle.
The car carrying the mail is provided
with a swinging crane 19 comprising spaced
horizontal arms 20 between which the bag
25 or pouch of mail 21 is removably suspended.
Said pouch 21 is tied preferably at its cen-
tral portion and in passing my apparatus
the contracted portion is engaged in the
hook 11, the jar imparted by the action de-
co sribed disengaging the retaining hook 15
from the arm 7, whereupon the bag, by rea-
son of the mounting of said arm and the
weight 10 on the opposite end thereof, is
swung and deposited in the receptacle 2, the
35 arm 7 moving through the slot 6 in the bot-
tom of said receptacle.
Through the instrumentality of the rope
5 which is attached to the arm, the doors 4
are pulled shut and being preferably pro-
40 vided with a lock 22 the receptacle is thus
closed against unauthorized access.
A spring 23 secured to the side of the re-
ceptacle 2 engages with an eye on the doors
4 to hold them from being swung by the
45 wind, but will readily permit disengage-
ment when the arm is forced upwardly and
the rope 5 draws them into closed position.
The mounting of the hook 11 will permit
the same to be turned, from its horizontal
so plane.by the weight of the bag as it is swung
into the receptacle 2 and will assume a po-
sition in a vertical plane, as clearly shown
in dotted lines in Fig. 3 of the drawings, so
that said bag is released from the hook and
55 deposited in the receptacle.
.Having thus described the invention,
what is claimed as new is:
1. A mail bag receiving apparatus com-
prising. a receptacle, a pivoted receiving
60 member, a trigger coperating with one end
of the receiving member to engage and hold
said member in an abnormal position to
catch the bag and operable by impact of the
bag with the receiving member to disen-
65 gage the trigger from the latter, and aweight carried on the other end of the mem-
ber. to move the receiving member when re-
leased to carry the bag into the receptacle.
2. A mail bag receiving apparatus, com-
prising .standards, a receptacle carried by 70
said standards, doors for said receptacle, an
arm mounted on the standards adapted to re-
move a bag from a moving train, means to
permit the arm to deliver the bag into the
receptacle when actuated, a~nd means co- 75
operating with said arm to automatically
close the doors aforesaid as the bag is de-
posited in the receptacle.
3. A mail bag receiving apparatus, com-
prising standards, a receptacle mounted 80
thereon, doors for said receptacle, an arm
I pivotally mounted beneath the receptacle, a
connection between the doors aforesaid and
the arm operable to close the doors when
the arm is actuated, and means to hold the s5
arm in operative position and adapted to be
released by contact of the bag with said arm.
4. A mail bag receiving apparatus, com-
prising standards, a receptacle carried
thereby, doors for said receptacle, means for 90
catching a bag from a moving train, de-
livering the bag into said receptacle and si-
multaneously closing the doors aforesaid.
5. A mail bag receiving apparatus, com-
prising standards, a receptacle carried there- 95
by, doors for said receptacle, an arm pivot-
ally mounted on the standards having means
normally tending to cause the arm to assume
a vertical position, means for holding the
-arm in operative position to receive a bag noo
from a moving train, means connecting the
doors and arm aforesaid normally .inactive
when the latter is in operative position and
operable to close the doors when the arm is
actuated, and means on the arm to catch the 105
bag and operable by said bag to permit its
deposit into the receptacle when the -arm is
swung thereinto.
6. A mail bag receiving apparatus, com-
prising standards, a receptacle carriedthere- 110
by, doors for said receptacle, an arm piv-
otally mounted beneath said receptacle and
having means normally tending to cause the
arm to assume a vertical position, a retain-
ing hook to hold the arm in approximately 115
horizontal operative position to receive a
bag from a moving train, and operable by
contact of the bag to release the arm and
permit it to be swung into the receptacle, a
flexible connection between the doorsafore- 120
said and connected to the arm, and a grab-
bing hook mounted on one end of said arni
to catch the bag and deposit the same into
the receptacle.
7. A mail bag receiving apparatus, com- 125
prising standards, a receptacle carried there-
by, doors for said receptacle, an arm pivot-
ally mounted beneath' said receptacle, hav-
ing means normally tending to cause the
arm to swing thereinto, a platform secured i cS
