their Contents.
DANIEL ISSAC BETTISS of 41 Farraday Road Leyton Essex Shunter in the
employ of the Great Eastern Railway do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Two doors fixed in square frame the frame to be fixed in the middle of the box
by a peice of iron or other metal comeing down from the four corners of the
frame so that a bolt or a screw can be put through each peice and so makeing
the frame fast to the box the two doors to be fixeed to the frame by hinges
one door fixeed to the front of frame and the other door to the back of frame the
front of frame to be which ever way the hole is in the box so that the doors
are crossways of the frame the door in the back of the frame to be made longer
than the one in the front of frame so that when they are shut it laps halfway over
the bottom of the door in front of frame the frame to be made as large as the inside
of the box where it is intended to put the improvements in two corner posts made
fast to the two front corners of the frame run up as high as the top of the hole in
the box and are strengthened in that position by a peice of iron or other metal
made fast to each side of the frame and comeing halfway up the posts and made
fast to them so as to hold the posts firm when the flap is moved spindle and flap
from one post to the other flap being downwards over the hole in the box the flap to
be made large enough so as to cover the inside of the hole in the box and made fast
to the spindle two levers one from each end of the spindle come halfway over above
the doors and made fast to the spindle close up to the inside of the posts the
spindle to be put in the posts so it will turn when the flap is moved two rods come
down from each lever and fasten onto doors in the frame below the rods to be
fastened to the levers and doors by hinges so as to move when the levers move a
slide fixeed from one post to the other comes down towards the doors in the frame
below the slide to be fixed about three parts of the way up the posts so as when

page_text: the flap is pushed up to put a letter in the box it moves the spindle and as the
spindle turns it pulls the two levers up the levers pulling the four rods up and the
rods pulling the doors up and shuting them so as the bottom half of the box is shut
off the letter when put in slides down the slide and falls on to the doors below and
remains there till the flap is let go of as soon as the flap is at liberty it goes into its
former place spindle turns back again levers and rods go into their former places
doors open and the letter falls to the bottom of the box spindle and flap levers rods
and doors remain so till the flap is moved again when they work as described and
in order that my said invention may be clearly understood reference is hereby made
to the accompanying drawing.
Figure 1 represents the improvements made already to be placed in the box with
the doors open and the flap downwards which will be over the inside of the hole in
the box when the improvements are fixeed in a. is the square frame b. is the door
in the front of frame . is the door in the back of frame dande are the two corner
posts f. and g. are the peices of iron or other metal to strengthen them . is the
spindle i. is the flap and k. are the two levers 1. m. n. and o. are the four rods
that come from levers to doors p. is the slide that comes from the posts towards
the doors in the frame below the improvements to be made with iron or other metal
suitable.
Haveing now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
claim is.
1. The frame and doors.
2. The corner posts and the peices of iron or other metal to strengthen them.
3. The spindle, flap and levers.
