The “Addressograph” and similar machines are
designed to print from successive plates carrying
a series of ‘addresses and to print or impress the
addresses which are on the successive plates upon
a similar series of envelopes, letter-heads, etc.
At each operation of the press, one article is
20 printed and the plate which carries the address
is removed from printing position and the suc
' cessive plate is moved into printing position.
My invention has to do with providing a feed-.
ing mechanism so related to the vpress that it
will operate automatically in relation thereto to
remove the printed article and feed another blank
into printing position while the press is operating
to remove the used plate and place the successive
plate in printing'position.

the invention and two modi?cations thereof, such
disclosed‘ arrangements, however, constituting
merely illustrations of the various applications
of the principleof the invention, which will read
ily suggest themselves to one skilled in the art.
The invention will be more readily understood
55 by reference to said drawings, in which:-,
head with a sourceof power such as an electric 45
motor 25 mounted on the frame. of. the machine.
The head 22 projects forward as shown in Fig.
1 and has a depending impression part‘ 21 at its
forward end which is arranged above an opening
28 in the top plate 2|. The printing machine is 50
provided with suitable mechanism operated in,
time with the up and down- movements of the.
impression head 21 and adapted tomove a print
ing plate from a suitable stack, indicated at 29,
arranged at the rear of‘ the machine to a print- 55
ing position below the opening 28 and after the
impression has been made to remove the used
plate and place a successive plate in printing
position. An inked tape, not shown, is arranged
to lie on top of the printing plate and beneath
the head 21.
I '
The feeding mechanism is arranged to feed
articles, such as envelopes, indicated at 23 where
they are supported in a stack in a guide trough
10 30 to a position between the impression head 21
and the printing plate below-same and above the
printing tape, and vto remove the printed article
from such position to a receptacle arranged be
low the holder 33 as indicated at 3!, in which
$11118 printed articles are stored in .a stack as
s own.
Power is supplied to operate the printing ma- ,
chine from any suitablesouree such as an elec
tric motor 23 mounted on the frame of the ma
20 chine and connected ‘through suitable speed re
ducing mechanism indicated at 33 to a depending
arm 34 rigid with the head 22. Power to operate
the feeder is derived from the same source part
ly through the shaft 23 upon which the head 22
25 is mounted, and partly through the speed reduc

33 and sp‘aced from the roller 35 .just su?icient
to allow one envelopeat a time to pass. The
‘roller 52 is carried on a shaft 52' and is held
against rotation thereon. The separator roll 35
and the roller “constitute a calipering means
for controlling the feed of the articles such as
envelopes from the stack 26.
As this separating mechanism per se, is not a.
part of the present invention, it is not thought 10
necessary to describe it more speci?cally except
to say that the calipering means is pivotally
mounted to swing up and down slightly and is
counterbalanced by a weight 53 adiustably
mounted on an arm 54 rigidly mounted on one 15
" of the bell-cranks 38.
The envelopes to be printed when placed in
the inclined trough 30, slide down some towards
the caliper rolls 35 and 52 and the lower end of‘
the forward envelope contacts with the feed roll 20
33 and when the same is rotated to feed the‘
envelope the lower end of the envelope enters in
between the rolls 35 and 52 and is fed forward

out of printing position, a pulley to which one
end of the tape is secured for moving the tape
in one direction, a segmental gear and a co-oper
ating' pinion for intermittently rotating, said
pulley, and latch means for connecting the pinion
to the pulley for rotating same.
2. The invention de?ned in claim 1, and means
for unlatching the pinion from the pulley at one V40
end of its movement, and means for automati
cally closing the latch at the opposite end of
the movement. _
3. In a mechanism of the kind described, a re

The slide guide I10 is provided with a longi
tudinally extending opening I13 on its under
55 side'and through‘. which a post I14, rigid with
the slide member. I69, projects downwardly.
_ This post' is connected by "a horizontal link
I15 with a long arm I16 of a bell-crank I11,
which has a short arm I18 by which the bell
60 crank is adapted to be swung on its pivot I19.
The pivot I19 is mounted‘ in the free end of a
' ‘?at projection I80 extending out from the side
of the slide guide I10.
For swinging the bell-crank I11 back and forth
and through the bell-crank moving the slide I69
back and forth, the free end of the short arm
I18 of the bell-crank I11 is connected by a rod
I8I with a projection I82‘ extending out rigidly
from the side of the impr‘esison‘v member 22 of the
printing machine. As explained before, the
