Improvements in Means or Apparatus for Use in Addressing
Envelopes, Post Cards, Wrappers, and the like.
I, FRANK DRAYTON BELKNAP, of 314-316 Broadway, New York City,
United States of America, Publisher of Trade Lists, do hereby declare the nature
of this invention to be as follows:-
My invention relates to what are known as addressing machines. That is
machines by which a number of envelopes postal cards, newspaper wrappers, or
other articles can be printed each with one name from a long list of such names
and addresses, and mailed accordingly. It is specifically designed to apply to that
class of addressing machines in which nou-metallic stencils are used. These stencils
have heretofore commonly been used in the shape of long rolls of parchment or
similar suitable material upon which have been written the names and addresses by
means of perforations through said parchment. As frequent corrections, additions
and erasures are necessary in any such list, it has been a matter of great difficulty
to make these changes on such a roll and still preserve the alphabetical order or
other classification of the names. To overcome this difficulty, I propose to
substitute for the parchment roll a set of small non-metallic perforated stencil
cards which can be packed in a magazine like cards of a card catalogue, and easily
removed or added to.
My present invention consists of a simple machine specifically designed to use
such card stencils in the addressing of envelopes, etc. together with a specific form
of Don-metallic stencil card to be employed therewith. The machine and card are
illustrated in the accompanying seven sheets of drawings, in which
Fig. 1, is a side view of the machine.
Fig. 2, is a longitudinal section.

the printing mechanism.
Fig. 13, is a longitudinal section of a third form of machine embodying my
invention.

mechanism.
Fig. 58, is a half rear clevation and half cross section of the slide mechanism.
Throughout the drawings, like reference figures refer to like parts.
1, represents the main frame of the machine.
2, is an endless feed band which passes through the printing mechanism, carries
to it the envelopes and card stencil in position for printing, and afterwards delivers
them to suitable receptacles. This feed band runs around pulleys 3, 4, and 5, and
over the driving drum 6. On the band at uniform distances are sets of hooks, 7,
which serve to hold the cards on to the band, during a portion of its travel and
also to properly space them. This endless feed band may be solid, and the
Price d

page_text: printing done over its edges or it may have openings cut in it through which the
printing could be done, but preferably I make it double, composed of the two
parts, 2 and 2 A., as best shown in Figure 3. The two parts then suffice to carry
the cards and articles to be printed while the printing and some of the other feed
mechanism can operate between the two portions of the double band.
8, is a magazine of stencil cards, having its cover thrown back, and when in use
placed upon the bracket 9.
10, is a magazine of envelopes, postal cards or other articles to be printed,
resting on bracket 11. The stencil cards and articles to be printed can be fed out
slowly toward the mouths of their magazines by means of a spiral spring or other
mechanism, not shown.
8", is a magazine for stencil cards being charged or used as a collection box.
This together with 10 A, a similar collection box for the envelopes or printed
articles, stand on the bracket 12, at the delivery end of the machine. The box for
the smaller of the two sets of articles (that is the stencil cards and the envelopes)
is placed next to the machine with its mouth just at the turning point of the endless
feed band 2. At this point the band goes around roller 3 and changes from a
horizontal to a downward direction of motion. The result is, that the printed
envelope and stencil card are shot down over the mouth 13 of the collection box 8",
which mouth is inclined as shown. The stencil card falls into its collection box
while the larger envelope slides over its mouth and drops into that of its particular
collection box 10%, the mouth of which 14, is inclined is an opposite direction to
prevent the envelope shooting beyond.
It is evident that an intermittent motion should be given to the endless feed band
equal in motion to the distance between any two adjacent sets of hooks, 7. This
is accomplished by means of the ratchet wheel 15, and pawl 16, which together
form a pawl and ratchet motion. The pawl is mounted on the link 17, and is given
a reciprocating motion by the link 18, which is connected to the rotating gear
wheel 19 which is on the main driving shaft 21. The ratchet wheel 15, is of course
keyed to the shaft of the driving drum 6.
The main shaft 21, is driven by the belt pulley 22. Keyed to the main shaft is
the eccentric 23, which by means of the eccentric rod 24, gives a reciprocating
motion to the bell crank 25. This bell-crank operates, through the link 26, the
suction arms 27, which are fitted up with the rubber suction piece 28. I have
shown two of these arms which are mounted on a tubular shaft 43. These arms
move between the two parts of the double feed band as shown in Fig. 3.
29, is another branch of the bell-crank 25, which by means of the link, 30,
operates a similar set of suction arms 31, provided with rubber suction mouths 32,
and mounted on hollow shaft 43 A. These two suction arms operate outside of the
feed band 2, as shown in Fig. 3 and do not interfere with the stencil card which is
lying upon it at that point.
The bell-crank 25, by means of the piston rod 33, and piston 34, also operates
the air pump 35, which is pivoted to the main frame at 36.
37 is a flexible pipe which by means of the branch pipes 38 and 39, is connected
with the hollow tubular shafts 43 and 43 A, respectively. The connection between
the tubular shafts 43 and 43 A, and the pipes 38 and 39, is rendered air-tight by
means of the stuffing boxes 40 and 40 A, as best shown in Fig. 1 and 3.
It is evident without further describing the operation of the machine at this
point that the suction mouths 28, pick up the topmost stencil card 41, and lay it on
the feed band 2, before one of the sets of hooks 7, while the suction mouths 32, will
pick up the first envelope in the magazine 10, and deposit it on said feed band
before another set of hooks, and on top of the stencil card already deposited there
by previous operations of the machine."
It now remains to describe the printing mechanism.
44, is a cam on the main shaft which is full faced through 180 degrees and
partially cut away through the other 180 degrees. This operates the cam roller 45,
which is on the slide connected to the link 46. There are two sets of these cams,

page_text: slides and links, one on either side of the machine, and the links are pivoted to the
cross bar 47 A, of the vibrating platen 47. This platen 47, I have shown pivoted
to the main frame and vibrated by the mechanisin last described, together with the
springs 48, which hold the rollers 45 against the cams 44, and lift the platen 47
during one half of the revolution of the main shaft.
The gear 20, keyed on the shaft 20 A, meshes with the gear 19, on the main
shaft and is driven thereby. The shaft 20 has the cam 50, which by means of the
cam roller 49 A, gives the ink platen 49, a vertical reciprocating motion.
51 is the roller of an ordinary ink fount and 52, is a small inking roller which
normally rests on the shelf 53, which is close beside the platen 49, when in its
lower-most position, and on the opposite side of it from the ink fount. This
inking roller is mounted on the flexible arm 54, pivoted to the lever 55, which is
mounted on the strut 56, bolted to the main frame, as shown in Fig. 2. The
lever 55 has a cam roller 57, on its lower end which runs on the very quick cam 58
also mounted on the shaft 20 A. The spiral spring 59 serves to keep the lever 55,
in such position that its cam roller 57 is against the cam 58, and the inking
roller 52, is normally held over the shelf, 53. The spring 60, serves to force the
link 54 downward, so that said inking roller 52, will not fly up from the shelf 53.
The spring 61, pulls down the reciprocating platen 49, when it is not positively
lifted by the action of the cam 50.
In the modification illustrated in Fig. 7, another inking apparatus is shown, in
which the large bell crank 74, is vibrated by the eccentric cam 75. This bell
crank, 74, carries a number of inking rollers 77, which run from a curved inking
surface 76, which extends over to the ordinary form of ink fount shown in the
other drawings as well. These inking rollers 77, are mounted in longitudinally
sliding links 78, whose inner ends are provided with cam rollers 79, and springs 81.
These cam rollers run over a stationary cam piece 80, which has a central horizontal
portion and an inclined portion on either side.
74 A is a loose inking roller which transmits the ink from the fount to the
surface 76.
The operation of this form of my improved machine is as follows:-
Motion being given to the main shaft 21, by the belt pulley 22, the gear 19 is
rotated and the ratchet gear 16, vibrated so that the driving drum 6, is given a
quarter of a revolution during one half of the revolution of the main shaft, and
allowed to stand at rest the other half. This gives the feed band 2 an intermittent
forward motion, which motion being equal to a quarter of the circumference of
the driving drum 6, or the distance between two adjacent sets of hooks 7. This
revolution of the main shaft, by means of the eccentric 23, and connections causes
the suction arins 27 to be pressed down against the topmost stencil card in the
magazine 8, and at the moment such suction arms start on their backward motion
the piston 34, begins to move out of the air pump 35, and the suction thus created
extending through the pipes 37 and 38, causes the stencil card to adhere to the
suction moutlis 28, and the continued upward motion of the arms 27, brings the
said stencil card against the feed band, 2, and holds it there for a second until
the said feed band begins to move by the proper timing of the mechanism and one
of the sets of books lifts the card 41, away from the suction arms which had held
it up to that moment.
The second revolution of the driving shaft has lifted the stencil card 41, up to
the horizontal portion of the feed band 2, and during such second revolution
the vibrations of the suction arms 31 have, through the agency of the suction
mouths 32, and pipe 39 and pump 35 as before described, brought down an
envelope from the magazine 10 and placed it over the stencil card, as shown
in Fig. 2. Just before the suction mouths 32 let go of the said envelope, the
envelope is wrenched away from it by the motion of the feed band, and hooks, as
before described, and the envelope lying over the stencil card is carried along
toward the printing mechanism.
In the arrangements of parts shown in these figures of the drawings two of the

page_text: intermittent motions of the feed band will carry the envelope and card we are
following under the supporting platen 47. The next rotation of the main shaft
will bring the full portion of the cam 44 against the cam roller 45 and drop down
the supporting platen, 47 upon the envelope. The same motion of the shaft will,
when this has been accomplished, have turned the gear wheel 20, and the cam 50,
far enough to drive up the reciprocating inking platen 49. This will press against
the stencil card and envelope which are backed by the supporting platen, 47, and a
portion of the ink being forced through the perforations of the stencil card the
name and address so perforated will be printed on the envelope.
A complete revolution will have lifted the supporting platen 47, and withdrawn
the inking platen 49. The next motion of the feed band will carry the card and
addressed envelope forward and discharge them. From the edge of the machine
they will drop into their respective collection boxes, as before described. When
these boxes are full they can be removed and empty ones substituted.
The collection box of stencil cards when filled becomes a magazine to be placed
when needed upon bracket 9 and used to feed the machine again.
While the inking platen 49, is at rest, in its lowermost position, as it is about
during one half of the revolution of the cam 50, the quick motion of cam 58,
vibrates the lever 55, and drives the inking roller 52, over and on to the roller 51
of the ink fount, and when the same is withdrawn on the passage of cam 58, it rolls
across the platen 49 and freshly inks it.
The construction of the modification illustrated in Fig. 7 is in every way similar
excepting that the ink in the fount is spread over the curved surface 76, by the
loose roller 77 A and from this surface 76 is picked up by the rollers 77, which are
held down to it by the springs 81 during a major portion of each oscillation of the
bell crank 74. As the rollers 77 come under the stencil card which is held down
by the envelope, and supporting platen back of it, said rollers 77, are raised by
reason of the cam rollers 79, running over the raised portion of the cam 80, and
said rollers are run across the under face of the stencil card, and the ink is forced
through its perforations on to the envelope, as before.
Various changes could be made in the construction of this form of my machine,
without departing from the spirit of my invention.
The
The printing mechanism might be placed above the feed band, and the stencil
placed on top of the envelope which would simply necessitate a reversal of the
positions, of the stencil and envelope magazines and collection boxes.
arrangement of hollow shafts and suction arms could be replaced by a solid
construction with flexible rubber tube extending from the air pump to the suction
mouths on the ends of the arms. The eccentrics might be replaced by cranks, and
cranks in turn by cams if necessary at various points, as is well understood by those
skilled in mechanism.
Referring now to the third form of my invention, illustrated in Figures 1R
to Fig. 5B, inclusive, 1b is the main frame of the machine, 2b is an endless feed band
which preferably is composed of two parts, 2 B and 2 A, as described in the first
part of this Specification, and a large portion of the machine
not herein
specifically described conforms to the construction fully shown and described in
said first part of this Specification. The feed band runs around the pulleys 3b,
4 and 5. The pulley 5 B is driven by the larger pulley 6 B which is keyed on to
its shaft. The pulley 6b is driven by the belt 7b which runs around a smaller
pulley on the main shaft 8.
34 is a series of envelopes, postal cards or other articles which are to be
addressed, placed in a magazine 34°.
32 is a similar series of stencil cards contained in a magazine 30' which rests
upon the table 28, and is prevented from moving horizontally by reason of the
strap 31 encircling the vertical portion of the angle iron 29, which angle iron is
bolted to the said table 28b. Running beneath said table 28b and beneath the
mouth of the magazine 30°, is the reciprocating slide 27 which is mounted in
grooved portions 41" of the main frame of the machine as best shown in Fig. 5³.

page_text: This slide 27 has a raised portion 33 which is equal to or slightly less than the
thickness of one of the stencil cards 32.
The slide 27 should be given a reciprocating motion, and preferably that motion
should be of only moderate rapidity toward the right, but there should be a quick
return motion toward the left. The preferred mechanism for producing this motion,
consists of the cam 19 on the shaft 19 which by means of the reciprocating
link, 21, the cam roller 20 mounted thereon, the retracting spring 22, the
lever 23 pivoted to the main frame at 24, and link 25° and lugs 26' transmits a
slow outward motion and a quick return motion to the slide 27, as will be readily
understood by referring to Fig. 1B of the drawing. The shaft 19 is revolved by
means of a pinion 18b meshing with the pinion 17 on the main shaft 8°.
The envelopes 35 B are fed down one at a time on the endless feed band by means
of the suction fingers 35b, operated by the link 36, bell-crank 37b, eccentric
rod 38°, and eccentric 39b on the shaft 19, as fully described in the first part of
this Specification.
The inking mechanism consists of the reciprocating inking platen 11', operated
by the cam 9b on the main shaft and the retracting spring 16, acting with the
ink-fount 12b, inking roller 13, and connecting lever 14 operated by the cam 15",
on the main shaft. The inking platen lifts up the envelope from the continuously
moving feed band together with the stencil card underneath said envelope and
presses them against the stationary platen 10°.
40 and 40 are like spring fingers operating through recesses in the table 28° to
prevent the backward motion of the stencil card, with the slide 27b, when said
slide is moved toward the left to permit of the dropping of another card from the
magazine.
42 and 43 are rapidly running tapes operated from the pulley on the shafts of
roller 3 by means of the crossed belt 45°. These tapes are arranged in two sets at
a distance apart a little less than the length of an envelope, but greater than the
length of a stencil card.
46 is the magazine or collecting box for the stencil cards, and 47b is a similar
box for the printed envelopes.
The operation of this form of my invention is as follows:
Motion being given to the main shaft 8 in any convenient and proper way the
feed band 2 and 2* is given a continuous motion. The reciprocating slide 27 is
given a slow, equable motion to the right and slips off the bottoni card in the
magazine 30 of stencil cards. The said card is prevented from returning on the
quick return motion of the slide 27 by reason of the retarding effect of the spring
fingers 40 and 40. The second movement of the slide forces out another card,
and drives the first card to the extreme position toward the right shown in Fig. 1B..
A third motion of the slide 27 forces the first card out into the position at the
extreme right shown in Fig. 2B, and upon the rapid return of said slide to seize a
fourth card from the magazine the first card is dropped upon the feed band 2°
and 2. Fig. 3 shows the slide upon its return motion just before the card at the
extreme right is dropped. The motion of the slide is so quick that the card falls
flat upon the feed band, and this action is assisted and regulated by reason of the.
fact that the envelope in the grasp of the suction fingers 35b, comes down on top of
the stencil card at the exact moment the support of the slide 27" is withdrawn
from under it, and the two are deposited on the feed band as shown in Fig. 1.
The motion of the feed band, carries each stencil card with its envelope on top of
it along to the inking mechanism and the different parts of the machine are so timed
that at the moment each envelope and card arrives under the stationary platen 10°
the inking platen 11 comes up, lifts the card and envelope from the feed band,
forces them against the platen 10%, prints the address on the card upon the
envelope, and then in its downward motion the inking platen leaves the card and
printed envelope upon the feed band to be carried forward by the latters motion.
When these arrive over the roller 3b, the rapidly moving tapes 42 and 43 pick up
the envelope and shoot it over into the collection box 47b.

page_text: The shorter stencil card is not touched by these tapes but passes between them
and falls between the two sets of tapes into the collection box 46. When the
magazines and collection boxes are respectively emptied or filled, they can be
removed and replaced by new ones.
The slide 27 is extended out underneath the projecting portion of the table 28°
to form a set of guides through which the cards are moved after they have been
slipped off the bottom of the column of such cards standing in the magazine 30º.
The guides so formed extend toward the inking mechanism and serve to deliver
the card to that portion of the machine. In the construction illustrated the guides
do not deliver the cards immediately to the inking mechanism but are assisted by
other co-operating mechanism above described.
In other forms of mechanism which might be readily designed by those skilled
in the art, but still involving the principles of my invention, as here disclosed, the
guides may deliver the cards immediately to the inking mechanism, but it is
evidently a question of degree to what extent these guides bridge over the gap
between the magazine of cards and the inking mechanism, and whether said guides
deliver the cards immediately or mediately through the assistance of further
mechanisin to the inking apparatus, the principle of operation is still within the
scope of my invention."
It is also evident that the under guide, instead of being a portion of the
moving slide, might be stationary, while the slide would operate through a slot
or open space in said under guide. The principle of operation would be the
-same, though the details of construction would be slightly modified.
My invention further consists of a peculiar form of non-metallic stencil card to
be used in any of the types of addressing machine covered by my invention. These
stencil cards should be of non-metallic material such as oil paper parchment etc.
in order that the address may be perforated or otherwise stencilled
upon them
rapidly and cheaply, and furthermore that their first cost may be kept down to the
lowest figure, so that they may be discarded when the addresses are changed
without costing too much for renewals. In the use of such a set of cards certain
difficulties arise. During the operation of printing, one side of each card is rubbed
by an inking platen or roller, and, of course, has more or less of that side
permanently inked or smudged. At the same time the other face of the card,
which is to bear against the blank to be printed must be kept clean. When
ordinary cards are stacked together in a magazine, each card having one of its
faces inked as above described, it is evident that that side will bear against the
clean face of the next card and all cards will be inked upon both sides and their
further usefulness destroyed. To avoid this difficulty I propose to use cards
with their edges re-enforced or thickened to a degree in excess of the thickness
of the main portion of the card, so that the back of each card through which the
ink adheres will be held up away from the face of the next card in the pack
when they are stored in the inagazine, and thus the face of each will accordingly
remain clean.
The making of a non-metallic card which shall present these features is
difficult in that if the thickening or re-enforcing is made in the usual way by
pasting or otherwise permanently attaching a strip of some foreign material to
all the edges of the card, the main body of the card and the foreign material
around its edges will not expand and contract under the varying condition of
heat and moisture at the same rate, and the card will be badly warped and twisted
by the unequal expansion and contraction of the parts, and its usefulness thereby
destroyed. To secure the results above specified and to avoid the difficulties
described I have invented a form of non-metallic stencil card illustrated in Fig. 6
of the drawings.
Referring to Fig. 6, A is the main portion of the stencil card in which the
address is perforated. B is a re-enforced edge or frame which is thicker than the
portion A. This re-euforcing portion B may be made of paste-board or other
suitable stiff material and should be attached to the portion A of the card along

page_text: one of its edges only, as along one of the short edges Y or along the longer edge X
or along a short portion of both. The re-enforcing frame B might also be made
double, and the two parts be pasted together at the edges while the portion A of
the card is held between them by simple friction.
Again, the stiffening and re-enforcing effect might be produced by embossing
the border portion up from the main body of the main body A of the card itself
and bending over a part of the embossed portion.
It is evident that any one of these types of the general form of card invented
by me will perform the functions required in my machine and avoid the difficulties
above referred to.
Improvements in Means or Apparatus for Use in Addressing
Envelopes, Post Cards, Wrappers, and the like.
I, FRANK DRAYTON BELKNAP, of 314-316 Broadway, New York City,
United States of America, Publisher of Trade Lists, 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 :-
My invention relates to what are known as addressing machines. That is
machines by which a number of envelopes, postal cards, newspaper wrappers, or
other articles can be printed each with one name from a long list of such names
and addresses, and mailed accordingly. It is specifically designed to apply to that
class of addressing machines in which non-metallic stencils are used. These stencils
have heretofore commonly been used in the shape of long rolls of parchment or
similar suitable material upon which have been written the names and addresses by
means of perforations through said parchment. As frequent corrections, additions
and erasures are necessary in any such list, it has been a matter of great difficulty
to make these changes on such a roll and still preserve the alphabetical order or
other classification of the names. To overcome this difficulty, I propose to
substitute for the parchment roll a set of small non-metallic perforated stencil
cards which can be packed in a magazine like cards of a card catalogue, and easily
removed or added to.
:
My present invention consists of a simple machine specifically designed to use
such card stencils in the addressing of envelopes, etc. together with a specific form of
non-metallic stencil card to be employed therewith. The machine and card are
illustrated in the seven sheets of drawings filed with my Provisional Specification,
in which
Fig. 1, is a side view of the machine.
Fig. 2, is a longitudinal section.
Fig. 3, is a plan view with the envelope magazine removed.

Fig. 7, is another longitudinal section of the machine showing a modified form of
the printing mechanism.
Fig. 18, is a longitudinal section of a third form of machine embodying my
invention.

page_text: Fig. 2B, is a section of a detail of this form of card feeding mechanism, showing
the slide in its fartherest position to the right.
Fig. 3B, is a similar view showing the slide partially retracted.
Fig. 4B, is a plan view of the card magazine, table supporting the same and slide
mechanism.
Fig. 5B, is a half rear elevation and half cross section of the slide mechanism.
Throughout the drawings, like reference figures refer to like parts.
1, represents the main frame of the machine.
2, is an endless feed band which passes through the printing mechanism, carries
to it the envelopes and card stencil in position for printing, and afterwards
delivers them to suitable receptacles. This feed band runs around pulleys 3, 4
and 5, and over the driving drum 6. On the band at uniform distances are sets of
hooks, 7, which serve to hold the cards on to the band, during a portion of its
travel and also to properly space them. This endless feed band may be solid, and
the printing done over its edges or it may have openings cut in it through which
the printing could be done, but preferably I make it double, composed of the two
parts, 2 and 2 A, as best shown in Figure 3. The two parts then suffice to carry
the cards and articles to be printed while the printing and some of the other feed
mechanism can operate between the two portions of the double band.
8, is a magazine of stencil cards, having its cover thrown back, and when in use
placed upon the bracket 9.
10, is a magazine of envelopes, postal cards or other articles to be printed,
resting on bracket 11. The stencil cards and articles to be printed can be fed out
slowly toward the mouths of their magazines, by means of a spiral spring or other
mechanism, not shown.
8, is a magazine for stencil cards being charged or used as a collection box.
This together with 10°, a similar collection box for the envelopes or printed articles,
stand on the bracket 12, at the delivery end of the machine. The box for the
smaller of the two sets of articles (that is the stencil cards and the envelopes) is
placed next to the machine with its mouth just at the turning point of the endless
feed band 2. At this point the band goes around roller 3 and changes from a
horizontal to a downward direction of motion. The result is, that the printed
envelope and stencil card are shot down over the mouth 13 of the collection box 8",
which mouth is inclined as shown. The stencil card falls into its collection box
while the larger envelope slides over its mouth and drops into that of its particular
collection box 10, the mouth of which 14, is inclined in an opppsite direction to
prevent the envelope shooting beyond.
It is evident that an intermittent motion should be given to the endless feed
band equal in motion to the distance between any two adjacent sets of hooks 7.
This is accomplished by means of the ratchet wheel 15, and pawl 16, which
together form a pawl and ratchet motion. The pawl is mounted on the link 17,
and is given a reciprocating motion by the link 18, which is connected to the
rotating gear wheel 19, which is on the main driving shaft 21. The ratchet
wheel 15, is of course keyed to the shaft of the driving drum 6.
The main shaft 21, is driven by the belt pulley 22. Keyed to the main shaft is
. the eccentric 23, which by means of the eccentric rod 24, gives a reciprocating
motion to the bell crank 25. This bell-crank operates, through the link 26, the
suction arms 27, which are fitted up with the rubber suction pieces 28. I have
shown two of these arms which are mounted on a tubular shaft 43. These arms
move between the two parts of the double feed band as shown in Fig. 3.
29, is another branch of the bell-crank 25, which by means of the link, 30,
operates a similar set of suction arms 31, provided with rubber suction mouths 32,
and mounted on hollow shaft 43 A. These two suction arms operate outside of
the feed band 2, as shown in Fig. 3 and do not interfere with the stencil card which
is lying upon it at that point.
The bell-crank 25, by means of the piston rod 33, and piston 34, also operates
the air pump 35, which is pivoted to the main frame at 36.

page_text: 37, is a flexible pipe which by means of the branch pipes 38 and 39, 15 connected
with the hollow tubular shafts 43 and 43 A, respectively. The connection between
the tubular shafts 43 and 43 A, and the pipes 38 and 39, is rendered air-tight by
means of the stuffing boxes 40 and 40 A, as best shown in Figs. 1 and 3.
It is evident without further describing the operation of the machine at this
point that the suction mouths 28, pick up the topmost stencil card 41, and lay it on
the feed band 2, before one of the sets of hooks 7, while the suction mouths 32,
will pick up the first envelope in the magazine 10, and deposit it on said feed band
before another set of hooks, and on top of the stencil card already deposited there
by previous operations of the machine.
It now remains to describe the printing mechanism.
44, is a cam on the main shaft which is full faced through 180 degrees and
partially cut away through the other 180 degrees. This operates the cam roller 45,
which is on the slide connected to the link 46. There are two sets of these cams,
slides and links, one on either side of the machine, and the links are pivoted to the
cross bar 47 A, of the vibrating platen 47. This platen 47, I have shown pivoted to
the main frame and vibrated by the mechanism last described, together with the
springs 48, which hold the rollers 45, against the cams 44, and lift the platen 47
during one half of the revolution of the main shaft.
The gear 20, keyed on the shaft 20 A, meshes with the gear 19, on the main shaft
and is driven thereby. The shaft 20 has the cam 50, which by means of the cam
roller 49 A, gives the ink platen 49, a vertical reciprocating motion.
51 is the roller of an ordinary ink fount and 52, is a small inking roller which
normally rests on the shelf 53, which is close beside the platen 49, when in its
lower-most position, and on the opposite side of it from the ink fount. This inking
roller is mounted on the flexible arm 54, pivoted to the lever 55, which is mounted
on the strut 56, bolted to the main frame, as shown in Fig. 2. The lever 55 has a
cam roller 57, on its lower end which runs on the very quick cam 58 also mounted
on the shaft. 20 A. The spiral spring 59 serves to keep the lever 55, in such position
that its cam roller 57 is against the cain 58, and the inking roller 52, is normally
held over the shelf, 53. The spring 60, serves to force the link 54 downward, so
that said inking roller 52, will not fly up from the shelf 53. The spring 61, pulls
down the reciprocating platen 49, when it is not positively lifted by the action
of the cam 50.
In the modification illustrated in Fig. 7, another inking apparatus is shown, in
which the large bell crank 74, is vibrated by the eccentric cam 75. This bell
crank 74, carries a number of inking rollers 77, which run from a curved inking
surface 76, which extends over to the ordinary form of ink fount shown in the
other drawings as well. These inking rollers 77, are mounted in longitudinally
sliding links 78, whose inner euds are provided with cam rollers 79, and springs 81.
These cam rollers run over a stationary cam piece 80, which has a central
horizontal portion and an inclined portion on either side.
74 A is a loose inking roller which transmits the ink from the fount to the
surface 76.
The operation of this form of my improved machine is as follows:-
Motion being given to the main shaft 21, by the belt pulley 22, the gear 19 is
rotated and the ratchet gear 16, vibrated so that the driving drum 6, is given a
quarter of a revolution during one half of the revolution of the main shaft, and
allowed to stand at rest the other half. This gives the feed band 2 an inter-
mittent forward motion, which motion being equal to a quarter of the circumference
of the driving drum 6, or the distance between two adjacent sets of hooks 7.
This revolution of the main shaft, by means of the eccentric 23, and connections
causes the suction arms 27 to be pressed down against the topmost stencil card
in the magazine 8, and at the moment such suction arms start on their backward
motion the piston 34, begins to move out of the air pump 35, and the suction thus
created extending through the pipes 37 and 38, causes the stencil card to adhere to
the suction mouths 28, and the continued upward motion of the arms 27, brings
bs

page_text: the said stencil card against the feed band, 2, and holds it there for a second
until the said feed band begins to move by the proper timing of the mechanism
and one of the sets of hooks lifts the card 41, away from the suction arms which
had held it up to that moment.
The second revolution of the driving shaft has lifted the stencil card 41, up to
the horizontal portion of the feed band 2, and during such second revolution the
vibrations of the suction arins 31 have, through the agency of the suction mouths 32,
and pipe 39 and pump 35 as before described, brought down an envelope from the
magazine 10 and placed it over the stencil card, as shown in Fig. 2. Just before
the suction mouths 32 let go of the said envelope, the envelope is wrenched away
from it by the motion of the feed band, and hooks, as before described, and
the envelope lying over the stencil card is carried along toward the printing
mechanism.
In the arrangements of parts shown in these figures of the drawings two of
the intermittent motions of the feed band will carry the envelope and card we
are following under the supporting platen 47. The next rotation of the main
shaft will bring the full portion of the cam 44 against the cam roller 45 and drop
down the supporting platen, 47 upon the envelope. The same motion of the shaft
will, when this has been accomplished, have turned the gear wheel 20, and the
cam 50, far enough to drive up the reciprocating inking platen 49. This will
press against the stencil card and envelope which are backed by the supporting
platen, 47, and a portion of the ink being forced through the perforations of the
stencil card the name and address so perforated will be printed on the envelope.
A complete revolution will have lifted the supporting platen 47, and with-
drawn the inking platen 49. The next motion of the feed band will carry the
card and addressed envelope forward and discharge them. From the edge of
the machine they will drop into their respective collection boxes, as before
described. When these boxes are full they can be removed and empty ones
substituted.
The collection box of stencil cards when filled becomes a magazine to be placed
when needed upon bracket 9 and used to feed the machine again.
While the inking platen 49, is at rest, in its lowermost position, as it is about
during one half of the revolution of the cam 50, the quick motion of cam 58,
vibrates the lever 55, and drives the inking roller 52, over and on to the roller 51
of the ink fount, and when the same is withdrawn on the passage of cam 58, it rolls
across the platen 49 and freshly inks it.
The construction of the modification illustrated in Fig. 7 is in every way similar
excepting that the ink in the fount is spread over the curved surface 76, by the
loose roller 77 and from this surface 76 is picked up by the rollers 77, which are held
down to it by the springs 81 during a major portion of each oscillation of the bell
crank 74. As the rollers 77 come under the stencil card which is held down by the
envelope, and supporting platen back of it, said rollers 77, are raised by reason of
the cam rollers 79, running over the raised portion of the cam 80, and said rollers
are run across the under face of the stencil card, and the ink is forced through its
perforations on to the envelope, as before.
Various changes could be made in the construction of this form of my machine,
without departing from the spirit of my invention.
The printing mechanism might be placed above the feed band, and the stencil
placed on top of the envelope which would simply necessitate a reversal of the
positions, of the stencil and envelope, magazines and collection boxes.
The arrange-
ment of hollow shafts and suction arms could be replaced by a solid construction
with flexible rubber tube extending from the air pump to the suction mouths on the
ends of the arms. The eccentrics might be replaced by cranks, and cranks in turn
by cams if necessary at various points, as is well understood by those skilled in
mechanism.
Referring now to the third form of my invention, illustrated in Figures 1B to
Fig. 5B, inclusive.

page_text: 1b is the main frame of the machine. 2b is an endless feed band which preferably
is composed of two parts, 2 and 2* as described in the first part of this Specification,
and a large portion of the machine not herein specifically described conforms to the
construction fully shown and described in said first part of this Specification. The
feed band runs around the pulleys 3b, 4 and 5. The pulley 5b is driven by
the larger pulley 6' which is keyed on to its shaft. The pulley 6b is driven by the
belt 7 which runs around a smaller pulley on the main shaft 8b.
34 is a series of envelopes, postal cards or other articles which are to be
addressed, placed in a magazine 34°.
32 is a similar series of stencil cards contained in a magazine 30° which rests
upon the table 28, and is prevented from moving horizontally by reason of the
strap 31 encircling the vertical portion of the angle iron 29, which angle iron is
bolted to the said table 28. Running beneath said table 28 and beneath the mouth
of the magazine 30°, is the reciprocating slide 27b which is mounted in grooved
portions 41 of the inain frame of the machine as best shown in Fig. 5B.
This slide 27 has a raised portion 33 which is equal to or slightly less than the
thickness of one of the stencil cards 32b.
The slide 27 should be given a reciprocating motion, and preferably that motion
should be of only moderate rapidity toward the right, but there should be a quick
return motion toward the left. The preferred mechanism for producing this
motion, consists of the cam 19b on the shaft 19* which by means of the reciprocating
link, 21, the cam roller 20 mounted thereon, the retracting spring 22, the lever 23°
pivoted to the main frame at 24%, and link 25b and lugs 26 transmits a slow outward
motion and a quick return motion to the slide 27, as will be readily understood by
referring to Fig. 1B of the drawing. The shaft 19" is revolved by means of a
pinion 18 meshing with the pinion 17 on the main shaft 8b.
The envelopes 34° are fed down one at a time on the endless feed band by means
of the suction fingers 35%, operated by the link 36b, bell-crank 37b, eccentric rod 38°,
and eccentric 39b on the shaft 19, as fully described in the first part of this
Specification.
The inking mechanism consists of the reciprocating inking platen 11°, operated
by the cam 9b on the main shaft and the retracting spring 16, acting with the ink-
fount 12, inking roller 13b, and connecting level 14 operated by the cam 15, on
the main shaft. The inking platen lifts up the envelope from the continuously
moving feed band together with the stencil card underneath said envelope and
presses them against the stationary platen 10°.
40 and 40 are like spring fingers operating through recesses in the table 28' to
prevent the backward motion of the stencil card, with the slide 27, when said slide
is moved toward the left to permit of the dropping of another card from the
magazine.
42 and 43 are rapidly running tapes operated from the pulley on the shafts of
roller 3 by means of the crossed belt 45%. These tapes are arranged in two sets at
a distance apart a little less than the length of an envelope, but greater than the
length of a stencil card.
46 is the magazine or collecting box for the stencil cards, and 47 is a similar
box for the printed envelopes.
The operation of this form of my invention is as follows:--
Motion being given to the main shaft 8 in any convenient and proper way the
feed band 2 and 2 is given a continuous motion. The reciprocating slide 27" is
given a slow, equable motion to the right and slips off the botton card in the
magazine 30 of stencil cards. The said card is prevented from returning on the
quick return motion of the slide 27 by reason of the retarding effect of the spring.
fingers 40 and 10%. The secoud movement of the slide forces out another card, and
drives the first card to the extreme position toward the right shown in Fig. 18.
A third motion of the slide 27b forces the first card out into the position at the
extreme right shown in Fig. 2B, and upon the rapid return of said slide to seize a
fourth card from the magazine the first card is dropped upon the feed band 2° and 2".

page_text: Fig. 3 shows the slide upon its return motion just before the card at the extreme
right is dropped. The motion of the slide is so quick that the card falls flat upon
the feed band, and this action is assisted and regulated by reason of the fact that
the envelope in the grasp of the suction fingers 35°, comes down on top of the
stencil card at the exact moment the support of the slide 27" is withdrawn from
under it, and the two are deposited on the feed band as shown in Fig. 1. The
motion of the feed band, carries each stencil card with its envelope on top of it
along to the inking mechanism and the different parts of the machine are so timed
that at the moment each envelope and card arrives under the stationary platen 10"
the inking platen 11 comes up, lifts the card and envelope from the feed band,
forces them against the platen 10b, prints the address on the card upon the
envelope, and then in its downward motion the inking platen leaves the card and
printed envelope upon the feed band to be carried forward by the latter's motion.
When these arrive over the roller 3b, the rapidly moving tapes 42 and 43b pick up
the envelope and shoot it over into the collection box 47b. The shortest stencil
card is not touched by these tapes but passes between them and falls between the
two sets of tapes into the collection box 46°. When the magazines and collection
boxes are respectively emptied or filled, they can be removed and replaced by new
ones.
. The slide 27 is extended out underneath the projecting portion of the table 28b
to form a set of guides through which the cards are moved after they have
been slipped off the bottom of the column of such cards standing in the magazine 30º.
The guides so formed extend toward the inking mechanism and serve to deliver
the card to that portion of the machine. In the construction illustrated the guides
do not deliver the cards immediately to the inking mechanism but are assisted by
other co-operating mechanism above described.
In other forms of mechanism which might be readily designed by those skilled in
the art, but still involving the principles of my invention, as here disclosed, the
guides may deliver the cards immediately to the inking mechanism, but it is
evidently a question of degree to what extent these guides bridge over the gap
between the magazine of cards and the inking mechanism, and whether said guides
deliver the cards immediately or mediately through the assistance of further
mechanism to the inking apparatus, the principle of operation is still within the
scope of my invention.
It is also evident that the uuder guide, instead of being a portion of the moving
slide, might be stationary, while the slide would operate through a slot or open
space in said under guide. The principle of operation would be the same, though
the details of construction would be slightly modified.
My invention further consists of a peculiar form of non-metallic stencil card to
be used in any of the types of addressing machine covered by my invention. These
stencil cards should be of non-metallic material such as oil paper parchment etc. in
order that the address may be perforated or otherwise stencilled upon them rapidly
and cheaply, and furthermore that their first cost may be kept down to the lowest
figure, so that they may be discarded when the addresses are changed without
costing too much for renewals. In the use of such a set of cards certain difficulties
arise. During the operation of printing, one side of each card is rubbed by an
inking platen or roller, and, of course, has more or less of that side permanently
inked or smudged. At the same time the other face of the card, which is to bear
against the blank to be printed must be kept clean. When ordinary cards are
stacked together in a magazine, each card having one of its faces inked as above
described, it is evident that that side will bear against the clean face of the next
card and all cards will be inked upon both sides and their further usefulness
destroyed. To avoid this difficulty I propose to use cards with their edges
re-enforced or thickened to a degree in excess of the thickness of the main portion
of the card, so that the back of each card through which the ink adheres will be
held up away from the face of the next card in the pack when they are stored in
the magazine, and thus the face of each will accordingly remain clean.

page_text: The making of a non-metallic card which shall present these features is difficult
in that if the thickening or re-enforcing is made in the usual way by pasting or
ctherwise permanently attaching a strip of some foreign material to all the edges of
the card, the main body of the card and the foreign material around its edges will
not expand and contract under the varying condition of heat and moisture at the
same rate, and the card will be badly warped and twisted by the unequal expansion
and contraction of the parts, and its usefulness thereby destroyed. To secure the
results above specified and to avoid the difficulties described I have invented
a form of non-metallic stencil card illustrated in Fig. 6 of the drawings.
Referring to Fig. 6, A is the main portion of the stencil card in which the
address is perforated. B is a re-enforced edge or frame which is thicker than the
portion A. This re-enforcing portion B may be made of paste-board or other
suitable stiff material and should be attached to the portion A of the card along.
one of its edges only, as along one of the short edges or along the longer edge X
or along a short portion of both. The re-enforcing frame B might also be made
double, and the two parts be pasted together at the edges while the portion A of
the card is held between them by simple friction. Again, the stiffening and
re-enforcing effect might be produced by embossing the border portion
the main body of the main body A of the card itself and bending over a part of the
embossed portion.

It is evident that any one of these types of the general form of card invented by
me will perform the functions required in my machine and avoid the difficulties
above referred to.
