Improvements in Stencil Printing Machinery.
I, FRANK DRAYTON BELKNAP, President of the Rapid Addressing Machine
Company, of 314, Broadway, New York City, United States of America, do hereby
declare the nature of this invention to be as follows:-
My invention relates to the art of printing and consists of a mechanism for
printing by means of stencil cards or other stencils. Various kinds of mechanism
for this purpose have been heretofore patented to me but it has become desirable
to simplify and reduce the amount of mechanism involved in each machine, and
to do away with intermittent motion of the special printing mechanism in
order to increase the speed. To secure these and other advantages I have designed
a simple and rapidly working mechanism, the preferred form of which is illustrated
in the accompanying four sheets of drawings, in which:-
Figure 1, is a side view or elevation of the machine.
Figure 2, is a longitudinal section thereof, on line 2-2 of Figure 3.
Figure 3, is an end elevation of the machine, looking from the right hand
end of Figure 1, and with the collection boxes removed.
Figure 4, is an enlarged detail in section of the stencil card magazine and
feeding dog.
Figure 5, is a face view of my preferred form of stencil card, and
Figure 6, is a section of a portion thereof taken on line 6-6 of Figure 5.
Figure 7, is an enlarged detail view in section of the printing mechanism,
the magazine of objects to be printed, and the automatic feed for said objects.
Figure 8, is an enlarged detail of the gearing for said feed mechanism.
Figure 9, is a detail showing the method of attachment of the inking pad
to its shaft.
Figure 10, is a detail view showing the ejector mechanism.
Figure 11, is a vertical section of the machine with a modification of the parts,
designed to print wrappers, or other articles when fed by hand.
Figure 12, is a detail plan view of the gearing and clutch for same.
Throughout the drawings like reference figures refer to like parts.
1, represents the main frame of the machine. 2, is the main shaft journaled
in said frame, and driven by belt pulley 3. 4, is a sprocket wheel mounted on
said shaft, and 5, a sprocket chain which transmits motion therefrom to the
sprocket wheel 6, on the shaft 7. On the other end of the shaft 7, as shown
in Figure 3, is the gear wheel 8, which meshes with the gear wheel 9, of equal
size on the shaft 10. 10, has a pinion 11, meshing with a gear 12 of twice the
diameter which in turn is mounted on the shaft 13. On this shaft 13, is the cut
away roller 14, having two portions of its face left full at opposite ends of the
same diameter as shown in Figure 2. 15, is a cut away roller or inking pad mounted
on the shaft 10, and having a radius just one-half the radius of the roller 14. The full
portions of these two rollers meet as they revolve, and as they are geared at
the rate of two to one they will have the same circumferential velocity. The inking
DQ27

page_text: pad 13, is attached to the shaft 10, by screws 16, (best shown in Figure 9) and
is also retained thereon by 'the rings 35, which compose the cam way for the
ejector mechanism.
:
17, is an ink roller rotating in, the ordinary form of ink fount 18, which has the
doctor block 19, adjustable by means of the set screw 20, all in the usual way,
This ink roller 17, is mounted on the shaft 7.
21, represents a series of stencil cards in a vertical magazine composed of the
strips 22-22. The reciprocating dog 23, forms the bottom of said magazine,
and has the projection 24 on its upper face. This dog is driven by link 25,
crank 26, on 'shaft 26, operated by crank 27 driven by eccentric rod 28, from
eccentric 29, on the main driving shaft 2. 30, represents one of the pair of parallel
horizontal guides having grooves on their inner. faces. and extending from the
bottom of magazine 22, to the point of tangency of the rollers 14 and 15.
The upper portion of said groove is cut away under the magazine so that the
bottom cards will fall from said magazine into line with the groove.
31, represents a long rod or extension fastened to the dog 23, and having the
upwardly projecting fingers 32, and 33, near its outer end. This rod rests in
the cam way 35 on the shaft 10, which cam way has a short raised portion 34, (see
Figure 10).
36, represents a collection box for the stencil cards which have been forced out
of the printing mechanism by the ejector finger 33, and 37, represents a similar
collection box for the printed objects, such as envelopes, which have been forced
out of the printing mechanism by the ejector finger 32. 38, is a guide for said
printed objects.
39, is a series of objects to be printed, such as envelopes, resting in the magazine
formed by the uprights 40-40. 41, is a metal strip forming a portion of the
bottom of said magazine, and extending around to the left in a semi-circle which
is tangential to said bottom."
So
.
42, 42 etc., are a series of similar guides of slightly larger radius than 41,
that a space is left between through which an envelope may pass.
43, is a semi-circular pusher mounted on the shafts 47, which rotates on an axis
coinciding with the center of the semi-circle outlined by the guides 41, and 42,
43, is also are shaped, and slips down between said semi-circular guides. The
shaft 47, is given periodic vibrations by means of the cut away gear 44, on
shaft 10, which has a portion of its teeth 45, left to engage with the pinion 46,
on the shaft 47. 48 is a spiral spring, which normally holds the shaft 47 in
position shown in Figure 2, with the stop 48", resting against the shaft 13. On
the teeth 44, engaging with the, teeth on pinion 46, a result secured without
jamming by means of the co-acting lugs 49 and 50 (see Figure 8), the shaft 47, is
given a partial rotation in a direction indicated by Figure 7, and when the
teeth 45, have passed the spring 48, returns the shaft to its normal position.....
51, 51, represent horizontal rods attached to the main frame 1, on which the
collection boxes 36 and 37, may be slid and adjustably fixed.
52, represents an improved form of stencil card composed of the paste-board
frame 53, to which the piece of stencil paper 52, is attached at four separate, points
as indicated at 54, (Figures 5 and 6).
In the modification illustrated in Figures 11 and 12, the shaft 13, is mounted
in the swinging frame 60-61, which is alternately raised and lowered by means
of the arm 62, engaging with the cam 63, of the, sleeve 2ª on the shaft 2.
64, is a spring which serves to keep the arm 62 always in engagement with the
cam 63, and 65 is a clutch operated by the lever 66, by which the driving
gear. 56-57 may be alternately thrown into engagement with the motor power
or be disengaged therefrom, to be operated by the handle 67. The motion is
transmitted from the gear 67 to the shaft 13 by means of the sprocket; chain .58,
running over the sprocket wheel 59.. When this modification is used the envelope
feed 40 is removed..
; 1.

page_text: .The operation of my invention is as follows:-When separate objects, such as
envelopes are stacked up in the magazine 40, with the flaps of the envelope
downward, and leaving the open flap on the left hand side, looking at Figure 2,
the stencil cards on which the addresses or other words have been pricked out are
stacked up in the magazine 22. The ink fount 18, is filled with ink and motion
given to the machine by means of the belt pulley 3. The dog 23, will begin
to reciprocate and catching the inner side of the frame 53, of the lower stencil
card (said cards being arranged in the magazine with the frame side down, as
represented in Figure 6), will force cards out along the parallel guides 30, one
behind the other in a continuous series. When the first card has arrived at
the point of tangency of the rollers 14 and 15, an envelope will have been fed
down on top of it by reason of the fact that the ends of the arc shaped
pusher 43, will have caught under the flap of the lowermost envelope at each
reciprocation, and forced, the same down through the semi-circular guides 41
and 43, as indicated in Figure. 7. .It is a fact that the extreme ends of the flap
of an envelope will always project slightly away from the body of the envelope
because the paste on the major portion of said flap causes it to curl under, and
thereby lifts the extreme end, which has no paste, up from the face the distance
sufficient to permit a thin pusher like 43, to enter and secure a firm grip on the
envelope.
The stencil card and the envelope superimposed thereon being at the point of
tangency of the two rollers 14 and 15, are seized by the full faced portions thereof,
when they come around and carried forward a distance equal to the width of said
faces in the direction of the circumference of the roller. During this operation
the ink carried on the roller 15, is forced through the perforations of the stencil
card and the words or letters perforated therein are printed on the envelope.
When the full faced portions of the rollers let go of the card and envelope, the
dog 23, and extension 31, come forward to perform the double function of
feeding up another stencil card and ejecting the card and envelope already
printed. This last operation results by reason of the fact that the full faced
portion 34, of the cam way 35, comes under the rod 31, and lifts it so that the
fingers 32 and 33, strike the envelope and stencil card respectively and snap
them "out. On the backward stroke of the rod 31, the cam face 34 is out of
engagement, so that the fingers 32 and 33 travel back below the level of the new
card and envelope placed in position for printing by the next operation.
The ejected card falls into the collection box 36, the envelope, being larger, than
the dimensions of said collection box, passes over its mouth and slides down the
guides 38, into the collection box 37.
The shaft 47, is shown bent to one side throughout its central portion. This is
to enable it to clear the roller 14, and is a feature of construction rendered
necessary by the proportion of the part in this particular machine, and constitutes
no feature of the invention.
The teeth 45, on the cut away gear 40, sometimes jam against the teeth on the
pinion 46, and lugs 49 and 50 are riveted to the sides of said gear wheel and pinion
to cause the teeth fo register and intermesh.
When a small job is to be run off or when the long envelopes or wrappers or
other unhandy objects are to be printed, the modification shown in Figures 11
and 12, is preferably employed, and the articles to be addressed are then fed in
by hand. The object in giving the upper roller a rising and falling motion is
to enable the operator to feed the article in with ease and without danger of
having his fingers caught in the machine.
Numerous changes could be made in the details of my invention without
departing from the principle thereof. The number of full faced portions of
the rollers 14 and 15 might be varied if their relative speeds of rotation were
varied accordingly. Other forms of stencil feeding card mechanism and different
forms of stencil cards might be used. The ejector mechanism might be varied,

page_text: or in some cases dispensed with, and so on without detracting from the advantages
of my improved apparatus which consists in its compactness and smoothness and
rapidity of action, combined with small first cost.
It is evident that in order to prevent the smearing of ink on the roller 14 and
its consequent transfer to the backs of the objects to be printed, the dimension
of the ink carrying pad or roller 15, in the line of its motion should be only equal
to and preferably less than the width of the stencil card. In the particular
construction which I have here illustrated it is also necessary that the other
dimension of the ink carrying pad, in the line of its axis, should be less than the
distance between the parallel guides in order that it may pass between them, and
grip the stencil card, consequently the dimensions of the ink carrying pad both
ways should be less than the dimensions of the stencil card.
Dated this 24th day of August 1897.

Throughout the drawings like reference figures refer to like parts.

page_text: 1, represents the main frame of the machine. 2 is the main shaft journalled
in said frame, and driven by belt pulley 3. 4 is a sprocket wheel mounted on
said shaft, and 5, a sprocket chain which transmits motion therefrom to the
sprocket wheel 6, on the shaft 7. On the other end of the shaft 7, as shown
in Figure 3, is the gear wheel 8, which meshes with the gear wheel 9, of equal
size on the shaft 10. 10, has a pinion 11, meshing with a gear 12 of twice the
diameter which in turn is mounted on the shaft 13. On this shaft 13, is the cut
away roller 14, having two portions of its face left full at opposite ends of the
same diameter as shown in Figure 2. 15, is a cut away roller or inking pad mounted
on the shaft 10, and having a radius just one-half the radius of the roller 14. The full
portions of these two rollers meet as they revolve, and as they are geared at
the rate of two to one they will have the same circumferential velocity. The inking
pad 13, is attached to the shaft 10, by screws 16, (best shown in Figure 9) and
is also retained thereon by the rings 35, which compose the cam way for the
ejector mechanism.
17 is an ink roller rotating in the ordinary form of ink fount 18, which has the
doctor block 19, adjustable by means of the set screw 20, all in the usual way.
This ink roller 17, is mounted on the shaft 7.
21 represents a series of stencil cards in a vertical magazine composed of the
strips 22-22. The reciprocating dog 23, forms the bottom of said magazine,
and has the projection 24 on its upper face. This dog is driven by link 25,
crank 26, on shaft 26, operated by crank 27 driven by eccentric rod 28, from
eccentric 29, on the main driving shaft 2. 30 represents one of the pair of parallel
horizontal guides having grooves on their inner faces and extending from the
bottom of magazine 22, to the point of tangency of the rollers 14 and 15.
The upper portion of said groove is cut away under the magazine so that the
bottom cards will fall from said magazine into line with the groove.
31 represents a long rod or extension fastened to the dog 23, and having the
upwardly projecting fingers 32, and 33, near its outer end. This rod rests in
the cam way 35 on the shaft 10, which cam way has a short raised portion 34, (see
Figure 10).
36 represents a collection box for the stencil cards which have been forced out
of the printing mechanism by the ejector finger 33, and 37, represents a similar

out of the printing mechanism by the ejector finger 32. 38 is a guide for said
printed objects.
39 is a series of objects to be printed, such as envelopes, resting in the magazine
formed by the uprights 40 40. 41 is a metal strip forming a portion of the
bottom of said magazine, and extending around to the left in a semi-circle which
is tangential to said bottom. 42, 42 etc. are a series of similar guides of slightly larger
radius than 41, so that a space is left between through which an envelope may pass.
43, is a semi-circular pusher mounted on the shafts 47, which rotates on an axis
coinciding with the centre of the semi-circle outlined by the guides 41 and 42.

shaft 10, which has a portion of its teeth 45, left to engage with the pinion 46,
on the shaft 47. 48 is a spiral spring, which normally holds the shaft 47 in
position shown in Figure 2, with the stop 48, resting against the shaft 13. On
the teeth 44, engaging with the teeth on pinion 46, a result secured without
jamming by means of the co-acting lugs 49 and 50 (see Figure 8), the shaft 47 is
given a partial rotation in a direction indicated by Figure 7, and when the
teeth 45, have passed the spring 48, returns the shaft to its normal position.
51, 51 represent horizontal rods attached to the main frame 1, on which the
collection boxes 36 and 37, may be slid and adjustably fixed.
52 represents an improved form of stencil card composed of the pasteboard

page_text: frame 53, to which the piece of stencil paper 52, is attached at four separate points
as indicated at 54, (Figures 5 and 6)."
In the modification illustrated in Figures 11 and 12, the shaft 13, is mounted
in the swinging frame 60-61, which is alternately raised and lowered by means
of the arm 62, engaging with the cam 63, of the sleeve 2 on the shaft. 2.
64 is, a spring which serves to keep the arm 62 always; in engagement with the
cam "63, and 65 is a clutch operated by the lever 66, by which the driving
gear 56-57 may be alternately thrown into engagement with the motor power
or be disengaged therefrom, to be operated by the handle 67. The motion, is
transmitted from the gear 67 to the shaft 13 by means of the sprocket, chain 58,
running over the sprocket wheel 59. When this modification is used the envelope
feed 40 is removed.
"
I
The operation of my invention is as follows:-When separate objects, such as
envelopes are stacked up in the magazine 40, with the flaps of the envelope
downward, and leaving the open flap on the left hand side, looking at. Figure 2,
the stencil cards on which the addresses or other words have been pricked out are
stacked up in the magazine 22. The ink fount 18, is filled with ink and motion
given to the machine by means of the belt pulley 3. The dog. 23, will begin
to reciprocate and catching the inner side of the frame 53, of the lower stencil
card (said cards being arranged in the magazine with the frame side down, as
represented in Figure 6), will force cards out along the parallel guides 30, one
behind the other in a continuous series. When the first card has arrived at
the point of tangency of the rollers 14 and 15, an envelope will have been fed
down on top of it by reason of the fact that the ends of the are shaped
pusher 43, will have caught under the flap of the lowermost envelope at each
reciprocation, and forced the same down through the semi-circular guides 41
and 43, as indicated in Figure 7. It is a fact that the extréme ends of the flap
of an envelope will always project slightly away from the body of the, envelope
because the paste on the major portion of said flap causes it to curl under, and
thereby lifts the extreme end, which has no paste, up from the face the distance
sufficient to permit a thin pusher like 43, to enter and secure a firm grip on the
envelope.
The stencil card and the envelope superimposed thercon being, at the point of
tangency of the two rollers 14 and 15, are seized by the full faced portions thereof,
when they come around and carried forward a distance equal to the width of said
faces in the direction of the circumference of the roller. During this operation
the ink carried on the roller 15, is forced through the perforations of the stencil
card and the words or letters perforated therein are printed on the envelope.
When the full faced portions of the rollers let go of the card and envelope, the
dog 23, and extension 31, come forward to perform the double function of
feeding up another stencil card and ejecting the card and envelope already
printed. This last operation results by reason of the fact that the full faced
portion 34, of the cam way 35, comes under the rod 31, and lifts it so that the
fingers 32 and 33, strike the envelope and stencil card respectively and snap
them out. On the backward stroke of the rod 31, the cam face 34 is out of
engagement, so that the fingers 32 and 33 travel back below the level of the new
card and envelope placed in position for printing by the next operation.
The ejected card falls into the collection box 36, the envelope being larger, than
the dimensions of said collection box, passes over its mouth and slides down the
guides 38, into the collection box 37.
The shaft 47 is shown bent to one side throughout its central portion. This is
to enable it to clear, the roller 14, and is a feature of construction rendered
necessary by the proportion of the part in this particular machine, and constitutes
no feature of the invention.
The teeth 45, on the cut away gear 40, sometimes jam against the teeth on the

page_text: pinion 46, and lugs 49 and 50 are riveted to the sides of said gear wheel and pinion
to cause the teeth to register and intermesh:
When a small job is to be run off or when the long envelopes or wrappers or
other unhandy objects are to be printed, the modification shown in Figures 11
and 12, is preferably employed, and the articles to be addressed are then fed in
by hand. The object in giving the upper roller a rising and falling motion is
to enable the operator to feed the article in with ease and without danger of
having his fingers caught-in-the-machine.
..
Numerous changes could be made in the details of my invention without
departing from the principle thereof. The number of full faced portions of
the rollers 14 and 15 might be varied if their relative. speeds. of rotation were
varied accordingly. Other forms of stencil feeding card mechanism and different
forms of stencil cards might be used. The ejector mechanism might be varied,
or in some cases dispensed with and so on without detracting from the advantages
of my improved, apparatus which consists in its compactness and smoothness and
rapidity of action, combined- with small first cost.
.
. It is evident that in order to prevent the smearing of ink on the roller 14' and
its consequent transfer to the backs of the objects to be printed, the dimension
of the ink carying pad or roller 15, in the line of its motion should be only equal
to and preferably less than the width of the stencil card. In the particular
construction which I have here illustrated it is also necessary that the other
dimension of the ink-carrying pad, in the line of its axis, should be less than the
distance between the parallel guides in order that it may pass between them, "and
grip the stencil card, consequently the dimensions of the ink carrying pad both
ways should be less than the dimensions of the stencil card.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
