Improvements in Bordering-machines for Letter-papers and
Letter-covers.
I, HEINRICH MUTH, of Coblenz, Rhenish Prussia, Germany, Merchant 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 improvements in bordering-machines in which letter-
paper and letter-covers are mechanically taken out of a vessel containing the
loose packet of papers, then laid upon a table mechanically moved from the head
of the machine to its foot, and, during this motion, are bordered by a rotating
brush; and the objects of my improvement are, first, to provide a bordering-
machine in which by means of gears and sprockets a wallover is turned continuously
that takes one by one the paper-sheets to be bordered out of the vessel wherein
the papers loose are contained; second, to provide a trundle-seizer by means of
which the said sheets are hold, and, when it turns, laid upon a table; third, to
provide a clutch-mechanism whereby the said table may be moved discontinuously
from the head to the foot of the machine, said clutch-mechanism being provided"
with gears and slot to move it to and fro and with an eccentric bar penetrating
with its sharp extremity between the two-parted clutch-mechanism to have it seize
periodically with a pin in a hole-disk the discontinuously turning of which operates
by means of gears and sprockets the movement of the table; fourth, to provide
eccentically journaled bars to hold the papers laid upon the table in a fast position
to prevent them from deplacing; and, finally, to provide a brush-roller operated
by means of pulleys and gears and whereby the paper-sheets, laid upon the table,
are bordered.
I attain these objects by the mechanism illustrated in the accompanying
drawing, in which:
Fig. 1 is a side-view of the entire machine;
Fig. 2 is a top-view of the machine and
Figs. 3-8 show the detailed-views of essential parts of the machine.
Similar letters refer to similar parts throughout the several views.
On the main-axle A is arranged the double-pulley B that is rotated by the wave
of translation of the manufactury and whereby the entire machine is operated.
On this same axle A are arranged first in the middle of it between the two
framing-parts a a, the great toothed gear C that meshes with the smaller gear-
wheel Darranged on the axle E; further, outwardly of the frame, the sprocket-
wheel g (see Figs. 1 and 2) that operates by means of a superposed chain the
sprocket h arranged on the axle i, situated horizontally above the frame of the
machine.
A smaller sprocket wheel 1 operating by means of a chain the sprocket m on the
axle o₁ is arranged on the same axle i that bears also the trundle 5 provided with
four seizer-arms.
On the axle o₁ are arranged, beside the said sprocket m a small sprocket o
operating by means of a chain the just as small sprocket p arranged on the roller r₁
and the wallover n with four rotating branches penetrating during their rotation
through a slit in the under plate of the vessel wherein the paper-sheets are
contained, and taking out of it one by one said sheets.
The roller r₁ operates by friction the superposed roller r, which rollers are

page_text: arranged before a slit in the aforesaid vessel formed by four vertical bars 3; on
the other side of the rollers is arranged an obliquely directed two-parted table 4.
(Figs. 1, 2 and 6) upon which the single sheets, after having been taken out of the
vessel by means of the wallover n, glide between the rollers r, r, to the rotating
seizers 5 that may alternately and mechanically open and shut their clutches to
hold and set free the paper-sheets.
The extremity of the axle E, operated by the main-axle A by means of the
toothed gear wheels C D bears the vertically turned crank F furnished at the
exterior extremity with a little pin, this latter being adapted to slide longitudinally
to and fro in the slot-hole G. The upper bar of this slot-hole is journaled in H
on the frame a and must, by consequence of the cranks rotating round the axis
of E, operate a pendulous motion round the journal H.
The said bar is further connected in J with the two-parted slide-block K L
(the construction of which is clearest to be seen from Fig. 2) horizontally moved
to and fro in the bows M N, disposed aside the frame u, by consequence of the
pendulous motion of I.
The construction of the said two-parted slide-block is as follows: A single slide-
block K is arranged in the bows M'N aside the frame a and moved in them to and
fro by means of the slot-hole G. On this slide-block K a second block is pivotly
fastened with it and pressed to the same by means of the plate-spring / riveted to
the slide block K.
The surfaces of contact between the blocks K and L are conically grooved at
their under side as to form in their unión a conical furrow in which the sharp edge
of the hereafter described eccentric bar P may enter from below and on account
of its conical edge may remove a little in horizontal direction the pivoted block L.
from the to- and fre-moving block K.
The pivoted block L has a vertically downwards directed brauch with a dovetail-
formed furrow in which the rectangular arm V O vertically adjustable is disposed.
(Figs. 1 and 2.) On account of its connection to the blocks K and L, the arm VO
is obliged to make a to- and fro-moving too. The horizontal branch O of the
rectangular arm has on its exterior extremity a little pin a adapted to catch in
corresponding holes of an hole-disks. The hole-disk S is fixed on the extremity of
the axle d, situated in the middle of the machine. On this axle d, is arranged a
little gear-pinion, that meshes with a gear pinion of the same diameter and
situated vertically under the aforesaid gear. At both sides of this second gear are
journaled two further gear pinions, every one meshing with the gear in their
middle and the bearing-studs of which bear beside the gear pinion small-sprockets k
operating by means of superposed chains just as small sprockets k, arranged
respectively on the axles d, and d, on the head respectively on the foot of the
machine.
21
These axles d, and dy hear, on each side gear pinions, resp. just as small as
the gear wheel z, on the axle d, and it is by means of the aforesaid gear pinions 1228
that the table is moved froin one side of the machine to the other. For this
purpose the table is provided with downwards prominent toothed bara that engage
said gear-wheels.
The table e is seen in Figs. 1 and 2, its detailed construction shown by Fig. 3 in
cross-section. It consists of a square-formed frame the alongsides of which show
downwards prominent toothed bars on each side to engage the above-named gear-
pinions on the axles d-d. The table has also a sidewards prominent flat border
to support the table at the beginning or at the end of its motion, when the toothed
bars engage only with the gear-wheels z, resp. z, upon the rollers R (Fig. 5)
journaled for this purpose in the frame-parts a a₁. In the middle part of the
machine the table rests either on the gear pinions ₁ z, or 21 23. On the axle E is
arranged on its extremity behind the crank F the eccentric bar P, journaled in Q
and the upper broad edge of which is conically sharpened like a knife, to enter
from below into the above named furrow formed by the contact of the two-parted
sliding blocks KL.

page_text: Between the framing-parts a a₁ of the machine are arranged on the aforesaid
axle-tree E four eccentric disks b and c of which the two, indicated by b, serve for
operating the bow-formed rod u destined to properly direct the single paper-sheets
on the table e; and the other two, indicated by the letter c. operate the rod.
destined to hold the papers directed by u on the table in their proper position
during the motion of the table.
The construction of the aforesaid rods is best seen in Fig. 2 in top-view and in
Fig. 7 and 8 on a greater scale in side-view and partly in top-view.
The rod u is pivotly arranged on the axle w₂ (Figs. 2 and 7) and therefore by.
consequence of its eccentrically arranging on the axle E, its exterior extremity
situated under the table 4 and the seizers 5 may be risen and sunk. The said
extremity of the rod u is formed by a cross-rod u₁ provided with oblique plates 9
along which the single 'sheets delivered out of the seizers, slide on the table e..
This cross-rod u, is adjustable arranged on account of the different seize and form
of letter-papers and covers.
"
The oblique plates 9 are two-parted and between their two parts can sink two,
pins arranged on the other rod, said pins being destined to fastly hold the papers,
in their proper position during the movement of the table e.
As may be seen by Fig. 7, the leading bar or rod x may communicate to the
motion of the table e on account of its journals being arranged in slot-holes in the
middle of the rod and at its extremity above the eccentric disks c. The rod a is
provided with a little toothed bar that may engage a gear pinion, arranged on
the axle d, and adapted to afford facilities for the proper sliding of the rod with
the moveable table e.
As may be seen by Fig. 6, the oblique table 4 upon which the paper-sheets slide
down to the table e, consists of two single plates, the upper one of which is fastly,
arranged and entirely flat, whilst the undermost plate is eccentrically arranged on
the roller "1 and provided with an upward prominent border to sustain and deliver.
at proper time the paper-sheets laid upon the upper plate.
In the foremost top of the two plates is a slit through which the hereafter
described seizers may turn to receive the sheets.
The trundle with four seizers 5 destined to take the paper-sheets from the
oblique table 4 and, when turning, to lay them on the moveable table e, is
represented on a greater scale in Fig. 4 in side-view and in Fig. 5 in front-view.
Each seizer has a fast tongue and a loose elastic one. Between both is disposed,
a tumbling-piece provided at each side with two salient pins. That of these pins,
serving for opening and closing the seizers, which goes first downward through the
two directing plates 9 of the above described cross-rod u₁ is hold by the said
oblique plates resp. receives in consequence of the oblique disposition of the
plates a pression downwards. The pins make in consequence of this pression a
quarter rotation of the tumbling-piece which takes now its place with its longer
side transversally. between the seizer-tongues removing them from each other. The
thus opened seizer rises now and receives, passing through the afore-mentioned slit.
of the table 4, the following sheet to be bordered.
Going out of the slit, the foremost pin, which are now horizontally besides each.
other, meets on both sides with a little crooked plate arranged on the table 4
(Figs. 4 and 5) whereby the pins are forced to rotate again in a quarter circle and "
to put themselves one above the other as to cause the seizer to be closed again and,
to keep fastly the paper-sheet brought in.
Thus, as soon as they have taken up the sheet, the seizers are mechanically,
closed and in the moment when they are to lay down the sheet on the table e, they
are selfacting opened.
The mechanism of operating the brush roller W to colour the border of the:
sheets is as follows:
On the axle E, outside of the frame, is arranged the rope-pulley T which
operates the small pulley U (Figs. 1 and 2) by means of an overlaid rope.

page_text: The pulley U is journaled in the frame of the machine and its gudgeon bears
still a gear pinion 24 engaging an other gear pinion z, on the axle on which is
situated the brush-roller which is turned quickly by means of the pulleys T and U
and the gear 24 25
The axle-tree of the brush-roller is hollow and punched at the place where the
brushes are disposed. The communication of colour to brushes by means of an
hollow axle is well known.
The operation of the mechanisms described heretofore and represented in the
annexed drawings I will now proceed to explain:
The discontinuous motion of the table e is effected as follows:
By the main-axle A of the machine is operated the axle E. The rotation of
this axle, operating the pendulous motion of the slot-hole G, effects the to- and fro-
moving of the slide-block K L, and the eccentric position of the bar P on the
same axle E produces by means of its sharp edged extremity and of the furrow
in the contact of the pivotly jointed sliding-blocks KL an alternately removing of
each other of said slide blocks. The pivotely joint block L bearing in its vertical
dovetail-furrow the adjustable rectangular branch V O may be removed from the
slide-block K by means of the eccentric bar P and pressed again it by means of
the plate-spring f.
It is clear that the branch VO communicates to this removing and pressing; and
being provided on its exterior extremity of the horizontal arm with a pin adapted
to catch in holes of the disk S, it may catch in said holes when pressed towards K,
and may be put out of the holes when removed from K.
Being forced to communicate to the to- and fro-moving of the slide-block, the
pin arranged on the extremity of O can draw with itself the disk S when it
catches in the holes as to turn the disk and in consequence thereof the axle-tree
whereon-the-disk- is mounted. After-having-on-its_return_motion turned the
pulley S the pin must be delivered out of the hole and this is done in the following
manner.
As soon as the crank F mounted on the axle E has reached the end of its stroke
at the right, which takes place together with the termination of the backwards
motion respectively the beginning of the forwards motion of the slide-block K the
éccentric bar P is disposed as represented by Fig. 1. Its upper edge has pressed.
itself between K and L and removed them from each other after having nastered]
the pression of the spring (Fig. 2) so that L and with it the rectangular arm O
are withdrawn a little from K in horizontal direction whereby the pin of the arm V
respectively O is put out of the hole of the disk S. As soon as the latter has
come out of the disk and this is free, two joint spring-acted pins squeeze from
behind into the two neighbouring holes of the disk that is in that which the pin
just has left and in the next following in order to prevent the disk from making
an other motion as produced by the pin on the arm O.
Those elastic pins are not represented in the drawings.
The bole-disk S is consequently stopped till the pins in its backwards motion
springs into the next following hole and drives the pin which is at this place and with
this the second one, entered from the back of the disk, out so that the disk may
turn again.
The axle di communicates to the periodical turning of the disk S the latter
being mounted on it.
This motion is now transferred from the axle d, to the axles d, and d, by means
of the three little gear pinions mounted below the gear 21 on the axle d₁ and the
middle one of which engages said wheel 2, and by means of the sprockets k
journaled on the same gudgeons of the said little gears arranged aside, said
sprockets k, operating by overlaid chains the small sprockets k, and k, arranged
respectively on the axles d, and d₂.
Thus the toothed wheel 21 2 2 mounted respectively on the axles d₁ d, d, move
in the same direction and with the same velocity and the table e engaging by its

page_text: downwards directed toothed bars said gears, is forced to communicate to said
motion.
The selfacting putting of the paper-sheets to be bordered is effected as
follows:
The paper-sheets or letter-covers are put in piles on the furrowed plate 2
(Figs. 1 and 2) fixed above the side-frames by supports 1 and between the bars 3
that are adjustable according to the size and shape of the papers to be bordered.
Through one of said furrows in the plate 2 turns the wallover n and each branch
of it takes a single sheet,under the pile and drives it between the leading rollers r
wherefrom the sheet reaches the oblique two-parted table 4. The paper-sheet glides
on said table down till it lies with one coin in the belowest point of the table where
it is stopped by the upright border of the under eccentrically mounted plate of the
table 4.
In the right moment, when one of the seizers 5 turns through the slit arranged in
the undermost part of the table, the upright border goes down and the sheet is taken
by the seizer the tongues of which are closed in the same moment. The seizer
turns and, when arriving above the moveable table e and between the oblique
directed plates 9 of the cross-rod u, sinking in that moment, the tongues of the
seizer are opened by means of the heart-piece and of its sidewards arranged pins,
and the paper-sheet, directed by the aforesaid oblique plates 9, is let fallen on the
table.
After having fallen, the sheet is immediately kept fastly on the table by the two
vertical pins of the rod a sinking in that moment and communicating to the
movement of the table on account of its above described slot-holes, toothed bar and
gear-pinion, (Fig. 7).
The angle of transposition of the eccentric actuating the directing rod u as to
the eccentric of the rod a keeping the sheets fastly on the table e, is about
180 degrees, so that, when the directing rod u has laid the paper sheets in their
proper position on the table e, the rod sinks immediately after and the elastic
pins arranged on its foremost double end press on the sheet just fallen in order to
prevent it from déplacing.
At the same time the rod u rises again and the table makes an other corresponding
jerk forwards taking with itself the sheet hold by the leading-rod x.
When the table e and with it the rod a have finished the forwards motion, the
rod x rises again by means of its eccenter and, when discharged from the gear a
and in consequence of being joint to the side-frame a by means of a spring, goes
immediately backwards as to sink in the right moment on the following paper
sheet.
Now I may still be permitted to explain the operation of of colouring.
As soon as the foremost border of the table 4 and with it the paper-sheet laid
upon it, have arrived in the middle of the machine, they pass under a quickly
rotating brush-roller W (Figs. 1 and 2) actuated by means of the rope-pulleys T Ú
and the gear wheels 24-
The shaft of the brush-roller beeing hollow and punched at the place, where the
brushes are disposed, the colour is communicated to the brushes which spread
themselves on the paper-sheets.
Having 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 I
claim is.
