My invention relates to an improved machine for the manufacture of envelopes
or bags, and consists. Firstly Of mechanism for gumming the sealed flaps of
envelope blanks, and laying them out to dry and Secondly, Of mechanism for
gumming printing or embossing, folding and packing the same.
The whole of the said mechanism being embodied in a single machine.
My invention consists, Firstly, To the means employed in gumming the sealed
flaps of envelope blanks which are placed for that purpose upon a rising and falling
table.
The gum is placed into vessels or boxes provided with movable feeders shaped
and formed to correspond with that part of the envelope to receive the gum. The
feeder is caused to rise at the proper time and come into contact with the underside
of a moving instrument called a gummer, which is also formed to correspond with
the shape of the envelope flap, which gummer after being supplied with gum moves
laterally over one or more bars or scrapers whereby the superfluous gum´is removed
and returns into the gum véisel;

page_text: The rising and falling table upon which the shaped sheets or envelope blanks are
placed then ascends bringing the uppermost sheet or blank into contact with the
gummer from which it receives a given quantity.
The table then descends leaving the gummed sheet sticking to the gummer but
held and supported in a horizontal position by one or more movable arms or fingers,
until it is removed by a pair of nippers attached to a reciprocatory carriage. The
nippers are fastened to a rocking shaft which is caused to rock at a given time by
the reciprocatory carriage bringing a lever on the end of the rocking shaft into
position to be operated upon by a rising pin which causes the said shaft to partially
turn around whereby the nippers close and seizes hold of the gummed sheet which
it transfers and deposits upon a travelling board having an intermittant forward
motion given it by rollers actuated by ratchet wheel and catch.
The sheets with the gummed flaps are placed upon this table one after another,
and the table travels at such a speed that the gummed part of one sheet is clear of
the gummed part of next sheet. When the said travelling board is filled with
gummed blanks it is removed and placed into a rack for the gummed parts to dry
and another board substituted and filled in like manner. When the nippers take
hold of a blank they are locked so that they cannot leave hold thereof until the
proper time, and this is effected by means of a catch dropping into a notch (formed
in the lever on the end of the rocking shaft) immediately on the nippers closing
upon the blank the said catch being removed from its notch when the blank has
been carried to its proper destination, by means of a rising pin.
Secondly. My invention relates to the means employed in gumming that part of
the envelope blank which it is required to be folded before it is dry and made to
stick to the parts intended, so as to form an envelope or bag also to the means
for printing or embossing and folding same and to packing the envelopes when
'folded'
For these purposes I take a given quantity say 25, 50 or 100 of the blanks
which have already had their flaps gummed and dried and these I place upon
another rising and falling table which blanks are gummed by another gumming
apparatus similar to the one already described. Another pair of nippers attached
to a bar on another reciprocatory carriage are employed which transfers the
gummed blank upon another table under which is a type bed caused to ascend
lifting the upper table and the gummed sheet resting thereon into contact with a
fixed beam by which means the type prints or impresses upon the gummed sheet
any required name or device. The table then descends when a second pair of
nippers (similar to the one already described and attached to another bar on the
same reciprocatory carriage) seizes hold of the said sheet (the first pair of nippers
upon the
are here receeding taking hold of another gummed sheet) and deposits it
folding table, after which they release their hold of the sheet.
A die or form of the size and shape of the envelope then descends upon the sheet
or blank when a series of four sliding plates are caused to slide over and upon the
edges projecting past the die, which are folded thereon thereby forming an envelope
or bag, and simultaneously with such movements the die or form is pressed
upwards against the underside of the sliding plates thereby causing the gummed
parts of the envelope to stick where intended. The four sliding plates then recede
and the die with the envelope thereon ascends when another or third pair of
nippers attached to the reciprocatory carriage comes and seizes hold of what is now
the top
an envelope which it removes from the die or form and deposits over
of a box.
"
The nippers then release their hold of the envelope which is pressed or pushed
into the box by a plunger or presser descending just at the time. This box is
provided with a loose bottom moved upwards by a spring or equivalent the said
box also having two of its sides hinged and formed with overlapping edges so that
when each envelope has been pushed into the box the hinged sides open out wide
enough to allow the envelope to be placed into the box, after which the hinged

page_text: sides return again, the overlapping edges thereof holding the envelopes down in a
compact form and prevented from rising or springing up as would be the case
without them.
C
The whole of the movements and motions of the various parts herein mentioned
are effected by a series of levers and rods operated principally by vertical levers
provided with slots or cam grooves and the printing type is supplied with ink by
rollers operated by the same means,

shafts 2° and 2 Each of the pins 6 and 6° carry three friction rollers, 6ª carrying
two friction rollers and 6° carrys four friction rollers which several rollers work
within the slots of the slotted levers 8. 9. 12. 13. 14. 15, 16. 17. 18, 19. 20. 21, 22, 23,
and 24 giving all of them a rocking motion on their respective pivots hereinafter
explained 7 and 7º are two bent rods or levers forked at one end rocking on their
pivots 7 and 7° caused to move upward, the upward movement of the pins 6° and 6°
coming in contact with the underside of the brackets 7 and 7° which brackets are
bolted to the rods 7 and 7b respectively and immediately above the said pins, the
said rods 7 and 7b descending by their own weight when released by the pins.
8 is a slotted lever forked at one end, and having a rocking motion on the pivot 8,
this lever gives a lateral motion to the bar 8. Two vertical spindles 8° and 8d have
each a plate fixed on the top, and each of these spindles have also a small friction
roller pivoted in the slot through which the bar 8b slides. These said spindles 8°
and 8 have an upward motion imparted to them by the inclined parts of the
bar 8b pushing against the friction rollers; 8° and 8' are two fixings having a holė
in each, which fixings together with corresponding holes in the top plate of the
framework form guides for the spindles 8 and 8, the said fixings being fastened
to the underside of the top plate of the framework. 8" and 8" are two springs

page_text: placed respectively on the spindles 8° and 8d between the fast collars on the bottom
of each spindle and the underside of each fixing, these springs causing- the said
spindles to resume their normal position when allowed to do so by the motion of
the bar 8. 9 is a slotted lever forked at one end, somewhat similar to the lever 8
and having a rocking motion on the pivot 9 and giving a lateral motion to the
bar 9b. Six vertical spindles 9°, 9ª, 9° 91, 98 and 9h have each a plate fastened on
the top, and each of them have also a friction roller pivoted in the slot through which
the bar 9 slides. These six spindles have an upward motion given to them by the
inclined parts of the bar 9b pushing against the friction rollers. '9³ and 9* are two
fixings, 9' having two holes and 9 having four holes in at, these holes together with
corresponding holes in top plate of the framework form guides for the six vertical
spindles ´9º 9ª, 9° 9° 9° and 9h the said fixings 9³ and 9* being fastened to the
underside of the top plate of the framework. 9' 9" 9" 9° 9° and 9³ are six springs
placed on the said six spindles between the fast collars on the bottom of. each
spindle and the underside of the fixings 91 and 9*. These springs cause the said
spindles to resume their normal position "when allowed to do so by the motion of
the bar 9b. 10 is a peculiar shaped fixing bolted to and therefore having a similar
motion to the upright bar or shaft 2. Four slotted levers 10° 10° 10° and 10°
having a rocking motion on their respective pivots 10 10 10 and 10° are
employed for operating the folding mechanism. 10° 10' 10 and 10' are four pins
attached to the fixing 10, and each have a friction roller placed thereon. These
rollers work up and down in the slots of the levers 10° 10° 10° and 10d which give
them their rocking motion. 10" is a pawl or catch pivoted at 10" to the fixing 10
and therefore having a similar upward and downward motion to the said fixing, a
pin 10° projects from the upper end of the pawl or catch 10" which pin slides up
and down in the irregular slot formed in the plate 11° (described hereafter) by
the upward and downward motion of the said fixing 10. A small flat spring 10°
is attached to the lower end of the pawl or catch 10 and presses against a pin or
stud in the fixing 10, which causes the upper end of the pawl or catch 10m to be
pressed towards the rack 11d also described hereafter;. 10s is a small pin or stud
near the top of the slotted lever 10 to which is attached a cord or chain running
around the grooved pulley 10 and fastened at its other end to the hinged
side of the receiving box 36* hereinafter explained. 11 is a vertical spindle
at the top of which is fixed a plate (the size and shape of the envelope
when folded) which forms the moveable bottom of the receiving box. 11 is
a fixing bolted to the underside of the top plate of the framework, and having
a hole in it, which together with a corresponding hole in the top plate
of the framework forms a guide for spindle 11. A spring 11b is placed
upon the said spindle 11, between the fast collar and the collar of the sliding
bar 11, the upper end of which bar is guided by a hole in the fixing 11°. A fine
toothed rack 11ª is fixed against the sliding bar 11° and a plate 11° is fixed in a
vertical position against the fixing 11 which plate has an irregular slot formed
therein, and in which the pin 10° works. A pin 11' is fixed through the fast
collar on the spindle 11, whilst 11s is a grooved pulley pivoted to the fixing 11.
A cord or chain is attached to the pin 11' and runs around the pulley 118 having
the weight 11 attached to the other end of it. The sliding bar 11° has an inter-
mittent upward motion imparted to it by the pawl or catch 10 which engages the
ack 11d twice for a short distance each time in its upward movement, each
pward movement of the said sliding bar 11° tends to press upwards the spindle 11
by the spring 11b and thereby squeezes the envelopes which are in the receiving
box into a compact form. The weight 11" causes the said spindle 11 to be kept as
igh as possible. 12 is a slotted lever having a rocking motion on the pivot 8
nd which gives a rocking motion to the lever 12b by means of the irregular
haped connecting rod 12. The axle 12° on which the lever 12b is pivoted has
wo friction pulleys 12 and 12" keyed upon it, 12ª is a pawl or catch pivoted on
he lever 12 and 12° is a ratchet wheel attached to the friction pulley 12. Two
angers 12 and 12' are bolted to the underside of the top plate of the framework,

page_text: and carry the axle 12° with its accessories, 12k is a drop catch pivoted to the
hanger 12' and having a projection which drops against the ratchet wheel 12°
thereby preventing it from going backwards. 13 is a slotted lever having a
rocking motion on a pivot fixed in the fixing 4, and giving a rocking motion to the
lever 13b through the bent connecting rod 13. A hanger 13° is bolted to the
underside of the top plate of the framework and carrying a stud on which the
lever 13 is pivoted, 13ª is a flanged wheel whose flange forms a ratchet wheel
with twenty five, or any other suitable number of teeth, this wheel 13ª revolves
easily on the said stud, and has a piece cut out of its rim just large enough to
allow one end of the pin 3' to pass through it. 13° is a pawl or catch pivoted on
the lever 13b and engages within the teeth on the flanged wheel 13ª. A drop
catch 13' is pivoted on the hanger 13° and having a pin or projection fixed there
which drops against the teeth of the flanged wheel 134 thereby preventing it from
moving backwards. Now when the lever 3 is lifted to the top of its stroke it puts
into gear the three cog wheels 2ª, 2° and 3* (which sets the machine in motion) 1
and lifts the pin 3' through the notch in the rim of the flanged wheel 13d and
when the lever 13b has had one to and fro motion, it will have pushed the said
ratchet wheel forwards one tooth thereby securing or holding the pin 3' in the
same position, until the lever 13b has had twenty five to and fro motions, when
the said notch comes round at the twenty fifth motion and thereby allows the
pin 3' to drop through the said notch and be released and thereby allowing the
lever 3 to descend or fall; and thus throw out of gear the cog wheels 2.2 and 3*
which operation stops the machine.
14 is a slotted lever having a rocking motion on a pivot fixed in the fixing 4,
and giving a rocking motion to the compound lever 14 on the pivots 14° and 144
by means of the connecting rod 14. A fixing 14° is bolted to the compound

Specification consisting of two slide bars and a cross bar-14h is an adjustable
cross bar fastened to the said carriage 14 and carries a gripping arrangement,
details of which are shown in Fig 10, the rocking motion of the compound lever 14°
gives to the said carriage 145. a horizontally reciprocatory motion within the
grooves of the fixings 27 and 27*.
15 is a slotted lever having a rocking motion on a pivot fixed in the fixing 4;
and imparts to the L shaped lever 15° a rocking motion on the pivot 15" which
said lever 15 gives a vertically reciprocatory motion to the cross bar 15' by means
of the vertical connecting rod 154. An adjustable pin 15° is fixed at the longer
end of the lever 15, and to this pin is attached the lower end of the connecting
rod 15ª the upper end of said rod being pivoted at 15° to the cross bar 15. A cross
bar 15 is connected with the cross bar 15' by the two vertical spindles 15th and 15'
and 15* is a bracket carrying a loose pulley 151 this bracket being bolted to the
cross bar 15 receives through the said spindles 15 and 15 the same motion as the
cross bar 15' and these said spindles are guided by holes in the grooved fixings
27 and 27*.
A slotted lever 16 is employed having a rocking motion on a pivot secured in
the fixing 4 giving a lateral motion to and fro to the rod 16, one end of which rod
slides through a slot in the fixing 16" this fixing being bolted down to the bottom
plate of the framework. 16° is a bracket bolted to, and therefore receiving the
same motion as the rod 16, and 16ª is a vertical spindle or rocking shaft working

fastened at one end to a pin in the bracket 16° (which bracket is bolted to the
bottom plate of the framework.) and at the other end to a cord or chain which
said cord or chain is fastened to a small pin in the said spindle or rocking
shaft 16. A moveable finger or arm 16' mentioned in the Provisional Specification
is fixed to the top of the said spindle or rocking shaft 16ª and is employed for

page_text: purposes herein explained. The shaft 16ª is made to rock or vibrate by the
bracket 16° coming in contact with the pin 16, the spring 16h being pulled out by
the said motion and this spring 16" causes the shaft 16 to resume its normal
position when the bracket 16° recedes. The finger or arm 16' being fixed on top
of the said spindle or rocking shaft 16ª it will of course receive the same rocking
motion.
17 is another slotted lever having a rocking motion on a pivot fixed in the

to the plate 17 each of which brackets have a loose pulley pivoted in a fork at one
end. 17 17, 17 and 17* are four adjustable guides fastened to the plate 17 to
keep the blanks in their proper position.
The mechanism which comprises the said rising and falling table is caused to rise
by the forked end of the rod 17ª being lifted up by the pin 17° coming in contact (in
its to and fro motion) with the underside of the slanting projection 17, and when
the said pin 17° has got beyond the said projection 17 the rod 17ª is allowed to
fall (bringing with it the said table 17") and the said pin 17° in its backward
motion slides over the top side of the projection 17' which said pin then drops into
its place again ready to repeat the motion.
18 is another slotted lever having a rocking motion on a pivot fixed in the
fixing 4 and giving a rocking motion to the compound lever 18d by means of the
connecting rod 18. A bracket 18 is bolted to the said compound lever 18d which

which the thumb screw 23 passes. 23 is a bar or plunger connected with the
plate 23 by the vertical spindle 23" which bar or plunger carrys, one at each end
the two adjustable flat springs 23 and 23. The die or form attached: to the
rod 23' and the bar or plunger 23 have of course the same vertically reciprocatory
motion as the cross bar 23' because they are both connected with it.
-24 is also a slotted lever having a rocking motion on a pivot fixed in the fixing 4*

page_text: and which gives a rocking motion to the compound lever 244 on its pivots 24°
and 24 through the connecting rod 24. A bracket 24 is bolted to the compound
lever 24d and which carries an adjustable pin 24 to which pin is pivoted one end
of the connecting rod 24. The two slide bars 24 and 24h which together with
the three adjustable cross bars 24', 24 and 24' form the second reciprocatory
carriage mentioned in the Provisional Specification, and employed for fetching and
carrying the blanks and envelopes, the said carriage having horizontal reciprocatory
motion imparted to it by the compound lever 24ª along the grooves in the
fixings 27 and 27°. Each of the adjustable cross bars 24 24 and 24' have a
gripping arrangement attached to them similar to that shown in detail in Fig 10.
25.is a small vertical spindle attached to the cross bar 25b and this bar is
connected to another cross bar 25' by the two vertical spindles 25ª and 25°, and on
the spindle 25 a pin 25° is fixed. The dipper or moveable feeder 25 (mentioned
in the Provisional Specification) is fastened to the cross bar 25 and has a vertical
reciprocatory motion given to it by the forked end of the rod or lever 7 engaging
the pin 25°. The spindles 254 and 25° being guided in their vertical motion by
holes in top plate of the framework, and the spindle 25 is guided by a hole in the
bracket 25 which bracket is bolted to the end framework.
26 is another small vertical spindle attached to the cross bar 26 and this bar is
connected with another cross bar 26' by the two vertical spindles 26ª and 26° a
pin 26° being fixed in the spindle 26. The dipper or feeder 26% of the second part
of machine is fastened to the cross bar 26, this dipper or feeder being connected
(through the said cross bars and spindles) with pin 26° receives therefrom_a
vertical reciprocatory motion by means of the forked end of the rod or lever 7.
The spindles 26 and 26° are guided in their vertical motion by holes in the top
plate of the framework and spindle 26 by a hole in bracket 26ª which bracket is
bolted to the end framework
27, 27* 27° and 27° are four longitudinally grooved fixings bolted down to the
top plate of the framework, and in which grooves the reciprocatory carriages 14"
18 22 and the parts 24 and 24" slide.
28 is a cross bar pivoted at each end to the grooved fixings 27 and 27" and
having a bent bar 28" fastened to the centre of it, and a straight bar 28' attached
to one end of it. 28° is a small lever having a rocking motion on the pivot 28ª
fixed in the grooved fixing 27°, and 28° is a bar sliding horizontally and supported
by two set screws fastened to the grooved fixing 27 one end of the said bar is
pivoted to the end of the lever 28° and the other end has a small flat spring 28º
pressing against it which spring is fixed in the grooved fixing 27", and 28" is a pin
projecting from the sliding bar 28°. The said bar 28° is pushed in one direction by
the spring 28 and in the other direction by the pin 18' pushing against the pin 28
alternately. The bars 28* and 28 have an intermittent rocking motion on the pivots
of the bar 28, effected by the table 17ª rising and falling, and, as the sliding bar 28°
is allowed to move forwards before the table 17ª rises, the straight bar 28b (when it
is at the top of its stroke) is held there by a notch on the lever 28° until the sliding
bar 28 is moved backwards by the pin 18' coming in contact with the pin 28*
pulling away the notch and thereby allowing the bars 28 and 28 to fall back again.
The end of the bent bar 28° rests upon the blanks on the table 17" and when this table
rises, the end of the said bent bar pushes the uppermost blank against the guides 17
and 17' which prevents the gummer from retaining more than one blank at once.
29 is a horizontal shaft revolving on its centres 29" and 29 and having two
india rubber friction rings 29° and 29ª on it immediately over the two friction
pulleys 12 and 12" on the axle 12°.
30 is the travelling board mentioned in the Provisional Specification, and which
has an intermittent forward motion given to it by being held between the friction
rings 29° and 29ª on the shaft 29, and the friction pulleys 12" and 12, which
pulleys are caused to revolve intermittently by the pawl or catch 12ª on the
lever 12 engaging the ratchet wheel 12. The gum boxes 31 and 31 of the first
and second parts of the machine respectively are bolted to the top plate of the
.

page_text: framework, the box 31 having a clear space underneath as shown in the Drawings'
(see Fig 8) to allow the travelling board 30 to pass under it. 31b and 31° are the
scrapers, which may be made adjustable or fixed in the gum boxes.
32 is the type bed upon which the type or die 32ª is fixed. 32" and 32° are two
vertical spindles fixed to the underside of the type bed 32, and two spiral
springs 32' and 32 are placed upon the spindles 32 and 32° between the fast
collars on the bottom of each, and the undersides of the two fixings 32° and 32d
which fixings are bolted, one on each side of, and at the top of the upright bar or
shaft 2 and thereby partially fixing the said type bed 32 to the top of the upright
bar or shaft 2, consequently both of them will have the same vertical motion.
32 and 32 are two adjustable guides fixed to the top side of the type bed 32.
33. is a cross bar which together with the adjustable supports 33, 33b, 33°,
and 33d form the table (mentioned in the Provisional Specification) upon which the
blanks are deposited to be printed. The supports 33 and 33° having guide pins
fixed at the ends and are fastened to the bar 33, as also is the support 33" the
support 33 being fastened to the top plate of the framework. 33° and 33' are two
vertical spindles which are fixed to the underside of the cross bar 33, and are
guided by holes in the top plate of the framework and corresponding holes in
grooved fixings 20 and 20. Two springs 33 and 33 are placed on the said
spindles between the fast collars on the bottom of each and the underside of the
top plate of the framework.
34 is a beam fixed rigidly to the top of the grooved fixings 27 and 27° and
immediately over the type bed 32 and the cross bar 33. A block 34* is fixed to
the underside of the beam 34 forming a buffer against which the type bed and
table are pressed which operation prints or embosses the required device upon the
envelope blank. The return stroke of the said operation is as follows; the upright
bar or shaft 2 descending brings with it the type bed 32, because the two
springs 32 and 32s tend to keep it close to the top of the said shaft 2º, the two
springs 33 and 33 also tend to keep the cross bar 33 close upon the type bed 32,
therefore they all descend together until the cross bar 33 falls upon the grooved
fixings 20 and 20" where it stops and the type bed 32 and the shaft 2" descend
together until the said type bed 32 rests upon the fixing 4 where it stops and the
shaft 2 descending still further to the bottom of its stroke leaves the said type
béd 32 but holds it down firmly by compressing the springs 32' and 32* whilst the
type is receiving its quota of ink from the rollers 20 and 20'
.35 is the folding table, or the table upon which the blanks are folded and it is
bolted down to the top plate of the framework, which table is provided with four
slides; and 35° 35° 35° and 35ª are four slide blocks, to which are attached the
four sliding folding plates 35° 35', 35 and 35" respectively, the said alide blocks
having each a slot into which are inserted the top ends of the slotted levers 10°.
10° 10° and 10d from which levers the said blocks receive their sliding motion.
35 (see Fig 12) is a block upon which the die or form descends, and to the under-
side of which the two spindles 35 and 35¹ are fixed. 35 and 35" are two springs
attached at one end to the two spindles 35 and 35¹ and at their other ends to the
two pins on the plate 35º.
.
When the envelope is folded the block 35" is pressed upwards against the under-
side of the die or form by the fixing 10 coming in contact with the plate 35" and
thereby equeezing the envelope and causing the gummed parts to stick where
intended. 35 35 35 and 35" are four adjustable guides which keep the blank in
its proper position, and 35* is a peg in the slide block 35°.
36, 36 and 36 are three facings on the top framework of the machine two of
which viz-36 and 36° are grooved,- 36 and 36d are two adjustable plates
each having a longitudinal groove on the top and a cross wise tongue underneath
at each end, these tongues fit within the grooves in the facings 36 and 36.
Four adjustable fixings 36" 36", 36" and 36 (which form two sides of the
receiving box) having each a tongue on the underside, which tongues fit in the
longitudinal grooves of the plates 36° and 36º, whilst 36³ and 36 are two plates

page_text: pivoted at the bottom to the four fixings 36° 36', 36" and 36" (these plates form
the hinged sides of the receiving box) and each having a small hook at the back
on which to fasten the ends of the cords or chains, the other ends of which are
fastened at 10 and 35. There are also employed two Ŀ sectioned plates 36¹
and 36 fastened on the tops of the plates 36 and 36* respectively, forming the
overlapping edges of the hinged sides of the receiving box mentioned in the
Provisional Specification. When the folded envelope is deposited upon the receiving
box, the hinged sides are closed at the time, and the plunger 23* coming down
upon it holds it there until the said hinged sides are opened by the lever 10 pulling
one cord or chain and the slide block 35° pulling the other cord or chain which
operation opens the hinged sides and allows the springs 23' and 23 to press
corners. of the envelope into the box, and when the lever 10 and the slide block 35°
allow the cords or chains to slacken, the hinged sides of the box are closed by two
flat springs attached at one end to pins or projections in the fixings 365 and 36";
and their other ends pressing against hooks or projections attached to the ends of
the hinged plates 36 and 36*, and when the plunger rises, the overlapping edges
keep the envelope down in the box.
the
To empty the said receiving box when required, the thumb screw 23" is turned
lineable with the slot in the plate 23" which allows the said plate 23™ to be turned
up on its hinges, which operation lifts the bar 23* out of the way and thus allows ·
the envelopes or bags to be taken out
37 is a rocking shaft (see Fig 10) which is supported by the two eyes 37* and
37; attached to the cross bar 14 and 37° is a hanger fastened to the underside of
the cross bar 14 and close against the carriage slide 14. A tongue or lip 37ª is
fixed to the rocking shaft 37 which tongue or lip together with the bracket 37°
attached to the cross bar 14" forms a pair of nippers mentioned in the Provisional
Specification. 37' is a small crank lever fixed on the end of the rocking shaft 37,
to which lever is pivoted the vertical rod 37″ one end of which rod is guided by
a slot in the hanger 37° A peculiar shaped catch 37 is pivoted at 371 on the
banger 37, to this catch is fixed a flat spring 37 which presses against a
pin 37 fixed to the rod 37 which flat spring when the nippers are closed as shown
in Fig 10 causes one end of the catch 37 to be pressed upwards and butt against
the notch or projection 37* on the rocking shaft 37 which notch serves to keep the
nippers closed. When the nippers are closed as shown in Fig 10, the carriage 14"
has carried the cross bar 146 with the gripping arrangements attached to it
immediately over the vertical spindle 8ª which spindle is now at the top of its
stroke having pushed the vertical rod 37 upwards, thereby closing the nippers;
the spindle 8d now descends to the bottom of its stroke, and the carriage 14
recedes, carrying with it the gripping arrangement and stops with the catch 37
immediately over the spindle 8° (which is also at the bottom of its stroke, or else
the catch in its present position with nippers closed would not go over the platė).
When the said spindle 8° rises and pushes one end of the catch upwards thereby
releasing the other end from the notch 37 and allowing the spring 37* to press
downwards the rod 37 which operation opens the nippers. This description of the
gripping arrangement will also apply to the three other gripping arrangements
attached to the cross bars 24, 24*, and 24'.
I will now commence to describe the various movements of the first part or seal
flap gumming and drying part of the machine, and for that purpose I take a given.

upon the table 17" between the guides 17, 17, 17" and 17 and to do this the.
bar 28 must be lifted up and then put down again upon the blanks, I then push
the travelling board 30 between friction pulleys 12 and 12*, and the friction
rings 29 and 29d on the shaft 29 and under the pulleys attached to the
brackets 15 17° and 17° and as far as the edge of the table 17, I then start the.
machine by lifting the lever 3 to the top of the slot 3 and setting the shaft 2 in.
motion, the upright bar or shaft 2° being now at the top of its stroke begins to.

page_text: descend, which causes the dipper or feeder 25 to fall into the gum in the gum
box 31, it having wet the gummer 18 with gum.
The carriage 18 now takes the gummer 18h over the scrapers 31° and stops with
the gummer immediately over that part of the blanks which has to be gummed,
and allows the lever 28° to move into position to catch the bar 28, and
simultaneously with this movement the spindle 8° is caused to fall, the travelling
board 30 is moved its required distance forward, and the rocking lever 13° is
brought into position to repeat its work,-The table 17" now ascends, pushing the
end of the bar 28" upwards and slightly forwards, this movement causing the
uppermost blank to be kept against the guides 17 and 17* and pressing the
uppermost blank against the gummer 18¹, the said table will now descend leaving
the said blank sticking to the gummer, the bar 28 which is now at the top of its
stroke is held there by a notch on the rocking lever 28° and thereby supporting
the bar 28º.
Simultaneously with this movement the bracket 15 is caused to ascend to the
top of its stroke. The carriage 14 now begins to move forward during which
movement the end of the finger or arm 16' moves under the blank left sticking to
the gummer and supports the other end of it until the carriage 14 brings the
cross bar 14h with the gripping arrangement attached to it to the end of its stroke
when the vertical bar 37 of the gripping arrangement comes immediately over
the plate on the spindle 8d which spindle is now caused to rise, thereby pushing
up the bar 37 and thus closing the pair of nippers upon the blank and holding it
fast. The upright bar or shaft 2° being now at the bottom of its stroke commences.
to rise, causing the spindle 8d to fall, the notch and catch of the gripping
arrangement still keeping the nippers closed upon the blank. The carriage
14 now recedes to its former position carrying with it the gummed blank, and
also carrying the catch 37 immediately over the plate on the spindle 8°; and the
arm or finger 16' is at this time also resuming its former position against the gum
box 31. The bracket 15* now descends upon the blank thus holding it down upon
the travelling board 30, the nippers still holding one end of the blank, and
simultaneously with this movement the mechanism which moves the table 17" is
resuming its former position ready to repeat its motion. The carriage 18 now
recedes to its former position taking with it the gummer 18; and the pin 18' coming
in contact with pin 28 pulls the notch on the lever 28° away from the end of
the bar 28 and thus allows the end of the bar 28 to drop upon the remaining
blanks on the table 17ª, and simultaneously with this movement the flanged
wheel 13ª is moved forward one tooth. The rocking lever 12b also resumes its
former position, and the spindle 8° is also moved upwards pushing with it the end
of the catch 37 and thus opening the nippers, and releasing the blank which is
now held upon the board 30 by the pulley attached to the bracket 15. The
dipper or feeder is now caused to rise out of the gum in the gum box to the top
of its stroke; and thus wetting the gummer again ready for another movement.
The upright bar or shaft 2° being now at the top of its stroke, it is ready to repeat
the operation.
To describe the various movements of the Second or folding part of the machine,
it will be best to suppose there is a blank on each of the tables 33 and 35, and an
envelope or bag folded upon the die or form, I then take a given quantity of
envelope blanks, say 25, 50, or 100, that have already had their seal flaps gummed
and dried, and place them upon the table 21" between the guides 21P 21, 21, and 21*,
I then start the machine in the manner previously described, and the upright bar 5
or shaft 2 then begins to descend causing the dipper or feeder 26" to fall into the
gum in the gum box 31* it having wet the gummer 22h with guin. The type
bed 32 and the cross bar 33 with the printed blank upon it also descending with
the bar or shaft 2", and simultaneously with these movements the fixing 10 leaves
the plate 35º thereby taking the pressure off the die or form on the folding table 35, 5
and pulling the pawl or catch 10 down with it, and thereby taking the pressure off
the bar or plunger 23*.
:

page_text: The carriage 22 now moves forward carrying with it the gummer 22h over the
scrapers 31° and stops with the gummer 22 immediately over that part of the
blanks which has to be gummed, and simultaneously with this movement
the sliding folding plates 35°, 35, 35 and 35 recede or open out, (in order to
allow the die or form to rise) and thereby slackening the cords or chains which
hold the hinged sides of the receiving box open and thus allowing them to close.
The table 21 now ascends, pressing the uppermost blank against the gummer 22
after which the.table descends leaving the said blank sticking to the gummer.
The cross bar 33 with the printed blank upon it is now left resting upon the
grooved fixings 20 and 20 by the upright bar or shaft 2ª descending, and
simultaneously with these movements the cross bar. 23' is caused to. rise carrying
with it the bar or plunger 23, and the die or form with the folded envelope upon
it; and also the vertical spindles 9°. 9d and 9º are caused to descend or fall. The
sliding bars 245 and 24h which together with the three cross bars 24', 24* and 24'
form the reciprocatory carriage mentioned in the Provisional Specification having
now begun to advance, proceeds to the end of its stroke carrying the vertical
bars 37% of the three gripping arrangements over and above the plates of the three
vertical spindles 9° 9° and 9 respectively, the nippers also coming into position to
seize their particular blanks and envelope. The type bed 32 also descending with
the upright bar or shaft 2 has now been left resting, upon the fixing 4°. The
inking rollers 20 and 20' which have been moving slowly over the circular inking
table 19 during the greater part of this downward movement of the bar or
shaft 2 now move over the die or type 32" (which is at present on a level with
the said rollers and inking table) giving to it its necessary amount of ink, and
simultaneously with this movement the circular inking table 19¹ and inking
roller 20 are caused to move partially round, and the three vertical spindles 9*, 98,
and 9ª are caused to ascend and push upwards the three bars 37% of the three
gripping arrangements attached to the three cross bars 24 24 and 24' thereby
closing the nippers of each upon the folded envelope, the gummed and printed or
embossed blank, and the gummed blank still sticking to the gummer respectively:
The upright bar or shaft 2 being now at the bottom of its stroke begins to rise
again causing the three spindles 9°, 9ª. and 9¹ to fall, the notches and catches of
the gripping arrangements still keeping the nippers closed upon the envelope and
blanks, and simultaneously with this movement the sliding bar 19° resumes its
former position ready to repeat its work, and the inking rollers 20 and 20' return
over the type or die 32 and make room for the type bed 32 to rise which is now
caused to do so by the upright bar or shaft 2 pushing it up from below, and
simultaneously with this movement the three cross bars 24, 24 and 241 recede
carrying with them the folded envelope from off the die or form, the gummed and
-printed or embossed blank from off its supports; and the gummed blank from off
the gummer 22, and hold them immediately over the receiving box, the folding
table, and type bed respectively. The three said cross bars also carrying the ends
of the catches 37 of the three gripping arrangements over and above the plates on
the spindles 9° 94, and 9, the guides 32 and 32' at this time being. just below, and
therefore out of the way of the gummed and printed blank.
The said spindles 9° 9d and 9' are now caused to rise and push upwards the ends
of the catches. 37% of the three gripping arrangements, thus opening the nippers
and releasing the said envelope and blanks, the said envelope falling, upon over
lapping edges 36 and 36" of the receiving box, the gummed and printed or
embossed blank falling between the guides 35 35 35 and 35" on the folding
table 35, and the gummed blank falling between the guides 32 32' 33* and 33° and
upon the supports 33" 33" 33° and 33, the two guides 32 and 32' having risen
with the type bed 32 high enough to guide the said blank, and simultaneously
with these movements the cross bar 231 falls carrying with it the bar or
plunger 23 which presses the envelope down in the receiving box, the plate on the
spindle 11 also receiving a slight push upwards, and the rod 23¹ (to which is
attached the die or form) down upon the gummed and printed or embossed blank,

page_text: The mechanism which moves the table 21 has also now, resumed its former position
ready to repeat its motion. The sliding carriage 22 now returns to its former
position over the gum box 31ª carrying with it the gummer 22 over the
scrapers 31, and the inking rollers 20 and, 20'. having resumed their former
position the roller 20' coming in contact with the ink roller 20 receives: a fresh
supply of ink from it, and simultaneously with these movements the sliding
folding plates: 35, 35. 355 and 35" are caused to move over and upon the edges of
the blank, which projects: past the die or form, and thus folding the said blank
upon the said die or form thereby making the said blank into an envelope, and this
movement by pulling the cords or chains attached to the hinged sides of the
receiving box, opens the same, allowing the two springs 28 and 23 on the bar or
plunger 23 to force the four corners of the envelope into the box. The dipper or
feeder. 26 is caused to rise to the top of its stroke out of the gum in the gum
box; 31ª and thus, give the gummer 225 a fresh supply of gum ready to repeat its
work, and simultaneously with this movement the block 35 (seen best in: Fig 12)
receives its upward pressure, and the plate on the top of the spindle 11 at this time
receiving its second push upwards and the type bed 32 having come in contact
with the underside of the cross bar 33 it is moved upwards carrying with it the
gummed blank (to be printed or embossed) towards the block 34 the gripping end
of the blank not being allowed to pass above the nippers, by the projection on the
bracket 37° of the gripping arrangement which is attached to the cross bar 241 The
upright bar or shaft 2 having now got to the top of its stroke, the gummed blank
has been pressed upwards against the block 34 by the type or die 32ª, and the
cross bar 33 whereby it has been printed or embossed. The aforesaid motions
having thus at one and the same time gummed on the seal flap and laid out to dry,
gummed on the folding parts printed or embossed, and folded an envelope blank
and packed an envelope in a box. An envelope or bag is thus turned out complete
at each up and down motion of, the upright bars or shafts 2° and 2º.
And when the machine has made twenty five complete operations as previously
described, it is caused to stop by the pin 3' dropping through the notch in the
flanged wheel 13ª, the weight 3 pulling the lever 3 down with it, and thereby
throwing the two cog wheels 2d and 3 out of gear, the receiving box is now
emptied in the manner previously described, and the travelling board 30 is removed
and placed upon a rack or shelf for the blanks to dry, and another board put in its
place in the machine, and the two tables 17ª and 21ª are also replenished with
blanks and the machine is started again.
Having thus fully described the nature of my said Invention, and shown by
Drawings in what manner the same is to be or may be performed or carried into
practical effect, I would observe in conclusion, that I do not confine or restrict
myself to the precise details or arrangement which I have had occasion to describe
