By my present Invention which is an addition and an Improvement to that for
which Provisional Protection was granted to me on the ninth day of October 1882
and numbered 4793, especially for the purposes of Embossing Crests, Monograins
or other similar requirements as may be needed, which may be effected simul-
taneously either plain or in colour or colours as may be desired in conjunction
with the Folding and Gumming operations as herein referred to and about to be
described as follows:-

page_text: I provide in the first instance a suitable frame or standard of cast iron or other
material whereon I fix or secure a base or table having two or more vertical
standards attached so as to enable two horizontal shafts being supported and working
therein in suitable bearings on to which the driving gear, wheels and pinions also
the fly wheel, riggers, cams and other necessary attachments are secured for
actuating the mechanism as hereinafter described, and may be driven by means of
either hand, steam or any other suitable power.
-
On the lower horizontal shaft working in the vertical standards I fix or provide
at one end the rigger pulley or pullies also the fly or balance wheel keyed thereto,
I also provide a clutch box or other suitable mechanical means for throwing the
same in and out of gear.. On the said horizontal shaft and keyed thereon a Spur,
bevil or other wheel (or wheels) is fixed working into another suitable or corre-
sponding wheel (or wheels) secured on the upper horizontal shaft and so arranged
as to cause an increase of power thereto, and at the further end of the said upper
horizontal shaft I provide and affix a series of Cams or Eccentrics secured thereon
working in concert with three vertical plungers or rods and connected thereto
working in guides and so disposed as to produce the required alternate or inter-
mittent motion for the several purposes of stamping, creasing, folding, and
likewise gumming, as hereinafter described. The object of the centre plunger
or rod being so disposed is to produce a double stroke at each revolution of the
upper horizontal shaft, At the lower portion, of this plunger or rod, working
within a suitable guide. I attach a die or creaser for the purpose of giving the
necessary impress to the paper blank provided below which receives and is forced
by its downward pressure into a box or suitable receptacle properly disposed for
he purpose intended, and I likewise connect, in a similar manner a vertical spindle,
or connection to which is attached a rod or lever so arranged as to produce suitable
motion and to act upon a door or similar arrangement provided under the bed or
table already referred to, and fitted with hinges or joints so as to permit the
envelope or similar article when folded and completed to be automatically
discharged. The inner vertical plunger or stamper being for the purpose of
stamping crests, dies, or monograms is actuated in a similar manner by means
of cams, or eccentrics worked from the upper horizontal shaft, a slide suitably
formed and arranged is also caused to travel, or is actuated alternately backwards
and forwards in a horizontal direction with each revolution of the machine, the
said slide being worked in the manner described by means of a cam and crank-
lever worked from the upper shaft and so arranged as to cause or give the slide it's
required back motion, a spring or springs or other suitable arrangement being
employed to cause or give it the desired return or forward action, Upon the
travelling slide just referred to, working in suitable guides or grooves and attached
to and working the same, I cause to be affixed an inking table passing under two
or more inking rollers suitably disposed, and causing the die to receive the ink or
colouring matter ready for being acted upon by the vertical inner plunger referred
to. I propose to so arrange the inking or colour rollers as to be fixed or enclosed
in a suitable frame, and dropped into a slot or slots, and capable of being readily
removed with the rollers for the purpose of being cleansed when needed. I like-
wise provide a feeder for distributing the colouring matter to the inking or colour
rollers.
From the central guide are attached two guide bearings, to which are connected
jointed levers which on the downward stroke of the plunger are enclosed therein
during the creasing process, thereby causing the sides of the envelope to be raised
nearly in, or about a vertical position the ends of which are taken in and com-
pressed in the Second, or return action of the said levers, and from the aforesaid
central guide are also attached two actuating springs working with and at the
same time with the levers just described for the purpose of enclosing the two sides
whereby the envelope to this extent is completed. The outer plunger actuated
by means of cams, or eccentrics as before described is for the process of

page_text: "gumming," a suitable arrangement in connection being provided, dipping from
time to time into a receptacle provided, containing the necessary adhesive substance
for this purpose, and in the alternate action previous to the creasing, and final
developing of the process, and thus immediately producing in combination with
the mechanism referred to the objects sought to be obtained.

For the better explanation of my said invention I refer to the accompanying
drawings in which the like letters refer to the like parts throughout the several
views. Figure 1. is a front elevation of the machine with the table, table frame,
creaser box, and gum reservoirs in section. Figure 2 is a side elevation of the
machine with the lower part of the table frame removed. Figure 3 is a sectional
plan taken just above the table, through the feet of the standard, and showa
the plan of the cames, inking apparatus, creasing box, and arms of gummer.
Figure 4 is a vertical section of the creaser-box with the creaser folding levers,
and springs shown above it, and in their relative position with regard to the
creaser-box when the latter is being fed, with the envelope blank. Figure 5 is a
plan of the creaser and folding levers, and springs. Figure 6 shows a vertical
section of the creaser-box, and creaser with the latter in it's lowest position in the
box, that position which it occupies when the envelope blank is being creased.
Figure 7 is a front view of the arm which presses the edges of the envelope against
the arms of the gummer. Figure 8 is a plan of the above. Figure 9 is an
elevation of the arms of the gummer, and shows the manner in which they are
connected. Figure 10 is a plan of the same.
By my invention I provide in the first instance a suitable frame a of cast iron
or other material whereon 1 fix or secure a base or table 6 having two or more
vertical standards c, c attached so as to enable two horizontal shafts d d to be
supported, and work therein in suitable bearings c, c', c, c' to which the driving
gear, wheel e and pinion e', also the fly-wheel f, rigger f¹, cams g, g², g³ g³, gʻ, and

page_text: other necessary attachments are secured for actuating the mechanism as nerem
after described, and may be driven by means of hand, steam, or any other suitable
power. On the lower horizontal shaft working in the vertical standards c, c I fix
or provide at one end the rigger, pulley, or pullies, f¹, also the fly or balance
wheelf. I also provide a clutch-box f, or other suitable mechanical means for
throwing the same in and out of gear; On the said horizontal shaft d¹, and keyed
thereon a spur, or other suitable wheel e' (or wheels) is fixed working into another
suitable or corresponding wheel (or wheels) secured on the upper horizontal
shaft d, and so arranged as to cause an increase of power thereto, and on the
said horizontal shaft d I provide and affix a series of cams, or eccentrics
secured thereon g, g¹, g², g³g, working in concert with vertical plungers, or
rods h, h¹, h, n¹, k, and connected thereto, and three of which h, h1, h2 work in a
guide frame c³, and the others in the guides c³, c, and all so disposed as to produce
the required alternate or intermittent motion for the several purposes of stamping,
creasing, folding, and likewise gumming, and embossing as hereinafter described.
the object of the centre plunger or rod h¹ being so disposed is to produce a double
stroke at each revolution of the upper horizontal shaft d. At the lower portion
of this plunger or rod working within the aforesaid guide frame I attach a die or
creaser for the purpose of giving the necessary impress to the paper blank
provided below, which receives, and is forced by it's downward pressure into a
box or suitable receptacle properly disposed for the purpose intended, and I
likewise connect in a similar manner a vertical spindle k, or connection, to which
is attached a rod or lever k¹ so arranged as to. produce suitable motion, and to act
upon a door, or similar arrangement provided under the bed or table already
referred to, and fitted with hinges, or joints so as to permit the envelopes or similar
articles when folded and completed to be automatically discharged. The inner
vertical plunger or stamper h being for the purpose of stamping crests, dies, or
monograms is actuated in a similar manner by means of the cam g³, or eccentric,
worked from the upper horizontal shaft d, a slide suitably formed, and arranged
is also caused to travel or is actuated alternately backwards and forwards in a
horizontal direction, with each revolution of the machine, the said slide being
worked in, the manner described by means of a stud in the spur-wheel e, and
crank-lever n', worked from the upper shaft d, and so arranged as to cause or give
the slide it's required back motion, a spring , or springs or other suitable arrange.
ment being employed to cause or give it the desired return or forward action.
Upon the travelling slide 7 just referred to, working in suitable guides or grooves,
and attached to, and working the same, I cause to be affixed an inking table 15
passing under two or more inking rollers 16, 16 suitably disposed, and causing the
die ', to receive the ink or coloring matter ready for being acted upon by the inner
vertical plunger h³, referred to. I propose, to so arrange the inking or color
rollers .. that they shall be fixed or enclosed in a suitable frame 18, and dropped
into a slot or slots 1°, 18, 19, 1º. and be capable of being readily removed for the
purpose of being cleansed when needed. I likewise provide a feeder 10 for distri-
buting the coloring matter to the inking or color rollers 1. 1. From the guide
frame care attached two guide bearings m to which are connected jointed levers m¹
which on the downward stroke of the plunger or rod i are enclosed therein during
the creasing process thereby causing the sides of the envelope to be raised nearly
in or about a vertical position, the ends of the envelope being taken in, and com-
pressed in the second or return action of the said levers m¹, and from the aforesaid
guide-frame c', are also attached two actuating springs m³ working with, and at
the same time with the levers just described for the purpose of enclosing the two
sides, thereby the envelope to this extent is completed. The outer plunger h to
the lower end of which is attached the arm o which presses the envelope blank
against the gummer n, actuated by means of the cam or eccentric g as hereinbefore
described in conjunction with the gummers n. n and vertical rods n', n', actuated
by the cam g³, accomplishes the gumming process, the adhesive substance being
.stored in the reservoirs p, p, which are respectively provided with an overflow
:

page_text: pipe p¹, to prevent the said reservoirs being overcharged with gum, the surplus
gum passing down the overflow pipes p, p, into the cans p', p². To provide in
some cases where it may be desired for a further rapidity of feeding the envelope
blanks, in a more simple manner than hitherto obtained direct by hand or other-
wise, I propose to provide an incline whereby they may be suitably led, or guided
into the folding-box, and in some cases I would also propose to provide two or
more rollers worked by means of a band or pullies from the upper horizontal
shaft d and so arranged on the bed or table as to be led or guided as aforesaid
ready to be operated upon.
Having now fully explained the nature of my said invention and the means by
which it is to be carried into practice, what I claim as secured to me by the
hereinbefore in part recited Letters Patent is substantially as stated in the fore-
going specification and illustrated in the accompanying drawings. In Witness
whereof I the said Edwin Sturge have hereunto set my hand and seal this
