By my present Invention I provide 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 thereto so as to enable two horizontal shafts being
supported and working therein in suitable bearings to which the driving gear and
wheels and pinions also the fly-wheel, riggers, cams or other necessary attachments
are secured for actuating the mechanism as hereinafter described and may be driven
by means of Steam or 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, to the said rigger or pulley I
also provide a clutch box or other suitable mechanical means for throwing the
same in or out of gear, on the said horizontal shaft and keyed thereon a spur wheel
is fixed working into another suitable wheel secured on the upper horizontal shaft
so arranged as to cause an increase of power thereto, and at the further end of the
same shaft I provide a series of cams or eccentrics fixed thereon having three
vertical plungers or rods connected thereto and so disposed as to produce the
required alternate or intermittent motion for the purposes as hereinafter described,
the object of the centre plunger or rod being to produce a double stroke at each

a box or suitable receptacle suitably disposed for the purposes intended, and I
likewise connect in a similar inanner a vertical spindle or connection to which is
attached a rod or lever so as to produce suitable motion as to act upon a door or
similar arrangement provided under a bed or table already referred to and fitted
with hinges or joints so as to enable the Envelopes to be automatically discharged.
From the central guide is attached two guide bearings to which are connected
jointed levers which on the downward stroke are enclosed in the plunger during
the creasing process, thereby causing the sides of the Envelope to be raised in a
vertical position, the ends of which are taken in and compressed in the second or
return action of the said levers and from the aforesaid central guide aro also.

just described for the purpose of enclosing the two sides thereby completing the
Envelope. The outer plunger actuated by means of Cams or Eccentrics as before
described is for the process of gumming," a suitable adhesive substance being used
in connection therewith for this purpose and in the alternate action previous to the
creasing and final developing of the process and thus immediately producing and
perfecting the objects sought to be obtained by this Invention.

My Invention relates to "improvements in the manufacture of envelopes, and
other similar articles, and in the machinery or apparatus, wherein rotary, or other
suitable motion is employed as an actuating medium for the production of the
same." For the better explanation of my said invention I refer to the
accompanying drawings in which similar letters refer to similar 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 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 shows the plan of the 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 positions with regard to
the creaser box when the latter is being fed with the envelope blank.

Figure 6-Shews a vertical section of the creaser-box, and creaser, with the latter
in its 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 a suitable frame a, of cast iron or other material
whereon I fix or secure a base, or table b, having two or more vertical standards
cc attached thereto, so as to enable two horizontal shafts d, d¹ to be supported,
and worked therein in suitable bearings c¹, c', c³, c², on to which the driving gear,
wheel e, and pinion e¹, also the fly-wheel rigger f¹, cams g, g', g², g³, g, and
other necessary attachments are secured for actuating the mechanism as hereinafter
described, and may be driven by means of hand, steam, or any other suitable
power.
On the lower horizontal shaft d³, 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 wheel f
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 d³, and keyed thereon a
spur or other suitable wheel e is fixed, working into another suitable wheel 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, g³, g, having three vertical plungers, or rods h,
h³, h in working contact thereto, and so disposed, as to produce the required
alternate, or intermittent motion for the several purposes of stamping, creasing,

page_text: folding and gumming as herein described, the object of the centre plunger or rod
being to produce a double stroke at each revolution of the upper horizontal shaft d.
At the lower end of this plunger or rod, and working, within the guide-frame o³, I
attach a die, or creaser i for the purpose of giving the necessary impress to the
paper-blank which is provided below, and which receives and is forced by its
downward pressure into a box jor suitable receptacle properly disposed for the
purpose intended, and I likewise. connect in a similar manner to the upper
horizontal shaft d, a vertical spindle k, or connection to which is attached a rod, or
lever, so arranged as to produce suitable motion, and to act upon a door j, or
similar arrangement provided under a 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. From the aforesaid guide frame of
are attached two guide bearings m, m, to which are connected jointed-levers m', m³,
which on the downward stroke of the plunger or creaser 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
compressed in the return, or second action of the said levers m' m², and from the
aforesaid guide-frame c', are also attached two actuating springs m³, 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 to the lower end of which is attached the arm o, which
presses the envelope-blank against the gummer n, is actuated by means of the
cam, or eccentric g, as before described, in concert with the gummers n, n, and
vertical rods n', n² actuated by the cam accomplishes the gumming process the.
adhesive substance being stored in the reservoirs p, p, which are respectively
provided with an overflow pipe p¹ to prevent the said reservoirs being overcharged
with gum, the surplus guin passing down the overflow pipes p. p into the
cans p², p².
Having now fully explained the nature of my said invention and the means by
which it is to be carried into practice I wish it to be understood that what I
consider as new and therefore claim to be secured to me by the herein before in part
recited Letters Patent is substantially as is herein mentioned and illustrated in the
accompanying drawings. In Witness whereof I the said Edwin Sturge have here-
unto set my hand and seal the ninth day of April in the year of our Lord One
thousand Eight Hundred and Eighty three.
