I, JAMES GATHERCOLE, of No. 4, Cranmer Terrace, Cranmer Road, Brixton,
County of Surrey, do hereby declare the nature of the said Invention for
"IMPROVED MACHINERY FOR MAKING ENVELOPES AND PAPER AND OTHER BAGS,"
to be as follows:-
This Invention is a new description of machine for the purpose of creaseing,
stamping, gumming, and folding blank forms into envelopes and bags, and
for collecting and packing them away being folded.
All machines heretofore made for this purpose are, in fact, a combination
of several machines in one, each part of the process of making an envelope,
requiring a seperate machine, with its properly timed cams, levers, &c., one such
is necessary for the feeding, one for stamping, one for gumming, one for
folding, and one for discharging the envelope when folded, altogether forming
a very complicated machine.
In my machine I do not require these seperate movements, the creasing,
gumming, and stamping being performed by the simple rotation of rollers,
as will appear by the following description:-This machine is small and
strong, and cannot easily be put out of working order, it may be worked at
great speed, and it makes no waste. Two iron sides of the machine are
placed at a proper distance apart, and tied together by three strong rods

page_text: and securely bolted down to a bed plate, through these sides, holes are made,
in which the ends of rollers revolve.
The novelty of my machine consists chiefly in the application of rollers
instead of the old plan for making envelopes and bags.
The accompanying Drawing shows a side view of the machine, the two
rollers below represent them as they appear from a front view.
Figures 1, 2, and 3 represent sockets through which ends of the tie rods pass;
Figures 4 and 5 represent sockets in which the ends of rollers 6 and 7 revolve;
8 and 9 show sockets for rollers over which an endless band or apron revolves
and carries the envelope or bag forward; Figures 10 and 11 represent
sockets for rollers that assist in forwarding the envelope or bag and at the
same time imparting any required amount of pressure to them; Figure 12
shows where the gumming roller works; Figure 13 represents, a pin or stud
on which a timed cam lever oseillates for bringing forward and returning to its
place the feed table 14, also the packing plate 15. On roller 6 is fixed in
one or more pieces a sharp or knife edge creaser 16, just the size of the
envelope when finished, projecting a little from the surface of the roller;
17 and 18 represent small projecting strips of brass or other material for
receiving the gum and printing it on to the envelope at the proper place.
The part of a circle 19, represents (a part only) of the counterpart of the seal
stamp. On roller 7 the part circle 20 shows the position of the seal stamp,
21 represents an elastic band about a tinch thick, be ded into, and flush with
the surface of the roller, rollers 6 and 7 are connected at a, a, by cog'd wheels,
and rollers 7 and 8 are connected by a band, the other rollers may work by
contact, the machine is driven by a pulley on roller 7 at b.
Motion being given to the machine the gumming roller at 12 communicates
gum to the printing strips 17 and 18, the oscilating lever 13 brings in table 14,
and the point of the envelope on it (red) c, will be fed in between rollers
{and just in time to receive the creasing impression at the proper place
from the creasing knife 16, which presses the paper on to and slightly into
the elastic covering on roller 7, which produces a beautiful uniform crease,
the envelope also receives the gum from 17 and 18 and the stamp from
.19 and 20; the gripe of the revolving rollers carries the envelope forward to
.the endless apron d, and in its progress it meets a stop roller, which folds
over the first flap, as seen at 2, where also will appear the end flaps (red)
standing up, these flaps will come into contact with stops and be folded over
before the envelope reaches the pressing rollers 9 and 10, between which it
passes, having three flaps folded; the envelope at then is raised by a spring
or other means and brought between the rollers 9 and 11, whereby the last

page_text: flap is folded and the final pressure given; it then drops finished in front of
the plate 15, which pushes it forward to and leaves the envelope at g, the
plate then returns for the next. It will be seen that by this small powerfull
yet simple machine envelopes and bags may be made at great speed and
economy.
