PROVISIONAL SPECIFICATION.
An Improved Machine for Making and Folding Fly-papers.
We. FREDERICK TUNBRIDGE and JOSEPH NEWTON WRIGHT, of 84 Broad Street,
Reading, Fly-paper Manufacturers, do hereby declare the nature of this in vention to
be as follows:-
This our invention relates to an improved machine for making and folding fly-
papers, but which machine is more especially applicable to the manufacture of that
class of fly-papers set forth in my specification No. 10767, and bearing date the
3rd of July 1889, in which is described a fly-paper as consisting of a piece of non-porous
paper or material having upon one surface a sticky substance but which does not
extend to the edges of the paper, thereby leaving a margin which is folded over to
retain the sticky substance.
It has hitherto been necessary in the inanufacture of these fly-papers to spread the
sticky substance, and to fold the papers by hand, and this, being a tedious and expensive
operation, our machine hereinafter described has been designed to accomplish the two
operations in a neat, simple and expeditious manner.
The mechanism is contained between two side-frames which are suitably braced
together by stay-bars. At one end of this frame-work is secured a water-jacketed
receptacle containing the sticky substance which is melted by a gas jet situated beneath
the receptacle. A suitable roller is adapted to be revolved in the sticky substance.
Above this roller and adapted to come into contact therewith is a smaller roller—herein-
after called the spreading-roller, and above this and in contact with this roller is a
still smaller roller, both of which are suitably mounted in depending portions of two
reciprocating arms.
The ends of the spindle carrying the spreading roller and projecting through the
arms travel over suitable tumbler arms, and the other ends of these arms run in
suitable guides formed on the side frames, and receive their motion from a crank upon
one end of a transverse driving-shaft carrying belt-pulleys. A table is fitted between
the side-frames and is supported upon two vertical rods secured in guides, and having
their lower ends pivotally secured to a horizontal bar, pivoted midway its length to
the framework, and carrying at its projecting end a weight, which keeps the table
elevated. One of the vertical supporting rods is formed with a rack which at the
proper moment is engaged by a toothed cam upon the driving shaft which operation
depresses the table at the proper time against the action of the weight aforesaid.
At the opposite end of the framework to that containing the spreading mechmism
is the folding device, which consists of two fixed metal or other tables arranged between
the side-frames with a slit or space between them. Immediately beneath this slit are
journalled in the framework a set of rollers, and beneath these are two vertical metal
plates arranged face to face with a space between them. One of these plates has its
edges gradually, or as it were, spirally bent over the edges of the other plate. These
plates have spaces cut through them, in which two rollers rotate in contact, and
beneath the plates are a third set of rollers. All of these rollers are rotated by gear
wheels and a small belt-pulley deriving its motion by means of a belt from a pulley
upon the driving shaft.
The operation of the machine is as follows:-The sticky substance is melted by
means of the gas jet, and a supply of paper cut to the required size and shape is placed
upon the depressible table. When the driving shaft is rotated, the reciprocating arms
carry forward the spreading roller from off the roller in the sticky substance, and
running beneath the tumbler-cams. spread the substance upon the upper sheet of
paper, the roller above the spreading roller serving to take off the excessive substance.
Upon the return stroke, the table is depressed, and the ends of the spindle of the

page_text: spreading roller running over the tumbler cams, the spreading roller clears the paper.
During this return stroke the attendant removes the paper which is spread on to the
fixed folding table. On the next forward stroke of the arms, they come into contact
with a small cam on each side-frame which cause two arms to project outwards and
coming into contact with the middle of the paper, force it with its two ends upwards
through the slit between the tables. The paper is now caught by the revolving
rollers, carried between the vertical plates which, by the formation of their edges
fold over the edges of the paper. The folded edges are now creased by the
lowest or third set of rollers, which either carry the paper into a receptacle or allow
it to fall upon the floor.

COMPLETE SPECIFICATION.
An Improved Machine for Making and Folding Fly-papers.
We, FREDERICK TUNBRIDGE and JOSEPH NEWTON WRIGHT, both of 84 Broad
Street, Reading, Fly-paper Manufacturers, 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 :-
This our invention relates to an improved machine for making and folding fly-
papers, but which machine is more especially applicable to the manufacture of that
class of fly-paper set forth in our specification No. 10,767 and bearing date the
3rd of July 1889, in which is described a fly-paper consisting of a piece of non-porous
paper or material having upon one surface a sticky substance, but which does not
extend to the edges of the paper, thereby leaving a margin which is folded over to
retain the sticky substance.
It has hitherto been necessary in the manufacture of these fly-papers to spread the
sticky substance and to fold the papers by hand, and this, being a tedious and
expensive operation, our machine hereinafter described has been designed to accom-
plish the two operations in a neat, simple and expeditious manner hereinafter set
forth.
Our invention may be described as follows, reference being had to the accompanying
drawings and to the figures and letters of reference marked thereon, like letters
indicating similar parts throughout.
Figure 1 is a side elevation of our improved fly-paper machine.
Figure 2 is a side elevation thereof with one of the side frames removed.
Figure 3 is a plan thereof.
Figure 4 is so much of an end view thereof as will serve to show the folding
mechanism in detail.
Figure 5 shows a fly-paper folded by our machine.
The mechanism is principally contained between two side frames A, which are
braced together by stay-bars B. At one end of the framework is suitably secured a
water-jacketed receptacle C containing the sticky substance D which is heated and
melted by any suitable gas jet. E. A roller F is journalled in the side-frames A and
is adapted to be revolved in the sticky substance,-the-motion being transmitted
thereto by a band and the pulley G mounted upon the main driving shaft H. A
frame hereinafter called the roller-frame-consists of two vertical supports I and a
cross piece J and carries two rollers K and L the former being hereinafter called the
distributing roller. The distributing roller K takes the sticky substance from off the
roller F, and the roller L takes the excess of the sticky substance from off the dis-
tributing roller K. The roller-frame is supported by small rollers M-mounted upon
pins projecting from the inner sides of the vertical supports 1-and is guided in its

page_text: movement by suitable guide-rods N carrying at their extremities rollers O adapted to
travel between guides P, preferably cast integral with the side frames A. The guide
rollers M are supported by cans or guides Q also preferably cast integral with the
side-frames A. Two cams O¹ P¹ are shown pivoted to the inside of each side frame,
and have an intervening piece of metal or guide Q' between them. The cam O' is
kept in horizontal position by a weight R¹ (Fig. 1) suspended upon a rod S'. A
crank-arm N upon the shaft H, and a pitman O' communicate a reciprocating
movement to the extended portion P' of one of the guide rods N and the roller frame.
A depressible table R is supported between the side-fraines preferably by rods S one
or both of which run in a guide or guides T-only one of which is shown-and
which consists of a cross-bar having an elongated boss through which the rod S
passes. The rods S are connected by a piece of metal U to which is pivoted one end
of a connecting link V, the other end of which is pivotally connected to one end of a
lever W mounted upon one of the tie-rods B, and carrying at its other end a
weight X. This weight and lever serves to keep the table elevated when in its
normal position. The table is depressed at the proper time against the action of the
weight by means of a tooth-cam Y mounted upon the shaft H, and which engages
with a rack Z upon one of the supporting rods S. Upon the outer sides of the side-
frames are secured two guides a in which travel two depending arms & secured in any
suitable way to the guide-rods N. Fixed tables c, d, extend across the side-frames A
as shown and have a space e between them.
The folding mechanism consists principally of the sets of rollers f. 9. and h, and
the folding plates i and j. The rollers are journailed in brasses or bearings & capable
of longitudinal movement in the slots and of adjustment by the screws n. Springs m
coiled around the screws n serve to keep the rollers in contact, and allow of a slight
parting of the rollers as the paper passes between them. The rollers k meet through
apertures or openings o in the plates i and j. The plates i and jare secured to the
side-frames A in any suitable way-the plate having tapered edges and the plate j
having its edges folded over the plate with a space between them as shown. The
A slot / is
rollers are revolved by gear-wheels p, the pulleys 7, 8, and the band r.
made in each side-fraine A in which is fitted pieces of metal u formed with a rack
and preferably provided with projecting side pieces on one side, and a loop on
the other side. Tooth-cams z pivoted to each side frame and engaging with the
rack v servo to depross the pieces of metal u against the tension of the springs y at
the proper moment. The lower ends of the slots are bevelled as shown, (Fig. 4)
which serves to cause the pieces of metal u to extend outwards as shown by broken
lines.
A fast and loose pulley ¹¹ are mounted at one end of the driving shaft, by means
of which motion is transmitted to the machine by a band from the driving pulley of a
shafting or motor.
In the drawings, the full lines show the various parts in their normal position, and
the broken lines show them in the position they assume when a fly paper has just
been spread with the sticky substance.
When the sticky substance is melted by the gas jet, a supply of paper cut to the
required size and shape is placed upon the depressible table. When the driving-
shaft H is rotated, the guide rods carry forward the roiler frame and spreading
roller K from off the roller F, and the small roller M runs along the cam-guides Q
and under the pawl P, the topmost paper being spread upon the table R. Upon the
return stroke the table R is depressed and the roller M runs over the pawl or cam P
the guides Q' and pawl or cam O¹ back into its normal position, thus clearing the
paper sheets upon the table R. During the return stroke the attendant removes the
paper which is spread on to the fixed tables c, d, the paper being indicated by
the letter a². On the next forward stroke of the guide-rods N the guide rollers Ŏ
come into contact with the tooth-cams which cause the two arms u to be depressed
and projected outwards from the side frames. These arms force the paper through
the space e and carry it between the rollers f which in turn convey it between the
plates and j and the rollers and the latter creasing the edges which are

page_text: folded over by the plates i and j. The paper spread and folded as shown in
Figure 5 is now deposited upon the floor or into a suitable receptacle placed to
receive it.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
The herein described machine for spreading and folding fly-papers, the said machine
consisting of the various parts thereof all arranged in combination substantially as
and for the purposes hereinbefore set forth and illustrated in the drawings hereunto
annexed.
