A New and Improved Attachment to Folding and like Machines.
I, WILLIAM BRIDGEWATER, of 30, St. Peter's Lane, Leicester, in the County
of Leicester, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a means of putting a strip of adhesive material such
as paste or gum along a sheet of paper during the process of folding pamphlets
or the like whereby the leaves are secured firmly together without the necessity
of sewing with thread or wire. For this purpose I use a receptacle for holding
the adhesive with a small grooved wheel at the bottom and another at the top
the two being connected by an endless band or cord passing through the adhesive
thereby carrying a portion of such adhesive on its surface the quantity being
regulated by a suitable cover through which the band passes in coming over
the lower wheel. A driving wheel is fixed on the axle of the top wheel and is
driven by belt or cord over suitable pulleys from a pulley on a suitable shaft
of the folding or like machine. The holder of the adhesive is attached to the
end of a lever arm and is raised and lowered at the proper time by levers and
a cam on the shaft from which the endless band receives its motion.

A New and Improved Attachment to Folding and like Machines.
I, WILLIAM BRIDGEWATER, of 30, St. Peter's Lane, Leicester, Engineer, 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 follow-
ing statement:-
This invention relates to a new or improved attachment to folding and like
machines by means of which a strip or line of adhesive substance such as paste
or gum may be applied along a sheet of paper during the process of folding
pamphlets or the like, the leaves thereby being secured firmly together without
the necessity of sewing with thread or wire.
The
For this purpose I use a receptacle for holding the adhesive substance with a
small grooved wheel at the bottom and another wheel at the top the two being
connected by an endless band or cord passing through the adhesive substance
thereby carrying a portion of such adhesive substance on its surface.
quantity or supply of the substance is regulated by a suitable cover through which
the band passes before passing over the lower wheel. A driving wheel is fixed
on the axle or spindle of the top wheel and is driven by a belt or cord passing.

page_text: over suitable puneys from a pulley on any suitable shaft of the folding or like
machine.
The said receptacle or holder of the adhesive substance is attached to the end
of a lever arm and is raised and lowered at the proper time by levers and a cam
on the shaft from which the endless band receives its motion.
The invention will be fully understood by the following further description
reference being made to the accompanying drawing, in which,
Figure 1 is an end elevation and Figure 2 a side elevation of a receptacle or
holder constructed, in accordance with this invention..
Figure 3 is a sectional view showing how the substance passes from the receptacle
into the cover.
Figure 4 is a view illustrating how the receptacle or holder is carried on the
end of a lever and the cams for actuating said lever.
The receptacle or holder A is formed with a slide A¹ to receive therein the
movable cover B, which as seen clearly in Figure 3 is made hollow and with one
side B open so that the adhesive substance can pass through the perferated
plate C soldered on to the receptacle A
The receptacle or holder A it will be readily understood may be made in other
shapes than shown in the drawing the particular shape or conformation being
immaterial so long as provision is made for the holder to be carried on a lever arm
and for variation in any details of construction.
In the form of receptacle or holder shown in the drawing the lever arm D is
received into recesses D¹ D' formed on either side of said receptacle.
The wheel E carried on the spindle E at the bottom of the receptacle or
holder is grooved to receive thereon the cord F which passes through the cover B
the bottom of the latter being shaped and adjusted to adjoin on the periphery of
said wheel.
The wheel G at the top of the receptacle or holder is fixed on the spindle H
and the ends of the latter are supported in two lever arms J J which are pivotted
at K to the lug K¹ formed on the top of the receptacle. The two lever arms J J
pass forward and are joined together at the forward end and have pivotted
thereto at J¹ a slotted link J3 and by means of the thumbscrew L passing through
the said link into the lug A³ in the receptacle or holder the wheel G may be
slightly adjusted and so draw the endless cord F tight.
As the adhesive substance requires some impetus to be given it to cause it to descend
and always keep a supply passing through to the cam Ba worm M is caused to rotate
slowly in the said substance. The said.worm is carried on a spindle M' which is
pivotted at M2 to the joint nut M³ which holds the spindle N in position.
The said spindle passes upward through the plate J3 formed with the two
lever arms J, J, and has fixed thereon the worm wheel which is rotated by
means of the worm 01 on the spindle H, the latter being driven by a band or
cord passing from a pulley on any suitable shaft of the feeding or like machine
and around the pulley P. Other forms of mechanism or devices for slowly revolv-
ing the worm M may be readily devised.
As it is desirable that the strip or line of adhesive substance should be readily
varied or regulated for any desired purpose, the lever D Figure 4 has a runner Di
which rides upon two edge cams Q. The shape of the said cams Q is identical
but while one cam is formed with slots R R the other cam is drilled to receive
the pins S. S so that one cam may be turned with relation to the other to regulate
the amount of strip or line as before stated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: -
1. The improved attachment to folding and like machines for applying a strip
or line of adhesive substance to pamphlets and the like comprising a receptacle 5
for the adhesive substance, a cover into which the substance passes, an endless

page_text: cord passing over pulleys and means for tightening the cord substantially as
described.
2. The combination with the parts specified in Claim 1 of a worm or equiva-
lent M and means for slowly revolving the said worm as and for the purpose
described.
3. The combination with the parts specified in Claims 1 and 2 of means for
regulating the length of the strip or line substantially as described.
