COMPLETE SPECIFICATION.
Improvements in Machines for Inserting Papers in the Folds of
Textile Fabrics.
We, FRANK RILEY, Engineer, and EDMUND O'CONNOR, Book-keeper, both of the
Elton Iron Works, Bury, in the County of Lancaster, 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 invention relates to machines for inserting papers in the folds of textile fabrics
such as are described in the Specifications to British Letters Patents numbered 858
of 1893, 7187 of 1894, and 24921 of 1895. Such machines are provided with three
tables in line, the two outer ones carrying the sheets of paper which are fed by suitable
mechanism between the folds of the cloth carried by the inner table. The inner table
automatically falls as the folding proceeds and as the folded cloth and inserted papers
accumulate thereon, and the outer tables automatically rise as the piles of paper sheets
upon them are decreased, so that the upper fold of cloth and the highest sheets of
paper are practically always at the same level.
The principal objects of the present invention are to render the construction of such
a machine more simple, and to enable the insertion of the papers and the folding of
the cloth to be performed in a more expeditious and a quieter manner than hitherto.
Means are also provided by which the inner table may be quickly and simply returned
to its highest position when the folded cloth has been removed.
The accompanying drawings to which we will hereinafter refer illustrate in what
manner our improvements may be carried into effect.
Figure 1 represents in sectional elevation one end of the improved machine showing
one form of the new paper feeding device.
A is one of a series of arms which are arranged at suitable distances apart across
the machine and are hinged or pivotted to the transverse rail B in such a manner as
to be capable of vertical movement. Each arm is provided with or is connected to an
indiarubber or other suitably shod foot a and is connected by a chain or the like to
the end of one of a series of arms C extending from or secured to the rocking shaft D.
This rocking shaft is mounted in suitable bearings upon the rail B and this rail has a
reciprocating or to-and-fro motion in the direction of the length of the machine, imparted
to it in any convenient manner. The end of the rocking shaft is provided with
a further extension or armi F the end of which carries a bow! E adapted to engage
with and run along the bar G which has an inclined part and horizontal extensions
therefrom. This bowl may be of such dimensions or be so weighted as to always rest
upon the bar G, its movement down the inclined part lifting the foot or feet a from
the upper sheet of paper, and its movement up the inclined part lowering it or them
into contact again. If desired, however, a separate and distinct counterweight may
be attached to the shaft D to effect the same movements. The bowl E may be covered
with indiarubbber or the like to deaden or altogether suppress the noise of working,
and the junctions of the inclined part of the bar G with the horizontal parts may be
more gradual than those illustrated so as to still further increase the smoothness of
novement.
Secured to the front of the rail B and capable of a limited vertical movement is a
bracket or the like K, a modified form of which is shown more fully in Figure 2.
When the rail B has reached its extreme outward position, that is to the left of the
igure, this bracket, which has travelled backwards along the surface of the paper,
Irops down into a position to engage with the edge of the top sheet of paper upon the
D

page_text: next stroke of the rail. To ensure that the bracket shall not engage with the edges
of more than one sheet at a time, its front edge is recessed or cut away to a depth
sufficient for one sheet but no more, and the bracket is not moved far enough back for
this recessed part to get clear of the pile of papers. A convenient way of mounting
or arranging each of the brackets K is to provide the vertical limb with a slot through
which passes a bolt or screw as illustrated more clearly by Figure 2.
The operation of the feeding devices is as follows:-When the rail is at the
extreme end of its outward stroke the bowl E is at the top of the inclined part of the
bar G or is upon the upper horizontal extension, and the foot or feet a is or are
consequently lowered into contact with the top sheet of paper P. Upon the forward
'movement of the rail B the top sheet is fed forward by the frictional contact of the
feet a until the bowl E commences to descend the inclined part of G. The feet a are
now lifted from the top sheet which however is still fed forward by the brackets K
engaging with its rear edge. The rail continues its stroke, the bowl E running along
the lower horizontal extension of the bar G, until the sheet of paper has been placed
in its proper position in the cloth. The rail then returns, the bowl E is again
lifted by passing up the inclined part of G and the feet a are lowered to feed
another sheet.
Figure 2 is an illustration of a modified form of bracket K in which the foot,
instead of being recessed to the thickness of one sheet of paper, is provided with a pin
or projection adapted to engage with a slot or perforation in the top sheet of paper
and thus feed it forward.
Figure 3 illustrates in plan the devices shown in Figure 1. It also illustrates a new
and improved means for operating the cloth holding blades, one of which is indicated
by L. In this case the connecting rods M which extend along the sides of the
machine are formed to engage with the ends of the blades L which extend through
the machine framing for the purpose. Each blade is pivotted at a convenient point
and is moved in one direction by the spring or indiarubber cord R and in the
other direction by the engagement of its end with the reciprocating connecting
rod M.
In these figures only one of each is represented but it will be understood that four
of the blades Land any convenient number of arms C and A and feet a and brackets K
may be employed.
When
Figures 4, 5, and 6 represent the apparatus for winding up the inner cloth table, in
side elevation, plan, and end elevation respectively. N is the fast pulley and N¹ the
loose pulley of the machine. Attached to the loose pulley is a chain wheel O connected
by a chain with the wheel Q upon the winding shaft S of the centre table T.
the machine is at rest and the belt is transferred to the loose pulley the chain wheel O
is rotated and drives the wheel Q which is freely mounted upon the shaft S.
By putting into gear the clutch s the motion is communicated to the shaft S and the
table is thereby raised to the required height, when the clutch is again released.
The most convenient way of connecting the wheels O and Q together is through the
medium of the countershaft and wheels o, but other arrangements may be employed
and chains may be substituted by other devices.
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 :-
1. In paper inserting machines of the type set forth, the combination with a suitable
reciprocating rail of a rocking shaft to which suitable paper feeding arms are
connected, all constructed, arranged and operated substantially as hereinbefore
described and as illustrated by the accompanying drawings.
2. In paper inserting machines of the type set forth, the combination with a suitable
reciprocating rail or other part, of a vertically moving bracket or of brackets adapted
to engage with the rear edge of the top sheet of paper or with a slot or perforation
formed therein, substantially as hereinbefore described and as illustrated by the
accompanying drawings.

page_text: 3. In paper inserting machines of the type set forth, cloth holding blades the ends
of which project through the machine framing and are adapted to be driven or
operated by the reciprocating side rods of the machine, substantially as hereinbefore
described and as illustrated by the accompanying drawings.
4. In paper inserting machines of the type set forth, the combination with the
winding shaft of the centre table and with the loose pulley of the machine, of suitable
connecting driving devices or mechanism, substantially as and for the purpose
herein before described and as illustrated by the accompanying drawings.
