"IMPROVE-
My improved machine consists of the following parts, namely, a bed plate under
which are bearing brackets carrying a driving shaft provided with fast and loose
pulleys, so as to enable the machine to be driven by steam power, or by a treadle
moved by the foot of the attendant, on the driving shaft are two cams, each of
which operates a slide carrying a bracket provided with a double slotted plate, the
slots actuate a pair of cutter blades, the bracket slide carries a stud capable of
adjustment so as to regulate the traverse given it by the cam. Each pair of cutter
blades is carried by, and is capable of adjustment vertically, in an overhanging
bracket carrying a spring to keep the cutters down, each bracket being moved in
V slides by a series of links, and a rocking lever operated by a cam on the driving
shaft
There is a second double ended overhanging bracket provided with a slide in
the centre, in which a pressing plate is capable of adjustment, by means of a set
screw and lock nut, but the plate can be raised or lowered by a lever, and be held
where required by a wing nut and screw. At the front and back of the pressing
plate upon separate axles, double ended slotted levers rock, each lever carries a pin
at its upper end to which one end of a coiled spring is secured, the other end of the
spring being secured to a stud in the pressing plate, the lower end of each slotted
lever is provided with an adjustable picker point, these points have a rocking
motion and also a rising and falling motion communicated to them, the rocking
motions being effected by slotted rocking levers carried by the cutter blade
brackets, the rising and falling motion by a lever rocking on an axle carried by the
double ended overhanging bracket before named, one end of the rocking lever
being secured to the upper end of a connecting link, having its lower end attached
to a rocking lever operated by a cam on the driving shaft. The fabric to be
operated upon is wound on a weighted roller at the back of the machine, beneath
the bed plate, from this roller the fabric is passed under and over adjustable
guiding rods, and beneath adjustable weighting plates, then under the pressing
plate before named to and between two india-rubber covered rollers geared together
and revolving in bearings at the front of the machine. Both at the front and back
of the pressing plate is an axle carrying a series of toothed or pointed rollers, these
rollers prevent the fabric from moving to the right or left while passing from the
weighted roller to the india-rubber covered rollers. The fabric passing between
the india-rubber covered rollers has an intermittent movement communicated to it
by a cam on the driving shaft, operating a rocking lever the axle of which carries
a slotted lever in which one end of a connecting link is capable of adjustment, this
link at its front end is hinged to a pin, sliding in a sleeve or link, carried by the
boss of a driving roller, keyed fast on the axle of one of the covered rollers, the
sliding pin carries a truck, which takes into a slotted are capable of adjustment
by means of a hand lever, the sleeve carries two driving clutches, which operate the
driving roller, by which means the greater or less partial revolution of the driving
rollers is effected.
The operation of the machine is as follows:-The lace, muslin, or other fabric
having floating threads upon its surface which are required to be clipped off is held
down by the presser plate, which has a portion cut away at the centre of its length,
in which the floating thread is left free to allow of the picker points to get under
them, the points are then slightly raised to allow of one blade of each pair of
cutters, to pass under the thread, the blades then cut off such thread at each end,
and the picker point levers rise still higher so as to place the thread so cut off, into

page_text: .
a split trough from which they slide or fall into a convenient receptacle, and the
movements are repeated
As the fabric passes from the rubber covered rollers it is wound upon a roller at
the front of the machine, which is revolved by an elastic hand passed round it, and
the driving shaft
And in order that my said invention may be fully understood, I shall now proceed
more particularly to describe the same, and for that purpose shall refer to the
several Figures on the annexed sheets of drawings.
Figure 3 an underside view shewing the driving shaft carrying the cams for
operating the several' parts and.
Figures 4 to 7 inclusive are separate views of portions of the apparatus, severally
referred to hereafter.
The corresponding parts in each Figure are indicated by the same letters where
necessary
My improved machine consists of the following parts, see Figures 1, 2 and 3. A
bed plate A under which are bearing brackets A', A³, carrying a driving shaft A³
which may be provided with a fast and loose pulley or a grooved pulley B, round
which a belt or cord may be passed from a main shaft to enable the machine to be
driven by power, or it may be operated by a treadle moved by the foot of the
attendant, or otherwise as may be convenient. On the said driving shaft A³ are
two cams C, C, each of which operates a link C¹, the back end of which carries a
stud sliding in a slot in the bed plate. In the same slot is a second stud capable
of adjustment, by means of a wing nut or its equivalent, so as to regulate the
traverse given to the link C¹ by the cam C. Each link is held to its cam by a
spring attached to it and to the underside of the bed plate, the front end of the
link has an axle pin passed through it and screwed into the underside of a slide
working in a double V bearing on the bed plate, each slide carrying a bracket C³,
provided on the top with a double slotted plate C³ in which studs secured in the
outer ends of cutter blades C slide, the inner or cutting ends of the blades vary
in length the blade operated by the straight slot, is pointed and shorter than the
blade operated by the cranked slot, this blade is broader at the end than the other
and is also turned up at its point to prevent it getting under the floating threads
required to be clipped off. Each pair of cutter blades is carried by a bolt capable
of adjustment vertically by a nut at its upper end in an overhanging bracket D,
the lower end of the bolt is encircled by a spring which keeps the cutters down,
each overhanging bracket is moved in V slides on the bed plate by a series of
links D' on the underside of the bed plate, and a rocking lever D' operated by a
cam Ds on the driving shaft.
Secured to the top of the bed plate is a double ended overhanging bracket E
provided with a slide E2, in the centre, in which a pressing plate E' is capable of
adjustment, by means of a set screw and lock nut e at the top, and held when
adjusted by a screw e³ at the front. At the front and back of the said pressing
plate E upon separate axles, double ended slotted levers F rock, each lever carries
a pin fat its upper end, to which one end of a coiled spring e³ is secured, the other
end of the said spring, being secured to a stud in the pressing plate, the lower end
of each lever F is provided with a picker point F¹, these levers and points have a
rocking motion and also a rising and falling motion communicated to them, the
rocking motions being effected by slotted rocking levers G hinged at one end to
the cutter blade brackets D, the slotted ends of the levers being provided with an
adjustable set screw g and in the slots the pins fat the upper ends of the levers F
slide, and as the brackets D slide outwards the set screws g strike the pins and place
each lever and picker point in the position shewn at Figure 4 which is separate view of

page_text: the presser plate E¹. As the brackets D move inwards, the springs 6° restore Tue
levers F, and picker points F¹ to the position shewn at Figure 1. the rising and
falling movements of the said levers and points being effected as follows:-The
forked end of a lever H rocking on a fulcrum pin in the double ended overhanging
bracket E lies under the pins fin the levers F and the outer end of the lever H
receives the upper end of a connecting link H' having its lower end attached to a
lever H' rocking on an axle in a bracket secured to the underside of the bed plate,
and carrying a " truck or stud with an anti-friction sleeve thereon, at its opposite
end operated by a cam H³ on the driving shaft
"
A side view of this cam is shewn at Figure 5. The groove of the cam D³ is
shewn laid out at Figure 6.
The fabric to be operated upon may be either wound upon a weighted roller at
the back of the machine, or it may lie loose in any convenient receptacle, from
whence it is passed between guide bits J adjustable in a slot in the bed plate, over,
and under two fixed rods J', then over the two outer, under the central rod, of
three rods K which are supported by a plate K' which is capable of adjustment to
or from the pressing plate E¹ by means of the screws k shewn in plan at Figure 2.
The said three rods carry two guide plates K2 capable of adjustment to or from
each other by sliding on the rod, and provided with set screws k', which clamp
them to the centre rod, the front rod has a weighting plate K³ hinged to it, under
which the fabric is passed then under the pressing plate E¹ before named. Both at
the front and back of this plate is a toothed or pointed roller, the axle of the back
roller K revolves in bearings at the front of the plate K¹ and the front roller K
in bearings at the back of a front guide plate K. The said rollers K*, K³ prevent
the fabric from moving to the right or left, while passing from them to and between
the front rollers L, L', which give an adjustable intermittent movement to the said
fabric, by a cam M on the driving shaft. This cam has a double V groove
in which an axle is capable of adjustment, to or from the centre, this axle carries
one end of a connecting link M¹ having its other end secured on an axle pin m the
inner end of which carries a piece sliding in the slot of a lever M³ mounted
loosely upon the boss of a driving roller M³, having two clutches m³ of the usual
construction for this class of motion the roller M³ being keyed fast on the axle of
the roller L'. The outer end of the axle pin m takes into the lower end of a link n
having its upper end carried by a stud in the back end of a hand lever N. rocking
on a stud N in a bracket n³ secured to the underside of the bed plate A by
which means the greater or less partial revolution of the driving rollers L, L' is
effected. The lever N is held in the position in which it is placed by friction thus
ensuring each intermittent movement of the rollers L and L' being of equal length
until a readjustment is made. A sectional end view of the presser plate E¹, guide
rods and plate K¹, guide plate K* pointed rollers K* K* and covered rollers L, L' is
shewn at Figure 7
The operation of the machine is as follows:-
The lace muslin or other fabric having "floating threads" upon its surface which
are required to be clipped off, is held down by the presser plate E' which has a
portion cut away at the centre of its length in which the floating thread is left by
the depression of the main body of the fabric, to allow the picker points F' to get
under them, the points are then slightly raised to allow one blade of each pair of
cutters, to pass under the said thread. The said cutters then cut off such thread
at each end, and the picker point levers rise still higher so as to pass the thread so.
cut off into and through a slot o and eventually into a split trough O shewn in side
view of Figure 7, this being effected by the pressure of succeeding threads being
raised by the toothed parts of the pickers. These movements are repeated as the
fabric proceeds, and it eventually passes from the rollers L, L¹ to a suitable
receptacle.
Although I have described two pickers as being used, it will be understood that
one or two or any greater number, may be used as desired, they being operated
by means substantially like those described. It will also be evident that the said

page_text: .
picker or pickers may be operated to separate the floats in other than an upward
direction
I do not limit myself to the means shewn for giving the requisite motions to the
said picker or pickers, and to the cutters as the said means may be varied without
departing from the nature of my invention
