PROVISIONAL SPECIFICATION.
Improvements in Card Setting Machines.
We, ABEL BLACKBURN and JOSEPH ROBERTS TETLOW, of the Firm of A. Black-
burn and Company. Tofts Mill. Cleckheaton, in the County of York, Card Setting
Machine Makers, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to construct an efficient and perfect spacing
motion for endless screw sheet setting machines for cotton tops or other cards,
so that there is no possibility of irregularity in either setting or spacing.
Upon the worm shaft which operates the sheet rollers, we preferably fix two
ratchet wheels. one wheel is for spacing and has twice the number of teeth as
the other. which is for setting. the spacing wheel is also loose upon its shaft,
and has attached to one side an adjustable cam, by the adjustment of which the
width of space between each strip of cards may be regulated as desired.
Engaging with these ratchet wheels are two catches. These catches are operated
simultaneously at each reversing of the carriage by the take up lever of the
roller carrying the sheet.
In the operation of these catch wheels, the catches only move the said wheels.
one tooth at once, the wheel having the larger number of teeth being prevented
from exceeding this. by a bracket and stud, operating within a fork; this stud
is for adjusting the movement of the aforesaid bracket and catch according
to the length of tooth on the catch wheel.
We preferably form the take up lever with a suitable end, which moves in and
out of contact with the cam upon the catch wheel, at each reversal of the carriage.
and, as this catch wheel revolves, it eventually brings the cam into position, which
presses back the take up lever, which has a stud fixed upon it with an inclined
face, this stud as the lever is forced out by the cam depresses one end of a second
lever and lifts the catch out of gear with the catch box or wheel which operates
the screw, and puts the same out of action: the carriage therefore remains
stationary while the tappet on the main or tappet shaft operates the catches
and catch wheel, until the face of the cam, clears the take up lever, when the
same falls and immediately puts the setting mechanism in operation.
When the required number of teeth has been set in the sheet, the face or nose
of the cam again presses back the take up lever, throws the setting mechanism
out of gear, and the sheet is moved by the spacing mechanism as before described.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The object of our invention is to construct an efficient and perfect automatic
spacing motion for endless screw sheet or other eard setting machines for cotton
tops or other cards, so that there is no possibility of irregularity in either setting
or spacing.
DESCRIPTION OP DRAWINGS.
Fig. 1 is a plan view of one end of an endless serew sheei enrd setting machine
with our improvements applied.
Fig. 2 is a sectional end view of Fig. 1.
Fig. is an end view of catch box, and means for operating same.
Fig. is a plan of spindle actuating the levers operating upon the caiches of
the catch box when stopping the carriage.
Fig. 5 is a side view of cam attached to spacing wheel.
pou the worm shaft A which operates the sheet rollers, we preferably fix two
ratchet wheels B C. one wheel B is for spacing and the other wheel is for
setting the number of teeth in the spacing wheel B, varying with the number
in the setting wheel C according to the width of space or card required, for
example, if a sheet should require one inch setting and two inch spacing, and
the setting wheel requires to have ninety teeth, the spacing wheel will need to
have two hundred and seventy teeth, that is, double the number of teeth adding
in what is required for setting, as the spacing is twice the width of the setting:
if one inch setting, and an inch an a half spacing is required, then the spacing
wheed will require two and a half as many teeth as the number required for setting
but in every ease whether the space be more or less in depth to the setting. this
calculation must be worked out in order that the teeth in each wheel bear a
proportionate relation to each other. The spacing wheel B is preferably loose
upon its shaft, and has attached to one side an adjustable cam 1), the face or
nose of this cam D is adjustable by means of slais D² and holis D' so that
it may be lengthened or shortened to correspond with the width of spacing and
setting required.
Also, in operation, these catch wheels B. G only move one tooth at once at each
reversing of the setting mechanism. and to prevent the spacing wheel B excred.
ing this, we fix a brake F upon the hoss of the said space wheel, one arm of
which works within a fork or bracket the movement of this arm being adjusted
by a serew, to the other arm of the brake is attached a spring F
Engaging with and operating these ratchet or catch wheels BC, are two spring
catches E. mounted upon a lever G loose upon the worm shaft A, these eniches E
are operated simultaneously at each reversal of the carriage by the take up lever H.
and operate or move the roller carrying the sheet, the take up lever is pivotted
at 11.
Underneath the take up lever I is a second or eam lever X, pivotted at X,
attached to which is a projection II, which is operated upon by a tappet on the
cam or main shaft K. This projection is moved on to the tappet or cam I at each
reversal of the carriage, by means of a lever or finger L, upon the reversing shaft M
acting upon a eam projection L' on the lever N.
Mounted upon the machine frame is a sliding spindle or stud P. which has
formed upon it at suitable distances apart, preferably two inclines P, one end
of this stud hears against the turned up end N₁ of the cam lever N, upon which
is fixed a notched stud Na bearing against the cam D upon the spacing wheel :
pressure of the spindle Pupon the lever N is maintained by means of the spring 1
pon each side of the catch box R are mounted two pivotted levers S. one end of
pach lever resting upon the inclines Pt of the sliding stud P. the other ends project.
one underneath a projection T of the entch T of one catch wheel i, and the other

page_text: rests upon a projection VI of a catch V of the other catch wheel W of the
catch box.
The action is as follows:--When the machine is setting and the carriage
reverses, the lever or finger L upon the reversing shaft M. strikes the cam L'
upon the cam lever N. and moves the projection H' on to the tappet J. simul-
taneous with this operation, the cam lever N also moves the notched stud N³ clear
of the cam upon the spacing wheel, and at the same time forces out the sliding
stud P, whose inclines P. acting upon the pivotted levers S cause the same to pull
or raise the catches TV, clear of the catch wheels U W upon the catch box R.
putting such wheels Wont of action and stopping the screw X. consequently
the carriage remains stationary. Immediately this has been effected. the cam
or tappet apon the cam of main shaft K, strikes the projection II. lifting
the take up lever H. which raises the catches E and moves the catch wheels B,
Ca tooth, at the same time moving the roller carrying the sheei a sufficient dis-
tance for another row of teeth. As the tappet J revolves and the projection H'
upon the lever X comes opposite the cut away part of the tappet, the tension of
the spring returns the sliding stud P. which being in contact with the lever N
simultaneously moves the said lever back to its original position, causing the
catches TV to re-engage with the catch wheels U W. "so operating the screw and
moving the carriage for another row of teeth.
When the setting is completed and it is desired to space for the next strip.
the projection upon the lever X is operated upon, and the said cam lever N
forces out the sliding stud P. stopping the carriage as before described, but when
the famnet I should release the said projection H', the cam lever X and sliding
stud P are prevented from returning to their original positions by the nose D¹
of the cam D upon the spacing wheel B, which has worked round for this purpose.
Consequently the take up lever I continues to be operated by the tappet J.
lifting the catches E. and moving the catch wheels B C and roller carrying the
sheet the required distance: when the desired space has been obtained the cut
away part of the cam D will then present itself, and the end of the sliding stud
being at liberty to shoot into same, does so, and simultaneously returns the
cam lever X. and projection II throwing the spacing mechanism out of action,
the catches TV, then immediately engage with the catch wheels U W. of the
catch box R. starting the carriage, and setting mechanism for the first row of the
next strip.
By providing the spacing wheel B with a brake F. adjustable brake arm F¹,
and spring such wheel is kept under control and can only move one tooth at
once unless two teeth upon such wheel are the same length as one tooth upon the
setting wheel. but where the length of one tooth on the setting wheel is greater
than one tooth of the spacing wheel, the action is as follows: when the catches
move the catch wheels it will be necessary for the catch upon the setting wheel to
move the length of one tooth, the catch upon the spacing wheel, (the teeth of
which are less), will have moved more than the length of one tooth. therefore when
the catches are released and fall, the spring pulls the wheel B and brake back.
until the tooth engages with the catch E. By raising or lowering the adjusting
stud F the work of the aforesaid spring is limited to the length of the tooth on
the spacing wheel.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is-
1. In spacing motions of card setting machines. the combination of lever X
having projections L, H. and notched stud N3. sliding stud or spindle Pupen
