JOSEPH. ROBERTS. TETLOW Card Manufacturer Springwood Cleckheaton ABEL.
BLACKBURN Machine Maker No. 6. Roberts Square, Cleckheaton do hereby
Iz
declare the nature of this invention to be as follows:-
Our invention relates to an improved Twill or Cam wheel motion for Cardig
Sheet Machines for setting Twill Cards for Wollen Worsted Cotton Flax and
Silk or any other Card Clothing of any discription. Consists of a Cam or Twill.t
wheel drivin same end as Catch Box by tapit and lever or any other tapit; in.
conjunction with each other. Which we claim as not been done before.
The tappit is fixed on main round driving Shaft (The Shaft is one portion
round for about 16" from end of driving Balance Wheel, then lengthened the
required length of Machine constructing with a three cornered bar.)
The tapit which works our improved lever is fixed on the round part of Shaft. is
We have a lever which is put into contact with tapit when the Machine has i
travelled the distance required with the same arrangement at present, which!
causes the machine to reverse.
پینز
When this is taking place it causes the tapit to lift the lever and drive a.,
Catch wheel (Catch wheel is cut the same way as any ordinary catch wheel)! [
This wheel is fixed on same shaft as the Cam wheel or Twill wheel (Cam or
Twill wheel is a circular wheel with steps cut at different heights down the
outside of wheel) which is connected to work in the ordinary way to allow the
jaws which hold the material during the process of setting to slide into position"
of each step when driven with lever from the tapit causing a Twill Card to be
formed on the material in process.

We, JOSEPH ROBERTS TETLOW of Springwood Card Manufacturer, and ABEL
BLACKBURN of Roberts Square, Machine Maker, both in Cleckheaton in the
county of York. 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:-
The object of our invention is to improve the twill, by lessening the vibration,

page_text: also, we greatly improve the speed consequently considerably more work is done
than by machines having the ordinary twill motion.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an end elevation of our improved apparatus or mechanism for
operating the twill in card setting machines.
Fig 2 is a plan of Fig 1.
Upon the main driving shaft A of the machine, preferably at the driving end,
adjacent to the ordinary driving pulleys for operating the said shaft A is fixed
the ordinary taking up tappet B, for operating the mechanism for lifting the
jaws holding the material during the operation of setting, the tappet B operates
upon the lever C at intervals, that is, upon the reversing of the traverse of the
card setting mechanism, this lever C by means of catch 1), moves the catch wheel
E, which operates the ordinary mechanism for lifting the jaws; also pivotted
upon the machine frame F', is a bell crank lever G, upon this bell crank lever G,
is a spring catch H, engaging with and operating a catch wheel J upon the same
shaft K as the twill or cam wheel L, this catch wheel J operates upon the cam
wheel L, which operates upon a projection or stud M moving the jaws laterally
for forming the twill. The cam wheel by our arrangement operates upon the
projection or stud M of the jaws in such a manner that when the twill is com-
pleted, the said stud moves up a quick incline L' on the cam wheel L, moving
the jaws into position for the next twill; in the old method the stud descended
the incline causing a lot of vibration of the jaws and material, consequently
irregular setting of the twill.
The action is as follows:-When the card setting mechanism has arrived at
the end of its traverse, and is reversed in the ordinary way, that is by the cam
upon the side of the frame of the card setting mechanism coming in contact with
and depressing the fingers upon the reversing shaft A which operates the ordinary
reversing mechanism, the cam B operates upon the lever C, for operating the
taking up mechanism for lifting the jaws, simultaneously with this operation
the lever C moves the bell crank lever G and this lever, in conjunction with the
catch Hand catch wheel J, operates upon the cam wheel L, which moves the
jaws laterally for the purposes before described.
Having, now particularly described and ascertained the nature of our said
invention and in what manner the same is to be peformed we declare that what
we claim is: -
401120
1. In card setting machines fixing the mechanism for operating the twill
wheel, at the driving end of the machine, and operating the same by and
2. In card setting machines, the use and employment of lever G, catch H,
simultaneous with the taking up or lifting mechanism, in the manner and for
the purposes substantially as shown and described.
and catch wheel J, for operating the cam or twill wheel L for forming the twill,
operated by the lever C, and tappet B, of the lifting mechanism, in the manner
and for the purposes substantially as shown and described.
