PROVISIONAL SPECIFICATION left by the said William Frederick
Bateman at the Office of the Commissioners of Patents, with his
Petition, on the 7th April 1874.
I, WILLIAM FREDERICK BATEMAN, of Low Moor, in the County of
York, Card Maker, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR MAKING SPACES IN
CONDENSER DOFFERS," to be as follows:-
This Invention relates to a machine for crushing down or depressing
the card teeth on a condenser doffer clothed with fillet card" in such
a manner that the teeth thus crushed are laid quite flat on the face of
the doffer. The crushed teeth are to form the space between the rings

page_text: passing round the doffer, and are crushed down at intervals to form the
width of rings required. This operation has been hitherto performed
by hand or by apparatus for clipping out the teeth required to make
the necessary spaces.
My improvement consists of a gangtree or other framework which can
be fixed across the frame of a condensing carding engine, upon which is
fitted a slide rest worked from end to end of gangtree by means of a
screw or rackwork similar to a slide rest lathe motion. Upon this rest
is arranged a small vertical steel tongue working at right angles to the
axis of the doffer between two guide lips by means of a tappet or
eccentric and shaft, to which motion is imparted by means of a square
shaft passing through hollow shaft upon which tappet or eccentric is
fixed. To this eccentric or tappet is imparted a high velocity in order
to give the steel tongue the necessary motion to beat down flat upon the
face of the doffer the teeth of the card. The tongue and guide lips are
of the width of the desired space by means of the adjusting screw, as.
in the case of a slide rest, the tongue and guides are made to enter
amongst the teeth. The rapid reciprocating motion of the tongue
flattens them down as the guides gather the teeth and press them into
position for the crushing process. The doffer is caused to revolve slowly
until it comes to the place from which it started, when a complete space
is made all round the doffer. The slide is then travelled laterally into
the position of the next space, and the above process repeated until the
required number of rings and spaces are made.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Frederick Bateman in the Great Seal
Patent Office on the 7th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FREDERICK BATEMAN, of Low Moor, in the County of York, Card
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors;

page_text: give and grant unto me, the said William Frederick Bateman, Her special
licence, that I, the said William Frederick Bateman, my executors;
administrators, and assigns, or such others as I, the said William
Frederick Bateman, my executors, administrators, and assigns, should at
any time agree with and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR MAKING SPACES IN
CONDENSING DOFFERS," upon the condition (amongst others) that I, the
said William Frederick Bateman, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Frederick Bateman, do
hereby declare the nature of my said 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 a machine for crushing down or depressing
the card teeth on a condenser doffer clothed with "fillet card" in such
a manner that the teeth thus crushed are laid quite flat on the face of
the doffer. The crushed teeth are to form the space, between the rings
passing round the doffer, and are crushed down at intervals in order to
form the width of rings required. This operation has been hitherto
performed by hand or by apparatus for clipping out the teeth required
to make the necessary spaces.
My improvement consists of a gangtree or other framework which can
be fixed across the frame of a condensing carding engine, upon which is
fitted a slide rest worked from end to end of gangtree by means of a
screw or rackwork similar to a slide rest lathe motion. Upon this rest
is arranged a small vertical steel tongue working at right angles to the
axis of the doffer between two guide lips by means of a tappet or
cccentric and shaft, to which motion is imparted by means of a square
shaft passing through hollow shaft upon which tappet or eccentric is
fixed: To this eccentric or tappet is imparted a high velocity in order

page_text: to give the steel tongue the necessary motion to beat down flat upon the
face of the doffer the teeth of the card. The tongue and guide lips are
of the width of the desired space by means of the adjusting screw, as in
the case of a slide rest, the tongue and guides are made to enter amongst
the teeth. The rapid reciprocating motion of the tongue flattens them
down as the guide gathers the teeth and press them into position for the
crushing process. The doffer is caused to revolve slowly until it comes
to the place from which it started, when a complete space is made all
round the doffer. The slide is then travelled laterally into the position
of the next space, and the above process repeated until the required 1
number of rings and spaces are made.
I will now proceed to describe the accompanying Drawings in which
like parts are indicated by like letters and figures.
Fig. 1 is a front elevation of my improved apparatus, shewing square
shaft gangtree rack and screw; Fig. 2 is a plan of the same; Fig. 3 is a 1
back view of carriage with gangtree shortened; Fig. 4 is an end view
shewing the change wheels and index plate; Fig. 5 is a section through
line A, B, in Fig. 2.
Fig. 6 is an enlarged section of steel hammer or tongue and guide
shewing mode of gathering and flattening teeth down to face of cylinder;
Fig. 7 is a front view of hammer and guide; Fig. 8 is a plan of the
same.
In Fig. 1, A, A, is a metal gangtree having the top part A', A', planed
level and parallel; C, a carriage made to fit A', A', and slide from end
to end of gangtree; B, B, are brackets secured to cach end of gangtree
A, A; B', B', are brackets secured to carriage C; D, a square shaft,
driven by pulley D¹ keyed on one end of the same, revolves in cylindrical
bushes b, b, b, b, having a square hole in centre to fit shaft D, and runs
in top of brackets B, B, and B', B¹; E, an eccentric on the same shaft
revolves between projecting brackets F, F, secured to slide F, working
in groove ƒ formed in carriage C; G, a hand wheel fixed on shaft G¹, on
.which is also secured toothed wheel H gearing into wheels H¹ and H²;
J, a handled lever connected to toothed spur wheel K, revolves on
centred stud J', and gears into toothed wheels K' and K², which is
secured by nut M to end of screw S, S, working in brackets A², A², cast
to and forming part of gangtrec A, A; M', a nut on the other end of
screw S, S, for keeping the same in proper position; S¹, a lever for

page_text: which moves in direction of arrow on Fig. 6. After one revolution of
cylinder reverse hand wheel G and draw back hammer U and guide U$
clear of the card teeth, then lift up stop Js out of index plate J² and
turn winch J, which revolves toothed gear and screw S, S, and travel
carriage C, to the required pitch, then drop J³ into prepared spaces in
index plate J to prevent the possibility of carriage moving, then turn
hand wheel D and travel slides towards card, when guide U and
hammer U will beat down another circle the same depth and space
required.
