page_text: LETTERS PATENT to Charles Walford Vick and Joseph Cooke, of the
Firm of Cooke, Vick, and Co., of Dudbridge Patent Machine Works,
Stroud, in the County of Gloucester, for the Invention of "IMPROVED
Sealed the 27th August 1872, and dated the 25th April 1872.
PROVISIONAL SPECIFICATION left by the said Charles Walford Vick
and Joseph Cooke at the Office of the Commissioners of Patents,
with their Petition, on the 25th April 1872.
We, CHARLES WALFORD VICK and JOSEPH COOKE, of the Firm of
Cooke, Vick, and Co., of Dudbridge Patent Machine Works, Stroud,
in the County of Gloucester, do hereby declare the nature of the said
Invention for "IMPROVED MACHINERY FOR FEEDING PREPARING AND CARDING
ENGINES," to be as follows:-
This Invention relates to a novel construction of apparatus for laying
a sliver or roping across the feeding apron of preparing and carding
engines. The carriage in which the delivery rollers are mounted slides
over a bridge consisting of a straight bar grooved at its upper and lower
edges to form a guide for the carriage. This bar is set transversely of

page_text: the feed apron and at any desired angle thereto. The carriage derives
its traverse motion from an endless chain in the usual way. Mounted
on the carriago is a rocking frame provided with bearings to receive the
axles of the delivery rollers. These rollers are severally fitted with
radial blades which interlock like the teeth of spur gearing to ensure t
the rotation of the two rollers (no matter which of the two is for the
time being the driven roller) and to put a drag or bite on the sliver
which passes down between the rollers. Fixed to and pendent from the
rocking frame is a lever, which is intended as the carriage reaches the
end of its traverse in either direction to strike against a fixed stop fitted 1
to the bridge. The bridge also is provided with a long horizontal rack,
into the teeth of which gear spur wheels, mounted respectively on the
inner ends of the roller axles. Affixed to the top of the carriage is a
spring having two notches, and a catch forming the continuation of the
lever of the rock frame is intended to take into these notches and hold 1
the rock framo in the position into which it is rocked. The centre of
motion of the rock frame is between the two rollers, and when it is
rocked one spur wheel will be thrown into gear with the rack and the
other out of gear. The traverse of the carriage causes the fixed rack to
give rotary motion to the delivery rollers through one or other of their a
spur wheels. Thus as the direction of traverse of the carriage is reversed
the position of the gear wheels will be reversed (one being thrown into
and the other out of action) by the tipping of the rocking frame (through
the lever striking against the fixed stop), and the consequence will be
the continuous rotation of the feed rollers in one and the same direction,
and the continued delivery of the sliver in parallel lines on to the
travelling feed apron.

Great Seal Patent Office on the 25th October 1572.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
WALFORD VICK and JOSEPH COOKE, of the Firm of Cooke, Vick, & Co.,

and ascertain the nature of the said Invention, and in what manner the
samo was to be performed, and cause the samo to be filed in the Great

NOW KNOW YE, that we, the said Charles Walford Vick and Joseph
Cooke, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
5 ascertained in and by the following statement, reference being had to
the Drawing hereunto annexed and to the letters and figures marked
thercon (that is to say):→
This Invention relates to a novel construction of apparatus for laying
a sliver or roping across the feeding apron of preparing and carding
enginos, the object being to ensure a more equable delivery of the sliver
than heretofore.
In the accompanying Drawing, Fig. 1 shews in front elevation the
approved feed apparatus, the middle portion being omitted to contract
the length of the Drawing; Fig. 2 is a plan view of the same; and
3 Fig. 3 is a transverse sectional elevation taken in the line 1, 2, of
Hie

page_text: A, A, is the travelling carriage on which the delivery rollers are
mounted. This carriage slides over a bridge B consisting of a straight
bar grooved at its upper and lower edges to form a guide for the
carriage, and it is made fast to brackets B' which aro bolted to the
framing of the feed frame or carding engine. This bar is set trans-
versely of the feed apron, and at any desired angle thereto. The carriage
is furnished with a vertical slot to receive a pin c which projects from
a link of the endless chain C supported upon chain wheels C', and it is
through the traverse of this endless chain that the to-and-fro motion of
the carriage is derived, as is well understood by persons conversant with
this class of feeder. Mounted on the carriage A is a rocking frame D pro-
vided with bearings to receive the axles of a pair of delivery rollers E, E.
These rollers are severally fitted with radial blades which interlock like
the teeth of spur gearing to ensure the rotation of the two rollers (no
matter which of the two is for the time being the driven roller), and to
put a drag or bite on the sliver F (Fig. 1) as it passes down between
the rollers. Fixed to and pendent from the rocking frame is a lever E¹,
which is intended as the carriage reaches the end of its traverse in
either direction to strike against a fixed stop fitted to the bridge, and
thereby effect the rocking of the frame for the purpose to be presently
explained.
G, G', Fig. 2, are the fixed stops against which the pendent lever E¹
strikes on the completion of the traverse of the carriage over the
bridge B. This bridge is provided with a long horizontal rack H, into
the teeth of which gear spur wheels I, I, keyed respectively on the inner
ends of the roller axles. Affixed to the top of the carriage is a spring K
having two notches a, into which takes a catch 6 forming the con-
tinuation of the lever E¹ of the rock frame. By this arrangement the
rock frame is held firmly in the position into which it is rocked. The
centre of motion of the rock frame is between the two delivery
rollers E, E, and when it is rocked one of the spur wheels I will be
thrown into gear with the rack and the other out of gear. The traverse
of the carriage causes the fixed rack to give rotary motion to the
delivery rollers through one or other of their spur wheels, thus as the
direction of traverse of the carriage is reversed the position of the gear:
wheels will bo reversed also (one being thrown into and the other out
of action) by the tipping of the rocking frame (through the lever E'
striking against the fixed stop), and the consequence will be the con-

page_text: ținuous rotation of the delivery rollers in one and the same direction,
and the continued delivery of the sliver in parallel lines on to the
travelling feed apron.
Rotary motion is given to the chain wheel C³ by the bevil and spur
gears L, M, which are driven by a band passing over the pulley N.
We may remark that instead of the rack H and spur wheels I friction
gearing may be employed if thought desirable for driving the delivery
rollers.
Having now set forth the nature of our Invention of "Improved
Machinery for Feeding Preparing and Carding Engines," and ex-
plained the manner of carrying the same into effect, we wish it to be
understood that under the above in part recited Letters Patent wo
claim,―
First. The means above described for supporting the carriage in its
traverse motions.
Secondly. The arrangement above described for ensuring the rotation
of the delivery rollers in one and the same direction during the to-and-
fro traverso of the carriage.
In witness whereof, we, the said Charles Walford Vick and Joseph
Cooke, have hereunto set our hands and seals, the Twenty-third
day of October, in the year of our Lord One thousand eight
hundred and seventy-two.
