Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WHITING
HAYDEN, of Willimantic, in the Town and County of Windham, and State of
Connecticut, of the Republic of the United States of North America, send
greeting.
WHEREAS Queen Victoria, by Letters Patent under the Great Seal of
Great Britain, bearing date at Westminster; the Tenth day, of October, anno
Domini One thousand eight hundred and fifty, did give and grant unto me,
the said Whiting. Hayden, my exors, admors, and assigns, especial license, full
power, sole privilege, and authority, that I, they, or such others as I or they,
should at any time agree with, during the term of years therein mentioned;"
should and lawfully might make, use, and exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "AN IMPROVED
REGULATOR OR APPARATUS FOR REGULATING. THE DRAFT OF THE-SLIVER, OR THE
MACHINE TERMED THE DRAWING FRAME;" in which said Letters Patent there is
contained a proviso, that I shall particularly describe and ascertain the nature
of my said Invention, and in what manner the same is to be performed, by
an instrument of writing under my hand and seal, to be enrolled in the High
Court of Chancery- within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as, reference being there-
unto had, will more fully and at large. appear.
NOW KNOW YE, that in compliance with the said proviso, the nature
of my Invention, and the manner in which it is to be performed, are par-
ticularly described and ascertained in and by the following Specification or

page_text: instrument of writing, to the Drawings annexed to or accompanying the same,
and to the letters, figures, and references thereof :-
Of the said Drawings, Figure 1 is a perspective view of the drawing regulator,
or apparatus for regulating the draft of the sliver; Figure 2 is a plan of the
top of the same; Figure 3 is a vertical section of it; Figure 4 is a vertical
section taken through the screw nut, belt guides and cones to be herein-
after described. Similar letters in the several Figures refer to corresponding
parts.
The nature of my Invention consists in the application of a certain apparatus
or combination of mechanical devices to the drawing frame, by means of which
the speed of the rolls which accomplish the draft, (or draught,) upon the sliver
of cotton, is regulated by the size or volume of the said sliver of cotton itself,
thus causing the work of the machine to be uniform and perfect as delivered by
the rolls, and the apparatus to effect the same to be "self-acting." To accom-
plish this, I apply to the drawing-frame A a moveable or slowly osillating
trumpet or tube B, of sufficient size internally to permit the passage of the
sliver of cotton, and at the same time small enough to be instantly affected
in its position by the volume of the said sliver of cotton; the effect, when the
sliver is too large in diameter, being to throw the trumpet or tube forward,
but when it is too small in its diameter the effect is to permit the trumpet or
tube to be moved backwards by the gravity of the weight C; the trumpet
retains its proper position when the sliver is running at its proper size; this
being caused by the action of the weight C, which is suspended from the
lower or sharp end or arm D₁ of the lever D, the said arm being made to form
either a right or obtuse angle with the other arm of the lever. This lever, by
means of a broken or jointed bar or toggles E, E, is connected with the
shaft F, upon which is a geer G, that is adapted to work into either of the two
geers H, I, according to the position of the trumpet lever D, D', and is moved
by the upright shaft K through the intervention of two bevilled geers 5 and 6.
The said shaft K. also imparts motion to the back or front drawing rolls L, L,
r, r, and this by means of the small bevel wheel 3, upon the upper end of it,
being made to engage with a bevelled geer 4, placed on the drawing axle
of either set of such rollers. There is a third geer M, which works into a
geer I, and is connected with the screw shaft N, upon which shaft there is
a nut O capable of traversing the entire length of the screw; to this nut are
attached two arms P, P, which are terminated by belt guides Q, Q; for regu-
lating and shifting the position of the belt V, V, upon the cones R, R, the
upper or driving cone receiving its motion directly from the pulley S through
the geers T, t, T.

page_text: The operation of the machine is thus:-The sliver of cotton in its passage
from, the drawing rolls, through the tube or trumpet B, to the delivering rolls
U, U, on becoming too large draws the said trumpet B forward, towards the
said delivering rolls U, U, and throws the small geer G into match with the
geer H, thus instantly giving motion to the chain of geers H, I, M, which
operates the screw shaft N, and shifting, the belt V upon the cones R, R, in
such manner as to reduce the speed upon the back drawing rolls; and this by
means of the bevil wheel 1 on the cone shaft, matching into bevel wheel 2 on
shaft K, on whose upper end is a bevel geer 3, which matches into a bevel geer
4 on the shaft of the lower back roller. The speed of the front drawing.
rollers continuing unchanged, they consequently produce a greater draft upon
the sliver, and reduce it in size, until the trumpet mouth is relieved and
returned to its proper position by the action of the weight C. When the
sliver of cotton becomes too far reduced in size, the reverse of the operation
above described is produced, by the working of the geer G into the geer I.;
G
and so also, when the sliver of cotton is moving at its proper size, the geer
plays freely between the said geer H and I, so as not to interfere with either
of them.
What I claim as my Invention is, the combination of the following elements,
or their mechanical equivalents, viz.,-the tube or trumpet B; the lever D,
D'; the weight C; the jointed bar E, E; the oscillating shaft F and pinion G;
the three, or any other suitable number of geers H, I, M; the screw shaft N;
the nut O; the arms P, P, with their belt guides Q, Q; the belt V; the cones
R, R; the shaft K; and the bevel geers 1, 2, 3, 4, 5, 6; the same being for
changing and regulating the speed of the rolls, and. equalizing the drawing or
the making the sliver the required size, substantially in the manner described
in the foregoing Specification.
In witness whereof, I, the said Whiting Hayden, have hereunto set my
