page_text: LETTERS PATENT to Henry A. Chapin, of 97, Cheapside, London,
Engineer, for the Invention of "IMPROVEMENTS IN SPINNING AND
TWISTING MACHINES.”
Sealed the 9th October 1874, and dated the 15th April 1874.
PROVISIONAL SPECIFICATION left by the said Henry A. Chapin at the
Office of the Commissioners of Patents, with his Petition, on the
15th April 1874.
I, HENRY A. CHAPIN, of 97, Cheapside, London, Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SPINNING
AND TWISTING MACHINES," to be as follows:-
This Invention for improvements in spinning and twisting machines
relates to certain novel improvements in devices for drawing and twisting
materials, and finishing the same at one operation by the employment of
a drawing and twisting device in combination with a ring traveller,
wherein the parts are freely lubricated, and the oil effectually prevented

page_text: from escaping from the oil chambers in which they are run, and wherein
the ring and traveller are not depended on to give any twist or tension
to the material, but serve simply as a means by which the material is
wound upon the bobbin.
The drawing and twisting device is composed of an oil cup, up which
passes a tube for the passage of the yarn so as to isolate the yarn from
the oil; round this fixed tube is the hollow spindle carrying the standard
or yarn carrier and rollers, rotated from a driving shaft as the yarn is
drawn and twisted in its passage through these rollers it is taken to or
round a drawing pulley or V grooved pulley also rotated on a shaft or
hollow tube running concentrically with the yarn carrier tube, thence
the yarn is carried down the central hollow shaft to the winding device.
The bobbin being rotated is surrounded by a ring having an upward and
downward motion. To the circular neck of this ring is clipped a cut
ring or traveller, which clasping round the neck closes sufficiently
round the ring to be retained there, but still free to rotate round the
neck of the ring. Through this traveller the yarn passes on its way to
the bobbin, the novelty here being this latter well known. device of the
ring and traveller in combination with the drawing and twisting device
above described, with independent building motion for each spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry A. Chapin in the Great Seal Patent Office on
the 13th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 'I, HENRY
A. CHAPIN, of 97, Cheapside, London, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth 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, give
and grant unto me, the said Henry A. Chapin, Her special license that I,

The following description of my Invention will enable others skilled
in the art to understand it :-In the accompanying Drawings A represents
part of the frame of the machine for supporting the drawing, spinning,
and winding devices; B, B¹, represent ring brackets supporting two oil
cups C, C¹, secured fast therein by means of set screws; D represents a
vertical driving shaft, which is supported back of the frame A by
brackets b, b¹; on this shaft D are keyed four pulleys D', D", F, and P,
and also a worm screw d. The pulley P receives motion from any
suitable prime mover and gives rapid rotatory motion to the shaft D.
The pulley D' communicates motion to a pulley E, which is on a hollow
stem in oil cup C, through the medium of a belt e. The pulley D",
which is somewhat smaller than pulley D', communicates motion to
a pulley E', which is on a hollow stem s through the medium of a belt e',
and the pulley F communicates motion to a pulley F" on the bobbin
spindle S through the medium of a belt f. The worm screw d com-
municates a slow rotatory motion to a vertical shaft g, through the
medium of a worm wheel d¹, worm screw k¹, and worm wheel k. The
shaft G, which is arranged in front of frame A, is sustained between
two vertically adjustable bearings 9*, 9*, and into this shaft right and
left intersectings helical grooves are cut, in which is received a pin p in
a block g; this block moves up and down on shaft G and carries with
it a ring bracket g², in which is fixed the neck of a ring i, around which
ring revolves a traveller j shewn in Figures 1 and 2.

of the grooves g in the shaft G, and the pin p in the block g¹ that the
traveller ring is moved up and down for winding the yarn on the
bobbin S¹ in regular courses. The oil cup C has a cap c secured upon it,
on the bottom side of which is formed an open elongated bearing c³ for
the hollow stem q, and centrally into the upper side of which cap is
formed a circular cup 5, which communicates with the interior of the

cap 5 is an elevated bearing for the hub of pulley E, which hub runs in
the cup 5, as shown in the Figure 3. The stem of q, on which pulley E
is keyed, extends through cap c and its open extension c¹, and has its
bearing at the bottom of the cup, consequently, when this stem is
rapidly rotated, it carries oil up between itself and the two bars of the
extension c*, and into the cup 5 on the cap c, from which latter the oil

page_text: returns into the cap c, again through the passages 4, 4. The stem q is
prevented from rising from its seat by means of screw 2, which is tapped
through one of the bars of the open extension c', and which onters an
annular groove 3 made into said stem q. The pulley E has a cup 7
formed into its upper side, which communicates with the cup 5 through
passages Y, and surrounding the opening leading into the stem q is a
raised bearing, on which is supported the hub of pulley E. The
pulley E' rotates around a hollow stem 8, which extends down nearly to
the lower end of the stem q, which is secured to this stem q by means
of a key 9 shown in Figure 3. Into the upper side of pulley E' a
cup 8 is formed which communicates with the cup 7 in pulley E by
means of passages 6. In this cup 8 and surrounding the opening
leading the stems is a raised bearing for a shoulder 8', which is formed
on the stem & near its upper end. This stem 8 receives on its tension
plates o and a set nut r as shown in Figure 3. The stems with its
stem revolves around a fixed hollow stem v, which is secured to the
bottom of the cup C by means of a nut u, and which rises vertically
nearly to the upper open end of the stems and receives through it the yarn
on its way to the bobbin winding device herein-after explained. On the
top of the pulley E' and firmly secured thereto is a short standard sup-
porting two yarn carrying pulleys n, n, and opposite the standard is
curved standard T having pivoted to it two yarn carrying pulleys t,
annanced directly over the stems through which the varn is

page_text: This cap
is also constructed with a circular cup m in its upper side, which
receives the oil carried up to lubricate the stem S² of the spindle S, and
returns this oil back into the cup C¹ through passages m'; the lower
reduced end 12 of the stem S³ turns in the step 13. The part S2 is straight
or cylindrical, and this part, by reason of the rapid revolution of the
spindle S, carries the oil with such force against the edges of the
openings in the extension c³ that it is made to rise and lubricate the
bolster. The hub of the pulley F is received into a cup m and has a
bearing upon a raised annular portion of cap c³, which surrounds the
hole through this cap.
It will be seen that the stem S2 of the spindle S is inclosed in the
cup C', and that the oil which rises and lubricates this stem is received
into the cup m and returned back into the cup; also that the oil cannot
escape or be thrown from the parts being lubricated however rapidly the
spindle be rotated.
It will be observed that the ring and traveller are of the well known
kind, but in my machine this ring and traveller are not employed nor
depended upon for tension or required twist, as these are produced by
the drawing and twisting device above it, and by which the yarn is
delivered to the traveller ready to be wound upon the bobbin, con-
sequently the ring and traveller are employed solely as a winding device.
Having described my Invention, what I claim as new and desire to
secure by Letters Patent is,-
1. A drawing and twisting device combined with an oil reservoir and
having oil receptacles and discharge passages in and through revolving
pullies E¹, E, and in which the long hollow hubs of said pullies are
arranged relatively to each other and to the upright hollow shaft which
carries on its upper end the drawing pulley o as described..
2. The combination of the specified drawing and twisting device with
an oil reservoir, having attached to it the stationary tube v, which passes
up through the moving parts and protects the yarn from being soiled by
the oil as it passes through on its way to the ring and traveller, sub-
stantially as described.
3. The combination of the drawing and twisting device, ring, and

traveller wherein the drawing and twisting device runs at the same
speed as the spindle, and puts all twist into the yarn before it is acted by
the ring and traveller and spindle.
