A communication by WALTER TAYLOR HANSON, of Macon, in the County
of Bibb and State of Georgia, United States of America, Cotton Manu-
facturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster, 118 New Street, Birmingham
in the County of Warwick, and 322 High Holborn in the County of Middlesex,
Civil Engineer, 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 this invention is to provide a mechanism, whereby a regular and
uniform reciprocating motion may be produced from a shaft revolving continuously
in one direction, the same being especially, though not exclusively, designed for
operating the traverse-bars of winding and spooling machines. In some machines
of this character, the traverse-bar extends from end to end of the machine and
carries a series of yarn-guides which are arranged on the bar in respect to the
revolving spools or cop-tubes to which the yarn is delivered. Hence any irregularity
in the movement of the bar affects the uniformity of the winding of the yarn on the
several spools or tubes. To overcome this objection, there have been used in
certain machines independent cam-operated traverse devices for the individual
yarn-guides, but that construction is complicated, expensive, and unreliable. This
invention, however, provides a simple and efficient means whereby the single
traverse-bar, with its series of yarn-guides, may be operated in a manner to effect
a uniform and regular feeding of the yarn to the several cop-tubes, as will hereinafter
appear.
The invention, as generally stated, comprehends a wheel or head provided with
a radially-reciprocative stud or roller, in combination with a face-cam to which said
stud or roller is fitted, and a connection between said stud or roller and a
longitudinally-reciprocative bar, whereby during the relative operation of said
wheel or head and the cam, the stud or roller will traverse the cam and corre-
spondingly actuate said bar. The cam is shaped to effect the reciprocation of the
bar at a regular and uniform rate of speed, as will be hereinafter described.
In the annexed drawings,
Figure 1 is a side elevation of the mechanical movement as applied to a spooling
or winding machine, the head of the casing with its immmediate connections being
removed and shown in Fig. 1ª.
Figure 2 is a full section, as on the line - of Fig. 1.
Figure 3 is a transverse section on the line y-y of Fig. 14.
Figure 4 is a modification hereinafter referred to.
A designates a cylindrical casing, one head a of which is bolted or otherwise
detachably secured thereto. Within this casing is fixed a plate B, on the face of
which is formed an appropriate camway b. Through the center of the head a
extends a shaft to which motion is imparted from a suitable source of power.
To the inner end of the shaft is affixed a wheel C, which is provided with a radial
guideway c therein for the reception of a reciprocative block D, the latter being
maintained in the recess by means of a plate c', that is secured on the face of the
wheel. In this plate is a radial slot c³, through which extends a projection on the

page_text: confined block. On this projection is mounted a freely-rotatable roller d, that is
fitted to the camway in the plate B, so that during the continuous rotation of the
wheel C through the power-driven shaft the roller d, being radially reciprocative,
will traverse the camway. The projecting portion of the block is connected by
means of a rod or link d' with an exteriorly-mounted cross-head d, which is guided
in suitable ways d³, and the traverse-bar E is connected with the cross-head, to the
end that said bar, during the travel of the roller in the camway, will be longitudinally
reciprocated.
By constructing the camway of an elliptic contour, substantially as illustrated in
Fig. 1, and by effectually guiding the roller in its radial movement, as described, a
steady uninterrupted movement is imparted to the traverse-bar. In this figure the
traverse-bar is represented as that of a winding or spooling machine, wherein aro
indicated the yarn-guide F, the cop-holding frame G, and the continuously-driven
drum H, by contact with the periphery of which the cop or spool is revolved.
In Fig. 4 is shown a modification of the invention in which the cross-head d' is
fitted to longitudinal guides on the cam-plate, and is rigidly connected with the
traverse-bar by a rod d. In this construction the cross-head is elotted transversely
in respect to its line of movement, and the projection of the reciprocative block in
the wheel C is fitted to the slot in said head, in consequence of which the head,
during the traverse of the roller, in the camway, is reciprocated longitudinally
similarly to the construction first above described."
Having now particularly described and ascertained the nature of the Baid
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:—
1. The combination of a casing provided with a detachable head, a positively-
rotated shaft extended through said head, a wheel or disk on the inner end portion
of said shaft and having a radial guideway, a block fitted to reciprocate in said
guideway and having a projection, the slotted plate through whose slot said
projection extende, a roller mounted on said projection, a fixed cam-plate whose
camway is engaged by said roller, a cross-head and a connection between said head
and the projecting portion of said block, together with cop-winding mechanism
connected to and operated by said head, substantially as described.
2. In combination, a casing provided with a detachable head, a positively-
rotated shaft extending through the same, a wheel carried by said shaft within the
casing and having a radial guideway therein, a block fitted to reciprocate in said
guideway, a plate which confines the said block in said guideway, and in which is a
slot through which extends a projection of the said block, a roller mounted on said
projection, a fixed cam-plate in said casing and having its camway engaged by the
said roller, a cross-head, a connection between the said head and the projecting
portion of said block, and a bar attached to the said cross-head, substantially as
described.
