Seeled the 25th January 1978 and dated the 23rd October 1877'
PROVISIONAL SPECIFICATION left by the said Thomas Wrigley at the Office
of the Commissioners of Patents on the 23rd October 1877.'

FOR DRIVING THE SAME."
The spindle is received into a tubular socket closed at the bottom end, so as to
retain oil. There is a bearing for the spindle in the upper part of the socket, and
also in the lower part. These bearings are preferably in one piece, formed as a tube
that is grooved on the outside to allow the passage of oil from the cup at the top of
the socket, and perforated at different points in its length to allow the oil to pass
freely to the spindle.
The spindle is revolved by a friction wheel acting against a pinion upon the.
spindle, such pinion having either a conoidal or concave surface for contact with the
driving wheel. The surfaces are kept in contact by the action of a spring.
. It is preferable to allow the spindle to slide endwise in the tubular bearing, and
apply the spring at the lower end to draw the spindle downwardly; but the:
spindle and socket may be at the end of a spring arm, so as to press the surfaces of
the friction wheel and pinion into contact.
It will be evident that this socket and tubular bearing allows the spindle to run
in oil, and there is no opportunity for the oil to leak, or the spindle to heat or wear.
This feature might be used with spindles driven by belts....

"
The object of this Invention is to drive the spindles of spinning machines by
beveled frictional wheels and pinions in place of the belts and pulleys heretofore
made use of.
In some instances spindles have been driven by cylindrical fricton wheels and
pinions, but the device is complicated and unreliable.
In the Drawing,-
Fig. 1 is an elevation, partially in section, of the spindle frame, actuating shaft,
and frictional gearing; Fig. 2 is a plan of the same; Fig. 3 is an elevation of the
spindle and its tubular-bearing; and Fig. 4 is a plan of such tubular bearing.
In spinning machinery it is usual to have a longitudinal bar or frame, at the edge
of which is placed the row of vertical spindles in sockets.
In the Drawing, the bar or frame A represents this longitudinal support for the
row of vertical or nearly vertical spindles. I have however only shown one of such
spindles B, the other spindles and the devices for driving the same being merely
duplicates of the devices hereafter described; and while it is to be understood that
a row of spindles will usually be employed, and that all the spindles in that row
will receive motion from the one longitudinal driving shaft C that is parallel to the
frame or bar A. Still my improvement may be availed of in cases where only one
spindle is employed.
The spindle B is adapted to receive at its upper end the bobbin or spool of any
usual character, upon which the thread or yarn is to be wound, and the lower end
of the spindle enters a tubular socket e closed at the bottom, and containing oil or
other lubricating material. There is an upper and a lower bearing for the spindle
within this socket, and it is preferable to make these bearings in the form of a brass
tube & that is perforated with holes to allow the oil to pass to the spindle, and this
tubular bearing is reduced in diameter at c, or the socket e is enlarged near this
part to form an oil chamber, and there are one or more grooves or channels 1, 1, to
allow the oil to pass down into this channel. The tubular bearing d after being
entered into the socket e is retained in place by the set screw f, or other convenient
device.
Upon the spindle B is the friction pinion h, preferably made of leather, riveted to
a collar upon the spindle; but wood or other suitable material may be employed
for the friction pinion, and upon the shaft C is the friction wheel k that is in contact
with the pinion h, and rotates the same and the spindle. It is to be understood
that this shaft C is rotated by competent power, that it runs longitudinally of the
machine, that it is supported in suitable bearings in the frame, and that there is
upon said shaft a friction wheel for each spindle in the row.
In consequence of the arrangement of the parts, the spindles can be as close to-
gether as usual, as the frictional gearing does not occupy more space than the
pulleys and belts heretofore usually employed.
h
The surface of the frictional pinion requires to be pressed into contact with the
friction wheel k, and for this purpose a spring is made use of, and such may be of
any suitable character; for instance, the arm that extends from the longitudinal
frame A to the socket e may be a spring to move the socket and spindle bodily, and
press the surfaces of the friction gears together; or the spring o may be applied to
give end motion to the spindle within the socket e. If the pinion h is conical, as
shown in Fig. 1, the spring o will have to be applied to draw the spindle into the
socket. In this case it is preferable to employ a nuts at the lower end of the

page_text: spindle with washers, and the expansive spring o between the nut and the tubular
bearing d.
The washers above and below the spring o should be stationary, there being
a pin upon each that lap past each other, as shown in Figure 3, so that both washers
and spring remain together, and thereby relieve the ends of the spring from wear; or
the ends of the spring may be soldered or otherwise connected to the washers, or
one pin may be in the bearing. If the friction wheel k is made with a shell or rim k¹,
as seen in Fig. 5, then the spring o should be applied below the bottom bearing of
the spindle to press the spindle outwardly, and keep the frictional surfaces in
contact.
To ensure uniformity of action in the frictional gearing it is important that dust
and foreign substances be excluded, and for the safety of the attendants the gearing
is covered by a shield v that is movable to give access to the parts for oiling and
cleaning. This shield or cover is hinged at w, so as to be swung back, as
indicated by the dotted line. The top edge of this cover terminates about in line
with the spindles, and the stationary portion or table x is supported by the frame A,
and extends to the top edge of the cover v. There are notches or scollops in the
edges of the covers adjacent to the spindles.
What I claim as my Invention, and desire to secure by Letters Patent is,-.
First. The combination with the spindle of the friction pinion h, a friction wheel
k on the horizontal shaft C, and a spring to keep the frictional surfaces in contact,
substantially as set forth.
Second. A socket e closed at the bottom, in combination with the spindle, and a
bearing & surrounding the lower part of the spindle, having holes for the passage of
oil to the spindle, substantially as set forth.
Third. The combination of the spindle B, movable bearing d, and spring o,
with the socket e that is closed at the bottom, and adapted to receive oil, as set
forth.
Fourth. In combination with the spindle and the frictional pinion and wheel
thereof, the movable cover v, substantially as set forth.
Fifth. In combination with the spindles and the driving wheels thereof, a
movable cover hinged at its lower portion, and swinging at its upper edge towards
or from the spindles to give access to the sockets, substantially as specified.
Sixth. In combination with the socket and spindle, the beveled friction pinion
and wheel, and driving shaft, substantially as specified.
In witness whereof, I, the said Thomas Wrigley, have hereunto set my
hand and seal, this Third day of April, A.D. 1878.
