Improvements relating to the Top Rollers of Mules and Ring and

I HENRY PALMER of. No. 296 Lees Road Oldham in the County of Lancaster,
Engineer do hereby declare the nature of this Invention to be as follows:-
My said Invention has reference to the top 'rollers of mules and ring and other
spinning frames and relates particularly to means for relieving the said top rollers of
the weight which usually holds them down upon the lower fluted rollers at the times
when the machine is at rest. Among spinners it is well known that the top rollers
which are usually covered with leather or cloth become indented and rapidly deteriorated
by being pressed down upon the fluted rollers when the machine is at rest. My
invention relates to means for obviating this disadvantage by relieving the top rollers
of the weight when the machine is at a stand. Under ordinary circumstances the
presser saddles of the top rollers are held down by rods or links which are adjustably
connected to weighted levers or the said presser saddles are directly weighted. I
provide means whereby the said weighted levers or weights can be raised when
desired so as to relieve the rods or links froin the downward pull of the weights.
Beneath the said weighted levers or weights I arrange a bar which extends from end
to end of the frame or throughout a section of the frame or mule. The said bar can
be raised and lowered by means of a lever or levers which is or are arranged at the
ends or at other points in the length of the frame or machine. The said levers are
each provided with a convenient catch for retaining the lever when it has been moved
into the position for raising the lifting bar and weighted levers or weights and the
said catch is easily released in grasping the lever to return it to its normal position
when the lifting bar is again lowered so as to hang the weights again upon the axes
of the top rollers. Instead of the pivotted lever and catch for raising the lifting bar
I might use a cam or excentric or cams or excentrics or I might dispense with the
lifting bar and use a series of such cams to act directly on the weighted levers or
weights or I might employ a continuous cam or excentric lifter extending throughout

page_text: the length of the frame. By the provision of such easily operated and convenient
means the attendants can easily relieve the top rollers of the weight at the times
when the machinery is stopped for example at meal times and during the night. I
thus prevent the top rollers from becoming marked and indented and in addition to
the economy thus secured the quality of the yarn is also appreciably improved.

COMPLETE SPECIFICATION.
Improvements relating to the Top Rollers of Mules and Ring and
other Spinning Machines.
I HENRY PALMER of No. 296 Lees Road Oldham in the County of Lancaster,
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 and accompanying drawings
―
My said Invention has reference to the top rollers of mules and ring and other
spinning frames and relates particularly to means for relieving the said top rollers of
the weight which usually holds them down upon the lower fluted rollers at the times
when the machine is at rest. Among spinners it is well known that the top rollers
which are usually covered with leather or cloth become indented and rapidly deteriorated
by being pressed down upon the fluted rollers when the machine is at rest. My
Invention relates to means for obviating this disadvantage by relieving the top rollers
of the weight when the machine is at. a stand. Under ordinary circumstances the
presser saddles of the top rollers are held down by rods or links which are adjustably
connected to weighted levers or the said presser saddles are directly weighted.
provide means whereby the said weighted levers or weights can be raised when desired
so as to relieve the rods or links from the downward pull of the weights.
And in order that my said invention may be properly understood I will now
proceed more particularly to describe the same with reference to the annexed sheet of
drawings.
Fig. 1 of the said drawings is a section of that portion of a spinning machine which
supports the brackets carrying the drawing rollers:
The said drawing rollers are shown in section and the lower rollers are marked a
while the top rollers are marked b. These top rollers are the covered rollers which
it is the object of my invention to relieve from pressure when they are not working.

page_text: The usual method of weighting these top rollers so as, to cause them to press upon
the lower rollers a is shown at Fig. 1. A link and hook c. d extends from the presser
saddles or bearings of the top rollers the hook d supporting the weighted lever e as
shown. The weight on the lever e may be adjusted according to the pressure
desired to be imparted to the top rollers. All of these parts are usual in spinning
frames. I will now proceed to describe my improved means for at times raising the
weighted levers e and thus relieving the top rollers from pressure. It will be under-
stood that a great number of the levers e exist in the length of the frame and my
lifting apparatus would most likely be placed at intervals throughout the frame so as
to lift a certain number of the levers e at a time. Beneath the levers e I place a barg
which is so arranged that when it is dropped to its lower position as in Fig. 2 it is
quite clear of the levers e while in its raised position as in Fig. 1 it slightly lifts the
levers e and weights and thus relieves the top rollers. The means for raising and
lowering the bar g are as follows: Upon the front bar or stay h of the frame I bolt a
bracket which is formed with a tail extending to the rear as plainly seen in Fig. 1.
I pivot a bell crank lever j upon this bracket i by means of a stud k. The shorter
arms or jaw of the lever j carry a stirrup composed of two arms as more clearly
shown in Fig. 3. and in which the bar g hangs suspended. The longer arm of the
lever j is cast or otherwise formed to present a ledge j as clearly shown in dotted
lines in Fig. 1, and is also cored out above so as to receive an arm m from a second
lever m which lever m is also formed at the foot as a hook to lay hold of the ledge j¹
on the lever j. The said second lever n is also formed as a catch to engage with the
rear of the tail of the bracket i. It will thus be seen that the foot of the lever m
acts as a clip to connect the lever ; to the tail ¹ of the bracket i: When the clip or
lever m is in the position shown in Fig. 1 the lever j has been pulled back in the
direction of the arrow until the clip m has dropped into engagement with the tail ¹ of
the bracket i. In thus pulling back the lever j it will be seen that the bar g is
at the same time lifted, raising the weighted levers e and relieving the top rollers from
pressure which is the object of my invention. When it is desired to replace the
weight on the top rollers I simply grasp the upper ends of the levers ; and m with one
hand and draw them together whereby the lever m is caused to turn on its hook pivot
raising the other end clear of the tail and allowing both levers to fall forward into
the position shown in Fig. 2. In this position the bar 9 has dropped clear of the
leverse the whole weight of which is thus again thrown upon the links and hooks C, d
and consequently upon the top rollers b. The described apparatus may be fixed to the
frame at suitable intervals so as to act upon a stated number of the weighted levers,
or one such apparatus might be fixed at each end of the frame so as to lift the whole
of the weighted levers in the frame between them.
Although I consider the apparatus described and shown to be the most useful and
effective for the purpose I do not limit myself thereto. For example I might use
cams or excentrics o to lift the bar g as indicated by the sketch Fig. 4 or such cams
or excentrics might act directly upon the levers e or an elongated cam or excentric
might extend along the frame and act on the weighted levers.
By the provision of such readily operated and convenient means the attendants can
easily relieve the top rollers of the weight at the times when the machinery is stopped,
for example at meal times and during the night. I thus prevent the top rollers from
becoming marked and indented and in addition to the economy thus secured the quality
of the yarn is also appreciably improved.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:―
(1) Relieving the top rollers of mules and ring and other spinning machinery at the
times when the machinery is at rest by the employment of a bar or bearer extending
beneath the weighted levers and capable of being raised so as to lift the said levers and
relieve the top rollers of weight and of being dropped so as to again weight the top
rollers substantially as described and shown."

(2) The apparatus for raising and lowering the said bar for relieving the top rollers
of weight, and consisting of a bell-crank lever and stirrup in which the bar is suspended
in combination with the clip lever for anchoring the said bell-crank lever to a fixed
abutment at the times when the weight levers and bar are raised and for releasing the
said bell crank lever when it is desired to again weight the top rollers substantially as
described and shown.
(3) The combination of the said lifting bar with the apparatus for raising the same
substantially as described and shown.
(4) As means for raising the said lifting bar or for lifting the said weighted levers
directly, the employment of excentrics or cams either in sets or in the form of a
continuous cam or excentric for acting on a number of the said weighted levers,
substantially as described and shown.
