Improvements in Tension Regulators for Spinning Machine Spindle
Driving Bands.
I PATRICK LAWRENCE KENNEY, of Pittsfield, Berkshire County State of
Massachusetts United States of America, overseer of Spinning, 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
This invention relates to band tension regulators for spinning machines and consists
in a certain novel construction and combination of devices fully described hereinafter
in connection with the accompanying drawings and specifically pointed out in the
claims..
In the drawings
Fig. 1 is a plan view of a regulating device embodying my invention.
Fig. 2 is a transverse sectional view on the line x-x of Fig. 1.
Fig. 3 is a perspective view of the swinging arm with its attachments.
Fig. 4 is a similar view of one of the brackets and the casting to which it is attached.
Fig. 5 is a detail vertical sectional view of one of the idler pulleys.
Referring by letter to the drawings A designates the frame of the machine near
one side of which is mounted the cylinder or drum B and C C designate the spinning
spindles which are arranged near the opposite side of the frame and are provided with
the whirls D D of the ordinary or any improved construction.
EE designate brackets which are arranged near opposite ends of the frame and
are provided with vertical arms ee which are mounted in vertical brackets ff in the
castings which are secured to the side of, the frame opposite the cylinder or drum.
These castings are bolted to the sides of the frame and are provided with set screws f¹ƒ¹
which engage threaded apertures in the sides of the sockets and impinge against the
vertical arms of the brackets.
The brackets are also provided with downwardly inclined arms 6¹.
The swinging tension arm G is pivoted at one end to a collar H which is fitted to
one of the brackets E and bears at its free end on the other bracket. The vertical
bolt on which the said arm is mounted engages a threaded aperture in the .side of

page_text: the collar Hand bears at its inner end against the inclined arm of the bracket to
clamp the collar in the desired position thereon and the head of the said bolt bears on
an inverted conical washer k which fits into the similarly shaped eye K on the swinging
arm.
It will be evident that when the said bolt is tightened the washer is drawn down
into the eye on the end of the said arm thus taking up lost motion and forming a tight
joint. When the washer or the parts of the joint become worn, a second washer of
a similar shape may be added or the screw may be slightly shortened by filing off its
inner end or in any other suitable manner.

Idler pulleys I are attached to the swinging arm at suitable points around which the
hand I, which extends around the spindle-whirls and the cylinder or drum passes and
the said pulleys are mounted on vertical bolts m which engage threaded apertures in
the collars M.
These collars may
be arranged at any desired points of the swinging arm and they
are clamped in position when the bolts m are tightened.
The operation of the improved regulator will now be readily seen. The free end of
the swinging arm is caused by the inclined position of the arin on which it rests and
of that to which it is pivoted to swing away from the whirls and thereby tighten the
band but when the said band contracts the free end of the same is allowed to approach
the whirls and thereby relieve the strain.
An adjustable safety stop N is arranged on the inner end of the inclined arm on
which the free end of the swinging arm rests to limit the inward movement of the said
swinging arm and the said stop is provided with a set screw n to enable it to be
adjusted at the desired point. An adjustable weight O is mounted on the swinging
arin which may be moved toward or from the free end thereof thereby either increasing
or decreasing the tension of the band the said weight being also provided with a set
screw o.
From the foregoing description it will be seen that the pivoted end of the swinging
arm may be adjusted toward or from the cylinder or drum.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with the cylinder or drum, the whirls and the band passing
around the same, of the bracket provided with a supporting arm which inclines down-
wardly from the whirls and the swinging arm bearing at its free end on the said
supporting arm and provided with idler pulleys around which the band extends whereby
as the band slackens, the swinging arm slides along the supporting arm away from the
whirls, substantially as and for the purpose specified.
2. The combination with the cylinder or drum, the whirls and the band passing
around the same, of the brackets provided with downwardly inclined supporting arms ee
the removable collar fitting on one of the arms the swinging arm pivoted to the said
collar and bearing on the other supporting arm, and the idler whirls secured to the
swinging arm and having the band passing therearound, substantially as specified.
3. The combination with the cylinder the whirls and the band extending around
the same of the castings provided with sockets the brackets provided with vertical arms
mounted in the said sockets and having downwardly inclined arms e e¹ the swinging
arm provided at one end with a collar which fits one of the inclined arms e' and
bearing at its free end on the other inclined arm and the idler whirls adjustably secured
to the swinging arm substantially as specified.
4. The combination with the cylinder, the whirls and the band extending around
the same, of the brackets having arms, e¹ e' the collar H mounted on one of the arms,
the swinging arm bearing at one end on one of the arms e¹ and provided at the other
end with an eye K the adjusting bolt fitting in the same eye engaging a threaded
aperture in the side of the collar, the conical washer arranged between the head of the
bolt and the eye and the idler pulleys arranged on the swinging arm, substantially as
specified.

page_text: 5. The combination with the cylinder, the whirls and the band passing around the
same, of the bracket provided with a downwardly inclined arm e', the swinging arm
bearing at its free end on the said arni and provided with idler pulleys around which
the said band passes and the weight mounted on its swinging arm and provided with a
set screw to clamp it in the desired position, substantially as specified.
6. The combination with the cylinder, the whirls and the band passing around the
same, of the bracket provided with an inclined supporting arm, the swinging arm
bearing at its free end on the supporting arm, the adjustable collars M M arranged on
the arm and provided with the vertical bolts m which fit in threaded apertures in the
collars and bear against the arm and the idler pulleys mounted on the said bolts and
having the band passed therearound substantially as specified.
