improved Means or Apparatus for Tightening or Releasing the Books
or Holders used in Silk Dressing Machines or Frames.
I, JOHN DANIA TOMLINSON, of Soho Works, Rochdale, Engineer, do hereby
declare the nature of this invention to be as follows:-
My said invention relates to improved means or apparatus for compressing or
tightening in a containing box or frame the books or holders which are used for
holding silk during its treatment in dressing machines or frames.
The compression or tightening is at present effected by tightening or pressing
screws which are 1otated by hand
The object of my said invention is to provide means for rotating such com-
pressing screws by power.
According to my said invention I provide in a suitable frame one or more
spindles shafts or mandi els corresponding to the number of screws to be operated
upon The said spindles shafts or mandrels are caused to rotate by belt or
toothed gearing or a combination of belt and toothed gearing Each spindle 18
provided with a clutch kept in gear or in action by springs weighted levers or
the like the pressure of which may be adjusted so that when the pressure to be
applied reaches a predetermined maximum the clutch will disengage itself or
slip
The head or outer end of each compressing sciew 18 so formed that when
presented to the free part of the clutch it engages therewith and if the spindle
is rotating the screw will be caused to rotate and to compress the books or holders
against which it bears.
In one form of my said invention one half of the clutch may be formed on the
head of the compressing sciew itself
When the resistance to the screw reaches any desired maximum the clutch
will disengage itself oi alıp whereupon the screw will cease to rotate.
To the main driving shaft of the apparatus I apply a control or reversing
clutch worked by a foot lever or other convenient means. By means of this
clutch the spindles or mandrels may be caused to rotate either to the right or to
the left for the purpose of screwing up or unscrewing the compressing screws as
may be desired
When the control clutch is in its mid or neutral position the
spindles or mandrels will be stationary
I provide guides or rails for enabling the frame carrying the books or holdera
to be brought up so that the compressing screws may engage, and also means
for holding the frame while the compressing action is taking place.
Dated this 23rd day of December 1898.

I, JOHN DANIA TOMLINSON, of Soho Works, Rochdale, Engineer, do hereby
declare the nature of this invention 'and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
-
My said invention relates to improved means or apparatus for compressing or
tightening in a containing box or frame the books or holders which are used for
holding silk during its treatment in dressing machines or frames
The compression or tightening 18 at present effected by tightening or pressing
screws which are rotated by hand
The object of my said invention is to provide means for rotating such com-
pressing screws by power
In order that my invention may be more clearly understood I will describe
the same with reference to the accompanying drawings in which
Fig. 1 is a front elevation,
Fig. 2 18 a plan,
Fig. 2 illustrates a detail to be hereafter described.
Fig. 3 illustrates in plan a foot lever to be hereinafter described.
According to my said invention I provide in a fiame a having strengthening
or supporting stays a¹ one or more spindles shafts or mandi els 6 corresponding
in their number and position to the screws to be operated upon Keyed on to
each of the said spindles shafts or mandrels is a tooth wheel c engaging with
worms secured to the main driving shaft e Each spindle is provided with
a clutch f kept in gear oi in action by springs 7 the pressure of which may be
regulated by the nuts gl so that when the pressure to be applied reaches a pre-
determined maximum the clutch f will disengage itself or slip In lieu of
springs I may use weighted pressure levers for keeping the clutches in engage-
ment. Mounted on the mam driving shaft e and keved thereto are fast and loose
pulleys and h¹
The main driving shaft e is duiven in either direction as
desired by driving_belts To determine the duection in which the main driving
shaft shall rotate I provide a reversing clutch 2 which is caused to engage with
either of the pulleya h h¹ as may be required
The head or outer end of each compressing screw (shown in dotted lines)
18 square or is otherwise so formed that when presented to the free part of the
clutch it engages therewith and if the spindle then rotates the screws will
be caused to rotate and to compress the books or holders against which it bears A
convenient way of readily effecting the engagement is by the use of two
pins on the part f¹ of the clutch These act in the same way as the pins
of a lathe carrier on a cross bar shown in front elevation in dotted lines in
Fig. 1 and Fig. 2 secured to the head of the compressing screw.
The part of the clutch rotates in a bearing or if desired the part f¹ of the
clutch may be formed on the head of the screw it is desired to rotate
The compressing screws are carried by the frame or holder of the dressing
machine which is presented to the above described apparatus when the screws
are operated. When the resistance of the compressing screws reaches any
desired maximum the clutch f will disengage itself or slip whereupon the free
part of the clutch will cease to rotate.
To the main diving shaft e of the apparatus I apply a control or reversing
clutch i worked by a lever & fulci umed at k¹ to the frame and having its upper

page_text: of the
to
end which may be formed as a fork engaging with the central part
reversing clutch. Hinged at to the said lever k 18 a link connected at
another link secured to the shaft / Connected to the said shaft is a foot
lever m constructed with left and right foot plates m³ m³ to enable the reversing
clutch when desired to be slid into engagement with the pulley h or h¹. By
means of this clutch the direction of rotation of the clutches f for the purpose
of screwing up or unscrewing the compressing screws may be governed. When
the reversing clutch is in its mid or neutral position (as shown) the spindles
or mandrels will be stationary In order to retain the reversing clutch in its
mid or neutral position when desired the foot lever m 18 provided with springs m³
secured to the bearing p
When in use guides or rails are provided for enabling the frame carrying the
books or holders to be brought up so that the compressing screws may engage
with the clutches Cramps or bolts may also be used for holding the book
carrying frame up against the clutches while the screws are being rotated.
In lieu of fast and loose pulleys operated by belts an electric motor controlled
by a reversing switch may be used.
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 19
-
1. The apparatus for operating the screws for compressing the books or holders
used in silk dressing machines substantially as described and shown.
2. An apparatus consisting of spindles and automatically engaging and disen-
gaging clutches provided with means for diving and for reversing their direc-
tion of rotation for operating the screws of the book holders of silk diessing
machines or frames substantially as set forth and shown
