I JOSHUA VALENTINE EVES of Brooklands, Knock County Down, Ireland Mill
Manager do hereby declare the nature of my invention for IMPROVEMENTS IN
WET SPINNING FRAMES to be as follows:-
These improvements consist of novel and simple arrangements for guiding or
controlling the direction of the pressure upon the pressing rollers of wet spinning
frames, the object being to make it practicable to apply the pressure to any
desired part of the saddle which connects the bearings on the pressing rollers that
are in contact with the retaining and drawing rollers and at same time that the
pressure can be guided or controlled in the required direction which is by
preference at right angles or nearly so to the contact faces of the drawing and
retaining rollers.
+
This object is accomplished by forming a joint or joints in the connections
between the saddles and the weight levers, the position of the joints being
adjustable so that the strain of the weight levers is diverted or guided in the
required direction. To adjust the position of the joints in the connections between
the saddles and the weight levers radius arms or levers are employed to which the
joints on the connections are attached or allowed to rest upon, the centres or pivots
of the radius arms can be raised or lowered or the distance from the pivots or
centres of the radius arms to the points of attachment can be varied so as to raise
or lower the points of attachment of the connections and so secure the desired
direction of the pressure wherever the pressure may be applied to the saddles
between the pressing rollers.
The direction of the pressure may also be controlled without any diversion
thereof by raising or lowering the fulcrums that carry the weight levers which
instead of being fixtures as at present are mounted on levers or slides controlled
by screws so that the levers may be readily raised or lowered to obtain the desired
direction of pressure on the saddles of the pressing rollers.
By these means the amount of pressure applied to the retaining and drawing
roller pressings can be distributed in any desired proportion and the reach or
distance between the drawing and retaining roliers be altered and yet the
proportion and direction of pressure can be maintained which cannot be done with
the ordinary arrangement and therefore an excessive pressure may have to be put
upon the drawing rollers to secure sufficient pressure upon the retaining rollers,
thus increased friction and wear is entailed which it is one of the purposes of this
invention to obviate.

I JOSHUA VALENTINE EVES, of Knock, County Down, Ireland, Mill Manager
do hereby declare the nature of my invention for "IMPROVEMENTS IN WET
SPINNING FRAMES," and in what manner the same is to be performed, to be
particularly described. and ascertained in and by the following statement:-
These improvements consist of novel and simple arrangements for guiding or
controlling the direction of the pressure upon the pressing rollers of wet spinning
frames, the object being to make it practicable to apply the pressure to any
desired part of the saddle which connects the bearings on the pressure rollers that
are in contact with the retaining and drawing rollers, and at same time to control
the pressure, or guide it in the required direction, which is, by preference, at right
angles to the plane of contact of the drawing and retaining rollers.
The manner in which this object is accomplished will be understood by reference
to the drawing herewith, in which the same letters and figures of reference always
apply to the same or like parts.
Fig. 1 is a sectional elevation of so much of a wet spinning frame as will serve
to explain the application of my invention thereto; and
Figs. 2, 3, and. 4 are detached views of modifications of the means which I
employ in carrying out my invention.-A. A¹. are the retaining and drawing
pressing rollers. B is one of the series of saddles used for retaining these rollers
in place and imparting pressure thereto. C is one of a series of weighted levers,
and D a divided rod for connecting the saddle with its weighted lever. The parts
composing this divided rod are connected together by a joint or joints d, the
position of which is adjustable vertically for the purpose of diverting the strain
of the weighted lever in the required direction. To adjust the position of the
joint of the compound rod D, a radius rod E is employed. This rod rests in the
fork of a bracket arm F; it is formed with a collar e, and screwed at its upper end,
as at e¹, to enter a screwed socket in the joint piece d. Situate below the collar e
is a washer e², formed with a V edge, which bears upon the forked bracket, to
provide for the slight tipping of the radius rod, when turned, to effect the
adjustment of the pressure on the saddle by the raising or lowering of the joint
piece d. In place of using screwed radius rods for adjusting the direction of the
pressure on the saddles, I may employ the arrangement shewn at Fig. 2, in which
the centres or pivots of the radius rods can be raised or lowered. In this example,
the radius rod E is pivotted at its upper end to the joint piece d, and at its lower
end to a pivotted arm E¹, which is made adjustable, it being connected to the
rail F by a screw E³ pendent therefrom. By either of the above described means,
the désired direction of pressure upon the saddle is secured, wherever the point of
pressure upon the saddle may be.
'
The direction of the pressure may also be controlled, without any diversion
thereof, by raising or lowering the fulcrum of the weighted levers C.
An arrangement of this kind is shewn at Figs. 3 and 4.-In Figs. 3, the weighted
lever C has its fulcrum on a bell crank lever C, which is fulcrummed on a bracket
of the rail F.-The shorter arm of this bell crank lever C¹ is formed with a

page_text: threaded socket to receive a screwed rod C2, which connects it rigidly, but
adjustably, with the rail F, the screw for that purpose passing through a threaded
socket of the rail.
Fig. 4 shews the weighted lever fulcrummed on a vertically adjustable slide G.
This slide is recessed to receive a projection from a bracket of the rail F.-A screwed
rod G¹, mounted in the slide G, passes through a threaded hole in this projection,
and serves to impart an up and down motion to the slide: Keyed to the lower
end of this screwed rod, is a bevel pinion, into which gears a pinion keyed to a
detachable handle bar G³, the end of which is journalled to rest in a bearing
provided for it on the slide. By turning this handle bar, rotary motion is
imparted to the screw G', which, being secured to the slide, but so as to turn
freely therein, will raise and lower the slide as desired, thereby lifting or lowering
the fulcrum of the weighted lever.
It will now be understood that by either of the above described means, the
levers C may be readily raised or lowered to obtain the desired direction .of
pressure on the saddles of the pressing rollers A A¹, and the amount of pressure
applied to the retaining presser rollers and drawing presser rollers A¹ can be
distributed in any desired proportion.-The reach or distance between the drawing.
and retaining rollers may also be altered without affecting the relative proportions
and direction of the applied pressure, whereas, with the ordinary arrangement, an
excessive pressure has to be put upon the drawing rollers to secure sufficient
pressure upon the retaining rollers. Thus, increased friction and wear is entailed,
which it is one of the purposes of this invention to obviate.
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
The means described with reference to the drawing, for regulating the direction
of the pressure applied to drawing and retaining rollers of wet spinning frames.
