PROVISIONAL SPECIFICATION.
An Improved Shaper Rail for Self Acting Mules and Twiners.
We, BENJAMIN ALFRED DOBSON, Engineer, ROBERT HARDMAN, Foreman
Mechanic, both of Bolton, in the County of Lancaster, and JOHN SMITH, Mule
Overlooker, of Patricroft, in the said County, do hereby declare the nature of this
invention to be as follows:-
:-
Our invention relates to an improved shaper rail for self acting mules, and
twiners, and the object of our invention is to make it practical and easy to change
the shape of the chase of the cop according to requirements.
We achieve this object by inaking that portion of the shaper rail which forms
the nose part of the cop as a loose incline similar to that at the other end of the
shaper, and we prefer to pivot this loose incline about the middle of the shaper
rail. At the other end of this incliue we employ an adjusting screw which enables
us to raise or lower the extreme end of the incline.
We can by this means make the chase of the cop either hollow, straight or
round.
We can also achieve our object by having a portion of the shaper rail cut out,
and fitting pieces of suitable shape on to this portion which will alter the incline of
the shaper rail.
We can dispense with a screw for regulating the pivoted incline and allow it to
be actuated by an incline in somewhat the same way as the incline at the other end
of the shaper rail; thus we can vary the shape of the chase of the cop from the
beginning to the end of the building exactly as we desire.
Dated this 25th day of November 1891.

COMPLETE SPECIFICATION.
An Improved Shaper Rail for Self Acting Mules and Twiners.
We, BENJAMIN ALFRED DOBSON, Engineer, ROBERT HARDMAN, Foreman
Mechanic, both of Bolton in the County of Lancaster, and JoHN SMITH, Mule
Overlooker, of Patricroft, in the said County, 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 :-
Our invention relates to an improved shaper rail for self acting mules, and
twiners, and the object of our invention is to make it practical and easy to change
the shape of the chase of the cop according to requirements.
At
We achieve this object by making that portion of the shaper rail which forms the
nose part of the cop as a loose incline similar to that at the other end of the shaper,
and we prefer to pivot this loose incline about the middle of the shaper rail.
the other end of this incline we employ an adjusting screw which enables us to raise
or lower the extreme end of the incline.
We can by this means make the chase of the cop either hollow, straight, or
round.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a front elevation of the two ends of a shaper rail made according to our
invention the middle portion being removed.

page_text: Fig. 2 is also a front elevation of part of a shaper rail showing our improvements
on a larger scale and
Figs. A, B and C represent three forms of cop noses all of which can be produced
by the use of a single shaper rail constructed according to our invention.
In the drawings, a represents a shaper rail made with a loose plate b hinged near
the front end of the shaper rail ate the rail being supported on the front and back
studs or bowls de which rest upon the copping plates fg respectively while the free
end of the pivoted plate rests upon an inclined copping plate h, all these parts
being of the usual' or other convenient construction.
4. f
In order to render it practicable and easy to change the shape of the chase of
the cop we make that portion of the shaper rail which forms the nose, of a loose
inclined piece i and pivot the same at to the shaper raila; at the other. end of
this inclined piece is an. adjusting screw & which is screwed through a portion of
the rail aand is locked by a nut 1.the under surface of the inclined piece resting
upon the point of the screw k." The. bowl p which actuates the copping faller is.
shown on the incline i near the front of the shaper rail.
In Fig. 2 the inclined piece is shown in full lines in one position, and indicated
by dotted lines in two higher positions; when the incline is raised to the highest
position by adjusting the screw which supports it the nose of the cop would be
formed round or full as shown in Fig. A; but to form the nose of the cop with
straight sides as in Fig. B the incline would be lowered by turning the screw to
the position indicated by the next dotted line and to form the nose of the cop
hollow as in Fig. C the incline would need to be lowered again to the position
shown by full lines in Fig. 2.
When the pivoted rail is raised or lowered by the setting screw as above
described the raila at the other. end should be correspondingly regulated by the
setting screw whereby the same length of chase is kept throughout.
q
1. We can also achieve our object by having a portion of the shaper rail cut out,
and fitting pieces of suitable shape on to this portion which will alter the incline
of the shaper rail.
We can dispense with a screw for regulating the pivoted' incline and allow it to
be actuated by an incline in somewhat the same way as the incline at the other end
of the shaper rail.
By either of the arrangements above described we can vary the shape of the
chase of the cop from the beginning to the end of the building exactly as we
desire. "'
...
Having now, particularly described, and ascertained the nature of our said
invention and in what manner the same, is to be performed we declare that what
we claim is
"
The arrangement use" and application of an adjustable loose piece or pieces
pivoted or otherwise fitted to a shaper rail whereby the chase of the cop may be
wound either round, straight; or hollow according to the position of the loose piece
substantially as herein set forth.
