Improvements in the Mountings of Rollers of Roving, Spinning,
and Twisting Frames.
I, EDMUND TWEEDALE of Globe Works Accrington in the County of Lancaster
Manager, do hereby declare the nature of this invention to be as follows:
The object of this my said invention is to ensure that the "nebs" which carry
the top rollers shall be all lineable and true to each other, so as to avoid the twist,
or uneven line in the rollers inseparable from the use of mountings as heretofore
constructed, also to provide improved means of securing the brackets which carry
the neb fingers on their shaft, and to prevent the nebs coming in contact with or
falling upon the rollers.
"
According to this my said invention, I employ an improved form, or section of
finger" for carrying the nebs, that is to say I employ fingers of three or five sided
figure on cross section the under part of the finger being of V form, the upper
surface being horizontal forming a flat nipping surface for end of a set screw.
The
hole through the neb, for reception of the improved section of finger is formed by
boring and by use of a slotting or other like machine, angular surfaces are formed
along the bore hole so that when the nebs are placed on the improved finger, they are
not twisted by the action of tightening their holding set screw, as is the case, when
square or round section of finger and set screw are employed.
The brackets for carrying the neb fingers, I secure on the bracket shaft by means
of a taper pin, there being formed across the shaft a semicircular recess or bed and a
transverse hole bored through the bracket, so as to intersect the shafts eye of the
bracket and forins along with taper pin and the recess in the shaft, a locking device
which not only secures the brackets firmly and truly on their carrying shaft and
prevents the nebs falling or bearing upon the rollers but also provides convenient
means of adjusting the brackets, and nebs to any required length of rollers because
the transverse recesses can be formed at any point or points of the length of tho
bracket shaft.

Improvements in the Mountings of Rollers of Roving, Spinning,
and Twisting Frames.
I EDMUND TWEEDALE of Globe Works, Accrington, in the County of Lancaster,
Manager, 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 an improvement in the mountings of the top rollers of
roving, spinning, and twisting frames, the object being to secure and preserve a
correct alignment of said rollers so as to prevent the twisting of same inseparable
from the mountings as at present constructed.
"
According to this my said invention 1 employ an improved form or section of
finger" which carries the "nebs" or bearing blocks of the top rollers, upon which
said blocks may be adjusted and secured without being twisted in the act of screwing
thom down, while to prevent the "nebs" or blocks themselves falling and bearing
upon the drawing rollers below; and to allow for their lateral adjustment I provide
suitable means for securing the brackets carrying the fingers upon the bracket shaft.
Such being the nature and object of my said invention the following is a complete
description of same reference being had to the accompanying drawings forming a
part of this specification in which :-
Fig. 1 shows, in elevation, a portion of a roving, spinning, or twisting frame with
the top roller mounted according to iny invention.
Fig. 2. is a left hand elevation of same.
Fig. 3. is a side view of bracket shaft, bracket, finger, and "nebs" upon an
enlarged scale.
Fig. 4. is an end view of Fig. 3.
Fig. 5. is an end view of one of the "nebs" detached.
The finger a I form five sided in cross section as shown, and arrange it in the
bracket so that one of the flat sides is on top and thus presents a surface for the
screw c which secures it in same. The lower portion of the hole in the bracket is
formed of a shape so that two sides of the finger may rest therein as shewn. The
holes through the "nebs" or bearing blocks dare similarly formed of a V shape
below. Holes of this shape may be formed by first boring them out round and then
slotting or filing the two angular faces therein. It will be evident that a three sided
or other angular figure in cross section will be equally good for the finger, all that is
wanted being angular faces for the V shaped part of the holes in the "nebs
and
brackets, and a flat face for the screws c in the brackets and the screws e of the
" nebs."
In this way the "nebs may be set in position to receive the top rollers
and the screws tightened up without fear of twisting them or forcing them out of
line with the opposite one which receives the other end of the roller, the journals of
which, it will be seen are simply dropped into the groove in each block so that the
top roller rests upon the drawing roller below.
"

page_text: To prevent the brackets & twisting on their shaft and possibly allowing the
"nebs" to fall into contact with the drawing rollers g, I form grooves h transversely
across the top face of the shaft as shewn in Fig. 4 and key the bracket into same by
means of a taper key i, thus holding the bracket and preventing it from turning,
while the recesses h at the same time allow of the brackets being shifted laterally
along the shaft and keyed in same when the top rollers & happen to be varied or differ
in length.
Having now particularly described and ascertained the nature and object of my
said invention and in what manner the same is to be performed I declare that
what claim is :-
แ
"
1. A bracket carrying an angular faced finger in combination with nebs or
bearing blocks having corresponding angular faced holes therein, to receive the finger,
and screws for adjusting them on the latter, so that the top rollers may be held in
line, substantially as described.
2. The combination with an angular faced finger, and "nebs" or bearing blocks
having corresponding angular holes therein, and means for securing same to said
finger, of a bracket secured to the shaft by a taper pin engaging with a groove in
the shaft and in the bracket, the said bracket having an angular faced hole, and
means for securing the finger in same, substantially as, and for the purposes
described.
