Improvements in Slubbing Intermediate and Roving Frames
Employed in the Preparation of Fibrous Materials for
Spinning.
1, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Engineer, 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 :-
My invention relates to improvements in slubbing, intermediate and roving frames
employed in the preparation of fibrous materials for spinning, and my improve-
ments consist in a novel arrangement and combination of mechanism for moving
the lifter reversing bevel gears at each change in direction of travel of the lifting
rail.
In the accompanying two sheets of drawings-
Figure 1 is a side sectional elevation, Fig. 2 a sectional plan and Fig. 3 an end
sectional elevation of part of a slubbing, intermediate or roving frame illustrating
the application of my improvements.
In these views, a designates the frame of the machine, b the upright shaft which
drives the jack-in-box or differential motion (not shown); b' is the bevel pinion
on the upright shaft, c d are the lifter reversing bevel wheels which are fixed on
the sliding shaft e and gear alternately with the bevel on the upright shaft.
Fixed adjustably on the sliding shaft e is a grooved collar e' the groove of which
is engaged by the forked end of a bracket f' fixed adjustably on the reversing
rod on which are also mounted two fixed collars g g¹ and two sliding collars h h
(or it might be a single grooved sleeve); between each pair of fixed and sliding
collars is a coiled spring i or respectively, and these springs are alternately
compressed by the action of an elbow lever j which is fulcrumed at j₁ to the
frame a.
One end of this lever j is forked and engages the reversing rod f between
the two sliding collars h h and the other end enters a specially shaped slot k¹ in
a bracket forming part of the reciprocating rack k which is driven by the spur
wheel on the lifter shaft and so actuates the bobbin lifting rail. It will thus
be understood that as the rack k rises and falls the shape of the slot causes the
elbow lever to be moved backward and forward on its fulcrum j¹ thereby actuating
the sliding collars and alternately charging first one and then the other of the
springs. The reversing rod f is connected at m' by an arm or extension m to
a swivel lever n which is fulcrumed at n' to the frame a. The upper end of the.
swivel lever n has a projection 2 on it which is latched alternately by the building
motion catches o o' which are mounted and actuated in the usual way well under-
stood.
In the drawing are also shown the rack wheel or ratchet wheel the change
motion ratchet levers 9 9', the rocking cradle r the screws 3s for releasing the
catches o respectively, the anchor bar or diminishing rod t and the double
slide u which is fixed to the bobbin lifting rail and so rises and falls with it.
In Figs. 1 and 2 the lifter reversing bevel c is shown in gear with the bevel 6',
the elbow lever j is shown at the bottom of the slot k whereby the sliding
collar has been moved to compress the spring i between it and the fixed collar g
and the reversing rod f is latched by the catch o. When the next change takes
place the cradle r rocks and by the screw s knocks the catch o off the
projection n² so releasing the reversing rod f; the spring i then immediately opens
and forces the reversing rod f in the direction of the arrow, thereby taking the

page_text: lifter reversing bevel c out of gear and putting the bevel d into gear with the
bevel 6 on the upright shaft b. Before the next change takes place the spring ¹
will have been charged by the movement of the slot k on the rack k actuating the
lever so that when the catch o' is knocked off the reversing leverf will be moved
by the force of the spring in the opposite direction, that is to say, back into
the position indicated on the drawings with the reversing bevel c in gear and the
bevel d out of gear with the bevel b¹.
By this arrangement of coiled springs upon the reversing rod the anchor bar or
diminishing rod t is relieved of the stress and strain usually put upon it by having
to overcome the resistance of weights or springs connected directly to it.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The general combination and arrangement of parts for moving the reversing
rod and reversing the lifter bevel gears at each change substantially as and for the
purposes herein described with reference to the accompanying drawings.
2. The combination with the reversing rod and connected swivel lever n con-
trolled by the catches o o¹ of the building motion, of the coiled springs ii and
means such as the elbow lever ; and slot k¹ on the reciprocating rack k for
alternately charging said springs substantially in the manner and for the purposes
herein set forth.
Dated this 15th day of March 1895.
