IMPROVEMENTS IN THE PENDENTS AND PENDENT PULLEYS OF SCUTCHERS AND OPENERS
Year: 1885

page_text: I LAYCOCK HARGREAVES, of Globe Works, Accrington, in the County of
Lancaster, Foreman Mechanic, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN THE PENDENTS AND PENDENT PULLEYS OF SCUTCHERS AND
OPENERS" to be as follows:-
"
Heretofore the antifriction bowls or runners employed between the " pendents
have been of little use because two pendents pressed on opposite sides of each
runner so that the runner was locked between the two, and could not revolve in
either direction-As a means of obviating the defect two runners having their
peripheries in contact has been suggested or used between each pair of pendents
but with the obvious defect of increasing the distance or space between the
pendents or else necessitating use of runners of small diameter.
The object of this my invention is to ensure rolling friction between pendents
and runners whilst maintaining usual spacing distance of the pendents.
According to this my said invention mount loosely upon an axis of a pin which
is free to run in the groove of the cross bar, three runners, the two outer ones being
somewhat larger in diameter, than the middle one. Three runners being between
each two pendents, and in the centre of each pendent on one side or face thereof is
a vertical rib of width slightly narrower than the width of the central and smaller
runner referred to so that when the pendents and runners are in position the plain
face or side of one pendent, bears upon the peripheries of the two larger runners
whilst the central rib, on its other face, bears only upon the periphery of the
central and smaller runner the larger runners are free to and revolve one,direction
the central and smaller runner revolves in the opposite direction and thus there is
secured rolling friction for all the pendents and runners without any alteration in
spacing of the several pendents.

I, LAYCOCK HARGREAVES of Globe Works, Accrington, in the County of
Lancaster, Foreman Mechanic do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE PENDENTS AND PENDENT PULLEYS OF SCUTCHERS AND
OPENERS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Heretofore the anti-friction bowls or runners employed between the "pendents"
have been of little use because two pendents pressed on opposite sides of each
runner so that the runner was locked between the two, and could not revolve in
either direction.
i
As a means of obviating the defect two runners having their peripheries in
contact has been suggested or used between each pair of pendents but with the
obvious defect of increasing the distance or space between the pendents, or else
necessitating use of runners of small diameter.
The object of this my invention is to ensure rolling friction between pendents
and runners, whilst maintaining usual spacing distance of the " 'pendents."
According to this my said invention, I mount loosely upon an axis of a pin which
is free to run in the groove of the cross bar three runners, the two outer ones being
somewhat larger in diameter than the middle one, three runners being between
each two pendents, and in the centre of each pendent on one side or face thereof is
a vertical rib of width slightly narrower than the width of the central and smaller
runner referred to, so that when the pendents and runners are in position the plain
face or side of one pendent bears upon the peripheries of the two larger runners,
whilst the central rib on its other face bears only upon the periphery of the central
and smaller runner, the larger runners are free to and revolve in one direction the
central and smaller runner revolves in the opposite direction, and thus there is
secured rolling friction for all the pendents and runners without any alteration or
loss in spacing the several pendents.
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,
Fig. 1 is front elevation of part of a set of pendents, runners, and rail constructed
according to my invention.
Fig. 2 is a sectional plan of Fig. 1.
Fig. 3 is a side elevation partly in section.
Fig. 4 is an enlarged sectional plan view of two pendents and the runners.
At 1 is a pin which is free to run in the groove 2 of the cross bar 3.
Three runners 4, 5, and 6, the two outer ones 4, 6, being somewhat larger in
diameter than the middle one 5. Three of such runners being between each two
pendents 7 and 8, and in the centre of each pendent on one side or face thereof is
a vertical rib 9 of width slightly narrower than, the width of the central and
smaller runner 5, so that when the pendents 7, 8, and runners 4, 5, and 6 are in
position, the plain face or side 10 of each one pendent bears upon the peripheries
of the two larger runners 4 and 6, whilst the central rib 9 on its other face bears

page_text: only upon the periphery of the central and smaller runner 5, the larger runners 4
and 6 are free to and revolve in one direction, the central and smaller runner 5
revolves in the opposite direction, and thus there is secured, rolling friction for all
the pendents and runners without any alteration or loss in spacing of the several
pendents.
It is obvious like results may be obtained by grooving one face of each pendent
and employing larger diameter pulley in centre (see Fig. 5) periphery of latter
pulley enters groove and bears against back of next pendent, whilst the smaller
and outer pulleys act on the outer portions of the pendent.
This arrangement being a mere transposition-but I prefer the construction first
herein described and illustrated.
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 ;
Firstly. The pendents having one side or face plain, the other side or face having
the central rib 9, such pendents being and operating in combination with the
varying diameter of the pulleys for purpose and as herein fully described and
illustrated by the annexed drawings.
Secondly. The use of the runners 4, 5, and 6 in combination with the grooved
pendents 7, 8, as illustrated by Fig. 5 and herein described.
