1, WILLIAM TERRELL GARNETT, of Barkerend Mills, Bradford, in the County of
York, Spinner, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of guide pullies in such a manner,
that the angle or inclination of the pullies may be adjusted without disturbing the
pulley frames, and the elevation of the pullies regulated to suit the tension of the
belt; also to arrange the pulley bearings that they are always parallel to the pulley
gudgeons and afford means for storing a quantity of lubricant for lubricating the said
gudgeons.
I accomplish my object by forming for each guide pulley frame, two plates, the
top plate being prepared for securing to the ordinary beam bracket, by which the
guide pulley frames are suspended in the same manner as ordinary frames.
The top and bottom plates of each frame I connect together by pillars or distance
pieces, and place between each pair of pillars or distance pieces, a sliding cross-bar
recessed for the reception of the pulley bearing or journal, which rests on hollow
curved projections or trunnions, so that on adjustment of the pulley, each bearing
accommodates itself to the pulley gudgeon.
The interior of the hollow curved trunnions communicate with the portion of the
bearing where the pulley gudgeon revolves and are filled with spongy material which
absorbs or stores for a time the surplus lubricant poured thereon, by which the journals
are kept lubricated without constant attention.
Through each bottom plate I pass regulating screws, each of which supports a
sliding cross-bar, between which, and the respective first named cross-bars, I place
springs which are compressed by the tightness of the belt, so that as the tension of
the belt reduces, the springs in each frame expand, thereby keeping the belt better in
contact with the pullies, and minimising the frequent shortening of the belt and the
danger of putting the same on to the pulley after joining.
By the introduction of the screws in the manner described, on setting the pulley
frames somewhat near the angle at which the pullies are required to run, either pulley

page_text: can be adjusted to the requisite angle, by turning one of the screws passing through
the bottom plate; so that the belt while running, can be brought to run in the centre
of the pulley without loosing and adjusting the frame and altering the line of contact
between the pulley gudgeons and bearings; and when the belt becomes too slack for
the springs to compensate for the stretching of the belt, it may be tightened without
taking it off, by turning the screws equally, by which the sliding cross-bars are moved
away from the driver or driven pulley as the case may be, thereby bringing the belt
to its proper tension without having to stop the machine to take it off and shorten.

page_text: I, WILLIAM TERRELL GARNETT of Barkerend Mills, Bradford, in the County of
York, Spinner do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particulary described and ascertained in and by the
following statement
My invention relates to certain improvements in guide pullies for regulating the
tension of driving belts, and has for its object, the construction of guide pulley
hangers in such a manner that the angle or inclination of the pullies may be adjusted
without disturbing the pulley frames or hangers, and the elevation of the pullies
regulated to suit the tension of the belt: also to arrange the pulley bearings that
they are always parallel to the pulley gudgeons and afford means for storing a quantity
of lubricant for lubricating the gudgeons.
In the accompanying drawings, Fig. 1 represents a front elevation of my improved
guide pulley hanger constructed with one pulley above the other. Fig. 2 is a front
view of my improved hanger as constructed when a pair of pullies are placed side
by side. Fig. 3 a side view of same. Figs. 4 and 5 are details of the bearings,
showing the trunnions and lubricant cells.
For each guide pulley frame I form two plates A and A', the top plate A being
prepared for securing to the ordinary beam bracket by which the guide pulley frames
are suspended in the same manner as ordinary frames. I connect the top and bottom
plate A and A' together by pillars or distance pieces B, and place between each pair
of pillars or distance pieces B, a sliding bar C recessed for the reception of the pulley
bearings or journals D, which rest on hollow curved projections or trunnions J, so that
on the adjustment of the pulley F, cach bearing D accomodates itself to the pulley
gudgeon G.
The interior or hollow portion of the hollow curved trunnions J, communicates with
the portion of the bearing D where the pulley gudgeons G revolve, and the said
hollow portions are filled with spongy material which absorbs or stores for a time
the surplus lubricant poured therein, by which the bearing or journals D are kept
lubricated without constant attention.
Through each bottom plate A', I pass a regulating screw K, each of which supports
a sliding cross bar L, between which and the first named cross bar (respectively, I
place springs M which are compressed by the tightness of the belt so that as the
tension of the belt reduces, the springs M in each frame expand, thereby keeping the
belt better in contact with the driving and driven pullies, thus minimising the frequent
shortening of the belt, and the danger of putting the same on to the pullies after
joining.
By the introduction of the screws K in the manner described, on setting the pulley
frame somewhat near the angle at which the pullies F are required to run when a
pair are placed side by side, either pulley F can be adjusted while the belt is running
to the requisite angle, so that the belt will run in the centre of the pulley F. by

page_text: turning one of the screws K, without altering the line of contact between the pulley
gudgeons G and bearings D and when the belt becomes too slack for the springs M
to compensate for the stretching of the belt it may be tightened without taking it off
by turning the screws K equally, by which the sliding cross bars Care moved away
from the driving or driven pulley as the case may be, thereby bringing the belt to its
proper tension without having to stop the machine to take it off and shorten.
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 :-
1. The combination of the pulley journals or bearings D with the sliding bars Ċ
and Land the screws K for the purpose set forth.
2. The combination of the sliding bars Cand L with the springs M and screws K
substantially in the manner and for the purpose set forth.
3. The pulley bearings D with trunnions J combined with the sliding bars C
springs M and screws K substantially in the manner and for the purpose set forth.
