We, JOSEPH HIRST, JOHN HIRST, and ALFRED HIRST, trading as B. Hirst & Sons,
Britannia Works, Halifax, Yorkshire, Wringing Machine Makers, do hereby declare
the nature of this invention to be as follows:-
The object of our invention is to reduce the friction on the shafts of wringing,
mangling, lawn mowing, and other machines and our improvements consist in the
employment of two discs made with a central hole surrounded by a series of crescent
shaped holes. These discs are placed edgwise and the crescent shaped holes receive
rollers, and whilst the holes allow a portion of the circumference of the rollers to-pro-
trude, yet the holes are two small to prevent the rollers dropping out. These discs
and rollers are placed into a box and made secure therein by an end plate. The shaft
of the rollers is then placed into the central hole of the disc, so as to rest upon and
touch the series of rollers supported by the discs, consequently as the shaft revolves,
the series of rollers revolves with it, so as to reduce friction to a minimum. The rollers
we employ are made without axles, and can be easily made as they only require to be
cut off a bar of metal of equal diameter.
Instead of the crescent shaped holes being made in connection with a hole within a
disc, the crescent shaped holes may be made on the periphery, and the rollers placed
therein.

We, JOSEPH HIRST, JOHN HIRST, and ALFRED HIRST, trading as B. Hirst and Sons,
Britannia Works, Halifax, Yorkshire, Wringing Machine Makers, 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 :-
:-
The object of our invention is to reduce the friction on the shafts of wringing,
mangling, lawn mowing, and other machines; and our improvements consist in the
employment of two discs made with a central hole surrounded by a series of crescent
shaped holes. These discs are placed edgewise, and the crescent shaped holes receive
rollers, and whilst the holes allow a portion of the circumference of the rollers to pro-
trude, yet the holes are too small to allow the rollers dropping out. These discs and
rollers are placed into a box and made secure therein by two end plates. The shaft of
the rollers is then placed into the central hole of the disc, so as to rest upon and touch
the series of rollers supported by the discs, consequently, as the shaft revolves, the
series of rollers revolves with it, so as to reduce, friction to a minimum. The rollers
we employ are made without axles, and can be easily made, as they only require to be
cut. off a bar of steel of equal diameter.
Such being the nature and object of our invention, we will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheet of drawings, wherein Fig. 1 is an end view of an arrangement of rollers and the
means of supporting them, constructed according to our invention, and Fig. 2 edge
view thereof. The apparatus comprises a box a having two plates b and c, secured
together by rivets or screws d. Within the box are dished or concave discs e and f
made with a central hole y and semicircular holes h, as shewn in detail Fig. 4. Two
of these discs are placed in the said box, with antifriction rollers i, which must be
introduced end wise into the semicircular hole before the plates and care put
together. Therefore, when the antifriction rollers are placed in position and the end
plates on the box made, secure, the surface of the rollers protrude through the semi-
circular, holes, as shewn in Figs. 1 and 3, where the latter is elevation of the parts
with one of the plates removed. On a shaft A being placed as shewn in the drawings,
and made to revolve by any form of mechanism, the rollers will also revolve, thereby
reducing the friction to the least-possible-degree.
Instead of employing discs as shewn at Fig. 4, we may employ discs as shewn at
Fig. 5, which is made with lugs j between two of which we place a roller i for holding
them in position.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
Firstly. The employment of discs having crescent shaped holes or lugs as shewn in
Figs. 4 and 5, for supporting rollers, arranged in manner substantially as shewn and
described.
Secondly. The employment of discs, having crescent shaped holes, or lugs, placed
within a box in manner substantially as shown and described.
