I, THOMAS GARE of 25 Booth Street, Edgeley, Stockport in the County of Cheshire,
Boot and Shoe Manufacturer, do hereby declare the nature of this invention to be
as follows:
This invention relates to improvements in bushes and bearings employed for holding
shafts or spindles revolving in a vertical or other position, and has for its object to
produce a bush, which in one piece, can be contracted cylindrically in the bearing
when pressure is exerted thereon, and which will expand when released therefrom, so
as to compensate for the interior wear of the bush and to ensure always a proper fit,
besides serving to contain a large amount of lubricant, which supplies itself gradually,
uniformly to the interior of the bush.
To accomplish this I suitably wind or coil a metal bar, preferably of flat section,
to form a hollow cylindrical body of suitable length and diameter.
This hollow cylindrical body or bush I fit loosely into the hearing, which as usual,
is formed with a cap, in such a manner that when pressure is exerted onto the
bush, it will be prevented from moving in a lateral direction and will contract
cylindrically.
On the sides of the bush, cavities are formed which serve as receptacles for the
lubricant, from whence it supplies itself to the interior of the bush by passing between
the coils of the same.
The coils of the bush may be wound more or less apart from each other & the
spaces thus formed filled up with plumbago or other lubricant in a consistent
state.

I, THOMAS GARE of 25 Booth Street Edgeley, Stockport in the County of
Cheshire, Boot and Shoe Manufacturer 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 improvements in bushes and bearings employed for holding
shafts or spindles revolving in a vertical or other position, and has for its object to
produce a bush, which in one piece can he contracted cylindrically in the bearing
when pressure is exerted thereon, and which will expand when released therefrom, so
as to compensate for the interior wear of the bush, and to ensure always a proper fit,
besides serving to contain a large amount of lubricant, which supplies itself gradually
& uniformly to the interior of the bush.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a sectional end view, Fig. 2 a longitudinal section of the bush and
bearing, Fig. 3 an end view, and Fig. 4 a side view of the bush only.
In carrying out my invention and referring to the figures generally, I suitably wind
or coil a metal bar, preferably of flat section, to form a hollow cylindrical body a of
suitable length and diameter.
This hollow cylindrical body a which forms a bush, I fit loosely into the bearing b
which as usual, is formed with a cap 64, in such a manner that when pressure is exerted
onto the bush a by means of the bolts c, and cap 61, it will be prevented from revolving,
and will contract cylindrically so as to permit of compensating for the wear that takes
place from time to time, the bush a being held in position longitudinally by means of
the flanges & formed on each end of the bearing and cap & D.
In order to ensure a proper fit of the bush a when new without applying pressure
thereon, make the interior diameter a little less than the diameter of the shaft e to
which it will be applied.
On the sides of the bush a one or more cavities & are formed in the bearing b, b,
which serve as receptacles for the lubricant, from whence it supplies itself to the interior
of the bush a by passing between the coils of the same.
The coils of the bush may be wound more or less apart from each other and the
spaces thus formed filled up with plumbago or other lubricant in a consistent
state.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is:-
1st. In bushes and bearings, the employment of a bush a formed of a metal bar
coiled cylindrically, as set forth.
2nd. The combination of a bush constructed as specified in the preceding claim,
with a bearing & b', the bore of which is formed with cavities d', and flanges, d and
can be varied in diameter for the purpose of causing the bush a to contract, substan-
tially as set forth.
