IMPROVEMENTS IN VELOCIPEDE, AXLE OR OTHER BEARINGS
Year: 1885

page_text: We, THOMAS HILL, of Bridgeton, Glasgow, in the County of Lanark, North
Britain, Engineer, and "THE HOWE MACHINE COMPANY (Limited)," of Glasgow
aforesaid, Machine Manufacturers, do hereby declare the nature of our invention
for IMPROVEMENTS IN VELOCIPEDE, AXLE OR OTHER BEARINGS to be as follows:-
This Invention relates to a simple construction of the shells or cases of
Velocipede, axle or other bearings; and mode of connecting said bearings to the
forks or frames of Velocipedes, rendering them so as always to tend to keep the
alignment of the bearing surfaces of the bearings with respect to the axles true,
that is, self adjustable; and is applicable to Coned, Ball, Roller and other Cycle
bearings.
According to the Invention, the shell or case of the bearing is formed with two
pins projecting from its opposite sides, constituting trunnions. The trunnions are
turned and finished, and fitted into a semicircular or other shaped holder, so as to
be capable of turning therein; the bearing shell and holder thus being equivalent
to one half or part of a universal joint. The holder is rigidly connected to the
fork or frame, and the shell being free to turn therein from the centre, tends to
adjust itself relatively to the axle.

Britain, Engineer, and "THE HOWE MACHINE COMPANY (Limited)" of Glasgow
aforesaid, Machine Manufacturers do hereby declare the nature of our invention
for IMPROVEMENTS IN VELOCIPEDE, AXLE OR OTHER BEARINGS and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement reference being had to the accompanying Drawing
whereon similar reference letters indicate the same or similar parts in the different
Figures thereon :—
The said Invention relates to a simple construction of the shells or cases of
Velocipede, axle, and other bearings, and mode of connecting said bearings to the
forks or frames of Velocipedes, rendering them so as always to tend to keep the
alignment of the bearing surfaces of said bearings true, with respect to the axles or
shafts to which they are applied, viz. self-adjustable.
Figures 1 and 2 represent respectively a side and front or back elevation of a
ball bearing as specially constructed in accordance with this Invention for applying
to the ends of Bicycle hollow forks. The shell or casing a of the bearing is formed
with two round trunnions b which are turned up, finished and fitted into a semi-
circular bracket or holder c so as to be able to oscillate freely therein.
Figures 3 and 4 are respectively a side and front elevation of another modi-
fication of bracket or shell holder, consisting of a bracket g and two pins i fitted
therein. The pins i have round holes bored therein into which are fitted the
trunnions ; the pins i being then put into holes in the bracket g and fixed therein
by nuts m. The bracket g as represented in Figures 3 and 4, is formed with a
stem to fit into the end of a hollow fork o.
Figure 5 is a side elevation and Figure 6 a partly sectional plan on the line x. y.
Figure 5 of a mode of connecting the bearing to a Cycle vertical frame, wherein
the bracket g is formed with a round hole at one end, and through which the
hollow tube o is passed and fixed thereto.
Figures 7. 8. 9. and 10 represent different forms and modes of connecting the
bracket g to the hollow frames o of Cycles.
Figure 11 represents the bearing as applied to a set of springs, the bracket g
being bolted thereto by the pins i and nuts m.
Figures 12 and 13 represent respectively a side and front elevation of one
modification of the Invention as applied to axle boxes. The trunnions 6 being fitted
into sliding blocks r, work between and are guided, by the frames t. The said
blocks r may be prevented from falling out by the trunnions being lengthened and
a checkpin put through the ends. The axle u is fitted as usual into the shell or
box a, the top of said box being made so as to slide transversely and bear against
the bottom of the spring v, a friction plate being interposed between them.

page_text: Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
Constructing shells, cases, or boxes of bearings with two trunnions; and modes
of mounting same, substantially as and for the purposes described and shown.
