PROVISIONAL SPECIFICATION.
Improvements in or relating to Bearings for Velocipedes or other
Vehicles.
I, THOMAS HUMBER of Broadgate Villa, Beeston in the County of Nottingnam,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to bearings for velocipede or other vehicle wheels or
their journals which are not secured to the framing but which have a limited
movement irrespective of the framing against the action of a spring or springs for
the purpose of decreasing vibration.
In carrying out this invention the bearing is formed by or carried by sliding
blocks formed with recesses so as to slide between preferably two pins of a circular
or other suitable section, the two pins forming a slide for each block and carried
at each end in a clip secured to the framing; each clip is formed with a joint
between the pins one part sliding on or in the other and being secured preferably
by a bolt which thus forms a means of adjusting the distance between the pins and
compensating for wear.
To provide a means of adjustment 1 preferably connect the ends of the pins
forming each slide by screws passing through one of them and screwing into the
other, or if desirable two screws may be employed at each end one acting against
the other.
The sliding blocks are connected to the framing by springs of any suitable form
and arranged in any suitable manner so as to reduce the amount of vibration
communicated to the framing by the wheels.
The arrangement as described is especially applicable to the driving or rear
wheel of a safety bicycle the main axle of the driving wheels of a tricycle or
tandem and other like cases where existing anti-vibration arrangements are
inapplicable.
Considerable modification in detail may be made without departing from the
spirit of this invention.

COMPLETE SPECIFICATION.
Improvements in or relating to Bearings for Velocipedes or other
Vehicles.
I, THOMAS HUMBER, of Broadgate Villa, Beeston, in the County of Nottingham,
Engineer, 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 the bearings of the wheels of velocipedes or other
vehicles which are not secured directly to the framing but have a limited move-
ment irrespective of the framing against the action of a spring or springs for the
purpose of decreasing vibration.
It will be best understood by reference to the accompanying drawings in which
Fig. 1 is a side elevation and Fig. 2 a back view showing my invention applied
to the driving or rear wheel of a safety bicycle, and
Fig. 3 is a plan showing the construction of the clips carrying the slide-bars.
Like letters indicate like parts throughout the drawings.

formed
The two ends of the axle a of the wheel are carried in slide-blocks
with recesses so as to slide and be retained between two preferably cylindrical slide-
bars c.
The two slide-bars c are carried at each end by clips d secured to the
framing each preferably formed in two parts the inner part d' sliding within
the outer part and these parts are secured together by screws passing through
them, the holes in the inner part d' through which the screw passes being slotted
so that the distance between the slide-bars may be adjusted so as to allow of
compensation for wear.
Both parts dd' of the clips are preferably cut partially through the centre as
shown so that the screws close them on the slide bars c when they are screwed up
and securely lock them in position.
To provide a means for accurately adjusting the distance between the slide-bars c
the two ends of each pair are connected by screws y passing through one of them
and screwing into the other, or if desired two screws may be employed at each
end, one acting against the other.
The slide blocks or as shown the two ends of the axle a may be connected to
a downward extension e' of the framing by springs which take the weight of the
rider and absorb or reduce the amount of vibration communicated to the framing
by the wheels. These springs may be connected to the extensions e¹ by means
of hooks or equivalent devices but preferably they are connected to the extensions
by means of screws passing through said extensions and fitted with nuts so
that the tension of the springs may be adjusted to suit riders of varying weights.
The arrangement as described is specially applicable to the driving or rear
wheel of a safety bicycle the driving wheel axle of a tricycle or tandem, and other
vehicles where existing anti-vibration arrangements are inapplicable.
It is obvious that considerable modification may be made in the details of the
before described apparatus without departing from the spirit of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In a bearing for cycles and similar vehicles the combination with slide bars
such as e between which the slide block works of adjustable clips such as d d' and
adjusting screws such as g substantially as described and illustrated in the accom-
panying drawings.
2. In a bearing for cycles and similar vehicles the combination with an axle
such as a carried in a reciprocating slide block such as of springs such as h
connected at one end with the axle outside the bearing and at the other with a
framing extension such as e' in such a manner that the strength of the springs
may be adjusted substantially as described and illustrated in the accompanying
drawings.
3. In a bearing for cycles and similar vehicles the combination with slide bars
such as c of an adjustable clip such as d d' and screw substantially as described
and illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete adjustable
spring bearing substantially as described and illustrated in the accompanying
drawings.
