PROVISIONAL SPECIFICATION.
Improvements appertaining to Bearings for Velocipedes and like
Vehicles.
I, JOHN EDMONSTON WISHART, of South View Cross Hills, near Keighley, in the
County of York, Designer, do hereby declare the nature of this invention to be as
follows, that is to say:-
It has reference to an improved locking device for use in connection
with adjustable antifriction bearings for the wheels of velocipedes and
like vehicles, wherein said adjusting pieces are required to be firmly secured in
position and consists according to one arrangement, in the formation and construc-
tion of an attachment that may be readily secured in position for performing its
functions and which when moved to allow adjustment does not become detached
and liable to be lost as do many locking devices heretofore employed.
In carrying this part of my invention into effect the screwed adjusting piece
of the antifriction bearings has longitudinal serrations made in its periphery or
through the threads thereon in order to receive the extending end of a hinged
catch-piece mounted upon the hub or other part into which the screwed adjusting
piece fits.
The part of the hub or the like where the hinged catch-piece is mounted is
appropriately recessed to receive same, while the upper surface of the projecting
portion from said catch-piece descends below the peripheral surface of the adjustable
screwed part in order that when the outer nut is finally tightened up it will take
over this projecting portion thus firmly holding it in position while when screwed
home it will make a perfect joint for the exclusion of dirt.
According to another arrangement for locking the part above referred to, I
employ a detachable washer instead of the catch-piece as under certain conditions
it may be of cheaper production, and this washer is formed to fit over a series of
projections on the hub, concentric and parallel with its axis.
Extending inwardly from the washer's rim, is a pin or projection which will
take into one or other of the spaces intervening between the projections on the hub
and extend through same to reach into a recess made in the bearings' adjusting
piece, by which means when this latter is adjusted as desired the projection on the
washer is passed through the interstice on the hub, which happens to be opposite
the opening in said adjusting piece, and forward into the recess in said adjusting
piece so that on the outer nut being tightened up the whole are firmly held as
desired.
As a modification of this latter arrangement instead of the hub having any
projections formed on it, it may have the catch-piece first before described, mounted
thereon while a loose washer fitting over a flattened part of the screwed adjusting
piece may be arranged to have serrations in its periphery to receive said catch-

Improvements appertaining to Bearings for Velocipedes and like
Vehicles.
I, JOHN EDMONSTON WISHART, of South View Cross Hills, near Keighley, in the
County of York, 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, that is to say:-
It has reference to an improved locking device for use in connection
with adjustable antifriction bearings for the wheels of velocipedes and
like vehicles wherein said adjusting pieces are required to be firmly secured in
position and consists according to one arrangement, in the formation and construc-
tion of an attachment that may be readily secured in position for performing its
functions and which when moved to allow adjustment does not become detached
and liable to be lost as do many locking devices heretofore employed.
According to another arrangement for locking the part above referred to, I
employ a detachable washer instead of the catch-piece, as under certain conditions
it may be more cheaply produced.
However, in order that my said invention may be readily understood I have
hereunto appended sheets of drawings illustrative thereof to which reference is
made in the following description.
Figs. 1 and 2 are side and sectional end elevations of a wheel's hub showing the
form of locking device herein first before referred to.
Figs. 3 and 4 are similar views to Figs. 1 and 2 respectively but illustrate the
device referred to as an alternative construction.
Figs. 5 and 6 are also similar views to Figs. 1 and 2 but illustrate further
modifications hereinafter described.
Figs. 7 and 8 are end elevations of the bearings for the crank spindle of a
velocipede and show how my methods of locking the parts thereon may be used
in connection therewith.
Figs. 9 and 10 are drawings in detail hereinafter referred to.
In carrying the first part of my invention into effect, the screwed adjusting
piece a has longitudinal serrations 6 made in its periphery or through the threads
thereon in order to receive the extending end c¹ of a hinged catch-piece c pivoted
at c¹, upon the hub d, or upon the bracket or bearing f (see Fig. 7) into which
the screwed adjusting piece a fits.
The part of the hub or bracket f where the catch c is mounted is suitably
recessed to receive same, while the upper surface of this catch c, when placed into
position for its end to enter the piece a to hold or retain same, is brought flush
with the periphery of the part d or f upon which it is mounted so that by screwing
the covering nut g home upon and over the piece a its extending flange g¹ will
cover and retain said catch c in position to the exclusion of all dust or dirt.
As to the second part of my invention instead of the catch e I make use of a
detachable washer h formed to fit over a series of projections k on the hub d or
bracket concentric and parallel with its axis.

page_text: Extending inwardly from the washer's rim is a pin or projection h¹ which will
take into one or other of the spaces intervening between the projections k, and
extend through same to reach into a recess m made in the piece a, by which means
when this latter is adjusted as desired the projection h¹ is passed through the
interstice on the hub or bracket f which happens to be opposite the opening or
recess m, and forward into said recess so that on the outer nut g being tightened
up, the whole are firmly held as desired.
As a modification of this latter arrangement instead of the hub d or bracket f
having any projections formed on them, they may have the catch c mounted
thereon as shown by Fig. 6, while a loose washer p fitting either over a flattened
part on (or by having a small projection 2 formed on it to fit into a recess in) the
piece a may be arranged to have serrations p" in its periphery to receive said
catch c instead of the series of indentations for same being made in the piece
as shown by said Fig. 2.

Although I have only described and illustrated my invention in connection with
the hub of a wheel and the hearings for a spindle, it will be clearly seen that same
may be used in connection with any similarly constructed and operating parts of
velocipedes and like vehicles.
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. In a locking device for the parts described, a hinged catch, screwed adjusting
piece with recesses to receive said catch, and a nut for covering and securing said
catch in position the same being constructed and arranged in combination substan-
tially as herein specified.
2. In a locking device for the parts described a detachable washer having an
internally projecting part to act in conjunction with the other devices substantially
as herein set forth.
3. The improved means for locking the screwed adjusting parts herein described
the same being constructed and arranged substantially as specified.
