Improvements in Bicycles, Tricycles and other Velocipedes and in
Motor Cycles.
We, GEORGE MABBUTT, of Mayfield Villas, Avenue, Acock's Green, in the County
of Worcester, Machinist, and BARNET GEORGE PRICE, of No. 50 William Street,
Aston near Birmingham, in the County of Warwick, Machinist, do hereby declare
the nature of this Invention to be as follows:-
Our invention relates to the attaching of the spindles of the steering and other
wheel or wheels of bicycles, tricycles and other velocipedes and motor cycles to the
forks of the same and consists of the improvements in the method of attaching the
said spindles to the forks hereinafter described.
In order that our invention may be the better understood we remark that on the
slackening of the screw nuts on the screwed ends of the spindles of velocipede and
the like wheels as ordinary constructed for the adjustment or assemblage of the
parts, the spindles become capable of a turning or rotary motion in the ends of the
forks, which turning or rotary motion it is the object of our invention to prevent.
We will describe our invention in connection with the spindles of the wheels of a
safety bicycle.
We will first describe the attaching of the spindle of the front or steering wheel
to the fork of the same.
We make a flat on one side of one of the screwed ends of the spindle and we make the
hole in the washer which takes on the said flat-sided screwed end of the spindle of a
shape suitable to fit the said flat-sided screwed end; that is to say, the said hole has
a shape somewhat resembling the letter D. We will hereinafter call the said
washer the D washer. On the inner face of the D washer we provide a teat, peg,
or projecting pin and in the cylindrical hole in the end of that branch of the fork
against which the said D washer bears we make a notch or indentation with which
the teat, peg, or projecting pin on the washer engages when the said washer is in
position on the spindle. The D washor is kept in place by the screw nut which
takes on the flat-sided screwed end of the spindle. By this means the rotation of
the spindle when the screw nuts on the ends of the same are relaxed is prevented.
The projecting pin on the D washer may engage in a hole in the end of the branch
of the fork instead of engaging in a notch or indentation in the circular hole through
which the flat-sided screwed end of the spindle passes.
Instead of employing a D washer of the kind described, we may use plates shaped
to slide on the ends of the branches of the fork one of the said plates having
a D shaped hole for the flat-sided screwed end of the spindle to engage in. In this
case we prefer to turn up the lower ends of the sliding plates so as to form tubular
sockets for the ends of the mud guard stay to engage in.

page_text: In applying our invention to the attaching of the spindle of the back wheel to the
back wheel fork we flatten one end of the spindle as described with respect to the
spindle of the steering wheel and we make the hole or eye in one of the draw bolts
of the driving chain adjusting mechanism of a shape somewhat resembling the
letter D or of a shape suitable for the flattened end of the spindle to engage in and
fit. Or we employ draw bolts with circular holes and use in conjunction therewith
a washer on the inner side of the slotted end of one of the branches of the fork in
which the back wheel spindle slides on the adjustment of the tension of the driving
chain, the said washer having a D shaped hole for the flat-sided screwed end of the
spindle to fit and projecting parts or pins for engaging in the slot in the branch of
the fork to prevent the turning or rotary motion of the said washer.
Our improvements may be readily applied to velocipedes and the like of the
ordinary construction.

Improvements in Bicycles, Tricycles and other Velocipedes and in
Motor Cycles.
We, GEORGE MABBUTT, of Mayfield Villas, Avenue, Acock's Green, in the County
of Worcester, Machinist, and BARNET GEORGE PRICE, of No. 50 William Street,
Aston near Birmingham, in the County of Warwick, Machinist, do hereby declare
the nature of our invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:--
Our invention relates to the attaching of the spindles of the steering and other
wheel or wheels of bicycles, tricycles and other velocipedes and motor cycles to the
forks of the same; and consists of the improvements in the method of attaching the
said spindles to the forks hereinafter described.
In order that our invention may be the better understood we remark that on the
slackening of the screw nuts on the screwed ends of the spindles of velocipede and
like wheels as ordinarily constructed for the adjustment or assemblage of the parts,
the spindles become capable of a turning or rotary motion in the ends of the forks,
which turning or rotary motion it is the object of our invention to prevent.
We will describe our invention in connection with the spindles of the wheels of a
safety bicycle.
We will first describe the attaching of the spindle of the front or steering wheel
to the fork of the same.
We make a flat on one side of one of the screwed ends of the spindle and we
mako the hole in the washer which takes on the said flat sided screwed end of the
spindle of a shape suitable to fit the said flat-sided screwed end; that is to say, the
said hole has a shape somewhat resembling the letter D. We will hereinafter call
the said washer the D washer. On the inner face of the D washer we provide a
teat, peg or projecting pin and in the cylindrical hole in the end of that branch of
the fork against which the said D washer bears we make a notch or indentation with
which the teat, peg or projecting pin on the washer engages when the said washer is
in position on the spindle. The D washer is kept in place by the screw nut which
takes on the flat sided screwed end of the spindle.
By this means the rotation of the spindle is prevented when the screw nuts on the
ends of the same are relaxed.

page_text: This part of our invention is illustrated in Figures 1, 2 and 3 of the accompanying
Drawing.
Figure 1 represents in elevation the hub of the front wheel of a safety bicycle and
a portion of the steering fork of the said wheel, one of the branches of the fork being
partly in section.
Figure 2 represents in side elevation one of the branches of the steering fork and
Figure 3 represents in side elevation and edge view the D washer which is passed
onto the screwed end of the wheel spindle and engages with the branch of the
steering wheel fork represented in Figure 2.
The same letters of reference indicate the same parts in the several figures of the
Drawing.
a is the hub of the front or steering wheel and b, b¹ the screwed ends of the
spindle of the same; c, c¹ are the two branches of the steering wheel fork. In
carrying our invention into effect we make a flat on the screwed end b of the
spindle as will be seen by reference to the end view of the said spindle bracketted to
Figure 1, and we make the hole in the washer d (Figure 3) of a size and shapo
proper to fit the said end 6 of the spindle. We provide the washer d with a pin,
peg or projection d' and make in the hole in the branch o of the steering wheel fork,
through which the end 6 of the spindle b, b protrudes when in place, a notch c² to
receive the pin, peg or projection d².
It will thus be understood that when the wheel of the bicycle is mounted in its
fork the spindle is prevented from rotating on the passing of the washer d on to the
flat-sided end of the spindle and engaging the pin d' of the said washer d in the
notch e of the branch of the steering wheel fork and thus the screwing home of
the outside screw nuts e, e is facilitated. Further, when for any purpose it is desired
to slacken or remove one or other or both of the screw nuts e, e the spindle while
being loosened is not permitted to rotate as is the case in ordinary velocipedes.
The projecting pin d' of the washer & instead of engaging in a notch o² in the
circular hole through which the flat-sided screwed end b of the spindle b, 6 passes,
may be made to take in a detached or separate pin hole made in the branch c of the
steering wheel fork.
Instead of employing washers d of the kind hereinbefore described and represented
in Figures 1 and 3 we may use plates shaped to slide on the ends of the branches of
the fork, one of the said plates having a D shaped hole for the flat-sided screwed
end 6 of the spindle to engage in. In this case we prefer to turn up the lower ends
of the sliding plate so as to form tubular sockets for the ends of the mudguard stay
to engage in.
This part of our invention is illustrated in Figure 4. d is the washer plate.
referred to, the D shaped hole in which engages with the flat-sided end of the
wheel spindle. The washer is fixed so as to prevent the rotation of the wheel
spindle by ear pieces d, de formed on opposite sides of the washer plate d which ear
pieces take upon or clip opposite sides of the branch c of the steering wheel fork.
The lower or extreme ends of the washer plates d, at each side of the steering fork,
are formed into tubular sockets d³ for receiving and supporting the mud-guard
stays of the front wheel of the bicycle.
In applying our invention to the attaching of the spindle of the back wheel to the
back wheel fork we flatten one end of the spindle as described with respect to the
spindle of the steering wheel and we make the hole or eye in one of the draw bolts
of the driving chain adjusting mechanism of a shape somewhat resembling the
letter D or of a shape suitable for the flattened end of the spindle to engage in and fit.
This part of our invention is illustrated in Figures 5 and 6.
fis the flat-sided end of the spindle of the rear wheel occupying the forked ends g¹, g¹
of the branches of the back wheel fork g.g. In order to prevent the spindle rotating
on the slackening or removal of the outside screw nuts e we make the eye or hole in
the draw bolt & to be used at the end of the spindle ƒ of a size and shape suitable to
fit the said end of the spindle as will be understood by reference to the elevation of
the screw bolt separately represented in Figure 6.

page_text: Or we may employ ordinary draw bolts that is, draw bolts with circular eyes, at
both ends of the spindle. In this case we employ on the flat sided end f of the spindle
and preferably at the inner side of the forked end g', g' of the branch of the rear
wheel fork g, a washer d of the kind represented in side elevation and edge view in
Figure 7. The said washer is provided with projections d', d' which engage in the
slot of the forked end g¹, g', the screwed stem of the ordinary draw bolt h passing
between the projections d², d.
Or we may employ at the flat sided end f of the spindle a draw bolt h having a
circular eye with a notch h² therein as is represented in Figure 8 and use in
combination therewith a washer d of the kind represented in Figure 3. The
engagement of the pin d' of the washer d (Figure 3) in the notch h² of the draw
bolt prevents the rotation of the washer and the shape of the hole in the washer d
prevents the rotation of the spindle.
Our improvements may be readily applied to velocipedes and the like of the
ordinary construction.
Having now particularly described and ascertained the nature of our
invention and in what manner the same is to be performed we declare that what
we claim as our invention of "Improvements in bicycles, tricycles and other
velocipedes and in motor cycles ";-
First. Preventing the rotation of the spindles of velocipede wheels on the
assemblage or adjustment of the parts, by making a flat on one of the screwed ends
of the spindle and using in combination therewith a washer having a correspondingly
shaped hole to fit the flat-sided end of the spindle, the said washer being provided
with a pin, peg or projection on its inner side for engaging in a notch or hole in the
branch of the wheel fork substantially as described and illustrated in Figures 1, 2
and 3 of the accompanying Drawing.
Secondly. The modified method of preventing the rotation of the wheel spindle
herein before described and illustrated in Figure 4 of the accompanying Drawing, the
said modified method consisting in the use on the flat-sided end of the spindle of a
washer plate with ear pieces for engaging on opposite sides of the branch of the
fork substantially as described and illustrated.
Thirdly. Preventing the rotation of the spindles of the rear wheels of bicycles
and other velocipedes on the assemblage or adjustment of the parts by making a flat
on one of the screwed ends of the spindle and using at that end of the spindle a
draw bolt with a hole suitable to fit the flat-sided end of the spindle substantially as
described and illustrated on Figures 5 and 6 of the accompanying Drawing.
Fourthly. The modifications herein before described with reference to Figures 7
and 8 of the accompanying Drawing the said modifications consisting in using in
combination with a spindle with a flat-sided end, an ordinary draw bolt and a washer
of the kind represented in Figure 7; or using a draw bolt of the kind represented
in Figure 8 in combination with a washer of the kind represented in Figure 3.
