Improvements in Velocipedes.
I, RICHARD PURCELL FUGE, of Glenally, Youghal, in the County of Cork,
Ireland, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in velocipedes and is designed to provide
for rapid and easy removal of the driving wheel of a chain geared velocipede for
tyre repairs and other purposes.
Instead of securing the driving wheel spindle in position in the frame directly by
means of nuts on the end thereof I secure to the ends of the said spindle, blocks or
pieces, preferably of steel and of oblong form, which are better adapted to form a
good mechanical connection with the frame than are the spindle ends alone.
provide means for securing these blocks in the frame so that it is unnecessary in
removing the wheel to first remove the chain from either of the cog wheels.
I also
These blocks or pieces (hereinafter referred to as blocks) are securely clamped
on the ends of the spindles between the nuts, with which the spindles are provided
in the usual manner, and the ball bearings, the spindle passing through slots or
perforations in the same.
In cases where the blocks are slotted, the slots permit of adjustment of the wheel
to allow for stretching of the chain from time to time without interfering with the
main connection of the wheel spindle and frame. In such cases the edges of the
siots may either be straight and smooth or they may be scalloped or otherwise
formed as may be desirable. If scalloped it is easy, by counting the number of
scallops, to move the wheel evenly at each side when tightening the chain.
According to one arrangement I provide, on those parts of the frame that are to
support the ends of the spindle, enlargements having recesses therein adapted to
receive the aforesaid blocks, the walls of the recesses taking into grooves in the
edges of the blocks to afford a better connection. The recesses may be open at
their under sides and be provided with hinged pieces having winged or other fixing
screws at their free ends to firmly hold the blocks in place. Or they may be open
at their inner ends and the blocks may be fixed in position by one or more screws
passing through the enlargement and engaging with, or entering tapped holes in,
the said blocks. In either case in order to remove the wheel it is merely necessary
to withdraw aforesaid screws and move the blocks out of the recesses in a down-
ward or inward direction as the case may be. In neither case is it necessary to
move the spindle and wheel outward, so that removal of the driving chain is
obviated.
Instead of securing the blocks in recessed enlargements as described I may fix
them to flat bearing surfaces on the undersides of the corresponding parts of the
frame, by means of one or more screws passing through the blocks and tapped into
the said parts of the frame. In this case the blocks are simply perforated instead
of being slotted and adjustment for stretching of the chain is obtained by inserting
the screw or screws in one or other of a number of holes with which the bearing
surfaces are provided. In some instances the parts of the frame in which the
wheel is secured may be hinged or jointed at one side so that when the wheel
spindle (which may be supported as before described at one or both ends) is
detached from the frame on one side, the wheel can be sufficiently moved to allow
of the tyre or air tube thereof to be passed in between the wheel boss and the
frame. Or the stays which carry the driving wheel may be jointed or hinged, so

page_text: that the part or parts which extend to the bearing can, by disconnecting the said
joint or hinge be turned on the bearing part as a pivot so as to leave a gap or gaps
for the passage of the tyre or air tube.

Improvements in Velocipedes.
I, RICHARD PURCELL FUGE, of Glenally, Youghal, in the County of Cork,
Ireland, Gentleman, do hereby declare the nature of this invention and in what
manuer the same is to be performed to be particularly described and ascertained in
and by the following statement:-
This invention relates to improvements in velocipedes and, is designed inter alia
to provide for rapid and easy removal of the driving wheel of a chain geared
velocipede for tyre repairs and other purposes.
Instead of securing the driving wheel spindle in position in the frame directly by
means of nuts on the end thereof as heretofore, I secure to the ends of the said
spindle, blocks or picces, preferably of steel and of oblong form, which are better
adapted to form a good mechanical connection with the frame than are the spindle
ends alone. I also provide means for securing these blocks in the frame so that it
is unnecessary, in removing the wheel, to first remove the chain from either of the
cog wheels.
These blocks or pieces (hereinafter referred to as blocks) are securely clamped
on the ends of the spindles, between the nuts, with which the spindles are provided
in the usual manner, and the ball bearings, the spindle passing through slots or
perforations in the said blocks.
In cases where the blocks are slotted, the slots permit of adjustment of the
wheel, to allow for stretching of the chain, from time to time without interfering
with the main connection of the wheel spindle and frame. In such cases the edges
of the slots may either be straight and smooth, or they may be scalloped or
otherwise formed as may be desirable. If scalloped it is easy, by counting the
number of scallops, to move the' wheel evenly at each side when tightening the
chain.
Referring to the accompanying drawings,
Fig. 1 is a side elevation of the rear end of the frame of a velocipede constructed
according to this invention;
Fig. 2 is a cross section through the frame on the line A B Fig. 1.
Fig. 3 is a similar view to Fig. 1, the parts being shewn in the position they
occupy when the wheel is being removed.
According to this arrangement I provide, on each of those parts 1 of the frame
that are to support the ends of the spindle 2, an enlargement or bearing part 1
having a recess 3 therein adapted to receive a block 4 which is clamped on the
spindle between the nut 5 and ball bearing 5 the walls of the recess taking into
grooves 6 formed in the edges of the block to afford a better connection. Each
recess 3 is open at its under side and is provided with a hinged piece 7 for closing
the same; the hinged piece is provided at its free end with a screw 8 which takes
into a tapped hole in the frame and fixes the hinged piece in its closed position and
thus serves to firmly hold the block in place. It will be readily understood upon
reference to Fig. 3 that the wheel may be rapidly and easily removed by releasing
the screws 8, lowering the hinged pieces as shewn and moving the blocks in a
downward direction.

page_text: Figs. 4 and 5 are similar views to Figs. 1 and 3 respectively of a modification in
which the recesses 3 are open at their inner or front ends and the blocks 4 are fixed
in position by screws 8 passing through the rear ends of the enlargements and
entering tapped holes in the said blocks. If desired more than one screw may be
employed to secure each of the blocks in place and they may be arranged to engage
with the blocks in other ways than by entering tapped holes therein.
In order to
remove the wheel it is merely necessary to withdraw the screws and move the
blocks out of the recesses in an inward or forward direction. In Figs. 4 and 5 the
edges of the slots in the blocks are shewn scalloped to enable the wheel to be
evenly adjusted when taking up slack in the chain. To do this the blocks are
removed from the spindle ends and replaced so that each of the said ends lies
between a different pair of scallops.
Instead of securing the blocks in recessed enlargements as described they may be
arranged as illustrated in side elevation in Fig. 6. The blocks are fixed to flat
bearing surfaces 9 formed on the undersides of the corresponding parts 1ª of the
frame, by means of one or more screws 8 passing through the blocks and screwed
into tapped holes in the said parts of the frame. In this case the blocks are simply
perforated instead of being slotted and adjustment for stretching of the chain is
obtained by inserting the screws in one or other of a number of holes 8* formed in
the bearing surfaces or parts 1ª.
In velocipedes constructed according to this invention it is not necessary to move
the spindle and wheel outward or sidewise when taking it out of the frame so that
removal of the driving chain is obviated.
In some instances the parts 1 of the frame in which the wheel is secured may be
hinged or jointed at one side to the main portion of the frame so that when the
wheel spindle (which may be supported as before described at one or both ends) is
detached from the part 1 of the frame on the other side, the wheel can be
sufficiently moved in a lateral direction to allow of the tyre thereof being passed in
betw the wheel boss and the said part 1 of the frame. Or the stays or parts 1
which carry the driving wheel may be so jointed or hinged that the part or parts
which extend to the bearing can, upon disconnecting the said parts be turned on the
bearing part as a pivot so as to leave a gap or gaps for the passage of the tyre.
Fig. 7 illustrates in side elevation part of a rear driving safety bicycle according
to this invention.
Fig. 8 is a sectional plan of part of one of the stays.
The stays 1 on one side of the frame in this arrangement are jointed respectively
at 10, 10 to the main portion 11 of the frame to which they are connected by any
suitable means such as screw bolts. The arrangement is such that upon the stays 1
at one side being disconnected from the frame 11 at the points 10, 10 and the
nuts 5 being slackened, the said stays 1 can be turned about the axis of the wheel
spindle as a centre into the position shown in dotted lines in Fig. 7, in which
position the tyre can be readily removed from or replaced upon the wheel without
detaching the latter from either set of stays and without detaching the opposite set
of stays from the main frame.
Figs. 9 and 10 shew a modification of this arrangement in which the stays 1 are
hinged at 12, 12" to the bearing part 1, their free ends being jointed as above
described at 10, 10" to the main portion of the frame 11. This arrangement
permits of the stays being easily turned into the positions indicated in dotted lines
for the purpose hereinbefore explained.
Instead of hinging the stays at the required points 12, 12" they may be made
sufficiently elastic to allow of their being sprung away from the main frame to the
required extent, when detached from such frame.
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. A chain geared velocipede in which the ends of the driving wheel spindle

page_text: are carried in blocks or bearings held within recesses that are formed in the
velocipede frame, and are either open at the bottom or at the forward or inner end,
"the arrangement in each case being such that the blocks or bearings can be moved
out of the recesses either in a downward or in an inward direction so as to permit
of the removal of the wheel without detaching it from its spindle, and without
removing the driving chain therefrom substantially as herein described.
2. Mounting the driving wheel spindle of a velocipede in blocks or supports
constructed and arranged substantially as hereinbefore described with reference
respectively to and shown in Figs. 1, 2 and 3; in Figs. 4 and 5; and in Fig. 6 of
the drawings annexed.
3. A velocipede in which one of the sets of side stays carrying a wheel spindle
are hinged or jointed to the main frame in such a manner that when the wheel
spindle is detached from the opposite set of stays the wheel and the set of stays
then carrying it can be moved sufficiently from such opposite set of stays. to permit
of the wheel tyre being passed between them and the wheel boss substantially as
herein described.
4. A velocipede in which the stay or stays at one side of a wheel is or are
-detachably connected to the main frame and is or are capable when detached of
being moved so as to leave a gap or gaps for the passage of the wheel tyre
between it or them and the main frame substantially as herein described for the
purpose specified.
5. A velocipede in which the stays or some of them carrying a wheel, are so
jointed to the main frame that the part or parts thereof which extend to the bearing
of the wheel spindle can upon being disconnected be turned on the bearing part or
spindle as a pivot so as to leave a gap or gaps for the passage of the wheel tyre
substantially as herein described.
6. A velocipede having the stays at one side of a wheel connected and arranged
substantially as herein before described with reference respectively to and shown in
Figs. 7 and 8, and in Figs. 9 and 10 of the drawings annexed.
