PROVISIONAL SPECIFICATION.
Improvements in Bicycles, Tricycles, and other Velocipedes.
We, WILLIAM ALLDAY of Springfield, Moseley in the County of Worcester
Manufacturer and EDMUND ALLDAY of Spring Coppice, Knowle, in the County
of Warwick Manufacturer do hereby declare the nature of this invention to be as
follows:-
Our invention consists principally of the improvements hereinafter described in
certain parts of bicycles, tricycles and other velocipedes whereby the adjustment
of the height of the handle bar column in the steering fork standard, and the seat
pillar in its tubular socket or post, as well as the adjustment of the position of the
handle bar in its clip or socket at the head of the handle bar column are readily
and efficiently effected.
Our invention consists further in adjusting the length of the break rod and
adjuncts connected with it and also the minor details and parts hereinafter
described.
For the purpose of adjusting the height of the sliding handle bar column and
fixing it to the tubular steering fork standard, working in the socket on the
fixed framing of the velocipede, we make the upper part of the said tubular
steering fork standard conical or taper internally into which part we fit an
elastic steel bush. This bush is cylindrical internally for the handle bar column
to slide in and the greater part of the said steel bush is taper externally corre-
sponding with the taper of the mouth of the tubular steering fork standard, but
the upper external part of the said bush joins the long tapering part by a quick
and short tapering portion. The said bush is made elastic by parallel slits.
The conical top of the tubular steering fork standard is screwed externally and
a screw nut works on it. The top of this screw nut is made taper or conical
internally to correspond with the short taper top of the elastic steel bush. The
handle bar column being passed by a sliding motion into the tubular steering fork
standard so as to adjust its height therein, the screw nut is driven home upon
the screwed top of the tubular steering fork standard. The slit elastic steel bush
is thereby enclosed by the said screw-nut and the taper part of the latter acting
upon the short taper part of the steel bush compresses it upon and causes it to
clip forcibly the handle bar column, at the same time forcing the long taper part
of the said bush into the taper seat of the tubular steering fork standard. The
handle bar column is thereby effectually locked to the tubular steering fork
standard. A lock nut may be used with the taper screw nut described for
additional security.
For the purpose of holding or fixing the telescopic brake rod in any desired
position, we make the mouth of the tube in which the brake rod slides, slit and
taper it externally and beyond the taper part the said tube is screwed. By
screwing a screw nut having an internal conical part, upon the taper and slit
end of the tube, the elastic end of the tube is compressed upon the brake rod
and the latter fixed in its adjusted position in the tube.
We adjust the position of the collar or abutment by which the required
tension is put on the coiled spring of the brake rod by an arrangement of parts
similar to that last described.
In order to adjust the handle bar in the position most suitable for the rider
we employ the following combination of parts. On the middle of the handle bar
we braze a collar having an annular groove in it. On the top of the handle bar
column is an eye or perforated lug in which the handle bar can turn or have an
angular motion for adjusting its position vertically. In this eye or lug is a taper

page_text: hole in which a vertical pin slides, the lower part of the said pin being plain and
taper and having a flat and the upper part screwed. The said pin is raised or
lowered in the taper hole by a collar screw nut, having only a rotatory motion, the
collar part of the screw nut working in an undercut recess in the eye or lug on the
top of the handle bar column. Having adjusted the position of the handle bar in
the said eye or lug, the taper and screwed pin is put in its place in the vertical
taper hole in the eye or lug. By turning the collar screw nut, the taper pin is
raised and its taper part made to bear against the annular groove in the collar on
the handle bar, whereby the said bar is locked or held firmly in its adjusted
position at the top of the handle bar column. By giving a downward motion to
the taper pin its taper part is withdrawn from the groove in the collar of the
handle bar and the latter unfastened.
The centre on which the brake lever turns is provided with an elastic clip
capable of adjustment on the handle bar after the latter has been adjusted in the
manner before described.
For the purpose of adjusting the sliding seat pillar in the clip on the frame of
the velocipede we tighten the said clip upon the seat pillar for fixing its position
or expand the said clip to release the seat pillar by the following combination of
parts. Between the lugs of the clip we place two fixed screws, one right handed
and the other left handed, a screw nut between and working upon them having
corresponding right and left handed screw threads. By turning the said screw nut
in one or other direction the clip may be compressed upon or opened from the seat
pillar for fixing or releasing it. We prefer to make the two screws described from
tubing the outer end of each piece of tubing having an expanded conical flange.
These conical flanges fit in corresponding shaped seats in the lugs of the pillar clip.
To prevent the rotation of the tubular screws in their seats, a rib or projection on
the conical flange fits into a depression in the conical seat on the lug of the
pillar clip.
Our invention consists further of a pedal for velocipedes in which pedal the
ordinary rat trap foot plate is combined with an india rubber pad foot rest so that
one or other may be used at the will of the rider. For this purpose we use a bar
or plate having on one edge teeth of the rat trap pattern and at right angles to this
plate, we fix a second plate which is perforated for carrying the india rubber pad.
This compound pedal rest is fitted to the pedal end plates and fixed by screw nuts
in such a position that either the rat trap plate can be used by the rider or the
india rubber pad plate.

Improvements in Bicycles, Tricycles, and other Velocipedes.
We WILLIAM ALLDAY of "Springfield" Moseley in the County of Worcester
Manufacturer and EDMUND ALLDAY, of "Spring Coppice," Knowle in the County
of Warwick, Manufacturer do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
Our invention consists principally of the improvements hereinafter described in
certain parts of bicycles, tricycles and other velocipedes whereby the adjustment of
the height of the handle bar column in the steering fork standard and the seat
pillar in its tubular socket or post, as well as the adjustment of the position of the
handle bar in its clip or socket at the head of the handle bar column are readily
and efficiently effected.
Our invention consists further in adjusting the length of the brake rod and adjuncts
connected with it and also the minor details and parts hereinafter described.

page_text: The
For the purpose of adjusting the height of the sliding handle bar column and
fixing it to the tubular steering fork standard, working in the socket on the fixed
framing of the velocipede, we make the upper part of the said tubular steering fork
standard conical or taper internally into which part we fit an elastic steel bush.
This bush is cylindrical internally for the handle bar column to slide in and the
greater part of the said steel bush is taper externally corresponding with
the taper of the mouth of the tubular steering fork standard, but the upper
external part of the said bush joins the long tapering part by a quick and
short tapering portion. The said bush is made elastic by parallel slits.
conical top of the tubular steering fork standard is screwed externally and
a screw nut works on it. The top of this screw nut is made taper or
conical internally to correspond with the short taper top of the elastic steel
bush. The handle bar column being passed by a sliding motion into the tubular
steering fork standard so as to adjust its height therein, the screw nut is driven
home upon the screwed top of the tubular steering fork standard. The slit elastic
steel bush is thereby enclosed by the said screw nut and the taper part of the latter
acting upon the short taper part of the steel bush compresses it upon and causes it
to clip forcibly the handle bar column, at the same time forcing the long taper part
of the said bush into the taper seat of the tubular steering fork standard.
handle bar column is thereby effectually locked to the tubular steering fork
standard. A lock nut may be used with the taper screw nut described for
additional security.
The
For the purpose of holding or fixing the telescopic brake rod in any desired
position we make the mouth of the tube in which the brake rod slides slit and taper
it externally and beyond the taper part the said tube is screwed. By screwing
a screw nut having an internal conical part, upon the taper and slit end of the tube,
the elastic end of the tube is compressed upon the brake rod and the latter fixed iu
its adjusted position in the tube.
We adjust the position of the collar or abutment by which the required tension
is put on the coiled spring of the brake rod by an arrangement of parts similar to
that last described.
In order to adjust the handle bar in the position most suitable for the rider we
employ the following combination of parts. On the middle of the handle bar
we braze a collar having an annular groove in it. On the top of the handle
bar column is an eye or perforated lug in which the handle bar can turn
or have an angular motion for adjusting its position vertically.
In this eye or
lug is a hole in which a vertical pin slides, the lower part of the said pin
being plain and taper and having a flat and the upper part screwed. The said pin
is raised or lowered in the hole by a collar screw nut, having only a rotary motion,
the collar part of the screw nut working in an undercut recess in the eye or lug on
the top of the handle bar column. Having adjusted the position of the handle bar
in the said eye or lug, the taper and screwed pin is put in its place in the vertical
hole in the eye or lug. By turning the collar screw nut the taper pin is raised and
its taper part made to bear against the annular groove in the collar on the handle
bar whereby the said bar is locked or held firmly in its adjusted position at the top
of the handle bar column. By giving a downward motion to the taper pin its
taper part is withdrawn from the groove in the collar of the handle bar and the
latter unfastened.
The centre on which the brake lever turns is carried by an elastic clip which is
tightened on the handle bar after the latter has been adjusted in the manuer before
described.
For the purpose of adjusting the sliding seat pillar in the clip on the frame of the
velocipede, we tighten the said clip upon the seat pillar for fixing its position or
expand the said clip to release the seat pillar by the following combination of
parts. Between the lugs of the clip we place two fixed screws one right handed
and the other left handed, a screw nut between and working upon them having
corresponding right and left handed screw threads. By turning the said screw nut

page_text: in one or other direction the clip may be compressed upon or opened from the seat
pillar for fixing or releasing it. We prefer to make the two screws described from
tubing the outer end of each piece of tubing having an expanded conical flange.
These conical flanges fit in corresponding shaped seats in the lugs of the pillar clip.
To prevent the rotation of the tubular screws in their seats, a rib or projection
on the conical flange fits into a depression in the conical seat on the lug of the
pillar clip.
Our invention consists further of a pedal for velocipedes in which pedal the
ordinary rat trap foot plate is combined with an india rubber pad foot rest, so that
one or other may be used at the will of the rider.
For this purpose we use a bar or plate having on one edge teeth of the rat trap
pattern and at right angles to this plate, we fix a second plate which is perforated
for carrying the india rubber pad. This compound pedal rest is fitted to the pedal
end plates and fixed by screw nuts in such a position that either the rat trap plate
can be used by the rider or the india rubber pad plate.
We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is to be performed.
Figure 1 represents in side elevation, a safety bicycle containing the several
improvements constituting our invention and
Figure 2 represents in front elevation the steering handle bar and its attachments;
Figures 3 to 29 represent the parts of the safety bicycle drawn to a larger scale.
Our method of adjusting and fixing the sliding handle bar column in the tubular
steering fork standard is best illustrated in the enlarged views Figures 3 to 11
both inclusive, Figure 3 representing in side elevation, partly in section, the tubular
steering fork standard and handle bar column and Figures 4 to 11 represent parts
of the said Figure 3 drawn to a larger scale.
The same letters of reference indicate the same parts in the several figures of
the drawings.
a is the tubular steering fork standard, the upper part of which is screwed at a²
and upon the said screwed part the screw nut b (shown separately in section_in
Figure 9) takes. In the top of the screwed part a² of the steering fork standard a
is a steel bush e shown separately in vertical and horizontal section respectively in
Figures 10 and 11. The said steel bush c is conical at top and bottom and is
provided with parallel slits 2 at top and parallel slits eat bottom, (the said slits
and breaking joint) so as to make the said steel bush e elastic. The bush e is
prevented from turning in the screwed part a² by inwardly projecting ribs a³ in
the said screwed part a² (see Figures 7 and 8) engaging with two of the parallel
slits in the bottom of the bush c. The screw nut is made taper or conical
internally to correspond with the elastic top of the steel bush c.
In order to adjust and fix the handle bar column d in the tubular steering fork
standard a the screw nut 6 is slightly withdrawn so as to relieve the handle bar
column d of the grip of the elastic top part of the steel bush c.
The steering
handle bar column d can now be raised or lowered to the desired height in the
steering fork standard a and refixed in its adjusted position by driving home the
screw nut . By the inner conical part of the screw nut b descending upon
the elastic slit top of the steel bush e the steering bar column d is effectually locked
in its adjusted position in the tubular steering fork standard a.
C
In order to provide for the lengthening or shortening of the brake rod on the
raising or lowering of the steering handle bar column d in the steering fork
standard a of the bicycle, we make the said brake rod telescopic. This part of
our invention is best illustrated in the detached views Figures 12, 13 and 14. The
upper part e of the said telescopic brake rod takes into the lower fixed tubular
parte. The top of the fixed part e2 is slightly conical and screwed and is pro-
vided with several parallel slits so as to give elasticity to it (see the separate view
Figure 13) and upon the conical elastic screwed top the screw nut f is screwed, the
interior of which is coned to take upon the conical elastic screwed top of the
tubular part e³. By slightly withdrawing the screw nut f and thereby relieving

page_text: the grip of the elastic top of the tubular part e on the sliding part e, the latter
part can be raised or lowered, thereby lengthening or shortening the telescopic
brake rod and by driving home the screw nut f the grip of the elastic conical top
of the tubular part 2 can be put upon the part e thus refixing the said part e of the
brake rod in its adjusted position.
In order to adjust the position of the abutment or collar g on the telescopic
brake rod e, e so as to put the required tension on the coiled spring of the brake
rod, we make the said abutment or collar free to slide on the tubular part e² of the
brake rod as illustrated in Figures 15, 16 and 17 and we provide the said collar or
abutment with a conical and slit screwed part upon which a screw nut i takes. By
driving home or relaxing the screw nut i the slit part of the collar g is made to
rod.
grip or release the tubular part e² of the telescopic brake reeering handle bar and
fixing it in its adjusted position is illustrated in Figure 3 and in the enlarged
detached views Figures 18, 19, 20 21 and 22; d is the steering handle bar having
brazed upon its middle the collar d³ provided with an annular groove k as seen in
Figures 19 and 20. On the top of the handle bar column d is an eye or perforated
lug forming a socket for the annular grooved collar d³. In this socket the
collar d³ can turn when the handle bar is unfastened as hereinafter described.
The lug has a vertical hole in which the lock pin m slides. The lower part of
the pin m is conical and flat preferably on one side, the upper cylindrical part
being screwed (see Figures 18 and 22). The said pin m, which is capable only of
a sliding motion, is raised or lowered by the collar screw nut n, which only has a
rotatory motion, the collar part n² of the said nut being inserted, by a horizontal
sliding motion, in the undercut recess in the lug l. Having turned the unfastened
handle bar d² into the desired angular position in the eye or lug the taper screw
pin m is put in its place in the vertical hole in the said lug, the flat face of the
screw pin being presented to the annular groove k in the collar d³ on the handle
bar. By rotating the collar screw nut n, the taper pin m is drawn into its raised
position, its taper and flat part being made to advance into the annular groove k
of the collar d³ thereby locking or binding the handle bar in its adjusted position.
By rotating the screw nut n in an opposite direction the screw pin m retires
from the groove k in the collar of the handle bar and the said handle bar is
unfastened.
The centre p³ on which the brake lever p turns is carried by the spring or elastic
clip p2 (see the enlarged sectional view Figure 23), the grip of the said clip on the
handle bar d being relaxed before the said handle bar can be turned or adjusted
and tightened after the adjustment of the said bar.
The clip p is fitted on the flanged bush or sleeve p brazed to the handle bar,
the said bush or sleeve turning in the clip on adjusting the angular position of the
handle bar.
The manner in which the sliding seat pillar is adjusted and fixed in the tubular
frame of the bicycle is illustrated in Figure 1 and the enlarged views Figures 24,25
and 26; Figures 24 and 26 representing elevations (partly in section) taken at
right angles to one another and Figure 25 a plan of our method of adjusting and
fixing.
On the tubular frame g of the bicycle is an elastic clips in which the seat pillar r
slides, by expanding or contracting which clip in the manner hereinafter described
the said seat pillar r may be released or gripped. On each side of the clip s is a
lug in which lugs are placed and fixed two screws t, 2, the screw t being right
handed and the screw being left handed. The right and left handed screw nut u
takes on the ends of the said screws t, t2. By turning the screw nut u in the
direction proper to cause the two screws t, to simultaneously approach one
another, the lugs s², s³ are drawn closer together and the clips is contracted and
made to grip or lock the seat pillar r to the frame 9. By turning the screw nut u
in the opposite direction so as to cause the two screws t, t to separate, the grip of
the clips on the seat pillar r is relaxed and the said pillar being unfastened may be

page_text: adjusted at any desired height and refixed in the manner before described.
When
the screw pins t, t2 are made tubular as represented in Figures 24 25 and 26, they
are prevented from rotating in their tubular and conical seats 3 by making a rib or
projection on the conical flange of the screw pin which takes into a groove or
depression in the conical scat of the lug as seen in Figure 24.
Our improvements in pedals for velocipedes are illustrated in the bicycle Figure 1
and in the detached views drawn to a larger scale in Figures 27, 28 and 29;
Figure 27 representing the pedal in front elevation, partly in section; Figure 28
the same in plan and Figure 29 the same in end elevation, partly in cross section.
According to our invention we provide the pedals with a rat trap foot tread vas
well as with an india rubber tread or pad w so that one or other may be used at the
will of the rider.
In making the combined pedal rest represented we take a plate v one edge of
which has the teeth forming the rat trap pattern and at right angles to this plate v
we fix a second plate 2 which is perforated at v³, v3 for carrying the india rubber
pad w. This compound pedal rest is fitted to the pedal end plates, and fixed by
screw nuts y, y in such a position that either the rat trap plate » can be used as the
foot rest by the rider as illustrated in dotted lines in Figure 27, or the india rubber
pad or tread w as illustrated in full lines in Figures 27 28 and 29. In Figure 28
one of the india rubber treads w is represented removed from its supporting
plate v².
The improvements which we have described and illustrated as applied to a safety
bicycle are applicable to velocipedes generally.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that
we claim as our invention of “ Improvements in bicycles tricycles and other
velocipedes ;-
