Improvements in Attaching and Adjusting the Saddles of Bicycles,
Tricycles, and other Velocipedes.
We, JAMES ALFRED LAMPLUGH, of No. 135 Great Colmore Street,
Birmingham, in the County of Warwick, Manufacturer, and SYDNEY AUGUSTUS
LAMPLUGH, of No. 1 Charlotte Road, Birmingham, aforesaid, Manager of Works
do hereby declare the nature of this invention to be as follows:-
Our invention consists of the arrangements or combinations of parts hereinafter
described for attaching and adjusting the saddles of bicycles, tricycles and other
velocipedes.
We will describe our invention in connection with a safety bicycle.
On the summit of the saddle pillar tube we place a divided cap cylindrical
within and conical without. A central hole is made in the said divided cap
tbrough which a headed screw pin passes. Fitting upon the said divided conical
cap is a socket cylindrical without and conical within. The interior of the said
socket having the same inclination as the exterior of the divided conical cap.
The summit of the said socket is concave and the convex under side of the
lower half of a divided grip consisting of two gripping plates rests and works in
the concavity in the said socket, the under surface of the said gripping plate
having a convexity of the same radius as the concavity in the summit of the
socket. The upper gripping plate is convex on its upper side and upon the said
convex upper side the concave lower face of a tubular piece or small socket bears.
The screwed end of the headed screw pin described passes through the last named
small socket and by means of a screw nut working thereon the said headed screw
pin can be drawn upwards with any required degree of force. As the said screw
pin rises it draws up the divided conical cap described which is thereby wedged
between the saddle pillar tube and the cylindrical socket on the said divided
conical cap. The said socket is thereby fixed to the saddle pillar tube with any
required degree of tightness. By the same action of the headed screw pin, the
gripping plates or the two parts of the grip are made to approach each other and
to close tightly upon the wire foundation of the saddle. Those parts of the said
wire foundation which are situated between the gripping plates are made square or
angular in cross section and fit in corresponding recesses in the gripping plates.
Lateral twisting of the saddle is thereby prevented.
The inclining or tilting of the saddle to any required angle is effected by relaxing
the screw nut and raising or lowering the front end of the saddle.
The convex
faces of the gripping plates travel through the required angle and the tightening
of the screw nut fixes them and the saddle at the inclination to which it has been
adjusted.
Or in place of the headed screw pin, the divided conical cap and the socket
described a screw pin having a cross tubular piece at its lower end may be
employed the said cross tubular piece being fixed in the saddle pillar tube by a
cross headed screw pin and nut, the said screw pin passing through the cross
tubular piece.
In securing a saddle to the horizontal branch of an L pin we adopt the following
arrangement of parts.
We make a divided clip one half of which is situated on the upper side and the
other half on the under side of the L pin. At the sides of the upper half are
curved grooves in which curved parts of the wire foundation seat themselves and
the two halves of the grip are drawn together by means of screw pins the heads

page_text: of the said screw pins being formed into loops or eyes through which the parallel
branches of the wire foundation pass. When the parts are in position screw nuts
on the lower ends of the screw pins described are screwed upon the said lower
ends of the screw pins. The two halves of the clip are thereby tightened upon
and made to grip the horizontal arm of the L pin and the curved parts of the wire
foundation and at the same time fixed firmly in the curved recesses in the upper
half of the divided clip.
The edges of the upper clip bear only at their ends on the edges of the lower
clip so that there is a slight elasticity in the said edges and the screw nuts can be
screwed further home after they bind on the pin and all the parts are thus
simultaneously bound tightly together.

Improvements in Attaching and Adjusting the Saddles of Bicycles,
Tricycles, and other Velocipedes.
We JAMES ALFRED LAMPLUGH of No. 135 Great Colmore Street, Birmingham
in the County of Warwick, Manufacturer and SYDNEY AUGUSTUS LAMPLUGH,
of No. 1. Charlotte Road Birmingham, aforesaid, Manager of Works 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 consists of the arrangements or combinations of parts hereinafter
described for attaching and adjusting the saddles of bicycles, tricycles and other
velocipedes.
We will describe our invention in connection with a safety bicycle.
On the summit of the saddle pillar tube we place a divided cap cylindrical
within and conical without. A central hole is made in the said divided cap
through which a headed screw pin passes. Fitting upon the said divided conical
cap is a socket cylindrical without and conical within, the interior of the said
socket having the same inclination as the exterior of the divided conical cap.
The summit of the said socket is concave and the convex under side of the
lower half of a divided grip, consisting of two gripping plates, rests and works in
the concavity in the said socket, the under surface of the said gripping plate
having a convexity of the same radius as the concavity in the summit of the
socket. The upper gripping plate is concave on its upper side and upon the said
concave upper side the convex lower face of a tubular piece or small socket bears.
The screwed end of the headed screw pin described passes through the last named
small socket and by means of a screw nut working thereon the said headed screw
pin cau be drawn upwards with any required degree of force. As the said screw
pin rises it draws up the divided conical cap described which is thereby wedged
between the saddle pillar tube and the cylindrical socket on the said divided
conical cap. The said socket is thereby fixed to the saddle pillar tube with any
required degree of tightness. By the same action of the headed screw pin, the
gripping plates, or the two parts of the grip, are made to approach each other and
to close tightly upon the wire foundation of the saddle. Those parts of the said
wire foundation which are situated between the gripping plates are made square
or angular in cross section and fit in corresponding recesses in the gripping plates.
Lateral twisting of the saddle is thereby prevented.
The inclining or tilting of the saddle to any required angle is effected by
relaxing the screw nut and raising or lowering the front end of the saddle. The
faces of the gripping plates travel through the required angle and the tightening

page_text: been adjusted.
Or in place of the headed screw pin, the divided conical cap and the socket
described, a screw pin having a cross tubular piece at its lower end may be
employed, the said cross tubular piece being fixed in the saddle pillar tube by a
cross headed screw pin and nut, the said screw pin passing through the cross tubular
piece.
In securing a saddle to the horizontal branch of an L pin we adopt the following
arrangement of parts.
We make a divided clip, one half of which is situated on the upper side and the
other half on the under side of the L pin. At the sides of the upper half are
curved grooves in which curved parts of the wire foundation seat themselves and
the two halves of the grip are drawn together by means of screw pins the heads
of the said screw pins being formed into loops or eyes through which the parallel
branches of the wire foundation pass. When the parts are in position, screw nuts
on the lower ends of the screw pins described are screwed upon the said lower
ends of the screw pins. The two halves of the clip are thereby tightened upon
and made to grip the horizontal arm of the L pin and the curved parts of the
wire foundation are at the same time fixed firmly in the curved recesses in the
upper half of the divided clip.
The edges of the upper clip bear only at their ends on the edges of the lower
clip so that there is a slight elasticity in the said edges and the screw nuts can be
screwed further home after the half clips bind on the pin and all the parts are
thus simultaneously bound tightly together.
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 and Figure 2 in plan, a portion of the wire
foundation of a velocipede saddle connected to the summit of the saddle pillar
tube of the velocipede by the arrangement herein first described; Figures 3
and 4 represent vertical sections of the same taken in planes at right angles to one
another; Figures 5, 6 and 7 represent detached parts of the same as hereinafter
described.
The same letters of reference indicate the same parts in the several figures of
the drawings.
a is the saddle pillar tube of the velocipede and b is the wire frame or foundation
of the saddle; c, c is the divided cap placed on and bound to the summit of the
saddle pillar tube a. The said divided cap c is represented separately in section
and plan in Figure 5. It will be seen that the said cap is cylindrical within and
conical without, and has a central hole d at top through which the headed screw
pin e passes; is the socket fitting upon the said divided cap i. This socket is
shown separately in section and plan in Figure 6. The said socket is cylindrical
without and conical within, the conical interior of the said socket, having the same
inclination as the conical exterior of the divided_cap c, c as seen in the section
Figure 3 and the separate parts Figures 5 and 6. The summit of the socket f is
concave and serves as a seat for the lower gripping plate; g, h are the gripping
plates, or the divided grip, between the opposed faces of which the wire frame or
foundation of the saddle is gripped. The lower face of the bottom gripping
plate is convex and is fitted and works in the concavity at the summit of the
socket f, the lower face of the said gripping plate h having a convexity of the same
radius as the said summit of the socket as will be best seen by referring to the
section Figure 3 and the separate view Figure 7. The upper gripping plate g is
concave on its upper face at g² and upon the said concave face g' the convex
lower face of the tubular part or socket piece i bears. The screwed end of the
headed screw pin e passes through the said socket piece i and by means of the
screw nut k the screw pin e can be drawn upwards with any required degree of
force, the head of the screw pin bearing against the underside of the nearly
closed top of the divided cap c (see Figure 3). The opposed faces of the two

page_text: gripping plates 9, h are provided with semi-circular grooves for taking upon or
enclosing and gripping the wire foundation of the saddle. Or the grooves in
the opposed faces of the gripping plates g, h may be made square or angular in
cross section and the wire foundation have a corresponding figure. By this means
lateral twisting of the saddle is prevented.
In securing the saddle frame or foundation to the clip and the latter to the
saddle pillar tube, the wires of the saddle foundation are placed in the grooves of
the lower gripping plate hand the upper gripping plate g is placed thereon and
the socket piece i fitted in its place upon the upper gripping plate g. The screw
nut being placed on the screwed end of the headed screw pin e, the said screw nut
is rotated and made to bear against the socket piece i so as to draw the screw
pin e upwards. As the said screw pin rises it draws up the divided cap c which is
thereby wedged between the saddle pillar tube a and the socket f on the said cap
as will be understood by an examination of Figure 3. By this means the socket f
carrying the divided grip or gripping plates g, h is securely fixed to the saddle
pillar tube. By the same action of the headed screw pin e, the gripping plates
are made to approach each other and close tightly upon the wire foundation b of
the saddle and bind it firmly in its place (see Figures 1, 3 and 4) on the saddle
pillar tube. In order to tilt or incline the saddle it is only necessary to relax the
screw nut and raise or lower the front end of the saddle as indicated in dotted
lines in Figure 3. As the saddle is tilted or inclined the convex face of the lower
gripping plate and the concave face of the upper gripping plate bearing
respectively against the correspondingly shaped faces of the socket and socket
piece f,i, travel through the required angle and the tightening of the said screw
nut k refixes the said gripping plates and secures the saddle at the inclination to
which it has been adjusted.
Figure 8 represents in side elevation; Figure 9 in plan and Figures 10 and 11
in vertical section (taken in planes at right angles to one another) the saddle
foundation fixed to the clip and the latter to the saddle pillar post by a modified
arrangement.
In this arrangement the divided conical cap and socket are dispensed with
and in place of the screw pin e, a screw pin k having a cross tubular piece k² at its
end is used for fixing the clip to the saddle pillar post, the said screw pin being
secured to the pillar post by a cross_screw pin 7 passed through the tubular
piece and fixed by the screw nut 12. The upper and lower gripping plates g, h
and the convex socket piece i and the head of the saddle pillar tube are constructed
substantially as in the first described arrangement and their action is the same.
That is to say, by relaxing the screw nut 3 by which the two gripping plates g, h
are made to grip the wire foundation 6 of the saddle, the said saddle can be
inclined or tilted to the desired angle by the movement of the two gripping plates
between the curved seats of the saddle pillar tube a and socket piece i, and the
adjusted saddle refixed by driving home the screw nut k³.
Figure 12 represents in side elevation; Figure 13 in longitudinal section;
Figure 14 in end elevation and Figure 15 in cross section, a clip constructed
according to our invention for securing a saddle to the horizontal branch of
the pin of a velocipede.
m, n are the two parts of the divided clip, the upper half m being situated on
the upper side and the lower half n on the underside of the L pin marked p.
The sides of the upper half clip m are provided with curved grooves (see Figure 13)
for the curved parts
of the saddle foundation to seat themselves in. The two
nuts 8, s.
half clips. m, n are drawn together by loop headed screw pins r, r and screw
The loops of the screw pins r, rare situated at the middles of the
curved seats in the upper half clip m and through the said loops the parallel
branches q, q of the wire foundation of the saddle are passed as represented.
When the curved branches of the wire foundation are in position in the eyes of
the screw pins r, r and the two halves m, n of the clip have been made to embrace
pin p, the screw nuts s, s on the ends of the screw pins r, r are screwed upon
the

page_text: the said pins. The halves m, n of the clip are thereby tightened upon and made
to grip the horizontal arm of the L pin and the curved parts of the wire
foundation of the saddle are at the same time fixed firmly in the curved recesses in
the upper half of the clip as will be understood by an examination of the
drawings.
It will be seen by reference to Figure 14 that the edges of the upper half
clip m bear only at their ends on the edges of the lower half clip n so that there is
a slight elasticity in the said edges. This construction permits of the screw
nuts s, s being screwed further home after the half clips bind on the L pin so
that all the parts are simultaneously bound together.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed, we declare that we claim as our
invention;
First. The construction and combination of parts hereinbefore described and
illustrated in Figures 1 to 7 both inclusive of the accompanying drawings for
attaching velocipede saddles to and adjusting them upon the summits of the saddle
pillar tubes of the said velocipedes; that is to say, the combination of the socket f,
having a concave seat, and the socket piece i having a convex seat, with the two
parts g, h of the divided grip baving curved outer bearing faces corresponding in
figure with and working between the said concave and convex seats for the
purpose of permitting of the inclining or tilting of the saddle to any required
angle, together with the divided cap cand central screw pin e for simultaneously fixing
the socket to the saddle pillar tube and binding the parts of the divided grip
upon the wire foundation of the saddle the several parts being constructed,
arranged and acting substantially as described and illustrated.
Secondly. The modification hereinbefore described and illustrated in Figures 8,
9, 10 and 11 of the accompanying drawings in which the vertical screw pin of the
clip is fixed to the saddle pillar tube by a cross tubular piece on the lower end of
the said pin and a cross screw pin and screw nut in place of the externally conical
divided cap and internally conical socket referred to in the first claim.
Thirdly. The construction and combination of the parts herein before described
and illustrated in Figures 12, 13, 14 and 15 of the accompanying drawings of a
clip for securing the saddle to the horizontal branch of the pin of the
velocipede and the wire foundation of the saddle to the clip.
