PROVISIONAL SPECIFICATION.
Improvements in Safety Bicycles, Tricycles, and other Velocipedes.
I JOHN SHARPE WILBRAHAM EDMUNDS of Sheepcote Street Birmingham
in the County of Warwick, Manufacturer do hereby declare the nature of this
invention to be as follows:-
My invention has reference to the parts by which the saddle or seat of the
safety bicycle, tricycle or other velocipede is connected to the body or frame of
the vehicle and has for its object principally to prevent the said saddle or seat from
inclining either to the right or left should the fixing screw become loose and thereby
prevent accident to the rider.
My invention has further for its object to prevent the support of the saddle or
seat from turning in the saddle post or other part of the vehicle in which it may
be inserted.
I will describe my invention in connection with a safety bicycle.
In the ordinary method of supporting the saddle or seat of a safety bicycle the
L pin is made of a cylindrical bar of steel or iron, a cylindrical eye or socket
on the foundation of the saddle taking on the horizontal branch of the said _ pin,
the vertical arm of the said L pin, entering the tubular saddle post. The saddle.
is fixed by a fixing screw on the eye or socket and a fixing screw on the saddle
post. In consequence of the cylindrical figure of the pin and of the eye or
socket and saddle post the saddle or seat can turn aside and the
the saddle post should the said fixing screws become loose.
pin swivel in
In order to prevent the motions described while permiting of a free sliding
motion of the parts for giving the required adjustments I form the eye or socket
on the foundation of the saddle with an internal projection or rib and I form a
longitudinal groove in the horizontal branch of the L pin of a size and shape
suitable for the said projection in the eye to engage and slide in. I also form
a similar projection on the interior of the saddle post and form a similar groove
on the vertical branch of the L pin. By this construction the saddle or seat is
capable of adjustment in the ordinary way but is incapable of the objectionable
motions inseparable from the ordinary construction.
Although I prefer the use of the projections and slots I have described yet
I do not limit myself thereto as the same effect may be produced by making
the eye or socket and the horizontal branch of the L pin square or triangular
in cross section or of such other figure that while the said eye or socket is
capable of sliding freely on the L pin it is incapable of turning thereon.
Similarly the vertical branch of the pin and the interior of the top of the
saddle post may be made square, triangular or of such other figure that the
Lpin while capable of sliding freely in the saddle post is incapable of turning
therein.
The application of my invention to tricycles and other velocipedes differs
in no essential respect from its application to a safety bicycle as hereinbefore
described.

Improvements in Safety Bicycles, Tricycles, and other Velocipedes.
I JOHN SHARPE WILBRAHAM EDMUNDS, of Sheepcote Street, Birmingham
in the County of Warwick Manufacturer, do hereby declare the nature of my.
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has reference to the parts by which the saddle or seat of the
safety bicycle, tricycle or other velocipede is connected to the body or frame of
the vehicle and has for its object principally to prevent the said saddle or seat from
inclining either to the right or left should the fixing screw become loose and
thereby prevent accident to the rider. My invention has further for its object to
prevent the support of the saddle or seat from turning in the saddle post or other
part of the vehicle in which it may be inserted.
I will describe my invention in connection with a safety. bicycle.
In the ordinary method of supporting the saddle or seat of a safety bicycle
the pin is made of a cylindrical bar of steel or iron, a cylindrical eye or
socket on the foundation of the saddle taking on the horizontal brauch. of the
said pin, the vertical arm of the said pin entering the tubulars saddle post.
The saddle is fixed by a fixing screw on the eye or socket and a fixing screw on
the saddle post. In consequence of the cylindrical figure of the pin and
of the eye or socket and saddle post, the saddle or seat can turn aside .and
the pin swivel in the saddle post should the said fixing screws become loose.
In order to prevent the motions described while permitting.ofa. free sliding
motion of the parts for giving the required adjustments I form the eye or socket
on the foundation of the saddle with an internal projection or rib. and, I form a
longitudinal groove in the horizontal branch of the L pin of a size. and shape
suitable for the said projection in the eye to engage and slide in. I also form a
similar projection on the interior of the saddle post and form a similar: groove on
the vertical branch of the pin. By this construction the saddle or seat is capable
of adjustment in the ordinary way but is incapable of the objectionable. motions
inseparable from the ordinary construction.
Although I prefer the use of the projections and slotst I have described yet I
do not limit myself thereto as the same effect may be produced by making the eye
or socket and the horizontal branch of the Lpin square or triangular in cross sectiou
or of such other figure that while the said eye or sooket is capable of sliding freely
on the pin it is incapable of turning thereon. Similarly the vertical branch of
the pin and the interior of the top of the saddle post may be made. square,
triangular or of such other figure that the L pin while capable of sliding freely in
the saddle post is incapable of turning therein.
Figure 1, of the accompanying drawing represents in side elevation, the saddle
of a safety bicycle connected to the L pin on the body of the vehicle according to
my invention;
Figure 2 represents in longitudinal section; Figure 3 in cross section and
Figure 4 in plan of upper side the L pin and saddle socket drawn to a larger scale.
The same letters of reference indicate the same parts in Eigures 1, 2, 3 and 4.
a is the saddle of the safety bicycle and is the socket fixed to the supporting
frame c of the saddle in the ordinary way; d, d² is the L pin, the vertical, part 2
of which works in the tubular seat or saddle post of the bicycle. The saddle is
connected to the horizontal branch d of the L pin by sliding the socket 6 upon the
said branch d and fixing it thereon by driving home the clamping screw è of the
Baid socket.
For the purpose of preventing the saddle from inclining either to the right hand
or left should the fixing or clamping screw e become loose, I make along the
upper part of the horizontal branch d of the L pin, a ✓ shaped groove or

page_text: slot and I.fix. at the inside and. between the two eyes of the socket a V shaped
projection or rib g of a size proper for the V shaped groove to take upon as
represented. in the enlarged views Figures 2, 3 and 4. After. the projection on
the socket has by a sliding motion been engaged with the groove f in the Lpin
the socket is fixed by driving home the clamping screw e and the saddle is thereby
connected to the L pin. Should the fixing or clamping screw. e..accidentally
become loose, the inclining of the saddle or seat to the right or left on the
horizontal branch of the L pin is prevented by the connection described and
represented of the saddle socket with the said branch of the L pin. and accident to
the rider is thereby avoided.
"The positions of the engaging parts of the L pin and socket may be reversed ;
that is, the V shaped groove may be made in the socket and the V shaped projection
on the underside of the horizontal branch of the L pin.
This modification is represented in elevation, partly in section in Figure 5 and
cross section in Figure 6 where the V shaped slot in the socket b is marked h
and the V shaped projection on the horizontal branch d of the L-pin-is marked i.
In Figure 5 I have represented the inclined branch d² of the pin so engaged
with the mouth of the seat post that the former cannot turn in the latter, the said
arrangement resembling that represented in Figures 1, 2, 3 and 4 for preventing
the inclination of the saddle upon the horizontal branch of the L pin. A cross
section of the tubular seat post and inclined branch of the pin is represented
in Figure 7. In Figures 5 and 7, the tubular seat post is marked and has
in its interior, for a short distance, a ✓ shaped projection upon which the
V shaped groove m in the branch d² of the L pin engages when the latter is by
a sliding motion passed into the seat post.
l
The groove may be made in the collar end of the seat post and the projection
on the inclined or vertical branch of the L pin, but I prefer the arrangement
represented in Figures 5 and 7. Or the vertical or inclined branch of the L pin
may be prevented from turning in the seat post while capable of sliding freely in
the said post, by making the said branch of an angular figure in cross section and
the socket of a corresponding figure in cross section.
Figure 8 represents a portion of the vertical or inclined branch p of the
Lpin made of a hexagonal figure in cross section and
Figure 9 represents in longitudinal section the head end of the seat post
made of a corresponding figure in cross section to receive the hexagonal branch
of the L pin.
P
Instead of making the engaging parts of the L pin and seat post hexagonal
in cross section they may be square or triangular or elliptical in cross section.
The arrangements last described and represented for preventing the turning of
the vertical or inclined branch of the L pin in the seat post, may be applied to the
connection of the saddle to the horizontal branch of the L pin. That is to say,
the horizontal branch of the pin may be made of a square or other angular figure
or of an elliptical figure in cross section and the socket on the saddle have a corre-
sponding figure in cross section for passing onto the said angular or elliptical
horizontal branch of the L pin.
The application of my invention to tricycles and other velocipedes differs in no
essential respect from its application to a safety bicycle as herein before described
and illustrated in the accompanying drawing.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I
claim as my invention of "Improvements in safety bicycles, tricycles and other
velocipedes":
First Preventing the saddle or seat of the velocipede from turning on the
horizontal branch of the L pin so that the said saddle or seat is incapable of
inclining either to the right or left by making a groove or depression in the said
horizontal branch of the L pin and an internal projection in the socket on the
:

page_text: foundation of the saddle for engaging with the said groove in the ☐ pin; or making
a groove in the socket and a projection on the L pin for the same purpose;
or making the horizontal branch of the pin square or of other angular figure or
of an elliptical figure in cross section and making the saddle socket of a corre-
sponding angular or elliptical figure in cross section for the same purpose substantially
as hereinbefore described and illustrated in the accompanying drawing.
Secondly-Preventing the vertical or inclined branch of the L pin from turning
in the seat or saddle post or other part of the vehicle in which it may be inserted,
by a projection and groove or by making the engaging parts of a square or angular
figure or of an elliptical figure in cross section substantially as herein before described
and illustrated in the accompanying drawing.
