HENRY ALFRED SHELTON, 40, Redcliffe Road, Mapperley Road, Nottingham,
Engineer, do hereby declare the nature of this invention to be as follows:
According to this invention the saddle pillar is made in two parts, the one the
vertical part, which is attached to the frame of the machine, and the other the
horizontal part to carry the saddle.
The two parts are joined together by means of a tapered male and female joint,
and is locked in possition with a conical locking nut.
The horizontal part of pillar is bored at such an angle, that it will lie truly
horizontal whether placed fore or aft of the vertical part.
The horizontal part can be moved from or to its fore and aft possitions by remov-
ing the conical locking nut and turning the horizontal part over in its joint.
By arranging the parts as above described, a greater length of ajustment for
the saddle is obtained.

I, HENRY ALFRED SHELTON, of 40, Redcliffe Road, Mapperley Road, Nottingham,
do hereby declare the nature of this 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 relates to an improvement in that part of a cycle known as the
seat pillar.
These pillars are either direct or straight, or 7 shaped, with the horizontal
member directed either forwards or backwards, and are made adjustable vertically
by telescoping the vertical member into the seat tube or seat column of a cycle
framing.
The one or upright portion of the seat pillar is thus used for vertical adjust-
ment of the pin and saddle fixed thereon, whilst the horizontal portion is used
for adjustment of the attachment boss of the said saddle and its spring framing
along the same.
Some riders prefer to sit as far back as possible while others prefer the forward
position, and to meet this requirement, seat pillars are often made of a T shape
so that the saddle can be fitted either in front of or behind the upright limb of
12

page_text: The object of my invention is to provide a seat or saddle pillar which admits
of being converted into either a forward L-pin, a backward L-pin or a direct seat
pillar, according to the requirements of a rider, and this I effect by making the
saddle pillar of two detachably-connected parts, viz., a vertical part or member,
which is attached to the framing of a machine, and a horizontal part, to which the
saddle is secured and the position of which is capable of being reversed relative
to the vertical leg, or removed therefrom altogether, when necessary.
Figure 1 of the accompanying drawing represents a portion of a bicycle framing
fitted with a reversible or convertible seat pillar constructed according to my
invention. This view represents the horizontal limb or member, whereto the
saddle is secured, coming behind the vertical member, thus making a seat pillar
of the backward L type.
Figure 2 is a like view as Figure 1, but with the position of the horizontal
member of the L-pin reversed, so that it comes in front of the vertical limb and a
seat pillar of the forward L type.
Figure 3 is a further similar view to Figure 1, but showing the seat pillar con-
verted into the straight or direct type, with the attachment boss of the saddle
secured directly to the upper end of the vertical member.
Figure 4 is a side elevation upon an enlarged scale, of the seat pillar made up
in the backward L type.
Figure 5 is an end elevation of the same.
Figure 6 is a side elevation of the seat pillar with the horizontal member applied
to the vertical limb so as to make a forward L pin.
Figure 7 is a longitudinal vertical section of the said pin with the parts in the
same position as in Figure 6.
Figure 8 is a transverse vertical section of Figure 7 upon the dotted line x.
Figure 9 represents elevations of the dis-assembled component parts of my
improved seat pin or saddle pillar.
The same letters of reference indicate corresponding parts in the said Figures 1
to 9 of the drawings.
The improved saddle pin is made up of two parts or members, viz., the upright
leg a, the lower end of which takes into, and is secured to the frame of a cycle by
the seat lug c, and a horizontal member b, to which the saddle or seat d, is con-
nected by means of its attachment clip or boss d¹. These two parts are secured
together by means of a male and female joint, comprising socket 61, at the inner
end of the horizontal member b, adapted to take over the reduced upper end a¹,
of the vertical leg, with the lower edge of the said female socket abutting, when
in position, against the stop collar a². The socket or eye is cross bored at such an
angle relative to the rest of the limb b, that the said limb will lie in a perfect
horizontal plane, whether placed fore or aft of the vertical member a.
parts are secured together by a locking nut or cap e, screwing into the internally
wormed upper end a³, of the member a, and with the flange or annular collar e¹,
thereof, when screwed fully home, coming upon the top edge of the socket b¹,
whilst to prevent the parts rotating upon one another, gaps or recesses 63, in the
edges of the socket are provided to engage over key projections a*, from the stop
collar a³.
The two
To convert the saddle pillar from the backward L form shown in Figures 1
and 4, to the rearward L form as in Figures 2 and 6, the locking nut is screwed
out and the socket of the horizontal member lifted off the summit of the vertical
leg and then reversed or turned right over so as to bring that edge which is upper-
most in Figure 4, undermost. The female socket is then placed again onto the
male end of the vertical pillar and forced home, with the keep gaps in its edge
engaging with the key projections at, when it then lies forward of the vertical
pillar but still in the same horizontal plane, in which position it is retained by
replacing the lock nut.
In case a direct seat pillar is required, then the locking nut and horizontal leg

page_text: are removed altogether and the vertical member is used alone, with the attach-
ment boss of the saddle clipping the reduced upper end thereof.
Instead of the female part of the socketting joint being carried by the horizontal
member, it may be formed upon the summit of the vertical part, in which case,
the ends of the horizontal limb would form the male part of the joint; a locking
nut and means for preventing twisting of the one element within or upon the
other being provided as before.
Or the rotation of the one member upon the other may be prevented by forming
opposed flats on the socketting parts of the male and female joint, or both the
socketting parts may be of a square, angular or similar irregular cross section,
instead of being made the socket of a circular section as before described.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
First: A seat pillar for cycles, having a detachable and reversible or con-
vertible non-rotating horizontal member, socketting at its inner end onto or into
the vertical or upright member, substantially for the purpose set forth.
Secondly:-A seat pillar for cycles, having a detachable and reversible or con-
vertible non-rotating horizontal member, socketting at its inner end onto or into
the vertical or upright member, with the said members being secured together by
a locking nut or cap, substantially for the purpose set forth.
Thirdly: In cycle seat pillars of the kind referred to in the preceding claims,
preventing the rotation of the members upon one another by a key or key projec-
tions of the one part taking into or engaging with corresponding recesses or sink-
ings of the other part, substantially as described and set forth.
