Improvements in Supporting the Saddles of Bicycles, Tricycles,
and other Velocipedes.
I, LANCELOT HENRY ADDISON PERRY-KEENE, of No. 9, Weaman Street,
Birmingham, in the County of Warwick, Manufacturing Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention consists of the construction and arrangement or combination of
parts hereinafter described for supporting the saddles of bicycles, tricycles and
other velocipedes, the object of my invention being to facilitate the mounting of
the rider to his or her seat on the saddle.
In order that my invention may be the better understood I remark that
ordinarily the saddle is supported upon the horizontal arm of an L pin or T bar
fixed in the seat pillar tube of the bicycle frame at a height convenient for the rider
when propelling the bicycle. The said height is such that it does not permit the
rider to seat him- or her-self on the saddle without great effort and frequently
only after one or two unsuccessful attempts to mount the saddle.
My invention is especially useful for supporting the saddles of ladies' bicycles
and tricycles but is applicable to the supporting of the saddles of velocipedes
generally and has for its object to permit the saddle to be readily lowered to
facilitate the rider mounting the saddle the saddle being raised and automatically
fixed in its normal position, that is, at its riding height by a slight backward rising
motion of the rider's body when seated on the saddle.
In constructing a saddle support according to my invention I fix to the seat
pillar tube by means of a clamp or clip or otherwise, a frame having preferably a
nearly triangular figure in plan. To the said frame I joint preferably three short
arms or connecting links carrying the horizontal bar or tube to which the saddle
is clamped.
In the normal position of the parts, that is when the saddle is at riding height
the jointed arms or connecting links are vertical or nearly vertical and are pre-
served in that position by a lug on one arm engaging in a recess formed by an
overhanging part of the frame and a spring sliding bolt on the underside of the said
frame.
When it is desired to depress the saddle into a lower plane to facilitate mounting
the same the rider presses back the spring sliding bolt referred to and pushes the
saddle forward when the arms or connecting links referred to turn like the jointed
arms of a parallel ruler and bring the saddle into a position convenient for the
rider to seat him- or her-self upon. The rider by a back motion of the body
when on the saddle causes the saddle to rise until the lug hereinbefore referred to
on one of the jointed arms pressing back the spring sliding bolt bears against the
overhanging part of the frame when the spring sliding bolt shoots forward and
fixes the position of the saddle support.
Deted this Twenty-seventh day of May 1897.

I, LANCELOT HENRY ADDISON PERRY-KEENE, of Guest Street Engineering Works,
Guest Street, Hockley, Birmingham, in the County of Warwick (late of No. 9,
Weaman Street, Birmingham, aforesaid), Manufacturing Engineer, do hereby
declare the nature of my invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
My invention consists of the construction and arrangement or combination of
parts hereinafter described for supporting the saddles of bicycles, tricycles and
other velocipedes, the object of my invention being to facilitate the mounting of
the rider to his or her seat on the saddle.
In order that my invention may be the better understood I. remark that ordinarily
the saddle is supported upon the horizontal arm of an L pin or T bar fixed in the
seat pillar tube of the bicycle frame at a height convenient for the rider when pro-
pelling the bicycle. The said height is such that it does not permit the rider to
seat himself or herself on the saddle without great effort and frequently only
after one or two unsuccessful attempts to mount the saddle.
My invention is especially useful for supporting the saddles of ladies' bicycles
and tricycles but is applicable to the supporting of the saddles of velocipedes
generally and has for its object to permit the saddle to be readily lowered to
facilitate the rider mounting the saddle, the saddle being raised and automatically
fixed in its normal position, that is, at its riding height, by a slight backward
rising motion of the rider's body when seated on the saddle.
In constructing a saddle support according to my invention I fix to the seat
pillar tube by means of a clamp or clip or otherwise, a frame having preferably a
nearly triangular figure in plan. To the said frame I joint preferably three short
arms or connecting links carrying the horizontal bar or tube to which the saddle
is clamped.
In the normal position of the parts, that is, when the saddle is at riding height,
the jointed arms or connecting links are vertical or nearly vertical and are pre-
served in that position by a lug on one arm engaging in a recess formed by an
overhanging part of the frame and a spring sliding bolt on the underside of the
said frame.
When it is desired to depress the saddle into a lower plane to facilitate mount-
ing the same, the rider presses back the spring sliding bolt referred to and pushes
the saddle forward when the arms or connecting links referred to turn like the
jointed arms of a parallel ruler and bring the saddle into a position convenient
for the rider to seat him or her-self upon. The rider by a back motion of the
body when on the saddle causes the saddle to rise until the lug herein before
referred to on one of the jointed arms pressing back the spring sliding bolt bears
against the overhanging part of the frame when the spring sliding bolt shoots
forward and fixes the position of the saddle support.
Figures 1, 2 and 3 of the accompanying drawings represent in side elevation,
plan partly in section, and end elevation respectively, a velocipede saddle support
constructed according to my invention in its normal or raised position and Figure 4
represents the same in its lowered position for facilitating the mounting of the
saddle of the velocipede.
Figures 5, 6 and 7 represent a modified arrangement of my invention herein-
after described.

page_text: The same letters of reference indicate the same parts in the several figures of
the drawings.
I will first describe the arrangement Figures 1, 2, 3 and 4.
a is the seat pillar tube having fixed to it at top the triangular base plate b.
To the said base plate a horizontal tube or bar c, to which the velocipede saddle is
to be fixed, is connected by jointed parallel links d, d, d' so that it may be raised
and lowered parallel to the base plate b. The parts are preserved in their raised
position by a spring pressed bolt e, engaging, when the parts are in the position
Figure 1, in a depression in a lug on the lower end of the front link d¹.
C
When the rider wishes to mount the saddle it is only necessary to press the
horizontal tube or bar c forward, after having withdrawn the spring pressed bolt a
when the links d, d, d¹ turning on their joints the parts of the saddle support take
the position Figure 4, a position convenient for the rider to seat him- or her-self
on the saddle. When the rider is seated on the saddle he or she may by a slight
rising and backward motion of the body cause the saddle to take its raised position
again, the bolt a snapping into its notch in the lug of the front link and pre-
serving the raised position of the parts.
Figures 5 and 6 represent in side and end elevation respectively a modified
saddle support, the parts being in their raised positions and Figure 7 represents an
elevation, partly in section, with the parts in their lowered positions.
In this arrangement the triangular base plate is dispensed with, two horizontal
parallel tubes c¹, c² being employed, the lower tube c² replacing the triangular base
plate in the first described arrangement. The two back connecting links d, d
are situated on opposite sides of the two tubes respectively and the front connect-
ing link passes through slots in the underside and upperside respectively of the
top and bottom tubes e, ². The parts are preserved in their raised position by
a strong coiled spring f within the base tube c² one end of which spring bears
against a fixed block within the tube 2 and the other end bears against a
plate c working within the tube c². The plate e seats itself against a square part
of the pin by which the links d, d are jointed to the tube c².
9
Further backward
movement of the saddle support is prevented by the link seating itself against
the end of the slot 5, see Figure 5.
When the saddle supporting tube c¹ is pressed forward for lowering the saddle
one of the angles of the square pin g presses against the plate 4 and compresses the
coiled spring f until the angle has passed the centre of the pin, when the back
action of the spring causes the plate to maintain the tube in its lowered posi-
tion while the rider seats him or her-self on the saddle. The action of this
modification is in all essential respects the same as that first described.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention:-
―
First; The combination in a bicycle, tricycle or other velocipede of an arrange-
ment of parallel jointed links under the saddle, constituting with the saddle bar
or tube, a rising and falling saddle support, the said jointed links when brought
into a horizontal or nearly horizontal position lowering the saddle and when
brought into a nearly vertical position raising the saddle substantially as and for
the purpose hereinbefore described and illustrated in the accompanying
drawings.
-
Secondly; The arrangement or combination of the parts of saddle supports for
velocipedes herein before described and illustrated in the accompanying drawings,
he said combination or arrangement of parts consisting essentially of a base bar,
olate or tube fixed to the top of the seat pillar tube of the velocipede and a second
and parallel bar or tube connected to the base bar, plate or tube by parallel jointed
inks substantially as and for the purpose herein before described and illustrated.
Thirdly; The combination with a saddle support of the kind claimed in the

page_text: foregoing claims of a spring bolt situated on the base plate for engaging or snap-
ping in a notch in one of the jointed parallel links when the parts are in their
raised position substantially as hereinbefore described and illustrated in
Figures 1, 2, 3 and 4 of the accompanying drawings.
Fourthly; The combination with a saddle support of the kind claimed in the 5
prior claims of a strong coiled spring situated in the base tube and bearing at one
end against a plate supported by the square point of one of the pins of the parallel
jointed connecting links substantially as hereinbefore described and illustrated in
Figures 5, 6 and 7 of the accompanying drawings.
Dated the Twenty-first day of March 1898.
