COMPLETE SPECIFICATION.
Adjusting Device for Bicycle Saddles.
I, JAMES GRIEVE LORRAIN, M. Inst. E.E., M.1. Mech. E. of Norfolk House,
Norfolk Street, Strand, London, W.C. in the County of Middlesex, Chartered
Patent Agent, do hereby declare the nature of this invention (as communicated
to me from abroad by Alexander P. O'Hara, of 48 South Canal Street Chicago,
in the County of Cook and State of Illinois, United States of America, Gentleman,)
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 certain improvements in a device capable of being
secured in position upon the supporting frame post of a bicycle or other analogous
vehicle which device is adapted to hold or support the saddle or seat of the
bicycle upon the frame.
One of the primary objects of my invention resides in the provision of means
whereby the saddle or seat may be readily and conveniently adjusted at any
desired angle and maintained and firmly held in such adjusted position under the
severe strain and stress imposed upon the connection by virtue of the superimposed
weight of the rider and the shocks incident to propulsion and irregularities of
roadway.
My invention has certain other objects in view and consists in certain features
about to be particularly described and pointed out in my claims, reference being now
had to the accompanying drawings in which:
Figure 1 is a side elevation of a bicycle saddle or seat showing the upper portion
of the frame post and connecting and adjusting device for the saddle, which latter
is adjusted in an angular position.
Figure 2 is a plan view of the upper side of a portion of the spring support
showing the manner of attaching the connecting and adjusting device.
Figure 3, is a vertical longitudinal central section through the connecting and
adjusting device.
Figure 4 is a rear view of the connecting and adjusting device.
In the use of a bicycle the rider frequently desires to change the angle of the
seat or saddle.
It is desirable that this angular adjustment may be accomplished readily and
conveniently without the exercise of skill, the use of a tool or the exertion of
much strength. It is also desirable that means shall be afforded whereby the
rider may obtain a wide range of angular position and also effect minute inter-
mediate adjustments to suit the various requirements of the rider. It is necessary
that when the desired adjustment or position is attained that then the parts may
be securely locked and held against movement under the severe strain arising from
shocks of propulsion and irregularity of roadway.
In carrying out my invention I provide a frame post clamping member A,
through which the upper end portion of the frame post B passes and in which it
is firmly held by means of the set screw a in the usual manner., Secured to the
saddle D is a spring support D 2, which spring support is longitudinally slotted.
Pivoted or hinged to one of the upper corners of the clamping member A is an
adjusting screw E, the upper end portion of which passes loosely through a
slightly elongated slot in the spring support D 2, indicated more clearly at d by
the dotted lines in Figure 2.
Mounted upon the screw thread of the adjusting screw E and respectively

page_text: above and below the spring support D2 are the fastening thumb wheels E2
and E 3.
As shown in Figure 1 the saddle is adjusted at an angle and held in that
position and in order to effect any other desired angularity of position it is simply
necessary to operate the fastening thumb wheels E2 and E3 by screwing the
same up or down upon the adjusting screw E and when the desired angular
position is obtained then screwing the two said fastening thumb wheels tightly
against the spring support D2 thus tightly, securely and firmly locking the
saddle D in its adjusted position and holding the same in that position rigidly under
all sorts of strain and shock encountered in riding.
One of the features of my device incidentally accomplished, is the reduction of
the distance between the saddle and the supporting post of the bicycle frame upon
which it is mounted, thereby permitting the attachment of this adjusting and
connecting device to any bicycle without increasing the distance between the saddle
and the pedal.
It will also be observed by reference to the drawings that the clamping member
is also held on the spring support by means of a hinged stud H which is screw
threaded to receive the binding nut H 2.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. An adjusting device for bicycle saddles or seats consisting of an intermediate
member clamped upon the bicycle frame post, an intermediate support secured to
the saddle and a pivoted or hinged connection between the intermediate member
clamped to the frame post together with adjusting and holding devices secured
to the intermediate clamping member and adjustably secured to the intermediate
support.
2. An adjusting device for bicycle saddles or seats consisting of an inter-
mediate member clamped upon the bicycle frame post, an intermediate support
secured to the saddle and a pivoted or hinged connection between the intermediate
support and the intermediate member clamped to the frame post together with
adjusting and holding devices pivoted or hinged to the intermediate clamping
member and adjustably secured to the intermediate support.
3. An adjusting device for bicycle saddles or seats consisting of an intermediate
member clamped upon the bicycle frame post, a spring support secured to the
saddle to which the intermediate clamping member is pivoted or hinged and an
adjusting screw hinged to the intermediate clamping member and adjustably
secured to the spring support by means of locking thumb wheels movable along
the adjusting screw.
4. An adjusting device for bicycle saddles or seats consisting of an intermediate
member clamped upon the bicycle frame post, a spring support secured to the
saddle to which the intermediate clamping member is pivoted or hinged and an
adjusting screw also pivoted or hinged to the intermediate clamping member and
adjustably secured to the spring support by means of locking thumb wheels movable
along the adjusting screw.
