PROVISIONAL SPECIFICATION.
Sliding or Rolling Attachment for Seats of Bicycles, Tricycles, and
the like.
I, WILLIAM STEWART, Clerk, of 35, Graham Street, Govan, in the County of
Lanark, Scotland, do hereby declare the nature of this invention to be as follows
-
It consists essentially of an attachment for cycle seats, constructed so as to
allow the seat to move backward and forward by the pressure of the rider
In carrying out the invention I employ a double bracket or carrier, formed
preferably of two narrow strips of metal turned up at the ends and held in position
by an axle at each end The sides of this bracket or carrier are provided with
a number of holes placed directly opposite to each other, by which means the
arat post may be fixed in any desired position On each axle I mount a roller,
over which rollers I pass an endless flexible band of any suitable material, such
as leather, canvas, and the like On the upper side of this band I fix a clamp
of any known pattern To this clamp the seat is attached in the usual manner
In lieu of the bracket and seat post I may use two uprights attached to tho
cycle frame.
Also, I may substitute for the rollers and endless band, one or more strips of
metal attached to each end of the bracket or carrier, or to each upright: I then
use a special flanged clamp constructed with rollers so that it may travel backward
and forward on the strip or strips
Further, the carrier may consist of one or more rails formed of any desired
shape, either flat, round or tubular
Also, the seat clamp may be constructed either with planed surfaces to slide
on the bracket or carrier, or with rollers or wheels to roll on the bracket or
carrier
If desired, the uprights may be fixed to each end of the crossbar of the seat
post, instead of to the frame of the cycle

Sliding or Rolling Attachment for Seats of Bicycles, Tricycles, and
the like.
I, WILLIAM STEWART, Clerk, of 35, Graham Street, Govan, in the County of
Lanark, Scotland, 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..
-
This invention has for its object to produce an attachment for the seats of
cycles, by means of which the seat may be moved backward and forward instea:l
of being fixed as hitherto

page_text: To carry out my invention I employ a double bracket or carrier, formed prefer-
ably of two nallow strips of metal turned up at the ends and held in position by an
axle at each end. The sides of this bracket or care are provided with a number
of holes placed duectly opposite to each other, by which means the seat post
may be fixed in any desired position On each axle 1 mount a roller, over which
rollers I pass an endless flexible band of any suitable material, such as leather,
canvas, and the like On the upper side of this band I fix a clamp of any known
pattern. To this clamp the seat is attached in the usual manner.
In lieu of the bracket and seat post I may use two uprights attached to the
cycle fiame
Also, 1 may substitute for the rollers and endless band, one or more strips of
metal attached to each end of the bracket or carrier, or to each upright I then
use a special flanged clamp constructed with rollers so that it may travel backward
and forward on the strip or strips
Further, the carer may consist of one or more rails formed of any desired
shape, either flat, round, or tubular
The
Also, the seat clamp may be constructed either with planed surfaces to slide on
the bracket or caue, or with rollers to roll on the bracket or carrie
Eaid olleis may be provided with ball bearings.
If desired, the uprights may be fixed to each end of the crossbar of the seat
post, instead of to the frame of the cycle
01, I may use any other known mechanical means whereby a backward and
forward motion may be imparted to the cycle seat
And in order that this invention may be fully understood I now proceed more
particularly to describe the mode by which I prefer to accomplish its object, and
for that purpose shall refer to the several figures on the annexed drawings
Figure 11s a side view of a bracket or carrier constructed according to this
invention Figure 2 is an end view of the same Figure 3 18 an end view of a
clamp bolt
Figure 4 18 a side view of a seat clamp with rolleis Figure 5 is
a top view of the same. Figure 6 18 an axle for the clamp Figure 7 is a roller
for the clamp
Referring to Figures 1 and 2, A are the end plates in which the tubes B ar
fixed in any suitable manner such as blazing, screwing, or expanding D is the
clamp bolt with plate E and nut F by which the seat post C is fixed to the bottom
row of tubes B
With reference to Figures 4 and 5, G are the side plates and I are the axles on
which the rollers M rotate Lare the nuts which hold the side plates G in position
on the axles I H are the clamp plates and K are the nuts by which the saddle
is attached to the clamp
In operation the clamp (Figures 4 and 5) is moved, by the pressure of the
rider, on a backward and forward direction on the top row of tubes B (Figure 1),
the tubes B passing between the rollers M.
Having now described and particularly ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
-
An attachment for the seats of bicycles, tricycles, and the like constructed so that
a sliding or rolling motion may be imparted to the seat instead of being fixed as
hitherto
