Improvements in Cycles.
I, ARTHUR JAMES LEWIS, of Moray Lodge, Campden Hill, London, Gentleman, do
hereby declare the nature of this invention to be as follows:-
My invention consists in a contrivance for the prompt and easy adjustment of
cycle saddles in any required position either backwards or forwards, or at any
desired angle, without the use of the present ordinary screw bolt, nut and
wrench or spanner, which are troublesome and inconvenient. This is effected
by means of a saddle holder or carrier constructed as hereinafter explained,
which is made to slide backwards or forwards by means of a travelling block or blocks
running upon parallel rods or guides forming part of or attached to a plate with cogged
edges projecting on either side, or provided with holes on either side to receive the
bolt or clamp hereinafter referred to, such plate being itself attached to the movable
tube fitting into the frame of the machine in the way hereinafter described.
To this travelling block or blocks any seat may be affixed in any usual or convenient
manner and the invention is therefore adaptable to existing saddles.
When the seat has been moved backwards or forwards into the desired position it
can be therein fixed by means of a sliding clamp, bolt, lever or spring-hinged bolt
engaging with the cogged projections or sunk holes of the plate as aforesaid. To
provide that the saddle may be tilted to any required angle I attach the before
mentioned plate at its centre to the movable tube which supports the seat, and
which runs into the frame of the cycle, by means of a pivotted joint having a
rack and pinion movement fitting into the top of the said movable tube in a jaw
therein properly adapted for the purpose and with suitable means for keeping the
joint firmly fixed at the required angle.
The requisite fitting of the joint and rack and pinion movement may be
effected by various methods, but I refer to the following as being a convenient
and simple one; a metal collar is provided on the tube at the jaw through
which the rack runs, the collar having suitable openings to allow free play to the
rack bar while the saddle is being tilted, and which, on being turned, engages in
the teeth of the rack bar and secures the same in a fixed position.
Dated the 28th day of November 1896.

statement :--
My invention consists in a contrivance for the prompt and easy adjustment of
cycle saddles in any required position either backwards or forwards or at any desired
angle without the use of the present ordinary screw bolt nut and wrench or spanner
which are troublesome and inconvenient.
This is effected by means of a saddle holder or carrier constructed as hereinafter
explained, which is made to slide backwards or forwards by means of a travelling block
blocks or slide running upon parallel rods or guides forming part of or attached to a
plate or frame with cogged edges projecting on either side or provided with holes on
either side to receive the bolts or clamps hereinafter referred to such plate or frame
being itself attached to the movable tube or pin fitting unto the frame of the machine
in the way hereinafter described.
To this travelling block or blocks or slide any seat may be affixed in any usual or
convenient manner and the invention is therefore adaptable to existing saddles.
When the seat has been moved backwards or forwards into the desired position it
can be therein fixed by means of a sliding clamp bolt lever or spring-hinged bolt
engaging with the cogged projections or sunk holes of the plate as aforesaid.
To provide that the saddle may be tilted to any required angle I attach the before
mentioned plate or frame at its centre to the inovable tube or pin which supports the
seat and which runs into the frame of the cycle by means of a pivoted joint having a
rack and pinion movement fitting into the top of the said movable tube in a jaw
therein properly adapted for the purpose and with suitable means for keeping the
joint firmly fixed at the required angle.
The requisite fixing of the joints and rack and pinion movements may be effected
by various methods but I refer to the following as being a convenient and simple one.
A metal collar is provided on the tube at the jaw through which the rack runs the
collar having suitable openings to allow free play to the rack har while the saddle is
being tilted and which on being turned engages in the teeth of the rack bar and
secures the same in a fixed position.
To make my invention more readily understood I refer to the accompanying
drawings in which Fig. 1 is a side elevation of the anddle holder or carrier, constructed
according to my invention in which I shew the plate or frame with notches cut into
the upper edges thereof.
Fig. 2 is an end view thereof.
Fig. 3 is a side view of part of the arrangement for providing the tilting
movement.
Fig. 4 is a view in section showing the adjustable elips forming part of the block
or slide for aflixing the seat and an end view thereof.
Fig. is a cross section showing the method of securing the block or slide for
effecting the horizontal adjustment.
Fig. 6 is a section on line A¹ B¹ of Fig. 1.
Fig. 7 is a view of the means for locking the tilting adjustment.
Fig. 8 is a side view of a modified form of the invention with one locking bolt or
bar only.
Fig. 9 is a plan view of the plate or frame.
A is the tube pin which runs into the frame of the cycle.
B is the head of pin A.
C is the movable collar with small knobs C for operating it.
D is the rack passing through head B and held by the operation of collar C.
E is the joint of plate or frame F
F is the plate or frame carrying the toothed section e and provided with stops e¹ to
limit its movement.
Gis the travelling block or slide for effecting horizontal adjustment.

H, are the lockingholts or bars having slots A to allow slide to be moved and locking 5
same by means of slots f in the sides or edges of plate or frame F the locking bolt

page_text: or bar may be kept in position if necessary by a spiral or any other usual form of
spring N so as to prevent their becoming disengaged.
I are two guides which serve to hold the clips J on the slide G.
g is a screw to prevent clips J from being drawn off the guides I.
11 are suitable holes engaging with the guides I.
Jare radial depressions or channels formed in clips J to receive the springs of
the saddle.
K are the springs of the saddle shown broken off and with seat omitted.
L is the clamp adjusted by the thunb screw nut M to keep the saddle springs
securely fastened.
It is not necessary to duplicate the locking bolt or bar arrangement as shewn
in Figs. 1, 2 and 5 and if desired one locking bolt or bar only may be used as
shown in Fig. 8.
Having now more 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
1. The contrivance for providing horizontal and tilting movement of cycle
saddles substantially as herein described and shewn.
2. The contrivance for tilting and keeping in a fixed position a cycle saddle
substantially as described and shown at C C DE and e and el in the drawings.
3. The contrivance for effecting in cycle saddles horizontal movement substan-
tially as described and shown at F G H h in the drawings.
4. The combination of the device for holding a cycle seat as described and
shewn at I, g, I, J, L and M with the travelling block or slide hereinbefore
described.
