Improvements in Velocipedes.
I, PURNELL PURNELL of 5 Montagne Terrace, Friarstile Road, Richmond, in the
County of Surrey, Gentleman, do hereby declare the nature of this invention to be as
follows:-
According to this invention I make the seats of velocipedes especially those known
as safety bicycles adjustable in height in such a way that the rider can when he wishes
to get off let the seat drop and his feet descend to the ground or in mounting can
get onto the seat whilst his feet are still on the ground and then allow the seat to
rise with him.
I mount the seat upon an arm pivotted to the stem carrying the steering handles
the arm is either. a spring arm or else springs are interposed between it and the
seat. The arm has a tendency to rise being forced up by a spring or otherwise and it
carries a bolt which takes into holes in a vertical quadrant fixed to the backbone or
bar connecting the front and hind wheels. The bolt is actuated by a cord or rods
passing along the pivotted arm and up to the handle.
In place of mounting the seat upon a pivotted arm it may be supported on a
telescopic stem, the seat being allowed to drop at pleasure as before described.

what manner the same is to be performed to be particularly described and ascertained
in and by the following statement:—

along the pivoted arm and up to the handle.
In order that my said invention may be more fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1. shows a side elevation of a safety bicycle to which my invention is applied.
The lower position of the seat is shown in dotted lines.
A is an arm pivoted at B to the stem carrying the steering handles. C is the
seat. The arm A is slotted at D to receive the quadrant E, carried by the back bone
of the machine. The arm. A is hollow and has inside it a bolt F as shown in vertical
and horizontal section at: Figures 2 and 3. The bolt F is pressed outwards by the
spiral spring G and takes into one or other of the teeth in the quadrant E.
Figure 4 is an elevation of the left hand half of the steering handle, it carries the
lever H pivoted at H¹, which is connected to, and actuates, the bolt F, by the rod H²,
bell crank lever H³ and connecting rod H. Jis a cord one end of which is fixed
to the arm A and the other to the fusee K as shown in figures 1 and 5. The fusee K
is driven by a coiled spring in the barrel L, so that the cord J has a tendency to be
wound up upon the fusee K drawing up the seat when the bolt F is withdrawn.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it understood that
I do not claim generally a velocipede whose seat has a tendency to rise when allowed
to do so, nor do I claim retaining such seat at any desired height by a bolt under the
control of the rider, but what I claim in connection with such velocipedes is :-
1. Carrying the seat on an arm pivoted to the frame of the machine.
2. Mounting and controlling the seat substantially as described and shown in the
drawings.
