IMPROVEMENTS IN SUSPENSION SEATS FOR BICYCLES AND OTHER VEHICLES
Year: 1884

page_text: I WILLIAM PHILLIPS THOMPSON of the Agency for Foreign Patent Solicitors,
6 Lord Street Liverpool in the County of Lancaster, Patent Agent, do hereby
declare the nature of the said invention for "IMPROVEMENTS IN SUSPENSION
SEATS FOR BICYCLES AND OTHER VEHICLES " to be as follows:-
This invention relates to improvements in suspension seats for bicycles and other
vehicles, the object being to provide improved means for supporting a seat in a
suspended position over its frame or base and for taking up the stretch of the
material so that it may not be forced by the weight of the rider upon any rigid
portion of the frame beneath it.
The seat-frame is of the usual corrugated sheet metal having a pommel-shaped
forward end, and having its rear end or border curved downward. It is secured to
the vehicle by the usual yoke.
Ordinarily the leather seat is secured by rivets to the ends of the frame after
having been stretched as much as possible, but continued weight upon the seat
gradually draws it down against the frame beneath when the seat becomes
uncomfortable for the rider.
This invention provides means for keeping the seat leather under proper tension,
and for regulating the latter with great facility according to the wish of the rider.
The rear end of the seat-frame is provided with a circular or curved yoke of flat
bar shape, or having a turned-up outer border like angle-iron, which is hinged to
the frame by staples or other similar means and has a series of screws adapted to
turn in the yoke and having their ends bearing against the frame whereby the yoke
is given a swinging movement to and from the latter.
.
The seat-leather is riveted by rivets or otherwise suitably and rigidly attached to
the small or pommel-end of frame and as usual is of sufficient size to cover and
hang over the borders of the frame. The rear-wide end of the seat is carried over
the aforesaid curved end of the frame at the rear, and is firmly attached to the
border of the yoke by rivets or other suitable means.
The seat-leather is then drawn to the proper tension over the upper surface of the
frame by forcing screws against the latter under the yoke and causing the latter to
swing from the frame, thereby suspending the seat leather by its two ends over the
part of the frame there between, and by operating the screws the leather may be
strained to suit the convenience of the rider.
Parcels can be secured to the frame by straps passing through staples:

6 Lord Street, Liverpool, in the county of Lancaster, Patent Agent, do hereby
declare the nature of the said invention for "IMPROVEMENTS IN SUSPENSION
SEATS FOR BICYCLES AND OTHER VEHICLES" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in suspension seats for bicycles and other
vehicles, the object being to provide improved means for supporting a seat in a
suspended position over its frame or base, and for taking up the stretch of the
material so that it may not be forced by the weight of the rider upon any rigid
portion of the frame beneath it.
In the drawing forming part of this specification, Fig. 1 is a plan view of the
bottom of a scat, embodying the improvements. Fig. 2 is a side elevation partly
in section.
In the drawing, A is the usual .corrugated sheet metal seat frame, having a
pommel shaped forward end, and having its rear end or border curved downward.
The usual yoke by which the seat is secured to the vehicle, is indicated by e.
Ordinarily the leather seat b is secured by rivets to the ends of the frame A after
having been stretched as much as possible, but continued weight upon the sent
gradually draws it down against the frame beneath, when the seat becomes
uncomfortable for the rider.
The improvements provide means for keeping the seat leather b under proper
tension, and for regulating the latter with great facility, according to the wish of
the rider.
The rear end of the seat frame A, is provided with a circular or curved yoke c
of flat bar shape, or having a turned-up outer border like angle-iron, which is
hinged to the frame by the staples d d or other similar means, and has a series of
screws v, adapted to turn in the yoke, and having their ends bearing against the
frame A, whereby the yoke is given a swinging movement to and from the latter.
The seat leather bis riveted by rivets 22 or otherwise suitably and rigidly
attached to the small or pommel end of frame A, and as usual is of sufficient size
to cover and hang over the borders of the frame. The rear wide end of seat b
is carried over the aforesaid curved end of frame A at the rear, and is firmly
attached to the border of the yoke c by the rivets z or other suitable means.
The seat leather bis then drawn to the proper tension over the upper surface of
the frame A by forcing the screws against the latter under the yoke and causing
the latter to swing from the frame, thereby suspending the seat leather by its two
ends over the part of the frame there between, and by operating screws
leather may be strained to suit the convenience of the rider,
the
The staples are those usually secured to frame A whereby parcels are secured
to the latter by straps passing through them.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1st. The combination with the seat frame A and with the elastic seat material b,
secured rigidly to one end of the frame, of the yoke c, having the free end of said
material secured thereto, and capable, by means substantially as described, of a
swinging movement towards and from the frame, substantially as set forth,
1

page_text: 2nd. In combination, the frame A, the yoke c, hinged to said frame, and provided
with screws, passing through it and bearing against the latter, and the seat
material secured by one end to the frame, and by the other to said yoke,
substantially as set forth.
