AN IMPROVEMENT CONNECTED WITH SEATS FOR SITTING ON to be as follows:
Year: 1884

page_text: I ALFRED JAMES BALE of North Dulwich in the county of Surrey Engineer do
hereby declare the nature of my said invention for "AN IMPROVEMENT CONNECTED
WITH SEATS FOR SITTING ON to be as follows:-
"
The object of the first part of this invention is to so construct or arrange a seat:
that it may adjust itself to the desired angle according to the wish of the sitter
when the weight of the body by a lean back or a lean forward action be convenient
for obtaining comfort.
The seat may if desired be provided with appliances for fixing it temporarilly at
the desired angle.
The object of the second part of my invention is to construct or arrange a seat
proper in two portions and to balance each portion on the same or on independent
axles or supports that either portion may move and adjust itself to the varying
angles produced by the motion of the legs of the rider particularly when riding a
bicycle or a tricycle.
.
According to the first part of my invention I balance or affix a seat transversely
across its centre or near thereto on an axle, stud pins or bearings so that it is free
to move or be moved and be set if desired by any appliance at any angle conducive
to the comfort of the sitter.
According to the second part of my invention I divide or form two half seats on -
the same or on independent bearings, axles or supports arranged transversely at or
about the centre and in such a manner that each division or half seat can have a
motion up and down front and rear independently of the neighbouring division or
half seat. This latter arrangement is particularly adapted to bicycles, tricycles
and like vehicles on or by which the legs of the rider are lifted and depressed"
alternately each half seat then following the angle governed, or controlled by the
motion of the legs during such action.

"AN IMPROVEMENT CONNECTED
hereby declare the nature of my said invention for
WITH SEATS FOR SITTING ON" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :—
The object of the first part of this invention is to so construct or arrange a seat
that it may adjust itself to the desired angle according to the wish of the sitter
when the weight of the body by a lean back or a lean forward action be convenient
for obtaining comfort.
The seat may if desired be provided with appliances for fixing it temporarilly at
the desired angle or for returning it to its normal position.
The object of the second part of my invention is to construct or arrange a seat
proper in two portions and to balance each portion on the same or on independent
axles or supports that either portion may move and adjust itself to the varying
angles produced by the motion of the legs of the rider particularly when riding a
bicycle or tricycle..
According to the first part of my invention which I show at Figures 1 and 2 of
the annexed drawings I balance or affix a seat A transversely across its centre B or
near thereto on an axle, stud pins or bearings C so that it is free to move or be
moved and be set if desired by any appliance E Figure 1 at any angle conducive to
the comfort of the sitter.
According to the second part of my invention which I show at Figures 3, 4, 5
and 6 1 divide or form two half seats A, A¹ on the same or on independent bearings,
axles, or supports B, B, arranged transversely at or about the centre and in such a
manner that each division or half seat A or A¹ can have a motion up and down
front and rear independently of the neighbouring division or half seat. This latter
arrangement is particularly adapted for bicycles, Figures 3 and 4, or to Tricycles
and like vehicles as at Figureš and 6 the legs of the rider being lifted and
depressed alternately so that each half seat follows the angle governed or con-
trolled by the legs during such action.
"
The representations in the figures are sufficient for the purpose of illustration
and will enable the invention to be fully understood.
Having now 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
First Hinging or pivoting seats of chairs and other like articles of furniture at
or about their central line transversely to enable the angle of said seat to be
altered as described and as shown at Figures 1 and 2 in the annexed
drawings.
Secondly The construction and application of half seats to tricycles, bicycles and
the like as and for the purpose described with reference to Figures 3, 4, 5
and 6 of the annexed drawings.
