PROVISIONAL SPECIFICATION.
Improvements in Adjustable Seats.
We, JAMES MCHARDY of Fairfax House Chiswick Scientific Expert and
WALKER GEORGE DE FORGES GARLAND of East Molesey Manufacturer do
hereby declare the nature of this invention to be as follows:-
This invention which relates to improvements in adjustable seats, is carried into
practice somewhat as follows.
A false seat and a supplimentary shelf or base (or their equivalents) are pro-
vided with such holes and apertures as to be capable of receiving the rigid legs
or supports, and also such rods and screws as shall be capable of sliding upwards or
downwards through one, or both of them. The said rods and screws shall be so
joined to the real seat above, as to admit of its being adjusted, not only to various
heights, but also to any desired inclined position, (common hinges, or any hinge-
joint-construction may be employed for this purpose).
The screws hereinbefore described, do not revolve as they are hinged to the
seat, but, passing through the before mentioned false seat or platform, are governed
by nuts above and below, by which the seat proper is raised or lowered, or caused
to take up an inclined position, and there, is rigidly retained by screwing the nuts,
after the manner of jam-nuts.

Improvements in Adjustable Seats.
JAMES M'HARDY of Fairfax House Chiswick Middlesex Scientific Expertn d
WALKER GEORGE DE FORGÉS GARLAND of East Molesey Surrey Manufacturer
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 which relates to improvements in 'adjustable seats is carried out as
follows.
A false seat and a supplimentary shelf or base (or their equivalents) are provided
with holes and apertures capable of receiving rigid legs or supports, and also such
rods and screws as shall be capable of sliding upwards and downwards through one
or both.
A duplex base is thus formed as the legs or supports are attached so as to fix the
so-called false seat, at a given height above the lower platform or shelf and parallel
to it. One or more square (or suitably shaped holes) holes in the double platform
or base is or are provided, capable of receiving a guide-piece. The seat itself is
hinged upon one (or if a long seat, two guide pieces) guide piece, and several
adjusting bolts. The said guide piece passes through both platforms of the
duplicate-base and serves to keep the parts in line. The adjusting bolts pass
through the false seat or upper platform of the base only. Nuts, working on the
said bolts above and below the top of the base, it follows that these enable us to
raise or lower the seat or to give it a desired slope in the direction of the hinge-
joints of the said guide and bolts, as also to cramp the seat so that it may not
creak or work loose.

page_text: We construct a single seat with only one guide-piece and three hinged bolts, but
for organ-seats, or seats for several persons we may use any number of guides or
bolts.

iiii-The nuts above and below the upper platform or false seat.
Fig. II. in which the lettering and figures are similar to Fig. I., shows the
adjustment both as to bevel and height.
Fig. III. A plan of the lower side of a a in Fig. I. and the reference is also

Fig. IV. A plan for an oblong seat with several guide-pieces lettered as
above.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;
1. An adjustable seat capable of regulation as to bevel as well as height, as
herein described.
2. The combination of several adjusting bolts hinged to a seat in such a manner
as to admit of motion in the transverse direction in combination with a telescoping
guide similarly hinged.
