ascertained in and by the following statement and drawings
The object of my invention is that my improved attachments can be adjusted to
any pianoforte, and the centre adjustable fulcrum can be adjusted to suit the touch
of any pianoforte action instantly.
DESCRIPTION OF DRAWINGS.
Fig 1, is an elevation in section of pianoforte frame or case, with my improved
organ pedal attachments applied thereto.
Fig 2, shews plan of underside, of adjustable sliding levers, balance rod, frame-
work and basis for framework.
Figs. 3 and 4 shew different forms in which the sliding levers may be made.
Figs 5 and 6 shew different forms of adjustable sliding levers detached.
Figs 7 and 8, shew modifications of pedals detached.
A is the frame of pianoforte, B shews key, C is the stem connecting the keys
with adjustable pin D, and bushed mahogany guide D1, D2 is the loop at the bottom
of the adjustable pin D, by which the tone of any one key can be modified, E is
the adjustable sliding lever secured by clamps or fasteners such as F and F¹, so as
to be easily adjusted to any pianoforte, S is the adjustable balance rod, G is the
adjustable guide, H is the sticker, adjustable by means of an eye bolt or
fastener J, K is the felt or other nut, L is the felted wood button, M is a cap of
wood, or other material, N is a mahogany or other guide, which keeps the short
sticker O steady, and noiseless when actuated, the short sticker O is connected to
a lever P, by means of an eye, which passes through the bushed hole in the lever P,
and is afterwards closed, R is the grooved fulcrum, in which the lever P is fixed,
U is the screwed pin with eye, the thread pin being screwed into the underside of
pedal T, the eye passes on the end of the rounded part of the lever P, U is the oval
screwed pin for adjusting and keeping.firm the pedals, W is the pianoforte elevator,

page_text: X is the basis for framework, which is adjustable to any pianoforte, Y is the
adjustable fulcrum for sliding lever E, this fulcrum and the balance rod S, allows
of adjustment not only to any pianoforte, but they can also be adjusted to the
following modifications of tone namely:-m f, f, ff, and can also be modified by
the performer; it should be distinctly understood, that the full compass of the
'pedals, can be modified in tone, by the aforesaid adjustable fulcrum and balance
rod. The mechanism shewn at the end of pedal see Fig. 7, allows of modification
of tone, by moving the pedal frame as well as by the adjustable fulcrum Y.
The mechanism shewn at end of pedal see Fig 8 is suitable only for lever
shewn at Fig 3. and is modified in tone throughout by the adjustable fulcrum Y,
and balance rod S.
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
1 The sliding lever E adjustable (or non-adjustable) to suit any pianoforte in any
position, and any lever attachment.
2 The combination of the sliding adjustable (or non adjustable) levers, and
balance rod.
3 The adjustable fulcrum Y, for any form of lever or levers, in any position,
whereby the tone of the full, or part compass of the pédals, can be modified either
for actuating the keys in front or behind.
4 The adjustable oval screw pin V for adjusting and keeping the action and
pedals secure and firm, and also for preventing sticking.
