PROVISIONAL SPECIFICATION.
An Improved Hand Guide Apparatus for Attachment to Planos and
other Musical Instruments.
I, ALEXANDER DIELMANN, of 277, Oxford Road, in the City of Manchester,
Professor of Music, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a hand guide apparatus for attachment above the
key-board of a piano or other musical instrument for the purpose of forming a
guide and support for the hands during playing.
In carrying my invention into effect I employ a metallic rod, preferably of a
circular section, extending the whole length of the key-board, and supported at
each end by clamps secured to the framing of the instrument.
I form the clamps preferably of a T shape, the stems having a sorew thread
cut upon them for the reception of the wing nuts by which the sliding pieces and
the heads of the clamp are drawn towards each other and securely clamped to the
framing. A slot is also formed along each stem to receive the nose or point of a
small stud or screw which prevents any rotary movement of the sliding piece.
The upper side of each clamp head is slotted or undercut along its edges to
receive the base of the vertical rods or pillars to which are secured the clip
brackets carrying or supporting the ends of the guide rod. The vertical rods can
be adjusted in position to place the guide rod at the desired horizontal distance
from the key-board by sliding them along the clamp heads, and they are secured
at the required positions by means of a thumb and finger nut on the lower part of
the rods or pillars, or by a screw or stud passing through the base or foot of each
rod. Vertical adjustment of the guide rod is effected by causing the clip brackets
to slide either up or down the rods or pillars. The brackets are clipped to the rods
by a small screw or stud, or by other suitable means.
The horizontal guide rod when thus adjusted to the required position affords a
convenient support and guide for the hands of the player, and at the same time
permitting of perfect freedom of movement along the key-board.

An Improved Hand Guide Apparatus for Attachment to Pianos and
other Musical Instruments.
I, Alexander Dielmann, of 277, Oxford Road, in the City of Manchester,
Professor of Music, 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 relates to a hand guide apparatus for attachnient above the key

page_text: board of a piano or other musical instrument for the purpose of forming a guide
and support for the hands during playing.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to,-
Figure 1 is a front elevation, and Figure 2 a side or end elevation representing
my hand guide apparatus secured to the front of the key board of a pianoforte.
Figure 3 is a side elevation, and Figure 4 a front elevation representing to a
larger scale the adjustable clamps for supporting the guide rod.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect¹ l'employ a metallic rod or tube such as A
extending the whole length of the key board, and supported at each end preferably
by clamps B secured to the framing of the instrument.
I form the clamps B preferably of a T shape, as shown at Figure 3, the stom B'
of each clamp having a screw thread cut upon it for the reception of the wing
nut C by which the sliding piece B2 and the head B³ of the clamp are drawn
towards each other, and securely clamped to the framing. A slot or slots formed
along each stem as illustrated receives the nose or point of a small stud or screw
or the sliding keys b which prevent any rotary movement of the sliding piece B³
during adjustment.
The upper side of each clamp head B³ is slotted or undercut to form the dove-
tailed recess B for the reception of the wedge shaped base of the vertical rod or
pillar D to which is secured the bracket E carrying or supporting one end of the
'guide rod A.
The vertical rods D can be adjusted in position to place the guide rod A
at the desired horizontal distance from the key board by sliding them along
the clamp heads B³, and they are each clamped or secured at the required
position preferably by means of a thumb and finger nut such as F on the
lower end of each rud: Vertical adjustment of the guide rod A is effected by
causing the brackets E to slide either up or down the rods or pillars D. The
brackets E are secured to the rods by a small screw or stud such as e, or by other
suitable means.
•
The guide rod A when thus adjusted to the required position affords a convenient
support and guide for the hands of the player, at the same time permitting of
perfect freedom of movement along the key board.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.―
1. The improved means for supporting and guiding the hands whilst playing a
pianoforte or other musical instrument, substantially as described.
2. The construction of a hand guide apparatus for attachment to pianos and
other musical instruments consisting of a rod or tube such as A supported by
adjustable clamps as B, substantially as hereinbefore described and, as illustrated
in the accompanying drawings.
