Complete Specification Left, 15th Dec., 1896-Accepted, 23rd Jan., 1897
I WILLIAM FOSTER CHAPMAN of 193 Dewsbury Road, Leeds in the County
of York, Gas Meter Inspector, do hereby declare the nature of this invention to
be as follows:-
My invention refers in the first place to a stand or bracket for carrying a music
desk from a piano for the use of violinists, and also in a new form or arrangement
of desk or support for music books, sheets and the like which is attached to said
stand. The music desk however is generally applicable as a music desk, for
example it may be attached to the piano in place of the present desk for the use
of pianists.
My improved stand or bracket consists of a short E or U shaped clamp which
is placed over the top frame piece of the piano panel and to which it is secured by
a clamping screw or screws passing preferably through the back or inside leg of
the clamp. The front leg of the clamp is provided with a pair of horizontal lugs,
the one above the other and between which fits the upper end of a slightly S bent
arm hereinafter termed the bracket arm. The connection is made secure by
means of a vertical pin which allows the bracket arm however to be moved to one
side or the other. The outer end of the bracket arm is fitted with a piece the
vertical portion having a hole through it in which fits capable of being moved up
and down a vertical rod hereinafter termed the bracket rod. This rod is secured
at any desired height by means of a clamping screw.
The upper end of the bracket rod carries depending therefrom in a suitably
inclined position, the mid bar or rod of the desk frame. The desk consists of top
and bottom horizontal cross pieces or bars, the latter provided with a ledge on
which to rest the music book or sheets. These cross bars are secured to the mid
bars by means of thumb or set screws, several holes or a slot being provided, so
that the top (or both bars) may be secured at any desired height (or distance
apart), to suit different sized sheets of music. The corresponding ends of the top
and bottom cross bars are connected on each side with two bars hinged together
and to the outer ends of the top and bottom.
These four bars are of the same length, and stand vertical or nearly vertical
when the top bar is adjusted at its greater distance from the lower bar, but are all
bent inwards towards each other in any other position.
This music desk is as above stated generally applicable and has the advantage
of avoiding lateral extension when folded down as in the case with ordinary
arrangements of desk frames.
Dated this 20th day of March 1896.

page_text: Improvements in Music Stands and Desks.
I WILLIAM FOSTER CHAPMAN of 193 Dewsbury Road Leeds in the County
of York Gas Meter Inspector 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 :-
My invention refers in the first place, to a stand or bracket for carrying a music
desk from a piano for the use of violinists; and also in a new form or arrangement
of desk or support for music books sheets and the like which is attached to said
stand. The music desk however is generally applicable as a music desk, for
example, it may be attached to the piano in place of the present desks for the use
of pianists.
My improved stand or bracket consists of a short E or U shaped clamp, which
is placed over the top frame piece of the piano panel, and to which it is secured by
a clamping screw or screws, passing preferably through the back or inside leg of
the clamp. The front leg of the clamp is provided with a pair of horizontal lugs,
the one above the other; and between which fits the upper end of a slightly bent
Sshaped arm, hereinafter termed the bracket arm.
The connection is made secure by means of a vertical pin or pins, loose or cast
on the clamp or bracket, which allow the bracket arm however to be moved or
swung to one side or the other. The outer end of the bracket arm is fitted with
a T piece, or formed with a vertical socket, having a hole through it; in which fits
capable of being moved up and down a vertical rod. This rod is secured at any
desired height by means of a clamping screw.
The upper end of the vertical rod carries depending therefrom in a suitably
inclined position the mid bar of the desk frame. The desk consists of top and
bottom horizontal cross pieces or bars; the latter provided with a ledge on which
to rest the music book or sheets. These top and bottom horizontal bars are
secured to the mid vertical bar by means of thumb or set screws, several
holes or a slot or slots being provided, so that the top (or both bars) may be
secured at any desired height (or distance apart) to suit different sized sheets of
music. The corresponding ends of the top and bottom cross bars are connected
on each side with two bars hinged together and to the outer ends of the top and
bottom bars.
These four bars are preferably of the same length, and stand vertical when the
top bar is adjusted at its greatest distance from the lower bar; but are all bent
inwards towards each other in any other position.
This music desk has the advantage of avoiding lateral extension when folded
down.
And in order that my invention and the manner in which the same is to be
performed may be more readily and clearly understood, I have annexed hereto
the accompanying drawings; in which
Fig. 1 is a side elevation of a stand and desk constructed according to my
invention.
Fig. 2 is a plan of the clamp and bracket.
Fig. 3 is a front elevation of the desk proper, and
Figs. 4 and 5 are sections on lines A B and C D respectively of Fig. 3.
a is the clamp, secured to the top frame piece b of a piano panel by means of
the screw c; the underside of the top and the inner side of the front being
covered with cork, felt, rubber or the like, to prevent injury to the panel frame.
For the same reason a knob of rubber may be provided on the top of the clamp a
on which the hinged portion of the piano top may be rested. d'd are a couple of

page_text: horizontal lugs, cast on the fore leg of the clamp, each provided with a hole (or
pin). e is the swing arm or bracket, which is supported from the lugs d on the
clamp by means of a couple of pins (or holes) on (or in) the horizontal lugs f of
the bracket e.
g is the socket piece, at the outer or free end of the bracket e, carrying the
vertical or bracket rod h, which can be clamped at any desired height by means of
the screw i.
The upper end of the bracket rod screws into the boss j at the upper end of
the mid- or carrier bar k of the desk frame, the hole in the boss ; being inclined
to the bar k, so that the latter is held in a suitably inclined position.
The desk consists of top and bottom horizontal pieces or bars 1 and m, the
latter being provided with a ledge to rest the books or sheets thereon. The cross
bars and m are secured to the carrier bar k by means of screws n, and are kept
in a horizontal position by means of guide pieces o, attached to the cross bars and
fitting in grooves or slits p in the carrier bar k, or in which the carrier bar k fits.
The corresponding ends of the bars 7 and m are connected with pin joints on each
side by means of the two bars 9 and r, most suitably of equal length, which are
hinged together at s. This connection of the top and bottom bars and m allows
them to be folded together in the shortest horizontal space.
t is a stay passing from the bottom of the bar k to the bottom of the bracket
rod h, and thereby giving added stiffness to the desk support.
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. A support for music books, sheets and the like, consisting of a clamp, an arm
connected to the clamp by a vertical pin or hinge joint and provided at its free end
with a socket, a vertical rod fitting capable of being raised and lowered and turned
in said socket, and carrying from its upper end an inclined depending rod, to which
latter the desk proper is secured.
2. A music desk consisting of a mid bar, vertical in the plane of the desk and
provided with holes, top and bottom horizontal bars adjustable in height in said
slot holes and provided with guide pieces fitting the said mid bar or the slot holes
in the same and retaining the said top and bottom bars in a horizontal position,
and side pieces connecting by hinged joints corresponding ends of the top and
bottom horizontal bars, said side pieces being hinged together at their adjoining
ends.
