Improvements in Portable Music Stands, Reading Desks, and the like.
We, JOHN WILLIAM DEANS, of Alma Terrace, Selby, Engineer, and ARTHUR Moss
FOSTER, of Park House, Selby, Flax Merchant, do hereby declare the nature of this
Invention to be as follows:-
The object of our invention is to construct portable music stands or reading desks
so that they can be folded up without taking to pieces any portion thereof, also they
can be easily and readily adjusted to any angle.
Our stand or desk is constructed as follows:-
The bottom part consists of a tripod, the legs of which are pivotted to the wings of
a socket, and below are secured to a second socket, this lower socket has short links or
arms pivotted to its wings and to the legs in order to allow the logs to close, these
links or arms are square on their undersides so that the legs can only close inwardly
and cannot be turned upwards.
The outer tube of the stand slides through both sockets and is secured at the
required height by thumb screw or other means.
Within this tube is a second sliding tube, at the upper end of which is an hinge
or joint connecting the stand to the desk or rest so that the desk or rest can be
adjusted and placed at any angle (by means of the joint and thumb screw,) also to
admit of the top or rest folding over when closed, the whole apparatus folds up into a
small compass within the length of the outer tube.
The book rest is made with its ends and sides pivotted so as to fold up; in the
centre at the bottom of the book rest frame, is a projection against which the
edges of the folding frame abut when opened out, so as to keep it perfectly square
and true.

COMPLETE SPECIFICATION.
Improvements in Portable Music Stands, Reading Desks, and the like.
We JOHN WILLIAM DEANS of Alma Terrace Selby Engineer and ARTHUR MOSS
FOSTER of Park House Selby Flax Merchant both in the County of Yorkshire
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 improvements in what are known as portable music
stands reading desks and the like and the object of our invention is to so con-
struct and arrange such portable music stands reading desks or the like that they
can be readily folded up without separating any portion thereof from the rest (as usual
in such stands as hitherto constructed) also they can be easily and readily adjusted to
any desired angle-or-height.
Our stand or desk is arranged and constructed as follows:-The bottom part
consists of a tripod the legs of which are pivotted to the wings of a moveable socket
and below are secured to a second moveable socket by short links or arms pivotted
to it, in order to allow the legs to close these links or arms are square at their inner
ends so that the legs can only close inwardly and cannot be turned upwards.
The outer tube of the stand slides through both sockets and is secured at the
required height by a set screw or the like suitable means.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a view in elevation of our improved stand opened out and stood up ready
for use.
Fig. 2 is a view of the same closed and folded up into a small compass.
Figs. 3 and 4 shew detail views of the joint for hinging the head to the upright rod
of the stand.
Figs. 5 and 6 shew detail views of the arrangement and mounting of the legs.
a, a is the head or book rest which supports the music and which is collapsible as
shown and is well understood a stop b being provided at the bottom of the middle
bar a against which the lower parts a', a' of the head abut to keep the head square
and rigid when opened (see Figs. 1 and 3).
This head piece is jointed at c to the upright rod d which latter moves up and down
on the tube e and is adjusted therein by the set screw or thumb screw f.
The joint c is shown in detail in Figs. 3 and 4.
A shoulder is formed on the part x (of the joint c) attached to the upper end of
rod d as shown in Fig. 4 upon which fits a corresponding shoulder on the part v
attached to the book rest so that this shoulder relieves the the screw or axis h of most
of the weight from the book rest or head and consequently saves wear and strain upon
the thread of the screw or axis h.
The desk or head part a is also adjustable and can be set and held at any desired
angle by the butterfly nut g screwed on the axis / upon which axis the head can be
folded over into the position shewn in Fig. 2. The desk or head part always being
connected with the body of the stand whether folded or open.
It will be obvious that the joint c may be modified by either dispensing with the
wing nut and baving only a smooth pin at upon which the head turns and rests when
open upon the shoulder x as before explained or the shoulders v', ' respectively may
be dispensed with and the wing nut g on the screw pin or axis h used to adjust and
retain the head part at the desired angle.
Figs. 5 and 6 shew the mounting and construction of the legs.
The three legs i are each hinged or jointed direct to a loose collar or socket m on
the standard or tube e upon which said socket m is adjusted at the desired height by
the set screw n Fig. 5 being a plan of m and legs attached.
At a short distance from the top of the legs the links or arms o are pivotted to the
legs at one end and at the other end are pivotted to the wings or projections p
on the second loose collar or socket r which also slides freely on the tube e and is
prevented from coming off sume by the nut or enlarged end e¹ or by other
suitable means.
These links o are arranged as shewn in Fig. 6 (one on each side of each leg :) and
have their inner ends formed square to abut against the socket r and prevent the legs i
from opening too far also as shewn at Figs. 1 and 6 these inner ends lock the socket r
when the links o are at right angles with the tube or standard e thus forming a stop
when the legs are fully opened and prevent the socket r passing the centre.
The connecting of the head part to the body of the stand by pivotting as herein
described and illustrated and with a set screw or thumb-screw to adjust and retain the

page_text: head at the required angle is of considerable importance and has the advantage that
the parts being thereby all permanently connected together and unseparated when the
stand is folded thus prevents the loss or mislaying of any part of the stand which has
been liable to happen with these stands as usually herotofore constructed.
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. In a portable music or the like stand connecting the head or book rest to the
body of the stand by a joint c consisting of parts and provided with shoulders v
and respectively and turning on the axis h having a thread formed on one end
thereof upon which a wing nut g adjusts and retains the parts at the desired angle
substantially in the manner and for the purposes hereinbefore described and repre-
sented in the drawings hereunto annexed.
2. We claim the shoulders ' and v¹ on the parts x and u respectively in combina-
tion with the pin or axis h upon which the said parts turn and form a hinge
substantially as and for the purposes set forth.
3. We claim the stop 6' cast or formed on the bar a² and which enables the head or
desk to be opened and maintained in a rectangular position substantially as and for the
purpose set forth.
4. In portable music stands having the legs jointed direct to a sliding socket we
claim the giving rigidity to such legs when opened by means of the links or arms o
jointed to a second sliding socket the inner ends of which links are formed square
so as to form a stop at the point when the legs are fully opened substantially as herein-
before described and represented in the drawings hereunto annexed.
