Improvements in Portable Collapsible, Folding, and Adjustable Music
Stands, Reading Desks, and the like, parts of same being
applicable to other analogous purposes.
We JOHN WILLIAM DEANS of Alma Terrace Selby and ARTHUR MOSS
FOSTER of Park House Selby both in the County of York trading as Deans & Co.
Music Smiths and Musical Instrument Makers do hereby declare the nature of this
invention to be as follows:-
:-
Our present invention has for its object to perfect or improve the means of
adjusting the height of music stands reading desks or the like or other analogous
supports or stands such as dress stands hat and bonnet stands and similar shop
fittings especially for shop windows and display purposes and secondly our present
invention relates to improved method and means of adjusting the angle and then
fixing in position the desk or head part i.e. the part which carries the music or other
book paper or article to be displayed or supported.
For this purpose we proceed as follows:-
The feet or legs or under part of the stand may be of our well known patented
tripod form and construction (according to our Patent No. 11257 of 1888) or of any
other suitable form or construction.
A. central vertical tube (adjustable as to its height in the said under part of the
stand or not) has telescopically combined therewith a rod or tube upon which the
head or desk is hinged jointed or supported, or the said vertical tube and telescopic
arrangement may be dispensed with and the rod or tube carrying the head part
may slide up and down and be fixed at any desired height in the tripod or under
part direct.
It is the means of rigidly and effectually clamping and fixing these upright rods
tubes or parts at any desired height and readily releasing same again that form the
first part of our present invention.
For this purpose we form a lug or projection having an opening therein at right
angles (or thereabouts) to the direction of the extension movement of the part or
parts to be adjusted and through this aperture we insert a pin or projection on a
loose fitting collar which latter is fitted loosely on the said rod or tube and more or
less corresponding in shape to the shape of the part it surrounds.
The end of this pin or projection on said collar has a wing nut screwed into or
onto it or other equivalent device to firmly draw the said collar across the path of
travel of the adjustable rod etcetera and so tightly grip said rod etcetera and
jam it against the internal side of the tube aperture or opening through or within
which it works.
One or more of these gripping collars may be arranged and mounted at any
point or points on an adjustable stand or supporting device of the character herein-
before set forth.
The second part of our invention relates to the adjustment of the desk head or
supporting part at the top of the stand and we may effect this adjustment and
locking in either of the three following ways, as follows:-
In each case we form or mount a disc or wheel-shaped or similar device swelling
or enlargement (advantageously circular on its periphery) rigidly and permanently
on the outer end of the aforesaid telescopic or other adjustable sliding supporting
rod or tube and having a pin or axis or otherwise hinged or jointed (permanently
or not) to the head or desk or top part so that the latter can be folded over as
desired.
This disc or wheel-shaped device has the desk or head part pivotted or hinged

page_text: thereto by means of two lugs or bearings on the head part and a pin or axis
passing through same and through the said disc or wheel-shaped device or by
means of only one lug or bearing or equivalent.
Firstly. We make the locking in position at the desired angle automatic by
making a part or projection on the spreading folding desk engage and enter into
one of several slots recesses or serrations on the said disc or wheel shaped
device or enlargement.
Upon placing the desk or head part at the desired angle and then opening out
the folding parts thereof the said part or projection thereon will enter one of the
slots or serrations and thereby automatically lock the head part at the angle
.desired while in the act of unfolding or setting the said head part ready for use.
Upon folding up the book rest or head part the lock is withdrawn or released.
Or in place of the foregoing a spring bolt or catch mounted on the head part
could be arranged to enter any of the said slots or serrations and so lock the two
parts at any desired angle but this arrangement would not be quite automatic.
Secondly. In place of the slots or serrations we dispense with same and adjust
and lock as follows.
A link is pivotted at its one end to the head or desk part and at its other
end has a lengthened slot within which operates a pin or projection cast or fixed
on the said disc or wheel-shaped device and has a tightening device thereon such
as a wing nut or thumb screw or instead of the pin a thumb screw may pass through
said slot in the link direct into the said disc or enlargement and in either case by
tightening up the wing nut or thumb screw the said pivotted and slotted link will
be fixed tight in position and so the angle of the head rest or desk part can be set
and adjusted and fixed in position.
•
Thirdly. Instead of either the serrations or the slotted link we may use simply a
latch pivotted to the head part at one end and at its other having a tooth or
teeth which engage a pin projecting out of the side of the said dise or enlargement
and so fix the head or desk part in position at any desired angle.
A suitable knob or handle is mounted or formed on this latch by which to grasp
and fix or release same.
By our present invention we greatly improve such stands etcetera our object being
to more rigidly and firmly set up and fix the various parts in position so as to give
great strength and rigidity while in use.
All the various parts may be cast or otherwise suitably formed from metal or
other suitable material or materials.

COMPLETE SPECIFICATION.
Improvements in Portable Collapsible, Folding, and Adjustable Music
Stands, Reading Desks, and the like, parts of same being
applicable to other analogous purposes.
We, JOHN WILLIAM DEANS of Alma Terrace, Selby, and ARTHUR Moss 4
FOSTER of Park House, Selby, both in the County of York, trading as Deans & Co.,
Music Smiths and Musical Instrument Makers, 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 :-
Our present invention has for its object to perfect or improve the means of
adjusting the height of music stands reading desks or the like or other analogous
supports or stands such as dress stands hat and bonnet stands and similar shop
fittings especially for shop windows and display purposes and secondly our present

page_text: invention relates to improved means of adjusting the angle and then fixing in
position the desk or head part i.e. the part which carries the music or other book
paper or article to be displayed or supported.
And in order that our present invention may be fully understood and readily
carried into practice we will proceed to describe same with reference to the
drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents in side elevation a music stand having our present improvements
applied thereto.
Fig. 2 is a local front view (on an enlarged scale) of the means of adjusting the
head or music desk at the desired angle.
Fig. 3 is a side elevation of Fig. 2.
Fig. 4 is a local side view (on an enlarged scale) of our improved means of
clamping the vertical adjustable rods etc. at the desired height.
Fig. 5 is a plan of Fig. 4.
Figs. 6 and 7 respectively show side and front elevations (local views) of a
modified means of adjusting the music desk or head of a stand at the desired
angle.
Fig. 8 shows an adjustable seat or music stool the seat of which is capable of
being easily adjusted vertically and secured at the desired height according to our
present invention in a very firm and safe manner.
a a are the legs of the music stand shown at Fig. 1 and of the music stool or
adjustable seat shown at Fig. 8 and we would here remark that such legs form no
part of our present invention as we have already received Letters Patent for such
legs under date 3rd August 1888, No. 11257.
If desired any other suitable legs or under-support may be used.
b is a vertical adjusting tube within which slides a rod c the latter carrying
thereon any suitable head rest desk seat or other device or contrivance according
to the desired purpose to which our present improvements are to be applied and we
would here remark that it is not this telescopic combination which forms the first
part of our present invention but this first part of our invention consists solely of
the means of readily clamping and rigidly fixing these telescopic parts together
and again readily releasing same so as to allow them to slide freely one within or
on the other when desired.
d is a lug or projection on tube b and also a similar lug or projection e is formed
or mounted on the upper part of the tripod or other stand a-each such lug or
projection de having a hole bored or formed therein at right angles (or there-
abouts) to the line of travel of the extension movement of the parts b and c or of
the extension movement of 6 in the tripod or other stand a see Figs. 1 and 8.
is
fis a loose collar lying across the path of travel of the extension rod c and g
a similar loose collar lying across the path of travel of the rod or tube beach such
collar respectively loosely fitting around the tube or rod passing through same and
of a shape internally to more or less correspond with the shape of the rod or
tube etc. which it surrounds.
h is a pin or projection formed or mounted on each of these loose collars fand g
respectively and this pin or part h passes through the aforesaid aperture in the
lug d or e and is screw threaded to receive thereon a suitable tightening device
such as the winged nut i so that by tightening up the latter the collar fis drawn
towards the lug d and thus tightly grips and firmly holds the extension rod c from
moving in bor vice versa-also the winged nut i acts in precisely similar manner
upon the collar g to hold the tube 6 tightly upon the tripod stand until said nut i is
slacked upon the screw pin h.
It will be obvious that other mechanically equivalent devices can be used for
actuating the collars for g for instance in place of the screw pin h being fixed to
the said loose collar for g-said screw pin may be formed separately and have a

page_text: suitable head or device by which to grasp same and this pin is passed through the
lug d or e and enters a lapped hole in the collar (or a cam motion may be thus
imparted from such a pin to the loose collar) so as thus to draw said collar towards
the said lugs or force same away therefrom as desired and thus lock the one
extension part upon and to the other.
In Fig. 8 we have shown this part of our invention applied to a music stool or
adjustable seat x and as the vertical strain in such a case is very heavy we
therefore use a rather stout rod 6x which is fixed to the seat x and passes
through the collar 9 (arranged to act as previously described with reference
to the other figures of the drawings) which operates just above the top of a four
legged stand or support a or any other suitable support. To make the fixing more
secure we cut a series of teeth or otherwise serrate the rod * as shown and a
corresponding surface on the inside of the loose collar 9 and thus when the
collar g forced tightly into one of the indents y in the rod 6x a very firm grip
is obtained and maintained until the collar g is released by slacking away by the
wing nut i or other equivalent means.
The second part of our present invention relates to the adjustment and fixing in
position of the desk part or other adjustable supporting head or device for carrying
sheets of music, books, or other objects or articles and we would here remark that
we may use this second part of our invention in combination and in conjunction
with the first part or entirely independent and separate therefrom and in the same
way the first part may be used either with or without the second part.
Referring now to Figs. 1, 2, and 3-the head adjustment in the case there
illustrated is as follows:-
The upper or outer end of the extension rod c has a disc or wheel-shaped
swelling or enlargement m thereon having a pin or axis n passing through its centre
upon which pin or axis n the two cars or forked ends oo of the desk or head p are
pivotally mounted so that the head part p is permanently connected to c these two
parts being free to turn on the axis or pivot n and thus being capable of folding
over one upon the other and lying snugly together when desired.
To adjust and firmly hold the head p at the desired angle with respect to rod c
we pivot the slotted link to one side of the head p so that r can oscillate on the
pin or axis s in head p, while a clamping device such as the winged nut t on being
screwed up tightly on the screwed pin u (which latter is rigidly fixed to the
part cm) serves to firmly fix the head p in any desired position.
The pin u passes through the slot in the link r and a washer v is provided
(see Fig. 2) against which the link r is forced.
The clamping of the link may be effected in other obviously equivalent ways
for instance by the device t having a screwed pin fixed thereon which latter would
be screwed into the part cm thus giving the same effect to clamp and hold the
head p in position.
The back (or front) of the link may be serrated roughened or the like to
produce a greater grip and binding effect.
Referring to Figs. 6 and 7-in this case the adjustment is obtained by cutting
teeth or indents w in the disc m (which latter is mounted on cas just previously
described and has the head part p pivotally connected also) and dispensing with
the slotted link and in place thereof we cast or mount a locking piece (see Fig. 7)
on the lower pivotted bar px of the head part p so that when this hinged bar p*
(which turns on the axis pl as is well known and understood) is moved down to the
horizontal position that is when the collapsible head p is opened the locking
piece will enter one of the teeth w in the disc m and thus automatically lock
the head p at the desired angle at the moment and by the same action when
opening same.
Or instead of either the slotted link or teeth w and locking piece z we may fix
the head p in position by a hook or latch pivotted to p about the same as link is
pivotted at s and the catch on the other end of said latch would engage a fixed pin
or stud on cm and thus fix the head p in position.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
—
1. In portable collapsible folding and adjustable music stands music stools
reading desks or the like having a telescopic extension action-the combination
therewith of a lug or projection such as d or e on one of the extension parts and
a loosely fitting collar such as for g which encircles the other extension part
sliding therein or thereon and by forcing this collar across the path of travel of
the one part upon the other (of the said telescopic parts) thereby locking same
tightly in any desired position substantially in the manner and for the purposes
hereinbefore set forth and illustrated in Figs. 1 and 8 of the drawings hereunto
annexed.
2. The improved means of locking one telescopic part upon the other substan-
tially as shown at Figs. 4 and 5 of the drawings hereunto annexed viz. a lug or
bearing such as d fixed on one extension part to serve as the resistance or thrust
bearing against which a tightening device such as i operates to force a loose collar
such as facross the path of travel of the other extension piece so as thereby to
lock together these two said extension parts at any desired point and readily
release same again substantially in the manner and for the purposes herein before
described and set forth.
3. The improved means of fixing the head rest or desk part such as p at any
desired angle with respect to the vertical supporting device-consisting of the
combination of a slotted link pivotted to said head or desk part and a pinching
screw or clamp passing through said slot and operating in the under support (to
which latter the said desk part is pivotally connected or hinged-as shown) so as
thereby to clamp and firmly fix the head at any desired angle substantially as and
for the purposes hereinbefore set forth and illustrated at Figs. 1, 2 and 3 of the
drawings hereunto annexed.
4. The modification shown at Figs. 6 and 7 and consisting of the locking piece z
fixed on the folding lower part of a folding music rest or the like in combination
and acting in conjunction with teeth or indents w cut or formed in the disc-shaped
head m of the under support so that when the folding head p is opened the said
locking piece on the bar p* will enter one of the indents w and thereby auto-
matically lock the head p at the desired angle substantially as and for the purposes
herein before described and illustrated at Figs. 6 and 7 of the annexed drawings.
5. The improved general arrangement construction and combination of parts of
portable collapsible folding and adjustable music stands reading desks or the like-
parts of same being separately applicable to other analogous purposes substan-
tially in the manner and for the purposes hereinbefore described and illustrated in
the drawings hereunto annexed.
