I CHARLES ALLAN JONES of Hatherley Court Gloucester Solicitor do hereby
declare the nature of my said invention for IMPROVEMENTS IN FOLDING TABLES
MUSIC STANDS OR DESKS OR STANDS OF A SIMILAR NATURE to be as follows:-
The application of a double parallel action (similar to that shown in the
accompanying drawings or end elevations) to tables music stands or desks or
stands of a similar nature whereby the apparatus can be opened out adjusted or
collapsed at one motion.
To ensure the two parallel actions composed of the bars A A, B B, C C, and D
opening or closing simultaneously and equally on either side of the central bar D
I make a slot in the said bar D through which slot the pin connecting the upper
ends of the two bars E E passes and also pivot these bars E E to each of the
parallel actions at the points F F. The top of the apparatus being in two
portions respectively resting on or attached to the bars A A I ensure their remaining
level when opened out as a table as in Figure 1 by limiting the length of the slide
for the pin in the before mentioned slot, and by having a thumb screw or other
such tightening or locking contrivance on this pin, the slide of the pin may be
arrested or locked at any intermediate point in the slot as in Figure 2 which shows
the apparatus in a suitable position for a desk or music stand.
This apparatus may be made of any desired length and in long lengths is suitable
for school desks. I do not confine myself to the precise form and details of the
apparatus shown in the drawings.

Stands of a similar Nature.
I CHARLES ALLAN JONES of Hatherley Court Gloucester Solicitor do hereby
declare the nature of my invention for IMPROVEMENTS IN FOLDING TABLES MUSIC
STANDS OR DESKS OR STANDS OF A SIMILAR NATURE and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The nature of my said Invention is the application of a double parallel motion
to folding tables music stands or desks or stands of a similar nature whereby the
same can be opened out adjusted or collapsed with great ease and rapidity at one
motion.
In the accompanying drawings Figure 2 represents a perspective view of the
apparatus opened out and ready for use as a table.
The bars A A, B B, C C, and D which form the double parallel motion are
connected as shown by rivets or other suitable pivot joints.
By pressing the top at the points G G downwards the apparatus is easily and
rapidly closed in which position it is shown. Figure 3.
To ensure the two parallel motions composed of the bars A A, B B, C C, and D
opening or closing simultaneously and equally on either side of the central bar D
I make a slot as shown in the said bar D and through a block H loosely fitted in
this slot pass the pin connecting the lower ends of the bars EE I also connect
these bars E E to each of the parallel motions at the pivot joints F F so that in
opening or closing the apparatus the block H slides up or down the slot. The top
of the table is in two portions resting on and attached to the bars A A and to
ensure their remaining level when opened out as in Figure 2 the length of the slide
for the block H in the slot is limited and the top may be made in unequal portions
as shown in the drawings so that the longer portion on the right hand side rests
on the bars A A. on the left hand side when open.
By having a thumbscrew on the pin which passes through the block H the slide
of the block may be arrested or locked at any intermediate point in the slot as in
Figure 2 of the drawings accompanying my provisional Specification which shows
the apparatus in a suitable position for a desk or music stand.
The apparatus may be made in long lengths suitable for school desks.
Figure 1 is a plan of the table with the top partially removed to show a
convenient mode of arranging the bars A A, B B, D and E E, the bars C C are
similarly arranged, J is a convenient form of bolt which slides in two suitable
blocks K K attached to the underside of the longer or right hand portion of the
top and before the table can be closed this bolt must be withdrawn from under
the left hand portion of the top.
Although I have made use of the term "parallel" motion and have shown such
motions geometrically parallel the bars C C may be made longer than the bars A A
so as to make the bars B B taper outwards at the bottom and afford a wider base
for the apparatus to stand on.
I do not confine myself to the precise form and details shown in the drawings.

page_text: 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
い
1. The arrangement and combination of parts constituting the folding table
music stand or desk substantially as hereinbefore described with reference to the
drawings.
2. In folding tables music stands or desks or stands of a similar nature the
combination of the bars A. A, B B, C C, D and E E and the sliding block H and
the slot in D operating substantially as and for the purposes hereinbefore described
and illustrated.
