COMPLETE SPECIFICATION.
An Adjustable Music or Book Desk.
EDWARD FREDERICK FIELDER 46 Elswick Road Lewisham in the County
of Kent Decorator 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 :—
I construct of suitable materials a desk which can be adjusted to the position
required in the following manner.
take a piece of wood, metal or other materials suitable for the purpose
according to size required and form it to the shape A. Sheet 1. a small piece to be
cut out as A. 1. for the screw of the centre guide to pass through.
If it is required to project the piece A beyond the mouldings or projections
of pianofortes or other instruments or appliances, I fix two blocks of either
shape B. or B 1. (or various other shapes) as A. 2. to this I fix the hinges, hooks or
other means to hold the desk.
If an hinge as C. is used these blocks need not be used, the portion C. 2. is
screwed to the back of A.
I next make of brass or other suitable materials three guides as D. but the one for
the centre to have a screw as E. to pass through the back to the front as D. 1. and D. 2.
the nut ou the front, these are to be riveted to the piece A. Then make of wood
or other suitable materials a piece to the shape as H. the same length as A. and one
slotted piece as I. according to the depth of desk required and two pieces as K. or
other shapes two or three inches longer or more if required. I then rivet the
piece 1. to the back in the centre of H. and the two pieces K. near the ends with
washers of brass or other materials suitable between, and then pass 1. K. K. through
the three guides D. D. D. and pass the screw E. through the centre one from the
back, through the slotted piece I to the front, then place on the nut.
The bottom part of the desk M. where the music, books &c. rest can be made the
same length as A. or longer, the three uprights I. K. and K. are riveted to M. as
in Figure 1. Sheet 2. I then make two slotted pieces as N., and then on the bottom
of M. I fix a piece a little thicker than N. in the position as M. 3. but M. 2. is a
washer thicker than the back of the screw O., then the two pieces N. are screwed
with a washer to the bottom of M. on the pieces M. 3. and the washer M. 2. The

page_text: screw O. that passes through and regulates the two slotted pieces N. is made the
same as E.
The clevation of desk complete is shown in Figure 1 Sheet 2.
The desk will fold right or left' by means of the guides working on the rivets as
shown in Figure 2 Sheet 2.
When the piece A. is fixed or hung by hooks, hinges or other means on the
blocks B. or B 1. or without the blocks and by hinge C. the whole of the desk can
be raised and lowered by means of the uprights K. K. I. sliding through the three
guides D. D. D. and fixed by the screw E, which grips the slotted piece I. with the
back flanged part of the screw, as shown in Figure 3. Sheet 2.
And when adjusted the angle or pitch of the desk is given by means of the two
slotted pieces N. extending and fixed by the screw O. in the same manner as the
screw E. which grips the slotted pieces together.
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 guides with and without screw, then fitted to a desk described as above,
the desk can be raised or lowered, and when not required can be folded.
2. The two slotted pieces and screw, arranged as above and fitted to the bottom
of the desk or elsewhere where necessary to give the pitch or angle.
