Improvements in School Desks and Seats.
JAMES DICK BENNET Cabinet Maker, 29 Dalmarnock Road Glasgow do hereby
declare the nature of this invention to be as follows:-
The desk has an adjustable seat. It can be set to suit any heights of staging from
two inches to nine inches; having slot, also holes every half inch for bolts, the slot
being so constructed as to take the strain off the bolts. The advantage of this desk is,
that in schools where there are graduated galleries in the same room, eis. 4", 5" 64".
7" and 7"; the desk can be adjusted to the proper height between seat and top of
desk. Also it has a separate piece to attach to the holes to increase the width of the
back, as the seat is lowered. The arm for the folding desk is protected by a flange
to prevent the fingers being pinched. The slot to receive the slate is so constructed,
that the slate is held two-thirds above the top of desk, when used for copying
exercises by a guide, which also serves to conduci the slate to its proper position when
not in use.

COMPLETE SPECIFICATION.
Improvements in School Desks and Seats.
I, JAMES DICK BENNET Cabinet Maker of No. 40 Tenant Street, St. Rollox (late of
29 Dalmarnock Road), Glasgow, 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 the metal supports and framework of school desks and
seats, either combined or separate, and has for its objects --1st to render school desks
capable of being raised or lowered to suit varying requirements; 2nd to render seats
capable of being raised or lowered to suit varying requirements; 3rd to obviate the
ungainliness, in form and size, of combined (metal) desk and seat supports; 4th to
render such metal supports more generally serviceable than those hitherto in use.
The desk has, combined with it, an adjustable seat which can be set to suit different
heights of gallery staging, from two inches upwards; having a slotted framework
containing numerous bolt holes, about half an inch apart from each other, for the
reception of bolts; each slot being so constructed as to take the strain off the bolts.
The advantage of this desk is that, in schools where there are galleries with graduated
steps, having risers" of varying heights such as 4, 5, 6, 7 and 74 inches in one
gallery the desk can be adjusted to any required height between the seat and top of
desk by means similar to those for regulating the height of the seat.
I effect the aforesaid objects by means of the mechanism which is illustrated in the
accompanying sheet of drawings, in which
Figure 1, is an elevation of my improved desk and seat combined;
Figure 2, is an elevation of my improved seat combined with a folding desk;
Figure 3, is an elevation of my improved seat only;
Figure 4, is a perspective view of an adjustable bracket piece ;
Figures 5 and 6 are sectional views shewing the method of attaching the adjustable
bracket pieces to their associate framework.
In carrying out my invention I construct my improved metal support, marked H,
J and K, Figs. 1 to 3 (for either a desk or seat) with a slot, groove, channel or panel
on each, either or any side of it such as that marked a, Figs. 1 to 6, which part is
pierced with numerous bolt holes (marked b) for fastening purposes, and 1 form the
'

page_text: bracket c, Figs. 1 to 6, suitably for being fitted upon the metal support as shewn in
Figs. I to the part marked c, Fig. 4, (pierced with bolt holes marked ²) fitting
into the slot a, and e², c³, being fitted closely upon the flanges a².
Each of the said brackets is united to the support with bolts, pins or screw-pairs
marked 3, Figs. 1 to 6, or such like mechanism, and may be made either with or
without a hinged part d, or d³, jointed at 2 for folding back as shewn by the
Figs. 1 to 4.
The bolt holes, marked b, are made sufficiently near together to enable the bracket
parts to be fixed at any elevation required. The desk marked e, in Figure 2 is
provided with a seat (Fig. 3) which forms no part of its own structure whilst the
seat. Figure 2, is designed for use in conjunction with a desk occupying a place to
the right of its position upon the drawing. This form of combined desk and seat
support is less cumbersome and more generally serviceable than the combined desk
and seat support in ordinary use; in which, cach desk support is united to its own
seat support; nevertheless my adjustable bracket mechanism, either with or without a
hinged arm, d, for folding, is designed for application to the old forms of desk and
seat supports as well as to that shown in the accompanying illustrations.
In Figure 1, I have shewn my improved (adjusting) mechanism applied to the
upper part of a desk support, for raising and lowering the desk, and to the lower part
of it for raising and lowering a seat; and in Figure 3I have shewn the said
mechanism applied to a seat support only.
Figures 2 and 3 are representations of my improved desk and seat fitted upon a
gallery marked V: V of graduated heights or " risers."
In carrying out my invention it is not essential that the exact forms shewn in
Figures 4, 5 and 6 should be adhered to provided that the bracket. c, and supports H,
J and K contain the reciprocal parts of a male and female joint, held together by one
or more screw-pairs, or their equivalents.
When it is desired to alter the elevation of my improved desk (or seat) the bracket e.
must be disconnected from the support (H, Jor K) and moved higher or lower as
required and re-fastened with the mechanism before described.
1 am aware that, previous to my invention, school desks have been made which
were combined with mechanism for raising and lowering them to varying altitudes.
as well as to varying angles; it will therefore be understood that I do not claim such
combination, broadly, as my invention.

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
First. A metal desk supporting framework combined with detachable bracket
pieces, all constructed and operated substantially as herein described and shewn and
for the purposes specified.
Second. A metal seat supporting framework combined with detachable bracket
pieces all constructed and operated substantially as herein described and shewn and
for the purposes specified.
Third. A combined metal desk and seat supporting framework having detachable
bracket pieces, c, all constructed and operated substantially as herein described and
shewn and for the purposes specified.
