By lifting the front of the seat or desk, it can be easily moved forwards & back-
wards, & can be secured in two or more positions without the use of pegs, pins, &c.
This invention consists of pairs of castings, one of which is fixed or attached
to top of standard of seat or desk, and it has an elongated hole with teeth at
intervals the other casting screws on the underside of seat or desk, and it has a
lug or hook which works in casting fastened to standard.

JOHN WILBURN, 54, St. Leonard's Road, Rotherham, Pattern Maker, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:
This invention consists of a sliding seat or sliding desk, so that the pupils may
be in a proper position for writing, and so prevent twisted spines, cramped chests,
and other deformities, and this invention can be adapted to fixed desks in present
usc.
This invention consists of pairs of castings, A, B (Figs. 1, 2, and 3). The one
marked A is fixed or attached to top of standard J of seat or desk K, and it has an

page_text: elongated hole C with teeth or projections H, H at intervals and groove I. The
other casting B screws on the underside of seat or desk K, and it has a lug, or
hook, or other projection 1), which works in elongated hole Ċ in casting A fastened
to standard J. This casting B has a guide rail F with a flange G, so as to guard
against the seat or desk K tilting up.
The action is the following:-
By lifting the front edge of seat or desk K (with the casting B screwed on the
underside of K), drawing it forward, and then dropping it, it brings the lug or
hook or projection D on casting B into the teeth or projections H, H and groove I
of casting A fastened to top of standard J, and prevents the seat or desk K from
slipping back.
The studs or projections E, E in casting B prevent the seat or desk slipping
forward, so that it is self-locking.
The guide rail F with flange G in casting B guides and guards the seat or
desk K tilting up, and keeps it at right angles to the standard J.

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. An invention for bringing forward seat or desk of fixed desks, so as to give
the pupils an upright position.
2. Self-locking action in this arrangement.
