Year: 1885

page_text: I ROBERT LEGG of the City Engine Works Eagle Wharf Road in the County
of Middlesex Mechanical Engineer do hereby declare the nature of this invention
to be as follows:-
This invention has for its object improvements relating to the stall boards of
shop windows.
I make these stall boards moveable in such manner that together with the goods
arranged thereon the stall board may be run back away from the window thereby
admitting of the window being more conveniently cleaned and of more ready
access to the goods.
I for this purpose mount the stall board on wheels and provide rails along which
these wheels may run from and towards the window. On the axle of one pair of
the wheels carrying the stall board I provide a worm wheel and with this worm
wheel a worm engages.
The axis of the worm extends to the rear and is there
provided with a crank handle.
By turning this handle the stall board is readily and steadily withdrawn from
the window or advanced towards it as may be desired.
Or the handle may be upon a shaft turning in bearings connected with the stall
board and having a screw thread cut upon it; this screw then engages with a
stationary nut and so on turning the screw movement is imparted to the stall
board.
Dated this 1st day of December 1885.

Figure 1 is a plan, Figure 2 is a vertical section and Figure 3 is a rear elevation
with parts in section of a stall board arranged in accordance with my invention
and other parts in connection therewith.
a a represent the side walls of a shop-b the window in front and at the side of
the entrance-c the door, d the floor line, e the ceiling, f the fixed counter and f¹ a
hinged flap forming a continuation of the same but moveable to provide a passage
way from the back to the front of the counter, gg is fixed shelving; all these parts
are arranged in an ordinary manner, and admit of variation and are shown only
for the purpose of illustration, h h are grooved rails sunk into the floor, i is the
platform of the stall board, k are bearings on the under side of the platform
which receive the necks of the axles l l. m m are flanged wheels fixed on the axle
and standing on the rails h h. n is a worm wheel fixed on one of the axles . o is
a worm carried in bearings at the end of the platform, it has a square upon it at
its binder end to receive a crank handle or it may be a hand wheel. p. p are
sliding shutters of glass at the back of the stall board; they can be lifted out when

page_text: the stall board is to be moved back from the window. q. q is a stationary glazed
frame forming the top of the show case and serving to protect the contents
from dust.
The stall board is run back from the window when it is required to clean the
window or arrange the contents of the show case; for this purpose the counter
flap f¹ is thrown back, the glazed shutters p. p. are removed and then by the
handle applied to the squared end of the worm o the wheels are put in motion and
so the structure may be run back with a slow and steady motion so quietly that
there is no risk of the goods upon it being overturned or deranged. In some cases
the whole of the glazing of the show case may be mounted on the stall board so
as to move with it. In place of the worm wheel n and worm o. I may provide
bearings beneath the platform i, at the points marked r. r. in Figure 1 and
mount in these bearings a shaft having a screw thread cut upon it. I then also
provide a standard fixed to the floor of the shop at the point marked 8 and this
standard carries a nut through which the screw works.
The shaft is squared at its end to receive a crank handle or hand wheel, and
when the shaft is turned by this means the stall board is moved along the rails.
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 :-
1. The combination substantially as described of the parts h. i. k. l. m. n and o.
2. A stall board provided with wheels beneath the platform and guide rails on
which the wheels run and gear for imparting a slow and steady motion substantially
as described.
3. The arrangement of the stall boards of shop windows substantially as
described and illustrated by the annexed drawings.
