Starting
about 1888, they were equipped with a pneumatic release (brass
cylinder), and another name, Scovill's Time and Instantaneous Shutter,
was born. The example above shows all the features of the
Universal Safety Shutter and the pneumatic release of the Time
and Instantaneous Shutter.

Notes:
Scovill's Safety Shutter and
Scovill's Universal Safety Shutter were advertised on the same
page, the Universal model costing over twice as much as the
non-Universal. They did not appear in 1886 catalogs, the Scovill
catalog of April 1887 being their first appearance.
Both
models had a manner of braking the dropping slide, which prevents the
jolt made as a drop shutter suddenly stops dropping. The shutter
is equipped with two (sometimes one) brass spring bent outward from the
shutter, and a brass rod across the top of the shutter. After the
slide has cleared the exposure area, the springs rub on the rod, braking
the motion. The further the drop slide proceeds, the more the
braking, until finally the hooks at the end of the springs catch on the
rod.
The
Universal Safety Shutter, differs from the Safety Shutter
had a unique way of adjusting the length of the exposure by moving one
of the wooden panels, securing it by means of the perforated brass
piece.
