desired, without interference, the ?anges 4| of

In Figs. 4 to 8 inclusive, a modi?ed form of
the invention has been disclosed which is very
similar to the prior form distinguishing merely in
the fact that means havelbeen provided for hold
ing the discs ll, l8 and 19 from turning, and
this means is adjustable to free the discs so that
they may be turned individually, or as a unit.
This means includes a slide plate 4-9 engaged
across the back of the indicator 21 and having
edge portions 4! engaged around the edges of the
indicator 2?, and engaging cutouts 62 formed in
- the edge of the indicator 2'! by which the slide
plate 40 is limited to move a short distance up
wards and downwards.
Leaf springs-.43 are mounted upon the bottom
of the support block as and engage the top edge
of the slide plate at normally urging it into its
bottom position. The slide plate 40 has window
openings 44 which are alignedv with the window
openings‘ 28. of the indicator 2'! so as not to in
terfere with viewing the several discs through
the window openings.
A plunger 46 is provided with each of the discs
l1, l8 and I9 and each is slidably' mounted
through a tubular’ socket ill ?xedly mounted on
the ‘back of the slide plate til. The stationary
indicator 2'! is formed‘ with small ventical slots
48 through which the plungers 46 pass.‘ These
plungers 46 are square, in transverse cross sec
' tion, and the sockets 41 are similarly shaped,
limiting the plungers to slide inwards and out~
wards, and restraining them from turning. Each
plunger 45' is provided with a knob t9 by which
the plunger may be pressed inwards. Each

claim as new, and desire to secure by United
