The drawings illustrate the preferred form of
construction by which the several objects of this
invention are accomplished. In this connection
a suitable mounting plate is indicated at I0. Po
sitioned atone end of this mounting, plate is a
'U -shaped bracket | |, the end portions |2 of which
are, arranged in parallel relation with respect to
each other to provide spaced bearings for a driven
shaft | 3 extending through the mounting plate
l0 and extending vertically thereabove. The lower
end portion of this shaft I3 is slotted as at I5
for the reception of a key l6 carried by the driv
ing. shaft H, which driving shaft I‘! is rotated
by a suitable driving power, such for example,
an electric or spring motor (not shown).,. The
major length of this shaft I3 is provided with a
longitudinal slot l8 for reasons hereinafter set
forth. Positioned upon the shaft l3 and ?xed
thereto by means of a suitable set screw l9 and
located adjacent the lower end portions l2 of
the bracket | I is a collar 20.
posed between the pulleys as shown. The top
and bottom pulley of the pulleys 34, are spaced
25
from the end portions ‘3| of the bracket 30‘ by a
suitable bushings 36. These pulleys 34 each com
prise grooves '31 in which work the ‘continuous
ribbon-like belts 29.
V
‘
_
The lowermost of "the discs 2| (as shown in
Fig. 3)'rests' upon the collar 20 ?xed to the shaft
| 3 ‘by the set screw t9.
'
The arrangement is such that when the shaft
|3 is rotated by the shaft H, the pulleys 22,
resting'u'pon the driving discs 2|, will rotate with
the discs 2| except when prevented from doing so
in a manner now to be described.
'
" Fixed to the mounting plate It) is a supporting
bracket 38. Carried by this bracket 38 are a plu
rality of independently operated solenoids 39 each
comprising a solenoid shaft 40 adapted to be pro-L
jected outwardly toward the pulleys 22 by any
suitable or well-known means successively en
gage the ‘ratchet gears 28 of the pulleys 22 to mo
mentarily hold one of ‘the pulleys against rotation
'- witli its respective drivin'gor supporting‘ disc 2|.
This successive engagement ‘between the sole
noid shafts‘llt' and the ratchet gears 29 may be
accomplished in any suitable manner,‘ butfor the
purpose of illustration I have shown in Fig. 6 a
circuit diagram ‘capable of this accomplishment.
In this connection, 4| indicates a motor-driven
switch arm, the motor being indicated at 42 and
arranged in an electric circuit 43, in which cir

of electric energy 48.
The arrangement is such that upon engage

'
object carried thereby will likewise momentarily

jects to advance forward of the racing object mo
