as shown in Fig. 5.
A tread switch blade 21 is mounted in those

,The blade 28 is connected by means of in
sulating spacers 32 with a second blade 33 and
a third blade 34 so that all three will move in
unison with the member I2. A normal ?ange ~
25 forces the blade 28 outwardly to close a cir
cuit with a contact 35. Further outward moVe?'
ment, such as caused by a high ?ange, forces
the third blade 34 to close a circuit with a con
tact 36.
A broken ?ange allows the member IE to swing
inwardly and upwardly under the in?uence of
its spring 22 so that the. blade 33 will close a
circuit with a contact 31. The contacts 29 and
31 are connected together by means of a jumper -
wire 38, and the contacts 3| and 35 are similarly
interconnected by means of a second jumper
wire 39.
The contact 38 is connected to a relay sole
noid, which will be herein designated the ?hol
low tread? relay 40, by means of a conductor"
4|; the third switch blade 34 is connected to a
similar solenoid, herein designated the ?high
flange? relay 42, by means of a conductor 43;
operates the armature 48 of this relay to close
circuit 55 to give any desired ?broken tread?
signal.
The rim of a hollow tread forces the vertical
leg of the member || still further from the rail
and causes the blade 21 to contact the contact
30. This closes a circuit from the battery 59
through the negative lead 52, the blade 21, the
contact 3|], the conductor 4|, through the ?hol
low tread? relay 49, thence back to the battery
through the positive lead 5|, operating the arma
ture 48 of this relay to close circuit 49 to give
any desired "hollow tread? signal.
In Figs. 6 to 11, inclusive, an alternate form
of the invention is shown embodying the same
principle of mechanical contact devices operated
by the wheels controlling electrical signal cir
