Archibald Thomas Flower, Glenside, Pa. (Queen St. and
This invention relates to a spreader bar and bridle for 10 legs exert a tension on the bars to move the bar 5 up

wardly while moving-the bar 6 downwardly thus moving
It is an object of the invention to provide a spreader
the slots 7 and 8 into non-registering position as shown
composed of superimposed bars having cooperating slots
in their longitudinal edges to receive conductor wires
and a spring bridle connected to the bars and normally
moving the bars in opposite directions to retain the wires
in the slots.
A further object of the invention resides in connecting
the legs of a spring bridle to a pair of superimposed
spreader bars having slots in their longitudinal edges to
receive conductor Wires so that the legs of the bridle
exert a spring tension on the bars to move the bars in
opposite directions to position the slots to a non-register
ing relation to. retain the wires in the slots, said bars
having means to receive and retain the legs of the bridle
in expanded position when the bars are moved to bring
the slots in register for inserting or removing the con
ductor wires.
This invention is an improvement on the spreader bar
disclosed in my co-pending application ?led November
23, 1960, Serial No. 71,323.
Other objects and advantages of the invention will be
apparent during the course of the following description.
In the accompanying drawing forming a part of this
speci?cation and in which like numerals are employed
to designate like parts throughout the same.
FIG. 1 is a perspective view of the spreader bar and
in FIG. 2.
When it is desired to insert or remove the
conductor Wires from the slots 7 and 8, the bars 5 and
6 are moved longitudinally in opposite directions until
the notches 19 of the guide slots 17 and 18 register where
upon the hooks 16 of the bridle legs 15 are moved into
the notches 19 thereby holding the bars with the slots
7 and 3 in register. Upon disengaging the hooks from
the notches 19, the tension of the spring legs of the bridle
will move the bars to a locking position and prevent
accidental displacement of the conductor wires from the
slots 7 and 8.
In erecting the spreader, the bars 5 and 6 are moved
relative to each other to bring the slots of the bars into
register and then the hooks 16 of the bridle legs are en
gaged in the notches 19 of the guide slots to hold the bars
5 and 6 against movement While inserting the conductor
wires in the slots. After the wires are inserted in the
slots, the hooks on the ends of the bridle legs are moved
from the notches 19 into the guide slots 17 and 18 and
the spring tension of the bridle legs then moves the bars
5 and 6 in opposite directions to engage the wires in the
branch 10 of the slots 7 thereby locking the wires in
position.
Having thus described my invention, I claim:
