cess to produce slack in the chain when en-
gaged with the seats to permit of the wrench-
head being moved across the work until the
latter becomes wedged between one of the
5 jaw portions and the chain.
3. A wrench comprising a bifurcated head
having its working face at opposite sides of
the bifurcation provided with jaw portions,
there being a work-receiving recess formed
ro in each side of the head between the opposite
jaw portions thereof, one end of the head
having corresponding seats at opposite sides
of its bifurcation, and a chain loosely con-
nected within the bifurcation of the head at
15 the other end thereof and provided at oppo-
site sides with series of lateral projections for
successive engagement with the seats, the
projections being spaced relatively with re-
spect to the depth of the work-receiving re-
20 cess to produce slack in the chain when the
work is in the work-receiving recess and the
chain is engaged with the seats to permit of
the wrench - head being moved across the
work until the latter becomes wedged be-
25 tween one of the jaw portions and the chain.
4. A wrench comprising a head having its
working face provided with opposite jaw por-
tions and also provided with a handle-receiv-
ing seat disposed at an angle of substantially
30 forty-five degrees to the working face of the
head, a flexible work-embracing element con-
nected to one end of the head and having a
series of connections with the other end there-
of, and a handle for interchangeable engage-
35 ment with the seat of the head.
5. A wrench comprising a head having a
working face and also provided with a han-
dle-receiving seat disposed at an angle of
substantially forty-five degrees to the work-
40 ing face of the head, a flexible work-embrac-
ing element connected to one end of the head
and having a series of connections with the I
other end thereof, and a handle for inter-
changeable engagement with the seat of the
15 head.
6. A wrench comprising a head having its
working face provided with a jaw, a work-
receiving recess and a handle-receiving seat
disposed at an angle of substantially forty-
5o five degrees to the working face of the head,
a flexible work-embracing element connected
to one end of the head and having a series
of connections with the other end of the
head, and a handle having one end set at an
55 angle of substantially forty-five degrees to
the longitudinal axis of the handle for inter-changeable engagement with the handle-re-
ceiving seat.
7. A wrench comprising, a head embody-
ing a plurality of plates parallel at each end
and the ends connected by a lateral integral
curve, and each having at each end oppo-
sitely-inclined work-engaging teeth, and
means for holding the work in engagement
with the teeth.
8. A wrench comprising, a head embody-
ing a plurality of plates parallel at each end
and the ends connected by a lateral integral
curve and each having at each end oppo-
sitely-inclined work-engaging teeth and hav-
ing transverse concavity formed at the
curves and registering with each other and
means for holding the work in engagement
with the teeth.
9. A wrench comprising, a head embody-
ing a plurality of plates convex along their
edges and parallel with each other at each
end and the ends connected by a lateral inte-
gral curve and each having at each end op-
positely-inclined work-engaging teeth and
having a transverse concavity formed at the
curves and registering with each other and
means for holding the work in engagement
with the teeth.
10. A wrench comprising, a head embody-
ing a plurality of plates convex along their
outer edges and parallel with each other at
each end and the ends connected by a lateral
integral curve and each having at each end
oppositely-inclined work-engaging teeth and
having a transverse concavity formed at the
curves and registering with each other a
chain pivoted between the plates at one end
and arranged to embrace the work and means
for securing the chain between the plates at
their other ends.
11. In a wrench a head formed of two
toothed plates, a chain pivoted at one end
between the plates and having spaced studs
outstanding laterally therefrom lugs offset
from the plates forming registering notches
proportioned to receive alined studs and'
curved shoulders disposed circumferentially
to the notches as centers and proportioned to
seat adjacent alined studs.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in
the presence of two witnesses.
