This invention relates to lids for railway journal boxes.
An obstacle long confronting the development of jour

Spring 15 against the hinge lug 3, any reduction in the
force exerted by the spring on the hinge lug will reduce
the outer wall 33 thereof, the fulcrums 4o and 41, to
ena-ble them additionally to prevent the lever 24 from
the closing force on the cover. Thus, as opposed to an
rotating out of its vertical position about the stem 34 of
the eyebolt 32, each conveniently may be formed by a
preferably cylindrically convex rib or ridge 42 outstand
ing from and extending horizontally or transversely of
ordinary lid in which the static closing force ñxes the
opening force required to be applied to the cover to open
the lid, the closing force on the cover 5 of the lid of this
invention is progressively reduced or decreased with in
crease in the force on the lever means 24 by reduction
in the force exerted by the spring 15 on the hinge lug 3,
with the result that the outward force required to be ap
plied to the cover through the lever and hood to open
the lid is far less than the static closing force on the cover.
Not only does t‘ne lever means 24 effect this reduction in
the closing pressure of the spring 15 on the cover 5 with
out appreciable movement prior to opening, but it main
tains this reduction as the lid is swung between closed and
open positions by moving relative to the hood 1 or other
part of the lid on which it is fulcrumed. It is this prin
ciple that is utilized in the lid of this invention to reduce
a static closing force far in excess of that employable in
an ordinary lid to the point at which the lid may be
opened by a force within the required 25-30 pound range
without extending the lever means beyond the vertical
contines of the ordinary lid and without requiring special
handling either during opening or closing or after the
lid is closed. Specifically, it is possible in a lid of the
relative dimensions of the illustrated embodiment to in
one of the members and normally seating in a corre
spondingly extending and concave groove 43 in the con
fronting surface of the other member, the ribs here being
formed on the underside 44 of the lever 24 and the mating
grooves in the outer surface 26 of the hood 1.
Respeetively at or adjacent and downwardly of the
upper end 2S of the lever 24 and together bracketing or
straddling the stem 34 of the eyebolt 32 and the aperture
36 in the hood 1 through which the stem projects, the
upper and lower fulcrums 4i) and 41 enable the lever to
apply an outward retracting or pulling force on the upper
end 1S of the spring 15 and so decrease the force exerted
by the spring on the hinge lug 3 incident to and without
change in the normal motions by which the lid is swung
open and closed. Thus the lever 24 will fulcrum about
the upper Íulcrum 49 on opening and the lower fulcrum
41 on closing, acting in the iirst instance as a second
class lever and in the second as a first class lever. In
each case the force exerted by the spring 15 against the
hinge lug 3 is reduced by an amount equal to the force
applied to the lower end 28 of the lever 24 multiplied

Centered laterally or transversely on and
extending longitudinally of the hood 1, the lever 24 pro

preferably below the straight lower edge 27 of the pre

of the lever 24 conveniently is ñared or widened adjacent
its lower or free end 2S to provide a readily grippable >
handhold or handle portion 29. The lever 24, as a Whole,
may be of any cross-section suitable for rigidity, that
shown, except for its handheld 29, being of channel sec
tion with a central web 30 reinforced by side flanges 31.
The connection between the upper end portion of the
lever 24 and the hood 1 is made by a link or connector
32 which at the same time connects or links the lever to

is bonded to the inner face 45 of the cover 5 a “Urethane”
or like resilient sealing gasket 46, which in the closed
position of the lid seats against the lid face 6 on the
journal box.
While the lever 24 reduces the force applied by the
spring 15 to the hinge lug 3, it is neither designed nor
intended to counterbalance that force, so that the roller
19 at all times remains in contact with the periphery 20
of the hinge lug.
Nonetheless, relative movement be
tween the lever and both the hood 1 and the retractor or
eyebolt 32 will occur, as the roller 19 is displaced out
wardly toward the front Wall 38 of the hood in rolling or
moving, as the lid is opened or closed, between its closed
position on the front face 35 of the lug and the latter’s

However, this would have the disadvantage of reducing
correspondingly the maximum force exertable by the
spring against the hinge lug 3 with attendant reduction
in the static closing force on the cover 5. It therefore is
