member comprising a vertically extending carrier plate
mounting plate, a carrier plate, end resilient stop means
having an engine bearer on its inner face and an out
and vertical movement restriction means that are detach
able, they can be assembled as a unitary structure for
with the carrier plate having a bearer adapted to rest
application to or removal from the center sill member, Gi
and also for adjustment lengthwise on the sill. Upon
removal of bolts 92, 100, 120 and 132, the mounting units
M can be shifted longitudinally to permit the associated
engine leg 82 to freely pass thereby in a vertical direction.
To dismount the engines A and B, they are jacked up
with bolts 92 removed to permit longitudinal movement
of the mountings into either engine receiving position
or engine removal position. During this operation, the
locomotive is preferably located over a pit in which suit
able jacks can be arranged for raising and lowering the
main engine. The engines are mounted to float on rub
ber so that operational vibration will be substantially
damped without transmittal to the underframe.
The invention may be modified in various respects as
will occur to those skilled in the art and the exclusive use
of all modifications as come within the scope of the ap
pended claims is contemplated.
What is claimed is:
1. A mounting for carrying an engine on a frame com
prising a vertical carrier plate with a top flange having
one end turned down, a mounting plate parallel with the
vertical carrier plate and having a bearing extension
adapted to be detachably secured on the frame, rubber
means between and secured to said plates, an abutment
adjacent said downturned flange end adapted to be de
tachably secured on the frame, and rubber means se
cured to and between said abutment and said downturned
end portion of the carrier iiange.
2. A mounting for carrying an engine on a frame
member comprising a vertically extending carrier plate
having an engine bearer extending from the inner face
and an outwardly extending top ñange, a mounting plate
parallel to the carrier plate having an intermediate ont
wardly extending bearer adapted to be secured on top of
the frame member, rubber means between and secured 40
to said plates, a bracket secured to the outer face of the
mounting plate above the mounting plate bearer, and
means associated with the top flange of the carrier plate
and the bracket for snubbing vertical movement of said
carrier plate.
3. A mounting for carrying an engine on a frame
wardly extending top ñange, a mounting plate parallel
on and to be secured on said frame member, said mount
ing plate being spaced from said carrier plate top ñange,
rubber means between and secured to said plates for
floatingly supporting the carrier plate, a bracket on the
mounting plate and resilient snubber means between the
carrier plate and bracket resisting vertical movement of
said carrier plate, the top of the mounting plate serving
as a stop for the carrier top flange in the event of failure
of the rubber means.
4. The combination of center sill frame members
spaced to receive an engine therebetween, a plurality of
similar mountings each comprising a vertically extending
carrier plate having an inwardly extending engine bearer,
a mounting plate having a vertically extending portion
parallel with the carrier plate and an outwardly extend
ing bearer slidably mounted on the center sill frame
members, rubber means between and secured to the paral
lel portions of the plates, detachable means for securing
the mounting plate bearers to the sills, spacer means
between the vertical portions of the mounting plates and
the adjacent center sill frame members and a guide
rest secured to the bottom of the sills for receiving the
bottom of the mounting plates and spacer means.
