FIG. 6 is an enlarged fragmentary view on a line corre

FIG. 7 is an enlarged fragmentary view on a line cor
responding to line 7—7 of FIG. 3 illustrating the ballast
working disc unit in work position by full lines and in
lower scraping edges 11 in substantially the same plane.
The inner and outer ends of these blades are ?xedly
secured to the inner and outer longitudinal members
'5 and 6 and they are braced by the cross strut-s 12 and
13. Thus arranged the blades constitute cross members
for the longitudinal members and they are disposed sub
stantially centrally relative to the ends thereof. It will
be understood that one blade ‘serves as a scrape-r when
55 the carriage is driven in one direction and the other
blade when driven in opposite direction.
The outer longitudinal member 6 is provided with a
discharge opening 14 which opens to the lower edge there
of.
The purpose of this is that frequently there is an
60 excess of ballast, that is there is more ballast than is
required to produce the desired grade of the ballast shoul
' ders at the outer ends of the ties.
The combined scraper and closure member 15 for this
opening 14 is hingedly mounted at 161 so that it may be
65 adjusted to opening and closing ‘positions, as shown in
FIGS. 1 to 4 inclusive or to scraper position, as shown

To further facilitate the spreading and working of the 40 The members 8 are provided with inwardly and up
charged through the opening in the outer longitudinal
ballast by the blades the plows or harrow members are
provided at each side of the main scraper blades and in
spaced relation thereto. One ballast working means, il
lustrated at the left end of FIGS. 3 and 5 and further de
tails in FIG. 6, comprise the shaft 30 mounted on the
support member 31 on the inner sides of the longitudinal
members 5 and 6. An elongated hub 32 is rotatably
mounted on this shaft or cross rod 30 and the plow
blades 33 being mounted on the hub 32 to form a unitary
assembly, the blades being provided with removable
wear or face members 34.
They are provided with up
wardly projecting arms 35 which supportingly engage the
cross piece 36 when the blades or plows are in working
position.
The blades or plows engage the underside of the cross
piece when in retracted position and are held in that re
tracted position by the removable cross rod 37. The
angularly disposed portion of these plows is disposed on
the underside of the bearing and clamped thereon by the
clamp members 38, see enlarged detail of FIG. 6.
It will
be understood that there are some conditions in which
these plow blades are not required and in other condi
tions they are highly desirable.
To further work up and distribute ballast a ballast
working unit is provided at the other end of the ballast
working means. This comprises the support members 31
mounted in alignment on the inner sides of the members
5 and 6 to receive an axle 30 not shown in detail for the
wardly projecting forks 56 which embrace the uprights
9 and are connected by the pivots 57 to the plungers 58
projecting from the hydraulic cylinders 59 which are sus
pendingly mounted at 60 on the uprights 9. These up
rights have vertical slots 61 through which the pins 57
project with the yoke arms 56. To increase the lateral ad
justment of the scraper units beyond the adjustment of the
support members 52, the supporting arms 8 are provided
with a plurality of longitudinally spaced holes 610 adapted
to receive the connecting bolts 62, see particularly FIGS.
9, 10 and 11. One of the purposes of this adjustable
mount-ing, as stated, is to permit adjustment of the scraper
unit to the position conventionally indicated in FIG. 11
to remove ballast from the ends of the ties and thereby
permit or facilitate the removal and the replacement of
ties. It is of advantage for this purpose to position the
combined scraper-closure member 15 in its inner or
scraper position illustrated in FIG. 5, thus permitting the
discharge of the ballast from the ballast scraper working
unit. The positioning of one or both of the ballast work
ing units in ballast working position also greatly facilitates
the removal of the ballast from the ends of the ties.
We have illustrated and described our invention in a
highly practical embodiment thereof. We have not at
tempted to illustrate or describe other embodiments or
adaptations which are possible and are contemplated for
particular adaptations, as it is believed that this disclosure
will enable those skilled in the art to embody or adapt the
invention as may be desired.
