40ranged within these grooves are a plurality
of roller bearings 16. The roller bearings
are of such diameters that their surfaces
will be in a plane with the outer surfaces
of the shaft to which they are applied and
the openings in the rollers 14 will be .of a
size to loosely receive the shafts. With
this construction it is evident when the roll-
ers are positioned as shown in Fig. 3 they
will revolve on the bearings 16. In order to
prevent endwise movement of the rollers on
the shafts spacing sleeves 17 are employed.
These members are preferably formed of
pieces of metallic tubing of a size to nicely
receive the shafts 11 and in the arrange-
ment of parts these sleeves are. designed to
be placed between the outer-most rollers and
side walls of the sections and between the
adjacent rollers on each of the shafts. With
this construction it is evident that the roll-
ers will be held in spaced relation on the
shafts and at the same time will be free to
rotate on their bearings.
Reference now to Fig. 1 discloses the fact
that located on the outer sides of the track
rails and bearing on the cross-ties are sec-
tions 18 and 19 similar to the sections 5 and
6. The sections 18 and 19 are provided with
transverse shafts 20 similar to the shafts
11 and also with rollers 21 similar to the rol-
lers 14. The said shafts 20 have annular
recesses and roller bearings for the rollers
21 similar to the construction already de-}
scril)ed for the sections 5 and 6. The sec-I
tions 18 and 19 are hingedly united at their
highest points by pintles 10' and the lower
or free ends of their side walls are connected
by bearing plates 22 and 23, similar to the
bearing plates 12 and 13 and performing
the same function as that recited for the
said bearing plates 12 and 13.
Owing to the fact that the side walls ofthe sections are disposed longitudinally of
the track the shafts are transverse with re-
spect to the track and the inclines formed 45
by the sections are longitudinal of the track
so that should an animal get upon the guard
and slip thereon the animal will move lon-
gitudinally of the track and will not be
likely to get its hoofs caught between the 50
sides of the sections and the track rails.
Furthermore, owing to the fact that the
sections are pivotally connected together,
their angle of inclination may be varied as
may be required by the varying spaces be- 55
teen the ties on which the bearing plates
rest and are secured, and hence the guard
may be adjusted longitudinally as may be
required by the extent of the space between
the ties on which the guard is mounted. 60
From the foregoing it can be seen that I
have provided a device which is exceedingly
simple in structure and comparatively inex-
pensive to manufacture, embodying few
parts and these so arranged that the danger 65
of derangement will be reduced to a
minimum.
What is claimed is
A cattle guard consisting of a pair of
frames having spaced overlapping hinge 70
lugs at their meeting ends, a single pintle
passed through the spaced hinge lugs and
hingedl1y connecting the fra. mes together,
spaced shafts having their ends journaled in
the sides of the frames, and overlapping 75
rollers arranged on said shafts in staggered
relation.
In testimony whereof, I affix my signature
in presence of two witnesses.
