which extends over the upper and lower
faces of the reach and forms a bearing for
a collar-like device 26, the collar having
preferably square flanges 27 at its ends and
bearing upon the opposite side faces of the
straps. A strap 28 which is substantially a
duplicate of the strap 25 is connected to the
opposite faces of the movable reach mem-
ber 18 and forms a bearing for a collar 29
io having bearing flanges 30 and is a substan-
uial duplicate of the collar member 26 with
its. flanges 27.
Extending inwardly from the collar 26 is
a half roller member 31, while a similar half
S5 roller member 32 extends inwardly from
the collar 29. The members 31-32 bear
against each other face to face their whole
length as shown in Fig. 1. At its center the
half roller member 31 is enlarged as shown
2o at 33 with a transverse mortised opening'
formed through the enlargement, while a
similar enlargement 34 is formed upon the
roller member 32 and is provided with a
similar mortise, the two mortises designed
25 to receive the inner end of the tongue repre-
sented at 35. A pivot pin 36 extends
through the enlargement 33 and its mortise
and likewise through the tongue 35, while
a similar pin 37 extends through the en-
30 largement 34 and likewise through the'
tongue 35. By this means the tongue is
coupled to the roller members and when
the tongue is moved laterally by the team
the roller members will be shifted longitu-
35 dinally as will be obvious. The collar 26 is
provided with a transverse aperture indi-
cated at 38 and designed to receive the outer
end of the collar member 32,. while a simi-
lar aperture 39 is formed in the collar 29
40 to- receive the outer end of the roller mem-
ber 31. The roller members are thus guided
in their movement when the tongue is moved
laterally for "cramping " the vehicle. This
movement of the tongue it will be obvious
45 causes the movable reach-member 18 to
swing upon its pivot 23, the object to be
hereafter more fully explained. A swiveled
axle is connected to each end of each of
the bolster members 10, one for each of
50 the bearing wheels, and as these axle de-
vices are precisely alike, the description of
one will suffice for all. The swiveled axles
are represented at 40 and are formed with
an enlargement 41 at the inner ends extend-
55 ing vertically, each enlargement being pro-
vided with an arm 42 at its ends which bear
upon the upper and lower faces of the bol-
ster member 10, and extending downwardly
through the bolster members 10 and 11 and
60 the arms 42 is a pivot bolt 43. By this
means the axles are mounted to swing lat-
erally upon the bolsters and firmly support-
ed relative thereto.
Each of the upper head members 41 is
65 provided with a lateral projection 64, andcoupling the members 64 of the rearward
axles is a rod 65, while a similar rod 66
couples the projections 64 of the forward
pivoted axles. Connected to the projection
64 next to the movable reach member 18 is 70
a rod 67, while a similar shorter rod 68 is
connected to the arm 64 of the forward
swivel axle next to. the movable reach-mem-
ber 18. The rods 67-68 are pivotally united
at their inner ends, as shown at 69-70 to: 75
the movable reach-member 18.. By this ar-
rangement it will be obvious that as the
reach-member 18' is moved, upon its pivot 23,
as before described, the pivot axles will be
swung' correspondingly to cause the- wheels 80
to " cramp " as will be obvious.
What I claim as new is:-
1. In a vehicle, a supporting frame in-
cluding forward and rearward bolsters each
having a longitudinally extending recess, a 85
bearing member slidable in each of said re-
cesses, an axle' mounted to swing upon each
end of each bolster,. a reach member mount-
ed to swing intermediate the ends upon said
frame and engaging in said bearing mem- 90
bers, connecting' means between said reach
member and said axles, and a draft tongue
mounted to'swing relative to said frame and
connected to said reach member, whereby
the axles are simultaneously cramped by the 95
lateral movements of the tongue.
2. In a vehicle of the class described, a
supporting frame, pivoted axles turning on
said frame and adapted to- carry bearing
wheels, a reach rigidly connected with said 100
frame, another reach movably supported on
said frame, connecting means between the
movable reach and the pivoted axles, and
roller bearing members. 31 and 32 arranged
side by side and operating to vibrate the 105
movable' reach and simultaneously cramp
the wheels, and a draft tongue pivotally
connected with both said bearing members,
as shown and described.
3. In a vehicle of the class described, a 110
supporting frame, pivoted axles turning
upon said frame and adapted to. carry bear-
ing wheels, a stationary reach supported
upon said frame, a movable reach supported
upon said frame, said reaches having bear- 115
ings at their forward ends, connecting
means between said movable reach and said
pivoted axles, a half roller member connect-
ed to said stationary reach and sidabk
through the bearing of the movable' reach, 120
another half roller member connected to the
movable. reach and slidable' through the
bearing of the stationary reach, and' a draft
tongue pivotally connected to both' of said
roller members and operating to vibrate the, 125
movable reach and effect the simultaneous
cramping of said wheels.
4. In a vehicle of the class described, a
forward bolster and a rearward bolster, piv-
oted' axles swingingly connected respectively 1302
