tive ends pivotally connected thereto, by
means of the king pins 30 and 31, respec-
tively, in the well known manner.
For the purpose of connecting the front'
5 trailer to the truck, I have provided the link
32, whose rear end is pivoted between .the
forward ends of the side members 10' 10',
which form the bearing 10. Secured to the
front ends of these side members are the
10 arcuate plates 33, 33, which are spaced
apart, forming the bearing through which
the link 32 extends, said bearing permitting
the vertical movement of the link but hold-
ing it firmly against lateral movement. The
15 upper and the lower ends of the plates are
secured together by means of the bolts 34,
34, which pass through the respective pipe
sections 35, 35, interposed between said
plates and against the ends of which the re-
20 spective plates rest. The forward end of
the link 32 has the bearing members 36, 36,
secured thereto, and arranged in alinement,
one in front of the other. The numeral 37
designates the circular bearing plate' to .the
25 upper side of which a strap is secured whose
ends are formed into spindles 38, 38, which
operate in their respective bearings 36, 36.
The rear end of the trailer body 1, carries
the bearings 39, 39, which are spaced apart,
30 and in transverse alinement, and a bearing
plate 40 is provided upon which the bear-
ing plate 37 rests, said last mentioned plate
having the strap 41 secured thereto, whose
ends terminate in spindles 42, 42, which
35 operate in the bearings 39. The bearing
plates 37 and -40 have alined central bear-
ings to receive the bearing pin 43, upon
which said bearing plates operate, thus
forming a universal connection between the
40 truck and the trailer attached thereto, form-
ing a flexible connection necessary in pass-
ing over rough and uneven road surface,
thus imparting great flexibility to the ve-
hicle.
45 In Figs. 5 and 6, I have shown a single
trailer connected' to the truck. When a' sin-
gle trailer is used, the coupling' pole 8' is
extended forwardly and the bearings 36, 36,
are secured to the forward end thereof. The
50 forward end of the chains 25, 25, in this
form, are connected to the staples 26' 26',
which are secured to the truck body; and the
rear ends of these chains are connected to
the double-tree 23, as herein described, said
55 double-tree being pivotally connected to and
supported by the bearing 44, which is car-
ried by' the front end of the trailer body,
and through which the coupling pole 8' ex-
tends. In going around corners, or in turn-
60 ing around, as illustrated in Fig. 1,-'the
flexible' connection uniting the - coupling
poles 8 and 9 yields, 'the pole 9 sliding
through its bearing 11. The draft chains25, 25, serve to connect the trailers together,
and sustain the pull, while the coupling poles 65
being rigid in themselves, serve to guide
the trailers and hold them in their proper
relative position in making turns, and the
connection of the draft chains to the pivot-
ally mounted double-tree permits said dou- 70
ble-tree and chains to accommodate them-
selves to the different positions of the trail-
ers in following crooked roads, going around
curves and in turning around.
What I claim is: 75
1. A vehicle including, front and rear
wheels, frames mounted thereon, coupling
poles attached to the frames, one of which
is fixed, and the other of which is slidable
through a bearing in its frame, the adjoin- 80
ing ends of said coupling poles being flex-
ibly connected together, 'a double tree pro-
vided with oblong end bearings, pivoted to
one of said frames, draft chains connected
at one end to the other frame, and whose 85
other ends are adjustably connected to said
bearings.
' 2. A vehicle including front and rear
wheels, frames supported thereby, coupling
poles connected to the frames and flexibly 90
connected together, a double-tree having ob-
long end; bearings pivoted to one frame,
devises carried by the double-tree and mov-
able in said bearings lengthwise relative to
the double-tree, chains connected at one end 95
to said devises and at their other ends fas-
tened to the other frame.
3. A vehicle including a 'truck, a trailer
connected thereto, by means of a universal
coupling, a double-tree pivoted to: the trailer 100
and having. oblong end. bearings, draft
chains fastened at one end to the truck body,
and means movable lengthwise relative to
the double-tree in said bearings, to which
the other ends of the chain are'attached. 105
4. A vehicle inchiding a truck, a pair of
trailers connected thereto, a flexible: connec-
tion by means of which the front trailer is
attached to the truck, coupling poles car-
ried 'by the trailer-frames and flexibly con- 110
nected together, one of said coupling poles
being secured in its frame and the other
being slidably mounted in its frame. a
double-tree' pivotally secured to the last
mentioned 'frame, draft chains attached at 115
one end to said double-tree by means which
are movable lengthwise, relative thereto, and
the other ends of said chains being secured
to the other frame.
In testimony whereof I have signed my 120
name to this specification in' the presence of
two subscribing witnesses.
