Application fled September 11, 1916. Serial No. 119,571.
To all whom it may concern:
Be it known that I, CICERO H. LA CROIX,
a citizen of the U11'ted States, residing at
Bannister, in the county of San Augustine
5 and State of Texas, have invented a new
and useful Wagon, of- which the following
is a specification.
The object of the invention-is to provide
a vehicle of a convertible type consisting of
10 a plurality of members or elements which
when used together can be employed in the
transportation of long logs or timbers, and
which when not required for this purpose
can be disconnected and used independently
15 as trucks for hauling other objects or shorter
logs, and which when used together may be
caused to "track," the log supporting means
being so constructed and mounted as to
avoid cramping or twisting, and prevent un-
20 due strains upon the parts of the vehicle.
Further objects and advantages of the in-
vention wil-l appear in the course of the
following description, it being understood
that changes in the form, preparation, and
25 details of construction may be resorted to
within the scope of the appended claim,
without departing from the spirit of the in-
vention.
In the drawings Figure 1 is a side view
30 of a convertible vehicle constructed in ac-
cordance with the invention. Fig. 2 is a
plan view of the same showing the elements
in the positions which they assume in round-
ing a curve or turning a corner. Fig. 3 is a
35 rear view of one of the trucks. Fig. 4 is a
detail sectional view to show the mounting
of the bunks. Fig. 5 is a detail view in per-
spective of the coupling forming the con-
.nection joint.
40 The convertible vehicle embodying the in-
vention consists essentially of a onward
truck 10 and a rearward truck 11 respec-
tively having fixed or rigid rear axles 12
and 13 and pivotal front axles 14 and 15,
45 with a jointed connection 16 between said.
trucks consisting of members 17 and 18, of
. substantially equal lengths measured from
the vertical planes of the rear axle of the
front truck and the front axle of the rear
50 truck and being pivbta'ly united at 19,
whereby in rounding a curve or turning a
corner the forward end of the rear truck
is led through the connection in a direction
causing the wheels of the rear truck to track
55 those of the front truck.
In the construction illustrated the mem-ber 17 of the jointed connection is formed
as an extension-of the usual reach 20 of the
forward truck while the member 18 consists
of a short tongue mounted in the usual way 60
in the front hounds 21 of the rear truck.
The coupling between the members of the
connection should be of such construction
as to permit of the relative lateral swing-
ing movement of said members and at the 65.
same time permit a limited vertical relative
movement thereof, and to this end may con-
sist as shown of a clevis 22 on one of the
members carrying the removable pivot bolt
hereinbefore referred to as 19 and aneye 70
23 carried by the other member and tn-
gaged with said pivot bolt, the interval be-
tween the arms of the clevis being .such as
to permit the.indicated vertical movement
of one member relatively to the other to pro- 75
vide for differences in the level of the truck
wheels due to unevennesses of the surface of
the ground. The forward truck is provided
in connection with its front axle with the
usual hounds 24 and draft tongue 25. Also 80
mounted in the usual way in reference to
both trucks are the front rocking bolsters
26 and rear bolsters 27 and connecting the
front and rear bolsters and holding those
of each truck in relatively fixed positions 85
are tables 28 and 29, each preferably con-
prising a central or rest timber 30-31 and
side guide timber 32-33, to support the
forward and rear pivotal bunks 34-35.
These bunks may be of the ordinary and 90
well known construction having the termi-
nal chocks 36 and being removably pivoted
as at. 37 and 38 respectively upon said tables.
As illustrated in Fig. 2, and hereinbefore
mentioned, the turning of the forward truck 95
serves to lead the rearward truck outwardly
of the curve through the agency of the con-
nection between the trucks and at the same
time he bunks of the forward and rear
trucks are permitted to retain their paral- 100
elism heldby- the load consisting of long
timr'bers }or logs supported at. their ends re-
spectively by said bunks, so that the trucks
turn under the bunks and hence under the
load without disturbing the latter, and in 105
order to compensate for the relative shorten-
ing of the distance between the trucks in
making the turn, and which, if provision
were not made therefor would result in the
sliding of the lord or of one of the bunks 110
with reference to the load, the bunk of the
rearward truck has its pivot bolt 38 mount-
