page_text: I, WALTER LYMAN FRENCHI, Merchant of No. 134 North Main Street, Brockton,
Plymouth County, Massachusetts, ono of the United States of America, do hereby
declare the nature of this invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:—
Figure 1 is a side elevation of a dumping wagon, constructed in accordance with
my invention, with its body in a horizontal position upon its truck.
Figure 2 a vertical section representing the body in its inclined or dumping
position.
Figure 3 a plan of the wagon truck detached.
Figure 4 a transverse section on the line of Fig. 3.
Figure 5 a transverse section on the line y y of Fig. 3.
Figure 6 a sectional detail representing one of the guide rods and the guide roll
under which it travels, and which is not revealed to view in Fig. 2.
Figure 7 the device for locking the body when seated upon its truck.
The aim of my invention is to 80 construct a wagon (or four wheel vehicle) that
its body may be readily transposed from its ordinary horizontal or loading position,
to one inclined to the truck, in order that the load may be instantly discharged
by gravity, instead of removing it by successive operations, and this invention con-
sists in a wagon body made separate from and adapted to slide upon its truck
and to be tipped at an angle thereto, and be returned to its original horizontal
position by means of the construction hereinafter to be described and claimed.
In the said drawings A represents a wagon truck, and B B B B its four wheels.
This truck consists of a series of parallel longitudinal stringers a a a a Fig. 3
equidistant from each other, and secured at their ends by transverse cross bars bb
supported in the usual way on the axles c c. Located in apertures cut through
the stringers, and turning freely on axle rods or pins, are a series of friction
rolls d dete, the upper portion of each projecting above the horizontal plane of
the stringers; the rolls d¹ etc. at the rear of each also projecting beyond its
stringer (see Figs. 2 and 3) which is cut away to admit of the same. These end
rolls d d etc, revolve upon a common axial rode which extends transversely
from side to side of the truck. Beside these end rolls d d are two guide rolls h h
also turning freely on the rode and located near the insides of the outer stringers
and near the forward end of the truck are two transverse rods to be further
referred to. C is a wagon body of a length exceeding that of the truck so that
when seated on the friction rolls of the latter, it will project beyond the rear of
the truck (see Fig. 1). At the rear of the body and extending down from the
inside of each of its outer longitudinal sills is a hent rod 7 of the form seen in
Figs. 2 and 6, its longer portion 12 being parallel to the length of the sill, and its
two ends 13, 14 bent at right angles thereto.
This rod serves as a guide, and when the body is seated on the truck or tilted
down at its rear. and during its movements from one position to another, the path
of this guide rod lies in the vertical plane passing through the groove in the guide
roll h, thus insuring the proper alignment of the wagon body at all times (Figs. 1

and 6). When the wagon body is tilted down to the rear, into the position for its
load to slide out by gravity, the bottom m (Fig. 2) rests upon the ground, being
limited in its angular descent by the bent portion 13 of the guide rod.
wedge-shape hooks secured respectively to the insides of their outer contiguous
sills near their forward ends. When the body is in a horizontal position,
and is slid forward on its seat, these hooks catch under the transverse rods ii and
draw the body snugly down thereon; and to retain it in this, its loading position,
I employ a vertical sliding bolt p mounted in a casing secured to the outside of
cue of the stanchions of the body C, the lower end of the bolt entering a staple
secured to the outside of the truck A beneath.
When the body is to be slid backward, the bolt is raised by its knob, until its
lower end is liberated from the staple, and given a partial revolution, when the
knob enters a recess in the casing and supports the bolt in its unlocked position,
the body being then free to be pushed to the rear.
"f
The number of the sills of the body correspond to those of the stringers
of the truck, and to reduce friction and wear on the rolls, the underside of each
sill is sheathed with metal (Figs. 1, 4 and 5). The advantage of a dumping wagon
over an ordinary two-wheel tip-cart is the capacity of the wagon for carrying
greater loads. From the foregoing it will be seen that for general use, for instance
in farm work or carrying earth, stones etc., employed in the formation of roads etc.,
a dumping wagon constructed in accordance with my invention is a valuable aid
in facilitating the progress of the work.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
1 claim is―
1st. As an Improvement in Dumping wagons. A truck A having a series of
friction rolls d and a series of friction rolls dd, all of which project above
its upper surface, the rolls also projecting beyond the rear of the truck,
in combination with a body C, a means of alignment for the latter during its
movements forward and back on the truck and while being tipped away from
and returned to its seat thereon, and means for holding and locking the body
in its horizontal or loading position, constructed to operate as described.
2nd. In combination, a wagon truck A with its friction rolls d d, d d and
guide rolls located on a common axis e, a wagon body C having projecting
from its underside guide rods which act in conjunction with the guide rolls h h
to preserve the alignment with the truck of the body in all its movements, and
devices for holding and locking the body forward in its horizontal or loading
position, substantially as set forth.
3rd. The truck with its friction rolls dd, d d and guide rolls hand with
transverse rods ii near its forward end, in combination with the body having guide
rods and with hooks to engage with the rods ii, and a bolt p for locking
the body in its horizontal position, as specified.
4th. The truck with its longitudinal stringers a, the friction rolls d, d, the guide
rollsh, their axial rod e ant the rods ii, in combination with the body having
longitudinal sills, corresponding in number to that of the stringers, and sheathed
with metal on their undersides, guide rods 17, a pair of wedge-shape hooks n n
and a vertical bolt 7 for keeping the body in its loading position, as described.
Dated this 14th day of August. 1897 at Brockton, Mass.
