Improvements in Dumping Waggons.
We, MILLARD FILLMORE BLAKE, Stone Mason, HARRY SHRINER BROWN, Furniture
Dealer, and ABRAHAM LINCOLN MENTZER, Butcher, all of Martinsburg, County of
Blair, State of Pennsylvania,. U.S.A., 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 :—
This invention relates to a dumping waggon having a bottom divided transversely
into two. parts each of which is pivotted to the waggon frame and is adapted to be
separately tilted.
In the accompanying drawing. Fig. 1 is a top view of the body of a dumping waggon
constructed in accordance with this invention. Fig. 2 a side view of the same with
one of the bottom sections tilte. Fig. 3 a longitudinal section on line 3—3 of Fig.1.
Fig. 4 an underneath view.
The waggon frame consists of two side beams A a central beam A¹, two end cross
beams A and the usual bolsters A³. The waggon body consists of side and end pieces
is mounted upon the side beams 'A and is provided with the ordinary stakes a, for
taking into the collars a attached to the side beams. B are the two tilting sections
forming the waggon floor, each section being supported upon a transverse bar b which
bears at its ends in the longitudinal side beams A and passes through the central
longitudinal beam A' the bottom sections B having castings or eyes 6 attached thereto
and in engagement with the transverse rods or bars to support said sections in swinging
engagement with their supports. The bottom sections B are each made up of four
logitudinal beams B₁ to which the floor boards are secured, said longitudinal beans
being provided at their inner ends with depending portions and the rear ends of
the sections have upright pieces or boards 63 and b' which prevent the coal or other
material carried by the waggon from falling beyond said sections when they are being
dumped or tilted.
Care hangers, which are secured to the longitudinal side beams A on the outer
sides thereof, said hangers being constructed to present a horizontal rack bar on each
side of the waggon the teeth of the rack bars projecting upwardly. In mesh with these
rack bars are pinions & at the ends of two transverse shafts D which extend across the
waggon and are adapted to be moved in and out of engagement with the depending
portions b² of the bottom sections B each transverse shaft being provided with a hand
wheel which is turned to move said shafts sidewise, such movement being caused
by the pinions d engaging the teeth of the rack bars. It will be noted that by
providing the pinions and rack bars the transverse shafts D are inoved sidewise their
full length by simply turning the hand wheel at one end, and that when the said shafts
are moved to engage the under side of the depending portions 6 of the bottom
sections said sections will be positively retained in their normal horizontal position.
When the shafts D are moved out of engagement with the bottom sections or beneath
the transverse board A' the weight of the material will tilt said botttom sections and
will be dumped or deposited beneath the centre of the waggon.

page_text: In order to provide for returning the bottom sections to a horizontal position, at
each end of the waggon is mounted a transverse shaft E having a hand wheel for
operating the same, and these shafts are connected to the rear ends of the bottom
sections by chains or flexible connections e. By this arrangement the turning of
the shafts will bring the bottom sections to u horizontal position, and in order
to retain them in this position to permit the operator to manipulate the transverse
shafts D, the shafts E are provided with ordinary pawls and ratchets, as shewn.
It will be noted that the inner ends of the bottom sections B are recessed
centrally, so that their tilting movement will not be interfered with by the central
longitudinal beam A¹ and in order to provide an unbroken floor for the waggon
when the sections B are in a horizontal position the beam A' is built up on each side
of the transverse hoard A' by pieces A the ends of which are bevelled, as shewn, to
allow a tilting movement of the sections B, said movement being limited by the
engagement of the sections with the longitudinal beam, A'.
From the above, the operation of the dumping waggon will be readily understood,
and it will be noted that the stationary parts A and A" of the floor or bottom of the
waggon add materially to the safety of the waggon thus constructed, for should a
person be upon the waggon when the sections B of the bottom are released ample
standing space will be presented by said parts. These parts are also useful in
providing a stand for the attendant, from which he can remove material that will, be
likely to clog or impede the operation of the tilting bottom sections.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
:
1. In a dumping waggon provided with tilting bottom sections, of hangers on each
side of the waggon presenting horizontal rack bars; transverse shafts D having pinions
at their ends which engage or mesh with the rack bars, whereby said shafts can be
moved under the inner ends of the bottom sections by turning said shaft at one end,
substantially as described and shewn.
2. In a dumping waggon, the coinbination with the frame made up of longitudinal
side beams A, central longitudinal beam A¹, end cross beams A2 and bolsters A³, the
beam A being built up centrally and the frame having a central cross piece, of
transverse rods or bars bearing in the beams A and A¹, bottom sections B supported
upon said rods or bars and cut away centrally at their inner ends, together with
transverse shafts D having pinions, hangers attached to the waggon frame and
presenting rack teeth with which said pinions mesh, and transverse shaft E connected
to the rear ends of the bottom sections by chains or flexible connections, substantially
as described and shewn.
