of the Commissioners of Patents on the 17th December 1881.

TIP-VANS OR WAGGONS."
"IMPROVEMENTS IN
My Invention relates to improvements in tilting vans or waggons for conveying
and discharging street slops, dust and other refuse, stones, gravel and other earthy
matters in bulk and it has for its object to simplify the construction of such vans
and lessen their cost.
In carrying out my Invention the under frame or bed upon which the body of
the van is supported is shortened so as not to extend in rear of the hind wheel axle
whilst the body overhangs the axle to the usual extent, and the side bars of the
bed frame instead of being straight are cranked or bent outwards beyond the width
of the van body at a point in their length in such manner as to admit of the body
passing between them when in the tilted or inclined position, the body being
arranged to turn upon hinges or joints situated at or near the cranked part of the
side frames. When in the horizontal or raised position the body rests upon the
fore part of the bed frame in advance of the joints the frame being supported upon
a swivelling fore carriage as usual. The rear part of the bed frame is supported
upon the hind wheel axle by springs in the form of one half of a semi elliptical
spring attached to the bed frame in front of the pivots, the rear ends of the bed
frame being also provided with indiarubber cushions which come upon the hind
wheel axle when the van is heavily loaded and travelling upon a rough road.

TIP VANS OR WAGGONS."
My Invention relates to improvements in tilting vans or waggons for conveying
and discharging street slops dust and other refuse, stones, gravel, and other earthy
matters in bulk and it has for its object to simplify the construction of such vans
and lessen their cost.
In carrying out my Invention, the under frame or bed upon which the body of
the van is supported is shortened so as not to extend in rear of the hind wheel
axle whilst the body overhangs the axle to the usual extent, and the side bars of
the bed frame instead of being straight are cranked or bent outwards beyond the
width of the van body at a point in their length in such manner as to admit of
the body passing-between-them-when.in.the tilted or inclined position, the body
being arranged to turn upon hinges or joints situated at or near the cranked.
part of the side frames. When in the horizontal or raised position the body
rests only upon the fore part of the bed frame in advance of the joints. The bed
frame is supported at the front end upon a swivelling fore carriage as usual and at
the rear part upon the bind wheel axle by means of springs attached to the bed
frame near the pivots, indiarubber cushions being also provided for the rear ends
of the bed frame to rest on when the van is heavily loaded and travelling upon a
rough road
The Drawing shows a perspective view of my improved tilting van or waggon,
the body being represented in the tilted position for discharging the contents.
A A¹ is the under frame or bed, B the body, C the fore carriage, D the hind
wheel axle, E the hind wheel springs, F the elastic cushions fixed on the clips of
the hind wheel axle. G is a latch rod pivoted to the front part of the body which
engages with the catches a on the bed frame to lock the body in the horizontal
position. The bed frame A is of the form shown, its side bars being carried outwards
at a so that whilst the fore part of said frame is of the same width as the body B
in order to support it when horizontal the rear portion is as much wider as is
necessary to permit of the body tilting between the side bars A' as represented in
the Drawing. The body is hinged at a point towards the middle of its length by
hinges b to the side bars of the frame A, the hinges being situated at the rear end
of this narrower portion of the frame as shown. The side bars extend rearwards
only as far as the axle D but the body extends the usual distance in rear thereof,
this axle D being cranked to permit of the tilting of the body.
Having described the nature of the said Invention of "Improvements in Tip
Vans or Waggons," and the manner of performing the same, I declare that what I
claim as the Invention to be protected by the hereinbefore in part recited Letters
Patent is
1st. A tipping van or waggon, in which the body tips or works on hinges fixed
directly beneath to its underside and to a main or bed frame as shown and described
for the purpose specified.
2nd. A tipping van or waggon in which the main or bed frame is constructed as
described and in which the body pivoted thereon rests by its fore part only upon

page_text: the fore part of the frame and in tilting works between the rear extensions thereof
substantially as shown and described.
3rd. In a tilting van or waggon the main frame of the form described and the
body pivoted thereon the cranked hind wheel axle, springs, and cushions combined
and arranged substantially as shown and described.
In witness whereof I the said William Bowen have hereunto set my hand
and seal this Sixteenth day of June A.D. 1882.
