PROVISIONAL SPECIFICATION.
Improvements in or connected with Colliery and other
Waggons or Tubs.
I, WILLIAM Frederic Butler, of Highfield, Wrexham, in the County of
Denbigh, North Wales, Colliery Proprietor, do hereby declare the nature of this
invention to be as follows :-
This invention relates mainly to that class of colliery and other waggons or tubs
of which the bodies are made of comparatively thin iron or steel, and has for its
object, amongst other things, to provide for rendering this class of trucks or tubs
stronger, and better adapted to withstand the wear to which they are put, than
those now in common use.
In a metallic tub in which the bottom is rounded, or curved, and the beams or
bearers which support the body are made, say, of wood, I support or fix. such
beams or bearers to the tub body or truck by a strap at each end, such strap being
rivetted or bolted to the metal of the body and carried round outside the beans.
At the points where the beams pass the straps, such straps form, as it were, recesses
The beams themselves may be
or apertures through which said beams pass.
secured to these straps as well as to the bottom of the tub or truck, if desired.
The axles would, in this invention, be fixed to the beams or bearers in the usual
or any known way.
To give strength to the ends of this class of tubs or trucks, I carry the drawbar,
which is usually disposed at the bottom of the tub, vertically upwards at the ends,
and secure it by rivetting or bolting to the end plates. At the angle where the
drawbar serves to carry the couplings, it may be inade of greater than the normal
thickness.
The coupling links, that is those of the couplings which are directly connected
to the drawbar, are made somewhat of the shape of a horseshoe magnet, having a
withdrawable pin at the open end, on the end of which is a slight projection to
prevent it from being withdrawn from the upper arm of the link. The drawbar
is adapted to lie between the arms of the link and hold it in a horizontal position.
Near the bend of the link a stud is provided and adapted to serve as a strut. By
this construction the couplings are prevented from dragging on the ground and
coming into contact with the sleepers and other obstructions.

COMPLETE SPECIFICATION.
Improvements in or connected with Colliery and other
Waggons or Tubs.
I, WILLIAM FREDERIC BUTLER, of Highfield, Wrexham, in the County of
Denbigh, North Wales, Civil Engineer and Colliery Proprietor, 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 mainly to that class of colliery and other waggons or tubs
of which the bodies are made of comparatively thin iron or steel, and has for its

page_text: object, amongst other things, to provide for rendering this class of trucks or tubs
stronger, and better adapted to withstand the wear to which they are put, than
those now in common use.
In a metallic tub in which the bottom is rounded, or curved, and the beams or
bearers which support the body are made, say, of wood, support or fix beams or
bearers to the tub body or truck by a strap at each end, such strap being rivetted
or bolied to the metal of the body and carried round outside the beams. At the
portion where the beams pass the straps, such straps form, as it were, recesses or
apertures through which said beams pass. The beans themselves may be secured
to these straps as well as to the bottom of the tub or truck, if desired.
The axles would, in this invention, be fixed to the beams or bearers in the usual
or any known way.
To give strength to the ends of this class of tubs or trucks, I carry the drawbar,
which is usually disposed at the bottom of the tub vertically upwards at the ends
and secure it by bending it over the top of the tub and riveting or bolting to the
end plates. At the angle where the drawbar serves to carry the couplings, it may
be made of greater than the normal thickness.
The coupling links, that is those of the couplings which are directly connected
to the drawbar, are made somewhat of the shape of a horseshoe magnet, having a
withdrawable pin at the open end on the end of which is a slight projection to
prevent it from being withdrawn from the upper arm of the link. The drawbar is
adapted to lie between the arms of the link and hold it in a horizontal position.
Near the bend of the link a stud is provided and adapted to serve as a strut. By
this construction the couplings are prevented from dragging on the ground and
coming into contact with the sleepers and other obstructions.
In the drawings which serve to illustrate this invention,
Figure 1 is a side elevation of the colliery or other tub provided with my
improvements; whilst
Figures 2 and 3 are respectively plan and end view.
Figure 4 is a detailed view shewing the coupling links above specified.
With reference to the drawings, a are beams of the tub or waggon; bis the body;
care the wheels; are the straps which secure the beams to the body; e is the
drawbar, one part of which lies longitudinally at the bottom of the tub or waggon,
whilst the other parts e¹ are carried vertically upwards at the ends of the tub, and
are secured thereto, the projecting part e² of said bars, where they come together
and are fastened, being extended forward as shown.
The coupling links, shewn more in detail in Figure 4, are designated f, and are
made in the form, as will be seen, of a horse-shoe magnet, the straight parts of
which are connected together and stayed by a strut rivet stud g or the like, between
which and the inner edge of the curved part of the link, one of the ordinary
links comes.
At the opposite end of the link there is provided a withdrawable
pin, having a slight projection upon its end to prevent it being entirely
withdrawn from the upper arm of the link f. The position the links f take when
coupled to the truck, that is the drawbar thereof, is shewn in Figure 1 that is, the
horizontal position. It will be easily seen the links ƒ can be very readily coupled
to a drawbar, or uncoupled therefrom.
The straps d, it will be seen, are bolted to the body of the tub or waggon by
bolts and nuts or rivets d¹ and pass round the beams a in the manner shewn. The
straps may also be secured to the body of the tub or waggon at the bottom, and
to the beams a. At the part where the beams a pass through the straps d, they
fill the aperture formed by the bending of the said straps, and support or touch
the bottom of the tub.
The portion e of the drawbar is bolted or rivetted to the bottom of the tub or
waggon, and the vertical part el is similarly attached to the end plate of the tub
or waggon, and its upper end is turned round over the edge of the waggon
as shewn.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a colliery or other waggon or tub of the kind herein referred to, bands or
straps & secured to the body b of said tub or waggon, and passing round or over
the beams or sole bars a; substantially as set forth with reference to and shewn
in the drawings, for the purposes specified.
2. In a colliery or other waggon or tub of the kind herein referred to, the
vertical bars e secured to the ends of the tubs or waggons b, and forming part
of or connected to the horizontal portion e of the drawbar; substantially as herein
set forth.
