PROVISIONAL SPECIFICATION.
Improvements in Metallic Wagons, Trucks, or Trams.
CHARLES WILLIAM LYON Engineer Thornhill-Lees near Dewsbury Yorkshire.
I do hereby declare the nature of this invention to be as follows:-
My invention has for its object an improved top hoop for metallic wagons and
the like, which can be attached & detached with less labour & at less cost than
heretofore.
The plates forming the sides & ends of the wagon body, are curled over a round
bar slightly larger than the round bars or bolts that form the top hoop. The top
hoop consists of four round bars or bolts passed through the curled side & end
plates & rivetted, screwed or bolted to angle plates or to each other where they
meet at the four top corners of the wagon in such a manner that the top hoop can
be put on & taken off without uncurling the side & end plates or damaging the
top hoop.
Dated this 4th day of March 1895.

COMPLETE SPECIFICATION.
Improvements in Metallio Wagons, Trucks, or Trams.
CHARLES WILLIAM LYON Engineer Thornhill-Lees near Dewsbury Yorkshire.
I 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:
My invention has for its object an improved top hoop for metallic wagons & the
like, which can be attached & detached with less labour & at less cost than
heretofore.
The plates forming the sides and ends of the wagon body are curled over a round
bar slightly larger than the round bar or bolts that form the top hoop. The top
hoop consists of four round bars or bolts passed through the curled side and end
plates & rivetted, screwed or bolted to angle plates or to each other, where they
meet at the four top corners of the wagon, in such a manner that the top hoop can
be put on and taken off again without uncurling the side & end plates.
Fig. 1 shews plan of top hoop bolted together, by the four bolts A. B. C. D. each
bolt having an angle head with a slot hole in it as shewn on drawing. In order to
take out the bolt A, the nut and washer must be taken off the bolt B and also off
the bolt A, then the bolt A can Le drawn out of the curled plate, as the bolt
head A having a slot hole in it, will pass over the projecting sorewed part of the
bolt B without taking out the bolt B.
In a similar manner the bolts B, C, and D can also be taken out & put back

page_text: The washer E fits against the head of the bolt A at F, so that when the top hoop
is fit up in position on a metallic wagon body, the screwed end of the bolt B cannot
move sideways.
In like manner angle plates may be put at the top corners of the wagon with
holes bored in them to receive the side and end bars forming the top hoop, these
bars may be ordinary bolts, or rivetted up at each end inside the angle plates.
Fig. 3 shews section through H. J.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is r
First. The use of four angle headed bolts with slot holes in them substantially as
herein described with reference to Fig. 1.
Second. The use of the washers E substantially as herein described with
reference to Fig. 1.
Third. The top hoop made in four parts and constructed that it can be put on
and taken off without uncurling the plates substantially as herein described.
