PROVISIONAL SPECIFICATION.
Improvements in Machinery. Guards or Protectors.
I GEORGE ROBSON 5 Gun Lane Limehouse West India Dock Road in the
County of Middlesex Engineer do hereby declare the nature of this invention to be
as follows:-
Guards or protectors for the safety and protection of workmen employed in
factories, mills, forges, engineers & boiler makers shops or wherever overhead
shafting is used, the sketch illustrates the method of constructing the protectors &
the manner in which they are fixed over the overhead shafting so that no rope,
chain, & most especially persons clothes can possibly get entangled while the
shafting is in motion.
Figs. 1 and 2 are sections or end views.
Fig. 3 is a side elevation.
B, B are wrot iron hangers about 14" diameter & about 2 or 3 feet long according
to circumstances, fixed with " or " bolts to a beam C about 6 or 8 inches wide &
about 3" thick supported by the beams or joists of the building. The protectors or
guards d to be made of sheet iron about " thick and carried a little below the under
side of the shaft circular or V form or if necessary could be made square, all
practical men know the danger that workmen are exposed to even in the case of a
belt coming off it has to be put on at great risk to the men whose business it is to
replace the belt on the pullies, e, it is not always they can avoid and prevent their
clothes getting entangled round the shaft, and the consequences being generally
fatal to them, whereas if due care is taken by fitting a protection over the shafting,
it is quite impossible for any harm to take place, the belt will simply lay motionless
so that the workman can put up a ladder and rest it against the guards he can then
rest his arms on the same and with full confidence perform the operation of replacing
the belt without any fear of being hurt.

material) and carried a little below the under side of the shaft, s, circular or
V form or if necessary could be made square.
All practical men know the danger that workmen are exposed to even in the case
of a belt coming off it has to be replaced at great risk to the men whose business it
is to do so it is not always they can avoid and prevent their clothes coming in contact
with the shaft and the consequences generally are fatal to them whereas if due care
is taken by fitting a protection over the shafting it is quite impossible for any harm
to take place the belt will simply lay motionless on the protector so that any person
can step up and do any thing that is required with perfect safety.
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,
1st. The construction of guards or protectors over overhead shafting as illustrated
in drawing (left with Provisional Specification) Figs. 1, 2, and 3.
2nd. The manner of constructing and method of securing the same in their places,
as illustrated in the drawing Figs. 1, 2 and 3.
