PROVISIONAL SPECIFICATION.
Improvements relating to Barrels or Drums for Winches or similar
Machines.
We ROBERT WELFORD of Hunters Hall Sunderland Engineer and PERRY
MITCHINSON of Percival Street Sunderland Engineer do hereby declare the nature
of this invention to be as follows:
These improvements have for their object the easy alteration or increasing and
decreasing of the size of a barrel or drum so as to make it effective for doing
light or heavy work. The main feature consists in providing a number of longi-
tudinal pieces (upon which the rope or chain winds) which are secured to or in the
side flanges at the required diameters by adjustable rings or segments or screws or
other means.

Improvements relating to Barrels or Drums for Winches or similar
Machines.
We ROBERT WELFORD of Hunters Hall Sunderland Engineer and PERRY
MITCHINSON of Percival Street Sunderland Engineer 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 :-
These improvements have for their object the easy alteration or increasing and
decreasing of the size of a barrel or drum so as to make it effective for doing light
or heavy work. The main feature consists in providing a number of longitudinal
pieces (upon which the rope or chain winds) which are secured to or in the side
Hanges at the required diameters by adjustable rings or segments or screws or
other means.
In order that these improvements may be better understood we give a description
with drawings of a winch or crane barrel showing how our improvements may be
carried out.
Fig. 1. is a longitudinal elevation partly in section of a barrel. Fig. 2. is an end
view of the same partly in section.
A is a shaft. B. are side flanges C. bars in position for a small size and heavy
lifts aud C' for a large size and light litts. D are segments for fixing bars in
position and E is a screw for actuating said segments. The number of segments
and screws used will be regulated according to practical requirements. It will be
understood that by actuating the screws and withdrawing the segments from the
bars these are left free to be moved from one position to another and that when
the bars are all either at one diameter or another the screwing back of the segments
against the bars fixes them firmly. It can be seen that these or other bars could

other suitable side flanges used and we desire it to be understood our invention
is not confined to the mode of construction shown in the drawing but
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 :-
1st. Using bars or pieces to easily alter (or make up) winding barrels for
different diameters.
2nd. Arranging bars lengthwise, with side flanges (or discs) in which wedge
segments are used to fix said bars at a diameter suitable for the work to be done.
