COMPLETE SPECIFICATION.
Mechanism to Allow the Barrels of Watches to be Removed from
the Movements without Displacing the Top Plates or Dials.
We, ALBERT JOHN MORCOM, and TOM MORCOм, of Nanpean, St. Austell, in the

in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
Our invention relates to the mechanism to allow the barrel of Watches to be
removed from the movement without displacing the top plate or dial.
And in order that our Invention may be thoroughly understood, we now proceed
to describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Figure 1 represents the elevation of the back of the inside case A, screwed to
the plate C which receives the dial.
The plate B is taken off by removing the screws I, I, when the barrel Wheel D
is easily taken out of its position.
Figure 2 denotes the side view of figure 1.
Figure 3 is the elevation of the front plate C on which the dial is fixed with
the click K kept in position by the spring L, and the click wheel E held secure
by the bridge J.
Figure 4 represents the side view of the barrel wheel D and the two arbor squares F
and H.
Figure 5, denotes the front view of figure 4.
Figure 6, is a view of figure 1, with the plate B, and guide socket G removed, by
withdrawing the screws from I', I'
The barrel wheel D, and the arbor square F, is also moved away from the square
hole F1, in the boss J¹, of the click wheel E.
Figure 7, represents the click wheel with the boss J¹.
Figure 8, is a side view of figure 7.

page_text: The object of this invention is to allow the barrel D to be removed from the move-
ment without displacing the top plate C or dial, and it consists as follows:-
The pivot of the barrel arbor usually used and entering the bottom plate is entirely
dispensed with, and in its place a square F is formed which is fitted to an improved
click wheel E, with a boss J attached, which takes the place of the barrel arbor pivot
by coming through the plate, and. having a square hole F¹ in the centre admits the
before mentioned arbor square F, so that the barrel D can be lifted, and easily removed
from the movement without displacing the top plate C or dial. The barrel space in
the top plate being made sufficiently wide to allow the barrel to easily slide out when
released from the square hole F in the boss J¹ of the click wheel E, after the plate is
removed.
The click or ratchet wheel with boss attached is kept in position by a bridge J
securely fastened to the plate C.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
First The combination of the bottom arbor square of the barrel wheel F, to fit
into the square hole in the boss J¹, attached to the click wheel E, substantially as
