Improvements in Capsuling Machines.
I, JAMES DUNLOP MITCHELL of 136 Ingram Street, Glasgow, in the County of
Lanark, Glass Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention relates to that class of machines for securing capsules upon bottles
in which hydraulic or other pressure is applied to compress a cup of rubber or other
elastic substance whereinto is placed the neck of the bottle having on it the capsule,
and the present improvements have for object to dispenso. with the necessity for
operating the apparatus by hand or foot the capsuling operation being effected in the
act of placing the neck of the bottle within the cup.
The machine is composed of the usual cylinder or casing containing water or other
fluid and fitted with the capsuling cup but in lieu of having a movable plunger operated
by a hand or foot lever it is provided with a stationary plunger whilst the cylinder
or casing together with the cup is fitted to slide on the plunger a spring or like
device being provided to retain the casing normally in the position in which the bottle
nay freely be inserted within the capsuling cup.
In operation the bottle neck having on it a capsule is pushed by hand into the cup
with such force as to cause the cylinder to slide upon the plunger and create such a
pressure of the water or other fluid within the casing as will serve to close the cup upon
the capsule and press it tightly upon the bottle neck. On withdrawing, the bottle the
cylinder or casing is pressed back to its normal position of rest by the spring and.is
ready for a repetition of the capsuling operation.

Improvements in Capsuling Machines.
I, JAMES DUNLOP MITCHELL of 136 Ingram Street Glasgow, in the County of
Lanark, Glass Merchant, 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 relates to that class of machines for securing capsules upon bottles 5
in which hydraulic or other pressure is applied to compress a cup of rubber or other
elastic substance whereinto is placed the neck of the bottle having on it the capsule.
The present improvements have for their object to dispense with the necessity for
operating the apparatus by hand or foot the capsuling oporation being effected in the
act of placing the neck of the bottle within the cup.
Referring to the accompanying drawings fig. 1 of which is a sido elevation; fig. 2
a plan; fig. 3, a longitudinal section and fig. 4 an end elevation of my improved
capsuling machine, whilst fig. 5, is a cross section on the line X--X, fig. 2, the.
machine as constructed under this invention consists of the usual cylinder or casing a,
containing water or other fluid and which is or may be provided with a filling
screw, and an air escape tap m, and is also fitted with an india rubber or other elastic
capsuling cup b, but in lieu of being constructed with a movable plunger operated by
a hand or foot lever it is provided with a stationary plunger c, cast or otherwise secured
to the supporting bracket d, whilst the cylinder or casing a together with the cup b
is fitted to slide on the plunger e, tho sliding casing being packed fluid tight by
means of a cup leather e, fitted to the inside of the screw nut f. For the purpose of
retaining the casing normally in tlie position in which the bottle may freely be inserted
within the capsuling cup, a weight or weights g, suspended by cords g' from a cross
piece or bar working on guide rods i secured to the supporting brackets d, j, is
or are provided. Or instead of using weights, springs or equivalent devices may be
employed.
In operation the bottle neck having on it a capsule is pushed by hand into the
cup with such force as to cause the cylinder a, to slide upon the plunger c, and
create such a pressure of the water or other fluid within the casing and around the
cup as will serve to close the cup upon the capsule and press it tightly upon the
bottle neck. On withdrawing the bottle the cylinder or casing is drawn back to its
normal position of rest by the suspended weight or weights or equivalent device and is
ready for a repetition of the capsuling operation.
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 :-
1. In a capsuling machine, operated as hereinbefore described, the application and

page_text: 2. In a capsuling machine operated as hereinbefore described, a cylinder or casing
adapted to slide on a stationary plunger, substantially as described and shown on the
accompanying drawings.
3. In a capsuling machine, operated as hereinbefore described, the combination of
the cylinder or casing a, sliding on the stationary plunger c, with a weight or weights
suspended from a cross piece h for the purpose of retaining said cylinder in its normal
position.
4. The general arrangement and combination of parts of my improved capsuling
machine.
