OR IMPROVED MACHINERY OR APPARATUS FOR WITHDRAWING CORKS FROM BOTTLE NECKS
Year: 1885

page_text: I, FREDERICK THOMAS MARWOOD, of 39 King Street, Blackburn, County of
Lancaster, Cork Manufacturer, do hereby declare the nature of said invention for
NEW OR IMPROVED MACHINERY OR APPARATUS FOR WITHDRAWING CORKS FROM
BOTTLE NECKS to be as follows:-
"
This invention relates to a novel construction of machinery or apparatus for
withdrawing corks from bottle necks. In one form the machine is a vertical one
about two feet high and about six inches in breadth at the broadest part. The
arrangement is such that the corkscrew is positively driven into the cork. The
corkscrew is attached to the lower end of a vertical spindle working within the
central hole of a screw-threaded vertical spindle which is rotated by means of
bevel gearing and a handle. The corkscrew rotates with the screw-threaded
spindle in its downward traverse but does not rotate on its return or upward
movement until it meets a clutch device and is again put into gear with the
screw-threaded spindle-when the corkscrew again rotates and withdraws or
unscrews itself out of the cork which by this time has been drawn out of the
bottle neck and brought hard up against a shoulder which affords the friction
required to prevent it from turning round whilst the corkscrew is twisted out or
withdrawn from it.

COMPLETE
SPECIFICATION.
I, FREDERICK THOMAS MARWOOD, of 39 King Street, Blackburn, County of
Lancaster, Cork Manufacturer, do hereby declare the nature of my said invention
for NEW OR IMPROVED MACHINERY OR APPARATUS FOR WITHDRAWING CORKS
FROM BOTTLE NECKS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
"
This invention relates to a novel construction of machinery or apparatus for
withdrawing corks from bottle necks. In one form the machine is a vertical one
about two feet high and about six inches in breadth at the broadest part. The
arrangement is such that the corkscrew is positively driven into the cork. The
corkscrew is attached to the lower end of a vertical spindle working within the
central hole of a screw-threaded vertical spindle which is rotated by means of
bevel gearing and a handle. The corkscrew rotates with the screw-threaded
spindle in its downward traverse but does not rotate on its return or upward
movement until it meets a clutch device and is again put into gear with the
screw-threaded spindle-when the corkscrew again rotates and withdraws or
unscrews itself out of the cork which by this time has been drawn out of the
bottle neck and brought hard up against a shoulder which affords the friction
required to prevent it from turning round whilst the corkscrew is twisted out or
withdrawn from it.
The accompanying Drawings of which Fig. 1 is a front view; Fig 2 a sectional
elevation; and Fig. 3 a sectional side view shew the improved machine or
apparatus arranged vertically but it may conveniently be arranged to work at an
angle of any desired inclination.
A is a hollow standard to the top of which the apparatus may be attached.
B is a projecting forked arm-the forked part being arranged to receive the upper
end of the bottle neck and to prevent the bottle from being drawn upwards whilst
the cork is being withdrawn. C is an arm forming a stand (adjustable vertically)
upon which the bottle is placed. D is a metal casing or box forming the framing
of the apparatus and having a boss a constituting a bearing for the spindle b to
which are fastened at one end the handle c and at the other the bevel wheel d
gearing into the pinion wheel e through which passes the plain or unscrewed part
of the screw-threaded spindle f which is slotted to receive a key in the pinion e
(see Fig 6), the spindle f thereby rotating with the pinion e but being free to slide
up and down therein as hereinafter described. g is a vertical spindle working
within the screw-threaded spindle f carrying at its lower extremity the corkscrew h
and having attached to it immediately above the upper extremity of the screw-
threaded spindle f the ratchet wheel i (shewn in plan view at Fig 5). The pawl j
is pivotted upon the upper side of the disc k (forming the lower half of a clutch
device) having vertical projecting pins or arms l. 7 which enter holes in a second
disc m (forming the upper half of the clutch). The disc m is loose upon the
corkscrew spindle g but rotates therewith being provided with a key sliding in
a slot or key-way in the spindle g as shewn at Fig 4. A spiral spring n is

page_text: preferably employed to ensure the upper disc m descending with the lower disc k
as far as the stops o, o, upon the downward movement of the screw-threaded
spindle as shewn in dotted lines at Fig 3. p is an internally threaded bush
fastened to the lower end of the casing or box D by means of the fastening nut q
whose lower, edge forms a shoulder against which the cork r is drawn hard up as
herein before mentioned.
The action of the apparatus is as follows:
When the screw-threaded spindle f is rotated by means of the handle c and the
bevel gearing d. e, so as to cause its downward traverse the corkscrew h (whose
thread is of the same pitch as that of the screw-threaded spindle f) will, by means
of the ratchet and pawl arrangement i. j, be rotated and thereby caused to enter
and be positively driven into the cork as shewn in dotted lines at Fig 3.-The
handle c being then turned in the opposite direction the corkscrew will be pulled
upwards without rotating until the cork has been withdrawn from the bottle
neck and will not rotate until the lower disc or clutch k meets and is put into gear
with the upper rotating clutch m. whereupon the spindle g and the corkscrew h
will be again rotated-the continued upward movement of the corkscrew causing
the extracted cork to be brought hard up against the nut q which affords the
friction required to prevent it from turning round whilst the corkscrew withdraws
or unscrews itself out of the cork.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is
1. Arranging the corkscrew upon a spindle working within a screw-threaded
spindle in such manner as to be rotated therewith during its downward traverse
but so as not to be rotated during a portion of its return or upward movement
that is to say until the cork has been withdrawn from the bottle neck
substantially as described and shewn in the drawings.
•
2. The use or employment of bevel gearing, and a handle in combination with
a rotating spindle arranged and operating substantially as described and shewn in
the drawings for the purpose set forth.
3. The combination of parts constituting the improved machinery or apparatus
constructed, arranged, and operating substantially as described and shewn in the
drawings for the purpose set forth.
