Improvements in Cork Pullers.
I, PHILIP ARTHUR NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, 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:-
The invention relates to a cork puller, and is directed to a structure and arrange-
ment of parts which will enable the operator to press the bottle at a convenient
angle into the mouth of the cork puller, while the hand not engaged with the
bottle, may work the operating lever to advantage; a gravity catch, for use in
connection with the cork stripping device, being so arranged that it may be kept
free from foreign substance which might have a tendency to clog it and prevent
it from promptly operating.
In the accompanying drawings,
Fig. 1 represents the cork puller, in side elevation, attached to the edge of a
suitable support, with the bottle in position to have its cork pulled;
Fig. 2 is a similar view with the bottle removed, and the cork on the puller in
position to be stripped by the return movement of the handle; and
Fig. 3 is a similar view, showing the casing partially broken away, to disclose
the operating parts within it.
A represents the barrel or casing in which the operating plunger B reciprocates
by means of power applied thereto, through the operating lever C. The barrel
or casing A is preferably formed integral with the fixed jaw a of the clamp, the
movable jaw of the clamp consisting of a disc D swivelled on the end of a set
screw d, having a screw-threaded engagement with an arm a¹ of the casing,
The barrel or casing A is set
integral with the barrel or casing A and jaw a.
obliquely to the plane of the support E, to which the puller is clamped for use,
so that in pressing the bottle F into engagement with the mouth of the casing,
the pressure will be directed advantageously, so far as the operator is concerned,
and also advantageously so far as the support of the puller is concerned, that is,
partially toward the support E. The operating lever C has a slot and pin engage-
ment, with a pair of lugs a² uprising from the jaw a, and preferably having a
slant corresponding to that of the barrel or casing A.
9.
The plunger has swivelled to its end, within the casing, a worm screw G, for
piercing the cork of the bottle, the said worm screw G being caused to rotate
as the plunger is moved within the barrel or casing A, by means of a nut 9 having
a sliding engagement with the interior of the barrel or casing A, and provided
with a winding perforation corresponding to the wind of the worm screw G.
The nut is provided with a pin g' extending laterally therefrom through an

page_text: elongated opening a³ in the wall of the casing, which prevents the nut from
turning within the casing, so that as the worm is forced through the nut, the
worm will have a rotary motion imparted to it.
The nut is held at the proper time against a sliding movement within the
barrel or casing, by means of a gravity latch H, pivoted at h to the exterior of
the casing A, and provided with a weighted end h¹, which, at the same time,
forms a part of the mouth of the casing, and rests normally in the path of the
nozzle of the bottle; so that when the nozzle of the bottle is forced into the mouth
of the casing, it will engage the weighted end of the gravity latch, and rock
it in a direction to release it from the stud g¹ on the nut, permitting the latter
to slide upwardly within the casing as the plunger is withdrawn.
The operation is a follows:-
The nozzle of the bottle having been pushed into the mouth of the casing, and,
by its engagement with the end of the gravity latch, having swung the said
latch out of engagement with the stud g¹ on the nut, the lever-C is pulled down-
wardly, thereby driving the plunger downwardly within the barrel, and hence
causing the worm G to enter the cork, the said worm being rotated by its engage-
ment with the nut g. The return movement of the lever C will draw the cork
from the nozzle of the bottle, the nut g travelling freely along within the casing,
because of the latch H being still held out of engagement with it. The bottle
being then removed the downward stroke of the lever C will bring the stud g¹ on
the nut into engagement with the hook of the latch H; and the latter, being free
now to act under the influence of gravity, will retain the nut in position, while
the return movement of the lever will strip the cork from the worm, and permit
it to fall out of the way, leaving the puller ready for another operation.¨¨
The location of the latch H where it can be readily freed from any foreign
substance which might tend to clog it, is a matter of advantage, while the latch
at the same time serving as a gravity latch, and forming a part of the mouth of
the casing, ensures the perfect action of the latch, there being no spring, as in
the case of spring-actuated latches, to weaken or break, and no possibility of the
nozzle of the bottle slipping past it, and hence releasing the nut.
The handle of the operating lever is well up away from the barrel or casing A.
where the weight of the operator can be utilized to advantage in applying power to
the plunger, making the instrument, as a whole, very effective.
.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed (as communicated to
me from abroad), I declare that what I claim is:
-
The cork puller with its casing, plunger, worm nut, gravity catch, and operating
lever, arranged and operating substantially as set forth.
