page_text: LETTERS PATENT to Otto Julius Scholz, of No. 51, Sand Street,
Woolwich, in the County of Kent, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR PUTTING CAPSULES ON. TO BOTTLES AND OTHER
VESSELS."
Sealed the 10th November 1874, and dated the 29th May 1874.
PROVISIONAL SPECIFICATION left by the said Otto Julius Scholz
at the Office of the Commissioners of Patents, with his Petition,
on the 29th May 1874.
I, OTTO JULIUS SCHOLZ, of No. 51, Sand Street, Woolwich, in the
5 County of Kent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR PUTTING CAPSULES ON TO BOTTLES AND OTHER
VESSELS," to be as follows:-

page_text: Various machines for putting capsules on to bottles have before been
proposed, and ordinarily the capsule is compressed around the neck of
the bottle by a bag of elastic material acted upon by pressure.
By my improvements I am enabled to construct a machine by which
an equal pressure may be put upon all parts of the capsule with the
smallest possible amount of labor, and which is always in perfect
working order, whether used continually or at intervals only, which is
not the case in machines now employed. For this purpose I employ a
cylinder of thick vulcanized india-rubber acted upon externally by a
number of pushers, which by a compound lever action can be caused to
simultaneously move inwards towards the centre of the elastic cylinder
and so reduce its diameter, and if the head of a bottle with a capsule
upon it has been inserted into the interior of the clastic cylinder the
capsule will by it be pressed equally all around the head of the bottle.
The pushers at their ends are each received into slots in two plates fixed
at a short distance from each other, and which form the frame of the
apparatus. The slots radiate out from holes formed concentrically
through the two plates. At the back of each. pusher is an eccentric
surface or incline. Between the two plates is a ring which surrounds
the pushers, and which is fitted internally with other corresponding
eccentric surfaces or inclines. On the ring is a lever by which a partial
turn can be given to it either by hand or by a treadle, and when the
ring is thus turned the pushers are caused to move radially inwards and
compress the cylinder of elastic material which the pushers surround.
On the ring is also a balance weight to bring it back again to its normal
position whenever the treadle or lever handle is released.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Otto Julius Scholz in the Great Seal Patent Office
on the 28th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, OTTO
JULIUS SCHOLZ, of No. 51, Sand Street, Woolwich, in the County of
Kent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of May, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Otto Julius Scholz, Her special license
that I, the said Otto Julius Scholz, my executors, administrators, and
assigns, or such others as I, the said Otto Julius Scholz, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR PUTTING CAPSULES ON TO BOTTLES AND OTHER VESSELS," upon tho
condition (amongst others) that I, the said Otto Julius Scholz, my
cxccutors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Otto Julius Scholz, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and.
by the following statement thereof, that is to say :—

page_text: This Invention has for its object improvements in machinery for
putting capsules on to bottles and other vessels.
Various machines for putting capsules on to bottles have before been
proposed, and ordinarily the capsule is compressed around the neck of
the bottle by a bag of clastic material acted upon by pressure.
:
By my improvements I am enabled to construct a machine by which
an equal pressure may be put upon all parts of the capsule with the
smallest possible amount of labor, and which is always in perfect
working order. whether used continually or at intervals only, which is
not the case in machines now employed. For this purpose I employ a.
cylinder of thick vulcanised india-rubber acted upon externally by a
number of pushers, which by a compound lever action can be caused
to simultaneously move inwards towards the centre of the elastic cylinder
and so reduce its diameter; and if the head of a bottle with a capsule
upon it has been inserted into the interior of the clastic cylinder the
capsule will by it be pressed equally all around the head of the bottle.
The pushers at their ends are each received into slots in two plates fixed
at a short distance from each other, and which form the frame of the
apparatus. The slots radiate out from holes formed concentrically
througli the two plates. At the back of each pusher is an eccentric
surface or incline. Between the two plates is a ring which surrounds
the pushers, and which is fitted internally with other corresponding
eccentric surfaces or inclines. On the ring is a lever by which a partial
turn can be given to it either by hand or by a treadle, and when the
ring is thus turned the pushers are caused to move radially inwards and
compress the cylinder of elastic material which the pushers surround.
A counterbalance weight is also employed to bring the ring back again
to its normal position whenever the lever handle is released.
.
The machine is also constructed so that it may be worked either from
the front or back.
One end of the elastic cylinder may be closed by a disc of leather or
elastic material carried by a metal disc screwed to the other fixed plate
of the frame.
In order that my Invention may be fully understood and readily
carried into effect, I have shewn in the Drawings, hereunto annexed,
various views of a machine constructed according to my Invention.

page_text: Figure 1 shews a vertical section of the machine; Figure 2 is a trans-
verse vertical section; and Figure 3 a plan view of the same. In these
Figures a is the vulcanized india-rubber cylinder; b, b, are the pushers;
c, c, are the two plates fixed, as shewn, at a short distance from each
other, and also fixed to the bed d; c* is the circular hole formed in each
plate; and c' are the slots which radiate out from it, and in which the
ends of the pushers are received. The slots are shewn in the separate
view of a part of one of these plates at Figure 4. e is the ring which
surrounds the pushers; ei arc the eccentric surfaces with which it is
fitted, and which work against the eccentric surfaces b' at the back of
the pushers. The picces upon which the eccentric surfaces e¹ are formed
are held to the ring e by other rings e² screwed to it on either side, as
shown in the Drawings. f is the lever arm upon the ring; f¹ is a rod
passing to a treadle, and by which a partial turn may be given to the ring.
To this rod may be fixed a counterbalance weight, or if the eccentric
surfaces are so formed that the pushers are moved inwards by a down-
ward movement of the lever arm f, the counterbalance weight may be
carried by another arm projecting from the opposite side of the ring.
In place also of working the lever arm by a treadle it may, if desired,
be worked by hand. g is a disc of leather or other clastic material
closing one end of the clastic cylinder a, and held in place by a metal
disc, as shown. The opposite end of the cylinder a is retained by the
plate through which is a hole to allow the head of a bottle to be
inserted into the elastic cylinder.
When the machine is worked by a treadle it may be fixed upon a
bench in such a manner that the open end of the clastic cylinder faces
the person working the machine, or it may if preferred be placed
sideways.
The bottle whilst having a capsule pressed on to it may also be held
firmly and correctly in position by means of a lever acting against its
bottom end.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that I claim the com-

page_text: bined arrangement of machinery for putting capsules on to bottles and
other vessels, substantially as herein described.
In witness whereof, I, the said Otto Julius Scholz, have hereunto
set my hand and seal, this day of November, in the year of our
Lord One thousand eight hundred and seventy-four.
