page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for
the Invention of "AN IMPROVED PRESS FOR COMPRESSING SUBSTANCES
FOR PACKING IN THE FORM OF BALES, OR FOR OTHER PURPOSES." A com-
munication from abroad by John Jordan Eckel, of New York, in the
United States of America...
Sealed the 12th April 1861, and dated the 2nd November 1860.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 2nd November 1860.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "AN IMPROVED PRESS FOR COMPRESSING
SUBSTANCES FOR PACKING IN THE FORM OF BALES, OR FOR OTHER PURPOSES," to be
as follows:-
The object of this Invention is to obtain a press of simple and economical
construction which will admit, under the same application of power, of giving
two different degrees of pressure so that the substance may be compressed:
expeditiously and in a proper manner, an excess of power being dispensed;
with for speed when speed is required, and the latter dispensed with when
power is required.
:

page_text: The Invention consists in the employment or use of two different means or
arrangements of gearing for actuating the follower or plunger, such gearing
being so combined and arranged that either may be operated when necessary,
and the desired end attained. The plunger or follower is provided with two
rack bars which are actuated by gearing above, whereby the rack bars and
plunger are driven down quickly in the first instance, when speed rather than
power is required. This speed gearing is mounted on a cross head, which is
connected by means of side rods to a system of gearing at the lower part of
the press, and by means of this second arrangement of gearing a powerful
pressure may be applied to the plunger after it has been brought down by the
speed gearing. Each of these arrangements of gearing is provided with
separate means for actuating them, so that either may be used according to
the circumstances of the case.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office 1
on the 2nd May, 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 'I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.

William Edward Newton, Her special license that I, the said William
Edward Newton, my executors, administrators, and assigns, or such others 2
as I, the said William Edward Newton, 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 s
Invention for "AN IMPROVED PRESS. FOR COMPRESSING SUBSTANCES FOR PACKING
IN THE FORM OF BALES, OR FOR: OTHER PURPOSES," being a communication from
abroad, upon the condition (amongst others) that I, the said William Edward'
Newton, by an instrument in writing under my hand and seal, should'
particularly describe and ascertain the nature of the said Invention, and in. 3.

page_text: 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I; the said William Edward Newton, 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, reference being had to the Drawings hereunto annexed;.
and to the letters and figures marked thereon (that is to say):-
The object of this: Invention of "An Improved' Press. for Compressing
Substances for Packing in the Form of Bales, or for other Purposes," is.to
obtain a press of simple and economical construction which will admit, under
the same application of power, of giving two different degrees of pressure so.
that the substance may be compressed expeditiously and in a proper manner,
an excess of power being dispensed with for speed when speed is required, and
speed may be dispensed with when power is required.
The Invention consists in the employment or use of two different means or
arrangements of gearing for actuating the follower or plunger,. such gearing
being, so combined and arranged that either of the arrangements may be
operated when necessary, and the desired end attained.
:
In the accompanying Drawings; Fig. 1 is an end elevation of a press con-
structed according to the present Invention; Fig. 2 is a side sectional view of
the same taken in the line x, a; of Fig. 1; Fig. 3. is a transverse section of
the press taken in the line y, y, of Fig. 2; and Fig. 4 is. a plan or top view.
Similar letters of reference indicate corresponding parts in the several
Figures.
1.
A represents an upright framing, the principal part of which is enclosed. to.
form a press box B, in which the substance to be compressed is placed: The
box B is provided with a door C at each end; D is a follower or, plunger,
which is placed within the box B, and is allowed to rise and fall freely therein.
This follower or plunger has two vertical rack bars E, E, attached to it; these
bars being each provided with three racks a, a, b, the racks b being at the
inner sides of the bars, and the racks a, a, at the two adjoining sides, as seen
in Fig. 3.
The rack bars E, E, pass through a cross head F, the ends of which are
fitted in slots at the upper parts of the framing A, and into the racks 6. of the
bars E pinions c gear. The pinions c are mounted on shafts d, d, which are
connected at one end by toothed wheels e, e. One of the shafts & has a spur
wheel G on it, and into this wheel gears; a pinion: f mounted on a driving.

page_text: shaft 9, which has a crank h..at one end of it. Behind each bar E there is
a friction roller i, against which the bar E bears, and is supported in a vertical
position.
The racks a, a, of the bars E, E, have pawls j, which catch into them, and
to each end of the follower or plunger D there is attached a pawl k, and these
pawls are in contact or engage with racks I, l, at the inner sides of the framing.
A, as shewn in Fig. 1.
From the above description, it will be seen, that by turning the shaft g the
follower or plunger D may be raised or lowered within the box B, and when
the follower or plunger is forced down, and the substance below it is com-
pressed, the racks a, l, and pawls j, k, prevent the follower or plunger: from
casually rising.
The above arrangement of gearing admits of a speedy movement of the
follower or plunger D, and it is used only at the first movement of the follower
or plunger. When additional power is required, the follower or plunger is
operated through the medium of the cross head F, the pawls j, j, being fitted
in the racks a. This cross head has an arm or bar G' attached to each end
of it. These arms or bars extend down at each side of the framing, and they
are fitted at their. lower ends on excentrics 'm, m, which are placed on the
ends of a shaft H that passes through the base I of the framing A. At the
ends of the shaft H there are secured spur wheels J, J; these wheels gear
into pinions n, n, which are placed on shafts o, o, the outer ends of which
have wheels p, p, on them, and these wheels gear into pinions 9, 9, on shafts
r, r, to which the power is applied.
When the follower or plunger D has been forced down sufficiently far by
the gearing connected to the cross head F, and previously described, the
shafts r, r, are rotated, and the shaft H is turned through the medium of the
gearing J, J, n, n, p, p, q, q, and the excentrics m, m, will draw down
the cross head F, and the follower or plunger D will be forced down with an
increased power. In this latter operation the pawls k, k, and racks 1, 1,
prevent the casual rising of the follower or plunger when the power is removed
from the shafts r, r, the pawls j and racks a forming the connection between
the cross head F and rack bars E, E. The relative size of the gearing
J, n, p, q, may be varied to suit particular cases. The movement of the cross
head F is of course quite small compared with the first movement of the
follower or plunger.
Having now described this Invention of "An Improved Press for Com-
pressing Substances for Packing in the Form of Bales or for other Purposes,"

page_text: and having explained the manner of carrying the same into effect, as com-
municated to me by my foreign correspondent, I claim, as the Invention
secured to me by Letters Patent as aforesaid, the mode of arranging and
actuating the plungers so that they may be moved at different speeds and with
different pressure or power according to circumstances.
In witness whereof, I, the said William Edward Newton, have here-
unto set my hand and seal, the Second day of May, in the year of
our Lord One thousand eight hundred and sixty-one.
