"IMPROVEMENTS IN
in the County of Kent, Gentleman, for an Invention of
OR APPLICABLE TO PUGGING MILLS."
PROVISIONAL SPECIFICATION left by the said Richard Russell Gubbins at
the Office of the Commissioners of Patents on the 16th November 1880.
RICHARD RUSSELL GUBBINS, of 17, Park Road, New Cross, in the County of
Kent, Gentleman. "IMPROVEMENTS IN OR APPLICABLE TO PUGGING MILLS."
This Invention relates to certain improvements in or applicable to pugging mills
or apparatus for incorporating material, whether such material be dry or wet, the
object being to ensure a more perfect intermixing of the ingredients to treat a
greater quantity of material at one and the same time, and to effect such incorpo-
ration of the materials more rapidly and perfectly than at present can be done, and
at same time to prevent clogging and complication of the parts of the pug beaters,
blades, or arms.
In carrying the Invention into practice, transverse shafts carrying the pug
beaters, blades, or arms are mounted upon framing upon outside of the pugging
box, and said beater shafts pass through a slot or slots in the side or sides of the
pugging box and receive motion through winch or pulley through gearing, by
which they are geared together, and said gearing drives an eccentric which
actuates a link piece attached to the pugging box, which said pugging box is
capable of end-wise movement in a to and fro direction by said link motion.
The beater shafts pass through the sides of the pugging box, and are furnished
with packings which provide for keeping the said pugging box tight whilst
allowing of the said to and fro motion of the said pugging box, and the beaters
are either rods passed through or carried upon said shafts, or are discs or blades
set obliquely or otherwise upon the shafts, and of well known or convenient
shape or kind, according to the purpose to which the pugging mill is to be
applied.

page_text: The function of the apparatus is to pug or stir the ingredients constituting the
pug-mass, and by the traversing action of the pugging box to force the material
against and through the beaters, so cutting the pug-mass through and through in
addition to the ordinary stirring action, whereby every particle of the pug mass
is most thoroughly and effectually traversed and the whole intimately incorporated
at the same time that such traversing action ensures that no part of the mass
shall remain stationary or clogged in any one or other part of the pugging box.
By fitting one end of the pugging-box with a sliding jacket or shoe, whether the
apparatus be arranged horizontally or vertically, a trap in the shell or skin of the
pugging box or jacket may be opened from time to time for the partial discharging
of the pugged mass, and fresh quantity can be supplied at the other or upper end
through a head for securing a continuous action through the mill.

RICHARD RUSSELL GUBBINS, of 17, Park Road, New Cross, in the County of
5 Kent, Gentleman. IMPROVEMENTS IN OR APPLICABLE TO PUGGING MILLS."
This Invention relates to certain improvements in or applicable to pugging mills
or apparatus for incorporating material, whether such material be dry or wet, the
object being to ensure more perfect intermixing of the ingredients, to treat a
greater quantity of material at one and the same time, and to effect such incorpo-
Oration of the materials more rapidly and perfectly than at present can be done, and
at same time to prevent clogging and complication of the parts of the "pug'
beaters, blades, or arms.
و"
In carrying the Invention into practice transverse shafts carrying the pug
beaters, blades, or arms are mounted upon framing upon outside of the pugging
box, and said beater shafts pass through a slot or slots in the side or sides of the
pugging box, and receive notion through winch or pulley through gearing, by
which they are geared together, and said gearing drives an eccentric which
actuates a link piece attached to the pugging box, which said pugging box is
capable of end-wise movement in a to and fro direction by said link motion.
The beater shafts pass through the sides of the pugging box, and are furnished
with packings which provide for keeping the said pugging box tight whilst
allowing of the said to and fro motion of the said pugging box, and the beaters
are either rods passed through or carried upon said shafts or are discs or blades
set obliquely or otherwise upon the shafts, and of well known or convenient
shape or kind, according to the purpose to which the pugging mill is to be
applied.
The function of the apparatus is to pug or stir the ingredients constituting the
pug-mass, and by the traversing action of the pugging box to force the material
against and through the beaters so cutting the pug mass through and through in
addition to the ordinary stirring action, whereby every particle of the pugged mass
is most thoroughly and effectually traversed and the whole intimately incorporated
at the same time that such traversing action of the box and consequently of the
mass against the beaters ensures that no part of the mass shall remain stationary or
clogged in any one or other part of the pugging box.
By fitting one end of the pugging box with a sliding jacket or shoe, whether the
apparatus be arranged horizontally or vertically, a trap in the shell or skin of the
pugging box or jacket may be opened from time to time for the partial discharging
of the pugged mass, and fresh quantity can be supplied at the other or upper end
through a head for securing a continuous action through the mill.
In order that the Invention may be well understood, I have hereunto aunexed a
Sheet of Drawings, wherein is represented apparatus constructed according to this
Invention for the purpose of carrying the same into practical effect, wherein
Fig. 1 is a plan or top view of the apparatus.
Fig. 2 is a front elevation with the door of the pugging box removed; Fig. 2",
ike elevation of part of door; and Fig. 2b a section at line c, c, Fig. 2ª, showing
letail of door fitting.
Fig. 3 is a transverse section at line a, a, Figs. 1 and 2, and looking from right
of said figures; and Fig. 4 a like section at b, b, Figs. 1 and 2.
A is framing upon which the carriage way of the traversing pugging box B is
upported, and A' framing supporting standards A³, and A* carrying the driving
nechanism; C is a knife edge rail; D, vee wheels running thereon. E is a neck on
-

page_text: axle of one wheel of carriage to receive one end of a link rod, serving to connect
the carriage with the crank arm F to effect the to and fro motion of the box B (the
link rod is not shown on the Drawings, but is indicated in Fig. 2 by line d, d).
G is the door of box B hinged at H, and secured by the swinging pins carrying fly
nuts I, said swinging pins turning on studs and taking into the ears K of the door
for locking same when in use or when the pugging operation is completed for
facility and readiness of opening and for the removal of the pug mass as and when
required. As before described, a cover and hopper and also a trap may be supplied
to the box B for continuously feeding and discharging the material operated upon.
L are the pugging blades, here shown in disc form, but may be rods or arms passed
through the shafts M, M', or of any desirable well known form; the pugging blades
are not shown in Fig. 1. The shafts M, M', pass through the slot or opening N of
the box B, and the packing of these shafts is effected by the face N₁ of opening N
sliding and bearing against the face O provided on the standard As of the machine.
P is a guide piece or face of or on the standard As, against which bears and slides
the piece Qbolted on to box B to support and guide the said box B in proper
position. The set screw and yoke R is for purpose of withdrawing the shafts M, M¹,
from the pugging blades so as to release the box B, when same may be required to
be removed on completion of the pugging operation, the forked ends R¹ of yoke R
engaging with the collars and necks S, S₁, of shafts M, M'.
The actuating of the apparatus and the gearing is from the driving wheel T on
shaft T', off wheel T2, on to wheel T3 of shaft M¹, and thence to wheel T of shaft M.
The pulley U of shaft M¹ drives by chain the wheel V ("Ewart's Patent Chain
Pulleys" being shown in Drawings), and said wheel V is carried on shaft W
carrying the crank F for actuating the box B in its to and fro movement simul-
taneously with the working of the pugging blades L.
Having now described the said Invention in such wise that the same may be
readily carried into practical effect, I claim,-
First. The improvements in pugging mills or apparatus for incorporating or
mixing materials, constructed and operating as and for the purpose herein set forth
and described in reference to and shown by the Figures of the accompanying|
Drawings.
Second. In pugging mills the combination of the traversing box B with the
pugging blades (discs, arms, or rods) L and shafts provided with packings N, O, as
and for the purpose herein set forth and shown by the Drawings.
In witness whereof, I, the said Richard Russell Gubbins, have hereunto set my
hand and scal, this Tenth day of May, in the year of our Lord One
thousand eight hundred and eighty one.
