States of America COMPLETE SPECIFICATION.
I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Engineer. do hereby declare the nature of this Invention for "IMPROVEMENTS
IN RUMBLES FOR SCOURING CASTINGS, AND CRUSHING AND WASHING ORES, AND
THE LIKE," [a communication,] and in what manner the same is to be performed,
to be particularly described, and ascertained in and by the following statement:-
My Invention relates to improvements in rumbles for scouring castings and
pulverizing and washing ores or other materials.
The objects of my invention are:-
First to provide a rotating cylinder or drum in which the castings or other
articles are placed having inlet openings with elevating buckets at one end and
outlet openings at its opposite end through which water or other clensing element
passes contained in a tub or tank upon and within which tank the said cylinder is
suspended and journaled.
Second to provide in connection with said rotary cylinder a displacer adjustably
mounted within said tub to regulate the supply and depth of water in the
cylinder.
The features of my Invention will appear from the following description and will
be clearly defined by the claims.
Figure 1 is an end elevation of the machine embodying my Invention showing
the revolving cylinder of a formn especially adapted for cleaning castings mounted
upon and partially within a water tank or tub in connection with an adjustable
water displacing apparatus.

and washing ores; in this instance a pear shaped drum is used.
Figure 7 is a transverse end sectional elevation of another modified form of drum
showing the water elevating bucket constructed on its periphery between two
heads at the water inlet end of the cylinder adapted for pulverizing and washing
ores and cleaning castings.
Figure 8 is a longitudinal sectional elevation of another modified form of
apparatus showing two drums one mounted at each end of a revolving shaft also
adapted for pulverizing and washing ores.
Figure 9 is a longitudinal sectional elevation of another modified form of drun
shown in connection with inclined amalgam coated plates or shelves adapted for
pulverizing washing, and separating the more precious metalliferous ores.
Figure 10 is a transverse section of another modified form of drum showing
curved water elevating buckets which are arranged between two disks at the
inlet head of the cylinder similar to that shown in Fig. 7.
A represents a tank or tub of any desirable form for holding water or other
cleansing element, lines xx in the various Figures of the Drawings indicate the
level at which the water is filled in the tub.
aal represent a supporting and sustaining frame at both ends of tub A. B is a
cylinder or drum suitably mounted upon a horizontal revolving shaft C which is
journaled in bearings bb on the tub or the end frames a so that the drum shall bo
partially suspended within said tub. B¹ B" represent the end heads of drum B both
being provided with openings i for the feed and discharge or overflow of
water. eclare ribs, and arins formed upon the heads B' B".
B is a water feed or intet head each of the openings thereof being provided
with buckets D. The buckets 1 are chambers formed by means of plates covering
a portion of the space between the ribs and arms all as shown in Figs. 1 and 2 s
as to leave the sides opposite the ribs open and serve to scoop up the water into
which they dip raising a portion of the same and conducting it toward the axis or
shaft C where it is discharged through openings into the cylinder.
The raising of the water by the buckets into the cylinder at one end causes a
circulation or current therein and preserves a slight overflow or dischargo at the
opposite end and thereby drains off the lighter waste matter occasioned by the
washing of the castings or other material placed therein. The water discharge is
from the cylinder into the tank so as to be used repeatedly and thereby fully
utilize it.
In Figs. 1. 2. and 3 I have shown the cylinder of polygonal or angular form in
this instance an octagon. When used for cleaning small castings 1 prefer to
construct the faces of wood and heads B B" of metal as wood and water
combined act as a sound deadener and only a very slight rattling of the castings
can be heard when the drum is in motion.
In order to feed material such as ore to to the machine while the cylinder is either
in motion or at rest, I provide a spout E having at its lower end an apron or
guarde which approaches the face of the buckets D as near as possible and
discharges the material into the buckets through their open sides which in turn
feed it to the cylinder.
The spout E can bo supported in any suitable manner that will hold it off from
contact with the revoiving cylinder and convey the material from any source of
supply as desired.
F, represents a door closing an opening made in the cylinder B for the charge and
discharge of the materials therein. The door opening F may be used in lieu of the
spout E, e, as a means of feeding inaterial to the cylinder when at rest but its
principal object is to discharge the material from the cylinder.
In treating ores in my machine it is especially desirable to have an apparatus for
regulating the depth of water in the cylinder.
In Figs. 1 and 5 I have shown one of the preferred forms used in connection
with my machine. It is composed of a long box, block, or vessel G, having vertical

page_text: strips or sides g, at its opposite ends which move in-ways g' constructed on the
inner faces of the tub A, and projecting upward therefrom to admit of an extended
upward movement of box G, so that it may be held and suspended at any point
within the water or absorbed by it as desired.
f, represent pins passing through holes in the guides and extension g' in and
into holes in the slides g on the ends of the displacer to sustain the box desirable
position The displacement of the water caused by the lowering or imm-rsing of the
box G therein, raises it to the desired level in the cylinder which can be in tintained.
at all times during the operation of the machine at the will of the operator.
The operation of tho machine is as follows:-
The castings, sweeping, or ashes, containing metal dust and scraps or other
material to be cleaned or otherwise treated, are placed in the cylinder through the
door For the feed spout E The tub is filled with water up to line xx.
Motion being imparted to the cylinder, it revolves with its lower portion
containing the castings or other articles immersed in water.
In the rotation of the cylinder sand, scale and other dirt are readily removed from
the castings by natural atrition and the water which, being agitated, carries off the
sand and other light material in the overflow thereof through the ports or outlet
openings h.
The castings when sufficiently scoured can then be removed from the cylinder
through the door opening F.
In Figs. 4, 6, 7, 8, 9, and 10, I show modified forms of tumbling cylinders and
different ways in which they are mounted but all possess the same broad feature
as described in connection with the form shown in Figs. 1, 2 and 3.
The form shown in Fig. 4 consists in a spherical shell with an orifice or opening h
in its face and through which the material is inserted and extracted.
The shell is mounted on the end of a revolving shaft which is suitably supported
in bearings on the tub and suspended so as to be partially immersed in the water
contained in said tub. D represents the water raising buckets; on that face of the
shell connected with its driving shaft i are the dip-openings of the buckets and i¹
the discharge opening into the shell.
This form of shell shown in Fig. 4 is especially adapted for pulverizing and
washing ores.
In the operation of this device for treating ores, water is placed in the tub up to
the line or level xx. When the ore is charged into the shell it will to a greater
or less extent absorb the water so that it will fall below the said level and in order
to maintain the proper level at all times for the successful operation of the machine
I have provided in connection with the shell or cylinder, the displacer G which as
liereinbefore described can be adjusted vertically so as to raise or lower the water
as described.
While the ore is absorbing the water the displacer G, may be lowered, when the
water will rise and fill the shell to the desired level The action of the buckets on
the water to raise it and discharge it into the shell and the passage or the circu-
lation of the water through and out of the shell are identical with that described in
connection with the device shown in Figs. 1, 2 and 3.
When the washed ores are to be removed from the cylinder or shell the water
can be lowered by raising the displacer and a scoop, shovel or other instrument
inserted through the opening h.
The modified form shown in Fig. 6 is similar to that shown in Fig. 4 excepting
that the shell is pear shaped instead of spherical and its inner faces are provided
with radial ribs J, J', the ribs J being curved and terminating about midway
between the ends of the shell and the ribs J¹, arranged alternately between the
ribs J, projecting therefrom up to the mouth or opening where they taper to
a point.
Ribs J, J', cause resistance on the inside face of the shell with which the ore
comes in contact during the revolution of said shell.

page_text: Thus the ore is carried around, with the shell, a portion of its revolution and
thoroughly agitated and pulverized by being thrown against the ribs and also
materially advanced in its washing and separation.
The overflow and radial ribs carry off the lighter materials in to the body of
water in the tub as in the other devices herein-before described.
The ribs are made in division and alternating as shown, in order that the
material may not be carried off bodily or too rapidly toward the opening h.
The elevating buckets are similar to those shown in Fig. 4 excepting that the
head is flat instead of curved.
The entrance and exit of the water is identical also the manner in which the
shell is mounted on the end of the driving shaft. In Figure 7 I have shown a
modified form of water elevating buckets which may be used on either of the
shells described and shown herein.
The view shows a transverse sectional elevation of the water inlet head of thic
cylinder with the end plate or disk removed 1), represents the buckets which
instead of being arranged so that they dip the water from the end face of the
cylinder are so arranged that they dip the water from the preiphery of said
cylinder. There is an annular partition or ring arranged between two disks one of
which is not shown and forming the water chamber M and parts of the
buckets D. m are the outlet openings of the buckets into the chamber is a
central orifice in the inner head for the passage of the water from chamber M
into the cylinder.
In Fig. 8 I have shown another modified form of cylinders; two such cylinders
are shown one on each end of a driving shaft mounted on bearings between the
cylinders and having intermediate driving pulley or gear n. The cylinders are
plain round drunis cach being provided with flat heads B B the head B¹ being
the one having the water elevating buckets and the head B being the one for the
charge and discharge of the material placed in the cylinder through the orifice h
which orifice coïncides with those described and shown in Fig's. 4 and 6.
The buckets shown in both cylinders are the same as shown in Fig. 6 excepting
that those in the right hand cylinder dip from the periphery instead of from the
end face.
The operation of these cylinders is identical with those above described and it
will not be necessary for me to describe it.
In Fig. 91 have shown another modified form of cylinder It is mounted in the
same manner as the cylinder shown in Fig. 1. on a through shaft suitably journaled
in tearings on the tub this cylinder is of somewhat conical shape the inclino
thereof causing the heavier material to be drawn towards and settle in the larger
or water inlet end the lighter particles being carried off by the current occasioned
by the elevation of the water by the buckets and its discharge or overflow through
the exit orifice.
Spider arms connect the hub o with the exit orifice head B" of this cylinder,
which arms are not shown.
The water elevating buckets are the same as those above described in connection
with Figs. G and S.
P, are inclined ordinary amalgam coated plates arranged beneath the cylinder to
catch the overflow and are practically designed to separate and collect ore's
containing precious metal that escape from the cylinder in said overflow.
In Fig. 10 I have shown another form of elevating buckets. These buckets are
arranged between two disks or heads in a similar manner to those described and
partly shown in Fig. 7 but they are curved from the axis radially the water
chamber in this device being absent.
The inlet opening or orifice to the cylinder is like that shown in Fig. 7 and
formed in connection with the inner disk or cylinder head proper as in that Figure.
There, are discharge openings of these buckets emptying the water at the axis of
the cylinder as in all the views shown in the Drawings excepting Fig. 7.

page_text: I am aware that it has been proposed to supply water to a revolving cylinder by
means of buckets communicating with the interior of near one end the said
buckets lifting water from a tank beneath the cylinder and therefore lay no broad
claim to such feature.
My Invention differs from such constructions in having contracted open ends to
the cylindor and in introducing the water into the cylinder through such
contracted ends by means of the bucket communicating therewith instead of
directly with the cylinder through its periphery.
Having shown herein various modified forms of cylinder and numerous ways in
which the water elevating buckets may be constructed and arranged, it is obvious
still farther modifications in construction could be shown and still bo within tho
Scope of my Invention.
In order to pulverize ore, or other articles, boulders or heavy balls of iron or
other suitable material may be inserted in the shell or cylinder togather with the
material to be acted upon. In the revolution of said cylinder or shell the balls will
roll over and upon one another and thereby crush or pulverize the oro that comes
between them.
