JAMES JENKINS, of Cardiff, in the County of Glamorgan, Millwright and
Engineer. "IMPROVEMENTS IN CLEANING TIN AND TERNE PLATES, AND IN THE
MACHINERY OR APPARATUS TO BE EMPLOYED THEREIN."
This Invention relates to the cleaning or removal of the oil and grease from tin
and terne plates after the process of coating or tinning, and consists in the employ-
ment for that purpose of one or more feed rollers of any suitable material, disposed
either vertically, horizontally, or at any intermediate angle in front of a box or
casing filled with bran, sharps, sawdust, or other cleansing material. On the.
opposite side of the said box or casing are provided delivery rollers for receiving
the plates from the said casing as they pass through the bran or sharps from the
feed rollers. The feed and delivery rollers are caused to revolve at any required.
speed by the aid of gearing, or otherwise, and receive in addition to their rotary.
motion an endwise or longitudinal reciprocating motion either in a vertical or other
direction, according to the position in which they are placed, such longitudinal
motion being obtained by various well known mechanical contrivances, as for
example, by an eccentric or by causing the ends of the roller spindles to be acted
upon by a cam path, groove, or projections in the face of the actuating wheel or
wheels, whilst a spring is caused to bear against the opposite ends of the spindles.
Thus, when the wheels revolve the feed and delivery rollers which are pressed
together in pairs by springs, weights, or screws, and revolve in the same direction
will receive a longitudinal reciprocating or "shogging" motion as well as a rotary
motion, thereby not only feeding or passing the plates to be cleansed through the.
bran or other cleansing material in the box or casing, but at the same time working.
such plates up-and-down vertically, or to-and-fro horizontally as the case may be in:
the bran, thereby thoroughly and effectually cleansing them..
In some cases I employ stationary or revolving sheep skin or other suitable.
dusters disposed either vertically or horizontally, and of spiral or other convenient.
form for the purpose of dusting the plates as they pass from the delivery rollers.

"
JAMES JENKINS, of Cardiff, in the County of Glamorgan, Millwright &
Engineer. IMPROVEMENTS IN CLEANING TIN AND TERNE PLATES, AND IN THE
MACHINERY OR APPARATUS TO BE EMPLOYED THEREIN."
My said Invention relates to a mode of & apparatus for cleaning or removing
the oil & grease fom tin & terne plates after such plates have undergone the process
of coating or tinning, & consists in the employment for that purpose of one or more
pairs of feed rollers of any suitable material, disposed either vertically, horizontally,
or at any intermediate angle in front of or beneath a slot or opening in a box or
casing filled with bran, sharps, sawdust, or other cleansing material. On the
opposite side of the said box or casing are provided a pair of delivery rollers for
receiving the plates from the said casing as they pass through the bran or sharps
from the feed rollers. The feed & delivery rolls are caused to revolve at any
required speed by the aid of gearing, or otherwise, & receive in addition to their
rotary motion an endwise or longitudinal reciprocating or shogging motion, such
longitudinal shogging motion being obtained by any well known mechanical
arrangement, as for example, by an eccentric or crank pin acting upon a vibrating
or shogging frame carrying the bearings of the said rollers. The said rollers are
pressed together in pairs by springs, screws, or otherwise, so as to, nip the plates, to
be cleansed between them, and as both the feed & delivery rollers receive a longi-
tudinal reciprocating or "shogging" motion as well as a rotary motion, they not
only feed or pass the plates to be cleansed through the bran or other cleansing.
material in the box or casing, but at the same time impart to the said plates during
their passage through the bran box a rapid vibratory motion in a direction at right
angles or thereabouts to that of their passage through the said box or casing,
thereby thoroughly & effectually cleansing them.
In some cases I employ stationary or revolving sheep skin or other suitable
dusters disposed either vertically or horizontally, & of spiral or other convenient.
form for the purpose of dusting the plates as they pass from the delivery rollers.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same,, & for that purpose shall refer to the several
Figures on the explanatory Sheet of Drawings hereunto annexed, the same: letters
of reference indicating corresponding parts in all the Figures..
.
Fig. 1 of my Drawings represents a side elevation of my, improved tin or terne:
plate cleansing machine; Fig. 2 is. a front elevation, of the same; Fig. 3 is a plan
corresponding to Fig. 1; Fig. 4 is a vertical section on an enlarged, scale. of the bran
box & feeding & delivering rollers, & Figs. 5 & 6 représent respectively a detail,
transverse section & plan of the bran box detached.,
A, A, are the standards of the machine forked at. their upper ends & carrying
within the forks two side plates. B, B, connected together by tie rods, & provided with!"
projecting lugs or slides a, a, which work in slots B in the standards (see Fig. 2)..
Each side plate is slotted to carry the bearings of the: feed &, delivery rollers c, c,
& c, c, extending between the side plates.. Between these side plates & also
between the feeding & delivery rollers there is mounted by means of lugs resting
upon & secured to the standards a box or receptacle C (Fig. 4), for containing the
bran, sharps, or other suitable material for cleansing the tin or terne plates d to be:
operated upon. A slot or oblong: opening is made in the bottoin of the said box
immediately above the feed rollers c, c, as shown more clearly in Fig. 4, for the
passage of the plates. In the centre of one of the side plates there is a stud pin. D:
upon which is mounted so as to turn freely the pulley E & gear wheel e cast in one

page_text: (shown dotted in Fig. 1), the gear wheel e gearing into corresponding toothed
wheels f, f, mounted respectively on one of the axles of the two pairs of feed
& delivery rollers c & c. The rollers in each pair are pressed together by
tightening screws acting upon. their.. bearings or by other suitable contrivances,
cushions of india rubber being by preference interposed between the screws & the
bearings to afford a yielding pressure or nip between the rollers.. India rubber
washers are also by preference interposed between the ends of the rollers & their
bearings to prevent jarring when at work. The end of the stud pin D is connected
by a short link F to an adjustable crank pin g in a slotted disc mounted on the
upper end of the vertical shaft G, which works in bearings at h & i, & is driven
from the first motion or driving shaft H by the bevel gearing I. The driving shaft
carrying fast & loose driving pulleys K & K transmits its motion by the crossed
strap & pulley L to the small pulley E & gear wheel e. An endless feeding
apron M serves to convey the plates d in regular succession to the feeding
rollers c, c.
This apron travels in the direction of the arrows, & is driven from the
first motion shaft by the spur wheel N, which gears into the adjustable carrier or
intermediate wheel O mounted in the swinging arms P, & gearing also into a spur
wheel Q on the axle of the driving roller R of the apron. The adjustable bearings
of this roller are provided with lugs carrying a spindle S on which are mounted
spur pinions T in gear with rack teeth formed on the edges of the curved slotted
frames U, within which the bearings or the roller R are free to slide up or down,
they being fixed at any desired elevation by pinching screws or nuts. By turning
the spindle S by the winch handle V, the delivery end of the apron can be raised
or lowered at will to suit the beights of the plates. These plates are maintained in
a nearly upright position on the apron by the supports k carried thereby (see
Fig. 1). The apron should be so adjusted as that the upper edges of the plates as
they are carried forward shall be caused to enter between the feed rollers set at an
angle for that purpose, & be caught thereby. When the machine is set in motion,
the plates travel towards the revolving feed rollers c, c, are gripped thereby, & passed
through the bran box until they are caught by the delivery rollers c', c¹. As the
feed & delivery rollers receive a rapid shogging or to-&-fro motion longitudinally,
the plate whilst being held by them & passing through the bran will also be
rapidly reciprocated laterally, thereby producing a most efficient rubbing or
cleaning action of the bran thereon. On issuing from the delivery roller c¹, the
plates may be dusted by means of sheepskin dusters, which may be rotated or
otherwise actuated from the machine itself. A bow or other spring W may be
arranged so as to bear against one end of the vibrating frame if desired to prevent
jarring and assist its rapid vibration.
Having now described & particularly ascertained the nature of my said Invention
& the manner in which the same is or may be used or carried into effect, I would
observe in conclusion that what I consider to be novel and original, & therefore claim
as the Invention secured to me by the hereinbefore in part recited Letters Patent
is,-
First. The system or mode of cleaning tin & terne plates after they have been
coated or tinned by causing them to be traversed through a receptacle containing
bran, sharps, or other suitable cleaning material, and at the same time to receive a
lateral or shogging vibratory motion therein produced mechanically by the aid of
longitudinally, reciprocating, or vibratory feed & delivery rollers or their equivalent,
substantially as herein before described.
Second. The combination in apparatus for cleaning tin & terne plates of a box or
receptacle containing bran, sharps, or other suitable cleansing material with
revolving feed & delivery rollers, such rollers receiving a longitudinal, recipro-
cating, or vibratory motion, & working in conjunction or not with sheepskin or
other suitable dusters for dusting the plates as they issue from the delivery rollers,
substantially as hereinbefore described.
Third. The peculiar combination of the adjustable endless feeding apron carrying
supports for the plates to be cleaned with the vibratory feed and delivery rollers,

page_text: and the box or casing containing, bran, sharps, or other suitable cleansing material
arranged to operate together, substantially in the manner & for the purpose herein-
before described and illustrated by my Drawings.
In witness whereof, I, the said James Jenkins, have hereunto set my hand
and seal, this 4th day of March, in the year of our Lord One thousand
eight hundred and eighty.
JAMES JENKINS. (L.S.)
