PROVISIONAL SPECIFICATION.
Improvements in Oscillating Tipplers.
I, JAMES RIGG of No. 11 Queen Victoria Street in the City of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention consists of a tippler which oscillates only as distinguished from
those making a complete revolution or rotation my objects being:
-
Firstly, to avoid a fall of the coal or material tipped inseparable from tipplers
making the entire revolution whether its direction be backwards or forwards and
its consequent liability to breakage.
Secondly. Inasmuch as the two arcs forming the double oscillation viz: for-
ward for discharge and the return empty, together amount to about three fourths
of a revolution instead of the entire circle, greater expedition is secured.
Thirdly. The arrangement of cranks and link hereinafter described reduce the
speed of travel of the mouth of the tippler through the forward arc as it approaches
the point determined for delivery and further secures a quick return to the original
position.
*
Tipplers made in accordance with my invention may be either of the so-called
"through way" form for discharging the load from box tubs or corves over their
sides & permitting of the empties passing out from the opposite end to that at
which they entered, or they may be of the end tipping form, in which case the
tub or corve enters and returns over the same rails.
Either of these tipplers may under my Invention be actuated by power and that
of the "through way" form by the force of gravity alone.
The side tippler consists of two rings G appearing in Figs. 1 to 8
Sheets I & II of cast or wrought iron, steel or other metal and of
a sufficient internal diameter to admit of the tub or corve with its load freely
entering. The rings are connected in the usual manner and fitted with rails for
the tubs or corves and the tippler is carried upon four rollers on the axes O & P,
two under each ring. As nearly as may be in continuation of that side of the
tub, which is nearest to the belt or screen or receptacle on to which the coal or
other material is to be tipped. I fix a plate A. H. Figs. 1. to 6. Sheets I. & II.
vertical or nearly so, bétween and at right angles to the rings to receive and
prevent such coal or material from falling early in the forward oscillation of the
tippler, and, parallel with the top of the tub at a suitable & clear height above
the load it contains, I place a horizontal door W hinged at X, and so balanced
that though it yields to the pressure of the load about being discharged, it does
not prevent its departure, when the mouth A of the tippler arrived at the angle
determined for delivery. Preferably the rails are fixed in the tippler in such a
manner that the centre of gravity of the loaded tub shall be above the centre
of oscillation and slightly eccentric, with reference to the rings in the direction
in which it is desired to tip. The commencing movement forward is thus assisted.
by the weight of the coal and the return of the empty is similarly assisted by a
counterbalance weight S. suitably placed.

page_text: The power driven side tipplers made in accordance with my Invention are
actuated through an arrangement of linkwork & gearing of the description shewn
in Figs. 1 & 2 Sheet I. In Fig. 1, the tippler will be seen in the vertical position,
as it would receive a loaded tub, and in Fig. 2, it is in the act of delivery prior
to its return to the vertical position. The object intended to be accomplished
is the comparatively slow movement of the load forward through the arc A.C.D.B.
Fig. 1, and a rapid return through the same are after discharging its load. The
diegrams correspond with side elevations of the tippler G being one of the rings
revolving upon rollers upon the shafts 0 & P and one or both rings as
described hereafter, is attached a tooth or friction segment Z of sufficient length.
to permit of the toothed or friction segment M being always in gear during the
movement of the mouth of the tippler throughout the arc A.C.D.B. and its return.
By the application of a continuous circular motion to the shaft K, an oscillatory
motion with varying velocity is imparted to the tippler consequent on the arrange-
ment of link & gearing described hereafter.
Upon the shaft K is a crank K.L. to which I attach a link L.V. (Fig. 1.), this
link being the same length or thereabouts as the arm N.V. which is rigidly attached
to the spur segment M capable of oscillating upon the shaft N. To secure that
the arrangement of link and gearing cause an oscillation as distinguished from a
revolution, it is of vital importance that the shaft K, to which is attached the
crank K.L. be placed at a distance from the quadrant shaft N greater than the
length of the crank K,L, the path of the crank pin L through the circle A.C¹‚D¹‚B¹
Fig. 1 Sheet I, securing the oscillation desired whereas had the distance from
the shaft K to the shaft N been less than the length of the crank K.L. a revolution
of the shaft N with varying velocity would have been caused, and thus defeated
the object of my. Invention. The segment M. is geared into the small spur pinion
on the roller shaft 0 to the boss of which is keyed the spur wheel Y gearing into the
ring segment. The three shafts K,N and O are parallel to each other or
preferably for large tipplers, I place a segment in each ring, driven by two spur
wheels Y, one for each, these being either connected or separately actuated through
two of the segments M. and the corresponding spur pinions at O.
When the tippler is in the verical position A, Fig. 1, the crank K.J. is in a
direct line with the link L.V. It will be seen that the crank pin L travelling
through the circle A'C'.D.B. in the direction indicated by the arrow Q is
occupied during about three fourths of its revolution in causing the tippler to move
through the delivery arc A.C.D.B. and that the three equal portions of the crank's
travel A¹.C.-C.D. and D.B. move the mouth of the tippler much more slowly
from D to B during the period of delivery than through the arcs A.C. and C.D.
Referring to Fig. 2 Sheet I. the remaining portion of the travel of the crank
pin L, being about one fourth of its circuit, effects the quick return of the tippler
to the vertical position A, the path of the crank pin L being equally divided into
three parts BE, E¹.F., and F.A¹. corresponding with the return are B.E.F.A.
and causing a varying velocity, the slowest portion being that at which delivery
has been or is about being completed. It will be seen that a friction or other clutch
may be provided for throwing the shaft K into gear at the will of the brakes-
man, when the loaded tub is in the tippler, as well as an automatic arrangement
for throwing it out on the return of the tub empty. Suitable friction pulleys R,
will prevent all risk of the tippler rings G leaving their respective rollers as well
as securing continuous contact of the ring segments Z with their respective spur
wheels.
I also apply this arrangement of gearing to power driven side tipplers con-
structed generally as above described but exclusive of the horizontal balanced
door hinged at the point X.
In cases where power is not available or desired for the purpose of driving
the side tipplers of the "through way" type permitting of the loaded tubs forcing
empty ones out, I construct them in either of the manners, and with the modifica-

page_text: tions shewn in Figs. 3 to 8. Sheet II. which provide for their being operated
in both directions by the force of gravity.
In each of these figures, the parts common to Figs 1 & 2 Sheet I are indicated
by similar letters, but the brake necessary for the control of these automatically
acting tipplers may be applied in any of the methods, three being shewn in the
figures.
In Fig. 3, I arrange a toothed rack or friction are R', against the side of the
ring into which is geared a suitable toothed pinion L¹ or a friction roller, and on
its shaft is keyed a friction brake wheel T under easy control.
In Figs. 5 & 6 I control the automatic escillation of the tippler in both
directions by a friction roller or rollers V.V. acting preferably on the interior
surface of the ring G upon which the tippler revolves or upon a corresponding
ring or projecting segment attached to it for this purpose. For the two friction
rollers VV in Figs. 5 and 6 may be substituted a friction shoe K¹ on shoes
as shewn in Figs. 7 and 8.
The Brakes in any instance may be arranged to act simultaneously upon both
rings of these tipplers thus also operating to prevent them from leaving their sup-
porting rollers either at the moment of delivery or on their return to the vertical
position A.
For power driven tipplers partially inverting the tubs, when they enter endwise,
I arrange the link and gearing to secure an oscillation of varying velocity in the
manner shewn in Figs. 9, 10, and 11. Sheet III. Fig. 9, is an end view of the
tippler looking from a pit-bank, Figs. 10 & 11 being diagrammatic side
elevations. Of these, Figs. 9 and 10 shew it in the vertical position ready to
commence the forward oscillation and Fig. 11 having completed it at the angle
determined for the discharge of its load and subsequent return to the first position.
In this arrangement, the segment M gears direct into the spur wheel T the
driving power being applied to the sprocket or other pulley U, and otherwise
the description of gearing and link, as in Figs. 1 & 2 Sheet I may be applied to
Figs. 9, 10 and 11. Such detail as clutches for throwing into gear, and provision
for automatically throwing out of gear are purposely omitted in order that the
drawings and diagrams may for their essential objects be rendered more clear.
For these power driven end tipplers where the avoidance of breakage of the
mineral or material being tipped is not of the first importance, I omit the counter-
balanced horizontal door.

I, JAMES RIGG of No. 11 Queen Victoria Street in the City of London, Engineer,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
My invention consists of a tippler which oscillates only as distinguished from
those making a complete revolution or rotation my objects heing:-
Firstly: To avoid a fall of the coal or material tipped inseparably from those
tipplers making the entire revolution whether its direction be backwards or for-
wards and its consequent liability to breakage.
Secondly Inasmuch as the two arcs forming the double oscillation viz:-for-
ward for discharge and the return empty, together amount to about three fourths
of a revolution, instead of the entire circle greater expedition is secured.

page_text: :-
Thirdly The arrangement of cranks and link hereinafter described reduce the
speed of travel of the mouth of the tippler through the forward arc as it approaches
the point determined for delivery and further secures a quick return to the original
position.
..
Tipplers made in accordance with my Invention may be either of the so-called
Through way. "form of discharging the load from box tubs or corves over their
sides and permitting of the empties passing out from the opposite end to that at
which they entered, or they may be of the end-tipping form in which case the
tub or corve enters and réturns over the same rails.
Either of these tipplers may under my Invention be actuated by power and that
of the "through-way" form by the force of gravity alone.
The drawings left with my Provisional Specification, Figs. 1 to 11 on Sheets 1 II
and III are adapted in this complete specification and in addition the two sheets
IV. & V. Figs. 12 and 13 respectively.
The side tippler consists of two rings G, appearing in Figs. 1 to 8 Sheets I. & II.
& Figs. 12 & 13 Sheets IV. and V., of cast or wrought iron, steel or other metal, and
of a sufficient internal diameter to admit of the tub or corve with its load freely
entering. The rings are connected in the usual manner and fitted with rails for
the tubs or corves and the tippler is carried upon four rollers on the axes 0 and P,
two under each ring. As nearly as may be in continuation of that side of the
tub which is nearest to the belt or screen or receptacle on to which the coal or
other material is to be tipped, I fix a plate A.H., Figs 1 to 6 Sheets I. & II. and
Figs. 12 and 13, Sheets IV and V, vertical or nearly so, between and at right
angles to the rings to receive and prevent such coal or material from falling early
in the forward oscillation of the tippler, and, parallel with the top of the tub at a
suitable and clear height above the load it contains, I place a horizontal door W
hinged at X and so balanced that though it yields to the pressure of the load
about being discharged, it does not prevent its departure, when the mouth A of
the tippler arrives at the angle determined for delivery. Preferably the rails
are fixed in the tippler in such a manner that the centre of gravity of the loaded
tub shall be above the centre of oscillation, and slightly eccentric with reference
to the rings in the direction in which it is desired to tip. The commencing
movement forward is thus assisted by the weight of the coal and the return of
the empty tub is similarly assisted by a counterbalance, weight S. suitably placed.
The power driven side tipplers made in accordance with my invention are
actuated through an arrangement of linkwork and gearing of the description shewn
in Figs. 1 & 2 Sheet I. In Fig. 1, the tippler will be seen in the vertical position,
as it would receive a loaded tub, and in Fig. 2, it is in the act of delivery prior
to its return to the vertical position. The object intended to be accomplished
is the comparatively slow movement of the load forward through the arc A.C.D.B.
Fig. 1, and a rapid return through the same arc after discharging its load. The
diagrams correspond with side elevations of the tippler, G. being one of the rings
revolving upon rollers upon the shafts O. and P. and to one or both rings, as
described hereafter, is attached a toothed or friction segment Z, of sufficient length
to permit of the toothed or friction segment M. being always in gear during the
movement of the mouth of the tippler throughout the are A.C.D.B. and its return.
By the application of a continuous circular motion to the shaft K, an oscillatory
motion with varying velocity is imparted to the tippler, consequent on the arrange-
ment of link and gearing described hereafter.
Upon the shaft K. is a crank K.L. to which I attach a link L.V. (Fig. 1.), this
link being the same length or thereabout as the arm N.V. which is rigidly attached
to the spur segment M. capable of oscillating upon the shaft N. To secure that
the arrangement of link and gearing cause an oscillation as distinguished from a
revolution, it is of vital importance that the shaft K, to which is attached the
crank K.L. be placed at a distance from the quadrant shaft N. greater than the
length of the crank K,L, the path of the crank pin L through the circle A¹,C,D,B¹

page_text: Fig. 1, Sheet I, securing the oscillation desired, whereas had the distance from
the shaft K, to the shaft N been less than the length of the crank K.L. a revolution
of the shaft N. with varying velocity would have been caused and thus defeated
the object of my Invention. The segment M is geared into the small spur pinion
on the roller shaft O, to the boss of which is keyed the spur wheel Y gearing into the
ring segment Z. The three shafts K, N, and O, are parallel to each other, or
preferably for large tipplers I place a segment in each ring driven by two spur
wheels Y, one for each, these being either connected or separately actuated through
two of the segments M. and the corresponding spur pinions at 0.
When the tippler is in the verical position .A, Fig. 1 the crank K,L, is in a
direct line with the link L.V. It will be seen that the crank pin L, travelling
through the circle A.C.D.B. in the direction indicated by the arrow Q, is
occupied during about three-fourths of its revolution in causing the tippler to move
through the delivery arc A.C.D.B. and that the three equal portions of the crank's
travel A¹.C-C.D. and D.B¹. move the mouth of the tippler much more slowly
from D. to B. during the period of delivery than through the arcs A.C. and C.D.
Referring to Fig. 2 Sheet I. the remaining portion of the travel of the crank
pin L, being about one fourth of its circuit, effects the quick return of the tippler
to the vertical position A, the path of the crank pin L, being equally divided into
three parts BEEF. and FA¹ corresponding with the return arc of the tippler
B.E.F.A. and causing a varying velocity, the slowest portion being that at which
delivery has been or is about being completed. It will be seen that a friction
or other clutch may be provided for throwing the shaft K into gear at the will of
the Brakesman when the loaded tub is in the tippler, as well as an automatic
arrangement for throwing it out on the return of the tub empty. Suitable friction
pulleys R, will prevent all risk of the tippler rings G leaving their respective
rollers as well as securing continuous contact of the ring segments Z, with their
respective spur wheels.
I also apply this arrangement of gearing to power driven side tipplers, con-
structed generally as above described but exclusive of the horizontal balanced
Goor W, hinged at the point X.
In cases where power is not available or desired for the purpose of driving
the side tipplers of the "through-way" type permitting of the loaded tubs forcing
empty ones out, I construct them in either of the manners and with the modifica-
tions shewn in Figs. 3. to 8. Sheet. II. which provide for their being operated
in both directions by the force of gravity.
In each of these figures the parts common to Figs. 1. & 2. Sheet. I. are indicated
by similar letters but the brake necessary for the control of these automatically
acting tipplers may be applied in any of the methods, three being shewn in the
figures and the Banksman's direction determines the moment at which it should
be applied.
In Fig. 3, I arrange a toothed rack or friction are R¹, against the side of the
ring into which is geared a suitable toothed pinion L¹, or a friction roller, and on
its shaft is keyed a friction brake wheel T¹ under easy control.
In Figs. 5 and 6 I control the automatic oscillation of the tippler in both
directions by a friction roller or rollers V.V₁. acting preferably on the interior
surface of the ring G, upon which the tippler revolves or upon a corresponding
ring or projecting segment attached to it for this purpose.
For the two friction rollers V.V₁ in Figs. 5. and 6, may be substituted a
friction shoe K¹, or shoes as shewn in Figs. 7. and 8.
The Brakes in any instance may be arranged to act simultaneously on both
rings of these tipplers thus operating to prevent them from leaving their sup-
porting rollers either at the moment of delivery or on their return to the vertical
position A.
For power driven tipplers partially inverting the tubs when they enter endwise,
I arrange the link and gearing to secure an oscillation of varying velocity in the
manner shewn in Figs. 9, 10, and 11. Sheet. III. Fig. 9, is an end view of the

page_text: tippler looking from a Pit-bank, Figs. 10 and 11 being diagrammatic side
elevations. Of these Figures 9. and 10. shew it in the vertical position ready to
commence the forward oscillation and Fig. 11. having completed it and at the angle
determined for the discharge of its load and subsequent return to the first position.
In this arrangement the segment M gears direct into the spur wheel T. the
driving power being applied to the sprocket or other pulley U, and otherwise
the description of gearing and link as in Figs. 1. and 2. Sheet I. may be applied to
Figs. 9, 10 and 11. Such detail as clutches for throwing into gear and provision
for automatically throwing out of gear are purposely omitted in order that the
drawings and diagrams may for their essential objects be rendered more clear.
For these power driven end tipplers where the avoidance of breakage of the
mineral or material being tipped is not of the first importance, I omit the counter-
balanced horizontal door.
In Fig. 12, Sheet IV. is seen a side elevation of my power driven Balanced
Through-way oscillating side tippler and Fig. 13, Sheet V. is an end view of the
same. Like letters indicate like parts and the description given of the dia-
grammatic views Figs. 1. and 2. Sheet. I. may therefore be applied to these,
certain additional details being described below.
In the side elevation Fig. 12. the full lines shew the tippler in a position
corresponding with Fig. 1 Sheet I that is, having received its load and ready to
commence its forward oscillation and the dotted lines in the same fig. correspond
with the machine at the point of delivery on to the belt, screen, shoot or other
receptacle as in Fig. 2. The toothed segment %, when placed halfway between
the rings G.G. avoids all risk of straining or cross-winding and the internal
pulleys R.R. secure the grooved rings G.G. in position on their rollers at all
periods of the oscillation. One form of automatic "throw-off" is shewn in the
handle or lever T. pivotted at T2. and connected by the shaft S¹. to the friction
clutch F2. To set the gearing in operation the banksman by advancing the lever T₁
to the position, T3 Fig. 13. throws the clutch into gear and should he fail to
withdraw this lever on the return of the tub empty the projection P¹ operates
and produces this result when the insertion of another loaded tub removes the
empty one and soon at a pace only limited by the speed at which it is determined
the shaft K, shall travel.
To render the action of the projection P¹. more certain I may insert a sheet
of indiarubber at R. and R2. to permit the return motion of the tippler to slightly
exceed its normal limit.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I wish it to be under-
stood that I do not limit myself to the precise details herein described and shewn
on the drawings, as the same may be varied without departing from the nature
of my invention, and I declare that what I claim is:-
1. In a power driven oscillating Balanced Through-way side tippler, having a
counterbalanced horizontal door, the arrangement of link and gearing by which
a constant revolution produces a varying oscillation substantially as hereinbefore
described and illustrated in Figs. 1, 2, 12 and 13 Sheets. I. IV. and V.
2. In a power driven oscillating balanced throughway side tippler the arrange-
ment of link and gearing by which a constant revolution (produces a varying

roller brakes.
