Improvements in and relating to Hutch Tippers for Coals and other
material.
1, JOHN SMITH of 49 Buchanan's Buildings, Low Blantyre Road, Hamilton,
Lanarkshire, Engineer, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to improvements in the construction of the revolving
cages or oscillating frames used at coal pit heads and stations for tipping and
discharging the loads from hutches or wagons. And the improvements comprise
new or improved arrangements and combinations of catch levers and mechanism for
automatically holding and locking the hutches while the tip cage is rotating, and
releasing them when they return to their normal position, while also enabling the
hutches to be run on to or off from the tip cage at either side.
Under one arrangement the improvements consist in mounting two transverse
spindles between and in loose end bearings in the rail frames, one near each side of
the tip cage. Each of these spindles would have hooks or catches mounted on it
near both of its ends, the gripping parts of the hooks facing outwards from both
spindles, and one of these catches on opposite diagonal ends of both spindles would
be formed with a projecting arm to which would be connected the one end of a link
or rod, having its other end attached to one of the ends of a horizontal two armed
oscillating lever fulcrumed on a vertical pin in the centre of the under frame of the
tip cage. A horizontal arm would be formed at the centre of this lever to project
out at right angles to it and be operated as hereinafter described by a vertical
oscillating lever loosely hung from a projecting stud bracket at its upper end, and
having a heavy, preferably segmental weight at its lower end. The action of the
improved mechanism is as follows. The loaded hutch is run on to the rails of the
tip cage from either side and its wheels rest in the usual recessed parts of same.
When the cage begins to move round on its usual edge pulleys to tip the wagon
and its contents, the vertical weighted lever begins to move to the opposite side
and in so doing acts on the radial projecting arm of the horizontal two armed lever
to oscillate same and through the connecting links turn the transverse spindles, so
that the hook catches on both spindles will embrace and steadily hold the wheel
axles of the hutch while the cage is rotating. After the rotating cage has passed
its tipping position the weighted lever will oscillate to the opposite side of cage
against a stop bracket, but in doing so will not interfere with the horizontal lever,
and the hook catches will still embrace and lock the axles of the hutch until the
cage has rotated round to its normal starting position, when the hook catches will
fall away by their own weight or gravity and permit the empty hutch to run off on
the rails from either side of the tip cage. A stop plate may project from the under
frame of tip cage to prevent the horizontal lever from moving too far when its
projecting arm is acted on by the vertical weighted lever.
Under a modified arrangement of my improvements I mount a longitudinal
spindle in bearings on the under frame of the tip cage between the lines of rails,
and I mount bevel wheels on the two ends of this spindle to gear with corresponding
wheels or pinions of half their size on each of the transverse spindles carrying the
hook catches, these wheels being boxed in to exclude dirt. The weighted vertical
oscillating lever is mounted by its top eye loose on the longitudinal spindle, and the
weight on its lower end is made adjustable by a shifting pinching screw and a series
of holes. A clutch is fixed on the longitudinal spindle over the weighted lever,
and has a segmental part cut away in it. With this arrangement when the cage
with the hutch on it begins to rotate round, the oscillated weighted lever will act

page_text: on one of the ends of the clutch and slightly turn the longitudinal spindle. The
wheels on the end of this spindle will act on the corresponding wheels of the two
transverse spindles and turn these with an increased rotation round and make their
hook catches engage and lock the axles of the hutch wheels while the tip cage is
rotating. After the tip cage has passed its unloading position, the oscillating
weighted lever will by gravity swing back to its starting position, and the open
segmental part cut out of the clutch will permit it to do so without acting on the
clutch. The hook catches will remain on the axles until the tip cage has returned
to its starting position, when they will fall away by gravity, and in doing so will
turn their spindles slightly round, and which action will also bring the one end of
the segmental clutch round ready for being acted on again by the weighted lever
when the next loaded hutch comes on to the cage.
Under another arrangement, instead of mounting bevel wheels on the longitudinal
and transverse spindles, I mount projecting arms or levers at right angles to each
other, those on the longitudinal spindle being double the length from their centre
of those on the transverse spindles. In this arrangement the vertical weighted
lever is keyed at its upper end on to the longitudinal spindle. When the tip cage
with the hutch on it begins to rotate the weighted lever will oscillate to the one
side and in so doing will turn the longitudinal spindle, and the two projecting arms
on this, will act on the arms at right angles to them on the transverse spindles and
turn these to put the hook catches on to the axles of the wheels of the hutch.
After the cage has passed its unloading tip position the return of the weighted
lever will simply turn the longitudinal spindle and its projecting arms, but not
interfere with the other arms or transverse spindles, which will be automatically
brought back to their starting position by gravity after the cage has returned to its
normal starting position.
Under another modification an oscillating lever would be fulcrumed on a bracket
at one of the ends of the cage, and project up at an angle and have a toothed
quadrant at its upper end which would engage with a toothed wheel on one of the
transverse spindles. A projecting arm would be formed on the lower end of lever
which would be acted on in passing one of the usual pulleys on which the cage
rotates and operate the lever to turn the transverse spindle on which the hook
catches are mounted, and be retained in this position by a catch on a hanging
weighted lever, preferably fulcrumed on the same bracket. The two transverse
spindles on which the hook catches are mounted would be connected by cranks and
a diagonal connecting rod, or by a chain or equivalent means, so as to make both
spindles and sets of hook catches work in unison in opposite directions. In this
arrangement the quadrant toothed lever is counterbalanced to bring the hook
catches out of action when the cage has returned to its normal starting position.

COMPLETE SPECIFICATION.
Improvements in and relating to Hutch Tippers for Coals and other
material.
I, JOHN SMITH, of 49. Buchanan's Buildings, Low Blantyre Road, Hamilton,
Lanarkshire, Engineer, do hereby declare the nature. of my invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement in writing, that is to say :-
This invention has reference to improvements in the construction of the revolving
cages or oscillating frames used at coal pit beads and stations for tipping and
discharging the loads from hutches or wagons. And the improvements comprise
new or improved arrangements and combinations of catch levers and mechanism for

page_text: automatically holding and locking the hutches while the up cage is Staining, and
releasing them when they return to their normal position, while also enabling the
hutches to be run on to or off from the tip cage at either side.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended five sheets of explanatory drawings, in which the same reference letters
are used to indicate corresponding parts in all the figures where shown.
Figures 1 and 2 on Sheets 1 and 2 are end and side elevations respectively of a
hutch and cage in their upright unlocked position.
Figure 3 is a view corresponding to Figure 2, but showing the hutch and cage
in the tilted locked position, and
Figure 4 is an inverted plan view corresponding to Figures 1 to 3, all illustrative
of one arrangement of my improvements.
Figures 5 to 8 on Sheet 5, illustrate views of modified arrangements of my
improved fittings herein referred to :-
!
Referring to Figures 1 to 4 :-Under this arrangement the improvements consist
in mounting two transverse spindles A, A', between and in loose end bearings A", A",
in the rail frames, one near each side of the tip cage. Each of these spindles A, A',
has hooks or catches a, mounted on it near both of its ends, the gripping parts of
the hooks facing outwards from both spindles A, A', and one of these catches on
opposite diagonal ends of both spindles A, A', is formed with a projecting arm a¹
to which is connected the one end of a link or rod a having its other end attached
to one of the ends of a horizontal two armed oscillating lever b fulcrumed at b¹, as
shown in Figure 4, on a vertical pin in the centre of the under frame of the tip
cage. A horizontal arm & is mounted or formed at the centre of this lever b to
project out at right angles to it and is operated as hereinafter described by a
vertical oscillating levere loosely hung from a projecting pin and stud bracket
at c', at its upper end, and having a heavy preferably segmental weight c" at its
lower end. The action of the improved mechanism is as tollows. The loaded
hutch B is run on to the rails B' of th tip cage C, from either side and its wheels W,
rest in the usual recessed parts of same.
When the cage C begins to move round
on its usual edge pulleys C, C', to tip the wagon B and its contents, the vertical
weighted lever c, c, begins to move from the position, shown in Figures 1 and 2, to
the opposite side and in so doing will act on the radial projecting arm of the
horizontal two armed lever to oscillate same and through the connecting links a², a²,
turn the transverse spindles A, A', so that the hook catches a, a', on both
spindles A, A', will embrace and steadily hold the wheel axles W', W, of the
hutch B while the cage C is rotating. After the rotating cage C has passed the
tipping position, shown in Figure 3, the weight c" will fall over against the pro-
jection on its rod or lever c, and the lever oscillate to come against a stop
bracket &, and the hook catches a will still embrace and lock the axles W₁ of
the hutch B, until the cage C, has rotated round to its normal starting position,
shown in Figures 1 and 2, when the hook catches a, a¹, will be liberated by the
weight cl falling down and the lever c, c', swinging back to its starting position
and permit the empty hutch B to run off on the rails from either side of the tip
cage C.
Under a modified arrangement of my improvements, as shown in plan view in
Figure 5 on Sheet 5, I mount a longitudinal spindle d in bearings d" on the under
frame of the tip cage C, between the lines of rails, and I mount bevel wheels d', d¹,
on the two ends of this spindle d to gear with corresponding wheels or pinions d', d³,
preferably of half their size on each of the transverse spindles A, A', carrying the
hook catches a, these wheels being boxed in to exclude dirt. The weighted vertical
oscillating lever c, o¹¹, shown in detached views Figures 6 and 7, is mounted at 8
by its top eye loose on the longitudinal spindle d, and the weight c on its lower
end is made adjustable by a shifting pinching screw d', and a series of holes do.
A clutch e, shown in Figures 6 and 7, is fixed on the longitudinal spindle d over
the weighted lever c, and has a segmental part e cut away in it. With this

page_text: arrangement when the cage C, with the hutch on it begins to rotate round, the
oscillated weighted lever c, cll will act on one of the ends of the clutch e, and turn
it to the position shown in Figure 7, and so slightly turn the longitudinal spindle d.
The wheels d', d', ou the end of this spindle d, will act on the corresponding
wheels d, d, of the two transverse spindles A, A', and turn these with an increased
rotation round and make their hook catches a engage and lock the axles W' of the
hutch wheels W while the tip cage C, is rotating. After the tip cage has passed
its unloading position, the oscillating weighted lever c, cl, will by gravity swing
back to its starting position, and the open segmental part e cut out of the clutch e
will, in the position shown in Figure 7, permit it to do so without acting on the
clutch e.
The hook catches a will remain on the axles W until the tip cage C has
returned to its starting position, when they will fall away by gravity, and in doing
so will turn their spindles A, A', slightly round, and which action will also bring
the one end of the segmental clutch e round to the position shown in Figure 6
ready for being acted on again by the weighted lever c c" when the next loaded
hutch comes on to the cage C.
с
Under another arrangement, shown in plan view Figure 8, instead of mounting
bevel wheels on the longitudinal and transverse spindles I mount projecting arms
or levers at right angles to each other, those d', d', on the longitudinal spindle d
being double the length from their centre, of those a, d, on the transverse
spindles A, A¹. In this arrangement the vertical weighted lever c, cl, is keyed at
its upper end at d on to the longitudinal spindle d. When the tip cage with
the hutch on it begins to rotate the weighted lever c c" will oscillate to the one
side and in so doing will turn the longitudinal spindle d, and the two projecting
arms d, d', on this, will act on the arms d³, d, at right angles to them on the trans-
verse spindles A, A', and turn these to put the hook catches a on to the axles W',
of the wheels W of the hutch. After the cage C has passed its unloading tip position
the return of the weighted lever c, c", will simply turn the longitudinal spindle d
and its projecting arms d' d' but not interfere with the other arms d', d, or
transverse spindles A, A1, which will be automatically brought back to their
starting position by gravity after the cage C has returned to its normal starting
position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
First. The arrangement of catch levers in combination with transverse spindles,
operated by mechanism on revolving cages or hutch tippers to automatically hold
and lock the hutches while the tip cage is rotating, and release them when they
return to their normal upright position, substantially as herein described in
reference to and by way of application shown in the accompanying drawings.
Second. In revolving cages or hutch tippers the fitting and use of catch levers
mounted on transverse spindles and actuated from a horizontal oscillating lever
which is in turn operated by a hanging or swivelling weighted lever, substantially
as and for the purposes herein described in reference to and shown in the accom-
panying drawings.
Third. In revolving cages or hutch tippers, the fitting and use of catch levers
mounted on transverse spindles, in combination with wheel or lever gearing
operated by an oscillating weight on a longitudinal spindle, substantially as and
for the purposes herein described in reference to and shown on Sheet 5 of the
accompanying drawings.
