APPARATUS FOR HAULING CORVES, TUBS, AND OTHER VEHICLES ON TRAM-

PROVISIONAL SPECIFICATION left by the said James Pease at the Office
of the Commissioners of Patents on the 24th August 1878.

"IMPROVEMENTS IN THE MEANS AND APPARATUS FOR HAULING CORVES, TUBS, AND
OTHER VEHICLES ON TRAMROADS, AND FOR ATTACHING AND DETACHING THE SAME
TO AND FROM THE HAULAGE CHAIN OR ROPE,"
This Invention relates to means and apparatus for attaching corves, tubs, trams,
and similar vehicles to haulage chains or ropes and detaching them automatically,
and is chiefly applicable for use in collieries, mines, and quarries, where endless
ropes or chains are employed for hauling the minerals and other materials.
This Invention consists in an improved gripping coupling connecting the corve
to the rope, in combination with inclined slides or guides fixed in the tramroad to
release the said gripping coupling from the rope automatically.
The upper portion of the coupling can be of the form of an ordinary hook, and
the lower portion thereof has the form of a pair of gripping tongs which can be
tee shaped at their extremities, and which are bowed or hollowed out to fit on to
the rope or chain. Over the shanks or stems of the tongs is placed a collar or
ferrule, which slides thereon and prevents the jaws of the tongs opening when a
corve is being hauled thereby. The inclined slides or guides are fixed at the point
where it is desired to cease hauling and disengage the corves from the rope. The
inclined slides are constructed and fixed so that the rope or chain and the lower
extremity of the coupling can pass between them freely, but so as to lift the collar

page_text: or ferrule up the shanks or stems and above the joint of the tongs, and thus allow
them to open outwards and so drop the rope or chain..
In carrying into effect this Invention the coupling hook is attached to the corve,
and the collar (surrounding the shanks of the gripping tongs) being raised the rope
is inserted in the tongs, the collar is then lowered, thus securing the coupling and
corve firmly to the rope; the corve will then travel with the rope, and when it
arrives at the inclined slides. the rope and lower extremity of the gripping tongs
pass between the said inclined slides, but the collar passes over the said inclined
slides and is raised up the tongs, by which means the rope is released from the
coupling and corve.
The endless rope or chain can have continuous motion, and the corves can by the
above-described means and apparatus be attached to and detached from the
travelling rope at any convenient time and place..

'IMPROVEMENTS IN THE MEANS AND APPARATUS FOR HAULING CORVES, TUBS, AND
OTHER VEHICLES ON TRAMROADS, AND FOR ATTACHING AND DETACHING THE SAME
TO AND FROM THE HAULAGE CHAIN OR ROPE.".
This Invention consists of a gripping coupling or clip for attaching corves to an
endless moving rope, in combination with inclined slides or guides fixed in the
tramway or tramroad, constructed substantially as herein-after described and
illustrated in the accompanying Sheets of Drawings, and for the purpose of hauling
the said corves along the tramroad and automatically detaching them from the
moving rope at any desired point.
The clip is attached to the corves and to the haulage rope by hand, and the clip
and corves travel with the haulage rope until they arrive at the inclined slides or
guides where the clip is detached automatically from the haulage'rope, and the further
progress of the corves is stayed although the haulage rope continues to travel.
By these means and apparatus the haulage rope can have continuous motion, and
the corves can be attached to and detached from the said moving rope at any
desired point.
In the accompanying Sheets of Drawings,-
Fig. 1 shews a general view of the apparatus for carrying into effect this
Invention, together with the corves and rope as connected together in working
order. The corves G, G, G, are coupled by the clip H to the haulage rope J, the
said corves being drawn in the direction of the inclined slides or guides K.
Fig. 2 shows a sectional elevation of the inclined slides or guides K taken
through the dotted line E, F, (Fig. 3), and Fig. 3 shows a plan of the same.
Fig. 4 shows a transverse section of part of the tramroad and inclined slides
taken through the dotted line C, D, (Fig. 2 and 3).
Fig. 5 is a transverse section of the inclined slides and part of the tramroad
as taken through the dotted line A, B, (Figs. 2 and 3).
The main body of the inclined slides, as clearly illustrated by Figs. 2, 3, 4,
and 5, can be constructed of wood, and faced with plates of some wear-resisting
material, such as iron or steel.
Fig. 6 shows a side view of the clip in elevation.
Fig. 7 shows a sectional elevation of the clip as taken through the dotted
line A, B, (Fig. 6).
Fig. 8 shows a front view of the clip.
The upper part of the clip or gripping coupling is formed like an ordinary hook;
and the lower part has a fixed jaw M and a loose jaw N moving on a pivot O.
Over the lower part of the clip is a shackle P which prevents the jaw opening
when the said shackle is in the position illustrated in the Drawings, that is, when
the shackle is at the extreme lower end of the clip, but when the said shackle is
raised above and clear of the moveable jaw the said moveable jaw can open.
lower ends of the fixed and moveable jaws are formed with a cavity or groove in
which the haulage rope J will rest, and in which it will be sccured when the
shackle is in the position illustrated in Figs. 6, 7, and S of Sheet 2 of the
Drawings; but when the shackle is raised above the moveable jaw the said rope
will be released from the clip.
The
In carrying this Invention into practice the clip coupling will be hooked on to
the corves G, G, G, and attached to the moveable rope J by raising the shackle P
of the clip and inserting in the cavities or grooves of the fixed and moveable jaw
the said rope 3, the shackle P will fall by its own weight and the corves will then

page_text: travel with and be hauled by the moving rope J. When the corves arrive at the
inclined slides K the rope and jaws of the clip coupling will travel through or
between the sides of the inclined slides, and the shackle P will travel over or along
the top of the said inclined slides, by which the said shackle P is raised above the
moveable jaw N, and the said clip coupling H and corves G, G, G, (Fig. 1) are
released from the said rope J.
When the clip coupling H arrives at the end of the inclined slides it will slide
up the tapered stop fixed between the pair of inclined slides, and the rope J will
pass underneath the said tapered stop, as shown in Figs. 2 and 3 on Sheet 1 of
the Drawings.
As a modification of the clip coupling (employed in combination with the inclined
slides) both jaws can be moveable and work on a pivot, as at O (Figs. 7 and 8),
the said clip coupling being in four principal parts instead of three as illustrated.
As a further modification the clip coupling can be constructed to work with a
chain, where a chain is used instead of a wire or other rope, as herein-described
and illustrated, the slides being of the same construction in either case.
The clip coupling and rope will be of iron, steel, or other materials usually
employed for those articles..
The haulage rope or chain will be of ordinary construction, and actuated and
guided in an ordinary manner.
Having thus particularly described and ascertained the object and nature of my
said Invention, and having shown in what manner it is to be or may be performed
and carried into effect, I claim as the essential features of the said Invention secured
to me by the herein-before in part recited Letters Patent, a clip coupling with a
moveable jaw or moveable jaws and shackle in combination with inclined slides
or guides, constructed and worked substantially as herein-before specified, described,
and illustrated in the accompanying two Sheets of Drawings, for the purpose of
hawling corves, tubs, trams, or other vehicles on trainroads, and automatically
detaching them from the haulage rope or chain at any desired point.
In witness whereof, I, the said James Pease, have hereunto set my hand and
seal, this Twentieth day of February, One thousand eight hundred and
seventy-nine.
