COMPLETE SPECIFICATION,
Improvements in and Apparatus for Removing Quarry "Barings."
I, WILLIAM WOOD, of Frankham Cottages, Fourstones, in the County of
Northumberland, Contractor, 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 refers to improvements in and apparatus for removing quarry
"barings."
According to the present system of removing the baring or earth or soil over-
lying the rock that it is intended to quarry, lines of tramway are laid down on
sleepers in various directions and small tubs or wagons are used into which the
baring is filled. By this system it is a difficult question to know where best to
deposit the baring. Not infrequently it is deposited at a distance back from the
quarry face, beyond where at the time it is intended to quarry the rock. In process
of time, however, it not infrequently happens that the quarry face advances to the
heap of tipped baring which has then to be loaded up and removed a second time.
By another system now in vogue in some cases gangways are constructed across
the quarry bottom and the baring is then filled into tubs or wagons and run across
the gangway to be deposited where the rock has been already excavated. By this
system the baring is got rid of without risk of the necessity above described for the
future removal thereof a second time but the cost of the gangways and their
construction render this system in most cases impracticable.
In both the above systems, moreover, the cost of tramways, sleepers, wagons and
leadage represents a very important item and the object of my invention is to
provide a means whereby the baring may be removed from the rock surface and
deposited in the most convenient position without the use of tramways and sleepers
or gangways.
I will now fully describe my invention having reference to the accompanying
drawings in which
Fig. 1 represents a section of a quarry with my improved apparatus in position
for removing the baring.
Figs. 2, 3, 4, 5 and 6 show details of construction more particularly hereinafter
referred to, and throughout this description like marks of reference in the
Specification and in the drawings represent like parts.
Referring to the drawings, let A A¹ represent the line of a quarry bottom. Then
A B C D is the rock to be quarried and CDE the baring being removed. Fis
an upright properly stayed in position fitted preferably with four pulleys 1, 2, 3, 4
(see Fig. 2 which is an end view of the upper part of upright F). H is also an
upright fitted preferably with three pulleys 5, 6, 7. 8 is the rail rope, 9 the traction
rope and 10 a guide rope. One end 9 of rope 9 is attached to one end of the
carriage 11 whence it passes round pulley 6 over pulley 2 to the winch friction
drum 12; being passed once or twice round this drum it returns over pulley 3 to the
other end of carriage 11 to which it is attached.
Rope 8 passes at either end over pulleys 1 and 5 and thence to an adjustable
ground attachment of suitable construction. This attachment should be made with
a lengthening screw or equivalent device so that the tautness of the rope can be
varied at will.
Rope 10 after passing under pulley 13 on carriage frame passes over pulleys 4
and 7 and thence to a ground attachment similar to that described in reference to
rope 8. The carriage 11 runs on a pulley 14 on rope 8, rope 10 acting as above
described as a guide for same. By turning the handle of winch 12 the carriage 11
is drawn backwards or forwards as desired. M are the kibbles into which the baring

page_text: is loaded fitted with bridles 15 and having hinged bottoms. The adjustment of the
bottom of the kibble may be made as shown in Fig. 4 which is a section of part of
a kibble bottom. In this figure L is a cranked lever a slot in one arm of which fits
over one end of the projecting bolt L' when the bottom is shut and locked. A
safety spring S2 may be let into the bolt L' arranged so as to sneck the lever L in
the vertical position but so as to offer no impediment to its being pulled over as
hereinafter described. To the other arm of the lever a line 16 is attached to the
end of which line the crosshead 17 (see Fig. 6) is connected for the purpose
hereinafter described.
The kibble bridle may be attached to the carriage 11 through the medium of a
lever 20 and bars 18, 18, 18". The bars 18" in this case are kept in various lengths
to suit the height between the carriage on the rail rope and the ground level and
are made so as to hook onto the bars 18 and 18 which are arranged with their flat
sides in the direction of travel of the kibble which thus tends to prevent the latter
oscillating during transit. The base of the bar 18" may be turned or bent up as
shown in Fig. 1 and between the cheeks thus formed, the curved lever 20 is mounted,
on the shorter arm of which the kibble is suspended the longer arm being brought
down and snecked or hooked to the side of the kibble at 21; when it is required to
detach the kibble, the sneck or hook aforesaid is released and the kibble can be
detached from the bar, the longer arm of 20 rising and the shorter arm dropping
for this purpose. Bar 18 may be permanently attached to the carriage frame 11 as
shown in Figs. 1 and 3.
The arrangement just described for attaching the kibble to the carriage may be
modified to suit circumstances but provision ought to be made to meet the varying
heights that will occur in practice between the rail rope and the ground.
The operation of my invention is thus as follows: The parts being erected in
suitable positions substantially as shown in Fig. 1 the baring is filled into the
kibbles when a kibble is full a bar 18" of suitable length is attached to bar 18 of
carriage 11 the bar 18" being then put in position the kibble bridle is slipped over
the short end of lever 20, the long end being locked as above described. A man
at the power winch 12 then runs the kibble out along the rope track over the quarry
face to the rubbish tip T where its contents are deposited by knocking off the catch
lever L. For obtaining an automatic "knock off" and for effectually depositing
the rubbish I may fix a pole or stake S in the ground in a suitable position with a
V-shaped catch strap S' at the end thereof projecting upwards somewhat and having
expanding arms or wings as shown in the plan Fig. 5. As the kibble comes along,
the crosshead 17 on end of line 16 suspended from the knocking-off lever becomes
engaged between the jaws of the catch strap S' and the kibble continuing its course,
the lever L is thus pulled over and the bottom of the kibble falls open. At this
moment the travel of the carriage is arrested, when the vis vivu of the kibble causes
its contents to be shot out well forward onto the spoil bank as shown in Fig. 1.
The winch 12 may either be a common hand windlass or a geared machine
actuated by hand, steam or other power as required.
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 :-
1. For removing quarry baring the improved arrangement of overhead rope
traction apparatus consisting of an overhead rail rope 8 whereon a carriage travels,
ropes 9 and 10, uprights F, H with their respective pulleys and winch 12 all
arranged and operating substantially in the manner and for the purposes
hereinbefore described and illustrated in the accompanying drawings.
2. In overhead rope traction apparatus for removing quarry baring the automatic
knock off arrangement for discharging the contents of the kibble consisting of the
catch-strap S¹, crosshead 17, line 16 and slip lever device L L on kibble the
several parts being arranged and operating substantially as and for the purposes
herein set forth.

page_text: 3. In the overhead rope traction apparatus for removing quarry baring described
and claimed in claim 1 the improved arrangement or combination of parts for the
attachment or detachment of the kibble to or from the carriage 11 consisting of
bars 18, 18, 18 and lever 20 arranged and operating substantially as and for the
purposes herein set forth.
4. The general arrangement or combination of parts constituting improved
apparatus for the removal of quarry baring substantially as herein described and
illustrated.
