PROVISIONAL SPECIFICATION.
Improved Construction of Links for Travelling or Carrying Belts.
I, WILLIAM HENRY BARKER, Engineering and Mining-Tool Works, Market
Street, Fenton, Stoke-on-Trent, Staffordshire, Engineer, do hereby declare the
nature of this invention to be as follows:-
This my invention has reference to an improved construction of links for use
in the construction of carrying or travelling-belts for carrying or elevating various
materials in mines, collieries or other places, the object of my said invention being
to simplify the construction of such links, and to obviate the rivetting of metallic
tabs or angle pieces thereto as is usually done in the construction of such links.
One way of carrying my said invention into practice is by taking a piece of
angle-shaped wrought-iron, wrought-steel or the like suitable metal of suitable
size and thickness according to the size of link required, after making such length
of metal sufficiently hot I cut or make two transverse slits in one arm of such
piece of metal at a suitable distance apart by using a circular saw of suitable
thickness, or by other suitable means, I then press or double over the outer lengths
or ends of such slitted arm against the other or unslit arm by using a press, steam-
hammer, sledge-hammer or like suitable means and so strengthen the ends of such
links, before or after drilling a hole of suitable size through each end of double
thickness of such links, and any suitable number of holes in required position
through the tab, or projecting portion of such links, the corners of each link,
and of the tabs if desirable may be rounded by filing, cutting, sawing or chipping,
or any two or more of such operations.
Two of such links placed back to back may be used to form intermediate links
for such carrying or travelling-belts; but I prefer to make intermediate links for
such carrying-chains or carrying-belts from T shaped wrought-iron or wrought-
steel, by making two transverse slits in each arm of such lengths of metal at a
suitable distance apart by using a metallic circular saw or other suitable means
after first sufficiently heating such metal-links, or whilst in a cold state, the outer
ends or lengths of each arm being bent or doubled over by using a press, hammer
or like suitable means so that each end of such links will be of threefold thickness,
each end so formed may be made hot in a suitable fire and the three thicknesses
of metal welded or consolidated to one thickness by means of a steam-hammer,
hydraulic-press or the like, holes of suitable size and in suitable position being
drilled or punched through the tabs, and through such links near to their outer
ends, the corners of such intermediate links and their tabs being removed or
rounded by chipping, filing or other means.
Intermediate links may be formed for use with such travelling-chains or carry-
ing belts from steel or iron having a -shaped cross-section, the tabs being
formed on each of their sides by making two slits in each of their sides at a suitable
distance apart by using a circular saw or like means, and afterwards bending the
portion between such slits at right-angles or nearly at right-angles to their depend-
ing portion.

page_text: In a modification of the foregoing I stamp blanks of suitable shape and size
from wrought-iron or wrought-steel plates of suitable thickness by means of a
'suitable metallic die or dies attached to a suitable press or machine, the requisite
holes in such links and their projecting tabs being punched during the process
of stamping, or drilled or punched after such blanks have been bent into shape
to form links.
Improved Construction of Links for Travelling or Carrying Belts.
I, WILLIAM HENRY BARKER, Engineering and Mining-Tool Works, Market
Street, Fenton, Stoke-on-Trent, Staffordshire, 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: -
This my invention has reference to an improved construction of links for use
in the making or formation of carrying or travelling belts for elevating or carry-
ing various materials in mines, collieries, and other places, the object of my said
invention being to simplify the construction of such links and to obviate the
rivetting on of metallic tabs or angle pieces as is usually done in the construction
of such links.
In making such improved links I take a piece of angle shaped wrought-iron,
wrought-steel, or like suitable metal of suitable size and thickness, according to
the length or size of link required and after sufficiently heating such lengths of
metal I cut or make two transverse slits or cuts in or through one arm or side
of such angle iron or steel lengths at a suitable distance apart by using a metallic
circular saw of suitable size and thickness, or by other like suitable means, I then
press or double over the outer lengths or ends of such slitted arm against the
other or unslit arm by means of a screw-press, hydraulic-press, steam-hammer,
sledge-hammer or like suitable means, which double thickness at each end of
such links will increase the strength of such links before or after drilling a hole
of suitable size through each end of double thickness, and any suitable number
of holes in desired positions through the tab or projecting portion of such
links.
Two of such links placed back to back may be used to form intermediate links
for such carrying or travelling belts; but I prefer to make intermediate links
for such carrying chains or belts from T shaped wrought-iron or wrought, or cast
malleable steel by making two transverse slits by using a metallic circular saw
or like suitable means at a suitable distance apart in each opposite arm of such
lengths or links of iron or steel after having first sufficiently heated such metallic
lengths, the outer ends or lengths of each slitted arm being bent or doubled over
by using a suitable press, hammer or the like means so that each end of such links
will be of three-fold thickness, each end so formed may if desired be suitably
heated and the three thicknesses of metal at each end welded or consolidated to
one thickness by means of a steam hammer, a hydraulic press or other suitable
means.
Intermediate links for such travelling-chains or carrying-belts may be made
from wrought-iron, or wrought or cast malleable steel having an cross-section,
a tab being formed on or at each of their sides by making two slits therein at a
suitable distance apart by using a metallic circular saw or like suitable means
and afterwards bending the portion between such slits at right angles or at about

page_text: right angles to their remaining or other portion, a hole or holes of suitable size
being drilled or formed in desired positions after bending. The corners of each
link made as described and of their tab or tabs may if desired be rounded by
filing, sawing, chipping or other suitable means.
In a modification of the foregoing I stamp blanks of suitable shape and size
according to the size and shape of the links required from wrought-iron or wrought
steel plate of suitable thickness by means of a steel die or dies attached or fixed
to any suitable press or machine, the required holes in such links or blanks being
punched during the process of stamping or drilled or punched after such blanks
have been bent by any suitable means to form links.
In order that my said invention may be more readily understood and explained
in detail I have hereunto annexed a sheet of drawings on which letters of refer-
ence are marked on corresponding parts on all the figures alike.
DESCRIPTION OF DRAWINGS.
Figures 1 and 7 are side elevations of links made from angle and channel iron
or steel according to my invention, two of either of which links when placed back
to back may be used as intermediate links for such chains or belts.
Figure 4 is a side elevation of an intermediate link made according to my
invention from wrought T iron or steel which I preferably use in the construction
of such carrying belts or chains.
Figures 2, 5 and 8 are plan views of the links shewn at Figures 1, 4 and 7.
Figures 3, 6 and 9 are end views of the links shewn in the above figures.
Figure 10 is a plan view showing how such links are fitted together for form-
ing such carrying chains or belts.
Figure 11 is a side elevation or view of Figure 10.
Figure 12 is a plan view of a sheet steel or wrought-iron blank, the ends or
corners of which may be left square, rounded off, filed off or machined off by any
suitable means as shewn by dotted lines.
Figure 13 is an end view of a link formed from the blank shewn at Figure 12,
and
Figure 14 is an end view of two of the metallic links shewn at Figure 13 placed
back to back to form an intermediate link.
In these figures a and b represent wrought-iron or steel links made according
to my invention from angle and channel iron or steel connected to an inter-
mediate link c made from wrought iron or steel by means of wrought-iron or
steel bolts d.
The tabs e of such links being at right angles or at about right angles to their
depending or lower portion f against which the ends 9 are firmly pressed or
hammered.
On reference to Figures 12, 13 and 14 I would have it understood that the bolt
or pin-holes may be punched during the process of stamping such blanks, be drilled
through such blanks after stamping, or after such blanks have been bent along
the dotted line h so that the tab e and part f will be at right angles, or at about
right angles to each other as shewn at Figures 13 and 14 in end view. Friction
chains of any suitable length may be made from or with such links by curving
such links whilst in a heated condition before being connected by any suitable
means to suit the periphery of the pullies, riggers or drums around which such
chains are desired to run or travel.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
-
1st. The method or manner of constructing links of any suitable size, or of
various or different sizes for carrying or travelling belts for use in mines, collieries
and other places of or from angle, channel, T shaped and shaped wrought-
iron, wrought-steel or cast malleable steel lengths or bars in the manner herein
substantially described set forth and shewn on the drawings hereto annexed.

page_text: 2nd. The method or manner of constructing links of any suitable size, or of
various or different sizes for carrying or travelling belts for use in mines, collieries
and other places of or from blanks pressed or stamped from wrought-iron or
wrought steel plates of suitable thickness or thicknesses and pressing or bend-
ing such metallic blanks into links of the required shape and size as herein sub-
stantially described set forth and shewn on the drawings hereto annexed.
