Improvements in Belts for Haulage and the Transmission of Power.
I, JACOB HEINRICH BEK, of Stockach, in the Grand Duchy of Baden, German
Empire, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a belt, designed to supersede the ordinary wire ropes, used
for haulage in mines, etc., and also the belts and ropes of leather, hemp, cotton, or
the like, used for the transmission of power.
A belt made according to my invention consists of a number of separate square
plaited ropes placed beside one another, which are sewn together by wire laces, or
attached together by pins in the manner of link or chain belts.
The single square plaited ropes are preferably made of wire, if intended for
haulage or of hemp or other fibrous material, if intended to be used for the
transmission of power.
The described belts have the advantage of greater flexibility over the ordinary
belts twisted ropes etc., even where considerable power has to be transmitted, and
where therefore the dimensions are large to give sufficient strength.
These belts are particularly advantageous when used as endless belts for power
transmission. For this purpose the several square plaited ropes are laced together
and the joints are alternated to one another and equally distributed over the whole
length of the belt. The belts are therefore of like thickness and strength at all
parts, in consequence they run very evenly and flapping is avoided at all parts.
Further the loss of power caused by stiffness of the means of transmission is
very small with these belts.

Improvements in Belts for Haulage and the Transmission of Power.
I, JACOB HEINRICH BEK, of Stockach, in the Duchy of Baden, German Empire,
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 invention relates to a belt designed to supersede the ordinary wire ropes
and similar devices used for haulage or traction and also the belts and ropes of
leather, hemp cotton or the like used for the transmission of power, for which
purpose this belt is especially advantageous.
This invention consists of a belt made of square, plaited ropes, placed beside one
another and connected together by stitches, pins or wire.

page_text: In order that this invention may be the better understood, I now proceed to
describe the same, reference being had to the accompanying drawings and to the
letters and figures marked thereon.
Like letters refer to like parts in the various figures.
Figure 1 is a view of a belt, in which the several ropes are sewn together by
rows of stitches.
Figure 2 is a sectional view of the belt.
Figure 3 is a view of a belt in which the several ropes are connected to one
another by wire pins, transversely disposed.
Figures 4 and 5 illustrate the arrangement of the splicing, and
Figure 6 is a sectional view of an exceptionally wide belt, built up of a number
of narrower belts connected together by cramps.
a
a are the several ropes, placed beside one another, of square cross-section,
see Figure 2, and plaited from strands of wire, hemp, cotton, strips of leather or
similar material. These ropes are connected together by wire or strips of leather b;
or pins c may be used which are pushed through the ropes sideways, their ends
being then bent and pressed in the form of hooks into the ropes which form the
edges of the belt. See Figure 3.
If these improved belts are to be used for the transmission of power it is
necessary, to connect together lengths of ropes, of which the belt is made, by
splicing. The spliced parts of the several ropes may be placed so as to break
joint near each other, or at positions some distance apart from one another, so that
the splices are distributed over the whole length of the belt. When the belt is
made of a comparatively large number of ropes it is not necessary to splice all
the ropes, in such case a number of the elementary lengths of the ropes may butt
against one another. The connecting stitches or pins e are then preferably
arranged close together near the butting joints.
When belts are required of such a width that the stitches or pins c cannot
conveniently be drawn or pushed through the whole width of the belts, constructed
as above they are connected together by cramps d, Figure 6, which are pressed
from below, through the edges of the elementary belts d, Figure 6, and are
hammered over on the upper face in the form of hooks.
If
Belts of ropes thus constructed are very flexible compared with belts of leather
or other material as used hitherto. The loss of power caused by stiffness of
belting is therefore very low. Further, such belts possess great durability.
the splicing of the various lengths of rope is well done, the belts are of even
section along the whole length of belt, which therefore runs very quietly. Another
advantage of these belts is that they do not slip because their adhesion on the
pulleys is great and may be increased by the application of suitable material, which
enters into the fibres of the ropes and fills all the pores, so that a great surface
of belting is in contact with the faces of the pulleys.
In order to obtain equal tension in the several ropes of the whole belt, the
several ropes may be of uneven length according to requirement.
Belts have been described, previous to my invention of round twisted ropes, but
they have not come into use, because they have many great disadvantages, which
are want of adhesion to the pulleys, caused by insufficient contact with the faces
of the latter; considerable stiffness, by which, their adaptation to the peripheries
of the pulleys causes considerable loss of power; and the difficulty of connecting
the several round ropes, so as to form a strong belt. Further, as soon as one
rope projects over the neighbouring ropes, the side pressure from the latter quickly
forces the other rope completely out of position.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that I do not claim
belts made of round ropes, but what I claim is :-
1st. A belt for haulage, traction or the transmission of power consisting of
square plaited ropes a placed beside one another and connected together by wire,

page_text: wire or leather laces b or by pins c pushed through the ropes and bent at the
ends in the form of hooks, substantially as described.
2nd. The form of construction of a belt of square plaited ropes, claimed in
Claim 1, consisting of several such belts, connected together at their edges by
cramps d driven through the edges, for the purpose of constructing a belt of
considerable width, substantially as described.
