Improvements in Apparatus to be Used in Connection with Hauling
by Means of an Overhead Chain or Cable.
I, CHRISTIAN ALBERT JENSEN of 77 Chancery Lane in the County of London
Patent Agent do hereby declare the nature of this invention a communication to me
from abroad by Messieurs Schüchtermann & Kremer of Dortmund in the Empire of
Germany Engineers and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention refers to apparatus to be used for hauling trucks or other vehicles
either under or above ground by means of a chain or cable, and in order that it
may be more easily understood reference is made to the accompanying drawings
of which
Figure 1 illustrates a bracket in end view and partly in section for carrying and
guiding the chain or cable along a straight part of the track.
Figure 2 is a plan thereof partly in section.
Figure 3 is detail view in side elevation.
Figure 4 is a side elevation of the bracket with a part thereof removed.
Figure 5 is an end elevation partly in section of a bracket for carrying and guiding
the chain or cable round a bend or curve in the track.
Figure 6 represents a tunnel in longitudinal section with this invention applied
thereto and
Figure 7 is a plan of same showing two sets of rails with the truck removed.
Referring to Figures 1, 2, 3, 4 and 6 it will be seen that the hauling chain or
cable A is normally supported on loose pullies or wheels b which are mounted on
studs B. The studs are bolted or otherwise fixed into the bracket which is preferably
made in two parts fand g as shown, the latter being secured rigidly together by a
bolt h, and by reason of a projecting part of the side g taking into a corresponding
recess in the other bracket part f. It will however be understood that by a slight
modification the bracket might for instance be made in one piece and be provided
with a slot or slots instead of holes for the studs B. The bracket is bolted or clamped
to a girder or other suitable support i. a represents the gripper which may also be
of any other convenient construction and which is fixed or mounted in a socket a¹
Figure 6 on the truck or other vehicle. When the gripper a counes to the bracket
it is guided by means of the curved guides c of T or other suitable section and the
chain A is momentarily lifted off the wheels B while the gripper is passing
between them.
Figures 5, 6 and 7 show the arrangement for guiding the chain or cable round
curves and in this case the curved guides c may be dispensed with providing the pullies
or rollers e be of a sufficiently large diameter.
These rollers e have grooves el which serve as guides to the chain or cable A except
when the gripper a is passing between them. One of the rollers e serves as a guide
whilst the other one serves to keep the chain from slipping down when the gripper
is not passing in between them. The roller e which only serves as a guide to the
gripper a and to keep the cable or chain from falling down may under some circum-
stances be replaced by a guide similar to c (Figures 2, 3 and 4) if the latter be placed
close enough to prevent the chain from falling down the opening for the entry of the
gripper. The bracket k may conveniently be made in one casting and is as before
described with reference to figure 1 bolted or clamped to the girder or support i.
Although the invention has only been shown in Figures 6 and 7 as applied to
underground. haulage it is evident that it might under some circumstances be applied
with equal advantage above ground.

page_text: Having now particularly described and ascertained
of the said
invention and in what manner the same is to be performed I declare that what
I claim is,
First. In a system for hauling trucks or other vehicles by means of cable or
chain A the gripper a on the truck the brackets gf with guides cand pullies or
rollers for the straight parts of the track and the brackets & with rollers or pullies e
for the curves or bends of the track substantially as described and shown.
Second. In a system for hauling trucks or other vehicles by means of cable or
chain the guides c and pullies or rollers & held in suitable brackets all so arranged
as to allow the gripper to pass between them substantially as described and shown.
Third. In a system for hauling trucks or other vehicles by means of cable or chain
the improved construction of bracket k with rollers or pullies e substantially as
described and shown.
Fourth. The improved constructions of parts as shown on the drawings.
August 1889.
