IMPROVEMENT IN ROPE CARRYING GEAR AND SUSPENDED TRAMWAYS
Year: 1884

page_text: I, OLIVER IMRAY of N° 28 Southampton Buildings, Chancery Lane in the
County of Middlesex, Patent Agent do hereby declare the nature of the said
invention for AN IMPROVEMENT IN ROPE CARRYING GEAR AND SUSPENDED
TRAMWAYS to be as follows:
For conveying loads from place to place there are often employed an arrangement
of rope carrying gear and of suspended tramways. In the one case a rope is made
to travel over guide pullies and the load suspended from it is carried along with
the rope. In the other case the rope is stationary and a truck or carriage from
which the load is suspended is made to run along the rope. In the former case,
the connections by which the load is suspended from the rope are necessarily bent
or indirect in order to clear the guide pullies over which the rope runs. In the
latter case the connections by which the rope is suspended have likewise to be bent
or indirect in order to clear the wheels of the truck which runs along the rope.
This invention relates to a construction of the guide pullies and truck wheels
employed in apparatus of the kind referred to, whereby the suspending connections
are made direct and simple, giving great facility for attaching and detaching the
loads that are conveyed. For this purpose, the pullies or wheels are made in two
parts each having the shape of a frustum of a conc. These are nounted on
separate axes in the same line with their smaller faces presented towards each
other a sufficient space being left between those faces for the passage of the
suspending connection. Thus when the rope travels it runs in the V shaped groove
presented by the two conical surfaces of the duplex guide pulley, and the direct
suspender of the load passes through the space left between the two half pullies.
Or when the rope is stationary, the duplex wheels of the truck that runs along it
present a V shaped groove embracing the rope, and between the two half wheels
there is space for passing clear of the direct suspenders of the rope. Instead of
ropes, chains may be used, the pullies or wheels in that case having peripheries
indented to suit the chain links.

I, OLIVER IMRAY of No: 28 Southampton Buildings, Chancery Lane in the
county of Middlesex Patent Agent, do hereby declare the nature of the said
invention for AN IMPROVEMENT IN ROPE CARRYING GEAR AND SUSPENDED
TRAMWAYS and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement.
"
For conveying loads from place to place there are often employed arrangements
of rope carrying gear and of suspended tramways. In the one case, a rope is made
to travel over guide pulleys and the load suspended from it is carried along with
the rope.
In the other case, the rope is stationary and a truck or carriage from
which the load is suspended is made to run along the rope. In the former case,
the connections by which the load is suspended from the rope are necessarily
bent or indirect in order to clear the guide pulleys over which the rope runs. In
the latter case the connections by which the rope is suspended have likewise to be
bent or indirect, in order to clear the wheels of the truck which runs along
the rope.
This invention relates to a construction of the guide pulleys and truck wheels
employed in apparatus of the kind referred to, whereby the suspending connections
are made direct and simple, giving great facility for attaching and detaching the
loads that are conveyed. For this purpose the pulleys or wheels are made in two
parts each, when applied to a rope, having the shape of a frustum of a cone. These
are mounted on separate axes in the same line, with their smaller faces presented
towards each other, a sufficient space being left between those faces for the passage
of the suspending connection. Thus, when the rope travels, it runs in the
V-shaped groove presented by the two conical surfaces of the duplex guide pulley,
and the direct suspender of the load passes through the space left between the two
half pulleys. Or, when the rope is stationary the duplex wheels of the truck that
runs along it present a V-shaped groove embracing the rope, and, between the two
half wheels, there is space for passing clear of the direct suspenders of the rope.
Instead of ropes, chains may be used and the pullies or wheels in that case may
have peripheries indented to suit the chain links.
Fig. 1 of the accompanying drawings shews the arrangement, according to my
invention, when the rope carrying the weight runs over the pullies.
Fig. 2 shews the arrangement when the pulleys are mounted on a truck that runs
along a suspended rope.
Fig. 3 shews a like arrangement when a suspended T-iron bar is used instead of
a rope, in which case the wheels have flat faces.
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
For rope carrying gear or suspended tramways, the use of pulleys or wheels,
made in halves, and mounted with a space between the halves for passage of direct
suspenders, substantially as herein described.
