COMPLETE SPECIFICATION.
Improved Means and Apparatus for Charging Gas Purifiers with
Lime, or other Purifying Agent, from the Cover Lifting Machine
or Overhead Traveller.
I, HENRY GARDNER, of 166 Fleet Street, City of London, Patent Agent, do
hereby declare the nature of this invention which has been communicated to me
from abroad by Frederic Deacon Marshall, of The Danish Gas Company Limited,.
of Copenhagen, Denmark, and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention has for object the utilization of the overhead travelling crane or
goliath employed in lifting and replacing the covers of purifiers in gas works to the
carriage of skeps or buckets for supplying such purifiers with lime or other
purifying agent, also to fitting additional lines of rails in a gas purifying shed for
the easy movement of such skeps or buckets when loaded whether for charging the
purifiers, or for the removal of the spent lime therefrom.
One or more of the rails is or are attached to and suspended from the frame of
the overhead traveller and so shaped that the skeps or buckets can be led over any
desired part of any of the purifiers, said rails being provided with switch points
for the proper divergence to or from the additional rails in the building, which also
have switch points adjustable by hand for directing each skep or bucket to the
desired spot at any part of the shed, or over any one purifier in said shed.
In some cases such as when a loft is above the purifying shed other rails can be
arranged therein as a ready means for storing the skeps or buckets, or for trans-
porting the skeps or buckets from the lime heap to a cage, into which each skep
can be pushed and then be lowered on to the fixed lower rail for movement to the
additional rail suspended from the traveller.
The invention will be more particularly understood by reference to the annexed
drawings in which Figure 1 represents a part longitudinal section of a purifier shed
of a gas works. Figure 2 an open end elevation, and Figure 3 a plan.
A, A, are the purifiers, B the overhead traveller or goliath. C, C, are bars
hanging therefrom with stays or ties D, D. E is a rail curved or half rounded at
one end and suspended from the bars C, C. F, F, are switch points for leading
the skeps G from the main rail H to any position over the purifiers A, A, above
which the traveller B might be shifted.
The rail E is spanned clear of the traveller chains so as not to interfere with any
motion or mechanism by which the purifier covers can be lifted or replaced. Each
skep G or bucket is suspended to swivel and turn for tipping purposes within a fork
frame I, the upper end of which is provided with flanged wheels J to run freely
upon the rail H on which it can be moved.
In the drawings a couple of rails K, K, are shown in the upper floor of the shed
along either of which rails the skep G can be pushed after action of the switch
point L, so that when the cage M is raised to the proper level and the skep G rua
on or into it, the cage M can be lowered for the skep G to be transferred to the
rail H of the lower chamber of the shed, for being shifted to the curved rail E
suspended from the overhead traveller B for the contents of the skep to be emptied
into the open purifier A, the lid of which had been previously removed.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The fixing and employment of additional rails with switch points in a gas
purifying shed or frame surrounding a set of gas purifiers to facilitate the movement
of skeps or buckets in, alongside of, or over the gas purifiers as and for the purposes
described.
2. In connection with overhead travelling cranes by which gas purifier covers
can be lifted, a frame with switch rail attached and suspended therefrom for
reception or support of moveable skeps or buckets for the conveyance of lime, or
other purifying agent thereto, or therefrom, substantially as shown and as described.
