Improvements in Devices for Removing Pitch from Tuns or Casks,
I, CARL FRIEDRICH FRANZ KÖPPING, of 141, Bernsdorferstrasse, Chemnitz,
Germany, 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 the construction of nozzles or tuyeres for removing
pitch from tuns or casks, and more particularly to the arrangement of the suction
pipe in machines employed for this purpose.
The invention consists in the construction, novel combination and arrangement
of parts, fully described hereinafter and specifically pointed out in the appended
claims.
In the accompanying drawings:-
Fig. 1 is a vertical longitudinal view of the improved construction.
Fig. 2 is a top plan view of same.
Similar letters refer to similar parts throughout. both views.
Referring to the drawings, A represents a vertically arranged, cylindrical coke-
stove of usual construction, and provided at its upper part with a cylindrical
nozzle a suitably secured in the wall of the stove. On this nozzle is adapted
to rotate an elbowed arm b, suitably held on said nozzle, (for instance by means
of pins or the like engaging a circular groove on the nozzle), and carrying the
pipe. Upon the latter is arranged the perforated socket & having its free end
turned downwards and extending into the tun or cask and adapted to rotate
and move on said pipe. e is a suction-head adapted to rotate on c and rigidly
connected with the downwardly extending pipe f. extending movably into the
revoluble elbowed pipe g adapted to rotate on the stationary pipe h leading to the
smoke-conduit. ¹, k, represent a double or combined carriage, adapted to move
in two directions and permitting of the easy manipulation of tuns or casks. 7 is
a worm-gear wheel keyed upon the revoluble elbow and meshing with a screw m.
n is a hand-wheel on said screw for actuating the same.
The operation of the improved construction is as follows:-
-
The tun or cask is rolled upon the carriage i, k, so that the usual door
thereof is at the top, and that the bung-hole is at the bottom (see dotted line
position). Then the movable elbowed arm is brought in a position by means
of the hand-wheel actuating the screw m and the worm-wheel 7, so that the
pipe c and the socket are on a level with the door of the tun or cask. Now
the carriage together with the tun or cask are moved laterally on the carriage i
until the door is brought in front of the socket d. whereupon the carriage i together
with the tun or cask are moved forwards until the front-wall of the latter engages
the suction-head e (see full line position). Now the pipe e and socket d extend
into the tun or cask whilst the door of the latter is closed by means of the suction-
head e
The combustion gases coming from the coke store A. pass through the
nozzle a. the elbow 6, the pipe cand the socket 7 into the tun or cask, and

page_text: produce the melting of the old pitch, and as the bung-hole of any tun or cask
is always at the bottom, the melted pitch flows readily out from the tun or cask.
The smoke produced in the operation is drawn through the door, the suction-
head e, and the pipes f, g, h, into the chimney.
The suction-head e and the pipes f and are moved or displaced automatically
as follows: When the elbowed arm is rotated on the nozzle a by means of the
hand-wheel the screw m and worm-wheel 7, the suction head e and the pipe f
are operated by the pipes b, c, whilst the pipe f moves up and down within the
elbowed pipe g, whereby the latter is rocked on the stationary pipe h.
It will be readily understood that the pipe e and the suction-pipe may be
easily adjusted by means of the hand-wheel », in accordance with tuns or casks
of any size, which is not possible in any of the devices heretofore constructed
for the same purpose.
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:
1) In an apparatus for removing pitch from tuns or casks of any size, the
combination with the usual coke-stoke, and a stationary nozzle on said stove, of
an elbowed-pipe, revolubly mounted on said nozzle, a tubular extension on
said elbowed pipe adapted to extend into the tuns or casks, means for drawing
smoke from the latter. means for readily manipulating the tuns or casks and
means for actuating said revoluble elbowed-pipe, substantially as described and
set forth.
2) In an apparatus for removing pitch from tuns or casks of any size, the
combination with the usual coke-stove and a stationary nozzle secured in the
wall of said stove, of an elbowed pipe, revolubly mounted on said nozzle, a suitable
extension on said pipe adapted to extend into the tuns or casks, a suction-head or
box open at one end and revolubly mounted on said extension a depending pipe,
rigidly secured to said suction-head, and telescoping into another elbowed pipe.
a stationary conduit communicating with the chimney, and receiving the end of
said elbowed pipe, means for readily actuating the movable parts of the con-
struction. and means for easily moving tuns or casks to and away from the
suction-head, substantially as described and set forth.
3) The combination with the revolubly mounted elbowed pipe, the suction-
head, and telescoping pipes, of a worm-wheel keyed upon said elbowed pipe, a
scrow meshing with said worm-wheel, and a hand-wheel on said screw, sub-
stantially as and for the purpose set forth.
4) The improved apparatus for removing pitch from tuns or casks of any
size constructed and arranged substantially as described and shown.
