PROVISIONAL SPECIFICATION.
An Improvement in Coke Oven Valves.
L, GEORGE WATSON MACALPINE of Altham near Accrington in the County of
Lancaster Colliery Proprietor do hereby declare the nature of this invention to be as
follows:-
•
My invention relates to a construction of valve for connecting to the hydraulic
main a coke oven from which gas is withdrawn to be treated, the objects which 1 have
in view being to effect a more tight closure of the connecting pipe, to lessen the
liability of the valve becoming choked by tar or other matter and to facilitate the
cleansing of the valve and seating or the removing and replacing of the valve box
without interfering with the operation of the hydraulic main and its branches.. On
the upper face of the hydraulic main I fix a flanged ring, on which the valve box is
bolted, this box being made with a tubular lower mouth which projects through the
flanged ring a little way into the hydraulic main and terminates in an internally
coned seating for the valve. The valve itself is in the form of a complete cone so that
matter which may be deposited on it readily slides off. It is attached to a rod which
extends up through a stuffing box in the lid of the valve box and terminates in a
cross handle. By this handle the valve can be drawn up nearly to its seat, but during
the last part of the ascent of the handle it is caused by a helical guide to turn partly
round, the valve being thus caused to close with a screwing movement which insures
tightness. At the side of the valve box, opposite that where the pipe from the oven
enters it, there is a cleansing door giving free access for cleansing the valve and
scating.

COMPLETE SPECIFICATION.
An Improvement in Coke Oven Valves.
1, GEORGE WATSON MACALPINE of Altham near Accrington in the County of
Lancaster Colliery Proprietor 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:-
My invention relates to a construction of valve for connecting to the hydraulic
main a coke oven from which gas is withdrawn to be treated, the objects which I
have in view being to effect a more tight closure of the connecting pipe, to lessen the
liability of the valve becoming choked by tar or other matter, and to facilitate the
cleansing of the valve and seating, or the removing and replacing of the valve box,
without interfering with the operation of the hydraulic main and its branches. The
accompanying drawing is a vertical section of the bydraulic main and valve according
to my invention, applied thereto. On the upper face of the hydraulic main A, I fix a
flanged ring B on which the valve box C is bolted, the lower mouth of which forms a
seating for the valve. The valve D itself is in the form of a complete cone so that
matter which may be deposited on it readily slides off. It is attached to a rod which
extends up through a stuffing box in the lid of the valve box and terminates in a cross
handle E. By this handle the valve can be drawn up to its seat, and can be turned
round so as to close when required with a screwing movement which ensures
tightness. At the side of the valve box opposite that where the pipe F from the
oven enters it there is a cleansing door G giving free access for cleansing the valve
and seating.

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 :-
F
The coke oven valve and valve box herein described with reference to the accom-
panying drawing.
