COMPLETE SPECIFICATION.
Improvements in or relating to Pulverizing and Mixing Cylinders.
I JOHN ROBERT ALSING of 53 Gracechurch Street in the City of London
Manufacturer, 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 that class of cylinders in which jars are used to hold
the material to be operated upon or where the cylinder itself acts as one jar and
this invention refers to the method of closing such jars or cylinders.
According to this invention round the neck of the jar or opening of cylinder I
fix a metal band having two arms sufficiently long to project over top of jar or
opening and in each of said arms I have a hole so that the ends of a bar may take
therein and the centre of bar is provided with a screw so that when this latter is.
screwed against the cover it is firmly secured.
And in order that my said invention may be fully understood I will describe the
same with reference to the accompanying sheet of drawings in which :-
Fig. 1. shews elevation of pulverizing cylinder fitted with my improvements
adapted thereto.
Fig. 3. shews a jar used in cylinder for pulverizing as in a former invention for
which I obtained Letters Patent dated the 27th day of April 1886, No. 5734.
Fig. 2. shews detail hereafter referred to.
The same letters denote the same parts in all the views.
a. shews pulverizing cylinder or jar, b shews cover of same secured by means of
metal band c. which surrounds the neck of opening the two ends of such band being
secured by screw and nut g.
The said band has two eyes d. or arms with holes therein so that the ends of the
cross bar e. may enter such eyes or holes f. is a screw screwed through centre of
cross bar e. The band c. is shewn detached at Fig. 2.
In order to secure the cover of jar or cylinder it is simply necessary to drop.
cover on and pass ends of bar e through the eyes d then screw down the screw f.
by which action the cover will be firmly secured.
