Improved Neck Box and Adjustable Brasses for Edge Runner Mills.
CHARLES JAMES WILLIAMS 86 Annandale Road East Greenwich in the County
of Kent Engineer and JABEZ HOLLICK 3 Coleraine Road Blackheath in the
County of Kent Cement Manufacturer do hereby declare the nature of this
invention to be as follows:-
Our invention relates to edge runner mills particularly to those patented by
John George Freeman Number 5950 in the year 1890 and consists of an improved
neck box grooved to receive adjustable brasses with spaces between for lubricants
and fitted with step wedge for tightening brasses round spindle. The defect in the
above named mills or one of them consists in the impossibility of keeping the rollers
in their proper circle when the brass neck bush becomes worn and an advantage of
our invention is that it will then be easy to wedge the neck brasses as they wear
and thus keep the rollers in their proper path without having to change neck
brass.

Improved Neck Box and Adjustable Brasses for Edge Runner Mills.
We, CHARLES JAMES WILLIAMS 86, Annandale Road, East Greenwich in the
County of Kent, Engineer, and JABEZ HOLLICK 3 Coleraine Road Blackheath
in the County of Kent, Cement 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 refers to neck boxes and consists of a method of tightening up the
slack caused by wear in the contact of the guiding brasses of the said neck boxes
of the vertical shafts of edge runner mills, and particularly to such mills as that
patented by John George Freeman No. 5950 of 1890.
This is effected by using two or more projecting metal strips or liners arranged
to suit the size of the shaft or spindle. They are fitted in grooves formed in the
body or case of the neck box, and behind one or more of such grooves, we introduce
a wedge fitted with a screw and nut and cover plate at one end, so that the wedge
can be drawn further in, and thus press forward the strip when worn.
This wedge is of peculiar step-like form, and resembles several wedges joined
together endways.

page_text: We will now describe the invention with reference to the accompanying drawings
in which :-
Fig. 1 shows a partial sectional elevation of a bearing for a vertical shaft,
provided with our improved wedge fitting for taking up the wear upon the inner
bearing strips of suitable metal.
Fig. 1 shows an enlarged side elevation of the wedge screw bracket e¹ and
method of connecting screw e to wedge d.
Fig. 2 shows a plan view of Fig. 1.
Fig. 3 shows a plan view of the underside of Fig. 1.
a is the shaft, and b is the body or case of the bearing; c, c, are bearing strips of
brass, or suitable metal, which form contact with shaft a; d is a stepped wedge
placed behind one of the strips c. The wedge d. is connected to a bolt e, having
nuts e, and bracket at its lower end, for adjusting the wedge, and taking
up the wear on the bearing strips c, c, f is a cover-plate at the lower side of the
bearings.
It may become necessary when the two strips, opposite to the one provided with
the wedge, are much worn, to pack them bebind with packing strips to force them
out against the shaft. Each of the strips can thus be worn out entirely, thus
effecting a great economy in repairs of shaft bearings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In a bearing or guide block for vertical shafts or spindles, of edge runner mills
and for like purposes the improved neck box consisting of the body b, lining
strips c, c, and stepped wedge d, fitted with screwed bolt and nut e, e, bracket and
cover plate f, as herein described and set forth.
