We GEORGE HARRISON Manager and THE NORTHERN ENGINEERING COMPANY
Limited of Hopwood Lane, Halifax in the county of York, Engineers and Machine Tool
Makers 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:
For boring pedestals, we employ an ordinary lathe the loose headstock having a
quick and slow motion to facilitate the changing of the pedestals, to the travelling slide
is attached a ball, upon the ball is pivotted by means of cups, a plate or bed upon
which are mounted the pedestals to be bored, the pedestals are secured by bolts, in a
slot traversing the length of the plate or bed. In the travelling slide are tapped two
holes into which are screwed the bosses of two adjustable hand nuts, a bolt passes
through each nut, and secures the plate in position, this position being adjustable to
any height or angle (by means of the cup and ball joint) to suit any size of
pedestal.
The pedestal is then passed to a rimering apparatus of similar construction, then to
a second lathe head, on the spindle of which is placed an adjustable tool holder carrying
the required tool or cutters for surfacing and finishing; to this lathe head is attached
a short bed upon which is a slide, on the slide is a turret, in which is a holder to carry
shafts of the various template sizes required; the turret can be moved from or towards
the tools by means of a hand lever or hand wheel and screw, and locked by a
suitable nut.
The pedestal to be finished, is placed upon the template, mandril, and the slide is
moved up to the cutters, by the hand wheel and screw, or by the hand lever, and
after one side of the pedestal is finished, the turret is reversed by hand, and the
other side is then surfaced and finished; the turret is held in position by a spring
catch.
A drilling apparatus is attached to the finishing head which drills the grease holes
in the pedestals whilst upon the finishing apparatus.

We GEORGE HARRISON Manager and THE NORTHERN ENGINEERING COMPANY
Limited all of Hopwood Lane, Halifax in the county of York, Engineers and Machine
Tool Makers, 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 :-
For boring pedestals we employ an ordinary lathe, the loose headstock having a quick
and slow motion, to facilitate the changing of the pedestals; to the travelling slide is
attached a ball, upon the ball is pivotted, by means of cups, a plate or bed, upon which
are mounted the pedestals to be bored, the pedestals are secured by bolts in a slot
traversing the length of the plate or bed.
In the travelling slide are tapped two holes, into which are screwed the bosses of
two adjustable hand nuts, a bolt passes through each nut and secures the plate in
position, this position being adjustable to any height or angle (by means of the cup
and ball joint) to suit any size of pedestals.
The pedestals are then passed to a rimering apparatus of similar construction, then
to a second lathe head, on the spindle of which is placed an adjustable tool holder,
carrying the required tools or cutters for surfacing and finishing.
To this lathe head is attached a short bed upon which is a slide, on the slide is a
turret, in which is a hold to carry shafts of the various template sizes required, the
turret can be moved from or towards the tools by means of a hand lever, or hand wheel
and screw, and locked by a suitable nut.
The pedestal to be finished is placed upon the template mandrill, and the slide is
moved up to the cutters by the hand wheel and screw, or by the hand lever; and after
one side of the pedestal is finished, the turret is partially reversed by hand, so as to
allow the pedestal to be reversed the other side is then surfaced, and the turret being
held in position by a spring catch.
A drilling apparatus is attached to the finishing head which drills the
in the pedestals, whilst upon the finishing apparatus.
grease holes

page_text: and J the worm wheel, E. F. G are gear wheels for operating (by means of the
rack H) the travelling slide D; to the travelling slide D is attached a ball K ; upon
the ball is pivotted by means of cups L, a plate or bed M, upon which are mounted the
pedestals to be bored, the pedestals are secured by bolts in a slot M³, traversing the
length of the plate or bed M.
In the travelling slide D, are tapped two holes N, into which are screwed the
bosses N¹, of two adjustable hand nuts P, a bolt P₁ passes through each nut, and
secures the plate in position, this position being adjustable to any height or angle,
(by means of the adjustable hand nuts, cup and ball joint) to suit any size of
pedestals.
The pedestals are then passed to a rimering apparatus of similar construction,
and then to a second lathe head R; on the spindle R¹ of which is placed an
adjustable tool holder R2, carrying the required tools or cutters for surfacing and
finishing. To this lathe head is attached a short bed S, upon which is a slide S¹,
on the slide is a turret S2, which is arranged to hold the mandrills S³, of the
different sizes required to hold the pedestals or fittings to be fixed or flanged; the
turret can be moved from or towards the tools by means of a hand lever T, or hand
wheel T and screw T2, and locked by a suitable lever and nut T³.
The pedestal to be finished is placed upon the template mandrill S³ and the
slide is moved up to the cutters by the hand wheel T₁ and screw T2, or by the
hand lever T, and after one side of the pedestal is finished, the turret S² is partially
reversed by hand, so as to allow the pedestal to be reversed the other side is then
surfaced, and the turret being held in position by a spring or other catch U.
A drilling apparatus may be attached to the finishing head, for drilling the grease
holes in the pedestals whilst upon the finishing apparatus.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The general arrangement of apparatus for boring and rimering pedestals, and the
like, substantially as shown and described.
2. The use and employment of the ball and cup for manipulating the slide carrying
the pedestals, substantially as shown and described.
3. The general arrangement of apparatus for surfacing and finishing pedestals,
substantially as shown and described.
4. The combination of the reversible turret S³, catch U, slide S', and lever T,
substantially as shown and described.
