Improvements in Milling, Drilling, and like Machines, applicable for
use in the Manufacture of Cycles and other Machines.
WALTER CHATWOOD BURTON of 7 Rose Villa, Latchford, Warrington
Mechanical Engineer, and FRANCIS WILLIAM KILLING BECK of Grappenhall
Road Latchford Warrington, Cycle Fitter, do hereby declare the nature of this
invention to be as follows:-
Our said invention relates to an improved, drilling milling & forming machine,
which entirely obviates the filing of oval or similar shaped lugs, so commongly
used in cycle and similar construction, and whereby unskilled labour can produce
vast numbers, of any article or shape exactly alike to any pre arranged size or
templet and thus effect an enormous saving in time and labour, besides attaining
perfect angles, so important in machine and cycle construction. It can also be
used as an ordinary drilling and milling machine.
Our said invention consists mainly in constructing and arranging a machine so
as to have a revolving vertical spindle, arranged with a chuck for holding milling
cutters or cutting tools. The table being so arranged that it is geared to revolve
centrally or in the same plane as the spindle, yet is devised as to swing or radiate
horizontally. Upon this table we fix our gigs, or angle plates, upon which the
work to be operated upon is fixed. To the spindle of the table two formers are
fixed at right angles to each other. These formers work into contact with two
rollers fixed to the feed slide. The feed table is supported from the main body
of the machine, the formers being between & in contact one with each of the two
rollers causing a swinging motion of the table, the formers always actuating the
slide, rollers without the intervention of springs. Disengaging mechanism may be
applied (so that ordinary milling may be accomplished) to liberate table from
revolution and fix it for ordinary milling purposes or for drilling. Springs or
equivalent mechanism may be used for keeping the former, against the roller if
desired.

WALTER CHATWOOD BURTON of 7 Rose Villa or 7 Grappenhall Road
Latchford, (near Warrington) in the County of Chester Mechanical Engineer, and
FRANCIS WILLIAM KILLING BECK, of 7 Grappenhall Road, Latchford, (near
Warrington) in the County of Chester, Cycle Fitter, 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 :-
Our said invention relates to an improved devise, or method, or mechanism for
producing, true clean, curved, accurate, oval or similar shaped lugs, so commongly
used in cycle & similar constructions, thus dispensing with filing, and attaining
accuracy, without skilled labour, and produce vast numbers, of any article or
shape, exactly alike, to any pre arranged size or templet, thus effecting an enormous

and cycle construction. It can also be used as an ordinary drilling, and milling or
wheel cutting machine.
Our invention consists mainly in constructing devising, and arranging a machine
so as to have a revolving vertical spindle, arranged with chuck for holding milling
cutters or cutting tools the table being so arranged that it is geared to revolve
centrally or in the same plane as the spindle, yet so devised as to slide and swing
or radiate horizontally. Upon this table we fix our gigs or angle plates, upon
which the work to be operated upon is fixed. To the spindle of the table, two
formers are fixed, at right angles to each other. These formers work in contact
with two rollers fixed to the feed slide. The feed table is supported from the
main body of the machine. The "formers" being between and in contact with
each of the two rollers cause a swinging motion of the table. The "formers
always actuating the slide rollers without the intervention of springs. (Springs or
equivalent mechanism may be used for keeping the "formers against the rollers
if desired). Disengaging mechanism may be applied (so that the ordinary milling
may be accomplished) to liberate the table from revolution and fix it for ordinary
milling purposes or for drilling.
"
In order that our invention may be better understood we have caused to be
annexed hereto, a sheet of drawings in which similiar letters of reference refer to
corresponding parts of the machine.
Fig. 1, is side elevation of the machine.
Fig. 2, is side elevation of modefied driving.
Fig. 3, plan of swing table.
Fig. 4, side elevation shewing automatic feed.
Fig. 5, front elevation of formers and table.
Fig. 6, plan of modified driving.
Fig. 7, front elevation of forming arrangement.
Upon
In Fig. 1, a, represents the vertical spindle driven to revolve by strapping
driving from cone, c; a', is the body or frame work of the machine; n, the cutting
tool, operating upon the work or material fixed in gig, n', upon table, m; s, is a
spur wheel fixed upon spindle and drives wheel, t, and its upright shaft, o.
this upright shaft, below the swinging arm, i, is fixed wheel or pinion, h, and this
transmits motion of revolution to the wheel, h, and consquently to the table, m.
Hand wheel, g, worm, w, and worm wheel, w³, acting upon a rack are used to adjust
the table vertically. The spindle, z, has upon its lower extremity the cam, oval,
eccentric, round or other shaped former 1 and a similiar or duplicate former, 2, placed
upon the spindle at right angles to former, 1 both being in an horizontal plane ;
5, is the slide; 6 the bracket or table supporting the slide; 7, the feed motion.
Upon the slide are fixed two rollers, 3, and 4, working in contact with the
formers, 1, and, 2. It will thus be seen that any motion of spindle, a, upon which
the irregular or cam, or other shaped formers, 1, and, 2, are fixed will produce a
swinging motion of the swinging arm, i, consequent upon the formers working
against the bowls, 3, and, 4. By turning the screw, 7, the feed advances, and
causes the milling cutter to mill off the metal or work to the desired size and of
the formation, given by the shape of the formers beforementioned.
In Figures, 2, and, 4, the driving of the table is attained by gearing independant
of spindle, e, being a pulley which is driven from cone, c, shaft, e, partakes of the
motion and through worm ' drives the worm wheel, f upon shaft, o, thence
wheel, h, drives wheel, h', and the table and formers, 1, and 2
The table is disengaged from revolving when required to be used as a wheel
cutter or fixed milling or drilling machine, by actuating clutch, 10, on upright
shaft, o.
The automatic feed of the slide is attained by fixing a rachet lever and paul
mechanism from shaft, o, to engage with feed wheel, K, upon the screw, 7, in slide, 5.
In Figure, 6, the table is shown driven from cone on shaft, 16, through bevels, 15,
and, 14, and worm wheel, 13.

page_text: By this arrangement we may attain an horizontal sliding motion of the swing
arm, . Other modifications of driving may be used.
Having now fully described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we
claim is
1st. In milling or forming machines, a swinging arm, ¹, actuated by two
formers, 1, and, 2, fixed upon spindle, x, of the table as substantially described and
illustrated.
2nd. The arrangement devise or mechanism of formers fixed at right angles upon
a spindle as substantially described and illustrated.
3rd. The devise or arrangement of disengaging motion whereby the table is
rendered stationary for ordinary milling or drilling purposes substantially as:
described and illustrated.
