Improved Apparatus or Machine for Boring, Planing Ourved
Surfaces, Screw-cutting, and Rifling and Milling Metals.
1, CHARLES RISBEE IORNS of Altrincham, Cheshire, Engineer do hereby
declare the nature of this invention to be as follows:-
This invention relates to a combined machine for boring, radial planing,
screw-cutting, rifling and milling at one setting of the article to be operated upon.
For this purpose, I employ a hollow tube or ram, which has a nut fixed in one
end, and an arrangement for carrying a cutting tool at the other. In this nut,
runs a driving screw, which is actuated by spur gears, worm and wheel and driving
pulleys with open and cross belts. I also fix on the hollow tube or ram, worm
wheel, which is driven through longitudinal shaft from the driving pulleys. This"
worm wheel can be used either for driving the bar for boring, or as a hand feed
for radial planing. For the feed in boring, screw-cutting and rifling, I introduce
a swing framo and change wheels, thus changing the relative speed between screw
and bar. The spur gears for planing, and the worm wheels on screw and ram
for boring, can be connected or disconnected independently by means of clutches.
For planing and rifling, the spur wheel clutch is thrown into gear, the worm
wheel clutches then being disengaged. This revolves the screw at a high speed,
thus driving the tube or ram forwards or backwards; the radial feed being
applied by hand by means of the worm wheel on the ram.
For boring, the worm wheel on ram is put into gear giving the ram a revolving
motion, the worm wheel on screw is then driven from the ram by means of the
swing frame and change wheels, thus giving the ram a longitudinal motion in
either direction, and putting on the feed according to the wheels used.
For milling and turning, the worm wheels on screw and ram are put into gear
by means of the clutches, the screw and ram thus revolving together.
The varying speeds for boring and milling are obtained by means of two
countershafte, carrying necessary cones and pulleys.
By the introduction of bed placed in front of machine with revolving table
mounted on compound tables, and arranged to rise and fall, the operations of
ordinary planing, face and circular milling, also shaping of irregular forms can
be accomplished.

motion in radial planing.
1 employ a hollow tube or ram A, which has a nut B fixed in one end, and
arranged for carrying a cutting tool at the other. In this nut B, runs a driving
screw C, which is actuated by spur gears D and E and driving pulleys H with
open and cross belts, worm F and wheel G for feed motion. I also fix on this
hollow tube or ram A, a worm wheel J, which is driven through a longitudinal
shaft K from the driving pulleys H. This worm wheel J can be used either for
driving the bar A for boring, or as a feed for radial planing. For the feed in
boring screw-cutting and rifling, I introduce a swing frame Land change wheels M,
thus cbanging the relative speed between screw C and bar A. The spur gears D
and E for planing, and the worm wheel G and J' on the screw C aud ram A for
boring, can be connected or disconnected independently by means of clutches N
and O, which are prevented from revolving on their shafts by means of two square
keys, which are sunk for half their depth in the shafts, the other halt projecting
aud fitted to grooves, which are cut in the clutches, but being sufficiently loose to
allow the clutches to be moved end wise, and thus brought into gear with wheels E
and G and shaft K and wheel D as required, and held in position by set-screws.
For planing and rifling, the spur wheels D and E are thrown into gear by means of
clutches and O, the worm wheels G and J thus being disengaged. This
revolves the screw C at a high speed, thus driving the tube A forwards or
backwarde. To shift the belts and thus produce the forward and back motions,
1 employ two swinging arms or belt forks H'H' these are moved by bevelled
projections or a slot in the sliding strip Z, so arranged that when this strip Z,
slides in either direction, the shifting arms H'H' are moved differentially, that is,
one moves before the other alternately, to such extent that the driving belt, then
acting on the middle or fast pulley will be shifted to the outer or loose pulley
before the other belt engages and reverses the direction of the middle pulley and
screw C. By this meaus there is no slip of the belts and therefore no power is lost
by friction, as the belts do not act one against the other. The sliding strip Z is
moved by the reversing rod P, which has movable stops or tappets, which can be
set to produce any stroke desired. This rod P has also two fixed or safety stops,
so that the bar A cannot overrun itself. A lever not shown on the drawings, cau
be coupled to the reversing rod P, so that the machine can be reversed or stopped
at any point of the stroke by shifting the belts.
The radial feed is applied by hand by means of the worm wheel J' actuated by
worin J on the spindle T, or automatically by reversing rod P actuating piniou Q
through rack P connected to feed disc S by spindle R, thus oscillating the disc S
at each end of stroke, this motion being conveyed to ratchet wheel V ou worm
shaft T by connecting link U and pawl V'.
The feed can be reversed by changing position of pawl V'; the amount of feed
being regulated by sliding studs U' nearer to or farther from the axis along slot S¹
in disc S.
For boring, the worm wheel J is put into gear giving the ram A a revolving
motion. The worm wheel G on screw C is then driven from shaft K by means of
a swing frame L and change wheels M, thus giving the ram A a longitudinal
motion in either direction, and putting on the feed according to the ratio of
change wheels employed.
For milling and turning, the worm wheels J' and G are put into goar by means
of the clutches N and O, the screw C and the ram A thus revolving together. The
varying speeds for boring and milling are obtained by means of two countershafts
carrying the necessary cones and pulleys.
By the introduction of a bed placed in front of the machine with revolving table
mounted on compound tables and arranged to rise and fall, the operations of
ordinary planing, face and circular milling, also shaping of irregular forms, can be
accomplished.
