WILLIAM WILSON HULSE of Manchester in the County of Lancaster "IMPROVE-
MENTS IN MACHINERY FOR CUTTING METALS
"
These improvements relate mainly to the means by which either the cutting
tools are actuated or secured, or the work to be operated upon is secured and
adjusted; and they are designed for the most part to promote greater steadiness
and truth in the cutting operations.
In drilling and boring metals horizontally on boring tables, the objects of the
present improvements are attained as follows: namely:
•
The boring spindle is carried upon a slide (the weight of which may be either
wholly or partly counterbalanced) moveable vertically along guides upon a fixed
standard, by means of mechanism which is operated by a handle carried upon the
spindle slide. The boring spindle is driven through a vertical shaft (mounted in
bearings in the fixed standard), by means of bovil wheels one of which is carried
upon the vertical shaft and is moveable along it. The cutting feed is produced
automatically by suitable mechanism. The fixed standard is bolted to a horizontal
base plate provided with bolt grooves, and may be secured at any desired part of
the base plate. One or more stays for carrying the cutting bar may be fixed
upon the base plate, and be provided with mechanism (in connection with that
which moves the spindle slide) by means of which the stay or stays may be
adjusted vertically simultaneously with the boring spindle. This arrangement
admits of the boring spindle and cutter bar being either raised or lowered together,
in correct working line with each other. One or more side tables are secured by
bolts upon the base plate, and each slide table is provided with a slide (having
bolt grooves in its face and sometimes in its side or sides) which is moveable upon
it in suitable guides, at right angles to the axis of the boring spindlo;
tho
movement of each table slide may be produced either manually or automatically,

page_text: and by means of a crank and connecting rod or other suitable device, may be made
reciprocating; each table slido may be moved either simultaneously with, or
independently of, the other or others. The work to be operated upon is secured
on one or more of the table slides according to convenience. The position or
positions of the slide table or tables upon the base plate may be altered from
time to time according to requirement.
In drilling, milling and boring metals vertically, the objects of the present
improvements are attained as follows, viz:-The nose of the spindle is screwed
externally at its upper and lower ends, a plain portion being left between theso
two screwed portions; two respective nuts are fitted on the two screwed portions,
and a sleeve encircles the plain portion; the two nuts serve one for forcing the
sleeve upwards and the other for forcing it downwards along the nose of the
spindle; a taper socket is formed in the nose of the spindle for receiving the shank
(which is of corresponding taper form) of the tool holder or milling tool. A pin
or cotter passes through the sleeve, the nose of the spindle and the shank of the
tool holder or milling tool; the pin or cotter is forced either upwards or downwards
by means of the nuts and sleeve for the purpose of either drawing the tool
holder or milling tool firmly into the socket of the spindle, or of releasing
it therefrom. These improvements may be applied also in drilling and boring
metals horizontally.
In a machine for punching and shearing metals having two rams (usually one
for punching and the other for shearing) the objects of the present improvements
are attained as follows namely:-Each ram is actuated by means of a lever which
is operated by a cam on a hollow shaft. The first motion shaft of the machine
passes through the hollow centre of the cam shaft, and is carried in bearings fixed
beyond the ends of the cam shaft. By the first motion shaft rotation is imparted
to a second motion shaft by means of spur wheels, and by the second motion shaft
-rotation is imparted-to-the-cam-shaft also by means of spur wheels. On one of the
ends of the hollow cam shaft an eccentric is sometimes formed or applied for
actuating shears for cutting angle or other long bars.
In a machine for planing the edges of plates or other similar work, the objects
of the present improvements are attained as follows: namely-The tool carriage
is actuated by means of two screws, gearing into two respective nuts carried by
the tool carriage, the disposition of the screws and nuts being such, as almost, if
not quite, to prevent the tool carriage from cross winding upon the bed or slide
on which it moves. According to one system the scrows are rotated and the nuts
are non-rotative; and according to another system the nuts rotate and the screws
are stationary; in either caso suitable mechanism is employed by means of which
the two screws, or the two nuts, as the case may be, are made to rotate
simultaneously. The tool carriage has both a wide horizontal, and a wide vertical
bearing on the bed or slide along which it moves, and suitable adjusting strips
are applied to it for taking up the strains and wear.
In turning and surfacing work of large diameter in a break lathe, the objects
of the present improvements are attained as follows: namely:-In a recess or hole
(formed for the purpose of admitting work of large diameter) in the part of the
lower bed near the fast head stock, is fitted a bridge piece whose upper face is in
the same plane with the upper face of the under bed, and has bolt grooves
formed in it. The bridge piece is moveable longitudinally by either screw or rack
mechanism, for the purpose of adjusting it to the position best suited to the work
to be operated upon. The slide rest or other apparatus used in operating upon
work of large diameter may be secured either wholly or partly to the bridge
piece.

and truth in tho cutting operations
In drilling and boring metals horizontally on boring tables the objects of the
present improvements are attained as follows viz The boring spindle is carried
upon a slide (the weight of which may be either wholly or partly counterbalanced)
moveable vertically along guides upon a fixed standard by means of mechanism
which is operated by a handle carried upon the spindle slide. The boring spindle
is driven through a vertical shaft (mounted in bearings in the fixed standard) by
'means of bevel wheels one of which is carried upon the vertical shaft and is

mechanism. The fixed standard is bolted to a horizontal base plate provided with
bolt grooves and
may be secured at any desired part of the base plato. One or
more stays for carrying the cutter bar may be fixed upon the base plate and be
provided with mechanism (in connection with that which moves the spindle slide)
by means of which the cutter bar bearing or bearings in the stay or stays may be
adjusted vertically simultaneously with the boring spindle. This arrangement
admits of the boring spindle and cutter bar being either raised or lowered together
in correct working line with each other One or more slide tables are secured by
bolts upon the base plate and each slide table is provided with a slide (having bolt

the table slides according to convenience. The position or positions of the slide
table or tables upon the base plate may be altered from time to time according to
requirement.
In drilling milling and boring metals either vertically or horizontally the objects
of the present improvements are attained as follows viz The nose of the spindle
is screwed externally at its two ends, a plain cylindrical portion being left between
these two screwed portions; two respective nuts are fitted on the two screwed
portions and a sleeve encircles the plain cylindrical portion. the two nuts serve for
forcing the sleeve end wise along the nose of the spindle. a taper socket is formed
in the nose of the spindle for receiving the shank (which is of corresponding taper
form) of the tool or tool holder A pin or cotter passes through the sleeve the
nose of the spindle and the shank of the tool or tool holder and is forced along
with the sleeve either in one direction or the other along the spindle nose by
means of the nuts and sleeve for the purpose of either drawing the tool holder or
milling tool firmly into the socket of the spindle or of releasing it therefrom

the ends of the hollow, cam shaft an eccentric is sometimes formed or applied for
actuating shears for cutting angle or other long bars. In a machine for planing
the edges of plates or other similar work the objects of the present improvements
are attained as follows viz. The tool carriage is actuated by means of two
traversing screws, gearing into two respective nuts carried by the tool carriage
the disposition of the screws and nuts being such as almost if not quite to prevent
the tool carriage from cross winding upon the bed or slide on which it moves.―
According to one system the screws are rotated and the nuts are non-rotative and
according to another system the nuts rotate and the screws are stationary; in
either case suitable mechanism is employed by means of which the two screws or
the two nuts, as the case may be are made to rotate simultaneously. The tool
carriage has both a wide horizontal and a wide vertical bearing upon and against
the bed or slide along which it moves and suitable adjusting strips are applied to
it for taking up the strains and wear.
In the accompanying drawings Fig A. (Sheet 1) is a front elevation of a Boring
Table constructed in accordance with the present improvements, and Fig B. is an
end elevation of the same machine. 1 is the base plate provided with bolt grooves
2 is the fixed standard which may be secured by bolts upon any required part of
the face of the base plate, 3. is a stay (for carrying the cutter bar) which also may
be secured by bolts upon any required part of the face of the base plate, 4 is the
slide which carries the boring spindle 5; this spindle slide is moveablo vertically
along guides upon the fixed standard by means of a hand wheel 6 (which is carried
upon the spindle slide) and of -intermediate mechanism (consisting in the present
instance of a worm shaft worm and worm wheel) imparting rotation to the vertical
screw 7, which works in a nut fixed in the spindle slide; the worm wheel just
mentioned slides upon a feather key along the vertical screw 7. when the spindle
slide is moved either up or down; the vertical screw is mounted in bearings in
the fixed standard and is furnished at its upper end with a bevel wheel 8, which
by means of mechanism as shown communicates the rotary movement of the
screw to a bevel wheel 9; the bevel wheel 9 is keyed upon a screw which moves
the cutter bar bearing in the stay up and down; by means of the arrangement
shown and described the boring spindle and the cutter bar can be raised and
lowered simultaneously in correct working line with each other. The whole or
part of the weight of the spindle slide and of the parts mounted upon it is counter-
balanced by means of a weight 10 which is suspended from a chain which passes
over a pulley as shown and is connected to the spindle slide. The boring spindle
is driven through the vertical shaft 11 (mounted in bearings in the fixed standard)
by means of bevel wheels 12, 13. of which 12 is carried upon the vertical shaft 11,
and is moveable along it; these two bevel wheels 12. 13. communicate rotation to
the boring spindle through the spur wheels 14. 15. of which 15 is keyed upon the
boring spindle. The vertical shaft is driven by means of a cone pulley mounted on
a horizontal shaft and of bevel wheels as shown. The end movement of the boring
spindle for the purposes of adjustment and of imparting feed traverso is produced
by means of the feed screw 16 connected to the right hand end of the boring
spindle; this feed screw works in a nut and is actuated automatically through the
cone pulleys 17. 18 worm 19. worm wheel 20. and bevel wheels 21. 22; 23 is
a clutch for putting the automatic feed mechanism in or out of gear and 24 is a
hand wheel for operating the feed screw manually. The nut in which the feed
screw works is formed in two lengths held in a socket one of the lengths has a
shoulder which bears against one end of the socket and the other length is screwed
externally (for a part of its length which projects beyond the socket) and is fitted
with a nut which bears against the other end of the socket and by means of which

page_text: the distance apart of the two parts of the nut can be adjusted for the purpose of
taking up any play or wear that may occur between the feed screw and the nut ;
the two parts of the nut are prevented from turning round by means of keys-
25., 25 are two slide tables which may be secured by bolts upon any required part
of the base plate 1; each slide table is furnished with a slide 26. 26. moveable in
guides on the respective slide tables at right angles to the axis of the boring spindle;
each of the slides 26. 26¹ has bolt grooves formed in its upper face for enabling the
work to be operated upon to be secured thereon and 26' has one of its vertical sides
extended downwards and formed with bolt grooves for facilitating the fixing of
certain classes of work all or any of the vertical sides of the two table slides may
Tho
be thus extended downwards and have bolt grooves formed in them.
slides 26. 26¹ are actuated by means of respective traversing screws which are
rotated through the intervention of a shaft 27 (having a long key groove) and of
bevel and spur wheels as shown by turning a hand wheel 28; each of the slide
traversing screws is provided with a clutch by means of which it may be put in or
out of gear with its corresponding bevel wheels so that the slides may be operated
either independently of each other or simultaneously In some cases only one slide
table may be employed having a slide with either one or both of its vertical sides
extended downwards and formed with bolt grooves For some classes of work
(such for example as forming cotter holes or the ports of cylinder steam chests)
automatic reciprocating movement may be imparted to one or both of the slides by
means of crank and connecting rod motion driven from the mechanishich
rotates the boring spindle. When the reciprocating mechanism is in gear with one of
the slides its corresponding traversing screw must be out of gear with it. In some
cases the shaft 27. may be actuated automatically from the mechanism which
rotates the boring spindle. When very long cutter bars are used two or more stays
may be employed each having their cutter bar bearing moveable up and down as
described and shown in the case of the stay 3 simultaneously with each other and
with the boring spindle
Fig C. is a drawing partly in section of the nose of a spindle suitable for either
a drilling milling or boring machine (whether vertical or horizontal) constructed in
accordance with the present improvements; 1 is the spindle with its noso 1'
screwed externally at its two ends so as to leave a plain cylindrical portion between
these two screwed parts; 22' are the nuts which fit upon the two screwed parts
respectively and 3 is the sleeve which is placed between the two nuts and encircles
the plain cylindrical portion of the spindle nose by working the nuts 2, 2¹, the
sleeve 3 can be forced end wise along the nose; a taper socket as shown is formed
in the nose of the spindle for receiving the taper shank 4 of the tool or tool
holder; 5 is a pin or cotter which passes through the sleeve 3. spindle nose 1' and
shank 4-when this pin or cotter is in position and the sleeve 3. is forced in one
direction the shank 4 is drawn up tight into its socket, and when the sleeve is
forced in the other direction the shank is loosened in the socket; when it is
required to remove the tool or tool holder the pin or cotter (after the shank has been
loosened in its socket) is withdrawn. This method of fixing and loosening the
tools and tool holders serves to prevent injuries to which they are liable under
existing methods and which disturb the accuracy and steadiness of their working.
Fig D. is a side elevation of a Punching and Shearing machine constructed in
accordance with the present improvements and Fig E. is an end view partly in
section of the same machine. 1. is the body of the machine, 2. is the punching
ram operated by the lever 3 and 4 the shearing ram operated by the lever 5.; 7 is
the cam shaft having a hollow centre and mounted in bearings as shown in Fig E.
and provided with cams 6. 6¹ for actuating the levers; 8 is the first motion shaft
of the machine which passes through the hollow centre of the cam shaft and is
carried in bearings as shown in Fig E. situated beyond the ends of the cam shaft;
15 is the second motion shaft of the machine which is driven from shaft 8. by
means of the two spur wheels 9. 10. and drives the cam shaft 7. by means of the
two spur wheels 11. 12.; 13 (Fig E). is a ram for cutting angle and other bars

page_text: and is driven from the cam shaft by means of an eccentric (not visible in the
drawings) either formed or fixed upon it and of the eccentric eye and rod 14.
Fig F. is a front elevation of a Plate Edge Planing Machine constructed in
accordance with the present improvements and Fig G is an end view partly in
section of the same machine. 1. is the bed of the machine 2. is the tool carriage
traversed to and fro along the bed of the Machine by means of the two rotating
traversing screws 3. 4. which gear into corresponding nuts fixed to the tool
carriage; 5 is the driving shaft of the machine and is furnished with two sets of
driving pulleys one for producing the cutting traverse of the tool carriage and the
other for producing its quick return movement; on the driving shaft 5, is the
spur wheel 6. which communicates simultaneous rotation to the traversing
screws 3. 4. by means of the spur wheels 7. and 8. keyed on the two traversing
screws respectively. The tool carriage 2. has in addition to the ordinary horizontal
bearing upon the bed a wide vertical bearing against it as shown in Fig. G
suitable adjusting strips being provided as shewn in the same Fig: for taking up
the strains and wear; this arrangement of bearings for the tool carriage gives
increased steadiness to its movements and the arrangement of the two traversing
screws for actuating the tool carriage assists towards the same end and in a great
measure counteracts the tendency of the tool carriage to cross wind in its guides.
In some cases the two traversing scrows may be made non rotative and their two
corresponding nuts (mounted in the tool carriage) may be made rotativo.-Under
this arrangement the spur wheels 7. and 8. are secured upon the two nuts
respectively instead of upon the two screws (or the nuts may be formed as spur
wheels) and the driving shaft 5. is extended along the whole length of the bed or
thereabouts and has a long key groove formed in it for receiving a feather key
fixed in the spur wheel 6. which communicates simultaneous rotation to the two
nuts and being confined between cheeks on the tool carriage is carried endwise
__along the shaft 5, as the tool carriage is traversed.along its..bed.
