Improvements in the Method of and Machinery for Making Nuts
and the like
We, FRANCIS BERRY and CHARLES BERRY of the Firm of Messrs Francis
Berry and Sons, Engineers Tool Makers, Sowerby Bridge in the County of York,
THOMAS HENWOOD of 4 Alfred Road Devonport and SIDNEY HERBERT
NEWCOMBE of 10 Rodney Terrace, St Budeaux, near Devonport in the County
of Devon, Engineers, do hereby declare the nature of this invention, to be as
follows
The object of our invention is to construct nut making machines, so as to
automatically face mill or shape all the sides of the rods simultaneously bore the
holes in same, and cut off the required length at one operation
We place a suitable rod from which the nuts are to be made, in a milling
machine constructed so as to mill or shape all the sides of the nuts simultaneously,
this is accomplished by placing the said rod upon suitable holders, which rod is fed
forward through the milling cutters automatically by suitable gearing and catch
wheels mounted upon the machine frame
These milling cutters we fix upon a suitable disc, and are of a desired number
according to the number of sides requied upon the nut, they are also fixed in the
said disc out of centre alternatively, and are diven each independently and by
means of preferably pulleys and ropes, by this construction all the sides are
operated upon simultaneously
After the said rod has been milled or shaped to the desired section, it is placed
upon suitable holders or carriers upon the apparatus for boring and cutting off
the nut
When in position, a suitable drill mounted upon a slide operated by cam,
same after which it is
connecting rods, and levers, bores the desired hole in
withdrawn, by means of the cam before desciibed Simultaneously a second cutter
mounted upon a second slide (operated by cams, catch and catch-wheel, and leveis
tbus, at
working at right angles to the said rod) cuts off the desired length of nut
the same time the drill is drilling the hole in the bar, the second cutter is cutting
off the nut the required length, but, it is so set that the drill or fist cutter finishes
its work first
The cutters and drill upon their slides or carriages are moved up the rod into
position for boring and cutting off another nut by means of suitable cains, catch
and catch-wheels, worm worm-wheel and cone pulleys mounted upon the machine
frame
After the cutter has cut off the nut it continues to be fed forwards and faces
the end of the bar or rod rounding off the edges simultaneously, after which it is
withdrawn for the next operation
When the nut is cut off it is placed in a nut tapping machine, attached to the
bed of the aforesaid machine, where it is tapped and finished

We place a suitable rod or bar A from which the nuts are to be made in 1
milling machine, constructed so as to mill or shape all the sides of the nuts
simultaneously, this is accomplished by placing the said rod upon suitable holders
or carriers B, B₁ the said rod A is fed forwards through the milling cutters C
automatically, by means of pawl C¹ and gear wheels C3 and C³ operated from the
driving shaft B2, the wheel C3 operating a screwed shaft D which feeds or pulls
the holder or carrier B' forwards, so feeding the rod up to the cutters C, the bar
may be moved quicker or slower through the cutters by means of suitable change
wheels C, C³, C® and C7
The milling cutters C are mounted upon a suitable standard or disc E (of any
desired number, according to the number of sides required upon the nut) and are
preferably placed alternately out of centre, and are driven each independently and
preferably, by pulleys E' and 1opes E2 or by suitable gearing from the main
driving pulley B³ and cone F', by means of auxilliery pulleys F' or gearing
mounted upon a su able standard G fixed upon the machine fiame
When the sides have been milled a suitable arill K (fixed in a stand or rest K¹)
18 operated by cam L and connecting rod and lever Land L2 for feeding same to
the bar A which is caused to evolve by means of cone pulleys M or other suitable
driving gear, fixed upon standards M' on the machine frame Simultaneously
while the drill is boring the required hole in the bar a parting and chamfering
tool N fixed in holder N¹ upon a saddle N2 and operated from the cam L by
lever Pand connecting rod P" cuts off the nut and chamfers the end of the bar
for the next nut, but is so set that the drill K has finished its work fist, and been
with drawn before the said parting tool cuts off the nut

page_text: When the parting and chamfering tool has cut off the nut, the tool is withdrawn
and moved the required distance along the bar for cutting off the next nut by
means of cam L operating levers L, L, L' and connecting rod L which operates
ratchet R and ratchet wheel R' bringing the said parting and chamfering tool into
position for cutting off another nut
When required to move the drill up to its work before starting the machine, we
turn the pawl R out of gear with the catch wheel R' and by means of handle X
keyed on to a cross shaft X' carrying a pinion Y gearing with rack Z upon the bed
of the machine, the saddle carrying drill and other mechanism for cutting and
chamfering the nuts is quickly brought into the desired position
We preferably drive the cam L by means of shaft T driven by worm U and
worm wheel U bevel wheels V and cone pulleys W operated from the driving
shaft of the machine
When the nut is cut off it is placed in a nut tapping machine, attached to the
bed of the aforesaid machine, where it is tapped and finished
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 18
-
1 In machinery for making nuts, the arrangement of milling cutters C mounted
upon a standard E, for milling all the sides of the nuts simultaneously, substantially
as shown and described
2 In milling machines for making nuts, the combination of the cutters C,
mounted upon standard E, and screwed shaft D arranged and operated in the
manner and for the purposes substantially as shown and described
3 In machinery for making nuts, the arrangement of drill, parting, and
chamfering tool, for boring, cutting off and chamfering nuts simultaneously in the
manner and for the purposes described
4 In nut making machinery the combination of a drill K, parting and

and operating in the manner and for the purposes substantially as shown and
described
5 The general arrangement and construction of machinery for making nuts
substantially as shown and described
Doted this First day of February 1896
