The object of our invention is to construct nut making machines,
matically 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 forwards through the milling cutters automatically by suitable gearing and
catch wheels, mounted upon the machine frame.
We fix the milling cutters which are of a desired number according to the number
of sides required upon the nut preferably upon spindles upon the working bed of
the machine, upon the top spindle we preferably fix four cutters of suitable shapes,
and upon the bottom spindle two, these spindles are driven by suitable gearing
driven by cone pulleys worm and worm wheel and spur wheels; by this arrange-
ment of cutters 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, con-
necting rods and levers, bores the desired hole in same after which it is withdrawn
by means of the cam before described.
Simultaneously a second cutter mounted upon a second slide (operated by cams,
and levers working parallel to the said rods) cuts off the desired length of nut.
Thus at 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 first
cutter finishers 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 cams, 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

page_text: end of the bar or rod rounding off the edges simultaneously, after which it is with-
drawn 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.

COMPLETE SPECIFICATION.
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 and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of our invention is to construct nut making machinery so as to auto-
matically face, mill or shape all the sides of the rods from which the nuts are to
be made, simultaneously bore the holes in same, and cut off the required length
at one operation; this being a further improvement upon our Patent No. 87969.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a side elevation of apparatus for milling or shaping the sides of the
bar from which the nuts are to be made.
Fig. 2, is a plan of Fig. 1.
Fig. 3, is an end elevation of Fig. 1.
Fig. 4, is a side elevation of our apparatus for boring, cutting off the nut, and
chamfering the end of the bar for the next nut.
Fig. 5, is a plan of Fig. 4.
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 nut simultaneously,
this is accomplished by a new construction and arrangement of cutters, mounted
upon a suitable headstock or fixed carriage A, the rod to be milled or shaped is
placed upon a holder or holders B, and fed forwards through the milling cutters
automatically by means of a screw C, passing through the holder carriage D, and
driven by worm wheel E, and cone pulleys E', operated from any convenient driving
shaft.
We fix the milling cutters which are of a desired number and shape according
to the number of sides required upon the nut, preferably upon spindles or
shafts F, G, mounted upon the aforesaid carriage A, upon the top spindle F we
preferably fix four cutters, the two central cutters H, H having a bevel cutting
face, and the two outer cutters J, J' a straight or horizontal cutting face; these
cutters as arranged and operated form four sides of the nut or bar.
Upon the bottom spindle G, we mount two more cutters K, K' which mill or
shape (when making hexagonal nuts) the remaining sides of the bar.

page_text: These cutters are driven at the required speed, by means of a large pinion wheel L,
operated by a smaller pinion wheel L, driven by gear wheels M, and cone pulleys N
from any suitable driving shaft, the top spindle or shaft operates the bottom shaft
by means of pinion wheels N¹.
After the rod has been milled or shaped to .the desired section, it is placed (see
Figs. 4 and 5), upon the apparatus for boring and cutting off the nut.
This apparatus consists of a suitable lathe bed P, upon which are mounted a
fixed headstock P, and cone pulleys 1, these cone pulleys are mounted upon a
hollow shaft R, which acts as a holder or support for the hexagon or other bar,
when of a length more or less extensive; upon one end of this hollow shaft we fix
a holder S, which, by means of a screwed stud or studs S¹, attaches the bar to the
shaft, and upon the said shaft being operated it also revolves the bar.
A drill T mounted upon a sliding carriage or drill holder T" operated by cam U,
connecting rods U¹, and lever U2, is fed up to and bores the desired hole in the
end of the bar, immediately this is accomplished the drill is withdrawn by the
aforesaid cam and levers.
While the drill is boring the required hole in the end of the bar, a cutter V
mounted upon a cross slide V¹ upon a carriage T2, cuts off the desired length of
nut, but the drill and cutter are so arranged or set that the former finishes its work
first and is withdrawn before the cutter has cut off the nut.
For operating the cutter V, we preferably attach to the cross slide, a connecting
rod V2, connected to a lever V3, upon which is mounted an antifriction bowl or
runner, operated upon by means of a cam W attached to the side of the worm
wheel X, upon a stud X, this mechanism feeds the cutter at intervals as desired.
When the cutter has cut off the nut it continues forwards and faces the end of the
bar or rod, rounding off the edges for the next nut, after which it is withdrawn.
When the nut has been cut off the end of the bar chamfered, and the tool with-
drawn, another antifriction bowl or runner Y, mounted upon one end of an arm or
lever Y¹ engages with a recess in the side of the worm wheel X and disengages a
lock nut Z fixed to the other end of the lever Y¹ from the screwed spindle 72,
mounted on the bed of the machine, immediately this is accomplished, a further
cam W connected to or forming part of the wheel, operates upon a bowl or
runner W2, fixed upon one end of a pivotted rocking lever W³, this lever is con-
nected with the sliding carriage T2 by connecting rod W* so that as the cam W
acts upon the bowl W at one end of the lever W³, the latter, by means of the con-
necting rod, moves the carriage T2 the requisite distance, this movement takes place
whilst the bowl Y is within the recess in the wheel X, and the lock nut Z disen-
gaged from the screwed spindle.
As the bowl Y passes out of the recess in the side of the wheel X, by the continued
movement of such wheel, the nut Z engages with the screwed spindle Z2, and holds
the carriage T rigid during the next operation of boring and cutting off the nut;
or until the carriage is required to be moved as described. The spring X2 is to
keep the bowl Y tight to the face of the wheel X, the object of which will be
understood.
When the nut is cut off, it is placed in a nut tapping machine, which may be
fixed to the bed of the aforesaid machine where it is tapped and finished.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would have it understood
that we are aware that in nut making machinery, the rods or bars from which the
nuts are made, have had all their sides milled or shaped simultaneously, also that
such rods or bars have been bored and cut and chamfered automatically, but we
declare that what we claim is:-
1. In nut making machinery the construction and arrangement of cutters H, H¹,
J, J, and K K' in the manner and for the purposes set forth.
2. In nut making machinery, the employment of worm wheel X, cams U, W,

page_text: and W upon a stud, operated and operating the levers and connecting rods for
automatically feeding the drill, cutter, and carriage, in the manner and for the
purposes set forth.
