Year: 1869

page_text: LETTERS PATENT to Thomas Vaughan and Emile Watteeu, both
of Vulcan Works, Middlesborough-on-Tees, in the County of York,
for the Invention of "A NEW OR IMPROVED MACHINE FOR NUTTING
SCREW BOLTS."
Sealed the 23rd November 1869, and dated the 26th May 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Vaughan and
Emile Watteeu at the Office of the Commissioners of Patents, with
their Petition, on the 26th May 1869:
WC, THOMAS VAUGHAN and EMILE WATTEBU, both of Vulcan Works,
Middlesborough-on-Tees, in the County of York, do hereby declare the
nature of the said Invention for "A NEW OB IMPROVED MACHINE FOR
NUTTING SCREW BOLTS," to be as follows:-
Our Invention has reference to a new or improved machine whereby
the nuts are screwed on to bolts in a continuous and expeditious manner,
and without being tightened to a greater extent than would be the case
if screwed on by hand. For this purpose we arrange two vertical

page_text: opposite dises a certain distance apart, but connected together in an
adjustable manner so as to regulate their distance apart to the length of
the bolts to be nutted, for which purpose a central cylinder on the one
disc fits into a central recess in the other, which cylinder is capable of
being made to slide in the recess by means of an adjusting screw. The
dise having the recess is of considerable depth and is made to revolve
slowly in bearings formed in a fixed framing carrying with it. the second
disc, rotary motion being imparted by a spur pinion in gear with a spur
rim fixed to the first disc and receiving motion through speed reducing
gearing from a driving shaft carrying a fast and loose pulley. The first
or recessed disc carries near its circumference a number of spindles
passing through it, and made to revolve in it at the same time that it is
itself revolving by means of a spur wheel on the before-mentioned
driving shaft in gear with a spur pinion carried by each of the spindles,
and connected thereto by a conical or other friction clutch, so that when
the spindles offer more than a certain resistance to rotation the spur
pinions will turn thercon without rotating the spindles. At the front ends
these spindles have recesses for receiving the nuts to be screwed on to
the bolts, which are placed in notches exactly opposite such recesses
formed in the periphery of the second disc. Removeable dies are fitted
both in the said notches and in the recesses for receiving bolts and nuts
of varying sizes. A nut having been placed in one of the recesses and a
bolt to be nutted in the opposite notch, the rotation of the spindle
carrying the nut as it is itself carried round by the revolving discs will
cause the nut to be screwed on to the bolt in such manner that when by
the rotation of the discs the bolt has been carried round into such a
position that it will drop out of the notch the nut will have been
screwed to a sufficient extent thercon, while the screwing on of the nut
beyond a certain degree of tightness will be prevented by the before-
described yielding connection between the spindle and its pinion. In
this manner bolts and their nuts may be continuously introduced
into their respective notches and recesses as these rise up on one
side of the machine by the rotation of the discs, and the nutted
bolts will drop out in a like continuous manner on the other side of
the machine.

borough-on-Tees, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of May, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Thomas Vaughan and Emile Wattceu, Her
special licence that we, tho said Thomas Vaughan and Emile Watteeu,
our executors, administrators, and assigns, or such others as wc, the said
Thomas, Vaughan and Emile Wattceu, our executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter, during the term therein expressed,, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "A NEW OR IMPROVED MACHINE FOR NUTTING SCREW BOLTS,"
upon the condition (amongst others) that we, the said Thomas Vaughan
and Emile Wattceu, our executors or administrators, by an instrument
in writing under our or their hands and seals, or under the hand and,
scal of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the dato
of the said Letters Patent.
NOW KNOW YE, that I, the said Emile Wattecu,, on behalf of
myself and the said Thomas Vaughan, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed,.
to be particularly described and ascertained in and by the following
statement thereof, reference being had to the acconipanying Sheet
of Drawings, and to the figures and letters marked thereon, that is to.
say:-
Our Invention has reference to a new or improved machine whereby
the nuts are screwed on to bolts in a continuous and expeditious manner,

page_text: and without being tightened to a greater extent than would be the case
if screwed on by hand. For this purpose we arrange two vertical
opposite discs a certain distance apart, but connected together in an
adjustable manner, so as to regulate their distance apart to the length of
the bolts to be nutted, for which purpose a central cylinder in the one
disc fits into a central recess in the other, which cylinder is capable of
being made to slide in the recess by means of an adjusting screw. The
disc having the recess is of considerable depth, and is made to revolve
slowly in bearings formed in a fixed framing, carrying with it the second
disc, rotary motion being imparted by a spur pinion in gear with a spur
rim fixed to the first disc, and receiving motion through speed reducing
gearing from a driving shaft carrying a fast-and-loose pulley. The first
or recessed disc carries near its circumference a number of spindles
passing through it, and made to revolve in it at the same time that it is.
itself revolving by means of a spur wheel on the before-mentioned
driving shaft in gear with a spur pinion carried by each of the spindles,.
and connected thereto by a conical or other friction clutch,, so that when
the spindles offer more than a certain resistance to rotation the spur
pinions will turn thereon without rotating the spindles. At the front
ends these spindles have recesses for receiving the nuts to be screwed on
to the bolts, which are placed in notches exactly opposite such recesses
formed in the periphery of the second disc. Removeable dies are fitted
both in the said notches and in the recesses for receiving bolts and nuts
of varying sizes. A nut having been placed in one of the recesses and a
bolt to be nutted in the opposite notch, the rotation of the spindle carry-
ing the nut as it is itself carried round by the revolving discs will cause
the nut to be screwed on to the bolt, in such manner that when by the
rotation of the discs the bolt has been carried round in such a position
that it will drop out of the notch the nut will have been screwed to a
suflicient extent thercon, while the screwing on of the nut beyond a
certain degree of tightness will be prevented by the before-described
yielding connection between the spindle and its pinion. In this manner
bolts and their nuts may be continuously introduced into their re-
spective notches and recesses as these rise up on one side of the machine
by the rotation of the discs, and the nutted bolts will drop out in a like
continuous manner on the other side of the machine.
Having thus set forth the nature of our Invention, we will now
proceed more particularly to describe the manner of performing the
same, for which purpose we shall refer to the accompanying Sheet of

page_text: Drawings, in which Figure 1 shows a side elevation of the improved
nutting machine; Figure 2 shows a front elevation of the same; and
Figure 3 shews a vertical section thereof. Similar letters of reference
indicate similar parts in each of the Figures.
A is a disc or cylinder made to revolve in the framing B by means of
the fast-and-loose driving pulleys C, O', the shaft D of which runs frec
in a bearing E formed in the cylinder, and carries a spur pinion Fin
gear with a spur wheel G fixed on the boss of a pinion H running
loose upon the spindle I carried by the framing B. The pinion H is in
gear with a spur rim J fixed on the cylinder A, which thus receives a
slow rotary motion from the pullies C, C'. Near the periphery of te
cylinder A a number of cylindrical holes are formed through the same,
into which are fitted spindles K formed at. their front ends with recesses,
in which are fitted dics or sockets L for receiving the nuts M' to be
screwed on to the bolts M carried in notched sockets N¹ fixed in a
removable manner on the circumference of the disc N. This disc is
carried in an adjustable manner by the cylinder A, a cylindrical pro-
jection O being made to slide with a feather in a corresponding recess P
in the cylinder A, and the adjustment of the disc N farther from or
nearer to the cylinder (according as longer or shorter bolts require to be
nutted) being effected by means of the screwed spindle Q fixed to the
rear end of the cylinder A, and passing through the rotatable screwed
bush R carried by the disc N. A lock nut R' is provided for securing
the disc in position when once adjusted. Upon the rear ends of the
spindles K are fitted spur pinions S, which by means of the conical
washers T and screw nuts U are frictionally coupled to the spindles K.
The pinions S are in gear with the spur wheel V fixed upon the shaft D of
the driving pullies C, C', so that the rotary motion of the latter is thus
imparted to the pinions S, which therchy cause the spindles K to revolve
in the cylinder A, while at the same time they are carried round thereby.
From this arrangement it will be seen that if the bolts to be nutted be
placed in the sockets M', as shewn, and the nuts be placed in the dies or
sockets L opposite the bolts, then, as the bolts and nuts are carried
round by the rotation of the cylinder A and disc N, the simultaneous
rotation of the spindles K in the disc A will cause the nuts to be screwed
on to the bolts, the speed with which the spindles rotate being so
adjusted that if the bolts to be nutted as also the nuts are inserted into
their respective sockets or dies on one side of the machine, then by the
time the disc N has travelled round into such a position that the said

page_text: bolt will fall out of its socket the nut will have been screwed on to the
latter to the required extent. The frictional coupling of the pinions S to
the spindles K prevent the nuts from being screwed on to the bolts with
a greater degree of tightness than is required, as when the spindles K
offer more than a certain degree of resistance to rotation the pinions S
will turn upon the spindles without causing these to revolve.
The machine is rendered available for nutting bolts of various sizes;
firstly, by the adjustment of tho disc N, as described; and, secondly, by
fixing upon this disc and into the spindles K sockets or dics N and L
corresponding in size to the particular bolts and nuts to be acted upon.
Having thus described the nature of our Invention, and in what
manner the same is to be performed, what wo claim under the herein.
before in part recited Letters Patent is,―
First. The construction of improved machinery for nutting bolts
wherein the bolts being placed in notches or sockets on a rotating disc
have the nuts screwed thereon by means of rotating spindles carried by a
revolving cylinder, which also carries round the said disc, substantially
as herein-before set forth.
Second. Imparting motion to the said nutting spindles by means of
pinions frictionally coupled to the spindles, substantially as and for the
purposes set forth.
Third. The peculiar adjustable connection of the disc carrying the bolts
to the revolving cylinder herein-before described.
Fourth. We claim in combination the general arrangement of machinery
for nutting bolts herein-before described, with reference to the accom-
panying Sheet of Drawings.
In witness whereof, I, the said Emile Watteou, have hereunto set
my hand and seal, this Twenty-third day of November, in the
year of our Lord One thousand eight hundred and sixty-nine.
EMILE WATTEEU. (L.S:)
