AN IMPROVED NUT TAPPING MACHINE
Year: 1867

page_text: LETTERS PATENT to Emile Watteeu, of Middlesboro'-on-Tees, in the
County of York, for the Invention of "AN IMPROVED NUT TAPPING
MACHINE."
Sealed the 17th September 1867, and dated the 23rd March 1867.
PROVISIONAL SPECIFICATION left by the said Emile Watteen at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
March 1867.
I, EMILE WATTEBU, of Middlesboro'-on-Tees, in the County of York, do
hereby declare the nature of the said Invention for "AN IMPROVED NUT TAPPING
MACHINE," to be as follows:-
This Invention consists of a compound nut tapping machine whereby a
number of nuts may be tapped at one and the same time. The top of the
machine consists of a table which revolves horizontally, and the taps are
worked by appropriate gearing arranged on vertical axes. I purpose that
in one revolution of the top of the machine all the nuts under operation shall
be tapped; this revolution is completed at a certain point, and here each tap
falls through, and the nuts immediately afterwards also drop through an
aperture made purposely in the table.
The machine as I prefer to construct it is arranged for the tapping of
twelve nuts at one and the same time. The main vertical shaft herein-before
called axis is driven from its lower end by toothed gearing connected by
bands or other appropriate machinery with the prime mover. The top of the

page_text: said vertical shaft carries the toothed wheel which gives the rotary motion to
the taps; this is done, however, by an intermediate set of toothed wheels
arranged round the aforesaid toothed wheel, and I prefer to have each wheel
of this intermediate set of such a diameter as to work two taps, thus the
centre toothed wheel will drive six intermediate ones, each one of which will
work two taps or twelve taps in all; the taps have the thread cut to their
points, thereby facilitating their introduction into the nuts, and they are
forced through by their own specific weight. I think it preferable to give
motion to the revolving table by an endless screw, and I secure the nuts
in slots on the under side of the disc or that portion of the revolving table
in which is placed the gearing by which the taps are caused to rotate.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Emile Watteeu in the Great Seal Patent Office on the 23rd
September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EMILE
WATTEEU, of Middlesboro'-on-Tees, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Emile Watteeu, Her special licence that I, the said Emile Watteen, my
executors, administrators, and assigns, or such others as I, the said Emile
Watteen, my 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 "AN IMPROVED NUT TAPPING
MACHINE," upon the condition (amongst others) that I, the said Emile Watteeu,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, 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 date of the. said
Letters Patent.
NOW KNOW YE, that I, the said Emile Watteeu, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement:-
This. Invention consists of a compound nut tapping machine whereby a
number of nuts may be tapped at one and the same time. The top of the
machine consists of a table which revolves horizontally, and the taps are worked
by appropriate gearing arranged on vertical axes; I purpose that in one revolu-
tion of the top of the machine all the nuts under operation shall be tapped; this
revolution is completed at a certain point and here each tap falls through, and
the nuts immediately afterwards also drop through an aperture made purposely
in the table.
The machine as I prefer to construct it is arranged for the tapping of
twelve nuts at one and the same time. The main vertical shaft herein-before
called axis is driven from its lower end by toothed gearing connected by bands
or other appropriate machinery with the prime mover. The top of the said
vertical shaft carries the toothed wheel which gives the rotary motion to the
tops; this is done, however, by an intermediate set of toothed wheels arranged
round the aforesaid toothed wheel, and I prefer to have each wheel of this
intermediate set of such a diameter as to work two taps, thus the centre toothed
wheel will drive six intermediate ones, each one of which will work two taps or
twelve taps in all. The taps have the thread cut to their points, thereby
facilitating their introduction into the nuts, and they are forced through
by their own specific weight. I think it preferable to give motion to the
revolving table by an endless screw, and I secure the nuts in slots on the
under side of the disc or that portion of the revolving table in which is placed
the gearing by which the taps are caused to rotate.
Having thus far described the nature and object of this my said Invention,
I shall now proceed to describe the same more minutely, and in order thereto
reference must be made to the Drawings accompanying this said Specification,
which represent in seven different views the various features of
my Invention
in a manner sufficient to render the entire Invention perfectly intelligible to a
skilled mechanic. Like letters and figures denote similar parts, and generally
the Drawings represent a machine on a scale of three inches to a foot or one
quarter its real size.
In Sheet 1 the left side of Fig. 1 shows a half elevation of the entire
machine, and the right side a half section of the machine on the line B, B, of
Fig. 3, Sheet 2, showing the driving and working gear throughout; Fig. 2 is
a half sectional plan of Fig. 1 on the line D, D.
Fig. 3 on Sheet 2 represents on the right hand a half elevation, and on
the left a half section on the line A, A, of Fig. 4; Fig. 4 represents a half plau

page_text: of the top of the machine, and also a half plan having the top plate marked E
removed.
Fig. 5, Sheet 3 shows the under side of the revolving disc F; Fig. 6 is a
plan of the table; and Fig. 7, a half sectional plan at C, C, of Fig. 3. G is
the cone of driving pulleys to give different speeds to the machine and requires
no further description. It is to be understood that there are two motions in
this machine derived from the same driving power. The one we shall first
refer to is that in which the entire top of the machine I revolves, being driven
by the toothed gearing and worm H, H, &c. The top of the machine thus
revolves slowly over the table K, which has a slot K through which the nuts
and taps drop from the under side of the top revolving table I out of the
recesses in which they are placed to be tapped as soon as that operation is
complete; the under side of the top table I with the recesses is shown in Fig. 5
and marked F; the recesses are marked L, L, &c. The taps and nuts are
collected in the recess in the top of the machine seen in the right hand of
Fig. 1 and marked M, being swept into it by the arms of the table K, Fig. 7.
The other motion is that which has to be imparted to the taps; this is obtained
through the toothed gearing N, N, which communicates motion by a vertical
shaft running through the table I which is made hollow for that purpose to the
toothed gearing P, P¹.
The machine as here represented is constructed to tap twelve nuts at one
and the same time, and each wheel of the intermediate series of toothed
wheels P¹ works two taps; they are arranged round the centre wheel, as
shown in Fig. 4; the wheels P¹ give motion to the outer series of twelve
wheels marked R, R, &c., in the centre of each of which is a hollow into
which the taps T, T, are inserted. This portion of the machine is readily
understood by the inspection of the left-hand side of Fig. 8; the taps being
screwed to their points readily enter the nuts, and are urged forwards by the
screwing action and their own specific weight. In this Figure the S denotes
the nut in the process of being tapped. The table K is constructed in halves
and bolted together, as shown in Fig. 7. The vertical shaft above referred
to, which is denominated V and drives the gearing which gives motion to the
taps rests in a shoe at the bottom marked W. X, X, is the main framing of
the machine.
There are many points of detail in this description of my Invention which I
have not thought it necessary to explain, but they will be readily seen and
understood on referring to the Drawings by any practical person acquainted
with machinery.
The great advantage of this machine is the great economy it effects in time

page_text: and labour. Each revolution of the machine completes the tapping of as many
nuts as there are taps used. In this case I have shown twelve only, but any
other number may be used, and by simply changing the taps any sized hole
may be tapped without altering the machine in the under side of the top
table I seen in Fig. 5 and marked F. Several different sized recesses may be
cut to suit various sized nuts.
I have now fully explained and illustrated my Invention, and consider as
secured to me by Her Majesty's Letters Patent, the right to make, use, exercise,
and vend nut tapping machines constructed substantially as that herein-before
described and exemplified by the Drawings hereto.
In witness whereof, I, the said Emile Watteen, have hereunto set my
hand and seal, this Twentieth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven.
