AN IMPROVED SCREWING AND TAPPING MACHINE
Year: 1865

page_text: LETTERS PATENT to Emile Watteen, of Middlesboro-on-Tees, in the
County of York, for the Invention of "AN IMPROVED SCREWING AND TAPPING
MACHINE."
PROVISIONAL SPECIFICATION left by the said Emile Watteen at the
Office of the Commissioners of Patents, with his Petition, on the 9th
December 1865.
I, EMILE WATTEEU, of Middlesboro-on-Tees, in the County of York, do
hereby declare the nature of the said Invention for "AN IMPROVED SCREWING
AND TAPPING MACHINE," to be as follows:-
This Invention consists of a compound rotrary machine whereby several
bolts or nuts may be screwed or tapped at the same time, and each being if
needed of a different diameter. The motion may be derived from a horizontal
shaft, but by preference a vertical one is used, such shaft being driven by a
steam engine or other primum mobile. This vertical shaft rests in a bush of
suitable metal on one end, and is supported in its position by passing through
a revolving table which moves in a V-joint on the bed plate of the machine.
By means of a bolt it can be clamped in any required position. To the
vertical or horizontal shaft already mentioned is keyed a toothed wheel, which
gears into as many spur pinions or friction sheaves round its circumference as
may be required, each of which gives motion by means of mitre wheels to a

page_text: spindle at right angles thereto. The end or ends of such spindle or spindles
are hollowed out to receive the head of a bolt or nut. The taps and dies are
urged forward by a rack or such other means as are usually employed in such
machines, the frame whereby they are carried being bolted or otherwise
secured to the revolving table before mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Emile Watteeu in the Great Seal Patent Office on the 9th
June 1866.
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 Ninth day of December, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth 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 Watteeu,
my executors, administrators, and assigns, or such others as I, the said
Emile Watteeu, 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 rend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED SCREWING
AND 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 per-
formed, to be particularly described and ascertained in and by the following
statement:
This Invention consists of a compound rotary machine whereby several
bolts or nuts may be screwed or tapped at the same time, and each being if
needed of a different diameter. The motion may be derived from a horizontal
shaft, but by preference a vertical one is used, such shaft being driven by a

page_text: team engine or other primium mobile. This vertical shaft rests in a bush
of suitable metal on one end, and is supported in its position by passing through
a revolving table which moves in a V-joint on the bed plate of the machine.
By means of a bolt it can be clamped in any required position. To the
vertical or horizontal already mentioned is keyed a toothed wheel, which gears
into as many spur pinions or friction sheaves round its circumference as may
be required, each of which gives motion by means of mitre wheels to a spindle
at right angles thereto. The end or ends of such spindle or spindles are
hollowed out to receive the head of a bolt or nut. The taps and dies are
urged forward by a rack or such other means as are usually employed in such
machines, the frame whereby they are carried being bolted or otherwise
secured to the revolving table before mentioned.
Having thus far explained the nature and object of my said Invention, I
shall now proceed to describe the same more particularly, and that I may do
so as effectually as possible I shall make reference to the accompanying Sheet of
Drawings, and to the letters and figures marked thereon respectively as follows,
like letters and figures denoting similar parts.
Fig. 1 exhibits a plan of my compound rotary screwing and tapping
machine, and Fig. 2 a part elevation and section of the same; A is the vertical
shaft which derives its motion from a steam engine or other primium mobile.
The speed of this shaft may be regulated by cog wheels or friction sheaves, as
shown at C, C, D, D¹, placed for convenience under the table of the machine.
The shaft A rests in a bearing B at the sole, which must be securely placed
in a plumber block and bolted to the main framing, as shown in Fig. 2. The
shaft A is supported by passing through the table E, E, which carries the
apparatus herein-after described, said table being capable of being moved in
the V-joint F in the bed plate G, G, &c. On the shaft A is keyed the wheel
H, which gears into as many spur pinions or friction sheaves I, I, I, &c., as
may be required. The wheels I, I, &c., are carried in bosses K, K, &c., at
the extremities of the arms L, L, &c., which form a portion of the revolving
table E, E. The wheels I, I, give motion by mitre wheels M, M, to the
shafts O, O, which carries the mitre wheels N, N¹, for reversing the motion
thereof, by means of the reversing jaws P and the lever Q. The shafts O, O,
revolve in bosses R, S, formed on the revolving table as shown. The exterior
end of the shafts O, O, are hollowed to receive the bead of a bolt to be
secured by the dies carried in the usual manner by the ordinary apparatus
shown at T, or to receive the end of a tap while the nut to be tapped is carried
at T. The apparatus T is carried on a tray V bolted as shown to the outside
edge of the revolving table E. Y is a tube to convey the oil fro:n the tray V

page_text: into the gutter Z. The action of the machine must be apparent from th
Drawing and description herein given, and it is evident that as many bolts
may be screwed or nuts tapped as there are places for operation, four or six
are convenient numbers, as they may be made advantageously distributed
around the circle.
Having now completely described the nature and object of my Invention,
together with the best means I am acquainted with for carrying the same into
effect, I wish it to be clearly understood that I do not confine myself to the
precise forms, dimensions, or details herein-before described; not do I claim
the absolute use of a vertical shaft A, for a horizontal shaft may be used and
also found more suitable in certain circumstances; what I claim as my Inven-
tion to be secured to me by Her Majesty's Letters Patent is, the general
arrangement and construction of an improved screwing and tapping machine,
substantially as herein-before described, illustrated, or referred to.
In witness whereof, I, the said Emile Wattceu, have hereunto set my
hand and seal, this Seventh day of June, in the year of our Lord One
thousand eight hundred and sixty-six.
Witness,
J. GEO. ASKEN,
Middlesbro-on-Tees.
EMILE WATTEEU. (L.S.)
