page_text: LETTERS PATENT to Henry Augustus Biertumpfel, of Albany Street,
in the County of Middlesex, and William James Loveday, of
Kennington Road, in the County of Surrey, for the Invention of
if Terunawaarax TN MACHINERY FOR SHADING WOOD AND OTHER MATERIALS.”
Sealed the 28th October 1870, and dated the 16th May 1870.
PROVISIONAL SPECIFICATION left by the said Henry Augustus
Biertumpfel and William James Loveday at the Office of the
Commissioners of Patents, with their Petition, on the 16th May.
1870.
We, HENRY AUGUSTUS BIERTUMPFEL, of Albany Street, in the County
of Middlesex, and WILLIAM JAMES LOVEDAY, of Kennington Road, in
the County of Surrey, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR SHAPING WOOD AND OTHER MATERIALS,”
to be as follows:-
r.
This Invention has for its object improvements in machinery for
shaping wood and other materials, such as iron and ivory, according
to the pattern placed in the mandril and to the set of cutters employed,
and will produce one or more of the said articles at the same time.
We employ for this purpose a long bed with a sliding table to traverse

page_text: •
from one end to the other by means of a screw which is attached to the
sliding table at each end, and is by preference connected by the means
of a nut in two halves for giving motion to the table, a screw with right
and left handed thread causes the two halves of the nut to be drawn
close to or free of the screw, thus connecting or disconnecting the same.
On the top of the table we have a series of mandrils and centres, in the
mandrils are placed the pattern required, and in the centres the material
required to be shaped. Over the top is a swinging frame placed in
centres at one end and having a spindle at the other with fly cutters
driven at the required speed; on this spindle is a roller, working on the
pattern in the first mandril which is set in motion and gives action to
all the others by the application of wheels; in place of a roller we can
use a piece of metal to trace the pattern. The motion given to the
mandrils drives by means of a worm or other wheel the screw for the
table that feeds the work, the speed being regulated by change wheels:
from the mandrils to the screw for whatever feed the work requires ;
after travelling the required distance of pattern the screw is disconnected
by unscrewing the two halves of the nut and the sliding table is brought
back to its first starting point, against a stop, by means of a rack and
pinion by the action of the workman; the finished articles are then :
taken out and other pieces of material put in to recommence the above
operation. The reversing may however also, if desired, be accomplished
by self-acting means.
We claim as a great advantage in working wood having the cutters
cutting with the grain of the wood. The swinging frame which carries 2
the cutters we prefer to place over the work, but it may also if desired
be placed in other positions.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Augustus Biertumpfel and William James
Loveday in the Great Seal Patent Office on the 16th November
1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
AUGUSTUS BIERTUMPFEL of Albany Street, in the County of Middlesex,
and WILLIAM JAMES LOVEDAY, of Kennington Road, in the County of
Surrey, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of May in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
5 give and grant unto us the said Henry Augustus Biertumpfel and
William James Loveday, Her special licence that we, the said Henry
Augustus Biertumpfel and William James Loveday, our executors,
administrators, and assigns, or such others as we, the said Henry
Augustus Biertumpfel and William James Loveday, 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 "IMPROVEMENTS IN
3 MACHINERY FOR SHAPING WOOD AND OTHER MATERIALS," upon the condition
(amongst others) that we, the said Henry Augustus Biertumpfel and
William James Loveday, our executors, or administrators, by an instru-
ment in writing under our or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 we, the said Henry Augustus Biertumpfel
and William James Loveday, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement,
reference being had to the accompanying Drawings, and to the letters
of reference marked thereon, that is to say :-
This Invention has for its object improvements in machinery for
shaping wood, and other materials, such as iron and ivory, according to
the pattern placed in the mandril and to the set of cutters employed,
and will produce one or more of the said articles at the same time. We
employ for this purpose a long bed with a sliding table to traverse from
one end to the other by means of a screw which is attached to the
sliding table at each end, and is by preference connected by the means
of a nut in two halves for giving motion to the table; a screw with
right and left-handed thread causes the two halves of the nut to be
drawn close to or free of the screw, thus connecting or disconnecting

page_text: the same.
On the top of the table we have a series of mandrils
and centres; in one is placed the pattern required, and in the others
the materials required to be shaped; over the top is a swinging frame
placed in centres at one end, and having a spindle at the other, with
fly cutters driven at the required speed; on this spindle is a roller |
working on the pattern in the first mandril, which is set in motion and
gives action to all the others by the application of wheels; in place of a
roller we can use a piece of metal to trace the pattern. The motion
given to the mandrils drives by means of a worm or other wheel the
screw for the table that feeds the work, the speed being regulated by
change wheels from the mandrils to the screw for whatever feed the
work requires; after travelling the required distance of pattern the
sorew is disconnected by unscrewing the two halves of the nut, and the
sliding table is brought back to its first starting point against a stop by
means of a rack and pinion by the action of the workman; the finished:
articles are then taken out and other pieces of material put in to re-
commence the above operation. The reversing may however also, if
desired, be accomplished by self-acting means.
We claim as a great advantage in working wood having the cutters
cutting with the grain of the wood. The swinging frame which carries
the cutters we prefer to place over the work; but it may also, if desired,
be placed in other positions.
And having now described the nature of this Invention we will
proceed to explain the same more fully with reference to the accom-
panying Drawings.
Fig. 1. is a side elevation of a machine constructed according to our
Invention; Fig. 2 is a plan of the same; and Fig. 3 is a cross section.
A is the bed of the machine; B is a sliding table which can traverse
from one end to the other by means of a screw O which runs in bearings
on the table B and works in a nut D on the bed A. This nut is in two
halves which are connected together by a right and left handed screw E
having a hand wheel F. The nut may be connected to or disconnected
from the screw by turning the hand wheel one way or the other, as
required. The table has four mandrils and centres. The pattern which
is to be worked to is held between the centre a and the mandril 6, while
the articles to be shaped like it are held respectively between the centres
a², a³, and a³, and mandrils 6', 6³, and 63. H and H' are two levers, each
swinging on a fulcrum bracket I fixed on the bed. The levers carry
-

page_text: between them a spindle J having a driving pulley K which is caused to
revolve at a suitable speed for the fly cutters L, which have their cutting
edge shaped as the guide roller. The spindle also carries a roller M
which follows the shape of the pattern. The four mandrils are all driven
at exactly the same speed by means of the tooth wheels N, N, N, N. One
of them is driven from the screw spindle C by means of change wheels
O and P. The screw spindle O is again driven by means of bevel wheel
gearing and strap pulley, as shewn. The change wheels may be shifted
as required, according to the speed suitable for various sizes of the work
and the material operated upon. When the table has travelled the
required distance the screw is disconnected by turning the hand wheel F,
and the table is brought back quickly to its starting point by means of
a hand wheel Q, pinion R, and rack S. Instead of making the fulcrum
of the swinging frame stationary, and the table sliding or travelling, the
arrangement may be reversed when required. It will be evident that
when arranged as shewn right and left handed articles may be produced
simultaneously, for instance, right and left handed boot lasts. The
articles may also be made to run the same way by means of intermediate
wheels.
-
And having now described the nature of the said Invention, and in
what manner the same is to be performed, we declare that we claim,-
First. The employment and arrangement of a transverse swinging
frame with cutters which cut in the direction shewn and described.
Second. The arrangement of the disconnecting gear by means of a nut
in two halves and a right and left handed screw, as shewn and described.
Third. The general combination of swinging frame, table, bed, and
disconnecting arrangement, substantially as shewn and described.
In witness whereof, we, the said Henry Augustus Biertumpfel
and William James Loveday, have hereunto set our hands and
seals, this Fourteenth day of November, in the year of our Lord
One thousand eight hundred and seventy.
