Improvements in Apparatus for the Manufacture of Balusters and
Newel Posts, Table Legs, or similar Work in which the
Appearance of a Square Section at any Part is Required.
1, CUTHBERT MARR, of 52 Bele Burn Road Jarrow, in the County of Durham,
Mahogany Merchant &c., do hereby declare the nature of this invention to be as
follows:-
The ordinary method of manufacturing balusters, newel posts, table legs or
similar work, such as it is the object of my invention more simply and perfectly to
manufacture is as follows.
The posts are arranged upon a wheel of considerable diameter side by side, and
being set in lines as nearly as may be paralel with the shaft on which the wheel
revolves they are firmly held in position by means of two straps of iron or steel or
other convenient material which embrace the whole of them, and press them firmly
against the wheel, being then tightened by screws or other device the wheel may
be turned so as to act like a turning lathe and the whole may be trued up by a
turning tool so as to present (owing to the large diameter of the wheel) an
approximately straight surface. The straps are then slackened and the posts or
balusters are each turned so as to present another surface to the cutting tool, and
a second side is dressed and so on until all the sides are finished. Now I by my
invention accomplish the object in an improved manner. I employ the same
description of wheel, but I dispense with the straps the use of which in setting the
work is both troublesome and inconvenient.
Instead of the straps I have 12 or any convenient number of bolts secured to
the centre of the wheel, at each side, which bolts at their outer ends are screwed
so as to take tightening nuts; and I have a series of segments curved internally as

segment can be fitted on to each bolt, so that when they are all in position they
embrace the circumference of the wheel over the newel posts or balusters which it
is desired to shape, and they hold such posts or balusters securely in position just
as the strap before described would do.
By this improved arrangement I can in the first place more readily secure
paralelism of the posts or balusters with each other and with the centres of the
wheel the radiating bolts serving as guides for the purpose.
Secondly I secure greater facility in changing the position of the work where a
change is required, loosening only at one time those parts which are unler one pair
of segments.
Thirdly can with greater convenience turn a small number of posts when it is
so desired.

segments so as to take up any slight inequalities in the rough wood if desired, or
1 may use springs like carriage springs for segments, so as to produce more
uniform pressure on each piece of work to be operated upon or both combined, but
these devices are not an essential part of my invention.

1, CUTHBERT MARR, of 52 Bede Burn Road, Jarrow, in the County of
Durham Mahogany Merchant &c., 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 ordinary method of manufacturing balusters, newel posts, table legs or
similar work, such as it is the object of my invention more simply, and perfectly
to manufacture is as follows:-
The posts are arranged upon a wheel of considerable diameter side by side, and
being set in lines as nearly as may be paralel with the shaft on which the wheel
revolves they are firmly held in position by means of two straps of iron or steel or
other convenient material which embrace the whole of them, and press them firmly
against the wheel being then tightenel by screws or other device the wheel may
be turned so as to act like a turning lathe, and the whole may be trued up by a
turning tool so as to present (owing to the large diameter of the wheel) an
approximately straight surface. The straps are then slackened and the posts or
balusters are each turned so as to present another surface to the cutting tool, and
a second side is dressed and so on until all the sides are finished. Now I by my
invention accomplish the object in an improved manner. I employ the same
description of wheel, but I dispense with the straps the use of which in setting
the work is both troublesome and inconvenient.
Instead of the straps I have 12 or any convenient number of bolts secured to
the centre of the wheel, at each side, which bolts at their outer ends are secured
so as to take tightening nuts, and I have a series of segments curved internally as
segments of a large circle, the centre of which is the centre of the wheel. One
segment can be fitted on to each bolt so that when they are all in position they
embrace the circumference of the wheel over the newel posts or balusters which it
is desired to shape, and they hold such posts or balusters securely in position just
as the strap before described would do.
By this improved arrangement 1 can in the first place more readily secure
paralelism of the posts or balusters with each other and with the centres of the
wheel the radiating bolts serving as guides for the purpose.
Secondly I secure greater facility in changing the position of the work where a
change is required, loosening only at one time those parts which are under one pair
of segments.
Thirdly I can with greater convenience turn a small number of posts when it is
so desired.
I may use a lining of india rubber or other suitable material within my segments
so as to take up any slight inequalities in the rough wood if desired, or I may use
springs like carriage springs for segments, so as to produce more uniform pressure
on each piece of work to be operated upon or both combined, but these devices are
not an essential part of my invention.
In the drawing hereto attached A. A. represents what I have called the wheel
wherein for clearness I have shewn 6 segments with balusters in them, and
6 segments empty. This is merely shewn thus for clearness-ordinarily I prefer to
fill the whole wheel with balusters. B. B. are what I have called segments, and
C. C. the bolts before described which pass through the segments, and serve by
means of the nuts shewn to brace the segments firmly against the balusters and the
latter against the wheel and so to hold them in position.

page_text: One, two or more bolts may be used in each end of each of the segments and
manifestly they may be variously arranged. And the segments may be made
entirely removable from the wheel, or they may be shifted round upon the bolt so
as to take a position parallel to the axis of the wheel or they may be hinged near
the circumference of the wheel so as to fold back out of the way of the balusters
such modifications not being essential features of my invention.
I usually trim all the balusters square at one end as a preliminary to turning
them and I construct a flange on one side of the wheel against which the trimmed
end of the baluster abuts so as that in all positions if exactly parallel to the axis
of the wheel the turning will exactly correspond on each side.
The parallelism with the axis of the wheel is secured by the squareness and
uniform size of each baluster, and the fixed position of the bolts; or in the case
of the segments being hinged by a suitable guide piece on each segment.
Instead of using india rubber for the inside of the segments I may employ a
number of small pins screwed into the inside surface of the segment or
roughen the inside as the footstep of a stirrup iron is roughened.
may
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
The use of segments substantially as described in wheels for the production of
approximately square balusters or newel posts instead of straps or other device as
heretofore employed for that purpose.
