Improvements in Means for Turning or Reducing the Inserted Ends
or Tangs of Carriage Wheel Spokes, of Wood Parts of Chairs and
Furniture, and other Articles and Structures.
I WILLIAM EDWIN CARY, Red Bank Spring and Axle Works, Red Bank,
Manchester, in the County of Lancaster, Spring and Axle Manufacturer, do hereby
declare the nature of this Invention to be as follows:-
My said Invention relates to means for turning or reducing the inserted ends of
wooden carriage wheel spokes, chair legs and other articles and parts wherein a
round tang or extension of wood is inserted into a hole bored to receive it and
intended to retain the said tang or extension firmly. Such round tangs or extensions
are usually formed by cutters fixed in a holder which is rotated in a lathe or by a
brace or other suitable appliance. The cutting edges of the cutters are at right angles
to the axis of the tang and the tang is of an uniform diameter throughout-so that
when inserted into the hole it is not always firmly held throughout. According to my
invention I reduce the tang slightly toward the outer end, so that when inserted into the
hole it can be more readily entered and driven home and is more firmly held throughout
its length owing to the slight wedging action obtained. To effect this slight reduction
of the outer end of the tang without extra labour and during the operation of
reducing the tang I apply an additional cutter to the ordinary cutter holder, the
cutting edge of the said additional cutter lying parallel or about parallel with the
axis of the tang and in such a position as will cause it to operate on the tang at
the proper place. When the end of the spoke or other part is subjected to the action
of the cutters the additional cutter which lies behind the usual cutters acts on the
tang at the same time to effect the required reduction. More than one of the said
auxilliary cutters may be used and they might be set at a slight angle so as to produce
a tapered reduction at the nose of the tang. The invention is primarily intended for
the reduction of wooden carriage wheel spoke ends but it may be used in the
construction of all articles and parts of wood in which a round tang is formed to
occupy and fill a corresponding hole.

I WILLIAM EDWIN CARY, Red Bank Spring and Axle Works, Red Bank,
Manchester, in the County of Lancaster, Spring and Axle Manufacturer, 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 and
accompanying drawings :-
My said Invention relates to means for turning or reducing the inserted ends of
wooden carriage wheel spokes, chair legs and other articles and parts wherein a round
tang or extension of wood is inserted into a hole bored to receive it and intended to
retain the said tang or extension firmly. Such round tangs or extensions are usually
formed by cutters fixed in a holder which is rotated in a lathe or by a brace or other
suitable appliance. The cutting edges of the cutters are at right angles to the axis
of the tang and the tang is of an uniform diameter throughout so that when inserted
into the hole it is not always firmly held throughout. According to my invention I
reduce the tang slightly toward the outer end, so that when inserted into the hole it
can be more readily entered and driven home and is more firmly held throughout
its length owing to the slight wedging action obtained. To effect this slight reduction
of the outer end of the tang without extra labour and during the operation of reducing
the tang I apply an additional cutter to the ordinary cutter holder, the cutting edge
of the said additional cutter lying parallel or about parallel with the axis of the tang
and in such a position as will cause it to operate on the tang at the proper place.
When the end of the spoke or other part is subjected to the action of the cutters the
additional cutter which lies behind the usual cutters acts on the tang at the same
time to effect the required reduction. More than one of the said auxilliary cutters
may be used and they might be set at a slight angle so as to produce a tapered reduction
at the nose of the tang. The invention is primarily intended for the reduction of
wooden carriage spoke ends but it may be used in the construction of all articles
and parts of wood in which a round tang is formed to occupy and fill a corresponding
hole.
For the purpose of making my invention more easily understood I have attached
hereto a sheet of drawings illustrating the improvement.
Fig. 1 is a side view of a hollow cutter or auger for reducing and rounding the
ends of spokes and similar objects.
Fig. 2 is an end view of the same.
Fig. 3 is a cross section at A. B Fig. 1.
The tool carrier or body a consists of a hollow sleeve open at the front end and
formed at the other end with a squared tang b to fit either a hand brace or the spindle
of a lathe or tool. At the front end are situated the usual cutters c secured by

page_text: Behind the said
screws d to surfaces e f which are cast in one with the carrier a.
cutters c is situated the additional cutter g which is the subject matter of my present
invention. In using the tool it will be understood that as the tang is reduced by the
cutters cit passes into the interior of the hollow carrier a and is there subjected to a
slight further reduction by the cutter 9 whereby it is tapered to the required extent.
Fig. 3 illustrates very clearly the relative position of the cutter g to the carrier a
upon which it is mounted. A projection is cast upon the carrier a and the cutter g
is secured thereto by a screw i. The cutter passes through a slot in the side of the
carrier and projects sufficiently into the interior to operate upon the tang as it passes
up the hollow carrier. The cutter g may be set to any suitable angle so as to give the
required taper to the end of the tang. Any of the cutters can at any time be removed
for the purpose of sharpening, renewal or re-adjustment. More than one of the
additional back cutters y might be used. The tool illustrated and described is specially
suited for the reduction of carriage wheel spoke ends but it may be used for all articles
requiring to be furnished with a round tapered tang or extension.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1) In a tool for turning and reducing the inserted ends or tangs of carriage wheel
spokes or of parts of furniture and other articles, the additional back cutter or cutters
placed behind the usual or suitable front cutters and employed to taper the reduced
ends or tangs of articles operated upon by the tool, substantially as hereinbefore
described and shewn.
(2) In a tool for the indicated purposes the combination of the cutter g or more than
one such cutter with the cutters c substantially as described and shown.
(3) The cutter g arranged and acting for the purposes and substantially as described
and shown.
