Improvements in Wood Tenoning Machines.
I, JOHN HALL of Lea Hurst The Park, in the Town and County of the Town of
Nottingham Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to wood tenoning machines. Upon the bed of a tenoning
machine is usually affixed a frame supporting the cutter blocks necessary for the
tenoning of one end of the wood only, and by moving a loose fence to which the
wood is attached on parallel guides at right angles to the cutter spindles one end of
the piece of wood is tenoned, it being then necessary to reverse the position of the
wood to tenon the other end of it.
My improvements consist in constructing t

Improvements in Wood Tenoning Machines.
JOHN HALL Lea Hurst Fishpond. Drive The Park Nottingham Engineer 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:-
My invention relates to wood tenoning machines. Upon the bed of a tenoning
machine is usually affixed a frame supporting the cutter blocks necessary for the
tenoning of one end of the wood only, and by moving a loose fence to which the
wood is attached on parallel guides at right angles to the cutter spindles one end
of the piece of wood is tenoned it being then necessary to reverse the position of
the wood to tenon the other end of it.
My improvements consist in constructing the loose moveable fence with double
ends connected together by an expanding parallel lattice consisting of a series of
jointed rods connected at each end to the moveable fences by which means the
moveable fences can be expanded or contracted as required and still remain parallel
I have an additional moveable frame fixed upon the bed of the machine for carrying
the necessary extra cutter spindles for tenouing both ends of the piece of wood at
the same time.
Having fixed the additional moveable frame carrying the extra cutter spindles

page_text: for tenoning both ends of the piece of wood at the same time the required distance
from the stationary one and at the same time contracted or expanded the moveable
fences and parallel lattice to their correct positions and fixing the same by means
of bolts and nuts, I fasten the piece of wood requiring to be tenoned at both ends
to the moveable fence and pass it between the two sets of revolving cutter spindles
and thus tenoning both ends of the piece of wood to the required distance between
the two shoulders of the tenons at each end of the piece of wood by one movement
past the cutter spindles. But in order that my invention may be the better under-
stood and readily carried into effect, I will by the aid of the drawings annexed
proceed to describe means pursued by me in carrying the same into effect.
In each of the figures the same letters are employed to indicate corresponding
parts.
to
Fig. 1 represents a front elevation and Fig. 2 a plan of tenoning machine. The
driving shaft S, supported at the back of the machine on bearings S to drive the whole
of the cutter spinules is provided with driving drums S2 and S3 the drum S³ is formed
of sufficient length to enable the frame /. to be traversed its full extent either inwards
or outwards as shewn at Fig. 2. the pulley t. is provided with one cross strap and
one open strap in order that the pulley t placed between two loose pulleys may be
driven when required in either direction, and working with the wheels ³ ³ con-
nected to the screw u and nut affixed on the frame h. causes the frame
traverse along the bed A and may be adjusted to its correct position by means of
the hand wheel v carried in bearings and formed to slide with key on grooved
shaft connected to the wheels t² 3, before the frame 1, is fixed for work on the
bed A by means of the bolts and nuts . Upon the bed A is usually affixed a
frame. Supporting the cutter blocks c, c¹ and revolving cutters d, d¹ affixed on
the cutter spindles E, E¹ for tenoning one end of the wood only. A standard f
affixed on the frame b, supports one end of a moveable fence g. On the other end
of the machine bed AI place an additional frame, supporting the extra cutter
blocks, and revolving cutters j, j affixed on the cutter spindles k, k', for tenoning
both ends of the wood at the same time, and on which is also affixed a standard
for carrying the other end of the moveable fence g', these fences are held parallel
to each other at right angles to the revolving cutter spindles E, E' and k, k¹ by a
lattice m. capable of being contracted or expanded as required. I form the lattice m.
of a series of jointed rods m¹ the end centre joints n, n' are affixed to the moveable
fences. the end outer joints o. o' and p p are formed to move in slots outwards
when the lattice is contracted and inwards when expanded as shewn at Fig. 2.
The wood requiring to be tenoned at both ends being fixed on the moveable
fences and passed between the revolving cutters d. d and j. j' and thus both
ends of the wood is tenoned as required by one movement past the revolving cutters,
in place of being reversed end for end in the usual manner on machines having
only one sett of cutter heads.
g.
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
Firstly) The application and adaptation of a lattice by which the moveable fences
are retained in a parallel line at any position of the moveable framing, carrying the
additional set of cutter heads substantially as described and illustrated in the
drawings annexed.
Secondly) The application of a moveable framing carrying the additional cutter
heads by which means both ends of the piece of wood is tenoned at one time sub-
stantially as described and illustrated in the drawings annexed.
