PROVISIONAL SPECIFICATION.
Improvements in Machines for Planing or Shooting Mitres.
I, CHARLES TAYLER Junior, of 8 and 9 Mitre Street, Aldgate, in the City of
London, Picture Frame Maker, do hereby declare the nature of this invention to
be as follows:-
The invention has for its object improvements in machines for planing or
shooting mitres whereby the work is greatly facilitated and accellerated and great
exactness is obtained.
For this purpose I mount in suitable bearings carried by a bench or other
support, a horizontal shaft, on which a driving pulley is keyed at or near the centre
of the length thereof. At each end of said shaft is also keyed a plane carrying
disc, which has cast or otherwise fixed thereon, a bracket or projection, the face of
which is at such an angle with the disc as to support the plane iron at the requisite
angle for cutting. The plane iron is formed with a longitudinal key-hole slot,
through which a screw is passed, which is screwed into the aforesaid bracket or
projection; the back iron is also formed with a similar slot, through which such
screw is also passed, so that the head of the screw shall bear on each side of the
narrow part of the slot and form a fulcrum for said back iron, which latter, near its
back edge, is fitted with a pair of screws, which, by being forced against the face
of the plane iron, cause the front edge of the back iron to bear firmly against the
plane iron at a short distance from its cutting edge.
The plane iron has also fixed in its slot, a block having a transverse groove,
within which enters one end of a lever, which is mounted on an axis carried by
the aforesaid bracket or projection, whilst the other end of such lever is acted upon
by an adjusting screw, so as to regulate with great exactness the extent to which
the edge of the plane iron projects through its slot in the disc.
The bench is fitted with the usual mitreing blocks, which are generally fixed at
an angle of 45 degrees, but which may be fixed at any required angle.
By making the machine with a planing disc at each end of the shaft, facility is
afforded for planing or shooting each end of a moulding with the face thereof
upwards, and when working on flat mouldings, two men could work at the machinė
at the same time.
I would here remark that the means for fixing the plane iron and of adjusting
the extent of projection of the same through the disc, may be varied without
departing from the peculiar character of my invention.

COMPLETE SPECIFICATION.
Improvements in Machines for Planing or Shooting Mitres.
I, CHARLES TAYLER, Junior, of 8 and 9 Mitre Street, Aldgate, in the City
of London, Picture Frame Maker, do hereby declare the nature of this inven
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :—
The invention has for its object improvements in machines for planing or shooting
mitres whereby the work is greatly facilitated and accellerated and great exact-
ness is obtained.

page_text: A nitre planing or shooting machine constructed according to my invention is
illustrated in the accompanying drawings, in which
Figure 1, is a front elevation partly in section,
Figure 2 is an end elevation, and.
Figure 3 is a plan thereof partly in section.
Figure 4 is a plan showing a slightly modified arrangement.
Figure 5 is an underside view of one of the plane irons showing the block used
for adjusting the edge of the plane iron, and
Figure 6 is a top view of the "back iron."
In all the figures like parts are indicated by similar letters of reference.
a
a represents the machine framing, b is a horizontal shaft, which is carried in
bearings a carried by the frame a. This shaft b has fixed at or near the centre of
the length thereof a driving pulley b' by which such shaft can be rotated by
strap or band driven by any suitable motor. In the arrangement shown at
Figures 1, 2, 3 a loose pulley 2 is also mounted on the shaft and a sliding fork c,
mounted in guides a² and operated by crank lever c¹ and link c², is employed to
shift the driving strap from the fast to the loose pulley and vice versa, whilst in the
arrangement shown at Figure 4, the shaft bis provided with only the driving
pulley b', the fixed and loose pulleys and strap shifting gear being arranged in
connection with a suitable driving shaft.
At each end of the shaft b is also keyed a plane carrying disc d, which has cast
or otherwise fixed thercon a bracket or projection d', the face of which is at such
an angle with the disc d as to support the plane iron e at the requisite angle for
cutting.
The plane iron is formed with the usual longitudinal key-hole slot e¹, through
which a screw is passed which is screwed into the bracket or projection d'; the
back iron g is also formed with a key-hole slot g', through which the screw fis
also passed so that its head shall bear on each side of the narrow part of the
slot g¹ and form a fulcrum for said back iron, which latter near its back edge is
fitted with a pair of screws 9² 2, which, by being forced against the face of the
plane iron e, cause the front edge of the back iron g to bear firmly against the plane
iron e at a short distance from its cutting edge.
The plane iron e has also adjustably fixed in its slot el, a block e² having a
transverse groove e within which enters one end of a lever h which is mounted on
an axis h¹ carried by the aforesaid bracket or projection d' whilst the other end of
such lever which is forked enters an annular groove in an adjusting nut
mounted on a screw i, by which means the extent to which the edge of the
plane iron projects through its slot d in the disc d can be regulated with great
exactness.
The machine bench is fitted with the usual mitreing blocks ;; which are
generally fixed at an angle of 45 degrees but which may be fixed at any required
angle.
By making the machine with a planing disc d at each end of the shaft b as shown
in the drawings, facility is afforded for planing or shooting each end of a moulding
with the face thereof upwards, thereby avoiding injury to the face of the moulding,
whilst by the use of the modification shown at Figure 4, and when working on flat
mouldings two men could work at the machine at the same time.
I would here remark that the means for fixing the plane iron e and of adjusting
the extent of projection thereof through the disc d form no part of my invention
and may be varied without departing from the peculiar character thereof.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A mitre planing or shooting machine constructed substantially as herein shown
and described.
2. In a mitre planing or shooting machine the combination with a work supporting

disc fixed on each end of the said shaft, substantially as herein shown and
described. .
