PROVISIONAL SPECIFICATION.
New or Improved Machinery for Cutting Mortices.
I, Alfred SLATER of Horton Lawn Gloucester in the County of Gloucester
Manager to The Gloucester Railway Carriage & Wagon Company Limited do
hereby declare the nature of this invention to be as follows:-
My invention consists of a machine or apparatus capable of being driven by
power by means of which mortices can be simultaneously cut in a ready and
economical way. The machine or apparatus is more especially applicable to the
cutting of mortices in timber.
The cutting tools, can be adjusted to any required distance apart, and have
rotating motion imparted to them so that they cut simultaneously into the timber
or material in which the mortices are to be formed. The said tools are carried by
spindles working in a sliding headstock worked by eccentric or other motion and
provided with an automatic feed arrangement and with adjustable stops. The tools
are connected with the driving gear by compound universal joint spindles and the
machine is provided with a bed and grip or grips for holding the timber or material
to be operated upon.

1 ALFRED SLATER of Hortou Lawn Gloucester, in the County of Gloucester
Manager to The Gloucester Railway Carriage and Wagon Company Limited, 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 consists of a machine or apparatus capable of being driven by
power by means of which mortices can be simultaneously cut in a ready and
economical way. The machine or apparatus is more especially applicable to the
cutting of mortices in timber.
The cutting tools can be adjusted to any required distance apart and have
rotating motion imparted to them so that they cut simultaneously into the timber
or material in which the mortices are to be formed. The said tools are carried by
spindles working in a sliding headstock worked by eccentric or other similar motion
and provided with an automatic feed arrangement and with adjustable stops. The
tools are connected with the driving gear by compound universal joint spindles and
the machine is provided with a bed and grip or grips for holding the timber or
material to be operated upon.
The accompanying drawings illustrate a machine constructed according to my
invention. Figure 1 is a front elevation, Figure 2 an end elevation, and Figure 3
a plan of the aforesaid machine, all the figures being partly in section.

page_text: The timber or material to be operated upon is placed on the adjustable table L which
is provided with anti-friction rollers n and is bolted to the back stop N; the
timber or material being gripped by the jaw M operated by the hand wheel and
screw m.
The cutting tools A A (of which there are two or more) are carried by spindles
mounted in bearings B capable of vertical adjustment to any required distance
apart in the headstock C by screw or other means, they being secured in their
adjusted position by bolts b.
The crank disc D and rod D2 (capable of adjustment as to length of stroke)
gives motion from the shaft H to the saddle E sliding on its bed plate. The said
saddle E carries the headstock C and is provided with a feeding screw f which can
be worked automatically by the feed gear F or by hand by the handwheel G and
gear as shown, a clutch gear 9 with handle g being provided to throw the
automatic gear F out of action when the feed is to be worked by hand.
The headstock C is provided with variable stop for regulating the depth of
mortice and it may also be provided with an indicator to show depth of mortice cut.
The tools AA are connected with the driving gear by sleeves P with compound
universal joints which allow of the vertical adjustment of the spindles and tools of
the sliding motion of headstock C and of the longitudinal traverse for the feed of
the tools.
A single belt h drives the tools, it passing round the pulleys k and also round the
jockey pulley as shewn.
The shaft H driven from any suitable source of power is arranged to drive the
two parts of the machine at their respective speeds, the fast pulleys c and the loose
pulley d being for the cutters and the fast and loose pulleys ee being for the
traverse of the headstock C carrying the cutters.
A belt shifter moving both driving belts simultaneously is also provided.
The mechanisms which I have not particularly described may be of any suitable
or known kind to give the requisite adjustments and movements.
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 machinery for cutting mortices the combination of cutting tools with means
for adjusting them to varying distances apart and means for rotating them and
feeding them so that they act simultaneously upon the work the said tools being
connected with the driving gear substantially as and for the purpose hereinbefore
described.
2. The arrangement and combination of parts constituting a machine for cutting
mortices substantially as hereinbefore described and illustrated in the accompanying
drawings.
