IMPROVEMENTS TO THE TOOL KNOWN AS A JOINERS PLOUGH AND COMBINING THEREWITH THE TOOLS KNOWN AS SASH AND SIDE FILLISTERS
Year: 1884

page_text: I CALEB CRISFORD of No 7, Ceylon Place Eastbourne Builder do hereby declare
the nature of my invention for IMPROVEMENTS TO THE TOOL KNOWN AS A
JOINERS PLOUGH AND COMBINING THEREWITH THE TOOLS KNOWN AS SASH AND
SIDE FILLISTERS to be as follows:-
.
To the ordinary Joiners plough there is added a moveable metal sole with
cutting teeth and the fence is adjusted by means of a spindle, cog wheels and
thumbscrew instead of in the ordinary way.
This plough is convertible into either a Sash Fillister or Side Fillister by
removing the above mentioned metal sole and substituting in its place another
metal sole with cutting teeth which is also adjustible by the same arrangement
which adjusts the fence of the improved plough.
COMPLETE SPECIFICATION.
I CALEB CRISFORD of No 7, Ceylon Place Eastbourne Sussex Builder do hereby
declare the nature of my invention for IMPROVEMENTS IN THE TOOL KNOWN AS A
JOINER'S PLOUGH, AND COMBINING THERE WITH THE TOOLS KNOWN AS SASH AND SIDE
FILLISTERS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The improvements consist of another method of shifting the fence of the plough
on its arms by means of cogged wheels attached to a spindle extending the whole
length of the body of the plough with corresponding cogged bars which are let into
the arms and the motion for adjustment is obtained by a thumb piece on the end
of the spindle and the fence when adjusted is fixed by the ordinary wedges. The
slide of the stop of the plough is inserted a little nearer the top of the body of the

page_text: plough in order to give room for the spindle before mentioned. The plough also
has a set of moveable metal soles corresponding in size to each of the plough irons
each sole being fitted with two cutting teeth and fixed by a screw on to the body
of the plough. The plough is also convertible into a Sash and Side Fillister. For
the Sash Fillister there is an additional iron sole attached by screws to the body
of the plough and fitted with cutting teeth. For the Side Fillister there is attached
to the fence of the Plough an additional metal fence moveable so as to be brought
immediately under and upon the sole of the Sash Fillister and adjustable to any
width of rebate by means of slots guided and fixed by screws the entire fence
(whether for the Plough Sash Fillister or Side Fillister) being adjustable by the
cogged movement before described. The depth of rebate is ruled by means of
a metal Stop sliding in a slot and fixed by a Screw but attached to and forming a
part of the iron sole before described.
By referring to the accompanying drawings the special features of my invention
will be understood more clearly.
Fig. 1 is an end view of a plough with its body shown in section for the purpose
of explaining my method of giving paralel adjustment to the guide bars, the details
of which movement are also shown in Fig 2.
A. A. are the two cogged bars B. B. are the pinions fixed upon the spindle C.
which extends the whole length of the body of the Plough, D being the thumb
piece by which the spindle is turned.
Figs 3 and 4 represent the Plough fitted as a sash and side fillister.
In the Sash Fillister F is the additional iron sole attached by screws G. G. to
the body of the plough, this also being fitted with cutting teeth H, H. previously
described.
In the Side Fillester K is the additional metal fence shown in all the figures and
in plan at fig. 5 slotted and fitted with screws for adjustment.
L is the metal stop shown in figs 3 and 4 regulated by the screw M to whatever
depth of rebate may be required.
An ordinary Plough would be in no way effected by the metal attachment
forming the fillister herein specified but could be fitted with the same and removed
therefrom at pleasure.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
1 claim is
1st The improved means of adjusting the fence in the plough as hereinbefore
.described and illustrated in the drawings.
2. The addition of the metal soles to the plough as described.
3. The method of converting the plough into Sash and Side Fillisters as described
and illustrated in the drawings.
