COMPLETE SPECIFICATION.
Improvements in Plough and Fillister Planes.
1, WILLIAM KIMBERLEY of Highgate Tool Works, Emily Street, Birmingham
Tool 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 :—
This invention relates to plough and sash fillister planes, the fence or guide-piece
of which is regulable by means of an adjusting box and screw passing transversely
through the body of the plane, the said screw being attached at one end to the fence
and caused to travel to and fro laterally inside such box by rotating in a fixed nut
engaging therewith, there being also sliding guide arms attached to said fence to
ensure parallel action.
My improvements consist (1) in introducing a set screw preferably vertical
worked by a thumb bit, to engage with and fasten the regulating screw in any
desired position, and (2) in forming either a wooden fence with a metal frame or
support or in attaching to an irou fence of the usual kind a face of wood or other
suitable substance said face or front being attached to said fence or back by means
of screws or in any other suitable way.
I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows a perspective view of my improved plough plane with a handle for
working same.
Fig. 2 shows a similar view of a sash fillister without a handle.
Fig. 3 shows a transverse section of the plough through the adjusting-spindle and
nut.
Fig. 4 shows a cross-section of the screw box shewing the method of locking the
regulating screw c, by means of the inset b, the face of which engages with the
thread of the screw c.
a, is the set screw. b, is the inset at lower end of set screw a.
c, is the
regulating screw of the fence. c', is the box in which the regulating screw works.
d, d, are the two guide arms. e, is the metal back of the fence. f, is the face of
wood or other suitable material.
The chief advantages of my improvements are (1) the securing greater exactness
and accuracy in the relative positions of the fence and cutting iron of the plane.
(2) the avoidance of a corrosive metal face to the fence, which is inimical to easy
action, and does not soil or damage the surface of the wood on which it operates
and (3) easy and rapid adjustment of the set screw without injury to the thread of
the regulating screw.
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
I claim is :-
1. In a plough or fillister plane the combination of a regulating screw c, and box
with a set screw a, worked by a thumb bit having a loose inset piece, or other
suitable device said set screw penetrating said box and engaging with and fixing
said regulating screw in any desired position as herein described and set forth.

page_text: 2. In a plough or fillister plane the combination therewith of a metal fence with
face of wood or other suitable material or a wooden fence strengthened and
supported by a metal frame as herein described and set forth.
