I, FREDERIOK CUTLAN, of Castle Hill, Wellingborough, Northamptonshire 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:-
This invention relates to heel-paring machines and consists in an improved manner
of suspending the tool or knife carrier of such a machine.
In the accompanying drawings ;-
Fig. 1 is an elevation of sufficient of a machine to illustrate the application of my
invention thereto and Fig. 2 is a section on the line a-b of figure 1.
passes
A is the knife holder which may be constructed in the usual manner and to which
the cutter or knife A¹ is secured by a bolt A² and nut A³ the former of which
through a slot in the knife A¹ to admit of the adjustment of the said knife in the
well-known manner. The knife holder A is provided with the two lugs A by means
of which and a pin B¹ the said holder is pivotted to the bracket B which is pivotted
by a pin C to the hanging plate or "quadrant" C. The pivot pins B¹ and C¹ are
disposed in different horizontal planes and in different vertical planes at right angles
to each other so as to constitute virtually a universal joint. The hanging plate is
pivotted by a pin D¹ between the cheeks D2 and D³ of the bar D. The plate C is
provided with two anti-friction rollers C³ which are adapted to bear against the
contiguous face of the cheek D' and which are free to rotate in openings formed
in the plate C in which openings they are retained by means of the pivots on which
they rotate.
By pivotting the plate C near its upper end instead of lower down as has hitherto
been done a greater range of motion along a circular path is provided, and by the
addition of the joint C the equivalent of which has not before been used much
greater freedom of action is also provided so that by these improvements the cutter
or knife when being moved over a heel in the ordinary manner will readily adjust
itself to any inequalities that may be presented to it.

page_text: 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 a tool supporting device for a heel paring machine the combination with the
bar D affording a circular path of the hanging plate or "quadrant" such as C
pivotted near its upper end and provided with anti-friction rollers C³ substantially as
described and illustrated in the accompanying drawings.
2. In a tool supporting device for a heel paring machine the combination with a
pivotted plate such as C and tool holder such as A of a universal joint such as B B¹ A*
and C¹.
3. The complete tool supporting device for a heel-paring machine consisting
essentially of a hanging plate such as C provided with anti-friction rollers such as C
and pivotted in the bar D and having pivotted to it a bracket such as B to which is
pivotted a tool holder such as A substantially as herein described and illustrated in
the accompanying drawings.
Dated this 25th day of April 1889.
