I, WILLIAM ROBERT MUDD, of 18, Granby Yard, Rutland Street, Leicester,.
Boot and Shoe Machinist, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to machines for burnishing or finishing the edges.
of the soles and heels of boots and shoes the object thereof being the provision of
improved mechanism for operating the burnishing tool.
According to this invention the shaft carrying the burnishing tool is provided
with a stud or projection adapted to work in an approximately spiral groove or
cam-way in a sleeve or tube enclosing part of the shaft before mentioned.
A horizontally reciprocating motion is imparted to the sleeve or tube and the
fact of the projection working in the cam-groove communicates a rocking motion to
the burnishing tool.
The tube or sleeve may be operated through the medium of connecting rods and
a crank or eccentric or cam on the driving shaft or by any other suitable.
mechanism.

COMPLETE SPECIFICATION.
Improvements in or relating to Burnishing or Finishing Machines
employed in the Manufacture of Boots and Shoes.
1, WILLIAM ROBERT MUDD, of 18, Granby Yard, Rutland Street, Leicester,
Boot and Shoe Machinist, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to burnishing or finishing machines employed in the
manufacture of boots and shoes and has for its object to provide improved mechanism
for operating the burnishing tool.
The invention will be understood from the following description in reference to
the accompanying drawing in which
Figure 1 is a side elevation partly in section of a burnishing machine having my
improvements applied thereto.
Figure 2 is a section on the line X X of Figure 1.
Figure 3 is a plan of the sleeve detached to more clearly shew the spiral cam
groove.
Figures 4 and 5 are details.
The burnishing tool A is carried in the usual manner in the free end of an arm A'
secured to a counterweight or block B fixed to the shaft C (having bearings in the
upper end of the pillar or standard D) and from which the burnishing tool receives.
the necessary rocking motion.
According to my invention I impart the requisite rocking motion to the shaft C
carrying the burnishing tool A by mounting on the said shaft a sleeve E or equiva-
lent provided with a spiral groove E' working within which is a sliding block F
connected to the shaft C by means of a pin G.
This pin passes through an opening into the shaft C and is internally screw

opposite side of the shaft, as shewn most clearly in Figure 2, and into the end of the
pin G and is tightened against the collar G2, so that upon a reciprocating motion
being imparted to the sleeve E the sliding block F will travel within the spiral
groove and communicate a rocking motion to the shaft C.
The sleeve E is provided with a tongue or downward extension E2, Figure 2,
moving in contact between two plates H which permit of the adjustment of the
sleeve by releasing and tightening the screws H' passing through the bearing D
The plates H are supported in position by means of pius or prongs H² on the
sides thereof, Figures 1 and 2, and which enter holes in the extension D' of the
bearings D'.
The reciprocating movement of the sleeve E is obtained by forming or attaching
on the end thereof a collar E3 or equivalent connected to a bell crank lever J
through the medium of two link plates J.
The bell crank lever is fulcrummed at K' to a bracket K projecting from the
pillar D and carries in its lower tubular end a sliding block or plunger L,
Figures 4 and 5 connected to a pin M' on a disc M on the driving shaft N from
which the lever J derives its motion.
Other mechanism than that described may be employed to reciprocate the
sleeve E.
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 boot and shoe burnishing machine the combination with the shaft operat-
ing the burnishing tool, of a sleeve such as E and sliding block F constructed and
operating substantially in the manner and for the purpose described and illustrated
in the accompanying drawing.
2. In a boot and shoe burnishing machine the combination with a sleeve such as E,
of one or more links such as J¹ bell crank lever such as J operated by a disc M and
pin M or equivalent means substantially in the manner and for the purpose
described and illustrated in the accompanying drawing.
