PROVISIONAL SPECIFICATION.
Improvements in or relating to Burnishing Machines used in the
Manufacture of Boots and Shoes.
We, WILLIAM ROBERT MUDD and ALFRED POCHIN of Newarke Street,
Leicester, Engineers to the Boot and Shoe Trade, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to improvements in burnishing machines employed
in the manufacture of boots and shoes, and embodies means which have essentially
for their object to impart the necessary rocking motion to the shaft carrying the
burnishing tool, such means being especially applicable for operating the said
rocking shafts upon two or more machines simultaneously.
When such mechanism is employed for multiple machines the latter are placed
preferably back to back and the ends of the rocking shafts carry thereon pinions
which engage the teeth of a double quadrant or equivalent or other mechanism
mounted on a shaft having bearings on the column or standards and located between
the machines.
The quadrant is operated by suitable mechanism from the driving shaft which
may consist of an. adjustable connecting rod attached eccentrically to a disc or
otherwise on the main shaft.

COMPLETE SPECIFICATION.
Improvements in or relating to Burnishing Machines used in the
Manufacture of Boots and Shoes.
We, WILLIAM ROBERT MUDD and ALFRED POCHIN of Newarke Street,
Leicester, Engineers to the Boot and Shoe Trade, do hereby declare the nature of
this invention, and what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has reference to improvements in burnishing machines employed
in the manufacture of boots and shoes, and embodies means which have essentially
for their object to impart the necessary rocking motion to the shaft carrying the
burnishing tool, such means being especially applicable for operating the said
rocking shafts upon two or more machines simultaneously.
When such mechanism is employed.for multiple machines the latter are placed
preferably back to back and the ends of the rocking shafts carry thereon pinions
which engage the teeth of a double quadrant or equivalent or other mechanism
mounted on a shaft having bearings on the column or standards and located between
the machines.
The quadrant is operated by suitable mechanism from the driving shaft which
may consist of an adjustable connecting rod attached eccentrically to a disc or
otherwise on the main shaft.
The invention will be understood from the following description and by reference
to the accompanying drawings wherein
Figure 1 is a front elevation of our invention applied to a twin burnishing
machine only so much of the latter being shewn as is necessary to illustrate the
invention.

page_text: Figure 3 is a back elevation of the principal parts of the mechanism constituting
the invention, and
Figure 4 is a plan on the line X X.
Similar letters of reference indicate the same parts throughout the drawings.
The construction and operation of burnishing machines are well known and
understood in the trade, so that the following description will be limited as far as
possible to those parts of the machine constituting or closely connected with the
invention.
A. A represent the standards or columns of two burnishing machines which are
placed back to back thus constituting what is known as a twin burnishing machine.
B B are the usual rocking shafts, carrying the burnishing tools (not shewn in the
drawings) and mounted in bearings C' C in a plate C'extending over the upper
parts of the standards A A.
The usual rocking or oscillating motion of the shafts B B is effected by bevel
pinions B B thereon engaging the teeth of and being operated by a double
toothed quadrant D provided with bearings E El in the plate C.
The motion of the double quadrant D is obtained through the medium of a
connecting rod F eccentrically fixed to a disc G on the driving shaft H carrying
also the fixed and loose pullies J J.
The connecting rod F is attached to the disc G by a bolt K passing through a
slot in its flattened lower end, through the disc G and having a nut K¹ on one
end and a bolt M and washer M₁ on the other end.
A block L is inserted within the slot F1 and has one end rounded to form a
bearing for the bolt K while the opposite end is in contact with the end of a screw
bolt N passing through the head of the connecting rod and which may be tightened
to take up the wear on the end of the block L.
The connecting rod is also similarly attached at its upper end to the double
quadrant D the stroke of which may be increased or decreased by moving the
end of the connecting rod in the slot D' farther from or nearer to the working
upper
centre of the double quadrant.
It is obvious that by continuing the shaft D' longitudinally and placing thereon
another double quadrant such as D, two other burnishing machines may be operated
and driven by the same power.
Although we prefer to use the double quadrant for the purpose of imparting the
requisite oscillating motion to the tool carrying shaft, yet we may employ a complete
or mutilated tooth wheel in substitution thereof if desired.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In multiple burnishing machines the combination with the tool carrying shafts of
double toothed quadrant such as D or equivalent operated by a connecting rod F
and disc G on the driving shaft or equivalent mechanism substantially as described.
and illustrated in the accompanying drawings.
