PROVISIONAL SPECIFICATION.
Improvements in Edge Setting Machines for Boots and Shoes.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford,
Engineer do hereby declare the nature of this invention to be as follows:-
I mount the edge setting iron in the lower end of a pendulum the upper end
of which is suspended from a pivot in some fixed part of the machine frame.
At some point between the "iron" and the pivot but preferably nearer to the
"iron" I apply a crank or eccentric to the pendulum which engages the same by
means of a die working in a slot.
The crank or eccentric as the case may be is conveniently formed upon the end
of a shaft carried in suitable bearings in the machine frame and when revolved by
a belt or other convenient means imparts to the pendulum and edge setting iron
a to and fro vibrating movement which is utilized for setting the edges of boots
and shoes.
To balance the pendulum for the purpose of reducing the vibration imparted
to the machine frame I employ another pendulum or a reciprocating weight which
is actuated by another crank or eccentric opposite the one previously described in
such a way that equivalent weights are caused to move similarly but in opposite
directions.

Improvements in Edge Setting Machines for Boots and Shoes.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford,
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 :-
The object of this invention is to improve the construction of edge setting
machines by causing the edge setting "iron" to move in a path more closely
approximating to a straight line than has hitherto been the case also in reducing
the number of joints between the driving shaft and the "iron" and also in
balancing the action of the machine which produces the vibrating movement of
the "iron."
This accomplish by constructing the machine head in the manner shewn by
the accompanying drawings in which :-
Fig. 1. is a side view of one form of my invention shewing a double head-that
is constructed to do two boots at one time—and having the right hand head shewn
in section.
Fig. 2. is a front view of the same.
Fig. 3. is a vertical section and Fig. 4. a front view of a head with a balanced
action.
Fig. 5. is a horizontal section on line A. B.
Fig. 6. is a side view shewing another construction

page_text: Fig. 7. is a front view of the same.
Fig. 8. is a sectional plan of the same on line C. D.
I mount the edge setting "iron " a, which may be either single cr double, in the
lower end of a pendulous bar 6 the upper end c of which is suspended from a pivot d
in the frame e of the machine.
At a point between the "iron" a and the pivot d, and as near as convenient to
the "iron," I apply a crank f to the pendulous bar 6 which engages the same by
means of a die g working in a slot h formed in the pendulous bar b.
The crank fis conveniently formed upon the end of a shaft i carried in bearings j.j.
and revolved by a belt k and pulley l.
"
"
The distance from the " iron a to the pivot d being comparatively long and
the arc described by the "iron" a very short causes the "iron to move almost
in a straight line and as there is only the die g intervening between the crank f
and the slot of the pendulous bar & the wear and lost motion are reduced to a
minimum.
To balance the pendulous bar b for the purpose of reducing the vibration
imparted to the machine frame e I may employ a reciprocating weight (Figs. 3.
4 and 5) which is actuated by another crank f₁ formed opposite to and on the
same end of the shaft i as the crank falready described. If desired this weight b
instead of being suspended from the pivot d may vibrate to and fro in a short
horizontal slide attached to the frame e.
When one pendulous bar is balanced by another exactly similar to itself the
construction may be as shewn in Figs. 6. 7 and 8.
The edge setting "irons" a' are mounted in the lower ends of the pendulous
bars the upper ends c' c² of which are suspended from the pivots did in the
frame e' of the machine.
At some point between the "iron" a' and the pivot d' I apply a crank f2 by
means of a connecting rod 92 and pin h² to operate the pendulous bar 62 and an
opposite crank by means of a rod 9 and pin h³ to operate the pendulous bar b
in such a way that the two pendulous bars are caused to move similarly but in
opposite directions.
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
In a machine for setting the edges of boots and shoes :—
1. Mounting the edge setting "iron" in the lower end of a pendulous bar the
upper end of which is suspended from a fixed point and operating it at a point
between the "iron" and the point of suspension, substantially as described.
2. Balancing the pendulous bar which carries an edge setting "iron" by means
of a reciprocating weight similarly mounted and operated, the two nioving in opposite
directions, substantially as described.
3. Forming two cranks or eccentrics on opposite sides and at the same end of a
motor shaft for the purpose of imparting a balanced movement to two pendulous
bars either or both of which may carry edge setting "irons," substantially as
described.
4. The edge setting machine head constructed and operated in either of the
ways herein described and illustrated and for the purpose specified.
Dated this 23rd day of December 1895.
