Improvements in Edge Setting and Burnishing Machines.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON, and
SYDNEY ANSELL GLASON all of the firm of Gimson and Company of the Vulcan
Engineering Works, Vulcan Street, Leicester, in the County of Leicester, Engineers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in edge cutting and burnishing machines
used in the manufacture of boots, shoes and the like, and consists of an improved
means of imparting a vibrating motion to the arm carrying the edge setting and
burnishing tool, also in the making of the odge setting irons that the shock
experienced when holding the boot to the burnisher is reduced to a great extent and
the operator may with ease hold the boot to the heated iron or tool for setting the
edges and burnishing boots, shoes, or other foot coverings.
By the present method of having the edge setting iron on the end of an horizontal
oscillating arm in non-automatic edge setting and burnishing machines a great shock
to the whole frame of the operator is experienced which ultimately results in the
operator not having power required in pressing the boot to the setting iron.
Our object is to make a non-automatic machino in which the setting iron can be
adjusted at the lower end of a vertical vibrating arm, and to obviate the jarring we
insert in or on the edge setting and burnishing tool a buffer and spring or its
equivalent, thus enabling the operator to control the necessary pressure required in
holding the boot against the rubbing face of the setting iron.
For this purpose we provide a frame having suitable bearings at the top in which
is placed a horizontal shaft, one end of which carrios a disc having a crank pin therein
the said pin fitting into a block of any desired shape which works in the upper part
of the vibrating arm; when by the revolution of the shaft the upper portion of tho
vibrating arm is moved, the arm being upon a central conical axis, its lower end
vibrates rapidly and gives the left and right movement desired to effect the polishing
and setting of the edges and waist of boots, and the like. The tool is heated from the
underside by a jet of gas, coming from a pipe fitted to the machine.
The vibrating arm is adjusted on its conical axis, by nuts, adjusted so that the
freedom and amount of play necessary without friction is given; the conical pin is
carried through the frame of the machine and fastened securely at the opposite end.
Upon the outer end of the eccentric shaft is placed a small pulley which carries a
small belt passed round a driving pulley fitted on at the end of a small horizontal
shaft-fitted in bearings in an elbow of the frame of the machine and carrying the
necessary fast and loose pulleys in connection with a belt fork. If necessary this
non-automatic machine may work by hand or foot by having a hand wheel or foot
treadle attached thereto.

Improvements in Edge Setting and Burnishing Machines.
We, JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON, and
SYDNEY ANSELL GLSON all of the firm of Gimson and Company of the Engine
Works, Vulcan Street Leicestor, in the county of Leicester, Engineors, do hereby

page_text: performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in edge setting and-burnishing machines.
used in the manufacture of boots, shoes and the like, and consists of improved
means for imparting a vibrating motion to the vertical arm carrying the edge setting !
and burnishing tool.
Also in making the set irons so that the shock or jar experienced when the boot is
held to the burnisher is reduced to a great extent, and the operator is enabled with
greater ease to hold the boot to the heated iron for setting the edges and burnishing
the waist or sole of a boot, shoo or other foot covering.
By the present means employed in non-automatic machines having the set iron on
the end of a vertical oscillating arm a great shock or jarring is felt by the operator
and bad work is generally the result.
Our main object is to make our non-automatic machines so that the edge setting
iron may be adjusted at the lower end of the vibrating arm, or arms, and to provide
either on the shank of the tool, or inside the body of the tool a buffer and spring, or
its equivalent to enable the operator to control the pressure required in holding the
boot against the rubbing face of the setting iron to produce a good set edge.
That our invention may be well understood drawings accompany this specification
to which we will now refer.
Figure 1, sheet 1, is a side view of a single machine consisting of the frame or
pillar A, at the top of which is fitted the short crank shaft B, carried in the bearings 1,
the outer end of the said shaft carrying the pulley C, on the opposite end is the disc D,
with the crank pin E, set therein, the outer end of the said pin fitting in the block F,
which moves in the box or sleeve G, at the upper end of the vibrating arm H, which
is fitted upon the central conical axis 7, the shaft of which goes through the pillar A,
and is secured at the opposite end by the nut 2, the vibrating arm being adjusted by
the nut h³, so that the freedom and amount of play necessary is obtained without
friction, the edge setting tool I, is placed in the lower end of the vibrating arm Ḥ,
and secured by a set pin I, the brackets J, carry the gas pipe K, the nozzle or burnor, I
being turned away from the burnishing tool as shown in Figure 3, while the edge
setting or burnishing is in operation, the pulley C, carries a belt passed round tho
driving pulley M, on the inner end of the driving shaft N, riding in the bearings n¹
attached to the arms n of the frame, the belt fork, O, is secured to the arms n³ and
operated by the handle o' to shift the driving belt not shown on to the loose or fast
pulleys, o³ and o³ each bracket is supplied with a lubricating cup P, containing the
necessary lubricating oil, a well Q is screwed to the side of the pillar A, and
contains ink for blacking the edges of the sole and heel before burnishing.
Figure 2. is a sectional top view of the crank shaft B, and bearings 6' showing
the crank pin E, and block F, in the box G of the vibrating arm H.
Figure 3, is a cut off side view of the frame or pillar A, showing through the box G,
in dotted lines the disc D, and crank pin E, in the vibrating arm H, the dotted lines
drawn through the central axis denote the amount of vibration required to cause
the rubbing of the edge setting or burnishing tool I, fitted in the lower end thereof,
on the boot or shoe when held against it.
Figure 4, is a side view of a burnishing iron, I, of the shape suitable for polishing
the outsoles of boots and shoes, the shank is inserted in the bottom of the vibrating
arm H, and secured therein by the set pin I¹.
Figure 5. is a view of another form of burnisher I, the projecting lip of which fits
against the insole and is used for setting the waist of a boot or shoe.
Figure 6. is a cut-off front view of the lower part of the vibrating.
arm H, the
edge setting iron 1, having a slot I cut therein which fits on to a pin I³ in the shank
upon which is placed the spring I against the buffer I the tool being held by the
free end of the spring 1° coming against the projecting side of the set iron.
Figure 7. is a cut-off side view of the lower part of the vibrating arm H, the
edge setting tool I, being provided with the buffer 1" and spring Iº.

page_text: Figure 8. is a modification of the previous figure showing an angular edge
setting tool 1, the edges of the fore part of the boot being held to the tool at an angle
instead of vertical.
Figure 9. is a front view in elevation of a double, or Twin non-automatic_edge
setting and burnishing machine the short shaft B, having two vibrating arms H, one
at each end thereof, the pulley C, being in this case in the centre of the shaft. Two
persons can be employed on this machine at the same time.
Figure 10. is a side view in elevation of the Twin non-automatic edge setting
and burnishing machine.
The same letters of reference represent like parts in all the figures.
It will be seen by reference to the drawings that the boot or shoe is held by the
operator against the edge setting or burnishing tool I, as shown in figure 1. after
each edge, sole or waist has been burnished the jet of gas is turned round to the
tool that it is heated while another boot is got ready.
By the means shown and described the machines are worked by power but
it will be well understood that they can be worked by hand or foot by having a
hand wheel, or foot treadlo attached thereto.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declaro that what we
claim is:-
1. In a non-automatic odgo setting and burnishing machine whereby the rubbing
and polishing is effected by a tool fixed at the end of a vibrating arm, or arms as
the case may be, the adjustment of the arm or arms upon a central conical axis
in the manner shown and described.
2. In a non-automatic edge setting and burnishing machine of the character
shown and described the means whereby the arms is vibrated by the employment of
the short shaft B, carrying a disc D and crank pin E, working in the block F, and
box G, of the arm or arms H, by the driving mechanism connected therewith as
herein before specified.
3. In a non automatic edge setting and burnishing machine the employment of
the slotted edge setting iron I, the shank of which carries the spring 1 and
buffer 1° or its equivalent to prevent jarring.
