COMPLETE SPECIFICATION.
An Improved Machine for Welt and Edge Finishing in Bootmaking
and like purposes.
I, HEINRICH RAAB, of 39, Alleestrasse, Pirmasens, Rhine Palatinate, in the
Empire of Germany, Machine Manufacturer, 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 boot or shoe making and its object is to provide a
machine for finishing or burnishing the boot welts and edges or like purposes
that is to say the machine serves for the mechanical production of a polished
surface on the blank edges of the soles, wax being employed to assist as is usual.
The means adopted to carry the invention into effect are illustrated in the
accompanying sheet of drawings as follows:-
Figure 1 is a side elevation of the machine with the base plate broken away.
Figure 2 is a sectional plan of the machine.
Figures 3 and 4 are respectively longitudinal and horizontal sections through
the burnishing tool of the machine.
The pillar a is provided with a suitable base plate (not shown) and the bur-
nisher c is carried in a bush c¹ attached to a bracket & rotary in a horizontal
direction.
The burnisher c is thus capable of movement in a horizontal arc around the axis
of the bracket b and it receives a to and fro movement in this direction from an
eccentric d. This eccentric, d is driven by a vertical spindle f running in bear-
ings on the pedestal e and it operates the bracket through the arm g. On the
rotation of the shaft f (which is driven by the pulley h through the cord h¹
running over guide pulleys 2) the burnisher c makes a rapid to and fro move-
ment.
The burnisher c is hollow as clearly shown on Figure 3 and at the bottom tapers
away to a fine opening. The burnisher head or operative part thereof is fitted
with a cock c³ which can be operated by a pinion formed on the cock. This
pinion is driven by a toothed segment formed on one arm of a double lever i
pivotted at 2. The double lever i is rotary upon the bolt and is drawn in an
upward direction by its spring and can be pulled in an opposite direction by
the rod attached to a suitable treadle (not illustrated) and operated at will by the

wax.
The hollow space arranged in the head c serves for the reception of the polishing
The wax is maintained uniformly in a fluid state as the burnisher head c
is kept heated when in use and thus when the cock is opened by the workman
the wax flows out through the port in the cock and the side of the head (shown in
Figure 4) on to the work as required.
To effect the heating of the burnisher head a suitably constructed gas burner k
is provided. This gas burner is carried upon the bracket & so that it takes part

from the burner to the gas supply.
The foot of the machine is arranged according to the class of work operated
upon and to suit the convenience of different workmen.
The operation of the hereinbefore described mechanism is as follows. The
workman sitting in front of the machine holds up the part to be polished against
the head either by hand or a machine rest of a suitable kind the gas burner k
having of course been lit some time previous so as to heat the burnisher. The
burnisher makes a quick to and fro movement over the surface and at the same
time the exact amount of wax necessary for polishing is allowed to flow on to the
work by a pressing down of the foot treadle opening the cock c³. In this manner
and by guiding the edge along, the required polishing and finishing of the boot or
shoe welt or edge is effected.
The advantages obtained by using this machine in comparison with hand labour
are plainly evident as not only is the work produced cheaper but more uniform
and better work is also obtained.
It is to be clearly understood that edges of all kinds can be operated upon and
that the base plate, or method of feeding the work may be varied and all without
departing from the subject of the present invention.
Having now particularly described and ascertained and the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1: An improved machine for welt and edge finishing in boot making and like
purposes consisting in the provision of a hollow burnisher rapidly oscillated to
and fro by suitable gearing and arranged with a cock at its lower end operated
from a treadle by the workman and also arranged with a suitable burner to keep
the burnisher heated and the wax contained within the hollow liquid and as a
means of simultaneously distributing the wax upon the surface of the article as
it is finished or polished.
2: The improved machine for welt and edge finishing in boot making and like
purposes substantially as hereinbefore described and with reference to the accom-
panying drawings.
