Improvements in the Heels of Boots and Shoes.
Wo, WILLIAM HITCH PURSEк, of No. 46 Bent Street, Moonee Ponds, near
Melbourne in the Colony of Victoria, Builder, and WALTER MORRISON, of
Pascoe Vale Road, Moonee Ponds, near Melbourne aforesaid, Bootmaker, do
hereby declare the nature of this invention to be as follows:-
This invention relates to those classes of heels for boots and shoes which are so
constructed as to admit of their wearing surfaces or treads being removed when
worn, and either fitted upon the opposite boot or else replaced with a new one.
"
A prior invention of ours consists of a pair of metal or other slides, one fitted
with outwardly projecting flanges and the other with guides adapted to receive said
flanges. A metal spring catch was used to look the two slides together when the
heel was in position, and a small hole was made through the "top piece or
removable part of the heel to allow of said spring catch being forced out of engage-
ment with the opposite slide by means of a bradawl. It has been found in practice
however, that this arrangement is open to several objections, and we have therefore
devised the present invention in order to remedy thesu defects.
This present invention consists essentially in the use of a pivotted or other pawl
or catch so constructed and arranged that it will prevent the two parts of the heel
froin becoming disengaged from each other whilst the boot is in its normal position,
but which will not offer any impediment to the unfastening and removal of the heel
when the boot is placed upside down. This pawl or catch is applicable to other
kinds of removable heels besides those referred to above. For example, it can be
applied to prevent the removal of heels attached by screws, slides, sockets, clips or
other equivalent contrivances.

Improvements in the Heels of Boots and Shoes.
We, WILLIAM HITCHI PURSER, of No. 46 Bent Street Moonee Ponds near
Melbourne in the Colony of Victoria Builder and WALTER MORRISON, of
Pascoe Vale Road Moonee Ponds near Melbourne aforesaid Bootmaker 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 those classes of heels for boots and shoes which are so
constructed as to admit of their wearing surfaces or treads being removed when
worn, and either fitted upon the opposite boot or else replaced with new oues.
According to our.invention, we secure a pair of slides, one to the fixed and one to
the removable part of the heel, and we form said slides one with outwardly pro-
jecting flanges, and the other with grooves or guides to receive said flanges. One
of these slides we provide with a pivoted or other pawl piu or catch, so arranged
that when the boot is turned over into its ordinary position it will engage with the
opposite slide, and will thus look the two slides and therefore the two parts of the
heel together, whilst the boot is in its normal position, but which will not offer any
impediment to the removal of said heel when said boot is placed upside down.

page_text: In order to still further ensure the heel or removable part of said" heel being
secured firmly upon the boot, we use a vertically sliding pin or bolt, working in
bearings in one of said slides, and arranged to drop into engagement with a hole or
recess in the other side when the boot is in its ordinary or wearing position.
We propose to form two holes or recesses in the lower slide to receive this
vertically sliding bolt or pin, in order to prevent the removable part of the heel
from coming off accidentally in the event of its not having been pushed sufficiently
home to allow said pin and pivoted pawl to drop into their engaging positions.
.of
Both slides are set so that the flanges of the one and the guides or grooves o
the other are inclined upwards from the front towards the back of the heel, in order
to draw the removable part tightly against the fixed part of the heel when said
removable part is put on. This inclination may be given to said flanges and guides
either by making the slides themselves inclined—that is, of greater thickness at one
end than the other-or by cutting out the leather of the heel and securing parallel
slides upon the inclined face of the part of the heel thus cut out.
Referring to the accompanying drawings:
Figure 1 is a side elevation of a boot with the heel constructed according to our
invention.
Figure 2 is a plan of the underside of the fixed part of said heel.
Figure 3 is a plan of the slide fitted upon said fixed part of the heel.
Figure 4 is a transverse section on line 4-4, Figure 3.
Figura 5 is a plan of the removable part of the heel, together with said slide.
Figure 6 is a plan of said slide; und
Figure 7 is a vertical transverse section on line 7-7, Figure 6.
Figuro 8 is a vertical transverse section on line 8-8, Figure 1.
Figures 9 and 10 are respectively a plan and side elevation of the pawl; whilst
Figure 11 is a sido elevation of the pin or bolt abova referred to.
Figure 12 is a vertical central section of the heel of a boot or shoe constructed
according to our invention, and showing same partly removed; whilst
Figure 13 is a similar view of said heel when in its working or fastened position.
The same letters of reference indicate the same parts in all the figures.
A-B represent a pair of slides which are attached one to the fixed part C and
the other to the removable part D of the heel of a boot or shoe, whilst a represents
the guides or grooves which are formed or provided upon the slide A to receive the
outwardly projecting flanges 6 on the other slide B. These slides may be fixed to
the heel by screws or otherwise, as found inost convenient.
E represents the pawl or catch which is pivoted, as illustrated at e, to the upper
alide A and is arranged to hear against a stop piece on the opposite slide B, when
the removable part of the heel is in its normal position, as illustrated in Figure 13.
lu order to effectually fasten the removable part of the heel in position, we use a
sliding pin or bolt F as well as the pivoted pawl E, and we arrange said sliding
pin or bolt so that it works freely in bearings or through an opening in the upper
slide A and drops into engagement with the hole or recess in the bottom slide
as shown, when the boot is turned over into its ordinary position. As this vertically
sliding pin or bolt is not liable to be jorked up out of engagement with the bottom
slide by the same movement that would affect the pivoted pawl, the likelihood of
the heel coming off accidentally whilst in use is reduced to a minimum.
This pin or bolt may be round, square, or other shape in oross section, and may
be arranged either vertically or horizontally.
We prefer to provide a second hole f", in addition to f', to receive the pin or
bolt F in the event of the removable part of the heel not having been securely
fastened in the first instance, and gradually working off. This second hole will
provent said removable part from coming off entirely and being lost, thus giving
the wearer an opportunity of fitting it into its correct position-that is, so that the
pin or bolt will engage with the hole and the pivoted pawl engage with its
stop piece ou the lower slide. If preferred, more than one additional hole ƒª can
be provided.
