IMPROVEMENTS IN SPURS AND IN BOOT HEELS THEREFOR
Year: 1884

page_text: I PETER JENSEN of 33 Chancery Lane in the County of Middlesex do hereby
declare the nature of said invention for "IMPROVEMENTS IN SPURS AND IN BOOT
HEELS THEREFOR (A communication to me from abroad by W. Schulze of
Brederlow in the Empire of Germany Landowner) to be as follows :-
"
:-
This invention relates to a spur which may be pushed in or drawn out of the
boot heel.
The spur itself is formed as a stem or shank provided with the usual small wheel
in one end and arranged to push into or pull out of a cast box which is recessed
or bored out to receive it and which is built into the boot heel. The cross section
of the spur is by preference circular, but it may also be square or of any other
form. A stud or feather which projects from the shank of the spur and runs in a
corresponding groove in the box hinders the spur shank from turning round. The
spur is pushed out of its box by a tolerably strong helical spring and the shank of
the spur is hollowed out at the inner end for the reception of the helical spring so
that the spring may be as long as possible or necessary. The fixing of the spur
in the drawn out and pushed in positions, is effected by a cross pin which projects
through one side of the heel of the boot. This pin is pressed outwards by means
of a spring and has a nose which takes into one of two holes formed in the
shank of the spur. When the spur is pushed out, the nose of the pin takes into
an inner or further hole in the spur shank, and when pushed in, the nose takes into
an outer or nearer hole.
In order to bring the spur out the only thing necessary to do is to press on the
pin whereupon the spur is pushed out of the box by the spring. When the spur
has come to the end of its outward travel the pin catches into the further hole on
the spur sbank which is thereby fixed in position. If the spur is to be again
pressed in the pin is pushed in, and the spur is pressed into the box until the pin
again catches in the nearer hole.
The outer opening of the box may if desired be closed by a slide in order to keep
the dirt out. To ensure against the box coming loose in the heel it is formed
with a projection on one side wherein is provided a chamber for the helical spring
for holding the cross pin in position.

I PETER JENSEN of 33 Chancery Lane in the County of Middlesex do hereby
declare the nature of said Invention for "IMPROVEMENTS IN SPURS AND IN BOOT
HEELS THEREFOR (A communication to me from abroad by W. Schulze of
Brederlow in the Empire of Germany, Landowner) and in what manner the same
is to be performed to be particularly described and ascertained in and by the 5
following statement :-
This invention relates to a spur which may be pushed in or drawn out of the boot
heel. The construction of the spur is shown in the accompanying drawings of
which Figure 1 is a part longitudinal vertical section; Figure 2 a part plan section,
and Figure 3 detail sectional view.
The spur itself 6 is formed as a stem or shank provided with the usual small
wheel in one end and arranged to push into or pull out of a cast box a which is
recessed or bored out to receive it and which is built into the boot heel. The cross
section of the spur b is by preference circular, but it may also be squaro or of any
other form. A stud d or feather which projects from the shank of the spur and runs
in a corresponding groove in the box a hinders the spur shank from turning round.
The spur is pushed out of its box by a tolerably strong helical spring f, and the
shank of the spur is hollowed out at the inner end for the reception of the helical
spring so that the spring may be as long as possible or necessary. The fixing of
the spur in the drawn out and pushed in positions is effected by a cross pin g
which projects through one side of the heel of the boot. This pin g is pressed
outwards by means of a spring hand has a nose 7' which takes into one of two
holes b formed in the shank of the spur. Figure 1 shows the spur pushed out,
when the nose g₁ of the pin g takes into an inner or further hole 6' in the spur
shank, Figure 2 shows it when pushed in, the nose g' then taking into an outer or
nearer hole b.
In order to bring the spur out the only thing necessary to do is to press on the
ping whereupon the spur is pushed out of the box a by the spring f. When the
spur has come to the end of its outward travel the pin catches into the further
hole b' on the spur shank which is thereby fixed in position. If the spur is to bo
again pressed in, the pin g is pushed in, and the spur is pressed into the box a until
the pin g again catches in the nearer hole b.
The outer opening of the box a may if desired be closed by a slide in order to
keep the dirt out. To ensure against the box a coming loose in the heel it is formed
with a projection on one side wheroin is provided a chamber for the helical spring h
for holding the cross pin g in position.
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 as the invention communicated to me is:-
A spur that can be slid in and out consisting of the sliding spur proper b having
a guide itud d, the spring fand the spring stop pin g g', said parts being arranged
ilin case a which is inserted in the boot heel.
