PROVISIONAL SPECIFICATION.
Improvements in the Feet of Artificial Legs, Crutches, and
the like..
ALBERT THOMAS JUDD Saddler and Harness Maker of 24 High Street
Kingston-on-Thames do hereby declare the nature of this invention to be as
follows:-
The small bones of the human foot are so articulated together as to distribute
and reduce the concussion that would be otherwise felt in bringing the foot to the
ground in ordinary progression.
With the exception of the padding immediately connected with the stump
wooden legs present no such provision as that above mentioned, and the shock to
the system at every step is very considerable, moreover even in the case of cork legs
furnished with ordinary boots there is always some danger of slipping on the heel
either in wet or frosty weather.
My invention consists in the application of a specially contrived firm but elastic
rubber buffer fitted iuto a brass socket alone and held in situ by an annular screw
cap. The buffer may thus be very readily applied or removed as may be required.
Dated this 9th day of February 1894.

I ALBERT THOMAS JUDD, Saddler and Harness Maker, of 24 High Street
Kingston-on-Thames, 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 small bones of the human foot are so articulated as to distribute and reduce
the concussion that would be otherwise felt in bringing the foot to the ground in
ordinary progression. With the exception of the padding immediately connected
with the stump wooden legs present no such provision as that above mentioned and
the shock to the system at every step is very considerable moreover even in the
case of cork legs furnished with ordinary boots there is always some danger of
slipping on the heel either in wet or frosty weather.
My.invention consists in the application of a specially contrived firm but elastic
rubber buffer fitted into a brass socket alone and held in situ by an annular screw
cap. The buffer may thus be very readily applied or removed as may be
required.

In the accompanying sheet of illustrative drawings
-
Fig. 1 is an elevation of a foot of an artificial crutch constructed according to
this invention, Fig. 2 is a vertical section of the same, and Figs. 3, 4, and 5 are
detail views.
The rubber or other elastic buffer e is secured in the socket by the cap d
screwing on the socket and bearing on the flange of the rubber buffer and thereby

page_text: holding it firmly in position. The socket c is secured to the foot b of the pin a by
the centre pin f and screws g.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Securing an elastic buffer to an artificial leg or the like by means of a socket"
secured to the said leg and a cap screwing on to the socket and adapted to retain
the buffer substantially as described and shown in the accompanying drawings.
Dated this 9th day of November 1894.
