IMPROVEMENTS IN CRUTCHES AND WALKING STAFFS
Year: 1886

page_text: I, WILLIAM DANIELS of No. 11 Norwood Street, Ashford, in the County of
Kent, Manufacturer of Ambulance Materials, do hereby declare the nature of my
invention for IMPROVEMENTS IN CRUTCHES AND WALKING STAFFS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention of improvements in crutches and walking staffs consists in the
provision of means for altering and adjusting the length of crutches or staffs
together with or without the addition of a spring or springs for relieving the users
from shocks or jar whether the support is taken under the arms or by the grasp of
the hands.
Referring to the accompanying sheet of illustrative drawings. Fig. 1 shews the
elevation of a crutch with my improvements of adjustment and spring combined
and contained within the tube marked A, a full size section of the lower end of
this crutch shewing the manner of construction and details of the arrangement is
shewn by Fig. 2, and the following is a description of the parts as shewn in that
figure, viz: A is a tube of metal, at the bottom end of which is soldered an inside
collar marked B which acts as a stop for the plunger C; D is part of the staff or
standard of the crutch and to which the adjusting screw marked E, is made fast;
F is the nut of the adjusting screw, this nut is made circular to fit the tube A and
is fixed thereto by solder and pins, after the plunger and spring are placed in
position; G is the spring. H is an india rubber foot fixed to the plunger. As
regards the manner of construction with this arrangement, the nut F is first run
upon the screw E from the upper end of the screw, this end of the screw is then
fixed into and secured to the standard D; the plunger C and spring G having been
placed within the tube A, the end of the staff or standard D with the adjusting
screw and nut is inserted, and the nut secured to the tube by solder and pins,
a small amount of initial compression being put upon the spring; The india
rubber foot H is then fixed to the end of the plunger. By revolving either part of
the staff the adjustment can be made within the limit allowed by the length of the
screw, and the space x to x.
Fig. 3 is a full size section of part of a crutch shewing the means of screw
adjustment only, which may be used in both the upper and lower parts of a
standard in order to regulate the length between any parts; A is a tube of metal

page_text: in which one part of the standard B is securely fixed by pins marked CC; D is
the other part of the standard having the adjusting screw E with nut F fixed
thereto; this part being inserted within the tube A, the nut F is made fast to the
tube by solder and pins.
By revolving either part of the standard the adjustment can be made within the
limit allowed by the length of the screw, and the space x to x.
Fig. 4 is a full size section of the bottom end of a crutch or walking staff
shewing the arrangement for spring only. A is a tube of metal, having an inside
collar B, soldered to the lower end to act as a stop for the plunger C; D is the
spring. The plunger C, and spring D being first placed in position within the
tube, the end of the staff E is then inserted and securely fixed to the tube by
pins or screws; F is an india rubber foot fixed to the end of the plunger.
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 is:
1. The construction of crutches and walking staffs with screws for altering and
adjusting the length.
2. The construction of crutches and walking staffs with a spring either of metal
or india rubber, placed at the lower part.
