The invention comprises amongst its essential features a walking stick made in sections, a battery or other source of electric current located within one of the said sections and adapted to' send an electric current through the handle of the stick, and means for making and breaking the circuit as the stick makes contact with and is lifted off the ground respectively. The current is conducted from the battery to the metal handle of the walking stick or through metal plates attached thereto, whence it passes into the hands of the user. The arrangement of the parts is such that when pressure is brought to bear upon the stick as the end is placed in the ground m walking, the stick as a whole is compressed, relative telescopic movement taking place between its sec¬ tions. This relative movement is employed to operate a make and break switch so that a current circulates in the handle of the stick only during such time as pressure is brought to bear on it and maintained as aforesaid. Immediately the said pressure is removed, springs arranged between the sections, return them to their normal positions and in doing SO' at the same time break the circuit. The stick may also be provided with a spring ferrule which has an anti- vibratory effect and absorbs the sudden jar consequent on the stick first meet¬ ing the ground. In order that the invention may be properly understood reference is made in further describing the same to the accompanying drawings, wherein Figure 1., shows an outside view of a medical electric and magnetic appliance constructed according to this invention. Figure 2., is a central vertical section of the same on an enlarged scale, and Figure 3., a detail view of a modification. Like parts are designated by the same reference characters in all the figures. Referring to the drawings, 2 is the walking stick which is made in telescopic sections, and 3 is a battery located therein and adapted to cause an electric cur¬ rent to circulate in the metal handle 4 of the stick, as and when required, by means of a make and break switch 5 operated by the relative telescopic move¬ ments of the said sections when the stick is in use. Externally the stick 2 may be of any conventional type and in the example shown is made in two main sections 2a, 2b, of which the lower section 2b may be made in two or more parts united by screw connections 11. The upper section 2a carries the handle 4 and is preferably formed hollow throughout and of metal or other conducting material. [Price .J
