    N° 13,540 AD. 1895 Date of Application, 15th July, 1895 Complete Specification Left, 15th Apr., 1896—Accepted, 13th June, 1898 PROVISIONAL SPECIFICATION. i Improvements in and appertaining* to Exercising Machines. I Robert John Parkes of 2 Church Street Southport in the County of Lancaster Medical Electrician do hereby declare the nature of this invention to be as follows :— This invention has for its object an improved exercising machine by the use of 5 which the limbs and various portions of the body may be exercised and strengthened and in which the resistance offerred may be easily and conveniently adjusted to suit the strength of the user and the effect desired to be produced. A machine constructed according to my invention consists of a small heavy vertical fly wheel mounted on a spindle and supported on standards affixed to a 10 stand or bed plate. The outside extremities of the spindle carry cranks and foot pedals and the whole is so proportioned that the wheel may be conveniently turned (equally well in either direction) by a person sitting on a chair or seat which may either be separate or form part of the machine. In order to vary the amount of resistance to the users efforts as required 15 I provide an adjustable braking device by means of which pressure may be placed upon the wheel. The periphery of the wheel is provided with a narrow turned groove and the upper portion thereof is occupied by a wire forming a band brake whose one end is fixed to or connected with the bed plate and which after partially embracing the 20 wheel passes under a small pulley near the bed plate on the side next to the user. I provide a light standard adjacent to this pulley, which carries (at a convenient height to be reached by the hand) a screw adjusting device to which the end of the wire passing from the pulley is attached. By turning this adjusting device the tension of the wire may be varied and the friction on the wTheel regulated with the 25 greatest nicety. The action of the machine is peculiarly smooth and agreeable. The machine may also be used by turning by hand. Dated this 13th day of July 1895. CHAS. COVENTRY, 30 Agent for the Applicant.
