A New or Improved Apparatus for Affording and Measuring Certain
Muscular Exercise.
I, HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of 18
Buckingham Street Strand W.C. London, in the County of Middlesex Civil Engineer
do hereby declare the nature of this invention a communication to me from abroad
by Gustav Gaertner Doctor of Medicine of Vienna in the Empire of Austria
Lecturer at the Vienna University to be as follows:-
This invention consists in an apparatus or machine the object of which is to provide
means for healthful muscular exertion the exercise of power being adjustable and
measurable. The machine consists of a suitable frame having journalled therein a
shaft carrying a brake drum or equivalent device over which a stationary belt or
brake band passes. One end of said band is firmly attached or pivoted to the frame
of the machine, the other end is connected to a lever pivoted to the frame of the
machine, said lever carrying a weight displaceable thereon. To the shaft aforesaid
is attached a crank handle to be turned by the person exercising with the machine.
With the shaft is likewise combined a suitable counter whereby the revolutions of
the shaft are recorded. The aforesaid lever is marked with divisions for the setting
of the weight with known friction of the brake device, the said divisions may be
found by temporarily weighting the crank handle and adjusting the aforesaid weight
on the lever until the friction of the brake is found to just support the weighted
crank arm proceeding thus for each of a series of weights on the crank handle, and
marking the lever with the corresponding weights as they are found.
The person exercising adjusts the weight according to the strength required to be
exerted, and turns the crank handle for the desired number of revolutions the latter
being indicated by the dial of the counter.
Dated this 28th day of November 1887.

I HERBERT JOHN HADDAN of the firm of Herbert & Co. of 18 Buckingham
Street Strand W.C. in the County of Middlesex Civil Engineer do hereby declare the
nature of this invention, a communication to me from abroad by Gustav Gaertner
Doctor of Medicine of Vienna in the Empire of Austria, Lecturer in the Vienna
University and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :—
This invention consists in an apparatus or machine, the object of which is to provide
means for healthful muscular exertion, the exercise of power being adjustable and
measurable. Referring to the accompanying drawing in which Fig. 1 is a side
elevation and Fig. 2 a sectional end view, The machine consists of a suitable
frame A having journalled therein a shaft B carrying a brake drum E or equivalent
device over which a stationary belt or brake band H passes. One end of said band H
is firmly attached or pivoted to the frame of the machine at G, the other end is
connected at N to a lever L pivoted to the frame of the machine at F said lever
carrying a weight I displaceable thereon. To the shaft B is attached a crank
handle D to be turned by the person exercising with the machine. With the shaft is
likewise combined a suitable counter whereby the revolutions of the shaft are
recorded. The lever L is marked with divisions for the setting of the weight I with
known friction of the brake device, the said divisions may be found by temporarily
weighting the crank handie and adjusting the aforesaid weight on the lever until
the friction of the brake is found to just support the weighted crank arm proceeding
thus for each of a series of weights on the crank handle and marking the lever with
the corresponding weights as they are found. C is a slide in lever D.

The person exercising adjusts the weights according to the strength required to be
exerted and turns the crank handle for the desired number of revolutions the latter
being indicated by the dial of the counter.
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:
The apparatus and its arrangements for affording muscular exercise of varying
intensity and kind for human beings substantially as illustrated and described.
