IMPERIAL

PATENT OFFICE.

The purpose of the device described below is to help those people who it is not possible to improve your leg muscles by taking regular walks or climbing mountains to strengthen, to artificially procure the beneficial effect of the movements mentioned.

When using the device, the levers cc ^{1 are} alternately stepped on and so the foot and leg muscles require approximately the same force that has to be used to move the body forward when walking or mountain climbing.

The apparatus consists of the stands α a ^l and bb \ the foot levers cc ¹ attached to both sides,
when pedaling
the levers cc

the poor dd ¹ to stop

and the levers e e ¹ , which open

¹ rest and strain them.

The step levers c c ¹ are provided at the rear with Ύήιχζη ff 'for setting up the foot and loaded at their other end by weights gg ^1; they swing around a rod h which is inserted in slots a ¹ on the uprights aa ¹ at the appropriate height. Depending on the size of the person doing the gymnastics, the levers c c ^{1 are} pulled out more or less, for which purpose the step levers are provided with cutouts c 1 for hooking into the bar. Depending on the force respectively. the strength of the gymnast, the weights gg ^[ closer to the point of oscillation of the levers cc ', namely the bar / 7, moved or removed from the same.

A further load on the treadle levers cc ¹ occurs through the levers ee ¹ , which can swing freely around a rod i and lie with rollers kk ^l on the rear part of the levers cc ^1.

The levers ee ^l are loaded by weights / W ^1; When stepping on the footsteps ff ¹ , the rollers roll on the rear ends of the levers cc ¹ . dd ^x are two arms which are provided with holes η n ^l at different heights and are connected by a rod m . The rod m can thus be adjusted at different heights. The arms dd ^l are firmly against the stand from respectively. a ¹ b ^x screwed and then serve as reference points for the arms during gymnastics.

To the stand α b respectively. To be able to adjust α ¹ b ¹ at any angle to each other, the connecting rods 0 o ^{1 are} provided with slotted holes o ^{2 between them.}

When using the device, after the levers c are hooked onto the rod h at the appropriate height and with appropriate lever arms, one steps on the steps ff ¹ and turns by alternately stepping on these steps and thereby alternately lifting the weights gg ^l and // , / ¹ no. ¹ a work that corresponds to the manner required for walking and mountain climbing.

The levers ee ¹ with the weights //, / ¹ Z ¹ can also be set to their function or switched off completely, so that when the

Lever c only the weights gg ^{l have} to be overcome.
