E. A. TUTTLB. Exeroising Machine.
No. 231,869. Patented Aug. 31,1880.
WITNESSES IJVVEJV'TOR N. PETERS, PHOTU-LITMOGRAFHE SH N D C UNITE STATES PATENT Orricnt EDWARD A. TUTTLE, OF NEW YORK, N. Y.
EXERCISING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 231,869, dated August 31, 1880. Application filed September 25, 1879.
To all whom it may concern:
Be it known that I, EDWARD A. TUTTLE,
a resident of the city of New York, in the county and State of New York, have invented a new and useful Improvement in Exercising- Machines, (Case 13,) of which the following is a specification.
This invention consists of a guideway and roller so combined and arranged relatively to the platform that its level is maintained when rising and falling without the parallel bar or lever contrivance commonly used for that purpose, and with only one pivot connection of the levers to it.
The construction is simpler, the action hetter and the wear less than in the aforesaid parallel-bar con trivan ee.
Figure l is partly a side elevation and partly a section of myimprovement. Fig.2 1's aplau of the under side of the machine.
A represents the platform, on which the operator stands to raise and lower himself by the levers B, which I he works by the handles 0. These levers have their fulcrums on the standards D of the baseE, and are pivoted to the platform at F for lockin g it, said pivots being located between the place where the operator stands-say at G-and the opposite end of the platform.
Near the center of the base E, I have located a curved guideway, H, which is so situated thatthe roller I, mounted 011 the under side of the platform A by a bracket, J, will run on the same, thereby maintaining the level of the platform while rising and falling. The radius of the curve of this guideway is the same as the distance between pivots F and fulcrums D, less half the diameter of the roller. The arrangementis such that the platform is a little heavier on the side of pivots F upon which the operator stands than on the other side, so that the roller keeps its level by hearing against the guide. The bracket might bear upon the guide without the roller, but it would make needless friction. There may be two such guides and rollers, if preferred, one near each side of the platform; but it is believed that one in the middle is just as good.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
The combination of one or more guideways, H, and a roller, I, with the movable platform and levers of an exercising-machine, to maintain the level condition of the platform, substantially as described.
EDWARD A. TUTTLE.
