SPECIFICATION forming part Of Letters Patent NO. 670,706. dated March 26, 1901.

7 Application filed fieptember 15, 1900. Serial No. 30,094.. No model.)

To all? whmn it may concern.-

Be it known that l, EMIL R. ERNST, a subject of the Emperor of Germany, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and ImprovedExercising-Machine, of which the following is a full, clear, and exact description.

' This invention relates to improvements in exercising-machines; and the object is to provide a device of this character that shall not only bringinto action and exercise practically all the muscles of a person, but will afiord With these ends in view I have provided a machine that when manually operated has a teetering and rotary or carousal motion.

I will describe an exercising-machine embodying myinvention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective View of an exercising-machine embodying my invention. Fig. 2 is a section substantially on the line a: a: of Fig. 1. Fig. 3 is a plan view, and Fig. 4 is a section on the line y 'y of Fig. 2.

Referring to the drawings, 1 designates a post or mast that may be seated in the ground or otherwise supported, and on the top of this post or mast is a circular platform 2. Mounted to move around on the upper side of the platform 2 are bearing-wheels 3 4, each having ratchet teeth formed on its inner side, the teeth of one wheel being extended in a direction opposite from that of the other wheel. These wheels 3 and 4 are loosely mounted on a shaft 5, and on the outer ends of the shaft 5 are downwardly-extended arms 6, having weights 7 at the ends. A swinging or teetering bar 8 is connected at its central portion to the center of the shaft 5, and at the center of said bar is a slot 9, through which a pivotrod 10 passes, the said pivot-rod being extended upward from the platform. By making the opening 9 in the form of a slot it is obvious that the bar 8 may have a teetering motion, as well as a motion around the pivot-bar.

From a frame 11, attached to the shaft 5, a

rod 12 extends upward, and from this rod 12 a brace-rod 13 extends in opposite directions and connects with the bar 8 near its ends. Pawls 14 and 15 are pivotally connected to the frame 11 and are held in yielding engagement with the ratchet-teethot' the wheels3and 4 by means of springs 16 and 17. It will be seen that the arms of extend at right angles to the bar 8, and of course the pawls l4 and 15 project in opposite directions, as plainly indicated in Fig. 3.

Attached to the ends of the bar8 are swings 18 and 19, consistingof rope or the like, having rings 20 at the lower ends in' which a persons feet may be placed, as indicated in Fig. 1, and to prevent the rings or the lower ends of the two ropes of the swings from spreading too far apart the said lower ends on the rings may be connected by a rope 21 or the like.

In operation two persons may occupy the swings, placing their feet in the rings thereof. Then the person-at one end by throwing the weight of his body outward while the person at the opposite end swings his body inward will cause the end of the bar 8 to swing downward. For instance, the end shown at the right hand in Fig. 1 will cause the pawl 17 to engage with the teeth of the wheel 4, causing said wheel to rotate, and during this motion and as the wheel 3 is also rotated the pawl 16 will pass loosely over the "teeth of said wheel 13. Upon reaching the limit of the downward movement the persons in the swings will reverse the weight of their bodiesthat is, the one at the right will swing the weight of his body inward, while the person at the left will swing the weight of his body outward, and thus the left end will be forced downward, causing the pawl 16 to operate the wheel 3. Therefore it will be seen that the bar 8 will be kept in constant rotation around the pivot as long as the teetering motion is kept up. The weight 7 will aid materially in the operation of swinging the bar.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An exercising-machine, comprisinga bar mounted to rock, and means actuated by the rocking movement of the bar to cause a movement of said bar to travel in a 'circle around its pivotal support, substantially as specified. 2. An exercising-machine, comprising a post or mast, a platform arranged thereon,

ratchet-Wheels supported on the platform and having their ratchet-teeth extended in opposite directions, a teeter-bar mounted on the shaft of said Wheels, a pivot-rod extended from said teeter-bar, pawls engaging with the teeth of the ratchet-Wheels, and supporting devices at the ends of said bar,'substan'tially as specified.

3. An exercising-machine, comprisinga bar mounted to rock, and a step-by-step mechanism actuated by the rocking movement of the bar to cause a movement of said bar to travel in a circle, substantially as specified.

, 4. An exercising-machine, comprising a post or mast, a platform on the upper end thereof, ratchet-Wheels mounted to move on said platform, a shaft on which theratchet- Wheels are loosely mounted, Weighted arms extended from the outer ends of said shaft, a teeter-bar connected to said shaft, a pivotratchet-wheels, said pawls being extended in opposite directions, substantially as specified.

5. An exercisingmachine,comprisingasupport, ratchet-wheels mounted to rotate upon said support, a shaft on which the ratchet Wheels are loosely mounted, a frame on the shaft, spring-pressed pawls pivoted to said frame and engaging with the teeth of the ratchet-wheels, the said pawls being extended in opposite directions, a teeter-bar connected to said shaft, a pivot-rod extended from the mast through an opening in the teeter-bar, a rod extended upward from the frame, and a brace-rod extended from said rod to connections with the teeter-bar near its ends, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing witnesses.

EMIL R. ERNST.
