PATENT OFFICE PATRICK J'. NEILON, 0F CLEVELAND, OHIO.

SKIPPIVNG MACHINE.

Application filed May 6,

To all whom it may concern:

Be it known that I, PATRICK J. NEILON, a'subject of the King of England, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Skipping Machines, of which the following is a specification, reference being had to the accompanying drawings. 7

The presentinvention has for its purpose the provision of a machine of this character, especially adapted for use at playgrounds, places of amusements or resorts, or may be used in gymnasiums for exercising purposes.

Another purpose is' to provide a machine of this kind, wherein a revoluble tableis mounted upon the base, androtated'by any suitable means, and provided with arms, over which persons may jump or skip as the table rotates, for exercisin the body, causing circulation of the bloo and also exercisingthe muscles of the legs.

A still further purpose is the provision of a skipping machine, wherein the arms over which the person skips, or jumps as the table rotates, are yieldably mounted, so that in case the arms are struck by the persons foot, the arms will give, and then automatically return to their initial "positions, radially from the table.

Still a further purpose is the provision of manually operated means for rotating the table, in combination with a brake mechanism, for preventing the machine from operating too rapidly, in case those who are skipping over the arms are not as agile and as quick as others. In other words the machine may be controlled accordin to the rapidity of the jumping action of those who are exercising with the machine.

It is to be understood that the particulars herein given are'in no way limitative and that while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made I in the apparatus according to circumstances.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings a Figure 1 is a plan view of the improved skipping machine constructed in accordance with the invention; 7

Figure 2 is a side elevation of the same,

showing more clearly the operating means for rotating the table; I

I Figure 3 is a sectional view through the base, turn-table and through the ball or universal joints, which connect the yieldable arms to the rigid arms of the turntable;

Figure 4 is a detail view of the brake, showing how it is constructed, in order to operate upon the sprocket chain for braking the machine; p

igure 5 is a view. of a modified form of the skipping machine showing the same connected to a motor of a sprocket chain, the motor being mounted on the ceiling;

Figure 6 is a view of a further modified form of the skipping machine in side elevation, showing the same connected u with a motor, which may be suspended rom the ceiling of a room; V

Figure 7, is a detail sectional view of. the outer casing of the universal joint 34.

Referring to the drawings, 1 designates a base which is relatively flat, and may be any size and diameter, and square, rectangular or otherwise shaped. This platform or base may be constructed of any suitable material, either wood, metal or'concrete. Preferably the base or platform has a beveled edge, and may be sunk into the ground. It may be made of metal and may be sunk in a concrete flooring.

Rising from the base is a stationary pedestal 2, upon which a revoluble table 3 is rotatably mounted, there being ball bearings 4 between the circular top of the pedestal and the-table, in order to permit the table to rotate freely. Movable with the revoluble table is a bevel gear 5, there being a suitable standard or support 6 passing through the bevel gear and through the table, and connected to the pedestal. This support 6 is provided with lateral bearings 7 which have a bore 8'extending therethrough, for the reception of the shaft 9. On one end of the shaft 9 abevel gear 10 is fast therewith, while a sprocket wheel 11 is fast to the opposite end. The upper end of the support 6 is reduced and-engages through a platform 12, there being a nut 13 for holding the reduced portions of the sup,-

port in position." The platform at its other 7 per end of the leg has a reinforced late 15, which is secured byscrews 16 to te platform. "A seat support 17 has its base secured by screws 18 on the platform, and the upper end of the seat support has a suitable socket 19 for thereception ofthe stem 20 of a suitable seat 21. This stem 20 may be any convenient length, in order to'permit the seat to be adjusted vertically. The stem is rectangular in cross section, to prevent the seat fromvturning, and may be held in different adjusted positions, by means of a set screw 22, whichpassesthrough the wall of the socket and bears against the stem. The seat support inclines upwardly and toward the inner end of the platform so as to support'the operator in a convenient position foractuating thepedals of the driving means.

Depending from the platfrom and secured thereto by screws 23 is a bracket 24, in a bearing at :the lower end of which a crank shaft 25 istmounted. 'This crank shaft also carriesa sprocket 2'6, and the lateral arms of the cranks carry suitable pedals 27, which maybe engaged by the feet of an operator, who may occupy the seat 21, in order to impart vmovement to the crank shaft. The sprocketis engaged with by a sprocket chain 28, which in turn passes about the sprocket- 11. Obviously,when movement is imparted to the crank shaft.25, movementin:turn will be imparted to the shaft carying thesprocket 11 and the bev'elgearl-O, the latter. of which will rotate ,the bevel gear 5 and impart revoluble movement. to the :rotating table.

' A suitable .arcuate rack 29 is mounted upon the platform, and pivotally mounted on the side of the platform is a lever 30 carrying a: suitable hand gripped operated dog'31, for cooperat-ing with the teeth of the rack to hold the lever 80-in-different positions. The lower end ofithe lever 30 carries a conventional form of brake 32, whichLengages-withthe chain 28, for retardingorbraking its action, so that the table mayberotated accord-ingto the speed with which the party who'is using the machine displays when skipping. v

The table is provided with a plurality of radialJarms-33, to the terminalsofwhich by means of universal or ball oints 34 arms 35are connected. The rear ends of the arms 35 have extensions 86, the ends of which are connected by tensioned coil springs 37. These coil springs are arranged radially, and-are in turn connected at 38 tothe table, and act to holdthe arms 35 (the extreme outer ends of which have spherical knobs) radially and substantially in alignment with the arms 33:: Obviously when a person is jumping or skipping over the arms 35, they will yield and resume their normal positions,-'in case they are struck by the feet or legs of the person skipping.

In case the machine is installed in a build in g, such as a gymnasium, the sprocket chain and the sprockets 26 and 11 ma be dispensed with, and in lieu thereo a drive shaft may extend from the center of the bevel gear 5 to the ceiling, and be operatively connected to a suitable motor, which may receive its power from any suitable source. The motor 39 may be of the usual type, and in some'cases the shaft 40 which is connected to the motor may be dispensed with, and instead the sprocket chain 28 may be connected to thesprocket 11 and a-sprocket 41 carriedby the motor.

The various gears, and sprockets. may be suitably housed by means vof boxings 42' The radial rods 35 which are connected to the arms 33 by the universal joints 3 1, are covered with rubber, in order to prevent injury to the: shins or the feet of those skipping over the rods.

The invention having been set forth, what is claimed is In a skipping machine, a revoluble table, a supporting base therefor, armssuniversally: connected to .outer -portions of the table, and yieldableresilientmeans for normally holding the arms radiallypositioned and constructed to-p'ermit the arms [to yield in all directions, in case; the arms are struck by the person skippingover theiarms.

t 2. In. a skipping machine, a revoluble table, a supporting base therefor, radial arms connected to vthe. outer portions pf the tables universally, and vresilient yieldable meansvfor holding said arms normally in horizontal and radial positions.

- 3. Ina skipping-machine,a revoluble table provided with radial arms, asupporting base therefor,additional radial arms'amiversallyconnected tothe outer ends of the first arms, and means yieldably connecting the inner ends of thesecond armswand a portion ofthe table for yieldably supporting the-second arms inhorizontal and radial positions, close to the ground, whereby persons may jump flthereover as the table rotates, and means for rotating the table and including brake :means for retarding the action of the irevoluble tablen v 1. Inna skipping machine, amrevoluble table, a supporting base therefor,: radial arms connected-to the outer portions of the table universally, means for holding said arms yieldably in, horizontal and radial positions, said holding means being yieldable and resilient to return the arms to-their initial positions should they be struck, and meansfor rotating the table and including a device for retarding orbrasking-theiaction of the tables, I

5. In -a skippingimachine, arevoluble member, a support therefor, an arm connected to the revoluble member for lateral swinging movement relative thereto, and resilient yieldable means for normally holding said arm radially positioned relative to the revoluble member.
