Exercising-machine.

Application filed December 5,1903. Serial No, 183,942. (No model.) ’ To all whom it may concci-n:

Be it known that I, Edward W. White, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi5 nois, have invented new and useful Improvements in Exercising-Machines, of which the following is a specification.

My invention relates to exercising - machines; and its primary object is to provide a io new and useful device of this character which is adapted to automatically rewind operatingcords around rotary members or shafts to which they are secured and from which they are adapted to be unwound during the opera15 tion of the machine and offer resistance to their unwinding through virtue of the momentum given to the shafts by the unwinding of the operating-cords, whereby it is possible to rewind the operating-cords or return their hand20 grips to their initial position without the necessity of employing weights, springs, or elastic operating-cords.

A further object of the invention is to provide a device of the character stated which 25 will be cheap, compact,' durable, and efficient and which can be readily secured in any position found convenient and advantageous to exercise any particular muscles.

With the above and other objects in view 3° the invention consists in the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, which disclose the preferred form of my invention, and in 35 which—

Figure 1 is a front elevation of an exercising-machine constructed in accordance with my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a central horizontal sec40 tional view of the machine. Fig. 4 is a transverse sectional view thereof.

Referring to the drawings by reference-numerals, 1 designates the sides, and 2 the front, of a frame or casing in which are mounted the 45 operative members of the machine, said frame being adapted to be secured to a wall, the floor, or to any article at any point found to be convenient or advantageous to exercise any particular muscles. The sides of the frame are 5° provided with centrally-located and alining screw - threaded openings 3 and have their rear edges provided with vertically-disposed flanges 4, which are apertured to permit the machine to be secured in applied position by means of screws or other fastening means. 55 The front edges of the sides are rounded off and provided with vertically-arranged flanges 5, to which the front is removably secured by means of screws 6. A bolt 7, screw-threaded at either end, is removably secured in the open- 60 ings 3, and it is adapted to be secured against accidental displacement and rotation by means of nuts 7^a, which are mounted upon the threaded ends of the bolt and impinge against the sides 1. The impinging of the nuts 7^a against 65 the sides 1 adds rigidity to the frame in a manner that is apparent. The bolt is provided with a compound cone-bearing 9, centrally and rigidly secured thereto, and cone-bearings 10, adjustably mounted upon the threaded 70 ends of the bolt on either side of the cone 9, whereby they may be adjusted toward or from the cone 9. The cones 10 are provided with recesses 11 to permit them to be adjusted by means of a tool. Rotary members or hollow 75 shafts 12 are revolubly mounted upon the cones and have their ends provided with annular ball-races 13, between which and the cones ball-bearings 14 are interposed. It is apparent that the bearings may be adjusted 80 to permit the shafts to revolve with a minimum amount of friction.

The shafts 12 are provided with apertures 15 and 16, arranged at right angles with relation to each other. Operating-cords 17 are 85 secured to the shafts by passing through the apertures 15, thence through the apertures 16 to dispose their free ends on the outside of the shafts, said ends being knotted to prevent the displacement of the operating-cords. 90 The operating-cords pass through apertures 18 in the front plate, and their extremities are provided with grips 19. The shafts are provided with fly-wheels 20, situated at points adjacent the inner ends thereof. 95

The operation of the device may be explained in the following manner: The operating-cords are wound about the shafts. Then the operator grasps the grips 19 and pulls the cords to unwind them from the shafts. The 100

5994 end secured to one of the members and wound one or more times thereon and adapted to be unwound under tension and rewound by virtue of the momentum, imparted to the mem- 40 bers by said cords.

4. An exercising-machine comprising a rotary member provided with a fly-wheel, and an operating-cord having one end secured to the rotary member and wound one or more 45 times thereon and adapted to be unwound under tension and rewound by virtue of the momentum imparted to the member by said cord.

5. An exercising - machine comprising a frame, a bolt secured to the frame, bearings 50 carried by the bolt, a rotary member journaled upon the bearings, and an operatingcord having one end secured to the member and wound one or more times thereon and adapted to be unwound by virtue of the mo- 5 5 mentum imparted to the member by said cord.

6. An exercising - machine comprising a frame, a bolt secured to the frame, bearings adjustably mounted upon the bolt, a rotary member journaled upon the bearings, and an 60 operating-cord having one end secured to the member and wound one or more times thereon and adapted to be unwound under tension and rewound by virtue of the momentum imparted to the member by said cord. 65

In testimony whereof I affix my signature in presence of two witnesses.

770 unwinding of the pulling-cords causes the shaft to revolve. The momentum thus imparted to the shafts rewinds the pulling-cords and returns the grips to their initial position.

The operator again pulls the cords to unwind them. This second and all subsequent unwindings must be begun prior to the cessation of the momentum of the shafts, whereby the unwinding of the cords in opposite direcio tions to the rotation of the shafts offers resistance to the pull on the cords. The momentum of the shaft is permitted to continue after the cords are unwound therefrom by the operator releasing the tension upon the 15 pulling-cords before they are completely unwound.
