EXERC I SER Filed July 25 Patented Feb. 9, 1926.


Exnnorsiin. y 1

Appiieation'ied July 23,1923. Ysemi No. 653,149.

To all Iwhom t may '00u-cern.'

of Glendale, county of Los Angeles, and State of California, have invented certain new and useful Improvements in Exercisers, of which the following is a specification. y

My invention relates to that type of eXercising apparatus adapted for use in developing and strengthening the human muscles, and it has among its salient objects to provide a simple, compact and efficient device of the character referred to which can be easily carried from place to place and quickly attached to any suitable support ready for use to provide a device which can be quickly and easily adjusted for increasing the pull necessary to operate it, thereby making it possible to regulate the device for use by young or old, men or women, weak or strong; to provide a device which eliminates the use of weights or springs and yet capable of providing any degree of resistance to the muscles being used to operate the device;

In order to fully explain my invention, I have shown one embodiment thereof on the accompanying sheet of drawings which I will now describe.

Figure 1 shows an edge view of the device supported upon a hook ready for use:

Figure 2 is a side view thereof with the ends of the cables cut away; and

Figure 3 is a sectional view through thel device shown in the. other views.

Referring now more in detail to the device here shown for illustrative purposes, 1, designates a rotatable element, here shown to be in the form of a duplex pulley having two cable channels, 2, 3, with a hole, 1 1-, through the middle partition member 5, as shown in Fig. 3, to receive a cable, (5. The

cable is inserted through this hole L1, withv its middle portion resting therein and its ends wound around the rotatable yelement 1 in different directions, one end being wound in one of the channels 2, or 3, and the other end wound in the other, as illustrated. The ends of the cables are provided with hand pieces, or gripping means, as 7, shown in the drawings to be spiral in form, similar to a rope, although these can be of any desired form or size. The rotatable element is mounted between two side members, 8 and 9, on a pin or bolt, 1G. At opposite sides of said side members, .ou .se-.id bolt, are two flexible washer like members, 11, 11, which Be it known that I, Briton RY, a crti- VZen of the United States, residing in the city may. be of rubber, fiber or any suitable material, with metal washers, 12, 12, over their outer faces, on said bolt 10, as clearly indicated in Fig. 3. On the opposite sides of the rotatable member 1, next to the side members, 8 and 9, I have placed a disc of cork, or the like, 13, Fig. 3. On the threaded end of the bolt 10, I have shown a small wisher, 14, and a regulatingbar or member, 15, for regulating-the compression of the members on said bolt 10, to increase or diminish the friction on the rotatable element 1.

'At one end of the side members, 8 and 9, is a supporting member 16, adapted to be placed over any suitable hook or support,

as 17, mounted on a wall or other suitable Y support. At Vthe other end of said side members, 8 and 9, is a bolt, 18, with a roller sleeve 19, thereon between the side members n u n 7 to serve as antrfriction means for the cables orflexible members., 6, 6. The bolt 18 is shown to be threaded to the side member 8, and to be provided with a nut 20, to firmly hold said plates 01 side members together and prevent `relative movement between them.

The use ofthe device will be readily under stood from the drawings, but may be briefly described as follows:

It will be understood that it can be supported over head, or on a wall or other support at any desired height. `The hand pieces 7 are taken, one in each hand and alternately pulled andmetracted, turning the rotatable element 1, first in one direction and then in the other, said element taking up and letting out the cable as it is turned. By turning the regulating member 15, any desired friction can be placed on said rotatable4 element desired, thus regulating the amount of force necessary to pull said cables and turn said element. Various uses can be made of said device for developing and strengthening the muscles of the body, and while I have shown and described one practical embodiment of the invention, I do not limit it to the showing made, except as I may be limited by the hereto claims.

' I claim: l

1. In a device of the character referred to, in combination, two side members, a rotatable element mounted therebetween, a cable wound aromid said element with its appended i ends extended and provided with gripping means,`friction elementsv betweensaid side members and said rotatable element and means for tightening and releasing the saine, whereby to regulate-'the' friction on said rotatable element.

2. An exerciser comprising in combination a duplex pulley-like member having tWo cable channels, a cable Wound around said member with its opposite ends extended therefrom and provided with gripping means, side plates forfsupporting said member, yielding friction means for creating friction on said member toreg'ulate the ease with which it can be turned, means ior regulating said friction, and means for supportingsaid eXerciser whereby said gripping means on saidcable ends can be alternately pulled and released, substantially as described.

Signed at Los Angeles, Los Angeles, County, California, this 16th day of July,
