frefera hlg thelhaiiger of spring metal so that the halves of the split shank 11 will be normally spaced apart or separated as shown in Fig. 6 so that a nor mallyclosed strap loop 16 of a punching bag 17 or other article to be supportedcan be slipped through the space and thus mounted on the ring portion of the hanger and be secured thereon so that it cannot escape. In other words, when the closed strap or supporting loop 16 is fitted to the ring of hanger 12 and the halves of shank 11 closed and secured by nut 13 there is no way for the punching bag to escape from the hanger except for the strap to break.

To facilitate the attachment of nut 13 to the split shank 11 the hanger 12 is forced upward through the hole 9 in bushing 8 until the halves of the shank are forced together in close contact as illustrated in Fig. 7 by action of the curved surfaces 12 against the walls forming the perforation. The shank is held in this position until the nut is screwed onto the shank until the hole 13 coincides with the selected hole 11, after which the cotter pin 15 is inserted through such coinciding holes to retain the nut on the shank 11. To facilitate the insertion and withdrawal of the cotter pin in the holes 11 and 13 a slot 18 may be cut in the wall of the bushing 8.

In use, the parts of the hanger are assembled and secured to a support as shown after which the hanger is free to swing or spin when the object it supports such as the punching bag is removed; and the parts are so constructed and arranged that the hanger may spin and swing on the swivel nut 13 and also have additional play or movement bymeans of the swivel bushing in which the swivel nut is supported.

An advantage gained by use of a swivel constructed as above set forth for supporting a punching bag is that the strap loop 16 is supported in the ring 12, which presents a rounded surface for the strap to engage and slide upon and also presents a surface that acts evenly as a resistance to action of the bag without any lost motion. v

Another advantage is that when the hanger is used as a support for a punching bag the speed of the bag is greatly increased over metal. punching bag supports heretofore known. This is made possible by the construction and arrangement of parts in which the strap loop 16 will slide upon the circle 12 without lost motion and the convex surface a of the nut 13 will swivel, on the inner surface 1-1 of the bushing 8 which in turn is swivelly mounted in the cylinder 6.

I claim.

1. A punching bag support comprising a base plate having a threaded opening; a cylinder contracted at one end and threaded into said opening at its other end; a hollow spherical segment seated in said contracted end and having a perforation therein; a supporting member having at one end a ring adapted to receive the strap loop of a punching bag and having at its other end a threaded shank that loosely extends through the perforation in said segment; and a nut threaded onv said shank and adapted to. adjustably retain said support in position, said nut having a convex surface seated on the inner surface of said segment.

2. A hanger having a shank; a swivel nut detachably and adjustably attached to said shank; a hollow bushing in which said shank and nut are movably mounted; a cylinder having a seat in which said bushing is mounted; and a support for said cylinder.

3. A hanger having a split shank adapted to have the strap loop of a punching bag slipped through the space between the halves of the split shank when the hanger is detached; a swivel nut detachably and adjustably attached to said shank; a hollow bushing in which said shank and nut are movably mounted; a cylinder having a seat in which said bushing is movably mounted; and a support for said cylinder.

4. A hanger having a splitthreaded shank adapted to have the strap loop of a punching bag slipped through the space between the halves of the split shank when the hanger is detached; a swivel nut threaded on said shank; means for holding said nut in a fixed predetermined position on said shank; a hollow spherical segment in which said nut is mounted for swivelling movement; acylinder having a seat in which said bushing is swivelly mounted; and a support for said cylinder.

5. A punching bag support comprising a base plate adapted to be secured to a sup? port; a circular extension depending from and detachably connected to said baseplate and being contracted at'its lower end; a hollow spherical segment supported by said contracted end and having a perforation therein; a'hanger having a shank loosely extend ing through said perforation and adapted to swivel therein; and means adjustably mounted on said shank to support said hanger.

6. The combination with an article to be supported having a supporting loop; of a base plate having a threaded opening; a cylinder contracted at one end and threaded into said opening at its other end; a hollow spherical segment seated in said contracted end and having a perforation therein; a hanger having a split shank normally spaced'apart to receive said loop, said shank extending through said perforation; and means seated on the inner surface of the hollow segment to retain said hanger in mounted position. V

7. A punching bag support comprising a bag supporting member having at one end a threaded shank and at its other end a ring adapted to receive the strap loop of a punching bag; a hollow bushing in which said shank is movably and loosely mounted; a nut threaded on. said shank and having a surface slidaoly seated on the inner surface of said bushing; a cylinder in which said bushing is mounted; and a support for said cylinder.

8. A punching bag support comprising a bag supporting member having at one end a ring adapted to receive the strap loop of a punching bag and having at its other end a threaded split shank adapted to have the strap loop of a punching bag slipped 18 through the space between the lialves of the split shank when the hanger is detached; a hollow bushing having a perforation through which said split shank extends; a nut threaded onto said shank and adapted to adjustably secure said ring relative to said bushing; and a support for said bushing.

. In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 3rd day of May, 1923.

VILLIAM REES HARLEY.
