FINISHINGOAP, KNOB, OR VASE FOR BEDPOSTS AND THE LIKE.

have invented certain new and useful Imserted therein.

prov'ements in Finishing Caps, Knobs, or Vases for Bedposts and the like, of which the following is the specification.

My invention relates to improvements in finishing caps, knobs or vases for bed posts and the like, and the object of the invention is to devise a simple, cheap, quick and strong means for attaching the knob or the like to a bed post and it consists essentially of a hollow knob having an internal spring bead formed around the shank portion of the knob rendering the orifice of the knob of slightly less diameter than the diameter of the bed post as hereinafter more particularly explained by the following specification.

Figure l, is a perspective view of my knob and bed post. Fig. 2, is a sectional view through the knob showing the bed post in- Fig. 8, is a sectional view of the knob withdrawn from the bed post and showing the bed post in dotted lines.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the bed post.

B is a hollow knob formed of sheet metal.

B is the shank of the knob forming the opening through which the post A extends.

B is an internal bead spun in the metal so as to render the opening through the shank of slightly less diameter than the external diameter of the bed post A. Below the internal bead B the metal is spun into an external bead B the end of the metal being turned up at 13* against the lower side of Specification of Letters Patent.

Application filed April 6, 1912.

Serial No. 688,967.

the internal bead B and formin the opening at the end of the shank of the sam diameter as the post.

l Vhen placing the knob upon the post all that it is necessary to do is to insert the end of the post into the orifice formed by the internal portion 13* and against the internal bead B By exerting pressure upon the knob the internal bead B is expanded to the diameter of the post so that the post slips into the knob past the bead B When the knob is freed the internal bead grips the periphery of the post as shown in Fig. 2 of the drawings.

From this description it will be seen that I have devised a very simple, cheap and strong means for attaching a knob, cap or vase to a bed post, curtain pole or rod end and preventing any other similar knob or the like breaking away from or becoming loose on the end of the post, pole or rod.

What I claim as my invention is:

The combination with a post, of a sheet metal knob or the like therefor having a neck portion terminating in an inwardly curved up-turned portion having an inner annular smooth surface forming a collar designed to slip onto the post, and an inwardly constricted annular portion formed in the neck immediately above the upper end of the up-turned portion and of slightly less diameter than the internal diameter of the upturned portion and adapted to grip the surface of the post, as and for the purpose specified.
