Comments: N/A

Description: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. For shaft-carried products, a universal type interchangeable hub including a sleeve having a shaft accommodating bore with a longitudinally extending keyway and exterior longitudinally extending tooth-like splines interspersed with circumferentially spaced block teeth, said keyway being in radial registry with one of said block teeth.

2. A universal type interchangeable hub according to claim 1, wherein said sleeve has a radially disposed threaded bore through one of said block teeth with a set screw therein for affixing said sleeve on a shaft.

3. A universal type interchangeable hub for shaft-carried products according to claim 1, wherein the hub consists of two parts, namely a sleeve having a shaft-accommodating bore with a longitudinally extending keyway and exterior longitudinally extending tooth-like splines interspersed with circumferentially spaced block teeth, said keyway being in radial registry with one of said block teeth, and a collar with an axial sleeve-accommodating opening correspondingly formed to register with said splines and circumferentially spaced block teeth mounted on said sleeve in non-rotatable press-on relation with its outer face flush with one end of said sleeve.

4. The combination with the hub structure according to claim 1, of a shaft-carried product having an axial sleeve-accommodating opening correspondingly formed to register with the
splines and block teeth of said sleeve for longitudinal press-on engagement therewith.

5. The combination with a hub according to claim 1, wherein the sleeve is exteriorly threaded to a depth not exceeding approximately 50% of the spline depth, of a shaft carried product having an axial sleeve-accommodating opening correspondingly formed to register with the splines and block teeth of said sleeve for longitudinal press-on engagement therewith and a pair of interiorly threaded collars screwed on opposite ends of said sleeve into tight and locking engagement with opposite faces of said product.

6. The combination with the universal type interchangeable two-part hub according to claim 3, of a shaft-carried product having an axial sleeve-accommodating opening correspondingly formed to register with the splines and circumferentially spaced block teeth of said sleeve non-rotatably mounted in press-on relation on said sleeve and in tightly engaging juxtaposed relation to said collar and means attaching said product to said collar.

7. The combination with the universal type interchangeable two-part hub according to claim 3, of a shaft-carried product having an axial sleeve-accommodating opening correspondingly formed to register with the splines and circumferentially spaced block teeth of said sleeve non-rotatably mounted in press-on relation on said sleeve and in tightly engaging juxtaposed relation to said collar and circumferentially spaced fastening screws extending longitudinally through said product and threading into said collar.
