Wheel.

Application filed August 18, 1909. Serial No. 513,497.

To all whom it may concern:

Be it known that I, Edward C. Jones, a citizen of the United States, residing at Plymouth, in the county of Luzerne and 5 State of Pennsylvania, have invented new and useful Improvements in Wheels, of which the following is a specification.

This invention relates to improvements in pulleys, sheave wheels and the like, and the 10 object of the invention is to provide a wheel of this character with detachable rim sections, positioned between the flanges of the wheel, which are adapted to provide a wearing surface therefor and which .may be 15 readily replaced when worn, thus obviating the necessity of throwing away the body of the sheave when the rim portion becomes worn, and also rendering the use of such sheaves materially less expensive.

With the above, and other objects in view which will be more apparent as the description progresses, the invention resides in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings there has been illustrated a simple and preferred embodiment of the invention and in which,

Figure 1 is a transverse sectional view of a wheel or shoe provided with the improve30 ment. Fig. 2 is a perspective view of the wedge-shaped retaining element. Fig. 3 is a central horizontal sectional view of the wheel. Fig. 4 is a detail side elevation, illustrating the manner in which the co-act35 ing ends of the rim sections are connected together. Fig. 5 is a top plan view of the members illustrated in Fig. 4.

In the accompanying drawings the numeral 1 designates an ordinary sheave 40 wheel or pulley. This wheel 1 has its periphery beveled in the usual manner and is provided with a central peripheral groove 2. The groove 2 is provided at spaced intervals with suitable openings 3 communi45 eating with the inner face 4 of the wheel.

By reference to Fig. 1 of the drawing, it will be noted that the face 4 is of less width than the rim of the pulley, so as to provide a suitable offset between this projecting 50 face, for a purpose hereinafter to be set forth. The annular groove 2 of the pulley 1 is adapted for the reception of a plurality of segmental rim members 5. These rim members 5 are constructed of a harder material 55 than that of the main body of the wheel and the said rim sections have one of their edges provided with spaced lugs 6 while their opposite ends have their faces provided with spaced pockets 7 which are adapted for the reception of the lugs or 60 projections 6 of the co-acting rim sections. The rim sections 5 are each provided with depending ear members 8 positioned upon the under faces of the said members adjacent the offsets or projections 6. The 65 ears 8 are adapted to project through the openings 3 of the wheel and are provided with elongated slots 9. The slots 9 are adapted for the reception of suitable wedgeshaped retaining members 10, one of which 70 being illustrated in detail in Fig. 2 of the drawings. It will be noted by reference to this Fig. 2 that the said retaining element 10 has each of its end portions threaded as at 11, and these threaded portions are 75 adapted for the reception of suitable nuts 12 which bear against the face of the wheel, . so as to effectively retain the member 10 in position within the openings of the ears and at the same time secure the nuts tightly 80 against the offset faces of the wheel to prevent the lateral movement of the wedge members 10.

From the above description, taken in connection with the accompanying drawings, 85 it will be apparent to those skilled in the art to which the invention appertains, that it is merely necessary, when the bearing rims 5 become worn, to easily and quickly remove the same and to replace the worn ⁹⁰member with a new one. It will be also observed that the rim members 5 are provided with the ears 8 adjacent the lugs or projections 7, thus providing means for effectively retaining the said sections to- ⁹⁵gether, it being understood, of course, that the said lugs 6 engaging within the pockets 7, effectively retain this end of the rim tightly upon the inner wall of the recess 2.
