9 Claims. (Cl. 1847.5)
This invention relates generally to a roller and shaft assembly and more particularly to a roller and shaft which are fabricated together in one operation.
In the mass production factories of today, material handling and assembly operations represent a substantial. portion of the manufacturing costs of an article. For this reason every effort is being made to decrease the number of assembly operations required and the amount of material handled. It is well known in the art to support a movable object by a roller and shaft assembly, and such assemblies are being installed in many mass production articles. Heretofore, separate operations have been required to first insert the roller on the shaft, and then to secure stop means on the end of the shaft to prevent the roller from working its way off that shaft. The roller, shaft and stop means are normally stored in separate containers on the assembly line in order that they are readily accessible to an assembler. The present invention provides a roller and shaft assembly which requires less material handling and fewer assembly operations than the conventional roller and shaft assembly.
- One object of the present invention is to provide an assembly in which a roller and shaft are fabricated together as one article.
. Another object of the invention is to provide a roller and shaft which can be assembled in one operation.
2,724,867 Patented Nov. 29, 1955 "ice the invention, Figs. 1 and 2 show an article of manufacture which comprises a shaft 10 and a roller 11. The shaft 10 is generally cylindrical shaped with end 12 having its outer edge 13 beveled slightly. Spaced inwardly from end 12 is an annular shoulder 14 which divides the outer surface of the shaft 10 into a bearing portion 15 and a mounting portion 16. These two portions are shown of equal diameter but could be constructed of unequal diameters if desired. End 17 of the shaft is inclined inwardly toward the center thereof. The outer edge of end 17 is provided with a small'a'nnular flange 18 which protrudes above bearing portion 15.
Roller 11 is constructed in the shape of a flat disc having both sides of its outer edge 19 curved smoothly inwardly. The central portion of the roller 11 is provided Another object of the invention is to provide a roller and shaft assembly which does not require separate stop means for maintaining the roller on the shaft.
Another object of the invention is to provide an assembly in which the shaft is provided with an annular flange having substantially the same diameter as the internal bore of the roller so that the roller'can be forced theresection of material which may be easily broken by forcing the roller onto the shaft.
Another object of the invention is to provide a roller and shaft assembly which is economical to manufacture. These and other objects of the invention will be pointed out in more detail hereinafter, or will be apparent to those skilled in the art upon reading the specification, reference being had to the accompanying drawings, wherein a prefered form of the present invention is clearly shown.
in the drawings:
Fig. l is an end view of a roller and shaft fabricated as one article.
Fig. 2 is a longitudinal view, partly in section, of the roller and shaft of Fig. 1.
Fig. 3 is a longitudinal view, partly in section, of the roller and shaft showing the roller being forced onto the shaft.
Fig. 4 is a longitudinal view, partly in section, of the roller and shaft showing the roller in operating position.
Referring to the drawings for a detailed description of with a strengthening hub 20.which projects toward the shaft 10. A centrally disposed bore 21 extends through the roller 11 and has substantially the same diameter as the outer surface of annular flange 18 of the shaft 10. As best seen' in Fig. 2, the shaft 10 and roller 11 are fabricated as one article and are joined by a small section or web 22 of material. The joining web 22 of the material is only a few thousandths of an inch in thickness but has been exaggerated in the drawing for purposes of clarity. The joining web 22 is disposed between the outer edge of theflange 18 and the inner edge of hub 20, and may be a continuous section extending completely around the periphery of the flange 18, or may be a plurality of short sections spaced around the periphery of the flange.
It has been'found that a suitable material for the shaft 10 and roller 11 is a high impact plastic, such polystyrene, polyethyhene, ethyl cellulose, cellulose nitrate, nylon or etc. Plastic is adaptable for molding so that the shaft 10 and roller 11 can be integrally molded in one operation. After molding, the roller 11 and shaft 10 is ready for assembling. In Fig. 3 and Fig. 4 of the drawing, a portion of a frame 23 is shown in section. This frame isprovided with an aperture therethrough into which the beveled end 12 of the shaft 10 is secured with shoulder 14 disposed against the frame. A force is then applied inwardly against the outer surface of the roller 11 as indicated by the arrows in Fig. 3. This force breaks the joining web 22 between the roller 11 and shaft 10 and forces the roller 11 over the flange 18. In Fig. 3 the roller 11 has been forced part way over the flange 18, whereasin Fig. 4 the roller has been forced completely over the flange 18 onto the bearing portion 15 of the shaft 10.
Joining web 22. is of such small size that it breaks easily and smoothly so that the roller 11 will slide over flange 18. A suitable tool or machine may be used for forcing the roller 11 over the flange 18 in order to maintain the axial bore 21 in alignment with the shaft 10 during the assembling operation. After roller 11 has been forced onto the bearing surface 15 of the shaft, it will be free to rotate thereon since the bore 21 is of larger diameter than bearing portion 15. Shoulder 14 will position the shaft 10 in reference to the frame 23 and will prevent the roller 11 from rubbing against the frame. It is contemplated that a drawer or other movable object be supported upon the outer edge 19 of the roller 11, and since flange 18 is substantially the same size as bore 21, the flange will prevent the roller 11 from working its way off the shaft 10.
From the foregoing description, it can be readily understood that the roller and shaft assembly described has many advantages for mass production work. Only one set of molding dies and one molding operation are required to fashion all the elements of the roller and shaft assembly. There will be a minimum amount of material handling required since the complete assembly consists of only one article. The roller 11 can be easily and quickly assembled onto the shaft by one simple operation. Flange 18 will retain the roller in its operating position upon the shaft 10 so that separate stop means are not required. a
While a preferred form of the invention has been shown and described, it will be obvious to those skilled 'in the-art that it is not so limited, but is susceptible to various changes and modifications without departing from the spirit thereof, and it is desired that only such limitations shall be 'placed thereupon as are imposed by the prior art or as are specifically set .forth in the appended claims. i
