ROLLER LOGGING CONVEYER.
Application filed October 15, 1926. Serial No.141,839.
rlhis invention relates to conveyers used in the logging industry and has for its ob-v ject the provision of a novel roller adapted to be constructed of any suitable material and of any preferred size, the roller having its opposite end portions grooved `at different pitches for the purpose of handling logs, logs of large diameter being handled by the groove at one end, or accommodated therein, and logs of small diameter being accommodated by the smaller groove at the other end.
An important object is the provision of a roller of this character which will be simple and inexpensive to manufacture, positive in action, efficient and `durable in service, and a general improvement inthe art.
IVith the above and other objects and advantages in view, the invention consists in the details of construction, and the ar ange ment and combination of parts to be here- `inafter more fully described and claimed,
and illustrated in the accompanying drawings, 1n which: i
Figure 1 1s a plan view showing a plurality of the rollers journally mounted with` in a. suitable supporting structure, and
Figure 2 is a detail perspective view of one of the rollers alone.
Referring more particularly to lthe drawings, the numeral ltlxlesignatcs the roller, as a whole. This roller may be of any desired length, diameter and material, and the shape may also be varied at least within certain limits. roller is represented as having trunnions 11 yat the ends thereof, it being however conceivable that these trunnions need not be formed integrally with the body of the roller but might be formed as the end portions of a suitable shaft passing axially through the entire roller structure. The purpose of providing a shaft or trunnion` as the case may be, in order to permit theroller, or any number thereof, to be journally mounted within a supporting structure or frame, for instance, as the longitudinally extending bar members 12 shown in Figure 1.
The essential feature is the specific shape i or formation of the rollers and referring'to Figure 2 in particular, it will be observed that one end portion 1b is relatively long as compared with the opposite end portion 14, though both are shown as being of the same diameter at the ends. The roller portion 413 is grooved as clearly indicated, as is In the present instance this the end portion 14 though it will be observed that tlie radius of curvature or the pitch of the inclined portions of the roller elements or portions 13 will be much less abrupt than the curvature or pitch of the end portion 14 inasmuch as the first named portion is intended to accommodate or handle logs of large diameters while the other is intended to handle logs of unich less diameter.
From the foregoilig description and a study of the drawings, it will be apparent that I have thus provided a very simple and inexpensive roller construction which willv be of great advantage when used, for instance, in connection with handling logs in the lumber industry. It is thought that the construction, operation and advantages will be readily apparent to one skilled inthe art without further explanation.
While I `haver shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to makeV such changes in the form, construc- -tion and arrangement of parts as will not depart from the spirit of the invention or Y, the scope of the subjoined claims.
Having thus claim:
1. A roller for logging purposes, coinprising an elongated body having trunnions at its ends providing means whereby it may be mounted for turning movement, the op. positie end portions of the roller being formw described the invention, I
`ed with curved grooves, the grooving and curvature at one end being muchV lnore abrupt thanat the other end in order to correspond to and accommodate logs of widely different diameters. i
2. In a logging conveyer structure, a plurality of rollers arranged in series, each including an elongated body provided with trunnions at its` ends and having its opposite end portions formed with roller structures, one having a curvature and pitch much more abrupt than that of the other, the difference in curvature and pitch permitting the two different end portions to accommodate and handle logs of widely dif` ferent diameters, the different end portions being connected by a reduced trunnion portion.
In testimony whereof I affix my signature.
