WILLIAM H. COOPER, OF SEATTLE, WASI-IINGTGN.
Specification of Letters Patent.
Application filed April 9, 1914. Serial No. 830,865.
To all whom it may concern Be it known that 1, WILLIAM H. Coornn, a citizen of the United States, and a resident of Seattle, King county, Washington, have invented certain new and useful Improvements in Rollers, of which the follow-' ing is a specification.
This invention relates to rollers, and more especially to such devices in the use of which it is necessary to shift a body, which is supported upon a roller, in the direction of the length of the roller: for example, such as the shifting of the ends of a cant upon the rollers usually provided to support and convey it to the edger. That is to say, after the cant has been slabbed approximately square it is disposed upon rollers whose axes are at right angles to the saws of the edger and the cant must, of course, be straightened so as to lie about parallel with the vertical plane of the edges of the edger saws, and to do this it has been heretofore usual in the art, so far as I am aware, to employ two men because of the excessive resistance caused by the friction of the cant upon the rollers. I accomplish this end by a peculiar arrangement and combination of the parts, as will be more fully hereinafter described and explained, illustrated in the accompanying drawings and pointed out in the appended claims.
In the drawings, Figure 1 is a rather diagrammatic view of a form of edger, together with its log carrier, ways therefor, etc, and showing my improved roller applied thereto. Fig. 2 is an enlarged fragmentary side elevation of the said roller and its shaft, partly in section. Fig. 3 is a similar View in end elevation.
Referring now more particularly to the drawings, reference numeral one (1) designates the frame of an edger: 2, its roller: 3, its saws: 4, the spindle upon which the said saws are mounted: 5, the pulley around which is the driving belt 6. 7 indicates the frame work for the rollers 8, 8 and 8 9 indicates conveyors which may have upon them studs such as indicated at 10, which perform the usual function of such studs, viz: to convey the log 11 from its carrier 12 across to the rollers upon the frame 7, after the said carrier has been advanced along its ways 12 to a point about parallel with a frame indicated at 12 upon which are rollers 12. 13 indicates holding dogs upon the said carrier.
1% indicates a band saw: 15, a frame upon which is mounted the shaft 16 of the wheel 16 which actuates the said band saw.
All of the construction, above briefly described, with the exception of the rollers 8", may beef usual form, as my invention relates solely to said rollers and the edger construction has been shown merely to make more plain a particular condition in which the said rollers are useful, it being distinctly understood of course that other analogous uses could be made of the said rollers, such for example as the handling of bar steel and the like. In the construction described the roller 8 is the only live one of the series, and it is normally slightly below the horizontal plane of the other rollers upon the frame 7, there being a treadle such as indicated at 17 by means of which the said roller may be raised and lowered, and the chain 18 constantly causes the said roller to rotate, as will be understood.
A cant which has been previously cut out of a log and conveyed, by means of the con veyers 9, to the rollers 55 and 8", seldom disposes itself parallel with the plane of the edger saws 3 and this is, obviously, necessary before the cant is advanced against the said saws: thus one end or the other of the cant must be moved in the direction of the length of the roller, and such movement, of course, is resisted by the friction between the cant and the rollers. To overcome this, I provide wheels or sub-rollers 18, which are arranged along the rollers 8", and the axis of each of the sub-rollers is perpendicular to a plane passing through the longitudinal axis of the main roller and the center point of the subroller, as plainly seen in Figs. 2 and 3. The said wheels project slightly above the periphery of the said rollers so as to contact directly with the cant and when the latter is moved in the direction of the length of the rollers the said wheels are caused to revolve and thus relieve the friction which would otherwise exist. These wheels may be arranged in any suitable manner, except that the axis of each wheel must be at a right angle to a plane passing through the longitudinal axis of the main roller and the center point of the wheel. I have, however, provided a very convenient manner of mounting the said wheels, which I will now describe.
19 indicates a core which is longitudinally bored throughout to receive the shaft 20, and arranged around the said core are segmental members 21' which are each suitably bored at intervals to revolubly receive the stems 22 of the wheels 18, the said wheels being in staggered relation to eachother, as plainly shown, so as not to unduly weaken the members 21. Both ends of each of the said members 21 may be recessed to receive the annular flanges 23 of the caps 24, one of which is positioned at either end of the roller and secured thereto by means of machine screws 25.
While I have shown and described a particular form of embodiment of my invention, and set forth in particular one of its uses, I am aware that many minor changes in the construction shown will readily sug gest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I therefore desire to avoid being limited to the exact form shown and described.
What I claim as new and desire to protect by Letters Patent is 2- 1. In an article of the class described, the combination with a main roller, of subrollers mounted upon the said main roller and having their axes perpendicular to a plane passing through the longitudinal axis of the main roller and the center point of the subroller.
2. In an article of the class described, the combination with a main roller having copies of this patent may be channels along its periphery which are parallel to the axis of the roller, wheels mounted Within the said channels and having their axes at substantially right angles to a plane passing through the longitudinal axis of the main roller and center point of the subroller.
3. In an article of the class described, the combination with a main roller having a core portion and segmental members remov ably arranged around the said core portion and in spaced relation to each other, means for holding the said members in place, wheels mounted between the said segmental members and having their axes at substan tially right angles to a plane passing through the longitudinal axis of the main roller and the center point of said wheels.
l. In an article of the class described, the combination with a main roller comprising a core portion, segmental members arranged around the said core portion and in spaced relation to each other, a plurality of wheels within the spaces between the said segmental members and having their axes at sub stantially right angles to the plane passing through the longitudinal axis of the main roller and the center point of the said wheels, a cap for each end of the roller and means for securing the ends of the said segmental members to the said cap whereby the said members are held in place.
