Los-ROLLING DEVICE.

. Application led June 7, 1913.

To all whom t may concern Be it known that I, ALLAN PAYNE, a subject of the King of Great Britain, residing at Courtenay, in the Province of British Columbia and Dominion of Canada, have invented certain new and useful Improvements in Log-Rolling Devices, of which the following is a specification. Y

This invention relates to log-rolling devices and more particularly to a device employed in connection with log carriages used in saw mills or the like for the turning of the log.

The primary object of this invention is the provision of a device of this nature which will materially decrease the amount of labor necessary for the turning of logs while upon the carriage of the saw mill and further to provide a device of this nature which will turn the logs in any desired direction without necessitating any manual adjustment of the device.

Figure 1 is a side elevation of one of the improved log-rolling devices showing one of the hooks of the same secured to a log, the log being shown in dotted lines; Fig. 2 is an enlarged side elevation showing the parts of the log-rolling device in a different position to that shown in Fig. 1;` Fig. 3 is a longitudinal sectional view through Fig. 2; Fig. 4 is an end view of the device; and Fig. 5 is a cross-sectional view through the logrolling device. Fig. 6 is a perspective view of my improved log rolling device showing to advantage the frame supporting the same.

Fig. 7 is an end elevation showing the device in another position.

Referring more particularly to the drawings, 1 designates the cam-shaped casing which is rigidly mounted upon a shaft 2 by means of a key 4 and which has a camshaped member 3 disposed upon one side thereof and loosely mounted upon the shaft 2.

The shaft is supported in bearings 2 carried by beams 3, said beams forming a part of a frame work of any practical design, said shaft 2 being mounted adjacent to the log deck of the saw mill and disposed at one side of the saw, the vobject of the device being to rotate the log for each cutting operation. Rotation of the shaft y2 is accomplished by means of a sprocket 5 0 having a chain 51 passing thereover as shown to advantage in Fig. 6.

The casing 1 has a hook member 4 pivotally connected thereto as at 5. The hook member 4 has its outer end 6 bent inwardly substantially at right angles to the portion 7 of the member v4 and sharpened as is clearly illustrated in Figs. 1 and 3 of the drawings. This hook member 4 is provided forthe turning of the logs toward the casing 1 or to the right-as is illustrated in Fig. 1, a log being shown in dotted lines. The hook member 4 is pivotally mounted upon the casing 1 at 5 by means of a pin 8 which has an arm 9 formed integral therewith and eX- tending inwardly into the casing 1. The arm 10 which has one end thereof enlarged as at 11 is pivotally connected to the arm 9 at '12 and forms a means for the operating of the hook member 4. v

The cam member 3 is held in a desired position by means of a link 39 connected to a pin 40 mounted on thecam member 3 and operated vertically by means of a bell crank lever 41. Each cam member 3 is provided Vwith this mechanism and each of the bell crank levers is simultaneously actuated so as to insure synchorism in the operation of the device.

The cam-.shaped member 3 which is loosely mounted upon the shaft2 has a notch 14 formed therein, which notch 14 is so shaped as to receive the enlarged end 11 of the arm 10 when the cam 3 moves so that the enlarged end 11 of the arm 10 is engaged by the notch 14, as is shown in Fig. l of the drawings.

Then it is desired to operate the hook member 4, the casing 1 and the shaft 2 are rotated, by means of the sprocket 50 and chain 51 until the arms 9 and 10 are in a position as is shown in Fig. 1. The cam member 3 being loosely mounted upon the shaft 2 will not rotate therewith by virtue of its connection with the lever 41 and consequently the enlarged end 11 will, upon rotation of the casing 1 and the shaft 2, seat l itself within theV notch 14. This will stop movement of the lever 10 in unison-with the casing 1 and upon further movement or rotation of the casing 1 and the shaft 2, will by means of the pivoted connection between the same and the arm 9, force the hook member 4 outwardly and cause the sharpened end 6 of the same to engage the log 15. After the tsharpened end 6 of the hook 4 has engaged the log reversing the rotation of the shaft and casing will draw the log 15 toward the casing 1 or to the right as is indicated in dotted lines in Fig. 1 of the drawings. A roller 16 is revolubly mounted upon the casing 1 and is engaged when the log is drawn toward the casing 1, by the hook 4 and rests on the casing 1 and ro-ller 16. The log in this position is practically off the carriage and resting upon the casing 1, with a roller 16 receiving most of the weight. The log slides fromv the roller 16 on to the carriage when the casing is turned toward the log.

A plurality of straight bars 20 which have sharpened points 21 formed upon their outer ends are also mounted within the casing 1 and have rollers 22 revolubly mounted, by means of the pins 23 upon their inner ends. The rollers 22 are disposed within the interior of the cam-shaped member' 3 and engage the inner surface of the sides of the same as is clearly illustrated in Fig. 3 of the drawings. A collar 24 is mounted upon the shaft 2 within the cam-shaped member 3 and has the rollers 22 engaging the outer surface thereof when the bars 20 are in an inoperative position.

1n Fig. 7 the casing 1 is shown in the position which the same occupies when the radial arms 20 are being operatively engaged with a log. It will be seen in this view that the arm 10 is resting upon an abutment 10', the said abutment 10 preventing the loose swinging and dangling of the arm- 10 when inoperative, and the camr member 3 is in the position shown in Fig. 7.

A member 25 is pivotally mounted upon a pin 26 within the cam-shaped member 3 and has its end 27 curved so as to fit snugly against the outer surface of the collar 24. The member 25 is normally held in position, having its curved end contacting with the outer surface of the collar 24, by means of a flat spring 2S which has one end thereof secured to the cam-shaped member 3 and the other end engaged by a pin 29 which is mounted within the member' 25. A member 30 is rigidly mounted upon the pin 26 and operates in unison with an arm 31 which is also mounted upon the pin 26 and disposed upon the exterior of the cam-shaped member 3. The outer end of the arm 31 has a slot 32 formed therein in which is seated a pin 33. The pin 33 has a plate 34 rigidly connected thereto, which plate, at certain times, forms a covering for the notch 14 and prevents the enlarged end 11 of the arm 10 fromv entering the notch 14. When the shaft 2 and casing 1 arev rotated in a direction so as to cause the hook members 4 to operate the plate 34 and the arm 31 are operated or moved so as to allow the enlarged end 11 to enter the notch 14. This operation causes the member 30 to move against the side of the member 25 and move the saine into en-gagement with the outer edge of the cam, thus preventing the rollers from operating when the casing is turned in any direction. r1`he spring 23 engaging the member 25will, in connection with the pin 29, force the member 25 back to its proper position directly after the rollers 22 have been passed therebetween.

`When the shaft 2 and the casing 1 are rotated in the direction opposite to that for operating the hook member 4, the spring 23 engages the member 25 and holds the same in a closed or inoperative position and at the same time causes the member 30 and the arm 31 to form a closure for the slot within the cam shaped member 3 at 14. This causes the rollers 22 to move outwardly along the outer edge of the member 25, as is clearly shown in Fig. 3 of the drawings and causes the bar 2O to move outwardly through an opening 36 in the casing 1 and engage the log 15 from the under side. This will turn the log 15 to the left or away from the casingv 1 and the shaft 2.

As hereinbefore set forth 1 have provided a sprocket 50 mounted upon the shaft 2 and having the ychain 51 operatively engaged therewith for rotating the shaft 2, and when it is desired to throw the arms 4 outwardly into engagement with a log, the cam members 3 are retained in the position shown in Figs. 1 and 6. The shaft 2 is now rotated to the left, the arm 10 engaging in the cut out portion 14 in the cam 3. Continuing to rotate the cam shaped members 1 will cause the arm 4 to swingoutwardly relative to the cam shaped members 1 by virtue of the stationary f connection of the same through the medium of the arm 10 with the cam member 3. 1t is thought that its operation will be clear to those skilled in the art. 1n order to remove the plate 34 from the path of the arm 10 the L said plate is connected to and carried by the arm 31 as hereinbefore set forth. rl`he arm 31, as shown to advantage in Fig. 3, is connected to the member 25, and when the said member 25 is in the position shown in Fig. 3 the arm 31 will be in the position shown in Fig. 7 that is, seating in the cut-out portion 14 of the cam 3. The plate 34 remains in this position as long as the arms 2O are in use, the member 25 serving to force one of the arms 20 outwardly beyond the periphery of the cam shaped member 1 as shown to advantage in Fig. 3. lVhen the plate 34 is seated in the cut-out portion 14 it is impossible vfor the arm 10 to engage in the said cut-ont 'portion' 14 and therefor the hook members 4 will not be forcedout from the cam shaped members 1 when the arms 20 are in use.

The function of the rollers 22 and the arms 20 has been hereinbefore set forth and it is not thought that it is necessary to dwell upon this further.

In practical fields, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.
