AUSTIN 1). SHAVER, OF BLOUNTVILLE, TENNESSEE.
LOG-TURNER.
SPECIFICATION forming part of Letters Patent No. 776,949, dated December 6, 1904. Application filed August 1'7, 1904. Serial No. 221,118. (No model.)
To all whom it nuty concern:
Be it known that I, AUs'rIN D. SHAVER, a citizen of the United States, residing at Blountville, in the county of Sullivan, State of Tennessee, have invented certain new and useful Improvements in Log lTurnerS; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to sawmills, and more particularly to log-turners therefor, and has for its object to provide a log-turner which may be operated by the power operating the sawmill and which will turn the logs to bring them into the desired position.
Other objects and advantages will be apparent from the following description, and it will be understood that modifications of the specific construction shown may be made and any suitable materials and proportions may be used without departing from the spirit of the invention.
In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an end view of the present invention, showing it in the act of turning a log. Fig. 2 is a side elevation of the log-turning mechanism. Fig. 3 is a section on line 3 of Fig. 2. Fig. 4c is a top plan view of Fig. 2. Fig. 5 is a longitudinal section taken on line 5 5 of Fig. 3. Fig. 6 is a detail perspective view of the guide-frame and adjacent parts of the mechanism.
Referring now to the drawings, there is shown the usual arrangement of track over which the carriage 9 is arranged to travel in the usual manner. Mounted longitudinally between the rails and parallel therewith is a shaft 10, having a bevel-gear 11 at one end, and disposed transversely of the shaft and adjacent to the bevel-gear is a shaft 12, and splined upon this shaft is a sleeve 13, which is slidable. longitudinally thereof and which has oppositely-directed friction-gears 14 at its end, and this sleeve is slidable, as mentioned, to bring its gears alternately into and out of engagement with the bevel-gear 11 to revolve the shaft in opposite directions, the shaft 12 being connected with the source of power operating the sawmill for rotation thereby.
The sleeve 13 is provided with a peripherally-grooved collar 15, and in this groove are engaged the spaced members of a yoke 16, carried by a lever 17, which is connected by other rods 18 and 19 and an intervening bellcrank lever 19 to a hand-lever 20, by means of which the sleeve may he slid upon the shaft 12 to bring either of its gears into engagement with the gear 11 or to bring them both out of such engagement, the lever 20 being provided with a dog 21, arranged for engagement of a notched segment 22 to hold thelever, with the sleeve, in different positions.
A guide-frame 23 is provided which is rectangular in shape and which has a central opening 24:, and upon one face this guideframe is provided with enlargements 25 adjacent to its edges, and these enlargements have alining openings 26 therein, with which the shaft 10 is revolubly engaged, the guideframe 23 extending above and below the shaft and being offset laterally therefrom, as shown.
Formed vertically through the upper and lower side portions of the guide-frame and opening through that face of the frame which lies in the direction of the shaft 10 are alining guide-passages 27 the ends of which open through the outer and inner edges of the upper and lower side portions of the frame, as will be readily understood. The face of the guide-frame which, as mentioned above, lies in the direction of the shaft 10 is indicated at 28 and slidably disposed in the guide-passages 27, and lying with one of its faces flush with the face 28 of the frame is a feed-block 29, having a pair of longitudinally-extending spaced racks 30 upon its exposed face, and mounted upon the shaft 10, between the enlargements 25, are a pair of spaced pinions 31, which engage the racks 30 to move the feed-block 29 in the passages 27. Extending in the direction of the shaft 10 from the feed-block 29 are a plurality of log-engaging pins 52, which lie between the racks 30.
Formed upon the outer end face of one of the enlargements 25 is a cone-shaped extension 34, havingacone-shaped recess there in opening through the outer face of the extension at its major end, and this recess lies concentric with the shaft 10, the extension 34 forming one member of a friction-clutch, the other member of which is formed by a frustoconical block 36, which is slidably mounted upon the shaft 10 and which has a sleeve 37 secured thereto and splined upon the shaft. The sleeve 37 has a peripherally-grooved'collar 38 thereon, with the groove of which there is engaged a yoke 39, carried by a rockshaft 40, and this rock-shaft is provided with a hand-lever 41, disposed adjacent to the handlever 20 and by means of which the rockshaft may be operated to move the block 36 into and out of frictional engagement with the inner face of the extension 3A, the handlever I1 being provided with means for holding it, with the block 36, in either of said positions.
In use a log is disposed upon the carriage 9, and the carriage is moved to lie above the feed-block 29 and the adjacent parts of the mechanism, and it will be understood that the feed-block 29 and guide-frame 23 lie at an angle to the perpendicular and in a plane extending at the side of the log opposite to the direction in which it is to be rolled. The lever 20 is now operated to bring one of the gears 14 into engagement with the gear 11 to revolve the shaft 10 in the direction of the log, which also causes the feed-block 29 to move upwardly, as will be readily understood. At the same time the hand -lever ll is operated to bring the two clutch members into frictional engagement, which revolves the guide-frame 23 with the shaft 10 and brings the pins 32 into engagement with the log, and it will thus be seen that the upward movement of the feed-block causes the log to roll. The block 36 is applied with just sufficient power to hold the frame 23 with the feed-block in engagement with the log, though permitting the block 36 to slip within the extension 34:.
'VVhen the operation is completed, the handlever 20 is moved to bring the other gear 14: into engagement with the gear 11, which revolves the shaft 10 in the opposite direction, thus moving the feed-block and the guideframe to their original positions, the block 36 having been moved into inoperative position, as will be readily understood.
hat is claimed is- 1. A log-turner comprising a revolublymounted shaft, a guide-frame loosely mounted upon the shaft, a feed-block slidably mounted in the guide-frame, connections between the shaft and feed-block for movement of the latter longitudinally in the frame, means for moving the guide-frame at times with the shaft, and means for revolving the shaft in either direction to bring the feed-block into or out of position to engage a log disposed upon the carriage and to move the feed-block in the frame.
2. A log -turner comprising a revolublymounted shaft, a guide-frame loosely mounted upon the shaft, a feed-block slidably mounted in the guide-frame, connections between the shaft and the feed-block for movement of the feed-block in the frame when the shaft is revolved, means for revolving the shaft in either direction, and means for revolving the guideframe with the shaft to bring the feed-block into or out of position to engage a log.
3. A log-turner comprising a revolublymounted shaft, a guide-frame loosely mounted upon the shaft, afeed-block slidably mounted in the frame, racks carried by the feed-block, gears carried by the shaft and meshing with the racks for movement of the feed-block in the frame when the shaft is revolved, said guide-frame having a recess therein surrounding the shaft, a clutch member slidably mounted upon the shaft for rotation therewith and arranged for movement to lie at times in frictional engagement with the walls of the recess to revolve the guide-frame with the shaft, and at times to lie out of such position, and means for revolving the shaft in either direction to bring the feedblock into and out of position to engage a log.
In testimony whereof I afIiX my signature in presence of two witnesses.
