| A timber-working device has a frame, including a feed axis having first and second sides. A drive system independently feeds stems along the feed axis, and has a first rotary drive having a first wheel acting against a first stem on the first side, and a second rotary drive having a second wheel acting against a second stem on the second side. The device has at least two distance measurement devices, each side of the feed axis having an associated distance measurement device. Each generates measurement signals indicative of the length of stems fed along the feed axis, at least one of them indicative of rotation of one of the rotary drives. A processor receives the respective measurement signals, and for each of the first and second stems, determines the length of at least a portion of the stem fed by the drive system based at least in part on the respective measurement signals. | ||||||
| 65 | PICKUP AND ALIGNMENT MECHANISM FOR LOGS AND A METHOD OF USE | US14713679 | 2015-05-15 | US20150343661A1 | 2015-12-03 | Gary Lee Zorn |
| A pickup and alignment mechanism for logs is disclosed along with a method of using the mechanism. The pickup and alignment mechanism includes a frame, a connector and a plurality of L-shaped tines secured to the frame. The plurality of L-shaped tines is grouped into pairs. The pickup and alignment mechanism also includes a pair of side tine. The pickup and alignment mechanism is designed to be removably mounted to a motorized vehicle. All of the L-shaped tines can be hydraulically or pneumatically actuated to remove from between one to six logs from a stacked pile of logs. The one to six logs are then raised above ground level and are aligned relative to one another so that they can be easily cut into smaller piece of firewood by a person with a chain saw. The person with the chain saw will approach the front of the pickup and alignment mechanism and face the motorized vehicle. The pickup and alignment mechanism further includes a plurality of bumpers secured to each pair of L-shaped tines. The bumpers provide a clearance such that the blade of the chain saw can be kept a safe distance away from the frame to prevent damage to the blade. | ||||||

| 71 | Log sawing assembly | US951282 | 1997-10-16 | US5884545A | 1999-03-23 | Thomas E. Hamby, Jr. |
| There is provided a device for sawing logs to a predetermined length which includes a log lead-in support member, a log support frame, a log cutting station and a log collection deck. The log support frame includes a front end, a rear end, opposite sides and supports a conveyor. An upwardly inclined conveyor moves a log lengthwise through the support frame to the log cutting station which includes a stop gate section, a sawing section, and a debris discharge conveyor. The stop gate section is positioned between the conveyor and the sawing section to set the log for proper timing into the cutting station and to align the butts when a plurality of logs is cut at the same time. A cutting station positioned at the front end of said support frame comprising a housing and a chain saw having a cutting bar on said support frame pivotally mounted to rotate 360.degree., whereby when one log is cut to its predetermined length the conveyor automatically moves a further section of the uncut log to a cutting position as the cutting bar makes its rotation. | ||||||

The frame includes a cross member and rearwardly projecting upper and lower structures which slidably mount over the bottom of the load bucket. A top member on the frame bolts to the top of the load bucket. Cable winches further strap the frame to the load bucket. A hydraulic motor, powered by the tractor hydraulic system, rotates a chain saw mounted on the frame. The tractor is driven up to a large hay bale, and the bucket may be adjusted to any height to cut the bale into pieces small enough for easy handling. | ||||||
| 74 | Handle and skid assembly for a chain saw | US23729 | 1987-03-09 | US4726118A | 1988-02-23 | Ronald Mattson; Edward C. Montgomery |
| A handle and skid assembly for attachment to the saw bar of a chain saw. A handle component extends upwardly and rearwardly from the skid assembly and includes a pair of handgrips. The ground engaging skid assembly includes forwardly directed arms with one having an article engaging edge which guides the saw chain diagonally into cutting engagement with the article. An open area defined by the remaining arm receives a portion of the sawed article. The two-piece skid assembly includes protective flanges adjacent the runs of the saw chain. | ||||||
| 75 | Chain saw carriage | US706526 | 1985-02-28 | US4640170A | 1987-02-03 | John A. Bakken |
| A chain saw attachment for mounting a chain saw used to cut reclined logs lengthwise includes a substantially right parallelepiped frame which straddles but does not contact the log. The frame is supported by a supporting surface independent of the log and cooperates with mounting means for rigidly mounting the chain saw in a cutting position. The frame is mounted on feet which permit the frame to be slid along the supporting surface, typically the ground. The mounting means includes two sets of clamping members for gripping opposite ends of a saw bar of the chain saw. Each set is supported by a vertical chain saw support member that is vertically adjustable to vary the level of the chain saw's cutting plane relative to the log. Each chain saw support member mounts a nut that is engaged by a threaded rod, rotation of which causes the chain saw support member and hence gripped chain saw to move vertically. Both threaded rods mount respective sprockets which are interconnected by a drive chain. Rotation of one threaded rod causes simultaneous corresponding rotation of the other threaded rod to permit level height adjustment of the entire chain saw. | ||||||
| 76 | Portable wood cutting device | US511872 | 1983-07-08 | US4553463A | 1985-11-19 | Richard C. Engel |
| A chain saw mounting assembly wherein a chain saw is pivotally mounted at the motor housing end, on a support frame, for pivotal movement in the cutting plane of the saw blade. A throttle actuator on the assembly regulates the speed of the cutting chain between idling speed, when the saw is in its inoperative pivoted position, and an accelerated cutting speed when the saw is in its pivoted operating position. The device is adaptable for mounting on a workpiece supporting table. | ||||||
| 77 | Tree cutting and handling apparatus | US3796242D | 1971-12-20 | US3796242A | 1974-03-12 | ALBRIGHT A |
| A clamp comprising a pair of dogleg jaws pivoted together with opposed double edges defining a variably sized rectangular aperture for transversely engaging a tree at four points on its circumference with each of said double edges. A chain saw is pivoted with the dogleg jaws and between the double edges and adapted to swing between said jaws to cut a tree held therein. The jaws are pivoted to a dogleg boom that itself is pivoted to a carrier link, the respective pivots being horizontally parallel and allowing the jaws to pivot over 180* and the boom less than that. The carrier link is vertically pivoted to a power train. Opposed shearing plates are fixed in the respective angles of the dogleg jaws on one only of the opposed double edges for shearing small trees. Hydraulic cylinders and pistons are adapted to swing the jaws and chain saw about their common pivot, the free ends of the jaws nesting in closed position. Additional hydraulic cylinders and pistons are adapted to swing the boom and clamp about their respective pivots. An hydraulic motor drives the chain saw in endless rotation. A flow divider mounted in the hydraulic power lines to the motor and chain saw regulates the speed of the chain saw swing inversely with the size of the rectangular apperture defined by the dogleg jaws.

| 78 | Log slasher | US3771395D | 1968-06-28 | US3771395A | 1973-11-13 | HEIMERL C |
| A log slasher includes an elongated log receiving bunk and a saw assembly movable longitudinally along the bunk to saw logs supported in the bunk into shortened lengths. The saw is pivotally supported at one end on a traveling trolley for movement with the trolley along the bunk and in a vertical plane toward and away from the bunk. A guide moves with the saw to hold the saw against whip as the saw is moving into, and away from, a cut. A lift crane lifts logs into and out of the bunk and includes clam fingers having opposite angled surfaces adjacent the free ends thereof for engaging logs of different diameter. The trolley drive and that for moving the saw toward and away from the bunk are carried on the trolley and an articulated arm assembly, extendible and contractible in response to trolley movement, supports the power supply conduits in a compact arrangement throughout the range of movement of the trolley and saw.
