A joint for securing two workpieces together. The joint includes a projection and a complimentary slot for receiving and securing the projection therein. The projection includes spaced-apart convex sidewalls extending outwardly from a first workpiece, and an end wall connecting outer ends of the sidewalls. The slot is formed in a second workpiece, and includes an opening for receiving the projection therethrough and a pair of spaced-apart concave sidewalls which define lateral boundaries of the slot.

The present invention relates to a brush cutting head for a brush cutter. The brush cutter head includes a cylindrical support body that has a first end, an opposed second end and an intermediate portion extending therebetween. The intermediate portion has a curved surface that defines the circular cross-section of the cylindrical support body. A plurality of collars is mounted to the cylindrical support body at spaced intervals along the intermediate portion. Each collar extends radially from the curved surface of the cylindrical support body. Additionally, each collar cooperates with an adjacent collar to define a mounting station between the adjacent collars. The brush cutter head further includes a plurality of cutting tooth assemblies carried on the outer surface of the cylindrical support body. Each cutting tooth assembly has a cutting tooth for placement within the mounting station and a mounting assembly engageable with the adjacent collars to secure the cutting tooth in the mounting station.

The cylindrical shank of a rotatable tool is retained in the cylindrical bore of a tool holder by a retainer that engages an annular groove on a portion of the shank of the tool that extends outward of the rear surface of the tool holder. The tool has an axial bore in the distal end of the shank. The retainer has a pair of spaced ridges that engage the annular groove on the shank and a panel that extends across the distal end of the shank. The retainer is held in place by a pin extending through the panel and into the bore in the distal end of the shank.

A cutting tool holder, a cutting bit, and a retainer maintaining the cutting bit at a prescribed position relative to the tool holder. The cutting bit is received in a slot located in a first lateral surface that extends through the top surface. The retainer is received in an opening included in the first lateral surface that intercepts the slot. The retainer includes a planar tapered surface that contacts an upwardly and laterally facing oblique surface on a lower end of the cutting bit to hold the lower end of the cutting tool in contact with a lower surface of the slot.

A rotary cutting machine comprises a circular rotating element having a transverse axis of rotation and which is mounted to the rotary cutting machine for rotation about the axis of rotation. A plurality of cutting teeth are mounted to the circular rotating element at spaced apart locations about its circumferential periphery. The cutting teeth are reversible and removably fastened to the circular rotating element. Each cutting tooth includes opposed first and second cutting faces spaced apart by lateral surfaces extending therebetween. The first and second cutting faces define at least four of the cutting edges thereon, such that the cutting teeth are selectively mountable on the circular rotating element in any one of at least eight different positions, each of the positions providing a different one of the cutting edges in the operable cutting position.

A brush cutting head having internally housed drive and bearing assemblies which can be easily attached / detached from the brush cutter housing without having to dismantle the drive assembly for improved productivity. The brush cutting head includes a hollow support body, a drive and bearing assembly housed at least partially within the hollow of the support body, a drive block mounted to extend within the hollow of the support body, and a motor provided with a torque transmitting driveshaft.

The present invention relates generally to brush cutting heads, and more specifically, to protective guard members for cutting tooth assemblies mounted on brush cutting heads. A brush cutting head includes a support body having a first end, an opposed second end and an intermediate portion extending therebetween. The intermediate portion has an outer surface. A plurality of collars is mounted to the support body at spaced intervals along the intermediate portion with each collar extending outwardly from the outer surface. The brush cutting head further also has a plurality of cutting teeth assemblies carried on the outer surface of the support body. Each cutting tooth assembly is associated with at least one collar. Also provided is at least one guard member for protecting at least one cutting tooth of the plurality from impacts with hard objects. The at least one guard member is carried on one of the collars with at least a portion thereof projecting beyond the outermost edge of the one collar. The at least one guard member has an outermost margin which defines a protective envelope that at least partially encompasses the at least one cutting tooth.

A cutter head assembly for a wood planing machine includes a shaft, a plurality of cutter-mounting sleeve modules sleeved on the shaft, and a plurality of cutter modules respectively secured to the sleeve modules such that cutting edges of the cutter modules extend beyond outer wall surfaces of the sleeve modules. An angularly variable positioning mechanism includes an axially extending guiding member disposed on the mount segment, and a plurality of axially extending guided members disposed on inner wall surfaces of the sleeve modules to mate with the axially guiding member. By virtue of fitting engagement between the guiding member and a selected one of the guided member of each sleeve module that are sequentially sleeved onto the shaft, the cutting edges together define a cutting contour line that winds around the shaft.

A milling disk for a floor machining appliance has a plurality of mounts for holding interchangeable plate-like milling tips, the milling disk being driven for rotation by the floor machining appliance and being held substantially parallel to the substructure to be machined so that the milling tips may bite into the substructure and remove matter from the surface thereof. The milling tips are constituted by ceramic cutting tips.

A stump grinding wheel includes a wheel disc, which includes multiple recesses formed about its periphery. A peripheral cutter assembly is disposed in each one of the recesses and is mounted on the wheel disc. Multiple side cutter assemblies are mounted on the wheel disc, and each one includes a first pocket and a second pocket. The first pocket is disposed on one side of the wheel disc and the second pocket is disposed on the other side of the wheel disc, and a wear pad is formed adjacent a selected end of each pocket. A cutting tooth is received in aligned openings formed in the first pocket, the wheel disc, and the second pocket. A nut threadably engages the cutting tooth of the side cutter assembly to secure the tooth to the first and second pockets, and to secure the pockets to the wheel disc.

A clamping device has a chuck (1) and a releasable workpiece support (22) in which the chuck (1) has a clamping mechanism for fixing the support (22). The clamping mechanism also has a number of clamping elements which are designed as sliding elements. The workpiece support (22) has a clamping surface (28a) extending along its lateral surface (26) on which the sliding elements are placed during tight clamping.

A cutting tooth for use with a stump cutting apparatus wherein the cutting tooth has a removable and replaceable cutting bit. The cutting bit is removably and nonrotatably secured to a head of an elongated shank with the shank secured to a mounting block or pocket of a stump cutting tool. A support member having an indexing surface is also removably and nonrotatably secured to the head of the elongated shank. Accordingly, the support member enables indexing the cutting bit to expose and use a plurality of cutting edges located on the periphery of the cutting bit.

The invention relates to a barking device comprising a barking arm (1) and a barking tool (2) which is mountable in a tool seat of the barking arm. The barking tool comprises a convex mounting surface (13), while the seat surface (7) of the barking arm is concave. The barking tool is, with the aid of a connecting means, mountable in the tool seat and displaceable by rotating displacement. The connecting means comprises a screw (18) and a sleeve-like nut (21). The head (20, 23) of one of the connecting means parts (18, 21) is designed to prevent displacement and rotation.
