    Abstract: A guiding guard assembly for a crawler track vehicle is relatively easy to install initially as a "retrofit kit", and can also be easily removed and replaced as needed. Furthermore, the guiding guard does not obstruct idler bearings of the lower run of the track, thus permitting easy servicing. A plurality of transverse supports are secured to the vehicle and disposed transversely of each crawler track and spaced longitudinally apart. Structure for locating a guiding guard member on each side of each crawler track relative to the transverse supports is provided so that a lower face of each guiding guard member is spaced closely to a lower run of each crawler track to resist excessive twisting of the track. Support portions secured to the transverse supports and guard portions secured to the guiding guard members having inclined locating surfaces which cooperate with each other to prevent relative movement between the guiding guard member and the supports when secured together.

    Abstract translation: 用于履带式车辆的导向组件相对容易地最初安装为“改装套件”，并且还可以根据需要容易地拆卸和更换。 此外，导向罩不会妨碍轨道下游的惰轮轴承，从而容易维修。 多个横向支撑件固定到车辆并且横向布置在每个履带上并纵向间隔开。 提供了用于在每个履带的相对于横向支撑件的每一侧上定位导向保护构件的结构，使得每个导向保护构件的下表面与每个履带的下游距离紧密地隔开以抵抗轨道的过度扭转。 固定到横向支撑件的支撑部分和固定到导向保护构件的保护部分具有彼此配合的倾斜定位表面，以防止当固定在一起时导向保护构件和支撑件之间的相对运动。

    Abstract: A ring saw is described which has a novel construction for centering the cutting ring. The ring saw is characterized by a groove in the inner annular surface of the cutting ring. A plurality of rollers are provided which engage the groove in the inner annular surface. The rollers serve to center the cutting ring relative to the saw body while withstanding axial and radial loads placed upon the cutting ring. The construction, as described, serves to increase the capacity of the cutting ring to withstand radial and axial loading.

    Abstract translation: 描述了一种环形锯，其具有用于对准切割环的新颖结构。 环锯的特征在于切割环的内环形表面中的凹槽。 设置有与内环形表面中的凹槽接合的多个辊。 滚轮用于使切割环相对于锯体对中，同时承受放置在切割环上的轴向和径向载荷。 所述的结构用于增加切割环承受径向和轴向载荷的能力。

    Abstract: A portable sawmill with bi-directional cutting circular saws includes a saw support pivotally mounted to a primary support structure for pivotal movement about a pivot axis which is transverse to the direction of movement. Two circular saws are rotatably mounted one above the other on the saw support. A first one of the two circular saws rotates in a first rotational direction and a second one of the two circular saws rotates in a second rotational direction. The teeth on both of the two circular saws are always moving toward a log resting on the log support as the log is being cut. An actuator is provided for selectively pivoting the saw support to invert the positioning of the two circular saws so that the teeth on both of the two circular saws continue to move toward the log being cut upon a change in direction occurring.

    Abstract: A system is provided for installing, retaining and replacing the saw-teeth strip inserts of rotatable, cylindrical feedrolls, without concomitant damage thereto. More specifically, a plurality of circumferentially spaced, longitudinally extending grooves are formed in the body of the feedroll. Each groove is adapted to receive a pair of spaced, parallel saw-teeth strip inserts and maintain them at a predetermined position therein. A wedge is insertable into the groove between the inserts. The wedge is adapted to abut the lower portion of the inserts to clamp them against the groove side walls. A plurality of fasteners, such as allen head screws, are inserted through spaced, aligned bores formed in the wedge and are secured in the groove floor. The fasteners function to releasably secure the saw-teeth strips and wedge within the groove.
