摘要： A device is disclosed to make slits through the bark of a log with a chain saw. The chain saw has a blade with a chain which runs over its extreme free end which is preferably semicircular in shape. Rotatable guide rollers are mounted on both sides of the extreme end of the blade and are preferably coaxial with the semicircular end. The lateral surfaces of the guide rollers face each other and guide rollers in operation hold the chain of the chain saw in contact with a log to be cut for cutting slits of a given depth through its bark.

摘要： A portable core drill adapted for sampling dense mineral specimens or the like by urging a fluid cooled/lubricated tubular drill bit into a dense mineral mass from which a sample is to be extracted is comprised of a drive member for imparting a drilling-effective rotary motion to a tubular drill bit about a longitudinal drill axis and a spindle member for coupling the drill bit to the drive member, which spindle member includes a bit fastening member for receiving and retaining the drill bit concentrically in respect of the drill axis. The bit fastening member, in turn, is comprised of a bit-engaging collet member, received in a collet housing having tapered sidewalls and an end wall, and a rotatable compression member (i) for constricting the collet member about the outer sidewall of the drill bit at or near the proximal end thereof upon rotation and (ii) for engaging an element on the collet member and urging the collet member outwardly of the collet housing upon counter-rotation; whereby the drill bit may be operatively engaged with and disengaged from the bit fastening member by hand rotation and counter-rotation of the compression member, respectively.

摘要： An adapter that converts any normal chainsaw into a winching type towing machine for use by hunters who fell large game such as elk or deer, and must haul their fallen prey over rugged and remote terrain. The adapter replaces a chainsaw chain and guide bar, and bolts into the same position. The adapter comprises a drive chain and housing with a cable guide bar in the front and a tow bar in the rear. The housing contains a drive sprocket connected to a cable drum via a transmission that engages or disengages the drive train. An automatic braking system prevents the cable drum from paying out cable when under a load which may occur when the chainsaw motor is idling and a centrifugal clutch has disengaged the drive power. The adapter folds up into a compact unit capable of being transported anywhere. Additionally, the invention is not limited to use by hunters, but may be used whenever a motorized winching operation is called for.
摘要翻译：一种适配器，可将任何正常的锯条转换成绞盘式拖曳机，供麋鹿或鹿等大型游戏的猎人使用，并且必须将其堕落的猎物拖入坚固耐用的偏远地形。适配器将链锯和导杆取代，并将螺栓拧入同一位置。适配器包括驱动链和壳体，前部具有电缆引导杆，后部具有拖杆。壳体包含驱动链轮，该驱动链轮经由传动装置连接到电缆卷筒，该变速器啮合或分离传动系。自动制动系统防止电缆滚筒在负载时出现电缆，这种负载可能在链锯电机空转并且离心式离合器已断开驱动电源时发生。适配器可折叠成一个能够在任何地方运输的紧凑型单元。此外，本发明不限于猎人使用，而是可以在需要电动绞盘操作时使用本发明。

摘要： Apparatus for splitting logs adapted for use with a power head of a chain saw comprising a screw jack mounted for rotation on the interior of a support channel, the input end of the screw jack being connected through a plurality of reduction gears to a drive sprocket. The screw jack itself is in turn threadably engaged to a travelling axe head conformed for sliding translation within the support channel. A part of the axe head is shaped as a wedge projecting beyond the confines of the channel to advance therealong towards a V-shaped stop bracket. An eliptical cam is mounted for rotation in the thick end of the wedge to be articulated from its narrow alignment to a broad alignment by an articulating lever disposed to advance against one of the legs of the V-shaped stop bracket. As the eliptical cam is thus rotated, expanding the lateral dimension of the axe, separation of the split is achieved.

摘要： This invention relates to an improved portable powered tool for removing bark from living pine trees preparatory to inducing oleoresin flow by known chemical means. This tool utilizes a lightweight, chainsaw-type engine to power a specially designed set of blades partially enclosed in a housing designed to provide multiple guides for producing the type cut necessary to properly prepare a tree for collection of naval stores and to provide a method for discharging debris away from the operator and work area.

摘要： A masonry saw having an engine mounted on one leg of an L-shaped frame with the saw blade being connected to the other leg. A pair of depth wheels are mounted on a guard on the blade and provide a pivot axis for moving the saw between an at rest position and an operational position. The engine is located on the frame in such a position that it will tend to maintain the blade in cutting contact with the work piece in the operational position and in the at rest position maintain the blade out of engagement with the work piece. A modified saw includes a blade remote from the engine and on the opposite side of a frame connected to the engine such that the blade which is misaligned approximately 5* will cut flush against a work piece without interference by any of the structure of the saw equipment.

摘要： A rotary tool attachment for a chain saw motor drive unit, where such unit includes a motor housing and a motor-driven shaft protruding to one side of the housing and mounting a chain saw sprocket. The attachment comprises an elongated support adapted to be secured to the housing with such normal to the driven shaft of the drive unit. A tool-driving sprocket adjacent the end of the support remote from the driven shaft and in the plane of the chain saw sprocket is mounted on a power transmission input shaft which generally parallels the motor-driven shaft. The input shaft extends into a tool-housing assembly mounted on the remote end of the support and is connected through a power-transmitting means with right-angle drive train to a tool-driving head journaled on the tool housing assembly.
