| 194 | Precision angle cutting attachment for chain saws | US433941 | 1995-05-02 | US5713134A | 1998-02-03 | Patrick Lane Stevens |
| An attachment for a chain saw that allows the angle of a cut to be controlled with great precision. The attachment consists of a rigid, rectangular guide frame with an open window construction. An approximately U-shaped blade mount is hingably attached to the guide frame, thus allowing a saw blade to be inserted through the open window of the guide frame and mounted onto the blade mount. The blade mount, and thus the attached saw blade, can move in an arc with respect to the guide frame, and the attachment includes a selecting means by which to determine the angle between the blade mount and the guide frame and a tightening means by which to secure the blade mount and guide frame in the desired position. An additional feature is a directing fence so as to control the direction of a cut. The fence consists of a first and a second bar that are hingably mounted to one another and can thus be rotated and secured so that any desired angle is set between them. The fence is positioned on an edge of the workpiece so that one of the bars rests along the top edge, and the other bar extends along the side edge at the selected angle. The guide frame is then aligned with the angled bar and kept in sliding contact with it as the chain saw blade cuts through the workpiece. | ||||||

| An attachment for a chain saw (100) includes two elongated members (4D) mountable on the opposite faces of the chain guide (102). Each member (4D) has an elongated center portion (6D) configured to be secured to the chain guide (102) in a position closely adjacent to the corresponding face thereof. An angled portion (30) extends laterally outwardly from the outer edge of the center portion (6D). A plurality of spaced apart teeth (12D) project from the angled portion (30) substantially parallel to the chain guide (102) over and beyond the chain (104). Each tooth (12D) has, on an upstream edge thereof, a surface (18D) angled laterally outwardly in an upstream direction to help retain the chain on a path around the periphery of the chain guide (102). The angled surface (18D) is preferably formed by bending the edge of a substantially flat tooth. The surface (18D) preferably extends along the tooth (12D) from its pointed tip portion (36) to and along a radiused junction (34) with the angled portion (30) of the elongated member (4D). | ||||||
| 196 | Chainsaw attachment | US631146 | 1996-04-15 | US5669145A | 1997-09-23 | Harold O. Skripsky |
| An attachment for chain saws that provides a pivot point for better cutting leverage and control especially when cutting small tree branches or limbs. The attachment is installed on both sides of the saw chain and has two or more angularly and outwardly extending prongs that pull the limbs into the chain so that they can be more easily cut. Spacers between the chain bar and the attachment provide for proper clearance for the chain and allow easy installation and removal of the attachment. The attachment also is reversibIe so that it can be used for creating a straight cut using a straight edge as a guide and for controlling the depth of a cut when cutting a kerf in timbers or logs. | ||||||
| 197 | Chain saw with reinforcing and cutting attachment | US323371 | 1994-10-11 | US5511315A | 1996-04-30 | Ruben N. Raya |
| An attachment for a chain saw is provided for adapting the saw blade to cut small diameter branches without weakening the saw blade holder or causing undesired kickback or jamming. The attachment comprises a pair of L-shaped cutting bars attached on both sides of the saw blade holder and spaced sufficiently apart to accommodate the width of the cutting chain. The cutting bars comprise a support portion and an angle portion, the support portion positioned approximately midway along the length of the saw blade holder and extending along a line parallel to the longitudinal axis of the saw blade holder. The angle portion of the cutting bars projects beyond the lower edge of the blade, and forms a wedge shaped angle or bight between the saw blade attachment and the cutting chain. During use, small diameter branches are drawn towards the forwardly projecting angle portions, and are compressed into the wedge shaped angle or bight by the cutting chain of the chain saw, where the teeth of the saw cut through the branches. The bight area assists the operator to align and guide the branches into a stable cutting position away from the hands and face of the user, thereby stabilizing the branches and saw with respect to each other, and reducing the tendency for undesired jamming and kickback. Removal of the cutting bars enables the chain saw to be used in a normal mode for cutting large sized branches, logs, and the like. | ||||||
| 198 | Chain saw depth cutting gauge | US278890 | 1994-07-22 | US5435065A | 1995-07-25 | Daniel G. Raczykowski |
| A bar mounted chainsaw cutting depth gauge is described on a chain saw cutting bar for selectively covering a length of the chainsaw bar and bar tip. The gauge includes an elongated base sleeve mountable to the chainsaw bar to cover a portion of the chainsaw bar. A fastener releasably and securely mounts the base sleeve to the chainsaw cutting bar. An outer housing is slidably received over the chainsaw bar and base sleeve for sliding movement along the length thereof from a first or extended position wherein the bar tip is encased within the outer housing and a second or retracted position wherein the bar tip is exposed outward from the outer housing. The outer housing includes an outer tip with a slit formed therein for permitting passage of the chainsaw bar therethrough. A spring is operatively mounted between the base sleeve and outer housing to constantly, yieldably bias the outer housing toward the first extended position. A selected depth of cut is determined by either a pin placed between the housing and base sleeve to set a maximum or minimum cutting depth, or a clamp is used to lock the housing at a selected cutting depth. | ||||||
| 199 | Feed mechanism for a cutting device | US710186 | 1991-06-04 | US5129160A | 1992-07-14 | Don A. Bell |
| A chain saw feed mechanism includes an arm pivotally mounted to the chain saw and carrying a dog for pivotally engaging the workpiece at the kerf. Thrusting the chain saw along the longitudinal axis of the guide bar moves the guide bar along an arc concentric to the point of workpiece engagement and thereby cuts laterally through the workpiece. Longitudinal thrusting force applied by the operator transfers via the lever arm into lateral feed force needed for cutting the workpiece. The feed mechanism is particularly useful in aggregate cutting applications, where the chain saw is heavy and large cutting forces are needed to pass the saw through the aggregate. | ||||||
