Abstract
Abstract A wood slashing machine specifically intended for use with a conventional loading machine has a trailable vehicle formed by a frame and a pair of wheels mounted on the frame. Portions of the frame form a bed for restricting the movement of pulpwood, saw logs, fence posts, and the like, arranged on the bed by the loading machine. A circular saw is mounted on the frame as by a four-link mechanism actuated from the loading machine for cutting of articles arranged on the bed. The length of the articles cut off may be gauged by a stop plate adjustably mounted on the slashing machine frame. The bed is advantageously arranged so that the article being cut is spaced furthest from the frame at a point adjacent the saw so as to place the area being cut in tension and facilitate sawing.

Claim 2
Dependent Claim
236 words
A slashing machine, comprising, in combination: a. a frame; b. means mouNted on the frame for making same mobile; c. mean on the frame for retaining articles; d. means mounted on the frame for cutting articles retained by the retaining means, the cutting means including a saw, and means for movably mounting the saw on the frame, the saw mounting means including a four-link mechanism constructed from links having a pair of spaced ends, a first link of these links being pivotally mounted at a one end on the frame, a second link pivotally mounted at a one end to the other end of the first link and connected to the saw at the other end, a third link pivotally mounted at a one end to the frame, the first and third links being pivotally mounted on the frame at a common point, and a fourth link pivotally connected at a point arranged between the ends of the second link and to the third link; and e. means mounted on the frame for gauging a length of material to be cut off, the length gauging means including a stop member pivotally mounted on the frame transversely with respect to the length of an article to be cut, and arranged for selectively swinging into a position permitting longer than usual lengths of wood to be cut off, the structure further including means for swinging the stop member.
Claim 3
Dependent Claim
216 words
A slashing machine, comprising, in combination: a. a frame; b. means mounted on the frame for making same mobile; c. means on the frame for retaining articles; and d. means mounted on the frame for cutting articles retained by the retaining means, the cutting means including a saw, and means for movably mounting the saw on the frame, the saw mounting means including a four-link mechanism constructed from links each having a pair of spaced ends, a first link of these links being pivotally mounted at a one end of the frame, a second link pivotally mounted at a one end to the other end of the first link and connected to the saw at the other end, a third link pivotally mounted at a one end to the frame, the first and third links being pivotally mounted on the frame at a common point, and a fourth link pivotally connected to a point arranged between the ends of the second link and to the third link, the third link being a control arm biasedly attached to the frame and arranged for the four-link mechanism to overcome the bias on the third link and pivot about the common point away from an article being cut when the saw is forced into material beyond the capacity thereof.
