Abstract
Abstract A folding sawbuck is disclosed that combines a cross frame design with integral vertical members, allowing a large quantity of logs or other wood to be cut into firewood at one time. The use of independant support assemblies, secure by horizontal members, provides an obstruction free cutting path that gives fast and safe cuts under all types of conditions, with all types of wood. The sawbuck is designed to be folded compactly for storage, and then opened for use with a minimum of difficulty. Two different embodiments of the invention are disclosed, each design using a different means for forming the "X"-frame portion of the main support assemblies. The invention is designed as a kit, with all parts pre-cut for easy assembly, or it can be manufactured fully assembled. The sawbuck can be constructed from either wood, metal or plastics.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
248 words
A portable sawbuck comprising: (a) a plurality of support assemblies, each support assembly having a first cross member, a second cross member fixedly attached to the first crossmember by pivot means where they cross, one end of each of the crossmembers being formed to lie flat against the ground when in the upright, fully opened position; (b) each support assembly also having a first vertical support member attached to the first cross member by pivot means, and a second vertical support member attached to the second cross member by pivot means, both pivot means being located where the vertical support members connect to each cross member; (c) a first horizontal member being fixedly attached to the lower portion of each first cross member so as to connect the plurality of support assemblies together; (d) a second horizontal member being fixedly attached to the lower portions of the second cross members of the support assemblies substantially in the same manner as the first horizontal member, and for the same purpose as the first horizontal member; (e) support bracket means located so as to secure the lower end of each vertical member when the support assemblies are fully opened, in such a manner that the vertical members are plumb vertically when their lower ends are engaged in the support bracket means; (f) a third horizontal member, being fixedly attached to the upper end of each first cross member, connecting the plurality of support assemblies so as to provide additional strength.

Claim 8
Dependent Claim
294 words
A portable sawbuck comprising: (a) A plurality of support assemblies, each support assembly having a first crossmember, a bracket means pivotably attached to said first crossmember, a second cross member fixedly attached to said bracket means, a third crossmember also fixedly attached to the bracket means so that the second crossmember and the third crossmember lie parallel to each other on opposite sides of the first crossmember, thereby forming an "x" configuration when the sawbuck is placed in the open position, and also such that all the crossmembers in the support assembly occupy a common plane, and also such that the second and third crossmembers are offset from each other so that when the support assembly is closed, the second and third crossmembers lie parallel to the first crossmember, and when the support assembly is opened, the second and third crossmembers are generally perpendicular to the first crossmember; (b) Each support assembly also having a first vertical member pivotably attached to the first crossmember; (c) Each support assembly also having a second vertical member pivotably attached to the third crossmember; (d) a first horizontal support member fixedly attached to the lower portion of each support assembly's first crossmember; (e) a second horizontal support member fixedly attached to the lower portion of the second crossmember of each support assembly; (f) a third horizontal member, fixedly attached to the first crossmember of each support assembly, the third horizontal member being located at the top end of each support assembly's first crossmember; (g) support bracket means located so as to secure the lower end of each vertical member when the support assemblies are fully opened, in such a manner that the vertical members are plumb vertically when their lower ends are engaged in the support bracket means.
