Abstract
Abstract A handle attachment for power chain saws to extend the use of the basic chain saw structure for cutting underbrush, weeds and the like. The curved handle attachment is detachably pivotally fixed on the body of the power chain saw and positions the cutting bar in a horizontal position instead of the conventional vertical position when the chain saw is being operated in a normal manner to cut wood. The handle attachment is adjustable to accommodate users of different height and such adjustability includes a link bar pivotally connected at one end to the handle and pivotally connected at the other end to the conventional chain saw handle. The handle of the chain saw attachment is provided with an adjustable position hand grip and a throttle control assembly. The saw bar of the chain saw is provided with a guard which functions not only as a stand but also prevents the chain having the cutting teeth thereon from striking the ground and this also permits the user or operator to rest without releasing the handle and also permits the tool or chain saw to stand independently.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
210 words
A power chain saw including, in combination, a chain saw having a body, a handle projecting from one end thereof, and a cutting bar and cutting teeth projecting from the other end thereof, and said power chain saw body having an auxiliary handle supporting element fixed thereto and said element including a transverse member in a plane above and transversely positioned with respect to a projected plane of said cutting bar when said cutting bar is in horizontal position with respect to the ground, rigid members connected to opposite ends of said transverse member and depending therefrom and connected at their lower ends to the body of the saw thereby spacing the transverse member in a plane above the body of the power chain saw, and an upstanding auxiliary handle detachably fixed to said transverse member said auxiliary handle includes means mating with said transverse member and clampable thereto so that said means and upstanding auxiliary handle may be pivoted with respect to the transverse member for adjusting the angular relationship of said handle with respect to said transverse member, the auxiliary handle extending from said supporting element for controlling the operation of said power chain saw when said cutting bar is in horizontal position with respect to the ground.
Claim 2
Dependent Claim
210 words
A power chain saw including, in combination, a chain saw having a body, a handle projecting from one end thereof, and a cutting bar and cutting teeth projecting from the other end thereof, and said power chain saw body having an auxiliary handle supporting element fixed thereto and said element including a transverse member in a plane above and transversely positioned with respect to a projected plane of said cutting bar when said cutting bar is in horizontal position with respect to the ground, rigid members connected to opposite ends of said transverse member and depending therefrom and connected at their lower ends to the body of the saw thereby spacing the transverse member in a plane above the body of the power chain saw, and an upstanding auxiliary handle detachably fixed to said transverse member said auxiliary handle includes means mating with said transverse member and clampable thereto so that said means and upstanding auxiliary handle may be pivoted with respect to the transverse member for adjusting the angular relationship of said handle with respect to said transverse member, the auxiliary handle extending from said supporting element for controlling the operation of said power chain saw when said cutting bar is in horizontal position with respect to the ground.
Claim 3
Dependent Claim
198 words
A power chain saw including, in combination, a chain saw having a body, a handle projecting from one end thereof and a cutting bar and cutting teeth projecting from the other end thereof, said power chain saw body having an auxiliary handle supporting element fixed thereto and said element including a transverse member, said transverse member being in a plane above and transversely positioned with respect to a projected plane of said cutting bar when said cutting bar is in horizontal position with respect to the ground, an upstanding auxiliary handle detachably fixed to said transverse member of said auxiliary handle supporting element and pivoted with respect thereto and extending therefrom for controlling the operation of said power chain saw when said cutting bar is in horizontal position with respect to the ground and a guard and stand is provided for preventing the cutting teeth from engaging the ground when the power chain saw is being operated with the cutting bar thereof horizontal to the ground, said guard and stand including means detachably fixed at one end to the cutting bar and mounting on the other end thereof an ovate loop which is spaced from the cutting bar.
Claim 4
Dependent Claim
198 words
A power chain saw including, in combination, a chain saw having a body, a handle projecting from one end thereof and a cutting bar and cutting teeth projecting from the other end thereof, said power chain saw body having an auxiliary handle supporting element fixed thereto and said element including a transverse member, said transverse member being in a plane above and transversely positioned with respect to a projected plane of said cutting bar when said cutting bar is in horizontal position with respect to the ground, an upstanding auxiliary handle detachably fixed to said transverse member of said auxiliary handle supporting element and pivoted with respect thereto and extending therefrom for controlling the operation of said power chain saw when said cutting bar is in horizontal position with respect to the ground and a guard and stand is provided for preventing the cutting teeth from engaging the ground when the power chain saw is being operated with the cutting bar thereof horizontal to the ground, said guard and stand including means detachably fixed at one end to the cutting bar and mounting on the other end thereof an ovate loop which is spaced from the cutting bar.
Claim 5
Dependent Claim
40 words
A power chain saw in accordance with claim 2, wherein a portion of said ovate loop provides a relatively plane portion for contact with the ground and for providing a stable support upon which the power chain saw may rest.
