Abstract
Abstract A holding arrangement for a motor operated chain saw which includes a handle near the front end of the motor housing and a support for engaging the lower arm near the rear end of the motor housing. The support may be ring-like or yoke-like and the support and handle are carried by a member which is connected to the motor housing by resilient vibration damping elements.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
159 words
An arrangement for holding saws, especially motor driven chain saws having a motor housing and a saw rail projecting from one end of the housing; at least one hand graspable handle connected to the housing near the rail end thereof, and arcuate support means connected to the housing in spaced relation to said handle and adapted for supporting engagement with the lower arm simultaneously during grasping of said handle, said arcuate support means at least in part surrounding the lower arm kept from passing entirely therethrough to assure both hand and arm support during saw operation both below and above arm level work positioning thereof, said support means defining a passage only for receiving the arm therein and being spaced from said handle, the axis of said passage extending in the direction of the length of said rail and being substantially in the plane of said handle, said support means being in the form of a substantially rigid ring.
Claim 2
Dependent Claim
159 words
An arrangement for holding saws, especially motor driven chain saws having a motor housing and a saw rail projecting from one end of the housing; at least one hand graspable handle connected to the housing near the rail end thereof, and arcuate support means connected to the housing in spaced relation to said handle and adapted for supporting engagement with the lower arm simultaneously during grasping of said handle, said arcuate support means at least in part surrounding the lower arm kept from passing entirely therethrough to assure both hand and arm support during saw operation both below and above arm level work positioning thereof, said support means defining a passage only for receiving the arm therein and being spaced from said handle, the axis of said passage extending in the direction of the length of said rail and being substantially in the plane of said handle, said support means being in the form of a substantially rigid ring.
Claim 3
Dependent Claim
23 words
An arrangement according to claim 1, in which the central axis of said handle extends near the center of gravity of said motor.
Claim 4
Dependent Claim
43 words
An arrangement according to claim 1, in which the ring has a downwardly facing inside surface adapted to engage the top of the lower arm, said surface being substantially elliptical with the greater width extending transversely to the plane of the said rail.
Claim 5
Dependent Claim
54 words
An arrangement according to claim 1, in which the central axis of said handle is substantially parallel to the plane of said rail and substantially at right angles to the longitudinal direction of said housing, said central axis of said handle being near the axis of said ring and substantially at right angles thereto.
Claim 6
Dependent Claim
35 words
An arrangement according to claim 2, in which said surface on the inside of the ring is oval in cross sectional slope with the greater dimension thereof substantially parallel to the axis of said ring.
Claim 7
Dependent Claim
19 words
An arrangement according to claim 2, in which said surface on the inside of the ring is hose shaped.
Claim 8
Dependent Claim
64 words
An arrangement according to claim 1, in which said ring is supported on said housing for pivotal movement thereon in the fore and aft direction about a first axis substantially at right angles to the plane of said rail and for rotary movement about a second axis parallel to the plane of said rail, said first and second axes intersecting at a right angle.
Claim 9
Dependent Claim
40 words
An arrangement according to claim 1, in which said handle and support means are on top of said housing with said handle near the rail end of said housing and said support means near the other end of said housing.
Claim 10
Dependent Claim
25 words
An arrangement according to claim 8, which includes vibration damping means interposed between at least one of said handle and support means and said housing.
Claim 11
Dependent Claim
84 words
An arrangement according to claim 9, which includes a rigid member to which said handle and support means are fixed, and resilient vibration damping means connecting said rigid member to said housing, saiD vibration damping means comprising a pair of laterally spaced damping elements near the rail end of said member and a single damping element near the opposite end of said member and near the central plane of said housing, said damping elements being disposed at the vertices of an acute angle triangle.
Claim 12
Dependent Claim
19 words
An arrangement according to claim 10, in which said single damping element is substantially directly beneath said support means.
Claim 13
Dependent Claim
40 words
An arrangement according to claim 10, in which said pair of damping elements are disposed on the opposite side of said handle from said rail end of said housing and one thereof is substantially in the plane of said rail.
Claim 14
Dependent Claim
26 words
An arrangement according to claim 10, in which the principal direction of freedom of said damping elements is substantially parallel to the plane of said rail.
Claim 15
Dependent Claim
40 words
An arrangement according to claim 10, in which each damping element comprises a pair of elastic sleeves in coaxial relation on an axis perpendicular to the plane of said rail, and a mandrel common to each said pair of sleeves.
Claim 16
Dependent Claim
46 words
An arrangement according to claim 14, in which said rigid member is concave toward said housing so as to serve as a cap for the housing, said damping elements being disposed in the space between the bottom of said member and the top of said housing.
