Abstract
Abstract This invention relates in general to a measuring device for portable chain saws, and more particularly to a measuring device which is attachable to any portable power saw, for measuring the logs or other materials being cut, so that the cut section will be of a predetermined uniformed length. This invention is characterized by the fact that the measuring element originates immediately below the cutting chain, and can be pivoted to the left or right of the blade, or retracted into storage in the same plane as the blade or chain.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
107 words
A measuring device for use with chain saws and adapted to cooperate with one or more threaded chain bar mounting studs on the chain saw housing, comprising; at least one elongated adaptor element having a threaded aperture on one end dimensioned to cooperate with a threaded chain bar mounting stud, a mounting bracket, comprising an apertured L-shaped bracket member operatively connected to said at least one adapter element, and a measuring apparatus rotatably mounted on said L-shaped bracket member, and adapted to be shifted along a portion of said bracket, to position its axis of rotation in the same plane as the blade on the chain saw.
Claim 2
Dependent Claim
107 words
A measuring device for use with chain saws and adapted to cooperate with one or more threaded chain bar mounting studs on the chain saw housing, comprising; at least one elongated adaptor element having a threaded aperture on one end dimensioned to cooperate with a threaded chain bar mounting stud, a mounting bracket, comprising an apertured L-shaped bracket member operatively connected to said at least one adapter element, and a measuring apparatus rotatably mounted on said L-shaped bracket member, and adapted to be shifted along a portion of said bracket, to position its axis of rotation in the same plane as the blade on the chain saw.
Claim 3
Dependent Claim
41 words
A measuring device as in claim 1; wherein, the elongated adaptor element further comprises a reduced diameter threaded stud portion on the other end, which cooperates with a washer and nut to secure the L-shaped bracket member to the adaptor element.
Claim 4
Dependent Claim
41 words
A measuring device as in claim 1; wherein, the threaded aperture extends the entire length of the elongated adaptor element, and cooperates with a threaded locking stud having an enlarged head to secure the L-shaped bracket member to the adaptor element.
Claim 5
Dependent Claim
22 words
A measuring device as in claim 1; wherein, the L-shaped bracket has an elongated aperture disposed in its vertical and horizontal legs.
Claim 6
Dependent Claim
42 words
A measuring device as in claim 4; wherein, the aperture in the vertical leg of the L-shaped bracket is dimensioned to receive a portion of the elongated adapter element and permit vertical displacement of the bracket with respect to the adaptor element.
Claim 7
Dependent Claim
23 words
A measuring device as in claim 4; wherein, the measuring apparatus comprises a rotatable housing which contains a flexible, retractable, elongated measuring member.
Claim 8
Dependent Claim
37 words
A measuring device as in claim 6; wherein, the measuring member is further provided with a T-shaped lug on its distal end, and releasable locking means which will maintain the member in its extended position during use.
Claim 9
Dependent Claim
27 words
A measuring device as in claim 7; wherein, the measuring apparatus is operatively connected to a base member which is releasably secured to the L-shaped bracket member.
Claim 10
Dependent Claim
38 words
A measuring device as in claim 8; wherein, the base member is provided with a plurality or recesses which act as detents to prevent the rotation of the measuring member housing with respect to the L-shaped bracket member.
Claim 11
Dependent Claim
39 words
A measuring device as in claim 9; wherein, the measuring apparatus is attached to the L-shaped bracket by an elongated spring biased rod member, which is dimensioned to be received within an elongated aperture in the L-shaped bracket member.
Claim 12
Dependent Claim
30 words
A measuring device as in claim 10; wherein, the rod member extends through an aperture in the base member and is secured on one end to the measuring member housing.
Claim 13
Dependent Claim
40 words
A measuring device as in claim 11, wherein, the rod member is surrounded by a helical spring having one end which bears on an enlarged head on said rod member and the other end bears on the L-shaped bracket member.
Claim 14
Dependent Claim
46 words
A measuring device as in claim 1; wherein, the mounting bracket further comprises an apertured rectangular bracket member, which is dimensioned to receive a portion of said elongated adaptor element, and said rectangular bracket member is disposed between the L-shaped bracket member and said adaptor element.
