Total Claims: 11
Claim 1
Independent Claim
162 words
In a chain saw sharpener, a frame comprising a web and spaced, parallel side walls extending therefrom to free edges, a carriage supported from one of said walls, outwardly thereof, for guided adjustment longitudinally thereof, means providing a longitudinal guideway inwardly of said one wall, threaded means supported by the other of said walls for movement toward and away from said one wall, two clamp screws, respectively penetrating said other wall at points near opposite ends thereof and more remote from said web than is said threaded means, said walls being interrupted intermediate their ends in a region near said web, said carriage being formed with two guide bores of equal diameter and equiangularly inclined toward each other to open through the inner face of said carriage into the region of interruption of said walls, and with a third bore of equal diameter opening perpendicularly through said face into said region, and means for accurately adjusting said carriage longitudinally of said frame.
Claim 2
Dependent Claim
162 words
In a chain saw sharpener, a frame comprising a web and spaced, parallel side walls extending therefrom to free edges, a carriage supported from one of said walls, outwardly thereof, for guided adjustment longitudinally thereof, means providing a longitudinal guideway inwardly of said one wall, threaded means supported by the other of said walls for movement toward and away from said one wall, two clamp screws, respectively penetrating said other wall at points near opposite ends thereof and more remote from said web than is said threaded means, said walls being interrupted intermediate their ends in a region near said web, said carriage being formed with two guide bores of equal diameter and equiangularly inclined toward each other to open through the inner face of said carriage into the region of interruption of said walls, and with a third bore of equal diameter opening perpendicularly through said face into said region, and means for accurately adjusting said carriage longitudinally of said frame.
Claim 3
Dependent Claim
52 words
The device of claim 1 in which the axes of said two guide bores lie in a common plane substantially perpendicular to said side walls and the axis of said third bore lies in a plane parallel to said common plane and between said common plane and the level of said web.
Claim 4
Dependent Claim
58 words
The device of claim 1 in which said means providing a longitudinal guideway is an anvil plate seated on the inner surface of said one wall at a level more remote from said web than said bores and formed adjacent its edge nearer said web with an open-ended, longitudinal groove facing said threaded means to define said guideway.
Claim 5
Dependent Claim
37 words
The device of claim 3 in which said anvil plate is removable for reversal and is formed, adjacent its opposite edge, with a second, open-ended, longitudinal groove, whose width is different from that of said first-named groove.
Claim 6
Dependent Claim
28 words
The device of claim 4 in which said carriage is mounted for movement transversely of the length of said side walls and substantially perpendicularly relative to said web.
Claim 7
Dependent Claim
20 words
The device of claim 5 including threaded means for so moving said carriage and locking the same in selected position.
Claim 8
Dependent Claim
29 words
The device of claim 1 including stop means between said walls and projecting into said region of interruption to present an abutment surface toward one end of said frame.
Claim 9
Dependent Claim
19 words
The device of claim 7 in which said stop means is resiliently flexible toward the level of said web.
Claim 10
Dependent Claim
25 words
The device of claim 7 in which said stop means is supported from said frame for bodily adjustment toward and away from said one end.
Claim 11
Dependent Claim
25 words
The device of claim 8 in which said stop means is supported from said frame for bodily adjustment toward and away from said one end.
