Abstract
Abstract The invention provides an adjustable holder for strip steel blade, the holder being fixable in a wood chipping machine cutter head. The blade fits over pins in one of a pair of clamping jaws (or in a shim carried by one of said jaws) and this jaw is adjustable towards or away from the cutting edge of the blade so as to adjust this edge to project beyond the holder to a required amount. The jaws are then clamped on to the blade by screws. The blade may be double-edged and reversible.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A steel strip blade holder which is detachably locatable in a cutting head of a wood chipping machine, said holder comprising two clamping jaws, connecting elements for clamping said jaws together and a steel strip blade clamped and interchangeably retained between said jaws, said steel strip blade being detachably connected to a holding means in fixed relation thereto; and adjusting means acting on said holding means to displace said holding means and said strip blade relative to at least one of said jaws so as to set said steel strip blade with its effective cutting edge projecting a required distance from said one jaw at right angles to the longitudinal direction of said cutting edge.
Claim 2
Dependent Claim
115 words
A steel strip blade holder which is detachably locatable in a cutting head of a wood chipping machine, said holder comprising two clamping jaws, connecting elements for clamping said jaws together and a steel strip blade clamped and interchangeably retained between said jaws, said steel strip blade being detachably connected to a holding means in fixed relation thereto; and adjusting means acting on said holding means to displace said holding means and said strip blade relative to at least one of said jaws so as to set said steel strip blade with its effective cutting edge projecting a required distance from said one jaw at right angles to the longitudinal direction of said cutting edge.
Claim 3
Dependent Claim
22 words
A blade holder as recited in claim 1, wherein said adjusting means includes adjusting screws acting on the other of said jaws.
Claim 4
Dependent Claim
35 words
A blade holder as recited in claim 1, wherein said steel strip blade has locating holes spaced apart in the longitudinal direction of said blade; and projections on said holding means engaging in said holes.
Claim 5
Dependent Claim
38 words
A blade holder as recited in claim 1, wherein said holding means projects with clearance beyond the edge of said steel strip blade opposite said cutting edge, and there forms an abutment surface co-operating with said adjusting means.
Claim 6
Dependent Claim
23 words
A blade holder as recited in claim 1, wherein said adjusting means include a pivotal eccentric rotatably mounted on at least one jaw.
Claim 7
Dependent Claim
40 words
A blade holder as recited in claim 5, wherein the eccentric includes two coaxial pivot mounting pins engaging respective jaws, both pivot pins simultaneously forming a setting means fixing said two clamping jaws in their positions relative to each other.
Claim 8
Dependent Claim
24 words
A blade holder as recited in claim 1, wherein said holding means comprises a shim, said shim being movably positioned between said clamping jaws.
Claim 9
Dependent Claim
54 words
A blade holder as recited in claim 2, wherein said screws forming part of said adjusting means threadedly engage in said one jaw with their longitudinal direction parallel to the plane of said steel strip blade, and at right angles to the longitudinal direction of said blade, and a lock nut for each screw.
Claim 10
Dependent Claim
72 words
A blade holder as recited in claim 8, wherein the other clamping jaw comprises said holding means and is provided with blade fixing pins and in its longitudinal region remote from the blade edge in use, is provided with an abutment surface for said adjusting means and with interchangeable spacers adjusting the spacing between said two clamping jaws in said remote region to that of the thickness of said steel strip blade.
Claim 11
Dependent Claim
29 words
A blade holder as recited in claim 9, wherein at least one clamping jaw is provided with positive locating means for locating said blade holder in a cutting head.
