Abstract
Abstract An improved scraping tool has a pivoting scraping blade. The top of the blade holder has an axis parallel to the blade edge and it is pivotally attached under a support arm which is an angled extension of a grasping handle. The blade holder swivels freely within pre-determined limits on the angled handle extension to obtain an optimum working angle. The pivoting blade permits the handle to be angled away from the working surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A scraping tool comprising: an elongate handle having an axially mounted connecting rod extending from one end; a support arm coupled to said connecting rod at an angle, which forms an angled extension of said handle; a pivotable holding member for holding a blade having a scraping edge; a scraping blade mounted in the holding member having a scraping edge which is pivotable with said holding member to a position in which the scraping edge is aligned parallel to said support arm; dowel means forming a pivotal connection between said support arm and said holding member about a pivot axis so that said scraping edge may be aligned with said support arm and may be swiveled about said pivotal connection to be angled with respect to said support arm; and means for limiting the pivotal movement of said holding member relative to said support arm.
Claim 2
Dependent Claim
145 words
A scraping tool comprising: an elongate handle having an axially mounted connecting rod extending from one end; a support arm coupled to said connecting rod at an angle, which forms an angled extension of said handle; a pivotable holding member for holding a blade having a scraping edge; a scraping blade mounted in the holding member having a scraping edge which is pivotable with said holding member to a position in which the scraping edge is aligned parallel to said support arm; dowel means forming a pivotal connection between said support arm and said holding member about a pivot axis so that said scraping edge may be aligned with said support arm and may be swiveled about said pivotal connection to be angled with respect to said support arm; and means for limiting the pivotal movement of said holding member relative to said support arm.
Claim 3
Dependent Claim
72 words
The device of claim 1, wherein said pivotable movement limiting means comprises a stopping pin coupled to said support arm, which projects below said support arm into a groove under the pin in the upper portion of the holding member wherein said stopping pin projects below the edges of the groove and permits the holding member to pivot freely until one of the grooved edges comes into contact with the stopping pin.
Claim 4
Dependent Claim
69 words
The device of claim 2, wherein said holding member comprises: an upper portion pivotally coupled below said support arm, by a dowel; a lower portion comprising first and second grasping plates having upper and lower edges; and means for coupling the upper edges of said grasping plates to said upper portion, wherein the lower grasping plate edges make contact under tension, and further wherein a space is defined therebetween.
Claim 5
Dependent Claim
32 words
The device of claim 3, further comprising a bolt threadably engaged with said first grasping plate, wherein rotation of said bolt causes it to project into the space between said grasping plates.
Claim 6
Dependent Claim
21 words
The device of claim 4, wherein said handle has at least one thumb groove on the end nearest said support arm.
