Abstract
Abstract A rasp handle has an elongate body portion with a pistol-type grip extending therefrom and rasp retaining structure at its front end. Such structure includes a fixed jaw and a slide jaw constructed and arranged for sliding movement relative to the fixed jaw between a forward closed locking position where a rasp is locked between the jaws and a rearward open rasp receiving and releasing position. A lever is connected to shift the slide jaw between its closed and open positions. A pivot interconnects the lever and the slide jaw so that the lever is free to move between a locked position adjacent the body portion and an unlocked jaw manipulating position away from the body portion.

Claim 1
Independent Claim
114 words
A rasp handle having an elongate body portion with a pistol-type grip extending therefrom and rasp retaining means at the front end thereof, the rasp retaining means including a fixed jaw, a slide jaw constructed and arranged for sliding movement relative to the fixed jaw between a forward closed locking position where a rasp is locked between the jaws and a rearward open rasp receiving and releasing position, a lever connected to shift the slide jaw between its closed and open positions, and pivot means interconnecting the lever and the slide jaw whereby the lever is free to move between a position adjacent the body portion and a position away from the body portion.
Claim 2
Dependent Claim
114 words
A rasp handle having an elongate body portion with a pistol-type grip extending therefrom and rasp retaining means at the front end thereof, the rasp retaining means including a fixed jaw, a slide jaw constructed and arranged for sliding movement relative to the fixed jaw between a forward closed locking position where a rasp is locked between the jaws and a rearward open rasp receiving and releasing position, a lever connected to shift the slide jaw between its closed and open positions, and pivot means interconnecting the lever and the slide jaw whereby the lever is free to move between a position adjacent the body portion and a position away from the body portion.
Claim 3
Dependent Claim
60 words
A rasp handle as in claim 1 wherein the lever has a rear end portion positioned adjacent the pistol-type grip when the slide jaw is in its forward closed position and the lever is positioned adjacent the body portion thereby prevent the jaws from sliding open except when the lever is pivoted to its position away from the body portion.
Claim 4
Dependent Claim
43 words
A rasp handle as in claim 2 wherein the rear end portion of the lever includes a rearwardly facing tongue and the pistol-type grip includes a groove constructed and arranged to receive the tongue when the lever is positioned adjacent the body portion.
Claim 5
Dependent Claim

A rasp handle as in claim 1 wherein the fixed jaw includes internal undercut means constructed and arranged for mating engagement with the rasp and the slide jaw includes an internal abutment surface adapted to hold the rasp in mating engagement with the undercut means when the slide jaw is in its forward closed position and the rasp is locked between the jaws.
Claim 6
Dependent Claim
54 words
A rasp handle as in claim 4 wherein the fixed and slide jaws each includes a semicylindrical recess that together form a cylindrical rasp receiving recess when the slide jaw is in its closed position, and an internal semiannular rib on the fixed jaw extending into the semicylindrical recess to provide the undercut means.
Claim 7
Dependent Claim
24 words
A rasp handle as in claim 5 wherein the cylindrical rasp receiving recess has a longitudinal axis disposed approximately 45° to the body portion.
Claim 8
Dependent Claim
