Abstract
Abstract A vise for holding cap screws and the like, which grips the screw head by applying pressure between the underside of the head and the driving slot; the double-bit tool disks provided fit within the handle for storage, and the cover disks, which adjustably engage the screw head with the bit under pressure of a screw-cap, store at the rear of the handle under retention by a spare screw-cap; the handle has adaptation for mounting a drill chuck in place of the screw gripping mechanism.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A vise for holding elongate-shank headed objects, comprising: an elongate housing having forward and rearward ends, the forward end having an axial opening with coaxial larger and smaller diameters, a shoulder between said larger and smaller diameters, a member protrusive inwardly into the larger diameter proximate the shoulder, a tool disk having a periphery proportioned for sliding fit with said larger diameter, with a notch therein for receiving the inwardly protrusive member; a tool bit axially protrusive from the tool disk; a cover disk having a central aperture proportioned for freely receiving a shank of a said headed elongate-shank object with the head thereof against a face of said cover disk, said forward end of the housing having a thread thereon, and a cylindrical cap having an end with a central aperture therein smaller than said cover disk and an internal thread positioned for engaging the thread on the housing forward end, said cover disk being located within said cap.
Claim 2
Dependent Claim
160 words
A vise for holding elongate-shank headed objects, comprising: an elongate housing having forward and rearward ends, the forward end having an axial opening with coaxial larger and smaller diameters, a shoulder between said larger and smaller diameters, a member protrusive inwardly into the larger diameter proximate the shoulder, a tool disk having a periphery proportioned for sliding fit with said larger diameter, with a notch therein for receiving the inwardly protrusive member; a tool bit axially protrusive from the tool disk; a cover disk having a central aperture proportioned for freely receiving a shank of a said headed elongate-shank object with the head thereof against a face of said cover disk, said forward end of the housing having a thread thereon, and a cylindrical cap having an end with a central aperture therein smaller than said cover disk and an internal thread positioned for engaging the thread on the housing forward end, said cover disk being located within said cap.
Claim 3
Dependent Claim
72 words
A vise for holding elongate-shank heaDed objects as recited in claim 1, wherein the tool bit extends from said tool disk substantially to said forward end of the housing with the tool disk in operating position against said shoulder, wherein the cover disk is larger than said larger diameter, and wherein said cap and all said threads are proportioned for drawing the cover disk substantially against the front end of the housing.
Claim 4
Dependent Claim
40 words
A vise for holding elongate-shank headed objects as recited in claim 2, wherein the interior of the cap has a bore providing a clearance around the periphery of the cover disk when the cover disk is retained by the cap.
Claim 5
Dependent Claim
44 words
A vise for holding elongate-shank headed objects as recited in claim 3, wherein the tool bit comprises an elongate member passing through the tool disk and having first and second tool bits ends thereon, with the second tool bit end within said smaller diameter.
Claim 6
Dependent Claim
75 words
A vise for holding elongate-shank headed objects as recited in claim 4, wherein the inwardly protrusive member comprises a cylindrical pin, wherein the rearward end of the cylindrical pin is retained in a hole in said flange, and wherein a forwardly extending portion of the contour of said hole stabilizes the length of said pin and provides a visual and tactile indicator at the forward end of said housing for orienting said tool disk notch.
Claim 7
Dependent Claim
113 words
A vise for holding elongate-shank headed objects as recited in claim 5, wherein the rearward end of the housing has an axial opening therein having a diameter equal to said larger diameter, said axial opening accommodating a plurality of tool disks with differing tool bits, fitted within said axial opening; wherein the rearward end of the housing has a thread thereon like said thread on the forward end of the housing, a second cylindrical cap like the first said cylindrical cap, and a plurality of said cover disks retained at the rearward end of the housing by the second said cap, said plurality of cover disks having respective apertures of differing sizes therein.
Claim 8
Dependent Claim
39 words
A vise for holding elongate-shank headed objects as recited in claim 6, wherein the smaller diameter has threads therein for receiving a drill chuck, and wherein the housing has a handle portion with a plurality of wrenching flats thereon.
