Abstract
Abstract A device for releasably holding a nail or the like during a nail-driving operation has an elongated rigid shank with a forward extension adapted to releasably retain the nail in axial alignment with the shank. The forward extension is made of a resilient material having limited flexibility and has a selfclosing opening in the leading end thereof through which the head of the nail can be inserted to be retained in engagement with the leading end of the shank. The leading end of the shank has a concave face to retain desired alignment between the shank and the nail and a relatively small depression is provided in the concave face to receive small sized nail heads for maintenance of proper alignment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A holder for releasably retaining fasteners during driving operations comprising: a tool engaging portion with leading and trailing ends, and a fastener-head receiving member secured to the leading end of the tool engaging portion, said receiving member including a sleeve in surrounding relation to said tool engaging portion and a flexible membrane across the leading end of said sleeve and spaced from the leading end of the tool engaging portion to define a shallow receptacle therein, said flexible membrane provided with at least one slotted portion forming a selfclosing opening therethrough dimensioned for insertion of the head of a fastener into engagement with the leading end of the tool engaging portion, said slotted portion located centrally of said membrane and terminating short of the leading end of said sleeve, the resiliency of the receiving member being such as to grip the fastener and yieldingly maintain it in engagement with the leading end of the tool engaging portion.
Claim 2
Dependent Claim
157 words
A holder for releasably retaining fasteners during driving operations comprising: a tool engaging portion with leading and trailing ends, and a fastener-head receiving member secured to the leading end of the tool engaging portion, said receiving member including a sleeve in surrounding relation to said tool engaging portion and a flexible membrane across the leading end of said sleeve and spaced from the leading end of the tool engaging portion to define a shallow receptacle therein, said flexible membrane provided with at least one slotted portion forming a selfclosing opening therethrough dimensioned for insertion of the head of a fastener into engagement with the leading end of the tool engaging portion, said slotted portion located centrally of said membrane and terminating short of the leading end of said sleeve, the resiliency of the receiving member being such as to grip the fastener and yieldingly maintain it in engagement with the leading end of the tool engaging portion.
Claim 3
Dependent Claim
46 words
The holder of claim 1 wherein said membrane is convex and has intersecting slotted portions defining flexible flaps in said membrane to allow the head of a fastener to be inserted through the opening and into engagement with the leading end of the tool engaging portion.
Claim 4
Dependent Claim
25 words
The holder of claim 1 wherein the leading end of the tool engaging portion is concave defining a seat for the head of the fastener.
Claim 5
Dependent Claim
26 words
The holder of claim 3 wherein the concave leading end of the tool engaging portion has a centrally located indentation for receiving small sized fastener heads.
Claim 6
Dependent Claim
18 words
The holder of claim 1 wherein said sleeve tightly surrounds the leading end of the tool engaging portion.
Claim 7
Dependent Claim
15 words
The holder of claim 5 wherein said receiving member is made of a rubber-like material.
Claim 8
Dependent Claim
17 words
The holder of claim 6 wherein said tool engaging portion is made of a hardened steel material.
Claim 9
Dependent Claim
201 words
A holder for releasably retaining nails and the like during nail-driving operations comprising: an elongated cylindrical shank of hardened steel having a trailing end adapted to be contacted with a driving tool and a leading end adapted to seat the head of a nail, said leading end having a forwardly directed concave face with a centrally located indentation in the concave face, and a knurled intermediate portion to facilitate gripping of the holder, and an axial extension sleeve member of a rubber-like material bonded to and circumscribing the leading end of the shank, a resilient retainer portion extending across the leading end of said extension sleeve member axially spaced from the concave leading end of the shank and having intersecting slotted portions forming a self-closing opening in said retainer portion, said slotted portions terminating short of the leading end of said sleeve and defining adjacent circumferentially spaced resilient flap means of limited flexibility to allow the head of a nail to be inserted through the opening and into engagement with the leading end of the shank whereby the head is releasably retained by the resilient flaps in the axial space between the retainer portion and the leading end of said shank.
Claim 10
Dependent Claim
201 words
A holder for releasably retaining nails and the like during nail-driving operations comprising: an elongated cylindrical shank of hardened steel having a trailing end adapted to be contacted with a driving tool and a leading end adapted to seat the head of a nail, said leading end having a forwardly directed concave face with a centrally located indentation in the concave face, and a knurled intermediate portion to facilitate gripping of the holder, and an axial extension sleeve member of a rubber-like material bonded to and circumscribing the leading end of the shank, a resilient retainer portion extending across the leading end of said extension sleeve member axially spaced from the concave leading end of the shank and having intersecting slotted portions forming a self-closing opening in said retainer portion, said slotted portions terminating short of the leading end of said sleeve and defining adjacent circumferentially spaced resilient flap means of limited flexibility to allow the head of a nail to be inserted through the opening and into engagement with the leading end of the shank whereby the head is releasably retained by the resilient flaps in the axial space between the retainer portion and the leading end of said shank.
