Abstract

Abstract The tool holder is of a pencil type and includes a barrel or outer member in which is slidably carried a support or inner member that is connected in an end to end relation with a tool member for movement of the tool member to extended and retracted positions relative to one end of the barrel member. A linearly extendible and retractible latch means positioned transversely of and through the tool holder coacts with portions of the barrel member and the support member to define the retracted and extended positions of the tool member.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 235 words
A retractible tool holder comprising: a. a tubular barrel member, b. an elongated tubular tool support member, c. a tool member connectible to the front end of said support member, d. said support member and said tool member located within said barrel mEmber for slidable movement relative thereto between an inoperative position wherein said tool member is retracted inwardly from one end of said barrel member and an operative position wherein said tool member extends outwardly from a corresponding adjacent end of said barrel member, e. said support member having a pair of transversely opposite elongated longitudinally extended slots, and said barrel member having a pair of diametrically opposite openings in transverse alignment with said slots, one of said slots having an enlarged end portion of a size and shape corresponding to an adjacent one of said openings, and f. a retractible and extendible linear transverse latch means projected through said pair of openings and said pair of slots, including a locking member having an enlarged section movable within said one opening and the enlarged end portion of said one slot when said tool member is moved to the operative position thereof, whereby to lock said barrel member and support member against relative movement, said tool member, on movement of the enlarged section of said locking member out of said one opening and adjacent one of said slots, being movable to the inoperative position therefor.
Claim 2
Dependent Claim 235 words
A retractible tool holder comprising: a. a tubular barrel member, b. an elongated tubular tool support member, c. a tool member connectible to the front end of said support member, d. said support member and said tool member located within said barrel mEmber for slidable movement relative thereto between an inoperative position wherein said tool member is retracted inwardly from one end of said barrel member and an operative position wherein said tool member extends outwardly from a corresponding adjacent end of said barrel member, e. said support member having a pair of transversely opposite elongated longitudinally extended slots, and said barrel member having a pair of diametrically opposite openings in transverse alignment with said slots, one of said slots having an enlarged end portion of a size and shape corresponding to an adjacent one of said openings, and f. a retractible and extendible linear transverse latch means projected through said pair of openings and said pair of slots, including a locking member having an enlarged section movable within said one opening and the enlarged end portion of said one slot when said tool member is moved to the operative position thereof, whereby to lock said barrel member and support member against relative movement, said tool member, on movement of the enlarged section of said locking member out of said one opening and adjacent one of said slots, being movable to the inoperative position therefor.
Claim 3
Dependent Claim 46 words
The retractible tool holder according to claim 1 including: a. spring means in said barrel member mounted about said tool with the respective ends thereof in bearing engagement with said barrel member and support member to continuously urge said tool member to the inoperative position therefor.
Claim 4
Dependent Claim 53 words
The retractible tool holder according to claim 1 wherein: a. said latch means, on removal of said enlarged section of the locking member from said one opening and enlarged portion of said one slot, being engageable with the opposite end of said one slot to define the retracted position of said tool member.
Claim 5
Dependent Claim 56 words
A retractible tool holder according to claim 1 wherein: a. said support member and said tool member are in an axially aligned relation longitudinally of said barrel, and b. means releasably connecting together the adjacent ends of said tool member and support member including means for adjustably extending said tool member longitudinally of said support member,
Claim 6
Dependent Claim 58 words
A retractible tool holder according to claim 1 wherein: a. said support member and said tool member are in an axially aligned relation longitudinally of said barrel member, and b. means releasably connecting together the adjacent ends of said tool member and support member including means for locking said tool member against rotation relative to said support member.
Claim 7
Dependent Claim 121 words
The retractible tool holder according to claim 1 wherein: a. said locking member is of a tubular shape having an outer end section of a reduced size relative to said enlarged section, b. a guide member for said locking member having a first section located within the other one of said slots and the other one of said openings, and a second section slidably supported within said locking member, c. means within said locking member for continuously biasing said locking member in a direction toward and axially of said one opening, and d. stop means secured to the outer surface of said barrel and engageable with said enlarged section to limit the movement of said locking member by said biasing means.
Claim 8
Dependent Claim 80 words
A retractible tool holder according to claim 6 including: a. means for securing said stop means to said barrel member having an abutment portion projected inwardly of said barrel member and through said one slot, b. said abutment portion, on movement of the enlarged section of said locking member out of said one opening and enlarged portion of said one slot, being engageable with the opposite end of said one slot to define the retracted position of said tool member.
