Abstract
Abstract Disclosed herein is a work holder for supporting a workpiece, the work holder including a frame and an upright member supported by the frame and having a longitudinal axis. The work holder also includes a support member for supporting the workpiece, and a bracket member supporting the support member and supported by the upright member for movement longitudinally on the upright member. The support member is also supported for pivotal movement about a generally horizontal axis and about an axis transverse to both the generally horizontal axis and the upright member.

Claim 1
Independent Claim
192 words
A work holder for supporting a workpiece, the work holder including a frame, an upright member supported by said frame and having a longitudinal axis, a support member for supporting the workpiece, means for supporting the support member for movement along said longitudinal axis including a bracket member supported by said upright member and movable longitudinally on said upright, for pivotal movement about a generally horizontal axis, and for tilting movement about an axis transverse to said generally horizontal axis and transverse to said upright member, an upwardly and outwardly extending arm supported by said bracket member, a second arm supported by said upwardly and outwardly extending arm, said second arm having a free end supporting a suction member, said suction member being engageable with said workpiece for support thereof, a pair of collars, each of said collars having a longitudinal axis, said collars being joined together in side-by-side relation and with the longitudinal axes of said collars being angularly disposed, one of said collars being adjustably supported longitudinally and circumferentially on said upwardly and outwardly extending arm, and the other of said collars supporting said second arm for adjustable positioning thereof.
Claim 2
Dependent Claim
192 words
A work holder for supporting a workpiece, the work holder including a frame, an upright member supported by said frame and having a longitudinal axis, a support member for supporting the workpiece, means for supporting the support member for movement along said longitudinal axis including a bracket member supported by said upright member and movable longitudinally on said upright, for pivotal movement about a generally horizontal axis, and for tilting movement about an axis transverse to said generally horizontal axis and transverse to said upright member, an upwardly and outwardly extending arm supported by said bracket member, a second arm supported by said upwardly and outwardly extending arm, said second arm having a free end supporting a suction member, said suction member being engageable with said workpiece for support thereof, a pair of collars, each of said collars having a longitudinal axis, said collars being joined together in side-by-side relation and with the longitudinal axes of said collars being angularly disposed, one of said collars being adjustably supported longitudinally and circumferentially on said upwardly and outwardly extending arm, and the other of said collars supporting said second arm for adjustable positioning thereof.
Claim 3
Dependent Claim
158 words
A work holder for supporting a workpiece, said work holding including a frame, an upright member supported by said frame and having a longitudinal axis, a bracket, means adjustably supporting said bracket on said upright member for movement longitudinally of said upright member, a first mounting member, a supporting element adapted to engage and support the workpiece, means for adjustably fixing said support element to said first mounting member to variably locate said support element relative to said first mounting member, means adjustably supporting said first mounting member on said bracket for movement about a first axis, a second mounting member, a support member adapted to engage and support the workpiece, means adjustably fixing said support member to said second mounting member to variably locate said support member relative to said second mounting member, and means adjustably supporting said second mounting member on said first mounting member for movement about a second axis perpendicular to said first axis.
Claim 4
Dependent Claim
158 words
A work holder for supporting a workpiece, said work holding including a frame, an upright member supported by said frame and having a longitudinal axis, a bracket, means adjustably supporting said bracket on said upright member for movement longitudinally of said upright member, a first mounting member, a supporting element adapted to engage and support the workpiece, means for adjustably fixing said support element to said first mounting member to variably locate said support element relative to said first mounting member, means adjustably supporting said first mounting member on said bracket for movement about a first axis, a second mounting member, a support member adapted to engage and support the workpiece, means adjustably fixing said support member to said second mounting member to variably locate said support member relative to said second mounting member, and means adjustably supporting said second mounting member on said first mounting member for movement about a second axis perpendicular to said first axis.
Claim 5
Dependent Claim
49 words
A work holder in accordance with claim 2 and further including a second support element adapted to engage and support the workpiece, and means for adjustably fixing said second support element to said first mounting member to variably locate said second support element relative to said first mounting member.
Claim 6
Dependent Claim
25 words
A work holder in accordance with claim 2 wherein said support element includes an outer end having thereon a suction member engageable with the workpiece.
Claim 7
Dependent Claim
64 words
A work holder in accordance with claim 2 wherein said support element comprises a first arm extending upwardly from said first mounting member, a second arm extending from said first arm and having an outer end with a suction member, and means for connecting said first and second arms for adjustment therebetween to variably locate said suction member relative to said first mounting member.
Claim 8
Dependent Claim
68 words
A work holder as set forth in claim 2 wherein said means for supporting said bracket for movement longitudinally of said upright member includes a rotatable screw supported by said upright member in generally parallel relation to said upright member, and means for threadably coupling said bracket to said screw for causing movement of said bracket longitudinally on said upright member in response to rotation of said screw.
Claim 9
Dependent Claim
66 words
A work holder as set forth in claim 6 wherein said upright member comprises an elongated hollow structure and wherein said screw is supported therein, and wherein said coupling means includes a member having a threaded bore threadably housing said screw and connected to said bracket whereby said coupling means member and said bracket are movable longitudinally on said upright member when said screw is rotated.
Claim 10
Dependent Claim
90 words
A work holder as set forth in claim 2 wherein said means for adjustably supporting said second mounting member on said first mounting member includes a bore in one of said mounting members, and a pivot member extending from the other of said mounting members and positioned in said bore, and further including means for limiting the relative movement of said first and second mounting members including an arcuate slot in one of said mounting members and a member extending from the other of said mounting members into said slot.
Claim 11
Dependent Claim
30 words
A work holder as set forth in claim 2 wherein said means for supporting said first mounting member for movement includes a generally horizontal pivot pin supported by said bracket.
Claim 12
Dependent Claim
62 words
A work holder as set forth in claim 9 and further includes means for pivoting said first mounting member about said pivot pin, said pivoting means including a threaded bore in said bracket, and a screw supported in said threaded bore and including an end engageable against said first mounting member for pivoting said first mounting member upon rotation of said screw.
Claim 13
Dependent Claim
61 words
