Figure 1 is a side elevation of the improved device, partly broken away or in
section to better illustrate certain details of construction, and with one standard
removed.
Figure 2 is a rear elevation of the device, also partly in section.
Referring by letter to the drawings, A B represent standards, each preferably
having two legs provided with feet a a, that may be made fast to a floor or other
suppert, by screws, spikes or other suitable means. A rod C, passed through
opposing perforations in the two standards, aids in keeping the same in line with
each other.
Each standard is provided with a vertically disposed head-extension D that
constitutes one section of a socket for a ball E, at one end of a clamp jaw F, and
the socket-sections have their meeting-edges recessed, as shown at bb, to form seats
of sufficient depth, engagable with the neck c of said ball, when it is desirable to
hold said clamp-jaw in horizontal position in one direction or the other from the
vertical center of the supporting frame at a right angle to the latter. The meeting
edges of the standard extensions D are also recessed, as shown at d, to form a
circular track for the hall-neck c, and from the foregoing it will be seen that the
aforesaid clamp-jaw and parts in connection therewith may be adjusted to extend
horizontally or vertically from the frame, or at any angle intermediate of a
horizontal and vertical plane, while at the same time said jaw may have a pivotal
adjustment when the ball-neck c is out of its seats bb, and within the limits of its
circular track d.
The head extensions D D of the standards A B are provided, just beneath the
socketed parts that receive the ball E, with bored hubs, marked ef, respectively.
The hube of the standard A has a screw-threaded bore, and the hub f of the
standard B has a smooth bore. These bored hubs are for the reception of a
spindle G, which has a screw-threaded portion g which engages with the screw-
threaded bore of the hub e, and a collar h, rigid on the spindle, which comes against
the end of the bub f, and each end of the spindle is provided with hand wheels or

page_text: spokes ii for convenience in turning the spindle, whereby the socketed head-
extensions D D of the standards A B may be drawn closely together, when desired,
to firmly clamp the ball E, or by turning the spindle G in the opposite direction,
so that said parts D D may separate and loosen their grip upon said ball.
The clamp-jaw F is provided with a recessed or chambered portion j for the
reception of a hollow shank pertaining to another clamp-jaw H that faces the one
aforesaid, and contained within said recess and shank, under tension, is a spiral-
spring I that surrounds a shouldered screw-rod K, the latter being provided at its
outer end with a hand-wheel or spokes m to facilitate its adjustment. The screw-
portion of the rod K engages a screw-threaded opening in the ball-neck c and the
shouldered outer portion n of said rod bears against the clamp-jaw H to actuate
the latter against resistance of the aforesaid spring. To limit outward movement
of the clamp-jaw H, its shank k is provided with a longitudinal recess o engaged by
a stop-screw set in the wall of the recessed portion of the other jaw F.
The jaws FH being of metal, it is preferable to recess the same, as shown at q,r,
and provide them with bearing-blocks L L of rubber, wood, or other suitable
material that will not mar work held in the vice embodying said jaws. The blocks
herein shown are square and have their several faces provided with seats of
different radius in order that the vice may be best adapted to clamp tubing or
other round work of different diameters. A bails is connected to each block, and
being forced down on the curved outer corners of the corresponding jaw, it holds
said block in position for use. The blocks being detachable from the jaws, new
ones may be readily substituted for those that become worn or broken.
A structure such as the one described enables a filer or other workman to readily
shift whatever he is working on into convenient position without the loss of time
that results in the use of an ordinary hand or bench-vice.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is:
1. The combination of a frame comprising separate standards, head extensions
of the standards constituting a sectional socket, a vice having a ball-end adjustable
in the socket, and suitable means for uniting the separate standards and clamping
the socket-sections on said ball-end of the vice.
2. The combination of a frame comprising separate standards, head extensions
of the standards constituting a sectional socket having vertical seats, a vice having
a ball-end adjustable in the socket as well as a neck for the engagement of said
seats, and a screw-spindle for uniting the separate standards and clamping the
socket-sections on said ball-end of the vice.
3. The combination of a frame comprising separate standards, head extensions
of the standards constituting a sectional socket, a vice comprising two opposing
clamp-jaws held together by telescoping shanks, and actuated by a screw-rod
against the force of a tension spring, a ball at the end of one of the clamp-jaws
adjustable within the described sectional socket, adjustable non-metallic bearing
blocks insertible in the vice-jaws, and a screw-spindle for uniting the separate
standards and clamping the socket-sections on the described ball-eud of the vice.
