as indicated in the various figures of the ac-
companying drawings. Said table is pro-
vided with dovetailed ways for the reception
of a movable bed I, said bed being provided
5 with dovetailed sides 11 to engage said ways
in table H. At the rear end of said bed I are
lugs J for supporting a hand-lever 7c, which
has an extension m for securing one end of a
spiral spring n. The opposite end of said
ro spring is secured to a rod i2, extending from
the rear of said bed I. Hand-lever k is also
provided with serrations or teeth 1 for hold-
ing work securely upon the bed. Said lever
is provided with a pawl for engaging teeth or
15 serrations 10, formed upon a standard i, lo-
cated on the front end of the bed I. Said le-
ver k is elastic toward the handle end for the
purpose of yielding when holding work upon
the bed I. By this means any of the notches
20 can be entered by the pawl 16, thus insuring
a firm clamping device. Also secured to said
bed I is a stop i' for holding the work exactly
at right angles to the shear-blades in con-
junction with the hand-lever k previously re-
25 ferred to.
The movable shear-blade 12 is a right line
on its front portion, and as it extends toward
the heel 14 it is in the form of a flat arc. By
this arrangement of the blade and the angle
30 it is secured to the movable arm B. Less
power is required to shear metal than by the
ordinary shears in present use. The main
object of the movable arm B, with its exten-
sion b, is for compactness, so that the hand-
35 lever E can be close to the shears. By this
means a single person can operate the device,
using one hand for holding the work and the
other hand for operating the lever E. No
other system of levers could accomplish these
4o results as regards their compactness, as indi-
cated by the present invention.
When operating my improved shears, the
table is not employed for cutting hot iron, as
such work is not of sufficient importance to
45 require accurate shearing. The table is em-
ployed mainly for cold-rolled iron and for ac-
curate shearing.
The hinged table is so located on the frame
of the machine that it is not in the way of the
50 person operating the shears.
I claim-
1. In hand-lever shears consisting of a right-
'angled lever, the vertical portion or operat-
ing-arm being of greater length than the base
55 or short arm of said right-angled lever, an ad-
justable brace secured to the extreme free
ends of said right-angled lever, the short arm
of said right-angled lever being pivoted to a
support or frame, a shearing-blade secured atthe angle of said right-angled lever for en- 6o
gagement with a shear-blade secured to a
frame or support and contacting said shear-
blade on said right-angled lever, a draw-bar
secured to the long arm of said right-angled
lever, the oppositeemnd of said draw-bar be- 65
ing secured to an operating -lever which is
pivoted to the frame of the machine, in com-
bination with a lateral brace contacting the
long arm of said right-angled lever and a half-
staple engaging said lateral brace for the pur- 70
pose as shown and described.
2. In hand-lever shears consisting of a right-
angled lever, the vertical portion or operat-
ing-arm being of greater length than the base
or short arm of said right-angled lever, said 75
short arm being pivoted to a support or frame,
a shearing-blade secured at the angle of said
right - angled lever for engagement with a
shear-blade secured to the frame or support
forming part of said machine, in combination 8o
with lateral brace, consisting of a half-staple
secured to the vertical arm. of said right-an-
gled lever, a standard engaging said half-
staple at one end, the opposite end or base
being secured to the frame or support of the 85
machine for the purpose as shown and de-
scribed.
3. In hand-lever shears consisting of a right-
angled lever, the perpendicular or vertical
portion being of greater length than the base 90
or short arm of said right-angled lever, said
short arm being pivoted.to a frame or sup-
port, a shearing-blade secured at the angle of
said right-angled lever for engagement with
a shear-blade secured to the frame or support 95
forming part of the machine, and the means
for operating said right-angled lever, in com-
bination with a hinged table which is pro-
vided with a clamping device thereon, said
clamping device consisting of a serrated le- ioo
ver, and a serrated standard for securing said
serrated lever for the purpose as shown and
described.
4. In hand -levers, the combination of a
right-angled arm bearing a shear-blade, said 105
shear-blade in contact with a blade on the
frame supporting said right-angled arm, a
hinged table on said frame, said table pro-
vided with a bed and operating-lever for se-
curing work on said bed, for the purpose as i1o
shown.
In testimony whereof I affix my signature
in presence of two witnesses.
