ROBERT MONDAY, OF LAMPASAS, ASSIGNOR OF ONE-HALF TO JOSEPH P.
DEVINE, OF SAN ANTONIO, TEXAS.
ANIMAL-SH EARS.
SPECIFICATION forming part of Letters Patent No. 485,044, dated August 26, 1890.
Application filed May 2, 1890. Serial No, 350,365. (No model,)fo all whom it nmay concern:
Be it known that I, ROBERTI MONDAY, a citi-
zen of the United States, residing at Lam-
pasas, in the county of Lampasas and State of
5.Texas, have invented new and useful Ani-
mal-Shears, of which the following is a speci-
fication.
The invention relates to improvements in
animal-shears.
to The object of the present invention is to
simplify and improve the construction of
animal-shears, and render their operation
more positive and reliable.
The invention consists in the construction,
15 novel combination, and arrangement of parts
hereinafter fully described, illustrated in the
accompanying drawings, and pointed out in
the claims hereto appended.
In the drawings, Figure 1 is a perspective
20 view of a pair of animal-shears constructed
in accordance with this invention. Fig. 2 is
a reverse plan view. Fig. 3 is a central ver-
tical longitudinal sectional view. Fig. 4 is a
sectional view on the line x x of Fig. 3. Fig.
25 5 is a similar view on line y y of Fig. 3.
Referring to the accompanying drawings,
1 designates a base-plate constructed of sheet-
steel, and provided with a series of station-
ary cutting-knives 2, that have their right-
30 hand edges sharpened and adapted to co-op-
erate with the similarly-constructed left-hand
edge 3 of pivoted knives or blades 4, and the
operation of cutting will be performed as the
pivoted blades move from right to left. The
35 movable blades 4 are pivoted at their rear
ends to the back of the base-plate 1, and they
are connected about midway their length by
a cross-bar 5, which is secured to the blades
by a series of screws 6, passing through the
40 cross-bar and engaging theblades and adapted
to regulate the same. The base-plate 1 has
secured to its lower face a stationary handle-
bar 7, the rear portion 8 of which is outwardly
curved and provided with a semi-cylindrical
45 sheet-metal shield or guard 9, the front end
of which is slightly flared and pointed, and
the said stationary handle-bar 7 has pivoted
to it a movable handle-bar 10, that diverges
from the stationary bar 7, and is provided
o50 with a similar shield or guard 11. The piv-
oted blades 4 are operated by a lever 12, thatis pivoted intermediate of its ends to the base-
plate 1, and has one end connected by a screw
13 to the cross-bar 5, and has its other end
connected by a link 14 with a slightly-sig- 55
moidal arm 15, secured to the movable handle-
bar and projecting inward therefrom. The
link 14 and the movable arm travel in the
operation of the device on an upwardly-curved
plate 16, extending laterally from the sta- 6a
tionary handle-bar, whereby as the cutting-
blades come together the rear end of the lever
12 is raised and the said blades are pressed
together to insure cutting. The handles are
maintained normally separated and in posi- 65
tion for cutting by a spring 17, which is ap-
proximately V-shaped, and has the coil 20 at
the apex, and the ends 21 of the spring are
secured to the inner faces of the shields or
guards. 70
From the foregoing description and the ac-
companying drawings the construction, oper-
ation, and advantages of the invention will
readily be understood.
What I claim is-- 75
1. In animal-shears, the combination of
the base-plate provided with blades 2, the
blades 4, pivoted at their rear ends and ar-
ranged to engage with the blades 2, the lever
12, having its front end connected with the 8o
pivoted blades and pivoted intermediate of
its ends to said base-plate, the stationary
handle-bar secured to the base-plate and pro-
vided with the laterally-projecting curved
plate 16, and the movable handle-bar con- 85
nected with the lever 12 and engaging the
curved plate 16, substantially as described.
2. In animal-shears, the combination of
the base-plate provided with stationary blades
2, the movable blades pivoted to the base- 90
plate, the lever 12, having its front end con-
nected with the movable blades, the station-
ary handle-bar 7, provided with the laterally-
projecting curved plate, the movable handle-
bar sliding upon the curved plate and pro- 95
vided with the sigmoidal arm 15, and the link
connecting the arm with the rear end of the
lever 12, substantially as described.
3. In animal-shears, the combination of
the base-plate having stationary blades, the ioo
movable blades 4, pivoted to the base-plate,
the cross-bar 5, connecting the blades, the
