Application November 28, 1936, Serial No. 113,232
5 Claims.
My invention relates to apparatus for shearing
metal and the object of my improvement is to
perfect the operative construction, and to facili
tate the presentation of the material to the ap
5 paratus and its disposition after it has been
'
acted upon.
In the accompanying drawings, Figure 1 is a
'side view of an apparatus embodying my inven
tion.

Figure 2 is an elevation looking from the right
of Figure 1, the jaw being shown as closed down
to cutting position.
Figure 3 is a sectional elevation on the line
3-3, Figure 2, the frame 6| being shown turned
15 down in position to receive the work 64, thereon.
Figure 4 is a detail perspective view, illustrat
ing the take-up construction of the bearing for
the main shaft.

ends of the portions 8, 8. Bolts 6, 6 pass
through said plates and in screw-threaded aper
tures in the frame 2. Numerals ‘l, 1 denote 5
bronze plates interposed between the side sur
faces of the jaw |, and the adjacent surfaces of
the frame 2. The bolts 6, press the bronze plates
7 against jaw I thus serving to adjust the jaw
laterally. The plates 1 have grease cups l0, and
passages to supply grease to the contiguous sur
faces of said jaw and plates. Numerals || indi

Power is communicated to the cutting appa
ratus by means of a belt 40 (Figure 9) passing
over a pulley 69 upon the shaft 4|, mounted in

22, 22 are flywheels
43, 43 are pinions on the shaft
in bearings 32 thereon. Numerals 2|, 2| desig~
nate gear wheels on the outer ends of said shaft
with which the pinions 43—43 mesh. Numerals
33, 33 (Figure 6) denote two arms, and 39 a con
necting pin, of a crank upon the shaft 38.v Nu
meral 29 indicates a connecting rod pivoted at
its lower end upon the pin 39, and at its upper
chine resting upon blocks 5|, and | indicates a end upon a pin 36, extending transversely
swinging jaw secured to a shaft 3, adapted to through the walls of a slot in the end 39, of the
oscillate in bearings in the upper end of upright jaw |. Bronze plates 31 are interposed between
the sides of the connecting rod 29, at its upper
members projecting from the frame 2. Nu
40 merals 66 (Figure 5) is a
key securing the shaft end and the side walls of said slot in the jaw |.
Set screws 3|, 3| pass through the walls of said
3, to the jaw |. Numerals 9, 9 denote grease con
duits opening at the ends of the shaft 3, and at slot and engage the plates 31 to press the same
against the connecting rod to adjust it laterally
the periphery of said shaft within its bearings.
The ends of the shaft 3, are screw threaded, and thus obviate any lost action.
45 and caps 4, 4 internally screw-threaded engage
Numerals 26, 26 denote posts, integral with the
the threads on the end of said shaft. The caps frame 2 and rising vertically therefrom upon
4,4 are adapted at 65, 65 to be engaged by a opposite sides of the jaw |. A bolt 34, (Figure 7)
connects the upper ends of the posts 26 and is
wrench, for adjustment or removal. The nu
meral 8 denotes a part shaped to form the lower ?tted with adjustable nuts 21, at each end. The

jaw | has steel plates 28, welded to its sides
lower surface of said part tapers inwardly and which slide upon the bronze plates 35. Set
screws '1 I, press bronze plates 35 against the steel 0

plates 28 which also tend to move the jaw |
sponding Wall of the opening in the frame 2,
through which said shaft passes (Figures 4 and laterally.
The jaw I has a knife 10, which shears past

knife ‘Illa on the frame 2 (Figures 1 and 2).

The gear wheels 2!, mesh with pinions 20 on a
transverse shaft 23, ?tted with a sprocket wheel
14, at its outer ends. The numeral l3 denotes ‘a
shaft parallel to the shaft 23, having sprocket
wheel Bl at its outer ends. Numeral I9 desig
nates a sprocket ‘chain passing over and connect
ing the sprocket wheels l4 and 61.
Numeral l5 indicates a bevel gear on the shaft
I3. Numeral l8 denotes a table at one side of
10 the frame 2 at the delivery end of the apparatus.
Numeral Z5 denotes a roller beneath the table
l8, its shaft extending at right angles to the
shaft I3, and having a bevel gear 24. Numeral
l5 (Figures 2 and 9) designates a conveyor pass
ing around, and actuated by a driving roller 25.
The table l8 has slots 52 in its upper wall and
the conveyor is provided with prongs l‘! which
pass through said slots to engage any object on
the table l8. Numeral 12 denotes a curved de
livery surface extending from the cutter 10a to
the table l8.
‘Numeral 4T designatesa table connected to the
frame 2 by lugs 59 pivoted to the upper ends of
vertical levers 48-—which levers are secured to
bolts 59 at their lower ends, that engage the
frame 2. As said bolts are loosened levers 48
swing ‘down lowering the table as illustrated in
broken lines (Figure 8).
The following apparatus is used for handling
30 large parts such as automobile frames. Numeral
54 (Figures 1 and 3) denotes a trough in the
?oor 68. Numeral 56 indicates a plate supported
in the trough 54 by springs 55. Numeral 56a
denotes a guide plate for the side of the carrier
which may be adjusted laterally by hand screws
‘51. Numeral 58 designates a carrier provided
with wheels 62, resting upon and adapted to
travel longitudinally on the plate 56. The car
rier 58 has a rigid fence 59 at one end and side
40
to prevent work falling therefrom. Numeral Bl
vindicates a movable frame pivoted at 6!! to the
side of
the car 58, so as to swing in a vertical
plane. The frame 5| is turned down and the
work placed thereon as shown in Figure 3. The
45 frame is then turned up dropping the work into
"the carrier which is then manually pushed for
ward, and the work 64 is made to lean over to
bring a. portion of it between the cutters (Figure
1)‘. The fragments 13 slide down the incline 12
50 onto the table l8, from which they areremoved
"by the prongs H on the conveyor l5.
'
Smaller articles are ‘placed upon the table ET,
and passed therefrom to the. cutters. With large
parts there is apt to be lost motion between the
work and the lower cutter as the work yields
to the descending jaw l, the springs 55 yield
to the thrust.
Numerals 63 denote chains secured to the
frame 2, and the carrier 58, to limit the travel of
the latter.

What I claim is:
1. In an apparatus of the kind described, an
oscillating jaw, two posts located opposite to each
other adjacent to the sides of said jaw and spaced
from the pivotal axis of. said jaw, and means for
15
adjusting the distance apart of said posts.
2. In an apparatus of the kind described, an
oscillating jaw, two posts located opposite to
each other adjacent to the sides of said jaw and
spaced from the pivotal axis of said jaw, and
means for adjusting the distance apart of said 20
posts, a plate interposed between one, of said
posts and the side of said jaw and means for
adjusting said plate at right angles to the. plane,
of oscillation of said jaw.
3. In an apparatus of. the kind described, the
combination of a cutter, a trough-like structure
passing transversely in front of said cutter, a
plate in said structure forming a Way for a car-
rier, springs supporting said plate, and a carrier
30.
adapted to travel upon said plate.
4. In an apparatus of the kind described, the
combination of a cutter; a plate forming a way
for a carrier and extending transversely in front
of said cutter adjacent thereto; springs support
ing said plate; and a carrier adapted to travel
upon said plate, substantially I as and for the
purpose described.
5. In a machine for shearing automobile
frames, an oscillating jaw having a shaft; a
bearing for said shaft, two posts located opposite
each other adjacent to the sides of said jaw and
means for adjusting and ?xing the distance
apart between said posts, said jaw having a
shearing edge; a stationary shearing edge adapt
ed to coact with said shearing edge upon said
jaw; and a spring-supported plate adapted to
receive an automobile frame and hold a portion
thereof adjacent to said stationary shearing edge
and in the line of travel of said shearing edge
on said jaw.
