In‘the manufacture of screw eyes, automatic
machinery has been developed for forming the
eye portion of the screw eye by bending the un
threaded end‘of a threaded blank to substan
tially ‘circular form. This machinery is equipped
10 with automatic feed mechanism for feeding the
blanks to the bending dies. However, it is neces
sary to have all of the blanks with the threaded
ends extending in one direction‘ in the forming
process.

supplied with electric current in any suitable 15
manner and upon its operation drives a shaft 13

are held apart by a pair of spacers 50 and 5|,
being held on the plate 35 by means of machine
screws 52.
Supported by the upright members 33 and 34
adjacent their upper ends are a pair of pivot
thereto which extends between the jaws of a
10 bifurcated member 58 carried by the shaft 3|
and the rocker arms 55 and 56 are joined to
gether at their bottom ends by a blank carrier
59, which is secured to the lower ends of the
rocker arms by means of machine screws 60 so
15 that each time the shaft 3| is rocked by the ec
centric drive |2, the rocker arms 55 will move
the blank carrier back and forth beneath the
slot 45. The shaft 3| carries, in addition to the
bifurcated member 58, a pair of levers 6|, the
20 forward ends of which extend through slots
62-62 and 63-63 in the plate 65 and the rear
plate 41 for the purpose of agitating the screw
eye blanks 44 in the magazine 31 to insure that
they will not jam at the mouth of the slot 45.
25 The carrier 59 has a pair of slots 69 and ‘I8
formed therein for receiving screw eye blanks
from the slot 45 and carrying them to the right
or left from the slot 45, Figs. 2, 3, 4, and 5, to
deposit the blanks on knife edged selectors ‘II,
80 ‘I2, ‘I3, and ‘I4. The selectors ‘I3 and ‘I4 are ?xed
to the plate 36 and the selectors ‘II and ‘I2 are
pivotally mounted thereon, being adapted to os
cillate about a pin 15, a pair of springs ‘I6 and
‘I1 normally tending to rotate the selectors ‘II
35 and ‘I2 in a clockwise direction about the pin ‘I5
which is mounted in the plate 36. Each of the
selectors 1|, ‘I2, ‘I3, and ‘I4 has a V-shaped knife
edge formed thereon as shown at ‘I8, ‘I9, 88, and
8|, which will tend to hold the threaded ends of
edged selector ‘I2 will be in the position shown in
As the carrier 59 moves to the
left, Figs. 2, 4, and 5, it will cam the selector ‘I2
in a counter-clockwise direction, Fig. 1, and the 10
threaded blank 44, if the threaded end thereof
extends to the left, Fig. 1, will be pulled off of
the knife edge 8| and will drop into the tapered
trough 98 with the unthreaded end extending
downwardly. Similarly, if the threaded end of
the blank 44 extends to the right, Fig. 1, the
knife edge 8| will tend to hold the blank and
the knife edge ‘I9 will move out from under the
unthreaded end of the blank, permitting the
blank to fall into the tapered trough 90 with the 20
unthreaded end downward.
If, in the feeding of parts from the .slot 45 to
the carrier, an end of a blank catches in one of
the slots 69 or ‘I0 while the other end thereof is
still in the slot 45, or for some other reason the
carrier. 59 or levers 6| encounter excessive re
sistance to their normal movement, the eccentric
device I2 will continue to move but rod |6 will
not move due to the ball and groove connection
between the eccentric and rod. In this manner,
damage to the machine is avoided.
Although a specific embodiment of the inven
tion has been disclosed herein, it will be under
stood that many modiflcations inay be made in
the machine without departing from the scope
of the appended claims.
'
What is claimed is:
1. An article handling apparatus for sorting
blanks comprising a. rocking carrier, a magazine
for feeding parts to said carrier, a pair of knife 40
40. blanks on whichever one of the knife edges the
threaded end of the blank happens to fall when ' edged selectors associated ‘with said carrier for
the selectors 'II and ‘I2 are rocked about the pin receiving a blank from the carrier, and means
for moving one of said selectors to cause a blank
‘I5 in a counterclockwise direction. The mecha
nism for rocking the selectors ‘II and 12 in a positioned on a pair of selectors to drop there
45 counter-clockwise direction comprises a pair of from with a predetermined end of the blank
pins 85 and 86 mounted in the carrier 59 and downward.
2. An apparatus for sorting threaded blanks, a cooperating with cam surfaces 81 and 88 formed
magazine for receiving a plurality of threaded
on the selectors ‘II and ‘I2.
'
Positioned beneath the selectors ‘I|, ‘I2, 13, and blanks; a rocking carrier associated with said
magazine to take blanks therefrom one at a 50
50 ‘I4 is a tapered trough 98 which is ?xed to the
upright member 34 and which terminates in a time, a pair of selectors adjacent said carrier
for receiving blanks therefrom, and means for
feed pipe 9| so that blanks 44 which are de
posited in the magazine 31 and passed therefrom
to the selectors will be directed to the pipe 9|
55 with their threaded ends upwardly. The pipe
9| may extend to a suitable container for receiv
ing the threaded blanks or it may be utilized to
feed the parts directly to the magazine of a
bending machine for forming the threaded blanks
60 into screw eyes.
It is believed that a better understanding of
the invention may be had from the following
brief description of the operation thereof.
.
If a plurality of blanks, such as those shown at
65 44, having one end thereof threaded, are placed
in the magazine 31 with the threaded ends ex
tending to either the right or left at random,
Fig. 1, the blanks will tend to roll down intothe
slot 45, the lever 6| tending to agitate the blanks
70 in the lower end of the magazine so that the
blanks will all lie horizontally in the slot 45 from
which the blanks will drop into the slots 69 and
‘III of the carrier 59 and will be moved to posi
tion over either the selectors ‘I2 and ‘I4 or over
the selectors ‘II and ‘I3 as the carrier is oscillated
oscillating one of said selectors to cause a blank
to drop between the selectors with a predeter
mined end thereof downward.
55
3. An apparatus for sorting threaded blanks
comprising a magazine, a carrier associated with
said magazine for receiving blanks therefrom, a
pair of selectors spaced apart a distance less
than the length of the blank for receiving a 60
blank from the carrier, and means for moving
one of said selectors away from the other a pre
determined distance to cause the blanks to drop
off of the selectors with a predetermined end
thereof downward.
