9 Claims. (Cl. 218-6)
My present invention relates to a button feed
ing and positioning or orienting mechanism for
a button-attaching machine, and more particu
larly constitutes an improvement on the mecha
5 nism disclosed in the patent to Miller No.
2,067,225.
In the above mentioned patent to Miller there
is disclosed a machine for feeding and orienting
buttons having a design on their top, and means
l0 on the button bearing a deñnite relation to the
design, which means cooperates with a part of
the mechanism for orienting the design on the
button, and for presenting the button in orient
ed position to the attaching station of the ma
1l chine. 'The orienting mechanism therein dis
closed comprises a rotary member which func

`
In ,suitable bearings 44, 45, mounted respec
tively on the rails I2 »and I3, is a stud shaft 46
upon which is ñxedly mounted the hub of a lever
41 and adjacent thereto, the hub of a lever 48._
The lever 41 has an upwardly directed portion `
30 49 formed with a socket or recess 49' on the face
thereof adjacent the track and a downwardly
extending portion 58, the free end of which is
bifurcated, as indicated at 50’.v Mounted in the
-bifurcated end 50' of the lever portion 49 is a
35 locator pin 5I which extends inwardly toward
the track I0 at the registering station thereof and
is normally held in a position to engage the tab
on the button as the latter is rotated about its
axis in the course of being oriented at said regis
40 tering station.
For normally holding the pin in
said last-mentioned position, an expansion spring
52 acts upon the upwardly-extending portion 49
of the lever 41, one end of said spring engaging
in the socket 49' and the other end being mounted
45 in a socket formed in the rail I3. The lever 48
has a downwardly-extending offset portion, the
free end of which is bifurcated, as indicated at 53,
and mounted in said bifurcated endis a roller 54
which is adapted to be engaged by the cam surface
50 42 on the gear sector as it approaches the down
ward limit of its movement to rotate the shaft 46
to move the locator pin outwardly with respect
to the track against the tension of the spring 52._
Extending outwardlyfrom a side wall of the
55 track frame somewhat above the registering sta
tion and slightly above the horizontal plane of
the shaft 46 is a lug or ear 51 upon which is piv
oted the bifurcated upper end 58 of a lever 69,
the lower end of which is also bifurcated and
60 has pivotally connected thereto, as at 59', one end
of a lever 60, which latter lever extends laterally
outwardly with respect _to the track. At its end
remote from the track, the lever 60 is formed
with a socket 6I within which is mounted a
65 spring-pressed pin 62 so that the top thereof
extends above the end of the socket, as best
shown in Figs. 2 and 3. The end of the lever 60
moved to engage a button at the registering
station and transfer it in oriented position to the
jaws (not shown) at an attaching or setting sta
tion 1I. To permit of this action by the pusher
rod 10 the latter is formed with a terminal recess
or bifurcation 12 for engaging and receiving the 30
button as the pusher rod is moved in the direction
of the arrow in Fig, 1, the bottom face of the
pusher rod being longitudinally grooved as indi
cated at 13, to clear the top of the disk 61 during
the button transferring operation.
Operation-The buttons are first fed by any
suitable means, preferably by a hopper (not
shown), to the track or raceway I0 until the
track becomes loaded with buttons, the bottom
button resting against the periphery of the cut
off disk 28. Asthe machine is operated, a rota
tive movement is imparted to the cut-olf disk 28,
bringing the recess 2I thereof into button receiv
ing position, that is, in position to receive the
hub of a button. Rotation of the cut-off disk 20
is controlled by movement of the gear sector 36
and the rod 30 carried thereby as the follower
roller 38 of the lever 31 moves over the cam
surface 39, the movement in either direction being
limited by engagement of the pin 24 with the 50
side _of the track frame. As the gear sector 36
is moving downwardly a button will be cut off from
the track I0 by the disk 20, and a button which
will already have been received in the disk 20
will be carried thereby for delivery to the button
registering station between the disks 66, 61 and 68.
As the gear sector approaches the end of its
downward movement, the projection 4I thereon
will engage and push down the pin 62 on the lever
60, which will swing outwardly the lever 59 with 60
the spur gear 65„and disk 66 thereon a distance
equal to the amount that the teeth on the upper
end of the gear sector 36' are cut back. This
movement is brought about by engagement of the
lug 63 against the side frame of the machine, caus 65
ing the lever 59 to move outwardly about its pivot
point on the lug 51. Substantially simultane
adjacent its pivoted connection with the lever 59 . ous with this movement of the lever 59, the cam
is formed with a lug 63 which normally bears surface 42 on the gear sector will engage the
70 against the side of track rail I3. The projecting
end of the pin 62 is adapted to be engaged by
the lug 4I as the gear sector 36 approaches the
end of its downward movement and thereby rock
the lever 60, and with it„ the lever 59 about its
75 pivoted end 58.
roller 54 to rotate the shaft 46 to move the 70
locator pin 5I outwardly, so that the button
carried by the cut-off disk can drop down between
the disks 66 and 68 to the registering station to
be oriented thereat. When the gear sector is`
moving upwardly the locator pin 5I will return 75

_to its locating position under the tension of spring
52, the spur gear 65 will be rotated and with it
the disk 66, to spin the button about its axis
which will be stationary until the tab I8 on the
button engages the locator pin. When this takes
place, the button in oriented- position will be
held against further rotation, whereupon the
pusher rod 10 is moved inwardly to engage the
button and transfer it in its oriented relation from

attaching station 1I.
