FASTENING-INVERTING MECHANISM
Thomas H. Seely, Melrose, Mass, assignor to
United Shoe Machinery Corporation, Paterson,
N. 3., a corporation of New Jersey
Application June 18, 1936, Serial No. 85,883
26 Claims.
,
This invention relates to mechanisms for in
verting fastenings, and particularly to those by
which nails, screws or the like are received with
their heads or points arranged in one direction
5 and are so turned that they are oppositely posi
tioned.
'
-
Fastening-distributing apparatus, of which an
example is disclosed in Letters Patent, of the
United States No. 1,948,499, Bertrand, February
10 27,1934, are organized to deliver successive loads,
each made up of a de?nite number of fastenings.
{Each load leaves the distributor with all its fas
tenings arranged with the heads or points in the
same direction. In the machine by which the
15 fastenings are to be utilized, it may be desirable
to receive said fastenings oppositely arranged.
The present invention therefore has as an object
the provision of a simple mechanism by which
successively received fastenings or groups thereof
20 may be inverted by applied forces which make
certain the eifect sought, this mechanism being
of such a character that danger of clogging, is
minimized. This object I attain by the employ
.
ment of a movable member having a receiving
25 surface in constant fastening-receiving relation
to an inclined delivery-tube or conduit, the mem
ber being movable in a direction opposite to the
inclination of the-conduit to effect the inversion.
‘The movement of the inverting member is pref
30 erably one of rotation and is best continuous, and
its fastening-receiving surface is smooth and un
broken. A stop extending over the receiving sur
face may be used to limit the movement of the
fastenings over such surface upon their discharge
35 from the delivery-conduits, and the inverted fas
tenings may be received by conduits opening be
low the member. Since the fastenings are ordi
narily supplied in loads, a plurality of both the
delivery-conduits and the receiving conduits with
40 their associated stops are provided, all co-op
crating with a single inverting member. Two
forms of the inverting mechanism are especially
effective. One has a cylinder rotatable about a
substantially horizontal axis, while the other uti
45 lizes a plate turning about a substantially vertical
.axis. In the ?rst form, the cylinder is shown as
having a groove, a delivery-conduit depositing
the fastenings in the groove, while a stop ex
tends into- the groove. The plate appears as
50 provided with a downwardly and outwardly in
clined marginal surface, which receives the fas~
tenings from a delivery-conduit and has a stop
extending over it. Whatever form is employed,
the engagement of the receiving surface of the
I 55 movable member applies to the delivered fasten
(Cl. 1-39)
ings a constant mechanical force, as distinguished
from themere e?ect of gravity, through which
force their inversion is brought about; and the
mechanism is entirely free from fastening-re-.
ceiving pockets and from passages with angularly 5
related walls, both of which arrangements are
liable to cause clogging. Great simplicity re
sults, from the use of a single movable element
constantly actuated in one direction only, With-,
out the inclusion of cams or other wear-pro- '10
ducing actuating means.

eral possible embodiments of my invention are

Referring to Figs. 1 and 2, we have a casing
l0 arranged to be secured upon the frame of a _
fastening-distributor or upon the machine by 25
which the fastenings are to be used. The casing
has a horizontal, cylindrical bore, and within this
is arranged to turn a fastening-inverting cylinder
I2 carried by a horizontal shaft M. By this
shaft, the cylinder may be rotated in the direc- 30
tion of the arrow in Fig. 1 in synchronism with
the elements of an associated distributor (not
illustrated), which delivers the fastenings to the
inverting mechanism. In the cylinder is shown
a series of circumferential grooves l6 situated side 35
by side, while there may be registering grooves l8
in the casing forming therewith passages for the
fastenings. Leading into each passage I6, l8, at
approximately the highest portion, through the
top of the casing is a short passage 20 to which 40
delivers a tube or conduit 22 by which fastenings
are conducted from the distributor to the in
verting mechanism. The upper portion of the
tube is shown as vertical, but, as it approaches the
casing IE, it turns by a gradual bend until it 45
enters the passage 29 at 24. Both this portion of
the tube and the passage are inclined downwardly
and forwardly in a direction opposite to the ro
tary movement of the adjacent portion of the
cylinder, being substantially tangential with re- 50
spect to the cylinder-passage. At the bottom of
the casing is a short delivery-passage 26, from
which leads a tube 21 arranged similarly to the
tube 22 with a tangential portion 28 but opening
from the casing at the opposite side of a vertical 55
2
2,105,377
plane through the axis of rotation. Through a
longitudinal slot in the casing near its top is
clamped a bar 30 having projections 32 extending
into the cylinder-grooves i8. These projections
furnish stops located in the paths of the fasten
ings as these are discharged from the passages 2t
and are at the upgoing side of the cylinder.
In the operation of the mechanism, each of the
series of passages and tubes functions in pre
10 cisely the same manner and may be reduced or
multiplied in number in accordance with the re
quirements of the machine supplied. Power be
ing applied continuously to the shaft l4, and the.
Screws S are shown in Figs. 3 and 4 as being
inverted. They descend, points first, through the
tubes 5i] and are delivered therefrom upon the
surface 48, being limited in their discharge-move
ment by the stops 54 toward which they are pro
jected. When the mechanism is applied to the
inversion of a plurality of screws, the stops pre
vent interference between screws delivered by
different tubes. The rotation of the plate car
ries the delivered screws, in a direction opposite
to that of their reception, along the inner sur
