Application October 23, 1936, Serial No. 107,125
8 Claims.
(Cl. ‘198-21)
This invention relates principally to conveyers
thereof straddle the raised middle portion 2a
Each
connecting link 4 is substantially U-shaped in
plan and is loosely shackled to one adjacent main
link 3 through an opening 9 therein with its open a
end straddling the end of the other adjacent
main link and horizontally pivoted thereto by
means of a. pin l0. ‘Said connecting link is also
provided with outstanding bosses II that sur
round the pivot pin and are adapted for coopera- 10
tion with a sprocket wheel (not shown) for driv
ing the endless conveyer chain.
of the drag chain type wherein the articles are ' of the lower guideway 2 without touching.
carried along by the moving chain. The principal
object of the present invention is to provide for
the automatic transfer or removal of the articles
from conveyers of this type. Other objects are
to control the operation of the transfer mecha
nism by means of the article being transferred
and to provide for strength, durability, simplicity
10 and economy of construction. The invention
consists in the conveyer and in the construction,
combinations and arrangements of parts herein
after described and claimed.
In the accompanying drawings, which form
15 part of this speci?cation and wherein like symbols
refer to like parts wherever they occur,

with an article removing or transferring mecha
nism embodying my invention;

25 conveyer shown in Fig. 2, the transfer mecha

Fig. 6 is a vertical cross section on the line 6—6

thereon with its curved under surface resting on
the opposing end of the upwardly diverging horns

port for said barrel at four separate points there
of clear of the bearing surfaces therebelow with
the center of gravity located between such points.
The conveyer construction thus far described is
more fully set forth in the application of Roy
R. Worrall, Serial No. 9,173, ?led March 4, 1935.
In accordance with the present invention, the 25
above conveyer is provided with a mechanism for
effecting the transfer or removal of the barrels
Cv therefrom at a predetermined point along the
length thereof. This transfer mechanism com
prises a carriage D mounted for sliding movement 30
longitudinally of the conveyer on a slideway made
in Fig. 4;
Fig. 7 is a similar cross section on the line 1-1
in Fig. 5;
Fig. 8 is a side elevation of the pusher support
DO Ul ing carriage; and
Fig. 9 is an end elevation of said carriage.
‘ In the accompanying drawings, my invention is
illustrated in connection witha conveyer compris
ing an endless drag chain A and a suitable sup
4() porting framework B for guideways l and 2 for
slidably supporting the respective upper and low
er runs or reaches of said chain.
By the arrangement described, the barrel C is
rolled or otherwise positioned on the upper run of
Said chain
comprises main article supporting links 3 alter
nating with connecting links 4. Each main link
45 3 has a ?at bottom portion 5 with a bearing sur
face suitable for sliding on the upper guideway
l and a top portion 6 with a bearing surface suit
able for sliding on the middle portion 2a of the
lower guideway 2 when said link is in inverted
50 position. The top portion 6 of the link 3 has
horns l alongside of its bearing surface that ex
tend upwardly far enough in the upright posi
tion of said link to support a keg or similar arti
cle C thereof clear of said bearing surface. In
55 the inverted position of the link 3, the horns 1
up of spaced parallel angle irons l2 suitably se
cured to the framework B of the conveyer just
below the upper guideway l thereof. The car
riage comprises a bottom plate l3 slidable on the 35
angle irons l2 beneath the upper guideway I and
having upstanding guide flanges I4 disposed
alongside of said guideway.
The carriage D is
provided on one side of said upper guideway with
an upwardly and inwardly inclined slideway I5 40
adapted to receive a push plate Hi. This pusher
I6 is provided at its lower end with a roller l1
and at its upper end with a head portion l8 that
is shaped to ?t the bilge of a barrel 0. The
roller H at the lower end of the pusher I6 travels 45
along a cam track [9 that is secured to and ex
tends longitudinally of the conveyer frame B and.
is offset upwardly, as at 20, so as to slide said
pusher upwardly in the inclined slideway 15 on
the carriage when the latter moves in the direc- 50
tion of travel of the upper stretch of the chain A
and causes said roller to engage the upwardly
offset portion of said cam track.
Pivoted for vertical swinging movement on
outstanding horizontal pivots 2| provided there- 55

for on opposite sides of the carriage D are arms
22 that extend forwardly alongside of the carriage
in the direction of the travel of the upper stretch
of the chain and terminate in upwardly inclined
free end portions that are connected by a cross
bar 23 located above said upper stretch. The
cross bar 23 is normally held clear of the conveyer
chain and in the path of the barrels by means of a
weight 24 ?xed to a rearward extension 220, of one
10 of the arms 22, the upward swinging movement
of said cross bar being limited by a pin 25 ?xed to
the carriage and adapted to be engaged by said
extension. The carriage is yieldably held in its
normal or retracted position against upright
15 members 26 of the conveyer frame by means
of helical tension springs 21 having one end ?xed
to the pivots 2| for the arms 22 and the other end
?xed to a bracket 28 secured to said frame rear
wardly of said pivot. When a barrel C reaches
20 the transfer mechanism, the convexly curved
underside of its forward end portion presses
against the cross bar 23 and gradually forces
said bar downwardly into the path of the up
standing horns I of one of the main links 3 of
25 the chain; and the pressure of said horns against
said cross bar causes the carriage D to move with
the chain against the tension of the carriage re
tracting springs 21. This movement of the car
riage causes the roller I‘! at the end of the pusher
[6 to roll upwardly along the upwardly inclined
portion of the cam track 19 and thus force the
upper end l8 of said bar against the side of the
barrel and thus roll the same off the conveyer.
As the barrel, when in engagement with the cross
35 bar 22, holds said bar in engagement with the
chain, the removal of said barrel permits said bar
to swing upwardly clear of the chain; whereupon,
the carriage is returned to its original position by
the retracting springs 21. The barrel may be
transferred to another conveyor 29 or chute
shown in Fig. 1, or it may simply remove the
article from the conveyer.
Obviously, the hereinbefore described conveyer
admits of considerable modi?cation without de
45 parting from the invention. Therefore, I do not
wish to be limited to the precise construction
shown and described.
What I claim is:
1. In a conveyer having a conveying element,
50 mechanism for removing articles from the mov
ing conveying element comprising a carriage
movable longitudinally of said element, a mem
