In order that baked loaves being transferred

tilt sideways into the triangular space between
the end. of the conveyor 2_ and apron l6 of the
elevator. an auxiliary‘driven roller 21 is provided.
This roller is journaled in the side frames I and,
as shown in Fig. 7, is positioned just below the
level of the belt conveyor 2 and inthe space
between the depending apron portion In of the
elevator and the loading conveyor.

The table 26 extends over and above the level
of the ?ight feed conveyor 3, so that the ?ights
~75 ~thereof can pass under the table at ‘the begin
portion 41 engageable with the under side of the
above mentioned apron to limit upward motion
of table 36. The angularity of the tongue 45
and the apron 36 with respect to the table 36 is
such that the up and down motion of the table
is relatively gradual, due to the action of the
?ights of the conveyor 8 riding over the tongue
and apron as will be hereinafter described and‘
preventing a snapping up of the table because
of a sudden release.

The loaves are supported on a conveyor apron 49
which is carried on and rigidly secured to raised
25 portions 5| of cross members 58 that extend be

supported above the cross members 58 so as to

In order to facilitate the transfer of articles

,transfer wheels I83 may be provided. These‘
wheels are mounted on and driven by shaft I6I,
which also carries the rearward sprockets I60,
and are arranged to project through suitable slots
40 I84 in the conveyor table I55, so that they ‘are
substantially even with the table I5I.

feed conveyor in a similar manner, the cycle thus 20
being repeated to position an article between each
pair of ?ights of the flight feed conveyor and
provide a timed regulated procession of articles
through the slicing mechanism.
.
.As an article slides off the table I5I under the 25
in?uence of gravity and a ?ight I51, the forward
edge is engaged and supported by the transfer
wheels I83.- Rotation of the wheels carries the
article onto the conveyor table I55 and effects -
smooth transferthereof, so that thc article does 30
not tip over to be improperly fed to the slicing
mechanism;
It will thus be seen that the present invention
provides an infeed timer for a slicing machine
which is arranged to receive a number of articles 35
simultaneously, straighten and align such arti
cles and individually feed them to the slicing
mechanism at regulated intervals.
- Furthermore, it is to be noted that‘ an infeed
