FRUIT HOLDER.
Norman E.V Gaddini, Winters, Calif.
Application April 14, 1945, Serial No. 588,335
19 Claims. (Cl. 146~--28)
1
The present invention relates in general to the
art of automatic fruit machinery, and especially
machinery of such character adapted to accom
plish mechanical halving and pitting of stone
fruit, such as peaches and apricots. The present
invention is a continuation in part of application,
Serial No. 533,548, ñled May i, 1944, which dis
closes a machine of the above type.

finally removing the cut-apart fruitJ halves from

A further object of the invention is to provide
a useful and effective fruit holder for the purpose
for which it is designed.
These objects are accomplished by means of
such structure and relative arrangement of parts
as will fully appear by a perusal `of the following
individual fruit holder of novel construction 10 specification and claims.

When an automatic fruit machine embodying
the above described holders is in operation, said

are disposed in the holder between the sides 5
thereof; said base plates being spaced apart
slightly in the direction of travel and parallel
transversely of the holder. The base plates are
normally horizontal and alined in the manner
shown in Fig. 2.
Each base plate 9 is provided, on its upper
surface, with a relatively thick pad Ill of sponge
rubber or the like, said pads being formed at ad
jacent ends with complementary or matching
cupped seats II, each seat including large> and
small diameter portions, as shown, for support
ing engagement with fruit of corresponding sizes.
Pairs of transversely spaced vertical spikes I2 are
secured in connection with the base plates 9
near the adjacent edges thereof, said spikes pro
jecting upwardly through the cupped seats I I and
being disposed in substantially equallyV spaced
symmetrical relation to each other. At their
lower ends the spikes I2 engage in sockets I3 in
an increased-thickness portion of the base plates
9, and the spikes are retained in said sockets
w by set screws I4. For small Vsize fruit, such as
apricots, the spikes I2 may be removed from the
sockets I3 and shorter spikes placed in other and
more closely spaced sockets I5; the set screws I4
being arranged to cooperate with spikes in either
set of sockets.
At their upper ends the spikes I2 are bevel
sharpened, with the bevel facing centrally in
wardly for the purpose of preventing fruit pits
from impaling on said spikes and assuring that
the pits engage between the latter, as will here
through several different predetermined stations.
At one station individual fruit 28, with the stem
end uppermost, and with the suture facing lat
erally, is impaled on the spikes I2 with the pit
29 of the fruit disposed centrally of said spikes.
The fruit. engages on and is- supported by the
cupped seats Il; the spikes I2 corresponding to
one base plate projecting into one fruit half 30,
while the spikes I 2 corresponding to the other
base' plate project into the other fruit half.
At successive steps the fruit is cut to the pit
down opposite sides, as at 3|, and across the
bottom, as at 32. After the fruit is so cut, the
holder 3 moves to a pit ejecting station, indicat
ed generally at 33. The side and bottom cutting
of the fruit, together with movement of each hold-er' through the successive stations is described in
some detail in the above identiñed copending ap
plication.
After the holder 3 reaches the pit ejecting sta
tion 33 and stops at such station, a pair of trans
versely spaced, downwardly projecting tongue
like cams 34 engage between corresponding roller
extensions 22 which are moved apart by continu
ing downward movement of said cams, the latter
functioning in exact predetermined timed rela
tion t0 movement of the holder 3 to position at
the station 28. As the roller extensions 22 are
moved apart equally in opposite directions, a cor
responding movement is imparted to the base
plates 9; the rollers then moving along the cam
slots I9. Due to the shape of the cam slots I9
the rollers 2| elevate relative to the rollers 20,
causing the base plates to tip upwardly at their
inafter appear.
The base plates 9 are each supported, from be
outer edges at the same time that the separat
