Application med August 5, 191e. Serial No. 955,316.
Be it hewn that l, Lewis E. Annota), a `citizen of theiUnited States, residing at Honolulu, countyl of Honolulu, Territory of Hawaii, have invented certainl new and use ful Improvements in Vacuum-Boxes for 'Fruit-Canning; and l Jdo hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable lothers skilled in the art towhich it appertains to make and use the same. rthis. invention `relates to 'fruit cannlng,
i and particularly to means for subjecting the lao open top lled cans toa vacuum; and the object o1 the -invention is to produce a simple and Ieilicient apparatus for this purpose.
The invention contemplates, a long recs tangu1arshaped'box, a door tor each end, 2li
a plurality' of rollers arranged transversely 'along the bottom of this box, and onvvhich trays bearing a number of the lledopen top cans may be rolled into and out of the box, a pipe provided with a valve connecting' the interior of this box with a suitable air exhausting device, and means for breaking the vacuum, as will hereinafter more tullyappear.. 1
rl'heinventlorrconslsts.1n thenovel construction and combination of parts, reference being had to the accompanying drawings, :terminar a part of this specification, in
Which- A Figure 1 represents in side elevation a preferred form of apparatus embodying my present invention.
Fig. 2 is a section on the line A-A of Fig. 1.
Referring to the drawlngs, 5 is the long rectangular shaped box preferably of cast.v
iron. Each of the doors 6, for closing the ends of the box 5, are hingeably mounted between the outer ends of the arms 7 and 8 on opposite sides of the box 5 respectively. 'lhe arms 7 are pivoted on lthe pins `9 in the sides of the box 5. The arms 8 are piv- 'oted on the pins 1() in the lugs aon the top of the box-V5. Each of the arms 8 is extended at '8a and provided with aweight VV 11 to Aceunterweight the doors 6. Each door '"6 may-#Ehns be, swung` upward to provide access'tothe interio'rof the box 5..4 A gasket 12 may be interposed between the end vof 'opening the valve 19.
theibox 5 and a door 6 to seal the joint when the door is closed.
A plurality of rollers 13, each provided "with trunnions 11 adapted to turn in the notches 15 in the two rectangular bars 16, are arranged transversely within the box 5, as shovvn.
The pipe 17, provided with the valve 1 8,
connects the interior of the box 5 with asuitable air exhausting device. The valve 19, connected by the nipple 2() to the box 5, may be used for breaking the vacuum Within the box 5. lin operation, a door 6 is raised, a tray 2 bearing thereon a number offilled open top cans 22 is pushed into the box 5, and then other trays successively until the box 5 is filled, the trays moving easily upon the rollers 13. -One tray 21 is shown in the draw# 4Spearman. or auraient. Patented Fango, new, y
ings having thereon a'dozen cans '22 although more or less vcans may of course be thus handled. When the box 5 has been filled as described, the door 6 is then lowered until closed, the valve 19 being closed the valve 18 is now opened. The box 5 is thus evacuated to withdraw the air and gases from the fruit inthe cans as well as the air frolnpwithin the box 5, r1`he valve .18 is then vclbsed, and the vacuum is broken by Both doors-filiy are now swung upward and the trays bearing the treated cansv are pushed forward and rolled outward upon the rollers 13 and 'discharged from the box 5 by the insertion of anew set of trays bearingother cans which are to be similarly treated.'
