The invention relates to a machine for cutting slices .of fruits, such, for example, as pineapples, into half slices and'is especially adapted to the treatment of damagedv or imhalf slices may be cut, the initial slices being assembled in par,

allel relation'in a trough with the good por- .tionsof the respective slices disposed withinthe trough, then cutting off the portions '10 of the slices projecting beyondv the 'upper edges of the trough by means of'a reciprocating knife moving longitudinally of and parallelwith said upper edges, the-troughbeingpivoted at one end and held operative engaging the other end, whereby, when the latch is tripped, the

- trough will swing downwardly and discharge the severed half slices, preferably into cans or other containers which are supported in 20 proper position on the machine to receivethe half slices.

The invention is illustrated in the accompanying drawings, in which -;Fig. ,1 is a side elevation.

Referring to the drawings, 1 indicates a bracket-like casting having a flat top or table section adapted to support a can or otheroreceptacle in which the product is to be packed, said bracket having a clamp 2 adapted to en= gage a perpendicular flange on a packing I table. with which the machine is to be associated. .IBoltedto the bracket l'are two parallel side framemembers preferablyformed of channelbars, each member comprising a lower perpendicular section 3 and a rearwardly inclined section 3,the sections 3 and 2 guide for thefknife. faces of the strips or frame members 3' is swingthelatter into V engagedby the latch 12 andto limit the outfiinember 4, which also constitutes anabutment for the stack of slices assembled the machine. a

Pivotedto bearingblocksltisecured to thea swinging bail 15, which embraces the trough and serves to normal position to be ward swinging movement of the trough, when the latter is released, said bail preferably being providedwith extensions 15' on either sideof the machine by means of which the bail may be operated to swing the trough: into closed position, as indicated more particularl inFigs.1and3. y hf ounted between the side members 3 and slidable longitudinally thereof is a flat knife 20 mounted on a support 21,-the lateral edges of which engage the. grooves in the battens 5, 5Qto guide the knife parallel with and in; close proximityto the upper edges of the trough 10, as indicated in Fig. 4. The said supportis provided with upturned ears 22 1 between which is secured a handle 23 and the front or lower portion of the support is bent 3' being secured together by gfiatf plates or Attached to the upper Y Pivotedby cross pin'11 170 ,of a spring bolt 12 slidably mounted on the upward and backward to form a shield 24 having undercut sides to overhang the

guard strips

6, 6, the shields serving to, force the upper portions of the cut fruit to the point, of ultimate discharge.

r batch of imperfect or Mounted on face plates 25, 25 spanning the upper ends of the side members 3' is a spring motor 26, which may be of any approved type and which is conventionally illustrated in Figs. 7 and 8, adapted to automatically wind up the cable 27, one end of which is attached to the support 22, said spring motor serving to retract or return the knife and its support to the upper or inoperative position, as indicated in full lines in Figs. 1 and 3.

To adapt the machine for cutting slices or disks of smaller diameters, there is preferably provided one or more attachments or filler blocks of the character indicated at 30 in Fig. 9. These may be of an external diameter adapted to fit the interior contour of the trough 10 and an inner diameter to accommodate the curvature of the particular slices to be cut, the selected filler being secured to the inner face of the trough by clamps, screws or any other appropriate means.

The operation of the machine is as follows: The machine is mounted on the feed table in the relation indicated in Fig. 1, so that the attendant may select the damaged or imperfect slices passing over the feed table and stack the selected slices in edgewise relation in the trough 10 with the unimpaired portions of the slices lying within the body of the trough and the damaged or impaired portions extending above the edges of the trough. When a sufficient number of slices have been thus assembled in the trough, the operator moves the knife 20 downward by means of the handle 23, against the tension of the spring drum 26, thereby cutting off the projecting tops or upper portions of the slices, leaving the series of perfect half slices in the trough and ultimately forcing the severed upper portions of the slices 011' the lower end of the machine onto the belt or other conveyor usually associated with the packing table, by Which the severed portions aredelivered to the apparatus employed for converting the same into crushed fruit. After the cutting operation has been completed, by the movement of the knife throughout the entire length of the trough, the operator releases the knife, which is immediately returned to inoperative position by the spring motor 26. The operator then actuates the latch 12, which releases the lower end of the trough, thereby permitting the trough to swing outward and discharge the half slices therein into a can or other receptacle mounted on the bracket 1, as indicated in Fig. 1, the outward movement of the trough being limited by the bail 15. When the out half slices have been discharged from the trough, the latter is swung back into normal position by the opeator swinging the bail 15 by either handle 15' until the lower end of the trough snaps behind the nose of the latch 12 and the machine is then in condition to receive the next damaged slices to be out .said trough, and

into half slices by the succeeding operation of the knife.
