simultaneously such severable solid products as I pineapples or the like.

Prior to my invention such severable solid products as pineapples have been cut or divided into individual pieces in the form of annular slices or cored circular discs and the latter, superimposed upon each other, packed into containers of diameters substantially equal to the diameters which appeal to the canner. as well as to the ultimate consumer.

An object of my invention is the provision of a new method of cutting or slicing of trimmed pineapple cylinders, whereby the cylinder is divided lengthwise into longitudinal sections or segments or fingers rather than into flat transverse new method obtains in one section a portion of the pineapple from one end to the other, in other words, secures a better averageof succulence or quality. It is well-known that the succulence of pineapple meat is best about .its transverse center and not as good at or towards the two ends. When pineapple is served at the table, under the old method of cutting and packing, one person usually obtains a piece of one quality and another a piece of another quality.

Another object of my invention is the provision of a novel method and machine for packing solid or substantially solid products, such as pineapples, into containers, whereby and wherein prepared unsevered units of the product, of a size and shape corresponding to the size and shape of the container into which they are to be packed, are received and are cut into a plurality ofas sembled individual portions simultaneously or substantially so with the filling or insertion of the assembled units into containers.

Another object is the provision of such an improved machine wherein empty container bodies, closed at one end and open at the .other, and prepared or partiallyprepared product units are of the individual'slices. This manner of packing I have discovered a new manner of cuttingdiscs, whereby the ultimate. consumer under my fed into the machine in a continuous procession in timed relation with each other and wherein the product units are cut and the bodies and cut units meet in proper alignment at a packing station where the cut units are inserted into the aligned containers and after packing are discharged to be hermetically sealed in another machine.

Another object of my invention is the provision of such a machine which may include a trimmer mechanism for completing the preparation of the product unit for packing into containers.

Still another object is the provision of a high speed automatic and compact machine of comparatively simple construction adapted for carrying out my new method of cutting pineapple cylinders into longitudinal segments and simultaneous with the cutting or substantially so inserting these individual portions in an assembled unit, identical in shape with the original uncut unit, into containers, thereby performing a plu rality of operations in a single machine and thus saving time, labor and floor space..

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, disclose a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a fragmentary perspective view of one form of apparatus embodying myinvention andfor carrying out my new method.

Fig. 2 is an enlarged sectional view, with parts broken away, illustrating the trimming station, the cutting station and the inserting or packing station of the apparatus.

An example of one of many possible embodiments of my invention is illustrated in the drawings, the machine or apparatus shown therein being especially adapted for the cutting and packing of pineapples which have been previously prepared or partially prepared for division into smaller portions and insertion into cylindrical sheet metal containers by having the outer scaly skin or rind of the pineapple trimmed orpare'd away, with the scaly end portions left .untrimmed and having the center or core removed.

Such smoothly trimmed and cored pineapple cylinders P, with untrimmed ends e are fed into the illustrated machine by being placed either by hand or automatically upon an endless belt con'veyer H ,which takes over rollers l2, only one of which is shown, which revolve in a clockwise direction, thus carrying the placed pineapple toward the machine between spaced parallel guide rails l3 and I. when a pineapple P, and e foremost,.arriv.es at the machine end of conveyer belt II, it drops by gravity into an opening Ii of a transfer chute l6, which has attached to one of its inner walls l1, which depends at right angles to the plane of the horizontal plane of the "conveyer Ii, an L-shaped shelf or twister mentarily arrested and caused to turn from a' plate l8, upon which the falling pineapple strikes with th edge of itslower untrlmmed end. When it thus strikes the shelf l8, the pineapple is movertical position to a horizontal position and then drops to the bottom of the chute which is formed by a plate l9, set at a slightly descending angle to the walls II "or the chute and which .extends beyond a suhstantially horizontal chute extension 2| and terminates in an. upwardly curled portion 22, which forms a rounded stop, preventing further movement of the pineapple.

when a pineapple P arrives at the stop 22, it

is in axial alignment with a pocket 23 of a pine- ,apple conveying turret 20, and with a feed plunger {having a plunger head. 24, actuated in timed relation with the other operating parts of the ma-. giine in any suitable manner by a plunger rod 1 The turret 29 is journaledupon a shaft 26,

As previous intimated, this trimming operation may be performed before the pineapples are fed into the machine, in which case the knives 21 would be dispensed with and the end trimming station would be an idle station at which no operation is performed.

Another step rotation of theturret 23, brings the pocketed andcompletely trimmed pineapple to a cutting station, where it dwells long enough to permit a radial cutter plunger to function.

i It is this radial cutter plimger which subdivides or cuts the cored and trimmed pineapple cylinder into the novel uniform, longitudinal segments or fingers previously referred to. It comprises a cylindrical plunger shaft or core 28, which has keyed or welded or otherwise secured thereto, at equally spaced intervals, a plurality of radial cutting blades 29. The number of blades used depends upon the number of individual segments intowhich it is desired to divide the pine-- apple.

The shaft 28 has .sliding bearing in two depending bearing plates or brackets 3|, supported by any suitable frame part of the machine (not shown). Each bracket 3i is provided with a cir cular bearing aperture 32, from which radiate equaly spaced slots 33, which provide clearance for the blades 29 and correspond in number, po-

sitionand size to the latter. The shaft '28 and the apertures 32 are in axial alignment with the core of a pocketed pineapple when the latter reaches and dwells at the cutter station. At this time the cutter plunger is in its outer postion, as viewed in Fig. 1, with the inner end of the shaft 28 on a level with the inner wall of the right hand bracket 3i, so as to clear the turret 20. A suitably timed mechanism (not shown) now actuates the plunger shaft28, pushing the shaft and the blades 29 inwardly through the apertures 32 and slots 33 respectively, until the blades 29 are positioned centrally of theopposed brackets 3|. This action cuts the pineapple cylinder contained in the turret pocket 23 into a plurality of uniform segmental portions or'fingers 34. To provide clearance for the knife blades 29, during this cutting operation, the cylindrical wall of the pocket 23 is provided-with slots 35, corresponding in number and location. to the blades 29. As soon as the pineapple cylinder has been thus cut into individual but still assembled segments 34, the plunger rod 28 and the blades 29 are quickly withdrawn to again bring them to the position shown in Fig. 1.

The. turret isagain moved forward a step to bring the now out and still pocketed pineapple to the packing station, where the assembled cut portions are inserted into an aligned container A container C, having a cylindrical body closed at the bottom by a double seamed end closure and having an open top surrounded by a flange, is brought to the packing station by means of a can conveying turret 30 already briefly referred to. The turret 38 is journalled upon a shaft 3F,

having suitable bearings in frame parts of the machine (not shown) and is intermittently rotated with said shaft by any suitable power connection in a counterclockwise direction. It is .provided with a plurality of container receiving and holding pockets 31, whichin number correspond .with the pockets 23 in the pineapple turret 20. Empty, bottomed and flanged containers 0 are successively guided into the pockets 31 by means of chute guide plates 38, one of which terminates adjacent the periphery of the turret -39, and the other is continued substantially half' way around the periphery of the turret to provide a container retaining wall 39 or arcuate guide plate spaced from the turret periphery a sufiir, cient distance to permit travel of the pocketed containerbndies but. close enough to hold them in their pockets 31, as they are slid along the guide wall 39. Being synchronized with the movement of the turret 20 and other operating.

parts and having overlapping relationship:witli the turret 28, the turret 30 delivers an empty container C at the packing station at the same time as the turret 20 delivers a. cut pineapple. When turret pockets 23 and 31 thus meet, the

open end of the pocketed container C faces the left hand side of the pocket 23 and the container and pineapple are in exact axial alignmentwith each other. It is when both turrets are temporarily at rest that a packing plunger comes into action.

The packing plunger comprises a plunger head 4|, secured upon the end of a plunger shaft 42. Like the feed plunger head 24, the head 4| is of the same cylindrical shape as the pocket 23, but is of greater length since it has to travel further.

When the turret pockets 23 and 31 come to rest in axial alignment with each other and also in alignment with the head 4|, suitable mechanism (not shown) moves the head 4| inwardly as viewed in Fig. 1, in contact with the right hand end of the pineapple cylinder, through the pocket 23, pushing the cut pineapple in anassembled body clear of the pocket 23 and into the open end of the aligned container body C, the outer diameter of the pineapple substantially coincidingwith or being a trifle less than the inner diameter of the container body.

Further step rotation of the turrets 20 and 30 brings the combined can body and cut pineapple past the end of the retaining wall 39, and the filled can body drops out of the pocket 31 and onto a conveyor belt 43, which delivers the filled can to a suitable closing machine or other desired place.

It will thus be seen that I have provided a new method which broadly comprises feeding prepared, solid, severable products and empty containers in timed relation to each other, cutting the solid product into longitudinal smaller portions, and substantially simultaneously packing the still assembled cut portions in the identical shape of the uncut product into aligned containers and I have also provided one of a variety of machines which carries out my new method.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction, and arrangement of parts of the apparatus mentioned herein and in the steps and their order of accomplishment of the process described herein, without departing from the spirit and scope of the invention or sacrificing all ofits material advantages, the apparatus and process hereinbefore described being merely a preferred embodiment thereof.
