Application-January 19, 1948. Serial No.3,124

The present invention relates to machines for seed-celling and slicing apples and similar fruits.

In the preparation of apples for cooking, canning and drying it is customary practice to first pare and core the apples.

chine for removal of theseeds and: seed cells and for quartering the'apples or dividing theminto lesser divisions. In conventional seed-celling and slicing machines, the apples are dropped over a rotating spindle and guided by their cored holes Then the apples are fed into a combined seed-celling. and slicing ma- 2 Claims. (01.146-40) to the slicing blades. Eachapple is seated against the slicing blades and is heldagainstrotation by these blades in a partiallysevered condition while the seed cells are being removed. The

'celling is effected by a rotary celling' knife which is secured to the rotating spindle and which operates approximately at the axial center .of the core of the apple. After celling, each apple is pushed-through the slicing blades; and thus the operation of the machine is completed.

The slicing blades only enter intov an apple prior to the seedolling operation but even this partial entrance slightly weakens'the apple and may result in the apple being split-prematurely under the slightly expanding pressure of the cell ing knife'at itscenter. 'This-is particularly 'the case if the appl'eliappens to beunusually soft and mellow. If the-apple'is split prematurely it is broken up into a lot'of unusable fragments.

One object of the present invention is to provide an improved slicing unit which will not only prevent an applefrom rotating-during ceiling but which will also hold the apple against the possi bility of fragments or pieces of the apple sliding outwardly longitudinally of the sliding blades before the apple is completely severed, so that tendency toward disintegratingexpansion of the apple is obviated, and the slicing operation may be accurately comp'leted'after decelling;

Another obj ectof the inventionis to provide an improved slicing fixture for amaehine of the character described in which the holding means is in the form of auxiliary slicing blades integral with or rigidly secured to the main slicing blades.

Other objects of the invention will beapparent hereinafter from the specification and from the recital of the appended claims.

In the drawings:

Fig. 1 is a fragmentary side view of a seedcelling and slicing machine constructed according to one embodiment of this invention;

,Fig. 2 is a central vertical section on a greatly enlarged scale of'the slicing spider or fixture of this machine;

' Fig. 3 is a view similar to Fig. 2: but showing a more complete assembly of the machine including the feedsp-indle and-seed-celling t me and showing an apple in the process of being celled; Fig. 4 is a detail sectional view taken on the line 4 a of Fig. 2 looking in the direction of the arrows; a

Fig. 5 is another central vertical sectional view of the slicing spider but taken in the plane of a different pair of blades from the plane of Fig. 2;

Fig. 6 is a plan view of the spider and its mounting;

Fig. 7 is a fragmentary plan view like Fig.6 but showing anapple in seed-celling position and in horizontal section;

Fig. 8 is a perspective view of one of the major knife blades and of its auxiliary blade; and

Fig. 9 is a perspective viewof one of the aux-- v iliary blades.

Referring now to the drawings by numerals of reference, i denotes the frame work of the machine which is supported by legs 2 (broken away). Supported on the'frame in a horizontal position is a mounting member 5 which is secured to the frame work by bolts 4' (Figs. 1 and 6). This mounting member has a. central opening and secured within this central opening by lugs 6 and v bolts 6' is a slicing spider 5. This spider is pro-, vided with two sets of slicing blades, the individual blades of eachset being denoted at 3 and 1, respectively. The blades 1 are more steeply inclined than the blades .3 and have their upper cutting surfaces above the cutting surfaces of the blades 3. All ofthe blades are arranged radially and are inclined downwardly; and their lower ends are fixed to a stationary sleeve 8.

H denotes the central feed spindle of the machine. This spindle is provided with an enlarged portion at Ill which is formed at its lower end with a shoulder 9 that rests upon the upper end of the sleeve 8. The spindle turns in the sleeve 8 and may be driven, for instance, bythe bevel gearing l3 from any suitable source of power according to conventional practice.

The enlarged portion It of the spindle has a flat portion I? to which is secured the rigid seed celling knife 14 (Figs. sand 7) by screws 15. This knife projects laterally from the spindle ll just above the blades 1 and is semi-circular in form. It is narrower at the top than at the bot; tom and is inclined slightly upwardly in a direction opposite to that of the rotation of the spindle as disclosed moreparticularly in copending application Serial No. 3,125 filed January 19, 1948-. Thus, when a cored apple slides down on the spindle, the knife ht makes an imperceptible track or channel in thecore opening thereof without further mutilation of the apple despite the continuous rotationjof the spindle.

4 l6 denotes a vertically swinging arm or beam having a fork or'bifurcation l! at its free end. This arm is adapted. toibe'oscillated up and down by conventional means. This arm is provided to insure correct positioning of the apple, which is to be celled and sliced, with reference to the ceiling knife. The cored apple drops by gravity below with the aid of deflectors 18. The same over the rotating celling knife l4 and upon the stroke places the apple Bin seed- -celling position, slicing knives l, and the said arm l6 and fork and so the operation of the machine proceeds.
