FRUIT-SLICER.

To all 'whom it may vconcer/n.:

Be it known that I, FRED G. Mownn, a

citizen of the United States, and resident of Antrim, county of Hillsboro, State of New Hampshire, have invented an Improvement in Fruit-Slicers, of which the following description, in connection with the accom panying drawing, is a specification, like letters on the drawing representing like parts.

This invention relates to machines -t'or slicing fruit, and especially to machines for slicing apples, although certain features of the invention can be used in machines for slicing other kinds of fruit than apples.

Most apple-slicing machines now on the market are so arranged that one apple at a time is fed across the slicing knives by the pushers or sweeps. Such machines can slice the apples only as tast as the individual apples can be handled.

One of the objects of my invent-ion is to increase materially the capacity of appleslicing machines by providing a mechanism which Jfeeds a plurality of apples simultaneously to the sweeps and which feeds a plurality of apples simultaneously over the slicing knives. The machine herein illus trated is arranged to take four apples at a time and feed said four apples simultaneously over the slicing knives by means of a single sweep, and said machine thus has substantially tour times the capacity of slicing machines as ordinarily made. My invention, however, is not limited to making the machine of such a capacity that each sweep will operate fourapples simultaneously, as the number of apples controlled by Specicaton of Letters Patent.

consequently the thickness of the slices into which the apples are cut can be varied.

Other features of my invention will be "more fully hereinafter described and then pointed out in the appended claims.

In the drawings wherein I have illustrated one embodiment of my invention,

,is a detail view of one of the pushers or sweeps.

In the present embodiment of my invention the slicing knives and the pushers or sweeps for feeding the apples thereover are supported on a suitable frame 3 which may -have any appropriate construction adapted to support these parts.

.are of the shape shown in Fig. 9. Each link comprises the base piece 9 and the inclined arm l0 to which the sweep 6 is secured in any suitable way. The base pieces 9 are pivotally connected together so as to form an endless chain and there is such an end* less chain made up of such links at each side of the machine, each endless chain running over the two drums 7 and 8. The sweeps 6 connect the inclined arms of one endless chain to those of the other. The drums 7 and 8 may be rotated 1n any suitable way to give the sweeps the necessary motion to feed the apples across the slicing knives, and as herein shown, the drum 7 has fast to the shaft thereof a gear 11 which meshes with andis driven by a pinion 12 on a driving shaft 13, said driving shaft having thereon a handle or a belt pulley 1/1 by means of which it may be operated. These sweeps or pushers 6 pass above the slicing knives 1, as best seen in Fig. 3, and situated in front of the slicing knives is an apple-positioning floor 14 which has a particular construction which will be more fully hereinafter described. Said ioor and slicing knives are situated underneath the lower run of the endless chain arrangement. Underneath the upper run thereof is arranged a floor or platform 15 which forms with the pushers 6 apple-receiving compartments 16 into which apples are deposited by means of an appledelivery drum 17. This floor 15 is preferably provided with the curved extension 84 which encircles the shaft 85 of the drum 8 and terminates immediately above the lower run of the endless chain arrangement. The drum 8 is inclosed in a casing 83, and said casing and the curved extension 8a serve to prevent the apples from rolling out from the compartments formed between the sweeps as said sweeps are passing around the drum 8. The floor 15 is also preferably provided with side walls 8O and the positioning fioor 14 with other side walls 81 which prevent the apples from rolling laterally out from the compartment-s.

The apples which are delivered to the compartments 16 are carried along by the sweeps as the latter move in the direct-ion of the arrows Fig. 3 until said apples are carried around the drum 8 and on to the appl'ei positioning floor 111 where they are positioned. on end, as will be presently described, and from which they are fed to the slicing knives by the sweeps. The apple-delivering drum 17 is provided with a plurality of apple-receiving pockets 18 and it rotates adjacent to a hopper or chute 19 into which apples may be fed from any suitable source. The apple-delivering drum is rot-ated in the direction of the arrow shown in Fig. 3, and as it rotates, apples from the chute 19 gravitate into the pockets 18, and said apples are delivered from the pockets into the compartments 16, as plainly seen in Fig. 8. The

drum 17 is rotated in timed relation with the movement of the sweeps so that as each compartment 16 comes into proper position relative to the drum, the apple or apples in one of the pockets 18 are delivered into said compartment 16. For thus rotating the drum 17, the latter is provided with a gear 2O which meshes with and is driven by one of the chains to which one end of each sweep is connected. For this purpose the portions 9 of said chain are in the form of a rack which meshes with the teeth of the gear 20, as seen in Figs. 3 and 9. This rack may be formed by making the portions 9 of the chain with recesses 21 to fit the teeth of the gear 20.

As stated above, one of the features of my invention is to provide a slicing machine which is to take a plurality of apples at a time and pass them simultaneously across the slicing knives, thus increasing materially the capacity of the machine. In the embodiment of the invention shown in the drawings the length of the sweeps and of the compartments between said sweeps is long enough to accommodate four large apples and each apple-receiving pocket in the drum 17 is also long enough to receive four large apples side by side. As the machine operates, therefore, each pocket 18 receives the required number of apples to till said pocket andl utilize the full capacity of the knives. These apples kare delivered simultaneously into a compartment 16 in front of one of the sweeps and are carried by said sweep around over the positioning floor 14 where they are positioned on end and are then carried simultaneously across the slicing knives, and are simultaneously sliced. The result is that with my improved machine, four apples are being treated simultaneously and thus the capacity of the machine is increased to four times that of an ordinary slicing machine. In order that the four apples received in each pocket 18 and in each compartment 16 will not pile on top of each other yand thus interfere with the operation of the machine, I have provided a construction for maintaining these apples separated and in proper positio-n relative to each other while in the pocket and while in the compartment.

The pockets 18 are. each shown as provided with the central partition 22 which divides the pocket into two smaller compartments, each of which is adapted to receive two apples. There is almost no likelihood of two apples piling up on each other' and interfering with the operation of the machine, while three or four apples delivered into the same compartment may do so. By thus dividing said pocket 18 into small compartments each adapted to receive two apples, the four apples in each pocket are separated into pairs. This separation of the apples is preserved while they are in the compartments 16 and while they are being carried over the positioning floor and the slicing knives. For this purpose the platform 15 is provided with a separating rib Q/vl, see Fig. 8, which maintains the apples separated into pairs while they are being carried over said platform, and similarly the positioning floor 14 is pro-vided with. the central rib or partition 9.5, see Fig. 9, which maintains the separation of the apples into pairs as they are passing over the positioning floor. Each sweep is provided ateach edge with a recess or notch 26 in which the separat- ing partitions 24 and 25 are received.

Apples are universally cored and pared before they are sliced and in slicing them, it is desirable that they should be so positioned lthat the slices will be cut at right angles to the aperture formed by the removal of the core. The pared and cored apples are usually flatat their ends, that is, at the ends of the core opening, and my improved positioning loor is arranged so that as the apples are passed thereover by the operat-ion of the sweeps they are positioned on their `flat ends with the result that when they pass over the slicing knives, the slices are cut at right angles to the aperture formed by the removal of the core and are in the form of rings. The proper positioning of the apples to secure this result is attained by the coperat-ion of the sweeps and the positioning floor 14. These elements are so arranged that as the apples are moved over the positioning oor each apple will be turned about both a horizontal and a vertical axis, and by this peculiar motion, it will invariably be brought onto its flattened end before the slicing knives are reached. It will be noted that the sweeps are arranged at an inclination to the floor, and by reason of this position, they have engagement with the apples slightly above the horizontal axis. The positioning floor is also arranged so that itfwill tend to give the apple a turning movement about a vertical axis, and this is secured by making the Hoor with grooves which extend in a direction at an angle to the direction of movement of the sweeps. The grooves are comparatively near together so that when the apple finally comes onto its attened end the flattened portion of the apple will span two or more grooves. These grooves may have various shapes without departing from t-he invention, and I have herein shown them as being rounded in cross section and the ribs between the grooves are also shown as rounded. This makes a corrugated floor which secures the desired end. As the apples pass over the fioor, the inclined or diagonal direction of the grooves and ribs cause the apple to tend to turn about an axis perpendicular to the floor, while the action of the sweeps tends to cause the apple to turn about a horizontal axis parallel to the sweep. The combined operations o-f the sweep and the positioning licor roll the apples in such a way that each apple invariably comes vinto position with its flattened end resting on the floor, and when this occurs the apple will maintain such position because the flat surface thereof extends from one rib to another. I have found that best results can be secured by giving the grooves or corrugations a zig-zag shape, as shown in Fig. fi, that is, by making each groove or corrugation inclined in first one direction and then in the other because with this construction the apples will be rolled first in one direction and then in another, depending on the direction of the grooves or corrugations. I find it convenient to provide these zig-zag corrugations in the floor by making the floor from a plurality of separate blocks 27 which are suitably supported in the frame 3. Each block has its upper surface corrugated and the corrugations of adjacent blocks extend in opposite directions, as plainly seen in F ig. 4:, thus giving co-rrugatio-ns of the zig-zag shape. As the apples are passed over the slicing knives, the slices into which said apples are out fall into and are collected in a suitable hopper 28 situated beneath the slicing knives. The thickness to which the slices are cut depends upon t-he angular position of the slicing knives. It is customary to firmly fix the slicing knives in the desired angular position, in which case the slices can be out of only one thickness.

I have provided a slicing device which is adapted fo-r cutting slices of any desired thickness and this is provided for in my present invention by arranging the slicing knives so that the angular position thereof can be readily adjusted, and in securing such adjustment I have provided a construction wherein the adjustment may be effected without moving the cutting edges of the blades o-ut of the plane in which they operate. As herein shown, each slicing knife is supported on a plurality of rockers 30 which are pivotally mounted on the frame 5. Fig. 6 shows one convenient form of rocker, and it is provided with the top surface 72 to which the knife may be screwed, and it is also provided with a trunnion 32 by which it may be pivotally mounted in the sides 31 of the frame. I have herein shown three such rockers for each knife, one rocker being situated at each end of the knife and the other rocker at the central portion of the knife. All of the rockers on each side of the frame and also all of the rockers situated centrally of the frame are pivotally connected together, and this may conveniently be done by providing each rocker with a trunnion 7 i which hais pivotal connection with a bar o-r link 33, there being one such bar for each series of rockers. Each bar 33 is shown as having a slot 34 in the end thereof in which slot is received a cam 37 mounted on a rock-shaft 36 that extends across the frame 5 and is jo-urnaled therein. This rock-shaft has the handle 38 thereon by which it may be turned. The turning of the rock-shaft and the consequent turning of the cams in the slots will obviously move the links 33 backward or forward, and such motion will give sutlicient rocking movement to the rockers to change the angular position of the knives, as will be obvious. It will be noted that the cutting edge of each blade is situated over the axis of the' rocker supporting said blade. `With this construction the swinging of the rockers does not carry the cutting edges of the blades up and down or out of the plane in which they operate, for the changing of the angular position is secured by raising and lowering the back edges of the blades rather than the cutting edges thereof. The slots 8st and cams 37 operate to hold the knives lirmly in any adjusted position, but the angular position of said knives can be readily changed by simply turning the lever 38 slightly. This provides a very simple means for controlling the thickness of the slices.

In order to prevent the apples from becoming clogged in the chute 19, I have pr0- vided said chute with a false bottom 39 which is adapted to be moved longitudinally of the chute. Said false bottom is provided at its lower end with a roll a0 which rests on the drum 17 centrally thereof and which moves against the edge of the partitions 22 as the drum rotates. These partitions preferably have flat ends so that as the drum rotates the false bottom 39 is vibrated slightly, such vibration being sutlicient to prevent the apples from becoming clogged.

In order to prevent the apples from being discharged from the pockets 18 before the drum 17 is turned into a proper position to deliver the apples to the compartments 16, I propose to form the pockets 18 with parallel sides, as shown. By means of this construction the apples in any pocket will be held therein until said pocket is turned below the horizontal position and there will then be no danger of the apples being discharged from the pockets before the compartments 1G are suitably positioned.
