CORER.

Application filed April 8, 1922. Serial No. 550,643.

To all whom it may concern.

Be it known that 1, WILLIAM B. F ENN, a citizen of the United States, residin at Port Washington, county of Nassau, btate of New York, have made a certain new and useful Invention in Corers, of which the following is a specification.

This invention is directed to corers, or, in other words, to a device for extracting the core from fruit such as apples; vegetables, such as tomatoes, etc.

The object of the invention is to provide a corer which is simple in construction, eflicient in operation and economical of manufacture.

A further object of the invention is to provide corer edges opposite in action and mechanically operated.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all'as will be more fully hereinafter set forth, as shown in the accompanying drawings and finally pointed out in the appended claims.

Referring to the drawings: I

Figure 1 is a top plan view of a corer embodying my invention, the jaws of the corer being open.

Fig. 2 is a similar view showing the jaws of the corer closed.

Fig. 3 is a sectional view taken on the line 33, Fig. 1, looking in the direction of the arrows.

Fig. 4 is a sectional view taken on the line 44, Fig. 2, looking in the direction of the arrows.

Fig. 5 is a view similar to Figs. 1 and 2 showing the jaws of the corer partially closed.

Fig. 6 is a sectional view taken on the line 6-6, Fig. 5, looking in the direction of the arrows.

Fig. 7 is a detail view in elevation of the corer jaws showing the same in open position.

Fig. 8 is an elevation showing a conveyor suitable for carrying and operating a plurality of my corers.

Fig. 9 is a plan view showing means for closing my corer.

Fig, 10 is a viewin elevation of the corer showing the jaws closed, or the position assumed after having passed the closing detent shown in Fig. 9.

The same part is designated by the same reference character wherever it occurs throughout the several views.

While I have shown and will now describe my invention and mechanically actuated coring devices particularly adapted for use for extracting the cores from tomatoes, I do not desire to be limited or restricted in this respect as the features of the invention therein contained may readily 'be utilized for extracting cores from other vegetables. fruits, etc, and mechanical actuation thereof, while eficient, is not necessitated.

In the arrangement shown, however, I show a corer structure which is designed to be used in connection with a machine for removing the skins from tomatoes, and wherein the corer structure consists of a base 1 having secured thereto guide plates 2 which guide plates are secured in any suitable manner, for example, by means of screws 3. The guide plates are placed on opposite sides of the base 1; each of them is provided with one or more downwardly extendin pins 4. which, in the form shown, are utilized to seat in sprocket chains 101 employed for moving the corer structure. Modifications in this detail, however, will readily occur to those skilled in the art without departing from the spirit and scope of my invention.

The base plate 1 is provided with a substantially circular orifice through the approximate center thereof, and secured to the plate 1 on opposite sides thereof, for example, by means of screws 5 is a pair of plates 6 and 7. (See Fig. 6). The lower plate 7 extends into the opening or orifice in the base plate 1 and is provided with a flange 8 which forms a pivotal support for the jaw and members 9 and 10, which will be more fully hereinafter described.

The jaw members are each pivotally mounted on the respective flange portions 8 of the plates 7. The other plate 6 which is held clamped to plate 7 by the screw 5 is.

likewise provided with a flange portion 11 having an extending lip 12' The flange portion 7 and the lip 12 form a cutting annular recess between the lip 12 and the top of the base plate 1, it being understood that the plate 7 is countersunk relative to the base plate 1 at the edge of the orifice or opening through the center of the base plate 1. Held by the plate 6 with its flange and lip 11, 12, respectively, for rotary movement in the annular space above described. is

what I will term the actuating ring 13. This ring contains a projection in the form of a pawl illustrated at 14, which, when engaged, serves to rotate the ring in one direction, in the form shown counter clockwise, and substantially opposite thereto two rounded projections 15 and 16 which, when rotated, serve to rotate the ring in the opposite direction, in the form shown clockwise. The ring is also provided with two downwardly projecting lugs 17 and 18 arranged diametrically opposite each other, which lugs carry

rigidlytherewith pins

19 and 20. The jaws, as above noted, consist of substantially semi-cylindrical members 9 and 10, the upper ends thereof being cut away and the re spective members being pivoted at the ap proximate end of their cut-away portion so that when the j a-ws are rocked so that the upper ends thereof move towards each other, the contacting edges form a straight line as illustrated in Fig, 2; whereas, the opposite ends thereof are at a maximum distance apart. When the jaws are in cutting contact with each other, i. e., the cut-away portions, it is understood that these portions are sharp-edged to form in effect clippers.

Each of the jaws 9 and 10 is provided with a cam groove 21. All of the jaws 9 and 10 are similarly constructed with the cam groove 21 extending in an upwardly direction throughout the width of the aw,

i but it will be readily apparent that when for closing and opening my corer.

two jaws'are placed opposite each other the cam grooves 21 extend in opposed directions relative to each other. The

pins

19 and 20 which form part of the rotatable ring 13 extend through the cam grooves 21 respectively of the jaw members 9 and 10 so that when the actuating ring is rotated in one direction, due to the cam action effect by the grooves 21 and the

pins

19 and 20, the jaws are opened, and vice versa.

The corers may be mounted and operated in any convenient or suitable manner. As a practical illustration, however, I have elected to move a number of covers on a conveyor or chain 101, which is carried on pulleys 102 which are driven by power, as a motor (not shown). A frame or

standard comprising uprights

103 and 103 and a bridging 'membrlO-i affords proper supportfor the conveyor. The pulleys may be provided with sprockets'105 for each side of the conveyor chain.

At a suitable positionon the frame and bridge members I provide operating detents The closing detent finger 106 is carried on a fixhim 107 for engaging lugs 15 and 16 as the corer passes the detent finger. This fixture may be secured to the bridge at any desired place where it is intended to close the corer and thus remove the core from fruit 10.8 which is snbjected to the operationby being placed on the open corer as at a position, say X.

For opening the corer a detent similar to the closing "detent is provided and this may likewise be placed at any desired position beyond .a point Y where the fruit has been removed. Preferably, though not necessarily, I place .the opening detent finger on the standard 103. As the corer passes this detent at a position, say M, the detent finger engages the opening lug 14: for rocking the actuating ring 13 to open the corer jaws 9 and 10.

The operation of the corer will now be briefly described. The corer is normally maintained in the position with the jaws open which convert the cutters or jaws into substantially a cylinder, in plan view, as seen in Fig. 1. The tomato or other article to be cored is impinged upon the jaws 9 and 10 so that the same encompass the core. It will be readily apparent that this will be facilitated when the edges of the jaws 9 and 10 are knife-edged, as above described. The corer assembly, in the form selected for illustration and which is being described, is then moved by the chain 101 which engages the pins 4, as described, until it is desired to cut out the core of the article, at which time the actuating ring 13 is rotated mechanically or otherwise by means of the lugs 15, 16 to the position shown in Figs. 2 and 4: whereby the core is cut out and allowed to drop through the open and extended bottoms of thejaw members 9 and 10. This operation does not, however, release the article impinged upon the jaw members 9 and 10 which is held thereto, the holes through side walls of the jaw members assisting to hold the article thereon. When it is desired to again open the jaws the lug llis mechanically or otherwise engaged to rotate the actuating ring in a counterclockwise direction back to the position shown in Fig. 1.

It might be advisable to remove the artiole being cored from the corer while the jaws are in a closed position, to ensure perfeet extraction of the core.

Many modifications and changes in de tails will readily occur to those skilled in the art without departing from the spirit and scope of my invention as defined in the claims, but having now set forth the objects and nature of my invention and having shown and described a structure embodying the principles thereof, what I claim as "new and useful and of my own invention, and desire to secure by Letters Patent is:
