ALEXANDER IBOGDANFFY, OF NEW YORK, N. Y., ASSIGNOR TO INTERNATIONAL CORK COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

CORK-SHELL-GUTTING MACHINE.

To all whom it may concern:

Be it known that I, ALEXANDER BOG- DXNrrY, a subject of the King of Hungary, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cork-Shell-Gutting Machines, of which the following is a specification.

The present invention relates to an improved apparatus for cutting cork shells, or, as they are sometimes termed hollow corks.

One of the objects of the invention is to construct an improved apparatus for cutting cork shells, by means of which the work is accomplished automatically by one setting of the cork strips and by one operation of the machine.

Another object of the invention is to produce a machine that may be operated without employing skilled labor, and which is simple in construction and efficient in operation.

With these and other objects in view, which will more. fully appear as the nature of the invention is better understood, the same consists in the combination, arrange ment and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of a cork shell cutting machine constructed in accordance with the present invention; Fig. 2 is an end elevation thereof; Fig. 3 is a vertical longitudinal section through the combined cutters and stripper; Fig. 4 is a section taken on line 4-4 of Fig. 3; Fig. 5 is a section taken on line 55 of Fig. 3; and Fig. 6 is a vertical longitudinal section of a detail of construction,

In the drawings, the numeral 10 designates the bed frame of the machine, which rests on legs or standards 11, 11, carrying bearings 12, 12, in which the driving shaft 13- of the machine is journaled. Rotation may be imparted to this shaft in any suit- Specification of Letters Patent.

able manner, for instance by keying to the same a pulley 14, which is driven by means of a belt or otherwise. The bed frame 10 supports bearings 15, 16 and 17 of any suitable construction, in which are rotatably and reciprocatably arranged the cutting and stripping means of the machine. These cutting and stripping means are shown in detail in Figs. 3 to 5, inclusive, and comprise a tubular arbor 18, journaled in the bear ings 16 and 17, and provided in its front portion with inner screw threads 19, meshing with the outer threads 20 of a tubular cork cutter 21. l/Vithin the arbor 18 is slidably arranged a tubular member 22, the outer diameter of which is considerably smaller than the inner diameter of the arbor 18. To this tubular member is fastened a collar 23, which, together with the collar 24, that is attached to the arbor 18, holds the tubular member in concentrical relation relative to said arbor. The tubular member 22 is at its front portion provided with inner screw threads 25, which mesh with the outer screw threads 26 of a second tubular cork cutter 27. The cutter 21 serves to cut the exterior of the cork shells from the cork strips, while the cutter 27 cuts out the core from the shell. The arbor 18 is provided with a longitudinal slot 28, the walls of which are engaged by a pin 29, which is secured to the collar 23, whereby the tubular member 22 will rotate with said arbor, while its reciprocating movement is independent of that of said arbor.

For removing the finished product from the cutter, a tubular stripper 30 is slidably arranged between the cutters 21 and 27. To the inner end 31 of this cutter is attached a ring 32, which is adapted to bear against a shiftable sleeve 33, the latter being located between the arbor and the tubular member 22 and its cutter 27. Against this sleeve and the collar 23 bears a spring 34, which is coiled upon the tubular member 22. A spring 35, also coiled upon the tubular member 22, bears against the collar 24 and a ring 36, which latter is attached to the tubular member 22. This ring is provided with a peripheral groove 37, which is normally engaged by dogs 38, 38, arranged in slots 39, 39 in the arbor 18, and pivoted to the latter at 40, 40. Springs 41, 41 hold the noses 42, 42 of said dogs in engagement with the groove 37. When the noses 42 of the dogs 38 engage the groove 37 in the ring 36, the arbor 18 and the tubular member 22 will reciprocate together. It will appear hereinafter that, at certain points in the longitudinal movement of the two cutters, the same must reciprocate independently of each other. For this purpose it becomes necessary to disengage the dogs 38 from the groove 37 in the ring 36. To this end, a tubular extension 43 is arranged upon the bearing 17, the inner diameter of said extension being smaller than the distance between the outermost points of the free ends of the dogs 38. The dogs and grooved rings form a clutch, as it were.

From the foregoing it will be observed that the two cutters of the machine are made to rotate together in their bearings, and that they move back and forth together when the dogs 38 are engaged with the ring 36, and independently of each other when said parts are disengaged from each other. The stripper 30 reciprocates with the cutters in a manner which will be hereinafter described. The cutters 21 and 27, and so also the stripper 30, can be easily replaced by others as shells of different sizes are to be made.

Rotary motion is imparted to the cutting and stripping mechanism, for instance by means of a belt 44, running over a pulley 45, which is keyed or otherwise attached to the arbor 18, and over a pulley 46, mounted upon the driving shaft 13. It will be observed that, since the pulley 45 travels with the arbor 18, the height of the cylindrical surface of the pulley 46 must be at least as much as the width of the belt 44 plus the amount of the reciprocatory movement of the arbor 18 in one direction.

A back and forth movement is imparted to the cutting and stripping mechanism from a treadle 47, which is pivoted at 48 to a standard 49 and attached to or made integral with a bar 50, the upper end of which is fork-shaped, as clearly shown at 51. The prongs of the fork are provided with slots 52, in engagement with pins 53, 53, carried by a ring 54, which is loosely mounted upon the arbor 18 and held against longitudinal movement thereon by means of stop- rings 55, 55. Between the ring 54 and the rings 55 are arranged a plurality of balls 56, 56 for well known purposes. A spring 57, bearing against the treadle 47, tends to hold the same in its normal elevated position.

The cork strips are held in operative relation to the cutters and stripper upon a support 58, which is attached to a bracket 59, the latter being fastened to one of the standards 11 of the machine. The support 58 includes a vertical plate 60, carrying substantially horizontal lugs 61, provided with slots 62, which are engaged by screw threaded spindles 63 of a second vertical 65, whereby the plate 64 may be set relative to the plate 60 to a distance which corresponds substantially to the thickness of the V cork strip 66 to be worked upon. This cork strip rests upon a. base plate 67, which is attached to a lug 68, having a slot 69, engaged by a screw bolt 70, which is attached to the support 58, and meshes with a nut 71. By means of this arrangement, the base plate 67v can be raised or lowered as the corkstrips vary in heights. The plates 60 and 64 are provided with apertures 60 and 64, respectively, in the longitudinal axis of the arbor 18.

The cork strips are fed to the cutters by hand, and the finished product is adapted to fall into a chute 72, to be conducted into a receptacle 73 standing upon the floor. The cores of the shells pass through the tubular member 22 and drop into a chute 74, which is arranged at the outer end of the tubular member 22 and conducts the said cores into a. receptacle (not shown in the drawings).

The operation of the device is as follows: Normally the parts are in the position shown in Figs. 1 and 3 of the drawings, that is to say the stop 22, which is attached to the tubular member 22, bears against the bearing 15, and the two cutters are adapted to reciprocate together by reason of the dogs 38 being in engagement with the ring 36. In these positions, the springs 34 and 35 are compressed. The operatorplaces thecork strip upon the support and forces the treadle 47 downward in the direction of the arrow shown in Fig. 1 of the drawings. The rotary cutters and stripper are by this movement of the treadle caused to move toward the cork strip 66. The cutting edge of the cutter 27, being ahead of that of the cutter 21, will first enter the cork strip and perform the cutting operation as the rotating cutters and stripper are being advanced. As soon as the cutter 27 has cut the core of the cork shell, the free ends of the dogs 38 will be forced toward the longitudinal axis of the arbor 18 by the extension 43 of the bear ing 17, and be disengaged thereby from the ring 36. As soon as this takes place, the tension of the springs 35 and 34 will be released, whereby the spring 35 will force the tubular member 22 toward the bearing 15 so that its stop 22 will abut against said the spring 57 raises the same, and shifts the arbor 18 toward the bearing 15, when the springs 11 will lower the noses 42 of the dogs 38 into the groove 37 of the ring 36. In the meantime, however, the springs 34 and 35 are again compressed. As the spring 34 is being compressed, it stops the movement of the stripper 80 so that, as the arbor 18 is being moved toward the bearing 15, the cork shell will be pushed by the said stripper into the chute 72. The parts are then in positions to start again the cycle of operation now described. The operator advances then the cork strip upon the workholder a distance which is somewhat larger than the shell, places again his foot upon the treadle 4:7 and the play is repeated.
