IIAKON SIGVART LARSEN, OF CHRISTIANIA, NORYVAY.

CORK-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,882, dated January 29, 1889.

Application filed June 21, 1888. Serial No. 277,785. (No model.) Patented in Norway August 27, 1887.

To all whom it'may concern:

Be it known that I, HAKON SIGVART LAR- SEN, a subject of the King of Norway, and a resident of Christiania, in the Kingdom of Norway, have invented certain new and useful Improvements in Cork-Cutting Machines, (for which I have received Letters Patent in Norway, dated August 27, 1887;) and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention consists in a cork cutting and finishing machine so constructed that the necessary hand-work consists only in placing the cork blocks in a certain position on the machine, while the operations of transporting said blocks to the cutting-tool, the accurate adjustment of them in front of said cuttingtool, and the rotating of them, whereby they are given their cylindrical form, are her formed by the automatic movements of the machine.

The machine comprises four groups or series of mechanismname]y, a cutting-tool, an apparatus for imparting a rotary motion to the cork blocks, an apparatus for catching the cork blocks and conveying them to the knife and the rotating mechanism, and'an apparatus for taking the cork blocks from the spot where they are deposited by the operator and carrying them to the proper position.

The im'ention will be understood on reference to the accompanying drawings, in which- Figure 1 represents a plan view of a machine constructed according to my invention. Fig. 2 is a vertical section taken in the line 0: a: of Fig. 1. Fig. 3 is a vertical section taken in the line y y of Fig. 1.

In Figs. 2 and 3 some of the parts are omitted or only shown in outline, so as not to interfere with the clearness of the drawings.

The cutting-tool consists of a circular knife, K, carried by one end of the main shaft A, which may be rotated by hand or by anysuitable motive power. From this shaft A the motion is transferred by abelt and pulleys to the shaft B, which is journaled on the top of the frame 0 of the machine. From the shaft B the several periodical movements are imparted by means of gearing and cam-wheels or the like to the different portions of the machine.

The transporting apparatus on which the cork blocks are placed is designated by the letter G. It consists of a ring, 1, of L-shaped cross-section, fitted in a guide, 2, mounted on the frame (1, Figs. 1 and 2. Said movable ring 1 is provided on the upper surface with pins 3, placed at such distancesapart as to admit a cork block between two of them. The

' periphery of the ring or wheel 1 is provided with a number of notches corresponding with the number of pins, and has an intermittent rotary motion imparted to it by means of a spring-pawl, 1, carried by one end of a lever, 5, which is pivoted at 6 and has its other end bearing against a cam-wheel, 7, on the shaft B, said lever being held in contact with the cam wheel by a spring arranged in any suitable manner. Vhen the cam-surface of the wheel 7 forces the short end of the lever outward, the pawl 4., carried by the other end, rotates the transporting-wheel a distance equal to the distance between two of the notches. The pawl at has its pivot 8 arranged in a slot, 9, in the end of the lever 5, and may be adjusted in either direction by means of the set-screws 10.

To the inner and outer surfaces of the guide 2 are attached two guard-plates, 11 and 12, which extend from the point where the cork blocks are placed on the wheel to the point where they are pushed into the catching apparatus or carrier-wheel H.

The cork blocks are pushed from the transporting-wheel into the catching-wheel H by means of a plate, 13, attached to one end of a rod,14:. The front end of this rod has a bearing in a guide, 15, and its other end is c011- nected to an arm or lever 16,by being passed through a sleeve or head, 17, pivoted at the upper end of said lever and held in place by means of two nuts which serve as adj ustingnuts, so that the plate 13 may be adjusted at a greater or less distance from the catchingwheel H. A spring, 18, surrounds the rod, with its ends bearing against the guide 15 and one of the nuts, respectively, and thus holds the plate 13 in proper position.

The movement of the plate 13 toward the catching-wheel is imparted by a rock-shaft, 21, whichhas at one end an arm, 20, bearing against a cam-wheel, 19, on the shaft B, the lever 16 being attached to the other end of said rock-shaft 21. lYhen the cam on. the cam-wheel strikes the arm 20, the movement is imparted to the rod 14.

During the movement of the plate 13 the cork blocks are held against said plate by means of a flat spring, 22, the detailed arrangement of which is hereinafter more particularly described.

The catching-wheel or carrier-wheel II is composed of two disks or wheels, 26 and 27 mounted on the same shaft, 25. The disk 26 contains the mechanism by means of which the cork blocks are caught, securely held, and carried up to the cutter, and the other disk, 27, contains a set of short spindles with flanges, against which the cork blocks are pressed by the disk 26, and which spindles, with chucks, are rotated by means of the turning apparatus F, arranged at the side of the wheel 27, which is periodically connected with the said spindles, so that the cork blocks are rotated in front of the cutter or knife K.

The disk 26 is provided with a series of holes near its periphery and parallel with the axis of rotation, and in each of these holes, which are drilled with an offset,is fitted from the inner side of the disk a short spindle, 28, with a flange, 20, provided with spurs, serving as a prong-chuck, and from the other side of the disk are inserted spring-boxes 3 The said spindles 28 are connected to the spring boxes by means of studs 31, screwed into the inner end of the spindles, and the heads of which are pressed toward the bottom of the spring-boxes by means of springs 32. As the spring-boxes are prevented from moving to the right, the spindles and chucks will have a tendency to move to the left. From the outside of the spring-boxes extend pins 33 through slots 34 in the periphery of the wheel 26, by means of which the boxes may be moved in their axial direction.

On the out-side end surface of the disk 26 are arranged arms 35, one for each sprii'lgbox, pivoted at one end, :30, with the other end long enough to reach in front of the holes in which the spring-boxes are inserted. The arms are held in place and guided by keepers 37, Figs. 1 and 2'.

Co-operating with the s]' ring-boxes and stopper-arms above mentioned are the lovers 38 and 235'), Fig. 2, carried by a shaft, 40, the lever 38 being about midway of the length of the shaft and the lever 39 at one end. The other end of the shaft 4-0 is provided with an arm, 41., to which is connecteda rod, =12, Figs. 1 and 3, actuated from the cam-wheel 43 on the shaft 13. The rod works in a guide, 44, and has an upright bend, (4.5, behind the camwheel, against which it is pressed by a spring, e5 The object of these devices is to catch and release the cork. blocks at the proper times. As will be seen in Fig. 2, the upper ends of the levers 38 and 39 terminate in front of two of the sprii1g-boxes-namely, the one belonging to the spindle, that catches the cork blocks, and the one next below, where the corks are turned. lVhen the levers move inward to the disk, they strike the ends of the spring-boxes and drive them inwardly. The result of this will be, as far as regards the arm 38, that the spring 32 will act upon the stud 31, pressing the spindle with the chuck into the cork block (just at that momentheld by the spring 22 and the plate 13) between the two disks, and instantaneously the stopper-arm will drop down and lock the springbox into the hole, so that it cannot again issue therefrom before the cork has been cut. It will then be released by the arm 39, which will press the spring-box at the time in front of the arm slightly inward. The arm 35, which was held by friction, will then drop down and allow the box to project out through the hole, thereby releasing the spring 32, and with it the spindle 2S and the cork. The cork is prevented from adhering to the spurs of the chucks by means of pin 33, working in the slot 3%. \Vhen the wheel moves the next step, this pin will. strike a wedge, 33, placed underneath the disk, and be forced with the box and the spindle to the right, so that the flange 29 will. come close to the side of the disk and the cork may drop down through a hole in the frame into a suit-able receptacle. To further insure that no cork shall adhere to the chucks, a rod, 33", Fig. 2,is connected to the same lever, 16, that pushes the blocks into the catching-wheel. 1V hen the said lever moves against the wheel, the rod 33" will also follow, and in case a cork should be hanging in the wheel push it down.

The disk 27 which is mounted on the same shaft with the disk 26, and accordingly moves together with it, has near its periphery in line with the spindles in disk 26 a series of short. spindles, 46, provided on the inn er side with prong-chucks and on the outside with coupling-clutches -l7, with which the couplingclutehes on the turningapparatus F periodically engage.

lVhen a cork block has been pushed between the two disks 20 and. 27, the machine is so timed that the lever 38 will press the spindle 28 into the cork, which will then be held between the two prong-chucks.

The object of the spring 22 is to accurately center the block between the chucks. The plate 13 being adjusted by the adj ustingnuts, the said spring will hold the blocks tightly up to the plate and keep them there until they are caught by the chucks. To release the spring, so that it shall not, when the block is taken upward by the wheel, snap outwardly, it is attached to one end of a pin, 23, boxed on the frame 0, which pin has 011 its other end an arm extending upward on the outside of the disk 27, where it rests against the coupling-clutches 417 of the spindles. At the moment the wheel moves a step forward the cou jiling-clutch will pass the end of the said arm and the spring will be released until the next clutch touches the arm.

The movement of the catching or carrier wheel H, which is periodical, and with such a long stop between each step that a cork may be turned and cut during this standstill, is imparted to it through the pivoted pawl 48, engaging with notches in the disk 26, the number of notches being the same as the number of spindles. The pawl l8 pivoted to the upper end of a rod, 40, working vertically in a guide, 50, on the frame (1. This rod is suspended in a hanger, 51, (the length of which may be adjusted by mea-nsof a right and left nut, as indicated in the drawings) on one end of a lever, 52, the other end of which bears against a cam-wheel, 53, on the shaft B,said lever imparting a vertical motion to the aforesaid pawl 48, in order to partially rotate the wheel lI, after which the lever falls of its own weight.

From the foregoing description it will easily be understood how the cork blocks one after another will be pushed into the (anu'ier-wheel H, taken up by this wheel, and carried forward till they reach the front of the cuttingtool or rotary knife K. Having reached to this position, they have to be rotated, so that the cutting-edge may give them their cylindrical form. This is performed by means of the turning apparatus 1*. This turning apparatus consists of a spindle, 54. resting in a stand, 55, on the frame, and on which is mounted a tooth-wheel, 50, with an, extended hub. The spindle axially movable in this hub, but must follow the tooth-wheel in its rotation, (a projection from the tooth-wheel working into an axial groove in the spindle, or vice versa.) The tooth-wheel is worked from the shaft 1 through the gears l) and E. The extemled hub rests on both sides in bearings in a stand on the frame, and the tooth-wheel is thereby prevented from following the spindle in its longitudinal movement. The spindle will, according to this, constantly revolve, while the longitinlinal movement is imparted to it periodically from the shaft 13 by means of a cam-wheel, 5S, acting on a lever, 59, pivoted on the frame, bearing near its mid-length against the cam-wheel and at its top provided with a fork that works in a groove orbetween two collars, 130, on the end of the spindle. By these means the spindle is moved oi'itwardly from the carrier-wheel toward the left hand side of the drawing, while it is held against the same by means of a spiral spring, ol,surrounding the spindle between the iflOEtl'illf 57 and a collar, (33, on the spindle. Themachine is so timed that when a cork has come in front of the knife the cam on the earn-wheel 58 will turn off from the lever 50, and accordingly the spiinlle will be taken inwardly by the spring (El, and the (:(mpling-clutch 03, mounted on the end of the spindle, will engage the coupling-clutch nL7 on the spindle in wheel 27, by which the cork block to be cut is held. As soon as the cork has been cut, (namely, rotated once,) the cam 58 will again take the spindle outwardly and the coupling-clutches will be disengaged, after which the carrier-wheel moves another step forward and the operation is repeated.

The machine has a circular knife, K, mounted on the main shaft A, the rotation of which knife greatly increases the effect of the cutting and facilitat s the work of the ma chine. To further facilitate the cutting, the knife is made so thin that it is necessary to mount it on a disk, (35.

To enable the machine to out different sizes of corks, the knife is made movable in the direction of its a This of course may be arranged in dif ent ways. As shown in the drawings,the main axle A is jo'urnaled in bearings or boxes carried by straps underneath the frame. One of these straps thc front one, (hi-is arrangtnl so that it may swing on one ofils bolts, of), while the other bolt, U7, lligs. 1 and 5' is insm'ted in a slot, (58, in the frame. When the strap (36 is swung either way, the shaft will be moved axially and the knife will be moved a greater or less distance from the center of the turning spin die. The boxes Tl are held to the straps by means of pins, so that they may swing laterally. That the knife also may be adjusted vertically, the forward strap is on one side provided with a set-screw, 70, by means of which and the bolt 7 the strap maybe raised or lowered.

In orderto keep the edge of the knife sharp, grinding-rollers may be attached to the frame, touching the sides of the knife, and thereby grinding the edge while rotating.
