MACHINE FOR CUTTING CORKS.

SPECIFICATION forming part of Letters Patent No. 520,744, dated May 29, 1894. Application tiled May 15,1893. Serial No. 474,369- (No model) To all whom t may concern:

Be it known that I, FREDERICK C. TEUsLow, a citizen of the United States, and a resident of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Machines for Cutting Corks to Uniform Lengths, of which the following is a specification. Y

This invention has reference to an im proved machine for cutting corks of tapering shape to uniform lengths in a perfectly reliable and automatic manner, and the invention consists of a machine for cutting tapercorks to uniform lengths, which comprises an intermittently-,rotating feed-wheel having tapering holes corresponding to the size of the cork, a feed-tube by which the corks are successively fed to the holes of the disk, and a rotary cutter-disk by which the lower projecting ends of the corks are out off or trimmed to the required length. A spring arm presses on the upper end of the cork and holds it in position until the lower end is trimmed olf, upon which the trimmed-off cork is ejected, on the next motion of the feed-wheel by the action of an intermittently-operated lever so that the cork is dropped into a chute and conducted off, while the trimmed-off portion is conducted to a second chute arranged below the level of the feed-disk.

The invention has further certain details of construction, which will be fully described hereinafter and nally pointed out in the claims. Y

Referring to the drawings, 'Figure l, represents a vertical longitudinal section on line l-l,Eig. 2, of my improved machine for cutting corks to uniform lengths. Eig. 2, is a plan ot' my improved machine, partly in horizontal section on line 2 2, Fig. l, and Fig. 3, is a detail horizontal section on line 3-3 Fig. 1, showing the motion-transmitting gearwheels and the mechanism by which the feeddisk is intermittently operated and rested.

Similar letters of reference indicate corresponding parts. c

Referring to the drawings A represents the supporting frame of my improved machine for cutting corks to uniform lengths. The supporting frame A is provided with three pairs of neck and step-bearings which serve to support three vertical shafts S, S', S2, the shaft S carrying a cutter-disk B at its upper end, and a fast pulley p and a loose pulley p at its middle part. The fast pulley p receives rotary motion by a suitable belt (not shown in the drawings) in the ordinary manner. To the lower end of the cutter-shaft S is applied a fast pulley p2 which transmits rotary motion by a cross-belt b to a pulley p3 on the second or intermediate shaftS. The intermediate shaft S is provided with a mutilated pinion m which meshes at each rotation of the intermediate shaft S with a gear-wheel m on the third shaft S2, which is supported, like the cutter-shaft S and intermediate shaft S in a suitable step and neck-bearing of the supporting frame A and which carries a feed-disk C at its ripper end and in close proximity to the circumference of the cutter-disk B. The mutilated pinion m and the gear-wheel fm. impart intermittent rotary motion tothe shaft S2 and to the feedwheel O at each rotation of the driving shaft S and intermediate shaft S. The feed-wheel C is provided near its circumference with a number of equidistant and slightly-tapering holes d, into which are dropped successively the taper-corks that are to be cut or trimmed to uniform length. The corks are supplied from a suitable supply-hopper H which is supported on top of the main-frameA intoa box or hopper H and fed from the same by ka curved or inclined feed-tube H2which terminates above the feed-wheel into the holes (l of the same. The corks are dropped by the attendant one after the other into the feed-tube H? and dropped in regular succession into the holesof the feed-wheel O. Below the mutilated pinion m is arranged on the shaft S a cam m2 which serves to engage an anti-friction roller fr that is arranged on a lever L which is pivoted on one end to a bracket-arm n of the supporting-frame and connected at its opposite end by a helical spring n with a fixed arm n2 on the frame A, as shown clearly in Figs. 1 and 2. The lever L is provided with a fixed stop-tooth Z that serves to engage the teeth of the gear-wheel m', as soon as the latter has been moved for the required distance by the mutilated pinion m. While the mutilated pinion m intermeshes with the gearwheel m, the cam m2 is placed in contact with the anti-friction roller r, so as to press on the latter and move thereby the lever L against the tension of its spring n away from the gear-wheel on', so as to withdraw the stoptoothlfrom the teeth of the gear-wheel m. As the cam m2 is arranged so as to extend from the shaft S in a direction diametrically opposite to that of the mutilated pinion m, the action of the cam m2 on the lever L takes place simultaneously with the engagement of the teeth of the mutilated pinion m with the teeth of the gear-wheel m. As soon as the mutilated pinion m clears the teeth of the gear-wheel m', the lever L is also released from the cam m2 and the stop-tooth Z returned immediately by the action of the spring Z into engagement with the gear-wheel m', so that thesame is locked, firmly held in position and prevented from turning on its axis. The feed-wheel C is thereby also retained rmly in position, so that the tapering hole d which is then below the lower end of the feed-tube H2 is retained in position below the same for receiving a cork. If, for instance, the feed-wheel C is provided near its circumference with ten equidistant holes (l, the mutilated pinion m provided with six and the gear-wheel m with sixty teeth, then ten full rotations of the driving shaft S and intermediate shaft S are necessary to impart one entire rotation to the feed-wheel C. The entire rotation of the feed-wheel however, is made up from ten intermittent or step-bystep motions, which are imparted thereto by the mutilated pinion, said step-by-step motions being accurately dened by the stoptooth l, before described, so that one hole of the feed-wheel C after the other is placed in a reliable manner below the end of the feedtube H, and thereby the regular supply of corks to the holes of the feed-wheel from the feed-tube secured. The sharp edge of the rotating cutter-disk B moves in contact with the under side of the circumference of the feed-wheel C and extends sufficiently over the under side of the feed-disk that the lower proj ectin g ends of the corks are cut off or trimmed by the cutter-disk as they are successively fed by the feed-wheel toward the same. The corks are retained in the holes CZ of the feedwheel G by means of a spring-arm f which is attached to a cross-piece f of the supporting frame A above the feed-wheel C, as shown clearly in Fig. 1, said spring-arm pressing on the top of the corks as they are moved by the feed-wheel under the lower arm of the springarm f. The corks are thereby held firmly in position in the feed-wheel C, so that the lower projecting ends of the same are acted upon by the cutter-disk and trimmed or cut off to the required length. The lower cut-off end of the cork is dropped into a downwardly-inclined chute g, which is located below the feed-wheel C and conducted by the chute g into a suitable receptacle (not shown in the l drawings), while the trimmed cork is ejected `from its hole in the feed-wheel C after the next intermittent motion of the feed-wheel by an ejccting pin t' which is arranged for the distance of one hole d from the other back of the spring f at the rear-end of an ejecting lever fi', that is pivoted at its front-end tothe supporting-frame A and provided at an intermediate point with an anti-friction roller f2 that is engaged by a raised cam i3 attached to the upper end of theintermediate shaft S', as shown clearly in Figs. l and 2. The raised cam t actuates the ejecting lever '11 as soon as the feed wheel C is locked in fixed position by the engagement of the stop-toothZ with the gear-wheel m. The cam 3 raises the ejecting-lever i and forces thereby the ejecting-pin z' on its rear-end in upward direction out of the hole d so that the cork is removed from the same and dropped into an inclined chute g which is arranged above the first chute g onpa level or nearly so with the feedwheel, over which second chute the corks are conducted into a separate receptacle.

By the mechanism described, taper-corks of a certain size can be produced in a quick and automatic manner, as only one attendant is required for the proper supply of the corks to the feed-tube, all the rest being done automatically by the action of the machine.

Vhen taper-corks of greater or smaller diameter or of greater or smaller length are to be trimmed, the feed-wheel is replaced by one having holes of corresponding size and` of a thickness corresponding to the length of the cork to be produced. In this manner the machine can be used without any other change for cutting any size of taper-cork to the proper length, and thereby taper-corks of any required diameter and length supplied for the use of the different trades. v

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, of an intermittentlyrotating feed-wheel provided with tapering holes to which the corks are supplied, aspringarm adapted to bear on the upper ends ofthe corks, a rotating cutter-disk that laps over the under surface of the feed-wheel, so as to trim or cut olf the lower projecting ends ot' the corks, and an intermittently operated ejecting device, by which the cut-olf corks are ejected from the holes of the feed-wheel, substantially as set forth.

2. The combination, of an intermittentlyrotating feed-wheel having a number of taperin g holes for the corks, a spring-arm adapt ed to bear on the upper ends of the corks as they pass below the same, a rotary cutter-disk that is adapted to lap over the under surface of the feed-wheel, an intermittently-actuated ejecting device for removing the cut-olf or trimmed corks, and chutes arranged respectively below and on a level or nearly so with the feed wheel, so as to conduct off the trimmed-off ends and the taper-corks themselves, substantially as set forth.
