MACHINE FOR CUTTING COB/KS.

To all whom 'it may concern:

Be it known that T, EDWARD CoNRoY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Machine for Cutting Corks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this speciiication.

Figure 1, is a top or birds eye view of the improved machine, with the circular cutter plate removed, and its outline represented by blue lines. Fig. 2, is a vertical transverse section of ditto at the line 1, 1, of Fig. l. Fig. 3, is a vertical longitudinal section of the same at the line 2, 2, of Fig. l. Fig. Li, represents the cam through whose agency the sliding plate is moved to the rough pieces of cork to be cut, and the machine is fed with the same. Fig. 5, is a section of the movable plate for sharpening the beveled cutting edges of the rotating cutter.

Similar letters in the figures refer to corresponding parts.

rThe nature of this invention and improvement consists in the employment of certain appliances, in connection with the rotary cutters, and sharpening device described in my cork cuttingmachine patented the 20th of April, 1858, as will enable the former to more effectually cut the corks, the latter to be more simply operated, and the corks to be automatically, and in a more simple and correct manner, brought and embraced between revolving heads while being cut, and discharged therefrom, than heretofore.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

The frame A, is made of a rectangular form of suitable size, strength and material to contain and support the several parts of the machine, and within this frame A, is arranged an upright sliding frame B, having horizontal right angled plates C, secured to its upper and lower ends, whose bent ends slide on horizontal guides D, fastened to the upper and lower transverse timbers of the frame A. Vithin the frame B, is arranged the cutter shaft E, which is slightly inclined from a vertical line to give the required taper to the cork being cut, and whose lower end is stepped in the end of an upright adjusting screw, passing through the lower beam of the frame B,

and by which" means the shaft E, can be raised or lowered to suit the desired thickness of the cork to be cut, the upper end of said shaft E, being inclosed in a sliding boX or plate p, provided with an adjusting screw s, for regulating the inclination of the shaft E, and consequently the taper of the cork. To the top of this sliding frame B, is secured one end of a curved bar F, the opposite end of which extends upward and outward from the side of the same, and is provided with dovetailed guides between which the sharpening device Gr, is arranged. This sharpening device consists of a plate G, whose end next the rotating cutter plate H, is tapered and made in the form of a segment of a circle, to correspond with the bevels and curve of the cutting edges of the rotating cutter plate H, from the lower surface of which projects downward a pin or stud I, against which the elastic end of a bent spring J, presses, to keep it against the curved edges of a cam plate K, secured to the top of the frame A, which serves to periodically bring the sharpening plate or device, in the proper relation to the edges of the cutters, during their revolutions, to sharpen the same.

Motion is communicated to the cutter shaft E, by means of a band L, passing around a band wheel L, secured on a horizontal transverse shaft M, on which is also secured a somewhat smaller band wheel or grooved pulley M, around which is passed a band M2, twisted and also passed around a grooved pulley MS, secured on a horizontal shaft N, turningin boxes secured to lugs, suspended from the frame. On this shaft is formed a screw or worm O, which meshes in gear with a pinion O', secured on the end of a longitudinal shaft O2, supported in boxes on the frame A, and extending from one side to the other, and having a cam O3, secured near its center, the segmental portions of which are of different diameters or radii, and joined by curved surfaces, for giving the required movement to the slide frame B. On the end of the horizontal shaft O2, opposite to that on which the pinion O', is secured, is attached a bevel cog wheel P, which meshes in gear with a similar sized bevel cog wheel P, secured on the lower end of an inclined shaft P2, turning in suitable boxes projecting from the side of the frame A, and having on its opposite or uppermost end a cam Q, the enlarged half of which is made in the form of a semi-circle, while the reduced portion is in the form of a segment of a circle concentric with the first portion, the peripheries of the two being joined by curved surfaces, one of which curves 1s more upright in its curve, in relation to the peripheries, than the other. On this shaft P2, immediately next the cam Q, is secured a bevel wheel B, on the bevel surface of which are formed cogs, extending nearly one half around the said bevel surface, the remaining portion being blank, in order that the said cogs shall, during the revolutions of the bevel wheel R, give a full revolution to a smaller bevel cog wheel S, with which it gears, at every revolution as it passes the same, and allow the said bevel cog wheel S, to remain in a state of rest during the remainder of its circuit, for the purpose hereinafter stated. This last mentioned bevel cog wheel S, is placed loosely on the end of a horizontal shaft T, turning in boxes on top of the front part of the frame A, being prevented from turning on said shaft T, by a cog or pin, which enters a longitudinal slot in the periphery of the Same which admits of the longitudinal movement of the shaft T, through the bevel cog wheel S, said shaft being surrounded by a spiral spring T', which is compressed between one of the boxes in which it rests, and a cog or pin on its periphery, so as to keep its outer rounded end always pressed in contact with the irregular periphery of the cam Q. The opposite end of this shaft T, is serrated, or provided with points, and immediately opposite, and on the same horizontal line, is secured to a slotted sliding plate U, a similar serrated or pointed hub U', which turns in a journal box rising from the end of the slotted plate U, and between which and t-he shaft T, the cork is held and revolved during the process of being cut.

Inside the upper front timber of the frame A, and at right angles to and above the plane of the upper surface of the same, is arranged a horizontal sliding plate V, moving in dovetail guides at its edges, and bent vertically at right angles at its front end, and having a horizontal dovetail slot on the front surface of the bent portion, in which is inserted and slides a slide W, greater in length than the width of the sliding plate V, and armed on its front surface with two or more sharp pins, which project the required distance therefrom to enable them to draw the uncut cork from t-he bottom of the trunk X, when inserted into the side of the same. This sliding plate V, is attached to the end of an obtuse angled lever Y, by a screw passing through a slot in the said end of the lever and entering the sliding plate V, which angular lever Y, is secured to the top of the frame A, by a fulcrum at its bent or angular part, and is provided with a spring Z, which presses against its front edge for the purpose of always keeping its end against the periphery of an irregular formed cam a, secured on the inclined shaft P2. One portion of this cam a, is in the form of a semi-circle, and from one of its terminations, there extends a curved eccentric surface, whose curve bisects a line tangential with a circle scribed from the center of the inclined shaft P2, and extending from a segmental surface of greater radius than the semi-circular portion, to which it is joined by a straight surface, tangential with a small circle also scribed from the center of the inclined shaft.

The operation of the machine is as follows llfotion being communicated to the horizontal driving shaft M, by any convenient power, a revolving motion is given the rotating cutters, and horizontal and inclined shafts O2, P2, respectively, through the bands L, M2, screws O, and cog wheel O', which causes the following eil'ects to be produced through the respective agencies of parts hereafter detailed in their regular order of action. We will suppose the several parts in the position represented in Fig. l, of the drawings, with a cork to be cut firmly embraced between the pointed surface of the hub U', and the corresponding surface of the arbor or shaft T, and the cam O3, in the relation to the friction roller .5, on the sliding frame B, which is constantly pressed against its periphery by the spiral spring c, represented. The cogs on the beveled surface of the wheel R, being meshed in gear with the bevel cog wheel S, or pinion, will turn the same, and the shaft or arbor T, on which it is attached, and with it the cork, in such a manner as to cause the same to be efectua-lly cut by the swift revolution of the cutters H, past its revolving surface, as described in my former patent before referred to in this specification. After this part of the process is performed, the semi-circular portions of the cams O3, a, and Q, will have respectively passed in their revolutions the friction roller Z), on the sliding frame B, end of the bent or angular lever Y, and rounded end of the arbor or shaft T, which have been respectively pressed against them by the springs c, Z, and T, and the sliding frame B, and rotating cutter plate H, attached thereto will be withdrawn from the cork, during the passage of the abrupt curved portion of the periphery of the cam O3, next the friction roller Z9, on the same, and simultaneous with this action, the shaft or arbor T, which, having made a revolution through the action of the bevel pinion S, on'its end, and the bevel cogs on the wheel Q, ceases to turn, and is then withdrawn from the cork by its end moving on to the smaller segmental portion of the. periphery of the cam Q, so as to disengage its serrated or pointed end from the said cork to allow of its ready discharge from the machine in a finished state. Immediately after this disengagement and discharge of the finished cork, the curved eccentric surface of the cam a, acts upon the bent or angular lever Y, and by forcing this end from it, vibrates the other, so as to slide the plate V, forward, and with it the sliding plate lV, on its front end, one of the ends of which latter (WV), is kept pressed beyond the sides of the sliding plate V, by a spring d, so as to bring the points on its front surface in the proper relation to the cork in the bottom of the upright trunk X, through which the rough corks are fed to the machine, and yet admit it to be slid with the same. The plate and points W, on its front surface are thus pressed forward by the eccentric portion of the cam a, as stated, and the points enter, and thus take hold of the lowest piece of cork in the upright trunk X, and after this eccentric portion of the cam a, passes the end of the angular lever Y, in its revolution, the said end of the lever Y, is allowed to again approach the shaft P2, and rest against the segmental portion of the periphery of the cam a, which causes the cork attached to the prongs or points on the plate to be drawn with the vibration of the opposite end of the lever Y, between the serrated pointed surfaces of the hub U', and shaft or arbor T, where it will remain until the said shaft or arbor is forced toward the hub U, so as to securely embrace the cork between the two, by the action of the abrupt surface, between the two segments of circles of the cam Q, the said slide W, moving longitudinally with the cork and holding it firmly until embraced as stated, after which the sliding plate V, and its attachments are slid from the cork and the points or prongs of the slide W, entirely withdrawn from the same, and the cogs on the beveled wheel R, during their revolution, again come into gear with the cog wheel or pinion S, and

the abrupt portion of the cam, acts on the friction roller b, and presses the sliding frame B, and the rotating cutter H, turning on the same forward, and in this manner cuts another cork. Tn this manner the operation is continued at each revolution of the arbor or shaft T, at whose end it is held, and the rotating cutter H, being successively sharpened by the sharpening device being periodically brought into contact with them, as before stated, at the finishing of each cork.

Many of the working parts of this machine may be duplicated if desired, so as to cause a cork to be cut at both sides of the machine, and in this manner double the number of corks can be cut.

lVhat I claim as new and desire to secure by Letters Patent, is,

l. The combination and arrangement of the sliding plate V, sliding plate and spring or pointers W, in front of the same, vibrating angular lever Y, and cams a, a, on inclined revolving shaft P2, partly cogged wheel l, and spring arbor or shaft T, for

.placing and securing the rough pieces of corks to be cut between the pointed end of the said arbor or shaft T, and correspondingly pointed revolving hub U, the whole being constructed and operating substantially as before described.

2. T claim the combination of the cani K, secured to the top of the frame A, and curved spring J, with the sharpening device G, and rotating cutter plate H, for sharpening the cutters after they have cut the cork, and are in the act of being again withdrawn and moved toward the arbor or shaft T, as described.

3. I also claim the combination of the cani O3, and friction roller Z), with the sliding frame B, as set forth.
