BARREL-HEAD-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 493,064.,dated March 7, 1893.

Application filed June 9, 1891. Serial No. 395.641- (No model.)

To all whom it may concern.-

Be it known that I, J AMES A. CAMPBELL, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Barrel-Head-Cutting Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in barrel head cutting machines, and cousistsz first, of a machine having mechanism substantially as described for automatically feeding, stopping and cutting the boards for the purpose set forth.

It further consists of novel mechanism for automatically withdrawing the board from beneath the cutting mechanism when the cutting has been elfected.

It further consists of novel cutting mechvanism.

Similar letters of reference indicate corresponding parts in the several figures.

able in the guides 0, formed in the sides of the upper side bars D. The said table is provided with cross bars E, which carry the spring dogs F, each of the latter having a pivoted pawl G provided with upper and lower teeth G and G see Fig. 9, the said teeth G being adapted to bite or grip the board when the table is moved in one direction, so as to feed the same to the cutters, but also adapted to be raised from the board by the contact of the tooth GXX with the board, so as to freely pass over the same when the table is moved in the opposite direction or away from the cutters, so that the said tooth Gr is not worn by being rubbed or dragged over the board.

Secured to suitable supports on the sides of the frameA, and at or near the portion thereof on which the table B operates, are the cross bars H, which are also provided with the dogs H similar to the dogs F, for preventing the return of the boards, on the backward movement of the table. Secured to the sides and extending above the frame A are the uprights J having the connectingcross bars K and K, in which is journaled the hollow shaft or collar L, having connected with its lower end the circular head M, to the rim of which are secured cutting tools of the device. Within the hollow shaft L is a stem or shaft N, the upper end of which is secured to the lever P, pivoted at one end toone of the uprights J, and carrying on its other end a weight Q. The other end of the shaft N is connected with a clamping head or disk R having pins thereon for holding the board in place during the cutting operation.

To the shaft L is secured a lever L which is pivoted at one end to one of the uprights J, and at its other end carries a weight T. A vertical bar U is pivotedatits lower end to the lever L, and is provided at its upper end with a slot U in which is located the stud V, which connects it with the lever P. Keepers S secured to an upright J limit the movements of said levers P and L. The lower keeper S is provided with a screw S for adjusting the play of the lever L therein.

Connected with the base of the frame A and the lower ends of the uprights J is a cross bar T in which is journaled a hollow shaft or collar W having at its upper end a circular head X, the rim of which carries the lower cutting tools of the machine. Alever Y pivoted to a suitable support Z has its forked or bifurcated end pivotally connected to the shaft W by means of the studs A which fit in a groove B on said tube, so that said shaft may be freely rotated without moving said lever, while at the same time the lever which carries the weight 0' may lower said shaft without affecting its rotation.

WVithin the shaft V is a stem D having at its upper end a clamping head or disk E, which with the head Rholds the board, which is being cut, in fixed position during the cutting operation.

The rims of the cutter heads M and X are each provided with the cutters F, G, and H. The advance cutter F which projects at substantially a right angle from the rim, is adapted to cut or saw out a circular head from the board held by the clamping disks; the next cutter, G, is of the form of connected gouges or chisels, inclined to the axis of the cutter head so as to form a beveled edge or rim on the head, while the cutter 1-1 is of the character of a plane and inclined so as to smooth the beveled edge.

To reciprocate the table B so as to feed the boards to the cutters the following mechanism is employed. A driving shaft M isjournaled in a suitable portion of the frame A, and carries the loose and fast pulleys N and P, and a pinion Q, the latter meshing with a gear wheel R on a shaft S journaled in the frame A. On the shaft. 5 is a crank arm T which has a pitman connection U with one of the arms X, rigidly secured to a rock shaft W, journaled in the lower end of the frame A, said arms X,X being pivotally connected by the bars Y, Y, with the table B. The connection of the pitman U with the arm X, is by means of a block U pivoted to said arm and adapted to move lengthwise on said pitnian, being held in place thereon by means of the bolts or stops W which move in the blocks Y secured to the pitman, the said bolts having the coiled springs Z thereon, and bearing against the said blocks and the heads of the bolts. The nuts V on the threaded ends of the bolts control the play of the springs.

To rotate the cutter heads M and X, the shafts or collars L and XV are provided with the pulleys A and B respectively, which receive motion by means of bands or belts thereon. connected with any suitable motor. The cutter head X has a slight rising and falling motion imparted to it by means of the link A, the lever B pivoted to a suitable portion of the frame of the machine and having a roller G which is engaged by a cam D on the shaft S.

Connected with the lever L is an arm C of a lever D which is pivoted to the frame A, at- D and carries an anti-friction roller E at one end, the latter being in contact with a cam F on the shaft S, whereby as said shaft is rotated the lever is operated so that the end of thelever D connected with the arm C is raised and thereby the leverL and thus the shaft L and cutter head M with its cutters.

A shaft G carrying a boring tool at its lower end for forming holes or recesses in the board for a purpose hereinafter explained, is journaled at one side and in advance of the cutting mechanism, in the arms H extending from the cross bar K and has its lower end guided in an arm of a block J? secured on the frame of the machine and is provided with an operating pulley G thereon. A lever K pivotally connected to the shaft G and to a pivoted attachment L of the arm H and carrying a Weight M bears upon the upper end of the bar U. In rear of the cutting mechanism, and in line with the boring shaft G is an oscillating dog N carrying a stud I adapted to enter the hole or recess made by the boring tool in the board. The pivoted stud or shaft Q of the dog N has a rigid arm R which is connected by the wire or rod S with a lever T mounted on the arm U of the frame A, and carrying on its lower end an anti-friction roller V engaging with a cam W on the shaft S.

To limit the travel of the table B when required, the frameAis provided withaspringcontrolled dog X adapted to engage a stud or projection Y on the side of the said table and provided with a handle X on its outer side for manipulating the same.

On the rear end of the frame Aand at a little farther distance from the boring shaft than the length of the boards operated on, are the studded wheels A mounted on the shaft B which is journaled in bearings A connected with the rotary shaft 0 and operated by the latter by means of the meshing gear wheels L and E the shaft 0 receiving power from any suit-able motor so as to be driven at a much higher rate of speed than the mechanism operating the feeding device and thereby draw the board, when the last out has been made therefrom, out of the way of the stud P of the dog N The springs C keep the shaft B normally lowered.

The manner of operating the machine is as follows:The boards from which the barrel heads are to be out are fed to the device from any suitable table, and then passed onto the frame A under the dogs of a bar 11, and between the dogs of the bars E of the table B and the rollers B thereof, below said bars E,

whereby when the shaft M is rotated the table B with its dogs gripping the board advances the latter on the frame A between the side spring rollers M", on the sides of the frame to and beneath the cuttingdevice, where owing to the timing of the parts,itis stopped by the stud P of the dog N abutting against its end. Each of the said rollers is journaled in a bifurcated or forked end of a rod M, which latter has a bearing in a bracket secured to the inner side of the side bars D of the frame, and has a coil tension spring secured to its end within the bracket, and to IIO the bracket so as normally to force said roller against the board on they table B. Similar rollers are used in rear of the cutters for guiding the board from the frame, see Figs. 2 and 3. The parts are so timed that when said stud P engages the board, the clamping head R is. lowered so that it bears upon the board owing to the weight Q on the attached lever P, thereby preventing any lateral movement of the same. At the same time the shafts L and W with theircutter heads M and X are rotated by the proper mechanism, and owing to the Weighted lever L connected with the shaft L, and the weighted lever Y of the shaft W, the cutters bear against the board, so that it is operated on from both above and below, the knife blade or cutters F coming in contact with the board slightly in advance of the other cutters, so as to cut out the head from the board, the gouges or chisels G then beveling the edge portion, and the cutters H planing or smoothing the portion roughly beveled by the gouges. As the one side of the barrel has a larger bevel on one of the faces of its edge than the other, the cam and other parts operating the lower cutter head X are so arranged that its Work, cutting the small bevel, is stopped a short time in advance of that of the upper cutter head M, and it is lowered so as to be out of the way of the said cutters of the head M. While the cutters are at work, the boring tool on the shaft G is also being operated by means of a band connecting its pulley with a pulley on the shaft L, so that a hole or recess is made in the board a short distance in advance and at one side of the barrel head that is be ing formed. During the cutting operation, the table B is removed from the cutters, and the further rotation of the driving shaft removes the cutters, boring tool, and clamping head R from the board, and the dog N is raised so that its stud is above the path of travel of the board, so that the latter may be advanced on the return movement of the table B, caused by the further rotation of the driving shaft S, the part operated on passing with the barrel head from beneath the cutting mechanism to the rear of the frame A, the barrel head falling into the opening F as it reaches the same. The stud P of the dog N during this advance movement of the table, having been lowered during the latter part of the said advance movement now rides on the board, so that when the latter has been advanced the proper distance or the space sufiicient to cut therefrom another barrel head, the said stud P will drop into the recess made in the board by the boring tool. Secured to the levers L and W, and to cross bars of the uprights J are belt guides J X for the operating pulleys of the shafts L and W, said guides being pivoted to said levers and vertically movable on said bars. The further operations of the several parts are as have been described.

When the last out has been made from a board, the first portion of the advance movement of the table B advances the outer end of the board so that it is gripped by the studded wheels A when owing to the rapid rotation of the latter the board is removed from the cutting mechanism and the stud P, before the latter can enter the last hole or recess made by the boring tool, the next board being stopped in its advance by the said stud. Owing to the spring connection, as described and shown, of the, pitman U and arm X of the rock shaft W, the extended or lengthened travel of the table B and advance of the board on the frameA are provided for, without any breaking of the parts by the contact with the board of the stud P The machine by a change of or employment of different cutters maybe readilyadapted for cutting heads of butter tubs or other articles, as can be easily understood.

By having the slot U as before described in the upper part of the connecting bar U,

the connected lever L is permitted to descend a short distance or sufficiently for the cut of the upper cutters, without driving the lever P after the clamping head R has come in .contactwith aboard. It also permits the lever P to be assisted in its upward movement after the upper cutters are free from the board, by means of the mechanism raising the lever L.

To adjust the cutters G or H in position on the cutter .heads the same are slotted as at S see Fig. 4: for a screw T which is inserted in an opening in the cutter head, passing through said slot into a second opening in the rim, the said screw having a reduced portion forming a shoulderU which bears against the cutter so as to keep it in place. The spring dog X see Fig. l which engages the stop on the side of the feeding table B to limit its movementjwhen removed from the path of said stop permits the extreme movement of the table, but when in the path of the stop Y limits the return of the table to the proper place necessary for the advance of the board thereon to the required position for it to be engaged by the clamping heads.

To prevent the operation of the cutters, a lock is employed, said lock consisting of a link V pivotally attached to the arms V which latter are pivoted to the frame A atV. The said link is provided with the shoulders W adapted to engage the under sides of the levers L and Y, when raised, and prevent their descent, and is operated by the rod X which is guided on the frame A. A spring G which is so secured to the lower end of the link and to the frame A, as to be on opposite sides of the lower pivotal point V when the link V is engaged or disengaged respectively with the levers L and Y, to hold the said link in place until operated by the said rod. In the drawings an extra pulley is shown under pulley A the same merely serving as a supporting block for said pulley A Having thus described my invention, what.
