BARlREL-FINISHING MACHINE,

SPELI FIOATION firming part of Letters Patent No. 292,737, dated January 29, 1884. Application filed September 28,1882. No model.)

To ILZZ whom, it may concern:

Be it known that I,- Itonnnr O. DOBBIN, of \Vaterloo, in the Province of Ontario and Dominion of Canada, have invented a new and Improved Barrel-Finishing Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for finishing barrels after they have been set up in truss-hoops.

The invention consists in the construction and combination of parts forminga barreliinishing machine, hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Fig.- 2 is an end elevation'of the same, showing the barrel-planer raised. Fig. 3 is a plan view of part of the machine, parts being broken out and others shown in horizontal section. Fig. 4. is a cross-sectional elevation of the machine 011 the line at 00, Fig. 1. Fig. 5 is a longitudinal elevation of the header. Fig. 6 is a detail plan view of the slotted guide-plate of the same. Fig. 7 is a central cross-sectional ele-' vation of the machine, showing the central chuck opened, and showing the planer lowered upon a barrel resting in the lower part of the chuck. Fig. 8 is a longitudinal sectional elevation of a part of the middle chuck. Fig. 9 is a sectional plan view of the same on the line 1 y, Fig. 8. Fig. 10 is a longitudinal elevation of the rear of one-half of the ma chine, some parts being broken out and others shown in section. Fig. 11 is a cross-sectional elevation of the same on the line a 00 Fig. 10.

.The several parts of the machine are sup ported in a frame, A, and on abaSe-plate upon which the machine rests.

The large revolving chucks B, which form thelathe for holding the barrel while the same is being turned, are formed of two annular plates, B and B", which. are provided with radial grooves b, and which plates are placed against each other in such a manner that the grooves face each other and form radial tracks for the screWspindIesB, which are provided at the ends with dogs 13, adapted to hold the spindles B" pass.

ends of the staves. The 'said dogs are providedwith shoulders or offsets 12, against which the outer edges of the ends of the barrel-staves ends toward the periphery-the spindles B are provided with plates b which have their ends tapered, and which project from the in ner surfaces of the chucks, and which, if united, would form one continuous circle concentric with the outer circle of the chuck. The united plates B and B are provided with a series of slots, 13 at right angles to the spindles B and within these slots cog-wheels B are contained, which are provided with central threaded apertures, through which the screw-spindles .13 pass, whereby when the cog-wheels B are rotated the screw-spindles B will be moved radially to and from the center of the chuck.

On the outer surface of each annular plate 'Ba circular rack, O, is riveted in such a manner that the teeth of the said circular rack will be at right angles to the outer surface of the annular plate B, the teeth of the said circular rack C engaging with the teeth of a pinion, O, mounted loosely to slide on a shaft, which is provided with a driving-pulley, 0 By means of a longitudinal groove on the shaft 0 and a stud or key projecting from the hub of the pinion 0 into the said groove, the said pinion can be caused to rotate with the shaft 0 but can slide "longitudinally on the same withthe chucks. Each chuck is provided with a circular rack, O, which engages with its corresponding pinion, O. A flat ring, D, which is provided with radial cogs on both flat sides, rests against the outer surface of a plate, 13, in such a manner that the teeth on one side of the said ring can engage with the teeth of the cog-wheels B, through which the A circular frame, D is attached by suitable arms to a ring,lE, which surrounds the outer edge of the plate B, which plate B and the plate B attached thereto,

are mounted, which engage with beveled cogwheels D", which are mounted on horizontal shafts E on the front and rear of the frame A, the said wheelsl) being adapted to rotate with the shafts E, and also adapted to slide longitudinally on the same. The hook-arms D in which the beveled cog-wheel D can rotate, move the said cog-wheel with the chucks. At the end, at the right hand of a person standing in front of the machine, the shafts E are provided with beveled cog-wheels E", which engage wit-h beveled cogwheels E, mounted on inclined shafts E, which are provided at the upper ends with worm-wheels E, which are adapted to engage with a worm, E", mounted on a shaft, E on which are mounted the fixed and loose pulleys a, a, a and a". The inclined shafts E are journaled in projections of arms F, which arms have their lower ends mounted on the ends of the opposite shafts, E, and which have their upper ends slotted and united by a transverse pin, which passes through a vertical slot in a frame, F, and through a stirrup, F", surrounding the said frame F, and pivoted to a lever, F, which is pivoted to the frame A. which lever F" is provided with an angle locking lever, F, acted upon by a spring, F", which angle locking-lever F is adapted to catch on the upper cross piece of the frame F. A spring, F, clutched around the screw-shaft G presses the outer 'end of the lever F upward. By means of the lever F the worm-wheels E" can be raised or lowered at will to be disengaged from or engaged with a worm, E.

Horizontal screw-shafts G are journaled in the frame Alongitudinally inthefrontand rear, and a screw-shaft, G, is journaled in the top of the frame A. One half of each screw-shaft is threaded righthanded and the other half lefthanded. At the left hand of the machine the shafts G and Gare provided with beveled cogwheels to", engaging with beveled cog-wheels a. on the transverse shafts a at the end of the maehine-frame,so that if one screw-shaft is rotated the others will also be rotated. The rear screw-shaft, G, is provided at the right-hand end of the machine with a eog-wheel,G,which engages with the cog-wheel G mounted on the shaft on which are mounted theloose and fixed belt-pulleys 0,-0, 0*, and c. The screw'shafts G pass through nuts G, made integral with the rings E, and the screw-shaft G* passes through nuts G at the upper ends of arms Gr",

connected with the rings E, whereby whenthe screw-shafts are rotated the chucks B will be moved toward or from each other. The central chuck, H, consists of two flat,hollow,semiannular boxes, H and H", of which the lower one, H, is fixed, and the other, H, is hinged at the rear end to the lower section, H. The two sections can be locked together by means of a latch, d, which is provided with a hook at its lower end, which hook is pressed against the outer edge of the lowersection, H, bya-spring, d. \Vhen the section H is to be held open, the end of the latch-arm d is passed over the screw-shaft G, as shown in Fig. l- The sections H and H contain a series of radial rods H, which are provided at the inner circular edges of the sections with segmental dogs H, against which the barrel that is to be held rests. The rods H are guided by the inner circular edges of the sections and by apertures in a central circular partition, H", in the sections H and H. The rods H are connected by means of connecting bars or rods H" with cog-wheels H, which are pivoted within the sections H and H in such a manner that the teeth of these cog-wheels H will almost project from the outer edges of the sections H and H'-.- The outer circular edges of the sections H and H are formed by semicircular racks I, with which the teeth of the wheels 11 are adapted to engage. The semicircular rack I (see Fig. 7) of the lower section, H, engages with the teeth of the cog-wheel I, which is rigidly mounted on a short shaft, 1 with which cog-wheel 1 the pinion 1 engages, which is mountedon the shaft 1, which is rotated (see Fig. 1) by means of a worm-wheel, 1", and suitable intermediate gearing, (see dotted lines, Fig. 1, showing gears connecting shaft 1 with worm 1 which worm is rotated by belts passing over the pulleys c on the same shaft as the worm-wheel. It the two sections H and H are locked together, the two semicircular racks I will form one continuous circular rack, and if one rack-section is moved on a circular line the other will also be moved 011 a circular line. The racks I. will act on the cog-wheels H which in turn act on the conneetingrods H and the rods H, and thereby the dogs H will be moved outward from or toward the inner circular edges of the sections H and H".

On the longitudinal shaft J on the upper rear part of the frame A a U-shaped frame, J, is journaled in such a manner that the said frame can swing in the vertical plane and in between the large chucks B B. On the inner end of the said frame J a shaft, J", is journaled, on which are mounted a central belt-pulley, f, and two side pulleys, f. In the swinging end of the frame J is mounted a shaft, J on the ends of which are loosely mounted belt-pulleys f", and between the-said pulleys a concave cutter-head, J connected with the pulleysf is loosely mounted, to which the planing-knives are attached. The contour of the cutter-head J and of the cutting-edges of the knife 1 must be the same as the desired contour of the barrel. The knives 9 should be provided with slots, so that they can easily be adjusted on the cutter-head to project more or less, as may be necessary, and according as they wear off. Belts g pass over pulleys f and f and a driving-belt passes over the pulleyf, so that if the shaft J is rotated the cutter-head will be rotated. The frame J is provided on the outer surfaces of its sides with stop-lugs g, which are adapted to strike on screws in the rings E, to prevent the cutterframe J from being lowered too far. The

IIO

screws canbe adjusted to project a greater or less distance from the rings E, according as the movement of the cutter-frame J is to be adjusted. Rods h extend from the swinging frame J down to the rear end of a lever-arm, 71 of a shaft, h, which is provided with abeveled cog-wheel, h", engaging with a beveled cog-wheel, h", and a horizontal shaft, if, at right anglesto the shaft If and parallel with the arm h, which shaft h is provided at the end with a treadle, h, whereby when the treadle is depressed the cutter-frame will swing downward. Springs j, coiled around the shaft J, act on the under edge of the swinging frame J and throw the same upward.

To the outer surface of the rings D circular plates K are attached, which are provided with curved side springs, K, which are adapted to rest against the edges of the barrel-heads, which are placed against the plates K, and thus hold the said barrel-heads against the said plates. A shaft, L, adapted to rock on its longitudinal axis, is journaled in the front of the frame A, and in the middle of the s tid shaft a pinion, L, is j ournaled in such a manner that its axis will be at right angles to the axis of the shaft L, and the shaft of the said pinion is provided at its outer end with a crank-handle, L". The pinion L engages with racks attached to bars M and M, respectively, above and below' the shaft L and parallel with the same, which bars are guided to move longitudinally by transversely-slotted guide-block M, held rigidly on the shaft L. The two ends of the upper bar, M, pass through the upper slots of the guide-blocks M", and the ends of the lower rack-bar, M, pass through the lower slots of .clearly shown in Fig. 6.

the guide-blocks M",

' A sliding block, N, is mounted on the shaft L to the right of the pinion L, and the said block N is connected with the upper rack-bar, M. A like sliding block, N is mounted on the shaft L to the left of the pinion L, and is connected wit-h the lower rack-bar, M, each ofwhic h sliding blocks N N is provided with an arm, N, which is provided at its end with a disk, N", having a series of studs, 70, which project toward the plates K. The outer end of the rack-bar M is provided with a'stud,

k, which passes through a slotted plate, 0.

The plate 0 is provided along its inner edge that is, along the edge toward the interior of the frame A-witha longitudinal slot, 0, which is provided at its middle wit-h a slight curve. At the right-hand end of the slot 0 a small transverse slot, 0', leads to a slot, 0*, parallel with the slot 0, which slot 0 is so located that one part is a short distance to the rightof the outer end of the slot 0", and the other part is to the left of the slot 0", as is The pintle k, which passes through the slots 0, O, and 0, guides the arms N during their movements, as will be fully described hereinafter. Two horizontal shafts, P and P, are journaled parallel with each other and parallel with the longitudinal axis of the machine on a plate, P,

which is adapted to rock in a vertical plane and transversely to the longitudinal axis of the machine. The said plate P" has at its outer or front edgea. rod, which is connected by a connecting-rod, P with an arm, P, of ahorizontal rocking shaft, P provided with a treadle, P, which is pressed upward by a spring, A". By depressing the treadle P the plate P" will be swung in the direction of the arrow, as shown in Fig. 2. On the shafts P and P pulleys Z and Z are loosely mounted in such a manner that they can slide longitudinally on the said shafts P=and P, but rotate with the same. A stirrup-frame; .Z", pivoted on the rod P is swung over the pulleys l and l, and holds them in place, the ends of the stirrup being held stationary on the rod Plby the end of the eonnectingrod P when the plate P is moved. The rocking plate P is mounted on a shaft, m, on which it can rock and slide, and is connected by a bar, m, with a vertical arm, m of a transverse rocking shaft, m, the other end, m", of which is connected by a lever, m with one end of a crossarm, a, mounted on a horizontal transverse cross-shaft, 0, provided with a handle-lever, 0. The rocking plates P are provided in each half of the machine, and by means of the handle-lever 0" of the shaft 0 both rock ing plates canbe moved toward or from the middle of the machine at the same time.

A cutter-'head, Q, on the inner end of the shaft P is provided with a cutter, Q, for crozing and howeling the barrel, and with abeveled cutter, Q for beveling the ends of the staves. A cutter-head, Q", mounted on the inner end of the shaft P, is provided with a cutter, Q, which planes the outer surfaces of the ends of the stavesthat is, those surfaces which are not acted upon bythe planer J or the parts below the pulleys f The tension must be removed from the belts rotating the shafts P and P when the plates P are being shifted; The cutting-blades in the heads Q and Q can be adjusted by means of screws passing through slots in the said cutters. The plates P carrying the shafts P and P, are adapted to oscillate to admit the crozing-cutters Q topass into the thickness of the staves without cutting entirely through the chiming;

All the above-described cutting-tools of the machine operate at the same time.

A horizontal shaft, R, is journaled in the frame A and in an arm, R, of one of the rings E,. in such a manner that the said shaft can slide longitudinally in its bearing in the frame A On the inner end of the shaft R is mounted a pinion, R", which engages with a rack, R, which slides diagonally on the inner surface of one of the chucks B. The said rack is provided at its upper end with a fork, R, having its open end facing the plate B, between the shanks of which fork the beveled plates 1) at the ends of the screw rods or adapted to pass.

On the outer end of the shaft R a cog-wheel,

spindles B are S, is mounted in such a manner that it will I near the ends of the barrel. The center chuck turn with the shaft B, which, however, can slide within the same. A vertically-moving rack, S, engages with the cog-wheel S, audits upper end is mounted in an arm, 5", projecting from the frame A. The said rack-bar S is provided with a series of beveled projections, 'r,which can be adjusted and locked in the desired position on the bar by means of nuts r. An angle-lever, T, pivoted on the end of the arm S, is provided at its lower end with a beveled spur, s, which faces the beveled projections r of the bar S, and at its upper end itisprovided with a finger, x, which is adapted to pass into the apertures 1 and 1 in a flat longitudinally-slidi11g bar, 1', above the belt-put leys a, a, a", and a, into which apertures the finger s is pressed by a spring, x".

To the sliding bar U elongated loops U, through which the driving-bolts pass, are attached. A horizontal lever, V, passes through a clip on the bar U, and is used to shift the same. Spiral springs Y surround a slotted shaft, Y, through which the lever Y passes. 30th springs act to press the lever Y toward the middle of the bar 17. Cheek-studs care provided on the slotted shaft Y, to prevent the springs from pressing the lever too far in one direction or the other. A. flat longitudinally-sliding bar, 'W, is held above the pulleys c, c, c, and r", and is provided with elongated loops \V, through which the belts pass, and with apertures a and '12, into which a finger at the upper end of an angle-lever, \V, is adapted to pass, and into which it is pressed by a. spring. The lower end of the said lever \V" rests on a longitudinally-sliding bar, Y, connected with one of the movable chucks B, and at its outer end it is provided with a series of adj ustable beveled projections, Y, against which the beveled side edge of the lower end of the lever \V is adapted to rest. A pivoted horizontal swinging lever, X, passes through a clip in the bar \V and through a slotted shaft, X, which is surrounded by springs X, both of which press the lever X toward the middle of the shaft X. A locking-pin, 1r, which passes through one of the rings E, is adapted to pass into a notch or recess in the corresponding plate, B, and is attached to a lever, 1r, pivoted on the ring E, which lever is pressed upward at its outer end by a spring, a *0 that the pin 10 will a]- ways be pressed inward.

To each ring I) a cross-piece, 1', is attached, which is provided with a checking, i, against which the end of the sliding plate 1 strikes, to prevent it from injuring the chuck. ()n the lower part of the cross-piece i a finger, if", is provided, between which and the side surface of the ring E the pinions C are located, so that the said pinions will move longitudinally on the shaft 0 with their respective chucks.

The operation is as follows: The stavcs are first set up in trusshoops, and when a barrel is placed in the center chuck, H, the stavcs are held together by two hinged truss-hoops is then closed upon the center of the barrel, and is locked by means of the latch 11. By means of the belts passing over the pulleys c c, the shaft I and the pinion 1 are rotated, and they in turn rotate the cog-wheel I on the shaft 1, which cog-wheel I rotates the racks I of the center chuck. According as the racks I are rotated in one direction or the other, the cog-wheels H within the chuck H will be rotated in one direction or the other, and the rods H, on the inner ends of which the segmental dogs H are secured, will be moved toward or from the center of the chuck. If the above-mentioned shafts and cog-wheels are turned in such a direction that the dogs I-l' move toward the center of the chuck, they will press against the barrel, and will thus firmly hold the same in place. Then the barrel is to be grasped by the revolving chucks B. By means of the belts acting on the fixed pulleys a or a, the dogs B can be moved to ward or from the centers of the revolving chucks B. The motion of the shaft 011 which the belt-pulleys are mounted is-transmittcd, by means of the worm E, the worm-wheels E", the shafts E, the beveled cog-wheels E and E the shafts E, the beveled cog-wheels D and I), the shafts D, the beveled cogwhecls D, the beveled cog-ring D, and the cog-wheels B, to the screw-spindle B, to which the dogs are attached. All the dogs move simultaneously, and are so adjusted that when the chucks B B are moved toward each other the shoulders b of the dogs will rest against the outer edges of the ends of the stavcs, as shown in Fig. 3. To move the chucks B to ward or from each other, the pulleys c and c are rotated, whereby the cog-wheels G and G will be rotated, and the latter will rotate the shaft G on the rear of the machine, which, by means of the transverse shafts a and the beveled pinions a and (15, rotates the top screwshaft, (l, and the front screw-shaft, G. As the screw-shafts above mentioned pass through nuts connected with the rings E, the chucks will be moved toward or from each other by turning the said screw-shafts. If the dogs B have been previouslyadjusted according to the diameter of the end of the barrel, and the chucks B are moved toward each other, the stavcs will be clamped between the grasping-dogs of the opposite chucks, which dogs must be firmly set thereon. The upper section of the center chuck, H, is then swung upward, and is held raised by hooking the free end of the latch-lever d over the middle of the screw-shaft G, as shown in Fig. '7. The planer J is then lowered to be in contact with the barrel by pressing down the treadle h, whereby the shaft 71? and the beveled cog-wheel h at the end of the same will be rotated, and will rotate the beveled cogwheel h" and the shaft If, on which it is mounted. Thereby the arm h of the shaft If will be swung downward, and will swing the frame J downward, which is connected by means of the rods or wires h with the said arm 71/. The screws 9 are so adjusted that the check-studs attached to the sides of the frame J, will rest on the same when the cutter J is in contact with the barrel. As the cutter is continually rotated it will plane off the barrel, which must be rotated one revolution at the same time, so

' that all the parts of the outer-surface of the barrel will be planed. To rotate the chucks B B, the locking-lever I is disengaged. from the upper cross-piece of .the boXF, and by means of the lever F the stirrup F is raised, whereby the upper ends of the hinged frames F will be raised. and the worm-wheels E will be disengaged from the worm E, so that when the shafts E arerotated by the rotation of the circular rack D, which rotates with the chucks B, they will not offer any resistance, as other wise, if resistance were offered, or if the shaft E could not be freely rotated. by the cog- .wheels B, as the rack D was rotated, the said cog-wheels B would rotate, and would cause the dogs 13* to be pressed against or moved from the barrel, which, by the disengagement of the worm-wheels E, is obviated. After the wheels E have been disengaged from the worm E", the shaft 0 is rotated by means of the belts passed around the pulleys G", whereby the pi nions C will be rotated, which engage with the circular racks 0, attached to the plates B of the chucks, whereby the said plates will be rotated and the barrel held by the two chucks will also be rotated. Before the chucks can be rotated the outer end of the lever w must be depressed to release the plate B from the ring E. As soon as the plate B has made one revolution, the pin w automatically snaps into the notch or aperture in the edge of the said plate and locks the same in position. The barrel is then again grasped by the center chuck, the truss-hoops are taken off, and then the dogs of the revolving chucks are separated a greater distance, and the revolving chucks are moved m ore toward each other, so as to permit those parts of the staves at theends which have not been planed by the planer J to project from the revolving chucks sufiicien-tly to be acted upon by the knives Q on the revolving cutter-head Q. Those parts of the staves below the pulleys f of the planer J* are not acted upon by the said planer, and must be planed by the rotary cutter-head Q, and the sliding plates P are then so adjusted that the knives on the cutter-headQ plane off the abovementioned ends of the outer surfaces of the staves, and the knives Q and Q on the cutterhead Q croze and howel'the barrel and chamfer the ends of the same, the barrel being rotated once by means of the chucks B- during the time that the above-mentioned cutters act on it. .By raising the free end of the handle 0 the shaft 0 will be rotated, the cross-arm n will be rocked, the connecting-arms m will be turned toward the shaft 0, and this will cause the arms on and m of the shaft m to move in the same direction. As the'arms m are connected with the under sides of the plates 1?",

' and chamfered, the handle 0 is swung down ward, whereby the plates 1? and the cutters thereon will be moved back. The barrel is now ready to receive the' heads, which are placed against the plates K, attached to the rings D,"against which plates the heads are held by the clamping-springs K. The stud k at the outer end of the bar M of the header rests at the righthand end of the outer slot, 0", and the studded plates N* at the ends of the arms N will be a short distance from the heads held on the plates K. By turning the crank L the stud k is moved toward the left hand of the slot 0 and thereby the studs k 011 thedisk N will be forced into the barrelhead. Then by reversing the movement of the crank-arm L the stud 7c is moved to the transverse slot 0, and by allowing the crank-axle to move upward the shaft L will rock on its longitudinal'axis, and the arms N will swing downward, so that the disks N, holding the barrel-heads, will be opposite the middle of the ends of the barrel. Then by turning the crank L the stud It" will be moved toward the left-hand end of the slot 0, and the arms N, carrying the heads, will be moved toward the ends of the barrel until the said heads are within the ends of the barrel. The portion 0 of slot 0 is in position to so guide pin k that the studs will enter the barrel-head while held on plate K, and the length of slot 0 is sufficient to allow motion to crank L to force said studs into the head. The cross portion 0 of the slot is to allow pink to rock therein, carrying arm N and the barrel-head on its studs 70 in front of the open barrel. The long slot 0 permits pin k -to play far enough for the barrel-head to be thrust into the barrel.

During the time that the heads are being inserted the ends of the staves must be held by the dogs B but as soon as the heads have entered the barrel the chucks B are moved from each other, andall the dogs are moved toward the periphery of the chucks, so that the ends of the staves will be released to allow them to receive the head; but the exact manipulation of the chucks B and dogs B in entering the head will be dependent upon the nature and condition of the staves or of the stock from which the staves are made. The barrel is now ready to receive the hoops, which are placed on the opposite ends, while the barrel is being held at the middle by the central chuck, H, only. The hoops are forced on by means of the chucks B. The dogs are to be adjusted for each hoop, the shoulders I) of the dogs resting against the outer edges of the hoops, and then by moving the chucks B to ward each other the hoops will be forced firmly on the barrel. Each .pair of hoops is forced on successively in this manner. The above chucks may also be used to holdthe barrel for sandpapering, polishing, or painting it. If ahoop is to be secured on the barrel, the said hoop must be held by the dogs B, which must be brought economical. All the hoops, heads, staves,&c.,

together, so that each dog rests on the outer surface of the hoop; and when the 1100p is held the movement of the dogs must be stopped, which is accomplished by throwing the belt from the fixed pulleys c or (13'' upon the loose pulleys a or a". If the bar S is moved upward and one of its projections r strikes the spur s at the lower end of the angle-lever T, the projection s at the upper end of the said angle-lever T moves downward and out of the aperture t or t of the sliding bar U, and thus throw it in one direction or the other. The releases the same, permitting the springs Vto bar S is moved by the cog-wheel S on the shaft R, which is rotated by the pinion R, which is acted upon by the bar *3, provided at the upper or inner end with the fork It. As the beveled plates I) at the outer ends of the spindles B pass through between the shanks of the fork R", they gradually move the said fork toward or from the center of the chuck, according as the plates b are successively a greater or less distance from the center of the chuck. For instance, if the belt is to be shifted at a certain time, the bar S is so adjusted that at the right time it will be moved downward, and one of its projections 0' will strike against the lower beveled spurs of the lever T, thus releasing the bar U and throwing the belt upon a loose pulley, whereby the movement of the dogs 13* will be stopped. The belt must be shifted upon the fixed pulleys by hand by moving the lever V.

The objectof providing the automatic releasing meehanisin is to avoid the trouble of watching the dogs until they are in a propor position, whereby considerable time and labor are saved.

If the hoops are to be forced upon the barrel, the chucks must be moved toward each other, the hoops being held by the dogs 13. \Vhen the chucks have moved toward each other the desired distance, the belt must be shifted from the fixed pulleys c or c.upon the loose pulleys 0 one. The rod Y moves with one of the chucks B, and is provided with the beveled projections Y, and when one of the same strikes the lower beveled end of the lever V the projection at the upper end of the same will be drawn out of the apertures 12 or 'vof the box V, which is thus released, and can be thrown in one direction or the other by the springs f whereby the belts will be shifted. All that is necessary is to adjust the beveled projections Y on the bar or rod Y in such a manner that the bar \V is released at the proper time. The belt must be shifted on the fixed pulleys c and c by means of a handlever, X, and are shifted from the said pulleys automatically. The above-described machine can be adjusted to make barrels of different sizes; but separate machines will be required to make hogsheads or for making small kegs.

It is designed that the machine shall produce barrels of one size only, and thatis most of one barrel will fit any other barrel of the same kind, and the cost of manufacturing or repairing barrels is thus materially reduced.
