BARREL-MACHINE.

SPECIFICATION forming part of Letters Patent N o. 591,003, dated October 5, 1897. Applicationiiled October 30, 1895. Serial No. 567,427. (No model.)

To all 'who/1t it may concern.:

Be it known that I, ROBERT NAWRATH, a subject of the Emperor of Germany, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Parrel-lliachines;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this speciiication.

The objects of this invention are generally to set the staves of a barrel in position to secure the usual cylindrical form 5 to enable the ends of said staves to be trimmed by chamfering,grooving,and crozing while said staves are in such position; to admit of the application of certain hoops, known as the trusshoops, by which said staves are held in position before removal from the machine; to facilitate the operation of assembling the parts, and to reduce the cost of construction.

More specific objects of the invention are to so hold the staves in position as that when turning out the grooves in which the barrelheads are secured said staves will not spring out of position 'with parts of the machine, and thus cause the turning tool to produce a spiral groove rather than a true circle, as in certain machines heretofore experimentally produced; to provide the cylinder over which the staves are arranged when forming the body of the barrel with greater strength to resist the strain brought to bear thereon when said staves are fed to the machine; to facilitate the operation of fastening the staves last fed to the machine in place; to provide a more firm and secure support for the cutters when in position for operation upon the staves, whereby a more smooth and even cut is effected and the danger of bending or twisting the cutter-shaft avoided, and to secure other advantages and results, some of which will be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved barrel-forming machine and in the arrangements and combinations of parts, all substantially as will be herein afterset forth, and finally embraced in the clauses of the claim.

Referring to the accompanyingdrawings, in which like letters and figures indicate corresponding parts in each of the several views, Figure l is a front elevation of the improved machine, showing the general'relalions of the various parts. Fig. 2 is a side elevation of a collapsible frame over Which the barrel is formed. Fig. 3 is a section of the same, taken atline m. Fig. 4 is a detail elevation of portion of a feed-roller shaft, and Fig. 5 is an end view of a coupling-piece for the same. Fig. 6 is a sectional View of the frame, showing the parts in their collapsed relations, the section being taken on line nc. Fig. '7 is a section taken at line y. Fig. 8 is a central longitudinal section of said collapsible frame enlarged. Fig. 9 is a side view of a por-tion of the machine, showing the means for fastening the staves finally inserted to complete the barrel-body. Figs. l0 and 11 are details showing the construction of a shifting cutter for trimming the edge of the barrel; and Figs. l2, 13, and 14 are respectively a side View, a plan, and a view of a preferred arrangement of cutters for forming the groove, Croze, and chamfer at the edges of the said barrel.

In said drawings, @indicates a suitable bedplate, having stands d d, providing boxes or bearings for a driving-shaft b, and having proj ectin g bearin d" for driving-shaft supports c c, which latter are connected so as to work to and from the shaft o simultaneously and together. Said bed-plate also has bearings ct'" for a sawespindle-driving shaft CZ. On said bed-p1ate is also fastened a carrier e, provided with slideways f, in which certain slide-pieces g of sweeps h h h Work horizontally, the said sweeps being adapted to lie outside of and around the barrel and to guide the staves into position as they are fed to the machine. Said sweeps are in posi tions` to give, in connection with a collapsible frame, the necessary bulge or rotundity to the periphery of the barrel. In Working horizontally on said slideways f said sweeps come together and separate, the latter movement occurring after the staves are in position, trimmed, and provided with truss-hoops, and thus said barrel may be removed from the IOO machine. This movementof sweeps, however, is not new in this machine, but has been employed heretofore. The sweeps operate simultaneously, movingin opposite directions under the influence or power derived from the main-shaft supports, which act as levers, as shown in Fig. 9, the fulcrums of which are on the sleeves (l, arranged on the shaft d.

The lever-like supports c c are connected, as at i, with the shorter sweeps h', the connections being slotted to allow for the pivotal movement of the lever and the longeror rear sweeps 7i," being in train with the levers c by means of walking-beam leversjl and con neeting-rods 7o 71;. A handlever l, Fig. 1, and cooperating means are provided for easily operating the levers c and their connections, but these do not form a part of my particular improvements, the subject of the present patent. The lever-like supports c care connected at their upper or free ends by a suitable coi'inecting-bar m.

The bearings in the supports c'for the driving-shaft b are shown at 'n in Fig. 9, where one of said supports is shown to be recessed at one side to receive said shaft at a point. corresponding with the axial center line of the sweeps lt and opposite the ends of the correspondiugly-recessed arms o, projecting from the rear sweep h" laterally and then centrally, so as to lie outside the ends ofthe barrel and toward the shaft b, as indicated. The parts c 0 thus cooperate to form boxes for the shaft b, which boxes have no independent fastenings requiring` time for manipulation, but open automatically when the parts c. h are operated as described. The driving-shaft supports c are also provided with suitable brackets or bearings p (omitted from Fig. 9. buty shown in Figs. 1 and 1l) for the shaft s q q, on which are the circular saws or cutters for chantfering, crozing, and grooving the stave ends after the staves are in position to form the barrel and before said barrel is removed from the machine. Said circular saws or cutters are arranged to work simultaneously, being given a longitudinal movement by which they are presented to the stares by a hand-ratchet o", working on bearings formed on a slile s and engaging a rack ton a slide t. The slide s carries the cutters toward the end of the barrel when operated by the hand-ratchet r, and the slide f, when operated by the screw a, regulates the depth of the groove in which the heads of the barrel are inserted.

Referring to Figs. 12, 13,and 14, where the preferred construction isillustrated in detail, it will be observed that the trimming and chamfering cutter o and its connections are coupled tothe groovingand crozing cutter yU', so that the two operate together when operated by the hand-ratchet r. Each coupling consists of a link w, which extends from one saw-spindle q to the other, as shown in Figs. 12 and 14, Washers w being employed to secure the desired adjustment. Pulleys 3 3 give rotary motion to the shafts q and circular cutters, motion being transmitted thereto from the pulley-shaft d by belts 4, Fig. 1, in any suitable manner. The shafts q slide longitudinally in the pulleys 3 to shift the cutters, the pulleys 3 remaining in position to properly receive power from the belts, said shafts being provided with suitable feathers or keys to prevent independentrotary movement.

By means of the simultaneous movement of both the trimming and chamfering and the .erozing and groovin g cutters great exactness and uniformity are secured in the shaping of the staves,and by moving the boxes in which the shafts rotate longitudinally with said shafts the latter are prevented from springing or bending, and as a result a true circular groove is produced, and the danger of twisting off the ends of the spindles because of lateral pressure on the cutters is greatly reduced or entirely avoided.

In arranging the staves in position I employ, in connection with the sweeps h' h, a collapsible frame, (shown more clearly in Figs. 2, 3, 6, 7, and 8,) the sweeps lying outside of the barrel and the said frame on the inside. A collapsible frame in a similar position has been employed before; but the construction of the one hereinafter described is new and useful in that it is stronger to resist the great pressure brought to bear thereon and in holding the staves true to correct position, so that the grooves, cc., will be properly formed by the cutters.

Upon the main drivin g-shaft @between the bearings for the saute, provided by the supporting-levers c c, are arranged disks 5 These are firmly keyed to the shaft and rotate therewith. Between said disks is arranged a sleeve 6, which is loose on said shaft, and thus is allowed an independent movement thereon. At one end of said sleeve 6 is keyed a gear-wheel 7, which meshes with a series of small pinions or cog-wheels 8, Figs. 2, 7, and S, strapped to the inside of one of the disks 5 and arranged on arbol-s 9, which have bearings in the straps and said disks and extend through the latter, from whence said arbors project and are provided with angular heads 10, adapted to receive a handcrank, by which said pinions S, gear-wheels 7, and sleeve 6 are turned by hand when the frame is to be collapsed or extended.- The disks 5 also provide bearings for a series of shafts 1l, which extend from one disk to the other in lines parallel with the main shaft, but ata distance therefrom. Suitable means are provided for securely holding said shafts 11 in place. On the sleeve 6 are also keyed two gear-wheels 12 12, the teeth of which are not continuous, but at points corresponding in number with said shafts 1l the teeth are missing, as shown in Figs. 3 and The said gear-wheels 12 12 are provided with long inwardly-extending hubs 13, on which are keyed star-wheels 14 14, the gear-wheels 12 and star-Wheels 14 being thus movable to- IOO IIC

gether. On the shafts 11, adjacent to the gear-wheels 12, are two sets of pivotal interior stave-supports, the supports of one set alternating with the supports of the other. The supports 15 have cogs 16, which mesh with the eogs of the gear-wheels 12. Said stave-supports 15 are angular in general outline in side view, as in Figs. 3 and 6, the pivotal bearings being on the inner arms 18 thereof, having thecogged segments 16. The outer arms 17 of the supports are segmental and, together with alternating segments of the supports 21, form, when the frame is disteuded, the circular bearings on which the staves are arranged to form the barrel-body. The outer or free ends of the segment-arms 17 are, when in their disteuded positions, adapted to rest upon the outer extremities of the rays of the star-wheel 14E, t-he said rays serving as supports, which give great firmness and rigidity to the said arms and render them capable of resisting great pressure.

Fastened upon the gear-wheels 12 are loek ing-arms 19, adapted to engage at certain times the hubs 2() of the stave-supports 15, the latter being cut away on lines concentric with the shaft h at one side of their periphv eries to receive the ends of said arms 19, so

that the said hubs are locked, and the supports 15 are prevented from turning on their shafts independently when the cogs 16 are brought to points of-coincidence with the spaces formed in the wheels 12 by the missing teeth, as will be hereinafter more fully described. Upon the same shafts 11 with the stave-supports 15 are other stave-supports 21, similar to those first described, excepting that they are without eogged segments engaging with the gear-wheels 12. Said supports 21 are operated by the supports 15, the latter being provided with lateral projections 22, which underlie the outer segments 23, as shown in Fig. 8, and thus when said supports 15 are turned to their distended positions the projections 22 slide along the under sides of said segments 23 and force the latter to their outward positions to make complete circles. Reverse action of the supports 21 is occasioned bythe springs 24, which connect said supports 21 preferably withV the star-wheel, so that when the projections 22 move backward the said springs may act to draw said supports 21 to their folded or collapsed relations. The su pporting-rays of the star-wheel are also provided with lateral projections 25, Fig. S, which engage the projections 22 of the arm l5, which projections underlie the segments 23 of the stave-support 2l. These projections are arranged and the movements timed so as to come into engagement at the proper moments and be out of the way at other times when the parts are being collapsed.

ln operating the Vcollapsible frame after the staves have been arranged in position, trimmed, and provided with truss-hoops to enable the barrel to be removed therefrom I `first open the sweeps by operating the handlever l or in any other manner common in the art. I then take a hand-crank and apply it to the angular head 10 of one of the arbors 9, the crank being applied to that arbor which happens to be free of obstruction, and particularly at one side or the other of the arms o toward the rear of the machine. By turning said arbor a pinion 8 is turned, and this, engaging the gear-wheel 7, keyed to the sleeve 6, transmits motion to said sleeve 6. In turn motion is transmitted from said sleeve to the hubs 13 and gear-wheels 1.27 which work with the said sleeve. With the hubs 13 and the sleeve 6 also work the star-wheels 14 and locking-arms 19. The rays of said star-wheel move from beneath the projections 22 of the stave-supports 15, and the locking-arms 19 move from under the attened bearings of the hubs 20 of said stave-supports 15. At the initial time of movement. of the said rays and locking-arms from beneath their roper ating bearings the gear-wheels 12, which at four (more or less) points on the peripheries thereof have missing cogs or teeth, are disengaged from the toothed or cogged segments 18, but immediately upon the 4said locking arms and supperting-rays passing from their locking and supporting positions the teeth or cogs of the gear-wheel 12 intermesh with the cogs or teeth 16 of the segments 1S, and as a result the supporting-arms 15 are turned in wardly on their fulcrumal or pivotal bearings 11 to their collapsed positions, as shown in Fig. 6. The action of the arms 15 serves to remove the projections 22 from supporting or holding relation from the stave-supports 23, and thesprings 24 are allowed to act to draw on said stave-supports 23 to draw them also to their collapsed positions.

To open the frame again, the operation of the crank and parts in train therewith is simply reversed, the projections of the stave-supports 15 sliding on the under side of the stave-support segments 23 and pushing the latter outward until the parts are all in position to produce the continuous circles, as will be understood.

The operation of the parts thus described leaves the barrel loose on the frame, so that itA can be moved easilj` endwise along the shaft b. To enable said barrel to be removed from said shaft, which is a continuous one, and

therein dilt'ers from those of certain machines ,heretofore in use in which the frame was pivoted upon twoindependent shafts constructed to allow the removal of the barrel between. This prior construction, however, was the occasion of weakness in the machine and the consequent imperfections in the results thereof already referred to.

In my construction the shaft is, as before indicated,continuous, the one shaft having bearings at opposite sides of the barrel,so that great rigidity and strength are required. To enable the barrel to be removed from the shaft easily and with convenience, I provide the ICO IIO

said shaft with what I term an outside bearing 26, arranged at one side of the machine at a little distance from the body of the machine, the distance between said body of the machine and said bearing being at least equal to the length of the barrel, so that said barrel may be arranged temporarily therebetween. The said bearing is in sections, the portion 27 being firmly secured to the floor or other fixture and provided with a pivot or fulcrum 28 and the portion 29 being, leverlike, fulcrumed on said pivot and having at one end a weight 30 and at the opposite upper end a socket 3l, into which the shaft may rest. When t-he barrel is to be removed, the

. lever l is turned down, as already described,

and the sweeps h" moved oppositely and horizontally from the levers c, so that the bearing-boxes formed by the arms o and said levers c are opened. Vere it not for the outside bearing 26, it is evident that the shaft would bend or fall at its end on which the barrel is arranged, the bearings in the supports or stands Ct a.' being insufficient; but by having the supplemental or outside bearing this danger is avoided. The sweeps being opened the barrel is pushed along the shaftto the outside bearing, after which the sweeps are again closed and the shaft b again clasped by the bearings 0 c, as will be apparent.

While a new set of staves are beingr fed to the machine, the barrel on the outer end of the shaft is removed by simply raising the weight 30 and turning` down the arm of the lever 29. After removal the bearing assumes a shaft-supporting position automatically.

In feeding the staves to the machine,where by they are made to lie side by side as ordinarily found in barrels, the operator opens up the forward sweeps by turning the hand cam or lever 32 and opening the gates 33, which close the feeding apertures or entrance-ways for the staves. The central sweeps are not ordinarily gated, but the feeding-entrances remain constantly open.

Gates, while not broadly new, have been of a construction and arrangement which materially interfered with a quick and convenient feeding of the staves. In the present case I simply pivot the gates upon the upper ends of the forward sweeps, so that by turning them backward they lie away considerably from the point of entrance beneath the feed-rollers 34 and hang down, so as to be out of the way of the workman in positioning the staves prior to insertion.

To hold the gates down upon the staves last inserted after the annular space formed by the interior frame and outer sweeps are fully occupied by staves, I employ the hand cams or levers 32, which are loosely fulcrumed or pivoted on the feed-roller shaft 35. By simply turning the handles of said lever forward after closing the gates said levers are pressed down against the gates, and the latter press the last-inserted staves rmly down in place,

so that the said staves may be subjected to the action of the cutters when turned by the rotary action of the feed-rollers 24 and the interior frame rotating with the shaft b.

The feed-roller shaft 35 is of novel construction and facilitates operation. In 1Figs. 4 and 5 said shaft is shown in detail atits end receiving power from the train of cog-wheels 36, communicating with the main drivingshaft b. In a prior device the feed-shaft was a single bar of metal operating in connection with a cup working with one of said gearwheels. The different pressures due to variations in the thicknesses of the staves variously affected the pressure of the shaft upon the sides of the said cup, so that when the staves were thick and the pressure great it was difficult, if not impossible, to disconnect the shaft from said cup, and much time was frequently lost in attempting the separation. In the present case I dispense with the cup and employ with the cogs 36 a shaft-section 37, which works in the bearing 38 of a bed a or a stand a' thereof. At the inner end of said shaft-section the same is provided with an annular end or head 39, which works in a correspondingly-shaped socket of a coupling 40, the said socket being opposite a transverse slotll in the other end of said coupling, which slot receives a tongue 42 of the body portion of the feed-roller shaft. The tongue 42 has a freedom of movement or play in said slot, so that the pressure due to the difference in the thickness of the staves above referred to cannot cause a binding of parts and a difficult separation preliminary to opening the sweeps. When said sweeps are to be opened, the said coupling 40 is simply pushed upon the angular head 39 away from the tongued shaft, so as to clear the same when moving the feed-roller shaft with the parts c c.

The operation of the particular improvements of my invention having been quite fully described in connection with the description of the construction and arrangement of parts, further description is deemed to be unnecessary.

Having thus described the invention, what I claim as new is l. In a barrel-machine, the combination with a continuous shaft, eXtensible entirely through the barrel, means for rotating said shaft, permanent bearings at one end of said shaft, a separable bearing toward the other end of said shaft, and a supplemental bearing arranged and constructed to admit the passage of the barrel-body therepast, and a collapsible frame arranged on said shaft, substantiallyas set forth, for the purposes stated.
