JOSEPH L. WALKER, OF BATON ROUGE, LOI IISIANA, ASSIGNOBTO THE K-D BARREL I & PER (70., OF BATON ROUGE, LQU'ISIANA.

MACHINE FOR MAKING BARBELS.

Application filed December 19, 1922. Serial'No. 607,828.

To all whom it may concern:

Be it known that I, JOSEPH L. WALKER, a citizen of. the United States, residing at Baton Rouge, in the parish of East Baton Rouge and State of Louisiana, have invented a new and useful Machine for Making Barrels, of which the followinglis a specification. Y

This invention relates to machines for making barrels, one of the objects of the invention being to provide a machine designed for rolling veneer with hoop and linerstrips so as to produce a complete barrel.

Another object of the invention is to provide a machine of this character utilizing a collapsible drum or former the parts of which are mounted in a novel manner whereby all portions of the periphery of the drum can be shifted toward or away from the axis of rotation, thereby to collapse or to expand the drum.

Another object is to combine with the drum a novel arrangement of pressing rolls one of which cooperates with the drum to constitute means for feeding the stock around the drum. 1

A further object is to. provide endless means for feeding the [stock to the drum, said means being actuated by the drum pulling on the stock during the feeding operation.

A'further object is to provide the feeding means with stock gripping means adapted to automatically release the stock during the completion of the feeding operation, thus to leave, the feeding means stationary preparator to forming another barrel.

1 still further object is to provide improved means for positioning the bottom head of the barrel on the drum or former prior to the rolling of the stock about the drum.

Other objects are to provide improved means for removing formed barrels from the drum and to release the finished barrel from engagement by the pressing rollers during the removal ofthe barrel.

With the foregoing and other objects in view which will appear as the description proceeds the invention consists "of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

Figure 17 is a plan view showing the staves, hoop strips and liner strips assembled prior to being rolled into a barrel.

Referring to the figures by characters of reference 1 and. 2 designate spaced frame members in which is journaled the drum shaft 3, this shaft projecting across the space between the frame members and beyond the frame member 2 to a point adjacent an opening 4 formed within a third frame member 5. The frame members are formed with standards 6 suitably connected and in two of these standards is journaled the main drive shaft 7 which, if desired, can be provided with a belt wheel 8. A gear 9 is secured to the shaft and meshes with a large gear 10 secured to a counter shaft 11 journaled in said standards. Another gear 12 is loosely mounted on the shaft 11 but is adapted to be coupled to the shaft by means of a clutch 13 feathered on the shaft and connected to an operating lever 14 or the like. Gear 12 meshes with a large gear 15 secured to shaft 3. Thus it will be seen that when gear 12 is coupled to shaft 11 motion will be transmitted from shaft 7 to the drum shaft 3.

Journaled within all of the standards 6- is a shaft 161m which is loosely mounted a gear 17 nieshing with a gear 18 secured to the drive shaft 7. A clutch member 19 is feathered on shaft 16 and is adapted to be shifted by a lever 20 or the like, thus to her 1 as indicated at 26. A pawl 27 is pivotally connected to lever and is supported on a ratchet wheel 28 secured to shaft 3. Thus when the pitman 24 is reciproeated the pawl 27 will be oscillated. This will cause the ratchet wheel 28 to rotate intermittently. Under normal'condit-ions shaft 16 does not rotate but when gear 17 is coupled to the shaft the stitching mechanisms 22 will be actuated by cams 21 and during pauses in the stitching operations the ratchet wheel 28 will be rotated intermittently.

That portion of the shaft 3 located between the frame members 2 and 6 has a keyway 29 extending longitudinally thereof and provided with slidable keys 30 secured within the hub portions 31 of disks 32. Set screws 33 or the like are provided for holding the hubs 31 against movement longitudinally of the shaft but by loosening these set screws the disks can be brought to any desired positions relative to each other. Each disk is formed with openings 34 through which extend eccentric shafts 35, these openings being largeenough to allow the shafts to rotate therein freely.

Disks 32 are located between end disks 36 secured to shaft 3 close to the frame member 2 and the free end of the shaft respectively. The ends of the shafts 35 are journaled in these end disks 36 and one end of each shaft 35 has a gear 37 meshing with a large gear 38 loosely mounted on the shaft 3. Gear 38 has a beveled portion 39 adapted to be engaged by an actuating gear 40 secured to a shaft 41 slidably mounted in a supporting bracket 42. Shaft 41 can be ro-. tated by any suitable means, such as a crank 43 and can be moved longitudinally to bring A gear 40 into or out of mesh with a gear 39. A spring 44 can be employed for holding the two gears normally outof mesh. By shifting the gear 40 into mesh with gear 39 and then rotating shaft 41, gear 38 can be rotated and will thus rotate all of the gears 37 and cause all of the shafts 35 to rotate within the openings 34 and the disks 36.

Each disk 32 has laterally extending pins 45 extending through slots 46 provided adjacent the centers of segmental plates 47. One end of each of these plates is offset laterally as shown at 48 in Figure 7 an'd the other end of each of these plates is recessed as at 49 to receive the offset portions 48 of the next adjoining plate 47. Thus the ends of the segmental plates can lap and these lapping portions are formed with openings 50 and 51 respectively through which the eccentric shafts 35 extend. Each segmental plate has its outer marginal portion widened to form a rim 52 and these rims have upsetting plates 53 attached to them. Two or more longitudinal grooves 54 can be provided in the outer surface of each plate 53, these grooves constituting means for clinching the ends of staples driven into the grooves. On some of the segments the plates 53 extend across and laterally beyond the peripheries thereof. On. other segmental members 47 longitudinal recesses are provided as shown at 55 in which are secured upsetting plates 56. v

By mounting the segments 47 as described it will be apparent that the rotation of the eccentric shafts 35 will result in the bodily movement of the segment inwardly or out wardly to collapse or expand the barrel form or drum. As shown particularly in Figure 5 the openings 50 and 51 are peculiarly shaped so that the rotation of a cam shaft therein will first move the end of one segment 47 inwardly after which the near end of the other segment 47 will be moved inwardly. By having-the rim portions of the segments projecting to form'tongues 57 it will be apparent that it is thus possible to draw one segment inwardly relative to the tongue after which the other segment will be drawn inwardly so that the ton e will be brought to lapping position as s own in Figure 6. Reversal of the rotation of the shafts 35 will reverse the'movement of the segments. Thus a quick collapse orexpan-- 35 between'their'ends, each of the shafts is.

extended through a roller 58 concentric with the axis of rotation of the shaft. These rollers engage and are adapted to travel 3 by one of the keys 30 and having its periphery concentric with the shaft. By mounting the intermediate portions of the shafts 35 in this manner said shafts are constantly held properly supported so as to resist the actions of 'the stitching mechanisms.

Supported longitudinally of the machine, parallel with shaft 3, is a shaft 60 mounted in bearing blocks 61 slidably supported within the frame members 1,2 and 5. A pressing roller 62 is carried by this shaft between the frame members 2 and 5 and a gear 63 is also carried by the shaft and constantly meshes with a. gear 64 secilred to the shaft 3. The bearing blocks are yieldingly supported by springs 65 hearing against shiftable blocks 66 and engaging these blocks 66 are cams 67 carried by a shaft 68. A crank arm 69 or the like can be used for rotating shaft 68, thus to raise the bearing blocks relative to shaft 3 or allow the blocks to move away from the shaft. The movement produced in thismanner is very slight and will not be sufiicient to interfere at any time with the proper meshing of the gears 63 and 64.

Pivot-ally connected to the frame members 2 and.5 are levers 7 O in which are journaled trunnions 71 rojecting from the ends of pressing rolls 2. These trunnions are engaged by spring pressed bearing blocks 73 slidable in the levers.

One pair of levers 70 located at any suitable point supports a shaft 74 on which are adjustably mounted rollers 75. adapted to rotate in the same planes with the-disks 32 and the segment carried thereby. By providing spaced rollers on one of these shafts, 74, suflicient clearance space is provided for a bracket 76 slidably mounted on a guide 77 suitably connected to the frame members 2 and 5. This guide may consist of parallel rods as indicated in Figure 1 and the bracket 76 can be secured in any desired manner to the rods after it has been adj usted to a predetermined position. A shaft 78 is journaled in bracket 77 and is provided at one end with "a cutter head 79 while its other end may be provided with a belt-wheel 80 whereby the shaft can be driven continuously at a high speed by a motor, not shown,or any other suitable drive element. The cutter head 79 is located adjacent the around a bearing disk 59 held to the shaftdisk 32 nearest frame member 2 where it will engage and chamfer the barrel stock at one end soas to flare the inner surface of said end to facilitate the insertion of a barrel head during the closing of a barrel 7 after being filled.

All of the levers are slidably and pivot. ally connected at 81 t0 rings 82. These rings are connected by rods 83 to straps 84 mounted on eccentrics 85 secured to a shaft 86. This shaft is adapted to be rotated by means of a lever 87 or the like whereby the two rings can be rotated so as to simultaneously swing all of the levers 70, thereby to move all of the rollers 72 and 75 toward or from the disks 32.

As shownparticularly in Figures 3 and 5 the roll 62, which constitutes a feed roll is located beneath the disks 32 and close to an endless feed table. This feed table includes spaced pairs of sprockets 88 on which are mounted endless chains 89 adapted to move over a support 90. The outer sides ofthe side chains are formed with outstanding abutment ears 91 extending from the respective links and these ears are adapted to travel under retaining brackets 92 extending from the sides of thesupport 90. At regular intervals apart the links j of the chains are provided with transverse pins 93 95 mountedfor rotation,- each pin being jour-' naled within the car 91 of the link and also wardly on this fin er so as to hold'jaw 95 barrel former and there are located on the support 90 tripping lugs 100 spaced apart a distanm equal to the distance between every two adjoining fingers 98. The brackets 92 are located adjacent these lugs 100 so as to' prevent the chains from lifting off 1 of the support'90 when the fingers 98 ride over the lugs 100.

' A crank arm 101 may be connected to the shaft 102 on which one end portion of the feed table is mounted and by means ofv this crank the feed table can be actuated.

Each of thelinks of the chain has one or more side ledges 103 and to any of these ledges may be connected stave supporting springs 104'the free ends of which have upstruck ears 105. Each spring can be curved as shown in Figure 12 so as to overhang the fastened end thereof or, if 'preferred,'each' spring can be extended away from the at-\ tached end as shownin Figure 13. Springs of different shapes are provided so that they [can be adjusted accurately to properly engage staves of veneer of different standard widths. The ledges 103 are formed with longitudinal slots 106 and the springs can be adjusted along these slots, as will be obv ous.

That portion of the endless feed table supported close to the feed roll 62 is overhung by a deflecting plate 107 and it is to be understood that other deflecting plates 108 can be located wherever desiled to prevent the advancing ends of the stock from becoming hung on any portion of the machine during the formation of the barrel.

Hingedly connected to the frame member 5 is a cross head 109 having any suitable means, such as a latch 110 for holding it in position across the opening 4 formed within the frame member 5. A stubshaft 111 is journaled within the cross head 109 and extends from the center of a disk 112 in the periphery of which is formed an annular recess 113 provided with an-upsetting plate 114. The cross head 109 is adapted to be swung outwardly to leave the openings unobstructed and thus allow a completed barrel to be removed from the inachine through the opening. Short prongs 115 are provided at the free end of shaft 3 and are designed to engage and hold a barrel head when thrust against the end of the shaft.

Slidably mounted on that portion of the shaft 3 between the frame members 1 and 2 are collars 116 and 117. The two collars are connected by links 118 and an actuating lever 119 is pivotally connected to the collar 117 and adjustablv and pivotally connected to a bracket 120 extending from frame member 2. Diverging arms 121 are fixedly connected to and extend from collar 116 and have parallel portions 122 slidable within I the frame member 2. The free end of each of these portions 122 has a head 123 and the heads are spaced apart diametrically a distance slightly greater than the diameter of the drum when collapsed or, in other words, this distance between the heads is substantially equal to the diameter of the barrel when formed. Consequently longitudinal movement of the arms will result in the shifting of the former barrel longitudinally along the drum and into and through the opening 4. Actuation of the heads 123 is effected by shifting lever 119 and causing it to pull through links 118 upon collar 116. When it is intended to use the machine herein-describedthe disks 32 are adjusted along the shaft 3 so that the segments carried thereby will be properly located to engage the formed barrel where the stitching operations are to take place. The sprockets 88 are also adjusted relative to each other so as'to properly engage and hold the hoop strips H. Springs 104 are adjusted to support the veneer staves Sas shown particularly in Figure 5, the forward side edge of each stave resting on the. adjacent ears 105 while the rear edges of the staves extend under the adjacent ears 105 and rest on the free ends of the springs 104. Thus the staves will he supported in lapped relation by the springs of the endless feed table and will extend over the hoop strips H. The back ends of the hoop strips extend under and are to be gripped by one set of jaws 95, as illustrated in Figure 15, these strip ends projecting rearwardly beyond the staves. The ends of the staves abut against the ears 91 and are thus held in alinement. The upper portion of the endless feed table is preferably of such length as to allow for the placing of two or more groups of stock, the stock of each group being sutlicient to make one complete barrel exclusive of the heads.

After the stock has been assembled as described the crank 101 is rotated so as to move the upper portion of the feed table toward the drum. This movement will be sufficient to carry fingers 98 away from the tripping lug IOOadjacent the outer end of the supporting structure 90. Thus the jaws 95 will move downwardly under the action of the springs 99 and grip the hoop strips thereunder as shown in Figure 15. This movement will also bring the advancing edge of the first stave and the front ends ,of the hoop strips between the roll 62 and the segments 47 carried by the disks 32. The operator then inserts liner strips L between the roll 6 2 and the segments 47 so that they will lie within the grooves or recesses 55 and 113. Tn the structure illustrated three of these liner strips are fed to the machine one of the three, however, being received by the recess in the head 112 while the others are received by the recesses 55.

It might be stated that prior to the feeding of the stock to the drum as described a circular head B is applied to the end of the drum. This is done by first swinging the disk 112 to open position. Ahead B is then placed within a circular recess 124 formed within the head 125 of an applying tool 126. The open face of this head is flared as shown at 127 and a handle 128 may be extended from the head. A plunger 129 is mounted for reciprocation in the head 125 been expanded to its maximum diameter by means of the gears 39 and 40 and the eccentries 35 as heretofore explained. This action will center the head B on the end of the are .120 and has a stem 130 slidable in the handle,

I aeeaeeo drum and by then thrusting plunger 129 violently against the center of the head B said head will be driven onto the prongs 115 which will thus hold the head B to the drum. 'The applying tool is then removed s and the cross head 109 is swung back to position across the opening 4 so as to cause the disk 112 to clamp against the head B as shown in Figure 4. With the shock thus applied to the machine the shaft 78 is set in motion and shaft 68 is rotated so as to shift the roll 62 toward the drum and cause the stave and strip stock to be pinched between this roll and the drum. Lever 87 is actuated to swing levers 70 so as to position the rolls 72 close to the drum. The operator 'now Shifts lever 14 'so as to couple gear .12 to shaft 11 and thus transmit motion to shaft 3 and cause the drum to rotate As both the :0 drum and the roll 62 are driven positively the stock pinched therebetween will be fed between the drum and the rolls 72 until the advancing edge of the first stave is brought to position under the stitching mechanisms.

Z5The operator then uncouples gear 12 from shaft llhthus stopping'the rotation of the and the stitching together of the strips and staves will take place during the pauses in the rotation of the drum. It will be noted that the liner strips L and the hoop strips H are so positioned relative to each other that the same stitches will pass through them and through the staves. The upsetting plates located in the grooves in the seg- -ments 47 serve to clinch the fastening means.

The liner strips are, longer than the circumference of the formed barrel and are designed to lap at their ends during the com-- pletion of the forming operation, these lap-.

- ping ends being stitched together during the stitching of the other parts. .Two of the liner strips will be positioned at opposite sides of the head B as shown in Figure 4.

It is to be understood that when the drum and roll 62' start to pull the stock into the machine motion is transmittedthrough the stock to the endless feed table which is thus actuated in thev direction indicated by the arrow in Figure 9. As the laststave of the asembled stock passes between the drum and theroll 62 the fingers 98 of the jaws 95 gripping the hoop strips of the assembled stock will pass onto thetrip ing-lugs 100 nearest,the drum. Thus the Engers98 will be lifted and jaws 95 moved out of engagement with the hoop strips B. .This results in the disconnection ,of the stock from the table and the table will be brought promptly to a stop. The table will remain stationary during the completion of the rolling of the barrel and while said operation is taking place some additional stock may be assemled on the table preparatory to being fed toward the drum; After the rolling of the barrel has been completed the operator shifts lever 20 so as to disengage gear 17 from shaft 16. This will stop the actuation of the stitching mechanisms and the rotation of the drum. The operator then lowers roll "62 by turning crank 69 and also moves the rolls 72 away from the formed barrel by shifting lever 87 as heretofore described. Following this operation the disk 112 is swung away from the opening 4 so as to leave it unobstructed. By means of the gears 39 and 40 the eccentric rolls 35are then aptuate'd to collapse the drum throughout its circumference as shown in Figure 6; Lever 119 is then shifted so as to thrust the heads 123 against the end of the formed barrel whereupon said barrel will be pushed thr'ou h the opening 4 and can be removed readi y from the drum.

Following the removal of the barrel the foregoing operation can be repeated, the drum being first expanded to its maximum diameter, a head B clamped against one end of the drum, the rolls 62 and 72 properly positioned relative to the drum, the stock directed into engagement with the drum and the roll 62, and the-mechanism then set in motion.

It might be stated that during the rolling m I of the drum the rapidly rotating cutter hea 79 will chamfer the inner surfaces of the staves at the open end of .the barrel so that a head c an be inserted readily into the top of the barrel after it has been filled.
