Patented Apr. 7, 1931 UNMED srArss leraar OFFICE EDWIN F. BEUGLER, OF BUFFALO, NEW YORK, .ASSIGNOR TO E &: B HOLMES MA- CHINERY CO., OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK BARREL-MAKING- MACHINE Original application led''anuary 31, 1927, Serial No. 164,676. .Patent No. 1,723,838. Divided and this application f le May 29, 1929.

This invention relates to a machine for making slack barrels having a body c omposed of an annular row of longitudinal staves, each of which tapers toward its opposite ends, so that the completed barrel has a bilge midway of its length, and the several staves being held together by surrounding j hoops. 1

It is the obj ect of this invention to provide improved means for driving the hoops on the body or shell of the barrel.

This is a division of application No. 164,676, filed January 31, 1927, now Patent Aline 2-2, Fig. 1. Y

Y' ing rope and then loosely applies permanent Figure 8 is a fragmentary horizontal section taken on line 3 3, Fig. 4f.

AFigure 4 is a fragmentary vertical section taken on line 4 4, Fig. 2.

Figure 5 is a fragmentary vertical section taken on line 5 5, Fig. 1.

Similar characters of reference indicate corresponding parts in the several figures of the drawings. Y

The' staves 50 of this barrel shell or body are tapered from their central parts toward their opposite ends, similarV to those now'commonly employed in slack cooperage, and these are temporarily held together adjacent to the bilge andfthe ends of the shell by bilge and end hoops 107, 106 respectively.

, After the upper ends `of the staves of the barrel have been drawn together or con tracted bythe windlassing mechanism so that the shell or body of the barrel is of substantially tubular form, but having a bilge in its center, the operator places another temporary or trussing end hoop ,106 on this end of the shell before releasing the windlassbilge hoops 107 upon opposite ends of the shell or body adjacent to the bilge thereof.

Serial No. 366,899.

The shell having the temporary end hoops and lthe permanent bilge hoops applied thereto is then placed in an upright position with one endV resting on the main base 75 in proper position relative to the hoop trussing or driving mechanism which is constructed as follows:

V Arranged above that part of themain base supporting the barrel to be trussed is a vertically movable cross head 108 which is secured on opposite sides to the upper ends of two vertically movable gear racks 109. The latter are guided at their lower ends 1n pedestals `110 which rise from the main base on,

opposite sides of the barrel bodyor shell supported on the base. These gear racks together with the parts vmounted thereon are caused to rise and fallby a lifting mecha- Vnism of any suitable construction.

The mechanism whereby the trussing or driving of the bilge hoop is effected is constructed as follows:

The numeral 156 represents a plurality of upright driving arms which are arranged in an annular row around the cross head 108 and each of which is pivoted thereto` at its opposite end by meansof a horizontal pivot bolt 157 so that the driving die or jaw 158 at the lower end of each driving arm may be moved toward and from the periphery of the barrel shell or body, and into and out ofengagement with the upper edge of the upper bilge'hoop. The several driving arms are moved inwardly preparatory to engaging with vthe bilge hoop during the descent of the main cross head by means of a rotary crank disk 159'journal`ed to turn about a vertical sleeve 160 mounted vertically in line with the axis yof the barrel shell when the ,v

same is in its normal operating position on the main base 75.

This crank disk is provided with a plurality of crank pins 161 each of which is coninected with. the inner end of a shifting'rod,

162. The outer end of V'each shifting rodis yieldingly connected with one ofthe driving arms below the fulcrum of theflatter by slidingly engaging the outer part 4of each rod 162 with its guide lugs 163 on the respeci-ive driving arm, and interposing a spring 164 between the inner guide lug 163 and the inner side of a collar 165 on the respective shifting rod, as shown for example in Figs. 1 and 2. In Fig. 2, the crank disk 159 is shownby full lines at one extreme of its turning motion in which the driving arms 156 are expanded or moved outwardly. Upon turning the driving disk 159 by means of' a handle 166 into the position shown by dottedlines in Fig.' 2, the several crank pins 161 on this disk will cause the shifting rods 162 to draw the driving arms 156 inwardly Vand engage the periphery of the barrel immediately above the upper bilge hoop thereon.

Such. inward movement of the several driving arms is limited by providing the main cross head 108 at' one or more points on itsperiphery with a stop 167 adapted to be engaged with the adjacent driving arm 156 as.` shown in Fig. r1`he driving arms are yieldingly held either in the outer inopera tive or in the inner operative position by means of a retaining device consisting of a retaining dog 168 adaptedto be engaged with oneY or theother of two notches or seats 169 and 1.70' arranged circumferentially on the adjacent part of the cross head, said dogbeing. arranged in a tubular arm 171 mounted to turn with the crank disk 159 and held yieldingly in a. projected position by means of a. spring 172 arranged in the tubular arm 171v and bearing at its' opposite end against the retaining dog 168 and the bottom of this tubular arm, as shown in Figs. 2 and 5.

After the operator has turned the crank disk 159 so as to shift the driving dies or jaws into the proper position relative to the periphery of the barrel, the operator works the lever 133 so as to cause the main cross head to descend whereby the dies or jaws of the driving arms are caused to engage the upper edge of the bilge hoops and drive the same downwardly on the shell or body of the barrel until it is tight, after which the operator reverses the throw of the crank disk 159 and causes the driving dies or jaws 158 to be disen @aged from the bilge hoop. Thereafter the operator again manipulates the controlling lever 133 so as to cause the main cross head to effect the second and final part of its downward movement for the purpose of engaging a driving ring or flange 17 3 with the upper edge of the upper temporary or truss hoop, as shown in Fig. 1.

This driving ring is formed on the inner lower part of a circular rim 174 which is secured to the underside of the main cross head 108. During the last step of this descending movement of the main cross head, the upper end of the barrel is centered by engagement therewith of a plurality of downwardl diver inO centerino' iiners 175 seo b n cured to the lower edge of the supporting rim 174 and adapted to engage with the upper peripheral edge of the barrel shell or body, as shown in Fig. 1. During the final portion of the downward movement of the cross head, the driving arms and the driving dies or jaws at their lower ends are disengaged from the adjacent bilge hoop and move idly downwardly beyond this hoop as shown in 1, so that only the driving ring 173 at this time performs any function.

Afterl the bilge and end hoops have been driven on one end of the barrel shell the latteris reversed end for end and similar operations are performed onthe other end of the barrel shell which is now uppermost, while the reversed finished end is now resting on the main base of the machine.

Any suitable means can be provided for centering the barrelshell relative tothe hoop driving mechanism.

For the purpose of permitting driving heads or rims 174 having driving rings 173 of dirl'erent diameters to be employed for operating on barrels of different sizes or diameters, and permit of ready substitution of one driving ring 173: of one diameter for that of another diameter without disturbing the axial alignment, the following means are provided for connecting the head or rim 174 of the end hoop driving ring with the cross head and adjusting these parts relatively to each other.

Projecting laterally from opposite sides of the driving head or rim 174 are two adjusting arms 275 each of which is provided with a circumferential slot 276 and a vertical open ing 277. Above each of these arms the cross head 108 is provided with a supporting arm 278 which is connected with the respective adjusting arm 275 by means of a bolt 279 passing through a radial slot 872 in the arm 27 8 and the slot 276 of the arm 275, as shown in Figs. 2, 3 and 4. Each of the supporting arms 278 is also provided with a downwardly projecting tapering centering pin 280 which ,enters the opening or eye 277 in the adjacent adjusting arm 275 of the driving head, as shown in Figs. 3 and 4.

Mounted in an annular row around each opening 277 on the respective adjusting arm 275 and preferably at different quarters of the circle are three radial adjusting screws 281 which bear against different parts of the periphery of the centering pin 280 and are held in their adjusted position by means of clamping nuts 282. In mounting the driving head on the carrier or cross head 108, this head is first loosely connected by means of the bolts 279 of the arms 278 with the carrier or cross head. rlhe driving head is then adjusted circumferentially as well as radially in the proper direction for bringing the driving ring 173 into the proper axial alignment with the shaft 176 of the cutter mechanism, which is eiected by turning the screws 281 in one di- Cil rection or the other while the same are inv engagement with the centering pin 280.

After the parts have been properly aligned, the bolts 27 9 arel tightened so as to maintain these parts definitely in this relation. If now it is desired to remove the respective driving head 174 from the cross head and replace it by another driving head adapted for a different diameter of barrel, it only is necessary to remove the bolts 279 in order to release the respective driving head without however disturbing the adjustment of the radial bearing screws 281 relative to the centering pin 280. v This permits this driving head to be again replaced on the cross head by simly slipping the openings 27 7 of the adjusting arms 275 upwardly over the centering pins 280 and then applying the fastening bolts 279 and thereby bring the parts together again in axial alignment without the necessity of any re-adjustment, whereby changes in the machine for operating on different diameters of barrels can be eiected easily and quickly so that a considerable saving in time and cost of production is effected.

By constructing the centering pins 280 of downwardly tapering form it is possible to easily remove the driving head from the cross head, inasmuch as the adjusting screws 281 will readily disengage themselves from the centering pins 280, due to the tapering form of the latter, and re-engagement of the same is equally easy. This, however, would not be possible if the centering pins 280 were of cylindrical form, inasmuch as the adjusting screws 281 would have a tendency to bind on the centering pins 280 both when assembling the parts or dis-membering the same in case the driving head is tilted slightly out of its level position during this operation.
