My invention relatesto barrel forming machines and more particularly to that type of machine wherein the barrel is forme from aplurality of staves held together by t 5 hoops or bands. 1 a V V I An object; of this invention is. to provide a barrel forming machine wherein the staves may be readily placed in proper formation and securely held until hoopsor other 1e Furtherthe invention-provides a barrel "forming machine embodyinga collapsible form or mandrel whereby the completed barrel body may be removed with facility '3 115 and ease, the form or mandrel being manually collapsible for. this purpose. T 1

,Still another object of the invention resides in the provision of a barrel forming vJnandrelyvhich is rotatable step by step to 20 facilitate placing of the staves thereon.

With the preceding and other objects and advantages in mind, he invention consists inthe novel combination of. elements, constructions and arrangements'of parts to be claimed and illustrated in the accompanying drawings, wherein:

Figure 1 is a chine; H V

Figure 2 is a rear elevation of the same;

a Figure 3 is an end elevation; 5 a

Figure a is a view similar to. Figure 3 but showing the reverse endof the machine; and Figure 5 is a transverse sectional veiw 35 taken on line 5-+-5 of Fig. 1. l

Referring to the invention in detail a rectangular frame 5 is provided which ineludes vertical supportinglegs 6L, A collapsible or barrel formv is provided front elevation of the ma- 1 4 which includes a shaft 7 extending longitudinallyand horizontally within the frame .supportedin bearings 8. As illustrated a 1 and '4, the forward endofthis I shaft carries a spider?) of crucifonncon-l figuration having pairs of parallel arms 9.

in Figures the ends of posit/e tangular body 20 which in turn is rigidwith and projecting laterally To support barrel st form a barrel, a series of transverselycurved and longitudinally bowed segments 10 havmg normally abutting bevelled. longitudinal edges 11 as illustrated in Figure 15, extend circumferentially around the shaft. 7 At their forward ends-each of the segments s formed with a pair of parallel armed-2 whlch convergetowards the front edge ofthe shaft and are pivotally connected tothe paral- .lel arms of the spider by pivot ,pins 13 passmg through each pair of the latter arms and the arms 12. I

For the purpose of collapsing the .form a pairof H-shaped lGVGISIll, eachqdisppsed upon opposite sides of the shaft intermediate the segments, are-pivotally; connected together jat'their inner endsby' means of a pivotalelement 16;and to a collar=21 which is engaged-by a yoke by whichitis sl1d on the shaft' The outer ends of thes levers are pivotally connected with parallel ears 17 formed upon the inner faces ;of two diametrically opposite segments, 4 j

. To shift the yoke to collapse :the form nhorizontally disposed hand-lever 18 is pivotally mounted upon a laterally projecting bracket 19 attached to the frame adjacent One ,end thereof. An longitudinally .of the form has on end pivactuatingrod 1;.9' extending {I5 otally connected to the hand lever-and its opend operatlvely connected with {8 recthe yoke 15. 7 a

- Disposed upon opposite sides cf the shaft from the inner face ofthe other pair of diamet,rically opposed s g s are ted brackets 23 which receive oppositely extending stop .rblades 24 projecting from the collar 21.: A pair 'fiflpfl'lfllleli contractile springs 25 are connected to this pair of. diametrically opposed segments :and r a ly r he latter together It will be observed that, henzthe form isnollapsed the .endwalls' of the slotted brackets gamm -1 aves in ,position to the ends of the stop blades will limit the inward movement'of the resiliently connected pair of segments. Y

The invention contemplates means for temporarily securing staves from which the barrel is formed to the form hoops have been placed on the staves. This means consists of a shaft 29 extending lon-.

gitudinally of the form and journalled in bearings 30 one one side thereof and carrying pulleys 31. which-are located at the ends of the form. A crank handle 32 is carried by :one end of the shaft for rotating the latter while-a ratchet wheel 33 is also fi-xed to this end of the shaft and held against rotation in one direction by a pawl 34 projecting laterally from the frame. Flexible elements 35 the -ments 38 carry'weights 40 at oneend while *In'this connection, it v regardless of the size of the form or the thick-v ness' of thestaves', the always be maintained infeng'ag'ement with 'the under side of the Y placed-thereon.

are attached to the rear side of the frame below the form as at 3'6, and are extended circumferentially about each end of the form to engage the endsof the, stavesrplacedthereon, then wound about the pulleys 31 and final- 1y fastened to said pulleys. A second pairof flexible elements 38 are trained over pulleys '39 mounted upon the upper face of the frame at the rear thereof at points equidistant from ends of the form. These flexible eletheir opposite ends aresecuredto a channel shaped securing bar/41 adapted to be received on the' upper endsof angle brackets 42"a'ttached to the upper face of'the frame.

The flexible elements 38 extend from the cha'nnel'bar 41-downwardly under the form 'an'dlthen upwardly over the pulleys 39 and are maintained in engagement'with the form by the tensioning effect of the weights 40. will be observed that flexible elements 38 will form orwith the staves Barrel staves, before assembling to provide a barrel, are perfectly flat and to bow these staves transversely while onthe form, a die '44'is provided. This die comprises a pair of longitudinally curved arms 45 connected intermediate their ends by a bar or brace 46. As illustrated in Figure 4, these arms extend transversely of the frame and have their rear ends "-t'ached to the frame.

pivoted to brackets 47 at- A hand leverf48 also pivotally mounted on ertmgmanualdownpressure upon the hand glever 48.

Forthe purpose'of correctly positioning the staves on' the form, an upwardly extendinglongitudinally curved gage, element '01 blade 50., attached to the until the securing,

,have been previousl staves until hoops the frame adjacent the bracket 47 I is rigidly connected with the arm's-by means of straps 49. With several staves placed upon the "to bear upon the staves and shape them to the cross sectional area of the form by, ex- 4 form the 'd-ie'is brought frame, extends along the inner edge of the form against which the inner ends of the staves engage when slipped longitudinally into position.

eans is provided for rotating the form step by step to expose an uncovered area of the same at the top, so that the staves can be laid on the form said means comprising a. ratchet wheel 51 fixed to one end of the shaft 7 and engageable by a pawl or hook 52 formed upon the upper end of a vertically movable lever 53, the latter being pivotally connected to an arm 54fixed to a'horizontally extending rock shaft 55 'journalled in the frame. A treadle or foot engaging element 56 fixed to the rock shaft is provided for 'moving the lever 53 downwardly to successively engagethe teeth of the ratchet wheel and A contractile end connected with the thereby rotate the former. spring 57 has one lever 53 and its opposite end connected with the frame 5 for normal to raised position. i r With my invention it will be observed that the staves are retainedon the form of a barrel by means ofthe flexible element passing around the staves until manent fastenings are slipped over the staves and secured. T The flexible elements aren'ow disengaged by slackening the sameandthe form then collapsed to permit the complete article "tobe' removed. i

V In the operation of the yreturnin'g'lever staves are successively laid on the format that sideneare'st the angle bracket 42. As '100 each stave is placed'on the form it is'rota'ted a partial revolution and the next stave laid in place. As the formis rotated the staves are held between the flexible'elements 3 8 and hoops or other permachine the barrel the periphery of the form. It will 'befobserved that it will be unnecessary to hold the staves on the upper portion of the drum or that partnot embraced by the cables 38 as they will lie in place. The cables 35, which slipped off the ends of thedrum'are now s ipped back onandthen drawn taut by-rotation of the handle 32.

These cables 35 securely holdFthe ends ofthe form and secured desired to removethe completed barrelthe have been inserted on the to the staves. When it is members 41 are disengaged from the brackets 42 to allow the cables 38 to depend and the cables 35 slackened'and slipped over the ends of the'drum. The form'is then collapsed and e the barrel slipped longitudinally therefromQ 7 What is claimed is: x e

In a barrel forming machine, asupport, a collapsible mandrel supported thereon, a

plurality of flexible elements underlying the. fmandrel, pulleys supported to'one side of the mandrel and over which one end "the" flexible elements are trained, weights attached ,to' the 7 depending ends ofsu'chvflexible elements, upstanding plates g I attached to support at the opposite slde'of the mandrel, and a'channel-shaped securing member carried by the opposite end of each of the flexible elements and removably engaged with one of the upstanding plates whereby the flexible elements take a substantial U-shaped form to constitute cradle-like temporary supports for staves placed on the mandrel, and means for securing the ends of the staves to the mandrel until hoops have been secured on such staves.

Signed at Sufiolk, in the county of Nancemond, and State of Virginia, this 15th day of October A. D. 1927.
