BARREL-MAKING MACHINE.

Application filed September 12, 1921. Serial No. 500,142.

The invention relates to barrel-making machinery and more particularly to a machine for heading up wooden barrels and for removing form or trussrings used in the manufacture of the barrel.

In the making up of barrels, particularly heavy barrels for containing liquids, it is customary to assemble the staves, in the earlier process of manufacture and seasoning, within heavy iron or steel truss rings or hoops including a hoop at each end of the barrel and a pair of bilge hoops around the center portion of the barrel. In the final process of manufacture it becomes necessary 'to re move these temporary form rings and substitute therefor the ordinary barrl hoops, and by reason of the tightness required in the joints between the staves and the stress occurring in the bending of the latter, the truss rings are driven on with great force and are difficultto remove for the substitution of the ordinary hoops.

It is an object of this invention to provide a machine by which the end portions of the staves about the compressed sufficiently to permit the ready removal of the truss rings and their replacement by permanent hoops.

It is a further object to provide for the simultaneous dislodgment from the center portion of the barrel of the bilge truss rings.

A further object is to so construct the operating parts as to permit the emplacement and removal of thebarrels from the machine with great facility and economy of time and effort.

A further object is to provide a machine for the purposes described which 1s of a very simple and durable construction, and adjust ably adapted to operate upon barrels of vari" ous sizes with equal facility. I

Other objects and advantages Wlll be apparent in the following descrlption of a preferred embodiment of my invention which I a have illustrated in the accompanying drawings.

Referring to the drawings, Figure 1 represents a plan view of the complete machine. Fig. 2 represents a rear elevation of the machine. Fig. 3 represents a side elevation and Fig. 4 a fragmentary sectional view of the clutch and driving mechanism. v

The frame of the machine may be variously constructed, but in my' preferred embodiment head of the barrel may be 1 I have illustrated a main frame having a base 1 constructed with lateral upright portions 2 upon which latter are mounted a pair of upright standards 8. The upper ends of the standards are formed with L-shaped rear ward extensions 4 in which latter is horizontally'pivoted at each side a head frame 5. The pivots are located in the head frame structure a substantial distancerearwardlv of the center portion thereof, which permits the front portion of the head to be swun upwardly. When in horizontal position th: head frame 5 rests forwardly ofits pivots upon the upper ends of the standards?) as at 6. i Located centrally betweenthe upright por tions 2 of the base is a horizontal table 7 which may be mounted with any suitable means for raising and lowering the level of the table, as by hand screws 8. The table 7 18 adapted to receive a barrel standing on end and extending upwardly through the head rame 5 when the latter is in lowered positron, the upper end of the barrel bein in position to be grasped by clampin devices hereinafter described. b

The swinging head frame 5 carries on' its upper surface a plurality'of clampingqjaws,

of which I have illustrated herein the three aws 9, 10 andll mounted in ways on the head frame and arranged to slide radially to and from the center of the opening in the head whereln the barrel is received. The inner faces 12 of the clamping jaws are formed with circular peripheries of a suitable'radius to effect substantially continuous 'fcontact with the barrel being clamped thereby.

Tn my present embodiment one ofthe jaws 9 is adapted to be manually moved on its radial ways by means of-an eccentric 'pin 13 having its lower portion .14 journaled in the head frame and an eccentricportion 15 operatively extending through a transverse slot bearing 16 in the jaw 9. Thejaw' 9 thusmay be withdrawn to clear the opening in the head frame when placing a barrel to be operated upon. A handlef 16 is provided by which to rotate the pin.

The other two jaws 10 and 11 are also radially slidable in similar ways 17 formed in the upper surface of the head frame 5, and

are positioned with respect to each other and,

the jaw 9 so that their inner peripheries when normally closed. ointly describe circle cf Inn till

cross-head is connected at each side with the respective outer ends of the rockers 18 by means of longitudinally adjustable con necting rods 22, the rod connections both with the cross-head and with the. rockers being pivoted. The connecting rods 22 are so arranged in relative position that by the inward movement of the cross-head 20 a powerful toggle action is produced which operates the rockers to force the jaws 10 and 11 inwardly upon the barrel end supported within the head frame 5 and rigidly held by the third jaw 9.

For the operation of the toggle mechanism I have provided power transmission means comprising a pair of inter-geared driven shafts 23 and 24 having their. bearings in the lateral upright members 2 of the base, with their ends extending outwardly therefrom, and one of which carries a suitable cam mechanism for the operation of a rocking lever which actuates the cross-head 20. More particularly described as illustrated in my preand drives a gear 26 fixed on the outer end of the other shaft 23 which'latter carries .at its opposite outer end a fixed pinion 27 meshing with a gear 28 fixed on the shaft 24.

The arrangement of gears and shafts here described is to provide suflicient gear reduction in most compact form to give the desired power for the eflicient operation of the jaw operating mechanism. The shaft 24 is further supported by intermediate bearings provided in a pair of upright bearing supports 29 formed integrally with the base 1.

Fixed centrally upon the shaft 24 between the bearing supports 29 is a cam member 30 of which the operative periphery is in contact with a roller 31 carried by an upright rocker arm 32 centrally pivoted upon a rocker shaft 33 carried in bearings 34 formed in upward extensions of the two bearing supports 29. The upper end of the rocker arm 32 extends rearwardly and in operative contact with the cross-head 20 of the toggle mechanism. The arrangement of the rocker arm and cam is such that with each revolution of the cam the rocker arm is actuated to force the crosshead 20 inwardly to close the clamping jaws.

Operative contact between the cross-head and the upper end of the rocker arm may be accomplished through a cushioned driving head 35 which is positioned in a recess 36 in the end of the rocker arm and which latter carries therein a compression spring 37 adapted to cushion the force of the inward. movement of the rocker arm. A stem 38 upon the head 35 extending through the rear wall of the recess, is engaged by a retaining nut 39. The contacting faces of the driving head 35 and the cross-head 20 are arranged so that the head frame 5 may be swung 011 its pivots whereby the rearward end of the head frame carrying the toggle mechanism is dropped downwardly out of contact with the rocker arm.

The mechanism for removing the temporary bilge hoops from the barrel whenp'ositioned on the platform or table 7, includes a pair of slideways 4O vertically positioned and preferably formed on the inner surfaces of the inwardly projecting portions 41 of the two standards 3. Operating therein respectively are a pair of slides 42 each carrying at its lower end a pair of pivoted links 43 connected to the outer end of one of a pair of horizontal rocker arms 44 centrally bearing and supported on the shaft 23.

rocker arms 44 extend rearwardly carrying at I their respective rear extremities rollers 45 having operative contact with the peripheries of a pair of cam members 46 fixed on the shaft 24 and which are arranged to actuate the rocker arms and vertically reciprocate the slides 42 in their respective. ways.

On the inner faces of the slides 4 are mounted in each instance av bracket 47 suitably secured for vertical adjustment of position upon the face of the slides as by means of bolts 48 and a series of bolt holes 49. Pivoted to each of the brackets 47 is a depending dog 50 normally actuated to swing inwardly by means of a compression spring 51. carried by a bolt 52 mounted in the bracket and far ranged to effect compression of the spring by the outward swing of the dog. The lower ends of the dogs are eachformed with a notch or shoulder 53 suitably arranged to engage a bilge truss ring or temporary hoop carried by a barrel being operated on as illustrated at 54, and with the downward movement of the slide to force the bilge ring from the barrel.

The several cam. members operating the clamping jaws and the truss ring removing dogs, are preferably in such relation that the downward movement of the dogs occurs simultaneously with the inward movement of the jaws, and likewise with the opening of the jaws, the dogs are returned to their initial position.

The

lil

In order to control the operation ofrthe V clamping jaws and ring removing mechamsm, I have provided a clutch mechanism all which preferably comprises the arrangement illustrated in Fig. 4., The loose pinion is formed with an integral sleeve extending outwardly along the shaft 24 and abutting the inner surface of the hub of a pulley 56, the latter also being mounted for free rota tion upon the shaft 24. The pinion and pulley are secured in longitudinal position by means of a collar 57 suitably fastened at the outer end of the shaft 24, the inner surface of the pinion being confined against opposite movement by the outer faceof the adjacent shaft bearing. The inner face of the pulley 56 is provided with a cone shaped re-- cess 58 with which is associated a cone clutch 59 of well known construction, which is carriedby a sleeve 60 slidably overlying and splined upon the inner sleeve 55. The clutch and its carrying sleeve may be moved longitudinally into driving engagement with the pulley by means of a shifting bar 61 having suitable means to emb ace the leg of the operator standing before the machine, preferably constructed as illustrated at 62, and adapted to operate the lever 63 pivoted on the main frame. The latter operates through the pivot pin 6a a shifting lever 65 formed with a yoke embracing the sliding bar 66 which carries at its outer end a yoked element 67 carrying pins suitably positioned to enter in rotative engagement an annular slot 68 formed in the clutch sleeveGO. By'a movement of the operators leg the clutch mechanism is thus conveniently thrown into and out of engagement.

In operation, the head frame 5 is thrown upwardly, a barrel is placed on the table 7 in upright position as illustrated in Fig. 2, and

the table adjusted to the desired height,

whereupon the head frame is swung downwardly with the barrel extending through the central orifice of the frame with the end truss ring clear of the clamping jaws. The machine is then put in operation until the jaws are securely clamped about the upper end of the barrel whereupon the clutch is released and the end truss ring removed from the barrel while the staves are so compressed. A permanent hoop may then be placed on the barrel and the machine again put in operation to complete the revolution of the cams and release the clamping jaws. Simultaneously with the closing of the jaws the lower bilge ring has been struck from the barrel.

It will now be apparent that I have provided a readily operable and efficient means for replacing the truss rings with permanent hoops with convenience and economy. While I have illustrated and described in detail the preferred embodiment of my invention, it should be understood that in the interpretation of the appended claims it is not intended that they are to be limited to the precise construction and arrangement therein contained as many variations and modifications will naturally occur to those skilled in the art.
