HfoLMEsMncHrN-v L11-The numeral l13 represents aY horizontal yisoclr shaft which is arranged transversely `in-f'rontQoithe harrelisu'pport and j ournaled in'ghearings 111 on the front ypart of themain V jira-'me or hase. On 'opposite sides of the bar- V.rel support Varearranged twol longitudinal `lifting arms` 15, each o`f which is' mounted loosely at its-.frontend on the'rock shaft 1 3 .adjacent to` the-outerside of one ofthebear-V -ings14sothat this lifting armV turns about the samexaxis as the shaftbut the arm 15 is capable of turning` with the shaft 13 kand the shaft and arm are` also capable of turni'ingindependently of each other.- ntlie rear of the lifting arms and arrangedon transversely opposite sides of the barrelfsupport are two upright gripperarms 16 each of whichis pivotally connected at itslower end i with the rear end of one ofthe lifting arms by `means of a pivotppin, screw orv bolt 117 arranged horizontally and lengthwisegrelatively tothe machine and passing through the` lower part of 'the respectivegripper arm v"and into the rear end' of the companion` lift-- ing/arm 15. .Y page with-one side oi." thebarrel for pivoty-Upon the upper endsofvhe two gripper armsr are arranged two` jaws or chucks,

which are` adapted to engage with diametri-- cally opposite sides of the bilge portion ofV the Abarrel in a directiontransversely of the machine'. 4Each of these jaws comprises a head-18 which is adapted toerig/age with a part ofthe barrel vloodyand*whichis pivot- `allyconnected With-the rearend of one of :the adjusting'rods 23, in such'inanner that f the head is eapable of swiveling on vthis rod successively applied to ythese ends bythe :midwthus'` adaptitself t'ov varyingfangular positions of the surface ot the barrel relative to this rod. The first construction of the front face oi" the supporting head isconstructed in the form of a rubber pad 19 which is connected with the head by means oi an under-cut boss arranged on the iront side of the head and engaging with an under-cut recess 51 on the backof the pad, the latter being provided on its front side with a plurality ot projections 52 in order to enable the same to obtain a firm frictional grip on the side ofthe barrel. The pivotal connection between the gripper head and the rod 23 is preferably effected by providing the rear side of the head with a recess having reduced innerI part 53 which terminates in a "ball race 54 and an enlarged outer part 55. cent rod 23 projects-into this recess oi the gripper head and is provided at its inner end with a ball race 56 between which and the ball race 454 on the bottom ot this recess an annular row of balls 57 is arranged, while that part of'this rod within the enlarged part of the recess is spaced therefrom circumferentially. By means of this construction the gripper head is journaled on the gripper rod 23 so as to rot-ate freely thereon and permit the barrel to be easily reversed while at the same time the gripper head is free to rock or swivel in all directions and thus adapt the face of this gripper head to the varying positions which the surface ot the barrel may occupy relative to the rod 23. In order to prevent the gripper head from being moved lengthwise from the rod 23 and still permit of free rotation and swiveling motion ot head on this rod a connection is provided between these parts which preferably consists of the cotter pinV 5 8 passing transversely through the gripper head and engaging with an annular groove 59 on the peripheryof the rod 23 in rcar of the ball race 56 thereof.

Means are provided for adjustingly mounting each ot these jaws on the upper part of one of the gripper arms so as to adapt these jaws to barrels of different width and diameter. The preferred means for this purpose which are shown in the drawings comprise a bracket 2O engaging with the rear side of the upper part ot' each gripper arm and provided with a horizontal transverse sleeve 21 on a separate part and a vertical slit 22 in its lowerpart eX- tending from the under side ot the bore of said sleeve to the lower end of said bracket, the horizontal transverse adjusting rod 23 arranged in the sleeve 21 and carrying at its inner end the head 18 of one of the jaws and a clamping bolt 24 passing through the lower split parts of the bracketand through an upright slot 25 in the upper part of the respective gripper arm, as best shown in Figs. 4 and 5. Upon loosening the clamp- The front lpart of the adjain the slot 25, the gripper jaw can be raised or lowered to suit the height or length of the barrel which is being coopered and by tightening the clamping bolt 24 the split parts of the bracket are closedor drawn together so as toA grip the adjusting rod 23 in the sleeve 21 and at the same time this bracket is drawnv tightly against the rear side ot the respective gripper arm, thereby holding the parts'in their adjusted positions.

The downward movement of the lifting arms and the parts mounted thereon is eftected by gravity but if desired this may be aided by spring pressure, as for example by4 preferably effected by the following means.

The numeral 29 represents lugs projecting laterally rinward yfrom the lower parts of the gripper arms and each having its inner part overhanging the adjacent part of the base and provided on its underside with a downwardly open pocket 30. vWithin the pocket of each lug 29 is arranged a buffer spring 31 which engages its upper end with the bottom of this Y pocket. Extending downwardly through the bottom of this lug and the spring therein is a buiier rod 32 which has a shoulder 33 at its upper end adapted to bear against the upper side of the lug 2S) while its lower Aend is adapted to bear against the adjacent part of the base and is provided with a shoulder 34 engaging with the lower endet the buffer spring 31. These shoulders are preferably formed on this rod `by constructing the same in the form of a bolt, the head of which forms the upper shoulder 33 and the nut of which forms the lower shoulder 34. Upon moving each of the gripper arms downwardly the adjusting rod or member 32 strikes the top of the base so that its further movement .in this direction is arrested, thereby causing the gripper arm during its continued vdownward movement with the companion lifting arm to be swungr outwardly at its upper end and thereby disengage the jaw or gripper on this gripper arm from the periphery of the barrel. This released position ofthe grippers or jaws fiom the barrel is indicated by full lines in Figs. 1, 3 and 41j j y For the purpose of moving the upper ends of the gripper arms inwardly andengaging the jawsthereof withvoppos'ite sides o ffthe barrel so that the latterv is gripped thereby.V

means are provided whichV in their preferred form are constructed: as follows:

The numerals 35 'are two vertieally swinging shifting arms which are-secured at' their front ends to the rook shaft 13'adjacent to the outer sides of the lhubs of the vlifting levers l5 'and each rovided at itsI rear end with a tappet 36 wlhichpreferably has the form of a `roller pivoted on the extremity of the respective shifting arm in anylsuitable manner. y Each of these tappets engage with a cam face 37 which is formed on the lower `part of the ou-teredge of each gripper arm. At the 'lower andV upper "extremities of thek y cam face 87 ofeach gripper arm the latter is provided with lowerl and upper stops 38, 39, which limit the vertiealmotion of therespeetive tappet which co-operates with this cam. On one part of the rock shaft 13, preferably the right hand end thereof, the same is provided with a forwardly projecting treadle 40 on which the operator of the swingingmovement of each gripper :arm

machine is adapted to'step. The `outward away from the side of the barrel is limited by engagement of a stop 41 arranged on the gripperjaws aredisengaged from opposite sides of fthe barrel, the shifting arms are lowered' and their tappets are in engagement with the lowermost parts of the cam faces 37 and the pedal 40 is in" its elevated position,

as shown in Figsl and 4.

Afterthe attendantlhas placed `a barrel in its operative position in which one of its ends engageswith the top of the 'table or platform l1 the heading-up vmachine isiirst operated for applying a head to the iupper end of! thebarrel.` Thereafter: lthe operator steps on the treadle 40 preliminary to Veffecting a reversal ofthe barrel end forrendj During the rst part of this downward'motion of theA treadle 40 the shifting arms Vare raised and their tappets'l` are oause'd to move upwardly alongthe cain -`faees 37 of the gripper arms whereby the 4latter are moved inwardly forV toward each ,otherf and "the grippers or jawsthei'eon are caused 'to engage withop osite sides of the central'r'or 1 bilge portion o lthe barrel body. vAlfter the gripper "arms have .been vmoved inward-ly to fsuch an extent during the first part .of the downward movementof the treadle: as will` produire a. firm engagement ofthe jaws'with Y' thev opposite sides of the barrel then the coni` ftinued downward movement of the treadle i will fcausethe `shifting arms r`to produce 'a lifting'eifectupon the gripper arms and lifting' arms whereby Vthe barrel will` be i, lifted with its lowered end out of engage-f,V

ment fromy the top of the supporting table. or platform 11.` The raising of the barrel at jthis time is only sufficient lto lpermit;y the l barrelto be turned by the operatorabout 'the horizont-al transverse axis of the rubber pad l9whieh is'arranged axially in line` for this purpose. A. partial turning end for end of the barrel by the operator isrepresented in Fig. 2 and when, this turning has been vcompleted so thatthe end of the barrel which formerly was uppermost is nowlowermost, then'the attendant removes his foot `pressure from the t-readle *40 soas to allow thebarrel to descend by gravity together with the gripping andv elevating mechanism f associated therewith. 'The Ibarrel is arrest- `ed init-s downward movement and engages,

its lower end with the table or platform during the first part of the downward mo tion of the lifting arms and shifting arms,

Aand'during the lastfpait ,olf the downward Tf-f motion ofthe lifting'arms and the gripper YY1arms thebu'ffer mechanism on the gripper "armsen'gage with the top of the `base 'so that `the gripper arms at this* time 4are caused to vturnen the lifting arms land move `their jawsout-wardly out of engagement from op'- 'positesides ofthe barrel. This outer movementot the'l gripper arms relatively to the `barrefbody and the descent ofthe lifting arms islimited'by engagement of thestops; 4l `on the gripper arms with the stops 42 on the lifting arms, as shown in Fig. 4.

The `downward movement of the shifting arms islimitedfby engagement of their' tappets 36v with `the lower stops 38. 'In the eventthat the shaft V113 is rocked by .the depression ofthe `pedal/l0 when no barrelis' presenten the platform excessl inward throw and possible displacement of the gripper arms is prevented by engagement ofthe tapi pets 36 with the'upper stops 39 of the gri )per arms.

wing to theA fact'that a single depresy sion of the treadle 4() of this mechanism will produce a gripping andi centering of the bai'- 1:5

reli as: well as Va lifting `effect of thersame fromthe platform the. barrel is very easilyA and quickly placedina position'i-nr which the operator can quickly and `convenientl'yt'urn the'barrel end for end onv the' rubber pad CII Cil

V19 and then can, by releasing the pressure on the treadle 40, as quickly lower the barrel on the platform and again disengage the reversing mechanism therefrom leaving the barrel in the proper position to be operated upon the second time by the headingup, mechanism without requiring a second centering operation for this purpose.'

This barrel reversing mechanismis very rugged in construction and notl liable to get out of order under the severe usage to which the same is likely to be subjected while in use and it is very effective in its operation of raising and lowering the barrel to permit of such reversal without requiring more than ordinary manual effort for this purpose, thereby materially increasing the out-- put of the barrel making machine in connection with which the same is used.
