16 Claims.

Our invention relates to apparatus for making barrels and the like and has reference more particularly to the completing of the barrel after manent hoops to the barrel that our'present ina the staves have been assembled and temporarily securedin barrel form.

In the manufacture of barrels of the type col rnonly employed for shipping fruit and vegetables, the staves areusually set up or assembled and shaped in barrel form in a barrelraising machine with a hoop or retaining ring applied on each end for temporarily holding the assembled 1 strives-in the barrel form. After this assembling and shaping operation, the resulting structure is taken to another machine where end and inter mediate hoops are permanentlyfastened around the barrel, at which time the bottom may also be secured in place, and it isto .amachine for and the operations of applying the bottom and per vention particularly relates, althoughit is contemplated that certain features thereof may be' used inmaking barrels otherwise than according to the above indicated procedure or may be used in making articles other. than barrels;

1 our present machine a stationary anvil which is arranged to permit the assembled barrel structure to be readily applied endwise thereongis shaped. to conform to andbe engaged by successive circumferential portions of the barrel wall and has barrel rotating and hoop stapling removal of the barrel assembly to and from the hoop applying machine; to permit a stationary anvil to be employed in co-operation with fastener applying devices for securing hoops around a barrel; to automatically advancesuccessive portions of the barrel wall over the anvil to the fastener applying devices; to insure a shaping of the staves to conform to the contour of the anvil as they are advanced to thehoop applying devices; to permit a barrel end wall or bottom to be conveniently applied to the barrel as the hoops are fastened therearound; to provide an improved method and means for supplying and attaching an inside bottom hoop to the barrel; to apply and fasten this hoop and to secure the bottom in place at the same time that the outside hoops are fastened onto the barrel; and in general to improve the methods of and simplify the apparatus for making barrels and the like.

' Referring to the drawings, the reference numeral -16 indicates the base of the machine which has a standard or frame member 17 extending upwardly therefrom substantially at the middle, andsaid standard or frame 17 terminates at its upper end. in a forwardly extending arm 18 havfront side with a flat attaching face 20 to which,

a mounting bracket 21 is secured by cap screws 22 (See Fig. 4) arranged at suitable places therearound. This mounting bracket 21 has an annular forwardly extending web 23 (See Fig. 5) recessed at the top to form a gear cavity for the gear 24, and this web 23 has an inwardly extending flange 25 around the forward edge with a forwardly extending spacing rim 26 and spaced apertured lugs 27 around the inner edge of said inwardly extending flange 25.

The barrel anvil, indicated as a whole at 28, which supports the barrel assembly in the operations of stapling the hoops therearound and attaching the bottom thereto, is of a length corresponding to the length of barrels tobe made, and has a mounting plate portion 29 at the rear end secured by the bolts 30 to the mounting lugs 26 of the mounting bracket 21 so that said anvil extends forwardly under the arm 18 of the standard or frame 17, the anvil mounting plate portion 29 being separated by the spacing rim 26 and lugs 27 fromthe inwardly extending flange 25 of the mounting bracket to form an annular channel 31 for a purpose hereinafter explained.

The top face 32 of the anvil 28 is curved longitudinally and transversely to conform to the interior surface of the barrel and is formed along each side with a depending skirt or flange 33 which projects outwardly from the mounting plate portion 29'and serves to stiiien and give rigidity to the anvil, said flanges 33 being shaped longitudinally as shown in Fig. 1 and the anvil being of such width to permit the contracted end of a barrelstructure to pass readily over the raised central portion of. the anvilin applying the barrel structure. thereon and removing same therefrom.

This anvil 28 supports the barrel structure as the hoops are applied therearound and co-operates with stapling devices to fasten the hoops around the barrel, the latter being rotated or slid circumferentially over the anvil in a step by step manner to bring successive portions of. the barrel and hoops or hoop strips under the stapling devices. In the present case an end wall or bottom is secured in the end or" the barrel structure at the same time that the hoops are applied around the barrel and the mechanism that staples the outside bottom hoop onto the barrel is also arranged to staple into the edge of the barrel end wall or bot- 1 tom and to secure a narrow internal bottom supporting hoop in the extreme end of the barrel.

This end wall or bottom of the barrel is clamped in position at the outer end of the anvil so as to be located at suitable distance within the end of the barrel structure on the anvil to provide allowance for the inside bottom supporting hoop and rotates synchronously with the barrel as the latter is advanced in the step by step manner over and around the anvil.

For holding the barrel bottom and permitting rotation thereof, a shaft 34 is journaled at its inner. end in a central bearing 35 of the anvil attaching plate portion 29 and at its outer end in a bracket 36'which depends from the top wall of the anvil near the outer end, said shaft fastened on the shaft 34 at the inner side of the bearing 36 to co-operate with the clamp plate support 38 for holding the shaft against axial movement. A clamp plate 41, which may be centrally apertured as indicated in Fig. 8, is slidably engaged in the outer end of the recessed support 38, being confined by the marginal flange 39, and is carried by pins 42 which are secured at intervals around and project rearwardly from the clamp plate, through corresponding apertures in the clamp plate support 38. A s ring 43 is pro vided on each pin 42 between the clamp plate 41 and clamp plate support 38 for resiliently holding the clamp plate 41 in its outermost position which is determined by nuts 44 which are threaded on the inner ends of the stems and may be adjusted to regulate the outermost position of the plate 41. This plate 41 serves as a cushion clamping member against which the barrel bottom is engaged in the barrel stapling operation and in order to hold the barrel bottom against lateral displacement when clamped against the plate 41, and to insure rotation of the barrel bottom by and with the cushion plate 41, the latter has pointed pins or cap screws 45 threaded therethrough at intervals therearound with their pointed ends projecting outwardly from the outer face of the plate 41, each of said pins 45 being provided with a lock nut 46 for holding the pin in the adjusted position.

A swinging clamping member 47 co-operates with the cushion clamp plate 41 to hold the barrel bottom in position, said clamping member being in the illustrated structure in the form of a spider with a flat annular rim 48 with a flange 49 around the facing the anvil in the upraised position and cooperates with the cushion plate 41 to clamp the barrel bottom therebetween. This flange also serves the further purpose of supporting the hoop strip which is wound therearound to form the inside bottom hoop of the barrel and is of a width corresponding to the width of the hoop stock so as to accommodate the latter between the flat annular rim 48 and the barrel bottom when the latter is clamped between the flange 49 and the cushion plate 41.

For supporting the clamping member 47 and permitting the latter to be swung to and from the end of the anvil 23, the member 47 has depending arms 50 with aligning bearings 51 at their lower ends for the pivot pin or short shaft 52 which is locked in the bearings 51 by the set screws 53 and is pivoted in spaced bearings at the upper end of the bracket or standard 54 which is fixed on the base 16. A. counterweight 55 is secured on the shaft 52 at one end to facilitate the raising and lowering operation of the clamp member 47 and is arranged, when the clamp member is thrown downwardly to strike against a spring stop 56 which is secured to and extends upwardly from the base 16. A handle 5'? is provided on the outer side of the clamping member 47 for manipulating same and there is also a latch 58, the

arrangement and operation of which will be explained more fully hereinafter, which is pivoted on the superstructure above the anvil, and which said latch engages the top of the clamping member 47 in the upraised position to hold said member 47 in the clamping position.

As hereinbefore indicated, the barrel is advanced or slid circumferentially in a step by step manner over the anvil 28 for winding and stapling the hoops therearo'und, and the barrel bottom is rotated step by step with the barrel, this being accomplished through a ratchet ring 59 at the inner edge which is at the side 3 sand around the peripheral edge of this flange or .inner end of the anvil 28. This ratchet-ring is mounted to rotate on anti-friction bearings which are arranged at intervals around the outer side of the spacing rim 26 of the mounting said bracket and the mounting plate portion 29 of the anvil, said bearings being mounted to rotate freely in said space or channel on studs 61,

which project forwardly from the said flange 25 and said ratchet ring having an inwardly ex tending bearingrim or flange 62 fitting rreelyin the space or channel 31 and running on the antifriction bearings 68 so that the latter support the ratchet ring for rotation around an axis concentric with the axis of the barrelwhen the latter is in the staplingposition on the anvil.

This ratchet ring projects over the rear end of the anvil 28 as indicated in Fig. said anvil having the top wallrecessed or provided with a step 'or offset 68 at this place to accommodate said ratchet ring and a forwardly extending bevel edged flange64 thereon, the-outersurface of which is arranged substantially flush with the supporting surface of the anvil so that the extreme end edge of the barrel, and the retaining ring, or hoop thereon, may readilyengage around the flange 64, when the barrel is applied on the anvil. An abutmentring or flange 65 surrounds the flange 64 along the rearward edge of said flange 64 and next to the elevated ratchet toothed portion of the ra chet ring 59, to form a strip against which the end of. the barrel or the retaining ring or hoop thereon when the barrel is fully applied on the anvil, and this abutment ring serves the additional purpose of confining the ratchet pawl, which actuates the ratchet ring, against lateral displacement toward the anvil and the barrel thereon.

of the ratchet ringt the latter is formed with 7 an outwardly extending flange or web 66, which likewise serves to confine the ratchet pawl on the ratchet toothed portion of the ratchet ring web 66 is a rearwardly extending circumferential flange 6'1 with'teethon the inner side forming aninternal gear which meshes with the spur gear ,24, said latter gear being fixed on the shaft 68 which extends from end to end of the anvil, under the top of the latter, and is journaled at its rear end in afbearing 69 of the anvil attaching plate portion 29 and at its forward end in a bearing provided therefor in th e bracket 38 and at intermediate points in bearings '70 and Z1 which deprojecting upwardly, through slots 74 and '75 in the top wall of theanvil, a sufficient distance to engage the interior surface of the barrel for advancing the latter circumierentially over the top of the anvil. The feed wheel 72 which is located so as to engage the bilge or substantially midway between the ends of the barrel is slightly larger than the feed wheels 73 which latter are located respectively between the middle and ends of the barrel just beyond the locationwhere hoops are to. be applied around the barrel, and these feed wheels 73 preferably have serrated peripheral faces as shown in Figs. 1, and 7 to insure a positive gripping or. thebarrel surface with which they engage.

These feed wheels '72and 73, as shown in Fig. 2,

are located at one side of a verticallongitudinal plane through the center of theanvil 28 and at the side from which the barrel wall is fed over the anvil to a longitudinal series of staplers above and along the center of the anvil, and each feed wheel has a roller (more fully described hereinafter) above and co-operating therewith to hold the barrel wall against the respective feed wheel so as to insure a positive advancing movement of the barrel walltothe staplers For rotatingv the clamp plate support 38 and clampplate 41 and the barrel end wall or bottom which :is clamped thereagainst, simultaneously with and at, the same rate as the advancing movement of the barrel around theanvil 28, the shaft 68 which operates the feed wheels '72, 73 has a pinion 76 fixed thereon which meshes with an idler pinion 77 on the short shaft or stem '78 which is carried by the bracket '79 of the bearing 71, and this idler 77 meshes with the spur gear 80 which is fixed on the shaft 34, the ratio of the gears76, and 80 and the communication of movement through the idler 77 being such that the shaft 34 and clamping device 38, 40 thereon and the barrel end wall or bottom when engaged with said clamping device will rotate simultaneously in the same direction and at the same-rate as the barrel is advanced or rotated around the anvil 28.

The barrel structure in connection with which the illustrated machine is intended to be used is made up, as shown in Fig. 6 of. a circumferential series of staves 81 with their ends bent inwardly, this shaping of the staves in barrel form being usually effected in another machine where it is the practice to apply on one of the contracted endslof the barrel stave assembly a hoop 82, which is subsequently fastened onto the ends of the staves and becomes the outside bottom hoop of the barrel, and on the other contracted end of the barrel assembly a retaining ring or band 83, which ,is merely used to hold the barrel in shape until the permanent hoop is attached at this end, and which said retaining ring is removed after the barrel is completed, the permanent hoop being attached atthe latter end of the barrel assem biy at a'sufficient distance from the ends of the staves to permit a hoop which is usedin applying a cover or in closing the end of the barrel, to be slipped down over and secured to the projecting ends of the staves beyond the permanently attached hoop.

In our present machine which is designed to complete a barrel structure which ."has been preliminarily assembled in the above manner, although it is to be understood that this is merely illustrative and that our invention is not necew sarily limited thereto, a barrel bottom 84.- and narrow inside bottom hoop 85 are secured in that i end of the barrel stave assembly which is confined by the previously applied hoop 82 and hoop strips 86, 87 and 88 are wound around the barrel stave assemblyand secured thereto by stapling devices whichalso at the same time permanently fasten the hoop 82 onto the barrel.

These stapling devices are preferably arranged in pairs over the locations of the hoops or hoop strips 82, 88and 87 on the anvil with a single stapling device over the location of the hoop or devices in themselves are not new and any suitable type of stapler or other fastener applying device may be used although we prefer to arrange those over the locations of the hoops 82, 86 and 37 in pairs and to arrange the pair of staplers over the hoop 82 in a particular manner to locate and apply the stapler in an advantageous manner to the barrel bottom and inside bottom hoop.

Each stapling device comprises a stationaryhousing which is mounted on the beam 89 as indicated at 90 in Fig. 2, the stapler housings being indicated at 91, 92, 93 and 94 over the locations of the hoops 82, 86, 8'7 and 88 respectively. In each of the housings 92 and 93 are a pair of vertically reciprocable staple cutting, forming and driving mechanisms as'indicated somewhat diagrammatically at 9595 in Fig. 2 which are arranged at opposite sides respectively of the longitudinal center line of the anvil and substantially in circumferential alignment so as to drive staples in pairs as indicated at 96 in Fig. 6, each of said staples 96, however, being preferably arranged at an angle as shown so that the legs or prongs of the staple engage at laterally separated places across the width of the hoop stock. A single stapling mechanism indicated somewhat diagrammatically at 97 is provided in the housing 94 and is located substantially at the longitudinal center line of the anvil for applying the staples 98 which secure the hoop 88 to the barrel, said staples also being preferably arranged at an angle in like manner to the staples 96.

The stapler housing 91 which as above indicated is provided with a pair of stapling mechanisms for securing the bottom outside hoop 82,

inside bottom hoop 85 and bottom 84 to the bar rel stave assembly differs from the staplers 92 and 93 in the respect that the stapling mechanisms indicated diagrammatically at 99 and 100 in Fig. 2 while spaced circumferentially at opposite sides of the longitudinal center line of the anvil, are staggered longitudinally of the anvil so that the stapling mechanism 99 is located over the place where the inside bottom hoop '85 is to be applied to the barrel while the stapling mechanism 100 is located over the peripheral edge of the barrel bottom when the latter is clampedbetween the flange 49 of the clamping member 47 and the cushioned clamping plate 11, and moreover while the stapler mechanism 99 is arranged to drive the staples 101 in substantially the same diagonal relation to the hoop 82 as the staples 9G and 98 or" the hoops 86, 87 and 88, the stapling mechanism 100 is arranged to drive the staple 102 at only slight angle to the length of the hoop 82, this arrangement being provided to insure penetration of the staple ends or prongs into the body of the barrel bottom 84.

For operating the stapling mechanisms, a rack bar 103 is located adjacent each housing 91, 92, 93 and 94 and each rack bar is mounted for verticai reciprocatory movement in upper and lower guides 19% and 105, the forms of which are secured to the side of the forwardly extending arm 18 of the machine frame by bolts 106 the heads of which engage in the undercut slot 107 of the frame arm 18 to permit adjustment lengthwise of the anvil and the latter of which are formed as a part of the respective housing 91, 92, 93 or 9 1 and are adjustable therewith longitudinally of the anvil. Each rack bar 103 has a bracket 108 secured thereon which extends over the respective housing 91, 92, 93 or 94 and is connected with the stapling mechanism or mechanisms thereof, it being understood that the brackets 108 of the stapling device 91 and 94 are of somewhat different form than the brackets of the mechanisms 92 and 93 inasmuch as there is only a single stapling mechanism in the housing 94 and the pair of stapling mechanisms in the housing 91 are arranged differently than the stapling mechanisms of the housings 92 and 93.

Each rack bar 103 is provided at the corresponding side with a toothed section and said rack bars and the stapling mechanisms connected therewith are operated in unison from an oscillating shaft 110 which is journaled in bearings on the standard or frame 1? and the depending hanger 19 and provided with four segmental gears 111 fixed thereon and meshing with the toothed section 109 of the respective rack bar 103 so that oscillatory movement of the shaft 110 imparts a corresponding vertical reciprocatory movement to all the rack bars 103.

A separate feeding device is provided for each stapler mechanism 91, 92, 93 and 94 for supplying the wire from which the staples are formed, each or" which feeding devices comprises a bracket 112 which is slidable along the two shafts 113 and 114 and is locked in adjusted positions by the set screw 115 which clamps the bracket to the shaft 113. The shaft 113 serves merely as a guide and support for the brackets 112 and has the ends secured respectively to the machine standard 17 and the depending hanger 19 while the shaft 114 is journaled at its ends to rotate in bearings on said standard and hanger and operates the wire feed rolls of the feeding devices.

The feeding device for each stapler mechanism 91, 92 and 9S, two sets of feed rolls arranged respectively on opposite sides of the respective bracket 112 so as to feed separate wires to the pair of staplers with which each of the stapler mechanisms 91, 92 and 93 is provided, while the bracket 112 of the feeding device for the stapler mechanism 94 has only one set of feed rolls as only one wire is required therefor. Each set of wire feed rolls is substantially alike and comprises a narrow feed roll 116 which is fixed on the shaft 114 by a set screw 117 so that it may be adjusted along the shaft 114 with the bracket 112, and this feed roll has an integral gear 118 along one side meshing with a gear 119 on the side of a small feed roll 120, which said roll 120 together with its integral gear 119 is carried on a swinging bracket or arm 121 which is pivoted at 122, on the bracket 112, a spring wire 123, (a fragmentary portion of which is shown in Fig. 2) being provided with the outer end held in any convenient manner (not shown) so as to impose a tension on the bracket to hold the roll 120 against the upper roll 116 and the gear 119 in mesh with the gear 118. A tube Behaving the outer end secured to bracket 112 at the point of delivcry of the wire from the respective feed rolls leads from said rolls to the respective staples to guide the wire thereto as it is advanced between and by the operation of the rolls 116 and 120.

As hereinbeiore indicated a roller is provided above each of the barrel feed rolls 73, 74 to hold the barrel wall against said feed rolls and insure positive advance movement of the barrel wall to the staplers, said rollers being arranged so that they can be raised from the operative position to afford clearance for applying the barrel to and removing it from the anvil, the said rollers being indicated at 125. Each roller 125 is mounted on the lower end of a separate rack bar 126, said rack bars being mounted to slide vertically in a guide 127 on a bar 128 which extends across thefront of the staplers and is secured by lateralextensions or brackets to the stapler supporting beam 89. A gear segment 129 is pivoted tothe bar 128 adjacent each rack bar 126 and in mesh with the teeth-of the respective rack bar and each gear segment hasan arm 130 extending upwardly therefrom and terminating in a bifurcated end which straddles a rod 131 which is mounted at one end in a bracket 132 on the machine standard 17 and ad jacent the other end in a bracket 133 on the adjoining guide 127, so asto slide longitudinally in said brackets. A collar 134 is secured by a set screw on the rod 131 at the side of therespective arm 130 remotefrom the machine standard to serve as a stop against which the bifurcated end of the respective arm 130 is resiliently held by a spring 135 which is compressed between a sliding washer or collar 136 on the rod 131 and a collar 137 which is locked by a set screw to the rod 131, it being understood that there is a separate spring135 for each segment arm 130.

For operating the rod 131 and segments 129 to raise and lower therollers125, a hand lever 138 is pivoted to the depending hanger portion 19 of the machine frame and has the outer end of a link 139 pivoted thereto at 140, the other end of said link 139 being pivotally connected to the end of the rod 131 as at 141 so thatwhen the hand lever 138 is in the upraised position shown in Fig. 1,the rod 131 is at the extreme position of its movement/to the right, as viewed in Fig. 1, in which position the collars 134 are engaged against theupper ends of the respective segment arms 130 and the segments 129 held thereby in the position wherein the rollers 125 the barrelwall and are elevated sufficiently above the anvil 28 to permit the barrel to be readily applied on or removed from the anvil, When, however, the hand lever 138 is turned down to the outwardly eX- tending position shown by dotted lines in Fig." 1, the rod 131 is slid forwardly or to the left as viewed in Fig. 1, the first movement thereof, by rcasonof the upper ends of the segment arms being confined between the collars 134 and springs 135, resulting in an operation of the gear wheels 73 and 74.

This hand lever138, in addition to serving the purpose of controlling the pressure rollers 125, is employed to lock the clamping member 47 in the upraised positional; the end of the anvil 28, a latch member 142 being pivoted at .143 onthe lower rack guide 105 which is nearest to depending arm 19 of the machine frame in position to swing down and engage the clamping member 47 at its upper end and said latch member beingope'rated bythehand lever 133. This latter operation is accomplished through a link 1444 which has one end pivoted at 145to the latch member and the other end pivoted at 146 toa crank portion .147 of the handlever 138, a stop 148 being provided for the hand lever 138 rollers 125. secured to the lower end of the rack bar 126 the latter against the feed to limit its downward movement, and it will be observed that when the said hand lever is in this downturned position against said stop 148,

the pivot 140 has just passed centerso said lever 138 is held in the position against the stop 1.48 by the tension of the springs 135, and further that the pivot 146 has also just passed center so that the latch member 142 is locked in place to hold the swinging clamping member 47 in the clamping position at the end of the anvil and cannot be released except by raising the hand lever from the position in which it is held by the springs 135 against the stop 148.

The outside bottom hoop 32 of the barrel is, as hercinbeiore indicated; usually applied on the end of the barrel stave assembly in the raising machine and transferred from the latter with the ba rel stave assembly to this present machine i eh staples said hoop onto the ends of the staves 81. The hoops 86, 87 and 88, however, are supplied at the present machine in the form of strips which are fed under the respective staplers 92, 93 and94 by the hoop guides 149, 150 and 151 and wound around the barrel, said hoop guides being mounted to be raised and lowered by the raising and lowering operation of the To this end the hoopguide 149 is which is located adjacent the stapler 92, while the hoop guide 150 is secured to the lower end of the rack bar 126 which islocated adjacent the stapler 93 and the hoop guide 151 is also secured V to the latter rack bar througha bracket 152.

An internal hoop of narrow width is also provided atthe lower end of the barrel to assist in securing the barrel bottom 84 in place and this hoop is supplied in the form of a hoop strip which is wound and stapled in place as the other hoops are applied.

When the barrel staveassembly is in position on the anvil and the clamping member 47 posi tioned' at the end of i the anvil, the flange 49 of said clamping member 47 engages against the outer side of the barrel bot em 84 and clamps the latter against the yielding clamping plate 41 while the annular ring 48 of the clamping member47' engages against the ends of the barrel staves 81 so that there is only a restricted space between the end portions of the barrel staves and the flange 49 and between the barrel bottom 84 and the annular rim 48 to accommodate the hoop strip which forms the inside bottom hoop 85. i

For supplying the hoop strip to this restricted space, the annular rirn48 is formed with an elong gated slot 153 in line with or opening into the rethe clamping flange 49 and ends of the barrel staves Sl, it is fastened in place by the stapler 99 which. applies at successive circumferentally spaced points, the staples 101 which also serve to fasten the bottom hoop 82 to the barrel.

To facilitate thefeeding of the hoop stock 154 into the restricted space within the end of the barrel, the clampingflange 49 is cut away adjacent the inner end of the slot-153' as shown in Fig. 9 and a staple clinching disk which is rotatably mounted to turn freely on'a pivot 156 carried by the clamping member 47, has the top peripheral portion located in this cut away place of the flange 49 substantially as shown in 9 so that the hoop strip 154 as it emerges at the inner end of the slot 153, is supported by an: moves over the top edge of the clinching disk 155. This disk 155 which is of a suitable thickness and so mounted that the face next to the barrel bottom is held by the clamping flange 49 just out of pressure contact with the outer surface of the barrel bottom 84, is mounted in vertical alignment with the stapler mechanism 99 so that the staple is driven by the latter directly over the pivotal axis of the disk 155 and the latter has the peripheral edge grooved as indicated at 157 in Fig. 10 to turn inwardly and clinch the ends of the staples 101 as they are applied to the barrel.

The power to operate this machine may be applied as in the illustrated structure, by belt to a pulley 158, fixed on a shaft 159 which is journaled near one end in a bearing of the bracket 160 which is secured to the machine base 16 and at the other end in a bearing 161 of the machine standard 17, and this shaft has a pinion 162 fixed thereon which meshes with a gear 163 which is mounted to rotate freely on a shaft 164 which is journaledat one end in the bracket 160 and near the other end in a bearing 165 on the machine standard 17 beyond which the latter end of said shaft 164 projects, a gear cover 166 being mounted on the bracket 160 to enclose the upper portions of the pinion 162 and gear 163.

The shaft 164 from which the various mechanisms of the machine are operated has an operator controlled clutch connection with the constantly driven gear 163, the latter having a plurality of clutch lugs at intervals around the hub, which may be provided by securing pins, one of which is indicated by dotted lines at 167 in Fig. 11, into corresponding bored-out openings or sockets in the hub portion of the gear 163. A clutch drum 168 is fixed on the shaft 164 just beyond the projecting ends of the clutch lugs 167 and has a bored-out opening 169 in which the clutch pin 170 is mounted to slide to and from engagement with the clutch lugs 167 of the gear 163. This clutch pin is cylindrical in form with a flattened side face at the engaging end to engage against correspondingly flattened faces 172 with which the clutch lugs 167 are provided, and in order to hold the clutch pin 170 against turning movement in the opening 169 and to hold 2' the clutching flat face 171 thereof in position to engage flatwise against the clutch faces 172 of the clutch lugs 167 the rear end of said pin 170 is bifurcated or slotted and straddles the uin 173 which is secured to the clutch drum and extends across the opening 169. The clutch pin 170 is also bored out longitudinally to receive a spring 174, the rear end of which engages the pin 173 which is secured to the clutch drum and wardly to the clutching position when the latter is free to move.

Midway between the ends of the clutch drum, the latter is provided with a peripheral groove 176 to which the side of the clutch pin 170 is exposed and the latter is notched as indicated at 177 to provide a beveled can portion 178 which may be engaged by a clutch trip latch 179 in the groove 176 for retracting the clutch pin 170 and holding it in the retracted position. This clutch trip latch 179 is pivoted at 180 to an upwardly extending arm 181 of a bracket 182, which is secured to the machine base and provided with a bearing 183 for the shaft 164, and said latch 179 has an arcuate edge face 184 which seats down in the clutch drum groove 176 and at the end has a beveled face 185 facing so as to engage the cam portion 178 of the clutch pin 170 and wedge the latter out of clutching engagement.

For controlling the clutch trip latch 179, the latter is connected at its free end by a link 186 with the end of one arm of a bell crank 187 which is pivoted at 188 on the bracket 182, and the other arm of the bell crank is connected by the rod 189 to an upstanding arm 190 of a foot lever 191 which is pivoted at 192 to the base 16 so that the tread plate 193 is located in a position conveniently accessible to the operator, a spring 194 being connected with the upstanding arm of the treadlever to normally hold the tread lever in the upraised position wherein the tension of the spring 194 acting through the rod 189, bell crank 187 and link 186 tends to pull the end of the clutch trip latch 179 down into the clutch drum groove 176 to the clutch releasing position.

For operating the stapling devices 91, 92, 93 and 94 from the shaft 164, the shaft 110 to which all the staplers are geared as hereinbefore described, is provided with a crank disk 195 on the rear end having a crank pin 196 which is connected by the connecting rod 197 with an eccentric strap 198 which engages around the eccentric 199 on the shaft 164 so that in every rotation of the shaft 164, the crank disk 195 and shaft 116 are oscillated and cause a simultaneous stapling operation of all the staplers 91, 92, 93, 94.

Another eccentric 200 is also provided on the shaft 164 just in front of the bearing 165 and has an eccentric strap 201 therearound which is connected by the connecting rod 202 with the outer end of a lever 203 which is pivoted at its inner end on the axis of the stapler wire feed Wheel shaft 114 and this lever 263 has a pawl 264 pivoted thereon held by a spring 205 in engagement with a ratchet wheel 206, fixed on the shaft 114 so that at a certain time in each rotation of the shaft 164 and in proper timed relation with the operation of the staplers 91, 92, 93 and 94, the shaft 114 and all the feed wheels 116 thereon are advanced sufficiently to feed the proper amount of wire to the staplers.

The barrel feeding mechanisms are also operated from the shaft 164, the latter being provided at its forward end with a cam 267 which is engaged by a roller 208 on the lower end of the lever 209 which is pivoted midway between its ends as at 216 to the machine standard 17, said roller 208 being held in engagement with the peripheral face of the cam 207 by the spring 211. At the upper end of the lever 209, a long ratchet pawl 212 is pivoted thereto and extends over and engages by gravity with the ratchet tooth portion of the ratchet ring 59 so that in each revolution of the shaft 164 the barrel on the anvil 28 is advanced in suitable timed relation with the staplers, a distance represented by one tooth of the ratchet ring 59.

In using this machine, assuming that power is being applied to the pulley 158 and the gear 163 is being constantly driven, and the clamping member 47 is in the downturned position and the handle 138 in the upraised position, a barrel stave assembly with the retaining ring 83 on one end and the hoop 82 on the other end is applied on the anvil 28 with the end of the barrel assembly which is to become the top of the barrel and which has the retaining ring 83 thereon next to the ratchet ring 59 and the end of the barrel clamping member 47 is turned upwardly and locked in the upraised position by depressing the lever 138 until it strikes the stop 148. This clamps the flange 49 of the clamping member 4'? against the barrel bottom 84 so that the latter is held in a fixed location between the flange 49 and the cushion clamping plate ,41 and also en gages the annular rim 4.8 of the clamping member 47 against the hoop 82 and the ends of the staves so that the barrel is trued up and the hoop 82 properly located on the end. i

The depressing of the lever 138 for locking th clamp member 47 in the upraised position also shifts the rod 131 forwardly thereby depressing the rollers 125 and applying a holding tension thereon so the barrel wall is held against the feed rollers '72 and '73. Hoop strips are then' inserted in the hoop guides 149, 150 and 151 and the narrow hoop strip in the slot 153 of the clamping member 47, whereupon the operator presses downwardly on the pedal'193 thereby lifting the clutch latch 179 and releasing the clutch pin 170 which thereupon engages one of the clutch lugs 1670f the constantly rotating'gear 163 and causes the shaft 164 to rotate therewith, and this rotation of the shaft 164 operates the staplers, wire feeding devices and the barrel feeding mechanism, the latterbeing arranged through the ratchet connection 212 and the ratchet ring 59 tohave a step by stcp'moveinent so that the advance movement of the barrel over the anvil 28, and corresponding movement of the barrel bot tom Mtherewith takes place between operations of the stapling devices and the operationof the stapling device takes place between advancing movements of'the-ba'rrel;

The machine will continue operating as long as the-pedal 193 is depressed and ordinarily is continued until the stapling of the hoops around the barrel is completed, although it may be'interrupted at any point, it being observed that with the described clutch mechanismthe interruption always takes place at the same point in the revolutionof the shaft 164 which is so arranged that at the time of interruption the staplers are elevated and the barrel feeding mechanism has just completed a step of itsmoveinent. Thus when thepedal 193 is next depressed the first operation of the hoop strips to the barrel before the beginning of the advance movement of the latters In order to prevent overthrow ofthe mechanisms and to insure prompt stopping of the: shaft 16% as soon as the clutch pin 170: is retracted by the clutch trip 1'79 from clutching" engagement with the gear 163, a brake band 213 hrakeband. i

After the stapling of the hoops around the barrel has been completed, and the pedal 1.93 releasedto disconnect theclutch, the hand lever 138 is thrown upwardly to releasethe clamping member 47 and raise the rollers 125, whereupon the clamping member 4'7 is turned downwardly away from the endof the anvil after which the I barrel may be readily withdrawn from the end of the an vi128. After its removal the retaining ring 83 which has been used to temporarily hold the staves at one end of thebarrelinay be removed. i i V For facilitating the removal of the barrel from the anvil 23, and to assist in positioning the barrel thereon if desired, a lever 216 may be provided whichis pivoted at 217 to the bracket and has one arm thereon extending upwardly and provided at itsend with a saddle 218 noeltioned directly under the location of the barrel on the anvil 28 and adapted to be'raised into en gagement with and lift the barrel while on the anvil. The lever 216 has the other arm therein extending downwardly and provided with a pedal 219 in convenient location for access by the operator and a spring 220 normally holds the lever against a stop 221 in whichposition the saddle 218 is below the position of the barrel on the anvil and does not interfere with the applying of the barrel or the removal thereof from the anvil. 1
