MACHINE FOR CRIMPING DRY-CF|LL JACKETS.

Application filed .Tune 1, 1921.

To all whom it may concern:

Be it known that I, HERBERT L. Bonorrnns, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in. Machines for Crimping Dry-Cell Jackets, of which the following is a specification.

This invention relates to crimping machines and particularly to an improved machine for crimping jackets for dry cells, but it will be understood that various novel features thereof may be employed in other types of machines for operating on tubular articles.

Cells of dry batteries have heretofore gen erally been enclosed in jackets made of tubular paper or cardboard bodies having separate cupped paper caps glued to and closing the bottom ends thereof. Such jackets are not entirely satisfactory because these caps often loosen and drop off, and the construction is also comparatively expensive and unattractive.

A dry cell jacket having an inwardly crimped bottom end is a more reliable, inexpensive and attractive construction, and one of the objects of this invention is to provide a comparatively simple machine in which. such jackets may be economically crimped.

Another object of this invention is to provide a novel combined chuck and crimping mechanism especially adapted for crimping the ends of such jackets and similar tubular bodies.

The above and other objects and the novel features of this invention will be apparent from the following description taken in connection with the drawings, in which Figs. 1 and 2 are, respectively, a side elevation and a top plan view of a crimping machine embodying this invention,

Generally speaking, a jacket crimping machine embodying the present invention comprises a suitable carrier, such as the intermittently rotatable turret T, which has a series of tube gripping devices, such as the The turret moves the chucks in succession past means for applying oil to the ends of the tubular bodies, to a station where these bodies are automatically operated upon, and then to a station where the tubular bodies are automatically ejected from the chucks, as by the stripping means E. In the present machine the means for operating on the tubular bodies comprises a spinning or crimping mechanism, having a fixed crimping member S that is rotatable and movable relatively to the body to be operated upon. and cooperates with successive crimping members S on the chucks to crimp or roll the end of such body inwardly upon itself. The turret is desirably locked during the crimping operation. The turret, the crimping means and the as sociated mechanism are operated from suitable power means, such as an electric motor M located in the base B of the machine frame F.

Referring to the drawings, Fig. 4 particularly, the turret T comprises a horizontally disposed table secured to. a hub 20 that is rotatable on the support 21 mounted on a pedestal 22 supported on a ledge 42 on the base B. The hub carries a spur gear 20 that meshes with the spur gear 223 on a shaft 23 which may be intermittently rctated, as by a geneva gear G (see l r's. and 12) consisting of the gear member 24L having the usual radial slots 2a'-1 engageable by a pin or roller 251 on a gear member 25 keyed to the main drive shaft T), whereby one revolution of the latter turns the-turret 90 degrees. The shaft D continuously rotated during the operation of the machine by the worm gearing Ti comprising a worm driven by a pulley P, tl "1 is belted to the motor M by the belt Suitable anti-friction bearings may be provided for the rotatingparts as shown.

A plurality of chucks G are mounted on theturret T, and as shown these chucksmay be arranged in pairs. Each chuck is adapted to internally engage and support a tubular body,such as a tubular paper acket J and,'while the machine is especially suitable for crimping the ends of straight-lapped paper jackets which have an extra thickness of paper at the lap, it will be understood that novel features of the machine may beembodied'in machines for operating uponor crimping other tubular articles.

By the duplex arrangement illustrated, the

production of a given machine is consider ably increased without a proportional increase in the cost of the machine or power, which materially reduces the crimping expense per jacket.

Inasmuch as the chucks are alike in construction, only one of them will be described in detail. Referring to Figs. 7 and 9, each chuck comprises a base 26 having a stem 261 that depends through an opening in the turret T, and having an axial opening to. provide a sliding bearing for the chuck spindle N. The chuck .comprises a number of longitudinally extending gripping sections 27 which may have curved ere ter ior "faces which lit into and form a substantially cylindrical supporting surface "for the tubular acket J. The segmental sections 27 have registering transverse grooves 271 near their ends to receive circumterem tial elastic bands R which are so tensioned as to hold the sections together and tend to contract them inwardly toward the axis of ,the chuck. The chuck sections 27 are supported at their lower ends on the base 26 andhave radially inwardly extending ribs 272 provided with projecting portions 273 adaptedtoengage under a collar 262 on the base to hold the sections in place on the base.

Portions of the ribs 272 lit in slots 281 of a Wedge block 28 that is splined on the spindle N to permit the latter to move longitudinallyinjdependently of thex wedge block and chuck. The'bottoms of the slots 281 are inclined as at'282 and cooperate with inclined portions 27d of the ribs 272, and a spring 99 presses the wedge block against the chuck sections to yicldingly push them outwardly against the tension of the bands B so that the chuck will automatically adjust itself to lirmly grip tubes varying slightly in diameter.

Each chuck also has combined therewith a lower spinning or crimping member S with which the fixed upper spinning or crimping member S is adapted to cooperate as each chuck is moved to the crimping station. The lower crimping member S is disposed above and movable axially of the chuck and comprises a hardened plate 30 provided. with a groove 301 that cooperates with a groove in the upper crimping member S. The grooved plate 80 is clamped between two

rings

31 and 32 which may be connected together by screw threads, the inner ring 31 being rotatably supported on the chuck spindle N, as by the anti-friction bearings 3'11 and held in place on said spindle by a nut 33. The ring 31 also has radial teeth 312 on its upper face adapted to interlock with similar teeth on the upper crimping member S to clutch the two crnnping members together so that they will rotate in unison when the upper crimping member S is rotated. The nut 33 also clamps a. spring abutment 34; to the spindle fl, the ring 32 having an inwardly extending flange 3121 that engages beneath the outer edge oi: the abutment 34: whereby the up ward movement of the lower spinning head S is l nited without interfering with its rotation. C ne end of a helical spring 35 lwars against the abutment- 3 1: and the other end thereof abuts against a stationary spring support 36 that rests on the upper ends oi the inwardly projecting ribs 27:1 of the chuck sections. During the operatirm of the ma chine. the spindle N is depressed against the tension of the spring 35 as the crimping operation proceeds, carrying the abutment El and the crimping head S dmvnwardly with it as the crimping heads S and S rotate together and. crimp the upper end of the tube into the cooperating grooves of the members S and S. The com 'n-cssed spring 35 then serves as a means for restoring the crimping member S to its initial position w ion the crimping operation is completed and the spindle N is freed to ascend.

The upper crimping men'iber S which cooperates with the crimping member S comprises a hardened crimping ring 38 which has a depending rim 3S1 flared as at 38:2 to siu'round the end of the tube to be erimped. The ring 38 also has a groove 383 that eooperates with the groove 301 in the crimping ring 30 to bend the end of the tube inwardly upon itself andv parallel to the axis of the tube as the cooperating rotating crimping heads descend. The inner edge of the ring 38 is held between two clamping rings 39 and 40, connected by screw threads as shown in Fig. 7 The clamping ring 40 has radial teeth 401 adapted to engage the teeth 312 on the ring 31 to couple the crimping members S and S together. The clamping ring 39 may be secured by screw threads on the lower end of a spindle L which is journaled in an anti-friction bearing 411, the outer race of which is supported by a ring 41 secured by threads to the lower end of a sleeve 42 slidable in a boss 421 and carried by a lowering and lifting head H.

Inasmuch as the chucks and the associated crimping mechanisms are arranged in pairs, the lifting and lowering device H is ar ranged so as to lift and lower the two upper crimping heads S simultaneously, and as shown in Figs. 4, 6 and 7 particularly, carries a cam roller 43 that is supported on a shaft 431 journaled' in suitable anti-friction bearings 432 on thehead H. The cam roller 43 runs in a cam groove 441 in the cam 44 that is secured on the main drive shaft D to rotate therewith, the cam groove 441 beingdesigned so as to lower and lift the head H the desired amount at the proper time for crimping the end of the jacket. The fixed pair of crimping members S at the crimping station are arranged to be simultaneously rotated by suitable mechanism while the head H reciprocates them. As illustrated, the pair of spindles L project upwardly, through parallel sleeves 42 to which the head H is clamped, as best shown in Fig. 6, and the upper ends thereof are splined to spur gears 48, both of which mesh with a single spur gear 49 that is driven by beveled gears 50 and 51 and suitable shafting from a pulley 52 connected by the belt M to the electric motor M. The cover member 53 may be provided with suitable bearings for parts of this driving mechanism and also carries caps 531 into which the upper ends of the spindles L are movable when the crimping members S are lifted by the head H. Accordingly, the pair of crimping members S are simultaneously rotated at the same rate from a common gear while they are lowered and lifted by a common cam-operated head H.

The nairs of lower crimping members S descend with the upper pair of fixed crimping members S as the crimping operation proceeds. In order to relieve strain on the crimping mechanism, it is desirable that the pairs of lower crimping members S be positively depressed. This may be accomplished by a cam 55 mounted on and rotatable with the main drive shaft D. A lower cam face 551 of this camengages a cam roller 56 carried by a cross bar 57 that is secured by screws 571 to the lower ends of a pair of .chuck spindles N. As the cam 55 rotates,

the spindles N of the chucks in the crimping position are simultaneously depressed to the same extent as the cam 44 depresses the head H so that the cooperating pairs of crimping members S, S move together axially of the tubes as the crimping operations proceed. As the crimping operation is completed, the lower cam face 551 of cam 55 further depresses the spindles N until the shoulders 285 of spindles come in contact with and depress wedge blocks 28 against the action of springs 29, thereby permitting the rubber bands It to contract, causing the chuck aws 27 to collapse. This action releases the crimped jackets, permitting them to be removed bv the strippers E.

It is now desirable that the spindles N and thelower crimping members S at the upper ends thereof be held in depressed position until the crimped jackets are removed from the chucks. Otherwise it would be diflicult to remove the ackets, and the lower crimping members S might pull out the inwardly bent end of the tubular paper body and destroy the results of the crimping operation. For this purpose, a suitable latch K may be pivoted as at 60 on abracket 601 depending from the lower side of the turret, the latch being provided with a notch 61 at the lower edge thereof adapted to hook over the upper edge of the plate 57 when the lat ter and thc spindles N and the crimping lllElDlJGlS S have been depressed the full extent. The latch K is so weighted that the notch 61. will interlock with the plate 57 at the desired time, after which the crimping members S are held in depressed posi tion with the chucks collapsed until after the crimpedv jackets have been removed from the chucks and new tubes substituted.

During the crimping operation the turret esirably locked against rotation to preventcreeping thereof due to the friction between the elements of the geneva gear mechanism G. As illustrated in 7 and 8, the periphery of the turret is provided at intervals with sockets 64 adapted to receive the locking head 651 at the end of a locking bolt 65 movable in a guide 653 and normally pressed outwardly by a spring 652. The locking bolt 65 is released and retracted at the proper times by a lever 66 pivoted at 661 and provided with forked end 662 that straddles a pin 654 on the locking bolt 65. The lever 66 carries a cam roller 67 that runs in a cam groove 559. in the upper side of the cam 55, which effects the desired operation ofthe lever 66 each time that a pair of chucks moves into and out of crimping position.

After two jackets have been crimped atthe crimping station, the turret advances the pair of chucks with the jackets thereon to the position where they are to be removed from the chucks. The ejecting or stripping mechanism E is adapted to simultaneously strip a pair of jackets from a pair of chucks, a stripping cylinder 68 being associated with each chuck. Each stripping cylinder has an outwardly flaring mouth or lip 681 adapted to facilitate the insertion of the tubular body, and an internal ledge 682 upon which the tube is supported during crimping operation. The cylinder 68 extends a short distance up around a portion of the sectional chuck to sustain the lower end of the jacket. The cylinder 68 surrounds and has a sliding lit with the base 26 and rests upon the upper side of the turret T. The. cylinders 68 may be lifted by an angular lifting member 7 O, the lower side 701 of which is adapted to rest on the upper suriace of the turret T and is provided with openings 702 to receive the lower ends of the cylinders 68, the latter being provided with flanges 683, forming shoulders projecting over the edges of the openings 702 whereby the cylinders 68Wlll be lifted when the lifting device 70 rises. The other side 703 of the lifting member 70 is secured to a slider 71 that has suitable openings to receive vertical guide rods 72 mounted on the turret T. The slider 71 also carries a cam roller 711 on its inner side which is adapted to engage a stationary cam 73 which lifts the slider 71 and its associated ejecting cylinders along the guide rods 72 when the turret rotates from the crimping position to the stripping position, as indicated in Figs. 1 and 3.

Accordingly, when the cylinders 68 are lifted, they will carry upward the crimped jackets which rest on the ledges 682 thereof, stripping them from the chucks. By the horizontal portion 731 of the cam 73, the cylinders are held in the raised position during the entire time that the pair of chucks is opposite the stripping position. A bar may also be arranged to pass through the slots 684 in the strippers so as to engage beneath the jackets when they are raised and support them temporarily in this position when the strippers descend by droppingoff the end of cam 73, allowing the jackets to fall off into a suitable receptacle. After leaving the stripping position, and while moving another quarter turn the stripping mechanism is restored to its initial position ready for the insertion of two more tubes onto the pair of chucks. After insertion of two more tubes thepair of chucks are moved another quarter turn, upon leaving this position the latch device is released and the lower crimpmg members S are ralsed to their initial positions by the springs The latch device may be released by suitable means, as

,b cam se ment 622 secured to a uard y c a member 76 and arranged to engage the roller .62at the outer end of the latch K to swing it upwardly about the pivot 60 and trip the notch 61 away from the plate 57. Before the roller 62 reaches the segment ($22, the roller 56 engages a cam segment. 5M carried by the guard 7 6 to depress the plate 57 so that the notched member 61 maybe read ily drawn away from the plate 57. The

springs

35 and 29 which are under compression, will then act and immediately raise the spindles N and as'asociated. crimping men'ibers to their normal position. at the same time expanding the chucks to cause them to hold the tubes tightly.

The cam 73 is mounted (in a stationary cam cylinder 74: that is secured to the pedestal member 21 and a cover 75 is secured to the upper side of the cam cylinder 74 to enclose the parts and exclude dust there from and guard member 76 encloses the mechanism below the turret. A spring supported roller 77 may be provided to automatically take up the slack in the belt M. The frame F may be provided with a removable rear cover F to enable the meehanism to be readily inspected and repaired.

The upper ends of the tubular blanks may have coating of suitable substance such as para'tlin oil applied thereto to facilitate the crin'ipiug operation and to assist in retaining the crimp. As illustrated in .4, 3 and 14'. the paratiin applying means may consist of a set of three rollers 83, R4- and 85, the former running in a paratlin oi] eontainer 86 and wiping against a felt surface on the roller 84 which in turn wipes against the felt surface of roller 85, the latter engaging and coating the upper ends of the tubular bodies as they pass on their way to the crimping mechanism. The rollers maybe suitably mounted in an arm 98 that is pivoted at 89 on a bracket 90 secured to the machine frame. A pin or roller 91 on another arm 92 secured to the arm 88, engages a lug 93 to support the frame and the rollers thereon.

A finished jacket l embm'leiinu the present. invention is illustrated in Figs. 15. .6 and 17 wherein W illustrates the inwardly erimped end of the tube. illustrated. he tube that is crimpcd may be initially formed from a flat paper or cardlumrd hlanl: one side of which may carry -or-.'.ting. pr nting'or advertising matter. The blank may be more readily printed in the Hat and then may be formed into a cylinder and the edges thereof lapped and cemented or glued together, providing a double-wall seam J that is parallel to the axis of the cylinder. The inwardly erimped parat'tined end .T forms a stiffened shoulder upon which the dry cell X may be supported, the internal diameter of the jacket .T being such that it snugly fits a dry cell about six inches high and two and onehalf inches in diameter, in the specific embodiment illustrated. A circular disc Y of pasteboard or other suitable material is, however, desirably inserted in the acket J and rests loosely upon the shoulder tormed by the inwardly especially in damp places and the appearance is much improved.

While the improved crimping machine and product are shown and described in detail, it is to be understood that various changes may be made therein without departing from the spirit of the invention or sacrificing any of the advantages thereof.
