vBe it known that I, JOHN A. STEWARD, a

citizen of the'United States, residing at Rut@` land, in the county of Rutland, State of Vermont, have invented certain new and useful Improvements 1n Can-Searning Maclnnes, of

which the following is a speciiieation, reference being had therein to the accompanying drawings.

-This invention relates to a can-.seeming machine, and is particularly adapted for use in the production of double-seemed cans of angular, curved, or irregular shapes.

The invention hasfor an object to provide an improved construction of the seeminghead from which the seeming-rollers are con# trolledby means of a cam carried therein and actuating-fingers for throwing said rollorsinto an operative position.

A further object of the invention .is lto, provide an improved construction of the driving means forthe seeming-head and actuating` fingers therefor, whereby-the headmay'be rotated and the :fingers automatically thrown into o erativeposition relative to the rota- Another' object of the invention is to provi'defan improved construction ofsupportin e tableorthe Work by'which the lattenis raised into operative relation with the seaming-rollers and the driving-gear for said rollers thrown intol driving' position.- e

' Other and further objects and advantages of the invention will be hereinafter set-forth and the novel features thereof defined by the appen ed claims. i

The letter A. designates a standard having the base A and provided et the upper por tion with a supportingfarm if-iig. Belowthis arm a second supportingamr fi@ is disposed and provided. with suitable bearingdiox adapted to support the see Jing-heini andthe shoe-for the 'fingers et the lower portion `oithe standard arms A4' andrai er provided for. the support of the shaftl of ean-'ta'bie. At' the opposite side of the machine e "'olre por-` tion A is formed and proficred .any de sired number and arrangement of bearings for supporting the driving mechanism for .the entire machine. Theee parte may be altered at will in aecordanee with the .fengernents of the machine. Y A. supporting-shaft mounted the arms A. and All .ind carries at its w, end a seeming-earn This heid against rotation l means of upper portion jeoting lug A? i'roin the oi a .cross-pin B2 end with spring members clamped intoholding eontee upper' end of the shaft B, while the pivot L is die4 posed in the ears B4, which embrace the lug is provided with 'e `seentral aperture C.'

'througlrwhichthe sliet E.; tends, while surrounding this aperture .ie the. amor trackv Way Q2, within which the scanning-cam rollers travel. vThe form of seeming-cam shown in Fig. is adapted for operation upon a sub--` stantially oval can, while-the modified forni (shown at C3 in Fig. 6) is provided with a circular path, C1* for operation upon a can of simi- `lar configuration.

Surrounding the fixed shaft B is a tubular driving-shaft D,`. having keyed thereon a bevel-gear D, which meshes with eicoperat ing pinion D2, carried upon the driving-shaft' -D3which is continuously rotated. per end of the tubular shaft D is provided The upwithv a` bearing-nut D", threaded thereon and having a bearing upon the upper face of tle bracke't A?, while the shaft B is provided with an inde endent nut B7, threaded upon its upper en beneath the arm B. At the' lower end of the tubular shaft D the 'seeming-head D? is mounted in any desired manner-'lor instance, by, threading thereon. This head is shown in detail in Fig. 4 andis provided with an interior recess D to receive 'the sea ningcam C and to rotate around the same. The head 1s also provided with a circumferential langeD7, having slotted Ways D8 therein and able grooves or Ways Figs. 14 and 1 6, this block is vprovidedat opposite sides with iflan es E8, disposed in suit- 10 Within the head D5, While the under surface ol" the head is further lprovided With oppositely-disposed iianges E4 toA provide a trac or way for the roller-can ricr, Whichjis slidin ly mountedtherein. The

outer end of the b ook E is yprovided with a depending portion E5, adapted to carry suitab e stop devices to cooperate with the indev pendent member F7 of the roller-carrier. For

i instance, a setfscrew E may be threaded through the portion E5 and held .in position 4by a lock-nut E7, while the travel of the mem-r ber F is limited by means of a stop-pin F2, threaded therein and extending through an aperture inthe portion E5, whereby the outward movement of the ,member F acts as a cushioning device in the movement of the roller-carrier and for that purpose is provided withaJ cushion-block F3, of rubber or `other suitable material, disposed. within a recess in the member F and provided with a contact- 6c,

' la'te'F4 against which the set-screw E bears.

f b This member is also provided with a contactroller F5, mounted upon the inner face thereof, Where 1t is. adapted to engage a cam-finger The carrier G', tobe hereinafter describe F -is provided upon its face adjacent to this finger with a' similar roller F, as shown by detail in Fig. 15, while the opposite end of the carrier F is Vformed with a recess F7, 'within which the seaming-roller il ispivotally mounted. by means of a pin or journal F8, yAs usual in this' art, these rollers are made of different conigurations, as shown at H in to successively accomplish the diii'erent seaming actions in their operation upon the can.

-As shown in F i g. 1,a series of thebloclrs and' rollencarrers are mounted upon the head in the` present illustration g but the number thereof may be varied to suit the character carriers are actuated by the cam C in xcd themselves are rendered operative successively by means of' the -iingers G, connected ,to a shoe having arms I, which are carried at the lower portion of `a tubular sleeve I, surrounding the drivingsleeve' D of the head and adapted for a reciprocatory mobeing controlled by 'the shipper -lever I7, connected in the usual manner at I3 with a pivot upon the ring I, threaded upon theupper end of the tubular stem. The arms I are provided with groovesor ways l5, within which the carrier-sleeves' I are mounted for a reciprocatory motion in a horizontal planecoincident to the motion imparted to said sleeves are retained against a vertical a'nges I7 at opposite sides thereof, Fig. 8. The cam-fingers G are provided with a stem G7, disposed within the tubular portion E of the block and provided at their upper ends witha reduced portion G7, disposed within the'recess l of the' sleeve and held therein by means of a nut G, as shown in'Fig. 2. For the purpose of retaining these parts against rotation the reducedportion G2 of the 'fingers G is provided with a pin or lug G, adapted to seat within a recess I, eXl tending laterally from the aperture I through the sleeve, as will be seen byvreference tov Figs. 7 and v8, The iingers G are pivotally secured to the lower end of the' stem G by means of the ears G5, extending downward therethrough and,A through a portion Vof the finger. Each of the fingers used in the series of rollers is provided with a cam or Wedge face G7, and Ithis face-is disposed at ends of the finger, as shown by reference to Fig. 13, so that when the portion G7 acts uponthe roller-carrier to force the roller into operative position the rollers will be successively moved into position in the continued downward movement of the arm controlling. the same. and after eachnf the carnfaces G7 tion thereon in a vertical plane, said sleevea Y Fill', l() H in Fig. il and H7 in Fig. -12 so as D 7 C C I and controlled by the cam, three being shown of work.

movement within the arms by means of the IOS therefrom, and a pivot-pin G, extending I different points intermediate of' the opposite ISO seais/i 3 "passes the bea1ing-i'ollers upon the seannngroller vcarrier the parts are released, so to have no further action upon the can. in the l operation of the invention only one of the seamingfrollers is-in operation at a time, and as the seaming-rollers perform successive steps in forming the double seam they are successively operated by the disposition of the cam-faces upon the fingers G, as just dero.; scribed.

The shipperdever l2 may be operated in any desired manner, but is preferably automaticallycontrolled by means of a cam J, Fig. 7, of suitable coniiguration to govern I5. the successive downward movement of the .arms controlling the caindingers, said cam being mounted upon ai driving-shaft J", as shown in Fig. l. Cooperating with this cam is a friction-roller J2, carried by a casing J3,

zo supported upon one end of the shipperdever I, which lever is pivoted atei npon a suitable support-dor instance, lugs from the standard A, as shown in Fig. Peand this roller is held in contact with the cam by z 5 .any suitable tension mean/stor instance, a weight J5, suspended by means of a rod J, pivotally connected wi th the casing e 3, as at J7.

For the purpose of reducing the' speed et the driving-shaft J below that of the shaft go D3, as shownin Fig. 1 a series 'of reducing gears of any .desired arrangement may be provided. For instance, motion maybe con- Veyed from a pulley K. upon the driving-shaft D3 to a larger pulley E. upon the shaft K2 by 3 5 means of a belt K3. The shaft K2 carries a pinion K", meshing with a gear K5 upon the shaft K",which shaft has secured thereto a pinion K7, meshing with a gear K8 upon the shaft K. This latter shaft is provided with a pinion K10, meshing with a gear L, loosely -mounted upon the shalt J and adapted to be securedto rotate with said shaft by means to be hereinafter described. These means fmaycomprise .any suitable trip or clutch ymechanism, but a desirable form is herein fi'llustrated in Figs. 18 and 19, wherein the ear L is provided atene side with a hub L',

. avin secured thereon a hardened plate L3, provi ed with a series ot recesses L2, extending therethrough and into the hubL. These recesses are adapted-to receive the clutchinLt, .mounted to recpipcate within the j ub M, secured to the shaft J. This pin is provided With a head L5 and with a guideu stern L, extending through a suitable recess l .inthe hub vand parallel to the pin Ll for the' 'pu1pos`e of guiding the same and preventing` j any rotation'thereof.. The clutchpin is nor- `xliialiyheld in one of the sockets in the hub 6o TL. by means of a tension-spring L7, mounted l upon a face of the hub M in any desired mannerefor instance, by the screws Ls-and bearing at its free end upon head L5 of the clutch-head. The inner face `ot this pin is 6 5 tapered or beveled, as shown at L", to coop-V era-te With the beveled tace N oi the clutch- `finger N. This linger is mounted. in a bracket Nz'by means of apivot N3 and the beveled end thereof' rnormally forced toward the shaft J by means of a tension-spring N4, 7 0 secured at one end to the bracket and bearing at its opposite end against the lower por tion of the clutch-finger N.

During the operation oi' seeming a can the gear L and the members carried by the shaft J make one revolution, and for the purpose of controlling this motion and for automatically releasing the controlling-cam a trip-levor O is 'provided and comprises substantially a bell-crank lever having one end -,O 8o' thereof provided with a pivotally-mounted irietion-roller02 and the opposite end G3 connected, by means of a link or rod O4, with the controlling-lever ot the machine, to be hereinafter described. Depending from this bell- 8 5 cranlt lever is an arm O5, provided with a laterallyextenzling pin O6, which in the moven nient of the lever in the direction indicated by the arrow in Fig. v18 contacts With the iovier end ot the tripe'linger N', withdrawing 9o it r'rom the clutch-pin, which is forced. by the tension-spring upon the head thereoiC into clutching contact with the hub of the continuously -.f.l.riven gear L, thus imparting movement to the shaft J" and to the controlling-cam d, carried thereby. In this motion ci: the cranlclever the friction-roller is raised to ride upon the cam-flange M, carried by the'hub M and holds, the parts in this position until a complete rotation ismade, When `ico the recessedportieri M2 or" the ilange permits the parts to beretractcd to the position shown in Fig. 18, when the finger N is disposed in the path of the head L5 and automatically passes behind the same to Withdraw the pin from the hub of the driven gear L, thus disconnecting the shaft J from its driving means.

The controlling-lever for the parts just ldescribed is shown at P in Figs. 1 and 2l and is connected with the link or rod O4 by means no of a bell-crank lever O7, mounted upon a fixed part and connected by a link O8 With the con-- trolling-lever at the pivot P, which is iisposedabove the pivot?2 for said lever. The latter pivot is mounted in a depending bracket r I 5 P3, carried by the arm A5, which forms one of the bearings for the shaft Q of the can-table Q. This shaft is provided at its lower portion with a collar secured thereon by any suitable nieansfiior'instance, a set-screw Q3 1 2 o and is provided at opposite sides with pivots Q, by which it is connected With the outer end or' a lever Q5, pivotally mounted at its inner end Q to the standard A. This lever is provided intermediate of its ends vvith a pin or lug Q7, adapted to engage a cam-lever P4,

carried by the controllmgdever P,'Which. in

its movement carries the pin Q7 and the legver upon which it is mounted from the fullline position shown in Fig. 2l to that shown 13o in dotted lines, thus bringing the can into firm contact with the seamng-head. The lever P is automatically retracted by meansof the spring P5, extending therefrom to the standard. .After the raising operation is performed there is a continued movement of the lever P permitted for the purpose of tripping the clutch-pin and starting the operatinglshaft for the controlling-cam. Referring to l xo Fig. 21, the position indicated at l is with the parts at rest, at which time the. seeming-head is continuously rotated in the usual manner. When the lever is brought to the position indicated at 2, the tableis elevated to bring the can into the seeming-head, While a continued movement tothe position shown at 3 trips the 'clutch to operate the controlling-cam, which is rotated at a much slower speed. than the seaming-head and makes only a single revolution during the time required for t e several seeming-rollers to consecutively operate u on the can to be seamed.

It is )puelieved that the operation of the different features of construction will be clearly" understood from the foregoing description, and it need only be added that in the use of the machine the can is placed upon its table 'and 'the shaft therefor raised by the controlling-lever to bring the can into the seaming-- 3o head and against the stop at that point.

This movement does not start the controlling-cam, and the can can be lowered again if found necessary `as a'continued movement ofthe lever inthe same direction is required to trip the finger controlling the clutch-pin, so as-to permit that pinto seat in the continuously-rotated gear loosely mounted upon the same shaft. When this gear is clutched, it rotates the shaft and the controlling-cam secured thereto, While the configuration of this cam determines the successive downward movementof the cam-fingers, 'by which each of the seaming-rollers is consecutively placed in operative position relative to the can and after this operation allowed to retract therefrom, This action continues until the cam-flange at the tripping-finger has completed arevolution,when the clutch-pin is automaticall withdrawn, thus stopping the rotation o the controlling-cam in proper' qosition to permit the elevation of the cam-hngers by means of the Weight or other retracting means connected to the tripping-lever, by which the fingers are reciprocated. lt will be observed that the operation of these fingers is independent of the continuous rotation of the head, while the rollers not operative until the fingers are thrown into proper position by the controlling-cam. The pattern-cam, held -in fixed position within the head, is capable of removal or re )lacement, as found necessary, and controls the reciprocatory motion of the carriers for the seamin, -rollers, so that any desired-configu- 65 ration of can may be seamed simply by other parts in canine changing]r this pattern-cam ywithin the seam'- ing-hea it isfonly necessaryto operate bellcrank leverA upon the peri hery ofthe cam-flange, which will hold t e lever andV o erative osition during the rotation of thisfllange, and when the recessed portion 4of the flange is reached the lever is automatically restored to its inward position by means of the retrectin ,-spring extending from the lever to the stan ard. v

it will be obvious that changes may be made in the details of construction andconfiguration such as would be sug ested by the foregoing disclosure to those s illed in this art Withoutdepartingfrom the spiritof vthe. invention as defined by the appended claims,
