To all whom) it may concern Be it known thatfI, FRANK J; SMrr' a citizenof the United States, residing in lief :-ity and county of San Francisco and-S of California, have 'invented new and firs fication.

Myinvention relates to that classof Inachines,'especiallyadapted for nse in' can-' neries', by which the top-heads are placed upon and double-seamed to the upper endso'f filled cans. a

- 'Theobject of my invention is to provide a simple andefi'ec'tive machine for this purpose, and to-this .end my inventionconsists in the 'novel constructions,- arrangements and combinations which I shall hereinafter fully describe and claim, byreference to the ac- .coinpanying drawings, injwhich 7 j Figure 1' 1s a front View .of my machine.-

Fig. 10 is'a'plan of thesame, with the upper parts omitted. Fig. 11 is a fragmentary sectional View of the can-he'adfeed mechanismon the line y y of Fig. 5; The frame of the machine is composed of the pedestal 1' and its superstructnrefi. 1

This clamping disk 13, also has V notches li in Its perlphery seen best in.Fig. e andwill be explained later; As one of these notches 14 register the entra'nce of the inlea'ding canway 3 a can is'pnshed alongsai'dway by the finger 8 and as the can-begins'r'toenter notch-14L the clamping disk 13' beginstorevolve, and the can-carried by the finger 8 1s gradually placed in notch 14 withouthavingfslackened its forward motion, the can makingbut one, stopfrom the time it is placed in the canway 3 until the cover is seamed-to the can, this. stop being where the seaming takes place, thus preventing the loss of liquid from the can caused by the s idden starting and {stopping as in most other ma- 'ohines,'-designed for doing this class of work. The shaft 12 also carries, at its upper end, a can head table 15,wh-ich asshown .i'n'Fig t, is a disk-with four holes16, the

.By-reference to Fig. (3,.it will be seen that the-hole 1 6 of the can-head table has a ledge 17 uponwhich the flange a can head l8; rests, 'w-herebysaid head is temporarily supported 'in the table;

When this particular head has been moved by the table 15 to that .stationat which the can has entered a notch of'the can-clamping disk 13, said head will be directly above-said can, in the relative. position shown in Fig. 6.

Tlie'means fohsnccessively feeding the can heads-.18 to their seat 17 in the hole 16 of the can head table 15, are shown in Figs. l-to '6, and in Fig. -11.

The presser plate 2.6 at this point begins to raise and the-plunger inovingstill higher litts the can with its head held firmly uin place'out of andabove its rest in the canhead table 15, as shown in Figs; 2- and 3, .to -aposit-ion to be'operated on by the seam-' ingrolls' Asthe-can begins to rise with the upwardmovement of'the plunger 5,'a semi-circular clam'ping'ja'w 28,-.wl1ich is th'ecomplem'ent of the semi-circular notch 14, and also the 'V notches 145', bywhich one side of thecan in 2 toward thecan until the can-is pere s e fe'ct-ly sea'ted in the-clamping disk 13 andthe' V notches' on the clamping jaw are loosely seatedin theV grooves in the clamping d1sk,.but not so tightthatvthe can will not easilyslide through. Atthis pointthe 'roll 66 reaches theperpendicular,partof the carh track67. The plunger continues to.

rise to its full height, but just before reach-.

' 'The sea-niing device, as seen in Figs'Q, 3, 9and lOco npris'es the head 29, to'which is. imparted a .continuousrrotary-movement. .In this. head arejournaledat diametrically opposite points; as seenyinFig'. 10,.the short rock shafts 30, the lower ends of which have clamps 31, in'the free extremities'of which are carried :the grooved sea-min rolls 32.

IWhen these rolls are thrown; inwardly by ing its highest point, the V- shaped roller 72 enters the V shaped groove in the adjustthe rocking of the shaft 30, they. press'upon and bend inwardly the flanges of the headand can body and affect the doubleseaming in the general'manrier, wellj known to 1 the art. 1 i

d en the-seaming is completed the rolls swing outward, and the plunger 5 descends to its normal lower posit-ion, The next movementof the can-clamp disk 13 carries the can from the plunger head 4 to the table 3 again,and said can is, directed to the outleading can-way 6 by the rail 10.- 1 I ,From the foregoing description'the operatlon of the machine W1ll now be um:le1"st ')od. It will be seen that, assuming intermittent motion, that is, acycle with stated period of-rest, a can-head dropped from the c ol-' umn, is carried by the can-head-table 1510 aposition at which a can enters into regis-. tering notch '14 of the can-clamp'.disk 13.

The next movement carries ,th e'f head'and 1 15 can to the next station, where during the period-ofrest from rotary motion the can is lifted intothe head, is pushed, up farther with its head into the plane of action of the seamer rolls, is there clamped rigidly circumferentiall'y against rotation, cover and can being held firmly together by the pressure of the upper plunger head 26 and the lower plunger head 4, andwhe'n this clamp- .ing and holding of the assembled heads and 1.25

cans is complete, the revolving seamer rolls. performthelr funct on. of double seaming. 7When this is-done, the headed can is lowered, If the can sticks to the presser plate 526, as isoften the case, the underside of the 4 I now be described.

With. these parts and their operations thusmade clear, the operative connections will Referring to Fig. 2, poweris ledfinto the "machine by the shaft T 3. In the frame ismounted f the verticahm-ain shaft 34, from. ,w-hich all movements, except the rotation of the scanner head, are derived. This main,

shaft 34 is given motion throughaworm 35;,-

shown-. Fig 7, on theinleading power.

which are here'divided into four equalsec- -tlons, separatedby' concave-face locking .segmcnts 38. Upon a short counters'haft 39,

is mounted a mutilated pinion i0, the

toothed portion of which is adapted to engage with the toothed sections of the gear 37, and it's smoothportion is adapted to fit.

and engagetheconcave'locking segments 38,?

of said gear. It'will be seen that by the pr'oa Y portions indicated in Fig/7, the gear 37 willbe moved through arcs ofrotation, with intervening periods of rests in-which it is locked by, the; engagement of the -smooth portion of'the'pinion 40 with .the concave segments 38' ofthe gear. .Motionistrahsmitted' to the pinion 40, as shown in Fig.7,

by means of a sprocket 41 on the.c ountershaft 39, the chain 42, and the sprocket 43, on the main shaft 34:. ,The can-feed fingers 8 by which the cans are pushed into the notches of the can-clamp disk 13, are driven as follows. These fingers are carried bya chain 9,o ne end of which, as shown in Fig. ismountedupon a terminal sprocket 4: 1, on a countershaft-45. This shaft carries a sprocket 4.6,; from which a chain-47 passes to a sprocket &8 on the main shaft'34. The.;can-head feed operating mechanism .is best seen Figs. 5, 6 and 8. The slide rests 23 which by their projection and withdrawal control the can-head column and the feeding of the lowermost head to the can'- head table, are provided each, with a stud 49. These studs play in cam slots-50 made .in an oscillatory ring 51 which is seated upon the pivoted table 19 by amounting adapting it to be oscillated. The cam-slots l 50 in the ring are soshaped as 'shown in Fig. 5, that when'said ring is moved in one direction, one pair. of Islide-rests will be withdrawn and the other pair projected and vice .versa, with the effect heretofore deof a; section of teeth 52 on its periphery with which meshes a-t'oothed sector 53 carried on the upperend of the rocking pintle 54, which passesldown through the hollow pillar 20. On the lowerend of the pintle et'is a crank 55 seenin Fig; 8, to-which I IS connected a rod-'56. The other end of the rod '56l-is 'connectedl with a forked sliding *piece: carrying a roller 57, which playsin the-cam 58 m'ounted on the main shaft 34.

The plunger 5' is pivoted at 60. One of the ends of the lever is connected with .link 61, which is connectthe projection 64 is provided-witli'a guide roller 66-which-plays in a fixed cam-way 67 onthe frame of the machine. As the plunger .5. rises from the position in which it is shown in-Fig. 2, it will carry the guide roll 66 and itsclam'ping aw 28 withit, and as Jthe-roller'f 66 travels up theincline of the cam-way 67, s'aidclamping jaw will-be swung inwardly and up to the can, as is shown in F 3. 7 The extent of this pres- ,sure 'maybel determined by adjusting the bolt 68. The seaming head 29 it Jarried by shaft 73 which is mo'unted on a frame and. to'which continuous rotation imparted by the bevel gear- 74 onits upper portion and the bevel gear 75, on the power shaft 33, as seen in Figs. 1' and 2. 'Mounted'to slide vertically upon the shaft '7 J is av shifting head 7 6', which has on opposite sides the vertical ways 77, shown in Figs. 2 and 3, and in dotted lines. "in" Fig. 9.- The seaming- =head 29 has side brac'l'ets,78,'in the upper ends of which arefrock pintles 79.. Secured upon these pintles are cranks '80 in the outer ends of Wh-lCll are rollers 81, which play in the ve'rtical ways 77 of the head 76. I From the above arrangement it, will be understood that during the down stroke oi the l1ead, 7.6, the roller, 8l, will ride upon theupper walls of the guide-wa v. 77. and into the vertical portionof this guide-way describing a circular path .and that in ,the return movement of the" head, 76, the roller 81,.will come incontact with the lower \val of the guide-way, 77, and thusassume tht position-shown in Figs. 2and 3. l

'Upon jerock pintle 79 are also securec'. the downwardly extending cranks 82, tlu lower ends of which are forked over stud: 83, as seen in Fig. 3. These studs are se cured to bearings Set. which are connecte't with sliding sleeves 85, Fig. 10, mounted i1 scribed. The ring 51 is oscillated by means bearings on the upper surface of th .lifted and lowered by :the' means shown in Fig. 59 is a levercombination-of a fixed'table and 'intermit 1'eaminghead29, said sliding sleeves being m'ounted upon rods-86",which rods are connectedat. relatively "oppesiteends, to the jcranks'86 on the upper-ends of-the rocker .5 shafts-3O of the seaminghead. These rodshave secured upon them at each-end,'a nut- 84, wlith which theends'ofthe sleeves contact, thereby moving said rods. Itwill now be seen that as the shifting head 76nis raised i lo'and lowered the seaming rollers will be thrown outwardly and withdrawn by the rocking of the shaft 30. The limits of the throw of therollers may be varied by adjusting the nuts 8 on the rods 86f,

One end'ofthislever is forked and piv- 'otally connected toa. roller which plays -in' .1 annular grooye 90, in the shifting 'head76, .20. Its other'fend has a roller 91, .whichplays'in the-cam 92 onjthe main shaft 34:. The upper .plunger head 26 has its stem 27 passing up through and .slidablymov-able in the shaft 73 .of the seaming head 29, and said plunger headstem 27 projects from'the top of the ma hine, as seen in Figs. 1 and 2.
