Application filed March 2. 1909, Serial No. 480,963. Renewed September 20,1910. SerialNo. 582,92 1r ZL'o'aZl whom it only concern:

Be itv known that I, FRANK Prrrls RYDER, a citizen of the United States, residing .at Boston, in the county of Suiiolk, State of Massachusetts, have inventedcertain new and useful Improvements in Can-Marking Matioihrefergaice being had to the accompanying 'd1'a \\'ings ,jtornnnga part, hereof.

in'unbei-ing machines designedfor'i se with eainii 11g inachin ery and the purposethere-' of is to stamp or print: a certain word, numberor mark upon the cans some't iinc nifmber or mark willindieate the kind goods, grade, or other features of the'eontentsot' the can; the-purpose of this mark being toe'nabl'e the subsequentidentification of the cans upon which it is printed, and not for the purpose ofserving as alabel to inform .purchasersot the contents of the can. v

lVith theabove purpose in view, my inention consists in the construction and combination of elements .hereinaftcridescribed and p rticnlarl pointed out in the claims.-" i

In the accon'ipanying drawingswherein Ihave illustrated an embodiment of my invention: Figure 1 is an elevation of my improved can marking machine "as seen looking along the line in which the cans travel, the movement of the cans beingtti; ward. t-he observer; Fig. 2 is an elevation of nymachine. as se .from the right; of Fig. 1, the-movement of the cans 'bein toward thele'ft; Fig. 3 is a plan view' ih s v rating so] much of my machine as lies below the planeintlicated by the line A-B Figs. 1 and 2, the movement of the cans being toward the left; Fig. 4 is a sectional view taken in thehorizontal planeindicated by the line C.'D, Figs. 1 and .2, certain of the parts, however,- being omitted for. the

view showing the arm for supporting a stamp or type for marking the cans; Fig. 6

whereby the type supporting armshown-in Fig. 5 18 carried; Fig. 8 1s a View .of a cam above referred to; Fig. 9 is ,a view showing the dam shown in F ig; 8 developed "ind, Fig-'10 is'a'view's'howin a different form of turnstile 01' star whee employed in'my dvice." f In the drawings 1 and 2 represent portions of the bed of my machine forming a part of canniiig apparatus and to'which it is desired to attach my marking machine. It will be understood that 'these elements may be a part of 'oneof the numerous eonveyers" commonly "used in canning fplaiits, 101- the'y" may "be tracks provided for the.

express p irpo's'e of forming a support for niy device."-

My improved Iiiarking machine is adapted for rise in any locationpastw1i1eli 'ca1is are The elements 1' at-.152 fwilhoi-dinarily be providedwith-guide strips 3 and kbetween v which the cans pass, as will be understood from Figs llandil; and 5 is a feeding chain havinga'series :o'f'slats 6 attached thereto which travel over the upper surfaces'of the members 1 and 2, and upon which slats the .cans' rest, certainof said slats being provided Withlug'S 7 to engage and move the cans along; 'lhdelemeu'ts thus far de-' scribed, while they'are-present in many niachincs usedin'thc canning business, will be seen to form in-ciieet a conveyor by means of'which t-herans are caused to travel pasta given Joint, at which point my ca'n markinir mac iine will be located.

ityflcan marking machine is shownassecured to the member 1 by means of a bracket 8, the uppersurface of which. is provided with" a groove Q'Whereby my machine may be aadju st'ed' transversely to the members 1 an 2. j

10 represents the main frame of my ma? cliinefwhich frame serves as a supportfor star wheel is provided with projecting arms and, with depressed intermediate portions 161 which may be shaped to conform substantially with the periphery of the cans to be operated upon as shown in Figs. 1 to 4; or the element 13 may take the form shown in the modified type of star wheel shown a 5 in Fig. and this turnstile or star wheel is so adjusted as by moving the frame 10 upon the braeket 8 that the arms project over the eonveyer along which the cans pass; so that successive cans will engage the 10 arms 15 as they pass along and thus rotate.

"the turnstile 13, as .will be understood from Figs. 1 and 2, in which the cans are shown in elevation and in dotted lines, and from Fig.3 in which the cans are shown in plan. 15 16 is a gear secured to the turnstile 13, and 17'is a vertical shaft supported in bear ings 18 carried by the frame 10."

19 is a pinion upon the lower end of the shaft 17 and in mesh with the gear 16. 20, .20 is a collar for supporting the shaft 17.

21 is a horizontal shaft driven from the shaft 17 by means of gears 22, 23, the gear 22 being twice the diameter of the gear 23 so that the shaft 21 is driven twice as fast as the shaft 17, which shaft 21 extends inward to a point adjacent the cans to be marked and carries at its inner end the printing or marking mechanism hereinafter described. This shaft 21 may be supported in any suitable bearings carried by the frame 10. I, however, as a preferred construction, mount the shaft 21 in a vertically adjustable supporting member 24 which is shown as provided with a square opening 25 through 3 which a correspondinglyshaped portion of the frame 10 extends. In the construction illustrated, see Figs. 1 and 4:, the shaft 21' extends through the frame 10, and an elongated slot .26 is formed therein the upper end of which'is shown-in Fig. 1; the frame 10 being shown broken away to illustrate this feature.- The supporting member 24 'is secured in position by means of a set screw 27, and the gear 22 is freely adjustable upon the shaft'17 to bring it into mesh with the gear 23 after the supporting member 2+t is properly adjusted and secured in position. 28 is a set screw for securing the gear 22 to the shaft 17. The shaft 21 is piovidedadjacent its inner'end with a collar 29 which bears against,

the endof the adjustable supporting member '24, and the inner end of said shaft is provided with an axially extending slot as shown at 30 within-which slot the printing mechanism of my device is secured. This rinting mechanism comprises a bell-crank ever having a longer arm 31 and a shorter arm 33 extending at substantially a right angle to the arm 31, said bell-crank lever being pivoted within the recess 30 by a pivot at 34: extending transverse to the axis of the shaft 21 and preferably at right angles thereto. The longer arm 31 of the bell; crahk lever extends or projects to a considerabledistance beyond the inner end of the shaft 21, and, whil said lever is carried by and thus rotates with the shaft, it is movable relatively thereto and is free to swing. about and upon the pivoted connection at 34. In the preferred form -of my device shown wherein the axis of the pivotal connection at 34 extends at right angles to the axis of the shaft- 21, it will be.seen that the bell-crank. lever will swing in a. plane passing through-the axis of said shaft. The free outer end of the arm31 is recessed or slotted to receive a type or stamp 32 designed to come' into contact with the cans to mark them as they pass along as will be understood fr'omFig. 1 of the "drawings.

35 is an arm secured to the inner end of the shaft 21 and which forms an abutment for a spring 36 acting upon the shorter arm '33 of the printing mechanism to force said arm away from the abutment, and, as will be understood, to thus swing the bell-crank lever 31, 33 about the pivot 34 and bring'thc type 32 at thefree end thereof into contact with a' can to be marked. Holes are'pro- 0 vided as shown for receiving the ends of the spring 36.

37 is a rotary ink padfrom which the type or stamp 32 receives its ink, and 38 is an arm whereby said ink pad is supported, said arm in the form of my device illustrated being secured to the frame 10.

39' is a cam member, for controlling the action of the printing mechanism above disclosed. This arm member is shown as located upon the inner end of the adjustable supporting member24, in which case it will move as .the same is adjusted vertically and will always be concentric with the shaft 21, and said cam is shown as an element separable, from said supporting member, although it may obviously be formed inte' rally therewith. The-cam member is a nular in form as.will be understood from Figs. 2 and 8 0f the drawings, and is provided with two depressions 40 and 41 in its operating surface, each of which depressions includes'an abrupt shoulder at 42 or 43 extending from the operating surface of the cam to the bottom of the depression40 01-41,

and an inclined surface leading from -the bottoms of the depressions upward, as will be understood from Fig. 9 of the drawings. It will however be understmd that the form of these depressions is of secondary impor- 12o tance, so long as the functions hereinafter ascribed to the cam member as a whole are carried out.

The shorter arm 33 of the bell-crank lever bears against and slides over the surface of the cam 39 as the shaft 21 and the lever car.- ried by itis rotated as above explained and, as the arm 33 passes beyond the shoulder 43, the spring 36 willfbrce said arm into the depression tland swing the longer arm 31 about the pivotat -34Ia1id bring the type 32'into contactkwith "a can, all as will be understood from Figs; land 9 of the drawing. As-theshaft 21 and lever 18 rotated farther the arm 33 rides up the incline from the depression .41, and,-when it reaches the second depression 40 is forced thereinto by the spring 36'to thereby bringthe type 32 into contact with the ink pad 37. The abrupt 10 shoulders of the depressions wand 41 will,

it will be understood, permit a quicknrovement of the type 32 into contact with the ink pad and the can, while the inclined surfaceswill cause the type to be swung away from' the pad and can as the arm 33 is carried forward bythe rotation of the shaft'21 more slowly, and: without. possible injuryto the parts as would'be the case if the arm were forced against an abrupt zshonlder. The constructionof my. can markingma chine being as above disclosed, the operation thereof is as followszCans are fed-along the conveyer formedlby the tracks land-2,

and the feeding chain 5, the direction of movement being from right to left, Figs. 3 and 4. The cans engage and operate the star wheel or turnstile 13, which operates the shafts 17 and 21 through the gears 16 and pinion. 19, and the gears 2-2, 23 thereby rotating the shaft 21.carrying the printing mechanism, therotation .imparted thereto being-in a clockwise direction. As the shaft 21 is rotated the arm 33 of the bell-crank lever 31, 33 moves over the surface. of the 3503111 39 until said arm reaches the shoulder 42- of the depression 40, when the arm 33 will be forced to the left by the spring 36, This movement brings the type carried by the arm 31 into position to engage the ink pad 37 and said type will engage and rotate the ink paid the shaft 21 continues to rotate; and will finally be moved away from the ink pad as the arm 33 moves up the inelinc leading from the depression 40. The 45 bell crank lever 31, 33 is now further rotated until. thearm 33 comes to the shouldcr 43 of the depression .4-1, when the arm 33 will again be. forced to thcleft by the spring 36, the type this time being forced against the can to be marked. uring furtheir rotary movement of the shaft-- 21 the arm 33 moves up the inclined po'rtionof the depression 41,'\\'hereby the type carrier is moved away from the can. R 5a The form of the depressed portion 40 of the cam 39 should be such that the type will move for some little distance in contactwith the ink pad 50, while the form of the depressedportion 41 should permit as brief a 6 contact as practicable of the type with the cans. I. however, have so proportioned theparts of my machine that the type carriers .32 when in contact with the cans move in -'thcir patl1 of travel'at substantially. the same speed as the speed at which thecans move forward; sothat the type may bein a contact with the cans for quite an appreci .able' time without blurring, as there is then substantially no relative movement between the type and the eans. 1 ,There being a single printing device carried by'the shaft2l,and six arms upon the- -t'irnstile 13, itvvill be appreciated that the shaft 21 must rotateisix times .as fast as the turnstilein order that every can may be marked. I therefore make thezratio of the gear 16 and pinion 1.9 three to one, and

the ratio of the-gears 22,23 two-to one. j

.Themachine as illustrated is obviously intendedto operate upon a de'finitcsi'ze of can, both asto'diameter'and height. The

capabilityof adjustment of the frame 10- transversely and of the carrier 24 vertically is to adapt themachine for other sizes of cans.

In-case thediflercnce of size is-considerablc 35 I may use a. second turnstile or star wheel of larger diameter in place of. the one' shown; g

Havin thus described my invention and;

explained themode of operation thereof, I
