MACHINE FOR MARKING CANS.

lle it known that l.A lli-:Nur GABRIEL G1- Nam, a citizen of the United States. residing at llonolulu7 county of llonolulu. Terre tory of llawaii. have invented certain new and useful Iniprt'n'cnieuts in Machines for Marking Cans; and l do hereby declare the following to he a full. clear. and exact dcseriptinn of the invention, such as will enable. others skilled in the art to 4which it appertaiiis to make and yuse thesan'ie.

This invention relatesl to machines for niaiking cans or other cylindrical containers, either before or after filling. in order that the grade of the. contents of thc can may be known after sealing.

The objectof the invention is to produce a machine of this character which shall be automatic, continuous and eieicnt in operation.

Another object is to niark the ean in two or three places on its periphery with siniilai type, so thabat least one niark `will always appear to vieivand thus obviate the necessityof turning the can in order-to observe the marking.

Another object is to adapt the niachine so that it can be quickly altered so as to niark the cans with a different niark or to niarkV cans of another size.

A further object is to provide means for marking cans which have been dented or are slightly out of round.

Machines have been made for marking either the top or bottom heads of cans While conveyed by a link belt or wire rope. The ordinary1 method, however, is to stamp thc v,can by hand with a rocking motion of the rubber or other type on the cylindrical portion of the can, usually iii a single placeonly. the marking indicating the contents of the pack. which afterward covered b v a suitable label. i'

Wvith lthe above mentioned objects in view. my invention consists in the novel arrangement and construction of parts as .hcrwafter described and' claimed. refer- 'cnetA Aoeing had to the aeeouil'iaiivingdrawings. forming a part of this speciticatioin in which corresponding parts inthe several figures arcdesignatcd by like charactersl ot reference. i

invention in a preferred foi-in. Fig. 2 is a similar view of a portion of the maehiiic shown in Fig. 1, illustrating more fully the means for impressing the cans against the tvpe wheel. Fig. 3K is a front elevation of the machine. Fig. 4 is a rear view ot the' niaehine. Fig. 5 is a sectional view on thel linc'A-B of Fig. 1. Fig. 6 is an enlarged view of a portion of' thc face of the. type' wheel. Fig. 7 is a longitudinal"section through the center of Fig. G. Fig. 8 is a transverse section on the line C-D of Fig. (i. Fig. 9 is-a plan v"iew of the inking roller and the fork which supports the sanic.

Referring to the drawings. the body 1 of the machine -is preferably a casting and.70 provided with flanges 2 and 3' at its front,l and rearrespectively for supporting the machine upon transverse wooden beams' 4. In the bearing 5 at the top of the hody'l is journaled the shaft G. `A sprocket wheel 7. and a pulley 8 are secured to the sliatt. (i on opposite sides of the bearing The lsprocket wheel 7 is provided-witha sleeve or offset hub 9 on the side opposite to the hearing 5. A wheel 10 of'wood or other 80 suitable material vis reniovabl)r secured on the sleeve or hub tl by nieansof-tl'ie washer 1l and the nut .19. the. end of-the shaft t being threaded to receive-said nut. A piiiA` 13 in the sprocket wheel 7 engages a hole 14 in the wheel 10. so that this wheel is revolved with the shaft (l, Fig. 5. The wheel 10 is'preferablv provided with two flat. traction rings l5 1G Of'rubber or other material. also with a plurality of rubber or other suitable type 17- secured at: intervals between said rings to the cripheryof this wheel. as shown. `The thickness of the type l? is greater than tliatof the ti'aetioii'rings l5 lt. Figs. 7 and 8.

'.lwo flexible band-s 18 1t) -ot rubber belting or other suitable material are provided. their front. ends heilig attached to the lug Q0v of the body 1 and their rear ends to the lever ll respectively. The lever ll is' fulerumed on the pin 22 secured in the bossv 23V of the body' `1.v The. ends ot a tension spring 24 are connected to the lever il and to a hook in the bottom of the/hotly l, such that the bands 18 19 are norn'iallv. tightened in a horizontal position. Fig. 1. The distance between the bands 18 19 and the wheel 10 is made less than the diameter bars are fastened to the angles 26 v27 respectively. Upper guard plates 32 33 and a side bar 34 are attachedv to and supported by the frames 30 3,1, as shown.

The ink roller 35 is mounted to turn on the pin 36 in the fork 37, Fig. 9. The fork 37 is provided with a hub 38 which is piv-y oted on the pin 39 secured to the boss 4Q at the upper rear portion of the body 1,

Figs. 1 and 4. The ink roller 35 rolls on the distributing roller 41 and on 'the type 17 on the Wheel 10. The distributing roller 41 is attached to the sleeve 42 of the sprocket 43 .which is mounted toturn on the pin'44 secured to the boss 45 of the body '1, Fig. 4. The sprockets 7 and 43 are connected Aby a link -belt 46. The ink well 47 is secured by bolts 48 to the body 1, such that the rollerv 4l may revolve with a portion of said roller in ink in said well.

In operation the machine is driven in the direction as shown by arrows by means of a belt applied to the pulley 8. The cans to be marked roll down on the inclined angles 26 onto the flexible bands 18 19 and against the traction rings -15 16 on the wheel 10, which in revolving cause the can to continue rolling rearward, the flexible bands 18 19 beingr deflected from their normal horizont-al position, and against the action of the spring 24, by the passage of the can or cans under the wheell 10, Fig. 2. During this passage under the wheel 10, however, the can has revolved about two-thirds of a revolution and has been successively impressed by two or three of the type 17 which have previously been inked by contact with the roller 35. The cans thus marked are pushed rearward by successive cans and are discharged from the machine by rolling down the inclined angles 27. The markings on the cans are not blurred by the adjacent cans, however, as the flanges of the heads prevent coutact of the bodies with one another, The flexible bands 18 19 are placed far enough apart so as to clear the markings on the cans. `Although the can may be dented or lslightly out of round nevertheless the flexible bands 18 19 force the can against the type 17 and produce the desired markings on the can in not less than two places. When "it is desired'to change the mark, for example from the B grade as illustrated to some other grade or mark, the wheel 10 is easily replaced by. a similar wheel with the desired type. "Vhen smaller cans are to be marked, a Wheel 10 of a suitable larger diameter and a slightly smallerv ink roller 35 are employed, the change being easily and quickly made. f

The cans may be fed to the machine either by hand or by a suitable conveyer in a Well known manner.

While the machine has been described and i 'roll while in engagement with said type wheel, said trackway comprising a flexible band `fixed at one end, and means acting on the other end of said band to yieldingly opy pose a deflection of said'band by the cans.

2. In a machine for marking cans, the combination with a type-wheel, of a trackway on which the cans are caused to roll While in engagement with said type-wheel, said trackway comprising a flexible band fixed at one end, a movable element to whichA the'other end 1s connected, and means acting on said element to exert a tensile stress on said band thereby tending to keep it taut.

3. In a can marking machine, a "typewheel, a support for the cans adapted to hold a plurality vof cans in contact with the type-wheel, said Support comprising a ilexible band fixed at one end, a pivoted lever to which the other end of the band is connected and means acting on said lever and tending to turn it around its pivot to exert a continual tensile stress on said trackway.
