CAN-LACQUERING .ii/:actan Specification of vIl'iettexs Patent.

Application led vDecember 5, i908.I v Serial No.- 466.0166.

To all whom it may concern:

Be it known that I, `FREDmzIoK W. WILD,

J r., citizen of the United States of America-,

residing at Govans, county'of'Baltimore, State of Maryland, have invented certain new and useful improvements in Can-Lacquering Machines, of which the following i'swhich the machinefis rendered more'efli-l cient, its output increased and the quality of its work improved.

Though the mechanisms which l'are the scribed in connection with a machine which mayv be correctly termed an improvement r upon that of the'patent cited, these mechanisms may be otherwisel associated within the scope of my in/vention.

...The machine of "the patent, briefly described, consists of ways for the cans, an endlessA travelingbelt parallel to the ways and engaging the cans to rotate them, whereby they are advanced lalong the ways, one or more rotating lcylindrical brushes,the axesv of which are'parallel'to the Ways, and means for feeding liquid lacquer, paint, etc., to the' brushes. The brushes rotate in contact with the heads ofthe moving cans, coating them with the liquid. Pads or mats of absorbent material to which the coating, liquidis 'fed are placed lin the path of the cans. These serve to apply the coating to the canbodies.

By means of the spacer,fadmission of the cans to the machine is timed and ,they are properly spaced in their passage alongthe ways, In this way, manyY defects in the operation of'previous machines, as injury to the cans due to Contact between them and irregular distribution 'of the paint or lac- `quer which occurs if the cans are irregularly 5.0 or too frequently presented, are overcome.

To maintaincontiniious contact and uniform pressure of the conveyer belt ,upon thej cans on the ways without injuring the -cans `or unduly checking' their advance, yielding subject matter of my invention are de 'My invention provides an automatic'spacing device at the feed 'end of the=mach1ne..

resilient belt guides are provided. These engage the belts directly over the'cans which `are being treated and depress 'the belts into operative engagement with the cans. At the feed end of the machine, the ways are downwardly inclined so that the cans are propelled into the machine by the force of gravity. As they enter, rthe cans are conducted to a point below the level at .which they are presented to the brushes. A springv placed 'at the lowest point of the ways is compressed by each descending can and as the'down'ward tendency .of each can is checked, the spring expands or reactsand Patented frei., imma throws the can upward against the conveyer 4 f belt and on to the absorbent pad which is between the waysand extends above them.,

when 'not compressed'by the canf lf the 'first contact betweenrthe cans and the belt were uncertain or pressure of the belt on the can vgradually applied,. a considerable amount of slip would occur and the cans would not mount to the pad. By the device of my improvement, firm contact is made immediately whenfa can is brought into engagement with the belt and the can driven 1n rotation, by virtue of whichv rotation it advances over the pad 'and ways.

In .order that Vcans of various sizes may be treated, the conveyer-belt, pulley and guides *aremade adjustable vertically relatively to the ways. Each of the. cylindrical brushes which act upon the heads of the cans is, with its apron, pulley,` etc., adjustable similarly to the conveyer, and also laterally. The ways are also adjustable tocans of different lengths.v yln this way, it is made possible to adjust the' conveyer to admitv cans' of any size. to the ways and to place-'the brushes with their axes in the plane ofthe centers ofthe cans being treated, of. whatever size they may be. ,y

Each brush isactuated from the conveyer belt drive by a transmission belt which engages a pulley journaled on theconveyer frame and aysecond pulley on the brush shaft. As the distancebetween the brush frameand conveyer frame, and, therefore,

between .thetwo pulleys, varies when thel machine` is adjusted to cans of different sizes, some` means must be Aprovided to keep the transmissiony belt tight. This is accomplished by means of yan idler engaging the belt and carried by a spring pressedarm `pivotally mounted on the shaft of one of the transmission pulleys. However, the idler spaced above the pad by. a distance such that the extremities of the bristles engage the bodieslof the passing cans.' As the cans advance, the zone ofcontact moves from one end of each canV to the` other and the entire surface of the body of the can is acted upon.

by the brush. Sufficient of the paint or other liquid coating material is conveyed by the cans from the forward brushes to the rear brush and pad,`and the rear brush distributes the liquid thus suppliedin an even layer upon the can body. f

Other features of my invention willbe" hereinafter described and claimed.

The accompanying drawings illustratea machine for applying liquid coating to cans. `This machineembodies the subject matter of my invention.

Fig. .2a is an. enlarged view in the plane.. of Fig. 2,:-showing the ways with a can thereon in operative position. Fig. 3 is a sectional elevation ofthe machine taken on a longitudinalI plane which is substantially central. The rear brush is so adjusted in this view as notto be cut by the plane of section. rThe .forward portions and the pedestal of the machine are broken away. Fig. 4 is a perspective of--the vdelivery end of the machine. Fig. 5 is-a vertical section through the' belt tension. Fig.- 6 is a perspective of the brushes with their journals, supporting frames and aprons. Fig. 7 is a sectional plan of the ways at the feed end. Fig. 8 is a perspective view of thel feed'or `forward end of the machine. Figsj9 and 10 are detailed views ofthe spacing mechanism at successive stages of its operation. Fig. 11 is a plan ofthe feed end of the machine showing the spacing device.

The 'can lacquering machine illustrated in the drawings consists of a 'pedestal '-1 on which are mounted horizontal bed-rails 2 parallelto each other and extending in the direction in whichl the cans are to4 be fed# The various brackets'supporting the dierent moving parts of the machine "are secured to the bed-rails. Theways to be described grooves 8'.'

are supported by means of the brackets 3 (Fig. 2A) secured to each bed-rail near each endand near the center. vThe brackets on the two rails are in pairs, the members of leach pair being one on each rail and oppo with depending brackets 6 carrying at their .lower extremities hubs 7 which receive the 4'rods 5, and are secured thereto lby set screws 9. The rods are grooved at- 8 to seat th'eset screws in a plurality of positions of the hubs..

Each bracket 6 is provided with a lug 11 vwhich is 'apertured to receive an upright post 12, to the upper extremities of which posts the guide rails 13 are secured.- It is apparentthat ,the rails and side guides can be adjusted laterally to receive' cans of various sizes.v This is accomplished by moving the hubs -7 'of the arms along the rod 5 and tightening the set screw in theirproper Between the rails and resting on the horizontal arm ofthe L are pads 14 of absorbent material. These pads are resilient and normally theirupper. surface is above the up- ,right portion of the L-shaped rail 10. 'By

reference to Fig. 2A, it will be seen that these pads are compressed by the passing cans so 'that the edges ofthe cans rest onuthe top surfaces of the rails. At the forward end of the machine, a bracket 15'is secured to each bed rail 2, and npivoted to the upright arms 16 of the brackets 15, to swing about a horizontal axis, is a trough 17 for the cans. rlhis trough is supported during the operation of the machine by the removable rod 18 which engages the trough near its outer extremity and extends downward to the forward end of the base of the machine. The trough-17 is considerably wider than the length of the cans to be treated; Secured to the upright sides 18 of the trough near its forward end (Fig. 7) are leaf springs.19,.wh1ch extend backward and are bent inward toward'the center of the trough. The tension and position of these springs is adjustable by means of screws 20vmcunted in threaded blocks 21 on the trough.- In its norma-l position, during the opera-tion of the machine, 'the main body ofthe trough is inclined downward at a slight angle to the horizontal. At a point slight-1y beyond the rearward' extremities 22- of the springs 19, this angle is increased and the incline of the trough toward the machine is made steeper.

Forward of the brushes, the upright portion 25 of the L-shaped ways 10 is removed,

(see` Fig. 8) and these ways are inclined,

. by a horizont-albar 4 3 (see .F ig.

eaafeai feed end of the machine, forming the de- I pendingarms 48 are rigidly secured. These pression 27, and then upward to meet the rear extremity 26 ofthe trough 17, forming the incline 28. A leafspring 29 is'secured to each rail 10 at its forward'extremity and ex'tends downward." to the rear over the dei: pression 27. These springs are deflected up ward at a slight angle from the ways for a purpose to be hereinafter described.

The pads 14, to which reference has been made, extend backward through the machine from the depression 27, and: are supported laterally bythe upright portion; of thevL- shaped ways. The pads are stifened by a sheet of metal 23y which rests on -the' hori zontal portion of the ways. F rom-a point just beyond the depression 27, the ways 1() are substantially horizontal for a distance equal toabout'a third of the length of the machine, to a point marked 24 `beneath the rear piilley 47'A in Fig. 3. From this poi-nt tothe rear extremity of the machine, they are inclined 'downward at an angle of about 150. At the rear end ofthe machine, (see Fig. 1) is atrough 30 pivoted at its forward extremity to the bed rails2 and supported at the rear by means of a rod 31 which is secured atits lower extremity tothe base platefof the machine'. Securedfto the forward and central portions of each bed,rail

2, -(see Figs. 3 and 4) is a bracket 32 in" which a 4vertical rod 33 .fis mounted. .These rods are four innumber. Each rod is adjustable vertically and is secured in adjusted position' by means of a pin 34 which passes 4througha hole inthe bracket 32 and a suitable vlioleof-a series35 in the rod. 4The rod 33 is ni'arked witha series of numbers 36 tol correspond 'to-the holes and indicate its ad.

justed position. Secured to the upper extremity ofeach rod-33 is ing a bearing 38. .i

ITwo shafts 39'extending transversely of the machine are journaled at each end in the 'bearings 3 8. The rearshaft 39 is driven by a 'suitable means not shown. Secured to this shaft near its kcentral portion are t-wo pulleys 40 of equal diameter. Two similar pulleys 41 are mounted on the forward shaft 39 and'conveyerv belts 42 run over the pulleys 40 and41.. The 4forward and rear brackets 37'at each side'. of the machine are connected l Each end of the bar 43- is provided witha depending arm 44 rigidly secured'to the rod; Shafts 46 are mounted in the extremitiesof the horizontal arms ofthe brackets 37. The lower extremities of the depending arms 44 at each en d of the machine are apertured to receive the shafts and mounted on these A shafts are guide. pulleys 47 which4 depress the belts 42 to the plane of the upper surfaces of the can bodies on the horizontal portions of the'ways. Between the extremities of the bars 43 at the desired intervals, de,

a bracket 37 carry--v arms yare apertured at 49 (see Figs., 2 and 3). The apertures 49 form ways inwhich blocks 50 are mounted to slide. 1n these 'blocks are -journaledshafts 51 upon which are Amounted guide pulleys 52. 4These engage the conveyer 'belt 42 from above. A spiral spring 53 is placed in-each aperture 49, pressing against the upper wall ofthe aperture. and the top of the block 50 to It is apparent that the rods 33 and their brackets 37, the bars 43 and the shaft-s 39, form a continuous structure which `will be known as the conveyer frame. This is adjustable vertically by moving the rods 33 up and `down in their supports and/securing them-in the desired position by means of the I pins 34 in the corresponding holes of the series 35. This provides for the treatment of cans of different diameter.

Each forward bracket 37 (see Fig. 18) uis provided with a horizontal forwardly extending' arm 55 having at its extremity a bearing.- A ,transverse vshaft 56 is mounted in,the bearings of the two brackets. An

`arm 57 rigidly secured to this shaft is provided-with av follower 58 which engages a cam 59 lon the forward -shaft 39. A torsion spring- 60 encircles the shaft 56 and is secured thereon at one extremity by means of -a collar 61. The other extremity yof the spring is secured to the bracket 55. The shaft- 56 is above the trough 17 and extends across it near the forward extremity thereof vand spaced sufficiently from the trough to be out of the path vof the largest can to be treated.

Two fingers or stops 62 and 63 (see Figs. i

9 and 10) are secured tothe shaft 56 at a point over the path of the cans. These fingers are mounted in blocks 162 and 163 apertured to receive the `shaft and held by means of set screws 64 andmay be `adjusted to suit the operator.. The lingers `areL-s'l'iaped, in elevation the end of onel arm of the L being 'secured' to the. shaft in a radial position and the other arm depending. The lower extremityv of the depending arm of each finger is bent inward toward the other so that it extends in ahorizontal directiontransversely of the machine. The lingers are so placed in regard to their shaft 56 that they are separated byl an angle Vof 120o below. The depending arm of one L-shaped iinger'is'on each side ofthe shaft 56 and the two dependfollower 'is on the high point of the cam (see Figa-9,) this finger is raisedl and the rear iin- `ger63 extends' into thepath ofthe Scans.. If

the finger 63,engaging the forward can of a lmeberaisedb 'the' action o'f the cam, the

, front finger 62 escends in'to the path of the can's,` fengaging the next one of the line so as toer-'rest its advance. In this way, at each' complete rotationof the forward shaft 39, one can is released.. Therefore, the feed of the cans to the conveyer is timed so it is proportionate to thev speed of the conveyer belt and the brushes.

T wo cylindrical brushes 65 (see Figs. 2 and 6) are mounted on the frame of the ma-. chine with their axes parallelto the ways and on a flevel with the axes of the cansv thereon. vThese brushes are supplied with coating material androtated to' coat the end of the cans. Each brush 65 (see Fig. 6) is secured to a shaft 66 journaledin 'a bearing .member-67 mounted on a horizontal rod 68 which passes throughas'uitable aperture in a blockv l68and is adj ustablvy secured therein by means of a set screw 169. This block is aperturedto receive aiv'ertical rod 170 and, may be adjusted vertically relatively thereto. 4The block 168 is apertured to receive a pin 69 which engages anyone of a series of holes 70 in the ro'd- 170. A line of numerals 71 is placed on'each rod to indicate the -position of the brush. Aprons 7 2 in'closing the brushes from .the outside andv extending downwardly therefromto catch the coating material which drips .from the brushes are securedto vthe bearing members 67. These aprons terminateat their upper extremity in a straight'edg'ewhich is over the brushes and 'a trough 73. for each apron issecured there-q to, extending beyond the edge and depending therefrom. '.These, troughs areperforated at the bottom 74 .to allow liquid which is placed therein to drip on the brush below.

Each brush shaft is provided 4at its .rear exi' .7601i the brush shaft tremity with a pulley 75 secured thereon, v(see Figs. 3 and 4). lA bevel gear 76 is. mounted on the conveyer beit shaft 39 on each side of themachine -and each bevel gear 76 engages a companion bevel gear 77 on a -stud 78 secured to the bracket 37 4at right an= gles to the shaft 39. A pulley-..79 mounted on the stud 7,8 and secured `to the bevel 77 drives a belt which runs over the pulley and imparts rotation to the brush.

)Vhen theJ conveyeris adjusted to provide for the variation in diameter of the ldifterent size cans to be treated, it is apparent that,

`it must be moved substantially twice as far as the brush' is moved to meet the samel va- Jriation in size of the cans. `This is. forthe reason that the -variation of the diameters is against the belt-80. e l

the outer extremity of the stud 78 and held justment, the distance between the pulleys 79 carried by the conveyer frame and the' pulleys 75' carried by the brush frames is varied'.- To provide fory this variationconveniently, an' .automatic belt tightener is ..used. 'lhis is shown in detail in- Fig. 5

which is a vertical section -taken along'the laxis of the stud 78. The belt tightener con-V sists of a radial arm 81 having an elongated hub 82 journaled on the stud 78. At the extremity ofthe arm remote from the stud is an idler 83 journal-ed on the arm to bea'r A collar 84 mounted on in position by a pin 85 prevents'displa'cef ment of the hub82 longitudinally of the stud. A spiral torsion spring 86 encircles the huband is secured at one extremity to ,the collar and at the other extremity-to the arm 81. The tendency of the spring is to press the idler 83 against the belt and the desired pressure may be secured by .withdrawing t-he pin 85 from the stud and windving or unwinding the spring by rotating the collar. At the desired tension, the pin is replaced in its hole. l At the rear of the conveyer belt, with its axis in a plane above and parallel to the plane of inclinationofthe rear ways, is a. brush 8 6 (see Fig. 4), the function of which -is to distribute the' liquid coating over cylindrical can bodies. This brush which will hereinafter-be knownas the-body brush' is placed diagonally across the ways 5,. t', e., it

extends from a point over one side. of thev ways just in the rear ofthe conveyerv pulleys to a point over the other vside of the ways a considerable vdistance farther backV in the machine and shown as adjacent the rear end of theways. rThe body brush is secured toa suitable shaft 87 which is mounted at its forward end torotate in afbearing member 88. j Above-and at one-side of the ways, this bearing member is secured2 to the lowerend of a depending rod 89 which has a. sliding Y bearing in a block 90 and-is securedtherein This block isby means ofV a set screw 91. supported on the .shaft 89 between a bevel gear 76 and. one of the conveyer belt pulleys 40. The rear extremity of the shaft 87 is journaledina bearing 92 above and at the i uprights`99 secured to each vbed-rail 2. T he4 block 97 is secured to the rod 98 by means of set screws 100 and rotation of the rod in the brackets 99 is prevented by means of screws i 101. A pulley 102 is secured to theshaft- 87 in the rear of the brush. This pulley is engaged by a belt 103, guided by idlers 104fon theblocklO (see Fig..3).' This belt also engagesl the pulley'y 106 on. the shaft 39,

whereby rotation is communicated to thebody brush 86. It willfbe apparent from this description that the* forward end of the body brush may be adjusted vertically by moving the rod 89through the block 90, and thatA the rear end of the brush may be adjusted laterally by' moving the block 97 along the rod 98, and vertically bymoving 'the block 94 along the upright rod 95.

vIn theoperation of the machine, cans are Y placed in the -trough 17 (see Fig. 8).v The vice.

, inclination ofthis trough givesthem a tend-` ency to move to the rear into the machine i propelled by the force ofgravity. The cans are centered'in the trough-by'meansof' thel springs 19 (see Fig. 7 These springs press against the lhea'd's of the advancing vcans and guide them as they approach the spacing deiinger 62 is depressed and the `finger 63 raised (see Fig. 9); the cam follower 58 being on the lowportion of the cam 59. The first can of the line comesin contact withv the finger 62 and its advance isarrested. As the rotation ofthe cam continues in the direction of the arrow in Figs. 9-and 10, the vfollower is released and moves forward into the machine and another can moves forward against the depressed finger 62. Inthis way, at each complete revolution of the forward shaft 39, one can is fed into -themachine As each can is released by the finger 63, it passes down the'incline 26 of thetrough 17 on to the forward end 28 or incline ofthe ways 10. As

the can moves down the incline of the trough and the ways, vit gathers a considerable amount of momentum, and the spring 29 which in its normal position is deflected upward into the path of the cans is depressed.`

As the can reaches the` bottom of the depression 27, its downward momentum is checked by the ways and the reaction. of the spring 29, the forward portion of which is under the can in this position, throws the' latter upward against the conveyer belt 42 which drives it in rotation. 'lhe cylindrical surface of the can now engages the pad 14 and the can rolls forward on the pad by At thisistage of the operation, the

yirtue-'of the rotation imparted to v'it by the elt'.

of'the belt, com resses the mat or pad 14 and it yields su ciently to allow the edges of the can to-engage the upper surfaces of the rails 10, the upright portions 25- of which have their front ends just back of the depression,27. The belt is maintained in contact with the -upper element of ythe 'cylini drical surface of the .can by its tension and by the pressure due tothe yielding guide.

rollers 53. The cans are thus rotated by the belt' substantially without slip. They roll forward along the ways 10, z'. e.,to-the right, as seen in Fig. 3. During the passage of the cans`- along the horizontal portion of the ways, their en ds are brushed continually by v'the rotating brushes 65 to which the liquid' coating is fed from the perforated troughsv .74, as previously described. Spa-tt'ering and spraying ofthe liquid is prevented by -the aprons the liquid as are thrown upward vorcoii'tward from the brushes to the trough 172 which is `drained into a suitable receptacle"17 3. The` liquid which is thrown downward is re The pressure of the can onthe p ad, .due tothe weight of the can and-.the action.

2 which conduct such portions of tained by the pad and.' smeared on the cylin- Y drical bodies of the cans. It is important to note that the `conveyer belts, the brushes, the aprons and the ways are adjustable to receive cans' of any length or diameter within'the desired limits. As has been set lforth in connection with Fig. 2A the side rails v13 and th'e ways 10 may be ,adjustedlaterally' at 'the will `of the operator, providingfor cans of any length lwhich may be used. By reference to Fig. 6,

it is apparent that the brushes with their covers may likewise be adjusted laterally by sliding the rods 68 horizontally through the blocks 168 and securing them lin adjusted position by the set screws 169. To provide forl cans of diflerentdiameters, the conveyer` belts 42 `with their driving pulleys 40 and carrier pulleys 41 and the guide pulleys 47 and 53, with the convey-er frame they are mounted, may be adjusted vertically by sliding the rods 33 through lthe brackets 32 and placing the pins 34in the appropriate holes of the series 35; ,These holes are so placed as to accommodate cans of the sizes used in the trade. In order that cans of` different diameters may be properly treated by the end brushes 65, these brushes areI made adjustable vertically so the axes of the brushes may be kept in the plane of the can centers. This is dohe by sliding the blocks 168 along the upright rods 170. The blocks are secured'in adjusted position by inserting the pins 69 in the appropriate holes of the series 70 inithe upright rods. These holes are placed to correspond to the .different sizes of cans and are numbered for the convenience of the operator, as previously set upon which' forth. .By numbering the-holes and advising the operator as to the particular adjustvment to be had, ver-y little is left ltohis judgment. The functions andthe operation of the belty tightener havebeen reviously de scribed and further description thereof 1s 'thought to be unnecessary. As the can4 leaves the end brushes 6,5, it passes beneath the rear guide pulleys 47 ot' the conveyer belt and out of contact with the latter.

From the depression 27 to .this point 24 bein their -passage by the force of gravity.

As a can gathers speed on the incline, it

comes in contact with the cylindrical body brush 86 which serves to distribute over the can body the coating lliquid already applied thereto bythep'ads 14. In this connection it is important to note that the liquid for coating the can bodies is fed to the end brushes 65 only and enough of thisliquid to coat the cylindrical bodies'of the cans is thrown by the brushes 65 and becomes deposited on the pads during the operation of the machine, and somefef this liquid, after continuous operation of the machine, becomes distributed over the brush 86. As the can first comes in contact with the brush 86, a zone on the can body adjacent one end is engaged by the brush.` As previously described, the 'brushextend's to the rear and diagonally across the ways, so that as the can advances the zone of contact moves from one end of the can to'the other andthe .whole surface is thoroughly treated. The

adjustments of the brush. 86 and its drive have been previously described; further notice. thereof is unnecessary.

This machine, though described as for applying lacquer, may be used, and is used, for cleaning cans. In this case, stiff wire brushes may be substituted tor the bristle brushes shown and nolacquer used. As lthe is no't rubbed.l The contacting edges of the railsare so thin that they remove but very little of the. liquid, forming a fine line ove'r which the liquid closes before drying takes place. A stop 131 may be placed at the end of this trough to arrest the advance of the cans so that they may be removed by thel operator, or they may be delivered at this point to a suitable receptacle or .to another conyeyer. y
