Patented June 21, 1932 UNITED STATES PATENT! OFFICE CHARLES H. W'ILD, OF BALTIMORE, MARYLAND, ASSIGNOR TO BURT MACHINE COM PANY, INCORPORATED, OF BALTIMORE, MARYLAND, A CORPORATION OF MARY- LAND CAN LABELING MACHINE Application filed. October 5, 1929.

In accordance with the present existing practice in the labeling of cans and similarly shaped packages, the cans or packages are rolled by a belt or other propelling means along suitable ways which overlie the label pack. The cans or packages are spotted with adhesive before they reach the label pack and as each can passes over the pack, it picks up a corresponding label which is wound about the can as it rolls forward through the machine. To complete the labeling operation each label is coated as to its lap end or rear end, view of the rolling action described, with adhesive supplied from a second paste receptacle known as the Formerly, a thick adhesive was used and the paste pot was open at the top to provide for the introduction of the adhesive in solid form. The open paste pot admitted more or less dirtwhich, being transferred to the labels, disfigured the finished packages, and, in addition to this, considerable difficulty was involved in the attempt to attain uniformdistribution of the adhesive on the respective labels so that comparatively close supervision of the pasting mechanism with corresponding expense in the operation of the machines was involved in order to supply the adhesive in uniform charges to the respective labels in turn.

The present invention relates to an improved lap end pasting mechanism in which the feed is controlled by the cans as they pass and in which the rate of feed may be adjustable so that any desired rate of distribution can be obtained in strict proportion to the number of cans fed. Also the paste pot is preferably closed, the difficulty incident to the presence of dirt in the paste is completely overcome.

In the accompanying drawings Ihave illustrated a paste feeding mechanism embodyin the improvements of my invention, together with so much of a can labeling ma- Serial No. 397,602.

Figure 13 is a plan view corresponding to Figure 2, showing the modified form of noz zle, the adjacent portion of the machine being shown in dotted lines for convenience of illustration.

Referring to the drawings by numerals, each of which is used to indicate the same or similar parts in the different figures, the construction shown, particularly in Figure 1, comprises the frame of the machine represented by side rails 1, between which are provided suitable means forming ways 2 for sup porting the cans. On each side of the ways are suitable can guides or rails 3, the cans being propelled through the machine by any suitable means as a belt 4, held in contact with the cans by means of rollers, 5 controlled by means of suitable. roller guides 6, mounted on supports 7, all in accordance with the usual practice. Beneath the ways in registration I with a suitable opening provided therein for this purpose is a label tabIeS-ada-Ptedto carry and support a pack of suitable labels 9.

The pasting mechanism which is the subject of the'invention consists of a standpipe in the form of an upright tube 10, Figures 1 and 3, open at the top at 11 and mounted on the frame of the machine at theside adjacent and near the rear end of the label table as shown. In the form of the invention illustrated, this standpipe is provided with a depending lug 12 carrying a boss 14, which is apertured at 15 to receive a stud 16,,secured to the frame in any suitable manner. As shown, the boss 14 is bored and tapped to receive a set screw 17 by means of which. the standpipe is secured in position on the stud 16, the parts also being connected by a key 18 which prevents the rotation of the standpipe about the stud and looks it in upright position. The illustration also includes a paste pot 20 at the top of the standpipe. This paste pot is provided with a tubular outlet 21,.integral with its bottom wall as hereinafter described. This tubular outlet 21 fits inside the open upper end. 11 of the standpipe whereby the paste, pot is connected to and supported on 4 the standpipe.

The standpipe 10 is shown as formed and provided with a bulkhead 22,, Figure 3, near the bottom of the upright portion 25,v which li ulklieadv contains a port 24 leading clownwardly from the upright portion 25 to the discharge portion 26. This port 24 is provided at its upper end' with an upwardly disposed valve seat 27, which cooperates with a valve 28 shown as mounted toslide. and constructed with, a depending plug; 23 which fits in the port 24, displacing its contents. Valve 28-23 is referred to as a displacement valve.

In the form of the invention shown the discharge portion 26 at the lower end of the standpipe terminates in a journal bearing portion 30, which is transverse to the direction of feed of the'cans being disposed. inwardly toward the center of the machine, i. e., to the right as, the machine is seen from the feed end, the paste pot being in accordance with the construction illustrated on the left side of the machine as thus viewed. This journal bearing and tubular member 30 contains a hollow shank or journal 31, which rocks therein and carries the paste nozzle or distributor 32 with which it is integral. This nozzle will be more fully described.

Referring now to the standpipe valve 28, see Figure 3, in the form of the invention shown, this valve is supported on a stem or shank 34, mounted to slide in vertical guides 35, suit-ably secured within the standpipe and the stem is further provided with spaced abutments or shoulders 36, engaged by a fork or'other suitable means, 37, carried by a valve actuating lever arm 38, mounted on a shaft 39 which rocks in suitable bearings 40 shown as mounted on the standpipe 10. This shaft 39: extending transversel through a passage 41, which runs rearwarc ly from the standpipe 10 just above the valve seat 24, and terminates in a rearwardly disposed opening 42, closed by a screw plug 43. The valve actuating lever arm 38 is located in said passage 41, the fork 37 projecting forwardly therefrom, i. e., into engagement with the valve stem 34. The shaft 39 carries, in addition to the arm- 38, which operates the valve 37, a rearwardly projecting operating arm 44. This arm is engaged from above by an adj usting screw 45, having a head 46 with suitable gripping means and a lock washer or collar 47 suitably keyed to the screw shaft, but adapted to slide longitudinally thereof.

This lock washer 47 is in the form of the invention shown pressed downwardly by a coil spring 48 against a threaded boss or nut 49 through which the screw is threaded. The upper edge of this boss is provided with a positioning notch 50 engaged by a positioning tooth. 51 on said washer 47, or the adjusting screw may be positioned in any suitable manner. The boss or nut 49 is in turn carried by an arm 52 secuifed to or projecting from the carrier arm '54 of a can tread or feeler 53, which can tread or feeler extends across the path of the cans immediately adjacent the paste nozzle 32, being shown slightly to the rear thereof. The treadle or feeler arms 54, one at each side of the machine, are pivotally connected to the machine frame or to a suitable bracket thereonat 55. The treadle or feeler is held normally raised and the valve 28 is held normally closed by a coil tension spring 56 connected at one end to a suitable stationary point 57 on the machine frame and at the other end to an upwardly projecting arm 58. secured to the valve operating arm shaft 39.

It must be apparent that the standpipe valve 28- being normally closed by the spring 5.6,it is opened or the width of its opening is temporarily increased each time a can passes through the machine depressing the can treadle or feeler 53. It will also be understood that passage 41 is provided for the accommodation of the valve lever 38, and that the plug opening 4 213 at the end of said passage provides for the removal and reinsertion of said lever, the shaft 39 being removed and inserted at right angles thereto.

In accordance with the usual practice, the main supply of paste which is thinner than that employed in accordance with the previous practice, is inserted in the reservoir 20, which is provided with a tightly fittingcover 60, see Figure L This paste pot also has a hand operated valve 61, having a seat 62 at the upper end of the tubular outlet 21, which valve has a substantially vertical traverse, being provided with an upwardly extending stem 63, and having a handle 64 at its upper end. The stem 63 is mounted to slide in vertical guides 65, supported in anysuitable manner in the paste pot. This valve provides for the closing of the paste pot outlet at any suitable time.

The valve 61 also includes a depending plug 60' which fits in the port 62 below the seat 62 displacing downwardly the contents of the port. In this way the plug 60 and port 62' act as a pump to fill nozzle 32 and the passages leading thereto when the valve 61 and plug are moved up and down, which operation is performed manuallyon starting after said nozzle and passages have been emptied as for cleaning.

The construction, operation and manner of mounting the nozzle 32 are also of interest. The nozzle 32 in the preferred form com prises a supply conduit 68 and a delivery or distribution conduit 69. Both of these conduits extend transversely of the can feed. They are, therefore, parallel to each other and are preferably formed of a single piece of metal, as best illustrated in Figure 6. The supply and delivery passages 70 and 71,

respectively, being preferably of oval cross section or otherwise elongated transversely to the length and in the direction of the can feed. These passages are connected at frequent intervals throughout the length of the delivery passage 71, by short transverse passages 7 2. The delivery conduit 69 is shorter than the supply conduit 68 and is preferably provided with a delivery slot 73 extending the entire length of its bottom wall, as best illustrated in the bottom plan, Figure 9, and the section Figure 6.

The delivery of the paste through the slot is further facilitated by transverse grooves 7 4 in the bottom surface of the delivery conduit 69. The delivery of the paste from the nozzle and particularly the length of the line over which the paste is delivered, i. e., the length of the opening of the delivery slot 73 is controlled by stops or plugs 75, see Figures 9, 10 and 11, which are inserted in the ends of the passage 71, the same being left open for this purpose. The depth or extent to which these plugs are inserted from either or' both ends controls the length of the delivery slot opening. The plugs 75 in the form of the invention shown are mounted on wire.

ribs 7 5 which fit in corresponding slots 73 to close the same.

The nozzle member 32 has been described as having a hollow j ournal31 through which the paste is admitted from the paste pot and standpipe 10 via the tubular journal bearing 30 at the bottom of'the standpipe 10. In the form of the invention illustrated in Figures 1 to 11,- this journal 31 is formed on the endof the supply conduit 70, adjacent the paste pot and the other end'ofthe supply conduit is provided with a stud in alignment with the journal 31-, which. stud 80 fits in a suitable bearing 81 on the machine frame supported by a bracket 82, provided for this purpose and secured to the frame.

By virtue of the structure thus described, the supply nozzle 32 is mounted to rock on the bearings 3031, 8081 about the axis of the supply conduit 68, permitting the delivery conduit 69- to swing up and down upon said axis.

Referring now to Figures 6 and 7, it will be noted that there is a leaf springer plate spring 83,011 each side of the machine secured to the frame extending forwardly and normally inclined downwardly so that its forward end 84 bears against the top of the delivery conduit 69, pressing the same into close contact with the lap end 85 of the top label 86 of the pack 9, said top label being shown in Figure 6 as drawn upwardly as to its forward portion 87, the extreme end of which not illustrated in this figure has been caused to adhere to the can 88 which is leaving the label pack, having passed over the same.

Figure 13 shows a modified form of nozzle. In some instances Where the adhesive used has been slightly too thick or for some reasons not fully understood, some difiiculty has been encountered due to the partial failure of the supply of paste at the end of the nozzle remote from the paste pot. The modified form referred to is provide with means tending to overcome this difiiculty. The illustration, Figure 12, includes a section through the lower part of the standpipe 100, the same being slightly modified as compared to the corresponding element 10 in Figure 8, providing an outlet at 101, leading to the secondary sup ply tube 102, which crosses the machine at right angles to the can feed and is connected to the supply conduit 104 of the nozzle 103 at the end of the same opposite to the paste .pot, the position of which is indicated by the standpipe 100, it being understood that the paste pot would; overlie the stand. The secondary supply pipe .,102 is turned backwardly uponvitself at the end re-.

pipe.

scribed form, being-provided at the corre-.

sponding axial end with a hollow journal 108 which fits androtates in a journal bearing 109 formed on the standpipe 100. The nozzle 103includes in addition to the supply conduit 104, a delivery conduit 110, the conduits 104 and 109 being related as in the construction previously described. 1

In the operation of the machine equipped with the paste supplying means of the invention, the cans are fed by means of the belt 4 or other suitable propelling means along the ways 2, and the labels 9 are presented by means of the table 8, all in accordance with the established practice. It being assumed that the stand-pipe 10, the nozzle and the passages leading thereto from the standpipe have been cleaned out and the bottom outlet of the paste pot closed for the overnight period of unemployment or the like and the pastepot 20 being assumed to be full or containing sufficient adhesive, the valve 61 with its displacement plug '60 is reciprocated slowly'by manual engagement of the handle 64. This operation serves to push downwardly through the port 62 sufficient paste to fill the nozzle and passages. The valve 61, including plug is then raised and set screw 64 is tightened, the collar 64 having been slid down into contact with the upper guide 65 holding the valve in open position. The paste is thus permitted to continue to fiow downwardly into the standpipe 10. It being understood that the valve 28 at the bottom of the standpipe is normally closed, this valve is held open in any suitable manner to permit the discharge end 26 of-the standpipe and also the nozzle 32 comprising the delivery conduit 68 and the supply conduit 69 to become completely filled with the adhesive material. lVhen'this has been done, the valve 28 is permitted to close in response to the tension of the spring 56 acting on the upwardly disposed arm 58 of the shaft 39. v

The passage of the cans through the machine and over the label table brings them successively in contact with the top of the feeler 53. This feeler is narrow enough to fit'in the tapered space between the cans even if they are in contact soit requires no spacing of the cans and does not in any way affect or limit the speed of the machine,a high speed with slight spacing of the cans being almost requisite underthe present practice. In the form shown the feeleris located just beyond the label table, see Figure 7, in the direction of can feed, and is mounted on the arms 54 pivoted at each side of the machine, one of which arms carries the bracket or arm 52, see Figure l, on which a threaded head or nut 49 is formed. This nut supports and receives the adjustable pressure screw 45 by which the action of the feeler is communicated to the valve 28 opening the same or increasing the opening of the same as each canpasses, it being understood that the screw 45 bears on the rearwardly extending arm 44 secured to the shaft 39, which carries the forwardly extending valve operating arm 38, and spring arm 58 engaged by spring 56 to close the valve. As the valve is thus closed after each such upward movement, a quantity of adhesive corresponding to the said upward movement is pushed downwardly toward the nozzle, by the displacement action of the plug 23 in port 24. It will thus be apparent that there is a feeding impulse for each can that passes along the ways and over the label table which feeding impulse results in a corresponding exudence of adhesive from the nozzle opening or slot 73.

In this connection, it will be apparent that as different labels of different widths are supplied to the machine, the width or rather the length of ti e feeding slot 73 or the effective portion thereof and the position thereof laterally of the machine, may be adjusted, varied and determined by the positions of the respective plugs 75,,which are accordingly inserted or withdrawn. The paste is thus exuded from the nozzle as each can strikes the feeler 53 and the feeding impulse is transmitted from the paste pot to the outlets 73 with sufficient speed to cause the contact of each can with the feeler to result in the delivery and application of a corresponding charge of adhesive to the lap end of the label which is being taken up by thecan. This relation of the parts will be apparent from Figure 6, which shows the can 88 picking up a label 86, the lap end of which is still in position on the pack extending well back of the nozzel slot 74, the can being at the same time in contact with the feeler 53. It is also apparent that the nozzle being pivotally mounted as shown, the spring 83 serves to incline the nozzle member downwardly and forwardly keeping the delivery conduit 69 and the feed slot 73 thereof in contact with the top label. This has the effect of backing up and accumulating a quantity of adhesive 74. rearwardly of the slot 78. This assists in spreading the adhesive and bringing it; in close Contact with the end of the label adja cent the lap end thereof. i

As the can 88 proceeds through the machine, the paste coated lap end 85 of the label is brought in contact with the can by the winding of the label about the can as the latter advances, and the can having completed the picking up operation and passed over the feeler 53, comes next in contact with the pressing pad 90 by which the label is smoothed and pressed against the surface of the can, the contact'of the label with the can being thus perfected.

The operationin the modified form of Figure 13 is in no wise different from that of the form described except that the supply conduit 104 of the nozzle is fed from both ends toward the center instead-of from one end of the nozzle as in the construction. just described, i. e., fromthe standpipe 100, the paste flows to the adjacent end of the supply conduit 104 by way of the hollow journal 108 and the journal bearing 109, which'is connected directly to the inside of the standpipe 100 and theliquid adhesive passes to the other end of the supply conduit 104 by way of the secondary supply tube 102, which is connected at 101 to the standpipe 100 and at the other end at 105 to the supply conduit, the end 105 serving as a hollow journal which occupies the journal bearings 107, which is continuous with and connected to the inside of the supply conduit 104.

In addition to the other improvements and improved results obtained, the new construction makes it feasible to feed a thin liquid adhesive instead of the semi-solid variety previously used and to deliver the same to the labels in direct proportion to and in accordance with the number ofcans fed, the feeding impulse being transmitted through the entire line, i. e., from the paste pot to the outlet of the paste nozzle. According to the preferred arrangement, as each can passes from the label pack, the feeding impulse of each can serves to apply the necessary amount of paste to the lap end of the label which is being I taken up by that can.

Other important improvements and improved results have been fully discussed in the specification. j

I have thus described specifically and in detail a can labeling machine embodying the features of my invention in the preferred form in order that the nature, manner of operation and construction and using the same may be fully understood, however, the terms herein are used descriptively rather than in a limiting sense and the scope of the invention is defined in the claims.
