Claims This invention relates to improvements in labeling machines and more particularly to improvements in labeling machines of the type designed to place labels about cylindrical cans and 5 the like as they roll through the. machine.
In the application of labels to cans, buckets and other containers having peripheral ears, lugs or projections, it has been difficult to embody in an automatic labeling machine, mechanism which would continuously feed the cans or containers to the stack of labels, so that the lugs or projections on the cans or containers would register with the apertures in the labels provided therefor.
An object of the present invention is to provide an improved labeling machine having mechanism adapted to automatically position cans or containers having lugs or projections so that when the cans roll onto the labels, the lugs 20 or projections on the cans will register with the apertures in the labels.
Another object of the invention is to provide an improved can registering mechanism for labeling machines, which is simple in construc- 25 tion, and reliable and exact in function under all conditions of service. I
The invention also comprises certain new and useful improvements in the construction, arrangement and combination of the several parts 30 of which it is composed, as will be hereinafter more fully described and claimed.

Referring to the drawings, the machine shown is similar in structure to previously patented 55 machines, the machine of United States Patent No. 1,995,306, granted March 26, 1935, being a good illustration of this type. The drawings illustrate a labeling machine of the type referred to adapted to the labeling of cans or containers having lugs or projections extending beyond the body, such as cans or buckets with lugs for bails or handles, or jugs and bottles with handles.
As shown in Fig. 1, the machine comprises a suitable supporting frame structure, indicated at Supported by the frame H, is a super structure, indicated at E2, and this super structure, and the parts carried thereby are adjustable, in the manner described in detail in the above referred to patent, so that-cans or containers of various sizes can be accommodated in the machine.
The cans or containers are fedto the machine by means of an inclined platform 55 which directs the cans towards a track consisting of pairs of spaced parallel bars it, ill, it and The tracks 16 and ii extend from the feed end of the machine downwardly towards the center of the machine, and the tracks l8 and i9 extend from the inner ends of the tracks H3 and H upwardly towards the discharge end of the machine.
The adjacent ends of the tracks it and ii and i8 and I9, respectively, are spaced apart, as shown in Fig. 1, so as to provide a gap in the track for a trip finger 226 of the label feeding mechanism described in detail in Patent No. 1,995,305.
Disposed above the track are guide bars-2o and 2! adapted to engage the ends of the cans or containers and prevent lateral displacement thereof as the cans move through the machine.
If so desired, the guide bars 25 and 2i may parallel the tracks.
Supported by the super structure 52, is a pair 40 of endless belts 22 which-are mounted on pairs of pulleys 23 and 2d, the pulleys 23 being driven from a suitable source of power, such as an electric motor 525 operatively connected thereto by gearing, as fully described in the above referred to patent.
. For engaging and properly spacing the flights of the belts 22, intermediate their ends, are pulleys 2t.
The upper flights of the belts 22 are engaged by wheels orrollers El, and the lower flights of said belts are engaged by spring pressed rollers 28.
The rollers 28 urge the lower flights of the belts 22 into contact with the cans or containers sheet of sponge rubber or the like. The pad 33 is formed. with a plurality of apertures 34, the purpose of which will be hereinafter described.
Adhesive is applied to the cans or containers as they pass downwardly over the tracks l6 and il towards the center of the machine, the adhesive applied to the cans or containers being adapted for engaging and lifting a label from a stack in the manner described in Patent No. 1,995,306. The adhesive is contained in a receptacle 35 disposed beneath the tracks it and l! and located at a convenient point intermediate the ends of the machine and in advance of the disposition of the stack of labels.
Adhesive is taken up from the container or receptacle 35 and applied to the cans or containers by means of a toothed member 36 operated by the driving mechanism of the machine in the manner described in the above referred to patent.
Means are also provided for applying a line of adhesive transversely of the labels so that after the main body of a label has been aflixed to a can or container the overlapped edges of the label will be sealed. This mechanism, which is shown in detail by Figs. 18, 19 and 20 of Patent No. 1,995,306, is located at the point where the tracks is and i9 meet the pad 3i, as indicated at 31, in Fig. 2. As shown in Fig. 3the labels which are aifixed to the cans or containers by the machine, comprise an elongated rectangular body fill having formed therein at spaced intervals a plurality of apertures 52.
In the instant casev (see Fig. 4), the cans or containers 13 have a pair of diametrically disposed bail lugs 4 formed thereon for bails or handles (not shown).
The apertures 22 are of a size to easily permit the lugs 64 or other projections extending beyond the body of the cans or containers to pass therethrough, and consequently said apertures are spaced apart a distance equal substantially to one half the circumference of the cans 413 so that when the cans are rolled over the stack of labels in the machine by the belts 22, the lugs M will register with the apertures 42,
For the purpose of positioning the cans or containers 2-3 so that the lugs M will register with the apertures 42 in the labels 4, an improved registering mechanism consisting of two members 35 and it, applied to the tracks l6 and H, respectively, is employed.
The members 45 and it are positioned on the track at a distance to the left, as viewed in Fig. 1, of the adhesive container 35, so that the cans or containers entering the machine from the feed platform l5, will be act'edupon by the registering mechanism prior to the application of the adhesive to the cans.
The track bars iii and H are spaced apart a suitable distance in order to support the cans or containers 43 in the" manner shown in Figs.
The tracks 46 and IT are respectively formed with elongated slots 41 and 48 which may be of any suitable length.
The side walls of. the slots ll and 58 are so formed as to provide inwardly projecting flanges Q9 and 50, respectively. These flanges are located in the bottom portion of the slots 47 and 48 and constitute ledges, the purpose of which will be hereinafter more fully described.
Suspended from the track i5 is a housing 5% which is U-shaped in cross section, as shown in Figs. 6, 9 and 1 0.
Disposed within the slot M, as shown in Fig. 10, is a roller 52. As viewed in side elevation, (Fig. 4) the upper portion of the roller is located in a plane above the upper surface of the'track it. The roller 52 is free to rotate on a pin 53 carried by the housing 5!.
Also rotatably mounted in the housing on a pin 54, is a toothed wheel 55 which is disposed in spaced relation with respect to the roller 52, as shown in Figs. 4 and '7.
The periphery of the wheel 55 isformed with small teeth 56 adapted to be engaged by a pair of spring pressed pawls 5'! and 53 pivotally mounted in the housing 5i.
The upper portion of the toothed wheel 55 is located in a plane above the upper surface of the track it.
The upper surface of the housing 55 is planed smooth to snugly engage the abutting surface of the track it.
In order to clamp the housing 5i to the track it in such a manner that the housing can be moved lengthwise of the track so as to adjust the position thereof on the track for different sizes of cans of containers, suitable clamping means are provided.
At each end of the housing 58 are extensions 59 and 60, the extension 59 being formed at one end of the housing and the extension Bil being at the opposite end of said housing, as shown in Fig. 7.
The extension 59 is formed with a vertical bore iii adapted to receive a depending threaded stem 62 of a plate 63 mounted in the track 16 above the flanges 49.
The lower surface of the plate 63 rests on the upper surface of the flanges 49 and the upper surface of said plate is inclined, as indicated at M, Fig. 7.
The plate 53 extends from the front end of the housing 5i rearwardly towards the roller 52, the rear end of said plate terminating adjacent to the periphery of said roller.
The downwardly projecting threaded stem. 62 is engaged by an internally threaded clamping memberfit having a handle 6% adapted to be manually operated.
The extension 69 is formed with a vertical bore 67 adapted to receive a depending threaded stem 68 of a plate 69 mounted in the track it above the flanges 49.
The plate 69 has its lower surface resting on.
the upper surface of the flanges 49 and an upper inclined surface it.
As shown in Fig. '7 the plate 68 extends from the rear end of the housing 5!, forwardly towards the toothed wheel 55, the front end portion of said plate terminating adjacent to the periphery ofsaid wheel.
The threaded stem 68 is engaged by an internally threaded clamping member H having an operating handle 72. 1
As shown in Figs. 5, 6 and'8, the housing 5| is formed with a lateral extension 13 having an opening l' l formed vertically therein.
Mounted in the opening M is the depending portion 75 of a. member 76 which is adapted to be engaged by one of the bail lugs 44 on the cans or containers in the manner to be hereinafter more fully described.
The opening i i is otherwise closed by a plate ll which may be L-shaped in form, as shown in Fig. 6, said plate being detachably secured to the extension '53 by screws as shown in Fig. 5.
The bottom portion of the plate ll is formed with an opening '58 through which projects a threaded pin iii.
The pin '59 has threaded engagement with the depending portion is of the stop member 76.
Encircling the pin "E9 and bearing at one end against the plate ll and at the other end against the member '55 is a compression. coil spring 80. The tension of the spring 63 is adjusted by a nut @l mounted on the lower extremity of the threaded pin '59 and bearing against the under side of the plate 77.
Suspended from the track I! is a housing 86 of the regitsering mechanism 46. This housing is similar in construction to the housing heretofore described, with the exception that the lat eral extension 73 and the stop member '36 carried thereby are omitted from the housing 8%.
Mounted within the housing 86 is a roller 87, a toothed wheel 88, a front plate 89, and a rear plate 90, all similar in construction to the roller 52, toothed wheel 55 and plates 63 and G9, respectively, heretofore described.
As shown in Figs. 5 and 6 the registering mechanism i s is clamped to the track H in a manner similar to that above described in detail, by means of clamping members 9! and The registering mechanisms 35 and iii are positioned on the tracks iii and El, respectively, so that the rollers 52 and 81, and the toothed wheels 55 and 88 are alined, as shown in Fig. 5.
In operation, the cans or containers 43 are rolled through the machine by the belts 22. When a can or container reaches the registering mechansm it is carried off the tracks It and il by the plates 63 and 89 and over the. rollers 52 and 8?. The can then comes into contact with the toothed wheels 55 and 38 and also with the rollers 52 and Bi, and assumes the position indicated by full lines in Fig. 4.
In this position the bail lugs 44 may be disposed approximately in the position indicated by dotted lines, Fig. 4.
With a can thus resting against the rollers 52 and Bi and the toothed wheels 55 and 88, respectively, the can will be raised above the tracks 16 and ii. Through the action of the belts 22, which are moving in the direction of the arrow, Fig. i, the can will now be turned in the direction of the arrow B, the toothed wheels 55 and 88 rotating in the direction of the arrow C until one of the lugs 44 comes into contact with the stop member '16.
When 2. lug of the can engages the stop member 16, the peripheral movement of the can and the toothed wheels 55 and 88 is stopped momentarily. The spring pressed pawls ill and 58 prevent movement of the toothed wheels in the direction opposite to that shown by the arrow C in Fig. 4, and consquently, due to the action of the belts 22 the can is now rolled forwardly over the top of the toothed wheels 55 and B8 and onto the plates 65; and 9! and thence ontothe tracks 16 and Il, respectively.
Due to the fact that a lug M of the can has been moved into engagement with the stop member 76, the can will roll forwardly from the registering mechanism with the lugs thereof in correct position to pass into the apertures in a label, so that in the application of a label around a can the lugs will register properly with the openings provided therefor in the labels.
When a can has stopped its peripheral movement with one of its lugs against the stop 16 and is carried forwardly over the toothed wheels and 88 in the manner heretofore described, and attains the vertical center directly over the center of the axis of the toothed wheels, as indicated by the broken lines D, Fig. l, there is a tendency for the can to turn, .the toothed wheels in the direction opposite to the arrow C and skid downwardly over the toothed wheels onto the tracks.
In order to prevent any slipping movement of the cans or any reverse movements of the toothed wheels, the periphery of said toothed wheels are formed with the notches or teeth 56. These teeth have two functions, one function being to prevent slipping of the cans as they roll over the wheels, and the other function being to receive the pawls 5'1 and 523 and thereby provide means for preventing backward rotation of the wheels.
Therefore, if the wheels were formed with smooth peripheral surfaces and no locking or ratchet means used, there would not beany means for controlling the rotation of the wheels,
and consequently the cans would skid or slip while being rolled over the wheels by the belts 22, with result the accurate or positive registration of the lugs of the cans with the apertures in the labels could not be had.
After labels have been attached to the cans in the manner described in Patent No. 1,995,306, the cans will roll over the belt 32, the lugs M of the cans entering the apertures 3 in the surface 33 of the belt. From the belt the cans will pass onto the discharge platform 39 and be directed thereby away from the machine.
From the foregoing description, it will be noted that by the present invention the members 45- and it are mounted on the tracks l6 and H, respectively, in such a manner that the tracks can be moved toward and away from each other when the machine is being adjusted for the purpose of accommodating cans or containers having dimensions of other sizes than the dimensions of the cans for which the machine may be set, without the necessity of readjusting the relative positions of said members in any manner other than the setting of the members lengthwise of the tracks, as has been heretofore described. This is due to the fact that each registering member is individually mounted on each track without any connecting elements therebetween.
Having thus described my invention, what I claim is:
1. In a labeling machine for affixing a label to a can having bail lugs and the like projecting from the body thereof, a pair of spaced tracks for supporting the can, means for rolling the can along the track, label supporting, feeding, and pasting means, adhesive applying means, an elongated slot formed in each track, a pair'of spaced Wheels suspended from each track in front of the adhesive applying means and extending through the slot in the track for engaging and supporting the can above the track,
