chine susceptible of various uses and adaptatlon's.

In more particular detail, the invention from a paste receptacle beyond the end of the label receptacle, the operative end. of the endless carrier normally occupying aposition above the supply of labels and spaced termittently moved so as to contact with the uppermost label and move the same from the pile of labels by mechanism engaged by a passing can and also adapted to be inter- --engaged by the passing can, so as to present a new pasted area to successive cans. vThe invention also embraces a novel construction of endless paste carrier and associated feed therefor, thereby effectively overcoming the usual stretching and twisting of the belt in operation and insuring a uniform feed from side to side of the belt.

Further, the invention includes novel supassociated lap end-pasting mechanism carried thereby permitting of quick and accurate-adjustment and assembly and detachability of the partsyand regulating to a the lap end of the label.

-' In ractice it has been found that the supor label receptacle will usually sag, thereby outline, and it has therefore been found ditfi- -cultto thoroughly and evenly coat the lap endaof the label from side to side, and to overcome these difficulties it is contemplated ing member for the'operative part of the paste carrying member-which engages the label, whereby the paste 'carrying'member assumesa position more accurately conforming-to the usual curved outline of of labels. Other and furtherimprovements. inthe construction and novel details in the'construction and arrangement of parts will be :tion, to follow, which for a comprehensive understanding of the invention should be considered in connection with the accompanying'drawings forming a part hereof and nicety, the extent ofthe coating of paste toply 'labels'when in position on the support more particularly referred to in the descrip' r wherein isdisclosed for the purpose of illus-- includes an endless paste carrier supported.

presenting a substantially curved surface in by the inventor to provide a novel support-5 the supply.

tration convenient and satisfactory embodiments thereof.

In the drawings: Figure 1 is a side eleva-' Fig. 5 is a section on substantially the line' 5-5 of Fig. 3 looking in the direction of the arrows, and, Fig. 6 is a front elevation (enlarged) of the la end paste receptacle and associated mec ianism, parts being shown in section. Fig. 7 is a side elevation of a modified and preferred form of trip mechanism for moving the paste applying member lengthwise, Fig. 8 is a top plan view of. the same, and, Fig. 9 is an end elevation of the paste pot showing an adjustable bracket which constitutes a stop for limiting the vertical movement of the paste applying member, the said stop being ada ted to be used in connection with a modi ed form of apparatus illustrated in the two preceding views.

With more particular reference to the drawings wherein like reference numerals refer to corresponding parts throughout the several views, 1 designates diagrammatically, the framework of the machine. Suitably supported on the frame adjacent the forward end thereof is a paste receptacle 2 having therein a paste applying roll 3 adapted to be driven by any suitable means and so positioned in the receptacle that the periphery extends above the top thereof and in the path of a passing can so as-to place upon the periphery of the can a daub of paste. It is obvious that any of the approved pick up pasting appliances may be used, as also means for moving the cans along the runway, such means as disclosed in the drawings being shown merely for the purpose of illustration and not constituting any part of the present invention.

The can runway is indicated by the numeral 4i, and the means for feeding the cans longitudinally of the machine takes the form of an endless belt 5, cut away in the drawings, and driven in any suitable manner.

6 is a label receptacle adapted to support a supply of labels which latter may be automatically fed upwardly in the receptacle as by the usual spring pressed follower not shown. The forward upper end of the label receptacle is cut away, as at 7, thereby exposing the forward end of the label in order that the same may be contacted by the pasted portion of the can and picked up by the can in the rotary movement of the latter. The labels assume an inclined position in the receptacle, and suitably supported adjacent the top of the receptacle and toward the rear thereof is a curling bar 8 of any desired'construction and operating in the usual manner to curl thelabel whereby it more ieadily conforms to the peripher of the can and is wound thereabout in tie movement of the latter. The rear end of the label receptacle is cut away, at 9, whereby to expose the rear or lap ends ofv the labels in order that the same maybe sup lied with a coating of paste previous to Eeing'withdrawn from thereceptacle by the moving can.

The pasting mechanism forthe lap end of the labels which constitutes the foremost feature of the present invention will now be described. The paste receptacle proper 10, may be of any approved outline, the same being supported in a manner to be hereinafter referred to, and adapted to receive a rotatable paste pick up roll 11, the periphery of the roll projecting above the upper end of the receptacle and extending substantially from side to side thereof. The paste receptacle is adapted to be positioned to the rear of the label receptacle and'the roll 11 moves upon an axis extending transversely of the machine, the shaft 11 of the roll extending without the side of the receptacle and adapted to be driven in any suitable manner. The shaft 11 is supported in the receptacle and prevented from endwise movement as by collars 11 and 11 arranged to the outside of the receptacle and held as by bolts in any desired manner. The roll 11 is suitably keyed to the shaft 11 whereby upon removing the collar 11 the shaft may be removed from the o posite side of the receptacle and the rol er 11 taken out of the top of the receptacle and cleansed as desired. Upon one end of the shaft 11 and to the outside of the receptacle is suitably mounted a gear wheel 12, adapted to mesh with a pinion 13 supported at one end on a suitable shaft 14 supported in upwardly projecting ears or bracket members 15 at the sides of the receptacle. This shaft 14: supports a suitable roller 16 keyed thereto, whereby upon removing the securing collar 17, the shaft may be removed from the roller and from the receptacle.

A swinging support conveniently U-shaped in outline is supported upon the shaft 14 and preferably comprises oppositely disposed arms 17 "having a collar 17 at one end, one of which is adapted to loosely it over the shaft 1 1 between the bracket 15 and a suitable collar 15 on the pinion 1,3, and the collar of the other arm being adapted to loosely fit over the opposite end of the shaft 14.- between the bracket 15 and securing collar 17. Adjacent the free end of the arms 17 are apertured blocks 18 adapted to receive the arms 19 of a substantially U-shaped support 20. The U-shaped support is adapted for longitudinal adjustment relative to the arms 17 and is secured in adjusted position,

being adapted to be engaged by suitable chains 22 secured Ito opposite sides of .an endless: aste-carryingbelt .24, the :said belt being a apted toengage over the roller 16 at one end and over :the'connecting arm of the U-shaped member 20 atanbpposite-end;

movement lbeing imparted to the belt by the toothed wheels 2211f Ithe roller 16, engaging the chains, :as stated.

Projectin downwardly from 'the :opposite arms L aresuitahle spr' members .25 secured "to the :arms in :any desired manner, and restingat their lower ends on the up er edge of the receptacle 10. When the la 1 receptacle is in :position the forward end of the endless paste carrying member '24 pro jects over the upper surface of the labels at the rear end thereof, and the function of the spring members 25 "is to normally space said forward end of :the endless carrier outof contact with the stack of 'labels. This feature constitutes an important element in the improved construction, since as is customary, should the endless aste carrier remain in contact with the stac of labels, not only the uppermost iabel will absorb the paste, but the moisture will leak through to the under labels and thereby cause the latter to become injured, as by wrinkling.

It is contemplated to intermittently and positively move the operative or forward end of the endless paste belt toward and away from the supply of labels through its carrying frame, while maintaining the belt in its normal stretched or taut condition, as distinguished from flexing the belt so as to contact the same with the labels. In the upward movement of the carryin frame, the uppermost label, the lap end 0 which having received a coating of paste from the endless carrier, will stick to the carrier and be raised out of contact with the stack of labels thereby providing against the supply of labels being effected by the moisture of the paste on the topmost label. Novel means is provided for so moving the carrier frame of the paste member, and while one of said means may be employed, the best results are accomplished by two, one to each side of the machine to engage each side of the carrying frame and adapted to act simultaneously. Since the means at either side of the runway are substantially duplicates, a description of one will suflice for the other.

26 is an elongated arm loosely supported upon a pivotal bearing 27, which latter is threaded to the side of the label receptacle 6. Threaded to the outer end of the bearing 27 is an adjusting nut 28, while sleeved upon the bearing intermediate the arm 27 and nut 28 is a spiral spring 29 connected atone end to the arm or a part carried thereby and at its opposite end to the nut 28. Secured to the arm is an elongated, preferably flat plate 30 of .a width to overlie the runway 4 and when moved to lowered position to lie flatil upon the said runway and offer substantia 29 is adapted 'to normally hold the plate 30 in an :upper inclined position, whereby it maybe engaged by a passing can and lowered into the said position flat against the runway. .The tension of the spring 29 may be regulated as desired, through the medium of the adjusting nut 28. Depending from the lower surface of the plate 30 to the outside of the runway, is a leaf spring 31, secured at one end as by bolts 32 to said plate and having a curved opposite end adapted inthe lowering movement of the arm 26 with the plate 30 to yieldably engage a contact plate 33 on the upper surface of the U-shaped arm 20 and secured to the block 18. As the spring arms 31 engage the saidplates 33, there being one to each side of the runway and for each arm 31, the endless y no obstruction thereabove. The spring paste carrying member is lowered into yieldengagement therewith, the said springs 31 will be automatically raised by the springs 29 so as to be in position to be engaged by a succeeding can. At the same time the sprin 25 will raise the operative end of the endless paste carrier upward and with it the lap end of the uppermost label which sticks thereto thereby being spaced from the supply of labels, the upward movement of the endless paste belt carrying frame being limited as by a bracket arm or arms 34 projecting upwardly from the paste receptacle 10 and adapted to overlie the side arms of the support for said paste carrier.

The U-shaped arm 20 which constitutes the Support for the operative end of the endless carrier may be adjusted whereby to adapt itself to the carrier and take up any play therein, and a convenient formation for the forward end of the member 20 is a curve, as illustrated more particularly and somewhat exaggerated, in Fig. 6. This particular construction of support for the carrier is of especial advantage since it allows the endless paste carrier to conform when in operative position to the general outline of the labels, it being noted in this respect that the supply of labels, in practice, usually sags. While various forms of constructions may be provided for o contacting the operative end of the paste carrying member with the labels from side to side of the latter, and while various modifications are within the spirit of the invention, the form of construction illus trated has been found very practice.

satisfactory in When the endless paste carrier member is in position on the receptacle 10, it will be observed that the lower portion thereof engages over the roller 11 whereby to receive a coating of paste from the said roller 11, which latter .is operated preferably intermittently, by the mechanism about to be described. Means may be employed to scrape the paste from the roller 11 and to thereby regulate the quantity of paste taken up by the same, the said means preferably including a scraper member 35 secured to the forward end of the receptacle 10 and having side flanges 35 to engage over the sides of the roll and carrying an elongatedmember 36 laterally adjustable, as by a screw and slot connection 37, the said member 36 being adapted to engage the paste on the body of the roll 11, and this engagement may be regulated by fastening the screws and adjusting the member 36, to thereby regulate the quantity of paste taken up by the roll.

The means for intermittently actuating the endless belt or paste carrying member is preferably controlled by the movement of the can along the runway and is preferably made up as follows. Secured to the gear wheel 12, in any desired manner, is a suitable ratchet wheel 38, and loosely sleeved upon the shaft 11 for rocking movement is a sleeve 39 at the lower end of a rocking arm 40 offset at its upper end, as at 41, and having a transversely extending plate 42 secured to the upper end of said offset portion 41. The plate 42 is substantially flat and is adapted in the rocking movement of the arm 40 to occupy a position when lowered flat against the runway 4, and offering substantially no obstruction above the latter where by the can may readily ride over the plate. The arm 40 is referably held'in an elevated position whereby to position the plate 42 at an incline above the runway as by a spring arm 43, preferably constructed as shown, the same being secured at one end to a suitable boss 44 projected from the sleeve 39, and

loosely sliding in a slotted support 45 secured to one wall of the receptacle 10. The slot of the member 45 is a terminal one whereby in the removal of the parts the spring 43 may readily be disengaged by a movement lengthwise of the support 45. Suitably pivoted to the arm 40, adjacent the offset upper end 41 thereof, is a dogof any desired construction 46, preferably spring held and adapted at its free end to engage the periphery of the ratchet wheel 38. The operation of this feature of the construction is obvious. A a can moves along the runway, being fed by the belts 5, the same contacts with the plate 42, thereby lowering the plate into contact with the runway and in the lowering movement swings the rocking arm rearwardly, which because of the engagement of the dog 46 with one of the ratchet teeth of the wheel 38, will move the latter preferably one tooth, though this may be adjusted or regulated as desired. It will thus be seen that an intermittent movement to the belt is given each time a can passes 'lap end of the label may be regulated by the "adjustment of the label receptacle on its support, and with this and other objects in view the receptacle 10 is preferably mounted on a support 47 having suitable side flanges 48 constituting guides whereby the receptacle may be bodily moved forward or backward, and when properly adjusted the same is con veniently held in osition as by a thumb bolt 49 passing through a threaded aperture in a suitabl lug 50 intermediate the sides of the receptacle, which bolt 49 at its inner end is adapted to engage over an outwardly extending flange 51 at the lower end of said receptacle 10.

It is desirable to adapt the construction to various machines now in use and with this and other objects in view, it is proposed to permit of adjustment of the support 47 laterally relative to the machine whereby to aline the paste carrying member with the label receptacle.

52 is a suitable bracket support adapted to be secured in any desired manner to the side of the framework of the machine and having at its upper end an elongated bar or bed plate 53. The plate 53 has in its upper surface a recessed portion 54 adapted for the support of a base 55 of the support 47, the side walls of the recess of the plate 53 constituting guides whereby to permit of adjustment of the support 47 longitudinally of said plate 53 or transversely of the machine. In orderv to maintain the support 47 in adjusted position on the plate 53 I preferably provide in the plate 53 an elongated recess 56 in the under surface of the plate and a longitudinally extending slot 57 extending from the free end of the plate inwardly, and adapted to project through said slot and to be secured to the support 47 is a bolt 58 threaded to the support 47 and having a headed end 59 overlying the wall of the slot 57. Interposed between the wall of the recess 56 in the under surface of the plate 53 and the headed end of the bolt 58 is a suitable spring member 60, which latter is adapted to frictionally hold the support 47 in any of its adjusted positions.

The operation may be reviewed as follows: It being understood that the cans are led to the forward end of the runway in the usual manner. the foremost can being fed by the belt :3. will move over thepasting roller 3. thereby receiving an application of paste; which in the continued movement of the can will engage the forward end of the label to pick up the same and in its further movmuent will wind the label thereabout, it being understood that the lapend of the label is receiving an application of paste by the endless paste carrier and that said lap end will be secured to the can by the continued movement of the can, which latter is pressed bythe belt 5 against the usual ironing or pressing pad not shown, at the rear end of the machine. Aszncan moves'into contact with the plates 30, the latter are lowered into contact with the runway, constituting in the lowered position iractically a continuation of the runway, and since the connected parts of the plates are positioned to the side of the runwayand therebelow, they will not interfere with the movement of the can. As the plates 30 are lowered the spring arms carried thereby lower the operative end of the endless paste carrying member into engagement with the lap end of the label, when the plates 30 will be elevated by the springs 99 and the forward end of the paste carrying member with the uppermost label will be likewise elevated by its spring 25. lVhen the endless paste carrying member is in contact with the label, it is stationary, but the same is given an intermittent movement lengthwise while out of contact with the labels, the

same being accomplished by the continued movement of the can which movesinto contact with the plate 42, thereby rocking the arm 40 and through the dog 46 moving the segment wheel 38 and therewith the gear wheel 1:2, which in turn imparts rotary movement to the pinion 13, thereby rotating the roll .16 and the toothed wheels at the:

ends thereof. The said toothed wheels being in engagement with the chains at the sides of the endless paste carrying belt imparts rotary movement to the latter. As soon as the plate 42 has been disengaged by the can in its continued movement, the arm l0 carrying said plate is elevated by the spring 43 to the position illustrated in Figs. l and 5.

'By the peculiar construction of endless paste carrier, it will be observed that the same while flexible from side to side and end to end, whereby it will readily engage" the label, at the same time. the paste-carry" ing member is reinforced at its sides through theimedium of the chain borders,"

thereby overcoming the usual twisting "of the belt in movement and; preventing stretching ofthe same.

In practice the; labels'are usually inserted.

to the ready positioning of the labels in the receptacle. Also as desired, the said lap end pasting mechanism may be bodily removed sidewise from the machine by simply drawing the same out, the guide slot in the plate 53 extending to the cdge'of said plate for this purpose. It will also be seen that the gear connection between the paste roll and supporting roll for the endless paste carrying member of the lap end pasting mechanism is positioned to one side of the receptacle 10, and by removing the members 11 and 46 on the shafts at one side of the receptacle 10, the said shafts may be bodily removed from the opposite side of the recepta'cle. This will free the paste roll 11 and the carrying frame for the endless paste belt. The trip arm -12 may also be removed sidewise of the machineupon removal of the shaft 11, the support for the spring arm 43 connected to the arm 40 having a terminal slot for this purpose.

Referring now more particularly to Figs. 7, 8 and 9, which disclose the preferred form of trip actuated means for moving the belt lengthwise, it will be observed that the gear wheel 12-, together with the intermeshing fpinion 13 is employed as previously described for operating the paste belt 24. Also fconnected for movement with the gear Wheel 12 is the ratchet wheel 38. The means for causing the ratchet wheel to rotate to thereby impartrotary movement to the paste belt in the present embodiment of the invention is somewhat diflerently constructed as fol lows: An upright bracket support 61 is provided, the same being preferably interposed between the ratchet wheel 38 and the adjacent side of ,the paste receptacle, being removably secured to the latter as by screws .62. One member 63, of what may be termed a toggle link, preferably has a bifurcated terminal 63 fitted over the upper end of the support'6l and is pivotally connected thereto, as by a. pintle 64. The other member 65 of the toggle link has connected thereto a pawl 66, the latter being conveniently an integral extension of the member 65. The members 63 and 65 are pivotally con- ,nected, as by apivot bar or red 67 passing through registered apertures in the terminals of said members which lie side by side. Projecting inwardly from the member 63 of the toggle link is a plate 67 which said {plate is lot a len h to overlie the adjacent lrunway and-is a apted in the movement of the can to be engaged by the latter and depressed-thereby, imparting a substantially directdownward movement to the pawl 66,

which being in-engagement with the ratchet wheel 38 will rotate the latter and in turn the gear wheel 12, pinion 13 and the drive sprocket for the paste belt. In erde r to hold the pawl member of the toggle llnk in operative position relative to its ratchet wheel and in order also to maintain the trlp plate 67 in an elevated position to be engaged by the can, I preferably provide a coil spring 68, the latter being sleeved upon the pivot bar (37 and connected at one end to a collar 69 adapted to be secured to the rod 67 as by a screw 70. The opposite end of said coiled spring is connected to the pawl member at 71. The action of said spring is to draw the pawl member inwardly and buckle the members of the toggle link whereby the pawl will be maintained in operative engagement with the ratchet wheel and whereby the member (33 of the toggle link positions the pressure plate G7 above the runway and in position to be engaged by the can. A stop is provided for limiting the upward movement of the toggle link due to the action of said spring, the said stop preferably taking the form of a bracket member 7 2 secured to the support (31 which said bracket member preferably has an adjustable screw 73 adapted to engage the upper surface of the member 63. By adjusting the screw 73 the up ward limit of the movement of the toggle link may be accurately adjusted and positioned. Also to regulate the tension of the spring 68 it is simply necessary to loosen the screw 70 when the collar 69 may be rotated upon the rod 67 and afterward held in adjusted position by the screw 70. In this embodiment of the invention it is preferable to arrange the means for limiting the upward movement of the carrier frame for the paste belt at the opposite end or side of the paste receptacle as illustrated in Fig. 9. This bracket is given the numeral 74 and is adjustably connected at 75 to the side of the paste receptacle having an overhanging arm at its upper end to engage over the swinging frame 17 The toggle link form of trip member has certain material advantages, notably the fact that the same is more easily operated by the passing can due to the substantially direct downward pressure on the member 63 caused by the pressure on the can by the feed belts.

It will be noted that in both embodiments of the invention illustrated, the trip plates 42 and (57 respectively are of a length to overlie the runway bar at that side of the .machine and projecting rearwardly from one side of the trip plate is an inclined ofiset part 42* for the plate 42 and 67 b for the plate 67. This is of especial advantage since it oftentimes happens that a reverse movement is given to the cans on the runway, and should said cans in the reverse movement meet with an abrupt edge, the parts are likely to become broken, whereas in the preslent case the downwardly inclined portions 42 and 67 of the respective presser plates will be enga ed by a can in a reverse movement thereo along the runway and the trip plates will be thereby lowered, preventing injury to the parts.
