LABELING-MACHINE:-

ap licationfiled May'29, 1919. Serial 1Tb. 300 719.

To all whom it may concern: I

Be itknown that I, GEORGE S. Monms, a citizen of the United States,- residing at. Jackson, in the county'rof Jackson andState of h Iicl1igan,. lrave invented a certain new and useful Improvement in Labeling-Machines, of which the following is a full, clear, and exact description, reference being: had to the accompanying drawings.

An object of this invention is to provide a mechanism to prepare labelsfor applica tionto the articles which are of suchshape and size that they do not lend themselves readily to beinghandled by label applying mechanism. In other words, this invention is to facilitate the application of labels to such articles by hand and relates particularly to a machine for preparing of the labels by applying paste thereto, and presenting the labels to an operator for appli cation toarticles. being handled manually.

The methods heretofore practised fo'rap plymglabels to articles of shapes not'conveniently handled by a macliine for the aua tomatic application of labels, usually include the'spreadlng of the labels overa large table-and applying 'paste'to the labels on' the table by the use of ab'rush'; and then picking up the labels by hand one'atlatime and applying them to thearticles. This method. is practisedfor applying labels to agricultural tools', such as-hoes, rakes, forks and the like, and involvedconsiderable waste of time in bringing thefarticles to a position immediately adjacent thetable and in*re'ach ing for the labels which must be very ca'refully picked up and wrapped around the handle of the forkorhoe' or sinlil'ariinplement. Amore specific object of this invention is to provide machine for automati cally taking the labels from a'pile and conveying them to a piosition immediatelyadjacent to arack: or frame forholding' alarge nlnnber of the implements to be labeled, and presenting the labels toi an operator so thathe may pickthem up. with"a minimum amount ofmovementof the hand and without difiiculty in grasping them or removing them fronrthe surface onwhieh they are carried.

In the useo-f the prese11tinethods of labeling such-articles it hasbeen proven that the greatest amonntrof timedslost in apply ing the paste and in :eachi-n g "for and picking up the labels;- Accordmgly the speed at which these labelsmay be applied may-be paste receptacle: showing very greatly increased by the use of a mach ne such as comprises the subject matter of this invention.

Additional objects of the invention are to construct such a-machil'ie that-it may be very simple, durable and capable of beingcheaply manufactured and effective in operation.

I have illustrated a convenient embodimentof my invention in the drawings hereof. The method of accomplishingthe above andotherobjeets will become more appare'nt S pecifie ationof Letters Patent. Patgnted'ifune 1920 in the following description which relates to the drawings. The essential characteristics are summarized in the ClitlIIlS.

. In the drawings, Figure 1 is aside elevation ofthe machine embodying my inventlon- Fig. 2 is aplanof the same; Fig. 3 is an end'eleva-tion ofthe machine; Fig. 4 is a detail in the nature of a section of the label supporting device with parts inelevation; F 1g. 5*is a side elevationof the left hand end ofthe machine as shown in Fig. 1, illustrating some of the parts in different positions; Fig. 6 is a sectional detail through a paste applying rollers therein. j Describing the parts by use ofre'fer'ence characters, the frame of, the machine has corner posts designated 1. Secured to the upper" ends of i the'posts are longitudinal structural members 2. Transverse members 4t=each connect and brace adjacent corner posts, while the structural members 2 are connected by plate-like strips '5, 6, 7, 8 and 9, each of which have functions of carrying parts of the 'machine.

' The lower portion .of the frame'is longitu ported in bearing blocks 17 and 18 fixed to the frame plate 5. The pulley. '15 isfshown asmounted on ashaft=20 supported in bearing blocks-21 and 22. Thesebearing' blocks are slidably fittedto plates 2 1- and 25 respectively, inoun ted on the frame plate 9,

which is threaded a screw 27 rotatable in on the screw, whereby rotation of. the screw m'aymove the bearing blocks 21- and 22' car- ,andare'connected by a crossmember 26 into bearings .2812LI1Cl having a handwheel 29.. Between thebearings '28 is a collar 30 rigid rying the shaft 20 and pulley 15 longitudinally of the machine to adjust the tens on of the belt 12.

The belt may be intermittently progressed so that its upper reach moves toward the left hand end of the machine by a suitable step by step mechanism. 1 have shown on the shaft 16 a ratchet wheel adapted to be engaged by a downwardly projecting dog 33 rigid, with the upper end of an arm 34 rotatably embracing an eccentric member 35 of a drive shaft 36. The drive shaft 36 may be constantly driven by any suitable means, which will result in rotating the pulley 14 by a step by step movement. The

dog 33 preferably moves from one tooth to the next of the ratchet 33 and is urged into such engagement by a spring 38, connected with the arm 34 and the frame of the machine. The drive shaft 36 is shown as having bearings 39 mounted on the frame member 10.

Bracket arms preferably formed of heavy fiat metal strips are indicated at 40 as extending over the top of the frame member 2 adjacent to the belt 12, then downwardly to support a paste receptacle 42 shown as carried on a plate 43 adapted'to rest on outward extensions of the bracket arms 40. Below the bracket arms 40 are bearing brackets 44 secured thereto and carrying separated parallel shafts 45 having at their ends intermeshing gears 47. A cam arm is rigid 011 the shaft adjacent to each end of each shaft as indicated at 48 and 49. These arms are rounded at their outer ends as 111- dioated in Fig. 3, and are adapted to engage the plate 43 supporting the paste receptacle to raise or lower the receptacle as the shafts are rotated. This rotation may be accomplished by means of a. handle 50 on one of the shafts. Guide pins 52 are shown as carried by the plate 43 and extend downwardly through the bracket arms 40, to guide the receptacle and prevent it from lateral or longitudinal shifting while permitting its vertical movement when raised by the arms 48 and 49.

lVithin the receptacle 42 is a cylindrical drum 54 011 a shaft 55 carried in' hearings threaded through nuts 64 embracing a transverse frame strip 7 which projects from the frame a sufficient distance to provide for the bearings 63 embracing the roller 62 and allowing the roller to be the width of the belt, as are the

rollers

54 and 60. The roller 62 is shown so positioned as to come between the

rollers

54 and 60. The belt is arranged to travel between

rollers

54 and 60 on the one side and the-roller 62 on the other.

Adjacent to the pulley 14 and normally bearing against the lower reachof the belt is a platen carried by vertical supporting rods 72 extending through and adjustably secured to an extension of the transverse plate strip 6 by nuts 74. The labels to be applied to the articles, and which are presented by the belt 12' to the operator, are first mounted in a stack at on a plate 81 formed on the upper end of a vertically reciprocating plunger 82, slidably fitted in a casing 83 carried by a supporting bracket 84 mounted on an adjacent member 10. In the lower end of the casing 83 is a plunger 85 having a lateral projection movable in a vertical slot in the casing and carrying a roller 86 while a spring 88 is interposed be tween the plunger 85 and the plate 81 as shown particularly in Fig. 4. The roller 86 is adapted to be acted upon by an actuating cam in the nature of a short radial arm 90, mountedon the shaft 36, whereby the plunger 85 may be moved upwardly, moving the plunger 82 and plate 81 with the labels 8O thereon, to urge them, against yielding pressure of the intervening spring, against the belt 12 at a point where it is supported against deflection by the platen 70.

Surplus paste" on the belt 12 may be removed by a scraper 92, preferably set to bear against the belt as it turns over the pulley 14 and arranged on an angle whereby its arcuate inner edge 94 (as shown particularly in Figs. 1 and 2) may closely fit the belt for its entire width and at the same time be presented to the belt at an angle with relation to its direction of travel. This scraper 92 is shown as securedto one end of oneof the frame members 2. The paste so scraped from the belt may fall into a receptacle 96 directly'beneath the scraper and carried on a supporting arm 97 projecting from a corner post l'ofthe frame.

The advantage. of the use of this machine andm'anner of gaining the objects herein set out are made more clear by the following description of the operation of the machine. 1

Assuming, for example, that the operator desires to apply labels to the handles of a large number of hoes, any suitable support in the nature of a rack or other device (not shown) is provided wherebyhe may reach for the article with one hand and most conveniently reach theupper surface of the belt just .as it turns downwardly over the pulley 14 with the other. The paste reforwardly along the upper reach of the. belt tothe operator. The intermittent movement of the belt allows only enough time" tOlQIHOVG the labels from theupper reach of the belt at a point nearest the operator, that a is, just above the pulley 14. Thus the'arti usages-*- ceptacle having been suitably filled with adhesive material of the character and con sistency desired, the handle is operated to raise the receptacle through the cam arms 48 and 4-9untilthe rollers 5eland '60 engage the belt, as shown in Fig: 51* The roller 62' engages the upper sideof the belt between these two. rollers at a point between the contact points of the rollers 54 and and pre- -vents undue deflection, and allows ready adjustment of the pressure of these rollers on-the-belt, by raising the paste receptacle through the mechanism described the desired amount; A pack or stack of the labels to be used "is-then arranged as at 80 on" the platform 81. Now the application of power to the shaft 36 actuates the arm 34 and dog 38 causing it to advance the ratchet wheel, 32 and intermittently rotate'the pulleynli accordingly advancing the belt. This same rotation of the shaft36'also causes the cam arm 90 to engage the roller 86, raising-the pliiuiger" and presentingthe stack of labels to the under side of the belt. The surfaceof the belt'ca'rries' a'smallamount of paste which may be applied, to startjthc operation, by manually-moving the belt past the paste applying rollers. The paste applying operation is automatic thereafter. 1 The surplus paste is scrapedofi' by the scraper 92 and falls into the receptacle 96, leaving a comparatively thin film. 'of' paste on the surface of this'belt, which is-preferably of rubber or like material, at least being pros vided with a non'absorbentslightly yielding surface. This film of paste is just su'fii'c'ient to causetho uppermost label; which is presented with its printed side toward the belt, to adhere thereto but is notsulficient to deface or blurthe matter on th'el'abel. These labels thus secured to the belt pass over the roller 54, receiving a considerable amount of paste which covers the under surface of the label. As the operation continues labels continue to be applied, andadh'ering to the belt, pass upwardly over the pulley 15 and do to which the label is to be applied may be grasped by one hand and" the label by the other and quickapplication' may be accomplished. During the interval of apply-f ingthe label by hand, the belt is advanced to present the next label to him. After the label is removed the paste is then not "evenly distrilnited on the belt owing to application ofpaste over the area surrounding the labels aswell as on the blank surface of-thelabel; As each portion of. the belt passes the scraper, however, the surplus paste is re moved andthat remaining on the belt is side of the labels. The eccentric 35 and cam 90 are so arranged on the shaft that'the plunger is downwhile the belt is being advanced and the belt is stationary when the plunger is'moved upwardly to present labels .thereagainst,.so that the uppermost label of the stack may adhere to the belt andthe stack may not be otherwise disturbed by any lateral motion, such as would occur if the belt were to move while the stackwere in contact therewith.

The paste. receptacle is preferably shown longitudinally shiftable on the plate 43, there being a stop 100 in the direction toward which it tends to move with the movemento-f the belt, butan additional=adjustment of the r0ller's54t an'd60 may be had with relation to the roller '62, by longitudi nally shifting the paste receptacle on theplate 43, forwardly from the stop asshown in l 'g. 6. The roller 60 obtains the proper pressure on the belt by, slight distortion from its normal course-and also evenly dis-- tributes thepaste thereto.

From'the foregoing description, it will be seen that I have provided a machinefor presented; -T-he invention lends itself to many adjustments and adaptations of this character, and itis found that one operator mayapply very many more labels, in *fact several times asinany labels, in a given length oftime as by the handmethod of applying paste tolabels-and. picking'them from large table platform- I aving thus describedmy what I claim is:
