a continuous strip labelto the board as it is manufactured, this label containing sales indicia, such as trademarks, patent numbers, etc. Itis important that a machine of this character shouldv apply the adhesive uniformly, so that good bond is obtained between the strip label and the sheet of material. It is also important that a continuous supply of the sheet labels be maintained, sov

that unlabeled boards will not be produced.

An object of this invention, therefore, is to provide an apparatus for applying a continuous strip of labeling material to boards or other sheets which are manufactured in continuous strips.

Another object of the invention is to secure the uniform application of adhesive to the labeling strip.

A further object of the invention is to provide an apparatus of the class described, in which a continuous supply of the strip label is assured at all times; also to improve strip labeling apparatus in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in which :Fig. 1 is a sectional elevation of the strip labeling apparatus,

Fig. 2 is a plan view of the apparatus,

Fig.3 is a sectional elevation of the holder for .rolls of the strip labels, used on either type of apparatus, taken on line 33 of Fig.1. r

The article to be labeled may consist'of a plaster board 10,or other material in sheet form, which passes continuously along a table :11. The strip label12 bearing the de- :siredadvertising indicia is supplied in the 1930. Serial No. 470,575.

form of form rolls 13 which are mounted on 7 reel shafts 14. The reelshafts 14 are prefer ably twoor more in number, and are rigidly secured, one on each end of a pivotally mounted beam 15, which is rotatably secured on a central shaft 16, the latter being rotatably mounted in a bearing bracket 17 secured to the framework 18 of the machine. A roll guideil9 is rigidly secured tothe shaft 14 adjacent the beam '15, by a set bolt 20., Outstanding arms 21 are formed on the roll guide 19 for the purpose of preventing the roll of strip labeling material 13 from telescoping. A. second roll guide 22 is rotatably mounted uponthe shaft 14 and is provided with outstanding arms 23 for supporting the roll 13. The roll guide 22 is quickly detachable from the shaft 1 1. The shaft 1 1 is provided with a slot 25 into which is pivotally mounted by means of pins 26, a pair of catch arms 27 which arev normally urged to spread apart by means of a coil spring 28. Catch shoulders 29 are formed on the outer ends of catch arms 27, these catch shoulders being adapted to engage the outer surface of the roll guide 22, after said roll guide has been slipped over tapered surfaces 30 formed onthe outer ends of the catch arms 27. I A pin 26a limits the portion of beain 15, which engages a similarly shaped notch formed in thebearing bracket 17 The shaft 16 extends beyond the bearing bracket 17 and is provided at'its outer end with a collar 32 which serves to confine a coil spring 33 between said collar and the bracket 17, so that the catch shoulder 31 is normally urged into locking position in, its notch, thus maintaining the beam 15 in substantially horizontal position. When a roll of the strip label become exhausted, the operator quickly disengages the beam lockshoulder 31 from its notch by pulling the beam 7 15 outwardly against the action of spring 33, and then vented from axial movement by: fixed collars 36a. One end of the shaft 36 is pivotally supported in a bracket 37 and the other end ofsaid shaft is receivedin a saddle bracket 38' so that the roll and shaft 36may be easily swung upwardly to permit rapid threading of the strip label throughthe machine.

After passing the roll85 the strip label 12 passes upwardly over aniadhesizve applyingz roll 38 which is rotatably supported, being sec-ured to a shaft-"39 which is rctatably supportech bearings formed on the: outer edges of an adhesive pan 41' into which the roll 38 clips.

A scraper 47- extends transversely over thetop-of pan41, being adjustably secured thereto by set screws 458" and la-sol that the inner edge of said scraper bears against the periphery of the roll 38 and thusprevents an excess ofadhesi-ve frombeingappli'ed-to the surface of'label ing strip-12: j i

The lever 71 is pivotally supported upzoii-a-pivot-pin 72, andthe outer end of said lever is provided with a counterweight 'Zfiservingtourge the roller 70 inka' clockwise direction; as" seen in: Fig. 1 The clockwise movement of lever 72 is limited byf'a stop 74 Air electricali connecting wire- Z5 is connectedtfo the lever-Tl, saidwireleading in series tlLlIOWQliiLHfllfll H-l device su oh as a loci-176; and batteries '57, and then is grounded to framework 18 by electrical wire 78.
