The: wiresid 9, at the right end of the machine are detachably msupported-innotches:28 in across rib 2 1,- formed upon a vertical transverse plate 22, int egral"with the base 5. .zThe plate 22' is; provided with-nan integral flat-gincli-ned table 23, the free end-of -.-which terminates: adjacent the contacting :points of the. rollers ,I hand I 4. :The ireslQlpass-bertweenithemollers Ill and M -andhave their opporqsizteaterminal; ends detachably seated in notches 1 Zllrformeddn: :ri'bs =25, formed integral -,-with-;an .-,upstandingtransversely arrangedplate 2 8. -The J--Wires :19 are inclined in parallel relation throughwout; theirelength"corresponding tozthe inclination roof. the,:talole 123: and-have. contact-With the .table erstufajceithroughoutits length. esince-iiteis essen- :tial ifor" ztheipropem moisteningand/:on'ggummlpg of labels;rthatxthe rollers1have fulLcontact-with the upper surface of the label, the roller H is circumferentially grooved for each of the wires l9 to a depth equal to the diameter of the wires, see particularly Figure 6. Thus, the label, being fed from the table 23 between the rollers, will have its gummed side, or side to be gummed exposed in contact to the knurled side of the roller ll unobstruced by the wires IS. The wires l9, after engagement in their several notches, will be held suitably taut throughout their length.

It is highly important, that means be provided to prevent the labels from following the combined pressure and feed roller l4 during the feeding action. Therefore, to assure a proper passage of the label between the rollers, a plurality of wires 21, similar in number and diameter to the wires I9 and in vertical alignment therewith, engage in circumferential grooves 28 of the roller 14 to lie flush with the surface of the roller in use. The wires 2'! extend outwardly from the contacting surface of the roller [4 and are inclined upwardly to pass about cross bars 29, after which they are inclined inwardly toward the roller i and again engage in the grooves 28. The bank of wires 21 with the wires l9 form a cage-like guard in wedge shape for facilitating the entry of the label between the rollers and a similar guard upon the discharge side to prevent the moistened or gummed label adhering to and following the roller I4, thus causing the label to pass freely upon the supporting wires 19. One bar 29 is grooved at 30 for the reception of a squeegee 3|, engaging the side of the roller M for its entire width. The squeegee is inclined transversely to more readily conduct collected water or adhesive from the roller to be directed to the reservoir HI. As clearly shown, the roller II is partially submerged in the fluid of the reservoir and as the roller l l revolves, fluid is picked up by the knurled surface to be brought into contact with the underside of the label. While the roller II has been shown as being knurled, it will be obvious that a plain surface roller may be em- .ployed and will function to a high degree of success.

In the use of the device, water having been introduced into the reservoir to the proper level and assuming that pre-gummed labels are to be moistened, a label is placed upon the table 23 with the gummed surface down. The crank is then rotated in a clock-wise direction to cause the entire surface of the roller H to be coated I with water, after which the label is shoved to the point of engagement with the rollers. A continued rotation of the crank causes the label to be fed between the rollers H and I4. During its passage over the roller H, Water that has been picked up by the knurled surface is applied to the gummed side of the label and the label passes outwardly upon the wires [9, where it can be easily picked up with the fingers of the operator. The wires 19 are close enough together to prevent the label dropping therebetween, yet far enough apart to permit the insertion of the fingers beneath the label for removal. Any tendency of the label to adhere to and follow the roller I4 is prevented by the wire cage formed by the wires 21. Any water that has collected upon the surface of the roller I4 is removed by the squeegee 3| prior to its contact with the upper side of the label. Thus, the roller I4 at all times presents a relatively dry feed and pressure surface for the label. The operation of the device is identical when employing an adhesive in the reservoir 10 for use on ungummed' labels.

While the machine has been illustrated for use in moistening gummed labels, it may readily be adapted to the moistening of strip gummed paper fed from a roll of such paper suitably mounted at one end of the machine to be fed between the rollers II and M as desired.

It will be seen from the foregoing that a very simple and efiicient form of applicator has been provided for both gummed and ungummed paper labels. The structure is relatively cheap to manufacture, since the base and its associated parts can all be easily cast in a single unit from metal, plastic or other suitable material. The rollers may likewise be cast from plastic or other light inexpensive material, since wear thereon is negligible. All parts can be easily and quickly assembled or disassembled for purposes of cleaning or replacement. The device will quickly and completely apply an even coat of moisture over the entire surface of the label by a single passage of the label between the rollers, leaving no bubbles or dry spots so commonly encountered by the usual hand applicators now in use and presents the label ready for application without in any way soiling the printed side.

It is to be understood, that the invention.is not limited to the precise arrangement shown, but that it includes within its purview, whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim is:
