1 Claim. 1

This invention relates to an improved moistening device and has particular reference to a specially constructed device for use in moistening envelope flaps, stamps and other articles coated with adhesive, whereby the adhesive is softened and becomes sticky for sealing the material to the surface intended.

An object of the present invention is to provide a suitable open container forming a reservoir for retaining the desired amount of liquid therein and to provide an enlarged lower roller and a smaller upper roller and to operatively arrange the said rollers in such relation to each other as will cause the peripheries thereof to be in rolling contact, the periphery of the lower roller dipping into the well, whereby a thin film of fluid is carried upward to and in between the peripheries of the rollers for moistening the adhesive on such articles as envelope flaps for sealing the same.

Another object of the present invention is to revolvably support the lower roller in the top surface of the container and to provide a removable clamp on the said container forming a standard that extends upwardly to and around the upper roller for revolvably supporting the said upper roller and retaining the same in the proper operative position relative to the lower roller.

A further object of the present invention is to form oppositely opposed vertical slots in the upper projecting members of the standard for receiving and supporting the shaft of the upper roller, whereby the saidroller is free to rise and move vertically for accommodating different thicknesses of adhesive coated materials to be moistened.

A still further object of the present invention is to knurl or otherwise roughen the outer periphery of the upper roller to facilitate the movement of the adhesive coated materials projected between the rollers.

A still further object of the present invention is to provide a suitable brush or the like directly above the upper roller and secure the same to the standard to function as an auxiliary spreader and to remove surplus fluid from the materials when necessary.

A still further object of the present invention is to provide a moistening device of the character described that is durable, simple in construction, economical to manufacture, positive in operation and highly efiicient and. serviceable in use.

Other objects and advantages will be apparent during the course of the following description. 7 In the accompanying drawings forming a part of the specification, wherein for the purpose'of illustration like numerals designate like parts throughout the same,

Fig. 1 is a top plan view of the improved moistening device,

Fig. 2 is a vertical sectional view taken through line 2-2 of Fig. 1 looking in direction of the arrows A, and

Fig. 3 is a vertical sectional view taken through line 3-3 of Fig. 1 looking in direction of the arrows B. 1

Referring in detail to the drawing and to the numerals thereof the numeral 5 designates as a Whole a container, preferably rectangular-in shape with vertical walls 6, 1, 8 and 9 and a horizontal bottom l0 forming a suitable reservoir I l as shown in Figs. 1 and 2. The top surface of the walls 8 and 9 of the container are formed with oppositely opposed grooves 12 for receiving and supporting a suitable shaft l3, which shaft horizontally extends through an enlarged roller [4 as shown in Fig. 3. The said shaft is preferably fixed to the said roller l4 and the said roller preferably extends in the reservoir In of the container as shown in Fig. 2.

A standard designated as a whole by the numeral i5 is formed with a bottom 16, oppositely opposed vertical end walls I! and I8, which end walls extend inwardly and over the top surface of the container walls 8 and 9 as at I9 and 20. The said standard is preferably formed of a suitable spring metal or plastic and is tightly clamped to the said container and is further provided with upper vertical walls 2! and 22 and a horizontal top wall 23 and a downwardly extending wall 24 as shown to advantage in Fig. 3. The said walls 2| and 24 terminate a short distance from each other at the top of the roller [4, whereby a space 24 is formed for enabling the adhesively coated material to be inserted between the peripheries of the rollers. A roller 25 of smaller diameter than the roller I4 is positioned on the upper peripherial extremity of the said roller [4 and is provided with a fixed shaft 26, which shaft is revolubly supported in oppositely opposed slots 21 and 28 provided in the upper walls 22 and 24. The peripherial surface of the smaller roller 25 is knurled or roughened as at 29 to facilitate the movement of the materials projected between the rollers. The numeral 30 shown in dot and dash lines designates a piece of material such as an envelope flap coated with an adhesive substance on the other side, when the material is positioned between the rollers and is pulled past the same, the weight of the top roller 25 resting on the said material 30 and lower roller M will 5 cause revolvable movement to be imparted to the rollers whereby fluid fromwithin the reservoir II will be "fcarried on the lowr rdller hi to moisten"'the"adhesive coating "on" the "said "ma terial. As the smaller upper roller 25 is posi 10 tioned in the oppositely opposed slots 21 and 28 and rides on the periphery of the lower roner I4 it will be obvious that the said smaller roller will raise when the materi" o"be""moiste'ried"'is inserted between the rollers,'wiireb different? 5" thicknesses of materials are accommodated.

A brush 3| having a back 32" is fix ed tci the top face of the cross member 23 of the standard and is provided as an auxiliary spreader to 'be ass merely rubbed overthe brush to accGin'pIiSh the piii' po'se iri'te'iidedi The container Band therollers i4' aridz5f-re' used in conjunction with the rollers when it is 20 A device 01' the character described for use in V moistening the adhesive coated substance for envelope flaps and the like, comprising a container forming a fluid reservoir with an open top, a lower roller revolvably supported on the upper portion of the container and extending in the said reservoir, an upper roller resting on the periphery of "th'e lower frollr' and pdsitioned in parallelism therewith, tif said ripper roller being ot a smaller diameter than the lower roller, a slfaft horizontally fixed to the upper roller, and
