TAPE MOISTENING AND PASTING DEVICE Filed Oct. 28. 1927' Patented Mar; .29, 1932 UNITED STATES PATENT- OFFICE CHRISTOPHER JAMES WALBRAN, OF MONTCLAIR, NEW JERSEY, ASSIGNOR TO TELE- TYPE CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE TAPE MOISTENIN G AND PASTIN G DEVICE Application filed October 28, 1927. Serial No 229,870.

The present invention relates to tape mois tening and pasting devices.

More particularly the invention relates to tape moistening and pasting devices especial- 1y adapted for use in pasting telegra h mes sages received on tape or messa e lanks; for sealing package wrappers with adhesive tape, and like uses. v

Objects of the invention are to provide im- 10 proved and simplified tape moistening and pasting devices provided with a single body portion serving as a hand grip and container for water and into which the inner end of the Wick protrudes; to provide moistening and pasting devices arranged for minimum leakage when not in use which facilitate rapid, efiicient, and neat handling of the tape; and to provide such other objectsas may be attained by a utilization of the principles and arrangements hereinafter set forth and as de- 5 ing the guide slot formation.

Referring to the drawings by reference characters in which like characters designate like parts, 1 designates a tubular body which is preferably formed of a transparent material in order that the liquid contained therein may be seen, and in the present instance is formed'of pyralin. The tubular body 1, as is clearly shown in Figure 3, is an open ended structure having one end thereof closed by means of a suitable plug 2 which is cemented therein and a rubber or pyralin protecting cap 2 embraces the end and the plug 2. The opposite end of the tubular body is internally threaded as indicated at 3 in Figure 3 which is adapted to receive the externally threaded end 4 of a removable cap 5', which may be of hard rubber or other suitable material, Cap 5 adjacent its threaded portion is provided with a shoulder portion 6 which is upwardly extended as indicated at 7, and provided with a guide recess or slot 8 (Figure 5). Engaging the shoulder portion 6 is a metallic-washer 9 which is provided with a laterally turned lip 10 adapted to rest in said recess and further provided with upwardly extending projections 10' on either side of lip 10, and a suitable rubber washer or packing member 11 is interposed between the washer 9 and adjacent end of tube 1 to effect a water tight seal between the tubular body and cap 5. The metallic. washer 9 ma be eliminated in which instance only the ru ber washer 11 would be interposed between the cap 5' and the body to provide a leak proof connection.

Cap 5 has rigidly embedded and secured therein, a unitary metallic member 12 providing a .Wick conduit 13 which, as shown in Figure 3 extends from the inner end of cap 5 and projects arcuately upward and outward from the opposite or outer end thereof as indicated at 14, the conduit 13 may be straight and extended upwardly and outwardly from a point adjacent the bottomof the body 1.

The member 12 further provides a tape guide comprising a flanged extension 15 having secured to the base thereof the base portion of a flanged upwardly extending tape guiding members 16 and extending through the flanges of the extension 15 at the outer ends thereof is a shaft 17 on which is supported a tape guiding member or shoe 18.

The wick conduit 13 is adapted to receive a suitable wick 19 which, as shown in Figure 3, has the inner end thereof projecting in-- wardly of the inner end of the cap into tubular body 1 and the outer end thereofis adapted to be' so positioned as to engage the tape when drawn thereon as indicated in Figure 2.

The upper wall of the tape conduit is-provided with a groove as indicated in Figure 4 adapted to extend the full length of the conduit for the purpose of admitting air Without the necessity for very careful fitting of the Wicks necessary when such a groove is loo not provided. A suitable fine mesh screen .21 is positioned between the upper wall of cation of the wick with the groove through.

the mesh of the screen in pasting operations so that the-water in the groove may be absorbed by the wick permitting access of air to the interior of the container as will more fully hereinafter appear.

Detachably supported on tubular body 1 is p a unitary tape guiding and pressure regulating mechanism 22 which in its construction comprises a longitudinally extending tape guide 23 having secured to the under surface thereof a pair of ar'cuate yieldable body engaging members 24 adapted to yieldably engage the body 1 to detachably secure the guide and pressure regulating mechanism thereto. The guide23 is provided with an internal channel 25 adapted to receive and guide the tape 26. The base of the guide 23 extends forwardly of the channelled portion as indicated at 27 and is provided with laterally extending ears 28 adapted to engage the rear sides of the projections 10' to hold the guide anecphalnism against forward movement on Piirtion 27 merges into a thickened angularly extending guide member 27' and rearwardly of the cars 28 the guide 23 is provided with a pair of cars 29 through which extends a pintle 30. Mounted on pintle 30 between ears 29 are ears 31 of, a tape pressure regulating member 32 which, as shown in Figures 2 and 3, is provided at the forward end thereof with a slotted tubular tape engaging member 33 and at the rear end thereof is provided with an angular finger engaging member 34.

The member 33 is normally held in engage- Operation I In operation, the wick 19 and screen 21 are introduced into conduit 13 of cap 5 and body 1 is filled with water after which the cap is screwed into the end of the body causing the inner end of the wick to project into the water in the body. The tape guiding and pressure regulating mechanism 22 is then applied to the body 1 by means of members 21 yieldably engaging the body and the ears 28 engaging the projections 10' which positions the guide member 27' substantially in alignment with the end of the wick as shown in Figure 2. Initially, and also when the device is filled but not in use for pasting purposes water fills groove 20 establishing an air seal which prevents air from entering body 1 andaccordingly prevents water from continually dripping out. 1 i

The tape'26 to be pasted is inserted into channel 25 and drawn therethrough either before or after the guide mechanism is positioned on the body. The tape will then pass over the end of the wick, the tape extending between guide 27' and member 33 passing over the end of the wick, guiding member 16, and under roller 18, as indicated in Figure 2.

When the tape passes over the end of the wick, water is drawn from the wick which in 'turn obsorbs the water from groove 20 through screen 21 permitting air to enter body 1 through the groove allowing the water to pass freely by means of capillary attraction through the wick to be transferred to the gummcd surface of the tape. It will accordingly be seen the recess '20 in conduit 13 admits suflicient air into body 1 to avoid creation of a vacuum'and causmg the water to maintain a level, commensurate with the 7 beyond the shoe 18. The moistened surface is then pressed against the part to which it is to be pasted, such for example. as a message blank or over the edge of a package wrapper and the moistener is moved along.

This action draws the tape from the moistener allowing the tape to be pressed against the message blank or package either by hand or by means of some other ob ect. \Vhen a suflicient quantity of tape has been used it may be torn and the operation repeated. In this way strips of any desired length may be applied rapidly to the message blanks or the package and the tension of the tape may be varied by turning the pintle 30 and putting spring 35 under more or less tension.

The location of the air groove 20 innnediatelv adjacent to the wick 19 serves a very useful purpose when the moistener is not in use and tape is not. being passed over the end of the wick as at the end of a line, and while the succeeding line is being started during which period air would continue toenter the water reservoir and water would drip continuously if the groove 20'were not positioned immediately adjacent to the wick. By positioning the groove 20, as disclosd, the screen 21 permits water to flow through it when the preventing any further flow of water. When tape is again drawn over the end of the wick the water 1n groove 20 is drawn mto the wick, and the groove is thu automatically-freed of water and again acts as a vent permitting air to enter the water reservoir.-

VVhen the moistener is not in use, the tape is lifted oil the end of the wick 19 through engagement therewith of the member 37 by presslng down on the member 34 which member- 34, together with the member 37 upon re- Y lease of the member 34 will automatically assume their original positions but due to a sufficient stifiness of the tape it will remain in the position acquired by the above operation and hence will remain out of contact with the wick until it is desired to again put the moistener into operation.

small section of'tape which would rest on the end of the wick and prevents the choking of the wick due to an accumulation of glue.

It will accordingly be seen that a simple and etiicient moistener and tape paster has been provided which auton'iatically seals against leakage when not in use and lends itself to rapid and etli'cient pasting of tape for various purposes, and which when used for pasting telegraphic tape on messa e blanks permits satisfactory use without soiling of copies.
