Application January 7, 1947, Serial No. 720,666 (o1. 216-29) 9 Claims. 1

This invention relates to new and useful improvements in a gummed tape applier, and has particular reference to a portable, hand operable gummed tape applier.

The principal object of the present invention is the provision of a hand operable gummed tape applier whereby gummed tape contained on a roll within said applier is pulled from said roll, moistened, applied to a package or other surface under pressure, and cut off at any desired length.

Another object is the provision of a gummed tape applier adapted to be used in any desired position, and to apply tape even to vertical or overhead surfaces.

Further objects are economy and ruggedness of construction, and simplicity and dependability of operation.

With these objects in view, as well as further objects which will become apparent during the course of the specification, reference will be had to the drawings, wherein:

Figure l is a side elevation of a gummed tape applier in operative relationship to a package, shown in the tape applying position in solid lines and in the tape cutting position in dotted lines.

Fig. 2 is a vertical mid-section of the tape applier shown in Figure 1.

Fig. 3 is a sectional view taken on line IIIIII of Figure 2.

' Fig. 4 is a fragmentary vertical section taken on line IV-IV of Figure 2.

Fig. 5 is a fragmentary horizontal section taken on line VV of Figure 4.

Fig. 6 is an enlarged fragmentary vertical section taken on line VIVI of Figure 1.

Fig. 7 is an enlarged fragmentary side elevation of the forward portion of the reservoir handle, detached from the applier frame.

Fig. 8 is a vertical section taken on line VIII VIII of Figure 7.

Like reference numerals apply to similar parts throughout the several views, and the numeral I0 applies to a frame comprising a single piece of sheet metal bent to form two spaced apart side walls I2 joined by a connecting portion M at the upper edge thereof.

A shaft I 6 extends between and is rotatably carried by side walls !2 adjacent'the forward edges thereof, and a pressure wheel i8 is rigidly mounted on said shaft between said side walls. The rim 20 of said wheel is of greater width than the gummed tape to be applied, and carries a tire 2.2 of rubber or other soft, resilient material. Said tire is crowned slightly in order that tape passing around said wheel will seek center.

2 A shaft 24 extends between side walls l2 and fixed thereto adjacent the rearward edges thereof, carries for rotation a moistening roller 26. Said roller comprises a hub 28, a plurality of spaced stiffener discs 36 rigidly fixed to said hub, and a quantity of wicking 32, or similar material, filling the space between said discs and extending outwardly past the edges of said discs. Roller 26 is positioned to engage wheel I8 with a light pressure.

Two spool support arms 34, clamped at their lower ends to side walls I2 at the upper edges thereof by means of bolt 36, extend upwardly therefrom. An axle 38 extends between and is supported bythe upper ends of said support arms, said axle being adapted to pass through the hub cc of a spool 42 of gummed paper tape. Said spool is centered on said axle by a spacer washer 44 and friction disc 46, said washer and disc being carried on said axle on opposite sides of spool 42, as shown in Figure 6. Said friction disc is compressed between hub 40 and a support arm 34, and serves to maintain a tension in the tape as it is unrolled from said spool.

From said spool, tape 50 is passed through a centering guide 48 carried on bolt 36. Said guide, as shown in Figures 4 and 5, comprises a U-shaped member of a slightly greater width than tape 58. Bolt 36 passes through the legs of said guide, and said guide is centered longitudinally on said bolt by means of a pair of spacer bushings 52.

A U-shaped blade support 54, the forwardly extending legs of which are pivotally attached to side walls 12 adjacent the lower forward corners thereof, carries at its rearward edge a centrally mounted blade 56, said blade extending upwardly and havingat its upper edge a notched cutting edge 58 parallel to the shaft 1 6 of wheel !8. Said blade is adapted by the pivotal movement of support 54 to be moved into contact with wheel l8 at. a point just below the point of contact between wheel l8 and roller 26. Notches are cut in the lower edges of side walls [2 to permit free movement of blade support 54. The pivoting arc of said blade away from wheel i8 is limited by stops 62, cut from the forward edges of side walls l2 and bent outwardly to extend above and limit the upward movement of the extended forward ends of blade support 54.

A reservoir handle 64 is removably attached to frame It by means of screw 66 and bolt 68, and extends rearwardly from said frame. Said handle'comprises a body portion H1 enclosing a water chamber 12, saidbody portion being ex- 5. A gummed tape applier comprising a frame adapted to carry a roll of gummed tape, a pressure wheel rotatably carried by said frame whereby tape is drawn from said roll and applied under pressure to any surface with which said pressure wheel is rolled in contact, a moistening roller rotatably carried by said frame, engaging said pressure wheel and adapted to be driven thereby, a handle portion carried by said frame, said handle portion comprising a water reservoir having a sealable filling opening and a cup portion extending beneath and partially encircling said moistening roller, and a resilient porous pad contained in said cup and formed to contact a portion of the periphery of said moistening roller, said pad receiving water from said reservoir through an opening provided in the forward wall of said reservoir adjacent the bottom of said cup.

6. A gummed tape applier comprising a frame adapted to carry a roll of gummed tape, a pressure wheel rotatably carried by said frame, whereby tape is drawn from said roll and applied under pressure to any surface on which said pressure wheel is rolled, a moistening roller of porous absorbent material rotatably carried by said frame and operatively engaging said pressure wheel, a handle portion carried by said frame, said handle portion comprising a water reservoir having a sealable filling opening and a cup portion extending beneath and partially encircling said moistening roller, and a resilient porous pad contained in said cup and formed to contact a portion of the periphery of said moistening roller, said pad receiving water from said reservoir through an opening provided in the forward wall of said reservoir adjacent the bottom of said cup.

7. A gummed tape applier comprising a frame adapted to carry a roll of gummed tape, a pressure wheel rotatably carried by said frame whereby tape drawn from said roll is applied under pressure to any surface on which said pressure wheel is applied, means carried by said frame for moistening the gummed side or said tape before it is applied to said surface, a handle for said frame whereby said pressure wheel is manually rolled along said surface, and a blade carried movably by said frame and operable by the movement of said handle toward the surface to which tape is being applied to out said tape at any desired length.

8. A gummed tape comprising a frame adapted to carry a'roll of gummed tape, a pressure wheel rotatably carried by said frame whereby tape drawn from said roll is applied under pressure to any surface on which said pressure wheel is rolled, means carried by said frame for moistening the gummed side of said tape before it is applied to said surface, a handle for said frame whereby said pressure wheel is manually rolled along said surface, a cutting blade pivotally carried by said frame adjacent the lower edge thereof and adapted for movement toward the tape as it moved around said pressure wheel, whereby when said handle is moved toward the surface to which tape is being applied, the back of said blade is moved into contact with said surface, and the cutting edge of said blade is forced into contact with said tape on said pressure wheel, cutting it off at any desired length.

9. A gummed tape applier comprising a frame adapted to carry a roll of gummed tape, a pressure wheel rotatably carried by said frame, a resilient tire carried by said wheel whereby tape drawn from said roll is applied under pressure to any surface on which saidpressure wheel is rolled, a moistening roller of resilient absorbent material rotatably carried by said frame engaging said tire and adapted to be driven thereby, whereby the gummed side of said tape is moistened, a handle member removably secured to said frame, said handle member comprising a water reservoir having a sealable filling opening and a cup portion extending beneath and partially encircling said moistening roller, a resilient porous pad contained in said cup and formed to contact said moistening roller about a portion of its periphery, said pad receiving water from said reservoir through an opening provided in the wall of said reservoir adjacent said pad, and a cutting blade pivotally carried at the lower edge of said frame and adapted to be moved into contact with said tape as it passes around said pressure wheel, whereby when said handle is manually moved toward the surface to which the tape is being applied, the back of said blade is moved into contact with said surface, and said blade is forced into contact with said tape, cutting it off at any desired length.
