11 Claims. 1

This invention relates to moistening devices for tape-dispensing machines, and more particw l'arlyto a device wherein a strip of gummed tape is designed to be passed over a brush or other moistening element immersed in a tank of "water, so that the 'gummed side of the tape will be properly moistened for application to a package or parcel.

Such devices ordinarily comprise a frame of some kind for holding a roll of tape and a receptacle either formed integrally with the frame or detachably mounted therein for holding *a supply of amoistening fluid, such aswater. A'brush or other moistening element is mounted in the tank so that it is immersed in the water and the latter carried to the tip ends of the bristles by capillary attraction. The tape is drawn or fed through suitable guide means overthe end of the brush or moistening element so that its gummed side will contact therewith.

Usually the tank or receptacle ffo'rthe moistening liquid is provided with a cover, "and this cover usually engages one side of the brush to support the same in proper position, it being necessary to remove the cover in order to refill the receptacle.

It very often occurs that, when the cover is removed for this pur ose, it is mislaid priest and occasions considerable inconvenience and delay in finding the lost cover 'or securing another as it is necessary to have the'coverin place to secure proper moistening "by the "brush when the cover serves as a support -'for the brush.

One object of the present invention to -overcome the disadvantages referred to above and provide a cover for the receptacle of a tape d ispensing machine which may be readily moved to an out-o-f-the-way position to permit refilling of the receptacle or re-adjustment of the brush, and, at the same time, the cover will remainconnected to the device .so it will not be lost.

A still further object of the invention is to provide a cover for the receptacle of .a tape-- dispensing machine, which cover will be permanently connected with the receptacle and, at the same time, movably connected therewith, so thatv it may be readily moved to uncover the receptacle for any desired purpose.

A still further object of the invention :is to provide a cover for the receptacle of a tape-dls pensing machine, which cover will be movably connected with the receptacle so that it may be retracted to an out-of-the-way position, and, at

the same time, will be adjustably mounted sothat it may be 'moved to adjusted position relatively to the moistening element and retained in this position during the operation of the machine.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings:

Fig. 5 is a side elevational view of the front portion of a tape-dispensing machine showing a modified form of my invention;

Fig. '6 is a top plan view thereof;

Fig. 7 is a sectional view on line l'! of Fig. 6; and

Fig. 8 is a view similar to Fig. 7, but showing the cover in another position.

To illustrate one embodiment of my invention,

I "have shown a tape-dispensing machine comprising a frame or 'body [0 designed to rotatably support a supply roll of tape 'H in any suitable manner well-known to those skilled in the art. Upon the frame mounted a-guide plate or table. 12, and disposed above this plate and in spaced relation theretois a tear-off blade :l'3,.so that the tape issues from the machine between the members -'I 2 and 13.

A moistening element, such as the brush J4, is illustrated as supported in a receptacle l5 for;

the moistening liquid, suchas water. In this instance, the receptacle is formed integrally with the body of the machine, although it maybe separately formed if desired.

Thisrecepta'cle is open at the top and is adapt ed to be covered by the cover member 16., shown in :Fig. 4. at its forward'ed'ge with alip ll turned upwardly and preferably slightly rearwardly therefrom,

which lip bears against the brush f4 and presses it against the plate [2.

As previously stated, it is desirable to be able to remove the cover from the receptacle and,

at the same time,' prevent the cover from becoming mislaid or lost. For this purpose, the walls of the frame or body at the front end thereof, which are also the walls of the receptacle l 5,.maybe provided with pins i8 and is designed to cooperate with slots formed in parts of the,

his cover member may be provided cover as will be presently described to secure the cover detachably in place.

At each side of the cover i6 is a depending flange 20 which may be formed integrally with the cover, each of these flanges bein provided with a slot 2i opening through its rear end to receive the pin 48 and with a slot 22 having closed ends to receive the pin l9. As will be apparent from Figs. 1 to 3, the slot 22 comprises an elongated body portion substantially parallel with the lower edge of the flange 29 and an upwardly and rearwardly turned end portion 23. It will also be apparent that the slots 22 are closed at both ends, so that the cover will always remain in engagement with the pins l9.

In the closed position of the cover, the parts are in the position shown in Fig. 1, wherein the pin I8 is received in the open-ended slot 21, and

the pin I9 is disposed within the rearwardly bent rear end 23 of the slot 22. The lip II will press forwardly against the brush l4, and this pressure will tend to hold the cover in place as the latter must be moved toward the brush to a slight extent in order to efiect registration of the pin [9 with the elongated body portion of the slot 22.

When it is desired to remove the cover from the receptacle, the cover is raised and moved toward the brush to a slight extent until the pin is lies in the elongated slot 22. The cover can then be moved rearwardly and permitted to drop pivotally about the pin I9 to the position shown in Fig. 3, Where it will be in an out-ofthe-way position so far as the receptacle is concerned and yet will still be attached to the receptacle so that it cannot be mislaid or lost.

In replacing the cover upon the receptacle, it is moved pivotally about the pin l9 and then moved forwardly until the pin [8 is received in the slot 2! and the pin [9 is in position to enter the slot 23. The rear end of the cover is then moved downwardly to a slight extent, thus moving the pin l9 into the slot 23 and restoring the parts to the position shown in Fig. 1.

The engagement of the pin ill in the slot 2! holds the front end portion of the cover securely in position and prevents this portion of the cover being raised by the operation of drawing tape from the machine.

In Figs. 5 to 7 of thedrawings, I have shown a slightly modified form of my invention wherein the cover may, in its operative position, be adjusted relatively to the brush so as to exert more or less pressure thereon in order to control the capillary action as desired, or to provide adjustment for varying thicknesses of brushes. Also, in this form of my invention, the receptacle is shown as separately formed and detachably disposed in the main frame of the machine, although it will be understood that this form of cover plate may also be employed with a receptacle formed integrally with the frame of the machine.

The frame or body of the device is shown at 25 and is provided with a seat 26 upon which may rest a separately formed receptacle 21. Within this receptacle is seated a brush 28 against which bears the upwardly and rearwardly bent lip 29 of the cover plate 30. The receptacle is provided upon the outer face of each side wall thereof with a pin 3| and a lug 32 having teeth or detents 33 upon the upper surface thereof.

The cover plate 36 is provided at each edge with a downwardly depending flange 34, each flange being provided with a relatively short slot 35 opening through the rear edge thereof and adapted to receive the pin 3| and with an elon- 4 gated slot 36 in which the lug 32 is adapted to be received.

At the upper front portion of the slot 36 are provided a plurality of teeth or serrations 3'! designed to engage with the teeth 33 of the lug 32 so as to hold the cover plate in adjusted positions upon the receptacle. It will be obvious that it is only necessary to raise the front end of the cover plate slightly, thus disengaging the teeth 31 from the teeth 33, and the cover plate may be moved to a new position to adjust the lip 29 with respect to the brush 23. After such adjustment, the teeth 31 may be re-engaged with the teeth 33 and the cover plate will be securely held in adjusted position.

When it is desired to remove the cover plate from the receptacle, the front end thereof is raised slightly to disengage the teeth 31 from the teeth 33, and the cover plate is moved rearwardly, thus disengaging the pin 3! from the slot 35. It will be noted that the lug 32 is of such size that it will move freely through the slot 26 and, when it reaches the rear end of this slot, the cover may be dropped downwardly in the position shown in Fig. 8 of the drawings, where the receptacle will be completely uncovered, but the cover will still be attached to the receptacle by the lugs 32.

At the front end of the frame 25, the walls of the machine may be cut back to some extent, as shown at 38, in order to provide more room, if necessary, for the projecting lugs 32 and also to render the front part of the cover accessible for manipulation.

While I have shown and described some preferred embodiments of my invention, it will be understood that it is not to be limimd to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claims.
