2 Claims. (Cl. 164-36) This invention relates to new and useful improvements and structural refinements in dispensers for tape, such as for example, tape with pressure-sensitive adhesive of the so-called transparent or Scotch variety, or the like, and the principal object of the invention is to facilitate longitudinal separation of the tape into a plurality of strips of predetermined widths, while the tape is being drawn from its roll.

This object is achieved by the provision of the instant dispenser which includes a holder for a roll of tape and an extension on the holder provided with a prong or prongs with which the tape may be engaged and separated into strips while it is" being drawn from the roll.

An important feature of the invention resides in the provision of means for separating the tape selectively into a predetermined number of strips of predetermined width, and dispensing the tape in its full width, without longitudinal separation.

An additional feature of the invention resides in the provision of means for expeditiously presetting the separating prongs so as to produce the required number of strips of the required width.

A still further feature of the invention lies in the provision of a tearing edge on the holder, whereby the separated strips may be simultaneously tornyaway from the tape in the roll.

An important advantage of the invention lies in its simplicity of construction, convenience in operation, and its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of the invention;

Figure 2 is a cross sectional view, taken suhstantially on the plane of the line 2-2 in Figure 1;

Figure 3 is a cross sectional view, taken substantially on the plane of the line 3-3 of Figure 2, and illustrating the separating prongs in their retracted position so as to facilitate drawing of the tape from the roll without separating the same into strips;

Figure 4 is a cross sectional view, similar to that shown in Figure 3, but illustrating the prongs in position for separating the tape;

Figure 5 is a perspective view of a modified embodiment of the invention;

Figure 6 is a side elevational view of the embodiment shown in Figure 5, and

Figure '7 is a 'cross sectional view, taken substantially on the plane of the line ll in Figure 6.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, more particularly to Figures l-4 inclusively, the invention consists of a tape dispenser designated generally by the reference character I ii and embodying in its construction an elongated body I2 constituting what may be referred to as a holder for a roll of tape I4 which is releasably and replaceably positioned in a suitable recess l6 with which the body I2 is provided.

To this end, the opposite side walls of the recess [6 in the body I2 may be formed with mutually opposed, downwardly extending slots [8 terminating in lateral bays 2o which, in turn, constitute seats for the end portions of a shaft or pin 22 by which the roll of tape I 4 is carried.

One end portion of the body 12 constitutes what may be referred to as an upward extension 24 which terminates at the upper end thereof in a pair of spaced guides 25 defining therebetween a passage for the tape, indicated at 28 in Figures 2, 3 and 4.

The guides 26 are provided substantially at the level of the passage 28 with a pair of axially aligned openings or apertures 39, while the extension 24 itself is provided with a transverse bore 32 extending parallel to the axis of the openings 39, as will be clearly apparent.

A pair of rods 34, 36 are slidably positioned in the openings 38 and the inner, and the mutually opposed ends of the rods are provided with sharp, upwardly extending prongs 33, 4B respectively. The outer end portions of the rods 34, 35 are secured to suitable actuating knobs 32, 44 carrying respective shanks at, 58. These two shanks are slidably receivable in the aforementioned bore 32, and the shank id is provided at the inner end thereof with a diametrically reduced extension or stem 58 which may abut the inner end of the'shank 46 and thus limit the extent to which the two shanks may be brought together in the bore 32. Moreover, it is to be noted that the compression spring 52, provided on the stem 50, is interposed between the inner ends of the shanks 45, 48, the purpose of this spring being to normally urge the shanks outwardly whereby, through the medium of the knobs 42, 44 and rods 34, 36 the prongs 38, 4B are urged into suitable recesses or receptacles 54 provided in the opposing surfaces of the aforementioned guides 26, as is best shown in Figure 4.

Finally, it is to be noted that an angle shaped member 56 is secured to the extension 24 adjacent the passage 28, this member terminating in a sharp tearing edge 58 which may, if desired, be provided with a row of sharp tearing teeth.

When the invention is placed in use, the roll of tape I4 is simply applied to the holder [2 as has already been described, the free end pordrawn from the dispenser, the required portion may be severed from the portion on the roll by bringing the tape in engagement with the tearing edge 58, in accordance with more-or-less conventional practice.

However, if it is desired to separate the tape longitudinally into two strips of equal width while it is being drawn from the roll, it is only necessary to depress the knob 42 so as to slide the associated shank 4E and the rod 34 inwardly in the extension 24, matters being so arrangedthat when the depressed knob 42 engages the adjacent of the guides 26, the-prong 38 is disposed centrally in the passage 23. Thereupon, the tape may be drawn from the roll, and at the same time, engage with the centrally disposed prong 38 whereby the tape will be longitudinally separated by the prong into two strips of equal width.

When it is desired to separate the tape into two strips of unequal width, namely, a strip onethird as wide and a strip two-thirds as wide as the tape on the roll, the knob 44 is depressed so that it contacts the adjacent of the guides 25. The rod 35 is shorter than the rod 34, and, mattors are so arranged that upon full depression of the knob 44, the prong 40 will separate the passage 28 into two lanes one twice as wide as the other, so that the tape drawn from theroll will be separated accordingly.

'When it is desired to separate the tape into three strips of equal width, it is only necessary to depress both knobs 42, 44 so that the knob 44 engages the adjacent guide 26 but the inner end of the shank 46 abuts the end of the stem 50 as indicated in Figure 4 and prevents the knob 42 from being depressed fully into engagement with the guide 26 adjacent thereto. Under such circumstances, the prongs 38, 49 will divide the passage 28 into three lanes of equal width, and as a result, the tape will be. separated into three strips of equal width, as will be clearly apparent.

In any event, after the tape has been separated into strips of the required length, the several strips may be torn or severed from the portion of the tape on the roll by means of the tearing edge 5-8, as has already been explained. It is to be noted, however, that inasmuch as the tearing edge 58 is disposed exteriorly with respect to the passage 28, the several strips of tape may be severed simultaneously in one operation.

Referring now to the modified embodiment of 4 i the invention illustrated in the accompanying Figures 5, 6 and 7, this embodiment is designated generally by the reference character 60 and is of a substantially simple construction consisting of an elongated holder 62 for a roll of tape 64, the end portions of the holder being provided with outwardly angulated extensions or brackets 66, 68 terminating in tearing edges 10, II.

The sides of the holder 62 are formed with inwardly extending slots 12 terminating at their inner ends in transverse portions 14 constituting seats for a pin or shaft (not shown) by which the roll of tape 64 may be rotatably mounted in the holder.

Alternatively, if the roll 64 is carried by a spool such as is indicated at 16, this spool may be rotatably supported by means of concentric depressions or steps 18 with which the sides of the housing 62 are provided, as is best shown in Figure .7. It should, of course, be understood that the housing 62 is formed from bendable, resilien materiahsuch as will permit the sides thereof to be spread apart in order to facilitate insertion and removal of the spool and roll of tape.

The extension 65 is provided with an upstanding prong 86, while two similar prongs 82 are provided on the extension 68'. These prongs are preferably struck out from the respective exten sions, and it is to benoted that the prong 8G is disposed centrally on the extension 66, separating the passage over this extension into two lanes of equal width. Similarly, the prongs 82 sepa rate the passage over the extension 63 into three equal lanes.

When the invention is placed in use, the tape may be drawn from the roll 54 and may be selectively engaged with the prong and with the prongs 82 so as to effect separation thereof into two or three strips of equal width, respectively, as will be clearly apparent. Moreover, tape may be dispensed without being separated, this being achieved by drawing the tape from the roll in such manner as not to engage any or" the separating prongs 8B, 82. The tape so drawn may be severed from the roll by the tearing edge H3, and since the prong 80 is disposed immediately adjacent this edge, only a small end portion of the tape remaining on the roll will be damaged by the prong while the severing operation is effected.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangelnent of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the claimed as new is:
