holder anddispenser for rolls of pressure+sensitive-plastic tape wherein the free end of the tape is. maintained out of contact with the stored roll and is readily available for dispensing.

A further object pf the invention is the. provision of a holder and dispenser for pressurersensit ve tape,.of the plastic type, wherein a novel type of severing .rneans; is provided to readily sev'er thetape when the required v.amount has been pulled from the rolLj.

Pressure-sensitive tapes, of many types, have found a wide field of usefulness today both in the commercial field and around the average home.

It is with one of these popular types of tapes that this invention is primarily concerned, namely, a tough plastic tape known as electricians tape. While this tape is commonly known as electricians tape, its use is by no means restricted to electricians since it has many fields of application both in industry and by the average home owner. One of the outstanding characteristics of this type of tape is the tenacity with which it adheres to itself when wrapped around to embrace a joint or the like. Since this tape has a strong afiinity for itself, it is somewhat difiicult to remove it from the roll and due to its toughness it cannot readily be severed by a quick snap or tear as is possible with other types of tape, but must be severed with a sharp instrument.

Having knowledge. of the various types of holders and dispensers available for pressure-sensitive tapes and realizing that they are not suitable for tough plastic tape, I have devised a structure which not only facilitates the removal of the tape from the roll, but provides a means for readily severing the tape witha minimum amount of effort. The severing means which forms part of this invention is an integral part of the dispenser and is so constructed that no hazard is presented to'the user either during the dispensing of the tape or when the dispenser is not in use.

In the preferred embodiment of my invention, the structure comprises essentially a pair of longitudinally extending spaced apart parallel side members joined together to provide a substantially inverted U-shaped structure. The free ends of the frame terminate in flat disclike opposed surfaces and have spaced therebetween a member for rotatably supporting a roll of tape.

Located adjacent the return bend portions of the frame, or bridge, which joins the side members, are suitable guide rollers between which the tape passes as it is drawn from the roll.

Positioned on the bridge portion of the frame, at the top thereof, is a knife blade which is triangular in configuration and which is provided with suitable guard members which are integral with the side members of the frame. Thus, as the tape is drawn from the roll, it passes between the two guide rollers and is pulled up- 3,007,619 Patented Nov. 7, 1961 'ice ward against the triangular blade between the spaced apart ears thereby severing the tape and permitting the free end of the tape on the roll to be maintained in a position out of contact with the roll.

The invention will be more clearly understood from the following detailed description when read in connection with the accompanying drawing, in which:

FIG. 1 is a side elevational view of the device of my invention with the tape extending therefrom shown in dot and dash lines and shows the position thatthe tape .as sm les as it is forced against the cutting blade;

*FIG. 2 is a top plan view of FIG. 1 and illustrates in detail the shape and position of the cutting blade;

"FIG. 3 is a fragmentary sectional view taken on line of FIG. 1; and

FIG. :4 is a perspective view of the device shown in FIG. .1 and illustrates the manner in which the tape leaves the roll, is forced between the guard members and against ,the cutting blade. 20

As shown in-the various figures and with particular reference to FIGS. 1, 2 and 4, the device of my invention comprises a body member of inverted U-shaped .con-

figuration, preferably fabricated from metal, having oppositely disposed spaced apart parallel legs 11 and 11 extending from a substantially fiat bridge portion 12. The

legs 10 and 11 are preferably flat, have a tapered con- .figuration and terminate in flat, enlarged disc-

shaped portions

13 and 14.

Centrally disposed with respect to the

disc portions

13 and 14 and secured thereto by means of the knurled screw 15 and the nut 16 is a removable axle member 17. Rotatably mounted on the axle member 17 and confined between the

disc portions

13 and 14, is the roll of pressure-sensitive tape TP.

Journaled between the legs 10 and 11 as shown in FIGS. 1 and 4 and in spaced relation with each other and with the roll of tape TP, are the

guide rollers

18 and 19. Located in alignment with the roller 19 and integral with the legs 10 and 11 are the extending

ear portions

20 and 21. These ears bridge the two legs and serve as a guard means for preventing the free end of the tape TP from coming into contact with the roll of tape during the removal of the tape from the roll, and the subsequent severing operation.

Located on the bridge portion 12 and protected by a second guard means which comprises the arcuate-shaped

integral ears

22 and 23, is the cutting blade 24. This cutting blade 24 is triangular in configuration, has a slight downward bend at its point and is secured to the bridge portion 12 by means of the screw 25. The cutting edges of the blade 24 are at an angle of approximately 45 degrees with respect to the perpendicular and are sharply ground to provide a keen cutting edge.

As shown in FIG. 4 an extending apertured car 26 is provided for the securing of a suitable lanyard 27 thereto by means of the snap hook 28.

In dispensing tape from my improved device, the end 29 of the tape TP, which has been initially threaded between the

rollers

18 and 19, is pulled outwardly over the

guide ears

20 and 21 to the desired length. The exposed length of tape is then drawn upward, forced between the

cars

22 and 23, against the blade 24. Continued tension on the tape causes the end of the blade 24 to puncture the tape and due to the novel configuration of the blade 24, two cuts are made, each cut starting at the puncture and continuing tothe outer edge of the tape thereby readily severing the tape with little effort on the part of the user.

Due to the novel structure of the device of this invention, the free end of the tape on the roll is maintained out of contact with itself and is readily available for further dispensing. The novel structure of the knife ,24, together with the novel structure of the

guide ears

22 and 23, provides a means for safely and efiiciently severing the tough plastic tape intended for use with this device.

It is understood that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
