ADHESIVE TAPE DISPENSING AND SEVERING CLIP Filed April 2, 1948 WIIIIIIIIIIIIIIIIJ V a: man 1| f/VVE/V 70/? BMJQL M M Patented Oct. 3, 1950 UNITED STATES PATENT OFFICE ADHESIVE TAPE DISPENSING AND SEVERING CLIP Burton H. Locke, Framingham, Mass. Application April 2, 1948, Serial No. 18,553
2 Claims. 1
My invention relates to improvements in clips for use in dispensing and severing tape from a roll, especially pressure-sensitive coated tape, 1. e., tape which is normally tacky without the aid of heat or solvents and can be applied to objects by pressure or normal contact therewith.
Heretofore, in cases wherein a dispenser is not afforded to handle pressure-sensitive adhesive tape, a knife or shears, or the like, have been relied upon for severing the tape from its roll and generally a knife or other thin bladed instrument has been required to raise the end of the tape from its adhesion to the roll prior to dispensing the tape therefrom. The objects of this invention are to eliminate such requirements by the provision of a simple and inexpensive device that can be applied to conventional rolls of such tape.
The main object is to provide a simple means that will function to retain the free end of the tape from contact with the roll at all times and thereby eliminate the laborous task of detaching and raising the said end of the tape each time a portion of tape is dispensed, or pulled, from the roll, and also to function to swing a severing blade around the roll of tape adjacent to the path in which the tape is released from the roll in the dispensing thereof so that the said blade is always conveniently at hand for use in severing the tape from the roll after it is dispensed.
Those familiar with the art are aware that it is diflicult to raise the end of pressure-sensitive adhesive tape from its roll for grasping, as required to dispense the tape, after it is once allowed to adhere thereto, which normally takes place whenever the free end is released after severing. In fact, it is generally diflicult to even locate the end of the tape on the roll the adhesion is so tight.
I conceive to provide a rotatable means to contact the coated side of the tape and be carried radially around the roll of tape by rolling on the tape in normal adherence therewith as the tape is radially detached from its roll in the normal dispensing thereof. The said rotatable is thereby rolled to proper position on the tape to serve in preventing the end of the tape, that becomes freed by the severing of the dispensed portion of tape, from contacting the roll of tape and becoming adhered thereto.
Another object is to provide a means for conveniently severing the tape from its roll after it is dispensed therefrom. To accomplish this objective, I conceive to provide a severing means that will be carried around the roll of tape with the tape contacting means so that the said severing means will always be positioned near to the point of detachment of the tape from its roll strip.
In the accompanying drawing:
Figure 1 is a side view of a conventional roll of tape with my dispensing and severing clip applied thereto.
Figure 2 is a section 2-2 of Figure 1.
Figure 3 is front view of another construction for thearm structure.
The drawing shows my adhesive tape dispens-.
ing and severing clip in the simplest conceivable form to permitits being produced inexpensively and, therefore, aiforded with each roll of tape and thrown away with the core of the roll after' thetape has been used. However, it is conceivable that more elaborate structures, which go to make a more attractive and permanent product:
involving the present if desired.
In Figures 1 and 2,my device is shown applied to one type of conventional roll of pressuresensitive coated adhesive tape Ill, known in the invention could be produced tradeas Scotch tape, having a core I l on which the tape is wound, and caps I 2 that abut the end of the core and extend a short distance inside of the same for support. My device comprises a radially pivoted arm structure I3 which, in this instance, bridges the roll of tape ID at the outer end M, of said structure, and extends down each side of the roll of tape with inwardly extending end portions l5 that extend loosely through openings [6, provided concentrically in each end cap i2. Thus arm structure It is pivotally mounted to swing around the roll of tape it) as required. Arm structure [3 is most easily adaptable to be constructed of round bar or wire material, as shown, and the outer end l4, thereof, is flattened andpointed and generally serrated to form a suitable edge on which to sever the tape from the roll. .1 Arm structure I3 is of suitable resilient structure so that the arm portions can be readily sprung apart sufiiciently to permit passing over the roll of tape Ill and then being inserted into the opening in each end cap l2.
There is a roll l1, generally having a smooth hard surface to contact the coated side of the tape, loosely mounted on a rod or bar l8 which is either formed integral with or attached to arm structure l3 in some conventional manner, such as soldering, welding or brazing thereto, intermediate the outer end I4, thereof, and the roll of tape. As shown, the opening I9, which is provided in roll H, is generally relatively larger than bar Hi to insure free movement of said roll and to permit the same to be lifted free of the roll of tape as the tape is being dispensed, such as shown in dotted or broken lines at B, so as to eliminate interference of the roll IT with the tape, and thus eliminate binding of the tape under roll 11, as the tape is dispensed, or pulled, from the roll, especially when the roll of tape is of its maximum size. Also, when the device is at rest, as shown as A, the roll I! can rest on the roll of tape due to the enlarged opening in the said roll relative to the supporting bar l8.
The device is arranged on the roll of tape so that the roll contacts the coated side 20 of the tape and when a portion of tape has been severed from the roll and the device is at rest the tape is left adhered to the roll ll, as shown at A, with the free end 2| of the tape extending upward in convenient position to grasp in dispensing another portion of tape.
Whenever the extreme free end of the tape adheres to the severing blade and cannot be grasped, the same can be released therefrom by a slight manipulated movement of the arm structure, clockwise in this instance, which will cause roll I? to rotate, also clockwise, and thereby pull the tape from the severing blade.
A novel construction for the arm I3 is shown by Figure 3 wherein the complete structure is formed from one continuous piece of rod or wire and which includes the forming of a relatively short projection 22 on the adjacent sides of the arm structures to support the roll ll by projecting into the ends of said roll, respectively. This construction eliminates the necessity of attaching the'continuous bar It between the arm structures to support the roll H and permits the said roll being inserted or removed from the arm structure by the spreading of the arms, such as is required in attaching the structure onto the roll of tape or detaching the same therefrom.
In operation, the roll of tape is loosely held between the thumb and forefinger of one hand, to permit rotation of the same therebetween, as the tape is dispensed, or pulled, from its roll by the thumb and forefinger of the other hand. The dispensing of the tape causes the roll H to rotate in the direction of the arrow C and thereby roll along the tape and also to be carried around the roll of tape adjacent to where the tape is being detached from its roll by the tape being pulled radially from the same, as shown at C. The tape normally adheres slightly around the periphcry of roll ll, as best shown by the dotted lines representing the structure when the tape has been dispensed to the position C. Due to the normal tight adhering of pressure-sensitive adhesive tape to surfaces coming into contact with it, the tape will not detach from roll i! when pulled from its roll, but rather will cause roll [1 to rotate and thereby travel along the tape which will cause the arm structure H o swing clockwise around the roll of tape in accordance with the radial travel of the dispensing tape therearound. Therefore, the severing blade M will be carried around the roll of tape adjacent to the dispensing of the tape from its roll and thus will always be at hand in convenient position for use in severing the dispensed portion of tape from its roll. Also, roll ll will always be adjacent to the severing blade to prevent the freed end of the tape from dropping into adherence with its roll and will retain said end of tape in convenient position for grasping for subsequent dispensing of tape.
It seems obvious that the most effective shape for the periphery of roll I! is annular, as shown, however, the said peripher could be oval; hexagonal, or of any other shape suitable to be rotated by the movement of the tape through the medium of normal adhesion therewith, without departing from the invention.
Also, it is obvious that the novel features set forth could be incorporated in various structures suitable to be adapted to various styles of rolls of pressure-sensitive coated adhesive tape as long as the structure is such as to carry the tape contacting means and the tape severing means substantially concentric with the roll of tape.
Therefore, I do not wish to be confined to the exact details set forth in so far as the same are susceptible of modification without departing from the spirit or scope of the invention.
1. An adhesive tape dispensing and severing clip comprising a U-shaped member, means at the open end of the said member adapted to pivo'tally mount it substantially concentric to a roll of pressure-sensitive adhesive tape, a severing blade on the closed end portion of said member for severing the tape thereon, and a roller rotatively and loosely mounted on said member parallel to and intermediate the severing blade and the roll of tape for limited movement toward and away from said blade whereby to contact the coated side of the tape and, by reason of the pressure-sensitive adhesion of the tape to said roller, to travel along the tape as the tape is dispensed and to be carried radiall around the roll of tape in accordance with the radial dispensing of the tape therefrom to swing said arm structure to operatively position said severing blade.
2. In combination, a roll of pressure-sensitive adhesive tape and a dispensing device as described in claim 1 mounted thereon.
