11 Claims. (Cl. 164--84.5)

The present invention relates generally to tape dispensers. More particularly the invention relates to that type of dispenser which is expressly designed and adapted for use in handling a roll of tape of the variety that has an inner coating of permanently tacky or so-cal1ed pressure sensitive adhesive, and as its principal components or parts comprises: (l) a frame embodying a pair of parallel laterally spaced upstanding sides together with means for rotatably supporting the roll of tape between the sides; and (2) a platform which is located or positioned adjacent the sides of the frame and in alignment with the space between the frame sides and has adjacent its outer margin a cutting edge for cutting the tape into lengths as vit is unwound from the roll.

When it is desired in connection with use of a tape dispenser of this type to sever a length of tape from the roll the outer end of the tape is pulled outwards a distance corresponding to the length of tape that is desired and then the inner end of the pulled length is brought into adhesively connected relation with the platform and is severed by pulling it downwards so that it is cut by the cutting edge adjacent the outer margin of the platform. When it is desired again to cut a length from the roll the outer end of the tape is removed from the platform and then pulled outwards, the last mentioned operation being followed by the steps or operations heretofore described. In practice it has been found that the work or effort incident to manual strip ping or removal of the free or outer end of the tape from the platform each time a length of tape is severed from the roll renders use of the dispenser objectionable or diiicult.

The primary object of the instant invention is to provide a tape dispenser of the type under consideration which is an improvement upon, and eliminates the defects of, or objections to, previously designed dispensers and is characterized by the fact that it includes means whereby the free end of the tape is automatically stripped or pulled away from the platform at the conclusion of each tape severing operation to the end that it is f ree and hence may be readily gripped by the user of the dispenser in connection with the next following tape severing operation.

Another object of the invention is to provide a tape dispenser of the last mentioned character in which the means for automatically stripping the free or outer end of the tape from the platform at the conclusion of each tape severing Operation is essentially of simple vdesign and con- 2 struction and has associated with it a roller which is disposed adjacent the rear margin of the platform and serves to guide the tape over the platform as it is pulled from the roll in connection with a taper severing operation.

A further object of the invention is t0 provide a tape dispenser which is generally of new and improved construction, effectively and eiciently fulfills its intended purpose, and may be manufactured at a low and reasonable cost as well as operated with ease or facility.

Other objects of the invention and the various advantages and characteristics of the present tape dispenser will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof.

Figure '7 is a vertical longitudinal section of the dispenser of Figure 6; and

Figure 8 is a fragmentary vertical longitudinal section showing in detail the construction, arrangement and modey of operation of the automatic stripping means of the dispenser of Figure 6.

The dispenser which is shown in Figures l to 5, inclusive of the drawings constitutesone form or embodiment of the invention. It is expressly designed or adapted for use in handling or dis pensing a roll of tape I and as its principal or essential component parts comprises a frame I I, a platform I2, a guide roller I3 and means I@ for automatically stripping the tape from the platform I2 as described hereafter more in detail. The tape Ill is wound on a ring shaped core It and is of that type or Variety which has on its inner surface a coating of permanently tacky, pressure sensitive adhesive.

The frame I I serves to house and also rotatably to support the roll of tape and comprises a bottom wall I6, a pair of parallel laterally spaced upstanding sides I1 and an upstanding front wall I3. It is preferably in the form of a one-piece casting in order that it is rigid. The sides II are jointed to, and project upwards from, the side margins of the bottom wall I6 and are spaced apart a distance slightly in excess of the width of the tape Il). They are adapted and designed to lap the sides of the roll ,of tape as best shown in Figures 1, 2 and 3 and have in the rear portions of the inner faces thereof opposed upwardly and rearwardly inclined grooves I9, the lower ends of which terminate adjacent the upper portions of the sides and form seats for supporting the ends of a horizontally extending spindle 2G. The latter extends through the core I5 and functions rotatably to support the roll of tape Iii. The upper ends of the grooves I9 are open in order that the spindle may be removed from the frame when it is desired to apply a new roll of tape to the spindle. In mounting the roll of tape on the frame the spindle 2E! is first inserted through the core I5. Thereafter the ends of the spindle are brought into alignment with the upper ends of the grooves I9 and the spindle together with the roll is lowered until the ends of the spindle seat in the lower ends of the grooves, To remove the spindle it is only necessary to slide the latter upwards out of the two grooves. The front wall I8 of the frame I I is joined to, and extends across the front margins of, the sides Il. The upper margin of the front wall and the upper margins of the frame sides are coplanar.

The platform I 2 is located adjacent the upper end of the front wall I8 of the frame II and extends substantially horizontally. It is formed of any suitable metal and has the rear or inner margin thereof bent downwards at right angles t0 form a depending flange ZI' which nts against the upper portion of the rear face of the front wall I8 and is secured in place by way of bolts 2'2. The latter extend through holes 23 in the ange 2l and iit within threaded sockets 24 in the upper portion of said front wall I8. The front or outer margin of the platform I2 is shaped to form a cutting edge 25 for severing the tape I l into lengths or strips. When it is desired to sever a length of tape from the roll the free or outer end of the tape is pulled outwards a distance corresponding to the length of tape that is desired and then the inner end of the pulled length is brought into adhesively connected relation with the platform and is severed by the cutting edge 25. Severance or cutting of the pulled length is effected by exerting downward `pressure on the length so as to cause the edge 25 to cut through the inner end of the length. If desired, the cutting edge 25 may be in the form of a rectilinear series of V-shaped teeth as shown in Figures 1 and 2 of the drawings. In connection with severing of a length of the tape by the cutting edge 25 the portion ofthe tape that is directly inwards of the cutting edgeis brought into adhesively connected relation with the top surface of the platform l2 as the pulled length of the tape is cut by the cutting edge 25. Preferably the platform I2 is iiat and rests directly on the upper or top edge of the front wall I8 of the dispenser frame II.

The guide roller I3 extends horizontally and is disposed between the front upper corners of the frame sides Il. It is mounted for free rotation on a shaft '26 which extends through a centrally disposed longitudinally extending open ended bore 2l in the roller I3 and has its ends mounted in aligned holes 28 in the front upper corners of the frame sides I'I. vAs shown in the drawings the shaft 26 is so positioned that the upper portion of the guide roller I3 is located a slight distance above the upper surface of the platform I2. When the tape Ill is pulled forwards from the roll in connection with a severing or cutting operation the tape as itis pulled from the roll rides over and effects rotation of the guide roller I3. Rotation of the guide roller is occasioned by the fact that the roller is gripped by the adhesive on the inner face of the tape. The guide roller in connection with a tape pulling operation preparatory to severing a length of tape from the roll serves to guide the pulled tape over the platform I 2. Because the upper portion of the guide roller is'positioned a slight distance above the upper surface of the platform only a comparatively small portion of the outer end of the tape is adhesively connected to the platform after severing a length by the cutting edge 25.

The means I4 for automatically stripping the free or outer end of the tape from the platform I2 after` severance of a length of the tape by the cutting edge 25 is in the form of a supplemental ro'ler 29. This roller extends horizontally and is located directly behind the guide roller I3. It is vertically movable as shown in Figures 3, 4 and 5 and has as supporting means therefor a shaft 3Q. The latter extends through a centrally disposed longitudinally extending open ended bore 3| in the roller 29 and has its ends mounted in a pair of aligned vertically extendingeslots 32 in a pair of upstanding ears 33. Such ears are formed integraly with the front portions of the upper margins of the frame sides I'I. The slots 32 permit the supplemental roller 29 to move down and up between a down position wherein it is disposed directly adjacent and in horizontal alignment with` the guide roller I3 (see Figure 5) and an up position wherein it is disposed above the guide roller (see Figures 3 and 4). When the tape is pulled forwards preparatory to severing a length from the roll the supplemental roler 29, due to the tape becoming taut, is shifted upwards into its up position. In such position the supplemental roller 29 rolls or revolves freely as the tape is pulled from the roll. After the pulled length of the tape is severed by the out` ting edge as hereinbefore described, the supV plemental roller, due to its weight andthe action of gravity, moves downwards into its down posh' tion. In connection with initial downward' shift of the supplemental roller into its down position the free end of the tape which in connection with a tape severing operation is brought into adhesively connected relation with the platform t2 is caused to be withdrawn out of adhesively connected relation with the platform. In con nection with further and complete downward shift of the supplemental roller the portion of the outer end of the tape that is between the supplemental roller and the guide roller is swung upwards with the result that thel outer extremity of the outer end of the tape is swung upwardsr into a position wherein it is completely free from therplatform and is in readiness to be gripped by the user of the dispenser in connection with the. next following or succeeding tape severing operation. During the last part of down shift of the supplemental roller into its down position the guide roller i3 is caused to rotate in a countercl'ockwse direction as viewed in Figures 1 to 5 and forms a central fulcrum whereby the free or outer end of the tape is caused to swing upwards away from the platform l2'. A leaf spring 34 is mounted on the bottom wall it. of the dispenser frame i! and is applied to the rollV of tape so that it places a drag thereon tending to retard rotation of the roll with respect to the frame. One end of this leaf spring is anchored or attached to the central portion of the upper face of the frame bottom wall by way of a rivet 35'. The other end of the leaf spring is free and bears against the bottom portion of the tape roll. The leaf spring is arranged so that it extends lengthwise of the frame and causes the free end thereof to engage the bottom portion of the roll with upward pressure. The suppemental roller 29 is preferably formed of comparatively heavy metalv in order that it is capable in response to its weight and the action of gravity automatically to strip the free end of the tape from the platform l2 after a tape severing operation.

When it is desired to sever a length of tape t' from the roller the free or outer end of the tape is gripped and then pulled forwards a distance corresponding to the length of tape that is desired. In connection with forward pulling of the tape the supplemental roller 29 moves bodily upwards into its up position, as previouslyy pointed out, and the tape is guided over the platform i2 by the guide roller i3. After the desired length of tape has been pulled from the rolf the length is severed by urging it downwards so, as. to, effect cutting thereof by the cutting edge 25. As soon as the length of tape is severed and resultantly' there is nor longer a forward pull on the remain-- ing tape the supplemental roller 29, due to. its weight and the action of gravity, moves. bodily downwards, into its down position. During suicl movement the free or outer end of the tape is stripped from the platform and isy swung upwards as heretofore pointed out. By reason of the fact that the free end of the tape is stripped.- from the patform andY swung upwards away from. the latter at the conclusion of each tape cutting. oper ation it is automatically so positioned that it is in readiness readily to be gripped in connection with the succeeding or next ensuing tape severing operation.

The tape. dispenser which is shownV in Figures 6 1 to 5, inclusive, may be operated with ease or facility because of the fact that it includes the supplemental roller 29' whereby the free end of the tape is automatically stripped or pulled away from the.A platform l2v at the conclusion of each tape severing operation. It is essentially simple in construction and hence may be produced at a low-and reasonable cost.

The dispenser which is shown in Figures 6 to 8', inclusive of the drawings constitutes another orv modified embodiment of the invention. It is adapted to dispense, a roll 0f tape 10a having on. its innerA surface a coating of permanently tacky pressure sensitive adhesive and comprises as its principal parts a frame Ila, a platform I2a, a, guide roller I'Sa and means Ma for automatically stripping the, outer or free end of the tape from the platform [2a at the conclusion of each tapesevering operation. The frame lla, the platform I'Za and the guide roller 13a are constructed similarly to, and. serve the same purpose as, the corresponding parts of the dispenser of Figures 1 to 5, inclusive; The platform l2@ is mounted on the upper end of the front wall of the frame ila and embodies at its front or outer margin a cutting edge 25a. The guide roller I3a is located a small distance behind the platform 12a and is mounted for free rotary motion on a shaft 25a, The latter is so supported that the upper portion of the guide roller is disposed a slight distance` above the upper surface of the platform 12a.

The automatic stripping means la serves the same purpose as, but functions and is constructed .1 differently than, the automatic stripping means t4. of the dispenser of Figures l to 5, inclusive. It is associated and coacts with the guide roller i3d behind the platform 12a, and comprises a U- shaped member 36. The latter consists of a crosspiece 3l and a pair of side pieces 38 and 39. The crosspiece 3l' of the U-shaped member 36 is flat as best shown in Figure '7, and is mounted on, and carried by, the side pieces 38 and 39 so that it is` freeLto swing back and forth between a down position wherein the outer marginal portion thereof' overliesl and extends lengthwise of the rear margin of the platform 12a (see Figure 7) and an up positionY wherein it is disposed upwards and rearwards of the platform, as shown in Figure 8. The side pieces 38 and 39 of the U- shaped member 36 are connected to, and project rearwards from, the ends of the crosspieoe 31 and have at the rear ends thereof holes through which the ends of the shaft 26a extend loosely. The shaft supports the U-shaped member 36 so that it is free; to swing vertically in order to bring the erosspiece. 31 into its down and up positions. The Ll-shaped member is urged upwards by way of an arm 4,0 and a spiral tension spring 4i. The arm 4i!- is connected rigidly to, and projects rearwards from, the rear end of the side piece 38 and is located adjacent the inner face of one of the upstanding sides of the dispenser frame l la. The spring 4I extends vertically and is disposed between the frame sides. The upper end of the,v spring is anchored to the rear end of the arm 4l]` and the lower end of the spring is connected t0. a pin 42., The spring is so loaded and applied that it urges the U-shaped member 36 upwards away rom the platform I2a. A pin 43 underlies the arm 40, and coacts therewith to limit upward swinging of the Ul-shaped member 35. Such pin is xedly connected to, and projects inwards from-, the frame side wal-l adjacent which the arm dill-is disposed.

` When the free end of the tape is pulled forwards in connection with a cutting or severing of a length from the roll Ia the pulled length rides over and is guided by the guide roller 13a and swings the U-shaped member 36 into its down position against the force of the tension spring 4l, as shown in Figure 7. In connection with initial or partial cutting of the length by the cutting edge 25a the portion of the tape that is directly inwards of the cutting edge is caused to adhere to the front margin of the platform I2a. As soon as the cutting operation is completed and the tension on the free connected end of the tape is thereby released the U-shaped member 36 swings upwards in response to the action or force of the tension spring di and thus causes the free end of the tape to be stripped or freed from the platform 12a. In view of the fact that the crosspiece 31 of the U-shaped member is disposed an appreciable distance rearwards of the cutting edge 25a the outer extremity of the free end of the tape is exposed after the automatic stripping operation and hence may be readily gripped by the user of the dispenser in connection with the next following tape severing operation. In connection with upward swing of the U-shaped member the portion of the free end of the tape that is inwards of the outer end extremity fulcrums about the guide roller 26a by reason of the fact that such portion is in adhesively connected relation with the guide roller. When the free end of the tape is pulled outwards in connection with the next following or succeeding tape severing operation initial pull on the tape results in disengagement or disconnection of the crosspiece 37 of the U-shaped member 36 from the adhesive coating on the adjacent or inner surface of the tape. It is contemplated that during outward pulling of the tape the tape will at all times ride over the guide roller |3a and the portion of the tape that is in direct contact with the roller will be adhesively connected to the roller.

The tape dispenser of Figures 6 to 8, inclusive, of the drawings differs from that of Figures 1 to 5, inclusive, in that the automatic stripping means is applied to the free end of the tape at a point between the platform and the guide roller and urges the adjacent portion of the tape upwards. In the tape dispenser of Figures 1 to 5, inclusive, the automatic stripping means, instead of being so applied is applied at a point behind the guide roller and urges the tape downwards. Both automatic stripping means, however, serve the same purpose in that each operates automatically to disengage the free end of the tape from the platform directly after severance of a length of the tape by the cutting edge on the front portion of the platform. The tape dispenser of Figures 6 to 8, like that of Figures 1 to 5, is essentially simple in design and may be used with extreme facility because it includes the automatic stripping means Illa.

The invention is not to be understood as restricted to the details set forth since these may be modied within the scope of the appended claims without departing from the spirit and scope of the invention.
