- the main frame section 11 is of a shell form comprising the left wall 11a of the housing, a slightly curved front wall 111;, a short back wall lie and bottom flanges forming front and back feet 11d and lie for the housing.
- the upper portion of the front wall 1115 forms a head structure 13 whereat the tape is cut as later described.
- the side cover 12 the same contour as the left wall lla and is notched at the bottom to receive lugs 14 and 15 extending laterally from the feet 11d and lie.

- the housing is open to the top between the side wall 11a and side cover 12 from the head structure 1'3 to the back wall 11c. Along the upper edges of the side wall 11a and cover 12 there are inwmdly curved rim flanges as shown. On viewing the housing from the side there appears a trough-like space 19 open to the sides just back of the head structure l3. This space provides access for the fingers to grip a length of double-coated tape -T leading from a supply roll R in the rearward portion of the housing to the head structure whereat the leading end is held releasably by adhesive contact.
- the supply roll R is mounted on a core 2t provided with peripheral cleats 21 for engaging the inside hole of the roll with a driving fit.
- the core has a shaft Z2 journalled in a bearing on the side wall 11a.
- a take-up reel 23 for the interliner I having a shaft 24 journa-lled also in a bearing on the side wall 11a.
- the reel has a large flange 23a at its inner side to space the interliner wound on the reel from the adjacent side wall 11a.
- the core of the reel has a slit 23b for receiving theend of the inter-liner and attaching the same thereto.
- the interliner is lead from the bottom of the supply roll around an idler roller 25 to the take-up reel, the roller 25 being journalled on a stud zo'staked to the side wall lla.
- the two pulleys are interconnected by a flexible V belt 29 trained past an idler roller 30 journalled on an arm 31 pivoted at 32 to the side wall Ila.
- the arm 31 is biased by a tension spring 33 to hold the belt taut.
- the ratio of the diameter of the drive pulley 27 to that of the driven pulley 23 is made greater than the ratio of the diameter of a full-sized supply roll R to the diameter of the core of the take-up reel 23. This is done so that the reel will tend always to be overdriven to wind up the interliner under sulficient tension to strip it from the supply roll throughout the entire unwinding of the latter. However, because of this overdriving of the reel a slippage in the drive coupling is necessary. This slippage is provided by a friction slip clutch 34 shown in exploded view in FIGURE 4.

- a friction disk 36 as of a cork compound
- a metal clutch disk 37 Applied fiat against the outer face of the pulley 27 is a friction disk 36 as of a cork compound, and applied next against the cork disk is a metal clutch disk 37.
- the portion of the hub 35 extending past the outer face of the pulley 27 has a fiat 35a and the clutch disk 37 has a corresponding non-circular center hole 37a so these two parts have a driving engagement.
- the shaft 22 has a threaded extension 22a.
- a clutch spring 38 is placed on this extension and compressed by a thumb screw 39 to the desired extent to obtain the necessary windup tension on the interliner at which slippage occurs.
- the belt coupling shown in FIGURE 3 is operative only when the supply roll is turned clockwise as it appears in this figure. The user is therefore required to load the dispenser so that the tape T will be drawn from the top of the supply roll. Also, for this same purpose the slit 23b in the take-up reel is adapted to grip the end of the interliner only when the take-up reel is turned in the same direction.
- the advantages in so loading the dispenser is that more finger space is provided in the trough 19 to grip the tape when the tape is lead from the top of the supply roll, and the points where the tape T and interliner I are stripped from the supply roll are so widely spaced as to prevent them from merging as successive lengths of tape are drawn from the supply roll.
- a serrated cutting member 40 for tear cutting lengths of tape drawn ahead of the head structure as the lengths are pulled sidewise against the serrated edge. After a length of tape has been so cut off the leading edge of the remaining length of tape T leading from the supply roll is held by adhesive contact with the top smooth surface of the cutting member 40 just back of its serrated edge.
- a special cutting mechanism comprising a razor blade 41 located in a wide transverse slot 42 in the head structure 13 so that the sharp upper edge of the blade is not exposed to present a hazard to the user.
- the blade is mounted at its ends in respective blocks 43 having narrow slits 44 open to the top to receive the blade.
- the blade has notches in its ends engaged by screws 45 threaded through the blocks from the front. To remove the blade the screws 45 are unthreaded until they are disengaged from the blade and then the user extends his fingernails into central openings 46 in the blocks and lifts the blade out of the slot 42.
- the cutting mechanism comprises further a blade lever 47 pivoted at 48 in the side wall 11a back of the trough 19.
- the lever has an inverted L shape and is biased into an upright position by a torsion spring 49 against an edge of the rim flange on the side wall.
- Riveted to opposite sides of the upper cross member of the blade lever are two blade members 5t? each in the form of a thin plate having its leading edge inclined in the direction of swinging movement which the blade members receive when the lever 47 is turned forwardly. These blade members are positioned to move into the cross slot 42 at opposite sides of the razor blade 41.
- the inclined leading edges of the blade members are not sharpened, and are preferably even rounded, so that they present no cutting hazard to the user.
- FIGURE 6 there is shown another form of cutting mechanism comprising simply a sharp cutting blade 51 mounted on a lever 52 corresponding to the lever 47 of the previous embodiment.
- lever 52 As lever 52 is swung forwardly the blade 52 cuts a tape held taut across the slot 42.
- the same is pivoted to the lever by providing it with oppositely extending lugs 51a which pivotally engage apertured ears 52a at opposite ends of the upper cross bar 52b of the lever, and further the lever is provided with an arm 52c at the far end of the cross bar which is parallel with the main arm of the lever.
- the blade normally hangs down by its own weight between the main arm of the lever and the side arm 52c to prevent accidental contact with the cutting edge.

- the blade reaches its dotted position shown in FIGURE 6 it begins to cut the tape as indicated because of the leading edge being inclined in the direction of swinging movement of the blade.
- the blade Upon release of the fingerpiece the blade is returned to its unoperated position.
- the drive coupling comprises a rocker arm 53 positioned for example at the back of the supply roll R and offset from the inner side thereof.
- the rocker is pivoted on a transverse stud 54 at its lower end to a housing frame 55 fractionally shown.
- lournalled at 56a to the upper end of the rocker arm is a drive roller 56 which extends crosswise of the supply roll and past the inner side thereof. Under influence of a tension spring 57 connected between the rocker and the frame the drive roller is pressed into driving engagement with the peripheral surface of the supply roll.
- the take-up reel 23 Iournalled on a transverse stud 58 rearwardly and downwardly from the drive roller 56 is the take-up reel 23.
- the reel is in line with the supply roll but has a driven wheel 59 secured to the inner end thereof which forms a drive train with the drive roller 56 and with in intermediate friction wheel 60.
- the wheel 60 is journ-alled at 61 to a link 62 which is pivoted at 63 to an arm 64- itself pivoted at its lower end to a stud 65 on the rocker 53.
- the link is biased by a tension spring 66 to pull the intermediate wheel into driving engagement with the drive roller 56 and the driven wheel 59.
- the drive roller and driven wheel may for example have metal peripheral surfaces and the intermediate wheel may be rubber tired.
- journal axis of the take-up reel must be spaced from the drive roller 56 and from the supply roll R at least by the radius of the largest size of interliner roll to be wound on the take-up reel.
- Another limitation on the drive train is that the driven wheel 59 be smaller in diameter than that of the take-up reel so that the reel will tend always to be overdriven at a faster peripheral speed than that of the supply roll.
- a friction slip means must be provided in the drive coupling. This slippage may occur between the drive roller 56 and the supply roll R or in the drive train itself.
- the tape T is stripped at 67 from the top of the roll R and the interliner I is stripped at 63 from a lower rearward part of the roll.
- the drive roller 56 engages the exposed adhesive side of the tape on the roll between these two stripping points and has a strong drive coupling with the roll even under a low biasing pressure of the rocker 53.
- this biasing pressure may be varied to set the winding tension on the interliner at which slippage will occur between the drive roller 56 and the supply roll R by providing anadjustable connection 69 between the biasing spring 57 and the rocker 53.
- the drive roller 56 may have a non-slip engagement with the supply poll and the bias pressure of the intermediate wheel 60 may be adjusted to set the winding tension on the interliner at which slippage will occur by providing an adjustable connection of the biasing spring 66 with the rocker 53.

West Grange, NJ. Filed Jan. 2'7, 1961, Ser. No. 85,319 Claims. (Cl. 22s-2s This invention relates to manual pull-oii dispensers for double-coated tapes.
The double-coated tapes comprise an intermediate layer or film of a paper, plastic or cloth coated on; both sides with pressure-sensitive adhesive. The tape is wound in roll form with a paper or cloth interliner treated so as to have poor adherence with the double-coated tape the supply roll to windup positively the int-a rliner.

FIGURE 8 is a top plan view of the dispenser shown in PKGURE 7.
The embodiment of double-coated tape dispenser shown in FIGURES 1-5 has a housing to of generally rectangular shape comprising a main frame section it and a removable side cover plate 12. The main frame section 11 is of a shell form comprising the left wall 11a of the housing, a slightly curved front wall 111;, a short back wall lie and bottom flanges forming front and back feet 11d and lie for the housing. The upper portion of the front wall 1115 forms a head structure 13 whereat the tape is cut as later described. The side cover 12 the same contour as the left wall lla and is notched at the bottom to receive lugs 14 and 15 extending laterally from the feet 11d and lie. The cover is secured removabl-y to the main section by a detachable hinge at its lower rearward portion comprising an inset downwardly extending lug 16 on the cover engaging a hole 17 in the foot file and by a thumbscrew 13 at its forward upper portion which threads into the front wall Mb. The housing is open to the top between the side wall 11a and side cover 12 from the head structure 1'3 to the back wall 11c. Along the upper edges of the side wall 11a and cover 12 there are inwmdly curved rim flanges as shown. On viewing the housing from the side there appears a trough-like space 19 open to the sides just back of the head structure l3. This space provides access for the fingers to grip a length of double-coated tape -T leading from a supply roll R in the rearward portion of the housing to the head structure whereat the leading end is held releasably by adhesive contact.
The supply roll R is mounted on a core 2t provided with peripheral cleats 21 for engaging the inside hole of the roll with a driving fit. The core has a shaft Z2 journalled in a bearing on the side wall 11a. In the forward lower portion of the housing is a take-up reel 23 for the interliner I having a shaft 24 journa-lled also in a bearing on the side wall 11a. The reel has a large flange 23a at its inner side to space the interliner wound on the reel from the adjacent side wall 11a. The core of the reel has a slit 23b for receiving theend of the inter-liner and attaching the same thereto. The interliner is lead from the bottom of the supply roll around an idler roller 25 to the take-up reel, the roller 25 being journalled on a stud zo'staked to the side wall lla. By so stripping the interliner at a point spaced nearly oppositely from that where the tape T is stripped from the 2 pulley 28 on an extension of the shaft 24. The two pulleys are interconnected by a flexible V belt 29 trained past an idler roller 30 journalled on an arm 31 pivoted at 32 to the side wall Ila. The arm 31 is biased by a tension spring 33 to hold the belt taut.
The ratio of the diameter of the drive pulley 27 to that of the driven pulley 23 is made greater than the ratio of the diameter of a full-sized supply roll R to the diameter of the core of the take-up reel 23. This is done so that the reel will tend always to be overdriven to wind up the interliner under sulficient tension to strip it from the supply roll throughout the entire unwinding of the latter. However, because of this overdriving of the reel a slippage in the drive coupling is necessary. This slippage is provided by a friction slip clutch 34 shown in exploded view in FIGURE 4. The clutch comprises the drive pulley 27 journalled freely on a flanged bushing 35 secured to the shaft 22. Applied fiat against the outer face of the pulley 27 is a friction disk 36 as of a cork compound, and applied next against the cork disk is a metal clutch disk 37. However, the portion of the hub 35 extending past the outer face of the pulley 27 has a fiat 35a and the clutch disk 37 has a corresponding non-circular center hole 37a so these two parts have a driving engagement. Beyond the hub 35 the shaft 22 has a threaded extension 22a. A clutch spring 38 is placed on this extension and compressed by a thumb screw 39 to the desired extent to obtain the necessary windup tension on the interliner at which slippage occurs.
The belt coupling shown in FIGURE 3 is operative only when the supply roll is turned clockwise as it appears in this figure. The user is therefore required to load the dispenser so that the tape T will be drawn from the top of the supply roll. Also, for this same purpose the slit 23b in the take-up reel is adapted to grip the end of the interliner only when the take-up reel is turned in the same direction. The advantages in so loading the dispenser is that more finger space is provided in the trough 19 to grip the tape when the tape is lead from the top of the supply roll, and the points where the tape T and interliner I are stripped from the supply roll are so widely spaced as to prevent them from merging as successive lengths of tape are drawn from the supply roll.
On the top surface of the head structure 13 along the front edge thereof is mounted a serrated cutting member 40 for tear cutting lengths of tape drawn ahead of the head structure as the lengths are pulled sidewise against the serrated edge. After a length of tape has been so cut off the leading edge of the remaining length of tape T leading from the supply roll is held by adhesive contact with the top smooth surface of the cutting member 40 just back of its serrated edge.
For the double-coated tapes which can not be tear cut such as those with a cloth intermediate layer there is provided a special cutting mechanism comprising a razor blade 41 located in a wide transverse slot 42 in the head structure 13 so that the sharp upper edge of the blade is not exposed to present a hazard to the user. The blade is mounted at its ends in respective blocks 43 having narrow slits 44 open to the top to receive the blade. The blade has notches in its ends engaged by screws 45 threaded through the blocks from the front. To remove the blade the screws 45 are unthreaded until they are disengaged from the blade and then the user extends his fingernails into central openings 46 in the blocks and lifts the blade out of the slot 42.
The cutting mechanism comprises further a blade lever 47 pivoted at 48 in the side wall 11a back of the trough 19. The lever has an inverted L shape and is biased into an upright position by a torsion spring 49 against an edge of the rim flange on the side wall. Riveted to opposite sides of the upper cross member of the blade lever are two blade members 5t? each in the form of a thin plate having its leading edge inclined in the direction of swinging movement which the blade members receive when the lever 47 is turned forwardly. These blade members are positioned to move into the cross slot 42 at opposite sides of the razor blade 41. The inclined leading edges of the blade members are not sharpened, and are preferably even rounded, so that they present no cutting hazard to the user. As the lade members are moved into the cross slot they press the tape across the head structure progressively along its width onto the sharp razor edge of the blade 41 to cut the same. When the user removes his hand from the lever 47 the latter is snapped back by the torsion spring 49 into its upper position leaving the leading portion of the tape T held by adhesive contact with the top surface of the head structure back of the slot 42 as shown in FIGURE 5.
In FIGURE 6 there is shown another form of cutting mechanism comprising simply a sharp cutting blade 51 mounted on a lever 52 corresponding to the lever 47 of the previous embodiment. As lever 52 is swung forwardly the blade 52 cuts a tape held taut across the slot 42. In order to protect the user from the sharp cutting edge of the blade the same is pivoted to the lever by providing it with oppositely extending lugs 51a which pivotally engage apertured ears 52a at opposite ends of the upper cross bar 52b of the lever, and further the lever is provided with an arm 52c at the far end of the cross bar which is parallel with the main arm of the lever. The blade normally hangs down by its own weight between the main arm of the lever and the side arm 52c to prevent accidental contact with the cutting edge. Extending rearwardly from the pivot axis of the blade 51 is a fingerpieee 51b. When the user presses against this I fingerpiece the blade is first turned upwardly until it is stopped by the cross member 5212 and is then swung forwardly into the cross slot 42 leading edge first. When the blade reaches its dotted position shown in FIGURE 6 it begins to cut the tape as indicated because of the leading edge being inclined in the direction of swinging movement of the blade. Upon release of the fingerpiece the blade is returned to its unoperated position.
In the embodiment of double-coated dispenser shown in FIGURES 7 and 8 the take-up reel is overdriven through a friction slip means directly by the supply roll R instead of from the supporting core 20. The drive coupling comprises a rocker arm 53 positioned for example at the back of the supply roll R and offset from the inner side thereof. The rocker is pivoted on a transverse stud 54 at its lower end to a housing frame 55 fractionally shown. lournalled at 56a to the upper end of the rocker arm is a drive roller 56 which extends crosswise of the supply roll and past the inner side thereof. Under influence of a tension spring 57 connected between the rocker and the frame the drive roller is pressed into driving engagement with the peripheral surface of the supply roll.
Iournalled on a transverse stud 58 rearwardly and downwardly from the drive roller 56 is the take-up reel 23. The reel is in line with the supply roll but has a driven wheel 59 secured to the inner end thereof which forms a drive train with the drive roller 56 and with in intermediate friction wheel 60. The wheel 60 is journ-alled at 61 to a link 62 which is pivoted at 63 to an arm 64- itself pivoted at its lower end to a stud 65 on the rocker 53. The link is biased by a tension spring 66 to pull the intermediate wheel into driving engagement with the drive roller 56 and the driven wheel 59. The drive roller and driven wheel may for example have metal peripheral surfaces and the intermediate wheel may be rubber tired.
In the drive coupling of FIGURES 7 and 8 the journal axis of the take-up reel must be spaced from the drive roller 56 and from the supply roll R at least by the radius of the largest size of interliner roll to be wound on the take-up reel. Another limitation on the drive train is that the driven wheel 59 be smaller in diameter than that of the take-up reel so that the reel will tend always to be overdriven at a faster peripheral speed than that of the supply roll.
Because of the overdriving tendency just mentioned a friction slip means must be provided in the drive coupling. This slippage may occur between the drive roller 56 and the supply roll R or in the drive train itself. In the particular illustrative embodiment of the invention herein shown the tape T is stripped at 67 from the top of the roll R and the interliner I is stripped at 63 from a lower rearward part of the roll. The drive roller 56 engages the exposed adhesive side of the tape on the roll between these two stripping points and has a strong drive coupling with the roll even under a low biasing pressure of the rocker 53. However, this biasing pressure may be varied to set the winding tension on the interliner at which slippage will occur between the drive roller 56 and the supply roll R by providing anadjustable connection 69 between the biasing spring 57 and the rocker 53. Alternatively, the drive roller 56 may have a non-slip engagement with the supply poll and the bias pressure of the intermediate wheel 60 may be adjusted to set the winding tension on the interliner at which slippage will occur by providing an adjustable connection of the biasing spring 66 with the rocker 53.
