No. 545,026 Claims priority, application Great Britain, Apr. 29, 1965, 18,000/65 17 Claims. (Cl. 225-16) This invention relates to dispensing devices for adhesive tape.

Various forms of devices for dispensing pressure sensitive adhesive tape have been proposed. For example one such device comprises mounting means for supporting a roll of adhesive tape so that it is rotatable about its axis and a cutting edge whereby the tape can be severed and which also may serve to support the end of the adhesive tape remaining after a severing operation. In using such a device the end of the tape is held by hand and withdrawn to unwind the required length of tape from the roll. The tape is then severed on the cutting edge and the length of tape dispensed can be applied manually to an article, it usually being necessary to hold the tape at both ends in this last connection.

In another known device a roll of adhesive tape is similarly rotatably supported and is enclosed in a casing having a slot through which the tape can be withdrawn. A cutting edge is also provided near the slot and this type of dispensing device can either be used in the manner described above by withdrawing a length of tape, severing it and then applying it to an article, or by applying the short length of adhesive tape extending from the slot directly to an article, withdrawing the required length of tape from the roll and then severing the tape by altering the angle of application of the dispensing device. Even when this latter method of use of the device is employed, however, it is usually found to be necessary to employ some direct manual gripping contact with the tape since the tape tends to adhere to the bounding walls of the slot and then has to be freed manually. Moreover the tension applied to the tape in withdrawing further tape from the roll is great and if only the very short length of tape which is normally extending from the slot is applied to an article it is frequently found that the article cannot withstand the pressure that must be applied to it by the dispenser in order to ensure that said short length of tape adheres sutiiciently firmly to withstand the aforesaid tension and also the friction at the application point of the tape. Hence it is frequently found to be necessary to withdraw a longer length of tape manually from the dispensing device before applying it to the article and withdrawing, by applying pressure to the device itself, the remaining required length of tape.

Thus with such devices it is found that manual contact with the adhesive tape being dispensed is usually necessary and such contact is undesirable due to the moisture and dirt transmitted to it by such contact, which may impair its adhesive properties, and due to the ditliculty in controlling such tape manually, for example in applying a length of it to an article, which may lead to waste.

It is an object of this invention to provide an improved dispensing device for adhesive tape whereby the disadvantages indicated above of previously proposed such devices may be alleviated.

According to the invention there is provided a dispensing device for adhesive tape comprising means for rotatably supporting a roll of adhesive tape, a slide surface for the non-adhesive side of a length of tape, a slide surface for the non-adhesive side of a length of tape, from said roll, tape displacing means, actuating means coupled to said displacing means for displacing said displacing means 3,386,534 Patented June 4, 1968 in first and second opposite directions and whereby said displacing means is urged towards said slide surface when being displaced in said first direction to enable said dispensing means to engage and withdraw tape from said roll along said slide surface, and whereby said displacing means is removed from said slide surface when being displaced in said second direction, and unidirectional restraining means for the tape such that tape can be drawn past said restraining means during movement of said displacing means in said first direction, but which holds said tape in its moved position during movement of said displacing means in said second direction.

Preferably said displacing means comprises two displacing members for the tape, one on each side of the restraining means and both coupled to said actuating means.

In accordance with an embodiment of the invention said dispensing device incorporates two piercing and cutting members for severing adhesive tape, further actuating means coupled to said piercing and cutting members for moving said members into the path of adhesive tape supported on said slide surface, and whereby said piercing and cutting members are close together when moved into said path so that tape held under tension is pierced by said members at a position intermediate of its width, and said piercing and cutting members are moved apart whilst in said path so that pierced tape is severed across its width by said members.

It has been found that by employing a cutting edge of conventional type to sever the tape frequently the tape adheres to the edge and moreover it is necessary to apply a force to the tape in order to sever it which may be undesirably large. It has been proposed to employ cutting blades which perform a scissors action and cut the tape across its width, but it has been found that when such an action is employed frequently one of the blades becomes attached to the adhesive side of the tape, which has to be removed. By piercing the tape at a position intermediate of its width and then cutting across said width from said pierced position the problem of the adhesive side of the tape becoming attached to the cutting members can be greatly reduced.

In order that the invention may be clearly understood and readily carried into etfect it will now be more fully described with reference to the accompanying drawings, in which:

FIGURE 1 is a section through an adhesive tape dispensing device according to one embodiment of the invention,

FIGURE 2 is a part sectional fragmentary view of the device of FIGURE 1, on an enlarged scale,

FIGURE 3 is a sectional view taken along the line III-III of FIGURE 2,

FIGURE 4 is a top elevation of a part of a tape dispensing device according to a modified embodiment of the invention,

FIGURE 5 is a side elevation of part of the device of FIGURE 4, and

FIGURE 6 represents a part modification to the embodiment of FIGURE 1.

In the embodiment illustrated in FIGURES l to 3 the device comprises a pair of spaced parallel side plates 1, the nearside plate 1 having been omitted in FIGURES 1 and 2 to show the parts of the device mounted between the plates 1. The two plates 1 are held in their spaced parallel relationship by means of suitable coupling members, for example incorporating rivets. Each plate 1 comprises a spool holder portion 1a, a body portion 1b and a hand grip portion 1c as shown in FIGURE 1. Mounted between the upper extremities, as viewed in the drawings, of the body portions 1b of plates 1 is an arm 2 predominantly of H-section, having parallel side members 2a joined by a web 212 which constitutes a slide surface for the tape to be dispensed. The arm 2 is rigidly coupled to the body portions 1b of the plates 1 in this embodiment by means of rivets 1e, some of which are visible in FIG- URES 1 and 2. As can be seen most clearly in FIGURE 1, the arm 2 extends substantially from the spool holder portion 1a to beyond the remote end of the body portion 1b and the projecting end of said arm 2 is tapered as indicated in FIGURE 1. In this embodiment, the lowermost portions of the side members 2a are removed at said tapered end, and a corresponding portion 20 of the Web 2!) is curved upwardly and tapered to form a cutting edge 2:! at its extremity. A further part of the lowermost portions of each of the side members 2a, namely that part which in FIGURES 1 and 2 is indicated between the

lines

22, 2e, is also removed and the slot thereby formed accommodates a shoe 13 of U-section having its base 131) in slidable contact with the web 212, slidable movement of the shoe 13 with respect to said web 21) being permitted within the confines of the slot formed between the

lines

22, 2e. The U-shaped configuration of the shoe 13 is most clearly visible in FIGURE 3, and the side arms of this shoe are indicated by reference 13a in all FIGURES 1 to 3. As can be seen in FIGURES 1 and 2 the side arms 13a have corresponding inclined slots 13c for accommodating a pin 6a. As will become apparent hereinafter the pin 6a forms a displacing member for the tape being dispensed.

A finger 6 of rectangular cross section, as can be seen most clearly in FIGURE 3, is disposed with its narrower cross sectional dimension across the space between the side plates 1. The finger 6 carries the pin 6a on its uppermost edge, as seen in the drawings, near the end of said finger 6 closer to the spool holder portion 1a. The other end of the finger 6 extends beyond the confines of the side plates 1, but not so far as the arm 2, and said other end has an upwardly directed projection 61), which in this embodiment is substantially hemispherical. The projection 6b constitutes a tape displacing member and can be urged towards the Web 2b. In the rest position of the devices, shown in FIGURE 1, the projection 6b is displaced from the web 2b. The finger 6 has a substantially semi-circular projection he from its lower edge arranged oppositely to the pin 6a and said finger 6 is apertured concentrically with said semi-circular projection 60, the aperture accommodating a pivot pin 7.

A manually operable lever forming actuating means for the device, is mounted between the plates 1 and comprises an outer sleeve 3 and an inner sleeve 4. The outer sleeve 3 projects from the plates 1 near the hand grip portion 10 so that said lever can be actuated in the manner of a trigger in a one-handed operation whilst gripping the portion 10.

The other sleeve 3 is mounted on a fulcrum 3b secured to the body portions 1b of the plates 1, and the inner sleeve 4 is slidably mounted with respect to the outer sleeve 3 and projects from the upper end of said sleeve 3 as seen in FIGURES 1 and 2. The inner sleeve 4 has a bifurcated upper end 4a, as can be seen in FIGURE 3, which embraces the semi-circular projection 6c and carries the aforesaid pivot pin 7. The sleeve 4 is thus coupled to the finger 6 via said pivot pin 7. The finger 6 is urged by a compression spring 5 against the shoe 13, the spring 5 being retained between a closed end 3a of the sleeve 3 and the periphery of said projection 60 of finger 6 as can be seen in FIGURE 1.

A return spring 9 is provided for the

lever comprising sleeves

3 and 4, the spring 9 being coupled at one end to a slidable saddle 8 on the part of the sleeve 4 which projects from the sleeve 3, and the other end of said spring 9 is fixed in position by being coupled to a rod 12, secured between the plates 1 and visible in FIGURE 1. The spring 9 is also passed over a guide roller 16 mounted on a fulcrum 11 secured to the plates 1. If desired, more than one, for example two, return springs may be provided, both coupled to the saddle 8, passing over the 4 same or separate guide rollers, and being fixed at their other ends.

Also mounted between the body portions 1b of the plates 1 is a pawl 15, forming restraining means for the tape being dispensed, and which in the present embodiment is in the form of a strip of material having one end 15a pivoted on pivot pin 15c and having its other end 15b bifurcated as can be seen in FIGURE 1. The extremities of the bifurcated end 15b are urged towards the web 2b by means of a spring 15a, and the finger 6 extends between the forks of said bifurcated end 15b. The arch formed by the forks of said bifurcated end 1512 conveniently acts as a stop for finger 6 as will become apparent hereinafter.

A spindle 1a is mounted between the spool holder portions 1a and is detachable from said portions 1a so as to be suitable for carrying a spool of adhesive tape to be dispensed. Moreover, as can be seen in FIGURES 1 and 2 a closure member 14 may be provided where indicated substantially to enclose the space between the plates 1.

In order to use the device described above a length of adhesive tape, indicated by reference 16, is unwound from a spool of tape and is applied between the pin 6a and the base 13b of the shoe 13 and then directed along the web 2b between said web 2b and the pawl 15, the adhesive side of the tape facing downwardly as viewed in the drawings. To facilitate the threading of the tape into the device the end 16b of the tape may be adhesively connected to a thin strip of rigid material (not shown) which is threaded through the path required for the tape until the end 1611 extends beyond the cutting edge 2d. The tape is then severed on said edge 22! to detach it from the aforesaid strip. The roll carrying the adhesive tape is then aligned with the spool carrying portions 1a of the plates 1 so that the spindle hi can be inserted in apertures in said spool carrying portions 1a and through the roll. Alternatively the spindle 1d may be inserted through the roll and then applied to the spool carrying portions in by the provision of suitable radial slots (not shown) in said portions 1a. Once threaded as described above the adhesive tape is held in position on the web 2b by the pawl 15, but if desired guide members may be provided for the tape beyond said pawl 1'5. The adhesive tape is is then ready to be dispensed. The end 1615 of the tape is applied with its adhesive side in contact with an article and the hand grip portion 10 is held in one hand. One or more fingers of this hand are applied to the

lever comprising sleeves

3 and 4, for example the forefinger may be used for this purpose. The lever is actuated in the direction of the arrow in FIGURE 2 to dispense a length of tape. This actuation of the lever causes a toggle action of the finger 6 by virtue of the pin and inclined slot connection 6a, and the compressive coupling between finger 6 and shoe 13, and also displaces said shoe 13 and finger 6 in the direction indicated by the arrow in FIGURE 2, i.e. from right to left in the drawing. Initially the shoe I3 is at the extreme right hand end of the slot formed between

lines

22, 2e, and the pin 6a is at the right hand end of the slot 130. This initial position is shown in FIGURE 1. Displacement of the lever applies a force to the finger 6, which causes said finger 6 to pivot in the clockwise direction until the projection 6b comes into pressing contact with the adhesive side of the tape. This occurs in the first part of said displacement and said displacement also initially causes the pin 6a to traverse the slot 130 to the other end thereof whereupon said pin 6a comes into engagement with the adhesive side of the tape 16. Continued displacement of the lever then displaces the finger 6 and with it the shoe 13 in the direction of the arrow in FIGURE 2, this displacement being limited by the shoe 13 hearing against the end of the slot formed between

lines

26, 2e. During this displacement the projection 61; and the pin 60 being in contact with the adhesive side of the tape 16 displace said tape by a corresponding amount, causing a length of tape to be drawn past the pawl and withdrawn from the spool. In FIGURE 2 the lever, finger 6 and shoe 13 are shown at an intermediate position during displacement thereof.

The lever is subsequently released whereupon it returns to its initial position by means of the return spring 9. Initially release of manual pressure on the lever removes the pressure on finger 6 causing said finger 6 to pivot in the anti'clockwise direction whereby the projection 6b moves away from the web 2b and so no longer applies a pressure on the tape 16. This anticlockwise pivotal movement of the finger 6 is limited by engagement of said finger 16 on the arch between the forks of the bifurcated end 15b of the pawl 15. The action of the return spring 9 causes the pin 6a to move from left to right in the slot 130, thereby releasing the pin 6a from its pressing contact with the tape, and cause the shoe 13 and finger 6 to be returned to their initial positions. During the return of shoe 13 and finger 6 to the initial position, the pin (in and projection 6b, being released from their pressing contact with the tape 16, do not displace said tape 16 in the reverse direction, said tape being held in its withdrawn position by the pawl 15. The

lever comprising sleeves

3 and 4 can be actuated subsequently to withdraw further lengths of tape 16 until the required length is obtained. The tape 16 may then be severed by orientating the device so that the cutting edge 2a' is applied to the tape 16 to sever it.

If the

lever comprising sleeves

3 and 4 is actuated through an angle smaller than its largest permitted angle the shoe 13 is displaced by a distance less than that permitted by the slot defined by

lines

2e, 22. Thus a shorter length of tape is withdrawn from the spool. In this Way, by controlling the angle through which the lever is actuated the length of tape dispensed may be regulated up to a maximum length corresponding to the maximum possible displacement of said lever.

In order to facilitate the threading of adhesive tape 16 through the path required for said tape in order that the device described above may be used to dispense said tape, the device may be modified by providing a hinged panel in one of the side plates 1 which can be displaced to provide access to the shoe 13. By way of example said shoe 13 may be provided with a further slot communicating with the slot 130 and leading to the lowermost extremity of each side arm 13a so that the pin 6a may be removed from the slot 136 whilst the tape 16 is being applied to the device, by depressing the sleeve 4, and then introducing into said slot 13c over the tape 16.

In a modified embodiment of the invention the cutting edge 20. is replaced by a cutting mechanism comprising means for piercing the tape at an intermediate position of its width with a pair of piercing and cutting members and for displacing said members away from each other to sever the tape across its Width. A tape dispensing device having one such cutting mechanism is illustrated in FIGURES 4 and 5 in which parts of the device which correspond to parts of the device of FIG- URES 1 to 3 are given the same reference numerals. The device is similar to that of FIGURES l to 3 except that the end of the web 2b of arm 2 is not turned upwardly and tapered to form a cutting edge. Instead the side members 2a are provided on their exterior surfaces with extension plates 20 which extend beyond the end of the web 21; and may be tapered as indicated in FIG- URE 5. The extension plates 20 carry at their free ends between them a pin 21 on which is mounted a roller 22, the roller 22 being spaced from the end of the web 2b as shown.

A pair of levers 23 one on each side of the plates 1 as shown are mounted on a common fulcrum 24 which passes through the plates 1 and are each provided with a handle 25. The levers 23 are integral at their upper ends as viewed in FIGURE 5 forming a cross member 23a which is most clearly seen in FIGURE 4 and which can bear against the spool carrying portion 1a of the plates 1 as shown, which portion forms a stop for the levers 23 as will become apparent hereinafter. The cross member 23a has coupled to it one end of a bar 26 which extends lengthwise above the arm 2 as viewed in FIG- URE 5 and is coupled at its other end to a slide 27. The slide 27 is urged towards the right hand end of the arm 2 by means of a tension spring 28 coupled at one end to said slide 27 and at the other, for convenience, to the fulcrum 24 as can be seen in FIGURE 4. A bar 29 mounted between the plates 1 above the web 212 as viewed in FIGURE 5 serves as a stop for movement of the slide 27 from left to right. The bar 29 also pivotally supports one end of a pair of piercing and cutting members 39 each of which is in the form of a rod having a downwardly turned free end 30a which is tapered to a point and arranged to lie substantially over the space between the end of the web 2b and the roller 22. The rods 30 are tensioned, for example by spring means not shown, so that the ends 39a are urged together. The slide 27 contains a pair of grooves one on each side thereof which are arranged to accommodate the rods 30, said slide 27 having a central portion 27a which resides between the rods 36. This can be seen most clearly in FIGURE 4. The rods 36 have oppositely disposed inwardly directed projections 39b which in the initial position of the cutting mechanism, shown in the drawings, lie just to the left of the central portion 27a of slide 27.

In order to use the cutting device, when the required length of tape has been dispensed in the manner hereinbefore described with reference to FIGURES 1 to '3, the device is held with the non-adhesive side of the tape passing over the roller 22 and in engagement with the web 2!) and so that the tape is under tension. The levers 23 are then actuated employing one of the handles 25 to pivot said levers anti-clockwise about the fulcrum 24. This may be effected by a finger or fingers of the hand holding the hand grip portion 10. Initially, due to the effect of the tension spring 28, the slide 27, and with it the rods 30, is held inclined upwardly from the arm 2 as can be seen in FIGURE 5 so that the cutting ends 30a of said rods 30 are spaced from the tape 16 and are close together. The first part of the pivotal movement of the levers 23 causes the bar 26 to pivot the slide 27 about the bar 29 thus moving the ends 30a of rods 30 into engagement with the tensioned tape 16 and causing said ends to pierce said tape intermediate its width. Pivotal movement of the slide 27 is stopped when said slide and the rods 39 bear against the top surface of the web 2b, or other stop means provided on said surface. Thereafter further actuation of the levers 23 in the same direction moves the slide 27 against the action of the spring 28 from right to left along the arm 2. This causes the central portion 27a of the slide 27 to come between the projection 30b on the rods 30 thereby urging said rods 30 apart so that the cutting ends 30a are also moved apart and sever the tape 16 across its width. When the levers 23 are released the spring 28 returns the slide 27 to its initial position. At first the slide 27 moves from left to right along the web 21; thereby allowing the cut ting ends 30:: of the rods 3% to come together again, this movement of the slide 27 being terminated when said slide 27 reaches the bar 29. Thereafter continued action of the spring 28 causes the slide 27, and with it the rods 30, to pivot about the bar 29 in the clockwise direction until the cross-member 23a of the levers 23 bears against the spool carrying portion 1a of the plates 1. This is the initial position of the cutting mechanism as shown in the drawings.

In a further modified embodiment of the invention, the form of pin 6a and its attachment to finger 6 may be advantageously modified from that described above with reference to FIGURES 1 to 3. Such an embodiment is illustrated in FIGURE 6 which shows pin (in rotatably coupled, rather than fixably secured, to the finger 6 by passing through a hole made in an upward projection 6d from the rear end of finger 6. In addition, the pin 6a is provided with roller means 6e on each side of projection 6d, the rollers in question preferably being of coil spring or like form, as shown in FIGURE 6. The radial extent of the roller means 6e exceeds that of the projection 6d so that the latter does not contact the tape during a tape feeding operation.

Regarding the advantage of this further embodiment: the roller means provide a smoother and facilitated release action from the tape when spring 9 is operating by virtue of rolling action, and this is enhanced with use of coil form compared to sleeve form roller means. Naturally, it is not essential for this action that both the pin 6a be rotatable in finger 6 and the roller means 62 on the pin 6a, but the latter facilitates assembly and the former is useful for other purposes.

Concerning this last point of pin (in being journalled, or rather removably located in finger 6, this is useful in connection with yet further arrangements in accordance with the present invention whereby the lower or actuating part of the device can be connected with upper or slide parts of different width for use with tapes of respectively different widths. Thus a common trigger part can be re movably connected with any of a set of slide parts and separation of the parts involves removal of pin 6a.

Although the invention has been particularly described with reference to the specific embodiments thereof shown in the accompanying drawings various modifications may be made to said embodiments without departing from the scope of the invention as set out in the appended claims. For example, in one alternative construction, the elfectively reciprocatory tape feed driving movement of pin 6a may be replaced by a pawl or stepping operation by use of a different element pivoting in holes in place of slots 130.
