((1242-5515) This inventionrelatesto adhesive tape dispensing devicesand has particular reference to 'devices for holding a portion of the tapeadjacent its'free end, in easy grasping position whereit is available fir withdrawing desired lengths of the tape from-the spook; v I

Numerous types of containers nd devices have been placed 'onlthe market for holding and dispensing tacky, adhesive coated-tape or-strip materialfrom a roll carried or enclosed in a housing or-. container for. withdrawing arid-severing desiredlengths of the tape therefrom. In many instances these deyices are unsatisfactory because the knives or cutting edges provided for severing the tape become gummedup with adhesiye and-frequently the adhesive co'ated side 'stic ks to the wallsrof the housing or onto the roll proper making it -,difficult-to locate the free end of the tape for continued feeding of the tape to the cuttingknifer V .Thepre'sent invention contemplates, overcoming these difliculties by providing ,a dispensing device in which the adhesive coated surface of the tape will be kept out of contact with the cutting edge of the knife and alsb in which the leading or free end of thetape, following a sevring operation', willbe shifted away frornthe knife andheld-ineasy grasping p'ositionfor a subsequent tape dispensing operation.

An objectof the invention is the provision of. a dispensing deyice for a roll of tapeor strip inaterial having one of its surfaces coated with a tackyfor pressure sensitivewadhesiv wherein the roll is rotatably carried in an efli'cientmanner with the free end 'of the tape extended in a position for easy grasping to enable desjredlengths of the tape to be withdrawn andsevered from the roll asmay be; required. i

Another object-is the provision of a dispensing device of :the character described wherein a free or cut end of an unwound portion .of a roll'oftacky tape following F a tape severing operation shifted away from the cutting blade or knife and disposed outwardly in an open space where it-rnay be easily grasped preparatory to the next tape withdrawing and severing operation.

Another. object is the provision in such a dispensing device of a movable or yieldable pressnreexerting element located in thfepa'th' of theunwound tape and en: gageable with the uncoated surface thereof during a tape dispensing operation without marr ing the tape and also engageable with the uncoated tape surface following every tape severiiig operation forurging an unwound portion of the tape against a stationary support element to hold the tape and simultaneously shift the free severed end =of the tape away-frond the cutting knife and into an extended position where it is'easily grasped for a subsequent tapeldispensing operation.

Numerous otherobjects and advantages of the inverition'willgbe apparent as itis better understood from the following description; .Which taken in c'onnection'with the accompanying drawings, disclosesia preferred embodiment thereof.

As a preferred orleiremplary embodiment of the invention Figs. 1 to 4 of the drawings illustrate a substantially rectangular shaped tape dispensingdevice including a receptacle, container or housing 15 to ,accorlrimodateadg hesive or other tacky tape in roll form and to permit it to be dispensed by unwinding and severing stripsiof desired length therefrom. If desired the receptacle, con-..

tainer or housing 15 may be made. oblo'n'g with rounded ends.

The container or housing licoinprises apair of spaced,

side members or plates 16-, 17 formed of sheeftrnetal and a tubular-form body 18 disposedbetween the plates and defining top and bottom walls 21.22am front and rear end walls 23, 24 (Figs. 1 and 3). I i

The

side plates

A Po ti nv 33 The side plate or cover 17 thus hingedly connected to the side of the container 15 permits easy access to the interior of the container through a filling opening for loading a roll of tape into the dispensing device. With the container temporarily in an open. position as best illustrated in Fig. 3, a roll of tape 26 may be readily inserted in place on the flange or spindle 26 of the side plate 16. An end portion 48 of the tape preferably is unwound from the roll just before positioning it in the dispenser and this unwound end is extended outwardly through the opening 32 provided for this purpose.

The tape on the roll 27 is of the type which has only one of its surfaces or faces coated with a tacky pressure sensitive adhesive. This coated surface usually is toward the roll. Thus as the unwound portion is fed through the opening 32 the upper or coated surface of the tape (as viewed in Fig. 3) engages against the stationary support curl 34. The tape temporarily is held in this position by a movable or yieldable pressure exerting element 51 so that the outermost free end of the tape is disposed outwardly in space where it is easily grasped for withdrawing strips or portions of the tape from the roll.

The pressure exerting element 51 in the present embodiment comprises a spring formed preferably from spring wire bent to provide a curl 52 intermediate its length and having one end of the wire bent into a substantially U-shaped section or pressure arm 53 (Figs. 1 and 3). As shown, this arm extends from its center of oscillation adjacent the edge 36 inwardly toward the roll 27 a distance slightly greater than the distance between the oscillation center and the tape support 34. The arfn is also biased toward the support 34. The opposite end 54 of the wire 51 is bent to extend down along the front end and along the bottom adjacent one side of the container where it is secured by solder or in any other suitable manner.

During a withdrawing operation the free extended end of the unwound portion 48 of the tape is grasped and drawn away from the curled edge 34 and outwardly of the dispensing device (Figs. 1 and 3). The uncoated surface of the tape bears against and slides over a transverse leg 55 of the U-shaped section 53 of the spring 51 depressing it into the position as indicated by the dot and dash lines in Fig. 3, and the tape is withdrawn along a tape dispensing path also shown in Fig. 3 as a dot and dash line extending from the roll outwardly and over the cutter 36. When a desired length of tape is withdrawn, the uncoated surface of the inner end of the strip is brought down against the serrated cutting edge 36 and severed from the roll.

Immediately following such a withdrawing and severlng operation the leg 55 of the spring 51, hearing against the uncoated surface of the unwound portion 48 of the tape, urges it back toward the stationary support or curled edge 34 and grips the tape with a slight pressure. The tacky coated surface of the tape engages and adheres to the curled support edge 34 substantially along a line contact without marring the tape.

This action of the st ring 51 on the severed or outer free end of the unwound portion of the tape pulls it away from the cutting knife 36 into a free extended position as best illustrated in Fig. l where it is gripped between the spring and the support 34 and is readily accessible for a subsequent tape dispensing operation.

As another form of the invention Figs. to 8 of the drawings illustrate a circular or drum shaped body, receptacle or container for housing a roll of tape and havmg a partially opened elongated extension formed at one side for housing the tape cutting and tape gripping instrumentalities wherein the unwound end of the tape may be held in readiness for dispensing purposes.

The drum shaped container comprises a pair of spaced side members or

plates

61, 62 formed of sheet metal, a body 63 of metal disposed between and joined to the plates and a metal hinged wall or cover 64 (Figs. 5 and 7).

The marginal edges of the

side plates

61, 62 preferably are formed with laterally extended

flanges

65, 66 along substantially half their periphery and with beaded and hemmed edges 67 along the remainder. The

flanges

65, 66 extend along the bottom half including the circular portions of the side members and continue into the elongated extension for uniting the body 63 therewith. The headed and hemmed edges 67 extend along the upper circular half and the adjoining elongated extension (Fig.

5) for providing smooth and reinforced edges along the top of the container.

The body 63 is formed with a semicircular portion 68 which provides the bottom for the drum shaped body (Figs. 6 and 8). At an intermediate part of this body 63, the circular portion terminates in a bridge or barrier 71 which is bent and extended into a straight bottom portion 72 for the elongated extension. At its forward end the bottom portion 72 is curved upwardly and terminates in a serrated cutting edge or knife 73. A hinge lug 74 is formed on the end of the body 63 opposite the cutting knife 73 (Figs. 6, 7 and 8).

The cover 64 is semicircular in outline (Figs. 5, 7 and 8) and along its longitudinal edges is beaded outwardly to provide channels 75 on the inner face which channels are adapted to surround the beaded and hemmed circu lar edges 67 of the container body. At one end the cover is provided with spaced hin e lugs 76 which co-operate with the hinge lug 74 of the body 63 for connecting the cover to the container. At its opposite end the cover is bent into a curved section 77 which terminates in an outwardly curled edge 78 which provides a stationary support for the tape being dispensed when the cover 64 is in closed position (Fig. 6). The beaded edges of the cover defining the channels 75 are cut away at this latter or inner end so that the bent section 77 and the curled edge 78 may enter between the

side plates

61, 62.

The cover 64 is retained in its normal or closed position by a protuberance 81 which is pressed inwardly in each of the side plates 61, 62 (Figs. 6 and 8) and these protuberances register with the inner circular wall of the curl 78 when in the position illustrated in the latter figures and provide snap buttons for holding the cover closed.

During the assembly of the container parts, the

flanges

65, 66 of the

side plates

61, 62 are secured by soldering to marginal overlapped edges of the

portions

68, 72 of the body 63. The hinge lugs 74, 76 are also united by a pintle 82 for hingedly connecting the cover to the container.

In order to keep the free unwound end of the tape in easy grasping position a yieldable pressure exerting element 83, similar to the ressure exerting spring 51 hereinbefore described, is provided and secured in position within the elongated extension. For this purpose the spring element 83 has one end 84 extended along the bottom adjacent one side of the extension where it is secured by solder or by any other suitable means. The opposite end of the spring element 83 is provided with a transverse leg 85 which is similar to the leg 55 of the spring hereinbefore mentioned.

A roll of tape 27 is loaded into the instant dispenser by swinging the hinged cover 64 to an open position. An unwound portion of the tape extending from the roll and having its tacky coated surface on top as viewed in Fig. 6 is extended outwardly over the barrier 71 and the transverse leg 85 of the pressure exerting element.

When the cover is swung inwardly into its normal or closed position the tacky coated surface of the unwound portion of the tape engages against the stationary support 78 where it is held by the yieldable spring element 83 with the outer free end of the tape extended into easy grasping position as best illustrated in Figs. 5 and 6.

During a tape withdrawing operation the roll of tape is freely rotated in the circular or drum shaped end of the container and is engageable against the barrier 71 and the inner end of the circular wall of the cover 64 (Fig. 8). As the tape is dispensed the uncoated surface thereof slides over the transverse leg 85 of the pressure exerting element 83 depressing the element to the position shown in the latter figure and is withdrawn along a tape dispensing path extending outwardly over the cutter 73. When a desired length of the tape is thus withdrawn, the uncoated surface of the tape is brought down against the cutting knife 73 and the tape severed from the roll.

Following a dispensing operation, the leg 85 of the pressure element 83 like the leg 55 of the element 51 previously described, bearing against the uncoated surface of the unwound portion of the tape, urges the tape back toward the stationary support curl 78 of the cover 64 where the tacky coated surface of the tape engages and is held for a subsequent dispensing operation with the outer free end of the tape disposed in easy grasping posi tion as illustrated in Figs. 5 and 6.

As a still further form of the invention, Figs. 9 and 10 of the drawings illustrate a cast block housing 91 having spaced side walls 92 and spaced front and rear walls 93, The housing 91 preferably is supported on rubber or cushioned legs or plugs 95.

A roll of tape 27 is rotatably mounted in the space between the walls and for this purpose the fibre core 28 is slipped onto a central hub 96 having trunnions 97 which extend outwardly on opposite sides thereof. The ends of the trunnions 97 enter into open ended grooves 98 formed in the inner faces of the side walls 92.

Provision is made in the instant embodiment for holding an unwound portion of the tape in place so that the free outer end of the tape is disposed outwardly at the front end of the dispenser where it is always available for withdrawing purposes. For this purpose a stationary support 101 is provided against which the tacky coated surface of an unwound portion of the tape engages. The roll of tape with its unwound portion preferably is positioned in the dispenser in such a manner that the tacky iz oatedosurface of the tape is face down as illustrated in The stationary support 101 is formed as an outwardly curled edge at the upper end of a sheet metal bracket 102 which is secured to the top sloping face of the front wall 93 of the dispenser. The tacky coated surface of the tape normally is held against the support 101 by a pivotally carried gravity pressure exerting element or swinging weight 103 which is pivoted on a pin 104 carried in a substantially U-shaped bracket 105. This bracket 105 like the bracket 102 also is secured to the top of the front wall 93 preferably adjacent or together with the same (Fig.

The lower end of the weight 103 is rounded so that the uncoated surface of the tape will pass readily beneath it during a dispensing operation and also that only a narrow transverse section of the tape is in slight pressing engagement with it when an unwound portion is held against the stationary support 101.

During a tape dispensing operation the roll of tape is freely rotated on its pivotal mounting in the housing 91. As the tape is dispensed the uncoated surface thereof slides beneath the rounded edge of the pivoted weight 103 and swings it inwardly and upwardly to a position substantially that shown in dot and dash lines illustrated in Fig. 10, and the tape is withdrawn along a tape dispensing path also shown in Fig. 10 as a dot and dash line extending from the roll outwardly and over the cutter 106. When a desired length of the tape is withdrawn from the roll it is drawn taut against a serrated edge or cutting knife 106 formed on the outer edge of a transverse section 107 of the U-shaped bracket 105 for severing the tape from the roll.

Following a dispensing operation the swinging weight 103 bearing against the uncoated surface of the unwound portion of the tape deflects the tape down toward the stationary support 101 where the tacky coated surface of the tape engages and is held for a subsequent dispensing operation with the outer free end of the tape disposed in easy grasping position as illustrated in Figs. 9 and 10.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
