2 Claims. (01. 21650) This invention relates to devices for dispensing and applying labels and tapes having a pres sure-sensitive adhesive coating.

Labels of the character referred to have heretofore been produced and mounted in single file on a tape-like backing strip. To remove the labels from the backing strip and to dispense the same, they are merely successively peeled from the strip. Likewise, tape having one surface coated with a pressure-sensitive adhesive has been heretofore produced with a similar and registering backing strip overlying the adhesive surface of the tape. To use the tape, it and its backing strip are peeled apart.

It is the principal object of my present invention to provide an improved, simple and inexpensive device for dispensing and applying labels and tape of the character referred to in which the labels or tape are peeled from the backing strip as they are dispensed and applied.

It is a further object of my invention to provide a device of the character referred to which peels the label or tape material, strips the labels or tape from the backing sheet and properly applies the label or tape to the desired surface with a single manipulation of the device.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. l is a view in side elevation of a label and tape dispenser and applicator, showing one side wall removed to more clearly show the construction and. operation of the device. 7

Fig. 2 is a view in vertical section through the same taken on line 2-2 of Fig. 1-.

Fig. 3 is a fragmentary view illustrating one type of material which may be dispensed and applied by my improved device.

Referring more particularly to the accompanying drawings, in Fig. 3 I have illustrated, by way of example, one type of material which may be dispensed and applied by my improved desired, in that my device is operative to dispense and apply longitudinally spaced labels mounted on a strip of backing sheet or a continuous tape mounted on the backing sheet.

The dispenser or applicator embodying my invention is generally indicated at l2 and is relatively light and small so that it may be grasped in the hand of the user and manipulated. The device comprises a casing [4 here shown as formed of a marginal wall l5 and two side walls [6 and lfia. These latter walls are in parallelism, of course, and are spaced apart by the annular wall I5.

The side wall [6a is detachably associated with the marginal wall l5 and the other side wall [6 in order that it may be removed. to expose a cylindrical chamber H in the casing. This chamber I! is cylindrical and is adapted to receive a supply roll I8 of the material to be dispensed.

' In the chamber I! the wall I6 is formed with a concentrically locatedtrunnion 19 which projects axially therefrom' toward the wall l6a. This trunnion is provided to rotatably receive thecore 20 of the roll of tape-like material 18 to be dispensed.

The side wall I611 is formed with a concentrically located axially projecting pintle 2| adapted to engage anaxial bore 22 in the trunnion I9 to aid in aligning the side walls l6 and [6a relative to each other and to maintain the same in rigid relationship. If desired, the fit between the pintle 2i and thebore 22 may be such that there will be sufiicient friction between the two to maintain theside walllfia. properly positioned relative to the side wall [6, but enabling the same to be detached therefrom.

One side of the casing is formed with anoutwardly projectingframe 9, as shown, to act as a mounting for an applicator roller 23 and'a pair of feed rollers 2 1. -The outer-face of theframe 9 of the casing is fiat and is disposed on a plane parallel to-the-axis of the chamber l1; Theframe 9 extends forwardly and rearwardly of the vertical center line of the'chamber approximately equal amounts, and its lateral di,-

mension is, of course, the same as that of the casing.

At the forward end of this frame 9 I rotatably mount the applicator roller 23, which is rotatable about an axis which is parallel to the axis of the chamber. The applicator roller 23 is, of course, parallel to the axis of the chamber.

At the 'rearmost end of theframe portion 9 of the casing are the twofeed rollers 24 which are likewise rotatable about axes which are parallel to the axis of the chamber IT. Therollers 24 are of equal diameters and they are so mounted in theframe 9 and relative to each other that they will frictionally engag a backing strip led therebetween.

It will be noticed that the periphery of the lowermost roller projects beyond the outer flat surface of the frame portion of the casing, while the periphery of the applicator roller 23 is in approximately the same plane as that surface.

. Therollers 23 and 24, of course, are rotatable about axes parallel to the axis of the chamber IT, as illustrated in Fig. 2.

I form adischarge slot 25 from the chamber ll through theframe portion 9 of the casing. Thisdischarge slot 25 commences approximately at the vertical center of the chamber and extends tangentially forwardly at an acute angle to the outer flat surface of the frame portion of the casing and extends through such surface at a point 'just short of the. applicator roller 23.

' I form asecond slot 26, which I prefer to term a feed slot, which extends through the outer fiat surface of theframe 9 at a point spaced a very short distance rearwardly of-the mouth of thedischarge slot 25, and which extends substantially parallel to thedischarge slot 25 for the length of the latter, and thence rearwardly through the rearmost end of the frame. Thefeed slot 26 is so located thata tape led therethrough will pass centrally between thefeed rollers 24 and be engaged thereby.

The spacing between the slots forms a relativelythin peeling tongue 21 which extends substantially tangentially of the chamber [1. The outer terminal of this tongue is located at a point substantially in the same plane as the outer flat surface of the frame.portion 9 of the casing.

While I refer to theslot 25 and the inner surface of thetongue 21 as being substantially tangential to the chamber H, I wish it understood that I may, as illustrated, slightly how the tongue for ease in passing a tape thereover.

Thetongue 21, of course, is positioned in radial alignment with the chamber [1; and. extends laterally between the side walls It and Ilia so as to be of the same width as the chamber. The outer terminal of thetongue 21 is relatively thin and forms a peeling edge, as will be described, to peel the backing sheet from the labels or tape.

' In use of the device, a supply roll of the tape or label material is rotatably fitted on the trunnion l9 and thus will be substantially concentrically mounted in the chamber ll of the casing. The end thereof is then threaded forwardly. through thedischarge slot 25 and the backing sheet is partially stripped from the labels and reversely'turned upon itself under thetongue 27 and, thence rearwardly. through thedischarge slot 26 between therollers 24 and thence outwardly through the rearmost end of the casing. The conditions just described will be substantially those shown in Fig. 1.

Assuming that the casing is grasped in the hands of the user and moved rearwardly (to the right with reference to Fi 1) along the surface 4 vice along the surface A. Due to the folding of the backing strip around the peeling edge of thetongue 21, the labels will be stripped or peeled from the backing strip at that point and will be deposited so that their upper surafces will be engaged by the applicator roll 23, which will apply sufficient pressure thereto, to cause the labels to adhere to the surface A.

Thus, it is seen that in the case of labels mounted in longitudinally spaced relation on a tape, these labels can be rapidly applied in the same relative positions to a surface over which the device is traversed as they assumed on the tape, and can be arranged in patterns by proper manipulation of the device, if so desired.

It should also, be apparent that if a tape is substituted for the labels II, that it can be applied over a surface in the same fashion because the tape earing the adhesive surface will feed forwardly under the applicator roller, while the waste backing strip will discharge rearwardly from the device between thefeed rollers 24.

Also, it is seen that labels on a continuous strip can be applied singly, if so desired.

From the foregoing it is obvious that I have provided a very simple and efficient label and tape dispenser and applicator which has a wide variety of uses, and which may be efiiciently used to expeditiously successively apply separate labels or continuous tape to desired surfaces.

While I have shown the preferred form of my invention, it is to. be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described. my invention, What, I claim and desire to secure by Letters Patent is:

l. A device of the character described comprising a casing for rotatably supporting a roll of label material composed of an adhesively coated layer and a continuous backing strip separably adhered together, a peeling edge relatively fixed t0 the casing and disposed at a point to receive the end of the material led substantially tangentially from the roll, said peeling edge being so formed that when the backing strip is folded thereover it will be running in a direction substantially. opposite the direction in which the material is led from the rolL to the peeling edge whereby to effectively separate the adhesively coated. layer from the backing strip at thepeeling edge, feeding meansto engage the backing strip as it is led from the peeling edge, means mount-1 ing said feeding means for engagement with a surface and movement With the casing over said surface in a direction substantially opposite to that in which the material is led from the roll to the peeling edge, and applying; means arranged adjacent thepeeling means to engage the layer peeledfrom the backing strip and apply the same to. a surface.

2. A device of, the character described comprising a casing for rotatably supporting a roll of label material composed ofan adhesively coated layer and a continous backing strip separably adhering together, a peeling tongue carried by the casing and extending substantiallytangentiallywith respect to a roll; mounted on the casing whereby the material of the roll may be led substantially tangentially from the roll. over the tongue, the. outer terminal of said tongue constituting a peelingv edge over which the backingstripmay be acutely folded whereby to effect separation of the adhesively coated layer and they backing strip, a pair of feed rollers carried by the casing on axes parallel to the axis of revolution of the roll and between which the backing strip may be led after being folded over the peeling edge of the tongue, said rollers being operable by engagement with a surface and movement of the casing over said surface to unwind the material from the roll and cause separation thereof at the peeling edge, a rotatable applying roll carried by the casing closely adjacent to the peeling edge of said tongue but on the side thereof opposite the feed rolls and capable of engaging the adhesively coated layer as it is peeled from the backing strip to apply the same to the surface over which the device is moved.
