' 25 Claims.

This invention relates to an improved apparatus for serving measured lengths of strips or tape which are covered or impregnated On. one side thereof with a pressure sensitive adhesive usually tacky or non-drying either permanently or during the period of use. The invention has particular utility in the various fields of use to which pressure sensitive adhesive tape is applied and I I especially is useful where the tape is required in short lengths such as fractional parts of a foot. It eliminates the tedious nuisance and waste involved in cutting inaccurate lengths with ordinary scissors and provides a simple and easy operating mechanism for speedily stripping from the roll, measuring, cutting anddelivering at a point ready for use, the desired length of tape.

The improved apparatus contemplates mechanical means for stripping the material or tape from the roll in predetermined lengths and comprises generally a compact serving apparatus particularly designed to be carried in the pocket of the user and when in use, to be held in one to be moved about its pivot in a direction away from the roll to draw tape from the roll for a predetermined distance whereby a predetermined length of tape is drawn from the roll. Means are provided for releasing the pivoted element at the end of its arc of movement and for retuming it to its original position as well as means for severing the tape which means may be associated with the element. Also are provided means for varying the arc of movement of the element about its pivot so that the lengh of tape delivered may be varied.

It is an object of the invention to provide a pocket size delivery apparatus for tacky tape par ticularly adapted for speedy and convenient serving of small strips of relatively narrow tacky material although it will be of course understood that while the size of the construction is a feature, the invention is not to be limited to this feature and the dispenser or the principles of the invention involved therein may suitably be applied to the delivery of larger strips of wider web material.

It is a further object of the invention to pro vide a pull-out dispenser for tacky tape having a support for theleading or free end of the tape against which rests the non-tacky side of the tape and which is of such a nature as to permit the finger of the operator to be app to the tacky side of the leading end of the tape in an endwise direction so that the tap is drawn out in line with the axis of the finger. Thus the cut of! piece of tape adheres to the finger in endwise alignment with the finger so as to be readily applicable to the surface to which the tape is to be applied. The edge of the tape supporting member may provide a tear-oil! edge for tearing off the free end of the tape while adhered to the finger. Also mounted adjacent to the support for the leading end of the tape an adhesion member is provided to which the tacky side of the tape adheres and is thereby held in position adjacent to the tape end support.

Further objects and advantages will appear from the following description and the drawing in which:

Figure 1 is a side elevation of the device with one side wall removed showing the tape delivery apparatus, the device being shown held in the hand of the user with the other hand of the user in the act of withdrawing a strip of tape;

Figure 2 is a view similar to Figure 1 showing a further step in the removal-of a strip of tape, 0 and Figure 3 is a vertical longitudinal section taken on the line 3-3 of Figure 2.

Referring now to the drawing, the device includes an outside casing II) which may be of metal, plastic or any other convenient relatively durable material, such a material as Bakelite having been found particularly advantageous. The case III is preferably formed of two interlocked frame members I! and I, each of which has the end toward the tape delivering portion of the machine open. Interlocking of the side flanges of the frame members at the rear of the device is preferably accomplished by the flange l6 which keys with the edg of the portion II. The two case members are held together at the front portion of the machine by the lock post It. Obviously any other convenient means desired may be employed as a covering for the apparatus, it only being necessary that suflicient rigidity for mounting of the various parts be provided.

The portion I4 is provided with the inwardly extending boss 20 and the portion I2 is similarly provided with a complementary boss 22 which have mounted between them the shaft 24 upon which the roll 26 of. strip material 28 may conveniently be mounted. The interior of the casing is also provided forwardly of the mounting of the roll 28 with complementary bosses 28 and 88 which mount between them the tape guide roller 82. Similarly interiorly mounted bosses 84 and 88 carry pivot 88 upon which is pivotally mounted tape delivery element or yoke 48 which is normally spring pressed by spring 42 into the rearward position shown in Figure 2. As illustrated in Figure 3, the yoke 48 includes side members descending downwardly from the pivot 88 and a base member 42 which joins the side members, and constitutes a support for the leading end of the tape. The base 42 is preferably apertured as at 44 and also extends forwardly of the side members of the yoketerminating in =a cutting edge 46 which may be serrated to facilitate cutting if desired.

The forward movement of the yoke 48 about the pivot 88 is limited by a pin 48. Each of the walls I2 and I4 are provided as shown in Figures 2 and 3 with toothed apertures 58 which may be cut through the walls as shown. The pin 48 may fit into the recesses between the teeth in the aperture 58 and will be held in position in whatever recess it is placed by the spring 52. It can be seen therefore that the pin 48 may be placed in any of the four recesses shown and it will be understood of course that any number of recesses may be provided and thus the length of travel of the yoke 48 from its rearmost' position against the roller 32 forwardly, will be determined.-

The operation of the device is as follows: The length of strip desired is first set by positioning the pin 48. The thumb and forefinger are then inserted into the device on either side of the base member 42 so that when the thumb and forefinger grasp the tape and the yoke, the forefinger A contacts the tacky side of the tape and the thumb B contacts the yoke and the untreated or non-tacky side of the tape through aperture 44. The yoke and the web are now drawn for-. ward to the forward position illustrated in Figure 1 until the yoke 48 meets the pin 48 at which time the yoke can travel no further. The thumb B is now momentarily released as illustrated in Figure 2 and the yoke 48 under the influence of spring 42 moved backward against the guide roll 32, the drawn portion of th web remaining adhered to the forefinger A. The thumb is now placed back against the tape again and the tape drawn down as shown in Figure 2 against the cutting edge 48 where the delivered portion of tape is easily severed. The apparatus is now ready for delivery of a second piece, of tape by grasping the portion 42 of the yoke 48 as heretofore described.

It will be observed that the tape roller 32 constitutes an adhesion member to which the tape adheres near its end, while the machine is idle between successive operations. This adhesion roller thus supports the leading end of the tape and holds it in position adjacent to the base member or tape supporting plate 42 which supports the end of the tape ready to be grasped for the next dispensing operation. In the example of the invention shown the end of the tape is held so that its non-adhesive side is adjacent to the member 42, and such end projects beyond the adhesion roller 82 sufliciently to permit the end of the finger to be applied to the adhesive on such projecting end for drawing out the tape. It is furthermore to be observed that the finger is applied in a len thwise direction so that the end of the tape sticks to the finger lengthwise and in the leading end of the tape whereby tape may I line of the finger. when the tape is torn at it therefore projects endwise from the finger and is in the most convenient position for application to the package or other article upon which the tape is to be used.

While I have illustrated and described in detail certain forms of my invention, I do not wish to be understood as limiting myself to the use of such forms, as I realize that changes within the scope of the invention are possible, and I further intend each element or instrumentality recited in any of the following claims to be un-'- derstood to refer to all equivalent elements or instrumentalities for accomplishing substantially the same result in substantially the same or equivalent manner, it being my purpose to cover my invention broadly in whatever form its prlnciple may be utilized. 1
