17 Claims. (Cl. 164-845) 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 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 and delivering at a point ready for use, the desired length oftape.
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 hand of the user while tape is being drawn by the other hand from the device. In general the mechanism includes a fixed mounting for a roll of tape and a pivotally mounted measuring element adapted to engage the non-tacky or untreated surface of the tape, to be grasped simultaneously with the leading end of the tape, and to be moved about its pivot in a direction away from the roll to draw tape from the roll 4for a predetermined udistance whereby a predetermined length oftape is drawn from the roll. Means are provided for releasing the pivoted element at the end of its arc of movement and for returning 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 length of tape delivered may be varied.
It is an object of the invention to provide a pocket size delivery apparatus for tacky tape particularly adapted for speedy and convenient serving of small strips of relatively narrow tacky material although it willbe of course understood that while the size of the construction isa 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 ap.
plied to the delivery of larger strips of wider web material. Further objects and advantages will appear from the following description and the drawing in which:
, MAR 191946 one side wall removed showing the tape dev livery 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, and
Figure 3 is a vertical longitudinal section taken on the line 43--3 of Figure 2.
Referring now to the drawing, the device includes an outside `casing I0 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 I8 is preferably formed of two inter'- locked frame members I2 and I4, 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 I6 which keys with the edge of the portion I4. The two case members are held together at the front portion of the machine by the lock post I8. 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.
'I'he portion I4 is provided with the inwardly extending b oss 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 26 with complementary bosses 28 and 30 which mount between them the tape guide roller 32. Similarly interiorly mounted bosses 34 and 36 carry pivot 38 upon which is pivotally mounted tape delivery element or yoke 40 which is normally spring pressed by spring 42 into the rearward position shown in Figure 2. As illustrated in Figure 3, the yoke 40 includes side members descending downwardly from the pivot 38 and a base member 42 which joins the-side members. The base 42 is preferably apertured as at 44 and also extends forwardly of the side members of the yoke terminating in a cutting edge Figure 1 is a side elevation of the device with 56 46 which may be serrated to facilitate cutting if desired.
The forward movement of' the yoke 4I) about the pivot 38 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 50 which may be cut through the walls as shown. The pin 48 may ever recess it is placed by the spring 52.
fit into the recesses between the teeth in the aperture 50 and will be held in position in what- 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 40' from its rearmost position against the roller 32 forwardly, will be determined.
The operation of the device is as follows: 'I-'he length of strip desired is-rst set by positioning the pin 48. The thumb and forenger are then inserted into the device on either side of the base member 42 so that when the thumb and forenger grasp the tape and the yoke, the forenger A contacts the tacky side of the tape and the thumb B contacts the yoke and the untreatedl or non-tacky side of the tape through aperture 44. The yoke and the web are now drawn forward to the forward position illustratedin Figure 1 until the yoke 40 meets the pin d8 at which time the yoke can travel no further. 'Ihe thumb B is now momentarily released as illustrated in Figure 2. and the yoke 40 under the influence of spring 42 moved backward against the guide roll 32, the drawn portion of the web remaining adhered to the forenger 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 46 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 d as heretofore described. l
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 y of such forms, as I realize that changes within recited in any of the following claims to be understood 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 principle may be utilized.
