9 Claims. (Cl. 164-47) This invention relates to spools of tape of various kinds and classes. More particularly, the invention deals with a dispenser inV the 'form of a casing in which the spool is adapted to be arranged. the casing having a spring actuated cutter mounted thereon to facilitate severing of a withdrawn length of the tape, and at the same time, rendering a tape end accessible for withdrawal of additional tape as and when required. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the viewsand in which:

Fig. l is a perspective view showing one of my improved devices arranged upon a tape spool; and

Fig. 2 is a section substantially on the line 2-2 of Fig. 1, showing only a part of the construction and with parts in different position in full lines `and in the position shown in Fig. 1 in dotted lines.

In Fig. l of the drawing I have shown at I0 a spool of adhesive or other tape, a tape end being shown at II in said figure. At I2 is shown a cup or disk-shaped casing in which the spool I is mounted, the casing having atl one edge av slot or opening I3 facilitating the threading of the tape into an aperture Il formed in the peripheral wall of the casing I2. The slit I3 is preferably positioned at a point forwardly of a. cutter I5 when the cutter is in retracted position,` as shown in full lines in Fig. 2 of the drawing. The casing I2 at one side of the aperture I 4 is provided with a i'ingerpiece opening I8 spaced from the aperture I4 by a transverse strip I1 which forms a platform upon which the adhesive side of the tape II is temporarily secured after a tape end has been severed, as later described,

Secured to the casing I2 at the other side of the aperture Il isa plate I8 having at one end a raised ear or lug I9, and at the other end an outwardly pressed stop portion 20. The plate is provided with an elongated opening 2| centrally and longitudinally thereof. Slidably mountedin the plate I8 and on the periphery of the casing I2 is the curved cutter I5, the curvature of which conforms to the curvature ofthe casing. The cutter I5 has at its inner end an outwardly extending lug or iingerpiece 22 to which is secured a pin 23 upon which one end of a coil spring 2l is mounted. The other end of the spring is secured in any manner to the lug It. The spring 24 is tensioned to normally 2 support the cutter I I lin the ull line position shown in Fig. 1, and the dotted line position shown in Fig. 2. The other end 'of the cutter I5 has an enlarged blade portion 25 having a sawtooth cutter edge 2B which is greater in width than the width of the aperture I4 and opening I6, so that the enlarged end 25 freely slides over the casing and is guided by the walls of the casing.

In the normal position of the cutter IB, the edge 26 is disposed at-a point beyond the crosspiece or platform I1 and over the finger openingl I6, as clearly seen in dotted lines in Fig. 2 ofthe drawing. It will thus beapparent that when the cutter is retracted to the full line position of Fig. 2, the end 21 of the tape is disposed over the opening I6 and may be freely grasped by the fingers of a hand, to pull the tape outwardly first in removal from the platform I'I and then to withdraw the tape from the spool, as is indicated in dot and dash lines at 28 in Fig. 2.

When the required length olfy tape has been withdrawn. with the cutter retained in the retracted position by the thumb engaging the finspooldiameters, as well as tape widths.

gerplece 22 and a finger engaging the lug I9, the iingerpiece 22 is released, and4 the spring will advance the cutter forwardly. Upon completion of this operation, the tape will be partially severed by the cutter edge 26 and can be readilytorn olf.

In the above operation, the withdrawn tape is held taut to enable the vcutter edge to at least partially penetrate the tape.

With some types and kind of tapes, the cutter may actually sever the tape in the aforesaid movement. It will also be understood that the cutter automatically folds the tape upon the platform I1, thus again securing the same thereto and leaving another tape end 21 exposedv for engagement by the fingers of a hand when it is desired to withdraw another length of tape.

In the accompanying drawing, the plate I8 is shown as secured to the casing I2 by rivets, as at 29, but any form of fastening can be employed. It will be understood that the offset portion 20 serves to guide the shank 30 of the cutter in its movement on the casing and the cutter is further guided by the lug or fingerpiece 22 operating in the aperture 2I. It will lalso be apparent that the casing I2 will be constructed to suit spools of various kinds of tape which are of standard sizes, In referring to sizes, reference is had to When the tape of one spool has been consumed. a new spool may be inserted in the casing.
