Iif the element is formed so as to provide a cutting edge for severing the tape. The string 19' may be omitted but its use so that greater convenience results.

A further modification is shown in 6- 8.

. wherein the string l9 extendsunder the. outer layer 2|, just as in the form shown in Figs 1-3,7 but in Figs. 6-8 the free end'of string I9 carriesa tape cutting or severing device 29 having two downturned portions 30 and the upstanding serrated cutting edge portion 3|."

When the desired amount of tapehas been removed, the string, l9is again *placed underthe outer layer 2| ready for subsequent use. The cutting device 29 may be made 'of sheet metal or any other suitable material.

In the modification shown in; Figs. 9-10' the adhesive tape I6 is ,helically wound around the tubular member IS. A substantially ,U-shaped element "straddles the outer face of the'roll of tape with its side portions extending inwardly towards the center. of the member l5. Each side portion H has an inturned projection 42 extending into the end 'of tubular member I 5 so that the two projections 42 extend-towardseachpther and ber 15,. as clearly shown in Fig. 10. The-element 40 is preferably formed of sheet material and the Extending outwardly-from the part 43,'"which connects side portions 4| of element 40, is aprodimensions of the parts are 'suchthat the element 40 is mounted forrelatively free'movement around the outer faceor periphery of the roll,

jection 44 having a serrated cutting/edge 45. a f j r The element 40 ispositioned onthe roll or tape as shown in Fig. 9 so that the piece of tape 46.

v I broughtinto position as shown in Fig. 9, the tape which has been unrolled for use, may be severed v along cutting edge 45. f Since the inner face of the tape carries the adhesive or tacky'substancal it will be evident that after piece of tape 46 has.

been cut off, the adjacent portion 41 of-the tape on the roll will be adhesively secured: to'the face a v 3 comprising a tubular member about which the tape' iswound, a plate secu'red-toone end oiisaid;

of projection 44. .When it is again desired to use a piece of "tape from the roll, the element 40 is moved away from the end "so that its adhesive contact with prolection 44 is .broken 1 and the end 4'! of thetape renderedavallable so I that it may be grasped by. the hand to unroll the desired amount of tape. The element 40 is again severed'on edge and the endof the'tape' ad- 1 hesively secured to projection 44 ready for the .0 V i I o 5 I 4i! aifords not only a'cutting device for the tape but also providesa ready and convenient means for adhesively holding theend of the'tape sothat next use.' It will be apparent that the element it can be easilyrendered available when an i amount of tape is to be unrolled for use. 1

The modification shown similar to that shown in Figs. 1-3. except that ;'under the outer. layer of tape and. used in-the I in vthe structure of I am ableto attain the objects oifmy invention and provide simple yet eflicie'nt means for 1 in connection with a roll or spool of adhesive tape so that the outer endof the tape in, the roll may I be rendered" available. Great convenience will pie tape 'cuttingdevices whichj Ihave?provided. Eachu'form of my deviceis relatively simple in' v substantially parallel to the axis of tubular memble'cable'.-: I

. comprising a. member, aboutv which the" tapeyiis.

the outer end" of tapewhich has been adhesively 1 stantially at-the center of said plate, said string. extending under the outer layer of tape adjacent its; outer end and across andibeyond, theiface string'may be grasped and pulled so as to .withdraw the outer end of the tapel fromadhesivei; -cont'a'ct with the roll. w

instead of using a string for freeing theouter endi of the tape IS, a twisted, bendable wire 48 is em-' 'ployed.. The twisted wire is secured to plate ll. .5 on tube l5 by means of an eyelet member 4!,

which passes through a hole in the plate. ,i'I'he wire 48 is thus mounted for relatively free move ment relative to the plate and the roll of tape so that the end 50 01' the wire may be positioned same manner as string 19 Figs. 1-3.

From the foregoing it will be apparent that 1 thereby result to the"userj and further convenience will be afforded through the use of the sim- -structure so that it can. be cheaply andjreadily, 1. embodied in or attached to some of the rollson.
