Referring to anillustrative embodiment of the invention in greater detail with particular reference with: drawings, side plates 10 and 11 are mounted on opposite sides of a bridge 12 carrying a protruding stop 13. Lugs Ma, 1% and 11a, 11b are respectively formed on the extremities of the lower edges of the plates 10 and 11, Also joining the side plates 10 and 11 is a blade mounting pin 14deformed by a rib 15 extending longitudinally thereof. V g t I Flanges 1 6 and 17 extend inwardly from .the forward upper portions of the side plates 10 and 11, respectively. Formed on the flangesv 16 ,and 17, are triangularly shaped surfaces ldand 19 sloping obliquely from the interior towards the plates 1! and 11, respectively. Flat lower snubbing surfaces 20 and 21. are found. under the flanges 16 and 17, respectively, these surfaces being shaped and positioned tov cooperate with a snubbjing and cutting blade indicated generally, at .22.

The, blade 22 is formed at the left hand. extremity thereof, as shown inFigure 7, with a cutting edge 23 and at the right hand extremity with a snubbing surface 24 formed by rolling a portion thereof, A short distance to the rear of the cutting edge 23 on the blade .22 are found a pair of surfaces 25 and 26 angularly positioned toucooperate with the surfaces 18 and 19, respectively. As may be clearly seen from FiguresS and 6, the blade is formed with a curved channel 2'7, this construction, permitting the blade 22 to be snapped on the pin 14. Reverse bends 28 and 29 in the form of loops are also formed adjacent to the channel 27 to add resilience to the blade 22. N

A tape 39, coated on its upper surface, is passed from a roll 31 under the snubbing surfaces 20 and 21 and selectively extends upwardly against the positioning surfaces 18 and 19 (Figure 5) or outwardly in contact with the blade 22 (Figure 6). 7 V

The blade 22 is formed in such a fashion that the snubbing surface 24 is adapted to engage and press the adhesive coated tape 30 against the snubbingsurfaceslt) and 21 in order to snub the tape 30 and prevent it from being withdrawn from the roll 31 while it is being severed, as illustrated in Figure 6. q

Initially the tape 30 is in the position shown inFigure 5 with its-free end 32 extending upwardly and with the blade surfaces "25 and 26 urgingit against the surfaces 18 and 19. ihe tapeml may be' mean any suitable ,ontype blade 22 in the tape holder and dispenser. particular .type, composition and gauge of the tape used the stop 13, the resilient loops ZS'and 29 permitting a substantial movement thereof. Further downward pressure cuts the tape 3il'on the cutting edge 23. g

Immediately after the tape 36 has been severed, the

blade22 will be releasedand spring upwardly about the pin 14. As the surfaces 25 and 26 approach the surfaces 18 and 19, the rib 15 on the pin 14 will tend to spread the channel 27 due' to its configuration (Figure 5). Thus,"the inner wall of the channel 27 will be in tension on the shaft 14 and the rib and the blade 22 will be held in place against the surfaces 18 and 19. As mentioned above, these surfaces are oriented to impart to r the free end 32 of the tape a curved configuration to hold it rigidly in position. v r

A number of advantages are obtained by using a snap- The determines the characteristics of the blade 22. .Thus,

the sharpness of the pointed edge 23 and the resilience and hardness of the blade must be considered in choosing a' blade for particulartapes to make certain the tape will be cleanly severed and the blade returned to the position shown in Figure 5. With certain stretchable tapes such,

for example, as one of the new polyesters known as Mylar, it may be adavntageous' to provide a protuberance on the point of the edge 23 as shown in applicants copeuding application Serial No. 396,144, filed Decemher 4, 1953, now Patent No. 2,805,714, issued September 10, 1957. With the employment of the snap-on type blade, the blade best suited to a particular tape being used may be easily andquickly snapped into place on the cutting unit.

Respectively formed on the upper edges of the side plates10 and 11 rearwardly of the flanges 16 and 17 are a pair of ears 33 and 34 serving to prevent the free end 32 from being folded back and contacting the lead of the tape 39 between the roll 31 and the flanges 16 and 17. These ears also function to secure a cover on the tape holder and dispenser as will be described hereinafter.

Formed on the upper portion of the side plates 10 and 11 is a hub indicated generally at 35 for supporting the roll .of tape 31. The hub 35 is formed from a pair of circular pieces 36 and 37 extending obliquely rearwardly from inwardly extending flanges 38 and 39, preferably formed integrally with the rear edges of the side plates 10 and 11, respectively. The pieces 36 and 37 abut each other; at their rear extremities and have formed thereon outwardly and rearwardly extending keying lugs 40 and 41,re'spectively. As may be clearly understood by referring to Figure 2, to mount the roll 31 on the hub 35 it is merely'necessary to insert a finger on one hand in the gap between the pieces 36 and 37 to flex the side plates 10 and 11 outwardly and subsequently to insert the roll in thethus widened gap with the other hand.

After mounting the roll of tape 31 on the hub 35, the free end 32 of the tape may be withdrawn and then twisted or folded to permit it to be passed between the flanges 16 and 17. Thus, due to the spaced positioning continuity in the floor thereof at the point 44. Upwardly extending circularly shaped portions and 46 may be formed on the upper surface of the base 42 on both sides of the recess 43.

Disposed on both interior vertical walls of the recess 43 and extending to the portions 45 and 46 are a pair of locking bosses 47 and 48 shaped to secure the remaining elements of the dispenser in operative position as will be apparent from the following discussion. Forward edges 49 and 50 of the bosses 47 and 48, respectively, extend in a straight line slanted rearwardly from the floor of the recess 43 to the portions 45 and 46, respectively. Inaddition, rear edges 51 and 52 of the bosses 47 and 48, respectively, each contain a substantially vertical lower edge and a rearwardly slanting upper edge,,the upper edges preferably being substantially parallel to the forward edges 49and 50..

Formed on the floor of the upwardly extending forward portion of the recess 43 is a spreader lug 53 protruding upwardly and havingits sides 54 and 55 bowed outwardly (Figures 9 and 11). i

A rubber pad 62. on the bottom of the base 42 serves to protect the finish of the surface supporting the tape holder and dispenser.

In assembling the desk type tape holder and dispenser, the holding and serving unit including the roll of tape 31 is inserted into the recess 43 with the rear straight edges of the side plates 10 and 11 contacting the edges 49 and 50 of the bosses 47 and 48, respectively, and the lugs 10a and 11a abutting the point 44. It will be noted that the lugs 10b and 1112 will hang over the-forward'lip of the recess 43, The forward edges of the keying lugs 40 and 41 will at the same time engage the upper edges of the rear edges 51 and 52 of the bosses 47 and 48. In addition, the spreader lug 53 will engage the interior surfaces of the side plates. 10 and 11 and bow them outwardly by virtue of the surfaces 54 and 55 to provide tional holding force there'between.

In pulling the tape 30 from the roll 31, the longitudinal force exerted will'be carried by the bosses 47 and 48 through thekeying lugs 40 and 41. On the other hand, urging'the tape 30 downwardly against the cutter blade 22 forces the rear edges of the plates 10 and 11 against'the front edges 49 and 50 of the bosses 47 and 48. In addition, in the event the entire holder is turned upside down, the spreader lug 53 will function to retain the tape cutting,

a holding and positioning unit in its operative position in the base 42. r

If desired, a cover 56 may be provided to enclose the roll of tape 31. Formed on the cover 56 is a head 57 adapted to engagethe base 42 as will be explained hereinafter. Centering tongues 58 and 59 extend from the lower side of the cover 56 while a flange 60 is formed on the forward edge thereof. A small protrusion 61 is centered on the cover 56 slightly to the rear of the flange 60.

In assembling the cover with the remaining elements of the tape holder, the flange 60 is snapped under the ears 33 and 34 and the centering tongues 58 and 59 are inserted between the rear edges of the plates 10 and 11 and the forward edges of the keying lugs 40 and 41. It will be apparent from Figures 8 and 10 that the head 57 will then engage the upper surface of the, base 42 including the edges of the portions 45 and-46. The protrusion 61 functions to prevent the'free end 32 of the tape 30 from adhering to the flat upper surface of 'the cover 56 thus making it simple to remove it therefrom after the device has been removed from its package, for example.

. It will be understood that the above described embodiments of the invention are illustrative only and modifications thereof will occur to those skilled in the art.
