Application January 18, 1952, Serial No. `267,030

4 Claims.

This invention relates to a device for dispensing building tape from a roll of the same, coating said tape during the dispensing thereof with a supply of cement, and shaping the tape for application to room corners or coves.

More particularly, the present invention has reference to an `improved dispenser of the type stated, wherein there is included a removable shaper attachment which can be taken out of the device whenever desired, for substitution of a different removable member so formed as to permit the tape to be dispensed in a hat condition.

The present invention, in this connection, constitutes a continuaticn-in-part of our copending patent application, Serial No. 244,523, filed August 31, 1951. In that application there was shown a coating dispenser for building ltapes so formed as to cause the tape to be dispensed fiat. This arrangement, of course, would be entirely satisfactory during the performance of most joint sealing operations, but would require that the tape be manually folded along its longitudinal center line prior to application thereof to a room corner or cove.

`The .main object of Ithe present invention, accordingly, is to provide a coating dispenser of the type illustrated and described in our copending application, but so formed as to permit the insertion of a shaping vattachment effective to fold vthe tape longitudinally during the dispensing thereof, whenever the tape is to be used at one of thefspecial room locations indicated.

A `fur-ther importan-t object is to provide'a coatn ing dispenser of the character stated which will permit substitution of the Shaper attachment with a maximum amount of speed and ease.

Yet another important object is to provide a coating dispenser as described which will be of simple formation involving comparatively few parts, but which will nevertheless be rugged and .capable kof use over a long period of time.

Other objects will appear from the following description, the claims appended thereto, and

`from lthe V,annexed drawing, in which like refer--V Referring tc the drawings .in detail,V theimproved coating dispenser formed in accordance with the present invention includes a flat, rectangular base Ii) having depending feet I2 at the several corners thereof. Fixedly mounted upon and extended longitudinally of the base are upstanding, parallel side walls I4. The side walls I4 are of raised formation at one end, and formed in the inner faces of the raised end 'portions of the side walls are vertical grooves I6 re ceiving the opposite ends of a shaftA or pin I8 on which a roll 29 of building tape is mounted. The roll 20 is rotatable upon and is disposed between the respective side walls I4, said side walls being in close spaced relation to the opposite side surfaces of the roll.

A flared hopper 22 is mounted upon the other ends of the side walls I4, and is formed open at its opposite ends. The hopper is removable from the position thereof illustrated in the several figures of the drawings, and to this end the hopper is provided at its lower end with angular mounting brackets 24 secured to opposite sides of the hopper and having depending flanges 26 supported upon and overlying the respective side walls I4.

Each flange 26 is formed, intermediate its ends, with a slot 28 opening upon the lower jedg'e of the flange. A wing nut 30 is threadable upon a bolt 32 extended through the slot of each iiange, the heads of the respective bolts A(seeV Figure 4) being received in recesses formed in the inner faces of the respective side walls I4, and the shanks of said bolts projecting through the respective slots 28.

It will be readily appreciated that this construction will permit the hopper 22 to be removed from the position thereof illustrated in the ldrawings whenever desired, for insertion or removal of the Shaper attachment.

The Shaper attachment has been generally designated 34, and is of box-like formation. Thus, the attachment constitutes a lower extension of the hopper 22, and to this end is formed with parallel, vertical side plates 34 so spaced apart as to cause them to lit snugly against the innerfaces of the respective side walls I4 when the attachment is positioned as in Figure 4. The side walls 36 of the attachment, as readily seen from Figure 3, are rigid with front and `rear walls 38 of the attachment, completing the box formation referred to above, and the front and `rear walls are extended beyond the side walls 36 to form tongues 4|) adapted to be received within complementary vertical grooves formed in the respective side walls I4 of the dispenser.

This construction is one which permits the attachment to be inserted between the side Walls I4 whenever desired, and the construction also permits the attachment to be removed from this location whenever it is desired that the building tape be dispensed in a flat condition.

Rigidly secured to the respective side walls 36 and front and rear Walls 38 is a bottom plate 42 having a pair of parallel grooves 44 formed in its upper surface, said grooves 44 being disposed in parallel relation and extending longitudinally of the base l0. f

A shaping rib 48 is xedly mounted upon the bottom plate 42, and has its opposite side edges aligned with the inner side edges of the respective grooves 44. The cross-sectional shape of the rib 48 is of importance, and as will be seen from Figure 4, said rib is formed cross-sectionally in the shape of an isosceles triangle with angularly disposed shaping` faces converging upwardly and intersecting at the longitudinal center line of the shaping rib. The shaping faces, it should be noted, are disposed at right angles to'one another, so as to shape the building tape exactly for the fitting thereof into a conventional room corner or cove.

Formed in the front and rear walls 33 of the attachment are 'angular slots, the upper edges of which are parallel to and are spaced closely above the shaping faces of the rib lit. The lower edges of the slots 4% are defined by the shaping faces of the rib, and thus, a length of building tape can be extended fully through the box-like attachment, said tape being passed through the respective slots t@ and being shaped within the attachment.

One end of the rib 4S terminates at the front wall of the attachment. The other end, however,

projects beyond the rear wall into the space delresult, the projecting end portion of the rib is increased progressively both in height and Wi th in the direction of said rear wall. The arrangement has been found to produce beneficial eiiects, in'that a length of building tape 52, when unw'rapped from the roll 2li, will be acted upon rst by the projecting end portion of the shaping rib, so `as to be gradually bent to shape without danger of its being torn during the operation.

A flexible rule 54 of conventional formation is preferably mounted adjacent one of the side walls i4 upon the base IB. so as to permit a measurement to be made of the tape 52 during the dispensing thereof:

Also, it is preferred that a cutting blade t be aixed to the front end of the base Ill, said blade being of triangular formation and being inclined upwardly (Figure 2). By reason of the particular formation of the cutting blade the length of tape 52 can be pulled downwardly thereagainst after a suitable amount of the tape has been drawn'through the shaper attachment, and out to the length selected.

At 58 we have illustrated an idler rolier journaled in and extending between the respective side walls I4, said roller being adapted to hold the tape against upward movementwithin the device, and being particularly eiective when the roll 2G becomes smaller.

It is of importance that the shaper attachment illustrated in Figure 5 can be removed from its operative position whenever desired, for substitution of another box-like member which would be formed identically thereto, with the exception of the shaping rib 43 and associated slots it. The boxdke member to be substituted, as will be appreciated, would be formed merely with a fiat botl tom plate, and with horizontal slots contiguous to the bottom plate and formed in the respective front and rear walls. A member so formed would permit the tape to be dispensed in a flat condition.

In use oi' the dispenser illustrated and described, asupply of cement, not shown, is deposited within the hopper 22, and will fill the box-like shaper attachment Thereafter, the tape is through the attachment, and will be coated with said cement while being,- simultaneously shaped to the desired cross-sectional congur tion. Y

it is believed apparent that the invention is not necessarily confined to the specific use or usesY thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention com prehends any minor changes in construction that may be permitted Within the scope of the appended claims.
