WILLIAM A. UTTZ, 83., OF ST. LOUIS, MISSOURI, ASSIGNOB TO PERFECTION PACKAGE SEALER COMPANY, INC., OF DALLAS, TEXAS, A CORPORATION OF TEXAS.

MOISTENER FOR GUMMED-TAPE MACHINES.

Application filed November 25, 1927. Serial No. 235,673.

As set forth in the patent the moistener used lary material supported with its lower end in atank of water while its other end projects adjacent the path of gummed tape drawn off or fed off from the machine. Such moisteners are preferably removable so that they can be renewed or cleaned.

One important object of the present invention is to provide'an improved general conmoistener for this purpose.

A second important object of the invention is to provide a brush like moistener with a novel form of holder which may be readily attached to and removed from the tank.

A third important object of the invention is to provide a holder for such moistener brushes stamped from a single piece of sheet material folded and bent to securely hold the moistener brush.

A fourth important object of the invention is to provide a novel form of moistener brush having a beveled end so that when the tape is moved in contact with such brush and the brush tends to bend the effect of such movement will be that only the ends of the bristles will be contacted by the tape, the brush .being different from a square brush which. when bent produces a wiping action with the sides of the bristles tending to remove the gum.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

'In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a front elevation of the holder with the brush inserted. therein.

Figure 2 is a rear elevation thereof.

Figure 3 is a side elevation thereof.

Figure 4 is a section on the line 4'4 of Figure 1.

Figure 5 is a detail view showing the blank from which the holder is formed.

In the construction of this meistener there ended is provided a blank which is stamped from a single piece of sheet material. 1

This blank has a body portionlO adjacent to be spaced from one end of this rectangular body portion there is at each side of the blank an arm 11, these arms being opposite each other. In forming the holder the longer end of the blank is bent on the lines 12 so as to provide a holder bottom 13, a front leg 14 and a rear leg 15, the holder thus being a U-shaped structure. The. short end 'of the blankis bent downwardly on the fold line 16 so as to provide a'hook or hanger 17 for engagement with an upturned lip L formed on the water tank T,- the holder being thus supportedin the tank. In order to prevent spreading of the legs 14 and 15 at their upper ends the arms 11 are made of such length so that they may be bent on the fold lines 18 at their 'unction with the back 15 and span the spacelietween the legs 14 and 15, their extremities being bent on the fold lines 19 to provide overlapping tabs 20 which lie against the outer or front face of the front leg 14.

The brush consists of a rectangular group of bristles 21 which have their lower ends bound by a rectangular metal ferrule 22, these lower ends being cemented in thel gferrule as indicated at 23. The upper end of this brush is beveled as at 24, the bevel being inclined upwardly from rear to front so that the brush has its short side facing the direction of the tape to be moistened and as the tape passes thereover in the direction of the arrow in Figure 4 and the bristles tend to bend forwardly the sides of the bristles will not wipe on the gummed surface but practically only the ends of such bristles will contact with the gummed surface. Moreover, this beveling insures a better contact between the wet brush and this gununed surface.

Obviously under this construction the holder may be lifted with the brush out of the tank with no trouble whatever and the tank and brush cleansed and reassembled.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departingfrom the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described,- but it is desired to include all such as properly come Within the scope claimed.

Having thus described the invention, What is claimed as new, is:

1. A moistener for gummed tape dispensing machines comprising a U-shaped holder, arms projecting from one leg of the holder and bent to engage over the remaining leg of the holder, a brush mounted in said holder and having a metallic band surrounding its lower end and forming a socket for the bristles of said brush, the upper end of the brush projecting above the holder, said brush being bevelled upwardly from rear to front.

2. A moistener for gummed tape dispensing machines comprising a U-shaped holder, arms projecting from one leg of the holder and bent to engage over the remaining leg of the holder, a downturned lip on one leg of the holder constituting a hanger therefore, a brush mounted in said holder and having a metallic band surrounding its lower end and forming a socket for the bristles of said brush, the upper end of the brush projecting above the holder, said brush being bevelled upwardly from rear to front.

3. A moistener for gummed tape dispensing machines consisting of a brush consisting of a mass of substantially parallel bristles, said brush having its bristles graduated in length transveisely of the brush and thereby having its working edge beveled transversely of its length, said brush thus having a short side and a long side, and means to support the brush with the short side facing the direction of the tape to be moistened.

4. A moistening brush for gunnned tape dispensing-machines comprising a multiplicity of bristles arranged side by side to form a mass rectangular in cross section, said mass being adapted to have one cross sectional dimension in the direction of movement of gummed tape through the machine, the bristles being graduated in length to form an even bevel in the direction of said dimension with the shorter bristles toward the direc tion from which the tape moves, said brush being adapted to have the tape engage evenly on the extreme points of all the bristles in movement over the brush.

In testimony whereof I atlix my signature.

WILLIAM A. U'r'rz, SR.
