- This invention relates to dispe ing machines for gummed tape, and more parti' ularly to machines of the type in which the leading end of thetape is seized by the operator and pulled for- Ward to draw the tape across a moistening device.

It is a primary object of the present invention to provide means in a machine of this type H which will avoid the necessity: of the operator's l0. putting his thumb or fingers upon moist, gummed \portions of the tape, which 'will nevertheless "moisten the tape in such a *manner that the whole severed strip adheres to the package on which it is placed\after severance, and which 5 will facilitate the seizing of'the leading end of the tape by the operator.

To this end'it is a feature of the invention that provision is made of a tape moistener, a tape severing means normally adjacent to the mois- 20 tener in position to separate the wet tape from the dry tape but moveabie in anti-tape feeding direction by the same fingers of the operator with which he grasps the-leading end of the dry tape, and of means for causing the exposed dry end of the tape to be deflected into such position relative to the operators fingers that he can grasp the tape by thereafter moving only his thumb, and in such a position that whenpthe operator allows the knife to return to its normal 30 severing position without causing any relative movement between knife, fingers, thumb and tape, the thumb will pass over the moistening element without touching it, and the fingers will be pressing a portion of the tape firmly against the moistening brush.

Thus a tape zone containing an excess of moisture is provided between the dry end and the normally moistened length of the tape. The zone of excess moisture supplies moisture enabling thedry end to be moistened and struck down as an incident of applying and pressing the tape against a package.

Other objects and advantages will hereinafter appear.

' The dispensing machine comprises a frame i which forms at the rear end thereof a receptacle for receiving a roll 2 of gummed tape. The receptacle is provided with a hinged cover 3 so that access may be had to the interior of the receptacle as required. The cover is adapted to be swung baclr to the dot and dash line position indicated at 3a in Fig. 1. An arm ti sup ported upon a pivot pin ti carries at its forward end a bar t having a presser strip i of felt or other suitable friction material mounted thereon. The felt presser strip 7! bears against a lip t by gravity and presses the tape 9 against the lip,

- thereby applying a light frictional resistance to the drawing forward of the tape, so that the tape is held taut when pulled forward, and is restrained against retrograde movement at other times.

An inverted bristle brush i ii is set in a reservoir or tank ii at the forward end of the frame i, the butt of the brush being submerged in water. The brush is supported between the rear wall it ,of the reservoir i i and aremovable cover plate itof the reservoir; The tape is intended to be drawn from the roll 2 between the lip 8 and the presser foot i, and across the tip of the brush iii.

Between the lip 8 and the brush i U provision is made of -a tape severing and tape deflecting device it. The device it comprises arms i5 pivotaliy mounted upon a cross pin it. Upon the upper ends of the arms l5 there is fixedly mounted a tear-01f blade andtape tensioning device H and an opposed guide plate it! which jointly form a. guide throat throughwhich the tape 9 passes toward the brush in a plane substantially below the tops of the bristles and ap- I proximately at right angles to the direction of spring 20 which is secured at one end to the machine frame and at the opposite end toa pin 2| mounted on the 'tail portion of the arm l5. A plate 22 carried by rocker arms 23 is pivotally-supported upon the arm libeneath plate I! upon a cross pin or shaft 24. The plate 22 carries a weight 25 which normally urges the plate to its lower position as indicated in Fig. 1. The plate 22 ,is provided at its forward end with an upturned deflecting lip 26 which is located far enough forward to stand a little clear of the forward ends of the 'platesl'l and l8 when the plate 22 is swung counter-clockwise relative to them.

At the conclusion of any operation the parts remain in the positionshown in Fig. 1 with the forward. end of the tape substantially flush with the forward edges of the plate l1.

' and dash lines in Fig. 4. V

draws the tape into. engagement with the brush bristles-as shown i'n Fig. 5, the arm and the when the operator desires to draw a strip of tape from the machine he places his hand in substantially the position illustrated in Fig. 1 so that one or more of his fingers bear against the plate I! in a position to thrust it rearward. The operator thrusts the plate rearward as illustrated at successive stages by Figs. 3 and 4. This carries the arm l5 counter-clockwise and the arm carries with it the deflector lip, 26 and the supporting arms 23 thereof. During this movement the tape 9 is restrained against retrograde movement by the lip 8 and the opposed presser strip 1 so that the tear-off blade l1 and the plate I8 move rearward relative to the. tape, causing a leading end of the tape to be exposed inadvance' of said blade-and plate. The plate l8 serves as a guide to hold the tape above and clear of the lip 26, so that thelip does not engage nor ob-' struct the leading end of the tape;

The rearward swinging of the arm 25 carries the tail portions of the supporting arms 23 .against an abutment lip 21 formed on the frame.

Continued rearward movement of the plate I! and the arms l5 causes the plate 22 to swing, counter-clockwise'relative to the arms l5. As shown in'Fig. 4, this-movement causes the lip 1 or flange 25 to swing up across the forward'ends of the plates l1 and. |8"and to momentarilycurve or deflect the leading end2l of the tape 1 ,upward to a position like that shown in Fig. 4.

The operator now moves his thumb to grip the tape against his foreflnger as illustrated in dot The operator then parts carried thereby being meanwhilereturned to their normal positions. The. operator now draws the desired length of tape across the brush and tears it off against the tear-off blade H.

The torn of! length of tape 28 is then applied to a package ,29 to seal .the V ageI- It will be observed that "a portioniiil of' the deflected tape'end never comes 'in contact with the brush and istherefore dry, evenafter the tape has been torn ofl.- There is a zone 3| of the tape, however. adjacent this dry end (the is made enough stronger I cause the parts to remain normally in the posiwrapper of the-packportion shown in contact with the brush, Fig. 5) which is moistened excessively by reason of the fact that the arrangement of parts causes the fingers of the operator to press this portion 3| directly against the brush. The later moistened portions of the strip are brought into a lighter contact with the brush due to tautness produced by the pull of the operator's hand from in front, and to the tensioning or dragging effect of passing. the tape at a sharp (approximately angle around the cutter edge |'l.- When the tape has been laid on the package, therefore, in the manner shown inFlg. 6, the operator in smoothing it down may draw his hand from left to right across the successive zones 3| and 30. This causes the excess moisture on the zone 3| to be spread underneath the zone'30 so that the zone.

10 is thus moistened and sticks to the package even though it was dry when it left the dispensing device.

In Fig. 8 the tape is drawn from a source of supply (not shown) over a support to and beneath a gravity operated presser la to a moistening brush Illa. So far as-the operator is concerned the mode of operation is the same as that of the embodiment disclosed in Figs. 1 to 5 and 7. Thetape severing and tape deflecting means is different, however, in construction.

A tear-off blade 30 having an up-turned, finger engaging, operating abutment 3| is carried at the upper ends of arms 32 which are pivotally mounted upon a pin 33. A spring 34 urges (the blade 3|! toward its normal position adjacent the moistener. A tape deflecting orbending plate 35 is pivotally mounted upon a pin 36.v The pin 36 is supported on ears 31. A spring 38 urges the bending plate 35 counter-clockwise. An end portion of the tear-off blade, however, engages a flange of the-bending plate 35 and the spring 34 than the spring- 38 to tion shown in full line in Fig. 8; The flange on the plate 35 is located outside the lateral bounds of the tape I the. blade 30a, so that the tape is caused to pass freely between the blade and the plate.

when the operator places his flngers agains the finger piece 3| of the'blade 30 and pushes it rearward the blade is swung to the dot and dash line position indicated at 390 in Fig. 8. The bending plate 35 follows the tear-oi! blade to the dot. and dash line position 35a of Fig. 8, bending the leadingend of the tape upward to. a position adpath and spaces the plate 35 from jacent the fingers which were used for pushing the blade rearward, so that the operator can grip the tape merely by moving his thumb toward these fingers. By placing the thumb against the upper end of the deflected tape so that the tip 'of the thumb stands above the finger tips, the

thumb may be properly located so as to escapeengagement with the brush although the flnger tips are caused to press the tape firmly against the brush. The operator is influenced by the mechanism to move his thumb and fingers in from-a source of supply around a-rol1er 40 andthence between rollers 4| and 42 which are mounted in the machine frame. A tear-oif blade 43 having an operating finger piece 44 is mounted at the upper ends of swinging arms 45. A spring 1 46 connected to one of the arms 45 and to the machinezframe normally holdsthe blade 43 fortear-ofi blade 43 isthrust rearward the tape isrestrained from moving rearward with it by the roller 4| and hence the leading end'of the tape is exposed by such rearward movement of the blade. When the blade has moved to the rear of the roller 4? as shown in dot and dash lines in Fig. '9 the tape springs upward to the vertical position illustrated in Fig. 9, closely adjacent the fingers which the operator is using for moving the blade. Theoperator then moveshis thumb toward these fingers in the manner already described to grip the tape, and draws the tape forward, the thumb passing clear of the brush but the fingers pressing the tape firmly against the brush.

While I have illustrated and described in detail certain preferred formsof my invention, it is to be understood that changes may be made therein and the invention embodied in other structures. 1' do not, therefore, desire to limit myself to the specific constructions illustrated, but intend to cover my invention broadly in whatever form its principle may be utilized.
