Application Fb'ruary l9, 1947; Serial No. 729,593"

2'Glaims. (Cl. 74'144)' This-invention relatesto taper dispensing machinesran'd: is an improvement over the machine embodied'in mypr-ior Patent No; 2,406, 418; issued Augustfl'l, 1946', for Tape Dispensing Machines;

i Ani'object of this'inventionis to provide animproved means for actuating the feeding mechanism ofa; machine f this type so as to provide a-non-feeding cycle on the initial forward'stroke ofithey' operating: handle during which cycle the severing mechanism is returned:toits normal inoperative position.

Another object of this invention is to provide intazmachine oi thisi kirid a ratchet pinion carrier whichi-is fixed; relative to the drive shaft, the'car rierincluding aratchet pinion which is rotatably carriedibythe carrier, and a 'spring pressed dog which isrswingably carried by the carrier, the dog beingengaged by aifixed' stop on the return or backstrokeof the carrier so that the carrier'may haveffurther non-ratcheting movement and thepinion may rotateandmove with the carrier on the latte-r'or severing cycle 'ofthe drive shaft.

A further object of this invention is to provide in" a machine of this: kind-, an improved means for feedingwater: to the moistening element and for supporting the water bottle or reservoir.

A further object of this invention-is to providein combination a well, a tape moistening brush, and a bottle supporting bracketi fixed'to the well, the well and bracket being so constructed and arranged that when the water bottle is" in the brack et the weight of the *bottle'will tend to tilt the well and thereby maintainpressure from below on the tape through the brush.

With the above and other objects in view, myinvention consists. in the'arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed outin the appendedclaims.

In the drawings,

gure 5 is a fragmentary vertical section through the moistening means. 7 I Referringto the drawings, the-numeral !0 designates generally a housing or frame similar to the housing-or frame embodied-in my-prior'patent supra.

The housing or'fr'ame Ill includes a side wall I I and a tape feeding shaft I2 extends through the sidewall II and has secured to the outer end thereof a feeding gear I3. A drive or oscillatable shaft It is journale'd in the housing I0, extend ing' through the side wall-II and has loosely mounted thereon'a drive gear I5. The drive gear I5 is adapted to be rotated in one-direction only by clutch means'as will be hereinafter described.

Theshaft' I4 has fixed thereto a pair of -elongated plates I 6 and I I','the latter having a bushing' I8 which maybe secured'by means of a set screw I9 or other suitable fastening means to the shaft: I4; Thedriving gear I'5'is disposed loosely between the two'plates 'I'B'and' I! as more clearly shown in Fig-ure2l' The two plates I6 and I I have journaledtherebetween'aratchet or clutching-gearlllwhichis rotatablymounted on a shaft 2| extending between th'e' plates I6 and H.

In order to-provide'a means whereby the gear 20 may b'e'clutched' to the driving gear I5 upon rotation of: thedrive shaft M in a clockwise direction-as viewed 'in Figural, I' have provided a clutch gear lockingdog 22; The dog 22 is fixed between-a

pair ofkplates

23 and 24 which are pivotally mounted-onpivot'members 25 and 26 respectively; which are-secured to 'the plates I6 and I1 respectively:- at a point' outwardly from the axis of the shaft I4.

The dog-:22 is adapted tobe constantly urged to clutchingposition-by means of a spring 2'! which is connectedratone end to the outer plate 24 and is connected at the-'other-"endto the outer plate or gear carrier I'I; A'pin'28' is fixed between the outer ends of thetstwo piates 23 and'zll so as to cooperate with the-*dog'22 in holding these plates in spaced apart rela-tion and-loosely with respect to the pl'atesIG and I1.

When the gearcarri'enwhichcomprises the two 2 plates" lfi'and- H" is swung ina counterclockwise direction as viewedin Figurel; in'which direction the shaft I4' is rotating on its backward have furthencouriterclockwiserotation while thedog; 22 is" stopped in'its swinging movement with respect to the plates l6 and I1.

At the time; the dog*22 is stopped in its ratchetingf movementy-the dr-ive shaft Mxis operating on its tape severing cycle for severing the tape which has been previously fed forwardly on the clockwise rotation of the driving gear |5. When the drive shaft I4 is again rotated clockwise on the feeding cycle or stroke, the gear 20 will loosely roll over the feeding gear |5 during the forward swinging in a clockwise direction of the carrier comprising plates I6 and H. The two plates (6 and H are provided with elongated arcuate slots 30 and 3| respectively, through which the dog 22 is adapted to loosely and movably engage.

After the shaft 4 has been rotated on the for ward or feeding stroke thereof for a slight dis tance, the gear 2|! will move up to the stationary dog 22 and this dog will then lock gear with respect to the feeding gear l5. Further clockwise rotation of shaft l4 will cause gear l5 which is now locked to shaft l4 to rotate feeding gear |3. The dog 22 is so mounted with respect to the two gears l5 and 20, that when this dog is in clutching position with respect to gear 2|], the dog 22 will be locked between the teeth of the gear 20 and also the teeth of the gear l5, as shown in Figure 1.

By mounting the dog 22 as herein disclosed, this dog will not unduly wear the teeth of the ratchet gear 20 when the shaft I4 is rotating on its backward or idling stroke.

The machine ||l herein disclosed also includes an improved moistening means embodying an upwardly opening rectangular well generally designated as 32. The well 32 includes front and

rear walls

33 and 34, and opposite end walls 35 and 3B. A longitudinally extending rib 31 is carried by the bottom wall 38 and serves as a partition against which the inner end or back 39 of a tape moistening brush 40 is adapted to engage. The bristles 4| of the brush 40 are adapted to extend upwardly and forwardly, the bristles resting against the front wall 33 of the well 32 and contacting at their upper forward ends with a presser plate 42 of conventional construction. The tape is adapted to be moved between the lower side of the presser plate 42 and the ends of the bristles 4| for mois-' tening the gummed lower side of the tape as it is moved forwardly. The well 321 is adapted to be provided with water which will be disposed at a predetermined level as will be hereinafter described.

The side wall 35 has extending therefrom an L-shaped channel 43 which communicates with the interior of the well 32. A bottle supporting bracket 44 is fixed to the rear wall 45 of the channel 43 and includes a vertically disposed bar 46 which is secured by fastening members 41 to the rear wall 45. An acutely disposed bracket arm 48 extends upwardly and rearwardly from the lower end of the bar 46 and has fixed thereto a transverse arcuate bottle supporting saddle 49. The saddle 49 is formed at its lower end with an inwardly projecting stop member 50 against which the forward lower end of a water bottle 5| is adapted to engage.

The bottle 5| includes a cap 52 having extending therefrom a tube 53 which terminates within the channel 43 and the position of the lower end of the tube 53 with respect to the channel 43 will determine the height of the water within the well 32. The well 32 is adapted to removably engage on a pair of ledges 54 which are carried by the inner sides of the housing Ill. The housing I0 is formed with U -shaped cutouts 55 in the side walls thereof, within which the well 32 is adapted to removably engage. Preferably the well 32 loosely rests on the ledges 54 and is adapted to be slightly tilted due to the weight of the saddle 49 and the bottle 5| so that the bristles 4| will be under constant tension in order that they may frictionally contact the gummed side of the tape and this contact is maintained at all times by the tendency of the bottle 5| and the saddle 49 to tilt the forward end of the well 32 upwardly. In this manner the wearing down of the bristles 4| will be compensated by the upward tilting of the bristles under the weight of the bottle 5| and the saddle 49.

In the use and operation of this device, the oscillatable shaft l4 which is the drive shaft is rotated in a clockwise direction as viewed in Figure 1 to feed the tape forwardly past the moistening brush 40. The tape severing means associated with this feeding means is of such charactor as explained in my prior patent supra that the cutter is normally disposed across the path of movement of the tape when the drive shaft H is rotated reversely to the limit of its counterclockwise rotation. During the initial forward or clockwise rotation of the shaft l4, the driving gear 5 will be stationary due to the fact that the clutch gear 20 is rotating about the gear |5. When the gear 20 is rotated forwardly and upwardly during its lost motion cycle with respect to gear l5, this gear will then engage the locking dog 22. This dog is held stationary. by the swinging carrier comprising the two

plates

23 and 24 during the initial clockwise rotation of th shaft l4.

After the dog 22 looks the gear 20 with respect to the gear l5, as shown in Figure 3, the gear 2|! and the gear l5 will move as a unit and the gear I5 will be locked to shaft l4; At this time the feeding gear I3 will be rotated by rotation of the driving gear l5. On the return or idling stroke of the shaft I4, the dog 22 will ratchet with respect to the gear 20 so that this gear can freely roll over the periphery of the feeding gear l5 and the latter will be declutched with respect to the shaft I4.

I do not mean to confine myself to theexact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:
