TAPE DISPENSING MACHINE Filed April 17, 1930 wuufi w m IUF W Patented Aug. 8, 1933 UNITED STATES PATENT, oRFicE-YJ f DISPENSING MACHINE V Louis'liinh New YOrnNQY. Ahpplication April 17, 1930. Serial No. 444,930 4 cl ims. (01. 271-44)- 'My invention relates to improvements in paper strip dispensers, andmoreparticularly, has referencegto and is illustrated in the accompanying, drawing in, its application to-a gummed or 4 adhesive paper strip dispenser device, such as is, adaptable foriclosingpaper packages and the like, andis an improvement on the dispenser disclosedin my co-pending patent application S. N. 396,999. V

Referring to the accompanying drawing, Fig. 1.illustrates inperspective, parts being broken away, a part of-a disriensingmachineshOwing an embodiment of my invention. .Fig. 2 is an enlarged. longitudinal sectional detail illustrating parts mounted upon the shaft. Fig. 3 illustrates part of the paper feed mechanism, partly in section, and parts broken away. Fig. 4 is a detail in perspective illustrating part of the strip forming and guiding mechanism. Fig. 5 illustrates, partly in section and'parts broken away, part of the finger control for operating the device. Fig. 6 is a View looking from right to left at Fig. 5, and Fig. 7 is a sectional detail of the water box and brush moistener mechanism.

8 indicates the frame of the machine, having a circular frame-like portion 9,. projectedlaterally therefrom, with a series of holes 10, for engagement by the pin 11, in the lever 12 for predetermining thelength of gummed strip to be torn off. Through the center of the frame is projected the spindle714, having rotatably mounted thereon at the outer end, .a lever 15, said lever having a counter weight 17, and being connected at the-top with another lever 18, by a pin 19, which pivotally retains the finger portion 20, for dispensing the strip.

The finger portion 20, pivotally mounted at 19, upon the two arms 15, 18, is provided with a deportion 24, that prevents rebound leftwardlyof r the lever 15, after it hasstruck the stop. This stop 23 is part of, or secured to the lever 12, which is mounted on the spindle 14,- as shown in Fig. 2, and which is preferably made of resilient material to permit the end 12 to be pulled ,serving as a, bearing forqthe lever 12, and for pending portion 21, which whenthe finger portoward you while shifting thesame around the ring 9 for changing engagement of the pin 11, with'the' holes '10 therein, thus shifting the stop 23, at any desiredpoint around (the circle and thereby varying the swing or stroke of the finger piece and lever 20, 15 respectively. 24' serves as an indicator or pointer, if desired, for indieating the lengthof strip to be cut.

Upon the shaft 141-issecure d ahous ing 25,"at

the right end of which is a reduced' portion '26 seating in the frame ,8. This housing is preferably secured to the frame 8 at three points with screws 27, and. has an internal circular chamber 28, within whichmay be lsecured the coiled flat spring 29 at one end, as indicated at- 30, the opposite end being secured at 31, to an oiT-set 32 from the 1ever'18, and at the'outer end of the shaft 14, is provided the ring 32, penetrated by the pin 16, for holding the combination referred to in proper relation upon the shaft 14; from all of which,,it' will be seen that by pulling the finger end 12' of the lever 12. toward the operator, the 'saidlever12 may be moved to the right or left, thus increasing or sea decreasing respectively, the sweep of the lever :89 7

l5, 18, which is pulled against the action of the spring 30, at the same time, the engaging edge 21 of the finger piece 20, gripping the periphery I of the disc 13 and rotating anticlockwise, the

roll of gummed strip within the machine, pass- .5

'B, C and Dshown somewhat diagrammatically in Fig. 3.; g

The free end 35 of the strip after passing between the rollers 33, 34, is raisedin the center by the tapered elevation piece 36, shown to ad- ;vantage in Fig. 4, thereby slightly channeling and stiffening the strip to insure proper rigidity of thestrip forfeedingofthe sameleftwardly, 7100 the cutting-01f mechanism'being preferably substan'tially'as shown in my co-pending case re-,-

The water-box for moistening the gummed stripbeneath, as it feeds out of the machine, is shown to advantage in Fig. '7, wherethe water level-is preferably as indicated' at 37, the bristles 38, of the brush extendingupwardly to contact with the under gummed surface of thestrip,

the brush is backed by an inwardly projecting portion 39 of the Water chamber 40, and is preferably at the base, with a metallic holder 41,

I for the'bristles, and projecting inwardly from the bottom of the chamber 4!}, is preferably provided a tongue or tongues 42, which snap the top edge of the metallic holder 41, thus hold ing the same properlyseated upon the base 43, and when it is required. to remove the brush, the bristles 38 are pressed back against the springlike support 39, thus moving the holder 41 free from engagement with the prongs 42, allowing the brush to be pulled upwardly and withdrawn.

Of course, it will be understood that various combination with said lever, a disc and means connected therewith: for feeding said strip whereby when said finger piece is operated and said 'levermoved, said disc is rotated, and an adjustable stop for controlling the length of throw of said lever. 2. In a strip feeding mechanism; a casing, a support therein for a strip of material to be fed, feed rollers engageable with the strips for feeding the strip from the machine, a spindle, an arm Ireely movable about said spindle as "and member in one direction, operative connections between the spindle and strip feeding means, spring means for rotating the arm in one direction, and adjustable means to limit said 7 an axis, a member fixed to said spindle, driving connections between said spindle and saidrollers, and pivoted finger engageable means on said arm engageable with the member fixed torthe spindle when the arm and pivoted means are moved in one direction. V

3. In a machine ofthe character described, a casing, a support therein for a strip to be fed, feeding means engageable with the strip to feed said strip, a spindle, an arm pivoted for free movement thereon, a member fixed on the spindle, a hand engageable member movably mountedon the arm and engageable with said memberon the spindle upon movement of the arm movement.

fl. In a strip feeding machine, a casing, a strip support therein, strip feeding means, a spindle, operative driving connections between'the spindle and feeding 'means, a member pivoted for .free movement about said spindle, a member fixed to the spindle, spring: means for swing- 0 ing the pivoted memberrin one direction, adjustable means for limiting said movement, a handle pivoted to said pivoted member and movable therewith, and means carried by the handle and engageable with the member fixed to the spindle 105 when said handle and pivoted member are swung ina directionjof movement opposite-to the spring actuated movement. r
