SELECTIVE GUM'MED-TAPE-DISPENSING MACHINE.

Application filed November 28, 1925. Serial 10. 70,871.

My invention relates to machines for the dispensing of gummed tape, the ta e dispensed to be used in the wrapping packages and the like as a substitute for. cord or string, and has for its object the carrying within the frame of one or more widths of tape, power means for dispensing the same and selective means for dispensing the width of tape required for the package or article to be wrapped.

A further object of my machine consists in providing means within the machine for moistening the gummed surface of the tape, as the same is being dispensed.

A further object of my device, consists in providing a manipulating hand member adapted to complete an electric circuit, by the same being depressed selective means is provided for selecting the desired width of the tape to be dispensed, and when the circuit has been completely broken and the desired amount of tape having been dispensed, the return of the hand member to normal position, will automatically cut the tape dispensed through the action of the shearing blade carried on the lower end of the same.

A further object of my invention, consists in the arrangement of the parts in such a manner that the cutting of the tape ismade upon the unmoistened portion of the tape.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

Like reference characters refer to like parts throughout the several views.

1 is the base of the machine, having side wall frame .members2, disposed upon either side of the base and extendin practically vertical from the base. A sha t 3, is maintained within the side wall members 2, in suitable bearings and is held in position by thumb nuts 4 and 5, disposed on either end of the same. Mounted upon this shaft are one or more rolls of gummed paper, here shown as two in number, as shown at 6 and 7 the same being positioned upon the shaft by a spacer 8, which is secured to the wall structure of the machine by a suitable fastening means as a screw 9. Different sized spacers may be used to accommodate dif-v ferent width of rolls. The gummed paper is conducted from the roll through channel guideways or tubes 10 and 10', and passes etween the feed rolls 11 and 12 and 29 and 29. The lower feed rolls 11 and 29* are mounted on a rocking su port or yokes 11 and 29 respectively, w ich are rockabl mounted about shaft 13, secured to the sid e wall members of the machine. A power unit 14, as an electric motor, is mounted upon a base support 15, within the frame structure and is energized through an electric circuit, through the electric cords 16 and 17, which are connected to an outside source of electric energy.

When it is desired to secure gummed tape from the machine, the o eratin handle or knob 18, is lowered by t e han of the o orator. If it is desired to secure a wi e tape, the operating handle which is freely mounted on the sliding stand 24, is turned until the contacting arm 19, is made to engage with the trip 20*, which is normally held in raised position through the action of compression spring 21, su ported u on thebracket 22, at which time t e lower eed closing the electric circuit to the power unit 14, is then energized, turning the armature of the motor and the worm 26, WhlCh 1s se cured to the shaft thereof. The worm 26, engages the worm wheel 27 which is mounted on the shaft 27 A which is rotated thereby. The shaft 27 also carries thefeed rolls 29, and 12 which are rotated thereby, the roll 29 feeding the wider gummed tape from the roll 7. The side wall members 30 and 30 are positioned parallel to each other, and are spaced apart sufiiciently to permit the stem 24, to freely slide therebetween. The side wall members are each provided withiopenings of size and shape equal to the size and shape of the interior of the tubes 10 and 10 The lower end of the stem 24 1s broadened out into a rectangular plate 24", and the holes 28 and 28 are formed through. this plate. The lower edge of each of the holes 28 and 28 are formed at an angle to the horizontal as shown at 28 and 28 to form the cutting edges or knives of my devlce. The normal position of the stem'24, is such that the holes 28 and 28 are positioned above the tubes 10 and 10. In operation the knob 18 is depressed, which depresses the plate 24 so that the holes 28 and 28 will register with the tubes 10 and 10 and tape will pass through one or the other of the holes through the plate 24; and if the knob is released, the stem 24 and the plate 24 will rise to normal position, brou ht about by means of a spring 38, hereina ter described, the electric circuit to the motor 14 will be opened and the motor and machine stopped, and the paper strip passing through the machine will be cut by one or the other of the cutting edges or knives 28 and 28 as the case may be. The depression of the knob or handle 18, depresses the stem 24, also, and in doing so, the openings 28 and 28*, are made to register with the openings 10 and 10 through the side wall members 30 and 30 which form a guideway for the stem and which is best shown in Fig. 8. This permits the gummed tape to pass through the opening 28.

A liquid, as water, is contained within the basin 31, in which the wetting roll 32, rotates. The tape comes in contact with the wetted roller through the action of a holding down roller 33, disposed above the roller 32. The roller 32 is freely mounted upon the shaft 37, and rotation is imparted to it by engagement with the roller 33 which is rotated by means hereafter explained. The shaft 37 mounting the roll 33, is revolvably mounted to the outer ends of each of the arms 37 and 37 the inner ends of said arms being loosely mounted to the shaft 27. An engaging train of revolvable gears 34, 35, and 36 are mounted respectivel 1 to the shaft 27', to the arm 37 intermediate its ends, and to the shaft 37; and it will be seen that when the shaft 27 is rotated, shaft 37 with its associated roll 33 will also be rotated. The roll 33 normally rests upon and rotates the roll 32, and will rotate roll 32 when it, itself is rotated. The paper strip passes between the two rolls 33 and 32 when they are rotating, and as the strip passes between the rolls, the under or coated side of the paper will receive moisture from the wetting roll 32.

Moistened tape of the selected width will be dispensed through this train of movements and over the wetted roll until the desired length has been secured, at which time the operators hand is removed from "the knob 18, which permits the return of .the stem 24, which breaks the circuit and stops the motor on the upward movement of the stem, which is caused by the action of the compression spring disposed about the stem, as shown at 38. The spring 38 is compressed on the downward movement of the stem and which automatically returns the stem to normal position when the knob 18 is released.

Should it be desired to dispense the narrow gummed tape, the contacting arm 19, is moved to engage with the trip 2O as best shown in Fig. 5, at which time the same train of operations are set in motion,

with the exception that the hinged feed roll 11, disposed beneath the wide gummed tape to feed the same, is disengaged from r01 12, and thewide tape 7 is not drawn from the roll and upon the actuation of the machine the narrow tape 6 only is dispensed.

Should it be desirable to dispense both narrow and wide at the same operation, the same may be accomplished by the permitting of the contacting point 19, to be clepressed without contacting with either of the rolls at which time the same train of mechanisms will be set in operation, with the exception that both narrow and wide gummed tape will be dispensed to the re quired length, after which time the train of operations are stopped and the hand devices are permitted to return to normal position, at which time both narrow and the wide gummed tape are sheared off on the return of the hand device.

The hand device may be rotated within certain limits, the movement of which is governed by the stop pins or guides 40 and 41, disposed at either side of the same. To facilitate the engagement of the contacting arm 19, with either of the trips 20 and 20 emma the stop pins 40 or 41, and when depressed is positioned directl over the trip for dis engaging one of t e feed rolls. This is shown in the position of the contacting arm 19, engaging with the stop pin 40, in Fig. 4. The arm 19 being shown in dotted position.
