WARREN DUBROFF BY United States Patent O 3,297.51!) PORTABLE TAPE DISPENSER Warren Du Broif, 550 Carel Court, Highland Park, Iii. 60635 Fiied Mar. 5, 1964, Ser. No. 349,69) 11 Claims. (Cl. 156-357) This invention relates to a portable tape dispenser, and, more particularly, to a device for dispensing gummed tape for use in closing cartons, and the like.
A variety of devices, for the most part complex, have been provided in the art for taping closed paperboard cartons as the same issue from a filling line, or the like. In order to insure reliability of the taped closure, there must be adequate moistening means for the gummed tape, and this has resulted in reservoirs and other types of wetting means that limit the versatility of the device for accommodating cartons of different sizes. In particular, the previously employed water reservoirs have prevented the devices from being truly portably, i.e., usable in a variety of positions-vertically, horizontally, etc.
In general, it is an object of this invention to provide a novel gummed tape dispenser. More particularly, it is an object to provide a portable tape dispenser. Other objects and advantages of the invention may be seen in the details of construction and operation set down in the following specification.
The invention is explained in conjunction with an illustrative embodiment in the accompanying drawing, in which:
FIG. 1 is a perspective elevational View of the inventive device;
FIG. 2 is another perspective View, but from the other sideas compared to FIG. l;
FIG. 3 is a schematic elevational view similar to FIG. l and showing the parts in one condition of operation;
FIG. 4 is a View similar to FIG. 3, being schematic, but showing the parts in the condition in which they are disposed during application of the tape;
FIG. 5 is an enlarged sectional view of the device of FIGS. l and 2 such as would be seen along the sight line 5.5 of FIG. 6, whereby the showing in FIG. 5 is partially in section;
FIG. 6 is a vertical sectional view taken along the line 6 6 of FIG. 5;
FIG. 7 is an enlarged sectional view of the lower righthand corner portion of FIG. 6;
FIG. 8 is fragmentary sectional view taken along the line 8 8 of FIG. 7;
FIG. 9 is a view similar to FIG. 8 ybut showing the parts in a different operational condition;
FIG. 10 is an enlarged fragmentary perspective view, partially in exploded form, of a portion of the apparatus of FIGS. 1 and 2;
FIG. 11 is an enlarged sectional view taken along the line 11--11 of FIG. 10;
FIG. l2 is an exploded perspective View of a portion of the apparatus of FIG. 5 and which is designated by the numeral 12 therein; and
FIG. 13 is a fragmentary sectional view taken along the line 13-13 as applied to FIG. 5.
In the illustration given and with particular reference to FIG. 2, the numeral 26 designates generally a frame, which is seen to be relatively elongated and U-shaped in transverse section. The frame 29 is defined by sides 21 and 22 which upstand from a bottom wall 23, the bottom wall 23 being centrally apertured as at 23a (see FIG. 5).
At one end, the frame 20, more particularly the upper portions of the Vwalls 21 and 22, is equipped with slots 24 accommodating a shaft 25. The shaft 25 carries a roll of tape 26 which is applied by being threaded through a path 3,297,5I Patented Jan. 10, 1967 lCC under a friction wheel 27 over a moisture roll 2S and under -a pressure roller 29. As can be best appreciated from FIG. 5, the moisture roll 28 is supplied with water from a reservoir 30 mounted on a superstructure generally designate-d 31 extending above the frame 20.
The step of tape application can be readily app-reciated from a consideration of FIG. 4, wherein the frame 20 is tilted relative to the application surface 32. The pressure roller 29 is forced upwardly in the direction of the arrow provided thereon in FIG. 4 so as to pivot about a pivot point 33. This releases clamping pressure as at 34 on a iiexiblc conduit 35 so as to permit gravity fiow of water from the reservoir 3&1 to the moisture-applying roll 2S. As the tape adheres to the surface 32, movement of the frame 20 to the left under the grasp of handle 36 causes more tape to unwind from the roll 34. This opera-tion is continued until sufficient tape has been laid down, whereupon a cut-off knife 37 is energized (see particularly FIG. l0) to sever the tape, as is indicated in FIG. 5.
Returning now to FIG. l, it is seen that the path of the tane T in being unwound from the roll 26 causes it to iirst pass under the friction Wheel 27, which is equipped With a knurled surface as at 27a (designated only in FIG. 5). The friction wheel 27 is fixed to a cross shaft 38 which is ournaled in openings in the frame sides 21 and 22 as at 39 in FIG. 1. The shaft 38 is equipped at one end with a manipulating knob as at 40 in FIG. 2, permitting the same to le turned, whereby the friction wheel 27 feeds tape over the moisture-applying roll 28 and toward the pressure roller 29. This occurs after the tape has been severed by the knife 37 and .preparatory to laying down another strip ofthe tape T on the surface 32.
Also mounted on the shaft 38 is a sprocket 41, about which is entrained a bead-type chain 42 (still refer-ring to FIG. 2). The chain 42 is entrained about a second and smaller sprocket 43 which is provided as part of the cross shaft 44 in which the moisture-applyin g roll 28 is mounted. This can be seen in enlarged scale in FIG. 13, wherein the roll 28 is seen to be constructed of absorbent rubber material and fixed about the hollow shaft 44 for rotation therewith. At one end, the shaft 44 is coupled to the conduit 35 as by a suitable fitting 45. The shaft 44 is apertured as at 44a so as to permit fiow of water from the conduit 35 out of the hollow shaft 44 and into the sponge-like roll 28. The roll 28 rotates faster than the wheel 27 to develop an advantageous wiping action on the tape T.
The shaft 44 is journaled in water-tight relation within the extension of the fitting 45 as at 46, and on the other side is journaled within a suitable bearing 47 provided within the wall 21.
The superstructure 31 is provided with a spring-loaded guide member as at 4S (see particularly FIGS. 1 and 5) for urging the tape T against the moisture-applying roll 2S. For this purpose, a cross shaft 49 is mounted in the superstructure 31 and equipped with a spring 50 to extend between the side members 51 and 52 which are joined, respectively, to the sides 21 and 22 as by bolts 53 (compare FIGS. 5 and 6). The guide 4S is equipped with a concave lower end portion as at 48a for developing a line-type bearing against the surface of the moistureapplying roll 28.
The ysuperstructure 31 also provides a connection for the handle 36, and for this purpose the side members 51 and 52 are angled inwardly relative to each other, as can be seen in FIG. 6, to define a support for the tubular sleeve 54 shown in dotted line at the extreme upper lefthand portion of FIG. l0. For this purpose, the side members 51 and 52 may be `welded to the sleeve 54, which also provides a convenient mounting means for a ring generally designated 55V in which the tubular reser- Voir 30 is mounted. Extending rearwardly from the 3 sleeve 54 is the handle 36, which may be advantageously equipped with a bicycle grip, as illustrated particularly in FIGS. l, 2 and 5.
The sleeve 54 also provides a pivotal mounting for a latch member 56 which is seen to be4 equipped with a laterally-extending trip or depressible part as at 57 in FIG. l0. At its lower portion, the latch member 56 is notched as at 56a and receives a lug 58 constituting part of the knife 37.
The knife 37 (still referring to FIG. l0) is springloaded as by spring 59 on a longitudinally-extending shaft 6i), whereby the knife is urged downwardly to coact with a lower knife edge 61 and thereby sever the tape in the fashion indicated in FIG. 5 wherein the knife 37 is seen in contacting relation with an anvil 61. The loading of the spring 59 is achieved by means of rotating the collar 62 (see FIG. l) after the locking pin 63 has been temporarily retracted while still being supported within the cap 64 of the shaft 60.
In operation, and after a sufficient length of tape T has been laid down on a surface 32, the operator merely depresses the trip 57, which unlatches the knife 37 so as to transversely sever the tape T. Thereafter, the operator merely lifts the knife 37 as by the end handles 37a to relatch the lug 58 within the notch 56a. Urging the latch 56 toward latched position is a coil spring 65 (see FIG. l0), which is confined between the latch member 56 and the ensleeved portion 55a of the ring 55.
,The reservoir 30, as can be appreciated from a comparison of FIGS. l and 6, is equipped with a depending outlet 66 which is equipped with a valve cock 67. Leading from the valve cock 67 is the flexible conduit 35, which is seen to rest on a platform 68 (see the lower portion of FIG. 6) before terminating in the fitting 45. As such, the conduit 35 can be compressed in the fashion shown in FIG. 7 by means of a clamping pin 34 provided as part of the lever 69 -which is pivotally connected as at 33 to the frame 20. The lever 69 is seen to provide an end journal as at 70 (see FIG. l) for the pressure roller 29, and is pivotally mounted as at 33 on the frame 20. The other end of the lever 69 (still referring to FIG. 1) is equipped with an upstanding bracket as at 71 to which is connected a coil spring 72. The coil spring 72 is anchored at its upper end to a post 73 provided on the frame 20. Thus, the spring 72 urges the roller 29 downwardly and the pin 34 into the compressive relation with the conduit 35 shown in FIG. 8. During the step of applying the tape T which is illustrated in FIG. 4, the pressure roller 29 is urged upwardly and against the action of spring 72 so as to relieve the clamped condition of the conduit 35 which is illustrated in FIG. 9. Thus, liquid lis enabled to ow from the reservoir 30 through the conduit 35 into the sponge-like moistureapplying roller 28.
As can be appreciated from a consideration of FIG. 2, the walls 21 and 22 (notably the wall 21 as seen in FIG. 2) are equipped with vertically elongated slots 74 in which a cross shaft 75 is received. The cross shaft 75 in turn is seen to be urged upwardly against the friction wheel 27 by means of a spring 75a suitably anchored to the Wall 21. The unwinding of the tape T drives the applicator roll 2S and at a faster surface speed than the tape Speed to develop an advantageous wiping action relative to the tape and insure proper moistening.
During the operation of threading, the tape T is temporarily supported on a bracket 76 '(see FIG. l2), which is bolted to the anvil 61 (see particularly FIG. 5).
In the operation of the inventive dispenser, it will be seen that the reservoir 30 provides an advantageous means of confining the moistening liquid in a sealed chamber ready for metered discharge when required. The reservoir 30 is seen to be equippedV with removable end caps as at 39a to facilitate filling. However, the dispenser frame 20 can be disposed in any orientation relative to a surface to be taped, i.e., vertical, horizontal, etc.,
without fear that liquid will spill out of the reservoir. It will be appreciated that moistening of the tape is a sine qua non for effective operation of a tape dispenser, and the instant invention insures that moistening can take place irrespective of the orientation of the dispenser. Further, the coaction of the friction wheel 27 and its associated roller 73, with the moistening roll 28, develops the above-described advantageous wiping action to insure full moistening of the tape. Excellent results are obtained when the sponge-equipped roller 28 rotates at a speed about twice that of wheel 27.
While in the foregoing specification a detailed description of an embodiment of the invention has been set down for the purpose of explanation thereof, many variations in the details herein given may be made by those skilled in the art without departing from the spirit and scope of the invention.
