STRIP-SERVING DEVICE.

Specification of Letters Patent,

Patented Feb. '5, 1907.

Application filed October 12,1905. Serial No. 282,388.

To all whom it may concern:

Be it known that I, STERLING ELLIOTT, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Strip- Serving Devices, of which the following is a specification. This invention relates to devices or apparatus for supplying strips of paper employed for Wrapping or binding packages, and has particular reference to that type of apparatus of this character employing a support for a coil of the paper strip which has been previously gummedon one side and then dried, and having means for moistening the gummed side of the strip as the latter is drawn from its coil, and having also means for raising or lifting the free end of the strip after the pormg means whereby the moistener will be automatically lifted intoa proper place for con-' tact with the strip and so as to automatically drop from that plane when the strip is released, the strip being at the same time pref erably raised somewhat from its former position to prevent any possibility of anypart of the strip resting for any period of time in contact with the moistener.

To this end the invention consists in the construction and combination of parts substantially as hereinafter described and claimed Of the accompanying drawings,*Figure 1 is a side elevation representing the invention. 2 represents an endview of .the same from the right of Fig. 1. Fig. 3 is a view similar to a portion of Fig. 1, but showing.

the parts in a different position.

Similar reference characters indicate the same or similar parts throughout the several vlews. I

Upon a base 10 is suitably supported a casing 1 1 for the roll or coil of the paper strip, or it may be supposed to be a reel for such a strip. If desired, the casing 1 1 may be provided with distinct strip-tensioning means of any suitable type, such as the clampingscrew 11', Fig. 2, although in practice the strip is sufficiently tensioned by the weight and disposition of the parts; Mounted upon the base 10 is a tank or reservoir 12 to contain wateror an adhesive, according to whether the device is tobe used for serving a gummed or an ungummed strip. A'frame 1.3 is 'piv-' iOted at 14 within said tank near the top thereof, and is provided at its rear end with a combined guide and lifting bar 15. Tothe end of the frame within the tank is secured amoistener 16 .of suitable material adapt-ed to raise the liquid in the tank by capillary attraction; The upper edge of the front wall OfthG tank is indicated at 17 and forms the guide or support for the free end of the strip when the device is not in user A cutter of an ordinary form is' shown at 18, said .cutter being some little distance above the guide or support 17. A horizontal plate or bar 19 (represented by dotted lines in Figs. 1 and 3) extends across between the sides of the tank or reservoir in substantially the same plane as the edge 17. In operation the strip 20 is drawn from the casing 11 over the combined guide and lifting bar 15 and over the plate 19 and between the edge 17 and cutter 18; When the free end of said strip is drawn directly outward in a substantially horizontal 'plane, as represented. in Fig. 3, the resistance to the movement of the strip aflorded by the cpil of material within the casing 1 1 produces a ten sion which is the equivalent of 'a weight upon the bar 15, the resulting pressure being suflicient to oscillatethe frame 13 and bring the moistener 16 above the-plane of the plate 19* and edge 17. When 'a' sufficient length has been drawn oil", the operator raises the strip, so as tosever it against the'cutter 18 and then thefree end drops to the position shown in Fig. 1, or it may, being slack, rest directly upon the plate or bar 19, which thus serves as a support for the strip atapoint intermediate the moistener and bar. a The release of the tensionupo'n the strip relieves the pressure upon the bar 15, so that the inner portion of the frame 13 and the moistener car ried thereby will immediately dro so that the u per end of the moistener w 'be below the pi ane of plate 19 and the edge of 17, on

which the free endof the strip rests. At'the same time upward movement of the bar 1 5 causes; it to act asalifter tdgraise the strip, and aid'in preventing any possibility of its remaining incont'act with any portion of the apparatusflo which it might stick if allowed "torest. f -1- 'Theplateor bar 19 is .not an absolute'necessity; but I prefer to employ it to prevent any liability of the strip between the bar and the edge -17 from bending down; far enough tocome in conta'ctwith the end of the j moisteners Instead of employing the cutter 18 the upper edge 17 of the front wall of the tank might beut-ilized as the cutter or means for severing the strip Having now described my invention,

claim- 1. An apparatus of the character'specified, comprising a tank or-reservoir, 'a-moistener pivoted therein and a strip-lifter connected with.said moistener to oscillate therewith, said strip-lifter being adapted-to raisethe moistener when pressure is exertedthereupon by'a pulling movement of the strip:' 1

I 2. An apparatus of the character-specified,

comprising a tank or reservoir, a pivoted frame having a bar at oneend outside the I tank and having a moistener at the other end within the "tank, and ja supportfor-a coilof paper, whereby a pull upon the strip leading 'over the said'barfwill depress that portion of the frame and elevate the moistener "against.

theunder' side of the strip. f s

3. An apparatus of the character specified,

comprising a tank or reservoina pivoted frame having a bar at one'end outside the tank and having amoistener at the other, end within the tank, and'a support-fore coil ofpaper, whereby a .pull upon 'thestripleading over the said bar will depress thatportion of the frame and elevate the moistenera ainst the under side of the strip, a support eing provided for the strip at a point intermediate the moistener and said bar. J

4. apparatusof he character specified, comprising a tank or reservoir having an opening in its uppersin-face-across whichv the strip of gummed paper may rest; a moist-en:

mg deviceiwithin the tank, and means automatically to'raise or lower said moistening device into or out of contact withthe strip of paper when the latter is 'drawn'for use or released. I y y I 5. Astrip-servingglev'ice comprising means for delivering a strip, stripemoisteningmeans normally in inactive relation thereto, and means automatically to-move' said moistene mg means frominactive to active relation to said strip fonmoisteningthe latter for use.

6. In an apparatus of the character specified a tank or reservoir, a moistening device .moistening device to normally in moisture-receiving relation thereto, strip-guiding means and means controlled by draftpf the stri for use, to move said moistening device 'om molsture-receivmg relation to strip-moistening relation.

9. A tape-moistener comprising means for" restraining, directing and positioning a strip -'of gummed tape, movable molstenmg means,

and mechanism actuated by'said movable moistening means for separating the end of the'tape' and the surface of said moistening means after the tape has been fed and severed.

10. A tape-moistener comprising means to restrain, guide and position a strip of gummed tape, movable moistening means, and mechanism connecting the tape therewith, such that varying feeding stress in the tape will change the position of the moistening means with relation to the tape.
