.EAQDLiitl ADHESIVE TAPE DESPENSER Edwin Singer, Brooklyn, N. Y.

Application December 1, wild, Serial No. %,438 3 Claims. (63. ereic) The object of the present invention is to provide a simple and effective device for holding adhesive tens, particularly long-dolled lengths used in hospitals, and for automatically heating the tape it is pulled out of the device, so that the tape may be more readily prepared for immediate use.

Invention will be described with reference to the accompanying drawing, in which- Fig. i. is a. plan view showing an embodiment of the invention partly broken away.

Fig. 2 is a. front elevation, partly broken. away.

Fig. 3 is a sectional elevation extending transversely on the line 3-3, Fig. 2.

Fig. 4 is an enlarged fragmentary end-view of the heating roller showing the mercury switch,

. and stop device.

Fig. 5 is a fragmentary view and elevation, partly in section, howing a roll of adhesive tape adjacent a second roll, and the-lower part of a gauge rod-device.

Fig. 6 is a fragmentary horizontal cross-section, on the line 8-6, Fig. 5.

Fig. '7 is a longitudinal cross-section through the heating cylinder, the latter being broken away at its central area.

Fig. 8 is a wiring diagram.

Referring to the drawing, I have shown at i a casing which may have a removablefront and top member 2 preferably of transparent plastic and slotted for passage of the adhesive tape T.

Secured to the back wall of the casing, are spaced bracket arms 3 formed with slots to'receive a carrying shaft 4 upon which a roll 01' rolls of the adhesive tape are mounted.

At the frontends of the bracket arms 3, the latter are apertured or slotted to receive the shaft 5 of the heating roller. This heating roller is heated by means of a. coil 8 of resistance wire. The core of the roller consists of a tubelike member l of non-conducting material of any suitable kind, or it may be of conducting material wrapped with a sheetd of non-conductinc material. The facing of the heating roller,

indicated at d, is of a material which will freely the roll thereof mounted on shaft 3, the contact I with the tape with the heating; roller will partielly rotate the roller until arms We oi? the stop device contacts with one of the bracket arms 3. This movement will throw the mercury bulb switch to circuit closing position and current will fiow through the coil 8 with the result that heat will be transmitted to the adhesive tepe, the lat tcr having its adhesive face uppermost and not in contact with the roller. Continued movement of the tape will cause it to slide over the heating roller and in such movement to receive heat from the roller.

In the initial operation of the device, the user may give a slight movement to the projecting tape sufficient to close the switch, and hold the tape in such position for very such short inter= val of time as to enable full passage of heat outwardly from coil 6, whereupon the tape may be pulled out to the required length.

My tape holding, heating and dispensing device is particularly desirable for enabling ready bandaging after surgery and in all cases where it is desirable that the adhesive be heated and the tape made ready for instant use. Important fee conduct heat, and it is in the form of a sleeve I internelly supported at its ends by dishs it).

The facing $3 or the heating roller receives apertumd ripples t t through which the conductwires it are led tothe coir as shownin ithin the casing is m electrical. resistance device no. ti" curien' hem. re fiance device to the hcetuic i? mmy ro-E 111 and for hcioihr g some for tote tor of my invention is that a tape may be employed having a, relatively non-tecl-zy characteristic at ordinary room temperatures. so that it may be unrolle-d without resistance from the adherence of convolutions of the tape, the required tacky characteristic being imparted to the adhesive face of the tape only. miter it has been pulled from the convolutions oi the roll.

The top of the cover member 22 is formed with a, plurality of apertures to receive gouge rods ll, the rods at the lower ends carrying rollers it, adapted to contact with the upper sections of the tape rolls. These gauge rods are slidincly mounted in holding brackets is carried by the rear wall of the casing. The front of the casing carries a cutter blade by means of which a length of tape may readily be severed.

Having described my invention whet claim and desire to secure by etters as follows:

i. A dispensing holder for adhesive tape or the r se having one or a of rolis of adhesive 3 tion, said dispensing holder being provided with a heating device over which the tape may be drawn, said heatingdevice comprising a roller inclosing an electrical resistance core and a switch controlling the current to said resistance core, said roller being rotatable by the tape and said rotation of the roller being the switch-closing movement.

2. A dispensing holder for adhesive tape of the type having one or a plurality of rolls of adhesive tape and means for holding the same for rotation, said dispensing holder being provided with a heating device over which the tape may be drawn, said heatin device comprising a roller inclosing an electrical resistance core and a switch controlling the current to said resistance come, said roller being rotatable by the tape. the

latter lying in contact therewith, and said switch device comprising a mercury-bulb carried by the roller. 7

3. A dispensing holder for adhesive tape of the type having one or a plurality of rolls of adhesive tape and means for holding the same for rotation, said dispensing holder being provided with a heating device over which the tape may be drawn, said heating device comprising a roller enclosing an electrical resistance core and a switch controlling the current to said resistance core, said switch comprising a mercury-bulb carried by the roller and said roller being rotatable by the tape and said rotation oi the roller being the switch-closin movement.
